DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1-4 A planetary gear shaft assembly tool shown includes a workbench 101 and an auxiliary mechanism. A clamping mechanism is provided at the top of the workbench 101. The planetary gear is fixed at the top of the workbench 101 by the clamping mechanism. The wheel shaft is then positioned by the auxiliary mechanism. The auxiliary mechanism then drives the wheel shaft down until it is inserted into the planetary gear to complete the assembly.

[0024] In a preferred embodiment, an auxiliary mechanism is arranged above the workbench 101, and the auxiliary mechanism includes an insert cylinder 201. A plurality of extrusion rings 202 are arranged in a circular array inside the insert cylinder 201. A spring 203 is arranged between the extrusion ring 202 and the inner wall of the insert cylinder 201. A connecting mechanism is arranged between the extrusion ring 202 and the insert cylinder 201. A guiding mechanism is arranged at the bottom end of the extrusion ring 202. The wheel axle is inserted into the insert cylinder 201, and then through the elastic action of the plurality of springs 203, the plurality of extrusion rings 202 squeeze the outer wall of the wheel axle, so that the wheel axle can be preliminarily positioned in the insert cylinder 201, so that the insert cylinder 201 can drive the wheel axle to descend when it descends, and the operator does not need to hold the wheel axle by hand, thereby improving the safety of operation.

[0025] Among them, the connecting mechanism includes a movable rod 301, one end of which is fixedly connected to the outer wall of the extrusion ring 202, and a movable hole 302 is opened on the inner wall of the insert tube 201. The outer wall of the movable rod 301 and the inner wall of the movable hole 302 are movably connected and inserted, and the spring 203 is sleeved on the outer wall of the movable rod 301. Through the mutual limitation of the movable rod 301 and the movable hole 302, the movable rod 301 can only move in the movable hole 302, so that the extrusion ring 202 can only move in a specific direction, thereby improving the stability of the extrusion ring 202. At the same time, the movable rod 301 can limit the spring 203, so that the spring 203 will not be longitudinally deformed when compressed, thereby improving the stability of the spring 203.

[0026] Among them, the guiding mechanism includes a guide plate 401, the top end of the guide plate 401 is fixedly connected to the bottom end of the extrusion ring 202, and the guide plate 401 is arranged at an angle. When the wheel axle is inserted into the insert tube 201, the wheel axle will squeeze multiple guide plates 401, thereby moving the extrusion ring 202 until the wheel axle is inserted between the multiple extrusion rings 202, thereby improving the convenience of operating the auxiliary mechanism.

[0027] Among them, the top of the workbench 101 is fixedly connected to a fixed frame 501, and a telescopic cylinder 502 is installed on the top of the fixed frame 501. The output end of the telescopic cylinder 502 passes through the top of the fixed frame 501 and is transmission-connected to the top of the insert cylinder 201. The insert cylinder 201 can be driven down by the operation of the telescopic cylinder 502, so that the wheel axle positioned in the insert cylinder 201 can be lowered for assembly, thereby improving the convenience of assembly work. The telescopic cylinder 502 is electrically connected to an external power supply through an external switch, which is convenient for the operator to control the telescopic cylinder 502, thereby improving the safety and convenience of the operation of the telescopic cylinder 502.

[0028] Among them, the clamping mechanism includes a plurality of clamping blocks 601, a plurality of slide grooves 602 are opened at the top of the workbench 101, and a slider 603 is slidably connected to the inner wall of the slide groove 602. The top of the slider 603 is fixedly connected to the bottom end of the clamping block 601. The planetary gear is placed on the top of the workbench 101, and then the corresponding clamping block 601 is driven to move by the movement of the slider 603 until the plurality of clamping blocks 601 are against the planetary gear, thereby completing the positioning of the planetary gear, so that the subsequent assembly work can be carried out stably.

[0029] Among them, the workbench 101 is internally rotatably connected with a rotating plate 701, and a plurality of guide grooves 702 are opened at the top of the rotating plate 701. A connecting shaft 703 is slidably provided on the inner wall of the guide groove 702. The top of the connecting shaft 703 is fixedly connected to the bottom end of the slider 603. By rotating the rotating plate 701 and cooperating with the guide groove 702 and the connecting shaft 703, the rotation of the rotating plate 701 can drive a plurality of clamping blocks 601 to move simultaneously, thereby achieving the effect of centering and clamping the planetary gear at the top of the workbench 101, so that the center of the planetary gear can be aligned with the insert cylinder 201, which is convenient for inserting the wheel axle into the planetary gear.

[0030] Among them, a worm wheel 801 is fixedly sleeved on the outer wall of the rotating plate 701, and a worm 802 is rotatably connected to the inner wall of the workbench 101. The outer wall of the worm 802 is meshed with the outer wall of the worm wheel 801. One end of the worm 802 passes through the inner wall of the workbench 101 and is fixedly connected to a turntable 803. A handle 804 is provided on the side of the outer wall of the turntable 803. The worm wheel 801 can be driven to rotate by rotating the worm 802, thereby rotating the rotating plate 701. The lead angle of the worm 802 is smaller than the equivalent friction angle between the meshing teeth of the worm wheel 801, so that the worm 802 and the worm wheel 801 are self-locking. Only the rotation of the worm 802 can drive the worm wheel 801 to rotate. Through the cooperation of the turntable 803 and the handle 804, the turntable 803 can be rotated by holding the handle 804, thereby improving the convenience of operating the worm 802.
