[0037] Embodiment 1 Referring to Figures 1 to 12 , this is the first embodiment of the present invention, which provides a method for grinding the surface of a ball valve body.

[0038] First, the valve body 105 is adsorbed and clamped, and then it is ground by relying on the first grinding rod 203f or the second grinding rod 204d; After adsorbing and clamping the valve body 105, the inner wall of the valve body 105 can be polished using the first polishing rod 203f or the second polishing rod 204d according to the shape of its inner wall, and then the waste chips generated during polishing can be absorbed by setting the suction pump 313; First, place the valve body 105 on the blanking plate 103, adjust the distance between the baffles 104 through the electric cylinder 106 to preliminarily limit the valve body 105 with the baffles 104. Then, the first electric push rod 107e drives the transmission rod 201 to extend into the valve body 105. Through the movement of the transmission rod 201, the clamping ring 202e drives the suction cup 202f to adsorb on the inner wall of the valve body 105. Start the first motor 202b to make the clamping ring 202e rotate and firmly fix the valve body 105 on the transmission rod 201; Polishing selection: According to the shape of the inner wall of the valve body 105, select the appropriate first polishing assembly 203 or second polishing assembly 204 for polishing. If the inner wall of the valve body 105 is annular or arc-shaped, start the second electric push rod 203c to make the first polishing rod 203f of the first polishing assembly 203 fit the inner wall for polishing; if the side of the inner wall of the valve body 105 is in a vertical state, start the third electric push rod 204b to make the second polishing rod 204d of the second polishing assembly 204 extend for polishing.

[0039] Embodiment 2 Refer to Figures 1 to 9 , which is the second embodiment of the present invention, and provides a support mechanism 100.

[0040] Support mechanism 100, which includes a support plate 101. At both ends of the top of the support plate 101, support blocks 102 are provided. At the top of the support blocks 102, a blanking plate 103 is provided. At both ends of the top of the blanking plate 103, baffles 104 are provided. A valve body 105 is provided on the top of the blanking plate 103 and is located inside the baffles 104. Electric cylinders 106 for transmission are provided on both sides of the baffles 104. The opposite sides of the electric cylinders 106 are fixedly connected to the top of the blanking plate 103. An adjustment assembly 107 is provided on the top of the support plate 101; the adjustment assembly 107 includes fixed blocks 107a provided at both ends of the top of the support plate 101. A screw rod 107b is provided on the opposite sides of the fixed blocks 107a. A drive motor 107c for transmission is provided on the front side of the screw rod 107b. The rear side of the drive motor 107c is fixedly connected to the front side of the fixed block 107a. Two groups of adjustment blocks 107d are drivingly connected to the surface of the screw rod 107b. First electric push rods 107e are provided on the tops of the adjustment blocks 107d. The outer sides of the adjustment blocks 107d are slidably connected to the inner sides of the limiting grooves 107f. The limiting grooves 107f are opened on the top of the support plate 101; two placement grooves 303 are opened on the top of the baffle 104. Lifting grooves 304 are opened on the surfaces of the two placement grooves 303. A fourth electric push rod 305 is provided on the surface of the lifting groove 304. A telescopic plate 306 is drivingly connected to the top of the fourth electric push rod 305. The telescopic plate 306 is used to block the valve body 105; A number of connecting blocks 307 are provided on the inner sides of the rotating plates 207. Air suction pipes 308 are communicated inside the number of connecting blocks 307. The air suction pipes 308 are all communicated with an air suction ring 309. The front side of the air suction ring 309 is fixedly connected to the rear side of the fixed ring 202a through a connecting column 310. The connecting column 310 is provided on the opposite sides of the air suction ring 309 and the fixed ring 202a; A first air suction pipe 311 is communicated with the bottom of the air suction ring 309. A second air suction pipe 312 is communicated with the bottom of the first air suction pipe 311. The left side of the second air suction pipe 312 is communicated with the suction end of an air suction pump 313. The discharge end of the air suction pump 313 is communicated with a collection box 314. The rear sides of the collection box 314 and the air suction pump 313 are fixedly connected to the front side of the blanking plate 103.

