Description

Technical Field

[0002] Cylindrical workpieces are an important part of metallurgical industrial products. However, due to the influence of raw materials, processes, operations, circulating water cooling, and power supply systems during the smelting process, surface defects such as wrinkles, scars, and threads will form on the surface. In subsequent forging processes, the surface defects of cylindrical workpieces will affect the quality of subsequent products.

[0003] At present, in metallurgical enterprises at home and abroad, there are mainly two methods for surface cleaning and grinding of cylindrical workpieces: one is manual grinding by workers holding a manual grinding wheel. This method has a large labor intensity for grinding cylindrical workpieces, low grinding efficiency, and the grinding is not clean; the other is to use a crane or a cantilever crane to lift a suspended grinding wheel, and the worker operates the suspended grinding wheel to grind the cylindrical workpiece. Compared with the first method, this method is more labor-saving, but the moving position of the grinding wheel is limited, and the cylindrical workpiece needs to be manually flipped, which has certain safety hazards. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art and provide an automatic grinding device for the surface of a cylindrical workpiece, which realizes automatic grinding of the cylindrical workpiece and solves the problem of shortage of personnel at the grinding station.

[0005] The technical solution of the utility model is realized as follows: an automatic grinding device for the surface of a cylindrical workpiece, comprising a frame, a traveling track installed on the frame and parallel to the axis of the cylindrical workpiece, a traveling mechanism bracket reciprocating along the traveling track, a traveling mechanism arranged on the traveling mechanism bracket and driving the traveling mechanism bracket to reciprocate along the axis of the cylindrical workpiece, a grinding mechanism arranged on the traveling mechanism for grinding the cylindrical workpiece, and a pneumatic mechanism for pushing the grinding mechanism close to the cylindrical workpiece;

[0006] The grinding mechanism includes a grinding wheel installed on a base and a grinding wheel motor fixed on the base and connected to the grinding wheel through a transmission belt;

[0007] The pneumatic mechanism includes a linear bearing guide rail arranged on the traveling mechanism bracket, a base movably installed on the linear bearing guide rail, and a cylinder arranged between the linear bearing guide rail and the base. One end of the cylinder for adjusting the position of the grinding mechanism to make the grinding wheel close to the cylindrical workpiece is fixed on the linear bearing guide rail, and the other end is connected to the base;

[0008] The traveling mechanism includes a traveling motor fixed on the traveling mechanism bracket and wheels connected to the traveling motor through a speed reducer and a transmission shaft.

[0009] The grinding wheel machine uses a grinding wheel piece with a specification of 400*40*127 as the grinding piece, and the grinding wheel machine motor is a 1.1KW variable-frequency motor; the traveling motor is a 1.1KW three-phase asynchronous motor with adjustable speed and torque.

[0010] The grinding wheel machine motor drives the grinding wheel machine to rotate through a transmission belt to grind the surface of the cylindrical workpiece. The air cylinder pushes the base to ensure that the grinding piece of the grinding wheel machine always adheres tightly to the surface of the cylindrical workpiece. The traveling motor drives the whole grinding machine to move. The automatic grinding machine travels on the traveling track, and limits are installed at both ends of the traveling track. When the grinding machine touches the limits on both sides, a signal is given to reverse the traveling motor to realize the reciprocating motion. The cylindrical workpiece is placed on the flipping fixture to drive the cylindrical workpiece 12 to rotate.

[0011] The positive effects produced by the technical solution of the present utility model are as follows: Compared with the existing equipment, the device of the present utility model is more fast and efficient. During the grinding process, there is no need for workers to operate manually. Only the position of the cylindrical workpiece, the speed of the automatic grinding machine, and the traveling stroke need to be adjusted before grinding to realize the automatic grinding of the cylindrical workpiece, reduce the grinding workload, effectively save the time required for grinding the cylindrical workpiece, simplify the work process, and improve the grinding efficiency. On the other hand, the components of the device are simple, easy to process and assemble, have strong compatibility, high practical value, and are conducive to market promotion.
