Description

Motor rotor core press-fitting tool Technical Field The utility model relates to the technical field of rotor core press-fitting, in particular to a motor rotor core press-fitting tool. Background In the press mounting process of the motor rotor core, the suitability of a supporting block for supporting the rotor core is poor, when the rotor core of different types is replaced, a connecting piece at the bottom of equipment is required to be disassembled, the operation is complicated and time-consuming, the production efficiency is seriously affected, the stability of the supporting block after the installation is insufficient, the positioning deviation is easily caused by vertical or horizontal sliding in the press mounting process, the press mounting precision is affected, even the rotor core or a mandrel is damaged, and the connection reliability of the supporting block is poor when the supporting block is frequently replaced in a high-frequency press mounting or vibration environment. These problems restrict the efficiency and the precision of the press fitting of the motor rotor core, and are difficult to meet the production requirements of large scale and multiple types. Disclosure of utility model Based on this, it is necessary to provide a motor rotor core press-fitting tool to solve the problems in the prior art. In order to solve the problems in the prior art, the utility model adopts the following technical scheme: The utility model provides a motor rotor iron core press-mounting tool which comprises a bottom plate and a mounting frame arranged on the bottom plate, wherein a workpiece supporting block is arranged on the bottom plate, a press is arranged on the mounting frame, a press mounting head is arranged at the output end of the press, the press mounting head is positioned right above the workpiece supporting block, the workpiece supporting block consists of a base, a quick-dismantling seat and a in-place abutting seat, a first mounting hole fixedly connected with the base is arranged on the bottom plate, a central groove is arranged at the center of the base, the in-place abutting seat is detachably arranged in the central groove, a mounting ring is arranged at the top of the base, a ring groove matched with the mounting ring is arranged at the bottom of the quick-dismantling seat, a limit guide groove is arranged on the outer side wall of the mounting ring, a first limit block sliding in the limit guide groove is arranged in the ring groove, a bolt horizontally sliding with the mounting ring is also arranged at the outer side of the quick-dismantling seat, and a multi-stage bearing step is arranged at the center of the quick-dismantling seat. In order to prevent the quick-release seat from vertical sliding when the quick-release seat and the base are in press-fitting operation after being mounted above the base, the press-fitting precision is affected, one end opening of the limiting guide groove is communicated with the top of the mounting ring, the limiting guide groove extends downwards along the arc of the outer side wall of the mounting ring from the top end of the mounting ring, and a horizontal groove is communicated with the bottom of the groove. Preferably, slots which are horizontally arranged are arranged on the outer side wall of the quick-release seat and the mounting ring, and the bolt is in locking connection with the outer side wall of the quick-release seat. In order to further improve the locking connection effect of the quick-release seat and the base, the quick-release seat is prevented from being deviated from the base in the horizontal direction and the vertical direction, the cross section of the bolt is rectangular, and the shape of the slot is completely consistent with that of the bolt. Because the bolt is in the horizontal insertion slot, in order to avoid the bolt to slide out from the slot in the horizontal direction, need be connected with quick detach seat with the slot, the bolt is kept away from the one end rotation in quick detach seat center and is connected with the column spinner, and the tip of column spinner is equipped with screws up the seat, column spinner and quick detach seat lateral wall threaded connection. In the first embodiment, one end of the bolt, which is far away from the center of the quick-release seat, is provided with an elastic metal plate symmetrically arranged in a V shape, the outer side wall of the elastic metal plate is provided with a locking column, and the quick-release seat is provided with a locking hole matched with the locking column. Because the locking relation of bolt and quick detach seat can be realized in the first embodiment, but threaded connection's state makes it comparatively loaded down with trivial details when the dismouting, needs rotatory enough number of turns just can realize the effect of installation or dismantlement, in order to improve dismouting efficiency under the stable prerequisite of guaranteei
