Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of radiator manufacturing, in particular to a split type support rod applied to FSW. BACKGROUND

[0002] With the development of science and technology, the technology of FSW is more and more mature, and FSW is friction stir welding, which can ensure the dimensional accuracy and geometric accuracy of the welded part, and is gradually applied to many scenes, such as aerospace, automobile body, parts, battery arrangement, railway bridge, electronic connection and other fields. The friction welding machine is actually equivalent to a lathe with a pressing mechanism, and according to the design and manufacturing technology of modern machine tools, it is not difficult to make it have sufficient accuracy and rigidity. In addition, by using appropriate control method, the length error of the welded part after welding can be less than ±0.2mm, and the eccentricity can be within 0.2mm. Due to these technical advantages, this technology is widely used in new energy vehicles at present.

[0003] The existing uniform plate is generally made by FSW technology, and the cover plate is combined with the shell by friction welding. Due to the action of pressure, the position of the water inlet and outlet nozzle needs to be placed with a support rod, so that the position of the water inlet and outlet nozzle will not be deformed, but the existing support rod is of integral structure, and after friction welding in actual use, the integral support rod is combined with the corresponding water inlet and outlet nozzle of the shell, which is not easy to take out, and the integral support rod can be reliably taken out by borrowing external machine tools. In the sample trial stage, an integral support rod needs to be configured with machine tools, which has too high machine tool cost and needs to train operators to operate, thereby consuming a large amount of time cost and equipment cost. Therefore, it is urgent to develop a support rod which is convenient to take out, so as to save the production cost of products. UTILITY MODEL CONTENTS

[0004] In view of the above problems, the utility model provides a split type support rod applied to FSW, which makes the taking out of the support rod quick and convenient, and saves the production cost.

[0005] A split type support rod applied to FSW is suitable for filling operation of water inlet and outlet nozzle of uniform plate, characterized in that it comprises:

[0006] An upper limiting rod comprises a bottom surface and an upper arc surface, the upper arc surface is set in the same shape as the arc of the cylindrical inner wall of the water inlet and outlet nozzle, and the bottom surface and the upper arc surface form a closed surface domain;

[0007] A middle reinforcing block comprises an upper surface, a lower surface and two side surfaces, and the two side surfaces are vertical planes;

[0008] The lower limiting rod comprises a top surface and a lower arc surface, the lower arc surface is shaped according to the curvature of the inner cylindrical wall of the water inlet / outlet nozzle, and the top surface and the lower arc surface form a closed surface area.

[0009] and the limiting rod;

[0010] The upper limiting rod is provided with a first positioning hole penetrating in the thickness direction at a position in the length direction, the intermediate reinforcing block is provided with a second positioning hole penetrating in the thickness direction at a position in the length direction, and the lower limiting rod is provided with a third positioning hole penetrating in the thickness direction at a position in the length direction. The limiting rod sequentially penetrates the first positioning hole, the second positioning hole and the third positioning hole, the bottom surface of the upper limiting rod is press-fitted to the upper surface of the intermediate reinforcing block, the lower surface of the intermediate reinforcing block is press-fitted to the top surface of the lower limiting rod, and the upper limiting rod, the intermediate reinforcing block and the lower limiting rod form an integrated supporting rod through the limiting rod, which is inserted into the inner cavity of the water inlet / outlet nozzle, and the limiting rod is located at the outer end of the water inlet / outlet nozzle to perform limiting operation.

[0011] After the integrated supporting rod is inserted into position, the upper arc surface is tightly attached to the top area of the hole wall of the water inlet / outlet nozzle, the lower arc surface is tightly attached to the bottom area of the hole wall of the water inlet / outlet nozzle, and the two side vertical surfaces of the intermediate reinforcing block leave a gap with the corresponding side hole wall of the water inlet / outlet nozzle.

[0012] Further features include:

[0013] The upper limiting rod and the lower limiting rod have the same length.

