Description

Technical Field

[0001] This utility model relates to the field of tooling equipment technology, specifically to a three-axis positioning tooling assembly. Background Technology

[0002] The magnetic circuit drives the moving contact assembly to move through electromagnetic force, thereby achieving mechanical opening or closing and completing the on / off control of the circuit. In the existing technology, the magnetic circuit and the moving contact assembly are installed manually by workers. Due to the long overall structure, the concentricity requirement between the magnetic circuit and the moving contact assembly is high. If the concentricity is not high, scratches will occur inside, and the product performance will be reduced. Manual installation cannot ensure the concentricity of the product, making it difficult to reduce the scrap rate of the product. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defect that manual installation in the prior art cannot ensure the concentricity of the product, which makes it difficult to reduce the scrap rate of the product. Thus, a three-axis positioning tooling assembly can be provided to effectively improve the concentricity between the magnetic circuit and the moving contact assembly.

[0004] Therefore, this utility model provides a three-axis positioning fixture assembly, including a base and a placement assembly disposed on the base. The placement assembly includes a first placement plate for placing a magnetic circuit and a second placement plate for placing a moving contact assembly. The magnetic circuit and the moving contact assembly are connected by a connecting shaft. A positioning plate capable of positioning the first and second placement plates is disposed around the placement assembly. The positioning plate is linked with the first and second placement plates. The positioning plate has an initial position and a positioning position that narrows from both sides toward the side closer to the first and second placement plates. When the positioning plate is in the positioning position, the axes of the magnetic circuit and the moving contact assembly are on the same horizontal straight line.

[0005] Furthermore: the first placement plate is provided with a first placement cavity for placing the magnetic circuit, and the second placement plate is provided with a second placement cavity for placing the moving contact assembly. The second placement plate includes a first limiting block and a second limiting block arranged opposite to each other. When the positioning plate moves horizontally, it can drive the first limiting block and the second limiting block to move from both sides toward the side closer to the magnetic circuit and the moving contact assembly. The positioning plate is provided with a guide groove to switch the positioning plate from the initial position to the positioning position.

[0006] Furthermore: the base is provided with a movable groove, and a movable block is provided below the positioning plate and inserted into the movable groove. A reset spring is connected to the side of the movable block and embedded in the movable groove. The movable block can move along the opening direction of the movable groove to switch the positioning plate from the initial position to the positioning position.

[0007] Furthermore, the positioning plate is also provided with a push plate, and the side of the push plate opposite to the magnetic circuit is provided with a plug that can be inserted into the magnetic circuit.

[0008] Furthermore: the first placement plate includes a base plate and a card plate disposed on the base plate. A clearance groove is provided between the base plate and the card plate for inserting a rod and extending into the magnetic circuit. Abutment blocks that abut against the magnetic circuit are provided around the card plate. Positioning holes are provided on the base plate and the card plate for external fastening nails to pass through and for positioning the two.

[0009] Furthermore, positioning posts are provided on the first and second limiting blocks.

[0010] Furthermore: the inner side of the second placement plate is provided with a stop block that can abut against the moving contact assembly. Furthermore: a locking structure is provided between the positioning plate and the base, the locking structure including a locking rod disposed on the base and a locking groove disposed on the positioning plate that can be adapted to the locking rod, and a pushing spring is provided below the locking rod for pushing the locking rod upward.

[0011] The technical solution of this utility model has the following advantages:

[0012] 1. The present invention provides a three-axis positioning fixture assembly. During the manufacturing process, the magnetic circuit is first placed in the first placement plate, and then the moving contact assembly is placed in the second placement plate. Next, a cover plate is placed on top of the first and second placement plates. Then, the positioning plate is pushed to the right, so that the positioning plate moves to drive the first and second placement plates to move from both sides to the middle to clamp the moving contact, so that the axes of the magnetic circuit and the moving contact can be on the same horizontal straight line. A linkage mechanism is set between the positioning plate and the second placement plate. The rightward movement of the positioning plate is used as a power to drive the second placement plate to tighten. After tightening, the connection position of the magnetic circuit and the moving contact assembly can be connected.

