Description

Technical Field

[0001] This invention relates to the field of fixture manufacturing technology, specifically a fixture processing device for automotive stamping parts. Background Technology

[0002] Automotive stamping parts are metal stamping parts that make up automotive components. Among automotive stamping parts, some become automotive components directly after stamping, while others require welding, machining, painting, or other processes before becoming automotive components. The most processed automotive stamping parts are stamped tubes. The stability of tube clamping is the key to tube processing. Most of the clamping used for tube clamping are clamping blocks that match the shape of the tube. The clamping blocks have a semi-circular concave surface with the same radius as the tube.

[0003] Existing clamping blocks, when clamping and fixing pipe fittings, cannot adjust the relative position between the clamping block and the pipe fitting after compression and fixing. During operations such as grinding and polishing, the clamping block creates dead angles on the pipe fitting surface, preventing comprehensive surface processing and resulting in poor performance. Furthermore, the inability to adjust the position and angle of the pipe fitting during clamping leads to poor processing results. Summary of the Invention

[0004] The purpose of this invention is to provide a fixture for processing automotive stamping parts, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A fixture for processing automotive stamping parts includes a worktable with multiple sets of parallel-arranged bearing rings on its surface. Multiple sets of annularly spaced fixed cylinders are fixedly installed on the inner wall of each bearing ring. A column is slidably installed inside each fixed cylinder, with one end extending to the outside of the fixed cylinder and rotatably mounted with a clamping wheel. A compression spring is fixedly installed inside the fixed cylinder, with its extension end connected to the column. An adjusting ring is rotatably installed inside each bearing ring. A driving component connected to the adjusting ring is provided on the side wall of each bearing ring, controlling the rotation of the adjusting ring within the bearing ring. A clamping mechanism is provided on the surface of each fixed cylinder, including a telescopic component and a tilting component. The telescopic component is located on the inner wall of the adjusting ring and connected to the column. The telescopic component is used to control the movement of the column within the fixed cylinder, thereby adjusting the position of the clamping wheel. The flipping component is located on the surface of the fixed cylinder and connected to the adjusting ring. The flipping component is used to control the fixed cylinder to rotate 90 degrees around its own axis within the bearing ring. The worktable surface is provided with a positioning mechanism, which includes a limiting component and a translation component. The limiting component is located on the worktable surface and on both sides of multiple sets of bearing rings. The limiting component is used to position the pipe above the worktable. The translation component is located on the worktable surface and connected to the bearing ring. The translation component is used to control the movement of the bearing ring on the worktable surface, thereby adjusting the relative position of the pipe and the clamping wheel.

[0007] As a further embodiment of the present invention: the driving component includes an annular positioning gear ring fixedly mounted on the surface of the adjusting ring, the positioning gear ring being located outside the bearing ring, a side plate fixedly mounted on the side wall of the bearing ring, a rotating column rotatably mounted on multiple sets of side plates, a positioning gear disk fixedly mounted on the surface of the rotating column, the positioning gear disk meshing with the positioning gear ring, and one end of the rotating column extending to the outside of the side plate and connected to a motor.

[0008] As a further aspect of the present invention: the telescopic assembly includes a traction rope fixedly installed at one end of a column located inside the cavity of the fixed cylinder, the end of the traction rope away from the column extending to the outside of the fixed cylinder and fixedly installed with a control block, the control block being made of magnetic material, a support rod fixedly installed on the inner wall of the adjusting ring, a magnetic block cooperating with the control block being fixedly installed at the end of the support rod away from the adjusting ring, and a baffle cooperating with the control block being fixedly installed on the surface of the fixed cylinder, the baffle being located outside the control block.

[0009] As a further aspect of the present invention: the flipping assembly includes a guide toothed disc fixedly mounted on the surface of the fixed cylinder, an arc-shaped rack fixedly mounted on the side wall of the adjusting ring, the rack meshing with the guide toothed disc, and a positioning element provided on the surface of the guide toothed disc. When the rack separates from the guide toothed disc, the positioning element is used to control the guide toothed disc and the fixed cylinder to stop rotating.

[0010] As a further embodiment of the present invention: the positioning component includes four sets of inner magnetic positioning blocks that are fixedly installed on the surface of the guide tooth disk and are distributed in a ring at equal intervals, and four sets of outer magnetic positioning blocks that are distributed in a ring at equal intervals around the fixed cylinder are fixedly installed on the inner side wall of the bearing ring.

