[0002] The front floor longitudinal beam is an important component in the automobile body structure. It is usually located under the front floor of the automobile and is arranged longitudinally along the vehicle body. The front floor longitudinal beam plays a role in bearing and supporting the vehicle body, and can bear the vehicle body weight and the acting forces from roads and other aspects. When the vehicle collides, the front floor longitudinal beam can also collapse to absorb energy to reduce the impact on the vehicle occupants, which has an important impact on the safety of the vehicle. When processing the front floor longitudinal beam, projection welding is usually required.
[0003] A projection welder is a welding equipment that adopts the projection welding process. Projection welding is a deformation of spot welding. Its working principle is to pre-process one or more projection points on the joint surface of a workpiece, make it contact with the surface of another workpiece and conduct electricity for heating, and then collapse to form welding spots at these contact points.
[0004] However, in the above-mentioned manner, when the existing projection welding equipment processes workpieces, most of them still manually load projection welding nuts and manually hold the position state of the workpiece during processing. Therefore, when performing projection welding on multiple projection welding nuts of the same workpiece, the operator not only needs to continuously adjust the processing position of the workpiece but also needs to install the projection welding nuts after adjusting the workpiece position, resulting in more trouble during actual operation and lower overall processing efficiency. Summary of the Utility Model

The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.
[0021] The first embodiment of the present application is as follows:
[0022] Please refer to Figure 1 and Figure 2 wherein Figure 1 is a schematic structural diagram of the overall projection welding equipment for the front floor longitudinal beam, Figure 2 is a schematic structural diagram of the opened material rack 106.
[0023] The utility model provides a projection welding device for a front floor longitudinal beam, which comprises a frame 101, a working main body 102, a placing table 103 and a feeding assembly.

The pushing member includes a pushing block 111, a driving toothed belt 112 and a driving member. The driving member includes a driving gear 113 and a driving motor 114. Through the foregoing solution, when processing workpieces with existing projection welding devices, most of them still use manual labor to load projection welding nuts and manually hold the workpieces to stabilize their position states during processing. Therefore, when performing projection welding on multiple projection welding nuts on the same workpiece, the operator not only needs to continuously adjust the processing position of the workpiece but also install the projection welding nuts after adjusting the workpiece position, resulting in cumbersome actual operation and low overall processing efficiency.
[0024] In this embodiment, the working main body 102 is installed on the frame 101, the placing table 103 is fixedly installed on the frame 101, the working main body 102 is an existing mechanism body for projection welding, and the working main body 102 is mainly composed of a projection welder and a driving mechanism for driving the projection welder to work up and down, so as to perform projection welding on the workpiece placed on the placing table 103 through the provided working main body 102.
[0025] Among them, the fixing plate 104 is fixedly connected to the frame 101 and is located on one side of the frame 101. The lifting bracket 105 is slidably connected to the fixing plate 104 and is located on one side of the fixing plate 104. The material placing rack 106 is connected to the lifting bracket 105 through the adjusting member and is located on one side of the lifting bracket 105. The adjusting member is connected to the lifting bracket 105, the pushing member is connected to the material placing rack 106, and the positioning member is connected to the placing table 103. The fixing plate 104 is fixed on the frame 101, and the lifting bracket 105 is slidably arranged on the fixing plate 104 through two guide posts provided at the top. The material placing rack 106 is arranged on the side of the lifting bracket 105. The material placing rack 106 is composed of a storage cylinder on the side and a guide box body at the bottom. Users can stack multiple projection welding nuts in the storage cylinder, and then push the bottom projection welding nut through the pushing member provided on the material placing rack 106. The projection welding nut pushed to the limit position can be exported through the discharge slot provided on the side of the material placing rack 106. Then, under the action of gravity, when the bottom projection welding nut is pushed, the upper nut will automatically descend, thus completing the automatic continuous feeding of the projection welding nuts.
[0026] Secondly, the output end of the lifting cylinder 107 is connected to the lifting bracket 105, and the lifting cylinder 107 is fixedly installed on the fixed plate 104; the moving bracket 108 is fixedly connected to the feeding rack 106 and is slidably installed on one side of the lifting bracket 105; the moving screw 109 is threadedly connected to the moving bracket 108 and is rotatably installed on one side of the lifting bracket 105; the output shaft of the moving motor 110 is connected to the moving screw 109, and the moving motor 110 is fixedly installed on one side of the lifting bracket 105. The output end of the lifting cylinder 107 is fixed to the lifting bracket 105. The moving bracket 108 fixed to the side of the feeding rack 106 is slidably arranged on the lifting bracket 105. The threaded hole provided on the moving bracket 108 is adapted to the external thread of the moving screw 109. The moving screw 109 is fixed to the output shaft of the moving motor 110. When the moving motor 110 drives the moving screw 109 to rotate, the moving screw 109 will drive the moving bracket 108 to drive the feeding rack 106, so as to flexibly adjust the matching height and matching position of the feeding rack 106 through the corresponding driving of the lifting bracket 105 and the moving bracket 108.
[0027] Meanwhile, the pushing block 111 is slidably connected to the feeding rack 106 and is located on one side of the feeding rack 106; the driving toothed belt 112 is fixedly connected to the pushing block 111 and is located on one side of the pushing block 111; the driving member is connected to the feeding rack 106.

