A circuit breaker mounting positioning device

Abstract

This utility model relates to the field of positioning device technology and provides a circuit breaker installation and positioning device, including: a base, a support tray, a mounting plate, a contact plate, and a positioning mechanism. In this solution, by setting up a positioning mechanism, the rotation of the support tray allows the synchronous rod to slide within the limiting groove. The limiting groove, through its limiting effect, drives the docking groove to move up and down. The docking groove then drives the lever to move axially, thereby driving the active rod to slide axially. Simultaneously, the first and second linkage rods drive the linkage slider and the driven slider to slide synchronously. The symmetrically arranged driven slider and the centrally located active slider then position the circuit breaker in three directions and lock it against the contact plate, achieving rapid installation and positioning of the circuit breaker. Furthermore, the synchronous rod and limiting groove allow multiple positioning mechanisms to move synchronously during rotation, ensuring circuit breaker positioning accuracy while significantly improving production cycle time.

Description

Technical Field

[0001] This utility model belongs to the field of positioning device technology, and in particular relates to a circuit breaker installation positioning device. Background Technology

[0002] A circuit breaker is a switching device that can close, carry, and interrupt current under normal circuit conditions and close, carry, and interrupt current under abnormal circuit conditions within a specified time. It can automatically disconnect the circuit when a serious overload, short circuit, or undervoltage fault occurs. Moreover, it generally does not require replacement of components after interrupting the fault current, and has been widely used.

[0003] Currently, in order to ensure the quality of circuit breakers before they leave the factory, they need to be tested. In the circuit breaker production and testing process, the product to be tested needs to be fixed on the testing platform for electrical performance, mechanical characteristics and other tests. System testing is also required. Before testing, it needs to be installed and positioned in a designated location so that the testing equipment can perform the testing operation.

[0004] Although there are various types of installation and positioning devices available, some problems still exist. For example, before each batch of tests, the circuit breaker position needs to be manually calibrated using mechanical clamps. This stage requires technicians to repeatedly observe and fine-tune, determining the optimal positioning point through visual judgment and tactile feedback. This relies entirely on the operator's experience, leading to significant differences in the results of different operators. At the same time, this step is significantly affected by human factors. Furthermore, after a single unit is tested, the circuit breaker must be completely unloaded before the next unit can be tested, which takes a long time, affects the production testing cycle, and prevents the realization of assembly line-style testing operations, seriously impacting production efficiency. Utility Model Content

[0005] This utility model provides a circuit breaker installation positioning device, which aims to solve the problem that the current installation positioning device relies on manual positioning, which is prone to errors, and the "installation-inspection-disassembly-installation" steps seriously slow down the production and inspection cycle.

[0006] This utility model is implemented as follows: a circuit breaker installation and positioning device includes: a base, a support tray, a mounting plate, a contact plate, and a positioning mechanism. The support tray is coaxially rotatably connected to the top of the cylindrical base. The mounting plate is connected to the upper surface of the support tray. The contact plate is vertically fixed to one end of the mounting plate near the axis of the support tray. The positioning mechanism is disposed on the mounting plate.

[0007] The positioning mechanism includes a slide groove, an active slider, a linked slider, a driven slider, and a linkage unit. The slide groove is provided on the top of the mounting plate and there are multiple slide grooves. The active slider, the linked slider, and the driven slider are respectively slidably engaged in the slide groove. The linked slider is located between the active slider and the driven slider, and there is an included angle between the active slider and the driven slider.

[0008] The linkage unit includes a first linkage rod and a second linkage rod. One end of the first linkage rod and the second linkage rod are rotatably connected to each other and located on the linkage slider. The other end of the first linkage rod is rotatably connected to the driven slider, and the other end of the second linkage rod is rotatably connected to the driving slider.

[0009] Preferably, the positioning mechanism further includes a locking block and an active rod. The locking block is fixed to the end of the mounting plate away from the abutment plate, and the active rod is slidably connected to the locking block, with one end of the active rod connected to the active slider.