[0011] As a further embodiment of the present invention: the limiting component includes a base provided on both sides of the worktable, the worktable surface is provided with a plurality of sets of parallelly distributed snap-fit ​​holes, the bottom wall of the base is fixedly installed with snap-fit ​​posts that cooperate with the snap-fit ​​holes, the base surface is fixedly installed with an L-shaped rod, and a limiting plate is provided at the end of the L-shaped rod away from the base.

[0012] As a further embodiment of the present invention: the translation component includes a base plate slidably mounted on the surface of the worktable, multiple sets of bearing rings fixedly mounted in parallel on the surface of the base plate, a fixing rod rotatably mounted on the surface of the base plate, and multiple sets of fixing grooves arranged in parallel and cooperating with the fixing rods on the surface of the worktable.

[0013] As a further embodiment of the present invention: a limiting vertical groove is formed on the inner side wall of the fixed cylinder, a limiting block is fixedly installed on the side wall of the column, and the limiting block is slidably installed in the limiting vertical groove.

[0014] As a further aspect of the present invention: an annular guide groove is provided on the inner sidewall of the bearing ring, a guide ring is rotatably installed in the guide groove, and the guide ring extends to the outside of the guide groove and is fixedly connected to the adjusting ring.

[0015] As a further embodiment of the present invention: the workbench surface is provided with two sets of oppositely distributed slides, and the bottom wall of the base plate is fixedly installed with a slider that is slidably connected to the slides.

[0016] Compared with existing technologies, the advantages of this invention are: by setting the translation component and the limiting component to cooperate with each other, the movement of the bearing ring on the worktable surface can be conveniently controlled, thereby adjusting the relative position of the clamping wheel and the pipe fitting. During the processing, the surface of the pipe fitting can be processed from all directions. This solves the problem that the clamping block forms a dead angle on the surface of the pipe fitting, making it impossible to process the surface of the pipe fitting from all directions, resulting in poor performance.

[0017] By combining the telescopic and tilting components, the position and angle of the clamping wheel and the pipe can be easily adjusted. When the axis of the clamping wheel is perpendicular to the axis of the pipe, the clamping wheel can stably clamp the pipe. When the axis of the clamping wheel is parallel to the axis of the pipe, the clamping wheel can control the pipe to rotate around its own axis while clamping it. This allows for convenient adjustment of the processing position and angle of the pipe, solving the problem of poor processing results caused by the inability to adjust the position and angle of the pipe during clamping.

Detailed Implementation

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0027] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The diagram shows a structural design of an automotive stamping part fixture processing device according to an embodiment of the present invention. It includes a worktable 1 with multiple sets of parallel-arranged bearing rings 2 on its surface. Multiple sets of annularly spaced fixed cylinders 21 are fixedly installed on the inner wall of each bearing ring 2. A column 22 is slidably installed inside each fixed cylinder 21, with one end extending to the outside of the fixed cylinder 21 and rotatably mounted with a clamping wheel 23. A compression spring 24 is fixedly installed inside the fixed cylinder 21, with its extension end connected to the column 22. An adjusting ring 3 is rotatably installed inside each bearing ring 2. A driving member 31 connected to the adjusting ring 3 is provided on the side wall of each bearing ring 2, controlling the rotation of the adjusting ring 3 inside the bearing ring 2. A clamping mechanism 4 is provided on the surface of each fixed cylinder 21, including a telescopic component 41 and... The rotating assembly 42 and the telescopic assembly 41 are located on the inner wall of the adjusting ring 3 and connected to the column 22. The telescopic assembly 41 is used to control the column 22 to move within the fixed cylinder 21 and thus adjust the position of the clamping wheel 23. The rotating assembly 42 is located on the surface of the fixed cylinder 21 and connected to the adjusting ring 3. The rotating assembly 42 is used to control the fixed cylinder 21 to rotate 90 degrees around its own axis within the bearing ring 2. The worktable 1 is provided with a positioning mechanism 5. The positioning mechanism 5 includes a limiting assembly 51 and a translation assembly 52. ​​The limiting assembly 51 is located on the surface of the worktable 1 and on both sides of the multiple bearing rings 2. The limiting assembly 51 is used to position the pipe above the worktable 1. The translation assembly 52 is located on the surface of the worktable 1 and connected to the bearing ring 2. The translation assembly 52 is used to control the bearing ring 2 to move on the surface of the worktable 1 and thus adjust the relative position of the pipe and the clamping wheel 23.

