Therefore, the application greatly improves the assembling efficiency of the spring pin and is convenient to operate.

Description

Technical Field

[0001] This invention relates to an assembly device, and more particularly to a spring pin assembly device. Background Technology

[0002] A current type of fuse includes a fuse tube, a fusible element, and two conductive plates. The fusible element is located within the fuse tube, and the two conductive plates seal both ends of the fusible element and are electrically connected to it. Each conductive plate is specifically fixed to the fuse tube by three spring-loaded pins. Therefore, when assembling the fuse, spring-loaded pins need to be pressed into three mounting holes at both ends of the fuse tube. The traditional approach is to simply position the fuse and then manually tap the spring-loaded pins into the corresponding mounting holes. This method suffers from low assembly efficiency and cumbersome operation. Summary of the Invention

[0003] The purpose of this invention is to address the technical problems existing in the prior art by providing a spring pin assembly device that is highly efficient and easy to operate.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a spring pin assembly device, including a support carrier, a positioning seat, and a pressing mechanism. The positioning seat is disposed on the support carrier and has a pressing channel and a circular positioning groove for inserting the end of the fuse and allowing the fuse to rotate to change the assembly position. The pressing channel communicates with the positioning groove and is arranged radially along the positioning groove. The pressing mechanism includes a driving component, a pressing rod, and a transmission assembly. The driving component is disposed on the support carrier and is connected to the pressing rod through the transmission assembly to drive the pressing rod to press the spring pin located in the pressing channel into the corresponding spring pin mounting hole of the fuse.

[0005] Furthermore, the transmission assembly includes a transmission rod and a slider. The slider is slidably disposed on the support carrier along the pressing direction. The pressing rod is disposed on the slider, and the pressing rod partially extends into the pressing channel. One end of the transmission rod is hinged to the slider, and the other end of the transmission rod is hinged to the driving member. The driving member is an operating rod, which is mounted on the support carrier in the form of a lever, and the rotation axis of the operating rod is parallel to the axis of the positioning groove.

[0006] Furthermore, the pressing mechanism also includes a reset assembly for resetting the slider and the operating rod. The reset assembly includes a first tension spring and a second tension spring. The two ends of the first tension spring are respectively connected to the slider and a first fixing member provided on the support carrier, and the two ends of the second tension spring are respectively connected to the operating rod and a second fixing member provided on the support carrier.

[0007] Furthermore, the first fixing member and the second fixing member can be moved along the sliding direction of the slider to adjust their positions.

[0008] Furthermore, the pressing mechanism also includes a limiting component for limiting the rotation angle of the operating lever. The limiting component includes two limiting rods, which are respectively disposed on the support carrier and cooperate with the opposite sides of the operating lever. The two limiting rods are adjustable to adjust the rotation angle of the operating lever.

[0009] Furthermore, a spring ball is provided on the side wall of the positioning groove, which can be engaged or disengaged from the corresponding spring pin mounting hole of the fuse.

[0010] Furthermore, the side wall of the positioning groove is provided with an arc-shaped observation groove, through which the crimping channel passes.

[0011] Furthermore, the axis of the positioning groove is located in the vertical direction, and the positioning groove includes an upper groove for accommodating the fuse tube end and a lower groove for accommodating the conductive plate extension of the fuse. The radial dimension of the upper groove is larger than that of the lower groove; the crimping channel penetrates through the upper groove.

[0012] Furthermore, the inner wall of the crimping channel is provided with an opening for the spring pin to enter and exit.

[0013] Furthermore, the supporting carrier is a fixed plate, which is set on a workbench.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The positioning seat and pressing mechanism allow the present invention to complete the assembly of one spring pin simply by positioning the fuse through the positioning groove and then driving the pressing rod through the driving component. Furthermore, the assembly position can be changed by rotating the fuse, thus allowing the assembly of three spring pins on the same end of the fuse to be completed sequentially without changing the orientation of the pressing mechanism. Therefore, the present invention greatly improves the assembly efficiency of spring pins and is easy to operate.

