Description

Technical Field

[0001] This utility model relates to the field of stainless steel plate welding, specifically to a fixing frame for welding stainless steel plates. Background Technology

[0002] Stainless steel plate welding refers to the process of permanently joining two or more stainless steel plates by heating, pressurizing, or a combination of both to create atomic bonds in localized areas. Special stainless steel welding materials must be used during welding, and measures must be taken to prevent the corrosion resistance and mechanical properties of the stainless steel from decreasing due to the heat effect of welding. Stainless steel plate welding is a widely used technology in industrial manufacturing, and its quality directly affects the corrosion resistance, strength, and appearance of the product. During welding, a fixing frame is needed to secure the two steel plates to ensure welding stability.

[0003] A search revealed a utility model patent with publication number CN207139082U, which discloses a fixing device for welding stainless steel plates. The device includes an operating table with fixing clamps connected to the top left and right sides of the operating table via screws. Each fixing clamp includes a base plate with mounting plates connected to its front and rear sides. The mounting plates are bolted to the top of the operating table. The top of the base plate has a sliding groove with a slider embedded within it. Two rows of limiting holes are evenly distributed on the base plate, located on opposite sides of the sliding groove. The slider is connected to the limiting holes via limiting screws. A movable clamping plate is welded to the top of the slider. This fixing device for welding stainless steel plates, with its adjustable size design, is suitable for cutting different types of stainless steel plates, increasing its application range. The weld scale receiving groove facilitates the treatment of oxide scale generated during the welding process.

[0004] In the existing stainless steel plate welding process, the stainless steel plates on both sides are fixed and then welded at the joint. However, the existing fixing devices are generally used for horizontal welding. But stainless steel plates need to be welded at a 90-degree angle during the welding process. And due to the elasticity of stainless steel plates, even hand-held welding cannot guarantee the stability of the welding, thus affecting the normal processing of the welding.

[0005] Therefore, it is necessary to invent a fixing frame for welding stainless steel plates to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a fixing frame for welding stainless steel plates. By moving two sets of movable seats in different directions, it is possible to fix the seams of stainless steel plates for right-angle welding and flat welding, thereby solving the problem that welding fixing devices in the prior art cannot perform right-angle welding.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fixing frame for welding stainless steel plates, including a fixing platform, with movable seats symmetrically arranged above the fixing platform;

[0008] The horizontal fixing component above the movable seat includes a push plate. The push plate is positioned above the movable seat. Bolts are symmetrically screwed on both sides of the upper part of the push plate, and the two sets of bolts are rotatably connected to the upper part of the movable seat. Slide rods are sequentially limited and connected inside the push plate. A fixing plate is installed below each set of slide rods. A spring is sleeved on each set of slide rods, and the two ends of the spring are respectively attached to the fixing plate and the push plate.

[0009] The right-angle fixing assembly installed above the fixed platform includes an L-shaped connecting plate. The L-shaped connecting plate is symmetrically installed on both sides above the fixed platform. A baffle is provided on one side of the L-shaped connecting plate, and there is a gap between the baffle and the bottom of the L-shaped connecting plate. The height of the gap is opposite to that of the movable seat and is at the same horizontal position. A U-shaped connecting frame is installed between the L-shaped connecting plate and the baffle.

[0010] Preferably, the horizontal fixing assembly further includes a support plate, which is symmetrically installed above the fixing plate. An internal thread block is installed below the movable seat, and guide blocks are installed on both sides of the internal thread block below the movable seat.

[0011] Preferably, a connecting groove is provided above the fixed platform, and a bidirectional screw is rotatably connected in the connecting groove. The bidirectional screw is screwed to an internal thread block. A hexagonal knob is axially connected to one side of the bidirectional screw, and the hexagonal knob is located on one side of the fixed platform.

[0012] Preferably, two sets of guide grooves are symmetrically arranged above the fixed platform, and the guide grooves are slidably connected to the corresponding guide blocks. A bearing platform is installed at the center position above the fixed platform, and the bearing platform and the movable seat are at the same horizontal position.

