Problems solved by technology

The existing grinding and polishing treatment of the pin shaft is usually to transfer the pin shaft to the processing position through the conveyor belt, and then manually take out the pin shaft and place it in the fixture for positioning, and then grind or polish the pin shaft. The existing problem is that the pin shaft is completed manually Loading and unloading, low work efficiency

Abstract

The invention discloses an automatic clamping mechanism used for polishing a pin shaft, which is used for improving the work efficiency of surface processing of the pin shaft. The automatic clamping mechanism comprises a pendulum block which can be driven by power to rotate to and fro in a vertical plane, wherein the upper part of the pendulum block is a convex arc-shaped sliding table and a feed chute which is located in one side of the convex arc-shaped sliding table; an outlet of a stock bin is provided with an arc section which has the same curvature with the convex arc-shaped sliding table; the surface of the convex arc-shaped sliding table is abutted against the outlet of the stock bin and can swing along the outlet; the feed chute can be swung to the position under the outlet; one side of the pendulum block is provided with a push rod which can do reciprocating linear and horizontal motion; a spring collet is arranged on the other side of the pendulum block; and the push rod can push the pin shaft in the feed chute into the spring collet.

Description

technical field [0001] The invention relates to the processing technology of agricultural machine parts, in particular to an automatic clamping mechanism for pin grinding. Background technique [0002] The pin shaft is a kind of standardized fastener, which can be statically fixed and connected, and can also move relative to the connected parts. It is mainly used at the hinge of two parts to form a hinge connection. For the micro tillage machine in the existing agricultural machinery, the connection between the rotary tiller and the main shaft adopts a pin shaft, and the pin shaft is usually locked with a cotter pin, which is reliable in operation and easy to disassemble. In the processing of the pin shaft, in order to ensure the processing quality of the pin shaft, the surface of the pin shaft needs to be treated before the finished product, usually by grinding and polishing. The existing grinding and polishing treatment of the pin shaft is usually to transfer the pin shaf...
