Technical Field
[0001] The utility model relates to the technical field of quick positioning and clamping devices, in particular to a quick positioning and clamping device. Background Technique
[0002] A thin-walled part refers to a component made of metal or non-metal materials with a relatively thin wall thickness. These components are widely used in the fields of aviation, aerospace, automotive, electronics, etc. Due to the thin wall thickness of the thin-walled parts, they are easily affected by various factors during the manufacturing process, such as deformation, cracks, etc. Therefore, the manufacturing process and quality control requirements of thin-walled parts are relatively high.
[0003] When batch processing existing thin-walled parts, a special inner support type processing tooling is required for auxiliary processing, so that the blank pipe can be processed into a finished thin-walled part. Due to the single function of the existing thin-walled part processing tooling, it can only be used for the processing of thin-walled parts with a specific pipe diameter and cannot meet the processing requirements of more types of thin-walled parts. If different processing toolings are produced, the usage cost is relatively high. Therefore, we provide a quick positioning and clamping device for batch production of thin-walled parts. Content of the Utility Model
[0004] The purpose of the utility model is to solve the shortcoming of the single function of the existing thin-walled part processing tooling in the prior art, and provide a quick positioning and clamping device.
[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: A quick positioning and clamping device, comprising: a main body mechanism, the main body mechanism includes a convex block, an extrusion mechanism is arranged inside the convex block, the extrusion mechanism includes a threaded rod, the threaded rod penetrates through the inside of the convex block, the threaded rod is threadedly connected with the convex block, a threaded groove matching the threaded rod is opened inside the convex block, a conical block is sleeved on the outer surface of the threaded rod, the conical block is fixedly connected with the threaded rod, a moving block is sleeved inside the convex block, the number of the moving blocks is four, the moving blocks are slidably connected with the convex block, an arc groove matching the conical block is opened on the moving block, a T-shaped block is fixedly connected to one side surface of the moving block, the T-shaped block penetrates through the inside of the convex block, the T-shaped block is slidably connected with the convex block, and a T-shaped groove matching the T-shaped block is opened on the convex block.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0026] In this embodiment, by providing the extrusion mechanism 2, the blank tube for thin-walled part processing can be internally supported and fixed, so that the blank tube can remain stable during processing, and at the same time, the finished thin-walled part will not be damaged. By providing the threaded rod 21, the conical block 23 can be driven to rotate and move through the threaded connection with the convex block 11. Then, during the rotation and movement of the conical block 23, the moving block 24 can be extruded, so that the outer circumferential surface of the moving block 24 can be closely attached to and fixed to the inner wall of the blank tube. In addition, by providing the T-shaped block 25 and opening the T-shaped groove 26 on the convex block 11, the sliding of the moving block 24 will not deviate, so that the support and fixation of the inner wall of the thin-walled part are uniform. At the same time, by providing the positioning plate 12, the blank tube can be blocked, making the blank tube more stable during processing.
[0027] Embodiment 2
[0028] As Figures 1 - 5 shown, an auxiliary mechanism 3 is provided inside the convex block 11. The auxiliary mechanism 3 includes a sleeve rod 31. The sleeve rod 31 penetrates through the inside of the convex block 11. The sleeve rod 31 is slidably connected to the convex block 11. One end of the sleeve rod 31 is fixedly connected with a limit piece 32. A spring 33 is sleeved on the outer surface of the sleeve rod 31. One end of the spring 33 is fixedly connected to the outer surface of the limit piece 32. The other end of the spring 33 is fixedly connected to the inner wall of the convex block 11. The end of the sleeve rod 31 away from the limit piece 32 is fixedly connected with a connection block 34. The connection block 34 is fixedly connected with the moving block 24.
[0029] In this embodiment, by providing the auxiliary mechanism 3, the moving block 24 can always be in a fitting state with the conical block 23, and the four moving blocks 24 can slide into the convex block 11 simultaneously, so that the finished thin-walled part can be removed smoothly. By providing the spring 33, using the characteristic that the spring 33 can generate elastic force when being extruded, the sleeve rod 31 and the limit piece 32 can be reset, so as to indirectly achieve the purpose of driving the moving blocks 24 to slide synchronously.
[0030] Working principle:
[0031] As Figures 1 - 5As shown in the figure, when the utility model is in use, first fix one end of the convex block 11 close to the positioning plate 12 by means of a chuck, and then sleeved the blank pipe of the thin-walled part to be processed on the outside of the convex block 11 and make it fit with the positioning plate 12. At this time, rotate the knob 27, and drive the threaded rod 21 to rotate by means of the knob 27. Since a threaded groove 22 matching the threaded rod 21 is opened inside the convex block 11, the threaded rod 21 can rotate and move, and thus can drive the tapered block 23 to rotate and move synchronously. Since each part of the tapered block 23 is uniform, and an arc groove matching the tapered block 23 is opened on the moving block 24, when the tapered block 23 rotates and moves, it will squeeze the four moving blocks 24 and slide them to the outside of the convex block 11. At the same time, the moving block 24 will drive the T-shaped block 25 to slide in the T-shaped groove 26 opened on the convex block 11 until the moving block 24 is in close contact with the inner wall of the blank pipe and the blank pipe is in a stable state. While the moving block 24 slides, the moving block 24 will drive the sleeve rod 31 by means of the connecting block 34, so that the sleeve rod 31 and the limiting piece 32 slide in the convex block 11 and compress the spring 33, so that the spring 33 generates elastic force. At this time, the blank pipe can be processed to make the blank pipe into a thin-walled part with a qualified thickness. If it is necessary to remove the finished thin-walled part, the knob 27 can be rotated in the reverse direction, so that the threaded rod 21 drives the tapered block 23 to rotate and move in the reverse direction. Then, the extrusion of the tapered block 23 on the moving block 24 is gradually released, and the elastic force generated by the spring 33 will reset the sleeve rod 31 and the limiting piece 32, and at the same time drive the moving block 24 to reset, so that the moving block 24 is separated from the inner wall of the thin-walled part, and then the thin-walled part can be removed.
[0032] The above is only the preferred embodiment of the present utility model, and it is not a limitation to the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above 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 according to the technical essence of the present utility model still belong to the protection scope of the technical solution of the present utility model.