[0029] The translation component 52 supports and positions multiple sets of bearing rings 2 on the surface of the worktable 1, and the bearing rings 2 support and position multiple sets of fixed cylinders 21 and clamping wheels 23. Initially, the compression spring 24 applies a pushing force to the column 22 inside the fixed cylinder 21. At this time, the multiple sets of clamping wheels 23 are in a state of close proximity. When installing the pipe fitting, the driving component 31 controls the adjusting ring 3 to rotate inside the bearing ring 2. When the adjusting ring 3 rotates, the telescopic component 41 controls the column 22 to move towards the inner cavity of the fixed cylinder 21. At this time, the multiple sets of clamping wheels 23 move away from each other, allowing the pipe fitting to pass through between the multiple sets of clamping wheels 23. The driving component 31 controls the adjusting ring 3 to rotate in the opposite direction inside the bearing ring 2 back to its original position. At this time, the telescopic component 41 releases the restriction on the column 22, and the compression spring 24 pushes the column 22 to move towards the outside of the fixed cylinder 21. The clamping wheels 23 at the end of the column 22 are in contact with the surface of the pipe fitting and are compressed. At this time, the axial direction of the clamping wheels 23 is perpendicular to the axial direction of the pipe fitting. The multiple sets of clamping wheels 23 can stably clamp and position the pipe fitting. After the pipe fitting is clamped, the limiting component 51 can position both ends of the pipe fitting on the surface of the worktable 1, effectively preventing the pipe fitting from shifting to both sides. When the surface of the pipe fitting is ground and polished, the translation component 52 can control multiple sets of bearing rings 2 on the surface of the worktable 1. The bearing rings 2 drive multiple sets of fixed cylinders 21 in the inner cavity and the clamping wheels 23 to move synchronously. The clamping wheels 23 roll on the surface of the pipe fitting, which can conveniently adjust the relative position between the clamping wheels 23 and the pipe fitting, thereby preventing the clamping wheels 23 from always being in the same position on the surface of the pipe fitting. While clamping, the clamping wheels 23 can effectively avoid the presence of clamping dead angles on the surface of the pipe fitting, thereby enabling all-round grinding and polishing of the surface of the pipe fitting.

[0030] During processing, when the position and angle of the pipe need to be adjusted, the drive component 31 controls the adjusting ring 3 to rotate in the opposite direction. When the adjusting ring 3 rotates in the opposite direction, the flipping component 42 controls the fixed cylinder 21 to rotate 90 degrees at the inner side wall of the bearing ring 2. The fixed cylinder 21 drives the column 22 and the clamping wheel 23 to rotate 90 degrees synchronously. The clamping wheel 23 always supports and clamps the pipe when rotating. After rotating 90 degrees, the axis direction of the clamping wheel 23 is the same as the axis direction of the pipe. The multiple sets of clamping wheels 23 release the rotation restriction on the pipe, and the operator can push the pipe to rotate around its own axis, thereby conveniently adjusting the grinding and polishing position of the pipe.

[0031] like Figure 1 , Figure 4 , Figure 6As shown, in a preferred embodiment of the present invention, the driving component 31 includes an annular positioning gear ring 311 fixedly mounted on the surface of the adjusting ring 3. The positioning gear ring 311 is located outside the bearing ring 2. A side plate 312 is fixedly mounted on the side wall of the bearing ring 2. A rotating column 313 is rotatably mounted on multiple sets of side plates 312. A positioning gear disc 314 is fixedly mounted on the surface of the rotating column 313. The positioning gear disc 314 is meshed with the positioning gear ring 311. One end of the rotating column 313 extends to the outside of the side plate 312 and is connected to a motor 315.

[0032] In use, the motor 315 drives the rotating column 313 to rotate, and the rotating column 313 drives multiple sets of positioning gear discs 314 to rotate synchronously. The positioning gear discs 314 mesh with the positioning gear ring 311, which can drive the adjusting ring 3 to rotate inside the bearing ring 2. By adjusting the rotation direction of the motor 315, the rotation direction of the adjusting ring 3 inside the bearing ring 2 can be adjusted.

