Please refer to fig. 1 to 5:
the invention provides a centerless grinder supporting plate convenient to replace, which comprises a base plate 1 and a working plate 2, wherein each part of the centerless grinder supporting plate convenient to replace is described in detail as follows:
the upper end of the bottom plate 1 is provided with a plurality of slots 101, the upper end of the left side surface of the bottom plate 1 is provided with a sliding groove 102 and an adjusting groove 103, the adjusting groove 103 is positioned right below the sliding groove 102, the working plate 2 is positioned at the top of the bottom plate 1, the left side surface of the lower end of the working plate 2 is uniformly welded with a plurality of inserting blocks 3, the inserting blocks 3 are inserted into the slots 101, the left end of each inserting block 3 is provided with a wedge hole 301, and the wedge holes 301 are inserted into the wedges 4;
specifically, the slot 101 may be inserted into the insertion block 3 of the working plate 2, so that the working plate 2 may be mounted on the top of the base plate 1, and then the wedge 4 is inserted into the insertion block wedge hole 301, so that the insertion block 3 may be fixed in the insertion hole 101, and the working plate 2 is also fixed on the top of the base plate 1, while the sliding groove 102 may enable the wedge 4 to slide up and down on the left side surface of the base plate 1, and the adjustment groove 103 may adjust the elastic force of the spring 6;
according to the above, the upper end inside the sliding chute 102 is slidably connected with the first sliding block 5, the lower end inside the sliding chute 102 is slidably connected with the second sliding block 7, the spring 6 is fixedly connected between the first sliding block 5 and the second sliding block 7, the left side surface of the first sliding block 5 is welded with the wedge 4, the inside of the adjusting groove 103 is connected with the lead screw 8 through threads, the bottom of the lead screw 8 is welded with the rotating handle 801, and the upper end of the lead screw 8 upwards penetrates into the lower end inside the sliding chute 102;
specifically, the first sliding block 5 can slide up and down in the sliding groove 102, and the wedge 4 welded on the left side surface of the first sliding block 5 can synchronously slide up and down together, when the wedge 4 slides down, the wedge 4 can be separated from being inserted into the wedge hole 301, and the inserting block 3 can be drawn out of the inserting groove 101;
when the lead screw 8 rotates upwards, the lead screw 8 can push the second slider 8 to slide upwards, so that the second slider 8 can compress the spring 6, the compressed spring 6 can generate larger elastic force, and the elastic force can enable the first slider 5 and the wedge 4 to have a trend of moving upwards, so that when the working plate 2 works, if a gap is generated between the wedge hole 301 and the wedge 4 and is loosened, the wedge 4 moves upwards due to the elastic force of the spring 6, and the gap can be automatically filled by the upwards-moving wedge 4, so that the anti-loosening effect is achieved;
and when needing to dismantle the working plate 2 from the bottom plate 1, only need rotate lead screw 8 down earlier for spring 6 elasticity reduces, then promote wedge 4 with the hand and slide down and withdraw from wedge hole 301, later can dismantle the working plate 2 from the bottom plate 1, dismantle convenient and fast, and be convenient for change working plate 2.
The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention.
