Description

Technical Field

[0001] This utility model relates to the technical field of valve seat grinding equipment, specifically to a valve seat grinding mechanism for the production of plastic products. Background Technology

[0002] The valve seat is one of the important detachable components of a valve. It supports the valve core and also plays a sealing role. Generally, the diameter of the valve seat is the maximum flow diameter of the valve. The valve seat is usually a hollow cylindrical structure. In order to ensure the flow of the valve, the surface of the valve seat must be smooth, so it needs to be polished. With the development of technology, there are now many materials used to make valve seats to meet different usage requirements.

[0003] The main problem with polishing nowadays is the fixing, because the fixing requirements for valve seats of different shapes and sizes are different, and the external clamping method will also affect the surface polishing effect. Therefore, a valve seat polishing mechanism for plastic products is proposed again. Utility Model Content

[0004] The technical problem this utility model aims to solve is that the main issues in current polishing processes are focused on fixing, because the fixing requirements for valve seats of different sizes are different, and the external clamping method can also affect the surface polishing effect. This utility model provides a valve seat polishing mechanism for plastic product manufacturing, which can adjust the direction of the valve seat as needed, so as to ensure that the valve seat and the polishing wheel are fully in contact, ensuring the polishing effect, and positioning the valve seat from the inside out to avoid affecting the surface treatment effect.

[0005] The technical solution adopted by this utility model to solve the technical problem is: a valve seat grinding mechanism for producing plastic products, including a processing table, a through hole is opened through the top of the processing table, a vertical plate is fixedly connected to the top of the processing table and near the edge of the through hole, a No. 1 motor is detachably embedded in the middle of the side wall of the vertical plate near the through hole, a fixed column is set above the middle of the through hole, the fixed column is a cylindrical structure, and an anti-slip pad is fixedly connected to the outer wall of the fixed column near the top.

[0006] As a preferred technical solution of this utility model, the fixing column is composed of four arc-shaped plates. A cross plate is provided in the middle of one end of the fixing column. A rotating shaft is rotatably connected to one end of the cross plate and near the edge. A follower block is fixedly connected to one side of the rotating shaft. The follower block is fixedly connected to the inner wall of one end of the four arc-shaped plates through its end away from the rotating shaft.

[0007] As a preferred technical solution of this utility model, a stud is provided in the middle of the fixed column, one end of the stud is rotatably connected to the middle of one side wall of the cross plate, a sleeve is threaded on the stud, and four top support plates are evenly rotatably connected to one end edge of the sleeve. The four top support plates are rotatably connected to the inner wall of the four arc plates away from the cross plate through their ends away from the sleeve.

[0008] As a preferred technical solution of this utility model, a connecting plate is fixedly connected to the side of the cross plate away from the stud. A second motor is detachably connected to the middle of the connecting plate by screws. One end of the second motor passes through the cross plate and is detachably connected to one end of the stud. A connecting arm is fixedly connected to one side wall of the cross plate. One end of the connecting arm is detachably connected to the output end of the first motor by screws. A limiting post is fixedly connected to the side wall of the cross plate above the stud. The limiting post is inserted into the side wall of the sleeve post.

[0009] As a preferred technical solution of this utility model, the upright plate has an L-shaped structure, and the side wall of the upright plate at the bottom of the horizontal plate and opposite to the fixed column is detachably connected to a telescopic rod by screws. The output end of the telescopic rod is detachably connected to a grinding wheel by a rotary driver.

[0010] As a preferred technical solution of this utility model, a lower enclosure plate is fixedly connected to the bottom of the processing table and the side wall opposite to the through hole.

[0011] This utility model has the following advantages: The valve seat to be processed is placed on the fixed column, and then the second motor is started to drive the stud to rotate. The sleeve is driven to move along the stud through the threaded connection. As the sleeve moves, it pushes the top support plate forward. As the force increases, the top support plate expands outward, thereby opening one end of the four arc plates. The force generated by this process fixes the valve seat. In addition, because the outer wall of the fixed column is fixed with an anti-slip pad, it can avoid wear on the valve seat and increase friction to improve the stability of the valve seat.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3 This utility model discloses a valve seat grinding mechanism for producing plastic products, including a processing table 1. A through hole 2 is provided on the top of the processing table 1. A vertical plate 3 is fixedly connected to the top of the processing table 1 and near the edge of the through hole 2. A No. 1 motor 6 is detachably embedded in the middle of the side wall of the vertical plate 3 near the through hole 2. A fixing column 8 is provided above the middle of the through hole 2. The fixing column 8 is a cylindrical structure. An anti-slip pad 10 is fixedly connected to the outer wall of the fixing column 8 near the top.

