Problems solved by technology

When using this kind of elastic positioning pin for positioning, if the worker does not pay attention when clamping the workpiece, it is easy to produce waste products. The main reason is that the worker cannot see the positioning pin when clamping the workpiece, and the workpiece is easy to press the elastic pin 1 to the bottom. The elastic pin 1 does not enter the positioning hole, but the workpiece can touch the three positioning supports. In this way, the elastic positioning pin has no positioning function, and the workers cannot see this situation. In this way, all the processed workpieces are scrapped, and it is easy to cause knife collision. In severe cases, it will affect the accuracy of the machine tool

Abstract

The invention relates to an elastic locating pin comprising an elastic pin, a pin seat, an adjusting bolt and a spring; the elastic pin is matched in the pin seat in a sliding mode and protrudes out of one end of the pin seat; the other end of the pin seat is fixedly provided with a limiting screw cap; the adjusting bolt is screwed in the limiting screw cap; and the spring is assembled between the adjusting bolt and the elastic pin. According to the invention, the limiting screw cap is additionally arranged at the end of the pin seat, when the elastic pin does not enter a locating hole of a workpiece, the limiting screw cap can stop the elastic pin from being pressed to the bottom, a worker can discover that the workpiece is not clamped in situ in time, in this way, the elastic pin can be enabled to enter the locating hole of the workpiece so as to locate the workpiece reliably.

Description

technical field [0001] The invention relates to a fixture in the machinery industry, in particular to an elastic positioning pin. Background technique [0002] The elastic positioning pin plays a positioning role in batch processing of castings. Generally speaking, when processing the first process of castings, three points on one side plus two elastic positioning pins are often used for positioning, and the tapered surface of the elastic positioning pins is used for centering. [0003] Existing elastic locating pins such as figure 1 As shown, it includes elastic pin 1, pin seat 2, adjusting screw 6 and spring 7. Elastic pin 1 is slidably fitted in pin seat 2. Adjusting screw 6 is threaded on pin seat 2. Between adjusting screw 6 and elastic pin 1 Equipped with a spring 7, the elastic pin 1 protrudes from the pin seat 2 under the action of the spring 7. When using this kind of elastic positioning pin for positioning, if the worker does not pay attention when clamping the ...
