Preferably, the piston of the cylinder is connected with a connecting rod, the connecting rod is far away from one end of the fixed seat, the pressure plate is arranged on the end, far away from the fixed seat, of the connecting rod, and the pressure plate is made of nylon. Adopt the nylon material, prevent to push down the in-process and cause the damage to the end cover, influence the outward appearance.

Furthermore, a sliding groove is formed in the fixing seat, and a piston of the air cylinder is arranged in the sliding groove.

Preferably, the connecting rod is provided with a mounting hole, the pressure plate is provided with a T-shaped hole, and the T-shaped hole is fixedly connected with the mounting hole through a bolt.

Furthermore, two positioning holes are formed in the positioning column, two bolts are arranged on the limiting block, and the bolts are matched and fixed with the positioning holes. The stopper can be dismantled, when the installation, pull down the stopper earlier, puts the casing in the assigned position, then passes through the bolt with the stopper and inserts in the locating hole, then puts into the end cover until contacting with the motor casing directly over the stopper again.

Preferably, a clamping groove is formed in the middle of the limiting block, and the shape of the clamping groove corresponds to that of the mounting plate on the motor end cover. The clamping groove limits the left-right rotation of the end cover, so that the end cover can only move up and down, and the position of a hole in the end cover is ensured to be corresponding to that of a hole in the shell.

Further, the stopper is the L type, be equipped with on the stopper and be used for placing the groove of stepping down of fixed plate on the motor casing.

Has the advantages that: the utility model has the advantages of simple structure, convenient operation drive the pressure disk through the cylinder and push down the motor end cover, and the atress is even, has improved the efficiency of assembly greatly, and labour saving and time saving adopts spacing block structure simultaneously, has ensured the uniformity of hole position on hole and the casing on the end cover, and the position of casing has been ensured to the reference column, has guaranteed the accuracy in the assembling process.

Detailed Description

Example one

As shown in the figure, a motor end cover assembly fixture, includes base 1, be equipped with fixing base 2 on the base 1, be equipped with cylinder 3 on the fixing base 2, be connected with pressure disk 4 that is used for compressing tightly motor end cover 9 on the piston of cylinder 3, be equipped with two reference columns 5 on the base 1 at least, it has stopper 6 that is used for restricting motor end cover 9 pivoted to peg graft on the reference column 5, still be equipped with on the reference column 5 be used for with casing 10 on the locating hole 15 complex locating pin 7.

The piston and the connecting rod 8 of cylinder 3 are connected, connecting rod 8 keeps away from the one end of fixing base 2 is equipped with pressure disk 4, pressure disk 4 material is nylon. The fixed seat 2 is provided with a sliding groove 11, and the piston of the cylinder 3 is arranged in the sliding groove 11. The connecting rod 8 is provided with a mounting hole 12, the pressure plate 4 is provided with a T-shaped hole 14, and the T-shaped hole 14 and the mounting hole 12 are fixedly connected through a bolt and a nut.
