[0029] Example 1

[0030] like Figure 1-3 As shown: an adjustable crossbeam support device tooling, including main longitudinal beams and a hydraulic gantry. The main longitudinal beams include a left main longitudinal beam 1 and a right main longitudinal beam 2. The left main longitudinal beam 1 and the right main longitudinal beam 2 are arranged side by side and parallel, and the left main longitudinal beam 1 and the right main longitudinal beam 2 are connected together by a connecting rod 19. The distance between the left main longitudinal beam 1 and the right main longitudinal beam 2 matches the width of the subway underframe to be processed. The length of the left main longitudinal beam 1 and the right main longitudinal beam 2 are both 26 meters.

[0031] Square steel rails 3 are provided on the left and right main longitudinal beams 1 and 2 on the opposite sides. As the rails of the gantry, the square steel rails 3 are horizontally connected and the length of the square steel rails 3 is 27 meters. Limit blocks are provided at both ends of each square steel rail 3.

[0032] The hydraulic gantry includes a crossbeam 4 and two columns 5. Both columns 5 are provided with two pulleys 6 arranged on the same horizontal line. The pulleys 6 are respectively arranged on corresponding square steel rails 3. The hydraulic gantry slides on the square steel rails 3 using the pulleys 6.

[0033] A hydraulic device 7 and a telescopic pressure arm 9 with a rolling component 8 are provided on the crossbeam 4 . The hydraulic device 7 controls the rolling component 8 to drive the telescopic pressure arm 9 to reciprocate on the crossbeam 4 .

[0034] The pulley 6 slides on the square steel track 3 in the longitudinal direction, and the rolling component 8 slides on the gantry in the transverse direction, ensuring that each position can be pressed by the telescopic pressure arm 9 during the production process.

[0035] T-slot 10 tables are welded on the upper end faces of the left main longitudinal beam 1 and the right main longitudinal beam 2, and longitudinally arranged T-slot 10 is arranged on the T-slot 10 table. Each T-slot 10 table is longitudinally distributed with a clamping component, and each clamping component is provided with a downward-extending clamping arm 11 and an inward-extending tensioner 12.

[0036] Both ends of the adjustable crossbeam 13 are provided with oblong holes 14 , and the two ends of the adjustable crossbeam 13 are fixed to the left main longitudinal beam 1 and the right main longitudinal beam 2 respectively by bolts passing through the oblong holes 14 and the T-slots 10 on the T-slot 10 platform.

[0037] The adjustable crossbeam 13 is evenly distributed with threaded holes 15, and a screw rod 17 with a nut 16 is provided in each threaded hole 15. The side wall of the nut 16 is provided with a pin hole 18 for conveniently adjusting the screw rod 17 up and down. When adjusting the height of the screw rod 17, the pin is placed into the corresponding pin hole 18, and the pin is rotated to rotate the screw rod 17 so as to adjust the height of the screw rod 17.

[0038] The adjustable crossbeam 4 of the present invention is evenly distributed with spiral rods 17. The spiral rods 17 on the crossbeam 4 can be adjusted according to the shape of the workpiece, and is suitable for subway underframes with different profiles. That is, when producing subway underframes with different profiles, the spiral rods 17 at corresponding positions can be adjusted to stably and effectively support the subway underframe, reducing the production of crossbeams 4 with different profiles. The utility model has strong versatility and can adapt to avoidance in various positions to ensure the stability of the underframe support. In addition, the utility model has strong adjustability. At positions where welding is prone to deformation, the height of the spiral rods 17 at the deformed position can be adjusted to control the deformation of the welded underframe.

[0039] When working, first laser cut a corresponding cross-section template of the subway underframe, and place it on an adjustable crossbeam 13, then adjust the height of the spiral rod 17 according to the contour of the cross-section template so that it can stably support the cross-section template, and then use the same method to adjust the remaining adjustable crossbeams 13 one by one. Only after all adjustments are made can the subway underframe be placed. After the subway underframe is placed, the clamping arm 11 that extends downward and upward and the tightening device 12 that extends inward are used to fix the two ends of the subway underframe. After fixation, the gantry is moved according to the required welding position. After reaching the predetermined position, the hydraulic device 7 is used to control the rolling component 8 to drive the pressure arm to move to the position where it needs to be fixed on the crossbeam 4, and the pressure arm of the rolling component 8 is used to clamp and fix the top of the subway underframe, which is convenient for subsequent processing of the subway underframe.

[0040] The difference from the first embodiment is that a nylon block is provided on the nut 16, which not only ensures the close fit between the subway chassis and the spiral rod 17, but also prevents the subway chassis from being bumped and scratched.
