Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen spring processing, in particular to a positioning tool for nitrogen spring processing. Background Art

[0002] Nitrogen spring is a new type of elastic component that uses high-pressure nitrogen as the working medium. It can perform tasks that are difficult for conventional elastic components such as metal springs, rubber and air cushions to accomplish, simplifying mold design and manufacturing. It is a new generation of the most ideal elastic component with flexible performance. During the processing of nitrogen springs, positioning and clamping equipment is required to position them multiple times to avoid damage caused by shaking during subsequent processing.

[0003] The utility model patent with the existing authorization announcement number CN216759633U discloses a positioning tool for nitrogen spring processing, including a workbench and a double positioning mechanism, a side baffle is fixedly installed on the left side of the top of the workbench, and the double positioning mechanism for bidirectional vertical positioning of the nitrogen spring is installed on the right side of the top of the workbench, and the double positioning mechanism includes a vertical plate, a rotating rod, a cam, a top pressure plate, a handle, a slide, a screw and a compression spring. To solve the technical problem that the existing equipment is difficult to position and clamp during the processing of the nitrogen spring due to the structural characteristics of the nitrogen spring itself, and the nitrogen spring is easily damaged during the production process due to unstable positioning and clamping, a positioning tool for nitrogen spring processing is provided, and a clamping device with multiple positioning functions is specially designed according to the structural characteristics of the nitrogen spring itself. While synchronously positioning and clamping the top and side end faces vertically, the output rod of the nitrogen spring is supported by a flexible material support plate, which completes the horizontal positioning while also playing a role of protection and damage prevention.

[0004] After analysis, it was found that although this patent can effectively clamp and position nitrogen springs and can clamp nitrogen springs of different sizes at the same time, it can only complete the clamping and positioning of one group of nitrogen springs at a time, and the work efficiency is low.

[0025] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, as Figures 1-6 shown, a positioning tooling for nitrogen spring processing includes a base 1 and a driving device arranged on the surface of the base 1. The driving device includes a cylinder 2 and a push rod 201. The cylinder 2 is fixedly connected to the base 1, and the output end of the cylinder 2 is connected with the push rod 201. Starting the cylinder 2 can push the push rod 201 to move. A sliding table 3 is fixedly connected to the surface of the base 1, a guide post is arranged on the upper surface of the sliding table 3, a partition 5 is fixedly connected to one end of the base 1 away from the sliding table 3, a moving positioning device is slidably connected to the upper end of the sliding table 3, a fixed positioning device is arranged at one end of the base 1 close to the partition 5, and the driving device drives the moving positioning device to operate.

[0027] As Figures 1-4As shown in the figure, the mobile positioning device includes a push plate 4, a sleeve 401, a first spring 402, a slide bar 403, a positioning rod 404 and a second spring 405. The surfaces of the first spring 402 and the second spring 405 are sprayed with a galvanized layer. The push plate 4 is slidably connected to the slide table 3 and connected to the push rod 201. When the push rod 201 moves, it will drive the push plate 4 to move. A guide groove is provided at the lower end of the push plate 4. A sleeve 401 is connected to the side of the push plate 4 away from the push rod 201. A first spring 402 is provided inside the sleeve 401. The sleeve 401 is slidably connected to a slide bar 403. A positioning rod 404 is connected to the side of the slide bar 403 away from the sleeve 401. A second spring 405 is provided at one end of the positioning rod 404 close to the sleeve 401. The movement of the push plate 4 drives the sleeve 401 to move, thereby pushing the slide bar 403 and the positioning rod 404 to move until the nitrogen spring is clamped. When there are nitrogen springs with different pipe diameters in multiple groups, the positioning rod 404 that first contacts the nitrogen spring stops moving. And because the slide bar 403 is slidably connected inside the sleeve 401, the push plate 4 can continue to move. The push plate 4 continues to drive the remaining sleeves 401 to move forward until all the nitrogen springs are clamped in sequence. The fixed positioning device includes a mounting table 6 and a positioning plate 601. The mounting table 6 is fixedly connected to the base 1. The mounting table 6 is connected to the positioning plate 601. The mounting table 6 and the positioning plate 601 are detachably connected by bolts, which is convenient for replacing the positioning plate 601.

[0028] The above-mentioned embodiment discloses a positioning tooling for nitrogen spring processing. Among them, when processing the nitrogen spring, multiple groups of nitrogen springs are sequentially placed on the positioning plate 601. The cylinder 2 is started to make the cylinder 2 push the push rod 201 to move, driving the push plate 4 to move. The push plate 4 drives multiple groups of sleeves to move forward, so that the slide bar 403 and the positioning rod 404 move forward until the nitrogen spring is clamped. When there are nitrogen springs with different pipe diameters, the positioning rod 404 that first contacts the nitrogen spring stops moving. At the same time, because the slide bar 403 is slidably connected inside the sleeve 401, the push plate 4 can continue to move forward. The remaining sleeves 401 continue to move forward until all the positioning rods 404 clamp the nitrogen springs in sequence. At the same time, under the action of the first spring 402 and the second spring 405, when the positioning rod 404 releases the clamping, the positioning rod 404 and the slide bar 403 will return to the initial state.

[0029] The above is only the specific implementation manner of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present disclosure can easily think of changes or substitutions, which should be covered within the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be subject to the protection scope of the claims.