[0010] Preferably, the linkage unit further includes a slot, an adjusting plate, a docking groove, and a lever. The slot is disposed through the edge of the support tray. The adjusting plate is slidably connected in the slot. The docking groove is vertically recessed at the top center of the adjusting plate. The other end of the active rod is slidably engaged in the docking groove. The adjusting groove is disposed on the side wall of the adjusting plate and communicates with the docking groove. The lever is fixed on the active rod and slidably engaged in the adjusting groove.

[0011] Preferably, the linkage unit further includes a synchronizing rod and a limiting groove. One end of the synchronizing rod is fixed to the adjusting plate, and the other end is slidably engaged in the limiting groove. The limiting groove is recessed on the outer wall of the base. The limiting groove has an irregular shape and a height difference.

[0012] Preferably, one end of both the active slider and the driven slider is fixed with a docking rod, one end of the docking rod is slidably fitted with a positioning cylinder, and a return spring is fitted outside the docking rod, with one end of the return spring abutting against the positioning cylinder.

[0013] Preferably, multiple positioning mechanisms are provided on the pallet, and the multiple positioning mechanisms are arranged at equal angles.

[0014] Compared with the prior art, the embodiments of this application have the following main advantages:

[0015] In this solution, a positioning mechanism is set up, and the rotation of the support tray allows the synchronous rod to slide within the limiting groove. The limiting groove, in turn, drives the docking groove to move up and down. The docking groove then drives the lever to move axially, which in turn drives the active rod to slide axially. Simultaneously, the first and second linkage rods drive the linkage slider and the driven slider to slide synchronously. The symmetrically arranged driven slider and the active slider located at the center position the circuit breaker in three directions and lock it against the abutment plate, achieving a rapid installation and positioning effect for the circuit breaker. In conjunction with the synchronous rod and the limiting groove, multiple positioning mechanisms can be synchronously linked during rotation, realizing a streamlined clamping and positioning operation. While ensuring the positioning accuracy of the circuit breaker, it also significantly improves the production cycle time, making it simple, efficient, and practical. Attached Figure Description

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] This utility model embodiment provides a circuit breaker installation and positioning device, such as... Figure 1-4 As shown, it includes: a base 1, a support tray 2, a mounting plate 3, a contact plate 4, and a positioning mechanism 5. The support tray 2 is coaxially rotatably connected to the top of the cylindrical base 1. The mounting plate 3 is connected to the upper surface of the support tray 2. The contact plate 4 is vertically fixed on the mounting plate 3 at one end near the axis of the support tray 2. The positioning mechanism 5 is set on the mounting plate 3.

[0024] The positioning mechanism 5 includes a slide groove 51, an active slider 52, a linkage slider 53, a driven slider 54, and a linkage unit. The slide groove 51 is located on the top of the mounting plate 3 and has multiple slide grooves. The active slider 52, the linkage slider 53, and the driven slider 54 are respectively slidably engaged in the slide groove 51. The linkage slider 53 is located between the active slider 52 and the driven slider 54, and there is an included angle between the active slider 52 and the driven slider 54.

[0025] The linkage unit includes a first linkage rod 55 and a second linkage rod 56. One end of the first linkage rod 55 and the second linkage rod 56 are rotatably connected to each other and are located on the linkage slider 53. The other end of the first linkage rod 55 is rotatably connected to the driven slider 54, and the other end of the second linkage rod 56 is rotatably connected to the active slider 52.

[0026] The positioning mechanism 5 also includes a locking block 57 and an active rod 58. The locking block 57 is fixed on the mounting plate 3 at one end away from the abutment plate 4. The active rod 58 is slidably connected to the locking block 57, and one end of the active rod 58 is connected to the active slider 52.

[0027] The linkage unit also includes a slot 59, an adjusting plate 510, a docking groove 511, an adjusting groove 512, and a lever 513. The slot 59 is disposed through the edge of the support tray 2. The adjusting plate 510 is slidably connected in the slot 59. The docking groove 511 is recessed vertically at the top center of the adjusting plate 510. The other end of the active rod 58 is slidably engaged in the docking groove 511. The adjusting groove 512 is disposed on the side wall of the adjusting plate 510 and communicates with the docking groove 511. The lever 513 is fixed on the active rod 58 and slidably engaged in the adjusting groove 512.

