The workpiece carrier front shaft 18 passes through the first bearing 16, and the first bearing 16 is disposed between the workpiece carrier front shaft 18 and the bearing retainer 17, so that the workpiece carrier front shaft 18 can rotate relative to the bearing retainer 17, i.e., the workpiece carrier front shaft 18 can rotate relative to the shaft positioning bracket 19.

The workpiece holder front shaft 18, the workpiece holder 20, and the workpiece holder rear shaft 23 are integrally formed, and rotatably mounted on the two-shaft positioning bracket 19.

In an embodiment, the watch wearing simulator further comprises a controller (not shown in the figure), and the motor 2 is electrically connected with the controller, and the controller controls the action of the watch wearing simulator.

In use, the watch can be sleeved on one workpiece frame 20, correspondingly, a plurality of watches can be sleeved on six workpiece frames 20, and wearing action simulation can be carried out on the plurality of watches simultaneously.

During the operation, on one hand, when the motor 2 rotates, the first chain wheel 3 and the chain 5 can drive the second chain wheel 54 to rotate, and then the second chain wheel 54 drives the first transmission shaft 6, the second transmission shaft 12 and the third transmission shaft 33 to rotate. When the second transmission shaft 12 and the third transmission shaft 33 rotate, the rear hexagonal joint 13, the lower connecting rod 14, the upper connecting rod 21, the workpiece holder 20 and the front hexagonal joint 29 are driven to synchronously rotate. Because the reciprocating screw rod 27 is fixedly installed relative to the frame 1, under the threaded fit of the reciprocating screw rod nut 28 and the reciprocating screw rod 27, when the front hexagonal connector 29 drives the reciprocating screw rod nut 28 to rotate, the reciprocating screw rod nut 28 can be driven to reciprocate along the axial direction of the reciprocating screw rod 27, and further the upper connecting rod 21 and the lower connecting rod 14 can be unfolded or folded, so that the simulation of the swing action of the arm is realized.

On the other hand, the first transmission shaft 6 drives the rotating disc 42 to rotate synchronously, and accordingly, the rotating disc 42 drives the second gear 45 to rotate around the axis of the first transmission shaft 6. The second gear 45 is engaged with the inside of the first gear 9, and the first gear 9 is fixedly mounted with respect to the frame 1. When the second gear 45 rotates around the first transmission shaft 6, the second gear 45 rotates around its own axis under the driving of the first gear 9, and then drives the fourth transmission shaft 43 to rotate. When the fourth transmission shaft 43 rotates, the third universal coupling 38, the second flexible shaft 37, the second universal coupling 36, the first flexible shaft 35 and the first universal coupling 34 are sequentially driven to rotate correspondingly. Further, the first universal coupling 34 drives the workpiece holder front shaft 18 and the workpiece holder 20 to rotate around the shafts. Therefore, the simulation of the arm rotation action is realized.

When the swinging action and the rotating action are carried out simultaneously, the composition of the two actions can be realized, and therefore the complex action that the watch is worn by the hand can be realized. Meanwhile, the controller can control the motor 2 to perform actions such as sudden stop, speed change, positive and negative rotation and the like. Therefore, the action of the watch simulating wearing machine is closer to the actual hand wearing condition, and further, in the subsequent test process of the watch, the measured data is closer to the actual wearing condition, so that the measured data is more reliable and has more reference value.
