[0020] The upper half width of jig module 10 matches the upper half width of push T groove 2 requires that the upper half width of jig module 10 is 0.8-1.5mm less than the upper half width of push T groove 2, so that pushing does not jam, and the pushing process is also easy to slide, and the jig module 10 is a stainless steel metal block, and the side wall is smooth.

[0021] The jig module 10 is pushed to the input end of the pushing conveyor belt 3, and the pushing plate 31 is arranged to have a certain extrusion positioning on the jig module 10 after being pushed to the limiting stop mechanism. When the first pushing block 6 is pushed out by the first pushing cylinder 61, the jig module 10 cannot be accurately pushed into the clamping T-shaped groove 8 (the lowered connection rail 7 is lowered first to prevent blocking the lower half of the jig module 10), and the jig module 10 is pushed against the inner wall of the clamping T-shaped groove 8. At this time, the clamping hydraulic cylinder 41 presses the clamping plate 42 downward to extrude and fix the upper surfaces of the two side edges of the jig module 10, and the machining of the CNC part on the jig module 10 is started. After machining, the clamping plate 42 is raised, the clamping and fixing are released, the second pushing block 9 is pushed out by the second pushing cylinder 91 (when pushed out, the docking cylinder 301 pushes out the docking movable slide rail 30, which is convenient for the jig module 10 to slide to the docking movable slide rail 30, until it is completely placed on the two slide rails in the pushing T-shaped groove 2, and then the docking movable slide rail 30 is withdrawn), and the jig module 10 is pushed out to the pushing T-shaped groove 2. After that, continue to push backward, wait for the next jig module 10 to arrive, and perform the above process.

[0022] The top of the pushing plate 31 does not expose the top of the lower half of the pushing T-shaped groove 2, the two ends of the pushing plate 31 are rearwardly extended arc-shaped plates, and the width of the pushing plate 31 is 2 / 3 of the width of the lower half of the pushing T-shaped groove 2.

[0023] The height is not high enough to block the bottom of the upper half of the jig module 10, and the rearwardly extended arc-shaped plate is used to push the jig module 10 to the clamping T-shaped groove 8, and then push it back to the inside of the pushing plate 31 at this position, or push it to the clamping T-shaped groove 8, and then reverse the pushing conveyor belt 3 by 2-3 cm, which is more conducive to pushing back.

[0024] The limiting stop mechanism includes a limiting stop block 5 and a limiting pushing cylinder 51, the limiting stop block 5 is provided with two limiting pushing cylinders 51, and the limiting pushing cylinders 51 are installed on the jig base 1 through mounting frames.

[0025] A start-stop button is arranged on the side wall of the limiting stop block 5, and when the jig module 10 touches and extrudes the start-stop button, the pushing conveyor belt 3 stops running, so that the jig module 10 is clamped.

[0026] The upper surface of the jig module 10 is provided with a CNC part clamping groove, and the CNC part clamping groove is arranged according to the contour matching of the CNC part.

[0027] Different CNC parts correspond to different CNC part clamping grooves, but the outer contour of the jig module 10 is the same, and multiple CNC parts are used for machining and clamping.

[0028] The length of the pushing T-shaped groove 2 is 7-10 times the width of the jig module 10, and the spacing between adjacent pushing plates 31 is 2-3 times the width of the jig module 10.

[0029] The length of the pushing T-shaped groove 2 is 7-10 times of the width of the jig module 10, which can ensure that there are at least two pushing plates 31 on the pushing conveying belt 3, and sometimes three (such as Figure 3 ), to ensure that one is clamped for processing. The other has arrived at the pushing conveying belt 3 and waits for clamping processing, facilitating continuous operation replacement.

[0030] When the jig module 10 is pushed by the pushing plate 31 and abuts against the limiting stop mechanism, a stop button provided on the limiting stop mechanism will be triggered. The stop button is a pressure switch and a magnetic induction switch.

[0031] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
