Description

Technical Field

[0001] The utility model relates to the technical field of automobile seats, in particular to a welding device for a rear linkage tube tooth plate of an automobile seat cushion. Background Art

[0002] The car seat is an important part of the car and is also the part that comes into direct contact with the driver and passengers. It can provide a comfortable experience for the driver and passengers and is more related to their safety. The rear linkage tube of the seat cushion is an important component of the seat. It ensures the strength of the seat cushion and also connects the backrest. The backrest supports the back, waist, and head of the driver and passengers. Everyone is fat, thin, tall, and short. When sitting on the seat, you need to adjust the backrest to get a comfortable sitting posture. The backrest angle adjustment needs to be achieved in conjunction with the tooth plate. The rotation of the tooth plate drives the backrest adjustment to give the driver and passengers a comfortable experience. The tooth plate is one of the most important parts. It must be welded firmly and ensure that the tooth plate does not deform after welding and runs smoothly. In addition, the angle between the tooth plate and the rear linkage tube cannot deviate.

[0003] In order to achieve this goal, it is necessary to have a positioning and clamping mechanism for the tooth plate to ensure the angle of the tooth plate and to protect the teeth in the tooth plate from damage, so that it has good durability and reusability.

[0004] The existing positioning method is to insert two pins with particularly thin diameters into the tooth grooves of the tooth plate, and then support and press them. The disadvantage of this mechanism is that the pins are easy to break, and the tooth plate and the rear linkage pipe will be twisted after welding, and the possible twisting is random and always in an unstable state. Utility Model Content

[0005] The utility model aims to provide a welding device for a rear linkage tube tooth plate of an automobile seat cushion in view of the above-mentioned deficiencies and defects of the prior art, so as to solve the above-mentioned problems.

[0006] The technical problem solved by the present invention can be achieved by adopting the following technical solutions:

[0007] A welding device for a rear linkage tube and toothed plate of an automobile seat cushion is characterized in that it comprises a clamp arranged on a frame for placing and fixing the rear linkage tube, a positioning mechanism arranged on the frame for placing and positioning the toothed plate, and a plurality of clamping mechanisms arranged on the frame for clamping the rear linkage tube and the toothed plate.

[0008] In a preferred embodiment of the present invention, the positioning mechanism includes a first positioning pin for placing the tooth groove of the tooth plate and a second positioning pin for positioning the tooth plate, and a second telescopic cylinder is provided on the second positioning pin.

[0009] In a preferred embodiment of the present invention, the plurality of clamping mechanisms include a first clamping mechanism for pressing the tooth plate onto a support block, a second clamping mechanism for pressing the tooth plate into engagement with a first positioning pin, and a third clamping mechanism and a fourth clamping mechanism respectively arranged on both sides of the tooth plate and for clamping the tooth plate.

[0010] Due to the adoption of the above technical solution, the beneficial effects of the utility model are: the positioning accuracy of the rear linkage pipe and the tooth plate is high, the defect rate is reduced, the cost is reduced, and the production efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0013] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below.

[0014] See also Figure 1 The illustrated welding device for a rear linkage tube and tooth plate of an automobile seat cushion comprises a clamp (not shown in the figure) arranged on a frame for placing and fixing a rear linkage tube 1, a positioning mechanism 100 arranged on the frame for placing and positioning a tooth plate 2, and a plurality of clamping mechanisms 200 arranged on the frame for clamping the rear linkage tube 1 and the tooth plate 2.

[0015] The positioning mechanism 100 includes a first positioning pin 110 for placing the tooth groove of the tooth plate 2 and a second positioning pin 120 for positioning the tooth plate 2, and a second telescopic cylinder 121 is provided on the second positioning pin 120. Specifically, the second telescopic cylinder 121 controls the telescopic movement of the second positioning pin 120, and the second positioning pin 120 and the second telescopic cylinder 121 are connected to the frame through the connecting plate 10.

[0016] The plurality of clamping mechanisms 200 include a first clamping mechanism 210 for clamping the tooth plate 2 on the support block 300, a second clamping mechanism 220 for clamping the tooth plate 2 and the first positioning pin 110, and a third clamping mechanism 230 and a fourth clamping mechanism 230 respectively arranged on both sides of the tooth plate 2 and clamping the tooth plate 2. In this embodiment, the first clamping mechanism 210 and the second clamping mechanism 220 are fixed on the frame, while the third clamping mechanism 230 and the fourth clamping mechanism 240 are fixed on the connecting plate 10.
