Description

Technical Field

[0001] The utility model relates to the field of automobile seat welding assistance, in particular to a welding positioning device for a side panel bracket of an automobile seat backrest. Background Art

[0002] The side panels of car seat backs require welding brackets. In existing technology, workers manually weld the brackets to the side panels after the arc welding robot completes the work. This approach has drawbacks: workers need separate welding machines, welding tongs, and exhaust platforms. Furthermore, due to varying welding skills, weld quality is inconsistent, and manual welding takes a long time, impacting production efficiency. Summary of the Invention

[0003] In view of the deficiencies of the existing technology, the present invention has developed a device for welding and positioning the side panel bracket of a car seat backrest. The technical solution adopted by the present invention is: a device for welding and positioning the side panel bracket of a car seat backrest, characterized in that it comprises a workbench 1, a front seat positioning block 2, a rear seat positioning block 3, a bracket positioning assembly 4 and an electrode 16; the front seat positioning block 2, the rear seat positioning block 3, the bracket positioning assembly 4 and the electrode 16 are respectively arranged on the workbench 1; the bracket positioning assembly 4 comprises a support block 5, a column 12, an upper adjustment plate 10 and a lower adjustment plate 11; the lower adjustment plate 11 is provided with a third adjustment hole 14, a bolt passes through the third adjustment hole 14 and is threaded with the workbench 1 Connection; a second adjustment hole 13 is provided on the upper adjustment plate 10, and the bolt passes through the second adjustment hole 13 and is threadedly connected to the lower adjustment plate 11; the column 12 is fixedly connected to the upper adjustment plate 10; a first adjustment hole 9 is provided on the column 12, and the bolt passes through the first adjustment hole 9 and is threadedly connected to the support block 5; the upper part of the support block 5 has a supporting ridge 6; a positioning groove 18 is provided in the side wall of the support block 5; the threaded rod 7 is threadedly connected to the support block 5 and passes through the support block 5; the lower end of the threaded rod 7 is fixedly connected to the knob 8.

[0004] The benefits of the present invention are as follows: since the support block is used to support and position the bracket, the side panels of the car seat backrest and the bracket are welded by an arc welding robot, which avoids the unstable welding quality caused by workers' manual welding, saves the cost of manual welding equipment, and improves production efficiency.

DETAILED DESCRIPTION

[0013] 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.

[0014] like Figures 1 to 3As shown, the utility model is a welding positioning device for a car seat back side panel bracket, which includes: a workbench 1, a seat front positioning block 2, a seat rear positioning block 3, a bracket positioning assembly 4 and an electrode 16; the seat front positioning block 2, the seat rear positioning block 3, the bracket positioning assembly 4 and the electrode 16 are respectively arranged on the workbench 1; the bracket positioning assembly 4 includes a support block 5, a column 12, an upper adjustment plate 10 and a lower adjustment plate 11; the lower adjustment plate 11 is provided with a third adjustment hole 14, a bolt passes through the third adjustment hole 14 and is threadedly connected to the workbench 1; the A second adjustment hole 13 is provided on the upper adjustment plate 10, and a bolt passes through the second adjustment hole 13 and is threadedly connected to the lower adjustment plate 11; the column 12 is fixedly connected to the upper adjustment plate 10; a first adjustment hole 9 is provided on the column 12, and a bolt passes through the first adjustment hole 9 and is threadedly connected to the support block 5; a support ridge 6 is provided on the upper part of the support block 5; a positioning groove 18 is provided in the side wall of the support block 5; a threaded rod 7 is threadedly connected to the support block 5 and passes through the support block 5; the lower end of the threaded rod 7 is fixedly connected to the knob 8.

[0015] When doing specific operations, such as Figures 3 to 5 As shown, the worker first places the bracket 15 on the support block 5 to complete the positioning, ensuring that the bracket 15 is locked Figure 3 The upper end of the bracket 15 is pressed on the support ridge 6; the lower end is pressed on the threaded rod 7. Figure 6 As shown, the worker installs the seat back side panel 17 into the seat front positioning block 2 and the seat rear positioning block 3 to complete the positioning of the seat back side panel 17. At this time, the lower end of the seat back side panel 17 contacts the electrode 16 and presses on the bracket 15 with its own weight. The worker uses the utility model to complete the positioning of the bracket 15 and the seat back side panel 17 to be welded and proceed to the next welding process.

[0016] When the worker needs to adjust the height of the support block 5, Figure 2 As shown, the worker loosens the two bolts above the first adjustment hole 9, and then tightens the bolts after the adjustment is completed. Figure 3 As shown, a worker can adjust the relative positions of the lower adjustment plate 11 and the upper adjustment plate 10 by loosening the bolts to achieve position adjustment of the support block 5 in the three directions of XYZ.

[0017] like Figure 7 As shown, when the upper end of the bracket 15 is not completely in contact with the seat back side panel 17, the worker rotates the knob 8 to adjust the extension and contraction of the threaded rod 7, thereby adjusting the upper end of the bracket 15 to a state of close contact with the seat back side panel 17 to ensure welding quality.

[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.