[0013] 2. This utility model provides a three-axis positioning fixture assembly. A first placement plate has a first placement cavity, which effectively fixes the position of the magnetic circuit. A second placement plate has a second placement cavity, which is used to fix the contact assembly. After the lateral position of the magnetic circuit and the contact assembly is inserted into the first and second placement cavities, it is necessary to fix the longitudinal position of the magnetic circuit and the contact assembly. Therefore, the positioning plate is pushed to the right. On the side of the first and second limiting blocks opposite to the guide groove, there is a rod that inserts into the guide groove. This rod extends... Inside the base, the guide groove has a positioning end and a moving end. When the positioning plate moves to the right, since the first and second limiting blocks are in a limited state, the insertion rod will move from the positioning end to the moving end position. This will drive the first and second limiting blocks to move from both sides to the side closer to the contact assembly. Since the first and second limiting blocks are made of a single steel plate, the distance the first and second limiting blocks move from both sides to the middle will be the same. This will ensure that the axis of the contact assembly and the axis of the magnetic circuit are on the same horizontal straight line. Attached Figure Description

[0027] Example

[0028] This embodiment provides a three-axis positioning fixture assembly, including a base 1 and a placement assembly 2 disposed on the base 1. The placement assembly 2 includes a first placement plate 21 for placing a magnetic circuit and a second placement plate 22 for placing a moving contact assembly. The magnetic circuit and the moving contact assembly are connected by a connecting shaft 3. The placement assembly 2 is surrounded by a positioning plate 23 capable of positioning the first placement plate 21 and the second placement plate 22. The positioning plate is linked with the first and second placement plates. The positioning plate 23 has an initial position and a positioning position that narrows from both sides toward the side closer to the first placement plate 21 and the second placement plate 22. When the positioning plate 23 is in the positioning position, the axes of the magnetic circuit and the moving contact assembly are on the same horizontal straight line.

[0029] The specific improvements mentioned above are as follows: Figures 1-3 As shown, during the manufacturing process, the magnetic circuit is first placed in the first placement plate 21, and then the moving contact assembly is placed in the second placement plate 22. Next, a cover plate is placed on top of the first placement plate 21 and the second placement plate 22. Then, the positioning plate 23 is pushed to the right, so that the positioning plate 23 moves to drive the first placement plate 21 and the second placement plate 22 to move from both sides to the middle to clamp the moving contact, so that the axis of the magnetic circuit and the moving contact can be on the same horizontal straight line. A linkage mechanism is set between the positioning plate 23 and the second placement plate 22. The rightward movement of the positioning plate 23 is used as power to drive the second placement plate 22 to tighten. After tightening, the connection position of the magnetic circuit and the moving contact assembly can be connected. The linkage mechanism can be driven by a drive shaft or by a guide groove 71. Those skilled in the art can choose an existing mechanical structure that can change the force according to the specific situation.

[0030] Based on the above embodiments: the first placement plate 21 is provided with a first placement cavity 24 for placing the magnetic circuit, the second placement plate 22 is provided with a second placement cavity 25 for placing the moving contact assembly, the second placement plate 22 includes a first limiting block 26 and a second limiting block 27 arranged opposite to each other, the positioning plate 23 is provided with a guide groove 71 for switching the positioning plate 23 from the initial position to the positioning position, when the positioning plate 23 moves horizontally, it can drive the first limiting block 26 and the second limiting block 27 to move from both sides toward the side closer to the magnetic circuit and the moving contact assembly, the positioning plate 23 is provided with a guide groove 71 for switching the positioning plate 23 from the initial position to the positioning position.

[0031] The specific improvements mentioned above are as follows: Figure 2 and Figure 3As shown, the first placement plate 21 has a first placement cavity 24, which effectively fixes the position of the magnetic circuit. The second placement plate 22 has a second placement cavity 25, which is used to fix the contact assembly. After the magnetic circuit and the contact assembly are inserted into the first and second placement cavities 24 and 25, it is necessary to fix the longitudinal position of the magnetic circuit and the contact assembly. Therefore, the positioning plate 23 is pushed to the right. The first limiting block 26 and the second limiting block 27 have a rod 51 that is inserted into the guide groove 71 on the side opposite to the guide groove 71. The rod 51 extends into the base 1. The guide groove 71 has... The device has a positioning end 711 and a moving end 712. When the positioning plate 23 moves to the right, the first limiting block 26 and the second limiting block 27 are in a limiting state, and its insertion rod 51 will move from the positioning end 711 to the moving end 712. This will drive the first limiting block 26 and the second limiting block 27 to move from both sides to the side closer to the contact assembly. Since the first limiting block 26 and the second limiting block 27 are made of a single steel plate, the distance that the first limiting block 26 and the second limiting block 27 move from both sides to the middle will be the same. This will ensure that the axis of the contact assembly and the axis of the magnetic circuit are on the same horizontal straight line.

[0032] Based on the above embodiments: a movable groove 4 is provided on the base 1, and a movable block 41 is provided below the positioning plate 23 and inserted into the movable groove 4. A reset spring 42 embedded in the movable groove 4 is connected to the side of the movable block 41. The movable block 41 can move along the opening direction of the movable groove 4 to switch the positioning plate 23 from the initial position to the positioning position.

