Detailed implementation

[0020] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying 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.

[0021] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0022] Embodiment 1, as Figures 1 - 4 shown, the present invention provides a positioning tooling for a five-axis machining center, including: a support plate 1, a processing table 2 is fixedly connected to the top of the support plate 1, and a plurality of notches 3 are evenly opened on the top of the processing table 2; a positioning component 4, the number of the positioning components 4 is set to be multiple, and the multiple positioning components 4 are respectively fixedly connected to the inner surfaces of the multiple notches 3. The positioning component 4 includes a spring 401 and two limit rods 402. A sliding seat 403 is fixedly connected to the end face of the spring 401. A moving plate 404 is fixedly connected to the top of the sliding seat 403. Side plates 405 are symmetrically fixedly connected to the top of the moving plate 404. A first hydraulic rod 406 is fixedly connected to the outer surface of the side plate 405. The output end of the first hydraulic rod 406 penetrates through the side plate 405 and extends to the other side. A clamping plate 407 is fixedly connected to the output end of the first hydraulic rod 406. A motor 5 is fixedly connected to the bottom of the support plate 1. The output end of the motor 5 penetrates through the support plate 1 and extends to the upper side. A rotating shaft 6 is fixedly connected to the output end of the motor 5. A first gear 7 is fixedly connected to the upper end face of the rotating shaft 6. A plain bearing 12 is fixedly connected to the top of the support plate 1. The plain bearing 12 is located outside the processing table 2. A second gear 8 is fixedly connected to the top of the plain bearing 12. The second gear 8 is meshed with the first gear 7. A support 9 is fixedly connected to the top of the second gear 8. A second hydraulic rod 10 is fixedly connected to the outer surface of the support 9. The output end of the second hydraulic rod 10 penetrates through the support 9 and extends to the other side. A pushing plate 11 is fixedly connected to the output end of the second hydraulic rod 10. The pushing plate 11 is matched with the position of the sliding seat 403.

[0023] The effect achieved by the entire Embodiment 1 is that when using a five-axis machining center to machine a workpiece, the workpiece is clamped and fixed by using a positioning tooling. Through the arrangement of installing a plurality of positioning components 4 in the plurality of notches 3 respectively, the plurality of workpieces can be clamped and fixed at the positions of the respective positioning components 4. When clamping, the workpiece is placed above the moving plate 404, and then the first hydraulic rod 406 is started to extend. The first hydraulic rod 406 can drive the clamping plate 407 to move towards the workpiece, thereby clamping and fixing the workpiece. After the workpiece is clamped and fixed at the positions of the respective moving plates 404, the second hydraulic rod 10 is started to operate. After the second hydraulic rod 10 operates, it can drive the push plate 11 to move towards the sliding seat 403. At this time, the sliding seat 403 can drive the moving plate 404 to move towards the center position of the machining table 2. When the sliding seat 403 displaces, it will compress the spring 401 to contract. Through the position of the moving plate 404, the workpiece can be sent to the machining position at the center of the machining table 2. After the machining of the workpiece is completed by the operation of the five-axis machining center, the second hydraulic rod 10 is started to contract and reset. After the push plate 11 is reset, the resilience of the spring 401 can drive the sliding seat 403 to reset to the edge position of the machining table 2. Then the motor 5 is started. After the motor 5 is started, it can drive the first gear 7 to rotate following the connection of the rotating shaft 6. The first gear 7 can drive the support 9 to rotate through the meshing with the second gear 8. At this time, through the rotation of the support 9, it can be rotated and adjusted to the position of other sliding seats 403. After the position adjustment of the support 9 is completed, the second hydraulic rod 10 is continued to be started to push the next workpiece to the machining position to complete the machining. For the machining center, continuous feeding and machining of the workpiece can be realized, saving the time consumed for disassembling and assembling the workpiece, and effectively improving the machining efficiency.

[0024] Embodiment 2 is as Figures 1 - 4 shown, the limiting rod 402 is slidably connected through the sliding seat 403, and the moving plate 404 is located above the machining table 2.

[0025] The effect achieved by the entire Embodiment 2 is that when the sliding seat 403 is pushed to move by the operation of the second hydraulic rod 10, the arrangement of the limiting rod 402 can play a role in supporting and limiting the displacement of the sliding seat 403, thereby improving the stability of the displacement state of the workpiece.

[0026] Working principle: When machining a workpiece using a five-axis machining center, place the workpiece above the moving plate 404 during clamping. Then, start the first hydraulic rod 406 to extend. The first hydraulic rod 406 can drive the clamping plate 407 to move towards the workpiece, thereby clamping and fixing the workpiece. After the workpiece is clamped and fixed at each moving plate 404 position, start the second hydraulic rod 10 to operate. After the second hydraulic rod 10 operates, it can drive the push plate 11 to move towards the sliding seat 403. At this time, the sliding seat 403 can drive the moving plate 404 to move towards the center position of the machining table 2. When the sliding seat 403 displaces, it will compress the spring 401 to contract. The workpiece can be sent to the machining position at the center of the machining table 2 through the position of the moving plate 404. After the machining of the workpiece is completed, start the second hydraulic rod 10 to contract and reset. After the push plate 11 resets, the resilience of the spring 401 can drive the sliding seat 403 to reset to the edge position of the machining table 2. Then, start the motor 5 to operate. After the motor 5 starts, it can drive the support 9 to rotate. Through the rotation of the support 9, it can be rotated and adjusted to the position of other sliding seats 403. After the position adjustment of the support 9 is completed, continue to start the second hydraulic rod 10 to push the next workpiece to the machining position to complete the machining. For the machining center, continuous feeding and machining of workpieces can be realized, saving the time consumed for disassembling and assembling workpieces and effectively improving the machining efficiency. When the second hydraulic rod 10 operates to push the sliding seat 403 to move, the setting of the limiting rod 402 can play a role in supporting and limiting the displacement of the sliding seat 403, thereby improving the stability of the workpiece displacement state.

[0027] The above is only a preferred embodiment of the present invention, and it does not limit the present invention 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 invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
