The two oblique beams 12 are used for mounting the bumper 15 at the end remote from the longitudinal beam 11.
The frame front section assembly welding tool provided in this embodiment includes a base 100, a first positioning module 200, a second positioning module 300, a third positioning module 400 and a fourth positioning module 500. In this embodiment, the width direction of the base 100 is defined as a first direction X, the length direction of the base 100 is defined as a second direction Y, the height direction of the base 100 is defined as a third direction Z, and the first direction X, the second direction Y, and the third direction Z are perpendicular to each other. The first positioning module 200, the second positioning module 300, the third positioning module 400 and the fourth positioning module 500 are arranged along the second direction Y.
The first positioning module 200 includes two diagonal beam positioning mechanisms 230 rotatably adjustable about an axis located in a vertical direction, and the two diagonal beam positioning mechanisms 230 are aligned along a first direction X and are used for positioning and supporting the corresponding diagonal beams 12. The second positioning module 300 is disposed on the base 100 and is used for positioning and adjusting the leg support 13. The third positioning module 400 is disposed on the base 100 and is used for positioning and adjusting the engine bracket 14. The fourth positioning module 500 includes a centering driving mechanism 520 disposed on the base 100 and two longitudinal beam positioning mechanisms 530 disposed on the centering driving mechanism 520 along the first direction X, where the centering driving mechanism 520 is used for synchronously driving the two longitudinal beam positioning mechanisms 530 to position and clamp the corresponding longitudinal beam 11.
When the front section 10 of the frame is assembled, the two inclined beams 12 are positioned and supported by the two inclined beam positioning mechanisms 230 by rotating the angles of the two inclined beam positioning mechanisms 230 to adapt to the shape of the two inclined beams 12 after welding; the distance between the two longitudinal beam positioning mechanisms 530 in the first direction X is adjusted by the centering driving mechanism 520 in the fourth positioning module 500 to adapt to the width dimension of the two longitudinal beams 11 after welding and forming, and the longitudinal beams 11 are positioned and clamped by the two longitudinal beam positioning mechanisms 530 respectively, so that the movement of the longitudinal beams 11 is limited; and then the second positioning module 300 is used for positioning and adjusting the supporting leg bracket 13 so as to enable the supporting leg bracket 13 to be placed at a preset position, the third positioning module 400 is used for positioning and adjusting the engine bracket 14 so as to enable the engine bracket 14 to be placed at the preset position, and finally the assembled longitudinal beam 11, the oblique beam 12, the supporting leg bracket 13 and the engine bracket 14 are welded and connected. Therefore, the frame front section assembly welding tool provided by the embodiment performs the whole welding operation after the longitudinal beam 11, the oblique beam 12, the supporting leg bracket 13 and the engine bracket 14 are positioned, the positioning is reliable, the welding quality is guaranteed, the welding deformation is effectively avoided, and the product quality is guaranteed.
In order to more clearly describe the technical scheme of the application, the following is a description of each module in the welding tool for assembling the front section of the frame, which is provided by the embodiment, specifically as follows:
referring to fig. 2, 3 and 4, the first positioning module 200 further includes a first base 210 and a locking mechanism 220. The first base 210 is disposed on the base 100, and two rotatable and adjustable diagonal beam positioning mechanisms 230 are further disposed on the first base 210. Each of the diagonal beam positioning mechanisms 230 is provided with a locking mechanism 220, and the locking mechanism 220 is used for locking the diagonal beam positioning mechanism 230 on the first base 210 so as to limit the rotation adjustment of the diagonal beam positioning mechanism 230. Thus, when the diagonal beam positioning mechanism 230 needs to be adjusted, the locking of the diagonal beam positioning mechanism 230 by the locking mechanism 220 is released, then the diagonal beam positioning mechanism 230 is rotated to a preset position, and then the diagonal beam positioning mechanism 230 is locked on the first base 210 by the locking mechanism 220.
Alternatively, the locking mechanism 220 may be selected as a bolt assembly or a latch member.
The tilt beam positioning mechanism 230 includes a rotating base 231, a support frame 232, a first positioning bracket 233, and an electromagnetic adsorption assembly 234. Wherein the rotation seat 231 is rotatably provided on the first seat 210, such as a rotation of a shaft and a hole or a rotation of a shaft and a bearing housing. Thereby, the rotation seat 231 is rotatable about an axis in the vertical direction. The supporting frame 232 and the first positioning frame 233 are both disposed on the rotating base 231, so as to be rotatable and adjustable together with the rotating base 231.
Further, a supporting pad 2320 is disposed on the supporting frame 232, and the supporting pad 2320 is used for abutting against the bottom of the oblique beam 12. The first positioning bracket 233 is disposed on the rotating base 231 and located on one side of the supporting frame 232, specifically, the first positioning bracket 233 is located on one side of the supporting frame 232 away from the other diagonal beam positioning mechanism 230, and is used for abutting against the sidewall of the diagonal beam 12. Thus, when the inclined beam 12 is positioned and clamped, the inclined beam 12 is firstly placed on the supporting cushion 2320 to be supported, and then the side wall of the inclined beam 12 is abutted against the first positioning bracket 233, so that the positioning of the inclined beam 12 is completed.
In some embodiments, the support pads 2320 are detachably connected to the support frame 232, so that when the diagonal beams 12 with different specifications are required to be installed, the support pads 2320 with different specifications are replaced for adapting. Alternatively, the detachable connection may be a plug connection, a snap connection, a threaded connection, a screw connection, or the like. It is to be understood that the foregoing is illustrative only and is not to be construed as limiting the scope of the present application.
