However, in order to ensure that the positioning cylinder can be inserted into the inner hole of the cylindrical core, a certain clearance needs to be left when the positioning cylinder and the inner hole of the cylindrical core are fitted. This may cause the axes of the positioning cylinder and the cylindrical core to not coincide, affecting the positioning accuracy. Utility Model Content

[0021] This utility model proposes a relay processing positioning device and a relay assembly equipment. The relay processing positioning device includes a positioning assembly and a driving mechanism. It comprises a positioning cylinder and a movable rod, the movable rod being movably inserted through the positioning cylinder and coaxially arranged with it. The positioning cylinder has a positioning ring, a portion of which abuts against the outer peripheral wall of the movable rod.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

If the specific posture changes, the directional indicators will also change accordingly.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions.

[0038] In relay design, it is typically necessary to connect the first iron frame 210 and the second iron frame 220 together, ensuring that the first iron frame 210, the second iron frame 220, and the plastic cylindrical core 230 used to mount the coil are coaxially aligned. In related technologies, a positioning cylinder 11 is usually inserted into the inner hole 230a of the plastic cylindrical core 230 to ensure coaxiality. However, to ensure that the positioning cylinder 11 can be inserted into the inner hole 230a of the cylindrical core 230, a certain clearance is required when the positioning cylinder 11 mates with the inner hole 230a of the cylindrical core 230. This may cause the axes of the positioning cylinder 11 and the cylindrical core 230 to not coincide, affecting positioning accuracy. In addition, the equipment will fix the first iron frame 210, that is, the iron frame located above, while the second iron frame 220 and the cylindrical core 230 located on the second iron frame 220 can move relative to the first iron frame 210. Since there is a certain fit tolerance between the outer diameter of the positioning cylinder 11 and the inner diameter of the inner hole 230a of the cylindrical core 230, the coaxiality of the first iron frame 210 and the cylindrical core 230 cannot be guaranteed.

[0039] To address the aforementioned problems, this utility model proposes a relay processing positioning device 100, aiming to provide a relay processing positioning device 100 that can further improve the positioning accuracy of the cylindrical core 230, the first iron frame 210, and the second iron frame 220. Figures 1 to 8 This is a schematic diagram of one embodiment of the relay processing and positioning device 100 of this utility model.

[0040] Please refer to Figures 1 to 8This utility model proposes a relay processing positioning device 100, including a positioning component 1 and a driving mechanism 2. The positioning component 1 includes a positioning cylinder 11 and a movable rod 12. The movable rod 12 is movably inserted through the positioning cylinder 11 and coaxially arranged with the positioning cylinder 11. The positioning cylinder 11 is provided with a positioning ring 13. Part of the structure of the positioning ring 13 abuts against the outer peripheral wall of the movable rod 12. The side of the positioning ring 13 facing away from the movable rod 12 is exposed on the outside of the positioning cylinder 11. The driving mechanism 2 has a movable end 211, which is connected to one end of the movable rod 12 and is used to drive the movable rod 12 to move relative to the positioning cylinder 11.

[0041] During the relay positioning process, the first iron frame 210 and the second iron frame 220 are pre-assembled, and there is still a certain movable gap between them. The pre-assembled first iron frame 210 and the second iron frame 220 are installed on the fixture seat of the relay assembly equipment. The fixture seat will fix the first iron frame 210, while the second iron frame 220 can still move relative to the first iron frame 210. After that, the driving component on the equipment drives the relay processing positioning device 100 to move downward until the positioning cylinder 11 on the positioning component 1 passes through the first iron frame 210 and is inserted into the inner hole 230a of the cylindrical core 230. At this time, the coarse positioning of the first iron frame 210 and the cylindrical core 230 is achieved, and the positions of the first iron frame 210, the cylindrical core 230 and the second iron frame 220 are adjusted, and the three tend to be coaxial. Furthermore, the drive mechanism 2 drives the movable rod 12 to move downward until the movable rod 12 abuts against the inner contact surface 131 of the positioning ring 13, thereby driving the positioning ring 13 to move radially along the positioning cylinder 11. Since the outer contact surface 132 of the positioning ring 13 is tightly fitted with the inner wall of the inner hole 230a of the cylindrical core 230, under the drive of the movable rod 12, the positioning ring 13 drives the cylindrical core 230 and the second iron frame 220 to move to the preset assembly position, ensuring that the coaxiality between the first iron frame 210 and the cylindrical core 230 meets the product requirements.

