Description

Technical Field

[0001] This invention relates to the field of relay technology, and more specifically to a relay coil pin assembly bending fixture. Background Technology

[0002] A relay is an electronic control component that plays a role in automatic adjustment, safety protection, and circuit switching in circuits. It is widely used in power protection, automation, measurement and communication, and other fields. Due to the needs of technological development, relays are required to have a more compact structure, smaller size, higher sensitivity, and higher reliability.

[0003] A relay consists of a relay body, a coil mounted on the relay body, and multiple pins. The leads at both ends of the coil need to be connected to two corresponding pins. Currently, in the automated production of relays, the pins are first inserted into the relay body at an insertion station by an insertion mechanism, and then transferred to a bending station where a bending mechanism bends the pins. Because the pins need to go through two processes, insertion and bending, the production speed is relatively slow, increasing production costs. In addition, the insertion and bending mechanisms occupy a large amount of space. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects of slow pin production speed and high production cost in the prior art, thereby providing a relay coil pin assembly bending fixture with fast production speed.

[0005] To this end, the present invention provides a relay coil pin assembly bending fixture, comprising a first actuating element, a bending assembly, and a driving mechanism. The first actuating element is movably mounted on a worktable and is adapted to drive the pin to be inserted into the relay body. The bending assembly is movably mounted on the worktable and is adapted to bend the pin. The driving mechanism includes a driving block adapted to drive the first actuating element to perform an insertion action and drive the bending assembly to perform a bending action.

[0006] The bending assembly includes a bending component and a second actuating component. The bending component is rotatably mounted on the worktable. The second actuating component is movably mounted on the worktable and is driven by the driving block to drive the bending component to perform a bending action.

[0007] The second actuator is positioned below the first actuator, and the driving block has an initial position above the first actuator, as well as an insertion position and a bending position that move downwards and sequentially drive the first actuator and the second actuator.

[0008] Both the first and second actuators move horizontally, while the drive block moves vertically. A steering engagement structure is provided between the drive block and both the first and second actuators, which is adapted to convert the vertical movement of the drive block into the horizontal movement of the first and second actuators.

[0009] The steering engagement structure includes a first inclined surface located below the drive block, and a second and a third inclined surface located on the first and second actuators respectively, corresponding to and engaging with the first inclined surface.

[0010] The drive block has a blocking surface that abuts against the side of the first inclined surface, wherein when the blocking surface abuts against the side of the first actuator, the first actuator remains in the insertion position.

[0011] The bending member has a rotating arm that corresponds to and abuts against the second actuating member, and a driving arm adapted to drive the pin bending.

[0012] The workbench is also provided with a first elastic element and a second elastic element, which are suitable for resetting the first actuator and the second actuator respectively.

[0013] The workbench is provided with a fixture suitable for installing the relay body, and the drive mechanism includes a pressure block assembly located above the fixture.

[0014] The driving mechanism includes a mounting plate and a pressure block assembly. The mounting plate is fixedly mounted with the driving block and the pressure block assembly. The mounting plate is provided with a receiving groove suitable for mounting the pressure block assembly. A pin is fixedly mounted on the side wall of the receiving groove. The pressure block assembly includes a pressure block and a third elastic member. The pressure block is formed with an elongated hole that is vertically arranged and allows the pin to pass through. One end of the third elastic member abuts against the bottom wall of the receiving groove, and the other end abuts against the pressure block.

[0015] The technical solution of this invention has the following advantages:

[0016] 1. The relay coil pin assembly bending fixture provided by the present invention includes a first actuating element, a bending assembly, and a driving mechanism. Since the insertion action of the first actuating element and the bending action of the bending assembly are both driven by the same driving block, compared with the prior art, this eliminates the transfer process between the insertion and bending processes, making the processing faster and more convenient, improving production efficiency, and reducing production costs. In addition, the entire fixture structure is simpler and occupies less space.

[0017] 2. The relay coil pin assembly bending fixture provided by the present invention has the advantage of simple structure because the first actuating member pushes part of the pin into the relay body, while the bending member bends the part of the pin inserted into the relay body. That is, the bending member and the first actuating member are in different positions. The driving block drives the second actuating member to drive the bending member to perform the bending action, so that the insertion and bending are driven by the same driving block.

[0018] 3. The relay coil pin assembly bending fixture provided by the present invention has a second actuating component located below the first actuating component. The driving block has an initial position located above the first actuating component, as well as an insertion position and a bending position that move downwards and sequentially drive the first and second actuating components to move. This makes the processing quick and convenient and improves production efficiency.

[0019] 4. The relay coil pin assembly bending fixture provided by the present invention includes a first inclined surface located below the drive block, and a second inclined surface and a third inclined surface located on the first and second actuators respectively, which cooperate with the first inclined surface. When the drive block moves downward, the first inclined surface cooperates with the second and third inclined surfaces respectively, thereby driving the first and second actuators to move laterally. The above-mentioned steering cooperation structure has the advantage of simple structure.

[0020] 5. The relay coil pin assembly bending fixture provided by the present invention has a driving block having a blocking surface that abuts against the side of the first inclined surface. When the blocking surface abuts against the side of the first actuating member, the first actuating member remains in the insertion position. In this way, when the driving block continues to move downward and drives the bending assembly to perform the bending action, it can ensure that the position of the pin relative to the relay body will not shift, thereby improving the assembly reliability.

