Description

Technical Field

[0001] This utility model relates to the field of welding and fixing technology, and more specifically, to a welding and fixing device for a front wall panel. Background Technology

[0002] In the production process of the front wall panel, in order to improve the strength of the front wall panel, it is necessary to further weld a reinforcing plate on the surface of the front wall panel. During the welding process, a fixing device is usually required, such as the fixing device for welding vehicle frame fuel tank pieces (patent publication number CN216503164U), which includes a tooling support frame. An outer wall panel clamping frame is fixedly connected to the lower surface of the tooling support frame. An outer wall panel clamping seat is fixedly connected to both the lower surface of the tooling support frame located on the side of the outer wall panel clamping frame and the upper surface of the tooling support frame. A fuel tank rear wall panel positioning frame is fixedly connected to the side of the tooling support frame, and a fuel tank front wall panel positioning rod is fixedly connected to the upper surface of the tooling support frame located on the side of the outer wall panel clamping seat.

[0003] Although the aforementioned fixing device can fix the plates, in the welding process between the front wall plate and the reinforcing plate, the reinforcing plate is not located on the left or right side of the front wall plate. The reinforcing plate is small in size, its number is not fixed, and it is distributed on the front and back sides of the front wall plate. Since the welding method usually uses spot welding, spot welding space needs to be reserved at the top and bottom of the plates. This means that the aforementioned fixing device can only fix the front wall plate during welding and cannot fix the reinforcing plate.

[0004] Currently, the common practice is to first use glue to temporarily fix the front wall panel and the reinforcing plate, then use a fixing device to clamp the front wall panel, and finally spot weld them together. However, during the welding process, due to the limited strength of the glue itself, the heat, vibration and mechanical stress generated during the welding process may cause the glue's viscosity to decrease, making it unable to maintain the relative position between the front wall panel and the reinforcing plate, resulting in a decrease in welding accuracy. Utility Model Content

[0005] The main purpose of this utility model is to provide a front wall panel welding and fixing device, which can effectively solve the problem that the existing fixing device cannot simultaneously fix the front wall panel and the reinforcing plate, resulting in the welding position shifting due to the use of glue for fixing only during the welding process.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A front wall panel welding and fixing device includes a processing table, with extension tables on both sides of the processing table. Fixing components for fixing the front wall panel are provided on both sides of the upper surface of the processing table. Supporting components for supporting the welding joint are installed on both the extension tables and the upper surface of the processing table. An air pump is installed on one side of the processing table, and a PLC control cabinet is fixedly installed on the other side of the processing table.

[0008] Preferably, the fixing assembly includes four cylinders, which are respectively fixedly installed on both sides of the processing table. A fixing plate is fixedly installed on the surface of each cylinder. A limiting seat is fixedly installed on the upper end of each cylinder. A limiting connecting rod is provided on the upper end of the limiting seat. A flipping frame is rotatably installed between the cylinder output end and the limiting connecting rod. A flipping support plate is fixedly installed on one side of the flipping frame.

[0009] Preferably, solenoid valves are fixedly installed on both sides of the processing table, the air pump is connected to the two solenoid valves through a first branch pipe, an air exchange hole is provided on one side of the cylinder, and a second branch pipe is connected between adjacent air exchange holes. The second branch pipe is connected to the solenoid valve docking interface through a connecting pipe, and both the air pump and the solenoid valve are connected to the PLC control cabinet for signal connection.

[0010] Preferably, the support assembly includes two second fixed seats, which are fixedly installed on the upper surface of the processing table. The second fixed seats have a second combination slot inside, and a second combination socket is installed inside the second combination slot. A lower support plate is provided on the upper side of the second combination socket.

[0011] Preferably, the second combination socket has a second groove in the middle, the second fixing seat has a second screw hole inside, and a combination bolt is installed inside the second groove, the combination bolt being threaded into the second screw hole.

[0012] Preferably, a column is fixedly installed on the upper end of the extension platform, a limiting groove is opened inside the column, a limiting slide is slidably installed inside the limiting groove, and two first fixing seats are fixedly installed on the lower surface of the limiting slide.

[0013] A synchronous motor is fixedly installed at the upper end of the column, and a drive screw is fixedly installed at the output end of the synchronous motor. The drive screw passes through the limiting slide and is threaded together.

[0014] Preferably, a first combination slot is provided on the lower side of the first fixed base, a first combination socket is inserted and installed inside the first combination slot, an upper support plate is installed on the outside of the first combination socket, the upper support plate and the lower support plate cooperate to clamp the front wall plate and the reinforcing plate, and spot welding holes for welding are provided on both sides of the upper support plate and the lower support plate.

