How to ensure the machining accuracy of high precision double disc grinding?

A double disc grinding is a high-efficiency surface machining machine that grinds two parallel surfaces simultaneously in a single machining process. According to the structure can be divided into horizontal and vertical; According to the feed mode of CNC double disc grinding, it can also be divided into through type, rotary type and reciprocating. Due to high precision and high production efficiency, it is widely used in many industries such as automobiles and motorcycles, bearings, magnetic materials and so on. High precision double disc grinding will produce certain vibration during the working process, long-term vibration will not only affect the service life of the equipment, but also affect the processing accuracy.

Our purpose is to provide a high-precision double disc grinding with high processing accuracy, which has the advantage of ensuring accuracy, and solves the problem that the double disc grinding will produce certain vibration during the working process, and the long-term vibration will not only affect the service life of the equipment, but also affect the processing accuracy.

In order to achieve the above purpose, we adopt the following technical solutions: The utility model relates to a high-precision double disc grinding, comprising a base and a platform. The top sides of the base are fixed connected with a box body, one side of the box body is provided with a sliding hole, the top and bottom of the box chamber are fixed connected with a column, the column surface is covered with a No. 1 shock absorber spring, the upper end of the column surface is sliding connected with a sliding sleeve, and one side of the sliding sleeve is fixed connected with a movable rod. The movable rod extends outside the sliding hole and is fixed connected with the frame, the top of the frame is fixed connected with the platform, the bottom of the frame cavity is fixed connected with the arc damping plate, the two sides of the arc damping plate are connected with the limited position ring through the rotating shaft, the surface of the limiting ring is sliding connected with the slide rod, the two ends of the slide rod are covered with a second damping spring, one side of the slide rod is fixed connected with the fixed rod. The fixing rod is fixed to the base. One side of the second shock absorber spring is fixed connected with the limit ring, and the other side is fixed connected with the fixing rod. The bottom of the base is provided with a 1 limit slot, the inner cavity of the 1 limit slot is sliding connected with a 1 limit block, and the top of the 1 limit block is fixed with a finite bit ring. The upper and lower sides of the inner cavity of the first limit slot are provided with a second limit slot, and the inner cavity of the second limit slot is sliding connected with a second limit block, and the side of the second limit block away from the inner cavity of the second limit slot is fixed connected with the first limit block. A third limit slot is arranged on one side of the inner cavity of the box, and a third limit block is sliding connected to the inner cavity of the third limit slot, and a sliding sleeve is fixed on the side of the third limit block far from the inner cavity of the third limit slot.

Compared with the prior art, the high-precision double disc grinding has the following beneficial effects: The limiting ring is moved by the curved damping plate, and the limiting ring squeezes the second damping spring, while the frame drives the movable rod to move, and the movable rod drives the sliding sleeve to slide on the surface of the column, and the sliding sleeve squeezes the first damping spring, so that the second damping spring and the first damping spring are forced to deform, effectively buffering the vibration and avoiding the situation of reducing the machining accuracy due to vibration. It solves the problem that the high-precision double disc grinding will produce certain vibration during the working process, and the long-term vibration will not only affect the service life of the equipment, but also affect the processing accuracy.
