Description

Technical Field

[0001] This utility model relates to the technical field of fixtures, specifically a welding fixture for automobile manufacturing. Background Technology

[0002] In automobile manufacturing, some parts need to be welded and fixed. To ensure welding dimensions, improve assembly accuracy and efficiency, and prevent welding deformation, tooling fixtures are used to clamp and fix the parts to facilitate welding.

[0003] For example, Chinese utility model patent CN222002348U discloses an automated welding fixture for automobile manufacturing, including a base plate. Fixed frames are fixedly connected to the upper sides of both the left and right ends of the base plate. Lifting grooves are formed on both the front and rear sides of the fixed frames. Lifting blocks are slidably connected to the inner sides of the lifting grooves on both sides. A clamping unit is arranged between the lifting blocks on both sides. The clamping unit includes a connecting plate, which is fixedly connected between the lifting blocks on both sides. A moving groove is formed on the outer side of the connecting plate, and a moving plate is slidably connected to the inner side of the moving groove. An electric push rod is fixedly connected to the outer side of the moving plate. By including the base plate, fixed frames, connecting plate, screw, control plate, clamping plate, rotating rod, and cam, the clamping plates on both sides can easily clamp the automobile workpiece, control the workpiece to flip over, and repeatedly move it up and down to shake off debris from the workpiece surface, reducing the workload of cleaning personnel.

[0004] The existing clamping devices described above have poor clamping effect when clamping components by using only clamping plates. The clamping effect is even worse for ring-shaped components such as brake discs, which affects subsequent welding work. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a welding fixture for automobile manufacturing that facilitates clamping and fixing of annular components, increases the clamping range of the device on the components, ensures the subsequent welding effect of the components, and improves practicality.

[0006] This utility model discloses a welding fixture for automobile manufacturing, including a worktable, two vertical plates symmetrically fixedly installed on the top of the worktable, and multiple clamping mechanisms installed parallel between the two vertical plates; the clamping mechanism includes a fixing column, which is horizontally fixedly installed on the outer wall of one of the vertical plates, and multiple support mechanisms are symmetrically arranged on the outer wall of the fixing column. The support mechanism includes support rods. One end of the support rod's outer wall is rotatably connected to the outer wall of a fixed column via two rotating rods. A screw is horizontally screwed onto the outer wall of another vertical plate. A fixed cylinder is screwed onto one end of the screw, and a wedge is fixedly installed at the other end of the fixed cylinder. A guide rod is fixedly installed at the other end of the wedge. This automotive manufacturing welding fixture moves the component to be welded to one end of the corresponding adjacent support rod, allowing the component to move laterally on the outer side of each support rod. Simultaneously, the screw is rotated, and because the screw is screwed onto one of the vertical plates, it synchronously drives the fixed cylinder and wedge to move laterally. Guided by the guide rod, the outer wall of each support rod contacts the outer wall of the wedge, allowing the support rod to rotate under the limitation of the rotating rod. This stably fixes the component to the outer wall of each support rod, facilitating welding. This design is particularly useful for clamping and fixing annular components, increasing the clamping range of the device, ensuring the subsequent welding effect, and improving practicality.

[0007] Preferably, a fixing ring is slidably installed on the outer wall of the support rod on each fixed column. When the support rod is not in use, the fixing ring is used to gather each support rod together, which facilitates the connection and support between each support rod.

[0008] Preferably, two limiting grooves are symmetrically opened on the outer side wall of one of the upright plates, and a partition is slidably fitted on each limiting groove. The partition is slidably connected to the other upright plate. Two through holes are symmetrically opened on the outer side wall of the partition. When welding is required after the partition is fixed and clamped, it is slid to one of the upright plates and then slidably fitted to the limiting groove opened on the other upright plate, thereby blocking the welding debris through the partition.

[0009] Preferably, multiple limiting plates are fixedly installed in parallel on the outer side wall of each support rod. By installing the limiting plates, it is convenient to support and limit the fixed parts of different sizes, thereby improving the clamping effect of the device on the parts.

[0010] Preferably, each of the fixed columns has multiple support plates symmetrically fixedly installed at the end away from the upright plate, and each support plate is respectively attached to the bottom end of each support rod. By installing a support plate, it is easy to effectively limit the outer wall of the support rod for rotating operations.

[0011] Preferably, multiple anti-slip strips are fixedly installed in parallel on the outer side wall of each support rod. By installing anti-slip strips, the stability effect when the clamping component contacts the outer side wall of the support rod is improved.

[0012] Preferably, a collection trough is fixedly installed at the top of the workbench, and welding debris is collected through the collection trough after being separated by the partition and the upright plate.

[0013] Preferably, a fixing ring groove is provided in the middle area of ​​the outer side wall of each fixing column. The fixing ring groove fits and engages with the outer side wall of the fixing ring. When the support rod is in use, it engages with the outer side wall of the fixing ring through the fixing ring groove on the fixing column, which facilitates the placement of the fixing ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This welding fixture for automobile manufacturing moves the parts to be welded to one end of the corresponding adjacent support rods, and moves the parts laterally on the outside of each support rod. While rotating the screw, the screw and one of the vertical plates are screwed together, which in turn drives the fixed cylinder and the inclined block to move laterally. The guide rod guides the movement, so that the outer wall of each support rod contacts the outer wall of the inclined block, and the support rod rotates under the limit of the rotating rod, thereby stably fixing the parts to the outer wall of each support rod, and then performing welding operations on the parts. It is convenient for clamping and fixing ring-shaped parts, increases the clamping range of the device on the parts, ensures the subsequent welding effect of the parts, and improves practicality.
