Description

Technical Field

[0001] The utility model relates to a tool, in particular to a seat torsion spring assembly device with a height adjuster. Background Art

[0002] As passengers' requirements for driving comfort become increasingly higher, multi-functional seats have become popularized from high-end models to standard models. Seats with height adjusters have been widely praised by users. Torsion springs are key components of seats with height adjusters and require a certain amount of pre-torque during assembly. During the assembly process, one person needs to use torque to rotate the torsion spring, and one person is responsible for assembling it to a fixed position. The two people need to work together to complete the process. The labor intensity is high, the work efficiency is low, and it cannot meet the production plan requirements. Summary of the Invention

[0003] In order to solve the above problems, the purpose of the utility model is to provide a torsion spring assembly device for a seat with a height adjuster.

[0004] To achieve the above-mentioned purpose, the technical solution of the utility model is: a torsion spring assembly device for a seat with a height adjuster, comprising a base plate and two manual pressing clamps installed on the left and right sides of one end of the base plate surface, a first positioning block is fixed to the outer base plate surface of each manual pressing clamp, a vertical cylinder support is provided at the center of the other end of the base plate surface, a cylinder is fixed to the top of the cylinder support, a horizontal pressure plate is fixed to the telescopic end of the cylinder, and the second positioning block is fixed on the base plate surface between the cylinder support and the first positioning block.

[0005] Furthermore, the top of the cylinder support is a horizontal fixed plate, the cylinder is fixed on the surface of the fixed plate, the pressure plate is fixed on a slider slidably arranged on the surface of the fixed plate, and the slider is arranged on a slide rail.

[0006] Furthermore, reinforcing plates with triangular cross-sections are respectively provided at the front and rear of the cylinder support fixing plate.

[0007] Furthermore, the bottom plate support is fixed to the top of the supporting legs, and the bottoms of adjacent supporting legs are fixedly connected by a cross bar.

[0008] Furthermore, freely rotatable wheels are fixed to the bottom supports of the legs.

[0009] Furthermore, adjacent cross bars at the bottom of the legs are fixedly connected via a connecting plate.

[0010] Furthermore, the cylinder support is higher than the first positioning block and the second positioning block.

[0011] Through the above arrangement, when installing the seat frame, the utility model fixes the mounting holes at the bottom of the seat frame to the corresponding positioning columns of the first positioning block and the second positioning block. The cylinder rod of the cylinder drives the pressure plate to retract to the initial position. When work is required, the cylinder rod drives the pressure plate to extend to the designed position, pressing the seat frame to facilitate the installation of the height adjuster torsion spring. That is, a combination of pneumatic and manual compression is adopted. The seat frame is first adjusted to an angle and then fixed to the base plate. The assembly is completed under the premise that the height adjuster torsion spring is not subjected to torsion. After the pressure of the cylinder pressure plate is released, the seat frame automatically resets, and the height adjuster torsion spring naturally generates pre-tightening torque, which facilitates the installation of the height adjuster torsion spring. The utility model has the following advantages:

[0012] 1. The telescopic end of the cylinder of the utility model is fixed with a horizontal pressure plate, and the bottom plate surface between the cylinder support and the first positioning blocks on each side is respectively fixed with a vertical second positioning block. Through reasonable optimization, the installation of the torsion spring is more convenient and quick, which reduces the labor intensity of employees and improves production efficiency.

[0013] 2. The utility model solves the production bottleneck, meets the production plan requirements, and has higher assembly efficiency of the height adjuster seat torsion spring. BRIEF DESCRIPTION OF THE DRAWINGS

A first positioning block 2 is fixed to the outer surface of the base plate 7 of each manual pressure clamp 3. A vertical cylinder support 4 is provided at the center of the other end of the surface of the base plate 7. A cylinder 5 is fixed to the top of the cylinder support 4. A horizontal pressure plate 6 is fixed to the telescopic end of the cylinder 5. The second positioning block 1 is fixed on the surface of the base plate 7 between the cylinder support 4 and the first positioning block 2, and the cylinder support 4 is higher than the first positioning block 2 and the second positioning block 1.

[0018] The top of the cylinder support 4 is a horizontal fixed plate, the cylinder 5 is fixed on the surface of the fixed plate, the pressure plate 6 is fixed on the slider 10 slidingly set on the surface of the fixed plate, the slider 10 is slidably set on the slide rail, and the front and back of the bottom of the fixed plate of the cylinder support 4 are respectively provided with reinforcing plates 11 with a triangular cross-section.
