Heavy adjustable rotary mechanical arm for pressing and method

Abstract

The invention belongs to the field of machine manufacturing, particularly relates to a heavy adjustable rotary mechanical arm for pressing and a method, and provides the following scheme aiming at the problem of insufficient means in the prior art: the heavy adjustable rotary mechanical arm comprises a base, a main arm, a support arm and a lock mechanism, the base comprises a support, a rotating shaft sleeve with an oil groove and a nut with a shoulder, the base is connected with one end of the main arm through a rotating shaft sleeve with an oil groove, the other end of the main arm is provided with a U-shaped opening, one end of the supporting arm and the lock mechanism are wrapped in the U-shaped opening of the main arm, the design of brand new technological equipment embodies the mechanical/non-mechanical interaction requirement, switching between a pneumatic locking mode and a mechanical locking mode is provided for the mechanical arm in the working state, and the mechanical arm is convenient to use. And the failure risk after the mechanical arm presses the workpiece is eliminated, and the manual operation risk in the workpiece machining process is reduced. The process equipment is obvious in effect after being used and verified in a workshop, and the manufacturing requirements of products are met.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a heavy-duty adjustable rotary mechanical arm and method for pressing. Background technique [0002] In the mechanical processing industry, positioning and pressing are indispensable technological means in the process of workpiece processing and forming. After the workpiece is accurately positioned, it needs to be pressed to ensure the continuity, stability and durability of the machining process, which can effectively avoid machining errors or even scrapping caused by tool vibration or other human factors. For complex structures or large-sized workpieces, the operating space is often limited during the production process, and the construction access is narrow or difficult to reach by manpower. Therefore, reasonable and effective clamping has become one of the technical difficulties in the machining industry. [0003] The clamping method of the workpiece can be ...

AI Technical Summary

Problems solved by technology

During the welding process, the usual compression method is to select the pressure plate to cooperate with the screw pair to compress the workpiece, or to compress the workpiece through a wedge-shaped structure. In actual production, there are several deficiencies: the workpiece needs manual force during the compression process, and the process is cumbersome. The tight point is unstable, which can easily lead to the small displacement of the workpiece during the pressing process and is difficult to measure; (2) For large-sized workpieces, there are many pressing points, and the operation is difficult when the clamping plate needs to be clamped before processing, and at least two to three people are required Collaborative cooperation, high dependence on the operator's experience, and high labor intensity; (3) For welding workpieces with complex structures, the pressing components need to be manually disassembled before and after welding, which leads to low production efficiency. Protection, there is a certain danger in the operation of workers; (4) The fixing and pressing of the workpiece is completely controlled by manpower. Affected by the proficiency of the operation, the uneven force on the surface of the workpiece is prone to deformation or indentation

(5) During the long-term processing of the workpiece, the screw clamping element is easily affected by the vibration of the tool or equipment, and the clamping force cannot be kept constant and there is a risk of falling out