[0021] 6. The relay coil pin assembly bending fixture provided by the present invention includes a driving mechanism comprising: a mounting plate on which a driving block and a pressing block assembly are fixedly mounted; the mounting plate having a receiving groove suitable for mounting the pressing block assembly, and a pin fixedly mounted on the side wall of the receiving groove; and a pressing block assembly comprising a pressing block and a third elastic member; the pressing block having a vertically oriented elongated hole through which the pin passes; one end of the third elastic member abutting against the bottom wall of the receiving groove, and the other end abutting against the pressing block. By providing the elongated hole, the mounting plate can move relative to the pressing block. Thus, after the pressing block presses against the relay body, the driving block can continue to drive the first actuating member and the bending assembly downwards under the influence of the mounting plate. Compared with the prior art, which requires two separate cylinders to drive the pressing block assembly and the driving block, the structure is simpler and production costs are reduced.

[0035] Example

[0036] This embodiment provides a relay coil pin assembly bending fixture, suitable for bending relay coil pins as follows: Figure 1 Pin 3, as shown, is inserted into the relay body 4 and bent, as... Figure 2 As shown, it includes a worktable 2, a first action component 1, a bending assembly 5, and a drive mechanism.

[0037] Workbench 2, such as Figure 7 As shown, it is provided with a clamp 10 suitable for the relay body 4, and a pin mounting base 25 suitable for placing the pin 3. The pin mounting base 25 is formed with a mounting groove for placing the pin 3.

[0038] The first actuating element 1 is movably mounted on the worktable 2 via the first elastic element 16, such as... Figure 3 As shown, the bottom of the first actuating member 1 is formed with a push block that extends into the mounting groove and is suitable for driving the pin 3 to be inserted into the relay body 4. One end of the first elastic member 16 abuts against the first actuating member 1, and the other end abuts against the worktable 2.

[0039] The bending assembly 5 is movably mounted on the worktable 2 and is adapted to bend the pin 3. Figure 3 and 4As shown, the bending assembly 5 includes: a bending member 7, rotatably mounted on the worktable 2, the bending member 7 having a rotating arm 14 corresponding to and abutting the second actuating member 8, and a driving arm 15 adapted to drive the pin 3 to bend; and a second actuating member 8, movably mounted on the worktable 2 via a second elastic member 17, the second actuating member 8 being driven by the driving block 6 to drive the bending member 7 to perform a bending action, the second actuating member 8 being located below the first actuating member 1, both moving in the horizontal direction. It should be noted that the worktable 2 also has a torsion spring (not shown in the figure) adapted to drive the bending member 7 to reset.

[0040] The drive mechanism includes a mounting plate 19, a pressure block assembly 18, and a drive block 6.

[0041] Mounting plate 19, on which the drive block 6 and the pressure block assembly 18 are fixedly mounted, such as Figure 5 and 6 As shown, the mounting plate 19 is provided with a receiving groove 20 suitable for installing the pressure block assembly 18, and a pin 21 is fixedly installed on the side wall of the receiving groove 20. The pressure block assembly 18 is located above the clamp 10 and includes a pressure block 22 and a third elastic member 23. The pressure block 22 is formed with an elongated hole 24 that is vertically arranged and allows the pin 21 to pass through. One end of the third elastic member 23 abuts against the bottom wall of the receiving groove 20, and the other end abuts against the pressure block 22.

[0042] The driving block 6 is adapted to drive the first actuating member 1 to perform an insertion action and drive the bending assembly 5 to perform a bending action. The driving block 6 has an initial position above the first actuating member 1, and an insertion position and a bending position that move downwards and sequentially drive the first actuating member 1 and the second actuating member 8. The driving block 6 moves vertically, and a steering engagement structure is provided between the driving block 6 and both the first actuating member 1 and the second actuating member 8. The steering engagement structure is adapted to convert the vertical movement of the driving block 6 into horizontal movement of the first actuating member 1 and the second actuating member 8. Figure 3 As shown, the steering engagement structure includes a first inclined surface 11 disposed below the drive block 6, and a second inclined surface 12 and a third inclined surface 13 disposed on the first actuating member 1 and the second actuating member 8, respectively, and correspondingly engaging with the first inclined surface 11. The drive block 6 has a blocking surface 9 that abuts against the side of the first inclined surface 11, wherein when the blocking surface 9 abuts against the side of the first actuating member 1, the first actuating member 1 remains in the insertion position.

[0043] As an alternative implementation, the first inclined surface 11 may be provided only in the drive block 6, or only in the first actuator 1 and the second actuator 8.

[0044] The working principle of the relay coil pin assembly bending fixture of the present invention is as follows:

[0045] The drive mechanism first moves downward, causing the pressure block 22 to press against the relay body 4. Then, the drive block 6 continues to move downward. The first inclined surface 11 of the drive block 6 cooperates with the second inclined surface 12 of the first actuating member 1, thereby driving the first actuating member 1 to move to the left. The push block of the first actuating member 1 inserts the pin 3 into the relay body 4. After the pin is inserted, the drive block 6 continues to move downward. At this time, the blocking surface 9 of the drive block 6 abuts against the side of the first actuating member 1, keeping the first actuating member 1 in the insertion position (i.e., it will not continue to move to the left). The first inclined surface 11 of the drive block 6 cooperates with the third inclined surface 13 of the second actuating member 8, thereby driving the second actuating member 8 to move to the left. The second actuating member 8 abuts against the rotating arm 14 of the bending member 7, causing the rotating arm 14 to rotate clockwise. The drive arm 15 of the bending member 7 drives the pin 3 to bend.

[0046] The relay coil pin assembly bending fixture provided by the present invention includes a first actuating element 1, a bending component 5, and a driving mechanism. Since the insertion action of the first actuating element 1 and the bending action of the bending component 5 are both driven by the same driving block 6, compared with the prior art, this eliminates the transfer process between the insertion and bending processes, making the processing faster and more convenient, improving production efficiency, and reducing production costs. In addition, the entire fixture structure is simpler and occupies less space.

[0047] 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 scope of protection of this invention.