[0041] Specifically, during actual operation, first place the valve body 105 on the blanking plate 103, between the two baffles 104. Start the electric cylinder 106, adjust the distance between the baffles 104 according to the size of the valve body 105, so that the baffles 104 fit against both sides of the valve body 105 to achieve preliminary fixation of the valve body 105. Then, start the drive motor 107c. The drive motor 107c drives the screw 107b to rotate, causing the adjusting block 107d to move on the screw 107b, thereby adjusting the lateral position of the first electric push rod 107e and the subsequent grinding mechanism 200. At the same time, according to the height of the valve body 105, control the telescopic movement of the first electric push rod 107e to adjust its longitudinal height, so that the transmission rod 201 can accurately extend into the valve body 105. During the grinding process, start the suction pump 313, and use the waste chip collection system composed of the communication block 307, the suction ring 309, the suction pipe 308, the first suction pipe 311, and the second suction pipe 312 to suck the waste chips generated by grinding into the collection box 314.

[0042] Furthermore, when placing the valve body 105, the operator should ensure that the valve body 105 is placed stably on the blanking plate 103 and is at the center position between the two baffles 104. After starting the electric cylinder 106, the electric cylinder 106 will accurately adjust the distance between the baffles 104 according to the preset program based on the size of the valve body 105. For example, for a large-sized valve body 105, the electric cylinder 106 slowly shortens to increase the distance between the baffles 104 until the baffles 104 fit against both sides of the valve body 105; for a small-sized valve body 105, the electric cylinder 106 contracts to decrease the distance between the baffles 104. When the drive motor 107c drives the screw 107b to rotate, by precisely controlling the rotation speed and direction of the motor, accurate movement of the adjusting block 107d can be achieved. The speed and distance of the adjusting block 107d moving on the screw 107b will be adjusted according to the position of the valve body 105 and the grinding requirements. During the telescopic movement of the first electric push rod 107e, according to the pre-measured height of the valve body 105, the telescopic amount is accurately controlled to ensure that the transmission rod 201 can accurately extend into the appropriate position inside the valve body 105. When the telescopic plate 306 needs to be raised or lowered, the fourth electric push rod 305 will rise or fall at the set speed and stroke, causing the telescopic plate 306 to rise or fall smoothly, playing a reliable role in blocking or releasing the block of the valve body 105. After the suction pump 313 is started, a stable negative pressure will be formed in the communication block 307 and the suction ring 309, and the waste chips will be quickly sucked into the suction pipe 308, passing through the first suction pipe 311 and the second suction pipe 312, and finally efficiently entering the collection box 314.

[0043] It should be noted that the first suction pipe 311 is a flexible pipe, and the second suction pipe 312 is a rigid pipe; through the setting of the flexible pipe and the rigid pipe, it can better adapt to the height adjustment of the clamping ring 202e; the thread on the surface of the screw 107b is set as a double-thread.