[0042] The present invention provides a relay processing positioning device 100 and a relay assembly equipment. The relay processing positioning device 100 includes a positioning component 1 and a driving mechanism 2. It includes a positioning cylinder 11 and a movable rod 12. The movable rod 12 is movably inserted through the positioning cylinder 11 and coaxially arranged with the positioning cylinder 11. The positioning cylinder 11 is provided with a positioning ring 13. Part of the structure of the positioning ring 13 abuts against the outer peripheral wall of the movable rod 12. The side of the positioning ring 13 facing away from the movable rod 12 is exposed on the outside of the positioning cylinder 11. The driving mechanism 2 is used to drive the movable rod 12 to move inside the positioning cylinder 11. During the positioning operation of the two iron frames of the relay, the positioning cylinder 11 is inserted into the holes of the iron frame and the cylindrical core 230 respectively, so that the iron frame and the cylindrical core 230 are coarsely positioned. When the positioning cylinder 11 is in place, the drive mechanism 2 drives the movable rod 12 to move downward until the movable rod 12 abuts against the inner side wall of the positioning ring 13, so that the positioning ring 13 moves radially along the positioning cylinder 11. Since the outer peripheral wall of the positioning ring 13 is in contact with the inner peripheral wall of the hole of the cylindrical core 230, the movement of the positioning ring 13 will drive the cylindrical core 230 to move, thereby achieving secondary positioning, further improving the fitting accuracy of the iron frame and the cylindrical core 230, and ensuring that their coaxiality meets the corresponding requirements.

[0043] In the technical solution of this utility model, the product can be repositioned. For details, please refer to further documentation. Figure 3 The positioning cylinder 11 has a circumferential groove 11b, which is connected to the axial channel 11a of the positioning cylinder 11. The positioning ring 13 is movably disposed within the groove 11b. This structure embeds the positioning ring 13 into the groove 11b, allowing it to move radially within the groove while maintaining contact with the outer peripheral wall of the movable rod 12. Its working principle is that when the drive mechanism 2 moves the movable rod 12 downwards, the movable rod 12 abuts against the inner wall of the positioning ring 13, pushing the positioning ring 13 outwards along the groove 11b. This causes the outer peripheral wall of the positioning ring 13 to fit tightly against the inner peripheral wall of the cylindrical core 230 hole, achieving precise positioning of the cylindrical core 230. By setting the groove 11b and the movable positioning ring 13, secondary positioning can be performed on top of coarse positioning, further improving positioning accuracy. The advantage is a significant improvement in the fit accuracy between the iron frame and the cylindrical core 230, ensuring that the coaxiality of the three meets higher standards, thereby improving the overall performance and reliability of the relay.

[0044] After the drive mechanism 2 drives the movable rod 12 to descend, the movable rod 12 needs to be reset so that subsequent repeatable operations can be performed. Therefore, an annular boss 121 is provided at the end of the movable rod 12 away from the positioning ring 13. This boss is located outside the channel 11a of the positioning cylinder 11. The positioning assembly 1 also includes a reset member 14 sleeved on the movable rod 12, with its two ends abutting against the annular boss 121 and the positioning cylinder 11, respectively. For details, please refer to further reference. Figure 2 and Figure 3 The elastic force of the reset element 14 allows the movable rod 12 to automatically return to its initial position after completing the positioning operation, preparing it for the next positioning operation. This improves the repeatability and consistency of positioning operations, ensures accuracy in each positioning, reduces manual intervention, and increases production efficiency. Furthermore, the reset element 14 provides cushioning during the movement of the movable rod 12, reducing equipment wear and extending its service life, thereby improving product quality while reducing maintenance costs.

[0045] It should be noted that the reset element 14 can be a spring or an elastic silicone sleeve; this application does not limit this. In one embodiment of this application, the reset element 14 is a spring. The spring can provide reliable elastic support when the movable rod 12 moves and quickly restore the movable rod 12 to its initial position after the drive mechanism 2 retracts, ensuring the repeatability and consistency of the positioning operation. The spring has a simple structure, low cost, and high durability, and can maintain stable performance in frequent use, reducing equipment maintenance costs and failure rates, thereby improving the reliability and service life of the relay processing positioning device 100.

