Description

Technical Field

[0001] This utility model relates to the field of welding auxiliary fixture technology, specifically a welding auxiliary fixture for preventing zinc layer damage to galvanized welded steel parts. Background Technology

[0002] Welding auxiliary fixtures are tools used to fix, position, and support the workpiece during the welding process. Welding auxiliary fixtures can ensure that the workpiece maintains the correct position and angle during the welding process, thus ensuring the accuracy and quality of the welding.

[0003] Traditional welding auxiliary fixtures typically clamp two sets of steel vertically for welding. However, when welding steel that requires angled surfaces, traditional welding auxiliary fixtures are difficult to use, resulting in relatively low flexibility. Utility Model Content

[0004] The purpose of this utility model is to provide a welding auxiliary fixture for galvanized welded steel parts to prevent zinc layer damage. It solves the problem that traditional welding auxiliary fixtures usually clamp two sets of steel vertically when assisting in the clamping of steel before welding. When encountering steel that needs to be welded at an angle, traditional welding auxiliary fixtures are difficult to meet the requirements of angled auxiliary clamping, resulting in relatively low flexibility of use.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a welding auxiliary fixture for preventing zinc layer damage to galvanized welded steel parts, including a first clamping assembly, a second clamping assembly, and an adjustment mechanism. The first clamping assembly is rotatably connected to the second clamping assembly through the adjustment mechanism. Rubber pads are installed at the clamping ends of both the first clamping assembly and the second clamping assembly.

[0007] Furthermore, the first clamping assembly includes a first fixed shell, the interior of which is threaded with a first adjusting screw, one end of which is fixedly mounted with a first adjusting handle, and the end of the first adjusting screw away from the first adjusting handle is rotatably connected to a first clamping block. The interior of the first fixed shell has two sets of first sliding grooves, and the first clamping block and the interior of the first sliding grooves are slidably connected.

[0008] Furthermore, the second clamping assembly includes a second fixed housing, the interior of which is threaded with a second adjusting screw, one end of which is fixedly mounted with a second adjusting handle, and the end of the second adjusting screw away from the second adjusting handle is rotatably connected to a second clamping block. The interior of the second fixed housing has two sets of second sliding grooves, and the interiors of the second clamping block and the second sliding grooves are slidably connected.

[0009] Furthermore, the adjustment mechanism includes a limiting shell, one end of the second fixed shell is fixedly installed with the limiting shell, and a rotating rod is rotatably connected inside the limiting shell.

[0010] Furthermore, a connecting block is fixedly installed on the circumferential side of the rotating rod, one end of the connecting block is fixedly connected to the outer surface of the first fixed shell, a screw is fixedly installed on one end of the rotating rod, a locking sleeve is threadedly connected to the outer surface of the screw, and a rotating handle is fixedly installed on the upper surface of the locking sleeve.

[0011] Furthermore, rubber pads are fixedly installed on the outer surfaces of both the first clamping block and the second clamping block.

[0012] This utility model has the following beneficial effects:

[0013] (1) When the welding angle needs to be adjusted, the first clamping component is rotatably connected to the second clamping component through the adjustment mechanism. Inside the limiting shell, the rotating rod can rotate around its own axis. The connecting block connects the first fixed shell and the rotating rod together. So when the rotating rod rotates, the angle of the first clamping component relative to the second clamping component will change. After the angle is adjusted, the locking sleeve is rotated by rotating the rotating handle. Since the screw and the locking sleeve are threadedly connected, the locking sleeve will move along the screw axis. The locking sleeve and the outer surface of the limiting shell abut against each other to lock the rotating rod, thus fixing the relative angle between the first clamping component and the second clamping component. This makes it convenient to clamp the steel parts under different welding angle requirements and meets the diverse welding needs.

[0014] (2) The present invention has rubber pads installed on the outer surfaces of the first clamping block and the second clamping block. When the galvanized welded steel parts are clamped, the rubber pads directly contact the surface of the steel parts, avoiding direct contact between the metal parts of the clamps and the galvanized layer on the surface of the steel parts, thus preventing damage to the galvanized layer during the clamping process.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 As shown, this utility model is a welding auxiliary fixture for preventing zinc layer damage to galvanized welded steel parts, including a first clamping component 1, a second clamping component 2 and an adjustment mechanism 3. The first clamping component 1 is rotatably connected to the second clamping component 2 through the adjustment mechanism 3. Rubber pads 4 are installed at the clamping ends of the first clamping component 1 and the second clamping component 2.

[0025] The first clamping assembly 1 includes a first fixed shell 101. A first adjusting screw 102 is threadedly connected to the inside of the first fixed shell 101. A first adjusting handle 103 is fixedly installed at one end of the first adjusting screw 102. A first clamping block 104 is rotatably connected to the end of the first adjusting screw 102 away from the first adjusting handle 103. Two sets of first sliding grooves 105 are opened inside the first fixed shell 101. The first clamping block 104 and the first sliding grooves 105 are slidably connected inside the first clamping block 104.

[0026] The first clamping assembly 1 rotates the first adjusting handle 103, which drives the first adjusting screw 102 to rotate. Since the first adjusting screw 102 is threadedly connected to the first fixed shell 101, the first adjusting screw 102 will move along its axial direction during rotation. The first adjusting screw 102 pushes the first clamping block 104 to slide in the first slide groove 105, thereby changing the distance between the first clamping block 104 and the first fixed shell 101, so as to clamp one of the workpieces.