[0015] Preferably, the first fixing base has a first groove inside, the first combination socket has a first screw hole inside, a combination bolt is installed inside the first groove, and the lower end of the combination bolt is threaded into the first screw hole.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The synchronous motors on both sides can be started and stopped synchronously through the PLC control cabinet. During the rotation of the synchronous motor, the drive screw rotates. By utilizing the limiting cooperation between the limiting slide and the limiting slide, the height of the limiting slide is adjusted when the drive screw and the limiting slide are threaded together, so as to achieve close clamping between the upper support plate and the lower support plate. The upper support plate and the lower support plate can clamp the common position between the front wall plate and the corresponding reinforcing plate, thereby ensuring that the position between the front wall plate and the corresponding reinforcing plate will not shift during the welding process, avoiding the situation where the reinforcing plate moves during the welding process and causing welding deviation. Furthermore, the first combination slot and the second combination slot can be freely replaced to adapt to different numbers and positions of welding positions.

[0018] (2) The rotating combination bolts can be threaded to the first screw hole and the second screw hole respectively. Under this connection, the first combination socket and the second combination socket can be fixed respectively. The first combination slot and the second combination slot can be freely replaced. This avoids the welding impurities remaining on the surface of the upper support plate and the lower support plate after long-term welding, which may cause slight deviations or wear of the plates during subsequent support fixing. This ensures the accuracy and quality of each processing. The welding between the front wall plate and the reinforcing plate is usually spot welding. Spot welding holes can be used to reserve spot welding positions so that the upper and lower ends of the spot welding equipment can be positioned to ensure welding accuracy. It is also necessary to replace the corresponding upper support plate and the lower support plate to meet the spot welding connection at different positions. Attached Figure Description

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0026] like Figures 1 to 5 As shown, a front wall panel welding and fixing device includes a processing table 1, extension tables 3 are provided on both sides of the processing table 1, fixing components 2 for fixing the front wall panel are provided on both sides of the upper surface of the processing table 1, and a support component 4 for supporting the welding joint is installed on both the extension tables 3 and the upper surface of the processing table 1. An air pump 6 is installed on one side of the processing table 1, and a PLC control cabinet 5 is fixedly installed on the other side of the processing table 1.

[0027] In this embodiment, the fixing component 2 includes four cylinders 201, which are respectively fixedly installed on both sides of the processing table 1. A fixing support plate 206 is fixedly installed on the surface of the cylinder 201. A limit seat 203 is fixedly installed on the upper end of the cylinder 201. A limit connecting rod 204 is provided on the upper end of the limit seat 203. A flipping frame 202 is rotatably installed between the output end of the cylinder 201 and the limit connecting rod 204. A flipping support plate 205 is fixedly installed on one side of the flipping frame 202.

[0028] In this embodiment, solenoid valves 602 are fixedly installed on both sides of the processing table 1. The air pump 6 is connected to the two solenoid valves 602 through the first branch pipe 601. A ventilation hole 2011 is provided on one side of the cylinder 201. A second branch pipe 2012 is connected between adjacent ventilation holes 2011. The second branch pipe 2012 is connected to the interface of the solenoid valve 602 through the connecting pipe 2013. The air pump 6 and the solenoid valve 602 are both connected to the PLC control cabinet 5 for signal connection.

[0029] The PLC control cabinet 5 controls the simultaneous start and stop of two solenoid valves 602, thereby cooperating with the air pump 6 to control multiple connecting pipes 2013. Then, the second branch pipe 2012 is connected to each cylinder 201 to achieve synchronous control of multiple cylinders 201. When the output end of the cylinder 201 rises, under the action of the limit seat 203, one end of the flipping frame 202 rises and the other end falls. The falling end is the flipping support plate 205, which can cooperate with the fixed support plate 206 to fix the position of the front wall plate to prevent the front wall plate from moving during subsequent welding.

[0030] In this embodiment, the support component 4 includes two second fixed seats 407. The second fixed seats 407 are fixedly installed on the upper surface of the processing table 1. The second fixed seats 407 have a second combination slot 4072 inside. The second combination slot 4072 has a second combination socket 4075 installed inside. The lower support plate 4071 is provided on the upper side of the second combination socket 4075.

