Description

Technical Field

[0001] The utility model belongs to the technical field of rubber bushing processing, in particular to an edge grinding device for rubber bushing processing. Background Art

[0002] The rubber bushing is a matching part used outside of mechanical parts to achieve the functions of sealing and wear protection. It refers to a ring sleeve that acts as a gasket. In the field of valve applications, the bushing is inside the valve cover and is generally made of corrosion-resistant materials such as polytetrafluoroethylene or graphite for sealing. With the increasing use of rapid rubber bushings in the automotive industry, the appearance requirements are becoming more and more stringent. The outer side of the current rubber bushing is relatively rough and not smooth enough due to production process problems. It is not only unsightly, but also affects the use effect of other related parts of the car. In the existing technology, the rubber bushing to be polished is usually clamped by an adding mechanism, and then the rubber bushing is polished by a polishing mechanism. However, when the rubber bushing is clamped by the clamping mechanism, the clamping force is too small, and the rubber bushing is easily not fixed firmly and falls off. If the clamping is too tight, the rubber bushing will deform, affecting the production quality of the rubber bushing. In addition, the existing technology is not convenient for removing the polished rubber bushing from the clamping mechanism. Utility Model Content

An upper support frame is fixed to the right end of the upper support beam, and a rotating shaft is rotatably assembled on the upper support frame. A vertically arranged rotating motor is fixed to the upper support frame above the rotating shaft, and a power output shaft of the rotating motor is transmission-connected to the upper end of the rotating shaft. A horizontally arranged lower support beam is provided below the upper support frame, and the top end of the lower support beam is fixed to the bottom end of the rotating shaft. When the rotating motor is started, the power output shaft of the rotating motor drives the lower support beam to rotate through the rotating shaft. The bottom of the lower support beam is provided with a guide groove, in which a lead screw is arranged parallel to the lower support beam. Both ends of the lead screw are rotatably assembled on the lower support beam, and a lead screw motor is provided at one end of the lower support beam. The power output shaft of the lead screw motor is connected to the lead screw. A sliding rod arranged parallel to the lead screw is fixed in the guide groove above the lead screw. Both ends of the sliding rod are fixed to the lower support beam. The lead screw is threaded with a first support block and a second support block arranged symmetrically. The internal threads of the first and second support blocks are opposite, and the upper ends of the first and second support blocks are slidably connected to the sliding rod. When the lead screw motor is started, the power output shaft of the lead screw motor rotates clockwise, and the lead screw pushes the first and second support blocks to move toward each other along the sliding rod, bringing the first and second support blocks closer together. When the power output shaft of the lead screw motor rotates counterclockwise, the first and second support blocks move away from each other.

When in use, the rubber bushing to be polished is put on the outside of the air bag, and then the air bag is inflated by an air pump. After the air bag is expanded, the rubber bushing is fixed on the air bag. Since the burrs on the surface of the rubber bushing to be polished are small, the rubber bushing will not rotate or twist under the friction of the grinding stone. After the grinding is completed, the gas in the air bag is released to facilitate the removal of the rubber bushing.

[0004] Preferably, the inflation and deflation mechanism includes an air pump fixed to the top of the support platform, and a connecting pipe is provided between the air pump and the inflation pipe.
