For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. Some embodiments of the present application will be described in detail below in conjunction with the accompanying drawings.

[0068] The following is a further description of the embodiments of the present application in conjunction with the accompanying drawings. Figure 1 In this embodiment, the horizontal X-axis direction is defined as the first direction, and the vertical Z-axis direction is defined as the second direction.

[0069] See also Figure 1 The embodiment of the present application provides a positioning device 100 for positioning a workpiece 200. The positioning device 100 includes a fixing seat 10 fixedly connected to an external mechanism 300, a clamping carrier 20 detachably connected to the fixing seat 10, and a positioning wrench 30 for fixing the clamping carrier 20. In this embodiment, the external mechanism 300 is a slow-moving wire cutting machine.

[0070] Please combine Figure 2A positioning groove 11 is provided on one side of the fixing seat 10. It can be understood that when the fixing seat 10 is fixedly installed on the external mechanism 300, the opening of the positioning groove 11 faces the position where the external mechanism 300 processes the workpiece 200. The positioning groove 11 includes a groove bottom 111 and two groove walls 112. The two groove walls 112 are both set as inclined surfaces, and the angles between the extension directions of the two groove walls 112 and the X-axis direction are both acute angles. The distance between the two groove walls 112 gradually increases along the X-axis direction. Each groove wall 112 is provided with a plurality of avoidance grooves 113, and the plurality of avoidance grooves 113 are arranged at intervals and are all extended along the Z-axis direction. The number of avoidance grooves 113 can be set to five, six, seven, etc. The specific number can be set according to the area of ​​the groove wall 112, which is not limited here. By providing the avoidance groove 113 , the contact area between the groove wall 112 and the clamping carrier 20 can be reduced, thereby reducing the probability of debris and other impurities adhering between the groove wall 112 and the clamping carrier 20 , which can effectively improve the accuracy of positioning the clamping carrier 20 .

[0071] The fixing seat 10 further defines a first through hole 12 that penetrates the fixing seat 10 along the X-axis direction and communicates with the positioning groove 11 . The first through hole 12 is formed at the groove bottom 111 .

[0072] See also Figure 1 , Figure 2 and Figure 3 The clamping carrier 20 is detachably connected to the fixing seat 10 , and the clamping carrier 20 includes a clamping seat 21 , a clamping plate 22 connected to one side of the clamping seat 21 , a pull rod 23 connected to the other side of the clamping seat 21 , and a connecting pin 24 movably connected to the pull rod 23 .

[0073] The material clamping seat 21 includes a first end 211 and a second end 212 opposite to each other, and the first end 211 abuts against the positioning groove 11. The first end 211 is provided with abutting surfaces 2112 corresponding to the two groove walls 112 one by one. When the material clamping seat 21 abuts against the positioning groove 11, the two abutting surfaces 2112 abut against the corresponding groove walls 112 respectively. Each abutting surface 2112 is provided with a plurality of bosses 2113 spaced apart from each other, and the diameter of each boss 2113 is greater than the width of the avoidance groove 113. By providing the abutting surface 2112, the first end 211 of the material clamping seat 21 can be accommodated in the positioning groove 11 to position the material clamping seat 21. The number of bosses 2113 on the abutting surface 2112 can be four, five, six, etc. By providing the bosses 2113 on the abutting surface 2112, the contact area between the abutting surface 2112 and the groove wall 112 of the positioning groove 11 can be reduced, thereby reducing the probability of debris and other impurities adhering to the surface of the bosses 2113 and the groove wall 112 of the positioning groove 11, and effectively improving the accuracy of positioning the material clamping seat 21. The second end 212 of the material clamping seat 21 is provided with a clamping surface 2121 and a connecting protrusion 2122 protruding from the clamping surface 2121 along the X-axis direction.

[0074] See also Figure 2 and Figure 3 The clamping plate 22 is connected to the connecting protrusion 2122 and is opposite to the clamping surface 2121. The clamping plate 22 cooperates with the clamping surface 2121 to clamp the workpiece 200. The clamping plate 22 is provided with a strip hole 221. The clamping carrier 20 further includes a connecting member 222 inserted into the strip hole 221 and connected to the connecting protrusion 2122, and a supporting member 223 movably connected to the clamping plate 22 and abutting against the connecting protrusion 2122. The connecting member 222 connects the clamping plate 22 and the connecting protrusion 2122, and the supporting member 223 supports the clamping plate 22. The connecting member 222 may be a bolt or the like, and the connecting member 222 is inserted into the strip hole 221 and connected to the connecting protrusion 2122. When the workpiece 200 is placed between the clamping surface 2121 and the clamping plate 22, the clamping plate 22 can be moved toward the workpiece 200 by adjusting the connecting member 222, so that the clamping plate 22 can cooperate with the clamping surface 2121 to clamp the workpiece 200. By providing the strip hole 221, it is convenient to adjust the length of the clamping plate 22 moving out from the connecting protrusion 2122, so as to adjust the clamping plate 22 according to different workpieces 200 and improve the stability of clamping the workpiece 200. The support member 223 can be a bolt, etc., and the support member 223 is movably connected to the clamping plate 22. When the clamping plate 22 clamps the workpiece 200, the length of the support member 223 connected between the clamping plate 22 and the connecting protrusion 2122 can be adjusted so that when the clamping plate 22 clamps the workpiece 200, the support member 223 abuts against the connecting protrusion 2122, thereby supporting one end of the clamping plate 22 away from the workpiece 200, further improving the stability of the clamping plate 22 when clamping the workpiece 200.

