How to ensure the machining accuracy of high-precision double-end grinding machine
The double-sided grinding machine is a high-efficiency plane processing machine tool, which grinds two parallel surfaces at the same time in one processing process. According to the structure can be divided into horizontal and vertical; according to the CNC double-sided grinder feed mode, can also be divided into through, rotary and reciprocating. Due to its high precision and high production efficiency, it is widely used in many industries such as automobiles and motorcycles, bearings, and magnetic materials.High-precision double-face grinding machineA certain amount of vibration will be generated 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-end grinding machine with high machining accuracy, which has the advantage of ensuring accuracy. It solves the problem that the double-sided grinding machine will produce certain vibration during the working process. Long-term vibration not only affects the service life of the equipment, but also affects The problem of processing accuracy.
In order to achieve the above purpose, we adopt the following technical scheme: aHigh-precision double-face grinding machine, Including a base and a platform. The top two sides of the base are fixedly connected with a box body, one side of the box body is provided with a sliding hole, the top and bottom of the box cavity are fixedly connected with a column, the surface of the column is sleeved with a first damping spring, and the surface of the column The upper end is slidably connected with a sliding sleeve, and one side of the sliding sleeve is fixedly connected with a movable rod. The movable rod extends to the outside of the sliding hole and is fixedly connected with the frame. The top of the frame is fixedly connected with the platform. The bottom of the inner cavity of the frame is fixedly connected with an arc damping plate. Both sides of the arc damping plate are movably connected with a limiting ring through a rotating shaft. The surface of the limiting ring is slidably connected with a sliding rod. Both ends of the sliding rod surface are covered with a second damping spring. One side of the sliding rod is fixedly connected with the fixing rod. One side of the second damper spring is fixedly connected to the limit ring, and the other side is fixedly connected to the fixing rod. The bottom of the base is provided with a first limit groove, the inner cavity of the first limit groove is slidably connected with a first limit block, and the top of the first limit block is fixedly connected with a limit ring. Two sides of the upper end and two sides of the lower end of the inner cavity of the first limit groove are provided with a second limit groove, the inner cavity of the second limit groove is slidably connected with a second limit block, and the side of the second limit block away from the inner cavity of the second limit groove is fixedly connected with the first limit block. One side of the inner cavity of the box body is provided with a third limit groove, the inner cavity of the third limit groove is slidably connected with a third limit block, and the side of the third limit block away from the inner cavity of the third limit groove is fixedly connected with a sliding sleeve.
Compared with the existing technology,High-precision double-face grinding machineIt has the following beneficial effects: the arc-shaped damping plate drives the limit ring to move, the limit ring presses the second damping spring, the frame drives the movable rod to move at the same time, the movable rod drives the sliding sleeve to slide on the surface of the upright column, and the sliding sleeve presses the first damping spring, so that the second damping spring and the first damping spring are deformed under force, effectively buffering vibration, and avoiding the reduction of processing accuracy due to vibration. It solves the problem that the high-precision double-end grinder 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.
The above is the high-precision double-end grinding machine related content is introduced, hoping to help you.
