Pulley Automatic Tightening Machine

Abstract

The invention discloses an automatic pulley tightening machine, which includes a servo motor, a gear stop mechanism, an in-position sensor, a model identification mechanism, a REID reader, a tray and a jacking mechanism, and also includes a Sliding plate, the changing cylinder on the sliding plate, the servo motor drives the ball screw to move the sliding plate through the coupling, the sliding plate is equipped with a tightening mechanism including the upper limit bolt and the lower limit bolt, and the changing cylinder passes through the upper and lower limit The bolts adjust the height of the pulley corresponding to the HR model or QR model; the RFID reader receives the information from the in-position sensor and the model identification mechanism and transmits the information to the servo motor and the jacking mechanism. The invention adopts automation, can effectively save labor costs, is stable, easy to operate, and can be compatible with various models.

Description

technical field [0001] The invention relates to an automatic tightening machine for pulleys. Background technique [0002] In the engine assembly factory, in some workpiece tightening equipment (tightening bolts, loosening, etc.), when the tightening positions of workpieces of different models are inconsistent, it is often necessary to displace and move the tightening position. The usual method is to install a cylinder Move to the final stop to tighten the bolts. [0003] Such as figure 1 As shown, there is generally a frame 1, and the tightening cylinder 2 (or oil cylinder, gas-liquid booster cylinder, etc.) is installed on the sliding plate 3, and a tightening mechanism is installed on it, and the operator manually operates the handle button 5 to control the movement of the tightening mechanism. At the working position, tighten the 6-rotating sleeve 7 and tighten the cap to drive the pulley to rotate, insert the positioning pin 8 into the technological slot of the pulley...

AI Technical Summary

Problems solved by technology

[0006] 1) Manual operation is prone to fatigue and operational errors;

[0007] 2) High labor cost;

[0008] 3) Use a single model and cannot be compatible with models of different heights

[0010] 1) The use of a single model is not compatible with models of different heights, and the adaptability to product change is poor;

[0011] 2) The movement speed of the tightening mechanism is unstable, and a buffer is needed to control its impact force

A long time is easy to cause damage to the equipment and affect the service life of the equipment
