Description

Technical Field

[0001] This application relates to the field of relay processing technology, and in particular to relay bending fixtures. Background Technology

[0002] Relays, as automatic control electrical devices, are widely used in many fields such as power systems, industrial automation, and smart homes. They switch circuits on and off by controlling the opening and closing of contacts through electromagnetic force. Among them, the normally open pin is the key part of the relay, which is open in the initial state and closes under specific conditions to connect the circuit. Its molding precision directly affects the performance of the relay.

[0003] In current production practices, bending the normally open pins of relays largely relies on manual operation. Workers use specialized bending tools, such as needle-nose pliers or specially designed small bending jigs, and bend the normally open pins based on visual observation and long-accumulated experience.

[0004] Regarding the aforementioned technologies, the inventors believe that manual bending with the open foot is greatly affected by subjective factors. Different workers have varying skill levels, physical condition, and concentration. Even experienced workers inevitably experience fatigue after working for a long time, leading to fluctuations in bending accuracy and making it difficult to guarantee the consistency of batch products. Utility Model Content

[0005] The purpose of this application is to provide a relay bending fixture to improve the problem that it is difficult to ensure the consistency of batch products when manually bending normally open pins.

[0006] This application provides a relay bending fixture, which adopts the following technical solution:

[0007] A relay bending fixture includes a workbench and a relay. A placement plate is provided on the top surface of the workbench, and a positioning plate is fixedly provided on the placement plate. The positioning plate has a positioning groove for engaging and fixing the relay. The relay is provided with a normally open leg for manual pre-bending. A driving component is provided above the positioning plate, and a pressing component for bending the normally open leg is provided at the output end of the driving component.

[0008] By adopting the above technical solution, the positioning slot on the positioning plate can engage and fix the relay, which helps to place the relay accurately, reduces the fluctuation of bending accuracy caused by position deviation, and helps to improve the consistency of batch products. By setting up driving components and pressing components, mechanical power is used to replace manual bending, which reduces the impact of differences in the skill level, physical condition and concentration of different workers, making the bending process more stable and accurate.

[0009] Optionally, the output end of the drive component is provided with a clamping seat, and a rod is provided inside the clamping seat, with the pressing component rotatably sleeved on the rod.

[0010] By adopting the above technical solution, the pressure component is rotatably sleeved on the insert rod. During the bending process, it can rotate flexibly according to the actual situation of the normally open foot, better fit the normally open foot for bending, which helps to achieve the preset bending angle and improve the bending accuracy consistency of batch products. The clamping seat provides stable support for the insert rod and the pressure component, ensuring that the power of the driving component can be accurately transmitted to the pressure component.

[0011] Optionally, the clamping seat has insertion holes on both sides for inserting the insertion rod.

[0012] By adopting the above technical solution, the insertion rod is inserted into the clamping seat through the insertion hole, which facilitates installation, disassembly and replacement; the insertion hole provides precise positioning for the insertion rod, so that the insertion rod is installed in the correct position each time, thereby ensuring the positional accuracy of the pressing part, improving bending accuracy and product consistency.

[0013] Optionally, one end of the insertion rod is provided with a limiting plate that abuts against the outer wall of the clamping seat.

[0014] By adopting the above technical solution, the limiting plate can prevent the insertion rod from passing through the insertion hole of the clamping seat during operation, ensuring that the installation depth and position of the insertion rod meet the requirements.

[0015] Optionally, the positioning groove is provided through, and the placement plate has several receiving holes for accommodating the metal feet of the relay.

[0016] By adopting the above technical solution, the positioning groove is set through, and together with the receiving hole on the placement plate to accommodate the metal foot of the relay, the relay can be stably positioned in all directions; at the same time, it helps to protect the technical foot and reduce unnecessary losses caused by damage to the metal foot.

[0017] Optionally, the positioning plate is provided with an opening slot at the end of the positioning groove near the driving component to facilitate the placement of a relay.

[0018] By adopting the above technical solution, the open slot makes it easier for workers to quickly place the relay into the positioning slot, reducing the time and difficulty of placing the relay and improving operational efficiency. In mass production, it enables workers to complete their work more efficiently. The open slot can guide the relay smoothly into the positioning slot, reducing collisions and friction between the relay and the positioning plate, and reducing the risk of relay damage.

[0019] Optionally, the positioning plate is provided with a plurality of fixing bolts, and the positioning plate is fixed to the placement plate by the fixing bolts.

[0020] By adopting the above technical solution, the fixing bolts firmly fix the positioning plate to the placement plate, reducing the displacement or shaking of the positioning plate during the working process, which helps to reduce bending errors caused by the instability of the positioning plate and improve the consistency of batch products; the fixing bolt connection facilitates the adjustment and replacement of the positioning plate, ensuring that the tooling is always in good working condition.

[0021] Optionally, the fixing bolts are located diagonally on the positioning plate.

[0022] By adopting the above technical solution, the diagonally arranged fixing bolts make the positioning plate more evenly stressed during the fixing process, avoiding deformation or loosening of the positioning plate due to uneven stress. The even stress ensures the stability and accuracy of the positioning plate; at the same time, it facilitates the installation and fixing of the placement plate and improves the installation efficiency of the installation plate.

[0023] In summary, this application includes at least the following beneficial technical effects of the relay bending fixture:

[0024] 1. The positioning slots on the positioning plate can engage and fix the relay, which helps to place the relay accurately, reduces the fluctuation of bending accuracy caused by position deviation, and helps to improve the consistency of batch products; by setting up driving parts and pressing parts, mechanical power is used to replace manual bending, which reduces the impact of differences in the skill level, physical condition and concentration of different workers, making the bending process more stable and accurate.