[0014] The upper limiting rod and the lower limiting rod are the same limiting rod, which ensures convenient structure manufacturing.

[0015] The length of the intermediate reinforcing block is greater than that of the upper limiting rod and the lower limiting rod, and after the integrated supporting rod is inserted into position, the outer end of the intermediate reinforcing block protrudes outwardly beyond the outer end surface of the upper limiting rod and the lower limiting rod. After the limiting rod is detached, the intermediate reinforcing block can be quickly pulled out of the water inlet / outlet nozzle, and then the upper limiting rod and the lower limiting rod can be quickly detached from the water inlet / outlet nozzle.

[0016] The limiting rod is an L-shaped limiting rod, which comprises a horizontal holding end and a vertical insertion end. When the integrated supporting rod is inserted, the horizontal holding end is located at the upper end, the vertical insertion end sequentially penetrates the first positioning hole, the second positioning hole and the third positioning hole to perform insertion operation, and the insertion depth is limited by the upper protrusion and the lower protrusion of the vertical insertion end. The inner wall of the vertical insertion end stops inserting after being attached to the surface of the water inlet / outlet nozzle, thereby completing insertion positioning.

[0017] After the technology is applied, the water inlet and outlet nozzle is hollow, and the nozzle collapses due to the constant pressure in the FSW process, which affects the appearance and performance of the product, when starting FSW, the upper support rod, the middle reinforcing block and the lower support rod F are assembled, and are limited by the limiting rod, so that the water inlet and outlet nozzle does not collapse due to vibration during FSW, and the water inlet and outlet nozzle does not collapse due to the effect of the split type support rod during friction welding, after friction welding, the limiting rod is taken out first, then the middle reinforcing block is taken out, and then the upper support rod and the lower support rod are taken out, so that the auxiliary production demand is met, the support rod is taken out quickly and conveniently, and the manufacturing cost is saved.

[0029] After the integrated support rod is inserted into place, the upper arc surface 12 is tightly attached to the top area of the hole wall of the water inlet / outlet nozzle 101, the lower arc surface 32 is tightly attached to the bottom area of the hole wall of the water inlet / outlet nozzle 101, and the two side surfaces 23 of the middle reinforcing block 20 leave a gap with the corresponding side hole walls of the water inlet / outlet nozzle 101, the gap facilitates reliable pulling operation of the middle reinforcing block 20, and since the pressure is applied upward and downward, the left and right gaps do not affect the overall shape of the water inlet / outlet nozzle 101.

[0030] In specific implementation, the upper limiting rod 10 and the lower limiting rod 30 are the same limiting rod, only the angles are different, which ensures convenient structure manufacturing;

[0031] The length of the middle reinforcing block 20 is greater than that of the upper limiting rod 10 and the lower limiting rod 30, after the integrated support rod is inserted into place, the outer end of the middle reinforcing block 20 protrudes outwardly beyond the outer end surface of the upper limiting rod 10 and the lower limiting rod 30, which ensures that after the limiting rod 40 is detached, the middle reinforcing block 20 can be quickly pulled away from the water inlet / outlet nozzle 101, and then the upper limiting rod 10 and the lower limiting rod 30 can be quickly detached from the water inlet / outlet nozzle;

[0033] Its working principle is as follows: the water inlet and outlet nozzle is hollow, and the nozzle collapses under the constant pressure in the FSW process, affecting the appearance and performance of the product. When starting FSW, the upper support rod, middle reinforcing block and lower support rod F are assembled and positioned by the limiting rod to prevent the water inlet and outlet nozzle from collapsing due to vibration during FSW. During friction welding, the water inlet and outlet nozzle will not collapse due to the effect of the split support rod. After friction welding, the limiting rod is removed first, then the middle reinforcing block is removed, and finally the upper and lower support rods are removed, meeting the auxiliary production requirements. It makes the removal of the support rod quick and convenient, and saves the manufacturing cost.