[0033] like Figure 3 , Figure 5 , Figure 6 , Figure 7 As shown, in a preferred embodiment of the present invention, the telescopic assembly 41 includes a traction rope 411 fixedly installed at one end of a column 22 located inside the cavity of the fixed cylinder 21. The end of the traction rope 411 away from the column 22 extends to the outside of the fixed cylinder 21 and is fixedly installed with a control block 412. The control block 412 is made of magnetic material. A support rod 413 is fixedly installed on the inner wall of the adjusting ring 3. A magnetic block 414 that cooperates with the control block 412 is fixedly installed at the end of the support rod 413 away from the adjusting ring 3. A baffle 415 that cooperates with the control block 412 is fixedly installed on the surface of the fixed cylinder 21. The baffle 415 is located outside the control block 412.

[0034] The support rod 413 positions the magnetic block 414 inside the adjusting ring 3. Initially, the magnetic block 414 and the control block 412 on the side wall of the fixed cylinder 21 are connected as a whole by magnetic attraction. When the adjusting ring 3 rotates, it drives the support rod 413 and the magnetic block 414 to rotate synchronously. The magnetic block 414 drives the control block 412 to rotate synchronously. When the control block 412 rotates, it cooperates with the traction rope 411 to pull the column 22 towards the inner cavity of the fixed cylinder 21. At this time, the multiple sets of clamping wheels 23 move away from each other, and the pipe passes through the multiple sets of clamping wheels 23. The adjusting ring 3 rotates in the opposite direction, and the adjusting ring 3 drives the magnetic block 414 to rotate synchronously in the opposite direction to the original position. At this time, the traction rope 411 releases the restriction on the column 22, and the compression spring 24 pushes the column 22 to move towards the outside of the fixed cylinder 21. The clamping wheel 23 at the end of the column 22 is in contact with the surface of the pipe and is squeezed.

[0035] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, in a preferred embodiment of the present invention, the flipping assembly 42 includes a guide gear disk 421 fixedly mounted on the surface of the fixed cylinder 21, and an arc-shaped rack 422 fixedly mounted on the side wall of the adjusting ring 3. The rack 422 meshes with the guide gear disk 421. A positioning element 423 is provided on the surface of the guide gear disk 421. When the rack 422 separates from the guide gear disk 421, the positioning element 423 is used to control the guide gear disk 421 and the fixed cylinder 21 to stop rotating.

[0036] During the processing, when the position angle of the pipe needs to be adjusted, the adjusting ring 3 rotates in the opposite direction inside the bearing ring 2. The adjusting ring 3 drives the magnetic block 414 to rotate in the opposite direction synchronously. At this time, the positioning component 423 positions the fixed cylinder 21, and the baffle 415 restricts the control block 412 at the side wall of the fixed cylinder 21. At this time, the control block 412 remains stationary at the side wall of the fixed cylinder 21. After the magnetic block 414 separates from the control block 412, the adjusting ring 3 drives the rack 422 to rotate synchronously when rotating in the opposite direction. The rack 422 meshes with the guide gear 421, which can drive the fixed cylinder 21 to rotate inside the bearing ring 2. After the fixed cylinder 21 rotates ninety degrees, the rack 422 and the guide gear 421 separate from each other, and the positioning component 423 controls the fixed cylinder 21 to stop rotating in time at the inner side wall of the bearing ring 2. The fixed cylinder 21 drives the column 22 and the clamping wheel 23 to rotate 90 degrees synchronously. The clamping wheel 23 supports and clamps the pipe fitting while rotating. After rotating 90 degrees, the axis of the clamping wheel 23 is in the same direction as the axis of the pipe fitting. The multiple sets of clamping wheels 23 release the rotation restriction on the pipe fitting, and the staff can push the pipe fitting to rotate around its own axis, thereby conveniently adjusting the grinding and polishing position of the pipe fitting.

[0037] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, in a preferred embodiment of the present invention, the positioning element 423 includes four sets of inner magnetic positioning blocks 4232 that are fixedly installed on the surface of the guide toothed disc 421 and are distributed in a ring at equal intervals. The inner sidewall of the bearing ring 2 is fixedly installed with four sets of outer magnetic positioning blocks 4231 that are distributed in a ring at equal intervals around the fixed cylinder 21.

