[0033] Example 1

[0034] PVC pipes are relatively hard. If there is shaking when drilling holes in PVC pipes, the size of the holes will be different from the expected size, and the shape of the holes will also be irregular, making it difficult to control the spraying water pressure. At the same time, when drilling holes in PVC pipes, it is necessary to ensure that the PVC pipes do not deviate. Therefore, please refer to Figures 1-9As shown, the purpose of this embodiment is to provide a punching device for PVC pipe processing that prevents pipe deformation, including a fixing device 1 and a drilling device 2 arranged on one side of the fixing device 1, the fixing device 1 includes a base 11, a slide groove 12 is provided on the top of the base 11, and a positioning structure is provided on the top of the base 11, the positioning structure is used to fix the position of the PVC pipe, the drilling device 2 includes a clamping mechanism 21, the clamping mechanism 21 includes two clamping plates 215, and a drilling mechanism 22 is provided on one side of the clamping plate 215. The drilling mechanism 22 is used to drill holes in the PVC pipe, and a synchronous structure is provided at the bottom of the clamping plate 215. When the drilling mechanism 22 drills holes in the PVC pipe, the synchronous structure drives the clamping plate 215 to clamp the PVC pipe. When the drilling mechanism 22 finishes drilling holes in the PVC pipe, the synchronous structure drives the clamping plate 215 to lift the PVC pipe, and the synchronous structure slides in the slide groove 12.

[0035] The PVC pipe is installed on the positioning structure, and the positioning structure positions the PVC pipe to prevent it from shaking. When the drilling mechanism 22 cuts the PVC pipe, the synchronous structure drives the clamping plate 215 to further clamp and fix the PVC pipe to prevent the PVC pipe from shaking during cutting. After the cutting is completed, the synchronous structure drives the clamping plate 215 to rotate and lift the PVC pipe upward. At this time, the PVC pipe can be adjusted to facilitate the next step of drilling the PVC pipe.

[0036] When drilling holes in PVC pipes, in order to avoid shaking or deflection of the PVC pipes, please refer to Figure 2 As shown, the positioning structure includes a vertical plate 13, which is fixedly arranged on the top of the base 11. A fixing plate 14 is fixedly connected to one side of the vertical plate 13. The vertical plate 13 is used to determine the position of the fixing plate 14, and the fixing plate 14 is used to help determine the position of the PVC pipe.

[0037] The top of the fixed plate 14 is fixedly connected to a number of sleeve rods 15, and the top of the sleeve rod 15 is plugged with an insertion rod 16. The sleeve rod 15 is used to determine the movement trajectory of the insertion rod 16. The bottom end of the insertion rod 16 is fixedly connected to a thrust spring 18. The thrust spring 18 is used to give the insertion rod 16 an upward thrust. The bottom end of the thrust spring 18 is fixedly connected to the sleeve rod 15. A support plate 17 is provided on the top of the insertion rod 16. The support plate 17 and the fixed plate 14 cooperate to position the PVC pipe. The support plate 17 and the insertion rod 16 are fixedly connected.

[0038] To avoid deflection of the PVC pipe during drilling, refer to Figure 2-Figure 3 As shown, one end of the support plate 17 and the fixing plate 14 are both configured as friction plates, which are used to increase the friction force in contact with the PVC pipe to prevent the PVC pipe from deflecting.

[0039] Before drilling the PVC pipe, put the PVC pipe on the outside of the fixed plate 14. Under the action of the elastic force of the thrust spring 18, the insertion rod 16 is driven to move upward, and the insertion rod 16 drives the support plate 17 to move upward. The support plate 17 and the fixed plate 14 cooperate to position the PVC pipe. At this time, the support plate 17 and the friction plate on the fixed plate 14 cooperate to prevent the PVC pipe from deflecting.

[0040] When drilling holes in PVC pipes, the synchronous structure drives the clamping plate 215 to clamp the PVC pipe and drives the PVC pipe to move downward to overcome the elastic force of the thrust spring 18. At this time, the clamping plate 215 supports the PVC pipe on the outside of the PVC pipe, and the support plate 17 supports the inside of the drilling position of the PVC pipe to avoid deformation and rupture of the PVC pipe during the drilling process. Compared with the common PVC pipe drilling method, the method can effectively avoid deformation and rupture of the PVC pipe when drilling holes in the PVC pipe, and avoid deviation and shaking of the PVC pipe during the drilling process, and the shape and size of the drilled hole can be controlled more accurately.

