Description

CRB cage pneumatic clamp chamfering tooling

technical field

The utility model relates to the design of a universal clamp machine for chamfering and deburring a cage, in particular to a pneumatic clamp chamfering tool for a CRB cage, and belongs to the field of mechanical design.

Background technique

At present, the chamfering quality of the CRB cage is poor, and manual chamfering is generally used for deburring. Chamfering with a machine requires secondary clamping, and there are many models, which require a lot of tooling, and accurate positioning is required for use. Finding alignment and centering is limited by the skill level of personnel, so it is difficult to find alignment and centering. Coordinates need to be reset each time, wasting time. CRB cage chamfering is easy to deform when chamfering the workpiece due to the large chamfering milling force.

Contents of the invention

In view of the defects in the above-mentioned technologies, the purpose of this utility model is to provide a CRB cage pneumatic clamp chamfering tool, which can realize automatic centering and is not affected by the size of the workpiece; the pneumatic cylinder is used for positioning and clamping, which can effectively prevent milling and chamfering. The workpiece is loose; the supporting plate supports the tooling to prevent the workpiece from tilting when chamfering, increasing the stability; the clamping time is short, linkage can be realized, the action is reliable, and the operation is convenient.

In order to achieve the above purpose, the technical solution adopted by the utility model is: CRB cage pneumatic clamp chamfering tooling, including: pneumatic positioning mechanism, cylinder, pressurizing device, automatic centering clamping mechanism and cage; the cage is set on On the self-centering clamping mechanism, the cage is concentric with the self-centering clamping mechanism, with the self-centering clamping mechanism as the center, three pressure devices are connected through connecting rods, and the other ends of the three pressure devices are respectively equipped with cylinders , There is a pneumatic positioning mechanism outside the cage.

The CRB cage pneumatic clamp chamfering tool also includes three support plates, and each support plate is fixedly connected to the lower end surface of the cage;

The pneumatic positioning mechanism is provided with a claw hook, and the claw hook of the pneumatic positioning mechanism is fixed to one end of the support plate outside the cage through a fixing pin;

The support plate is elliptical, with the central point of the support plate as the reference, the area of the support plate inside the cage is the same as the area outside the cage;

The support plate is arranged on the cage between every two adjacent pressing devices;

The included angle between each two adjacent support plates and the center of the self-centering clamping mechanism is 120 degrees.

The specific working process of the CRB cage pneumatic clamp chamfering tool:

Assemble the cage with the automatic centering clamping mechanism of the chamfering tooling, perform preliminary centering on the workpiece, rotate and position the workpiece after centering, and determine the position of the first hole; then set the pneumatic positioning mechanism outside the cage to the The workpiece is clamped externally; after clamping, it is clamped again by three cylinders to prevent the workpiece from being deformed due to excessive clamping force; finally, internal clamping is carried out in the cage by a pressure device, and three auxiliary supports are added to prevent the workpiece from tilting , the pneumatic positioning mechanism retreats, and the processing starts.

The beneficial effects of the utility model are:

This tooling can not only realize the automatic centering of the workpiece, but also prevent the loosening of the milling and chamfering workpiece; the inner and outer three points are clamped at the same time, and the inner and outer three points are clamped at the same time to prevent the deformation of the workpiece due to excessive clamping force; the clamping time is short, and the linkage and action can be realized Reliable; not affected by the tolerance of the inner diameter of the workpiece, high reliability; the range of processed workpieces is 180-700, only the middle support rod needs to be replaced; the coordinate system of the workpiece remains unchanged each time, which is convenient for operation; it is not limited by the level of personnel and operators ;Easy for programming, chamfering is not restricted by gland.