[0025] 2. The pressure component is rotatably sleeved on the insert rod. During the bending process, it can rotate flexibly according to the actual situation of the normally open foot, better fit the normally open foot for bending, which helps to achieve the preset bending angle and improve the bending accuracy consistency of batch products; the clamping seat provides stable support for the insert rod and the pressure component, ensuring that the power of the drive component can be accurately transmitted to the pressure component;

[0026] 3. The open slot makes it easier for workers to quickly place the relay into the positioning slot, reducing the time and difficulty of placing the relay and improving operational efficiency. In mass production, it enables workers to complete their work more efficiently. The open slot can guide the relay smoothly into the positioning slot, reducing collisions and friction between the relay and the positioning plate, and reducing the risk of relay damage.

[0031] Relay bending fixture, refer to Figure 1 The fixture includes a workbench 1 and a relay 2. The workbench 1 serves as the basic support component of the entire fixture, providing a platform for the installation and operation of other components. A placement plate 3 is provided on the top surface of the workbench 1. The placement plate 3 is fixed to the workbench 1 by bolts, which are evenly distributed along the edge of the placement plate 3. The placement plate 3 is used to support the positioning plate 4 and the relay 2.

[0032] Reference Figure 1 The placement plate 3 is fixedly provided with a positioning plate 4, and the positioning plate 4 is provided with a number of fixing bolts 6. In this embodiment, two bolts are preferred. The positioning plate 4 is fixed to the placement plate 3 by fixing bolts 6, and the fixing bolts 6 are located diagonally on the positioning plate 4.

[0033] Reference Figure 2 The positioning plate 4 has a positioning groove 41 for engaging and fixing the relay 2. The positioning groove 41 is precisely machined according to the outer dimensions of the relay 2. The positioning groove 41 is through-hole, and its through-hole direction is consistent with the placement direction of the relay 2, making it convenient for workers to observe the placement of the relay 2 from the top and bottom of the positioning plate 4. The placement plate 3 has several receiving holes 31 for accommodating the metal feet of the relay 2. The positions of the receiving holes 31 correspond one-to-one with the distribution positions of the metal feet of the relay 2, and the diameter of the holes is slightly larger than the diameter of the metal feet. When the relay 2 is placed in the positioning groove 41, the metal feet can be smoothly inserted into the receiving holes 31.

[0034] Reference Figure 1 , Figure 2 The positioning plate 4 is located in the positioning groove 41 near the drive component 5 and has an opening groove 42 for placing the relay 2. The opening groove 42 and the positioning groove 41 are integrally formed, and the width of the opening groove 42 is greater than the width of the relay 2.

[0035] Reference Figure 1 The relay 2 is equipped with a normally open foot 21 for manual pre-bending. Manual pre-bending is a preliminary treatment before using this fixture for precise bending, preparing for subsequent bending operations. A drive component 5 is provided above the positioning plate 4. The drive component 5 is a cylinder, which is fixed to a specially provided bracket on the worktable 1 by bolts (the bracket is not shown in detail in the figure).

[0036] Reference Figure 3The output end of the drive component 5 is provided with a clamping seat 51, which is connected to the clamping seat 51 by welding. The clamping seat 51 has insertion holes 512 on both sides. A rod 511 is inserted into the clamping seat 51 through the insertion holes 512. The rod 511 and the insertion hole 512 are precisely fitted, allowing the rod 511 to be inserted and removed within the insertion hole 512 with a certain degree of stability. One end of the rod 511 is provided with a limiting plate 513 that abuts against the outer wall of the clamping seat 51. The limiting plate 513 and the rod 511 are an integral structure, and the diameter of the limiting plate 513 is larger than the diameter of the insertion hole 512.

[0037] Reference Figure 1 , Figure 3 The output end of the drive unit 5 is provided with a pressing member 52 that bends the normally open foot 21. The pressing member 52 is rotatably sleeved on the insertion rod 511, and the pressing member 52 and the insertion rod 511 are connected by a rolling connection. When the drive unit 5 pushes the clamping seat 51 and the pressing member 52 downward, the pressing member 52 contacts the normally open foot 21 on the relay 2, and the pressing member 52 rolls along the length of the normally open foot 21. During the bending process, the pressing member 52 can rotate around the insertion rod 511 according to the shape of the normally open foot 21 and the force applied.

[0038] The implementation principle of this application embodiment is as follows:

[0039] In actual use, assemble all components as required, and use the diagonally arranged fixing bolts 6 to install the positioning plate 4 on the placement plate 3. Check whether the drive component 5 and related components are normal. The worker puts the relay 2 with the pre-bent normally open foot 21 into the positioning groove 41 from the opening groove 42, and inserts the metal foot into the receiving hole 31 to avoid damage. Start the drive component 5, and its output end pushes the clamping seat 51 and the pressing part 52 to move downward. After the pressing part 52 contacts the normally open foot 21, it fits the surface of the normally open foot 21 by flexibly rotating around the insertion rod 511. The drive component 5 continuously applies pressure to bend the normally open foot 21 to the preset angle. During this period, the clamping seat 51 ensures stable force transmission. After bending is completed, the worker takes out the bent relay 2, and the drive component 5 reverses its movement to drive the components to reset, preparing for the next operation. This fixture avoids the influence of subjective human factors through automatic mechanical bending. The positioning groove 41 makes the relay 2 placed in a consistent position, which helps the consistency of batch products and improves the bending accuracy and quality of the normally open foot 21.

Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
