Problems solved by technology
After the process is completed, the flatness of the parts meets the process requirements, but the parallelism still does not meet the technical requirements. In addition, the process needs to be dried for 30 to 50 minutes after the glue is applied. After grinding one side, be careful to scrape off Superglue, then apply glue, dry glue, and repeat many times, the efficiency is extremely low

Embodiment Construction
[0017] Such as figure 1 As shown, a surface grinding method for circular sheet parts with glue-free technology, for the MG7363 horizontal surface grinder, at least three magnetizable positioning stops 3 are prepared first, and the positioning stops 3 can be magnetized and then installed, or Directly install it on the grinding machine table 2 with magnetization function and then magnetize it. When at least three positioning blocks are fixed, one positioning block A3-1 does not contact the workpiece, and the other positioning blocks 3 are surrounded by the periphery of the workpiece and the workpiece. touch.
[0018] Put a ring-shaped auxiliary positioning part (such as a small bearing ring) of appropriate size between the circular sheet workpiece (referred to as the workpiece) and the positioning stopper A3-1. The ring-shaped auxiliary positioning part is a rigid annular ring structure, and the ring-shaped auxiliary positioning The size of the part should be greater than the m...

The invention provides a circular thin-sheet part plane grinding method without an adhesive process. According to circular thin-sheet part plane grinding method, at least three magnetized positioningstop blocks are fixedly arranged on the periphery of a circular thin-sheet workpiece placed on a nonmagnetic grinder workbench; a ring-shaped auxiliary positioning part is placed between the positioning stop block A and the circular thin-sheet workpiece, and the positioning stop block A is prevented from being in contact with the circular thin-sheet workpiece; the ring-shaped auxiliary positioningpart is positioned on the side opposite to the rotating direction of the grinder workbench; the outer surface of the ring-shaped auxiliary positioning part is in contact with the positioning stop block A and the circular thin-sheet workpiece; the other positioning stop blocks cling to the outer circumference of the circular thin-sheet workpiece; a grinding wheel is started so as to ensure that the rotating trend of the circular thin-sheet workpiece is opposite to the rotating direction of the grinder workbench; and the ring-shaped auxiliary positioning part is clamped between the positioningstop blocks and the circular thin-sheet workpiece till the grinding operation is completed. By adoption of the circular thin-sheet part plane grinding method, the influence of a strong magnetic forceon the workpiece grinding precision can be avoided; the inefficient adhesive process can be discarded and the technological machining demand can be met; and furthermore, the machining efficiency can be remarkably improved as well as both the manpower and material resources can be saved.
Description
technical field [0001] The invention relates to a grinding process, in particular to a method for surface grinding of circular thin slice parts with an adhesive-free process. Background technique [0002] At present, for surface grinding of sheet bearing parts, magnetic grinding or viscose grinding is generally used. During magnetic grinding, the parts need to be adsorbed on the magnetic workbench. Since such parts are thin, the ratio of diameter to thickness is large, and the rigidity is poor, elastic deformation will inevitably occur under the action of strong magnetic force. Therefore, the flatness of the parts The degree of peace is still difficult to meet the process requirements. [0003] The viscose grinding process uses superglue to stick thin parts on the grinding table to make them precisely positioned, and then grinds repeatedly on both sides. After the process is completed, the flatness of the parts meets the process requirements, but the parallelism still does...