[0075] The pull rod 23 is connected to the first end 211 and extends along the X-axis direction. When the first end 211 abuts against the positioning groove 11, the pull rod 23 is inserted into the first through hole 12. In this embodiment, the pull rod 23 is a columnar structure. It can be understood that the structure of the pull rod 23 is adapted to the structure of the first through hole 12 to improve the stability of the pull rod 23 in the first through hole 12.

[0076] The connecting pin 24 is detachably connected to one end of the pull rod 23 away from the material clamping seat 21 and is extended along the Z-axis direction. In this embodiment, the connecting pin 24 is a columnar structure. It can be understood that when the pull rod 23 is inserted into the first through hole 12 or when the pull rod 23 is pulled out of the first through hole 12, the connecting pin 24 is first removed from the pull rod 23, and after the pull rod 23 is inserted into the first through hole 12, the connecting pin 24 is installed on the pull rod 23.

[0077] See also Figure 2 and Figure 3In this embodiment, a receiving groove 213 is provided between the first end 211 and the second end 212 of the clamping seat 21, and a second through hole 2111 extending along the X-axis direction and communicating with the receiving groove 213 is provided at the first end 211. The clamping carrier 20 also includes a limit block 25 and an elastic member 26 arranged in the receiving groove 213, the limit block 25 is arranged at a side where the receiving groove 213 is connected with the second through hole 2111, the limit block 25 is provided with a third through hole 251 extending along the X-axis direction and corresponding to the second through hole 2111, the pull rod 23 is movably inserted in the second through hole 2111 and the third through hole 251, and extends out of the limit block 25 along the X-axis direction, the elastic member 26 is arranged at a side of the limit block 25 away from the second through hole 2111 and is sleeved on the pull rod 23, one end of the elastic member 26 is fixedly connected to the pull rod 23, and the other end of the elastic member 26 abuts against the limit block 25. The elastic member 26 is a spring, which is sleeved on the pull rod 23. In this way, when the clamping carrier 20 is installed on the fixing seat 10, the two abutting surfaces 2112 of the clamping seat 21 abut against the two groove walls 112 of the positioning groove 11, and the pull rod 23 passes through the first through hole 12. At this time, the pull rod 23 is driven to move in the opposite direction of the X-axis direction, and the pull rod 23 drives the elastic member 26 to push the limit block 25 to move in the opposite direction of the X-axis direction. The limit block 25 then pushes the clamping seat 21 to abut against the positioning groove 11, so as to improve the accuracy of the position of the clamping seat 21 in the positioning groove 11.

[0078] See also Figure 3 In this embodiment, the clamping carrier 20 also includes a sealing cover plate 27 covering the receiving groove 213, and the sealing cover plate 27 is used to seal the receiving groove 213. By providing the sealing cover plate 27, the receiving groove 213 can be isolated from the external environment to prevent debris and other impurities from falling into the receiving groove 213, thereby affecting the movement of the elastic member 26 and the limit block 25, which is conducive to maintaining the positioning accuracy. In one embodiment, a sealing gasket (not shown) is provided between the sealing cover plate 27 and the clamping seat 21 to improve the effect of the sealing cover plate 27 sealing the receiving groove 213. In this embodiment, the sealing cover plate 27 is made of a transparent material such as acrylic to facilitate observation of the situation in the receiving groove 213.

[0079] In this embodiment, the clamping carrier 20 further includes a sealing ring 28 disposed in the second through hole 2111 and sleeved on the tie rod 23, and a baffle 29 connected to the first end 211, the baffle 29 is provided with a fourth through hole 291 communicating with the second through hole 2111, the radius of the fourth through hole 291 is larger than the radius of the tie rod 23 and smaller than the outer diameter of the sealing ring 28. In this embodiment, the sealing ring 28 is an annular rubber ring, and by providing the sealing ring 28, the sealing performance between the tie rod 23 and the limit block 25 can be improved, and impurities can be prevented from entering the receiving groove 213 from the gap between the second through hole 2111 and the tie rod 23. By providing the baffle 29, the tie rod 23 can be prevented from bringing the sealing ring 28 out of the second through hole 2111 when moving.

[0080] See also Figure 2 , Figure 3 and Figure 4 The positioning wrench 30 is used to clamp the connecting pin 24 when the pull rod 23 is inserted into the first through hole 12 to fix the clamping seat 21 to the positioning groove 11.

