Description

Technical Field

[0001] This utility model relates to the field of clamp processing technology, specifically a clamping component for clamp processing and forming. Background Technology

[0002] A clamp is a connecting device used to connect grooved pipe fittings, valves, and pipeline accessories. It is also used to tighten quick-connect couplings. These couplings typically have gaskets made of rubber, silicone, or PTFE. In some places, safety clips (DIN2817) are also referred to as clamps. They come in various types and are made of various materials, such as rubber, silicone, PTFE, plastic, steel, and stainless steel.

[0003] During the processing of clamps, it is necessary to maintain their stability. Generally, a corresponding positioning structure needs to be designed to fix them. Since clamps need to be adjusted to a certain extent in terms of angle or position during the processing and forming process, the positioning structure needs to have a quick and convenient adjustment capability. However, some existing positioning structures lack effective adjustment capabilities.

[0004] Therefore, in view of the above-mentioned problems, this technical solution proposes a clamping component for clamp processing and forming. Summary of the Invention

[0005] The purpose of this utility model is to provide a clamping component for processing and forming clamps, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamping component for forming a clamp, comprising a positioning base plate, the positioning base plate being configured with an L-shaped structure, a circular positioning groove being formed on one side of the positioning base plate, the clamp to be formed being placed in the positioning groove, two sets of side clamping plates and one set of bottom clamping plates being arranged in a triangular distribution on the outer side of one side of the positioning groove, the bottom clamping plate and the side clamping plates moving along the positioning groove to triangularly clamp and position the clamp placed inside the positioning groove, wherein the end of the bottom clamping plate away from the positioning groove is connected to a main telescopic component, and the two side clamping plates are away from the positioning groove. One end of the slot is connected to a telescopic assembly. Two sets of telescopic assemblies are staggered along the axis of the positioning slot on both sides of the main telescopic assembly. The side of the telescopic assembly closest to the main telescopic assembly is engaged with the main telescopic assembly. The end of the main telescopic assembly away from the positioning slot is connected to a hydraulic rod. The end of the hydraulic rod is connected to a hydraulic cylinder. The hydraulic cylinder is fixed on the positioning base plate. That is, by activating the hydraulic cylinder, the hydraulic rod is extended or retracted, thereby driving the main telescopic assembly to move, controlling the bottom clamping plate to move, and simultaneously driving the telescopic assemblies on both sides to synchronously control the side clamping plates to move, so as to quickly and stably clamp and fix the clamp.

[0007] Compared with the prior art, the beneficial effects of this utility model are: by setting a single set of hydraulic cylinders to control the extension and retraction of hydraulic rods, and then, with the cooperation of the main extension assembly and the secondary extension assembly, the two sets of side clamping plates and one set of bottom clamping plates located around the positioning groove are synchronously controlled to move synchronously, and then the clamp placed in the positioning groove is automatically clamped and fixed or released away, thereby realizing a fast and convenient fixed clamping during the clamp forming process.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] Please see Figures 1-4 A clamping component for forming a clamp includes a positioning base plate 10, which is configured with an L-shaped structure. A circular positioning groove 11 is formed on one side of the positioning base plate 10. The clamp to be formed is placed in the positioning groove 11. Two sets of side clamping plates 18 and one set of bottom clamping plates 17 are arranged in a triangular pattern on the outer side of one side of the positioning groove 11. The bottom clamping plates 17 and side clamping plates 18 move along the positioning groove 11 to triangularly clamp and position the clamp placed inside the positioning groove 11. The bottom clamping plate 17 is connected to a main telescopic assembly at its end away from the positioning groove 11, and the two side clamping plates 18 are connected to... Two sets of telescopic components are staggered along the axis of the positioning groove 11 on both sides of the main telescopic component. The side of the telescopic component closest to the main telescopic component is engaged with the main telescopic component. The end of the main telescopic component away from the positioning groove 11 is connected to a hydraulic rod 13, and the end of the hydraulic rod 13 is connected to a hydraulic cylinder 12. The hydraulic cylinder 12 is fixed on the positioning base plate 10. That is, by activating the hydraulic cylinder 12, the hydraulic rod 13 is controlled to extend and retract, thereby driving the main telescopic component to move, controlling the bottom clamping plate 17 to move, and simultaneously driving the two telescopic components on both sides to synchronously control the side clamping plates 18 to run, so as to quickly and stably clamp and fix the clamp.

