[0028] Reference Figure 1 and Figure 2 The present application grinds the valve body fixed by the clamping assembly 2 by setting a clamping assembly 2 and a grinding assembly 3, wherein the grinding assembly 3 drives the grinding roller to perform grinding operation by vertically rotating on the inner wall of the box body 1. The grinding assembly 3 mainly includes a first grinding roller 340 and a second grinding roller 350 on both sides of the box body 1. There are two first grinding rollers 340, which grind the outer wall or the inner wall of the end synchronously. The second grinding roller 350 is mainly used for grinding the surface of the end. The rotating disk 1 30 and the rotating disk 2 31 respectively drive the first grinding roller 340 and the second grinding roller 350 to perform grinding and deburring operations.

[0029] It should be noted that after the burrs on one end are removed under the first grinding roller 340, the clamping assembly 2 rotates the entire valve body horizontally to transfer the end to the corresponding position of the second grinding roller 350 for grinding and removing the end surface. At the same time, the first grinding roller 340 and the second grinding roller 350 perform grinding operations synchronously, saving time and improving work efficiency.

[0030] In order to facilitate the adjustment of the grinding distance between the first grinding roller 340 and the end of the valve body, a rotating groove 11 is provided on the inner wall of the box body 1, and the rotating disk 30 is located in the rotating groove 11. The side center of the rotating plate is connected to the output end of the telescopic rod 32, and the side of the rotating disk 30 away from the first rotating motor 36 is provided with a telescopic rod 32 and the first grinding roller 340.

[0031] Reference Figure 3 Under the action of the first rotating motor, the rotating disk 30 is driven to rotate vertically inside the rotating groove to expand the grinding range of the first grinding roller 340. At the same time, the telescopic rod 32 is driven by an external controller to adjust the distance between the first grinding roller 340 and the end face of the valve body, so that the two first grinding rollers 340 are simultaneously located in the axial direction of the inner wall or the outside, so that the first grinding roller 340 can adapt to the grinding of valve body ends of various lengths.

[0032] In some preferred embodiments, a double push rod motor 33 is provided between the telescopic rod 32 and the first grinding roller 340 , and a first drive motor 34 is provided at the top and bottom ends of the double push rod motor 33 , respectively, and the output end of the first drive motor 34 is connected to the first grinding roller 340 .

[0033] Specifically, the double push rod motor 33 is set so that the telescopic part inside it drives the first drive motor 34 to adjust the distance, so that the distance between the two first grinding rollers 340 is respectively adapted to the inner wall and outer wall of the valve body end, and the two first grinding rollers 340 are synchronously ground around the inner wall or the outer wall through the rotation of the rotating disk 1 30, and the grinding is thorough.

[0034] In some preferred embodiments, the telescopic rod 1 32 is located on the horizontal central axis of the rotating disk 1 30. The installation position of the telescopic rod 1 32 here is mainly achieved by the double push rod motor 33, which can make the first grinding roller 340 and the second grinding roller 350 uniformly and synchronously grind the inner wall or the outer wall.

[0035] In some preferred embodiments, the inner wall of the box body 1 opposite to the rotating groove 11 is provided with a rotating groove 2 12, the rotating disc 2 31 is located in the rotating groove 2 12, the rotating groove 2 12 is connected to the output end of the second rotating motor 37, and the side of the rotating disc 2 31 away from the second rotating motor 37 is provided with a telescopic rod 2 38 and a second grinding roller 350. A second driving motor 35 is provided between the telescopic rod 2 38 and the second grinding roller 350, and the installation position of the telescopic rod 2 38 is adjacent to the outer peripheral surface of the rotating disc 2 31.

[0036] Specifically, the rotating disk 2 31 is located in the rotating groove 2 12, and the entire rotating disk is rotated vertically under the action of the second rotating motor 37. At the same time, the grinding operation is performed after the second grinding roller 350 and the end face are adjusted to match the grinding distance under the action of the telescopic rod 2 38. Since the end of the valve body is an annular structure, the position of the telescopic rod in the rotating disk 2 31 is adjacent to the outer peripheral surface, so that the second grinding roller 350 is driven to grind its end face during the rotation of the rotating disk 2 31, and its overall rotation trajectory is adapted to the annular end.

