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

Embodiment Construction

[0053] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0054] like figure 2 As shown, the fixture of the present invention includes a clamp body composed of a bottom plate 100 and 4 supports 200, a positioning element composed of 4 sets of slider positioning devices 300 and 4 sets of corner cylinder positioning devices 400, and a set of 2 sets of chain locking devices 500. The locking device and several connecting elements 600 are formed. Before installing the workpiece 000, according to the total length and diameter of the workpiece 000, adjust the installation positions of the four supports 200 on the base plate 100, and make them symmetrical with respect to the longitudinal and transverse centerlines of the base plate 100. After the positions are adjusted, place the Four supports 200 are fixed on the bottom plate 100 . The workpiece is placed, the flanges at both ends of the workpiece 000 are respecti...

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 strength...
