[0055] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0056] See also Figure 1 The present application provides a grinding positioning device 100 for positioning a workpiece 200. The workpiece 200 may be a small component with a relatively complex structure, such as a key. The grinding positioning device 100 includes a driving component 10, a transmission component 20, and a positioning component 30. In this embodiment, the workpiece 200 has a groove 201 (see Figure 4 ) annular structure, the positioning assembly 30 is inserted into the groove 201 of the workpiece 200 to clamp the internal support and position the workpiece 200.

[0057] Specifically, see Figure 1 The drive assembly 10 and the transmission assembly 20 can be connected to a support plate 40 to stably support the drive assembly 10 and the transmission assembly 20. It can be understood that the drive assembly 10 and the transmission assembly 20 can also be connected to the table of other processing equipment for easy use.

[0058] See also Figure 1 and Figure 2The transmission assembly 20 includes a connection seat 21 and a transmission member 22. The connection seat 21 is arranged adjacent to the driving assembly 10. The transmission member 22 includes a first end 221 and a second end 222 opposite to each other. The transmission member 22 is rotatably connected to the connection seat 21, and the first end 221 is in transmission connection with the driving assembly 10. The connection seat 21 may be a block structure, and the transmission member 22 may be a columnar structure. The transmission member 22 and the connection seat 21 may be connected by a bearing or the like to improve the stability of the connection between the transmission member 22 and the connection seat 21. The first end 221 and the second end 222 of the transmission member 22 both protrude from the connection seat 21, so as to facilitate the connection of the transmission member 22 with the driving assembly 10 and the positioning assembly 30. The first end 221 of the transmission member 22 may be directly connected to the driving assembly 10, or connected by other means, such as installing a gear on the first end 221, and then connecting to the driving assembly 10 through the gear.

[0059] See also Figure 1 , Figure 3 and Figure 4 The positioning assembly 30 includes a connecting rod 31, a positioning column 32, a holding member 33, a first elastic member 34, a plurality of holding members 35 and a plurality of second elastic members 36. One end of the connecting rod 31 is connected to the second end 222. The connecting rod 31 is provided with a through hole 311 extending along the axial direction of the connecting rod 31. One end of the positioning column 32 is connected to an end of the connecting rod 31 away from the second end 222. The end of the positioning column 32 away from the connecting rod 31 is used to carry the workpiece 200. The positioning column 32 is provided with a receiving groove 321 extending along the axial direction of the positioning column 32 and connected to the through hole 311. The end of the positioning column 32 away from the connecting rod 31 is also provided with a plurality of movable holes 322 arranged around the positioning column 32 and connected to the receiving groove 321. The holding member 33 is movably arranged in the through hole 311. The first elastic member 34 is arranged in the through hole 311, and the two ends of the first elastic member 34 are respectively abutted against the transmission member 22 and the abutting member 33 to push the abutting member 33 to move away from the transmission member 22, the clamping member 35 includes a main body 351 and a clamping portion 352, the main body 351 is arranged in the accommodating groove 321 and abuts against the abutting member 33, the clamping portion 352 is movably arranged in the movable hole 322, and multiple second elastic members 36 are all arranged in the accommodating groove 321 along the radial direction of the positioning column 32 and abut against the main body 351, the abutting member 33 pushes multiple main bodies 351 to move away from the axis of the positioning column 32 so that the clamping portion 352 extends out of the movable hole 322, and then the multiple clamping portions 352 abut the workpiece 200 to position the workpiece 200.

[0060] See also Figure 1 , Figure 3 and Figure 4The connecting rod 31 may be a tubular structure, extending along the axial direction of the transmission member 22, the positioning column 32 may be a columnar structure, extending along the axial direction of the connecting rod 31, the receiving groove 321 is connected to the through hole 311, and the abutting member 33 may be a columnar structure, disposed in the through hole 311 and the receiving groove 321, and may slide in the through hole 311 and the receiving groove 321. The first elastic member 34 may be a spring, and the first elastic member 34 is used to elastically push the abutting member 33, so that the abutting member 33 pushes the clamping member 35. The clamping member 35 may be a special-shaped structure, such as an L-shaped structure, the part disposed in the receiving groove 321 is the main body 351, and the part inserted in the movable hole 322 is the clamping portion 352. The second elastic member 36 may be a spring, and is used to elastically push the main body 351 to move toward the axis of the positioning column 32, thereby driving the clamping portion 352 to move into the movable hole 322.

