[0030] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0031] like Figures 1-5 As shown, this embodiment provides a splicing fixture for welding an automobile upper column tube, comprising a base 1, with an adjustment clamping mechanism 2 provided on the top of the base 1;

[0032] like Figure 4As shown, the adjusting and clamping mechanism 2 includes an adjusting frame 201, a first servo motor 202, a first screw rod 203, an adjusting block 204, a second servo motor 205, a rotating column 206, a lower clamping plate 207, an upper clamping plate 208, a fastening plate 209, a bolt 210, a stabilizing groove 211 and a stabilizing block 212. The adjusting frame 201 is arranged on the top of the base 1. There are two adjusting frames 201 and they are symmetrically arranged based on the longitudinal center axis of the base 1. The first servo motor 202 is bolted to the top of the adjusting frame 201. The first screw rod 203 is vertically arranged at the output end of the first servo motor 202. The adjusting block 204 is threadedly connected to the outer wall of the first screw rod 203, the second servo motor 205 is bolted to one side of the adjusting block 204, the outer wall of the adjusting block 204 slides along the length direction of the first screw rod 203 against the inner wall of the adjusting frame 201, the rotating column 206 is coaxially arranged at the output end of the second servo motor 205, the lower clamping plate 207 is fixedly connected to one side of the rotating column 206, the upper clamping plate 208 is hinged to the top of the lower clamping plate 207, and the two fastening plates 209 are respectively fixedly connected to one side of the lower clamping plate 207 and the upper clamping plate 208. The two fastening plates 209 are tightly fitted, and the two fastening plates are fixed to the lower clamping plate 207 and the upper clamping plate 208. The plate 209 has bolt mounting holes, and the two bolts 210 are threadedly connected to the bolt mounting holes on the two fastening plates 209. The stabilizing groove 211 is opened inside the adjustment frame 201, and the stabilizing block 212 is fixedly connected to both sides of the adjustment block 204 and slidably connected to the inside of the stabilizing groove 211. When the upper column tube is assembled and welded, the first servo motor 202 is started to rotate the first screw rod 203 to adjust the height of the adjustment block 204 so that the two adjustment blocks 204 are located at different heights and match the arc-shaped upper column tube. Then, according to the curvature of the upper column tube, the second servo is started. The motor 205 causes the rotating column 206, the lower clamping plate 207 and the upper clamping plate 208 to rotate, and then the two upper clamping plates 208 are rotated to place the two ends of the upper column tube into the lower clamping plates 207 respectively, and the upper clamping plates 208 are reset to make the two fastening plates 209 fit together, and the bolts 210 are screwed in to complete the clamping of the two ends of the upper column tube. In this process, manpower operation is reduced and the stability of the upper column tube during welding is increased. When the adjusting block 204 moves, it will synchronously drive the stabilizing block 212 to slide in the stabilizing groove 211 to prevent the adjusting block 204 from rotating with the rotation of the first screw rod 203.

[0033] like Figure 3As shown, a placement slot 3 is provided inside the base 1, and the placement slot 3 is located at the bottom of the adjusting frame 201. A third servo motor 4 is bolted to one side of the base 1, and a bidirectional screw rod 5 is coaxially arranged on the output end of the third servo motor 4. The bidirectional screw rod 5 extends to the inside of the placement slot 3 and one end is rotatably connected to the inner wall of the placement slot 3. The outer wall of the bidirectional screw rod 5 is threadedly connected to two moving blocks 6, and the two moving blocks 6 are respectively located on the two sections of the thread of the bidirectional screw rod 5. The top of the moving block 6 is fixedly connected to the bottom of the adjusting frame 201, and a stabilizing rod 7 is fixedly connected to the inner wall of the placement slot 3. The two moving blocks 6 are both slidably connected to the outer wall of the stabilizing rod 7. Before clamping the upper column tube, the third servo motor 4 can be started to rotate the bidirectional screw rod 5, so that the two moving blocks 6 move in opposite directions in the placement slot 3, and the positions of the two adjusting frames 201 are adjusted to facilitate clamping of arc-shaped upper column tubes of different lengths. The stabilizing rod 7 can increase the stability of the moving block 6 during movement and prevent the moving block 6 from rotating with the rotation of the bidirectional screw rod 5.

