Description

Technical Field

[0001] This utility model relates to the field of vacuum interrupter assembly technology, and in particular to a tooling fixture for assembling vacuum interrupters in circuit breaker cabinets. Background Technology

[0002] The moving end of the vacuum interrupter is connected to the insulating tie rod via a flexible connection. The assembly of the flexible connection is mostly done manually. The worker places the vacuum interrupter on the foam cotton carrier plate, assembles the flexible connection and tie rod, and tightens it manually with a wrench. The assembly of the spring, spring seat and shaft pin is done by first securing it with a screwdriver, then pressing the spring seat down to allow the spring to pass through the shaft pin. Manual installation is inefficient, has poor accuracy, and is greatly affected by the worker's skill level, making it easy to make mistakes that could damage the interrupter. Therefore, this utility model proposes a tooling fixture for assembling the vacuum interrupter of a circuit breaker cabinet. Utility Model Content

[0003] The main purpose of this utility model is to provide a tooling fixture for assembling the vacuum interrupter chamber of a circuit breaker cabinet. The quick clamp drives the push rod and the push block to press the spring, which is more labor-saving, safer, more efficient, and produces more stable and reliable product quality compared to manually pressing the spring. The front limit plate and the rear limit plate are fixed to the U-shaped plate with screws, and multiple sets are provided to facilitate disassembly and replacement, so as to adapt to different specifications of interrupters chambers.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: a fixture for assembling a vacuum interrupter chamber of a circuit breaker cabinet, comprising a workbench, an mounting clamp disposed on the workbench, and a pushing mechanism disposed on one side of the mounting clamp. The mounting clamp includes an upward-opening U-shaped plate disposed on the workbench surface. The inner sides of the two vertical portions of the U-shaped plate are respectively provided with a front limiting plate and a rear limiting plate. The top of the front limiting plate and the rear limiting plate are provided with limiting grooves. The left side of the front limiting plate is provided with an upper limiting plate. The bottom of the upper limiting plate is provided with an clearance groove. The right side of the upper limiting plate is provided with a pressure block.

[0005] Preferably, the pushing mechanism includes a connecting block collinear with the U-shaped plate, and a push rod is slidably provided horizontally on the upper end surface of the connecting block through a guide sleeve. One end of the push rod is connected to a push block, and the other end of the push rod is driven by a quick clamp. The end of the push block is provided with a shaft pin clearance groove.

[0006] Preferably, one end of the upper limit plate is rotatably connected to the front limit plate via a pin, and the other end of the upper limit plate is fixed to the front limit plate via a pin.

[0007] Preferably, both the front limiting plate and the rear limiting plate are fixed to the inner side of the U-shaped plate by screws.

[0008] Preferably, the workbench is provided with a base plate, the U-shaped plate and the connecting block are both fixed on the base plate, and the base plate is fixed on the workbench surface by a table clamp.

[0009] The beneficial effects of this utility model's technical solution are:

[0010] The push rod and the push block are driven by the quick clamp to push the spring, which is more labor-saving, safer, more efficient and more stable than manually pressing the spring. The product quality is also more stable and reliable.

[0011] Both the front and rear limiting plates are fixed to the U-shaped plate with screws, and multiple sets are provided to facilitate disassembly and replacement, adapting to different specifications of arc-extinguishing chambers. Attached Figure Description

[0016] The present invention will be further described in detail below with reference to specific embodiments.

[0017] Example:

[0018] like Figure 1 and Figure 2 As shown, this utility model discloses a fixture for assembling a vacuum interrupter chamber of a circuit breaker cabinet, comprising a workbench 1, an mounting clamp disposed on the workbench 1, and a pushing mechanism disposed on one side of the mounting clamp. The mounting clamp includes an upward-opening U-shaped plate 2 disposed on the surface of the workbench 1. The inner sides of the two vertical portions of the U-shaped plate 2 are respectively provided with a front limiting plate 3 and a rear limiting plate 4. The top of the front limiting plate 3 and the rear limiting plate 4 are provided with limiting grooves 5. The left side of the front limiting plate 3 is provided with an upper limiting plate 6. The bottom of the upper limiting plate 6 is provided with a clearance groove. The right side of the upper limiting plate 6 is provided with a pressure block 7.

[0019] The pushing mechanism includes a connecting block 8 that is collinear with the U-shaped plate 2. The upper end surface of the connecting block 8 is provided with a push rod 9 that can slide horizontally through a guide sleeve. One end of the push rod 9 is connected to a push block 10, and the other end of the push rod 9 is driven by a quick clamp 20. The end of the push block 10 is provided with a shaft pin clearance groove 11.

[0020] One end of the upper limit plate 6 is rotatably connected to the front limit plate 3 via a pin, and the other end of the upper limit plate 6 is fixed to the front limit plate 3 via a pin 12.

[0021] Both the front limiting plate 3 and the rear limiting plate 4 are fixed to the inner side of the U-shaped plate 2 by screws, which facilitates the installation and replacement of the front limiting plate 3 and the rear limiting plate 4. Multiple sets of the front limiting plate 3 and the rear limiting plate 4 are provided to adapt to vacuum interrupters of different specifications.

[0022] The workbench 1 is provided with a base plate 13. The U-shaped plate 2 and the connecting block 8 are both fixed on the base plate 13. The base plate 13 is fixed on the workbench 1 surface by a table clamp 14, which facilitates the handling and carrying of the tooling fixture.

[0023] The working process of this utility model is as follows: The flexible connection 15 is pre-tightened and placed on the U-shaped plate 2 in conjunction with the pull rod 16 of the vacuum interrupter. The front limiting plate 3 and the rear limiting plate 4 limit the vacuum interrupter. The front limiting plate 3 and the upper limiting plate 6 cooperate to fix the vacuum interrupter. The torque is calibrated with a torque wrench, which saves time and effort. The spring 17 and the spring seat 18 are assembled on the vacuum interrupter. The push rod 9 is driven by the quick clamp 20 to drive the push block 10 to slide to the left. The push block 10 pushes the spring seat 18. Then, the shaft pin 19 is inserted into the middle of the pin relief groove of the push block 10. The quick clamp 20 is released. The spring seat 18 is blocked by the shaft pin 19, and the assembly is completed. The quick clamp 20 drives the push rod 9 and the push block 10 to push the spring 17, which is more labor-saving, safer, more efficient, and results in more stable and reliable product quality compared to manually pressing the spring 17.

[0024] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
