Description

Technical Field

[0001] This invention relates to the field of junction box manufacturing equipment technology, specifically a positioning and enlarging device for manufacturing junction boxes for electrical equipment. Background Technology

[0002] Electrical equipment is a general term for equipment such as generators, transformers, power lines, and circuit breakers in a power system. Electricity plays an indispensable role in our lives and production, bringing us great convenience and becoming a vital energy source. The most critical factor in power plants ensuring the normal operation and transmission of electricity is the electrical equipment.

[0003] In the existing technology, electrical equipment junction boxes are usually made by casting. After the machining is completed, because the hole diameter on the junction box is small, it is necessary to re-enlarge the hole to avoid blockage. The commonly used manual hole enlargement method is inefficient and has low precision, which can easily lead to inconsistent junction box quality. Summary of the Invention

[0004] To address the problems mentioned in the background art, the present invention provides a positioning and enlarging device for manufacturing junction boxes for electrical equipment.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A positioning and enlarging device for manufacturing junction boxes for electrical equipment includes a first conveyor belt and a second conveyor belt, with a gap between the first conveyor belt and the second conveyor belt, and limit plates provided on the front and rear sides of the first conveyor belt and the second conveyor belt.

[0007] An installation block is provided above the gap, and the installation block is bolted to the bottom end of the lifting mechanism. A positioning component is provided on the left side of the lower end face of the installation block, and a balancing clamping component is provided on the right side of the lower end face of the installation block. The positioning component and the balancing clamping component are detachably installed on the lower end face of the installation block by bolts. The positioning component includes a connecting rod, a positioning wheel is rotatably installed at the bottom of the connecting rod, the top of the connecting rod is connected to the bottom end of the sliding rod, the top of the sliding rod is slidably installed in a sleeve, a spring is sleeved on the outside of the sliding rod, and the top of the sleeve is bolted to the lower end face of the installation block. The balancing clamping component includes a connecting rod, a positioning wheel, a spring, and a sleeve.

[0008] A drill bit is detachably mounted on the lower end face of the mounting block, and the drill bit is connected to the motor drive.

[0009] Furthermore, the motor is fixed in the mounting slot, which is formed on the lower end face of the mounting block.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] The finished electrical equipment junction boxes are sequentially placed on the limiting plate and conveyed. When they pass through the gap between the limiting plate and the first conveyor belt, the positioning wheel of the upper positioning component remains in contact with the upper surface of the junction box. When the positioning wheel rolls to the hole on the junction box, it gets stuck in the hole. At this time, the pressure of the positioning wheel changes, which is fed back to the central processing unit, achieving the technical effect of positioning. The central processing unit then controls the first and second conveyor belts to stop, and the lifting mechanism and motor to start, descending to perform positioning and hole enlargement operations at the set position. During the descent, the connecting rod and the positioning wheel simultaneously press and fix the two sides of the junction box, ensuring the stability of the junction box during the hole enlargement process. The structure and principle of this invention are simple. Positioning and hole enlargement are achieved through the pressure change when the positioning wheel gets stuck in the hole. At the same time, the positioning component and the drill bit are both designed to be replaceable, ensuring applicability to different junction boxes. Attached Figure Description

[0024] The working principle of this invention is as follows: The finished electrical equipment junction boxes are sequentially placed on the limiting plate 1 for conveying. When they pass through the gap 4 between the limiting plate 1 and the first conveyor belt 2, the positioning wheel 52 of the upper positioning component 5 remains in contact with the upper surface of the junction box. When the positioning wheel 52 rolls to the hole on the junction box, it gets stuck in the hole. At this time, the pressure of the positioning wheel 52 changes, which is fed back to the central processing unit, achieving the technical effect of positioning. The central processing unit then controls the first conveyor belt 2 and the second conveyor belt 3 to stop, and the lifting mechanism 8 and the motor 10 to start, descending to perform a positioning and hole-expanding operation at the set position. During the descent, the connecting rod 51 and the positioning wheel 52 simultaneously press and fix both sides of the junction box, ensuring the stability of the junction box during the hole-expanding process. This invention has a simple structural principle, using the pressure change when the positioning wheel gets stuck in the hole to achieve positioning and hole expansion. Furthermore, both the positioning component 5 and the drill bit 9 are replaceable, ensuring applicability to different junction boxes.