[0061] The number of the clamping members 35 can be three, four, six, etc., as long as the workpiece 200 can be stably supported. The number of the second elastic members 36 is consistent with the number of the clamping members 35, and the second elastic members 36 correspond to the main body 351 of the clamping members 35. It can be understood that the number of the movable holes 322 on the positioning column 32 is consistent with the number of the clamping members 35, so that each clamping member 35 has a corresponding movable hole 322 to accommodate the clamping portion 352.

[0062] The resisting member 33 pushes the multiple clamping members 35 away from the axis of the positioning column 32, so that the clamping portion 352 protrudes out of the movable hole 322 to clamp the workpiece 200 and realize the positioning of the workpiece 200. The resisting member 33 moves away from the clamping member 35 so that the second elastic member 36 pushes the corresponding clamping member 35 toward the axis of the receiving groove 321, so that the clamping portion 352 releases the workpiece 200.

[0063] When the grinding and positioning device 100 provided in the embodiment of the present application is clamping and positioning the workpiece 200, the positioning assembly 30 can be used to position the workpiece 200, the abutting member 33 moves away from the clamping member 35, and the second elastic member 36 pushes the corresponding clamping member 35 to move toward the axis of the positioning column 32, thereby causing the clamping portion 352 of the clamping member 35 to retract into the movable hole 322, and then the workpiece 200 is placed on the end of the positioning column 32 away from the connecting rod 31, and the workpiece 200 corresponds to the movable hole 322. Then, the abutting member 33 is released, and the first elastic member 34 pushes the abutting member 33 to move toward the clamping member 35, and the abutting member 33 pushes multiple clamping members 35 away from the axis of the positioning column 32, so that the clamping portion 352 extends out of the movable hole 322 and then abuts against the workpiece 200, thereby achieving clamping and positioning of the workpiece 200. The operator only needs to move the abutting member 33 to clamp and position the workpiece 200, which is easy to operate. The clamping parts 352 of the multiple clamping members 35 abut against the inner wall of the workpiece 200, and the positioning accuracy is high. After the positioning is completed, the driving component 10 can drive the positioning component 30 to rotate through the transmission component 20, and then drive the workpiece 200 to rotate, which is convenient for polishing and grinding the workpiece 200.

[0064] In some embodiments, see Figure 2 , Figure 3 and Figure 4 The side wall of the connecting rod 31 is also provided with a strip hole 312 extending along the radial direction of the connecting rod 31 and communicating with the through hole 311. The positioning assembly 30 further includes a lever 37, which is movably disposed in the strip hole 312 and connected to the abutting member 33. The lever 37 is used to drive the abutting member 33 to move away from the clamping portion 352. The lever 37 may be in the shape of a rod, which is connected to the abutting member 33, and the abutting member 33 may be driven to slide by pushing the lever 37.

[0065] In some embodiments, see Figure 3 and Figure 4, a first inclined surface 353 is provided on the side of each main body 351 that contacts the abutting member 33, and the first inclined surface 353 gradually approaches the axis of the positioning column 32 in the direction away from the transmission member 22. A plurality of second inclined surfaces 331 are provided on the end of the abutting member 33 that contacts the main body 351, and the plurality of second inclined surfaces 331 are respectively provided corresponding to the plurality of first inclined surfaces 353. When the abutting member 33 moves in the direction away from the transmission member 22, the second inclined surfaces 331 push the first inclined surfaces 353 to move the plurality of clamping members 35 away from the axis of the positioning column 32. It can be understood that the number of the second inclined surfaces 331 provided on the abutting member 33 is consistent with the number of the clamping members 35, and each first inclined surface 353 is correspondingly abutted against one second inclined surface 331. In this way, when the supporting member 33 moves in a direction away from the transmission member 22 under the action of the first elastic member 34, the second inclined surface 331 pushes the first inclined surface 353, so that the clamping member 35 can move away from the axis of the positioning column 32, and then the clamping portion 352 extends out of the movable hole 322, and then multiple clamping portions 352 simultaneously abut against the inner wall of the groove 201 of the workpiece 200 to achieve the positioning of the workpiece 200.

