[0035] Reference Figures 1 to 4 A positioning fixture for a pipe beam structure according to an embodiment of the present invention includes a base 100 and a first positioning structure 110, a second positioning structure 120, a third positioning structure 130, and a fourth positioning structure 140 disposed on the base 100. A first clamping structure 111, a second clamping structure 120, a third clamping structure 130, and a fourth clamping structure 140 are installed on the base 100. The first positioning structure 110 is used to pre-position the front side column 410, and the first clamping structure 111 presses the front side column 410 against the first positioning structure 120, a second clamping structure 130, and a fourth clamping structure 140. A first positioning structure 110; a second positioning structure 120 for pre-positioning the rear side column 420, and a second pressing structure 121 pressing the rear side column 420 against the second positioning structure 120; a third positioning structure 130 for pre-positioning the upper reinforcing beam 430, and a third pressing structure pressing the upper reinforcing beam 430 against the third positioning structure 130; a fourth positioning structure 140 for pre-positioning the lower reinforcing beam 440, and a fourth pressing structure 141 pressing the lower reinforcing beam 440 against the fourth positioning structure 140.
[0036] Furthermore, refer to Figure 1 , Figure 3 As shown, multiple first positioning structures 110 are spaced apart along the length of the front side pillar 410, and the front side pillar 410 is provided at both ends of the length direction. Specifically, in this embodiment, there are four first positioning structures 110. Two first positioning structures 110 are respectively located at both ends of the length direction of the front side pillar 410, and two first positioning structures 110 are spaced apart at the middle of the front side pillar 410. Along the length direction of the front side pillar 410, the two first positioning structures 110 located at the middle of the front side pillar 410 are respectively located on both sides of the lower reinforcing beam 440, and the two first positioning structures 110 located at the middle of the front side pillar 410 are both located on the side of the front side pillar 410 near the rear side pillar 420.
[0037] Reference Figure 1 , Figure 3 As shown, multiple second positioning structures 120 are spaced apart along the length of the side rear column 420, and the second positioning structures 120 are provided at both ends of the length of the side rear column 420. Specifically, in this embodiment, four second positioning structures 120 are provided, with two second positioning structures 120 respectively located at both ends of the length of the side rear column 420, and two second positioning structures 120 spaced apart at the middle of the side rear column 420. A bend is provided at the middle of the side rear column 420, and two second positioning structures 120 located at the middle of the side rear column 420 are respectively located at both ends of the bend.
[0038] In embodiments of this application, multiple first clamping structures 111 are provided, and the multiple first clamping structures 111 respectively clamp the ends and middle parts of the side front uprights 410 to the first positioning structure 110. For example, refer to... Figure 1 , Figure 3 As shown, there are three first clamping structures 111, which are respectively disposed at both ends and the middle of the front side pillar 410. Correspondingly, there are multiple second clamping structures 121 in this embodiment. The multiple second clamping structures 121 respectively clamp the ends and the middle of the rear side pillar 420 to the second positioning structure 120. For example, the axial length of the rear side pillar 420 is less than the length of the front side pillar 410, so there are only two second clamping structures 121, which are respectively disposed at both ends of the rear side pillar 420.
[0039] In the embodiments of this application, reference is made to Figure 1 , Figure 3As shown, one or more third positioning structures 130 can be set according to parameters such as the length and height of the upper reinforcing beam 430. Similarly, one or more fourth positioning structures 140 can be set according to parameters such as the length and height of the lower reinforcing beam 440. Preferably, multiple third positioning structures 130 and multiple fourth positioning structures 140 are provided. Multiple third positioning structures 130 are spaced apart along the axis of the upper reinforcing beam 430, and multiple fourth positioning structures 140 are spaced apart along the axis of the lower reinforcing beam 440.
[0040] It should be noted that the vertical heights of the multiple first positioning structures 110 can be set to be equal or unequal according to actual conditions, and are not limited in this embodiment. Similarly, the vertical heights of the multiple second positioning structures 120, multiple third positioning structures 130, and multiple fourth positioning structures 140 can all be set to be equal or unequal according to actual conditions.
[0041] In the embodiments of this application, reference is made to Figure 1 , Figure 3 As shown, the third clamping structure is located in the middle of the upper reinforcing beam 430, and / or the fourth clamping structure 141 is located in the middle of the lower reinforcing beam 440; preferably, the third clamping structure is located in the middle of the upper reinforcing beam 430 and the fourth clamping structure 141 is located in the middle of the lower reinforcing beam 440; since the lengths of the upper reinforcing beam 430 and the lower reinforcing beam 440 are limited, only one first clamping structure 111 and one second clamping structure 121 need to be provided, but multiple third clamping structures or multiple fourth clamping structures 141 can also be provided according to the actual situation.
[0042] The tube beam structure positioning fixture in this embodiment of the application further includes a first limiting structure 200, which is installed on the base 100 and abuts against the side front column 410. The first limiting structure 200 is located at the connection between the side front column 410 and the upper reinforcing beam 430. Specifically, refer to... Figure 3 , Figure 4 As shown, the first limiting structure 200 is disposed on the side of the front pillar 410 of the side wall away from the rear pillar 420 of the side wall. The first limiting structure 200 includes a telescopic member 210 and a clamping member 220. The clamping member 220 is installed on the movable end of the telescopic member 210. The clamping member 220 includes two clamping pieces 221 disposed at intervals. The clamping pieces 221 are provided with slots for the front pillar 410 of the side wall to be inserted.