[0013] Preferably, the right-angle fixing assembly further includes a push rod, which is sequentially connected through the baffle. A fixing plate two is installed on the side of the push rod near the L-shaped connecting plate, and a synchronization plate is installed on the side of the push rod away from the fixing plate two. A spring two is sleeved on the push rod, and the two ends of the spring two are respectively attached to the synchronization plate and the baffle.

[0014] Preferably, a connecting frame is installed on one side above the fixing plate, and a pressing block is slidably connected inside the connecting frame. The pressing block and the synchronization plate are arranged opposite to each other. A guide rod is installed on the inner wall of the connecting frame, and the guide rod is sleeved with the pressing block. A spring is sleeved on the guide rod, and the two ends of the spring are respectively attached to the inner wall of the connecting frame and the pressing block.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] By fixing two sets of stainless steel plates on adjacent sides of the movable base, the two sets of movable bases are driven to move closer together, thus completing the planar welding seam fixing of the stainless steel plates. Alternatively, by fixing one set of stainless steel plates in the opposite position of the movable base and inserting the other set of stainless steel plates between the L-shaped connecting plate and the baffle, and driving the movable base to move closer to the L-shaped connecting plate, the right-angle welding seam fixing of the stainless steel plates can be completed. This structure can achieve both planar welding seam fixing and right-angle welding seam fixing during stainless steel plate welding. It also ensures the accuracy of the seam fixing while utilizing its own moving force, thereby meeting the requirements of stainless steel plate welding and improving the welding quality.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-6 The stainless steel plate welding fixture shown includes a fixed platform 001, and movable seats 101 are symmetrically arranged above the fixed platform 001.

[0028] The horizontal fixing component 002 located above the movable seat 101 includes a push plate 201. The push plate 201 is located above the movable seat 101. Bolts 202 are symmetrically screwed on both sides of the upper part of the push plate 201, and the two sets of bolts 202 are rotatably connected to the upper part of the movable seat 101. Slide rods 203 are sequentially limited and connected inside the push plate 201. A fixing plate 204 is installed below each set of slide rods 203. A spring 205 is sleeved on each set of slide rods 203, and the two ends of the spring 205 are respectively attached to the fixing plate 204 and the push plate 201.

[0029] By placing the stainless steel plate on one side of the movable seat 101 according to the welding requirements, both hands simultaneously tighten the bolts 202, causing the bolts 202 to drive the push plate 201 to move downwards. At this time, the spring 205 presses the fixing plate 204 below, thereby causing the fixing plate 204 to press the stainless steel plate. The push plate 201 can continue to move, thus firmly fixing the stainless steel plate.

[0030] The right-angle fixing assembly 003, which is set above the fixed platform 001, includes an L-shaped connecting plate 301. The L-shaped connecting plate 301 is symmetrically installed on both sides above the fixed platform 001. A baffle 302 is provided on one side of the L-shaped connecting plate 301, and there is a gap between the baffle 302 and the bottom of the L-shaped connecting plate 301. The height of the gap is opposite to that of the movable seat 101 and is at the same horizontal position. A U-shaped connecting frame 303 is installed between the L-shaped connecting plate 301 and the baffle 302.

[0031] Through the gap between the L-shaped connecting plate 301 and the baffle 302, the movable seat 101 can drive one side of the upper stainless steel plate into the lower part of the L-shaped connecting plate 301. At this time, another set of stainless steel plates is inserted between the L-shaped connecting plate 301 and the baffle 302 to form a right-angle weld. The U-shaped connecting frame 303 can be replaced according to the size of the stainless steel plate to ensure that the stainless steel plate can smoothly enter between the L-shaped connecting plate 301 and the baffle 302.

[0032] Furthermore, in the above structure, the horizontal fixing component 002 also includes a support plate 206, which is symmetrically installed above the fixing plate 204. An internal thread block 207 is installed below the movable seat 101, and guide blocks 208 are installed on both sides of the internal thread block 207 below the movable seat 101.

[0033] With the cooperation of the bearing plate 206, the fixing plate 204 can firmly fix the stainless steel plate.

[0034] Furthermore, in the above structure, a connecting groove 209 is provided above the fixed platform 001, and a bidirectional screw 210 is rotatably connected in the connecting groove 209. The bidirectional screw 210 is screwed to the internal thread block 207. A hexagonal knob 211 is axially connected to one side of the bidirectional screw 210, and the hexagonal knob 211 is located on one side of the fixed platform 001.

