a fixing mechanism is arranged on the fixing plate 3;
the fixing mechanism comprises a fixing pin 7 matched with the round hole of the motor seat 5, a push plate 8 and a pull rod 9 fixedly connected with the fixing pin 7;
a fixed box 10 is fixed on the fixed plate 3, a through groove 11 matched with the fixed pin 7 is formed in the fixed plate 3, the fixed pin 7 is slidably arranged in the through groove 11, the push plate 8 is slidably arranged in the fixed box 10, a spring 12 is fixedly connected in the fixed box 10, the push plate 8 is abutted against the fixed pin 7 under the action of the spring 12, one end of the pull rod 9 sequentially penetrates through the fixed box 10 and the push plate 8 and is connected to one end of the fixed pin 7, and the other end of the pull rod is positioned outside the fixed box 10;
the spring 12 enables the push plate 8 to abut against the fixing pin 7, the spring 12 has certain elasticity to push a part of the fixing pin 7 out of the through groove 11, and the circular groove 18 is formed in one end of the fixing pin 7, so that the whole weight is not heavy, the elasticity of the spring 12 is not particularly large, and a worker can pull the fixing pin 7 by pulling the pull rod 9;
a part of the fixing pin 7 can be retracted into the fixing box 10, and the part of the fixing pin 7 can be pulled into the fixing box 10 by pulling the pull rod 9, wherein the end surface of the fixing pin 7 is flush with the side surface of the fixing plate 3;
when the motor base 5 is hung above a tool, a worker pulls the pull rod 9 to enable the end face of the fixing pin 7 to be flush with the side face of the fixing plate 3, then the motor base 5 is lowered to one side of the fixing plate 3, then the pull rod 9 is loosened, and the fixing pin 7 is automatically inserted into a round hole of the motor base 5 in the process that the motor base 5 is lowered, so that the motor base 5 is fixed; after welding, pulling the pull rod 9 to enable the end face of the fixing pin 7 to be flush with the side face of the fixing plate 3, so that the riveted and welded crawler beam assembly can be directly hoisted away for processing;
the adjusting mechanism comprises a top plate 13 abutting against the lower side of the motor base 5, a connecting rod 14 hinged to the lower side of the top plate 13, a threaded rod 15 abutting against the bottom of the connecting rod 14 and a fixing sleeve 16 used for limiting the connecting rod 14 to move up and down only;
the fixing sleeve 16 is fixed on one side of the fixing plate 3, a supporting plate 17 is further fixed on one side of the fixing plate 3, and the threaded rod 15 is in threaded connection with the supporting plate 17;
the height of the top plate 13 can be adjusted by rotating the threaded rod 15, a worker can screw the threaded rod 15 through a wrench, the fixing sleeve 16 is sleeved on the connecting rod 14 and limits the connecting rod to move only up and down, the connecting rod 14 is hinged with the top plate 13 so as to increase the contact area of the top plate 13 and the bottom side inclined plane of the motor seat 5 when the motor seat 5 is jacked, the pressure is reduced, the service life is prolonged, in addition, when the track beam 4 and the motor seat 5 of the same specification are riveted and welded, only one adjustment is needed, the top plate 13 is adjusted to the proper height, and then the readjustment is not needed, and the operation is very convenient;
after the fixing is completed, the side end face of the motor base 5 is flush with the side of the fixing plate 3 close to the track beam 4. One end of the crawler beam 4 props against one side of the fixed plate 3, namely the side end face of the motor seat 5, so that accurate positioning is realized, the requirements of drawings are met, and the problems that the crawler beam 4 and the motor seat 5 are inaccurate in position, have errors and cannot meet the integral machining standard when riveted are solved;
furthermore, a circular groove 18 is formed in one end of the fixing pin 7, the length of the circular groove 18 is two thirds of the length of the fixing pin 7, and the weight of the fixing pin 7 is reduced, namely the labor amount of a worker pulling the pull rod 9 is reduced.
Further, a supporting frame 19 is fixedly arranged in the circular groove 18, the supporting frame 19 is triangular, the stability of the triangular supporting frame 19 is improved, and the stress is more uniform.
The working principle is as follows: during the use, hoist motor seat 5 to the frock top earlier, workman pulling pull rod 9 makes the terminal surface of fixed pin 7 flush with the side of fixed plate 3, fall motor seat 5 to one side of fixed plate 3, then loosen pull rod 9, fixed pin 7 is in the in-process automatic insertion motor seat 5's the round hole that descends at motor seat 5, the completion is fixed to motor seat 5, rotate threaded rod 15 through the spanner after that, adjust the height of connecting rod 14 and roof 13, make the side end face of motor seat 5 flush with the side of fixed plate 3, then hang crawler beam 4 to the frock on, the U-shaped part of crawler beam 4 aim at draw-in groove 6 can, rivet welding at last, the welding completion can be hung and walk and go on whole processing.
