However, this method has the phenomenon of wearing the cam or the eccentric wheel, resulting in inaccurate movement of the reference part and difficulty in accurately controlling the rotation position of the cam or the eccentric wheel.

[0062] The following is a further description of the embodiments of the present application in conjunction with the accompanying drawings. Figure 1 , define the X axis as the first direction, the Y axis as the second direction, and the Z axis as the third direction.
[0063] See also Figures 1 to 3 The embodiment of the present application provides a positioning device 100 , including a base 10 , a positioning component 20 disposed in the base 10 , and a clamping component 30 , wherein the clamping component 30 abuts against the positioning component 20 .
[0064] For details, please refer to Figure 4 The base 10 is provided with a first slide groove 11 extending along the X-axis direction, two second slide grooves 12 both connected to the first slide groove 11 and mirror-symmetrically arranged on opposite sides of the first slide groove 11, and a through hole 13 connected to the first slide groove 11, the two second slide grooves 12 both extend along the Y-axis direction, and the through hole 13 penetrates the base 10 along the Z-axis direction. The base 10 is a plate-shaped structure, and the through hole 13 is a strip-shaped structural hole.
[0065] In this embodiment, the positioning assembly 20 includes a sliding member 21 disposed in the first slide groove 11, a positioning member 22 connected to one end of the sliding member 21, a driving handle 23 connected to one end of the sliding member 21 away from the positioning member 22, an unlocking member 24 disposed in the sliding member 21, a first elastic member 25 abutting against the unlocking member 24, and a third elastic member 26 disposed in the first slide groove 11 and abutting against the sliding member 21. The positioning member 22 and the driving handle 23 are disposed in reverse parallel along the Z-axis direction.
[0066] The sliding member 21 is slidably arranged in the first slide groove 11. The side of the sliding member 21 opposite to the two second slide grooves 12 is mirror-symmetrically provided with two limiting parts 211. Each limiting part 211 is provided with a vertical surface 2111 perpendicular to the X-axis direction on the side facing the driving handle 23, and a first inclined surface 2112 is provided on the side facing the positioning member 22. The angle between the first inclined surface 2112 and the vertical surface 2111 is an acute angle. The sliding member 21 is provided with a sliding hole 212 arranged along the Y-axis direction and opening toward the side wall of the first slide groove 11, and a limiting hole 213 arranged along the Z-axis direction and connected to the sliding hole 212. The width of the two ends of the sliding member 21 in the Y-axis direction is greater than the width of the middle part of the sliding member 21 in the Y-axis direction. The two ends of the sliding member 21 are adapted to the first slide groove 11 so that the first slide groove 11 limits the two ends of the sliding member 21 in the Y-axis direction.
[0067] See also Figure 4 and Figure 5 The sliding member 21 may be a plate-shaped structure, the width of the two ends is greater than the width of the middle part, and the width of the two ends is the same as the width of the first slide groove 11. The two ends of the sliding member 21 are used to limit the sliding member 21 when it slides along the first slide groove 11, so as to prevent the sliding member 21 from deviating in the Y-axis direction. The sliding hole 212 and the limiting hole 213 are both strip-shaped structure holes.
[0068] The vertical surface 2111 of the limiting portion 211 is perpendicular to the X-axis direction, and the angle between the extension direction of the first inclined surface 2112 and the extension direction of the vertical surface 2111 is in the range of 35°-55°. The angle between the extension direction of the first inclined surface 2112 and the extension direction of the vertical surface 2111 can be 35°, 40°, 45°, 50°, 55°, etc. Of course, the angle between the extension direction of the first inclined surface 2112 and the extension direction of the vertical surface 2111 can also be any angle between 35°-55°, which will not be described in detail here. In this embodiment, the angle between the extension direction of the first inclined surface 2112 and the extension direction of the vertical surface 2111 is preferably 45°.
[0069] See also Figure 1 , Figure 2 and Figure 3 The positioning member 22 is connected to the end of the sliding member 21 corresponding to the through hole 13 and passes through the through hole 13 to extend out of the base 10, and the driving handle 23 is connected to the end of the sliding member 21 away from the positioning member 22. The positioning member 22 is used to calibrate an external processing tool (not shown). The driving handle 23 is a columnar structure, and the driving handle 23 can be connected to an external power source, such as a cylinder, to drive the driving handle 23 to drive the sliding member 21 to move, thereby realizing automatic driving of the sliding member 21 to move. The operator can also hold the driving handle 23 and slide it along the X-axis direction to drive the sliding member 21 to move.