[0038] Initially, the inner magnetic positioning block 4232 on the surface of the guide gear disk 421 is connected to the outer magnetic positioning block 4231 on the inner sidewall of the bearing ring 2 by magnetic attraction, forming a whole. At this time, the fixed cylinder 21 is stably located inside the bearing ring 2. When the fixed cylinder 21 rotates, the guide gear disk 421 drives the inner magnetic positioning block 4232 to rotate synchronously. At this time, the inner magnetic positioning block 4232 and the outer magnetic positioning block 4231 separate from each other. After the fixed cylinder 21 rotates 90 degrees, the rack 422 separates from the guide gear disk 421, and the inner magnetic positioning block 4232 on the surface of the guide gear disk 421 is connected to the outer magnetic positioning block 4231 again by magnetic attraction, forming a whole. At this time, the fixed cylinder 21 is once again stably located inside the bearing ring 2.

[0039] like Figure 1 , Figure 2 , Figure 3 As shown, in a preferred embodiment of the present invention, the limiting component 51 includes a base 511 disposed on both sides of the workbench 1. The surface of the workbench 1 has a plurality of sets of parallelly distributed snap-fit ​​holes 512. The bottom wall of the base 511 is fixedly installed with snap-fit ​​posts 513 that cooperate with the snap-fit ​​holes 512. An L-shaped rod 514 is fixedly installed on the surface of the base 511. A limiting plate 515 is disposed at the end of the L-shaped rod 514 away from the base 511.

[0040] The base 511 can be easily installed and removed on the surface of the workbench 1 by means of the interlocking hole 512 and the interlocking post 513. After the pipe is installed between multiple sets of bearing rings 2, the base 511 is installed on the surface of the workbench 1. The base 511 and the L-shaped rod 514 cooperate to position the limiting plate 515. The two sets of limiting plates 515 are respectively attached to the two ends of the pipe. The limiting plate 515 can effectively prevent the pipe from shifting during the clamping process.

[0041] like Figure 1 , Figure 2 As shown, in a preferred embodiment of the present invention, the translation component 52 includes a base plate 521 slidably mounted on the surface of the worktable 1, multiple sets of bearing rings 2 fixedly mounted in parallel on the surface of the base plate 521, a fixing rod 523 rotatably mounted on the surface of the base plate 521, and multiple sets of fixing grooves 522 arranged in parallel and cooperating with the fixing rods 523 on the surface of the worktable 1.

[0042] Initially, the fixing rod 523 on the surface of the base plate 521 is inserted into the fixing groove 522, and the base plate 521 remains relatively stationary on the surface of the worktable 1, positioning the bearing ring 2. When it is necessary to adjust the clamping position of the clamping wheel 23 on the pipe, the fixing rod 523 is rotated, causing the fixing rod 523 to cooperate with the fixing groove 522, pushing the base plate 521 to slide on the surface of the worktable 1. The base plate 521 drives the bearing ring 2 and the fixing cylinder 21 to move synchronously, thereby facilitating the adjustment of the relative position between the clamping wheel 23 and the pipe. After the clamping wheel 23 rolls to another position on the surface of the pipe, the fixing rod 523 is inserted into the fixing groove 522, and the base plate 521 again remains relatively stationary on the surface of the worktable 1, allowing the pipe to continue to be processed.

[0043] like Figure 4 , Figure 7 As shown, in a preferred embodiment of the present invention, a limiting vertical groove 6 is provided on the inner side wall of the fixed cylinder 21, and a limiting block 7 is fixedly installed on the side wall of the column 22. The limiting block 7 is slidably installed in the limiting vertical groove 6.

[0044] The movement of the limiting block 7 within the limiting vertical groove 6 can effectively prevent instability when the column 22 moves within the fixed cylinder 21.

[0045] like Figure 4 , Figure 7 As shown, in a preferred embodiment of the present invention, the inner wall of the bearing ring 2 is provided with an annular guide groove 8, and a guide ring 9 is rotatably installed in the guide groove 8. The guide ring 9 extends to the outside of the guide groove 8 and is fixedly connected to the adjusting ring 3.

[0046] like Figure 1 , Figure 2 As shown, in a preferred embodiment of the present invention, the workbench 1 has two sets of oppositely distributed slides 10 on its surface, and the bottom wall of the base plate 521 is fixedly installed with a slider that is slidably connected to the slides 10.