[0028] The linkage unit also includes a synchronizing rod 514 and a limiting groove 515. One end of the synchronizing rod 514 is fixed on the adjusting plate 510, and the other end is slidably engaged in the limiting groove 515. The limiting groove 515 is recessed on the outer wall of the base 1. The limiting groove 515 has an irregular shape and a height difference.

[0029] It should be noted that, because existing circuit breakers require manual calibration of their position using mechanical clamps before testing, this stage necessitates repeated observation and fine-tuning by technicians. The optimal positioning point is determined through visual judgment and tactile feedback, relying entirely on operator experience. This leads to significant differences in results among different operators, and this process is significantly influenced by human factors. Furthermore, after each unit is tested, the circuit breaker must be completely unloaded before the next unit can be tested, resulting in a lengthy process that impacts production testing rhythm and prevents streamlined testing operations, severely affecting production efficiency. To address this issue, this solution incorporates a positioning mechanism 5. The rotation of the support tray 2 allows the synchronizing rod 514 to slide within the limiting groove 515, and through the limiting groove 51... The limiting action of 5 drives the docking groove 511 to move up and down. The docking groove 511 drives the lever 513 to move in conjunction, which in turn drives the active rod 58 to slide axially. At the same time, the first linkage rod 55 and the second linkage rod 56 drive the linkage slider 53 and the driven slider 54 to slide synchronously. The symmetrically arranged driven slider 54 and the active slider 52 located at the center position the circuit breaker in three directions and lock it against the abutment plate 4, achieving a rapid installation and positioning effect for the circuit breaker. In conjunction with the synchronizing rod 514 and the limiting groove 515, multiple positioning mechanisms 5 can move in conjunction synchronously when rotating, realizing a production line-style clamping and positioning operation. While ensuring the positioning accuracy of the circuit breaker, it also greatly improves the production cycle, which is simple, efficient and practical.

[0030] Specifically, in this embodiment, the solution mainly includes a base 1, a support tray 2, a mounting plate 3, a contact plate 4, and a positioning mechanism 5. In use, the circuit breaker to be tested is first placed on the mounting plate 3, and then the support tray 2 is rotated. At this time, one end of the synchronizing rod 514 slides in the limiting groove 515, and the limiting action of the limiting groove 515 drives the adjusting plate 510 to move up and down. During the movement, the lever 513 is linked in the adjusting groove 512 and drives the active rod 58 to move axially. The active rod 58 drives the active slider 52 to move, and at the same time, the first linkage rod 55 and the second linkage rod 56 synchronously drive the linkage slider 53 and the driven slider 54 to slide synchronously. Then, the circuit breaker is positioned in three directions by the symmetrically arranged driven slider 54 and the active slider 52 located at the center, and then locked against the contact plate 4.

[0031] In a further preferred embodiment of this utility model, such as Figure 1-4As shown, a docking rod 6 is fixed to one end of both the active slider 52 and the driven slider 54. A positioning cylinder 7 is slidably sleeved on one end of the docking rod 6, and a return spring 8 is sleeved on the outside of the docking rod 6. One end of the return spring 8 abuts against the positioning cylinder 7.

[0032] In this embodiment, the positioning cylinder 7 can slide to a certain extent when it comes into contact with the circuit breaker by the setting of the docking rod 6, and the circuit breaker is locked by the elastic force of the return spring 8.

[0033] In a further preferred embodiment of this utility model, such as Figure 1-4 As shown, multiple positioning mechanisms 5 are provided on the pallet 2, and the multiple positioning mechanisms 5 are arranged at equal angles.

[0034] In this embodiment, multiple positioning mechanisms 5 enable the device to perform loading and unloading operations on multiple circuit breakers at one time by rotating the support tray 2, thereby improving work efficiency.
