[0015] The following further details the specific embodiments of the present utility model. It should be understood that the description of the embodiments of the present utility model herein does not limit the protection scope of the present utility model.

[0016] As Figure 1As shown in the figure, it is a schematic structural diagram of the rotation and translation mechanism provided by the present utility model. The rotation and translation mechanism includes a frame base 10, a rotation assembly 20 disposed on the frame base 10, a translation assembly 30 disposed on one side of the rotation assembly 20, a fixed platform 40 disposed on the rotation assembly 20, and a moving platform 50 disposed on the translation assembly 30. It can be imagined that the rotation and translation mechanism further includes some other functional modules, such as a power module, a screw module, etc., which are well-known technologies to those skilled in the art and will not be elaborated herein one by one.

[0017] It should be noted that the rotation and translation mechanism is used to rotate two workpieces placed on the fixed platform 40 and the moving platform 50 by 180 degrees respectively, and control the distance between them, so that the distance and position between the two workpieces conform to the state of the equipment for the next process.

[0018] The frame base 10 is used to carry each component, so that they can complete various cooperations, thereby performing rotation and translation operations on the fixed platform 40 and the moving platform 50.

[0019] Please refer to Figure 2 and Figure 3 The rotation assembly 20 includes a driving cylinder 21, a rack 22 disposed at the output end of the driving cylinder 21, a transmission gear 23 disposed on one side of the rack 22, at least four meshing gears 24 arranged on one side of the transmission gear 23, and a first tension spring 25 disposed on one side of the driving cylinder 21.

[0020] The rack 22 and the transmission gear 23 are meshed with each other, so that the driving cylinder 21 drives the rack 22 to move and can drive the transmission gear 23 to rotate.

[0021] The center of the transmission gear 23 and the center of one of the meshing gears 24 in the middle section are located on the same vertical line, and the transmission gear 23 is fixedly disposed on the meshing gear 24. The four arranged meshing gears 24 are meshed with each other, so that the rotation of the transmission gear 23 can drive the four meshing gears 24 to rotate.

[0022] The fixed platform 40 is fixedly arranged on the meshing gear 24 at the head end, and the moving platform 50 is located on the meshing gear 24 at the tail end. Thus, when the driving cylinder 21 drives the rack 22 to move a certain distance, the transmission gear 23 rotates 180 degrees, and the four mutually meshing meshing gears 24 rotate 180 degrees together, so that the fixed platform 40 and the moving platform 50 rotate 180 degrees respectively, thereby completing the adjustment of the placement postures of the products placed on the two platforms. The specific connection method between the moving platform 50 and the meshing gear 24 at the tail end will be described below.

[0023] The length direction of the first tension spring 25 is parallel to the output direction of the driving cylinder 21. A first fixing block 26 is fixedly arranged on the frame base 10 at the position of the first tension spring 25. One end of the first tension spring 25 is fixedly connected to the first fixing block 26, and the other end is fixedly connected to the rack 22. Thus, after the rack 22 moves, the first tension spring 25 is stretched and stores elastic potential energy. When performing the reset operation on the rotation of the fixed platform 40 and the moving platform 50, only need to release the pressure inside the driving cylinder 21. The driving cylinder 21 stops working, and the elastic potential energy of the first tension spring 25 is released, which can pull the rack 22 to reset, so that the four meshing gears 24 rotate 180 degrees in the reverse direction, and then the fixed platform 40 and the moving platform 50 complete the reset operation.

[0024] The translation assembly 30 includes a translation cylinder 31, a push rod 32 arranged at the output end of the translation cylinder 31, a support platform 33 arranged on one side of the moving platform 50, at least two slide rails 34 arranged on the support platform 33, and a second tension spring 35 arranged in the middle of the two slide rails 34.

[0025] The output direction of the translation cylinder 31 is parallel to the output direction of the driving cylinder 21. The translation cylinder 31 can drive the push rod 32 to make a reciprocating movement towards the moving platform 50. An L-shaped push rod 36 is arranged on the push rod 32, and a stop block 51 is arranged at the position corresponding to the L-shaped push rod 36 after the moving platform 50 rotates 180 degrees. The length direction of the slide rail 34 is parallel to the output direction of the translation cylinder 31. A slider fixedly connected to the moving platform 50 is arranged on the slide rail 34. Thus, after the moving platform 50 rotates 180 degrees, the translation cylinder 31 can drive the push rod 32 and drive the L-shaped push rod 36 to move, so as to push the stop block 51, make the moving platform 50 move on the slide rail 34, and then complete the translation operation of the moving platform 50, and control the distance between the fixed platform 40 and the moving platform 50.

[0026] The support platform 33 is fixedly connected to one of the four meshing gears 24 that is far from the fixed platform 40. In this way, the support platform 33 can rotate together with the meshing gear 24, thereby completing the rotation operation of the moving platform 50.

[0027] A second fixing block 37 is arranged on the support platform 33 near the second tension spring 35. A third fixing block 38 is provided on the side of the moving platform 50 facing the support platform 33 and corresponding to the position of the second fixing block 37. The length direction of the second tension spring 35 is parallel to the length direction of the slide rail 34. One end of the second tension spring 35 is connected to the second fixing block 37, and the other end is connected to the third fixing block 38. In this way, after the moving platform 50 completes the translation operation on the slide rail 34, the second tension spring 35 is stretched and stores elastic potential energy. When performing the reset operation, only need to release the pressure inside the translation cylinder 31, the translation cylinder 31 stops working, and the elastic potential energy of the second tension spring 35 is released, then the moving platform 50 can be pulled back to the initial position.

[0028] In another embodiment, the rotation and translation mechanism can increase the adjustment stations of the workpiece by increasing the number of the meshing gears 24 and the moving platform 50. The mechanism can also change the relative angle and distance between the mechanism and the workpiece by changing the output distance of the driving cylinder 21 and the translation cylinder 31.

[0029] Compared with the prior art, the rotation and translation mechanism provided by the present utility model drives the rack 22 to move through the driving cylinder 21, so that the meshing gear 24 rotates, thereby driving the fixed platform 40 and the moving platform 50 to rotate. The translation cylinder 31 drives the push rod 32 to move, thereby pushing the moving platform 50 to move. The whole mechanism can independently complete the adjustment of the relative angle and distance between two workpieces, so as to adapt to the next production process. The mechanism does not require manual participation throughout the process, has a high degree of automation, and is suitable for assembly line production.

[0030] The above is only the preferred embodiment of the present utility model, and is not used to limit the protection scope of the present utility model. Any modification, equivalent replacement or improvement within the spirit of the present utility model is covered within the scope of the claims of the present utility model.
