Description

Technical Field

[0001] This utility model relates to the field of circuit breaker manufacturing technology, and in particular to a clamping tool for drilling holes in a circuit breaker frame. Background Technology

[0002] Circuit breaker frames play a crucial role in modern power systems, primarily in the following aspects: 1) Protecting circuit safety: When overloads, short circuits, or other faults occur in the circuit, the circuit breaker frame can quickly and reliably interrupt the circuit, avoiding or reducing accidents and protecting electrical equipment and personnel safety. This is its most basic and critical function. 2) Controlling current: The circuit breaker frame can control the magnitude and direction of current, playing a role in regulating and controlling current. 3) Isolating circuits: During maintenance, repair, or safety maintenance of electrical equipment, the circuit breaker frame can isolate electrical equipment, cutting off the circuit between them to protect the safety of personnel. 4) Stabilizing power system operation: The circuit breaker frame can quickly detect abnormal currents or voltages in the circuit and automatically disconnect the circuit, preventing overcurrent, overvoltage, and other problems from affecting the normal operation of the power system, ensuring the stability and safety of the power system. 5) Coordinating the power system: The circuit breaker frame can also coordinate various parts of the power system, preventing overloading or other faults, thereby improving the efficiency and reliability of the power system. 6) Circuit status detection: The frame circuit breaker has a fault detection function, which can automatically detect the circuit status and promptly alarm when the circuit is abnormal. It can also record historical fault information of the circuit.

[0003] Circuit breaker frames often require the installation of embedded nuts, which is a cumbersome process. To address this, our company has improved the solution by using direct thread drilling instead of embedded nuts, which greatly reduces labor time and costs.

[0004] Existing clamping fixtures for drilling holes in circuit breaker frames have several shortcomings. First, they cannot reliably clamp the grating plate, making it prone to deformation and damage during thread drilling. Second, they cannot achieve continuous interval drilling, resulting in low drilling efficiency. Therefore, it is necessary to optimize and improve the existing clamping fixtures for drilling holes in circuit breaker frames. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned problems existing in the traditional technology and provide a clamping tool for drilling holes in a circuit breaker frame.

[0006] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:

[0007] A clamping fixture for drilling holes in a circuit breaker frame includes a worktable, a positioning component, a three-axis robot, and a clamping component. The positioning component is installed below the worktable, and the clamping component, whose position is adjusted by the three-axis robot, is installed around the periphery of the worktable.

[0008] The positioning component consists of a base plate, a lifting push rod, a push plate, and positioning blocks. The lifting push rod is installed on the upper side of the base plate, and several positioning blocks are installed on the movable end of the lifting push rod via the push plate.

[0009] The workbench has through holes to facilitate the extension of each positioning block;

The lead screw has two lead screw segments with opposite directions of rotation. A movable plate is sleeved on the outside of each lead screw segment. A clamping block is installed at the lower part of the movable plate. A boss is provided at the center of the inner side of the web of the channel plate. An avoidance channel for easy drilling is opened in both the web of the channel plate and the boss.

[0011] Furthermore, in the above-mentioned clamping fixture for drilling holes in the circuit breaker frame, the circuit breaker frame to be drilled includes a frame body, the frame body is provided with at least two rows of grid areas, each grid area has a cross-shaped through hole on its bottom side, a grid plate is provided between two adjacent grid areas, and the grid plate is provided with a protruding post as the drilling part.

[0012] Furthermore, in the aforementioned clamping fixture for drilling holes in the circuit breaker frame, the shape of the positioning block matches the shape of the cross-shaped through hole.

[0013] Furthermore, in the aforementioned clamping fixture for drilling holes in the circuit breaker frame, the position of the positioning block corresponds one-to-one with the position of the cross-shaped through hole.

[0014] Furthermore, in the aforementioned clamping fixture for drilling holes in the circuit breaker frame, the inner side of the clamping block is provided with an avoidance groove that matches the outer diameter of the protrusion.

[0015] Furthermore, in the aforementioned clamping fixture for drilling holes in the circuit breaker frame, the position of the clearance channel is offset from the position of the lead screw.

[0016] The beneficial effects of this utility model are:

[0017] This utility model has a reasonable structural design, mainly consisting of a worktable, a positioning component, a three-axis robot, and a clamping component.

[0032] In this embodiment, the circuit breaker frame 5 to be drilled includes a frame body 501, which has at least two rows of grid areas 502. Each grid area 502 has a cross-shaped through hole 503 on its bottom side. A grid plate 504 is provided between two adjacent grid areas 502, and a protrusion 505 is provided on the grid plate 504 as a drilling part.

[0033] In this embodiment, the positioning component 2 is composed of a base plate 201, a lifting push rod 202, a push plate 203, and positioning blocks 204. The lifting push rod 202 is installed on the upper side of the base plate 201. Several positioning blocks 204 are installed on the movable end of the lifting push rod 202 via the push plate 203. The shape of the positioning blocks 204 matches the shape of the cross-shaped through hole 503, and the position of the positioning blocks 204 corresponds one-to-one with the position of the cross-shaped through hole 503.

[0034] In this embodiment, the workbench 1 is provided with through holes to facilitate the extension of each positioning block 204.

[0035] In this embodiment, the clamping assembly 4 consists of a channel plate 401, a lead screw motor 402, a lead screw 403, a movable plate 404, a clamping block 405, and a boss 406. The lead screw motor 402 is fixed to the outer side of the channel plate 401. The lead screw 403 is installed at the output end of the lead screw motor 402. The lead screw 403 has two sections with opposite rotation directions, and a movable plate 404 is sleeved on the outer side of each section.
