AI Technical Summary
Technical Problem
The existing compressor crankshaft clamping process is time-consuming, labor-intensive, and unsafe, requiring operators to manually support and gradually approach the ejector pin mechanism.
Method used
Design an auxiliary positioning device for compressor crankshaft, including a connecting seat, a dual-position cylinder and a standard positioning block. The positioning block is driven to rise and fall by the cylinder to achieve rapid positioning and clamping. Accurate positioning is ensured by matching the fixed-length column with the tapered hole.
Benefits of technology
It improves clamping efficiency, enhances safety, ensures positioning accuracy and concentricity, and avoids the inconvenience and potential dangers of manual operation.

Abstract
The utility model provides an auxiliary positioning device for a compressor crankshaft, which comprises a connecting seat, a double-station cylinder is arranged on the connecting seat, a cylinder rod of the double-station cylinder is connected with a connecting block, the connecting block is connected with a standard positioning block, the standard positioning block comprises a block body, and the top surface of the block body is provided with an arc-shaped recess matched with the outer wall of the compressor crankshaft. When the double-station air cylinder stretches out, the standard positioning block is jacked up, at the moment, the compressor crankshaft is placed on the arc-shaped concave position of the standard positioning block, one end of the compressor crankshaft abuts against the ejector pin mechanism on one side, the axis of the compressor crankshaft is aligned with the ejector pin mechanism on the other side, a shielding door of machining equipment is closed, and the equipment is started. And the ejector pin mechanism on the other side can movably abut against the other end of the compressor crankshaft, so that clamping can be rapidly completed, the working efficiency is improved, when the compressor crankshaft is placed into equipment, all parts in the equipment do not act, and safety is higher.
