Technical Field

[0001] The utility model relates to the technical field of pin sleeve processing, in particular to an automatic measuring fixture in pin sleeve processing. Background Art

[0002] Pin bushings are hardened steel inserts that reinforce the dowel pin holes.

[0003] However, in the existing technology, the structure of the fixture for pin sleeve processing is relatively simple, the fixture has fewer points of action on the pin sleeve, and the surface of the pin sleeve is relatively smooth, which may cause the pin sleeve to deflect during the processing, affecting the precise processing of the pin sleeve. For this reason, we propose an automated measuring fixture for pin sleeve processing. Utility Model Content

[0004] The utility model provides an automatic measuring fixture for pin sleeve processing, which solves the above-mentioned technical problems.

[0005] The solution of the utility model to solve the above technical problems is as follows: an automated measuring fixture for pin sleeve processing, comprising a mounting plate and a fixed plate, the fixed plate being fixedly connected to one end of the mounting plate, the mounting plate being installed with a movable plate through a sliding mechanism, the upper end surface of the movable plate being fixedly installed with a displacement sensor, the fixed plate being connected to the movable plate through a displacement control mechanism, the opposite surfaces of the fixed plate and the movable plate being respectively provided with a fixing groove, a support member being fixedly installed at the lower part of the inner wall of the fixing groove, a first electric push rod being vertically fixedly installed on the upper end surface of the fixed plate or the movable plate, the free end of the first electric push rod being movably passed through the fixed plate or the movable plate, the inner wall of the fixing groove being slidably fitted with a pressing fixing member, and the pressing fixing member being fixedly connected to the free end of the first electric push rod.

[0006] Preferably, the sliding mechanism includes a sliding groove transversely opened on the outer side wall of the mounting plate, and the movable plate is slidingly connected to the inner side wall of the sliding groove.

[0007] Preferably, the displacement control mechanism includes a second electric push rod fixedly installed laterally on the outer side wall of the fixed plate, and the free end of the second electric push rod movably passes through the fixed plate and is fixedly connected to the movable plate.

[0008] Preferably, resistance-enhancing pads are fixedly mounted on the opposing surfaces of the support member and the pressing and fixing member.

[0009] Preferably, connecting plates are vertically fixedly installed at both ends of the mounting plate, and threaded holes are passed through the connecting plates.

[0010] The beneficial effects of the utility model are:

[0011] 1. By setting a second electric push rod to drive the moving plate to move, the fixed plate cooperates with the moving plate to fix the pin sleeve from both ends. At the same time, a support piece and a pressing fixture are set in the fixing groove to cooperate with the pin sleeve to clamp and fix it from the end. The pin sleeve is fixed with multi-point force, and the fixing and clamping of the pin sleeve is more stable. At the same time, the pin sleeve can be clamped and fixed separately by the support piece and the pressing fixture on the fixing plate. One end of the pin sleeve is exposed, and the pin sleeve end can be processed, which makes it more functional.

[0012] 2. By setting a displacement sensor on the upper end surface of the movable plate, the displacement sensor is used to monitor the moving distance of the movable plate, and the displacement sensor is used to monitor and calculate feedback, and the length of the clamped pin sleeve is automatically measured, so that the measured data is more accurate and the error is smaller.

A first electric push rod 7 is vertically fixedly installed on the upper end surface of the fixed plate 2 or the movable plate 3, and the free end of the first electric push rod 7 movably passes through the fixed plate 2 or the movable plate 3. A pressing fixing member 8 is slidably matched with the inner wall of the fixed groove 5, and the pressing fixing member 8 is fixedly connected to the free end of the first electric push rod 7. The device can clamp and fix the end of the pin sleeve through the support member 6 and the extrusion fixing member 8 arranged in the fixed groove 5.