[0027] The second clamping assembly 2 includes a second fixed shell 201. A second adjusting screw 202 is threadedly connected to the inside of the second fixed shell 201. A second adjusting handle 203 is fixedly installed at one end of the second adjusting screw 202. A second clamping block 204 is rotatably connected to the end of the second adjusting screw 202 away from the second adjusting handle 203. Two sets of second sliding grooves 205 are opened inside the second fixed shell 201. The second clamping block 204 and the second sliding grooves 205 are slidably connected inside the second clamping block 204 and the second sliding grooves 205.

[0028] Similarly, for the second clamping assembly 2, rotate the second adjusting handle 203 to make the second adjusting screw 202 rotate. The second adjusting screw 202 pushes the second clamping block 204 to slide in the second slide groove 205 to complete the clamping of another workpiece. The workpiece clamped on the second clamping assembly 2 is then placed against the outer surface of the workpiece clamped on the first clamping assembly 1, and then the welding operation can be performed.

[0029] The adjustment mechanism 3 includes a limiting shell 301. One end of the second fixed shell 201 is fixedly installed with the limiting shell 301, and a rotating rod 302 is rotatably connected inside the limiting shell 301.

[0030] A connecting block 303 is fixedly installed on the circumferential side of the rotating rod 302. One end of the connecting block 303 is fixedly connected to the outer surface of the first fixed shell 101. A screw 304 is fixedly installed on one end of the rotating rod 302. A locking sleeve 305 is threadedly connected to the outer surface of the screw 304. A rotating handle 306 is fixedly installed on the upper surface of the locking sleeve 305.

[0031] When the welding angle needs to be adjusted, the first clamping assembly 1 is rotatably connected to the second clamping assembly 2 through the adjustment mechanism 3. Inside the limiting shell 301, the rotating rod 302 can rotate around its own axis. The connecting block 303 connects the first fixed shell 101 and the rotating rod 302 together. Therefore, when the rotating rod 302 rotates, the angle of the first clamping assembly 1 relative to the second clamping assembly 2 will change. After the angle is adjusted, the locking sleeve 305 is rotated by rotating the rotating handle 306. Since the screw 304 is threadedly connected to the locking sleeve 305, the locking sleeve 305 will move along the axial direction of the screw 304. The locking sleeve 305 and the outer surface of the limiting shell 301 abut against each other to lock the rotating rod 302, thereby fixing the relative angle between the first clamping assembly 1 and the second clamping assembly 2. This facilitates the clamping of steel parts under different welding angle requirements and meets diverse welding needs.

[0032] Rubber pads 4 are fixedly installed on the outer surfaces of the first clamping block 104 and the second clamping block 204;

[0033] Rubber pads 4 are installed on the outer surfaces of the first clamping block 104 and the second clamping block 204. When clamping galvanized welded steel parts, the rubber pads 4 directly contact the surface of the steel parts, avoiding direct contact between the metal parts of the clamps and the galvanized layer on the surface of the steel parts, thus preventing damage to the galvanized layer during the clamping process.

[0034] In use, the first clamping assembly 1 first rotates the first adjusting handle 103, which drives the first adjusting screw 102 to rotate. Since the first adjusting screw 102 is threadedly connected to the first fixed shell 101, the first adjusting screw 102 will move along its axial direction during rotation. The first adjusting screw 102 pushes the first clamping block 104 to slide in the first slide groove 105, thereby changing the distance between the first clamping block 104 and the first fixed shell 101, so as to clamp one of the workpieces.

[0035] Similarly, for the second clamping assembly 2, rotate the second adjusting handle 203 to make the second adjusting screw 202 rotate. The second adjusting screw 202 pushes the second clamping block 204 to slide in the second slide groove 205 to complete the clamping of another workpiece. The workpiece clamped on the second clamping assembly 2 is then placed against the outer surface of the workpiece clamped on the first clamping assembly 1, and then the welding operation can be performed.

[0036] When the welding angle needs to be adjusted, the first clamping assembly 1 is rotatably connected to the second clamping assembly 2 through the adjustment mechanism 3. Inside the limiting shell 301, the rotating rod 302 can rotate around its own axis. The connecting block 303 connects the first fixed shell 101 and the rotating rod 302 together. Therefore, when the rotating rod 302 rotates, the angle of the first clamping assembly 1 relative to the second clamping assembly 2 will change. After the angle is adjusted, the locking sleeve 305 is rotated by rotating the rotating handle 306. Since the screw 304 is threadedly connected to the locking sleeve 305, the locking sleeve 305 will move along the axial direction of the screw 304. The locking sleeve 305 and the outer surface of the limiting shell 301 abut against each other to lock the rotating rod 302, thereby fixing the relative angle between the first clamping assembly 1 and the second clamping assembly 2. This facilitates the clamping of steel parts under different welding angle requirements and meets diverse welding needs.

[0037] Rubber pads 4 are installed on the outer surfaces of the first clamping block 104 and the second clamping block 204. When clamping galvanized welded steel parts, the rubber pads 4 directly contact the surface of the steel parts, avoiding direct contact between the metal parts of the clamps and the galvanized layer on the surface of the steel parts, thus preventing damage to the galvanized layer during the clamping process.
