Description

Technical Field

[0001] This utility model belongs to the field of tooling and fixture technology, specifically relating to a steel welding tooling and fixture. Background Technology

[0002] Welding is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. When welding steel structures, appropriate welding fixtures are required.

[0003] When welding two steel structures with a certain angle, existing steel welding fixtures often cannot adjust the angle of the fixed steel structure according to the angle of the steel structure. Since some welding devices can only perform welding in the horizontal direction, it is necessary to disassemble the steel structure and readjust and fix the angle before welding when welding steel structures with an angle. This makes it inconvenient for welding such steel structures with angles.

[0004] Therefore, a steel welding fixture is needed to solve the problem that most existing steel welding fixtures cannot adjust the angle of the steel structure during fixing according to the included angle of the steel structure. As a result, when welding steel structures with angles, it is necessary to disassemble the steel structure, readjust the angle, and fix it before welding. Utility Model Content

[0005] The purpose of this utility model is to provide a steel welding fixture to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a steel welding fixture, comprising a base, two moving plates disposed on the top of the base, a clamping seat disposed on the top of the moving plates, and an angle adjustment mechanism acting on the clamping seat;

[0007] The angle adjustment mechanism includes a support component and a transmission component;

[0008] The supporting component includes a rotating plate rotatably connected to one end surface of the top of the moving plate, two fixing blocks fixed to the other end of the top surface of the moving plate, a first threaded rod rotatably connected to the middle position of the two fixing blocks, a threaded sleeve threaded to the outer circumferential surface of the first threaded rod, an abutment groove formed on the bottom surface of the threaded sleeve, a fixing strip inserted through the middle position of the abutment groove, and a support rod hinged to the top of the threaded sleeve.

[0009] It should be noted in the solution that the transmission component includes a support fixed to one end surface of the moving plate, a first bevel gear fixedly sleeved on the outer circumferential surface of the rotating rod, and a second bevel gear fixedly sleeved on the outer circumferential surface of the first threaded rod near the rotating rod. The first bevel gear and the second bevel gear at the adjacent position are meshed together.

[0010] It is further worth noting that the transmission component also includes a rectangular slot that passes through the middle position of one of the rotating rods and a pin that passes through the middle position of the rectangular slot, with one side of the pin fixed to the surface of one side of the other rotating rod.

[0011] Furthermore, it should be noted that the top of the rotating plate is fixed to one end of the bottom surface of the clamp, one end of the first threaded rod passes through the adjacent fixing block and extends to the other end of the fixing block, the bottom of the fixing strip passes through the adjacent abutment groove and is fixed to the top surface of the moving plate, both ends of the fixing strip are fixed to the surface of the adjacent fixing block, and the top of the support rod is hinged to the other end of the bottom surface of the clamp.

[0012] As a preferred embodiment, it also includes a positioning mechanism for fixing the steel structure, the positioning mechanism including a spacing adjustment component and a clamping component.

[0013] In a preferred embodiment, the spacing adjustment component includes a storage slot at the top of the base located at both ends of the bottom of the motion plate, a slide block slidably inserted into both sides of the inner cavity of the storage slot, a third threaded rod threadedly connected to the middle position of two of the slide blocks, and a positioning shaft threadedly inserted into the middle position of the other two slide blocks. The top of the slide block passes through the interior of the adjacent storage slot and is fixed to the surface of the bottom of the adjacent motion plate. Both sides of the positioning shaft are fixed to the inner wall of the adjacent storage slot. One side of the third threaded rod is rotatably connected to the inner wall of the adjacent storage slot, and the other side of the third threaded rod passes through the base and extends to one side of the base.

[0014] In a preferred embodiment, the clamping component includes a second threaded rod that is threaded through and connected to the top surface of the clamping seat, and a rubber seat fixed to the bottom of the second threaded rod.

[0015] Compared with the prior art, the steel welding fixture provided by this utility model has at least the following beneficial effects:

[0016] 1. By rotating one of the first threaded rods, the threaded sleeve can move synchronously in the horizontal direction under the connection between the rotating rod and the insert, thereby causing the support rod to change angle. This allows the clamp to drive the steel structure with a certain angle to change angle when clamped and fixed, which makes it convenient for the user to adjust the angle of the steel structure when performing welding operations, thus facilitating the welding device to perform welding operations on the steel structure with an angle in the horizontal direction.

[0017] 2. The distance between the two clamps can be adjusted by rotating the insert, and the distance between the rubber seat and the bottom of the inner wall of the clamp can be adjusted by rotating the second threaded rod. This makes it easier to fix and connect two steel structures with a certain angle with different lengths and thicknesses, thereby improving the adaptability of the device.

[0023] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0024] Example 1

[0025] See also Figure 1-4This utility model provides a steel welding fixture, including a base 1, two moving plates 2 disposed on the top of the base 1, a clamping seat 3 disposed on the top of the moving plates 2, and an angle adjustment mechanism for the clamping seat 3;

[0026] The angle adjustment mechanism includes a support component and a transmission component;

[0027] The supporting components include a rotating plate 4 rotatably connected to one end of the top surface of the moving plate 2, two fixing blocks 5 fixed to the other end of the top surface of the moving plate 2, a first threaded rod 6 rotatably connected to the middle position of the two fixing blocks 5, a threaded sleeve 7 threadedly connected to the outer circumferential surface of the first threaded rod 6, an abutment groove 8 formed on the bottom surface of the threaded sleeve 7, a fixing strip 9 inserted through the middle position of the abutment groove 8, and a support rod 10 hinged to the top of the threaded sleeve 7.