[0043] The tube beam structure positioning fixture in this embodiment of the application further includes a second limiting structure. The second limiting structure is installed on the base 100 and abuts against the side rear column 420. The second limiting structure is located at the connection between the side rear column 420 and the lower reinforcing beam 440. Specifically, refer to... Figure 3 , Figure 4As shown, the side rear pillar 420 has radially protruding fins 421, and the base 100 has a base 150. A second limiting structure presses the fins 421 against the base 150. The fins 421 form grooves, and the base 150 is embedded in the grooves, thereby pressing the fins 421 against the base 150. The base 150 and the fourth limiting structure cooperate to simultaneously restrict the axial sliding and circumferential rotation of the side rear pillar 420, thereby accurately positioning the connection between the side rear pillar 420 and the lower reinforcing beam 440.
[0044] It should be noted that, referring to Figure 2 As shown, the side rear pillar 420 of this embodiment includes two spaced-apart fins 421, therefore, the second limiting structure has two corresponding fins 421. In actual production, the number of the second limiting structures can be flexibly arranged according to the number of fins 421, and is not limited in this embodiment; if the number of fins 421 is large, the number of the second limiting structures can also be set to be less than the number of fins 421.
[0045] The tube beam structure positioning fixture of this application further includes a first clamping structure 160 and a second clamping structure 170. The first clamping structure 160 abuts against the front side column 410, and the second clamping structure 170 abuts against the rear side column 420. For example, refer to... Figure 1 , Figure 3 As shown, this embodiment has two first clamping structures 160. Both first clamping structures 160 are located in the middle of the front side column 410 and are located on the side of the front side column 410 near the rear side column 420. The first clamping structure 160 is used to press and push the front side column 410 against the rear side column 420, so that the front side column 410 undergoes partial elastic deformation to facilitate welding between the front side column 410 and the lower reinforcing beam 440. As can be seen from the above, the axial length of the rear side column 420 in this embodiment is less than the length of the front side column 410. Therefore, only one second clamping structure 170 is provided. The second clamping structure 170 is located on the side of the rear side column 420 near the front side column 410 and is used to push the rear side column 420 to undergo elastic deformation in the direction away from the front side column 410, so as to facilitate welding between the rear side column 420 and the lower reinforcing beam 440.
[0046] It is conceivable that the first clamping structure 160 and the second clamping structure 170 can be set in appropriate quantities according to actual conditions. Moreover, the first clamping structure 160 and the second clamping structure 170 are preferably driven by hydraulic cylinders. Compared with the conventional clamping structure driven by pneumatic cylinders, the first clamping structure 160 and the second clamping structure 170 driven by hydraulic cylinders have greater clamping force and better stability, and can achieve more precise control and positioning of the front side column 410 and the rear side column 420. In addition, hydraulic cylinders usually have a self-locking function. When the hydraulic system stops working, the hydraulic cylinder can remain in the same position, thereby keeping the first clamping structure 160 and the second clamping structure 170 in the current position and avoiding changes in the position of the front side column 410 and the rear side column 420.
[0047] The tube beam structure positioning fixture of this application further includes a first guide structure 180, which abuts against the end of the front side column 410 and pre-positions the front side column 410 along its length; and / or, the tube beam structure positioning fixture further includes a second guide structure 190, which abuts against the end of the rear side column 420 and pre-positions the rear side column 420 along its length. Specifically, refer to... Figure 1 , Figure 3 As shown, the preferred base 100 is equipped with both a first guide structure 180 and a second guide structure 190 to improve positioning efficiency.
[0048] The pipe beam structure positioning fixture of this application embodiment uses a first positioning structure 110, a second positioning structure 120, a third positioning structure 130, and a fourth positioning structure 140 to pre-position the front side column 410, the rear side column 420, the upper reinforcing beam 430, and the lower reinforcing beam 440, respectively. Then, the first clamping structure 111, the second clamping structure 121, the third clamping structure 130, and the fourth clamping structure 141 respectively press the front side column 410, the rear side column 420, the upper reinforcing beam 430, and the lower reinforcing beam 440 against the first positioning structure 110, the second positioning structure 120, the third clamping structure 130, and the fourth clamping structure 141. 20. The third positioning structure 130 and the fourth positioning structure 140 provide good limiting effect. The first limiting structure 200, in conjunction with the first pressing structure 111 and the fourth pressing structure 141, improves the positioning accuracy at the connection between the lower reinforcing beam 440 and the front side column 410. The second limiting structure, in conjunction with the second pressing structure 121 and the fourth pressing structure 141, improves the positioning accuracy at the connection between the lower reinforcing beam 440 and the rear side column 420. All of the above positioning structures, pressing structures, limiting structures and guiding structures are mechanical structures, which are simple in structure and have good environmental adaptability.
