Description
Technical field
The present invention relates to a kind of accurate grinding process equipment, grinding machine annex---the deep hole formula adjustable in pressure magnechuck when especially relating to a kind of wheel grinding glass.
Background technology
Glass is applied on a lot of equipment components as a kind of important material more and more widely, and is following, and the processing of glass elements is also just seemed to become more and more important.At present, in the glass grinding manufacture field, utilize electromagnetic worktable usually, hold anchor clamps,, fix tight position, begin a surface of processed glass then with clamp glass to be processed.But, when using the glass optics of the machining large-sized and thinner thickness of this traditional processing mode, devitrified glass for example; Because the glass zone line fully contacts with magnechuck; And fringe region does not have, unbalance stress, and promptly central authorities are stressed bigger; And that the edge is stressed is less, therefore is easy to generate the deformation phenomenon of edge perk.Because the deformation at edge, workpiece to be machined is depressed by emery wheel easily when causing grinding, causes stock removal not enough, has had a strong impact on workpiece face shape and machining accuracy.
Chinese patent CN201020628 discloses a kind of circular electromagnetic chunk of improvement.It can be used as the special fixture of inside and outside circle mill, the inside and outside circle and the end face of circular workpiece of grinding or extraordinary thin wall circular shape workpiece behind the sticking, and machining accuracy is high, and part can not be out of shape because of clamping.It comprises disk body, coil, panel, it is characterized in that: said disk body, panel five equilibrium are separated out sector region, and coil and this regional disk body, panel that each sector region distributes form little magnechuck.
Summary of the invention
The objective of the invention is to be difficult to guarantee glass pieces zone line to be processed and the stressed uniform shortcoming of fringe region to traditional magnechuck; Provide a kind of in the clamp workpiece; Workpiece rim zone also can effectively be attracted on the sucker, can cooperate grinding machine to accomplish the deep hole formula adjustable in pressure magnechuck of the accurate grinding of glass pieces.
The present invention is provided with magnechuck and anchor clamps, on magnechuck, is provided with magnechuck fringe region hole, magnechuck zone line, the 1st aspirating hole and the 2nd aspirating hole; Magnechuck fringe region hole is distributed in around the edge on the magnechuck symmetrically; And be connected with the 2nd aspirating hole in bottom, magnechuck fringe region hole; Said magnechuck is provided with four limits, every limit corresponding a row hole, a said row hole in the bottom of magnechuck through the 2nd aspirating hole UNICOM; Be connected on the aspiration pump the also corresponding magnechuck inside that is distributed in symmetrically and evenly of the 2nd aspirating hole by the 2nd aspirating hole; Said magnechuck zone line hole also is distributed in the zone line of magnechuck symmetrically, in bottom, magnechuck zone line hole a connected region is set, and said connected region and the 1st aspirating hole UNICOM also are connected on the aspiration pump.
The size of said magnechuck can be 500mm * 500mm; The size of said anchor clamps can be 300mm * 40mm; The diameter in said magnechuck fringe region hole can be Φ 20mm, and the size of said zone line can be Φ 20mm, and the aperture of said the 1st aspirating hole and the 2nd aspirating hole all can be Φ 20mm.The degree of depth in said magnechuck fringe region hole can be the half the of magnechuck height, and the degree of depth in said magnechuck zone line hole can be 2/3rds of magnechuck height.
Said anchor clamps can be the magnetic material anchor clamps.
Owing to adopt above technical scheme, so the present invention has following outstanding advantage:
1) the present invention is used for wheel grinding and adds man-hour, and magnechuck is to the clamping of glass pieces.Utilize aspiration pump can bleed,, guarantee that the edge can perk, finally guarantee machining accuracy so that processed glass pieces firmly inhaled on magnechuck to magnechuck fringe region hole and magnechuck zone line hole.
2) when a certain limit of wheel grinding processed glass workpiece four edges, the pressure that this limit receives is bigger, is not easy perk; And other easy perks in three limits; So the present invention designs in four limits of magnechuck, every limit corresponding a row hole, this row hole in the bottom through the 2nd aspirating hole UNICOM; And can be connected on the aspiration pump by the 2nd aspirating hole; The also corresponding magnechuck inside that is distributed in symmetrically and evenly of the 2nd aspirating hole so just can realize that the hole on every limit can work alone through aspiration pump, realizes the adjusting of pressure.
3) when wheel grinding processed glass workpiece; The zone line of workpiece so be not easy perk, is provided with a connected region so the present invention designs in bottom, magnechuck zone line hole owing to fully contact with magnechuck; By the 1st this join domain of aspirating hole UNICOM; Separate connection can realize the pressure adjusting like this to aspiration pump, save the material and the energy.
4) magnechuck fringe region hole and magnechuck zone line hole independent separately, be independent of each other, so can select whether to use together or use some according to concrete actual conditions.