A suction cup 202f is arranged at the rear side of the clamping ring 202e, and the suction cup 202f is used for fixing the valve body 105. The first grinding assembly 203 includes an extension groove 203a opened on the surface of the transmission rod 201. A clamping block 203b is arranged on the surface of the extension groove 203a. Second electric push rods 203c are arranged on both the upper and lower sides of the clamping block 203b. The output ends of the second electric push rods 203c are fixedly connected with extension plates 203d. A plurality of compression springs 203e are arranged on the tops of the extension plates 203d. A plurality of first grinding rods 203f are arranged on the tops of the plurality of compression springs 203e. The second grinding assembly 204 includes a fixing groove 204a opened inside the transmission rod 201. A third electric push rod 204b is arranged on the surface of the fixing groove 204a. The output ends of the third electric push rods 204b are drivingly connected with pull rods 204c. Second grinding rods 204d are arranged on the surfaces of the pull rods 204c. A pulling groove 205 is opened on the surface of the extension groove 203a. A first pulling spring 206 is arranged on the surface of the pulling groove 205. The right side of the first pulling spring 206 is pullingly connected with the left side of the first grinding rod 203f. The inner wall of the clamping ring 202e is rotationally connected with a rotating plate 207 through a rotating groove 207a. The rotating groove 207a is opened on the inner wall of the clamping ring 202e. A travel rod 208 is arranged on the inner side of the rotating plate 207. The surface of the travel rod 208 is slidably connected with the surface of a travel groove 209. The travel groove 209 is opened on the surface of the transmission rod 201. A second pulling spring 210 is arranged on the surface of the travel groove 209. The left side of the second pulling spring 210 is fixedly connected with an extended grinding rod 211. The outer side of the extended grinding rod 211 is fixedly connected with the inner side of the second grinding rod 204d. A pulling groove 212 is opened on the inner wall of the pull rod 204c. A pulling cross bar 213 is slidably connected to the surface of the pulling groove 212. The bottom of the pulling cross bar 213 is fixedly connected with the outer side of the second grinding rod 204d. A transverse groove 301 is opened on the outer side of the transmission rod 201. A transverse block 302 is slidably connected to the surface of the transverse groove 301. The top of the transverse block 302 is fixedly connected with the inner side of the rotating plate 207. Specifically, after the transmission rod 201 extends into the valve body 105 driven by the first electric push rod 107e, the first motor 202b is started. The first motor 202b drives the gear 202c to rotate, and the gear 202c drives the toothed disc 202d to rotate, thereby causing the clamping ring 202e to rotate. When the clamping ring 202e moves to a suitable position, the suction cup 202f adsorbs on the inner wall of the valve body 105, firmly fixing the valve body 105, and driving the clamping ring 202e to rotate through the operation of the first motor 202b. If the inner wall of the valve body 105 is annular or arc-shaped, the second electric push rod 203c is started to push the extension plate 203d to extend. The extension plate 203d drives the first grinding rod 203f to approach the inner wall of the valve body 105. Utilizing the elasticity of the compression spring 203e, the first grinding rod 203f adaptively fits the inner wall for grinding. If the side surface of the inner wall of the valve body 105 is in a vertical state, the third electric push rod 204b is started, so that the pull rod 204c drives the second grinding rod 204d to extend and contact the inner wall of the valve body 105. As the first motor 202b drives the valve body 105 to rotate, the second grinding rod 204d grinds the cylindrical inner wall.

[0046] Furthermore, before the transmission rod 201 extends into the valve body 105, it is necessary to ensure that the center line of the transmission rod 201 coincides with the center line of the valve body 105 as much as possible to improve the grinding accuracy. After the first motor 202b is started, it will drive the gear 202c to rotate at a stable speed. The precise meshing of the gear 202c and the toothed disc 202d ensures that the clamping ring 202e can rotate smoothly. When the transmission rod 201 moves to a suitable position, the suction cup 202f will quickly generate suction and firmly adsorb on the inner wall of the valve body 105. For the grinding of the annular or arc-shaped inner wall, by controlling the telescopic amount of the second electric push rod 203c, the extension plate 203d drives the first grinding rod 203f to slowly approach the inner wall. The compression spring 203e will adjust the compression amount in real time according to the unevenness of the inner wall to ensure that the first grinding rod 203f always maintains a good contact pressure with the inner wall. The first pulling spring 206 will further enhance the stability of the first grinding rod 203f and prevent it from shaking during the grinding process. When grinding the side surface of the inner wall of the valve body 105 in a vertical state, when starting the third electric push rod 204b, control the extension length of the pull rod 204c so that the second grinding rod 204d accurately contacts the inner wall. The pull rod cross bar 213 slides in the pull slot 212 to ensure that the second grinding rod 204d remains stable during the telescopic process. The cooperation of the rotating plate 207, the stroke rod 208, the stroke slot 209, the second pulling spring 210 and the extended grinding rod 211 will enable the second grinding rod 204d to better grind along with the inner wall of the valve body 105. When adapting to valve bodies 105 with different diameters, the movement of the cross block 302 in the cross slot 301 is smooth and stable. The return spring 302a will quickly reset components such as the suction cup 202f, the clamping ring 202e and the motor to the initial position after the grinding is completed.

