Description

Mechanism swing arm crimping fixture

technical field

The utility model relates to a fixture, in particular to a mechanism swing arm crimping fixture.

Background technique

With the development of the power industry, more and more circuit breaker cabinets are used, and there is a large demand for circuit breaker spring mechanisms relative to the industry. For the manufacturer, based on the structural design of the spring operating mechanism of the circuit breaker, an interference fit is required when the swing arm and the mechanism are assembled. As far as the current situation is concerned, many companies use a hammer to manually knock the swing arm onto the mechanism, which not only reduces the processing efficiency, but also easily damages the workpiece, and at the same time, the staff is easily injured. For the large demand in the circuit breaker spring operation mechanism market, we need an efficient and accurate automation equipment to improve the crimping fixture.

The technical scheme adopted by the utility model is: the utility model includes a mounting plate, a clamp arranged on the mounting plate and a crimping mechanism arranged above the clamp, and the clamp includes a clamp arranged on the mounting plate Bottom plate, several support rods, several limit plates and bottom support heads, several support rods are vertically arranged on the bottom plate, several limit plates are arranged on the bottom plate and located in several The outer side of the enclosing circle of the support rods, the bottom support head is arranged on the bottom plate and located in the enclosing circles of several of the support rods.

Further, an upper pressure head is provided above the bottom support head, a first relief groove is provided at the bottom of the upper pressure head, and a second relief groove is provided at the side of the upper pressure head.

Further, the upper end of the bottom support head is provided with a convex ring.

Further, the bottom of the support rod is provided with a pad column.

Further, the crimping mechanism includes a base plate located above the clamp, a drive unit arranged on the base plate, and a crimping rod connected to the drive unit in transmission, the tail of the crimping rod is connected to the drive unit transmission connection, the head of the crimping rod passes through the base plate and is provided with a pressing plate, the crimping mechanism also includes a controller connected to the drive unit, and a There are several support columns.

Further, several guide rods are fixedly arranged on the pressing plate, and the guide rods are slidably connected with the base plate.

Further, the drive unit is a motor, or an air cylinder, or a hydraulic cylinder.

The beneficial effects of the utility model are: because the utility model adopts the design of the crimping jig, the utility model includes a mounting plate, a clamp arranged on the mounting plate and a crimping mechanism arranged above the clamp, so The fixture includes a base plate arranged on the mounting plate, several support rods, several limit plates and bottom support heads, several support rods are vertically arranged on the base plate, and several limit plates The bottom support head is arranged on the bottom plate and located outside the enclosing circles of several support rods, and the bottom support head is arranged on the base plate and located in the enclosing circles of several support rods. It can be seen that compared with the existing assembly technology, the utility model adopts a mechatronics control system to complete the positioning of the swing arm to the mechanism, automatically compress the swing arm, and protect the appearance of the parts. Compared with the traditional hand-assembled swing arm, the hydraulic crimping fixture greatly reduces the consumption of manpower and material resources, and brings considerable economic benefits to the enterprise. Moreover, the quality and appearance of the product are guaranteed, and the appearance damage and quality defects caused by human operation are avoided. In addition, compared with manual operation, hydraulic crimping fixtures are much less labor-intensive, which can reduce the labor intensity of employees and greatly improve production efficiency.
