[0017] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0018] like Figures 1 to 6 As shown, a flexible motor for a bolt machine includes a motor 1 and a motor base 2. The motor 1 is mounted on the motor base 2. A bolt sleeve 3 is mounted on the output end of the motor 1. A hexagonal hole 4 is formed at the bottom end of the bolt sleeve 3. An exhaust hole 5 communicating with the hexagonal hole 4 is formed on the bolt sleeve 3. The existence of the exhaust hole 5 facilitates the bolt to smoothly enter the hexagonal hole 4 of the bolt sleeve 3.

[0019] Two groups of flexible mechanisms are symmetrically installed on the motor base 2, and each group of flexible mechanisms includes two flexible components 6. The flexible component 6 includes an upper joint shaft 6-1, an upper connecting block 6-2, a telescopic square rod 6-3, a limit pin 6-4, a spring 6-5, a square rod sleeve 6-6, a lower connecting block 6-7 and a lower joint shaft 6-8. The lower joint shaft 6-8 is fixed on the motor base 2, and a pair of ears is provided on the top of the lower joint shaft 6-8. The lower connecting block 6-7 is installed between the pair of ears. The lower connecting block 6-7 is rotatably connected to the ears. A pair of ears is provided at the bottom end of the square rod sleeve 6-6. The lower connecting block 6-7 is rotatably connected to the ears. Dynamic connection, a hexagonal blind hole 6-9 is provided at the top of the square rod sleeve 6-6, the bottom end of the telescopic square rod 6-3 is movably fitted in the hexagonal blind hole 6-9, and a spring 6-5 is installed between the bottom of the hexagonal blind hole 6-9 and the telescopic square rod 6-3, a long hole 6-10 is provided on the telescopic square rod 6-3 along the length direction, the limit pin 6-4 passes through the long hole 6-10, and its two ends are connected with the square rod sleeve 6-6, a pair of ears is provided at the top of the telescopic square rod 6-3, the upper connecting block 6-2 is rotatably connected to the pair of ears, and a pair of ears is provided at the bottom end of the upper joint shaft 6-1, and the upper connecting block 6-2 is rotatably connected to the ears.

[0020] The shape of the telescopic square rod 6-3 matches the inner hexagonal blind hole 6-9. The bottom end of the telescopic square rod 6-3 is provided with an extension shaft 6-11, and the spring 6-5 is sleeved on the extension shaft 6-11. The bottom end of the spring 6-5 contacts the bottom of the inner hexagonal blind hole 6-9, and the top end contacts the bottom end of the telescopic square rod 6-3.

[0021] In this embodiment, the two flexible components of the flexible mechanism are connected by a limiting mechanism, which includes a left connecting block 7, a right connecting block 8, an upper connecting plate 9 and a lower connecting plate 10. One side of the left connecting block 7 is connected to the square rod sleeve 6-6, and the two ends of the other side extend outward with protrusions 11. One side of the right connecting block 8 is connected to the square rod sleeve 6-6, and the two ends of the other side extend outward with protrusions 11. The two ends of the upper connecting plate 9 and the lower connecting plate 10 are respectively hinged to the protrusions 11.

[0022] In this embodiment, the outer wall of the square rod sleeve 6 - 6 is provided with a mounting groove 12 , and the left and right connecting blocks 7 , 8 are both interference fit with the mounting groove 12 .

[0023] During operation, the upper joint shaft 6-1 is fixed on the rail bolt machine. After the bolt sleeve 3 is aligned with the bolt, the bolt machine drives the flexible motor to move downward so that the bolt is inserted into the hexagonal hole 4 of the bolt sleeve 3. Since the flexible motor has a certain degree of freedom, even if the position of the bolt sleeve 3 and the bolt is slightly deviated, the bolt can smoothly enter the hexagonal hole 4 of the bolt sleeve 3.

[0024] In the utility model, due to the connection structure between the upper joint shaft 6-1 and the telescopic square rod 6-3, and the connection structure between the lower joint shaft 6-8 and the square rod sleeve 6-6, the motor 1 has a certain degree of freedom in all directions during the alignment process. The cooperation between the telescopic square rod 6-3 and the square rod sleeve 6-6 prevents the motor 1 from rotating. The spring 6-5 can play a certain protective role on the overall equipment. The limiting mechanism can ensure that after the bolt sleeve 3 is inserted into the bolt, the motor 1 will not rotate during the operation, and has a certain structural strength.

[0025] Compared with the prior art, the utility model allows the motor to have a certain degree of freedom, and at the same time has sufficient structural strength to support the work during the working process and will not move arbitrarily, thereby improving the insertion rate during the bolt insertion process.
