Referring to fig. 1-4, the present invention provides an embodiment: a clamping tool for tightening a bulldozer crawler comprises a base 1, a supporting table 3, a movable block 6 and clamping blocks 7, wherein the supporting table 3 is arranged at the top end of the base 1, a threaded rod 5 is arranged at the middle position inside the supporting table 3, the movable block 6 is arranged at the top end of the supporting table 3, the bottom of the movable block 6 is sleeved outside the threaded rod 5, the clamping blocks 7 are arranged at the top end of the supporting table 3 and the bottom end of the movable block 6, an adjusting block 8 is arranged at the middle position of the bottom end of the supporting table 3, the top end of the adjusting block 8 penetrates through the outer wall of the supporting table 3 and extends to the inside to be fixedly connected with the threaded rod 5, dismounting structures 2 are arranged at two sides of one end of each clamping block 7, each dismounting structure 2 comprises a fixed block 201, a fixed rod 202, clamping grooves 203 and clamping blocks 204, the clamping blocks 204 are fixed at two sides of one end of each clamping block 7, clamping grooves 203 are arranged at two sides of the bottom end of each movable block 6 and two sides of the top end of the supporting table 3, a clamping block 204 is inserted into the clamping groove 203, the fixed blocks 201 are fixed on the two sides of the support table 3 and the movable block 6, a fixed rod 202 is inserted into the middle position of the inside of the fixed block 201, and one side of the fixed rod 202 extends into the clamping groove 203 and is inserted into the clamping block 204;

an internal thread is arranged inside the fixing block 201, an external thread is arranged outside the fixing rod 202, and the fixing block 201 and the fixing rod 202 form a thread structure;

when the clamping block 7 needs to be replaced, a worker only needs to rotate the fixing rod 202, and the fixing block 201 and the fixing rod 202 form a thread structure, so that the fixing rod 202 can be separated from the inside of the clamping block 204 under the action of the fixing block 201, when the fixing block 201 is completely separated from the inside of the clamping block 204, the clamping block 7 can be detached by separating the clamping groove 203 from the clamping block 204, and replacement can be performed at the moment;

a rotating structure 9 is arranged at the middle position inside the base 1, the rotating structure 9 comprises a rotating block 901, a movable groove 902, a supporting block 903 and an annular sliding groove 904, the movable groove 902 is arranged at the middle position inside the base 1, the rotating block 901 is arranged inside the movable groove 902, the top end of the rotating block 901 is fixed at the middle position of the bottom of the supporting table 3, the annular sliding groove 904 is arranged inside the base 1, the supporting block 903 is fixed on both sides of the top end of the supporting table 3, and the supporting block 903 is arranged inside the annular sliding groove 904;

the longitudinal section of the supporting block 903 is smaller than that of the annular chute 904, and the supporting block 903 and the annular chute 904 form sliding connection;

because the rotating block 901 is in sliding connection with the movable groove 902, a worker can adjust the processing direction only by rotating the supporting table 3, meanwhile, the supporting block 903 can rotate in the annular sliding groove 904, the supporting block 903 plays a further supporting role for the supporting table 3, and the processing angle can be adjusted by rotating, so that the processing is more convenient;

the scrap iron prevention structures 4 are arranged on two sides of the top end inside the supporting platform 3, each scrap iron prevention structure 4 comprises an installation block 401, a blocking brush 402, a convex block 403 and a groove 404, the installation blocks 401 are arranged on two sides of the top end inside the supporting platform 3, the blocking brush 402 is fixed on one side of each installation block 401, the convex blocks 403 are fixed on two ends of the other side of each installation block 401, the grooves 404 are formed in the supporting platform 3, and the convex blocks 403 are inserted into the grooves 404;

the outer diameter of the bump 403 is smaller than the inner diameter of the groove 404, and the bump 403 and the groove 404 form a clamping structure;

carry out the processing to bull-dozer track through the staff and can produce a large amount of iron fillings and dust, separation brush 402 can prevent to add a large amount of iron fillings that produce and the surface that the dust falls into threaded rod 5 man-hour, long-term back when using, can pull down separation brush 402 and clear up, the staff only need drag and draw installation piece 401, separate lug 403 and recess 404's block, can pull down separation brush 402 and clear up this moment, through the separation effect of separation brush 402 to iron fillings and dust, indirect threaded rod 5 of having solved leads to the card to die to be difficult to the pivoted problem because of iron fillings and dust are too much when rotating.

The working principle is as follows: firstly, a large amount of scrap iron and dust can be generated when a worker processes a bulldozer crawler, the blocking brush 402 can prevent a large amount of scrap iron and dust generated in the processing from falling onto the surface of the threaded rod 5, the blocking brush 402 can be detached for cleaning after being used for a long time, the worker only needs to pull the mounting block 401 to separate the clamping of the convex block 403 and the groove 404, at the moment, the blocking brush 402 can be detached for cleaning, and the problem that the threaded rod 5 is blocked due to excessive scrap iron and dust and is difficult to rotate when rotating is indirectly solved through the blocking effect of the blocking brush 402 on the scrap iron and dust;

then, a worker places the bulldozer crawler to be machined on the support table 3, the locking rod is connected with the adjusting block 8, the adjusting block 8 is rotated, the adjusting block 8 drives the threaded rod 5 to rotate, the threaded rod 5 is sleeved outside the threaded rod 5 due to the bottom of the movable block 6, and the threaded rod 5 is in threaded connection with the movable block 6, so that under the action of the threaded rod 5, the movable block 6 moves to the position where the bulldozer crawler is located, the crawler is clamped through the clamping block 7, when machining is conducted, the rotating block 901 is in sliding connection with the movable groove 902, the worker can conduct adjustment of the machining direction only by rotating the support table 3, meanwhile, the support block 903 can rotate inside the annular sliding groove 904, the support block 903 plays a role in further supporting the support table 3, and machining is more convenient due to the fact that machining angle is adjusted through rotation;

finally, when clamp splice 7 need be changed, the staff only need rotate dead lever 202, because fixed block 201 and dead lever 202 constitute the helicitic texture, so dead lever 202 can break away from the inside of fixture block 204 under the effect of fixed block 201, after fixed block 201 breaks away from the inside of fixture block 204 completely, the block between draw-in groove 203 and the fixture block 204 is separated and clamp splice 7 can be dismantled, change this moment can, during the installation, the staff only need with draw-in groove 203 and fixture block 204 block, utilize dead lever 202 to carry out the fixed to fixture block 204 can, convenient dismouting has not only saved a large amount of time, and can prevent to utilize the screw fixation to lead to producing smooth silk after the long time of screw use.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
