Description

Technical Field

[0001] The utility model relates to the technical field of aerospace, and particularly relates to a positioning tooling. Background Art

[0002] Aerospace is a highly comprehensive modern technology, involving a variety of disciplines. It includes two major branches: aviation and spaceflight. Aviation refers to the navigation activities of aircraft within the Earth's atmosphere. Spaceflight refers to the navigation activities of aircraft in the outer space beyond the Earth's atmosphere, such as orbit-controlled rockets. The development of the aerospace industry has witnessed a technological leap forward and a rapid progress in social production. The achievements of aerospace have concentrated many new achievements in science and technology.

[0003] For example, a positioning tooling for aerospace machining disclosed in Chinese Patent Publication No. (CN221211438U) records: "It includes a limit plate. The bottom end of the limit plate is fixedly connected with a base, and a pushing mechanism is movably installed on the inner and outer walls of the limit plate. On both sides of the inner side wall of the limit plate, sliding rods are fixedly installed, and a sleeve is slidably sleeved at the center of the sliding rods. The upper surface of the sleeve is fixedly connected with a support platform, and baffles are fixedly connected to both sides of the outer wall of the support platform. Through the settings of the driving motor, limit ring, coupling, screw rod and rotating shaft, the driving motor and the coupling cooperate to drive the screw rod to rotate. When the screw rod rotates, it drives the support platform to slide on the outer wall of the sliding rod. The rotating shaft facilitates the rotation of the other end of the screw rod. When the positioning is completed, it is convenient to adjust the position and angle of the parts, avoiding disassembling and repositioning the aerospace parts again, saving time and effort, and improving work efficiency."

If the above device is used to fix them, it is difficult to ensure their stability. At the same time, during the machining of columnar workpieces, it is generally dynamic machining by rotation, and the angle adjustment of the workpiece after being fixed by this device is rather cumbersome. Therefore, it is necessary to propose a positioning tooling to provide a new technical solution to solve the technical problems mentioned in the above patent. Summary of the Utility Model

[0028] As described in the background art, large columnar workpieces often appear in the processing of aerospace workpieces. If the above device is used to fix them, it is difficult to ensure their stability. At the same time, the columnar workpieces are generally processed in a rotating dynamic state during processing, and the angle adjustment of the workpieces after being fixed by the device is rather cumbersome.

[0029] To solve this technical problem, the present utility model provides a positioning tooling, which is applied to the positioning and locking of columnar workpieces for aerospace use.

A positioning and processing mechanism 2 is arranged at the upper end of the main body carrier 1, and a locking mechanism 3 is arranged in the middle of the positioning and processing mechanism 2.

[0031] For the positioning tooling provided by the present utility model, by setting the positioning and processing mechanism 2, after the workpiece is placed on the upper end of the bottom Y-shaped support frame 6 and contacts the first rubber roller 7, the electric telescopic pump 9 is used to push the second rubber roller 14 to descend and cooperate with the first rubber roller 7 to squeeze the workpiece, so as to realize the rapid fixation of the workpiece. At the same time, the workpiece can freely rotate in the middle of the first rubber roller 7 and the second rubber roller 14 for dynamic processing.

[0032] To enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0033] Embodiment 1:

[0034] Please refer to Figures 2 - 5 , a positioning tooling, the positioning and machining mechanism 2 includes a servo motor 4, a bidirectional threaded rod 5, a bottom bearing assembly, a pressing assembly and a pressure regulating assembly. A servo motor 4 is fixedly connected to the top surface of the main bearing frame 1, and the transmission end of the servo motor 4 is rotatably connected to a bidirectional threaded rod 5.

[0035] Specifically, the bottom bearing assembly includes a bottom Y-shaped support frame 6 and a first rubber roller 7. The bottom Y-shaped support frame 6 is slidably connected to the top surface of the main bearing frame 1. The bottom Y-shaped support frame 6 is symmetrically arranged on the top surface of the main bearing frame 1. The bottom Y-shaped support frame 6 is threadedly connected to the bidirectional threaded rod 5. The top ends of the bottom Y-shaped support frame 6 are symmetrically and rotatably connected to a first rubber roller 7.