[0031] The second combination socket 4075 has a second groove 4074 in the middle, and the second fixing base 407 has a second screw hole 4073 inside. The combination bolt 408 is installed inside the second groove 4074, and the combination bolt 408 is threadedly engaged with the second screw hole 4073.

[0032] In this embodiment, a column 401 is fixedly installed on the upper end of the extension platform 3. A limiting groove 404 is opened inside the column 401. A limiting slide 405 is slidably installed inside the limiting groove 404. Two first fixing seats 406 are fixedly installed on the lower surface of the limiting slide 405.

[0033] A synchronous motor 402 is fixedly installed on the upper end of the column 401. A drive screw 403 is fixedly installed on the output end of the synchronous motor 402. The shaft of the drive screw 403 passes through the limiting slide 405 and is threaded together.

[0034] The PLC control cabinet 5 can control the synchronous motors 402 on both sides to start and stop synchronously. During the rotation of the synchronous motors 402, the drive screw 403 rotates. By utilizing the limiting cooperation between the limiting slide groove 404 and the limiting slide 405, the height of the limiting slide 405 is adjusted when the drive screw 403 is threadedly engaged with the limiting slide 405. This allows for close clamping between the upper support plate 4061 and the lower support plate 4071. The upper support plate 4061 and the lower support plate 4071 can clamp the common position between the front wall plate and the corresponding reinforcing plate, thereby ensuring that there is no positional displacement between the front wall plate and the corresponding reinforcing plate during the welding process. This avoids the situation where the reinforcing plate moves during the welding process, causing welding deviation.

[0035] In this embodiment, a first combination slot 4062 is provided on the lower side of the first fixed base 406, a first combination socket 4065 is inserted and installed inside the first combination slot 4062, an upper support plate 4061 is installed on the outside of the first combination socket 4065, the upper support plate 4061 and the lower support plate 4071 cooperate to clamp the front wall plate and the reinforcing plate, and spot welding holes 409 for welding are provided on both sides of the upper support plate 4061 and the lower support plate 4071.

[0036] The first fixed base 406 has a first groove 4064 inside, the first combination socket 4065 has a first screw hole 4063 inside, the first groove 4064 has a combination bolt 408 installed inside, and the lower end of the combination bolt 408 is threaded into the first screw hole 4063.

[0037] By rotating the combination bolt 408, it can be threadedly connected to the first screw hole 4063 and the second screw hole 4073 respectively. Under this connection, the first combination socket 4065 and the second combination socket 4075 can be fixed respectively. With the first combination slot 4062 and the second combination slot 4072, they can be freely replaced. This avoids the situation where welding impurities remain on the surface of the upper support plate 4061 and the lower support plate 4071 after long-term welding, which may cause slight deviations or wear on the plates during subsequent support fixing. This ensures the accuracy and quality of each processing. The welding between the front wall plate and the reinforcing plate is usually spot welding. The spot welding hole 409 can be used to reserve the spot welding position, so that the upper and lower ends of the spot welding equipment can be positioned to ensure welding accuracy. It is also necessary to replace the corresponding upper support plate 4061 and lower support plate 4071 to meet the spot welding connection in different positions.

[0038] Working principle of the front wall panel welding and fixing device:

[0039] In use, first apply glue to the welding area of ​​the front wall panel, then attach the reinforcing plate to the corresponding glue position. After that, place the front wall panel on top of the fixed support plate 206. After completion, control the two solenoid valves 602 simultaneously through the PLC control cabinet 5, thereby cooperating with the air pump 6 to control multiple connecting pipes 2013. Then, use the second branch pipe 2012 to connect to each cylinder 201 respectively to achieve synchronous control of multiple cylinders 201. When the output end of the cylinder 201 rises, under the action of the limit seat 203, one end of the flipping frame 202 rises and the other end falls, and the falling end is the flipping support plate 205, so that the flipping support plate 205 can cooperate with the fixed support plate 206 to fix the position of the front wall panel.

[0040] Subsequently, the motor is started, and during the rotation of the synchronous motor 402, the drive screw 403 rotates. Utilizing the limiting cooperation between the limiting slide groove 404 and the limiting slide 405, the height of the limiting slide 405 is adjusted when the drive screw 403 is threaded into the limiting slide 405. This allows for close clamping between the upper support plate 4061 and the lower support plate 4071. The upper support plate 4061 and the lower support plate 4071 can clamp the common position between the front wall panel and the corresponding reinforcing plate, thereby completing the joint fixation of the front wall panel and the reinforcing plate. Subsequently, spot welding is performed from the reserved space on both sides of this application using spot welding equipment.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