[0018] In this embodiment of the invention, both the bottom clamping plate 17 and the side clamping plate 18 are configured as arc-shaped structures. A buffer layer is provided on the side of the bottom clamping plate 17 and the side clamping plate 18 that contacts the clamp, so as to ensure that the clamp is clamped and fixed without causing wear to the clamp.

[0019] The positioning base plate 10 has multiple mounting holes, which, together with bolts and other structures, fix the positioning base plate 10.

[0020] In one embodiment of the present invention, the main telescopic assembly includes a connecting rod 25 connected to one side of the back of the bottom clamping plate 17. The end of the connecting rod 25 is connected to a double-sided rack 16. The end of the bottom clamping plate 17 away from the connecting rod 25 is rotatably connected to the hydraulic rod 13. Meanwhile, toothed grooves are symmetrically opened on both sides of the double-sided rack 16. Driven gears 26 are meshed on the outside of the toothed grooves on both sides. The bottom of the driven gears 26 is rotatably connected to the positioning base plate 10 through the toothed shaft 23. While the hydraulic cylinder 12 controls the hydraulic rod 13 to drive the double-sided rack 16 to extend and retract, the toothed grooves on both sides drive the driven gears 26 to rotate. The outside of the driven gears 26 meshes with the telescopic assembly, thereby driving the telescopic assembly to run.

[0021] Specifically, a connecting block 14 is installed at the end of the hydraulic rod 13, and a U-shaped connecting block 15 is connected to the end of the double rack 16. The connecting block 14 extends into the U-shaped connecting block 15 and is swayed through the swing shaft 24. This is used to maintain the hydraulic rod 13 to provide local micro-rotation when controlling the extension and retraction of the double rack 16, so as to prevent the connection from being too stiff and affecting the movement control of the bottom clamping plate 17 and the two side clamping plates 18.

[0022] The telescopic assembly includes a single-sided rack 21 that meshes with the driven gear 26. The two sides of the single-sided rack 21 are respectively placed on the upper and lower sides of the double-sided rack 16. The end of the single-sided rack 21 away from the positioning groove 11 is connected to a limiting slide rod 20. The bottom of the limiting slide rod 20 is slidably connected to a limiting slide rail 19 fixed on the positioning base plate 10. By sliding the limiting slide rod 20 in the limiting slide rail 19, the single-sided rack 21 can be stably telescopically moved. The other end of the single-sided rack 21 is connected to the side clamping plate 18, so that the driven gear 26 drives the single-sided rack 21 to telescopically control the movement of the side clamping plate 18 and fix the clamp.

[0023] Specifically, limit slide bars 22 are symmetrically installed on both sides of the limit slide bar 20. The inner wall of the limit slide rail 19 corresponding to the limit slide bar 22 is provided with a slide groove. The limit slide bar 22 moves along the slide groove to realize the limit sliding between the limit slide bar 20 and the limit slide rail 19.

[0024] The working principle of this utility model is as follows: In the idle position of this device, all the aforementioned driving components, which refer to power elements, electrical components, and compatible power supplies, are connected by wires. The electrical components are connected in sequence to complete the electrical connection. The detailed connection method is known in the field. The following mainly introduces the working principle and process, without describing the electrical control. In use, the clamp to be processed is placed in the positioning groove 11, and then the hydraulic cylinder 12 is started to drive the hydraulic rod 13 to extend outward. At this time, the double-sided rack 16 drives the bottom clamping plate 17 to extend outward. At the same time, when the double-sided rack 16 extends and retracts, it drives the driven gears 26 on both sides to rotate and controls the single-sided rack 21 to rotate, thereby driving the driven gear 26 to move outward synchronously. This controls the side clamping plate 18 at the end to move towards the center of the positioning groove 11. Then, with the cooperation of the bottom clamping plate 17 and the side clamping plate 18, the clamp at the positioning groove 11 is fixed.

[0025] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
