In order to ensure better transmission, the rotating shaft of the prior art often connects the end of the rotating shaft to the motor power shaft. However, this connection method requires the motor to be disassembled when disassembling the rotating shaft, which increases the labor intensity and reduces production efficiency.

[0003] Therefore, in order to facilitate the disassembly of the rotating shaft and ensure the stability of the connection between the motor power shaft and the rotating shaft, it is necessary to improve the combined components to improve production efficiency. Utility Model Content

[0004] The utility model provides a quick-joining assembly of a rotating shaft and a motor shaft, which can solve the technical problem of the prior art that the inconvenience of disassembly and installation reduces the production efficiency.

[0007] The docking device includes an L-shaped mounting plate, a U-shaped adjusting rod, a sliding plate, a docking rotating shaft and a fixed shaft sleeve. The L-shaped mounting plate is fixed on the side wall of the adjustable base; the U-shaped adjusting rod is rotatably connected to the L-shaped mounting plate; the sliding plate is slidably connected to the L-shaped mounting plate; the motor is fixed on the sliding plate; the fixed shaft sleeve is fixed on the clamping device, and the docking rotating shaft is arranged in the fixed shaft sleeve;

[0008] A push block is arranged on the inner wall of the U-shaped adjusting rod; a motor shaft docking groove is opened at the axis center of the end face of one end of the docking rotating shaft, a plurality of grooves are arranged on the inner wall of the motor shaft docking groove, a rotating shaft docking groove is opened in the middle of the other end of the docking rotating shaft, and a limiting screw is arranged circumferentially on the outer side of the rotating shaft docking groove; a plurality of protrusions which can match the plurality of grooves arranged on the side wall of the motor shaft docking groove are arranged circumferentially on the outer surface of the motor shaft end of the motor, and a pushing groove which can resist the push block arranged on the inner wall of the U-shaped adjusting rod is arranged circumferentially on the outer surface of the motor shaft.

[0009] Beneficial effects:

[0010] 1. The clamping device can be used to clamp the fixed sleeve. The docking shaft is arranged in the fixed sleeve to ensure that the docking shaft is effectively connected to the motor shaft and the rotating shaft, and prevent the docking shaft from being crushed by the clamping device, thereby causing an unstable connection between the motor shaft and the rotating shaft.

[0011] 2. The adjustable base can effectively adjust the axial position of the clamping device, so that when the motor shaft and the rotating shaft are docked using the docking shaft, the motor shaft, the docking shaft and the rotating shaft can be effectively docked, thereby avoiding the problem of unstable connection caused by excessive gaps between the three.

[0012] 3. The docking device utilizes a U-shaped adjusting rod to be rotatably connected with an L-shaped mounting plate, a sliding plate to be slidably connected with the L-shaped mounting plate, and a motor to be fixed on the sliding plate, so that when the U-shaped adjusting rod is pushed counterclockwise, its push block contacts the inner wall of the pushing groove in the circumferential direction of the outer surface of the motor shaft, thereby pushing the sliding plate to move toward the docking shaft, and utilizing a plurality of protrusions provided at the end of the motor shaft to fit with a plurality of grooves provided at the end of the docking shaft to achieve connection between the motor shaft and the docking shaft;

[0013] The rotating shaft is connected to the rotating shaft docking groove at the other end of the docking shaft, and is fixed by a limit screw arranged in the circumference of the rotating shaft docking groove;

[0020] Beneficial effects: The rotating disk can rotate the driving gear column, thereby driving the driven gear column meshing with the driving gear column to rotate, and further driving the axial movement of the limit base; and the limit handwheel can effectively limit the rotation of the driving gear column. When the position of the limit base needs to be fixed, tightening the limit handwheel can prevent the axial movement of the limit base.

[0021] Furthermore, the driven gear column includes a driven shaft and a driven gear and a conversion gear respectively arranged at both ends of the driven gear.

The locking mechanism includes a rocker arm and a locking handwheel. The rocker arm is rotatably connected to the inner wall of the limiting groove. An external thread is arranged at the end of the rocker arm, and the locking handwheel is threadedly connected to the rocker arm.

[0028] Beneficial effects: The limiting groove can be used to accommodate and fix the swing rod, and is also conducive to locking the pressure block and the limiting base by locking the hand wheel.

[0029] Furthermore, the push block is a rotating wheel rotatably connected to the U-shaped adjusting rod.

[0030] Beneficial effect: Setting the push block as a rotating wheel can reduce the friction between the push block and the circumferential outer surface of the motor shaft. BRIEF DESCRIPTION OF THE DRAWINGS
