Figure 1 As shown in the figure, a transmission gear needs to be assembled on the rotating shaft of the massager transmission shaft to be connected with the motor in the massager. Currently, the transmission gear is assembled by manually hammering the transmission gear with a rubber hammer to assemble the transmission gear to a specified position on the rotating shaft. However, this method not only has poor assembly efficiency, but also makes it difficult to ensure the verticality of the transmission gear and the rotating shaft. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a transmission gear assembly tool for a transmission shaft of a massager, which can quickly and effectively complete the assembly of the transmission gear on the rotating shaft.

[0018] 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.

[0019] It should be noted that the first direction referred to below is a direction parallel to the axis of the rotating shaft 5 .

[0020] Please refer to Figure 2 and Figure 3 As shown, the utility model is a transmission gear assembly tool for a transmission shaft of a massager, comprising a positioning component 1 and an assembly component 2; the positioning component 1 comprises a rotating shaft positioning seat 11 and a gear positioning seat 12; a rotating shaft positioning hole 111 is arranged on the rotating shaft positioning seat 11 along a first direction, the gear positioning seat 12 can move along the first direction, a rotating shaft avoidance hole 121 and a gear profiling groove 122 are coaxially arranged on the gear positioning seat 12 along the first direction, and the rotating shaft avoidance hole 121 is communicated with the gear profiling groove 122;

[0021] The built-in component 2 includes a reciprocating device 21 and a pressing block 22 ; the reciprocating device 21 has a movable end that moves along a first direction, and the pressing block 22 is arranged on the movable end of the reciprocating device 21 .

[0022] Working principle: During the assembly process, the rotating shaft 5 is inserted into the rotating shaft positioning hole 111 of the rotating shaft positioning seat 11 for positioning, and then the transmission gear 6 is placed in the gear profiling groove 122 for positioning. Finally, the reciprocating device 21 drives the pressing block 22 to press the transmission gear 6, so that the gear positioning seat 12 can be close to the rotating shaft positioning seat 11, so that the rotating shaft 5 passes through the rotating shaft avoidance hole 121 and is assembled with the transmission gear 6.

[0023] It is worth noting that since the rotating shaft 5 passes through the transmission gear 6, the pressing block 22 can be a cylindrical structure, so that the rotating shaft 5 can extend into the inner cavity of the pressing block 22 after passing through the assembly hole of the transmission gear 6, avoiding interference between the pressing block 22 and the rotating shaft 5.

[0024] The pressing block 22 can also be a plurality of top blocks connected to the movable end of the reciprocating device 21. Each top block and the movable end of the reciprocating device 21 enclose a clearance space for the rotating shaft 5 to extend into, so that the rotating shaft 5 can extend into the clearance space after passing through the assembly hole of the transmission gear 6, thereby avoiding interference between the pressing block 22 and the rotating shaft 5.

[0025] Please refer to Figure 2 As shown, further, a guide column 112 is provided on the rotating shaft positioning seat 11 , and the gear positioning seat 12 is slidably disposed on the guide column 112 .

[0026] It can be known from the above description that the guide column 112 can ensure the movable direction of the gear positioning seat 12, thereby ensuring the verticality of the transmission gear 6 and the rotating shaft 5 after assembly.

[0027] Please refer to Figure 2 As shown, further, a spring 3 is sleeved on the body of the guide column 112 , one end of the spring 3 abuts against the shaft positioning seat 11 , and the other end of the spring 3 abuts against the gear positioning seat 12 .

[0028] It can be seen from the above description that when the reciprocating device 21 drives the pressing block 22 away from the rotating shaft positioning seat 11, the gear positioning seat 12 can reset itself by utilizing the elastic force of the spring 3, so as to facilitate the assembly personnel to perform the operation.

[0029] Please refer to Figure 1As shown, further, the reciprocating device 21 includes a first driver 211 and a second driver 212, the first driver 211 has an active end that moves along a first direction, a pressure block 22 is provided on the active end of the first driver 211, the second driver 212 has an active end that moves along the first direction, and the active end of the second driver 212 is connected to the body of the first driver 211.

[0030] From the above description, it can be seen that during the operation of the reciprocating device 21, the second driver 212 drives the first driver 211 and the pressure block 22 to approach the positioning component 1, so as to facilitate the assembler to take and place the workpiece; the first driver 211 drives the pressure block 22 to assemble the transmission gear 6 into the rotating shaft 5.

[0031] Please refer to Figure 1 As shown, further, a pressure sensor 4 is provided between the movable end of the second driver 212 and the body of the first driver 211 .

[0032] It can be seen from the above description that the pressure sensor 4 can detect in real time the pressure applied by the assembly 2 to the transmission gear 6 to avoid overpressure.