[0047] It should be noted that the extended polishing rod 211 is configured to be retractable; the suction cup 202f is electrically controlled to make the adsorption more stable.

[0048] The remaining structure is the same as that of Example 2.

The electric cylinder 106 is installed on both sides of the baffle 104, and the opposite side thereof is fixedly connected to the top of the blanking plate 103. When it is necessary to grind valve bodies 105 of different sizes, the electric cylinder 106 can be extended and retracted according to the size of the valve body 105, thereby adjusting the distance between the two baffles 104, so that the baffles 104 can fit both sides of the valve body 105, and achieve a stable clamping of the valve body 105. For example, for a valve body 105 of a larger size, the electric cylinder 106 is shortened to increase the distance between the baffles 104; for a valve body 105 of a smaller size, the electric cylinder 106 is extended to reduce the distance between the baffles 104; The main function of the adjustment component 107 is to adjust the position of the grinding mechanism 200 to meet the grinding requirements of different valve bodies 105. It consists of a fixed block 107a, a screw rod 107b, a drive motor 107c, an adjustment block 107d and a first electric push rod 107e. The fixing blocks 107a are arranged at both ends of the top of the support plate 101, and are used to support the screw rod 107b. The screw rod 107b is installed on the opposite side of the two fixing blocks 107a, and the front side thereof is connected with a driving motor 107c. When the driving motor 107c is started, the screw rod 107b is driven to rotate. Since the surface of the screw rod 107b is connected with an adjusting block 107d, the rotation of the screw rod 107b causes the adjusting block 107d to make relative or opposite motion on the screw rod 107b. By controlling the forward and reverse rotation of the driving motor 107c, the adjusting block 107d can be moved forward and backward on the screw rod 107b, thereby adjusting the lateral position of the grinding mechanism 200. The top of the adjustment block 107d is provided with a first electric push rod 107e. The first electric push rod 107e can perform telescopic movement. By the telescopic movement of the first electric push rod 107e, the longitudinal height of the transmission rod 201 can be adjusted, so that the transmission rod 201 can accurately extend into the inside of the valve body 105, preparing for the subsequent grinding operation; The grinding mechanism 200 is the core part of the whole device, mainly composed of a transmission rod 201, a clamping assembly 202, a first grinding assembly 203 and a second grinding assembly 204; The clamping assembly 202 is used to fix the valve body 105 to ensure that the valve body 105 does not shake during the grinding process, thus ensuring the grinding accuracy; The fixing ring 202a is sleeved on the surface of the transmission rod 201, and the first motor 202b is installed at the rear side of the fixing ring 202a. When the first motor 202b is started, its output end will drive the gear 202c to rotate. Since the gear 202c meshes with the tooth disc 202d, the rotation of the gear 202c will cause the tooth disc 202d to rotate accordingly. The clamping ring 202e is fixedly connected to the outside of the tooth disc 202d. Therefore, the clamping ring 202e will also rotate accordingly. A suction cup 202f is arranged at the rear side of the clamping ring 202e. When the transmission rod 201 moves to a suitable position, the suction cup 202f can adsorb on the inner wall of the valve body 105, firmly fixing the valve body 105 on the transmission rod 201 and rotating with the start of the motor. In this way, during the grinding process, the valve body 105 can remain stable and avoid affecting the grinding quality due to shaking; The first grinding assembly 203 is mainly used for grinding the inner wall of the annular or arc-shaped valve body 105; After the transmission rod 201 extends into the valve body 105 under the drive of the screw rod 107b, according to the shape of the inner wall of the valve body 105, the second electric push rod 203c is started, and its output end will push the extension plate 203d to extend outwards, so that the extension plate 203d drives the first grinding rod 203f to approach the inner wall of the valve body 105. A plurality of compression springs 203e are arranged at the top of the extension plate 203d. Due to the existence of the compression springs 203e, the first grinding rod 203f can adaptively fit the annular or arc-shaped shape of the inner wall of the valve body 105 to achieve flexible grinding. The compression springs 203e can expand and contract according to the concave and convex conditions of the inner wall to ensure that the first grinding rod 203f always maintains good contact with the inner wall, thereby improving the grinding effect. At the same time, the