[0022] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0023] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.
[0024] Such as Figures 1-4As shown in the figure, a pushing mechanism for an in-machine automatic side-pushing fixture includes a fixture table 1. On the upper surface of the fixture table 1, two vertically distributed sliding grooves 2 are provided. The two sliding grooves 2 are respectively located on the side of the workpiece placement position of the fixture table 1, and a lead screw 5 and a rotating member 6 are rotatably connected in each sliding groove 2. A pushing mechanism driven by the lead screw 5 and the rotating member 6 is slidably connected in the sliding groove 2. The position of the pushing mechanism in the sliding groove 2 is adjusted by rotating the lead screw 5, and the pushing mechanism is used to push and prevent the fixture on the fixture table 1 from moving by rotating the rotating member 6. A driving cavity 4 is provided between the adjacent ends of the two sliding grooves 2 on the table surface of the fixture table 1. One end of the lead screw 5 and the rotating member 6 rotatably penetrates the fixture table 1 and extends into the driving cavity 4, and a bevel gear block 10 is fixedly installed. A moving frame 13 is slidably connected to the wall of the driving cavity 4. A motor 12 is fixedly connected to one side of the moving frame 13. The main shaft of the motor 12 extends into the moving frame 13, and two bevel gear rings 17 are fixedly installed on the shaft surface. The two bevel gear rings 17 on the main shaft of the motor 12 are rotated by driving the motor 12, and the position is adjusted by moving the moving frame 13 up, down, left and right in the driving cavity 4. A double-headed bevel gear member 16 is also rotatably connected to the moving frame 13. One end of the double-headed bevel gear member 16 meshes with one of the bevel gear rings 17, and the other end is respectively used to drive the bevel gear block 10 corresponding to the two sliding grooves 2 to rotate. Both ends of the double-headed bevel gear member 16 are provided in a bevel gear shape, and the size of the double-headed bevel gear member 16 is the same as that of the bevel gear ring 17. As Figure 3 shown in the figure, when the moving frame 13 is located at this position, when the main shaft of the motor 12 rotates, the right bevel gear ring 17 idles, while the left bevel gear ring 17 drives the engaged double-headed bevel gear member 16 to rotate. The double-headed bevel gear member 16 then drives the bevel gear block 10 on the end face of the rotating member 6 in the left sliding groove 2 to rotate. When the moving frame 13 moves backward, the bevel gear block 10 on the end face of the rotating member 6 in the right sliding groove 2 is driven by the right bevel gear ring 17 to rotate. When the moving frame 13 moves down a certain distance and then moves forward, the double-headed bevel gear member 16 drives the bevel gear block 10 on the end face of the lead screw 5 in the left sliding groove 2 to rotate. When the moving frame 13 moves backward, the bevel gear block 10 on the end face of the lead screw 5 in the right sliding groove 2 is driven by the right bevel gear ring 17 to rotate.
[0025] Furthermore: An insertion tooth ring 8 inserted on the rotating member 6 is rotatably connected in the slider 7, and a transmission gear 9 meshing with the insertion tooth ring 8 and the rack plate 3 is rotatably connected. When the slider 7 slides in the sliding groove 2, the insertion tooth ring 8 will be driven to slide on the surface of the rotating member 6, and when the rotating member 6 rotates, the insertion tooth ring 8 will be driven to rotate independently. Then, under the meshing connection of the transmission gear 9, the rack plate 3 is moved to push the fixture to move.
[0026] Further: The driving mechanism includes a slider 7 threadedly connected to the lead screw 5 and inserted into the rotating member 6. A rack plate 3 driven by the rotating member 6 is mounted on the slider 7. One end of the rack plate 3 is L-shaped and is used to push the fixture. The two lead screws 5 and the two rotating members 6 are arranged at the same height. Guide frames 11 are fixedly connected to the inner cavity walls of the driving cavity 4 facing both sides of the moving frame 13. The inside of the guide frame 11 is in an I-shape, and the four end points of the inner end of the guide frame 11 respectively correspond to one of the bevel gear blocks 10. As Figure 3 shown, both the surface of the moving frame 13 and the motor 12 extend outward and are slidably connected to the inside of the guide frame 11. Therefore, the provided guide frame 11 facilitates restricting the moving direction of the moving frame 13. Two vertically distributed electric telescopic rods 14 are fixedly connected to the inner wall of the driving cavity 4. The telescopic ends of the two electric telescopic rods 14 are respectively arranged facing the side and the bottom of the moving frame 13. A plug 15 inserted into the moving frame 13 is fixedly connected to the telescopic end of the electric telescopic rod 14. As Figure 3 and Figure 4 shown, when the lower vertical electric telescopic rod 14 expands and contracts, it drives the moving frame 13 to move up and down along the surface of the upper plug 15. When the upper horizontal electric telescopic rod 14 expands and contracts, it drives the moving frame 13 to slide horizontally along the surface of the lower plug 15, so as to adjust the position of the moving frame 13 in the driving cavity 4.
[0027] Working principle: During use, place the fixture at a general position on the fixture table 1. When it is necessary to push the fixture to move and adjust the position of the fixture, according to the moving direction, adjust the position of the moving frame 13 in the driving cavity 4, so that the double-headed bevel gear member 16 or the bevel gear ring 17 on the moving frame 13 in the driving cavity 4 drives the bevel gear block 10 at a certain upper or lower position on the corresponding side to rotate, and then the rotation of the lead screw 5 or the rotating member 6 in the sliding groove 2 in the corresponding direction can be realized. By using the rotation of the lead screw 5 to adjust the position of the slider 7 and the rack plate 3 on its surface, and using the rotation of the rotating member 6 to force the rack plate 3 to move and push the fixture to move.
[0028] The wiring diagrams of the motor 12 and the electric telescopic rod 14 in the present utility model belong to the common knowledge in the art. Their working principles are already known technologies. Their models are selected according to actual use. Therefore, the control methods and wiring arrangements of the motor 12 and the electric telescopic rod 14 will not be explained in detail.
[0029] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present utility model, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model still fall within the protection scope of the technical solution of the present utility model.