[0041] When drilling holes in PVC pipes, in order to secure the pipes more firmly and move them downwards, please refer to Figure 4-Figure 6 As shown, the synchronization structure includes two rotating rods 214, which are fixedly connected to two clamping plates 215 respectively. The rotating rods 214 are used to drive the clamping plates 215 to move, and a tension structure is provided at the bottom of the rotating rods 214.

[0042] The pulling structure includes a lifting plate 212, and the two ends of the lifting plate 212 are hinged with hinged rods 213. The lifting plate 212 is used to drive the hinged rods 213 to move. The two hinged rods 213 are respectively hinged to the two rotating rods 214. The bottom end of the lifting plate 212 is fixedly connected with a lifting spring 218, and the lifting spring 218 is used to give the lifting plate 212 an upward thrust.

[0043] The bottom end of the lifting spring 218 is fixedly connected to the sliding frame 211, which is slidably set on the top of the sliding groove 12. The rotating rod 214 and the sliding frame 211 are hinged. The sliding frame 211 is used to drive the rotating rod 214 to move and determine the position of the rotating rod 214.

[0044] When cutting PVC pipe, please refer to Figure 8 As shown, slide the sliding frame 211 to a suitable position, press the lifting plate 212 to overcome the elastic force of the lifting spring 218 and move downward, the lifting plate 212 drives the hinged rod 213 to move downward, the hinged rod 213 drives the rotating rod 214 to rotate, and the rotating rod 214 drives the clamping plate 215 to move to clamp and fix the PVC pipe, thereby completing the cutting;

[0045] When the cutting is complete, see Figure 9 As shown, the lifting spring 218 pushes the lifting plate 212 to move upward, the hinged rod 213 drives the rotating rod 214 to rotate, and the rotating rod 214 drives the clamping plate 215 to move, thereby lifting the PVC pipe upward. During the lifting process, a certain clamping effect on the PVC pipe is maintained to ensure that the PVC pipe will not deflect when moving upward.

[0046] For fast and efficient drilling of PVC pipes, see Figure 7 As shown, the drilling mechanism 22 includes a lifting frame 221, a limiting block 216 is fixedly connected to one side of the sliding frame 211, the sliding frame 211 and the limiting block 216 are slidably connected, the limiting block 216 is used to limit the moving trajectory of the lifting frame 221, and a drilling structure is provided at one end of the lifting frame 221.

[0047] The drilling structure includes a motor 222, which is fixedly arranged at the top of the lifting frame 221. A drill bit 223 is provided at the bottom of the motor 222. The drill bit 223 is rotatably connected to the lifting frame 221. The drill bit 223 and the output shaft of the motor 222 are coaxially connected. The motor 222 is used to drive the drill bit 223 to rotate, and the drill bit 223 is used to drill holes in PVC pipes.

[0048] In order to drive the lifting plate 212 to move synchronously when drilling the PVC pipe, please refer to Figure 7 As shown, the synchronization structure also includes a synchronization rod 224, and the two ends of the synchronization rod 224 are fixedly connected with a shift rod 225. When the lifting frame 221 moves downward, the bottom end of the lifting frame 221 is in contact with one side of one of the shift rods 225, and the other shift rod 225 is in contact with the lifting plate 212. The outer wall of the synchronization rod 224 is sleeved with a positioning block 217. The positioning block 217 is used to determine the position of the synchronization rod 224. The positioning block 217 is fixedly connected to the sliding frame 211.

[0049] When drilling a hole in a PVC pipe, the lifting frame 221 is pressed downward, and the motor 222 drives the drill bit 223 to rotate. After moving downward, the lifting frame 221 is fitted with one of the levers 225, and the synchronizing rod 224 is driven to rotate through the lever 225. At this time, the other lever 225 drives the lifting plate 212 to move downward, and the drill bit 223 drills a hole in the PVC pipe, thereby achieving the effect of synchronous operation of the drill bit 223 and the clamping plate 215, strengthening the fixation of the PVC pipe during drilling, and the PVC pipe can be adjusted as needed after drilling is completed.