[0018] The fixing post 8 consists of four arc-shaped plates. A cross plate 13 is set in the middle of one end of the fixing post 8. A rotating shaft 12 is rotatably connected to one end of the cross plate 13 near its edge. A follower block 11 is fixedly connected to one side of the rotating shaft 12. The follower block 11 is fixedly connected to the inner wall of one end of the four arc-shaped plates through its end away from the rotating shaft 12. A stud 16 is set in the middle of the fixing post 8. One end of the stud 16 is rotatably connected to the middle of one side wall of the cross plate 13. A sleeve post 18 is threaded onto the stud 16. Four top support plates 19 are evenly rotatably connected to one end of the sleeve post 18 near its edge. The four top support plates 19 are fixedly connected to the inner wall of one end of the four arc-shaped plates through their ends away from the sleeve post 18. One end is rotatably connected to the inner wall of the four arc-shaped plates away from the cross plate 13. A connecting plate 14 is fixedly connected to the side of the cross plate 13 away from the stud 16. A second motor 15 is detachably connected to the middle of the connecting plate 14 by screws. The end of the second motor 15 passes through the cross plate 13 and is detachably connected to one end of the stud 16. A connecting arm 7 is fixedly connected to one side wall of the cross plate 13. One end of the connecting arm 7 is detachably connected to the output end of the first motor 6 by screws. A limiting post 17 is fixedly connected to the side wall of the cross plate 13 above the stud 16. The limiting post 17 is inserted into the side wall of the sleeve post 18.

[0019] The technical advantages of this solution are as follows: Because the fixed column 8 is composed of four independent arc-shaped plates, and the four arc-shaped plates are connected to the follower block 11 that can rotate along the rotating shaft 12, the four arc-shaped plates can be expanded and unfolded as needed. In this way, the valve seat is fitted onto the fixed column 8, and then the stud 16 is driven to rotate. Through the threaded connection, the sleeve column 18 is driven to move. In this way, the four arc-shaped plates can be pushed open by the top support plate 19, thereby pressing the anti-slip pad 10 against the inner wall of the valve seat, forming an external support positioning effect. This achieves stable positioning without affecting the surface wall processing effect. Moreover, it provides support positioning for the inner wall, making it applicable to valve seats of different sizes and improving the practicality of the application. Because the connecting arm 7 is connected to the first motor 6, it can drive the fixed column 8 and the valve seat to rotate and adjust, thereby improving the processing efficiency.

[0020] The upright plate 3 has an L-shaped structure. The bottom of the horizontal plate of the upright plate 3 and the side wall opposite to the fixed column 8 are detachably connected to the telescopic rod 4 by screws. The output end of the telescopic rod 4 is detachably connected to the grinding wheel 5 by a rotary driver. The bottom of the processing table 1 and the side wall opposite to the through hole 2 are fixedly connected to the lower enclosure plate 9. The lower enclosure plate 9 has a hollow structure inside and a receiving box 20 is inserted. The top opening of the receiving box 20 corresponds to the through hole 2.

[0021] The technical effect of this solution is as follows: the grinding wheel 5 is driven to rotate, thereby grinding the valve seat. The grinding debris generated by the through hole 2 can fall into the receiving box 20 through the through hole 2, thereby collecting the debris and avoiding the accumulation of debris that would affect the grinding effect.

[0022] Specifically, when using this utility model, the valve seat to be processed is first placed on the top of the fixed column 8, and then the second motor 15 is started to drive the stud 16 to rotate. The sleeve column 18 is then driven to move through the threaded connection. As the sleeve column 18 moves, it will apply pressure to the top support plate 19. Since the two ends of the top support plate 19 are rotatably connected, the top support plate 19 will gradually rotate from an inclined state to an upright state under the thrust, thereby driving the arc plate to unfold and support and fix the inner wall of the valve seat. After fixing, the grinding wheel 5 is driven to rotate to grind the valve seat. The tilt direction of the valve seat can be adjusted by the first motor 6 to achieve grinding at different angles.

[0023] Based on the above, a guide rail cylinder can be connected to the vertical plate 3, and the first motor 6 can be connected to the guide rail cylinder to achieve the effect of lateral movement. At the same time, a driver can be connected to the rear end of the second motor 15 to drive the fixed column 8 to rotate. In this way, the valve seat can be fully adjusted, further increasing the flexibility of the application.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
