[0038] Please refer to Figs. 1 to 3 The embodiment of the present application provides a positioning tool for positioning a target workpiece, the positioning tool comprising a base 10, a positioning block 20 detachably mounted on the base 10, and a pressing structure 30 arranged above the positioning block 20, the positioning block 20 having a positioning surface 21 for supporting the target workpiece 200, the positioning surface 21 being adapted to the shape of the bottom surface of the target workpiece 200 to position the target workpiece 200, and the pressing structure 30 being used for clamping the target workpiece 200 together with the positioning surface 21.
[0039] Understandably, the positioning block 20 is detachably mounted on the top surface of the base 10, and the target workpiece 200 is arranged on the top surface of the positioning block 20, and the positioning block 20 can support the target workpiece 200.
[0040] Understandably, when the target workpiece 200 is arranged on the top surface of the positioning block 20, the positioning surface 21 is in contact with the bottom surface of the target workpiece 200, and the shape of the bottom surface of the target workpiece 200 can be a regular shape or an irregular shape different from the common square, circular and other shapes, and the positioning of the present application can be adapted to the shape of the bottom surface of the target workpiece 200, that is, the positioning surface 21 is a profiling surface adapted to the profile of the bottom surface of the target workpiece 200.
[0041] The positioning tool provided in the application, in use, places the target workpiece 200 on the positioning surface 21, and then fixes the target workpiece 200 on the positioning surface 21 by the pressing structure 30. Since the positioning surface 21 is matched with the shape of the bottom surface of the target workpiece 200, the stable positioning of the target workpiece 200 can be realized. In addition, for other specifications of the target workpiece 200, the corresponding target workpiece 200 can be quickly matched by selecting the appropriate positioning block 20, thereby improving the versatility of the positioning tool.
[0042] In some embodiments, the positioning surface 21 is a special-shaped surface. Since the profile surface shape of the target workpiece 200 can be an irregular shape different from the common square, circular and other shapes, that is, the target workpiece 200 is a special-shaped workpiece, the profile surface of the target workpiece 200 has a non-typical shape feature. For such target workpiece 200, the positioning surface 21 is correspondingly provided as a special-shaped surface, which can not only improve the stability of positioning, but also further improve the versatility of the positioning tool.
[0043] In some embodiments, the positioning surface 21 includes a plurality of support surfaces 211 arranged in sequence along the first direction a and connected to each other, and the plurality of support surfaces 211 have a height difference along the vertical direction.
[0044] It can be understood that the first direction a is parallel to the horizontal direction, and when the target workpiece 200 is arranged on the top surface of the positioning block 20, the bottom surface of the target workpiece 200 is not flat, but can be formed by a plurality of surfaces connected. Therefore, the positioning surface 21 of the embodiment of the application includes a plurality of support surfaces 211 arranged in sequence along the first direction a and connected to each other, so that the plurality of support surfaces 211 can support the plurality of surfaces of the target workpiece 200 respectively, thereby making the fixed state of the target workpiece 200 more stable.
[0045] In the embodiment of the application, the plurality of support surfaces 211 have a height difference along the vertical direction, and the heights of the plurality of support surfaces 211 can be arranged in a certain rule, such as gradually decreasing along the first direction a, or the heights of the plurality of support surfaces 211 can gradually decrease along the first direction a. Of course, in other possible embodiments, alternatively, the heights of the plurality of support surfaces 211 can be irregularly arranged, that is, the plurality of support surfaces 211 extend in a fluctuating manner.
[0046] It can be understood that the bottom surface of the target workpiece 200 can include a convex structure or a concave structure, and when the target workpiece 200 is arranged on the top surface of the positioning block 20, the support surface 211 with a higher height in the positioning surface 21 can correspond to the concave structure of the target workpiece 200 and support the concave structure, and the support surface 211 with a lower height in the positioning surface 21 can correspond to the convex structure of the target workpiece 200 and support the convex structure.
[0047] In some embodiments, the support surface 211 is curved, and specifically, the support surface 211 can be convex relative to the pressing structure 30, i.e., the support surface 211 is upwardly convex relative to the pressing structure 30. Of course, the support surface 211 can also be concave relative to the pressing structure 30, i.e., the support surface 211 is downwardly concave relative to the pressing structure 30. Of course, in other possible embodiments, the support surface 211 can also be planar, or the support surface 211 can also be irregularly shaped, and the embodiments of the present application do not limit the shape of the support surface 211.
[0048] In some embodiments, the plurality of support surfaces 211 extend along a second direction b, and the first direction a and the second direction b are arranged at an angle.
[0049] Optionally, the angle between the first direction a and the second direction b is ninety degrees, i.e., the first direction a and the second direction b are perpendicular to each other. Of course, in other possible embodiments, the angle between the first direction a and the second direction b can also be other values, and the embodiments of the present application do not limit the angle between the first direction a and the second direction b.
[0050] It can be understood that the target workpiece 200 of the embodiments of the present application can be a long sheet structure, and the target workpiece 200 has a certain extension length, and therefore the plurality of support surfaces 211 extending along the second direction b can be more suitable for the target workpiece 200, increase the contact area with the target workpiece 200, and thus further improve the positioning effect.

[0055] Specifically, the mounting rod 32 can extend along the first direction a, and the pressing rod 33 extends along the vertical direction.
[0056] In some embodiments, the lower pressing structure 30 further comprises a buffer 34 arranged at one end of the pressing rod 33 towards the positioning surface 21, the buffer 34 is used to buffer the vibration generated by the pressing rod 33 to the target workpiece 200 when the pressing rod 33 contacts the target workpiece 200, so as to avoid rigid contact between the pressing rod 33 and the target workpiece 200, and prevent damage to the pressing rod 33 and the target workpiece 200.
[0057] Specifically, the buffer 34 can be a buffer pad wrapped around one end of the pressing rod 33 towards the positioning surface 21, and the buffer pad can be made of rubber, silicone or sponge, so that the buffer 34 has elasticity and softness.
[0058] In some embodiments, the positioning tool further comprises a mounting base 40 detachably mounted on the top surface of the base 10, the mounting base 40 is arranged beside the positioning block 20, the support block 31 is fixed to the mounting base 40, and the position of the mounting base 40 along the extension direction of the side wall of the positioning block 20 is adjustable.

[0060] Specifically, the position of the mounting base 40 along the extension direction of the long axis side of the positioning block 20 is adjustable, that is, the position of the mounting base 40 along the second direction b is adjustable.
[0061] In some embodiments, two pressing structures 30 are arranged at intervals, and the two pressing structures 30 are arranged on opposite sides of the positioning block 20 respectively.
