Detailed Description

The first embodiment is given by figures 1-4, the utility model discloses a L template 1, go up briquetting 2 and briquetting 3 down, it all establishes in L template 1 inboard to go up briquetting 2 and briquetting 3 down, it establishes at briquetting 3 top down to go up briquetting 2, there is first bracing piece 4 bottom briquetting 3 bottom down through bearing swing joint, 4 bottom of first bracing piece and the 1 inboard bottom fixed connection of L template, briquetting 3 bottom is equipped with positioning mechanism down, just positioning mechanism extends L template 1 bottom, L template 1 inboard is equipped with adjustment mechanism, it all establishes in adjustment mechanism one side to go up briquetting 2 and briquetting 3 down, goes up briquetting 2 and briquetting 3 down and all designs conically, and an area that is close to the finding is less, can occupy less area when the fixed finding of centre gripping can, more conveniently carry out the centre gripping to finding fixed.

Adjustment mechanism includes fixed block 13, fixed block 13 fixed connection is on 1 inside wall of L template, fixed block 13 top is run through and is equipped with threaded rod 14, just fixed block 13 and threaded rod 14 pass through bearing swing joint, it has second bracing piece 12 to go up 2 tops of briquetting through bearing swing joint, the fixed fly leaf 11 that is equipped with in second bracing piece 12 top, threaded rod 14 runs through fly leaf 11, and adjustment mechanism is adjustable goes up briquetting 2 and the distance between the briquetting 3 down to be convenient for carry out the centre gripping to unidimensional small-size part and fix.

The movable plate 11 is connected with the threaded rod 14 through threads, one side, far away from the second supporting rod 12, of the movable plate 11 is in contact with the inner side wall of the L-shaped plate 1, the movable plate 11 is in contact with the inner side of the L-shaped plate 1, the movable plate 11 cannot rotate along with the rotation of the threaded rod 14 when moving along the threaded rod 14, and the movable plate 11 is guided and limited and can only move up and down along the threaded rod 14.

The bottom end of the threaded rod 14 is movably connected with the bottom end of the inner side of the L-shaped plate 1 through a bearing, a rotating wheel 15 is fixedly arranged at the top end of the threaded rod 14, the rotating wheel 15 is arranged at the top of the fixed block 13, and the rotating wheel 15 is convenient to rotate the threaded rod 14 manually.

Embodiment two, on the basis of embodiment one, positioning mechanism includes connecting plate 6, connecting plate 6 is established in L template 1 bottom, the fixed two inserted bar 7 that are equipped with in connecting plate 6 top, inserted bar 7 runs through L template 1 bottom and extends to L template 1 inboard, just L template 1 and inserted bar 7 sliding connection, a plurality of round holes 5 have been seted up to briquetting 3 bottom down, inserted bar 7 is established in briquetting 3 bottom down and extends to inside adjacent round hole 5, first bracing piece 4 is established between two inserted bars 7, the outer pot head of inserted bar 7 is equipped with fender ring 8 and spring 9, inserted bar 7 and fender ring 8 fixed connection, spring 9 both ends respectively with 8 bottoms of fender ring and the inboard bottom of L template 1 fixed connection, when polishing and grinding the small-size part, because lower briquetting 3 receives positioning mechanism's restriction, therefore briquetting 3 and last briquetting 2 all can not rotate with the small-size part by the centre gripping at will, when removing positioning mechanism's restriction, because last briquetting 2 and lower briquetting 3 respectively with second bracing piece 12 and the small-size part polishing and the angle adjustment mechanism can be held at will be through the last briquetting 2 and the last pressing and the small-size part that can be processed once more, therefore the angle adjustment mechanism is good through the last briquetting 3 that can be processed and the polishing and the small-size pressing piece can be continued with the angle adjustment mechanism again.

The bottom end of the connecting plate 6 is fixedly provided with a pull ring 10, and the pull ring 10 is convenient for fingers to pull so as to relieve the limitation of the positioning mechanism on the lower pressing block 3.

The working principle is as follows:

firstly, a small part is placed between an upper pressing block 2 and a lower pressing block 3, then a rotating wheel 15 is screwed by hand to enable a threaded rod 14 to rotate, the threaded rod 14 is connected with a movable plate 11 through threads, one side of the movable plate 11, which is far away from a second supporting rod 12, is contacted with the inner side wall of an L-shaped plate 1, therefore, the movable plate 11 can move downwards along with the rotation of the threaded rod 14, the movable plate 11 can drive the upper pressing block 2 to move downwards synchronously through the second supporting rod 12 when moving downwards until the small part is clamped between the upper pressing block 2 and the lower pressing block 3 to be fixed for subsequent polishing and grinding processing, after one side or one end of the small part is polished and ground, a pull ring 10 can be pulled by hand, at the moment, a connecting plate 6 can move downwards along with the pull ring 10 and drive an inserted rod 7 to be separated from a round hole 5, during the period, the spring 9 is compressed and generates elastic force, the inserted bar 7 is pulled out from the round hole 5, then the lower pressing block 3 is not limited, therefore, the small parts clamped between the upper pressing block 2 and the lower pressing block 3 can follow the upper pressing block 2 and the lower pressing block 3 to rotate and adjust the direction, one surface or one end which is not polished and polished is enabled to turn to the outside, the pulling pull ring 10 is stopped after the angle is adjusted, at the moment, the elastic force of the spring 9 can push the baffle ring 8 to move upwards to restore the original position, the baffle ring 8 can drive the inserted bar 7 to synchronously move when moving upwards, the inserted bar 7 is inserted into the corresponding round hole 5 again to position the lower pressing block 3, so that the upper pressing block 2, the lower pressing block 3 and the clamped small parts cannot rotate any more, and then polishing and polishing can be continued.