[0016] 2. The transmission assembly preferably includes the transmission rod and the slider, and the driving component is preferably an operating rod, so that the present invention also has the characteristics of simple structure, energy saving and no working noise.

[0017] 3. The arc-shaped observation groove not only facilitates the observation of the spring pin's crimping condition, but also serves as a clearance mechanism, making it easier to remove the fuse in the event that the spring pin fails to crimp (i.e., the spring pin is not fully crimped in).

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments; however, the spring pin assembly device of the present invention is not limited to the embodiments. Attached Figure Description

[0026] For an example, please refer to [link / reference]. Figures 1-7 As shown, a spring pin assembly device of the present invention includes a support carrier, a positioning seat 1, and a pressing mechanism 2. The positioning seat 1 is disposed on the support carrier and has a pressing channel 12 and a circular positioning groove 11 for inserting the end of the fuse and allowing the fuse to rotate to change the assembly position. The pressing channel 12 communicates with the positioning groove 11 and is arranged radially along the positioning groove 11. The pressing mechanism 2 includes a driving member, a pressing rod 24, and a transmission assembly. The driving member is disposed on the support carrier and is connected to the pressing rod 24 through the transmission assembly to drive the pressing rod 24 to press the spring pin located in the pressing channel 12 into the corresponding spring pin mounting hole of the fuse.

[0027] In this embodiment, the transmission assembly includes a transmission rod 22 and a slider 23. The slider 23 is slidably disposed on the support carrier along the pressing direction. The pressing rod 24 is disposed on the slider 23, and the pressing rod 24 partially extends into the pressing channel 12. One end of the transmission rod 22 is hinged to the slider 23, and the other end of the transmission rod 22 is hinged to the driving member, which is an operating rod 21. The operating rod 21 is mounted on the support carrier in the form of a lever, and the rotation axis of the operating rod 21 is parallel to the axis of the positioning groove 11. The power arm of the operating rod 21 is greater than the resistance arm. The rotation axes at both ends of the transmission rod 22 are parallel to the rotation axis of the operating rod 21. The operating rod 21 is specifically rotatably connected between the upper and lower ends of a U-shaped frame 51 in a horizontal position disposed on the support carrier. The slider 23 is specifically mounted on the support carrier via a sliding guide mechanism. This sliding guide mechanism includes an I-shaped groove 232 at the bottom of the slider 23 and an I-shaped rail 55 on the support carrier, with the groove 232 and the rail 55 slidably engaged. A T-shaped groove 233 is provided on the side of the slider 23 near the positioning seat 1. One end of the pressing rod 24 extends into the pressing channel 12, and the other end can be detachably inserted into the T-shaped groove 233.

[0028] In this embodiment, the pressing mechanism 2 further includes a reset assembly for resetting the slider 23 and the operating rod 21. The reset assembly specifically includes a first tension spring 25 and a second tension spring 26. The first tension spring 25 is connected at both ends to the slider 23 and a first fixing member 27 on the support carrier, respectively. The second tension spring 26 is connected at both ends to the operating rod 21 and a second fixing member 28 on the support carrier, respectively. Specifically, the first tension spring 25 is hung at both ends on a first hanging rod 231 and a first fixing member 27 on the side of the slider 23, respectively. The second tension spring 26 is hung at both ends on a second hanging rod 211 and a second fixing member 28 at the bottom of one end of the operating rod 21, respectively. The second hanging rod 211 is located near the hinge point between the operating rod 21 and the transmission rod 22.

[0029] In this embodiment, the first fixing member 27 and the second fixing member 28 can be moved along the sliding direction of the slider 23 to adjust their positions. Specifically, the support carrier has at least one row of first fixing holes 52 arranged along the sliding direction of the slider 23 at the position of the first fixing member 27. By selecting different first fixing holes to connect and cooperate with the first fixing member 27, the position of the first fixing member 27 can be adjusted, thereby adjusting the tension of the first tension spring 25. The support carrier has at least one row of second fixing holes 52 arranged along the sliding direction of the slider 23 at the position of the second fixing member 28. By selecting different second fixing holes to connect and cooperate with the second fixing member 28, the position of the second fixing member 28 can be adjusted, thereby adjusting the tension of the second tension spring 26.

