Technical Field

[0001] This utility model belongs to the field of fixing fixture technology, and in particular relates to a fixing fixture for welding. Background Technology

[0002] Welding, as a core process for joining materials in the manufacturing industry, is widely used in key fields such as automobile manufacturing, aerospace, shipbuilding, and engineering machinery. Its processing accuracy and efficiency directly determine the performance and quality of the end product. During the welding process, high-temperature heat input can easily cause thermal expansion and contraction of the workpiece, while the vibration of the welding tool may cause workpiece displacement. These two factors directly affect the weld formation accuracy and joint strength, and may cause permanent deformation of the workpiece. Therefore, accurate positioning and stable clamping of the workpiece have become key links to ensure welding quality. Welding fixtures have thus become an indispensable core auxiliary equipment for welding operations.

[0003] However, when using existing fixtures, special fixtures are required to replace them with those for workpieces with large height differences. This not only increases equipment procurement costs but also prolongs the preparation time for workpiece changeover and reduces overall welding efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing fixture for welding. By setting up a clamping part, it solves the problem that existing fixing fixtures require the replacement of special fixtures when dealing with workpieces with large height differences. This not only increases equipment procurement costs but also prolongs the preparation time for workpiece changeover and reduces overall welding efficiency.

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

[0006] This utility model relates to a fixing fixture for welding, comprising a fixing plate and further comprising: a clamping part, wherein a plurality of clamping parts are provided and all of the clamping parts are mounted on the fixing plate; an adjusting part, wherein the adjusting part is disposed on the fixing plate; the clamping part includes an adjusting assembly, wherein the adjusting assembly is disposed on the fixing plate; and a hinge assembly, wherein the hinge assembly is mounted on the fixing plate; the adjusting assembly includes a hollow rod disposed above the fixing plate, wherein a limiting groove is formed on the hollow rod, and a limiting groove is formed at the top of the hollow rod, wherein a sliding rod is slidably connected within the limiting groove, and a limiting element is provided on the outer wall of the sliding rod; the clamping part is mounted on the fixing plate through the adjusting part, and the limiting element includes a plurality of limiting rods fixedly connected to the outer wall of the sliding rod, wherein the plurality of limiting rods are adapted to the limiting groove, and the corresponding limiting rods are engaged within the limiting groove.

[0007] Furthermore, the adjustment part includes a mounting component disposed on a fixed plate; and a connecting component, wherein a plurality of connecting components are disposed and all of the connecting components are mounted on the fixed plate, and both the mounting component and the connecting component are located within the fixed plate.

[0008] Furthermore, the hinge assembly includes an electric telescopic rod fixedly connected to the inner wall of the bottom of the hollow rod. The output end of the electric telescopic rod is fixedly connected to a hinge block one, and the top of the slide rod is fixedly connected to a hinge block two. A hinge rod is hinged to the top of the hinge block one, and the hinge block two is hinged to the hinge rod. A buffer is provided on the hinge rod.

During adjustment, first rotate the slide rod 214. At this time, the slide rod 214 will rotate along with the limiting rod 215. After the limiting rod 215 rotates to coincide with the limiting slide groove 212, pull the slide rod 214 upward. At this time, the second hinge block 223 at the top of the slide rod 214 will push the hinge rod 224 upward. The electric telescopic rod 221 and the first hinge block 222 will also move in coordination with the movement of the hinge rod 224. After the limiting rod 215 reaches a certain position, rotate the slide rod 214 and the limiting rod 215 so that the corresponding limiting rod 215 is locked in the first limiting groove 213. In this way, the effect of adapting to different item heights can be achieved.
