Description

Technical Field

[0001] The utility model relates to the technical field of jigs, and particularly relates to a jig device for welding. Background Art

[0002] A welding jig is a jig used to fix and butt the parts to be welded during the welding process, which can keep the parts to be welded stable in different postures and states during the welding process, improve the assembly accuracy and efficiency of the parts to be welded, liberate the hands of the staff, facilitate the welding operation of the staff, and increase the stability and convenience during the welding operation.

[0003] When two parts are welded to form a right-angled part, it is necessary to cooperate with a welding jig for clamping and fixing. The existing welding jigs generally form clamping on the inner or outer side of the two parts. After clamping, the inner and outer included angles where the two parts form a right angle will be blocked, affecting the processing of the welding area. It is necessary to take out the parts from the jig after the parts are initially processed and shaped, and then perform secondary processing to weld the blocked inner and outer included angles. The operation process is cumbersome and very inconvenient. Summary of the Utility Model

[0004] Based on the above description, the utility model provides a jig device for welding, so as to solve the problem that when the existing welding jig clamps parts to form a right angle for welding, the inner and outer included angles of the parts will be blocked, resulting in incomplete processing of the welding area of the parts.

[0005] The technical solution for the utility model to solve the above technical problems is as follows: A jig device for welding includes a mold and a tail plate arranged at one end of the mold. A first positioning strip and a vertical rod are arranged on the outer side of the mold. An adjustable and movable positioning member is arranged on the outer side of the vertical rod. The positioning member is perpendicular to the first positioning strip at a right angle. A threaded jig is installed inside the tail plate. The threaded jig moves horizontally along the surface of the mold by rotation and cooperates with the positioning member and the first positioning strip to form clamping.

[0006] On the basis of the above technical solution, the utility model can be further improved as follows.

[0007] Further, a notch is opened at the center of the end of the mold far from the tail plate. The two ends of the inner wall of the notch are perpendicular to each other. A threaded hole is opened at the center of the surface of the tail plate.

[0008] Further, the first positioning strip is arranged on the surface of the mold and is located at one end of the notch. The vertical rod is arranged on the surface of the mold and is located at the other end of the notch. There are two vertical rods, and the two vertical rods are perpendicular to the first positioning strip.

[0009] Further, the positioning member includes a second positioning strip and jacks. The jacks are evenly distributed and opened in the center of the surface of the second positioning strip. The second positioning strip is installed on the outer sides of the two vertical rods through the jacks and fits the surface of the mold. The second positioning strip is perpendicular to the first positioning strip.

[0010] Further, the threaded clamp includes a threaded rod, a plain bearing, a clamping block, and a grip. The threaded rod is installed in the threaded hole. The plain bearing is installed at one end of the threaded rod close to the first positioning strip. The grip is installed at the other end of the threaded rod.

[0011] Further, the clamping block is installed at one end of the plain bearing away from the tail plate and fits the surface of the mold. One end of the clamping block away from the tail plate is arranged in an isosceles trapezoid shape and is parallel to the second positioning strip and the first positioning strip.

[0012] Compared with the prior art, the technical solution of the present application has the following beneficial technical effects:

[0013] In the present utility model, the first positioning strip and the second positioning strip are arranged at both ends of the notch, cooperating with the threaded rod installed in the threaded hole and the clamping block at one end of the threaded rod. The first positioning strip and the second positioning strip are perpendicular to each other and there is a gap between them. One end of the clamping block is parallel to the first positioning strip and the second positioning strip. Under the rotation adjustment of the threaded rod, the clamping block can horizontally move along the surface of the mold to control the size of the gap between the first positioning strip and the second positioning strip, so that parts of different sizes can be clamped between the clamping block, the first positioning strip and the second positioning strip to form a right-angle fixation. One end of the clamping block close to the included angle of the part is arranged in a plane. Cooperating with the notch and the gap between the first positioning strip and the second positioning strip, when the part is clamped for welding, the clamping block and other structures will not block the welding points of the part, and the welding points of the part are fully displayed, avoiding the situation where the welding points are blocked and secondary processing is required, so that the welding can be completely carried out during the clamping, ensuring the stability during the welding process.

[0019] To facilitate the understanding of this application, the following will describe this application more comprehensively with reference to the relevant attached drawings. Embodiments of this application are shown in the attached drawings. However, this application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of this application more thorough and comprehensive.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which this application belongs. The terms used in the specification of this application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0021] Please refer to Figures 1-3 , a welding fixture device of the present utility model includes a mold 1 and a tail plate 11 provided at one end of the mold 1. A first positioning strip 3 and a vertical rod 4 are provided on the outer side of the mold 1. An adjustable and movable positioning part 5 is provided on the outer side of the vertical rod 4. The positioning part 5 is perpendicular to the first positioning strip 3 at 90 degrees. A threaded clamp 6 is installed inside the tail plate 11. The threaded clamp 6 moves horizontally along the surface of the mold 1 by rotation and cooperates with the positioning part 5 and the first positioning strip 3 to form clamping.