[0028] See also Figure 1-4 The top of the rotating plate 4 is fixed to one end of the bottom surface of the clamp 3. One end of the first threaded rod 6 passes through the adjacent fixed block 5 and extends to the other end of the fixed block 5. The bottom of the fixing strip 9 passes through the adjacent abutting groove 8 and is fixed to the top surface of the moving plate 2. Both ends of the fixing strip 9 are fixed to the surface of the adjacent fixed block 5. The top of the support rod 10 is hinged to the other end of the bottom surface of the clamp 3.

[0029] When the first threaded rod 6 is rotated, the threaded sleeve 7 can only move horizontally due to the contact and restriction between the inner wall of the contact groove 8 and the surface of the fixing strip 9. Thus, the threaded sleeve 7 can move horizontally under the cooperation between the internal thread structure of the inner wall of the threaded sleeve 7 and the external thread structure of the outer circumference of the first threaded rod 6. This allows the support rod 10 to change angle. Due to the restriction effect of the rotating plate 4 on the clamp 3, the clamp 3 can change angle under the drive of the support rod 10. This allows the steel structure with a certain included angle fixed in the inner cavity of the clamp 3 to change angle, which facilitates the welding device to perform welding operations on the two sides of the steel structure with a certain angle.

[0030] See also Figure 1-4 The transmission component includes a support seat 21 fixed to one end surface of the moving plate 2, a first bevel gear 14 fixedly sleeved on the outer circumferential surface of the rotating rod 13, and a second bevel gear 15 fixedly sleeved on the outer circumferential surface of the first threaded rod 6 near the rotating rod 13. The first bevel gear 14 and the adjacent second bevel gear 15 are meshed together.

[0031] When the rotating rod 13 can rotate, it can drive the first bevel gear 14 at the adjacent position to rotate, so that the first threaded rod 6 can rotate under the meshing action between the first bevel gear 14 and the second bevel gear 15 at the adjacent position.

[0032] See also Figure 1-4 The transmission component also includes a rectangular slot 22 that passes through the middle position of one of the rotating rods 13 and a pin 16 that passes through the middle position of the rectangular slot 22. One side of the pin 16 is fixed to the surface of one side of the other rotating rod 13.

[0033] When one of the rotating rods 13 can rotate, it drives the insert 16 to rotate. Thus, under the abutment of the insert 16 and the rectangular groove 22, the other rotating rod 13 can rotate. Therefore, when one of the first threaded rods 6 is rotated, the other first threaded rod 6 can rotate synchronously, which facilitates the synchronous angle adjustment of the two steel structures with a certain angle.

[0034] Example 2

[0035] Further in the embodiments, please refer to Figure 1-4 As shown, it also includes a positioning mechanism for fixing the steel structure, which includes a spacing adjustment component and a clamping component;

[0036] The spacing adjustment component includes a storage slot 17 located at the top of the base 1 and at both ends of the bottom of the motion plate 2, a slide block 18 slidably inserted into both sides of the inner cavity of the storage slot 17, a third threaded rod 19 threaded through and connected to the middle position of two of the slide blocks 18, and a positioning shaft 20 threaded through and inserted into the middle position of the other two slide blocks 18. The top of the slide block 18 passes through the interior of the adjacent storage slot 17 and is fixed to the bottom surface of the adjacent motion plate 2. The two sides of the positioning shaft 20 are fixed to the inner wall of the adjacent storage slot 17. One side of the third threaded rod 19 is rotatably connected to the inner wall of the adjacent storage slot 17. The other side of the third threaded rod 19 passes through the base 1 and extends to one side of the base 1.

[0037] When it is necessary to adjust the distance between the two clamps 3 according to the length of the two steel structures, since the two slides 18 can only slide in the inner cavity of the adjacent placement groove 17 along the adjacent positioning shaft 20, and the external thread structures on both sides of the outer circumferential surface of the third threaded rod 19 are set in opposite directions, the distance between the two moving plates 2 can change under the cooperation between the internal thread structure on the inner wall of the slide 18 and the corresponding external thread structure on the outer circumferential surface of the third threaded rod 19, thereby adapting to steel structures of different lengths.

[0038] Please refer to Figure 1-4 As shown, the clamping component includes a second threaded rod 11 that is threaded through and connected to the top surface of the clamping seat 3, and a rubber seat 12 fixed to the bottom of the second threaded rod 11;

[0039] When it is necessary to fix steel structures of different thicknesses, one side of the steel structure is extended into the interior of the clamp 3, and the second threaded rod 11 is rotated so that it moves vertically downward under the action of the threaded structure between it and the clamp 3, so that the rubber seat 12 abuts against the steel structure, thereby achieving the clamping effect on steel structures of different thicknesses.
