Description

Technical Field

[0001] This utility model relates to the technical field of return spring installation equipment, specifically a return spring rotary assembly equipment. Background Technology

[0002] A resilient spring is a type of spring with a special shape and structure, typically made of steel or other metals, and often exhibiting a wave-like or helical shape. Unlike traditional springs, resilient springs offer superior elasticity and durability. Their primary function is to provide support and cushioning. In the automotive industry, resilient springs are commonly used in shock absorption systems to effectively reduce bumps and vibrations during vehicle operation, improving stability and comfort. In the furniture industry, resilient springs are frequently used in mattresses and sofas to provide enhanced support and comfort.

[0003] Currently, when assembling return springs, the dimensions of the spring assembly mold are usually designed and positioned according to the product, which generally has limited versatility. When changing to springs of different sizes and specifications, the assembly mold needs to be replaced, which is not only more troublesome to operate, but also makes it easy to affect the installation accuracy of the spring by disassembling and assembling related components during replacement.

[0004] Therefore, we propose to design a return spring rotary assembly device. Utility Model Content

When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, in actual manufacturing, the three-dimensional spatial dimensions of length, width, and depth should be included.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0022] Please see Figure 1-3 This utility model provides a return spring rotation assembly device, including two fixed columns 1, with a mounting platform 2 fixedly connected to the top of the two fixed columns 1. A drive Y-axis 3 is fixedly connected to one end of the mounting platform 2, and a drive X-axis 4 is fixedly connected to the top of the movable end of the drive Y-axis 3. A height adjustment R-axis 5 is fixedly connected to one side of the movable end of the drive X-axis 4.

[0023] In this embodiment, the drive Y-axis 3, drive X-axis 4, and height adjustment R-axis 5 all include a frame. A servo motor is fixedly connected to one side of the frame, and a ball screw is fixedly connected to the drive shaft of the servo motor. The ball screw has a movable end that is slidably connected to the frame. This device uses a servo motor as the power to drive the carrier and uses a ball screw to control the assembly structure to move in a predetermined direction, thereby facilitating the repeatability and positioning accuracy of the assembly structure.

[0024] A lifting plate 6 is fixedly connected to one side of the movable end of the height adjustment R-axis 5, and a return spring assembly head is fixedly connected to the outside of the lifting plate 6.

[0025] The return spring assembly head includes a mounting frame 7. An adjustment motor 8 is fixedly connected to one side of the mounting frame 7. The drive shaft of the adjustment motor 8 passes through the mounting frame 7 and is fixedly connected to an R-axis angle adjustment seat 9. A clamp 10 is provided on one side of the R-axis angle adjustment seat 9. A clamping cylinder 11 is provided on one side of the clamp 10. A push-out cylinder 12 is fixedly connected to the top of the clamp 10. A push block 16 is fixedly connected to the telescopic end of the push-out cylinder 12. A tension shaft 13 is fixedly connected to one side of the bottom fixed frame of the push-out cylinder 12. The return spring body is provided inside the clamp 10. The return spring body includes a return spring A end 14 and a return spring B end 15.

[0026] In this embodiment, the clamp 10 includes a positioning plate fixedly connected to the R-axis angle adjustment seat 9, a clamping cylinder 11 fixedly connected to the outer wall of the positioning plate, the telescopic end of the clamping cylinder 11 passes through the positioning plate and is fixedly connected to a clamping plate, and the return spring body is located at the end position between the positioning plate and the clamping plate. The clamping cylinder 11 drives the clamping plate to move closer to the positioning plate to facilitate the positioning of the return spring body.

[0027] Among them, the return spring A end 14 and the return spring B end 15 are located at the bottom and top respectively. The tension shaft 13 corresponds to the position of the return spring B end 15. The tension shaft 13 is inserted into the spring B end to facilitate the stretching of the spring and to facilitate the push block 16 to push it out for installation.

[0028] In use, the corresponding movable ends are first moved by driving the Y-axis 3, driving the X-axis 4 and adjusting the height R-axis 5 to pick up the tension spring. The clamping cylinder 11 drives the clamping plate in the clamp 10 to move, and together with the positioning plate, clamps the return tension spring body. At this time, the tension shaft 13 is inserted into the B end 15 of the return tension spring.

[0029] Next, by adjusting the position angle of the R-axis, the motor 8 drives the R-axis angle adjustment seat 9 to rotate. The position angle is adjusted so that the return spring A end 14 is first snapped into the product. At this time, the spring clamping cylinder 11 is released. By adjusting the position of the motor 8, the tension shaft 13 drives one end of the spring to be stretched until the return spring B end 15 inserted into the tension shaft 13 is snapped into place. Then, the push cylinder 12 drives the push block 16 to push the spring out from the tension shaft 13 and snap it into the product. The spring assembly is then complete.

[0030] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