[0022] Please refer to Figure 1 , a notch 12 is opened at the center of the end of the mold 1 away from the tail plate 11. The two ends of the inner wall of the notch 12 are perpendicular to each other. A threaded hole 2 is opened at the center of the surface of the tail plate 11. The setting of the notch 12 expands the space between the first positioning strip 3 and the second positioning strip 51, avoiding the mold 1 from blocking the area between the first positioning strip 3 and the second positioning strip 51. When the parts are installed and fixed between the first positioning strip 3 and the second positioning strip 51, the welding points of the part docking are exposed at the position of the notch 12.

[0023] Please refer to Figure 2 , the first positioning strip 3 is provided on the surface of the mold 1 and is located at one end of the notch 12. The vertical rod 4 is provided on the surface of the mold 1 and is located at the other end of the notch 12. There are two vertical rods 4. The two vertical rods 4 are perpendicular to the first positioning strip 3. The perpendicular setting of the vertical rod 4 and the first positioning strip 3 enables the second positioning strip 51 to also be perpendicular to the first positioning strip 3 after being installed on the outer side of the vertical rod 4. The perpendicular cooperation of the first positioning strip 3 and the second positioning strip 51 can position the parts to be welded in a vertical state.

[0024] Please refer toFigure 2 The positioning member 5 includes a second positioning strip 51 and jacks 52. The jacks 52 are evenly distributed and opened in the center of the surface of the second positioning strip 51. The second positioning strip 51 is installed on the outer sides of the two vertical rods 4 through the jacks 52 and fits the surface of the mold 1. The second positioning strip 51 is perpendicular to the first positioning strip 3. The second positioning strip 51 can move on the outer sides of the vertical rods 4 by inserting and pulling to adjust the gap with the first positioning strip 3, so as to adapt to the installation of parts of different sizes between the first positioning strip 3 and the second positioning strip 51 for fixation, avoiding that the gap between the first positioning strip 3 and the second positioning strip 51 is too small to block the solder joints of the fixed parts.

[0025] Please refer to Figure 1 The threaded clamp 6 includes a threaded rod 61, a plain bearing 62, a clamping block 63 and a handle 64. The threaded rod 61 is installed in the threaded hole 2. The plain bearing 62 is installed at one end of the threaded rod 61 close to the first positioning strip 3. The handle 64 is installed at the other end of the threaded rod 61. When the threaded rod 61 rotates and moves in the threaded hole 2, the clamping block 63 at one end of the threaded rod 61, due to fitting the surface of the mold 1 and being connected to the threaded rod 61 through the plain bearing 62, can only move horizontally by fitting the surface of the mold 1 when the threaded rod 61 rotates and moves.

[0026] Please refer to Figure 1 The clamping block 63 is installed at one end of the plain bearing 62 away from the tail plate 11 and fits the surface of the mold 1. The end of the clamping block 63 away from the tail plate 11 is arranged in an isosceles trapezoid shape and is parallel to the second positioning strip 51 and the first positioning strip 3. The two sides of the end of the clamping block 63 arranged in an isosceles trapezoid shape and close to the first positioning strip 3 and the second positioning strip 51 are inclined and parallel to the first positioning strip 3 and the second positioning strip 51. When the clamping block 63 moves, clamping can be formed between the inclined surfaces of the clamping block 63 and the first positioning strip 3 and the second positioning strip 51. One side of the clamping block 63 located between the first positioning strip 3 and the second positioning strip 51 is arranged in a plane between the first positioning strip 3 and the second positioning strip 51. When the clamping block 63 cooperates with the first positioning strip 3 and the second positioning strip 51 to clamp the part at a right angle, the clamping block 63 will not block the inner included angle where the part is spliced into a right angle shape. With the cooperation of the notch 12 and the gap between the first positioning strip 3 and the second positioning strip 51, when the part is clamped and welded, the solder joints of the part are fully displayed, and the welding can be carried out during the clamping, ensuring the stability during the welding process.

[0027] When it is necessary to splice and weld parts, first place the two parts on the surface of the mold 1 and respectively fit them with the first positioning strip 3 and the second positioning strip 51. Then move the two parts to form a ninety-degree angle. Next, rotate the threaded rod 61 in the threaded hole 2. The threaded rod 61 moves in a spiral manner, pushing the clamping block 63 towards the parts. The clamping block 63 cooperates with the first positioning strip 3 and the second positioning strip 51 to clamp the parts. Workers can perform welding through the gap between the first positioning strip 3 and the second positioning strip 51, the notch 12, and the gap between the clamping block 63 and the inner angle formed by the two parts.
