[0023] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.
[0024] Please refer to Figures 2 to 4 As shown, the utility model is an eccentric wheel assembly tool for a massager transmission shaft, comprising an eccentric wheel placement component 1, a transmission shaft placement block 2 and a linear reciprocating device 3; the eccentric wheel placement component 1 comprises a fixed portion 11 and a movable portion 12 arranged opposite to each other, and an eccentric wheel profiling hole 4 is arranged on a side surface of the fixed portion 11 facing the movable portion 12 and a side surface of the movable portion 12 facing the fixed portion 11;
[0025] The transmission shaft placement block 2 is slidably arranged between the fixed part 11 and the movable part 12, and a rotating shaft placement groove 21 and an avoidance groove 22 are arranged on the top of the transmission shaft placement block 2. The opening direction of the rotating shaft placement groove 21 is perpendicular to the side of the fixed part 11 where the eccentric wheel profiling hole 4 is arranged, and the opening direction of the avoidance groove 22 is perpendicular to the opening direction of the rotating shaft placement groove 21;
[0026] The linear reciprocating device 3 has a movable end that moves vertically toward a side of the fixed portion 11 provided with the eccentric wheel profiling hole 4 , and the movable end of the linear reciprocating device 3 is connected to the movable portion 12 .
[0027] The linear reciprocating device 3 is preferably a cylinder, and the movable end thereof is a piston rod of the cylinder.
[0028] Working principle: The transmission shaft placement block 2 is slidably arranged between the fixed part 11 and the movable part 12 of the eccentric wheel placement assembly 1. Since the top of the transmission shaft placement block 2 is provided with a rotating shaft placement groove 21 and an avoidance groove 22, the rotating shaft 71 of the transmission shaft 7 can be placed in the rotating shaft placement groove 21, and the gear 72 of the transmission shaft 7 is placed in the avoidance groove 22, so as to stably store the transmission shaft 7. At the same time, since the fixed part 11 and the movable part 12 are both provided with eccentric wheel profiling holes 4, the staff can place the eccentric wheel 8 on the fixed part 11 and the movable part 12 according to the required posture, so as to ensure that the axis of the assembly hole on the eccentric wheel 8 coincides with the axis of the rotating shaft 71 located on the transmission shaft placement block 2. Finally, the linear reciprocating device 3 is used to drive the movable part 12 to push the transmission shaft placement block 2 toward the fixed part 11, and finally, the two eccentric wheels 8 are assembled on the rotating shaft 71 under the limit of the fixed part 11.
[0029] Please refer to Figure 2 and Figure 4As shown, further, the eccentric wheel assembly of the above-mentioned massager transmission shaft also includes a slide rod mounting block 5 and a slide rod 6, the slide rod mounting block 5 is arranged on the side of the movable part 12 away from the fixed part 11, and the two ends of the slide rod 6 along its own length direction are respectively connected to the fixed part 11 and the slide rod mounting block 5, and the transmission shaft placement block 2 and the movable part 12 are slidably arranged on the rod body of the slide rod 6.
[0030] As can be seen from the above description, the sliding of the transmission shaft placement block 2 and the movable part 12 is ensured by the sliding rod 6 in the sliding direction, so as to ensure that during the assembly process, the axis of the rotating shaft 71 is coaxial with the axis of the assembly hole on the eccentric wheel 8.
[0031] Please refer to Figure 2 and Figure 4 As shown, further, a return spring 61 is sleeved on the rod body of the slide rod 6 , one end of the return spring 61 abuts against the fixing portion 11 , and the other end of the return spring 61 abuts against the transmission shaft placement block 2 .
[0032] From the above description, it can be seen that after the assembly is completed, the linear reciprocating device 3 drives the movable part 12 to reset, thereby disengaging the eccentric wheel 8 located on the movable part 12, and at the same time the reset spring 61 drives the transmission shaft mounting block 2 away from the fixed part 11, thereby disengaging the eccentric wheel 8 located on the fixed part 11, and then the worker can remove the assembled massager transmission shaft from the transmission shaft mounting block 2.
[0033] Please refer to Figure 2 and Figure 4 As shown, further, a pressure strip 23 is hinged on the top of the transmission shaft placement block 2, a hook 231 is swingably provided at the free end of the pressure strip 23, and a protrusion 24 engaged with the hook 231 is provided on the transmission shaft placement block 2.
[0034] From the above description, it can be seen that after placing the transmission shaft 7 into the transmission shaft mounting block 2, the worker presses the operating strip 23 onto the shaft body of the rotating shaft 71, and limits the movement of the strip 23 through the cooperation of the hook 231 and the protrusion 24 to ensure that the rotating shaft 71 will not move during the process of being assembled into the assembly hole of the eccentric wheel 8.
[0035] Please refer to Figure 3 As shown, further, the pressure strip 23 is provided with a groove 232 corresponding to the shaft placement groove 21 .
[0036] It can be seen from the above description that the pressure strip 23 can better contact the shaft body of the rotating shaft 71 through the groove 232, thereby ensuring the pressing effect of the pressure strip 23 on the rotating shaft 71.
