The rest of the integrated acceptance mold mouth is inspected and adjusted. 4 Accessories and tools
The following accessories and tools should be supplied by the insurance company:
, special cover, one set,
, lubricating oil push. - Parts:
T, anchor bolts, wipe, seat feel, adjustment seat iron, one change. 5 Safety and Health
5.1 The upper workbench should be oiled and the bottom effect button can be opened after the customer starts. 5.3 The left workbench is in normal operation. The horizontal beam is locked before the service card begins. 5.3 When the load stops rotating, the feed motion should be stopped first. 5.4 When the horizontal and vertical frames move to the limit position, the two-stop protection device should be installed. 5.5 The guide rail should have a protective device.
5.6 According to the provisions of ZBJ50004, the noise level of the machine tool is tested under the narrow operating conditions of low, medium and high speed. The noise level of the machine tool is 1596411 approved by the Ministry of Machinery Industry of the World Bank. 1996-[(-01 The actual machine level should not be A).
JB/T 8328.2-96
5.7 The operating force of the hand wheel used for the start of the motor should not be greater than 120N: the operating force of the other hand wheels and handles should not be greater than 200N. 5.8 When inspecting the machine tool according to this standard, the other acceptance items specified in JB4139 and GT5226GH6576 and 7B15116 should be inspected at the same time. 6 Machining and assembly
6.1 The workbench base, bed guide, mold beam, fixed rail, soil change box, straight tool holder slide are important castings, and aging treatment should be carried out after rough machining. The main wear parts such as worm gear pair, screw pair, clutch and other parts should be treated with aging treatment corresponding to the service life. .3 The swivel seat and the vertical tool holder are made of guide rails, such as the tool holder body and the submersible speed rail pair, the horizontal slide and the inspection beam guide pair. The frame body and the vertical pull rail, the horizontal frame and the vertical guide rail are important guide rails. Wear-resistant iron, calcium-inlaid guide rails, plastic guide rails should be used. High! Medium frequency induction fire and other service measures
and, 4 The following joint surfaces should be checked according to the "Requirements for Fixed Joint Surfaces": the joint surface of the bed body when standing;
b, the joint surface of the work base and the safety manure
: the joint surface of the bed body and the screen laugh:
l The joint surface of the beam lifting reducer and the drilling column, the joint surface of the wire support and the base: the joint surface of the base. | |tt||Heart.5 The following requirements are required for the "special connection": g,
The connection surface between the rotary table of the blade rack and the knife: h.
The connection surface between the rotary table of the vertical rack and the ram: h.
The connection between the return island and the horizontal seat;
The connection between the four-way force and the belt,
6.6 The connection between the horizontal and the column guide rail The guide rail pair should be inspected as sliding guide pillow. 6. The following positioning pins should be adjusted and their contact length should not be less than 60% of the working depth: A. Positioning pins between the base and the base;
6. Positioning pins of the tool table positioning plate;
Positioning cone pins of the adjustment channel of the light bar and the fire bar. c.
6.8 The horizontal and multi-feed wheel handle with measuring device can be empty 6. Check the cleanliness of the main transmission box and feed box, liquid outlet box and lubricant box according to the provisions of ZBJ50CC3. The cleanliness of the main transmission box and feed box, liquid outlet box and lubricant box should be sampled and inspected. The prohibited factors and contaminants should not exceed: main transmission pin and feed pin 4mL: liquid pin and lubricant tank 3g/L.
6 Machine tool idle running test
.! The machine tool ten stealing mechanisms start from the lowest speed ·Operate in sequence. The operation time of each speed level should not be less than 32min. The high speed should not be less than 1 minute. When the workbench reaches the set speed, measure the auxiliary bearing withdrawal angle and the group rise behind the inner end plate of the workbench: the maximum bearing plate should not exceed 70°C, the thrust bearing should not exceed the maximum lift, and the resistance rise should not exceed 30°C. The temperature rise test span of the hydraulic system shall comply with the provisions of ZBJ59016. The speed of the 2 axis rotation of the workbench and the speed of the feed rate should not exceed 36% of the value indicated on the label. 7.3 The rack should be tested for rapid movement and empty operation. During the test, the rack should be tested for reliability twice. The vertical tool holder and the side tool holder should be started and stopped 5 times in a row to test the reliability of the operation. 2||tt ||/T8328.2—96
The beam is lifted and lowered 9 times in full swing, and the lifting screw nut is pulled. If there is any problem, the main drive is started and stopped in the forward and reverse directions at an appropriate speed. The speed of the main drive system is controlled at an empty speed (excluding the no-load power of the main motor). The speed does not exceed 25% of the design power. B Machine tool load test
3.1 This series of machine tools should be subjected to the following load tests: u. Operation test of the maximum weight of the workpiece the machine tool bears (spot check) n.
Maximum power test of the main transmission system of the machine tool (spot check); main component force test of the machine tool main transmission system:
Maximum torque test of the main transmission system of the machine tool,
c: Test of the main component of the machine tool in the transmission system with a maximum torque and maximum shear resistance exceeding the design requirements. 82 The machine tool load-bearing workpiece is operated with the maximum load of the workbench and the high load specified in the design. The maximum power is the power specified in the investment certificate. 1. The main component of the maximum cutting force of the main transmission system of the machine tool is tested in a short time with the maximum torque specified in the design: the test time is not less than 1min
, the maximum torque is less than 1min, that is, the maximum main component of the forward resistance (T), the formula has been calculated, T=9550P.P)
where, T—cutting component force.N
,
1—free motion rate (with parts), W;.. cutting diameter.n.
F spindle speed.1/min.
8.5 When testing various loads, the machine tool works properly and reliably. The machine tool precision inspection
9.1 The precision inspection of the machine is generally carried out in accordance with JB/T8728.1. 9.2G8 and GS should be tested when the stability group is in the machine tool. 9.3 Working precision test specification According to the design document: P
