Description

Technical Field

[0001] This utility model relates to the field of automotive driveshaft manufacturing, specifically to an automatic ring welding device for driveshaft tubes. Background Technology

[0002] The driveshaft is a crucial component in a car's transmission system, transmitting power. Working in conjunction with the gearbox and differential, the driveshaft transmits engine torque to the wheels, propelling the vehicle. Driveshafts connect two shafts that are not aligned in a straight line, typically using a universal joint to accommodate changes in angle. Generally, the universal joint and the shaft tube are not integrally formed; in particular, to reduce the overall weight of the driveshaft tube, the tube is usually hollow. To achieve a more seamless connection between the universal joint and the shaft tube... Figure 2 The finished drive shaft shown in Figure a (unpainted) requires the end components used in the universal joint to be welded to the shaft tube before assembly. Since the connection part needs to be welded around, an automatic welding equipment needs to be designed. Summary of the Invention

[0006] Each of the two vertical hanging arms is equipped with an adjustable automatic lifting welding torch;

[0007] An adjustable automatic lifting welding torch includes: a slide rail device, the track of the slide rail device is fixed on a vertical hanging arm, the moving axis of the track is perpendicular to the ground, a first vertical telescopic cylinder is fixed at one end of the track, and a slider is fixedly connected to the telescopic end of the first vertical telescopic cylinder.

[0008] A detachable extension rod is provided on the slider of the slide rail device, and a welding gun bracket is provided on the first end of the detachable extension rod;

[0009] The welding torch holder is equipped with a limiting plate and a welding torch holder. The welding torch holder is hinged to the limiting plate. The limiting plate is provided with an arc-shaped elongated hole. The welding torch holder is provided with a protrusion that engages with the arc-shaped elongated hole. The welding torch is placed inside the welding torch holder.

[0010] Preferably, the roller support device includes two mirror-arranged single-sided telescopic roller support devices.

[0011] The single-side telescopic roller device comprises a horizontally arranged U-shaped track, a telescopic cylinder and a cover shell.

[0012] Two rollers are arranged in the U-shaped track, and a long waist hole is arranged on the vertical part of the U-shaped track; the roller shaft is clamped into the long waist hole of the U-shaped track.

When the transmission shaft is clamped between the main shaft chuck and the telescopic chuck device, the shaft tube of the transmission shaft is clamped between the two rollers of the first roller device and the second roller device due to the fact that the end cover and the shaft tube at the end are not welded. When the welding is opened and one point is welded, the shaft tube on the roller device also rotates synchronously due to the fact that the main drive box rotates.

[0015] As preferred, the telescopic chuck device comprises a horizontal light pole coaxially arranged with the main shaft box, a hole-fixed seat for fixing the light pole, a second chuck arranged on the side close to the main shaft box, and a fixing plate arranged on the other side. A sixth telescopic cylinder is arranged on the lower side of the hole-fixed seat, and the telescopic end is fixedly connected with the fixing plate. The second chuck is in connection with the end of the light pole, and the second chuck rotates synchronously when the main shaft box drives the transmission shaft to rotate.

[0016] The position of the second chuck on the telescopic chuck device is adjusted to adapt to the loading and unloading process.

[0017] The beneficial effect of the utility model lies in that the welding can be automatically completed by fixing the end cover (including universal joint or other types of end cover) of the shaft tube on the chuck, placing the shaft tube on the roller device and adjusting the position, which simplifies the manual operation and optimizes the product qualification rate.