[0070] See also Figure 4 , Figure 5 and Figure 6 The unlocking member 24 is slidably disposed in the sliding hole 212. The unlocking member 24 includes two unlocking portions 241 that are symmetrically disposed and both extend out of the sliding member 21. The unlocking portion 241 includes a second inclined surface 242 and a third inclined surface 243 that are connected. The second inclined surface 242 is parallel to the first inclined surface 2112. The angle between the extension direction of the third inclined surface 243 and the extension direction of the vertical surface 2111 is in the range of 35°-55°, and the extension direction of the second inclined surface 242 intersects with the extension direction of the third inclined surface 243. The angle between the extension direction of the second inclined surface 242 and the extension direction of the vertical surface 2111 can be 35°, 40°, 45°, 50°, 55°, etc. Of course, the angle between the extension direction of the second inclined surface 242 and the extension direction of the vertical surface 2111 can also be any angle between 35°-55°, which will not be described in detail here. In the present embodiment, the angle between the extension direction of the second inclined surface 242 and the extension direction of the vertical surface 2111 is preferably 45°. The angle between the extension direction of the third inclined surface 243 and the extension direction of the vertical surface 2111 can be 35°, 40°, 45°, 50°, 55°, etc. Of course, the angle between the extension direction of the third inclined surface 243 and the extension direction of the vertical surface 2111 can also be any angle between 35°-55°, which will not be described in detail here. In the present embodiment, the angle between the extension direction of the third inclined surface 243 and the extension direction of the vertical surface 2111 is preferably 45°. The second inclined surface 242 and the third inclined surface 243 of the unlocking member 24 can be arranged in a symmetrical manner or in an asymmetrical manner.
[0071] See also Figure 3 and Figure 4 The unlocking member 24 is provided with a limit block 244 which is inserted into the limit hole 213 and protrudes from the unlocking member 24 body along the Z-axis direction. The limit block 244 can move along the X-axis direction in the limit hole 213. The limit block 244 is used to limit the movement direction of the unlocking member 24 in the Y-axis direction.
[0072] The first elastic member 25 is disposed in the sliding hole 212 along the X-axis direction, one end of the first elastic member 25 abuts against the side wall of the sliding hole 212 close to the positioning member 22, and the other end abuts against the unlocking member 24. The first elastic member 25 is a spring, and the first elastic member 25 is used to push the unlocking member 24 away from the limiting portion 211.
[0073] One end of the third elastic member 26 abuts against the end of the sliding member 21 away from the driving handle 23, and the other end of the third elastic member 26 abuts against the groove wall of the first sliding groove 11 to push the sliding member 21 to move in the opposite direction of the X-axis direction. In this embodiment, the elastic force of the third elastic member 26 is greater than the elastic force of the first elastic member 25.
[0074] See also Figure 3 , Figure 4 and Figure 5 In this embodiment, the clamping assembly 30 includes two clamping members 31 respectively arranged in the two second slide grooves 12 and arranged in a mirror-symmetrical manner. Each clamping member 31 abuts against one end of the sliding member 21 and is provided with a fourth inclined surface 311 parallel to the first inclined surface 2112 on the corresponding limiting portion 211, a fifth inclined surface 312 parallel to the third inclined surface 243, and an abutting surface 313 respectively connected to the fourth inclined surface 311 and the fifth inclined surface 312.
[0075] The clamping member 31 is a special-shaped structure, and one end thereof abutting against the sliding member 21 is provided with a fourth inclined surface 311, an abutting surface 313 and a fifth inclined surface 312 which are sequentially connected along the X-axis direction. The fourth inclined surface 311 is parallel to the first inclined surface 2112, and the angle between the extension direction of the fourth inclined surface 311 and the extension direction of the vertical surface 2111 is in the range of 35°-55°, and the angle between the extension direction of the fourth inclined surface 311 and the extension direction of the vertical surface 2111 can be 35°, 40°, 45°, 50°, 55°, etc. Of course, the angle between the extension direction of the fourth inclined surface 311 and the extension direction of the vertical surface 2111 can also be any angle between 35°-55°, which will not be described in detail here. The fifth inclined plane 312 is parallel to the third inclined plane 243, and the angle between the extension direction of the fifth inclined plane 312 and the extension direction of the vertical plane 2111 is in the range of 35°-55°. The angle between the extension direction of the fifth inclined plane 312 and the extension direction of the vertical plane 2111 can be 35°, 40°, 45°, 50°, 55°, etc. Of course, the angle between the extension direction of the fifth inclined plane 312 and the extension direction of the vertical plane 2111 can also be any angle between 35°-55°, which is not elaborated here.
[0076] In this embodiment, the area of the fifth inclined surface 312 is smaller than the area of the fourth inclined surface 311, so that when the retaining member 31 abuts against the vertical surface 2111, the side wall connecting the retaining member 31 and the fifth inclined surface 312 can contact the vertical surface 2111, thereby preventing the fifth inclined surface 312 from contacting the vertical surface 2111 and causing the retaining member 31 to be unable to be locked in place.
[0077] In this example, see Fig.11 When the unlocking member 24 moves along the X-axis direction to abut against the side wall of the sliding hole 212, the distance between the end of the unlocking member 24 in the Y-axis direction and the end of the corresponding limiting portion 211 is less than the length of the abutting surface 313 along the X-axis direction. In this way, it can be ensured that the holding member 31 contacts the limiting portion 211 before leaving the unlocking member 24, so as to avoid the holding member 31 sliding between the unlocking member 24 and the limiting portion 211 during unlocking, resulting in failure to unlock.
