Abstract

The invention relates to a positioning and clamping device for high-precision space vertical hole system turning, and belongs to the field of turning positioning design. The positioning and clamping device comprises a large copper bush positioning and clamping device, a small copper bush positioning and clamping device and a cross lug, wherein the cross lug comprises a steel substrate, a large copper sleeve and a small copper sleeve, the steel substrate comprises a plate-shaped structure and a cylindrical structure, the plate-shaped structure is arranged on the outer wall of the cylindrical structure in the radial direction of the cylindrical structure, the plate-shaped structure and the cylindrical structure are integrally formed, the large copper bush and the small copper bush are both of a hollow cylindrical structure, the large copper bush is coaxially pressed in the cylindrical structure in the axial direction, the small copper bush is pressed on the plate-shaped structure, the large copper bush positioning and clamping device is used for vertically clamping the steel substrate and turning the large copper bush, and the small copper bush positioning and clamping device is usedfor horizontally clamping the steel substrate and turning the small copper bush. According to the positioning and clamping device, automatic centering and orienteering during workpiece clamping are achieved, and high-quality, high-efficiency and low-labor-intensity turning of a high-precision space vertical hole system of the cross lug is achieved.

Description

technical field [0001] The invention belongs to the field of turning positioning design, and relates to a positioning and clamping device for high-precision space vertical hole system turning processing. Background technique [0002] Among the electromechanical series products designed and produced at present, the structural characteristics and accuracy requirements of the cross lug components of each electromechanical actuator are basically the same. The characteristics are: the shape and position accuracy of the space vertical hole system is high. [0003] However, in the existing technology, there are generally recognized technical difficulties in the processing of the cross lug assembly of the electromechanical actuator, and the common processing difficulty is that the clamping is difficult due to the abnormal shape, and the shape of the workpiece is mainly clamped by four claws. After that, turn the vertical hole system. Each workpiece needs four times of clamping bef...

[0003] However, in the existing technology, there are generally recognized technical difficulties in the processing of the cross lug assembly of the electromechanical actuator, and the common processing difficulty is that the clamping is difficult due to the abnormal shape, and the shape of the workpiece is mainly clamped by four claws. After that, turn the vertical hole system

Each workpiece needs four times of clamping before processing, that is, four times of alignment process. The alignment process is complicated, time-consuming and laborious, requires high skill level of the operator, and poor product quality stability

As for how to realize the automatic centering and orientation of the workpiece when clamping, avoid the complicated alignment process of four-jaw clamping, and complete the turning process with high quality, high efficiency and low labor intensity, it is unanimously a difficult problem in the field of machining, and there is no big problem. good solution