[0036] Specifically, the pressing assembly includes a bearing frame 8, an electric telescopic pump 9 and a cross plate 10. The bearing frame 8 is fixedly connected to the top surface of the main bearing frame 1. The electric telescopic pump 9 is fixedly connected to the top surface of the bearing frame 8. The output end of the electric telescopic pump 9 extends to the middle of the bearing frame 8. The transmission end of the bearing frame 8 is fixedly connected to a cross plate 10.

[0037] Specifically, the pressure regulating assembly includes a guiding optical rod 11, a limiting block 12, a top Y-shaped support frame 13, a second rubber roller 14 and a pressure spring 15. The guiding optical rod 11 is symmetrically and slidably connected to the middle of the cross plate 10. The top end of the guiding optical rod 11 is fixedly connected to a limiting block 12. The end of the guiding optical rod 11 away from the limiting block 12 is fixedly connected to a top Y-shaped support frame 13. The bottom ends of the top Y-shaped support frame 13 are symmetrically and rotatably connected to a second rubber roller 14. A pressure spring 15 is sleeved on the surface of the guiding optical rod 11. The two ends of the pressure spring 15 are fixedly connected to the cross plate 10 and the top Y-shaped support frame 13.

[0038] Through the above structural design, when the device is in use, the servo motor 4 is first turned on. The servo motor 4 drives the bidirectional threaded rod 5 to rotate. The rotation of the bidirectional threaded rod 5 causes the two bottom Y-shaped support frames 6 to slide on the surface of the main body carrier 1 and adjust the distance between them. After the adjustment is completed, the servo motor 4 is turned off and the columnar workpiece is placed on the upper end of the first rubber roller 7. After that, the electric telescopic pump 9 is turned on. The output end of the electric telescopic pump 9 extends to push the cross plate 10 downward. The cross plate 10 drives the second rubber roller 14 to descend and contact the surface of the columnar workpiece. After the second rubber roller 14 contacts the workpiece, the workpiece can be fixed by continuously pressing down through the cross plate 10. After that, while the columnar workpiece is fixed, it can rotate in the middle of the second rubber roller 14 and the first rubber roller 7, and thus the dynamic processing of the workpiece can be realized.

[0039] Embodiment 2:

[0040] The positioning tooling provided in Embodiment 1 is further optimized. Specifically, as Figures 5 - 6 shown, the locking mechanism 3 includes a sliding guide frame 16, a chute 17, and an extrusion locking component. The bottom surface of the cross plate 10 is fixedly connected to the sliding guide frame 16, and a chute 17 is formed through the surface of the sliding guide frame 16.

[0041] Specifically, the extrusion locking component includes a transverse guide rod 18, a clamping block 19, and a return spring 20. The middle of the sliding guide frame 16 is fixedly connected to the transverse guide rod 18. The surface of the transverse guide rod 18 is symmetrically slidably connected to the clamping block 19. The two sides of the clamping block 19 are slidably connected to the inner wall of the chute 17. Two return springs 20 are sleeved on the surface of the transverse guide rod 18.

[0042] Through the above structural design, when the workpiece needs to be completely locked, the output end of the electric telescopic pump 9 is controlled to continuously extend. The output end of the electric telescopic pump 9 extends to compress the pressure spring 15. At the same time, the bottom surface of the clamping block 19 contacts the surface of the workpiece. Under the continuous push of the electric telescopic pump 9, the two clamping blocks 19 slide in the opposite direction to open the middle part. When the clamping block 19 slides, it squeezes the return spring 20 to make it contract until the bottom surface of the sliding guide frame 16 and the two clamping blocks 19 squeeze the workpiece, and then the locking of the workpiece can be completed.
