Automatic adjustment type auxiliary supporting mechanism for tool die

Abstract

The invention relates to an automatic adjustment type auxiliary supporting mechanism for a tool die. The automatic adjustment type auxiliary supporting mechanism comprises a support body, a lifting mechanism and an anti-skid handle. The support body is columnar, and a through hole is formed in the axial middle portion of the support body. The lifting mechanism comprises a central shaft and a spring and is located in the through hole of the support body. One end of the central shaft is a supporting end, and the other end of the central shaft is sleeved with the spring. The central shaft moves vertically relative to the support body. The anti-skid handle is connected to one side of the support body in a threaded mode in the radial direction. The locking end of the anti-skid handle extends into the support body and is in contact with the central shaft to have the locking function. The automatic adjustment type auxiliary supporting mechanism is suitable for any tool die needing auxiliary support, and especially applied to the surface of a workpiece blank with a size error; the automatic adjustment type auxiliary supporting mechanism is also suitable for all the machined surfaces which are far away from main base faces and will generate vibration and deformation under the action of cutting force.

Description

technical field [0001] The invention relates to the technical field of machining, in particular to an auxiliary mechanism for machining fixtures or moulds. Background technique [0002] The torque converter housing is an important part of the forklift, which requires high precision. The blank is cast from gray cast iron, which is a thin-walled hollow cavity with irregular shape. When processing each surface and hole, special tooling is required to position and clamp the workpiece. Due to the large size of the torque converter housing, the blank weighs about 78 kg. In order to avoid vibration and deformation when processing the small flange plane and each hole, it is necessary to add auxiliary support mechanisms in some parts to improve the support rigidity of the workpiece and ensure its processing quality. Therefore, every time the workpiece is clamped, it is necessary to manually move up and down through a wrench to adjust the auxiliary supporting mechanism so that it co...

AI Technical Summary

Problems solved by technology

Due to the casting error in the shape of the casting blank, the height of the auxiliary support mechanism must be readjusted every time the workpiece is loaded and unloaded, which has disadvantages such as low efficiency and high labor intensity. At the same time, there may be hidden dangers of destroying the positioning of the workpiece due to the friction torque driving the workpiece