[0037] Example 2

[0038] Embodiment 2 of the present utility model is implemented on the basis of embodiment 1, the clamping assembly 2 comprises a U-shaped seat 21 and a third rotary motor 20, the output end of the third rotary motor 20 passes through the bottom of the box 1 and is connected to the bottom center of the U-shaped seat 21, the inner wall of the U-shaped seat 21 is symmetrically provided with a telescopic rod 3 22, and the output end of the telescopic rod 3 22 is connected to a clamping block 27. The end of the clamping block 27 away from the telescopic rod 3 22 is provided with a buffer pad 23.

[0039] Specifically, the U-shaped seat 21 forms the basis of the clamping assembly 2, and the clamping block 27 is used to fix and clamp the transversely placed valve body. At the same time, the buffer pad 23 provided on the clamping block 27 can prevent the metal clamping block 27 from damaging the outer periphery of the valve body and shortening the service life of the clamping block 27. The telescopic rod 22 drives the clamping block 27 to clamp and fix valve bodies of different diameters, thereby improving the utilization rate of the device.

[0040] And under the action of the third rotating motor 20, when the end direction needs to be changed, it is only necessary to turn on the external controller to make the third rotating motor 20 work, so that the entire U-shaped seat 21 rotates horizontally. During the rotation, the clamping block 27 always maintains a firm clamp on the valve body until the port rotates to the position of the first grinding roller 340 and the second grinding roller 350 and stops rotating, thereby performing the corresponding grinding operation.

[0041] In some preferred embodiments, a sliding groove 210 is provided at the bottom of the U-shaped seat 21, and both sides of the sliding groove 210 are connected to a sliding block 25 via springs 26 respectively. A fixing column 24 is provided at the top of the sliding block 25, and a curved surface is provided at the top of the fixing column 24.

[0042] Reference Figure 4 At the same time, the sliding groove 210 is set at the bottom of the U-shaped seat 21, and the sliding block 25 moves under the elastic action of the spring 26, so that the top of the fixed column 24 abuts against the outer peripheral surface of the bottom of the valve body, ensuring that the bottom of the valve body is supported and enhancing the stability of the entire valve body. At the same time, the top of the fixed column 24 is provided with an arc surface to better support the bottom of the valve body.

[0043] Example 3

[0044] This embodiment 3 is implemented on the basis of embodiment 1, and also includes a dust suction component 4, which includes a dust suction hopper 42 located at the bottom of the box body 1 and connected to the collection box 41 through a pipe. The collection box 41 is connected to the vacuum cleaner 40, and a filter 43 is provided in the dust suction hopper 42.

[0045] The dust collection component 4 is mainly driven by the vacuum cleaner 40. The dust and debris generated during grinding are filtered through the filter screen 43 through the dust collection hopper 42 and then transmitted to the inside of the collection box 41 through the pipeline, which is convenient for later cleaning. At the same time, it avoids the harm of the dust and debris in the cleaning box 1 to the human respiratory system, thereby improving the working environment.

[0046] The working principle of the utility model is as follows: when in use, the valve body is placed horizontally between the two clamping blocks 27, the telescopic rod three 22 is started, and the spacing between the two fixed columns 24 is manually adjusted under the action of the spring 26, so that both sides and the bottom of the valve body are supported and fixed, thereby adjusting the telescopic rod one 32 and the telescopic rod two 38, so that the first grinding roller 340 and the second grinding roller 350 are respectively in contact with the two ends of the valve body, and the double push rod motor 33 is started, so that the two first grinding rollers 340 are simultaneously located on the inner wall or the outer wall of the end of the valve body and contact, and the first drive motor 34 and the second drive motor 35 are started, so that the first grinding roller 340 and the second grinding roller 350 are respectively polished to the inner wall / outer wall and the end face of the end, and during polishing, the first rotating motor 36 and the second rotating motor 37 are mainly used to drive the rotating disk one 30 and the rotating disk two 31 to rotate, so that the first grinding roller 340 and the second grinding roller 350 make a circular motion around the end, and after the burrs are removed, the third rotating motor 20 is started, and the position of the end is adjusted, and then the polishing process is continued. During the grinding process, the dust collector is always turned on to collect dust and debris. The grinding efficiency is high and the effect is good. There is no need for manual clamping and grinding. The clamping stability is high, and the inner and outer walls and end faces of the end are evenly ground, which improves work efficiency.

[0047] The above is only a preferred embodiment of the utility model and does not limit the utility model in any form. According to the technical essence of the utility model, within the spirit and principles of the utility model, any simple modification, equivalent replacement and improvement made to the above embodiment still falls within the protection scope of the technical solution of the utility model.