The pushing block 111 is slidably arranged in the feeding rack 106. The driving toothed belt 112 is fixedly arranged on the top of the feeding rack 106. The driving gear 113 cooperates with the driving gear 113. The driving gear 113 is fixed to the output shaft of the driving motor 114, enabling the user to drive the driving gear 113 to rotate through the driving motor 114, and then drive the driving toothed belt 112 and the pushing block 111 to move through the rotation of the driving gear 113, so as to complete the automatic feeding of the projection welding nuts inside the feeding rack 106 through the driving of the pushing block 111.
[0028] When a front floor longitudinal beam projection welding device of this embodiment is used, a plurality of projection welding nuts are stacked and placed through the storage barrel provided on the material rack 106, and then the matching height of the material rack 106 is adjusted by the lifting cylinder 107 according to the actual size of the workpiece to be processed. After the workpiece is placed and fixed, the moving motor 110 can drive the moving bracket 108 and the material rack 106 by driving the moving screw 109, so that the lead-out hole on the bottom side of the material rack 106 corresponds to the processing position of the workpiece, and then the driving motor 114 is used to cooperate with the driving screw 109 to drive the moving bracket 108 and the material rack 106. The gear 113 and the toothed belt 112 move the ejection block 111. With the movement of the ejection block 111, the projection welding nut inside the discharge rack 106 can cooperate with the workpiece through the lead-out hole on the bottom side of the discharge rack 106. Finally, the moving motor 110 cooperates with the moving screw 109 to drive the moving bracket 108 and the discharge rack 106 to move out, so that the working body 102 can subsequently process the completed projection welding nuts and workpieces, thereby realizing the automatic feeding of the completed projection welding nuts through the provided components, making it more convenient and quick for operators to operate in actual operation.
[0029] Second embodiment:
[0030] See also Figures 3 to 5 , Figure 3 This is a schematic diagram of the overall structure of the front floor longitudinal beam projection welding equipment of the second embodiment. Figure 4 This is a schematic structural diagram of a cutaway placement platform 103 according to the second embodiment. Figure 5 This is a structural diagram of the second embodiment with the positioning column 203 and the embedded block 204 removed. The positioning component provided by the present utility model includes a mounting plate 201, a lifting cylinder 202, a positioning column 203 and an embedded block 204.
[0031] Among them, the mounting disc 201 is slidably connected to the placement table 103 and is located on one side of the placement table 103; the output end of the lifting cylinder 202 is connected to the mounting disc 201, and the lifting cylinder 202 is fixedly installed on one side of the placement table 103; the positioning column 203 is threadedly connected to the mounting disc 201 and is located on one side of the mounting disc 201; the embedding block 204 is connected to the placement table 103 and is located on one side of the placement table 103 close to the positioning column 203. The mounting disc 201 is slidably arranged in the placement table 103. An installation screw is provided on the top of the mounting disc 201, and the threaded hole provided at the bottom of the positioning column 203 is adapted to the installation screw on the top of the mounting disc 201, so that the user can complete the installation and fixation through the cooperation of the positioning column 203 and the installation screw on the top of the mounting disc 201. A corresponding hexagonal socket is also provided at the top of the positioning column 203, which is convenient for the user to fix the positioning column 203 and for subsequent disassembly and replacement. The output end of the lifting cylinder 202 is fixed to the mounting disc 201, so that the user can directly drive the mounting disc 201 and the positioning column 203 mounted on the mounting disc 201 through the lifting cylinder 202. An installation groove for installing the embedding block 204 is provided on the surface of the placement table 103 where the positioning column 203 is provided. The embedding block 204 is provided with a through hole having the same shape and size as the positioning column 203. At the same time, a clamping table is provided on the side of the bottom end of the positioning column 203, and a clamping groove for matching with the clamping table at the bottom of the positioning column 203 is also provided at the bottom of the embedding block 204. When the user needs to replace the positioning column 203 with different diameters, the embedding block 204 can be disassembled together when the positioning column 203 removed from the mounting disc 201 is pulled out. The positioning column 203 and the embedding block 204 are used in pairs. When replacing the positioning column 203 with different diameters, the embedding block 204 with a corresponding size through hole also needs to be replaced, so as to facilitate the auxiliary positioning of the processing position of the workpiece to be processed and the nut fed from the material rack 106 through the provided positioning column 203.
[0032] When using a projection welding device for the front floor longitudinal beam of this embodiment, the positioning column 203 can be used to position the processing position of the workpiece to be processed in advance, and at the same time, it can also help quickly position the nuts exported on the material rack 106. When performing projection welding operations and adjusting the workpiece processing position after the operation, the lifting cylinder 202 can drive the mounting plate 201 and the positioning column 203 to move downward, enabling the workpiece to directly translate on the placement table 103, facilitating the user to adjust the processing position of the workpiece. When the user needs to process workpieces of different types and sizes, better positioning cooperation can be achieved by replacing the positioning columns 203 and the embedding blocks 204 of different sizes. The embedding block 204 is mainly set to ensure that when the size of the positioning column 203 needs to be adjusted, the cooperation between the positioning column 203 and the tabletop of the placement table 103 will not be affected. Otherwise, if the embedding block 204 is not used, when replacing the positioning column 203 with a large size difference, a large gap will appear at the position where the positioning column 203 cooperates with the placement table 103, thus affecting subsequent normal processing.
[0033] The above-disclosed are only one or more preferred embodiments of the present application, and the scope of rights of the present application cannot be limited thereby. Those of ordinary skill in the art can understand the entire or partial processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
