The fixture 100 includes a body 104 and a limit block 101 . The limit block 101 is connected to the body 104 via a fastening screw 105 .

[0032] Reference Figure 4 and Figure 5 As shown, the positioning device 200 includes a support seat 1, a movable component 2 and a locking member 3. The support seat 1 includes a support member 11 and a limiting member 12. The support member 11 is set to be square. The shape of the support member 11 corresponds to the shape of the fixture 100 to facilitate the positioning of the limiting block 101 of the fixture 100. The support member 11 includes a hollow portion 111. When the positioning device 200 is placed on the fixture 100, the position of the hollow portion 111 corresponds to the position of the limiting block 101 of the fixture 100, and the support member 11 is provided with a limiting groove 112. Two limiting members 12 are provided, and the two limiting members 12 are respectively connected to the two sides of the support member 11, so that the lower surface of the limiting member 12 and the limiting groove 112 are enclosed to form a groove.

[0033] The movable assembly 2 includes a movable member 21 , which is movably disposed in the groove. The movable member 21 includes an abutting portion 211 , which is used to abut against the limiting block 101 of the positioning fixture 100 .

[0034] The locking member 3 passes through the supporting member 11 and the limiting member 12 , and is connected to the movable member 21 for locking or releasing the movable member 21 .

[0035] In this embodiment, a plurality of limiting grooves 112 are respectively provided on both sides of the support member 11 , and the plurality of limiting grooves 112 on each side of the support member 11 are respectively distributed at intervals along the length extension direction of the support member 11 .

[0036] In this embodiment, the locking member 3 is a bolt, which has a strong bearing capacity and is easy to disassemble and assemble, making it convenient for the locking member 3 to lock or loosen the movable member 21, thereby improving the working efficiency of the positioning device 200. It can be understood that in other embodiments, the locking member 3 can also be other structures, such as locking by screws and nuts.

[0037] In this embodiment, the support base 1 is made of metal material. The metal material is relatively stable, which ensures that the support base 1 will not be easily damaged, thereby increasing the service life of the support base 1. It can be understood that in other embodiments, the support base 1 can also be made of other materials, such as plastic.

[0038] In this embodiment, the two limiting members 12 are respectively connected to the two sides of the support member 11, so that the lower surface of the limiting member 12 and the limiting groove 112 are enclosed to form a groove, which reduces the thickness of the support member 11, thereby reducing the weight of the support member 11 and reducing the cost. It can be understood that in other embodiments, the groove can be directly opened on the support member 11 to increase the thickness of the support member 11.

[0039] The present embodiment is provided with a movable assembly 2 and a locking member 3, wherein the movable assembly 2 includes a movable member 21, and the locking member 3 is used to lock or loosen the movable member 21. When positioning the limit block 101 of the first set of jigs 100, the locking member 3 loosens the movable member 21, and the movable member 21 abuts against the limit block 101 of the first set of jigs 100, and then the locking member 3 locks the movable member 21, thereby obtaining the position of the limit block 101 of the first set of jigs 100. When the limit block 101 of the first set of jigs 100 is positioned, the movable member 21 is locked by the locking member 3. When the position of the first set of jigs 100 is copied to other jigs 100, the limit blocks 101 of the other jigs 100 are made to abut against the movable part 21 of the positioning device 200, and then the limit blocks 101 of the other jigs 100 are locked, so as to complete the copying of the size of the first set of jigs 100 to other jigs 100. The operation is simple, and there is no need to detect and adjust the size of the jigs 100, and batch copying is possible, which reduces the skill requirements and debugging time of biotechnical personnel, reduces costs, and improves work efficiency.

[0040] Continue to refer to Figure 4 and Figure 5 As shown, the movable member 21 also includes a connecting portion 210, which is movably disposed in the groove. The abutting portion 211 is connected to one end of the connecting portion 210 and is located outside the groove, and the length extension direction of the abutting portion 211 is perpendicular to the length extension direction of the connecting portion 210. The end of the abutting portion 211 away from the connecting portion 210 is provided with an abutting surface 211a, and the abutting surface 211a is used to abut against the limit block 101 of the fixture 100. The contact area between the abutting portion 211 and the limit block 101 of the fixture 100 is increased by the abutting of the abutting surface 211a, thereby ensuring the stability of the abutting surface 211a when abutting against the limit block 101 of the fixture 100.