[0033] The specific improvements mentioned above are as follows: Figures 4-6 As shown, a movable groove 4 is provided on the base 1, and a movable block 41 is provided on the positioning plate 23 that is inserted into the movable groove 4. A reset spring 42 is provided in the movable groove 4. One end of the reset spring 42 is fixedly connected to the movable block 41, and the other end is fixedly connected to the side wall of the movable groove 4. By setting the reset spring 42, the positioning plate 23 has an elastic restoring force, so that the positioning plate 23 can automatically reset after the magnetic circuit and contact assembly are installed.

[0034] Based on the above embodiments: the positioning plate 23 is further provided with a push plate 5, and the side of the push plate 5 opposite to the magnetic circuit is provided with a plug rod 51 that can be inserted into the magnetic circuit.

[0035] The specific improvements mentioned above are as follows: Figure 2 and Figure 3As shown, a push plate 5 is provided on the positioning plate 23. After the magnetic circuit is installed in the first placement cavity 24, the insertion rod 51 on the push plate 5 will be inserted into the magnetic circuit to ensure that the first shaft is fixed. Then the positioning plate 23 continues to move to the right, so that the first limit block 26 and the second limit block 27 move from both sides to the middle and clamp the contact assembly. Then the second shaft is connected at the connection between the magnetic circuit and the contact assembly. The contact assembly has a third shaft. Since the entire relay is relatively long, a high degree of concentricity needs to be ensured. If the concentricity is not high, scratches will occur inside the relay during use, which will reduce the performance of the product.

[0036] Based on the above embodiments: the first placement plate 21 includes a base plate 6 and a card plate 61 disposed on the base plate 6. A clearance groove 62 is provided between the base plate 6 and the card plate 61 for inserting the insertion rod 51 and extending into the magnetic circuit. Abutment blocks 63 that abut against the magnetic circuit are provided around the card plate 61. Positioning holes 64 are provided on the base plate 6 and the card plate 61 for external fastening nails to pass through and for positioning the two.

[0037] The specific improvements mentioned above are as follows: Figure 6 As shown, the first placement plate 21 includes a base plate 6 and a card plate 61 arranged vertically. The sides of the base plate 6 and the card plate 61 are provided with clearance grooves 62 for inserting the insertion rod 51 into the magnetic circuit. In order to further improve the positioning accuracy of the magnetic circuit, abutment blocks 63 are provided around the card plate 61, and positioning holes 64 are provided at the base plate 6 and the card plate 61, and fastening pins are passed through the positioning holes 64.

[0038] Based on the above embodiments: positioning posts 7 are provided on the first limiting block 26 and the second limiting block 27.

[0039] The specific improvements mentioned above are as follows: Figure 3 As shown, positioning posts 7 are provided on the first limiting block 26 and the second limiting block 27. The positioning posts 7 are connected to the base plate. Thus, when the positioning plate 23 moves to the right, it can drive the first limiting block 26 and the second limiting block 27 to tighten and clamp the contact assembly.

[0040] Based on the above embodiments: the inner side of the second placement plate 22 is provided with a stop block 8 that can abut against the moving contact assembly.

[0041] The specific improvements mentioned above are as follows: Figure 2 and Figure 3 As shown, a stop block 8 is provided at the second placement plate 22. With the setting of the stop block 8, when the first limiting block 26 and the second limiting block 27 move from both sides toward the middle, the stop block 8 can abut against the side wall of the contact assembly, thereby positioning the position of the contact assembly.

[0042] Based on the above embodiments: a locking structure 9 is provided between the positioning plate 23 and the base 1. The locking structure 9 includes a locking rod 91 provided on the base 1 and a locking groove 92 provided on the positioning plate 23 that can be adapted to the locking rod 91. A push spring 93 is provided below the locking rod 91 to push the locking rod 91 upward.

[0043] The specific improvements mentioned above are as follows: Figure 2 and Figure 3 As shown, a locking structure 9 is provided between the positioning plate 23 and the base 1. The locking structure 9 includes a locking rod 91 and a locking groove 92. The locking rod 91 is arranged in an "L" shape. When the positioning plate 23 is in the initial position, the lower end of the locking rod 91 is locked under the positioning plate 23, and the push spring 93 is in a compressed state. When the positioning plate 23 moves to the right to the set position, the locking rod 91 loses the limitation of the positioning plate 23, and the push spring 93 will release the elastic force, thereby locking into the locking groove 92 and positioning the positioning plate 23. When it is necessary to return the positioning plate 23 to the initial position, press the locking rod 91 down by hand, and then the positioning plate 23 will return to the initial position due to the elastic restoring force of the return spring 42.

[0044] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
