Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Please see Figure 1-4This utility model provides a technical solution: a CNC machining positioning point delay avoidance fixture, including a base plate 1, a support column 2 fixedly installed on the top of the base plate 1, a machining table 3 fixedly installed on the top of the support column 2, a positioning clamping delay avoidance component 4 fixedly installed on the top of the machining table 3, a second cylinder 5 fixedly installed on the bottom of the base plate 1, a telescopic column 6 fixedly installed on the movable end of the second cylinder 5, a clamping head 7 fixedly installed on the end of the telescopic column 6 away from the second cylinder 5, a third cylinder 8 fixedly installed on the top of the base plate 1, a top column 9 fixedly installed on the movable end of the third cylinder 8, and a workpiece 10 provided on the top of the positioning clamping delay avoidance component 4.

[0021] Furthermore, the positioning, clamping, delay, and avoidance assembly 4 includes a cylinder 401, a telescopic rod 402, a threaded hole 403, a support plate 404, a support plate 405, a clamping head 406, a square hole 407, a rotating roller 408, a rotating roller 409, a support block 410, a positioning post 411, and a positioning block 412. The cylinder 401 is fixedly mounted on the top of the base plate 1. The telescopic rod 402 is fixedly mounted on the movable end of the cylinder 401. A threaded hole 403 is provided on the outer side of the telescopic rod 402. The support plate 404 is fixedly mounted on the top of the base plate 1. The support plate 405 is fixedly mounted on the end of the telescopic rod 402 away from the cylinder 401. A clamping head 406 is rotatably mounted on the top of the support plate 404 and the second support plate 405 via rotating rollers 408 and 409. A square hole 407 is opened on the top of the clamping head 406. A support block 410 is fixedly mounted on the top of the base plate 1. A positioning post 411 is fixedly mounted on the top of the support block 410. A positioning block 412 is fixedly mounted on the outside of the positioning post 411. The telescopic rod 402 is threadedly connected to the second support plate 405. The first rotating roller 408 and the second rotating roller 409 are the same size and structure. By setting the positioning clamping delay avoidance component 4, it is beneficial to protect the positioning point from the impact and vibration during the processing, thereby improving the processing accuracy and workpiece quality.

[0022] Furthermore, the positioning block 412 contacts the workpiece 10, and the clamping head 406 contacts the workpiece 10. Through the cooperation between the positioning block 412 and the workpiece 10 and the clamping head 406 and the workpiece 10, the workpiece 10 can be fixed more stably, thereby facilitating its processing and production.

[0023] Furthermore, the support plate 404 is rotatably connected to the rotating roller 408, and the support plate 405 is rotatably connected to the rotating roller 409. Through the cooperation between the support plate 404 and the rotating roller 408 and the support plate 405 and the rotating roller 409, the lifting height of the cylinder 401 can be adjusted according to the height of the workpiece 10.

[0024] Furthermore, the diameter of the square hole 407 is larger than the width of the second support plate 405. The first support plate 404 and the second support plate 405 do not contact each other. Through the arrangement of the first support plate 404 and the second support plate 405, the clamping head 406 can be better adjusted.

[0025] Furthermore, the telescopic column 6 penetrates the base plate 1 and extends above the processing table 3, and the clamping head 7 contacts the workpiece 10. Through the arrangement of the clamping head 7 and the workpiece 10, the workpiece 10 can be firmly clamped.

[0026] Furthermore, two identical positioning and clamping delay avoidance components 4 are provided, and the two positioning and clamping delay avoidance components 4 are equally distributed above the processing table 3. By setting two sets of positioning and clamping delay avoidance components 4, the working cycle time is reduced, the processing efficiency is improved, and the practicality is high.

[0027] Furthermore, two identical cylinders are provided for cylinder 2 5, telescopic column 6, clamping head 7, cylinder 3 8, and top column 9. The two sets of cylinder 2 5, telescopic column 6, clamping head 7, cylinder 3 8, and top column 9 are equidistantly distributed above the base plate 1. By setting up two sets of cylinder 2 5, telescopic column 6, clamping head 7, cylinder 3 8, and top column 9, the processing efficiency is improved and the working cycle time is reduced.

[0028] Working principle: During operation, the operator first opens all cylinders 401 (first cylinder), 5 (second cylinder), and 8 (third cylinder). Then, the operator places the two workpieces 10 to be processed above the support block 410. The operator then activates cylinder 401, causing the telescopic rod 402 to move, which in turn rotates rollers 408 and 409, thereby moving the clamping head 406. This clamping head 406 then contacts the workpiece 10, clamping and fixing it in place. Simultaneously, cylinder 5 activates, causing the telescopic column 6 to move up and down, which in turn moves the pressing head 7 up and down, bringing it into contact with the workpiece 10 and clamping and positioning it. The operator starts cylinder 3 (8), which moves the top column 9 up and down, so that the top column 9 contacts and positions the workpiece 10. Finally, the workpiece 10 contacts the positioning block 412, thus completing the clamping and positioning of the workpiece 10 and ensuring that the workpiece 10 will not shake during processing. After the workpiece 10 is processed, the operator first closes cylinder 3 (8), which releases the top column 9 from the workpiece 10. Then, cylinder 2 (5) is closed, and finally cylinder 1 (401) is closed. At this point, the operator can remove the processed workpiece 10. Repeating the above process can process all the workpieces 10 that need to be processed. The operation is simple and convenient.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
