A double-drive double-guide pull-up type internal broaching machine

Abstract

The invention discloses a double-drive double-guide-rod pull-up type internal broaching machine, which comprises a bed with guide columns connected to both sides; The guiding structure can be raised and lowered along the guide pillars. The two guide pillars are respectively arranged on the left and right sides of the processing hole. The first driving device is connected to the two sides of the first slide plate, which can drive it to move up and down along the guide pillars. The first driving device is located on the axis of the guide pillars. In the vertical plane formed together with the axis of the processing hole; the lifting and feeding device is arranged above the first slide plate, and the lifting and feeding device is detachably connected with a broach, which can drive the broach to move up and down relative to the first slide plate so that the broach can extend into the Processing holes. According to the double-drive double-guide rod pull-up type internal broaching machine provided by the present invention, the force application point of the drive device, the fulcrum of the guide column, and the processing force point are symmetrically distributed on the same plane to avoid overturning torque, and improve the machining accuracy and stability of the workpiece. Reduce equipment loss.

Description

technical field [0001] The invention relates to the field of vertical broaching machines, in particular to a double-drive double-guide rod pull-up type internal broaching machine. Background technique [0002] At present, with the improvement of the customer's requirements for the process precision of the workpiece to be processed and the strong demand for highly automated matching of equipment, it is particularly important to develop a machine tool that is highly compatible with the automation requirements of a modern factory and has better machining accuracy and stability. . In the inherent structure of the existing equipment, the overturning moment will be generated because the driving force, the fulcrum of the guide rail, and the processing force point are not in the same plane, so that the workpiece will not only overcome its own deformation during processing, but also be affected by the deformation of the equipment, affecting the processing of the workpiece Accuracy a...

In the inherent structure of the existing equipment, the overturning moment will be generated because the driving force, the fulcrum of the guide rail, and the processing force point are not in the same plane, so that the workpiece will not only overcome its own deformation during processing, but also be affected by the deformation of the equipment, affecting the processing of the workpiece Accuracy and Stability

Moreover, the knife lifting device in the traditional equipment lacks an anti-falling device, resulting in a high failure rate and insufficient risk avoidance
