A limiting block 406 is arranged on one side of the spring 405, and a positioning rod 407 is arranged on one side of the limiting block 406. A protective block 408 is arranged at one end of the positioning rod 407.

[0027] In this embodiment, the cooling assembly 3 includes a water storage box 301, a filter plate 302, a water suction pipe 303, a water pump 304, a water delivery pipe 305, a fixing member 306, a telescopic bellows 307 and a nozzle 308. The filter plate 302 is provided on the front of the water storage box 301. The front of the water storage box 301 is provided with a mounting groove adapted to the size of the filter plate 302. The filter plate 302 is mounted on the water storage box 301 through a chimeric connection. A water suction pipe 303 is provided on the lower side of the water storage box 301. A water pump 304, model 25LG3-10x3, is provided at the top of the water suction pipe 303. A water delivery pipe 305 is provided at the output end of the water pump 304. A fixing member 306 is provided at the top of the water delivery pipe 305. A telescopic bellows 307 is provided on one side of the fixing member 306. A nozzle 308 is provided at one end of the telescopic bellows 307.

[0028] Specifically, the filter plate 302 can be used to filter the used water so that it can be recycled. When the filter plate 302 is damaged, it can be directly replaced by pulling it out.

[0029] In this embodiment, one end of the water pumping pipe 303 is fixedly connected to the water storage box 301, and the other end of the water pumping pipe 303 is fixedly connected to the water pump 304. The two sides of the bottom end of the water storage box 301 are inclined.

[0030] Specifically, by starting the water pump 304, the water source inside the water storage box 301 can be better pumped out for spraying treatment;

[0031] In this embodiment, the telescopic bellows 307 is composed of a plurality of groups of movable sleeves. One end of the telescopic bellows 307 is fixedly connected to the fixing member 306, and the other end of the telescopic bellows 307 is fixedly connected to the nozzle 308.

[0032] Specifically, it is convenient to move the nozzle 308 to a designated position by pulling the telescopic bellows 307 so as to better cool the contact point between the processing mechanism 2 and the workpiece;

[0033] In this embodiment, one end of the electric push rod 402 is fixedly connected to the fixed plate 401, and the other end of the electric push rod 402 is fixedly connected to the clamping plate 403. There are two groups of clamping plates 403, and the two groups of clamping plates 403 are arranged in the middle of the housing 1 corresponding to each other;

[0034] Specifically, by starting the electric push rod 402, the clamping plate 403 is pushed to position and clamp the workpiece, thereby improving the positioning effect of the workpiece;

[0035] In this embodiment, the size of the limit block 406 is adapted to the size of the groove 404. The limit block 406 is fixedly mounted on the positioning rod 407, and the limit block 406 is slidably connected to the inner wall of the groove 404.

[0036] Specifically, the positioning rod 407 is limited by the limiting block 406 to prevent it from being separated from the inside of the groove 404 and affecting normal use;

[0037] In this embodiment, the protective blocks 408 are mounted on the positioning rods 407 by adhesive connection. There are several groups of protective blocks 408, and the protective blocks 408 are arranged in a rectangular array.

[0038] Specifically, the protective block 408 can prevent the clamping force of the clamping plate 403 from being too strong and causing wear when the clamping plate 403 contacts the workpiece, while making the positioning rod 407 closer to the workpiece, further improving the positioning and fixing effect of the workpiece.

[0039] The working principle and use process of the present invention are as follows: when positioning, the workpiece to be processed is first placed between the two groups of clamping plates 403, and then the electric push rod 402 in the positioning assembly 4 is started to push the clamping plate 403 to position and clamp the workpiece. At the same time, during the positioning and clamping process, the workpiece is first contacted with the positioning rod 407 on the limit block 406, so that the limit block 406 squeezes the spring 405 in the groove 404, and then drives the positioning rod 407 at the position corresponding to the workpiece to move backward in sequence, so that the workpiece can be positioned and fixed by several groups of mutually cooperating positioning rods 407, thereby improving the positioning and fixing effect of the workpiece. Finally, the protective block 408 is provided to prevent the clamping force from being too large when the clamping plate 403 contacts the workpiece. As it wears, the positioning rod 407 is made closer to the workpiece, further improving the positioning and fixing effect of the workpiece. When processing the workpiece, the nozzle 308 in the cooling component 3 is moved to the specified position by pulling the telescopic bellows 307, and then the water pump 304 is started to make the water pipe 303 draw out the water source in the water storage box 301 and discharge it into the water pipe 305, and then rise from the water pipe 305 to the fixing part 306, and then rise from the fixing part 306 to the telescopic bellows 307, and finally spray it on the contact point between the processing mechanism 2 and the workpiece through the nozzle 308 to achieve rapid cooling of the workpiece. Finally, the used water source can be filtered through the filter plate 302 for recycling.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