pulling grooves 205 and the first pulling springs 206 formed on the surface of the extension groove 203a can further enhance the stability of the first grinding rod 203f, so that it will not shake during the grinding process; The second grinding assembly 204 is mainly used for grinding the side of the inner wall of the valve body 105 in a vertical state; When it is necessary to polish the inner wall of the cylindrical valve body 105, the third electric push rod 204b is started, so that the pull rod 204c drives the second polishing rod 204d to extend out of the transmission rod 201 until the second polishing rod 204d contacts the inner wall of the valve body 105. At this time, as the first motor 202b drives the rotation of the clamping ring 202e, the valve body 105 is driven to rotate, so that the second polishing rod 204d can polish the side of the inner wall of the valve body 105 in a vertical state. The pull slot 212 and the pull cross bar 213 provided on the inner wall of the pull rod 204c can ensure that the second polishing rod 204d remains stable during the telescopic process and avoid deviation. At the same time, the cooperation of the rotating plate 207, the stroke rod 208, the stroke slot 209, the second pulling spring 210 and the extended polishing rod 211 on the inner wall of the clamping ring 202e can make the second polishing rod 204d better adapt to the shape of the inner wall of the valve body 105 during the polishing process and improve the polishing accuracy; When polishing valve bodies 105 with different diameters, due to the arrangement of the transverse groove 301 and the transverse block 302, when the transmission rod 201 moves towards the inside of the valve body 105, the suction cup 202f, the clamping ring 202e, the motor, etc. are squeezed by the surface of the valve body 105, so that the transverse block 302 moves on the surface of the transverse groove 301. Therefore, valve bodies 105 with different diameters can be adapted. Since a return spring 302a is provided between the transverse block 302 and the transverse groove 301, after the polishing is completed, the motor, the clamping ring 202e, the suction cup 202f, etc. can be reset, without affecting the subsequent polishing work; The main function of the waste chip collection system is to collect the waste chips generated during the polishing process and avoid the waste chips affecting the polishing quality and the working environment; When the suction pump 313 is started, a negative pressure will be formed inside the connecting block 307 and the suction ring 309, so that the waste chips generated during the polishing process are sucked into the suction pipe 308 through the suction ring 309. The suction pipe 308 then conveys the waste chips to the first suction pipe 311 and the second suction pipe 312, and finally into the collection box 314; In this way, the waste chips can be collected in time, avoiding remaining on the inner wall of the valve body 105, thus ensuring the polishing quality. At the same time, it can also reduce the pollution of the working environment by the waste chips and improve the safety and comfort of the work; The gradient arrangement of the extrusion springs 201e enables the first polishing rod 201f to provide a stable supporting force when contacting the inner wall of the valve body 105. The middle short extrusion springs 201e have a small compression amount and high stiffness, which can meet the rigid polishing requirements of small curvature areas. The outer long extrusion springs 201e have a large elastic deformation space and strong flexibility, and can adaptively expand and contract with the curvature of the large curvature area, avoiding the problem of "excessive pressure in the middle and insufficient contact on the outside" caused by the same stiffness of the extrusion springs 201e, ensuring a high degree of fit between the entire first polishing rod 201f and the inner wall surface, and thus achieving uniform polishing in the whole area.

[0051] It should be noted that the second grinding assembly 204 of the present application is only adaptable to grinding valve bodies 105 of the same model.

[0052] In summary: The support mechanism 100 adaptively adjusts the distance between the baffles 104 through the electric cylinder 106, and combines with the telescopic plate 306 driven by the fourth electric push rod 305 to achieve stable clamping and limiting of valve bodies 105 of different sizes; the first grinding assembly 203 uses the flexible connection of the extrusion spring 203e and the first pulling spring 206 to achieve adaptive fitting grinding of the annular or arc-shaped inner wall; the second grinding assembly 204 drives the pull rod 204c through the third electric push rod 204b, and combines with the linkage structure of the rotating plate 207 and the stroke rod 208 to accurately adapt to the grinding requirement that the side of the inner wall of the valve body 105 is in a vertical state.
