FIG. 1 is a schematic structural view of the present invention;

as shown, 1 sander, 2 transition plates, 3 sliders, 4 linear guides, 5 support plates, 6 bolts, 7 clamping seats, 8 workpieces, 9 baffles, 10 crossed roller bearings, 11 sander lower clamps, 12 sander upper clamps.

Detailed Description

As shown in the figure, the utility model relates to an automatic grinding device, which mainly comprises the following components: sander 1, transition plate 2, support plate 5, sander upper clamp 12, sander lower clamp 11, cross roller bearing 10, linear guide 4, and clamp shoe 7.

And a clamping seat is vertically arranged on the inner ring at the lower part of the crossed roller bearing, three groups of clamping heads are arranged on the inner side of the clamping seat, a bolt 6 penetrates from the outer side of the clamping seat to be connected with the clamping heads, and the clamping heads can clamp a workpiece 8 by rotating the bolt. The method comprises the following steps that a support plate is transversely fixed on an outer ring on the upper surface of a crossed roller bearing, linear guide rails are fixedly installed on the upper surface of the support plate and on two sides of the crossed roller bearing respectively through bolts, a sliding block 3 is installed at one end of each linear guide rail, and the sliding blocks move along the linear guide rails; and a baffle 9 is arranged at the end part of the linear guide rail, and the baffle is fixed on the support plate to prevent the sliding block from sliding out of the support plate.

A transition plate is transversely fixed on the upper surface of the sliding block, the transition plate and the sliding block are fixed through bolts, and the transition plate moves along with the sliding block; the upper part and the lower part of the middle part of the transition plate are respectively fixedly provided with an upper clamp of a grinding machine and a lower clamp of the grinding machine; the sander is in an electrically controlled sander model, which is KU770B, and has one end passing vertically through an upper sander clamp and a lower sander clamp, which are fastened together by tightening screws, and a sanding head mounted coaxially at the end, which is detachably mounted on the sander. The polishing head is contacted with the end part of the workpiece.
