[0012] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0013] The technical solution specifically implemented in this utility model is:

[0014] like Figure 1 and Figure 2 As shown, a trimming device for plastic valve production comprises a base plate 1, a bracket 2 is provided on the base plate 1, a flip assembly 3 is movably provided on the bracket 2, a mounting seat 4 for fixing the plastic valve is provided on the flip assembly 3, a translation assembly 5 which can be moved away from or close to the mounting seat 4 is provided on the base plate 1, a grinding assembly 6 is provided on the slide plate 51 of the translation assembly 5, and a grinding disc 61 of the grinding assembly 6 faces the mounting seat 4; the flip assembly 3 comprises a pair of rotating shafts 31 fixedly connected to both sides of the mounting seat 4, a pair of the rotating shafts 31 are rotatably arranged on the bracket 2, one of the rotating shafts 31 passes through the bracket 2 and is connected to a limited rotating plate 32, a positioning pin 33 is passed through the limiting rotating plate 32, and two positioning holes 34 are provided on the bracket 2, the two positioning holes 34 are symmetrically arranged with the axis center of the rotating shaft 31 as the midpoint, and the positioning pin 33 matches the two positioning holes 34.

[0015] The above-mentioned mounting seat 4 is generally U-shaped, and a clamping piece 7 is provided at both ends of one side of the mounting seat 4. The clamping piece 7 includes a threaded through hole 71 opened on the side of the mounting seat, and a clamping bolt 72 is passed through the threaded through hole 71. The end of the clamping bolt 72 located inside the mounting seat 4 is provided with a rubber pressure plate 73.

[0016] The above-mentioned translation assembly 5 includes a slide rail 52, a slide plate 51 and an electric push rod 53. The slide rail 52 is arranged on the base plate 1, one end of the slide rail 52 extends toward the mounting seat 4, and the other end of the slide rail 52 is provided with the electric push rod 53. The slide plate 51 is slidably arranged on the slide rail 52, and the output end of the electric push rod 53 is fixedly connected to the slide plate 52.

[0017] The grinding assembly 6 includes a grinding disc 61 and a motor 62 . The motor 62 is disposed on the slide plate 51 , and the grinding disc 61 is disposed on the output shaft of the motor 62 .

[0018] The advantages and beneficial effects of the utility model are as follows: it provides a trimming device for plastic valve production, which can clamp and fix the plastic valve through the mounting seat 4, and then drive the grinding disc 61 of the grinding assembly 6 to approach or move away from the mounting seat 4 through the translation assembly 5, so as to complete the grinding of one end of the plastic valve. When the grinding and trimming of this end is completed, it is only necessary to flip and position the plastic valve and the mounting seat 4 at the same time through the flipping assembly 3, and then the grinding and trimming of the other end of the plastic valve can be continued. There is no need to repeatedly clamp and fix the plastic valve, which reduces the workload of workers and improves the trimming efficiency of the valve.

[0019] When working, first place the plastic valve in the mounting seat 4, and then rotate the clamping bolt 72 to drive the rubber pressure plate 73 to move, so that the two clamping parts 7 complete the fixing of the plastic valve. After the plastic valve is installed and fixed, start the motor 62 and the electric push rod 53. The motor 62 can drive the grinding disc 61 to rotate at high speed, and the electric push rod 53 can drive the rotating grinding disc 61 to approach the plastic valve. The grinding disc 61 contacts one end of the plastic valve, and the grinding and trimming work of one end of the plastic valve can be realized;

[0020] When one end of the plastic valve is polished, the electric push rod 53 drives the polishing disc 61 away from the plastic valve, pulls out the locating pin 33 on the limit rotating plate 32, separates the locating pin 33 from a locating hole 34 on the bracket 2, and then rotates the limit rotating plate 32. The limit rotating plate 32 drives the mounting seat 4 and the plastic valve to flip through the rotating shaft 31. When the locating pin 33 on the rotation limit 32 is aligned with another locating hole 34 on the bracket 2, the mounting seat 4 and the plastic valve are synchronously flipped 180 degrees, so that the other end of the plastic valve is facing the polishing disc 61 of the polishing assembly 6, and then the locating pin 33 is inserted into the relatively aligned locating hole 34 to complete the positioning of the mounting seat 4 and the plastic valve. The other end of the plastic valve can be continued to be polished and trimmed by the polishing disc 61. In this way, there is no need to repeatedly clamp and fix the plastic valve, which reduces the clamping work steps and improves the trimming efficiency of the valve.

[0021] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