[0078] See also Figure 4 , Figure 5and Figure 6 In this embodiment, the clamping assembly 30 further includes two second elastic members 32 respectively disposed in the two second slide grooves 12 and arranged in mirror symmetry, one end of the second elastic member 32 abuts against the bottom of the corresponding second slide groove 12, and the other end pushes the corresponding clamping member 3 to abut against the sliding member 21. The second elastic member 32 is a spring, and the second elastic member 32 is used to push the clamping member 31 to move along the second slide groove 12 to abut against the sliding member 21. The elastic force of the second elastic member 32 is greater than the elastic force of the first elastic member 25, so that when the abutting surface 313 of the clamping member 31 contacts the end of the unlocking member 24, the second elastic member 32 can still push the clamping member 31 to clamp the unlocking member 24, so as to prevent the unlocking member 24 from moving out of the clamping member 31 under the action of the first elastic member 25, resulting in failure to unlock.
[0079] See also Figure 3 and Figure 5 In this embodiment, a locking groove 314 is further provided at one end of the clamping member 31 close to the sliding member 21, and a locking portion 121 corresponding to the locking groove 314 is provided at one end of the second sliding groove 12 close to the first sliding groove 11, and the locking portion 121 is locked in the locking groove 314 to limit the position of the clamping member 31. In this way, when the second elastic member 32 pushes the clamping member 31 to move along the second sliding groove 12 toward the first sliding groove 11, the clamping member 31 can be limited by the cooperation of the locking groove 314 and the locking portion 121, so as to prevent the clamping member 31 from excessively squeezing the sliding member 21 and causing wear of the clamping member 31 and the sliding member 21.
[0080] See also Figure 1 , Figure 2 and Figure 3 In this embodiment, the positioning device 100 further includes a cover plate 40 connected to the side of the base 10 where the first slide groove 11 is provided, and the cover plate 40 is provided with a strip hole 41, and the driving handle 23 passes through the strip hole 41 to extend out of the cover plate 40. The cover plate 40 is a plate-shaped structure, and the cover plate 40 is connected to the base 10, thereby limiting the positioning assembly 20 and the clamping assembly 30 in the Z direction, so that the positioning device 100 can be used at different angles.
[0081] The working process of the positioning device 100 provided in the embodiment of the present application is roughly as follows:
[0082] First, move the positioning member 22 to the standard position. Figure 5 and Figure 6 , the sliding member 21 is moved along the X-axis direction by driving the handle 23, and the two limiting parts 211 of the sliding member 21 cooperate with the corresponding fourth inclined surface 311 on the clamping member 31 through the first inclined surface 2112 to push the clamping member 31 into the second sliding groove 12, until the limiting part 211 passes over the clamping member 31 in the X-axis direction, and the clamping member 31 abuts against the sliding member 21 under the action of the second elastic member 32. See Figure 7 and Figure 8 At this time, the holding member 31 is located between the limiting portion 211 and the unlocking member 24, and the third elastic member 26 applies a force in the opposite direction of the X-axis direction to the sliding member 21. The vertical surface 2111 of the limiting portion 211 abuts against the side wall of the holding member 31, thereby realizing the locking of the sliding member 21 by the holding member 31. The positioning member 22 is now in the standard position.
[0083] When unlocking, see Fig. 9 , the sliding member 21 continues to move along the X-axis direction, and the unlocking member 24 pushes the clamping member 31 into the second slide groove 12 through the second inclined surface 242 and the fourth inclined surface 311, until the unlocking member 24 passes over the clamping member 31 in the X-axis direction. Then the driving handle 23 drives the sliding member 21 to move in the opposite direction of the X-axis direction, see Fig.10 At this time, the clamping member 31 pushes the unlocking member 24 until the side wall of the sliding hole 212 abuts against the unlocking member 24. Fig.11 , the clamping member 31 moves along the third inclined surface 243 through the fifth inclined surface 312 until the abutting surface 313 of the clamping member 31 contacts the end of the unlocking member 24. Since the elastic force of the second elastic member 32 is greater than the elastic force of the first elastic member 25, the clamping member 31 still clamps the unlocking member 24, and the position of the unlocking member 24 relative to the sliding member 21 remains unchanged. The sliding member 21 continues to move in the opposite direction of the X-axis direction until the abutting surface 313 contacts the limiting portion 211. The length of the abutting surface 313 is greater than the distance between the end of the unlocking member 24 and the limiting portion 211 at this time. Therefore, the abutting surface 313 contacts both the unlocking member 24 and the limiting portion 211 at this time. Then the sliding member 21 continues to move in the opposite direction of the X-axis direction until the fourth inclined surface 311 of the clamping member contacts the first inclined surface 2112 of the limiting portion 211, that is, the unlocking is completed, and the first elastic member 25 pushes the unlocking member 24 to reset, so as to facilitate the next movement of the positioning member 22 to the standard position.