The electromagnetic adsorption assembly 234 is disposed on the first positioning bracket 233, and the electromagnetic adsorption assembly 234 is used for selectively magnetically attracting the oblique beam 12. It will be appreciated that when the positioning of the diagonal member 12 is completed, the electromagnetic adsorption assembly 234 is energized, and the electromagnetic adsorption assembly 234 adsorbs the diagonal member 12 (the diagonal member 12 is made of magnetically attractable metal), thereby restricting the movement of the diagonal member 12 on the support pads 2320. Another tilt beam 12 is then mounted to another tilt beam positioning mechanism 230 in the same manner.
Further, electromagnetic adsorption assembly 234 includes an electromagnetic member 2340, a first adjusting screw 2341, and a first guide shaft 2342. The electromagnetic member 2340 is arranged at one side of the first positioning bracket 233 for abutment against the oblique beam 12. One end of the first adjusting screw 2341 is movably connected with the electromagnetic member 2340, and the other end of the first adjusting screw penetrates through the first positioning bracket 233 and is in threaded fit with the first positioning bracket 233. One end of the first guide shaft 2342 is connected to the electromagnetic member 2340, and the other end penetrates the first positioning bracket 233 and is slidably engaged with the first positioning bracket 233. As such, solenoid 2340 may be driven to extend or retract by twisting first adjustment screw 2341 to fine tune solenoid 2340 in a first direction such that solenoid 2340 is able to approach and attract the side walls of diagonal beam 12.
In some embodiments, an arc-shaped guiding chute 2310 is provided on the rotating base 231, and scale marks 2311 are also provided on the rotating base 231; wherein, the locking mechanism 220 passes through the guiding chute 2310 to be connected with the first base 210. Thus, the locking mechanism 220 can be matched with the guiding chute 2310 to realize guiding and limiting when the rotating base 231 rotates, and can be used for locking the rotating base 231 and the first base 210 through the guiding chute 2310 to limit the rotation of the rotating base 231. Meanwhile, the setting of the scale marks 2311 can be convenient for improving the adjusting speed and accuracy and improving the efficiency of positioning and clamping.
In some embodiments, two first positioning modules 200 are provided, and the structures of the two first positioning modules 200 are identical, which is not described herein. It can be appreciated that the positioning and clamping stability of the inclined beam 12 can be improved by arranging two first positioning modules 200.
Referring to fig. 2, 3 and 5, the second positioning module 300 includes a second base 310, a first adjusting mechanism 320, a second adjusting mechanism 330 and a first positioning platform 340. The second base 310 is disposed on the base 100. The first adjusting mechanism 320 is disposed on the second base 310. The second adjusting mechanism 330 is disposed on the first adjusting mechanism 320. The first positioning platform 340 is disposed on the second adjusting mechanism 330 and is used for positioning the leg support 13.
Specifically, the first positioning platform 340 is provided with a positioning boss 350, and the leg support 13 can be inserted into the positioning boss 350 for positioning. The positioning boss 350 may be optionally a positioning pin 423.
In the present embodiment, the first adjustment mechanism 320 may output a reciprocating rectilinear motion in the third direction Z, and the second adjustment mechanism 330 may output a reciprocating rectilinear motion in the first direction X. Thus, the first adjusting mechanism 320 is configured to drive the second adjusting mechanism 330 to move along the third direction Z, and the second adjusting mechanism 330 is configured to drive the first positioning platform 340 to move along the second direction Y. Therefore, under the cooperation of the first adjusting mechanism 320 and the second adjusting mechanism 330, the support leg bracket 13 can be adjusted in the first direction X and the third direction Z, so that the support leg bracket 13 is accurately positioned at a preset position, and the positioning precision and the welding quality are improved.
In some embodiments, the first and second adjustment mechanisms 320, 330 each include a lead screw drive mechanism and an adjustment drive 321, the adjustment drive 321 being in driving connection with a drive lead screw in the lead screw drive mechanism. Alternatively, the adjustment drive 321 may be selected as a hand wheel, a motor, or a motor.
In other embodiments, the first adjustment mechanism 320 and the second adjustment mechanism 330 each comprise an oil cylinder, an air cylinder, an electric push rod, an electric cylinder, and the like. It is to be understood that the foregoing is illustrative only and is not to be construed as limiting the scope of the present application.

The two turnover positioning mechanisms 420 are aligned along the first direction X on the third base 410, and the turnover positioning mechanisms 420 are used for adjusting the relative angles of the engine bracket 14 and the side wall of the longitudinal beam 11.
Specifically, the flip positioning mechanism 420 includes a flip seat 421 and a second positioning platform 422. The turnover seat 421 is disposed on the third base 410. The second positioning platform 422 is pivotally disposed on the turnover seat 421 through a pivot shaft, and a positioning pin 423 for positioning the engine support 14 is disposed on the second positioning platform 422, where an axis of the second positioning platform 422 that pivots relative to the turnover seat 421 is parallel to the second direction Y. In this manner, the engine support 14 may be placed on the second positioning platform 422 and the engine support 14 may be positioned by the positioning pins 423 on the second positioning platform 422. The relative angle of the engine bracket 14 to the side wall of the stringer 11 is then adjusted by rotating the second positioning platform 422.
Referring to fig. 2, 3 and 7, the fourth positioning module 500 further includes a fourth base 510 disposed on the base 100. The centering driving mechanism 520 includes a centering driving member 521 and a threaded screw (not shown) disposed on the fourth base 510 along the first direction X and rotatably engaged with the fourth base 510, and the centering driving member 521 is drivingly connected to an end of the threaded screw extending outside the fourth base 510 for driving the threaded screw to rotate.
Alternatively, the centering driver 521 may be a hand wheel, a motor, or the like. It is to be understood that the foregoing is illustrative only and is not to be construed as limiting the scope of the present application.
