Description

Technical Field

[0001] The utility model relates to the field of automobile seat assembly, in particular to a pressing device for a lower transverse tube tooth plate bracket of an automobile seat. Background Art

[0002] The lower cross tube of a car seat requires a bracket and tooth plate to be pressed into place at each end. In the existing technology, workers first manually assemble the bracket and tooth plate to the ends of the lower cross tube, aligning the raised points on the lower cross tube with the corresponding notches on the bracket and tooth plate. A hydraulic mechanism is then installed to position and complete the press-in process. This is disadvantageous in that the entire assembly process relies entirely on visual inspection and manual labor, which is not only inefficient but also often results in the raised points and notches not matching properly. Even if the matching is accurate, the movement of parts during installation into the hydraulic mechanism affects the subsequent press-in process, resulting in scrapped parts and increased production costs. Summary of the Invention

[0003] In view of the deficiencies of the existing technology, the present invention develops a device for pressing the tooth plate bracket under the horizontal tube of an automobile seat. The technical solution adopted by the present invention is: a device for pressing the tooth plate bracket under the horizontal tube of an automobile seat, characterized in that it includes a workbench 1, a bracket pressing assembly 2, a tooth plate pressing assembly 3, a first horizontal tube clamp 10, a second horizontal tube clamp 11, a first positioning fixture 12 and a second positioning fixture 13; the bracket pressing assembly 2 includes a first hydraulic cylinder 4, a first guide rail 6 and a bracket profiling pressure head 8; the first hydraulic cylinder 4 and the first guide rail 6 are respectively fixedly arranged on the workbench 1; the bracket profiling pressure head 8 is fixedly connected to the piston rod of the first hydraulic cylinder 4 and is slidably connected to the first guide rail 6; the tooth plate pressing assembly 3 includes a second hydraulic cylinder 5, a second guide rail 7 and a tooth plate profiling pressure head 9; the tooth plate profiling pressure head 9 is connected to the The piston rod of the second hydraulic cylinder 5 is fixedly connected and slidingly connected to the second guide rail 7; the first cross tube clamp 10 and the second cross tube clamp 11 are respectively fixedly arranged on the workbench 1; the first positioning fixture 12 includes a first card 14 and a first base 16; the first base 16 is fixedly connected to the workbench 1; the first card 14 is hinged to the first base 16; the second positioning fixture 13 includes a second card 15 and a second base 17; the second base 17 is fixedly connected to the workbench 1; the second card 15 is hinged to the second base 17; the first magnet 18 is arranged in the bracket profiling head 8; the second magnet 21 is arranged in the toothed plate profiling head 9.

[0004] The benefits of the present invention are as follows: since the first positioning fixture and the second positioning fixture are used to locate the convex points on the lower transverse tube, the transverse tube fixture is used to clamp the lower transverse tube after the positioning is completed, and the bracket and the tooth plate are pressed into the lower transverse tube in conjunction with the contour pressing head, the inaccurate matching caused by workers visually and manually matching the convex points of the lower transverse tube with the gaps of the bracket and the tooth plate is avoided, and the lower transverse tube is clamped after the convex points on the lower transverse tube are positioned, thereby avoiding the movement of parts during the manual installation of the hydraulic mechanism and the waste of production efficiency caused by secondary adjustment of parts.

DETAILED DESCRIPTION

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0015] Reference Figures 1 to 3 The utility model is a device for pressing a tooth plate bracket under a horizontal tube of a car seat, comprising: a workbench 1, a bracket pressing assembly 2, a tooth plate pressing assembly 3, a first horizontal tube clamp 10, a second horizontal tube clamp 11, a first positioning fixture 12 and a second positioning fixture 13; the bracket pressing assembly 2 comprises a first hydraulic cylinder 4, a first guide rail 6 and a bracket profiling pressure head 8; the first hydraulic cylinder 4 and the first guide rail 6 are respectively fixedly arranged on the workbench 1; the bracket profiling pressure head 8 is fixedly connected to the piston rod of the first hydraulic cylinder 4 and is slidably connected to the first guide rail 6; the tooth plate pressing assembly 3 comprises a second hydraulic cylinder 5, a second guide rail 7 and a tooth plate profiling pressure head 9; the tooth plate profiling pressure head 9 and the second hydraulic cylinder 5 is fixedly connected to the piston rod and is slidably connected to the second guide rail 7; the first cross tube clamp 10 and the second cross tube clamp 11 are respectively fixedly arranged on the workbench 1; the first positioning fixture 12 includes a first card 14 and a first base 16; the first base 16 is fixedly connected to the workbench 1; the first card 14 is hinged to the first base 16; the second positioning fixture 13 includes a second card 15 and a second base 17; the second base 17 is fixedly connected to the workbench 1; the second card 15 is hinged to the second base 17; the first magnet 18 is arranged in the bracket profiling head 8; the second magnet 21 is arranged in the tooth plate profiling head 9.

[0016] For specific operations, refer to Figures 4 to 7 .like Figure 4 As shown, the worker first installs the bracket 19 into the bracket contour pressing head 8. Figure 2 The first magnet 18 shown in FIG can attract the bracket 19 to prevent it from falling; Figure 5 As shown, the worker then installs the tooth plate 20 into the tooth plate profiling press head 9. Figure 3 The second magnet 21 shown in FIG can attract the tooth plate 20 to prevent it from falling. Figure 6 As shown, the worker installs the lower cross pipe 22 into the first cross pipe fixture 10 and the second cross pipe fixture 11, and removes the first positioning fixture 12 and the second positioning fixture 13 from the Figure 1 The position shown in is flipped about 180°, Figure 7 Taking the positioning of the protrusion 23 of the lower transverse tube by the second card 15 as an example, the worker can rotate the lower transverse tube so that the protrusion 23 is close to the second card 15 to complete the positioning of the protrusion 23 of the lower transverse tube. The positioning principle of the first card 14 is exactly the same. Figure 6As shown, there are convex rings on both sides of the lower cross tube, and the first positioning fixture 12 and the second positioning fixture 13 are respectively clamped on the outside of the convex rings on both sides of the lower cross tube 22, which also completes the axial positioning of the lower cross tube 22. After the lower cross tube 22 is positioned, as shown in FIG. Figure 6 As shown, the worker uses the first cross pipe clamp 10 and the second cross pipe clamp 11 to clamp the lower cross pipe 22. Figure 8 After positioning the lower transverse tube 22, the worker rotates the first and second positioning fixtures 12 and 13 180° to their initial positions. The worker then simultaneously operates the first and second hydraulic cylinders 4 and 5, causing the bracket profiling head 8 and tooth plate profiling head 9 to move toward each other, pressing the bracket 19 and tooth plate 20 into the ends of the lower transverse tube 22.

[0017] The bracket, tooth plate and lower transverse tube adopt interference fit; the cooperation of the protrusion and the notch ensures that the bracket, tooth plate and lower transverse tube do not move relative to each other. The above two points are common knowledge.

[0018] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