[0047] The working principle of this invention is as follows: Initially, the fixing rod 523 on the surface of the base plate 521 is inserted into the fixing groove 522, and the base plate 521 remains relatively stationary on the surface of the workbench 1, positioning the bearing ring 2. Initially, the compression spring 24 applies a pushing force to the column 22 inside the fixing cylinder 21. At this time, multiple sets of clamping wheels 23 are in a close-to-each-other state. When installing the pipe fitting, the motor 315 drives the rotating column 313 to rotate, and the rotating column 313 drives multiple sets of positioning gear discs 314 to rotate synchronously. The positioning gear discs 314 mesh with the positioning gear rings 311, which can drive the adjusting ring 3 to rotate inside the bearing ring 2. When the adjusting ring 3 rotates, it drives the support rod 413 and the magnetic block 414 to rotate synchronously. The magnetic block 414 drives the control block 412 to rotate synchronously. As the control block 412 rotates, it works in conjunction with the traction rope 411 to pull the column 22 towards the inner cavity of the fixed cylinder 21. At this time, the multiple sets of clamping wheels 23 move away from each other, allowing the pipe to pass through between them. The adjusting ring 3 rotates in the opposite direction, causing the magnetic block 414 to rotate synchronously in the opposite direction back to its original position. At this time, the traction rope 411 releases its restriction on the column 22, and the compression spring 24 pushes the column 22 towards the outside of the fixed cylinder 21. The clamping wheels 23 at the end of the column 22 come into contact with and compress the surface of the pipe. At this time, the axial direction of the clamping wheels 23 is perpendicular to the axial direction of the pipe, and the multiple sets of clamping wheels 23 can stably clamp and position the pipe. After the pipe fitting is clamped, the base 511 is installed on the surface of the workbench 1. The base 511 and the L-shaped rod 514 cooperate with each other to position the limiting plate 515. The two sets of limiting plates 515 are respectively attached to the two ends of the pipe fitting. The limiting plate 515 can effectively prevent the pipe fitting from shifting during the clamping process.

[0048] When it is necessary to adjust the clamping position of the clamping wheel 23 on the pipe fitting, the fixing rod 523 is rotated, causing the fixing rod 523 to cooperate with the fixing groove 522, pushing the base plate 521 to slide on the surface of the worktable 1. The base plate 521 drives the bearing ring 2 and the fixing cylinder 21 to move synchronously, thereby facilitating the adjustment of the relative position between the clamping wheel 23 and the pipe fitting. After the clamping wheel 23 rolls to another position on the surface of the pipe fitting, the fixing rod 523 is inserted into the fixing groove 522, and the base plate 521 remains relatively stationary on the surface of the worktable 1, allowing the pipe fitting to continue to be processed. When the clamping wheel 23 rolls on the surface of the pipe fitting, the relative position between the clamping wheel 23 and the pipe fitting can be easily adjusted, thus preventing the clamping wheel 23 from always being in the same position on the surface of the pipe fitting. While clamping, the clamping wheel 23 can effectively avoid the existence of clamping dead angles on the surface of the pipe fitting, thereby allowing for all-round grinding and polishing of the surface of the pipe fitting.

[0049] During the processing, when the position angle of the pipe needs to be adjusted, the control adjusting ring 3 rotates in the opposite direction inside the bearing ring 2. The adjusting ring 3 drives the magnetic block 414 to rotate in the opposite direction synchronously. At this time, the positioning component 423 positions the fixed cylinder 21, and the baffle 415 restricts the control block 412 at the side wall of the fixed cylinder 21. At this time, the control block 412 remains stationary at the side wall of the fixed cylinder 21. After the magnetic block 414 separates from the control block 412, the adjusting ring 3 drives the rack 422 to rotate synchronously when rotating in the opposite direction. The rack 422 meshes with the guide gear 421, which can drive the fixed cylinder 21 to rotate inside the bearing ring 2. After the fixed cylinder 21 rotates ninety degrees, the rack 422 and the guide gear 421 separate from each other, and the positioning component 423 controls the fixed cylinder 21 to stop rotating in time at the inner side wall of the bearing ring 2. The fixed cylinder 21 drives the column 22 and the clamping wheel 23 to rotate 90 degrees synchronously. The clamping wheel 23 supports and clamps the pipe fitting while rotating. After rotating 90 degrees, the axis of the clamping wheel 23 is in the same direction as the axis of the pipe fitting. The multiple sets of clamping wheels 23 release the rotation restriction on the pipe fitting, and the staff can push the pipe fitting to rotate around its own axis, thereby conveniently adjusting the grinding and polishing position of the pipe fitting.

[0050] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
