Description

Technical Field

[0001] The utility model relates to the technical field of pin processing equipment, in particular to a positioning device for pin processing. Background Art

[0002] Pins are a type of standardized fastener that can be used for static fixed connections or for relative movement with the connected parts. They are mainly used at the hinge joints of two parts to form hinge connections. Pins are usually locked with cotter pins, which ensure reliable operation and easy disassembly.

[0003] According to the search, Chinese patent document, announcement number: CN215881414U, discloses a positioning device for pin shaft processing, wherein the sliding plate drives the slider to move upward along the slide groove, and the slider can push the support rod and the first clamping plate upward, and at the same time push the two support arms to rotate so that the top ends of the two support arms are close to each other, and the two second clamping plates and the first clamping plate can clamp the pin shaft to maintain the stability of the pin shaft, and the support arms are pushed by setting a reset spring so that the top ends of the two support arms are away from each other to release the pin shaft, which is convenient for removing the pin shaft after processing is completed. By setting a control device, rotating the control wheel can drive the sliders of the two clamp boxes to move up and down, which is convenient for controlling the two second clamping plates and the first clamping plate to clamp and release the pin shaft, and can cope with pin shafts of different sizes. By setting a latch pin and a pin hole, the control wheel can be fixed and no longer rotated. In summary, the device can clamp pin shafts of different sizes, making the positioning operation convenient, reducing the positioning time of the pin shaft, improving the processing efficiency of the pin shaft, and ensuring the positioning effect of the pin shaft. However, during the installation of the axle pin, it is impossible to accurately locate the fixed positions of the two ends of the axle pin, resulting in time-consuming manual adjustment of the clamping distance and the inability to ensure that the clamping position is accurate. At the same time, the fixed control wheel no longer rotates through the bayonet and the pin hole, resulting in the pin hole that needs to be fixed not being guaranteed to be the same as the base plate socket when fixing different axle pins, which may easily cause the pin to become loose after being fixed later, making it impossible to fix the axle pin.
