Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a novel automobile V-rod welding device. Background Art

[0002] With the development of the economy and science and technology, automobiles have become the primary means of transportation. Auto parts are the components that make up a car and the products that serve it. There are many different types of auto parts. With the improvement of living standards, people are increasingly spending on cars, and the auto parts market is growing. In recent years, auto parts manufacturers have also experienced rapid growth. With the rapid development of auto parts manufacturing technology, manufacturing equipment and auxiliary devices have become increasingly efficient and sophisticated. For example, auto parts such as V-bars and torsion bars are now mostly automated.

[0003] refer to Figure 1The automobile V-rod (also known as the V-thrust rod) is a component used to maintain the stability of the axle. It is mainly composed of two connecting rods 1' and an upper ball seat 2'. One end is connected to the axle, and the other end is connected to the frame. The automobile V-rod cooperates with other components that stabilize the axle to ensure the longitudinal stability of the axle when the vehicle is driving or braking. However, when welding the connecting rod 1' and the upper ball seat 2' of the existing automobile V-rod, due to the shape of the upper ball seat 2', the welding between it and the connecting rod 1' often deviates, that is, the connecting rod 1' and the upper ball seat 2' branch pipe cannot be stably and firmly coaxially welded. At the same time, the welding method used in the existing technology is carbon dioxide gas shielded welding, which will produce sparks during the process, making subsequent cleaning difficult and requiring special protection. The welding wire and welding gun are easy to clog. After cleaning the welding gun, the welding wire needs to be adjusted synchronously for neutrality. If forgotten, it will cause biased welding. For welding thicker parts, two welding passes are generally required, and the welding time is long. Furthermore, improper selection of welding current and voltage can easily lead to problems such as cold welds and incomplete fusion, while also causing significant environmental pollution. Therefore, friction welding is a new option. For example, Chinese patent document CN202220243772.8 discloses a welding fixture for friction welding a drive shaft. The fixture is used to clamp a drive shaft formed by coaxially connecting a universal joint fork, a shaft tube, and a splined sleeve. The fixture comprises: a first clamp unit for clamping the universal joint fork; a second clamp unit for clamping the shaft tube; and a third clamp unit rotatably connected to the shaft end seat for clamping the splined sleeve. Under the clamping action of the first, second, and third clamp units, the universal joint fork, shaft tube, and splined sleeve are coaxially aligned. This fixture effectively addresses the problems of the prior art, ensuring reliable and stable locking of the universal joint fork, shaft tube, and splined sleeve while also offering excellent adjustability, versatility, and interchangeability. However, since the upper ball seat 2' of the V-rod is difficult to position during welding in order to ensure its coaxiality with the connecting rod 1', it is inconvenient to clamp it when using a friction welding device, and the welding efficiency is low. Utility Model Content

[0004] Therefore, in order to solve the above problems, the present invention proposes a novel automobile V-rod welding device which is easy to use, effective and stable in clamping and ensuring the coaxiality of the V-rod welding.

[0005] In order to solve this technical problem, the present invention adopts the following solution: a novel automobile V-rod welding device, comprising a machine tool, a first drive mechanism, a first clamp unit provided on the right side of the machine tool for clamping a connecting rod of the V-rod, and a second clamp unit provided on the left side of the machine tool for clamping an upper ball seat of the V-rod, the second clamp unit comprising an axis end seat of a rotating power end and a rotating clamp seat which can be adjusted in the radial direction and clamps the upper ball seat of the V-rod, the rotating clamp seat being locked on the axis end seat of the rotating power end, the first drive mechanism being provided on the machine tool and the output end of the first drive mechanism being connected to and driving the second clamp unit horizontally toward the first clamp unit The first clamp unit moves back and forth, and includes a seat body, an upper hydraulic clamping block and a lower hydraulic clamping block which are radially distributed upward and downward on the seat body and can clamp the connecting rod of the V-rod. The rotating clamping seat includes a support seat provided at the lower part of the shaft end seat and a hydraulic pressure block provided at the upper part of the shaft end. The upper surface of the support seat is provided with an upwardly protruding arc-shaped limiting portion, and the arc-shaped limiting portion is adapted to the inner diameter of the upper ball seat. The upper middle part of the shaft end seat is provided with an arc-shaped recessed portion adapted to one side of the upper ball seat end. The hydraulic pressure block can be pressed down to cooperate with the support seat and the arc-shaped recessed portion to clamp and position the upper ball seat of the V-rod or lift up to release and remove the processed workpiece.

[0006] A further improvement also includes a support clamp seat, which is arranged on the machine tool between the first clamp unit and the second clamp unit, and the support clamp seat is provided with a clamping hole for the connecting rod of the V rod to pass through and be clamped.

[0007] A further improvement includes a second drive mechanism, which is arranged on the machine tool and the output end of the second drive mechanism is connected to and drives the first clamp unit to move horizontally back and forth toward the second clamp unit.

[0008] As a further improvement, the upper hydraulic clamping block and the lower hydraulic clamping block of the first clamp unit are respectively provided with arc grooves adapted to the connecting rod of the V-rod on their surfaces facing each other.

[0009] As a further improvement, the first driving mechanism is a hydraulic cylinder or a motor screw.

[0010] By adopting the above-mentioned technical scheme, the beneficial effect of the utility model is as follows: by newly designing the rotating clamping seat of the second clamping unit on the machine tool, a raised arc-shaped limiting part adapted to the inner diameter of the V-rod upper ball seat is provided on the support seat at the lower part of the shaft end seat, and an arc-shaped recessed part adapted to one side of the end of the V-rod upper ball seat is provided in the middle and upper part of the shaft end seat, which cooperates with the hydraulic pressure block provided on the upper part of the shaft end, so that when the upper ball seat of the V-rod and the connecting rod are friction-welded, the upper ball seat is placed in the rotating clamping seat. At this time, the lower part of the upper ball seat is sleeved on the arc-shaped limiting part and the upper end of the upper ball seat is tilted on the arc-shaped recessed part so that the branch connecting the upper ball seat and the connecting rod can maintain a horizontal axial direction. The hydraulic pressure block presses down the top of the upper ball seat from the top, so that the upper ball seat can be reliably, stably and quickly positioned, so that the hydraulic pressure block can be pressed down to cooperate with the support seat and the arc-shaped recessed part to clamp and position the upper ball seat of the V-rod or lift up to release and remove it. The processed workpiece has one end of the connecting rod of the V-rod clamped by the first clamp unit, thereby driving the second clamp unit toward the first clamp unit through the first driving mechanism, and the shaft end seat at the rotating power end rotates to drive the ball seat on the V-rod and the free end of the connecting rod away from the first clamp unit for rotational friction welding. The effective and stable clamping ensures the coaxiality of the welding of the ball seat on the V-rod and the connecting rod, and the welding quality is good. The first clamp unit and the second clamp unit are both driven by a hydraulic system for clamping, which is easy to use. It only needs to control the start and stop to place the workpiece and remove the welded workpiece to complete the welding. The welding speed is fast and the welding efficiency is high. The setting of the support clamp seat allows the connecting rod to be clamped and positioned at two points by the support clamp seat and the first clamp unit, making the overall welding structure more stable and not deviating, ensuring the coaxiality and concentricity of the upper ball seat of the V-rod and the connecting rod more accurate, and can be widely promoted and applied.
