Description

Technical Field

[0001] The invention relates to the field of automatic installation, in particular to an automatic installation mechanism for a special-shaped torsion spring. Background Art

[0002] In the 3C industry and server switch industry, springs are widely used due to the numerous internal reset and extension / retraction mechanisms involved in products. Torsion springs, also known as torsion springs, are one of the most complex spring types, with a wide variety of styles and the most complex theoretical requirements for their design. Torsion springs play a crucial role in products. Their ends are fixed to other components. When the components rotate about the spring's center, the spring pulls them back to their original position, generating torque or rotational force. Torsion springs can store and release angular energy or statically fix a device by rotating a lever arm around its central axis. However, installing torsion springs in products has always been challenging. To maintain the spring's rebound force, the spring must be forced into place, making manual installation difficult and often impossible. To date, no suitable and universal torsion spring installation method or mechanism has been established in the industry. Summary of the Invention

[0029] The following is a detailed description of an automatic installation mechanism for special-shaped torsion springs of the present invention with reference to the accompanying drawings.

[0030] like Figures 1 to 7 As shown, an automatic installation mechanism for a special-shaped torsion spring of the present invention includes a support assembly 1, a toggle cylinder assembly 2, a forward-pushing cylinder assembly 3, a toggle-down cylinder assembly 4 and a forward-pushing-down cylinder assembly 5. The toggle cylinder assembly 2 is provided with two groups, and the two groups of toggle cylinders are symmetrically arranged. The toggle cylinder is slidingly connected to the support assembly 1, and the toggle-down cylinder assembly 4 is arranged at the lower part of the toggle cylinder assembly 2 and is connected to the support assembly 1. The telescopic end of the toggle-down cylinder assembly 4 is connected to the bottom of the toggle cylinder assembly 2. The telescopic movement of the toggle-down cylinder assembly drives the toggle cylinder assembly to slide up and down along the support assembly, thereby realizing the adjustment of the height of the toggle cylinder assembly according to the different installation positions of the torsion spring; the forward-pushing cylinder assembly 3 is provided with two groups, and the two groups of forward-pushing cylinder assemblies are symmetrically arranged, and two symmetrically arranged torsion springs can be installed at the same time, thereby improving work efficiency. The forward-pushing cylinder assembly 3 is connected to the support plate 15 of the support assembly 1, and the forward-pushing and lowering cylinder assembly 4 is arranged below the support plate of the support assembly 1. The extension and contraction of the forward-pushing and lowering cylinder 5 drives the support plate 15 to move up and down, and the up and down movement of the support plate drives the up and down movement of the forward-pushing and lowering cylinder, thereby achieving height adjustment of the forward-pushing cylinder assembly. The forward-pushing cylinder assembly is connected to the support plate via a fixing bolt 33, and the angle of the forward-pushing cylinder can be adjusted by the fixing bolt 33, so that the forward-pushing fork of the forward-pushing cylinder assembly can accurately push the torsion spring leg to prevent slipping when pushing the torsion spring leg.

[0031] like Figure 6 As shown, the support assembly 1 includes a support frame 11, a rear side plate 12, a base 13 and a support plate 15. The support frame 11 is two vertical columns. The rear side plate 12 is arranged at the rear of the two columns. One side of the rear side plate 12 is connected to one column, and the other side is connected to the other column. The support plate 15 is slidably connected to the front side of the rear side plate 12. The upper part of the front side of the two columns is provided with a slide rail 14. The cylinder assembly 2 can be slid up and down along the slide rail to adjust different heights. The lower ends of the two columns are respectively provided with a base 13, which can improve the overall stability of the support assembly. The front ends of the rear side plate 12 are respectively provided with a slide rail 14, and the rear ends of the support plate 15 are respectively provided with a slider 24, which is slidably connected to the corresponding slide rail 14.

[0032] like Figure 7As shown, the forward thrust cylinder assembly 3 includes a forward thrust cylinder body 31, a forward thrust fork 32 and a thrust stop 34. The bottom of the forward thrust cylinder body 31 is connected to the support plate 15 of the support assembly through a fastener. The fastener is a fastening bolt. The angle of the forward thrust cylinder assembly can be adjusted by loosening the fastening bolt. The forward thrust fork 32 is connected to the telescopic rod of the forward thrust cylinder body 31. The rear end of the forward thrust cylinder body is provided with a thrust stop for controlling the extension length of the cylinder telescopic rod.

[0033] In order to improve the accuracy of the forward push cylinder assembly in pushing the torsion spring, a V-shaped groove is provided at the free end of the forward push fork hand 32 to cooperate with the torsion spring leg. The torsion spring leg cooperates with the V-shaped groove of the forward push fork hand.

