Description

Technical Field

[0001] This utility model relates to the field of valve body casting grinding technology, specifically a valve body casting grinding device. Background Technology

[0002] In the valve manufacturing industry, after the valve body castings (such as cast iron, cast steel, and stainless steel valve bodies) are cast, their outer surfaces will inevitably have defects such as risers, flash, and burrs. The surface roughness of key parts such as flange edges and valve body circumference directly affects the valve's assembly sealing performance and service life, so they must be polished.

[0003] Existing mechanical devices mostly use clamping and fixing from the outer wall of the valve body. The clamping mechanism can easily block the area to be polished, requiring multiple disassembly and adjustment of the clamping position to complete the full polishing. Furthermore, for valve bodies of different lengths and diameters, appropriate clamping fixtures need to be replaced, resulting in poor versatility.

[0004] Therefore, it is necessary to invent a valve body casting grinding device. Utility Model Content

[0005] The purpose of this invention is to provide a valve body casting grinding device to solve the problems mentioned in the background art.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The motor drives a three-drive bevel gear set and a threaded rod to simultaneously open and clamp the clamping ring from the inner wall of the valve body. The clamping ring is fixed by friction and support force. On the one hand, it completely avoids the grinding area of ​​the outer wall of the valve body, and the grinding can be completed without disassembly, reducing the time between processes. On the other hand, the clamping ring can adapt to the inner cavity of valve bodies of different diameters through the back movement of the sliding plate, and there is no need to change the tooling. At the same time, the inner wall clamping method can avoid the pressure and scratches caused by the outer wall clamping to the surface of the valve body, improve the clamping stability and the versatility of the device, and adapt to the batch grinding needs of valve bodies of various specifications. 2. This solution uses two electric telescopic rods to achieve multi-dimensional electric adjustment of the grinding wheel in both horizontal (lateral) and vertical (pressure) directions. Combined with the synchronous rotation of the valve body driven by motor two, the grinding wheel can continuously grind multiple areas of the valve body in the circumferential and longitudinal directions. The annular area can be processed without manually adjusting the position of the valve body or the grinding wheel. At the same time, the grinding pressure can be controlled in real time by finely adjusting the extension of electric telescopic rod two, effectively avoiding over-cutting or incomplete grinding.

[0022] Furthermore, a column 284 is fixedly provided on one side of the L-shaped rod 283, and the column 284 is fixedly connected to the clamping ring 285.

[0023] Furthermore, a second motor 21 is fixedly mounted on one side of the fixed plate 12. The output shaft of the second motor 21 passes through the fixed plate 12 and is fixedly connected to the rotating plate 22 to facilitate the rotation of the rotating plate 22.

[0026] Furthermore, an electric telescopic rod 16 is fixedly provided on the top of the horizontal plate 15. The telescopic end of the electric telescopic rod 16 passes through the horizontal plate 15 and is fixedly connected to the rectangular frame 17.

[0027] Furthermore, an electric telescopic rod 31 is fixedly provided on the other side of the vertical plate 11. An L-shaped rod 311 is fixedly provided at the telescopic end of the electric telescopic rod 31. A sliding groove 111 is provided on one side of the vertical plate 11. The L-shaped rod 311 passes through the sliding groove 111 and is fixedly connected to the back plate 32, which facilitates the back plate 32 to move back and forth.

[0028] Working principle: When this solution is in use, the electric telescopic rod 31 is activated, and its telescopic end drives the L-shaped rod 311 to slide along the slide groove 111 of the vertical plate 11, pushing the back plate 32 to move horizontally on the bottom plate 1. The distance between the fixed plate 12 and the back plate 32 is adjusted according to the length of the valve body casting, so that the clamping rings 285 of the two connecting boxes 24 can be inserted into the inner cavities at both ends of the valve body, in preparation for clamping the inner wall. Start motor 25, which in turn drives bevel gear 26 to rotate, which in turn drives bevel gear 28 and bevel gear 29 to mesh, which in turn drives threaded rod 281 and threaded rod 292 to rotate, which further drives slide plate 282 and slide plate 293 to move in opposite directions, which will then spread out in the direction of the "valve body cavity wall". Using the friction and support force between the clamping ring 285 and the valve body cavity wall, the two ends of the valve body are firmly fixed from the inside. Then, start the electric telescopic rod 16, which in turn moves the rectangular frame 17 downward, and then moves the grinding wheel 19 downward until the grinding wheel 19 contacts the outer surface of the valve body to be ground (such as the flange edge, the burrs on the side of the valve body, etc.) and reaches the appropriate grinding pressure. Then, start the motor 18, whose output shaft drives the grinding wheel 19 to rotate at high speed, which facilitates the grinding operation on the clamped valve body. At the same time, start the motor 21, which drives the rotating plate 22 to rotate. Since the rotating plate 22 is fixedly connected to the connecting box 24, and the connecting box 24 is clamped to the valve body by the clamping ring 285, the clamped valve body rotates synchronously, which facilitates the continuous and uniform grinding of the outer wall of the valve body by the grinding wheel 19. The processing of the annular area can be completed without manually adjusting the position of the valve body. If grinding is required at different lateral positions of the valve body, the electric telescopic rod 13 can be activated. Its telescopic end pushes the block 14 to drive the horizontal plate 15 to slide horizontally along the slide groove 112 of the vertical plate 11, thereby driving the grinding wheel 19 to move along the length of the valve body. During the grinding process, the pressure of the grinding wheel 19 on the valve body can be adjusted in real time by finely adjusting the telescopic amount of the electric telescopic rod 16, so as to ensure the grinding effect while avoiding excessive cutting and damage to the surface of the valve body.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
