A push-pull auxiliary support device

Abstract

The invention discloses a push-pull type auxiliary supporting device. The push-pull type auxiliary supporting device comprises a pedestal arranged horizontally; a cylinder body which is arranged vertically upwards is arranged on the top surface of the pedestal; a gear cavity is formed in the right side of the lower part of the cylinder body; a vertical lower top column is arranged in the cylinderbody; a vertical groove is formed in the left side of the bottom of the lower top column; a vertical rack is arranged on the right side of the bottom of the lower top column; a spring is arranged on the outer side of the middle part of the lower top column; a pin arranged transversely is arranged at the relative position of the top of the lower top column; a jackscrew arranged transversely is arranged at the relative position of the left part of the cylinder body; a gear is rotatably arranged in the gear cavity; a handle is fixedly arranged on the front side surface of the gear; an upper top column is arranged on the upper part of the lower top column; and a long hole is transversely formed at the relative position of the upper top column. The push-pull type auxiliary supporting device has the beneficial effects of capability of providing support for a processing piece, simple structure and convenience in operation.

Description

technical field [0001] The invention belongs to the technical field of auxiliary supporting devices, and in particular relates to a push-pull auxiliary supporting device. Background technique [0002] In the machining process, the workpiece itself is affected by factors such as its shape, size or machine tool structure, and the parts to be processed are occasionally in a suspended state, which will lead to poor processing stability and rigidity, and affect the machining accuracy of the workpiece. At this time, it is necessary to Adding auxiliary supports at the bottom of the workpiece solves the problem. [0003] At present, most of the commonly used auxiliary supports are pads, which cannot be adjusted in height. Most of the structures that can adjust the height are screw structures. During use, the height is adjusted manually. The operation is cumbersome, the workload is large, and the influence of human factors may cause damage to the workpiece. Damage, for this reason, ...

[0002] In the machining process, the workpiece itself is affected by factors such as its shape, size or machine tool structure, and the parts to be processed are occasionally in a suspended state, which will lead to poor processing stability and rigidity, and affect the machining accuracy of the workpiece. At this time, it is necessary to Adding auxiliary support at the bottom of the workpiece to solve the problem

[0003] At present, most of the commonly used auxiliary supports are pads, which cannot be adjusted in height. Most of the structures that can adjust the height are screw structures. During use, the height is adjusted manually. The operation is cumbersome, the workload is large, and the influence of human factors may cause damage to the workpiece. Damage, for this reason, people have been looking for new workpiece support devices