[0066] In some embodiments, see Figure 3 and Figure 4 , a plurality of guide grooves 323 are provided in the positioning column 32 and are arranged around the receiving groove 321. The plurality of guide grooves 323 are all connected to the receiving groove 321. The main body 351 is arranged in the guide grooves 323. The guide grooves 323 are used to limit the main body 351. By providing the guide grooves 323, the movement direction of the main body 351 of the clamping member 35 can be limited, so that the main body 351 can only move along the radial direction of the receiving groove 321, thereby improving the stability of the movement of the clamping member 35, and preventing the clamping member 35 from rotating in the receiving groove 321, so that the clamping portion 352 can no longer move in the movable hole 322. The number of guide grooves 323 is consistent with the number of clamping members 35, so that each clamping member 35 can be arranged in the corresponding guide groove 323. It can be understood that the number of guide grooves 323 can be consistent with the number of movable holes 322, and each movable hole 322 is connected to a corresponding guide groove 323.

[0067] In some embodiments, a positioning portion 324 is provided at one end of the positioning column 32 away from the connecting rod 31, and the positioning portion 324 is used to abut against the inner wall of the workpiece 200 and then stop the workpiece 200 to limit the position of the workpiece 200. In this way, when the workpiece 200 is installed on the positioning column 32, the positioning portion 324 is inserted into the groove 201 of the workpiece 200. When the positioning portion 324 abuts against the bottom of the groove 201 of the workpiece 200, the workpiece 200 can be restricted from continuing to move toward the positioning column 32, so as to achieve the function of limiting the position of the workpiece 200 on the positioning column 32.

[0068] In some embodiments, the clamping member 35 is further provided with an anti-slip member 354, which is provided at one end of the clamping portion 352 away from the axis of the positioning column 32, and is used to increase the friction between the workpiece 200 and the clamping portion 352. The anti-slip member 354 can be a rubber pad, etc., to increase the friction between the clamping portion 352 and the workpiece 200, and further improve the stability when positioning the workpiece 200.

[0069] In some embodiments, see Figure 1 , Figure 2 and Figure 4 , there are multiple transmission members 22, and the multiple transmission members 22 are all arranged on the connecting seat 21 and are parallel to each other. The first ends 221 of adjacent transmission members 22 are transmission-connected, and the first end 221 of one transmission member 22 is transmission-connected with the driving assembly 10, and the second end 222 of each transmission member 22 is correspondingly connected with the positioning assembly 30. The number of transmission members 22 can be two, three, four, etc., and the first ends 221 of multiple transmission members 22 are transmission-connected in sequence. The first ends 221 of the transmission members 22 can be connected with gears, etc., so that the multiple transmission members 22 can rotate simultaneously through the gear connection. The driving assembly 10 is connected to the first end 221 of one of the transmission members 22, so that when the driving assembly 10 drives the transmission member 22 to rotate, the other transmission members 22 rotate simultaneously with the transmission member 22. The second end 222 of each transmission member 22 is correspondingly connected with the positioning assembly 30, so that multiple workpieces 200 can be positioned at the same time, thereby improving the efficiency of the grinding process.

[0070] In some embodiments, see Figure 1 and Figure 4 , multiple transmission members 22 are arranged at intervals, and the transmission assembly 20 also includes multiple synchronous wheels 23 connected to the connecting seat 21. The multiple synchronous wheels 23 are staggered with the multiple transmission members 22. Each synchronous wheel 23 is connected to the first end 221 of two adjacent transmission members 22. The synchronous wheels 23 are used to transmit so that the multiple transmission members 22 rotate in the same direction. The synchronous wheels 23 can be gears. By setting the synchronous wheels 23, the multiple transmission members 22 can rotate in the same direction. In this way, the workpieces 200 installed on the multiple positioning assemblies 30 can rotate in the same direction, thereby improving the consistency of the grinding effect. At the same time, it is also convenient for operators to manipulate the levers 37 on the multiple positioning assemblies 30 to facilitate loading and unloading.