[0081] Please also see Figure 5 and Figure 6 The positioning wrench 30 includes a driving handle 31 and two claws 32 connected to one end of the driving handle 31 and spaced apart. Each claw 32 is provided with a slot 321 extending along the Z-axis direction and used to clamp the connecting pin 24. Each claw 32 is provided with a first abutting surface 322 and a second abutting surface 323. The first abutting surface 322 is parallel to the extension direction of the driving handle 31 and the Z-axis direction. The second abutting surface 323 is provided on the side of the claw 32 away from the driving handle 31 and perpendicular to the extension direction of the driving handle 31. In this embodiment, the driving handle 31 is a rod-shaped structure, and the claw 32 is a hook-shaped structure. When the two claws 32 clamp the connecting pin 24 through the slot 321, the pull rod 23 is located between the two claws 32, and the distance between the first abutting surface 322 and the connecting pin 24 is smaller than the distance between the second abutting surface 323 and the connecting pin 24. The driving handle 31 drives the two claws 32 to rotate around the connecting pin 24, so that when the first abutting surface 322 abuts against the fixed seat 10 and rotates to the second abutting surface 323 abuts against the fixed seat 10, the claws 32 pull the pull rod 23 to move in the opposite direction of the X-axis direction, thereby fixing the fixed seat 10 in the positioning slot 11.

[0082] See also Figure 1 , Figure 3 and Figure 7 The positioning device 100 further includes a clamping seat 40, a limiting groove 41 is provided on one side of the clamping seat 40, and the limiting groove 41 is used to accommodate the first end 211 of the clamping seat 21. The clamping seat 40 is provided with a limiting hole 42 that penetrates the clamping seat 40 and communicates with the limiting groove 41, and the limiting hole 42 is used to accommodate the pull rod 23 and the connecting pin 24. It can be understood that in this embodiment, the structure of the limiting groove 41 is the same as the structure of the positioning groove 11 of the fixed seat 10, so that the limiting groove 41 can accommodate the first end 211 of the clamping seat 21. The clamping seat 40 can be fixedly installed on a work table (not shown). When installing or removing the workpiece 200, the connecting pin 24 is inserted into the pull rod 23, and then the connecting pin 24 and the pull rod 23 are inserted into the limiting hole 42. At this time, the first end 211 of the clamping seat 21 abuts against the limiting groove 41, and then the workpiece 200 can be installed or removed on the clamping seat 21. The structure of the limiting groove 41 is adapted to the pull rod 23 and the connecting pin 24 , so as to prevent the clamping seat 21 and the pull rod 23 from rotating when the workpiece 200 is installed or removed.

[0083] The positioning device 100 provided in the embodiment of the present application can be fixedly connected to the external mechanism 300 through the fixed seat 10, so as to realize rapid positioning through the fixed seat 10, and the workpiece 200 can be fixed by the clamping carrier 20. When fixing the workpiece 200, the workpiece 200 is placed on the clamping surface 2121, and then the workpiece 200 is clamped by the clamping plate 22 in cooperation with the clamping seat 21. When positioning, the pull rod 23 is inserted into the first through hole 12 of the fixed seat 10, and the first end 211 of the clamping seat 21 is abutted against the positioning groove 11 of the fixed seat 10, and then the connecting pin 24 is inserted into the end of the pull rod 23 extending out of the first through hole 12, and then the connecting pin 24 is clamped by the positioning wrench 30, and then the clamping carrier 20 with the workpiece 200 fixed is fixedly connected with the fixed seat 10, so as to realize rapid positioning of the workpiece 200, which is simple to operate and convenient to use. During the process of processing the workpiece 200 , the operator can fix the workpiece 200 on another clamping carrier 20 , so as to replace the clamping carrier 20 after the processing is completed, thereby improving the efficiency of the processing operation.

After the connecting pin 24 is installed, the driving handle 31 is rotated, and the driving handle 31 drives the two claws 32 to rotate so that the second abutting surface 323 of the claw 32 abuts against the fixed seat 10. Since the distance between the first abutting surface 322 and the connecting pin 24 is greater than the distance between the second abutting surface 323 and the connecting pin 24, the claw 32 drives the pull rod 23 to move in the opposite direction of the X-axis direction through the connecting pin 24, and the pull rod 23 drives the elastic member 26 to move, and the elastic member 26 pushes the limit block 25 to move, and the limit block 25 pushes the clamping seat 21 to move in the opposite direction of the X-axis direction, thereby making the two abutting surfaces 2112 of the first end 211 of the clamping seat 21 close to the two groove walls 112 of the positioning groove 11, thereby completing the positioning of the clamping seat 21, that is, completing the positioning of the workpiece 200.

[0088] When processing the positioned workpiece 200, the workpiece 200 can be installed and fixed on another clamping carrier 20. After the processing of the workpiece 200 is completed, the clamping carrier 20 with the processed workpiece 200 installed can be removed, and the clamping carrier 20 with the unprocessed workpiece 200 installed can be immediately installed on the fixed seat 10 to improve work efficiency.