[0034] like Figure 3 As shown, the toggle cylinder assembly 2 includes a toggle cylinder body 21, a toggle handle 22, a mounting support plate 23, a slider 24, a cylinder downward stopper 25, and a cylinder downward body stopper 26. The toggle cylinder body 21 is connected to the mounting support plate 23, which is slidably connected to the support assembly 1. The toggle handle 22 is connected to the telescopic cylinder rod of the toggle cylinder body 21. The telescopic cylinder rod extends forward, simultaneously driving the toggle handle 22 to move forward. The toggle handle applies force to the legs of the torsion spring, toggling one of the legs of the torsion spring to the back plate, so that the leg of the torsion spring abuts against the back plate, at which point the position of the torsion spring is fixed. The cylinder downward stopper 25 is slidably connected to the side of the mounting support plate 23, and is movably connected to the cylinder downward body stopper 26. The cylinder downward body stopper is fixedly connected to the side wall of the support assembly. The cylinder downward stopper can limit the downward distance of the mounting support plate along the slide rail, thereby preventing the toggle cylinder from excessively moving downward. The cylinder downward body stopper can play the role of buffering for the cylinder downward stopper. The rear side wall of the mounting support plate is provided with a slider, which is slidably connected to the slide rail on the support assembly.

[0035] like Figure 4 As shown, the toggle lowering cylinder assembly 4 includes a toggle lowering cylinder body 41, a telescopic rod 42, a mounting plate 43 and a mounting plate 2 44. The upper end of the toggle lowering cylinder body 41 is connected to the mounting plate 1 43, and the mounting plate 1 43 is fixedly connected to the rear side plate of the support assembly 1. One end of the telescopic rod passes through the mounting plate 1 and is connected to the cylinder rod of the toggle lowering cylinder body. The other end of the telescopic rod is fixedly connected to the bottom wall of the mounting plate 2 44. The upper part of the mounting plate 2 44 is connected to the mounting support plate 23 of the toggle cylinder assembly 2. The extension and retraction of the telescopic rod drives the mounting plate 2 and the toggle cylinder assembly to move up and down, thereby adjusting the height of the toggle cylinder assembly.

[0036] like Figure 5As shown, the forward pushing and descending cylinder assembly 5 includes a forward pushing and descending cylinder body 51, a telescopic rod 2 52, a mounting plate 3 53 and a mounting plate 4 54. The upper end of the forward pushing and descending cylinder body 51 is connected to the bottom wall of the mounting plate 3 53, and the side wall of the mounting plate 3 53 is connected to the lower part of the rear side plate 12 of the support assembly. One end of the telescopic rod 2 52 passes through the mounting plate 3 53 and is connected to the telescopic cylinder body of the forward pushing and descending cylinder body 51, and the other end of the telescopic rod 2 52 is connected to the mounting plate 4 54, and the mounting plate 4 54 is connected to the lower part of the support plate 15. The extension and retraction of the telescopic rod drives the support plate and the forward pushing cylinder assembly mounted on the support plate to move up and down along the slide rail on the support assembly.

[0037] The side wall of one end of the support frame 11 connected to the base 13 is provided with a plurality of reinforcing ribs to improve the reliability and stability of the support assembly.

[0038] The torsion spring is installed on the torsion spring installation positioning column. When installing the torsion spring, the torsion spring leg needs to be close to the torsion spring installation backrest. The true working position of the torsion spring should be on the torsion spring action leg (compressed state). Therefore, during automated installation, it should be noted that the torsion spring needs to be installed in a compressed state.

[0039] First, according to the installation position of the torsion spring, adjust the height of the toggle cylinder by toggling the lowering cylinder, and adjust the angle of the forward push cylinder through the fasteners of the forward push cylinder assembly to ensure that when the forward push cylinder is extended, the forward push fork can accurately push the torsion spring leg. During operation, the forward push lowering cylinder is extended, and the pallet with the product enters the machine. After the product in place switch detects the product, the mechanism starts to move, and the lowering cylinder is adjusted to the required height of the toggle cylinder. The toggle cylinder is ready to toggle the torsion spring, and the toggle handle is used to toggle the torsion spring to the torsion spring installation backrest position. The position of the torsion spring is fixed. At this time, the action leg of the torsion spring has been exposed to the position to be pushed. The cylinder of the forward push cylinder assembly is extended, and the action leg of the torsion spring in the relaxed state is pushed to the action leg in the compressed state by the forward push fork. At this time, the torsion spring is in the waiting working position, and then the product parts to be installed are installed to this position to achieve the purpose of automated installation of the torsion spring.
