Axial flexible deburring spindle

Abstract

The invention relates to the field of mechanical processing and manufacturing, in particular to an axially flexible deburring main shaft of end face deburring and grinding equipment, including a main shaft, a casing and a cylinder; the main shaft includes an outer sliding shaft and an inner working shaft, and the inner working shaft is rotatably arranged on The outer sliding shaft, the inner working shaft and the outer sliding shaft are rotationally matched; the main shaft is installed in the main shaft installation hole of the casing, and the main shaft slides axially along the main shaft installation hole, and at least two cylinders are installed at the lower end of the casing in a circular array, and the cylinders act simultaneously The outer sliding shaft makes the working end of the inner working shaft play a flexible and self-adaptive role when it contacts the workpiece. The device has a compact and reliable telescopic mechanism, the telescopic mechanism is pneumatically controlled, and the air pressure can be adjusted according to the usage conditions, so as to adjust the elasticity of the telescopic mechanism.

Description

technical field [0001] The invention relates to the field of mechanical processing and manufacturing, in particular to an axially flexible deburring spindle of end face deburring and grinding equipment. Background technique [0002] The workpieces formed at one time by die-casting or mold technology will inevitably produce burrs such as risers and flashes during the production process. In order to avoid affecting the subsequent processing and the quality of the final product, these burrs must be dealt with intensively before the subsequent processing. [0003] Existing automated mechanical deburring devices are divided into rigid deburring devices and flexible deburring devices. Among them, the rigid deburring device is characterized by simple structure and low cost, but the processing effect on workpieces with complex shapes is not good, and it is easy to damage the workpiece; in addition , Due to the inconsistency of the size of the part itself and the size of the flash, ...

Problems solved by technology

[0003] Existing automated mechanical deburring devices are divided into rigid deburring devices and flexible deburring devices. Among them, the rigid deburring device is characterized by simple structure and low cost, but the processing effect on workpieces with complex shapes is not good, and it is easy to damage the workpiece; in addition , due to the inconsistency of the size of the part itself and the flash size, the grinding quality is unstable and the tool is easy to be damaged

If the traditional rigid cutting method is used for grinding parts, the grinding quality cannot be guaranteed, and it will also cause problems such as short tool life and high processing costs.

[0004] Furthermore, there are also workpieces with a certain radian. This kind of workpiece has a radian problem or a certain degree of undulation during grinding. In this case, if a rigid shaft is used to process the workpiece, it may damage the original workpiece The contour changes, so that the equipment cannot reach the original design situation. In this case, a rotating shaft mechanism with a lifting effect is required, so that the workpiece contour can guide the working head to a certain extent, instead of forced grinding, resulting in workpiece contour so change
