Combined fixture for circuit breaker housing processing

Abstract

The invention relates to a combined fixture for machining of a breaker shell. The combined fixture comprises a base and supports. The supports can move on the base. The supports are structurally characterized in that each support comprises a horizontal plate connected with the base and a vertical plate used for positioning a workpiece, vertical inner sides of each opposing two of the vertical plates are provided with slants used for supporting a workpiece flange, the upper horizontal plane of each vertical plate is provided with a fixing hole, a slider positioner is arranged on the transverse outer side of the upper portion of each vertical plate, each slider positioner is arranged obliquely and upwardly from outside to inside in the vertical direction, each slider positioner comprises a slider holder and a slider, the center of each slider holder is provided with a threaded through hole in the vertical direction, each slider is disposed at the front end of the corresponding slider holder, guide bolts are arranged in the threaded through holes, the top end of each slider is provided with threaded blind holes, the bottom end of each slider is in contact with the corresponding flange, each vertical plate is provided with a corner cylinder, and the executive end of each corner cylinder is abutted to the corresponding flange end. The combined fixture has the advantages that machining quality and production efficiency are both effectively improved.

Description

[0001] Technical field [0002] The invention relates to a machine tool fixture, in particular to an adjustable combined machine tool fixture used for mechanical processing of circuit breaker shells, which are key components of high-voltage switchgear at various levels in smart grids. Background technique [0003] Circuit breaker housing is a key accessory for high-voltage switchgear. It is widely used in high-voltage, ultra-high voltage, ultra-high voltage and other voltage level switchgears. Its performance plays a vital role in the overall performance and technical level of high-voltage switchgear. With the construction and development of smart grid, high-voltage switchgear adopts a large number of new technologies, various functions are more complex, performance stability requirements are higher, and the overall processing quality level of the circuit breaker shell is also getting higher and higher, and in order to seize The market competition takes the lead and strengthen...

Problems solved by technology

When the product is changed for processing, the fixture needs to be replaced at the same time. After the fixture is replaced, the relative positions of the fixture and the table, the tool and the workpiece need to be adjusted for a long time, thereby reducing the production efficiency of the product.

However, the positioning element is manually operated, the positioning adjustment is cumbersome, the production efficiency is low, and the positioning accuracy is poor, and the product processing position accuracy is low.

The workpiece is clamped with a belt clamping device, the workpiece bounces a lot during processing, and the processing accuracy is low