[0071] In some embodiments, see Figure 1 and Figure 4The driving assembly 10 includes a driving member 11 and a synchronous belt 12 connected to the driving member 11. The driving member 11 is spaced apart from the first end 221 of the transmission member 22. The synchronous belt 12 is in transmission connection with the first end 221 of one of the transmission members 22. The driving member 11 drives the transmission member 22 to rotate through the synchronous belt 12. The driving member 11 can be a rotary cylinder, a rotary motor, etc., and the synchronous belt 12 can be a conveyor belt, a transmission chain, etc. It can be understood that the output end of the driving member 11 and the first end 221 of one of the transmission members 22 can be installed with a pulley, a gear, etc., so that the driving member 11 is in transmission connection with one of the transmission members 22 through the synchronous belt 12. The driving member 11 is connected to the transmission member 22 through the synchronous belt 12, and the position of the driving member 11 can be relatively freely set, so as to avoid other equipment (not shown) and facilitate loading and unloading.

[0072] In some embodiments, see Figure 3 , the elastic force of the first elastic member 34 is greater than the elastic force of the second elastic member 36. Thus, when the lever 37 is released, that is, when no external force is applied to the abutting member 33, the first elastic member 34 can push the abutting member 33 to move away from the transmission member 22, and further push the clamping member 35 to move away from the axis of the accommodating groove 321.

[0073] In one embodiment, see Figure 4 , the plurality of guide grooves 323 are centrally symmetrically arranged around the axis of the receiving groove 321. It can be understood that the guide groove 323 is used to accommodate the main body 351 of the clamping member 35, and the plurality of guide grooves 323 are centrally symmetrically arranged, and the plurality of clamping members 35 are also centrally symmetrically arranged, so that the clamping portions 352 of the plurality of clamping members 35 can be evenly held against the inner wall of the groove 201 of the workpiece 200, thereby improving the stability of supporting the workpiece 200.

[0074] The working process of the polishing and positioning device 100 provided in the embodiment of the present application is roughly as follows:

[0075] First, the operator moves the lever 37, thereby driving the abutting member 33 to move toward the transmission member 22 in the through hole 311, and the abutting member 33 compresses the first elastic member 34. At this time, the second elastic member 36 pushes the main body 351 of the clamping member 35 to move toward the axis of the positioning column 32, and the clamping portion 352 of the clamping member 35 retracts into the movable hole 322. Then, the workpiece 200 is placed on the positioning portion 324 of the positioning column 32, and the positioning portion 324 abuts against the bottom of the groove 201 of the workpiece 200, thereby achieving preliminary positioning of the workpiece 200. Then the operator releases the lever 37, the first elastic member 34 pushes the supporting member 33 to move away from the transmission member 22, and the second inclined surface 331 of the supporting member 33 pushes the first inclined surface 353 of the clamping member 35, so that the multiple clamping members 35 move away from the axis of the positioning column 32, and then the clamping portion 352 extends out of the movable hole 322 and abuts against the groove wall of the groove 201 of the workpiece 200. The multiple clamping portions 352 simultaneously abut against the groove wall of the workpiece 200, which can stably support the workpiece 200.

[0076] Then, the driving member 11 drives one of the transmission members 22 to rotate through the synchronous belt 12, and the transmission member 22 is driven by the synchronous wheel 23, so that multiple transmission members 22 rotate synchronously, and then multiple positioning components 30 drive the workpiece 200 to rotate synchronously. With the external grinding equipment, the workpiece 200 can be ground.

[0077] When disassembling the workpiece 200, the operator pushes the lever 37, and the lever 37 drives the supporting member 33 to move toward the transmission member 22 in the through hole 311. The supporting member 33 compresses the first elastic member 34.