[0041] The movable component 2 also includes an elastic member 22, one end of which is connected to one end of the connecting portion 210 away from the abutting portion 211, and the other end of the elastic member 22 is connected to the inner wall of the groove. The elastic member 22 is used to provide a driving force. Before the first set of jigs 100 are tested, the elastic member 22 is in a compressed state. When the first set of jigs 100 are tested, when the locking member 3 releases the movable member 21, the movable member 21 is moved in a direction close to the limit block 101 of the first set of jigs 100 by the elastic force of the elastic member 22, so that the abutting portion 211 abuts against the limit block 101 of the first set of jigs 100 to replicate the position of the limit block 101 of the first set of jigs 100.

[0042] The support member 11 is provided with a first connecting hole, the connecting part 210 is provided with a second connecting hole 210a, and the limiting member 12 is provided with a third connecting hole 120. The positions of the first connecting hole, the second connecting hole 210a, and the third connecting hole 120 are correspondingly arranged, and the locking member 3 is respectively passed through the first connecting hole, the second connecting hole 210a and the third connecting hole 120 for locking or releasing the movable member 21.

[0043] In this embodiment, the second connection hole 210a is configured as an elongated hole to facilitate locking of the movable member 21 after movement. It is understandable that in other embodiments, the first connection hole and the third connection hole 120 may also be configured as elongated holes.

[0044] In this embodiment, a plurality of movable members 21 are provided, each movable member 21 is disposed in each limiting groove 112 , and the number of movable members 21 corresponds to the number of limiting grooves 112 to respectively detect the positions of the plurality of limiting blocks 101 of the fixture 100 .

[0045] In this embodiment, the roughness Ra of the abutting surface 211 a ranges from 0.8 to 1.6, which prevents the surface roughness from being too small, thereby increasing the processing cost, and prevents the surface roughness from being too large, thereby affecting the positioning accuracy of the positioning device 200 .

[0046] In this embodiment, the connecting portion 210 and the abutting portion 211 are integrally formed to facilitate manufacturing. It is understandable that in other embodiments, the connecting portion 210 and the abutting portion 211 may also be separate structures.

[0047] In this embodiment, the elastic member 22 is a compression spring, which has high durability, thereby increasing the service life of the elastic member 22, and the compression spring has high reliability and stability, thereby ensuring the stability of the movement of the movable member 21 and improving the positioning accuracy of the positioning device. It can be understood that in other embodiments, the elastic member 22 can also be other parts made of elastic materials, such as rubber.

[0048] In this embodiment, the movable part 21 is made of metal material. The metal material has high strength and stability and can withstand greater pressure and tension, thereby ensuring that the movable part 21 is not easily deformed or damaged when squeezed by the elastic part 22 and the limit block 101, thereby improving the service life of the movable part 21. It can be understood that in other embodiments, the movable part 21 can also be made of other materials, such as plastic.

[0049] Reference Figure 3 , Figure 5 and Figure 6 As shown, the support member 11 further includes positioning portions 110, which are disposed at both ends of the support member 11. The fixture 100 includes positioning matching portions 102, and the positions and quantities of the positioning matching portions 102 are matched with the positions and quantities of the positioning portions 110.

[0050] When the positioning device 200 is placed on the fixture 100, the positioning portion 110 cooperates with the positioning matching portion 102 to position the positioning device 200, thereby ensuring that the position of the movable member 21 is set correspondingly to the position of the limit block 101 of the fixture 100. The body 104 is provided with a silicon steel sheet groove 103 for placing the silicon steel sheet to push the movable member 21 to move in a direction away from the limit block 101.

[0051] In this embodiment, the positioning portion 110 is configured as a protrusion, and the positioning matching portion 102 is configured as a positioning groove. It is understandable that in other embodiments, the positioning portion 110 may be configured as a positioning groove, and the positioning matching portion 102 may be configured as a protrusion.

[0052] In a specific application scenario, when positioning the limit block 101 of the first set of jigs 100, the positioning portion 110 is first matched with the positioning matching portion 102 to position the positioning device 200, and then the movable member 21 is released by the locking member 3. At this time, the movable member 21 is moved in a direction close to the limit block 101 of the first set of jigs 100 by the elastic member 22, so that the abutting portion 211 abuts against the limit block 101 of the first set of jigs 100, and then the movable member 21 is locked by the locking member 3 to copy the limit block 101 of the first set of jigs 100. 01; when copying the position of the limit block 101 of the first set of jigs 100 to other jigs 100, the positioning device 200 is placed in the other jigs 100 through the positioning portion 110 and the positioning matching portion 102, loosen the fastening screw 105 of the limit block 101 of the jig 100, and then insert the silicon steel sheet into the silicon steel sheet groove 103 of the jig 100, so that the limit block 101 of the jig 100 abuts against the abutment portion 211, and then lock the fastening screw 105 of the limit block 101 of the jig 100, thereby completing the size replication.

[0053] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application.