[0030] In this embodiment, the pressing mechanism 2 further includes a limiting component for limiting the rotation angle of the operating rod 21. This limiting component includes two limiting rods 29, which are respectively disposed on the support carrier and cooperate with opposite sides of the operating rod 21. The two limiting rods 29 are adjustable to adjust the rotation angle of the operating rod 21. Specifically, each limiting rod 29 is screwed onto a fixing block 54 disposed on the support carrier, and the two limiting rods 29 are horizontal and arranged opposite each other.

[0031] In this embodiment, a spring ball 7 is provided on the side wall of the positioning groove 11. The spring ball 7 can be engaged or disengaged from the corresponding spring pin mounting hole of the fuse. The spring ball 7 has an external thread, which is threaded onto the positioning seat 1. The end of the spring ball 7 away from the center of the positioning groove 11 is visible and can be rotated to adjust the degree of engagement between the spring ball 7 and the corresponding spring pin mounting hole of the fuse.

[0032] In this embodiment, as Figure 7 As shown, the positioning groove 11 has an arc-shaped observation groove 13 on its side wall, and the crimping channel 12 passes through the observation groove 13. The arc-shaped observation groove 13 not only facilitates observation of the crimping status of the spring pin but also provides clearance, allowing for easy removal of the fuse in case the spring pin fails to crimp (i.e., the spring pin is not fully pressed in). The axis of the positioning groove 11 is located in the vertical direction. The positioning groove 11 includes an upper groove 111 for accommodating the fuse tube end of the fuse and a lower groove 112 for accommodating the conductive plate extension of the fuse. The radial dimension of the upper groove 111 is larger than the radial dimension of the lower groove 112. The crimping channel 12 passes through the upper groove 111, and the observation groove 13 is located on the side wall of the upper groove 111. The inner wall of the crimping channel 12 has an opening 121 to facilitate the entry and exit of the spring pin.

[0033] In this embodiment, the supporting carrier is a fixed plate 5, which is mounted on a workbench 6.

[0034] In the spring pin assembly device of the present invention, during installation, one end of the fuse 3 of the spring pin to be assembled is first inserted into the positioning groove 11 (e.g., Figure 6 As shown), ensure that one of the spring pin mounting holes on this end of the fuse 3 is aligned with the crimping channel 12. At this time, the spring ball 7 engages with one of the other two spring pin mounting holes on this end of the fuse, effectively positioning the fuse 3. Next, insert one spring pin 4 into the crimping channel 12 (as shown). Figure 6As shown, rotate the operating lever 21, causing it to push the slider 23 towards the positioning seat 1 via the transmission lever 22. This drives the crimping lever 24 to move along the crimping channel 12, pressing the spring pin 4 located in the crimping channel 12 into the corresponding spring pin mounting hole of the fuse 3. After assembling the first spring pin, release the operating lever 21. The first tension spring 25 and the second tension spring 26 respectively drive the slider 23 and the operating lever 21 to reset. Then, rotate the fuse 120° to place the second spring pin into the crimping channel 12, and repeat the above operation to complete the assembly of the second spring pin. Repeat this operation until the assembly of the third spring pin on the same end of the fuse is completed. Afterward, pull out the fuse, insert the other end of the fuse into the positioning groove 11, and repeat the above steps to complete the assembly of the three spring pins on the other end of the fuse.

[0035] This invention assembles a single spring pin by simply positioning the fuse using a positioning slot and then moving the crimping rod via an operating lever. Furthermore, the assembly position can be changed by rotating the fuse, allowing for the sequential assembly of three spring pins on the same end of the fuse without altering the orientation of the crimping mechanism. Therefore, this invention significantly improves the assembly efficiency of spring pins, and is also convenient to operate, simple in structure, energy-efficient, and operates without noise.

[0036] The above embodiments are only used to further illustrate a spring pin assembly device of the present invention, but the present invention is not limited to the embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the technical solution of the present invention.