[0034] like Figure 1 As shown, a collecting groove 8 is provided inside the base 1, and a collecting frame 9 is provided on the inner wall of the collecting groove 8. Both ends of the collecting frame 9 are fixedly connected with a protrusion 10. During welding, the collecting frame 9 can be placed in the collecting groove 8. After the waste generated during welding the column tube falls on the base 1, the operator can put it into the collecting frame 9. Later, when cleaning, the collecting frame 9 is pulled up by the protrusion 10, so that the collecting frame 9 is separated from the collecting groove 8 and the waste in the collecting frame 9 can be cleaned to prevent the waste from being scattered and inconvenient to clean.

[0035] like Figure 3 As shown, the outer wall of the bidirectional screw rod 5 is fixedly connected to a limit ring 11, which is located at the center position of both ends of the bidirectional screw rod 5. The limit ring 11 can prevent the two moving blocks 6 from touching each other and being damaged when moving towards each other.

[0036] like Figure 4 As shown, one side of the two adjustment frames 201 is fixedly connected with an extension plate 12, and the top of the extension plate 12 is fixedly connected with a telescopic rod 13. The telescopic direction of the telescopic rod 13 is parallel to the axial direction of the first screw rod 203, and the top of the telescopic rod 13 is fixedly connected to the bottom of the adjustment block 204. When the adjustment block 204 moves up and down, it will synchronously drive the telescopic rod 13 to extend and retract, and the telescopic rod 13 can increase the stability of the second servo motor 205 when it moves up and down.

[0037] like Figure 3 As shown, a support pad 14 is provided at the bottom of the base 1. The material of the support pad 14 is rubber. The rubber support pad 14 can increase the friction of the base 1 and prevent the base 1 from moving randomly during use.

[0038] likeFigure 5 As shown, the inner walls of the upper clamping plate 208 and the lower clamping plate 207 are both provided with friction pads 15, and the friction pads 15 are made of flexible material. When the upper clamping plate 208 and the lower clamping plate 207 clamp the upper column tube, the outer wall of the upper column tube will be in direct contact with the friction pads 15. The friction pads 15 made of flexible material can increase the friction between the inner walls of the upper clamping plate 208 and the lower clamping plate 207 and the outer wall of the upper column tube, and prevent the inner walls of the upper clamping plate 208 and the lower clamping plate 207 from scratching the outer wall of the upper column tube.

[0039] Specifically, when the splicing fixture for welding the upper column tube of an automobile is in use: the third servo motor 4 is started to rotate the bidirectional screw rod 5, thereby causing the two moving blocks 6 to move in opposite directions in the placement slot 3, and the positions of the two adjustment frames 201 are adjusted to facilitate clamping of arc-shaped upper column tubes of different lengths; the first servo motor 202 is started to rotate the first screw rod 203, and the height of the adjustment block 204 is adjusted so that the two adjustment blocks 204 are located at different heights and match the arc-shaped upper column tube; then, according to the curvature of the upper column tube, the second servo motor 205 is started to rotate the rotating column 206, the lower clamping plate 207 and the upper clamping plate 208 Move, then rotate the two upper clamping plates 208, place the two ends of the upper column tube into the lower clamping plates 207 respectively, so that the outer wall of the upper column tube fits with the friction pad 15, and then reset the upper clamping plate 208 to fit the two fastening plates 209, screw in the bolts 210 to complete the clamping of the two ends of the upper column tube, in this process, reduce manpower operation, and increase the stability of welding the upper column tube. After the waste generated during welding the upper column tube falls on the base 1, the operator can put it into the collection frame 9. Later, when cleaning, the collection frame 9 is pulled up by the protrusion 10, so that the collection frame 9 is separated from the collection tank 8, and the waste in the collection frame 9 can be cleaned to prevent the waste from being scattered and inconvenient to clean.

[0040] All technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