[0046] This application proposes two driving methods; please refer to the relevant documentation for details. Figure 3 In the first embodiment of this application, the drive mechanism 2 includes a cylinder 21 and an abutment member 22. The extension and retraction direction of the cylinder 21 is perpendicular to the axial direction of the positioning cylinder 11. When the cylinder 21 extends and retracts, the abutment member 22 at the movable end 211 also moves accordingly, driving the movable rod 12 to rise and fall. Specifically, the abutment surface 221 of the abutment member 22 includes a first straight surface 2211, an inclined surface 2212, and a second straight surface 2213 connected in sequence. When the movable end 211 of the cylinder 21 extends, the first straight surface 2211 of the abutment member 22 first contacts the end of the movable rod 12. As the cylinder 21 continues to push, the inclined surface 2212 gradually guides the movable rod 12 to move downward. Finally, the second straight surface 2213 abuts against the movable rod 12, completing the positioning action of the movable rod 12. This design, through the transition effect of the inclined plane 2212, enables the smooth and gradual movement of the movable rod 12, avoiding uneven force or damage to the movable rod 12 caused by direct hard contact, thereby improving the positioning accuracy and reliability, reducing equipment wear, extending service life, and enhancing the overall performance and stability of the relay processing positioning device 100.

[0047] In the first embodiment, to reduce the frictional resistance between the abutment 22 and the movable rod 12, a rolling element 15 is provided at the end of the movable rod 12 near the abutment 22, and it rolls against the abutment surface 221. This design can significantly reduce the frictional force between the movable rod 12 and the abutment 22. When the rolling element 15 rolls on the abutment surface 221 (including the first straight surface 2211, the inclined surface 2212, and the second straight surface 2213), it can guide the movable rod 12 to move more smoothly and steadily, avoiding wear and jamming problems caused by sliding friction. This rolling contact method not only improves the flexibility and accuracy of the movement of the movable rod 12, but also extends the service life of the movable rod 12 and the abutment 22, further improving the reliability and stability of the entire relay processing positioning device 100, and ensuring the efficient and accurate completion of the positioning operation.

[0048] In the second embodiment of this application, specifically, please refer to further details. Figure 4 The second embodiment differs from the first embodiment in that the design of the abutment member 22 is eliminated, the extension and retraction direction of the cylinder 21 coincides with the axial direction of the positioning cylinder 11, and the movable end 211 of the cylinder 21 is connected to the movable rod 12. The movable rod 12 can be driven to move directly by the extension and retraction of the cylinder 21, which further simplifies the overall structure of the device.

[0049] By employing a cylinder 21 as the drive mechanism 2, and with its movable end 211 extending and retracting along the axial direction of the positioning cylinder 11, precise, rapid, and stable drive control of the movable rod 12 can be achieved. This design utilizes the linear extension and retraction characteristics of the cylinder 21 to ensure that the movable rod 12 moves smoothly along the axial direction during the positioning operation, avoiding positioning inaccuracies caused by motion deviations. Simultaneously, the use of the cylinder 21 makes the drive process simple and reliable, easily facilitating automated control, significantly improving the efficiency and accuracy of the positioning operation, reducing manual intervention, and thus enhancing the overall performance and production efficiency of the relay processing positioning device 100.

[0050] In one embodiment, the relay processing positioning device 100 further includes a base plate 3, which has a top surface and a bottom surface. A groove 31 is formed on the top surface, and a limiting hole 32 is provided at the bottom of the groove 31, connecting the groove 31 and the bottom surface. This design, through the groove 31 and the limiting hole 32 on the base plate 3, provides precise installation and movement guidance for the abutment member 22 and the positioning cylinder 11. The sliding arrangement within the groove 31 allows the abutment member 22 to move smoothly along a predetermined path, ensuring stable contact with the rolling element 15 of the movable rod 12; while the limiting hole 32 precisely fixes the position of the positioning cylinder 11, ensuring its coaxiality and movement accuracy with the movable rod 12. This structure not only improves the overall stability and reliability of the positioning device but also facilitates assembly and maintenance, reduces production costs, and ensures high-precision coaxial positioning of the iron frame and the cylindrical core 230 during relay processing, improving product quality and consistency.

[0051] This utility model also proposes a relay assembly device, which includes a relay processing and positioning device 100. The specific structure of the relay processing and positioning device 100 is as described in the above embodiments. Since this relay assembly device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0052] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
