[0036] The positioning mechanism includes a protective shell 4, an inner shell 5, a T-block 6, an inner support 7, a hydraulic cylinder 10, a clamping positioning block 11, a positioning head 12 and a disassembly and cleaning unit;

[0037] The protective shell 4 is fixedly installed on the top of the medium-speed wire cutting machine body 1, the inner shell 5 is fixedly installed inside the protective shell 4, the T-block 6 is clamped with the inner shell 5, the inner support 7 is fixedly installed on the top of the T-block 6, the hydraulic cylinder 10 is fixedly installed on the side of the protective shell 4, the hydraulic rod of the hydraulic cylinder 10 is fixedly connected to the clamping positioning block 11, and the side of the clamping positioning block 11 is fixedly connected to the positioning head 12;

[0038] By means of the positioning mechanism, the workpiece 8 is placed on the top of the inner support 7, and the hydraulic cylinder 10 is started, so that the clamping and positioning block 11 drives the positioning head 12 to move, and the two positioning heads 12 can clamp and fix the workpiece 8, and then the workpiece 8 is cut by the cutting assembly 3 above. The specific structure of the cutting assembly 3 can refer to the comparative document with the announcement number CN220112505U, which is the prior art and will not be described in detail here;

[0039] The disassembly and cleaning unit includes a filter plate 9, a square plate 14, a spring 16, a baffle 17 and a side support 18. The filter plate 9 is fixedly installed on the T-block 6.

A rectangular hole 15 is provided on the top of the clamping positioning block 11, and the top of the square plate 14 passes through the rectangular hole 15.

[0040] Through the above-mentioned disassembly and cleaning unit, after the workpiece 8 is processed, the hydraulic cylinder 10 is started to separate the positioning head 12 from the workpiece 8, and then the workpiece 8 is removed. The workpiece 8 will spray cutting fluid during the processing, and the cutting fluid will flow down through the filter plate 9, and the filter plate 9 will separate the impurities. When the filter plate 9 needs to be cleaned, the hydraulic cylinder 10 can be continued to be started to make the clamping positioning block 11 continue to move. After the inner wall of the side of the rectangular hole 15 contacts the square plate 14, it will drive the square plate 14 to move, and the square plate 14 will drive the baffle 17 to move, so that the baffle 17 is separated from the side support 18. In this process, the square plate 14 will squeeze the spring 16, and then pull the inner support 7 upward, so that the filter plate 9 can be removed for cleaning. The steps are relatively simple and convenient to use.

[0041] Specifically, a workpiece 8 is placed on the top of the inner support 7, and the side of the positioning head 12 abuts against the workpiece 8. The positioning head 12 is located above the T-block 6. It should be noted that

The clamping and positioning block 11 is an L-shaped structure. It should be noted that it is convenient for the clamping and positioning block 11 to move stably in the lateral direction.

[0046] Specifically, the side surface of the square plate 14 contacts the side wall of the back groove 13 . It should be noted that the square plate 14 may be subjected to a position limiting process.

[0047] Working principle:

[0048] S1: Place the workpiece 8 on the top of the inner support 7, start the hydraulic cylinder 10, so that the clamping and positioning block 11 can drive the positioning head 12 to move, and the two positioning heads 12 can clamp and fix the workpiece 8, and then the workpiece 8 is cut by the cutting assembly 3 above. After the workpiece 8 is processed, start the hydraulic cylinder 10 to separate the positioning head 12 from the workpiece 8, and then remove the workpiece 8. During the processing, the workpiece 8 will spray the cutting fluid, and the cutting fluid will flow down through the filter plate 9, and the filter plate 9 will separate the impurities;

[0049] S2: When the filter plate 9 needs to be cleaned, the hydraulic cylinder 10 can be started again to make the clamping positioning block 11 continue to move. After the inner wall of the side of the rectangular hole 15 contacts the square plate 14, the square plate 14 will be driven to move. The square plate 14 will drive the baffle 17 to move, so that the baffle 17 is separated from the side support 18. During this process, the square plate 14 will squeeze the spring 16, and then pull up the inner support 7, so that the filter plate 9 can be removed for cleaning, that is, the staff only needs to pull up the inner support 7. The steps are relatively simple and convenient to use.
