DETAILED DESCRIPTION

[0023] 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 in conjunction with specific implementation methods.

[0024] like Figure 1 As shown, the utility model provides a technical solution: a positioning clamping tool for bolt welding of the second row seat cushion side plate of an automobile seat, comprising:

[0025] A bottom plate 1 is provided with a plurality of support plates 3 on the top of the bottom plate 1 for supporting the bottom of the second row seat cushion side plate 8, a placement hole 31 for positioning the bolt 82 is opened on the top of the support plate 3, a back plate 9 for supporting the side wall of the second row seat cushion side plate 8 is provided at a position corresponding to the support plate 3 on the top of the bottom plate 1, a positioning column 11 matching the through hole 81 on the second row seat cushion side plate 8 is provided on the side of the back plate 9 close to the second row seat cushion side plate 8, a pair of first vertical clamps 4 is provided on the top of the bottom plate 1, and a pressing plate 5 for pressing the bolt 82 is provided on the top of the telescopic end of the pair of first vertical clamps 4, the design is formed by connecting the bottom of the second row seat cushion side plate 8 with the top of the support plate 3, and then making the side wall of the second row seat cushion side plate 8 close to the back plate 9 and inserting the through hole 81 on the second row seat cushion side plate 8 into the side wall of the positioning column 11 of the back plate 9, After L-shaped positioning, the bolt 82 is then inserted through the second row seat cushion side plate 8 into the placement hole 31. Under the action of the support plate 3, the second row seat cushion side plate 8 is prevented from moving downward. Under the action of the positioning column 11, the second row seat cushion side plate 8 is prevented from moving in the vertical and longitudinal directions. Under the action of the bolt 82 and the placement hole 31, the second row seat cushion side plate 8 is prevented from moving in the horizontal and longitudinal directions, thereby completing the positioning connection between the bolt 82 and the second row seat cushion side plate 8, and then using the first vertical clamp 4 so that its telescopic end drives the pressing plate 5 to press the bolt 82, and the head of the bolt 82 cooperates with the support plate 3 to press and clamp the second row seat cushion side plate 8, ensuring that the bolt 82 is perpendicular to the connecting surface of the second row seat cushion side plate 8 to ensure the welding quality, thereby locking the positioned position, thereby facilitating the positioning and clamping between the bolt 82 and the second row seat cushion side plate 8.

[0026] Reference Figure 1 and Figure 3 A contact block 6 for pressing the side wall of the second row seat cushion side plate 8 is provided on the top of the pressing plate 5, and an avoidance groove 7 for avoiding the positioning column 11 is opened on the side of the abutment block 6 close to the second row seat cushion side plate 8. This design uses the first vertical clamp 4 to move its telescopic end to drive the pressing plate 5 to press the bottom of the second row seat cushion side plate 8 while the abutment block 6 cooperates with the back plate 9 to press the side wall of the second row seat cushion side plate 8, thereby improving the stability of the positioning clamping point.

[0027] Reference Figure 1 and Figure 2 The back plate 9 is provided with a telescopic force-applying assembly 10 for driving the positioning column 11 to be telescopically inserted into the through hole 81 on the second row seat cushion side plate 8. This design drives the positioning column 11 to be telescopic inside the through hole 81 on the second row seat cushion side plate 8 by using the telescopic force-applying assembly 10, so that when positioning the second row seat cushion side plate 8, multiple bolts 82 can be connected to the second row seat cushion side plate 8 first, and then multiple bolts 82 can be placed inside the placement hole 31 at the same time, and then the telescopic force-applying assembly 10 is used to drive the guide column 103 to connect and position with the through hole 81 of the second row seat cushion side plate 8, thereby accelerating the placement speed of the bolt 82. When the positioning column 11 cannot be telescopic, due to the protrusion of the positioning column 11, there is interference when the second row seat cushion side plate 8 is downwardly fitted and connected with the back plate 9, and the second row seat cushion side plate 8 can only be connected to the positioning column 11 on the back plate 9 first, and then the bolts 82 are passed through the bottom of the second row seat cushion side plate 8 and connected to the placement hole 31 one by one. This bolt 82 placement speed Slowly, thereby accelerating the placement speed of the bolt 82 through the setting of the telescopic force-applying component 10, further accelerating the welding speed, and improving the welding efficiency. The telescopic force-applying component 10 includes a pair of limit grooves 102 opened on one side of the top of the support plate 9, and the side wall of the support plate 9 is provided with a guide column 103 that penetrates the pair of limit grooves 102 and is connected to the positioning column 11. The top of the guide column 103 is provided with a force-applying column 101 that matches the limit groove 102, and the side wall of the support plate 9 is provided with a guide column 103 that matches the limit groove 102. The slide groove 104 is connected and matched with the force-applying column 101. The design applies force to the force-applying column 101 to make it move along the limit groove 102 and slide into the slide groove 104, so that the force-applying column 101 drives the positioning column 11 on the guide column 103 to move longitudinally along the slide groove 104 and retract inside the through hole 81 of the second-row seat cushion side plate 8, and then makes the force-applying column 101 slide into another limit groove 102, completing the locking of the positioning column 11 from the through hole 81 of the second-row seat cushion side plate 8.

An extension block 52 for pressing the bolt 82 is arranged on one side of the connecting plate 51 close to the second row seat cushion side plate 8. The abutment block 6 is embedded in the top of the extension block 52. This design drives the extension block 52 on the connecting plate 51 to press the bolt 82 through the telescopic end of the first vertical clamp 4, thereby completing the pressing and fixing of one bolt 82.

[0030] Reference Figure 1 and Figure 5 The pressing plate 5 includes a connecting plate 51 arranged on the top of the telescopic end of the first vertical clamp 4, and an extension block 52 is arranged on one side of the connecting plate 51 close to the second row seat cushion side plate 8. The extension block 52 is U-shaped, and a pair of pressing blocks 521 for pressing the bolts 82 are symmetrically arranged at the bottom of the extension block 52. A mounting block 53 is arranged at the middle position of the U-shaped groove on the inner wall of the extension block 52, and the abutment block 6 is arranged on the top of the mounting block 53. This design drives the extension block 52 on the connecting plate 51 to move through the telescopic end of the first vertical clamp 4, and a pair of pressing blocks 521 at the bottom of the extension block 52 press the pair of bolts 82, thereby completing the pressing and fixing of the pair of bolts 82. Using a first vertical clamp 4 can fix and press the two bolts 82 at the same time, thereby accelerating the speed of pressing and fixing the bolts 82.
