Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder welding equipment, specifically to a welding device for a dump truck lifting cylinder. Background Technology

[0002] The lifting cylinder is a key component of the semi-trailer lifting system, mainly used to control the tilting and unloading actions of the semi-trailer. Powered by a hydraulic system, the lifting cylinder enables the semi-trailer to tip over to the side or rear, thus facilitating the unloading of cargo.

[0003] The lifting cylinder of a semi-trailer typically consists of components such as a cylinder barrel, cylinder bottom, piston, piston rod, and end caps. During the production process, the cylinder bottom is first welded to the cylinder barrel, the piston and end caps are then mounted on the piston rod, and finally, the piston rod is assembled to the cylinder barrel. However, existing welding equipment is often vertical, requiring lifting equipment for clamping, resulting in high clamping costs.

[0004] Therefore, a new technical solution is needed in this field to solve the above problems. Summary of the Invention

[0005] To improve or solve the technical problem of high clamping cost in existing vertical welding devices, this utility model provides a welding device for a dump truck lifting cylinder. The welding device includes: a worktable; a cylinder clamping structure, including a mounting cylinder rotatably mounted on the worktable, a tension rod coaxially arranged with the mounting cylinder, clamping members with their two ends respectively mounted on the tension rod and the mounting cylinder, and a power source for driving the tension rod to extend and retract within the mounting cylinder; a cylinder bottom clamping structure, including a sliding seat slidably mounted on the worktable, a rotating disk rotatably mounted on the sliding seat, an electromagnetic chuck mounted on the rotating disk, and a drive source for driving the rotating disk to rotate; and a welding structure, including a mounting rod mounted on the worktable, a lifting seat rotatably mounted on the mounting rod, and a welding head mounted on the lifting seat.

[0006] This utility model discloses a welding device for a dump truck lifting cylinder, comprising a worktable, a cylinder clamping structure, a cylinder bottom clamping structure, and a welding structure. The worktable is used to mount the aforementioned structures. The cylinder clamping structure includes a mounting cylinder, a tension rod, a clamping component, and a power source. The power source drives the tension rod to extend and retract, thereby moving one end of the clamping component, causing it to protrude from the mounting cylinder and abut against the cylinder, thus clamping the cylinder. The cylinder bottom clamping structure includes a sliding seat, a rotating disk, an electromagnetic chuck, and a drive source. The drive source drives the rotating disk to rotate, thereby rotating the electromagnetic chuck and the cylinder bottom held by it. The sliding seat moves the electromagnetic chuck and the cylinder bottom to mate with the cylinder, and then rotates after mate, allowing the welding structure to perform welding. Through the above configuration, the cylinder clamping structure and cylinder bottom clamping structure in this utility model's welding device for a dump truck lifting cylinder can conveniently clamp and fix the cylinder and cylinder bottom, reducing the assembly cost of the welding device.

[0007] Furthermore, the clamping member includes a first support mounted on the tension rod, an abutment adapted to abut against the cylinder, a second support mounted on the mounting cylinder, a first arm with both ends hinged to the first support and the abutment respectively, and a second arm with both ends hinged to the second support and the abutment respectively.

[0008] Furthermore, the mounting cylinder is provided with a clearance groove to avoid the abutment, the first support arm, and the second support arm.

[0009] Furthermore, the power source is a tension cylinder.

[0010] Furthermore, a support plate is provided inside the mounting cylinder.

[0011] Furthermore, a worm gear is provided on the outer circumferential side of the mounting cylinder, and a worm gear matching the worm gear is provided on the worktable, with the worm gear connected to a first drive motor.

[0012] Furthermore, a lead screw is rotatably arranged on the worktable, and a slide table matching the lead screw is provided on the sliding seat.

[0013] In summary, compared with the prior art, this utility model has the following beneficial effects:

[0014] The cylinder clamping structure includes a mounting cylinder, a tension rod, a clamping component, and a power source. The power source can drive the tension rod to extend and retract, thereby moving one end of the clamping component so that it protrudes from the mounting cylinder and abuts against the cylinder, thus clamping the cylinder. The cylinder bottom clamping structure includes a sliding seat, a rotating disk, an electromagnetic chuck, and a drive source. The drive source can drive the rotating disk to rotate, thereby rotating the electromagnetic chuck and the cylinder bottom attracted by the electromagnetic chuck. The sliding seat can drive the electromagnetic chuck and the cylinder bottom to move, thereby docking with the cylinder, and then rotating after docking to facilitate welding of the structure.