[0035] By cooperating with the bidirectional screw 210 and the internal thread block 207, the moving seat 101 can move in opposite directions, so that when the stainless steel plate is fixed on the adjacent sides of the two sets of moving seats 101, it can be fixed by planar welding. When fixed on the opposite side, the moving seat 101 can be driven to move closer to the L-shaped connecting plate 301, thereby achieving right-angle welding and fixing.

[0036] Furthermore, in the above structure, two sets of guide grooves 212 are symmetrically opened above the fixed platform 001, and the guide grooves 212 are slidably connected to the corresponding guide blocks 208. A bearing platform 213 is installed at the center position above the fixed platform 001, and the bearing platform 213 and the movable seat 101 are at the same horizontal position.

[0037] The cooperation between the guide groove 212 and the guide block 208 ensures the stable operation of the movable seat 101 while also guaranteeing the accuracy of the seam alignment.

[0038] Furthermore, in the above structure, the right-angle fixing component 003 also includes a push rod 304, which is sequentially connected through the baffle 302. A fixing plate 305 is installed on the side of the push rod 304 near the L-shaped connecting plate 301, and a synchronization plate 306 is installed on the side of the push rod 304 away from the fixing plate 305. A spring 307 is sleeved on the push rod 304, and the two ends of the spring 307 are respectively attached to the synchronization plate 306 and the baffle 302.

[0039] Through the cooperation of the synchronization plate 306 and the second spring 307, the push rod 304 drives the second fixing plate 305 to fit against one side of the baffle 302, thereby ensuring that the stainless steel plate can enter between the baffle 302 and the L-shaped connecting plate 301.

[0040] Furthermore, in the above structure, a connecting frame 308 is installed on one side above the fixing plate 204. A pressing block 309 is slidably connected inside the connecting frame 308, and the pressing block 309 is arranged opposite to the synchronous plate 306. A guide rod 310 is installed on the inner wall of the connecting frame 308, and the guide rod 310 is sleeved with the pressing block 309. A spring 311 is sleeved on the guide rod 310, and the two ends of the spring 311 are respectively attached to the inner wall of the connecting frame 308 and the pressing block 309.

[0041] Spring 311 ensures that the pressing block 309 is always in an outward moving state within the connecting frame 308. When the moving seat 101 moves toward the L-shaped connecting plate 301, the pressing block 309 can be brought into contact with the synchronous plate 306. Using the force of movement, the fixing plate 305 can fix the stainless steel plate between the L-shaped connecting plate 301 and the baffle 302. Spring 311 can also prevent hard contact that could damage the components.

[0042] The working principle of this practical application is as follows:

[0043] Refer to the instruction manual appendix Figure 1-6 By placing the stainless steel plate on both sides of the two sets of movable seats 101, and then rotating the two sets of bolts 202 with both hands, the push plate 201 moves downward, thereby fixing the stainless steel plate with the fixing plate 204. Then, by rotating the double-ended screw 210 with the hexagonal knob 211, the internal thread block 207 moves the two sets of movable seats 101 closer together, thus completing the butt weld fixing of the stainless steel plate. When right-angle welding is required, simply use the same method to fix the stainless steel plate to the opposite side of the movable seat 101. Then, insert another set of steel plates between the L-shaped connecting plate 301 and the baffle 302. Then, by driving the movable seat 101... This causes one side of the stainless steel plate to move into the gap below the L-shaped connecting plate 301. At the same time, the pressing block 309 contacts the synchronous plate 306 and generates pressure as it moves continuously. This causes the fixing plate 305 to fix the steel plate between the L-shaped connecting plate 301 and the baffle 302, thus creating a right-angle seam effect. Welding can then be performed through the gap below the L-shaped connecting plate 301. This structure can achieve both planar seam fixing and right-angle welding seam fixing during stainless steel plate welding. Furthermore, by utilizing its own moving force, it can fix the plate while ensuring the accuracy of the seam, thereby meeting the requirements of stainless steel plate welding and improving the welding quality.

[0044] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
