Description

Automatic clamping device for welding of flange parts of loading machine

Technical Field

The utility model relates to an automatic clamping device when loader flange part welds belongs to loader technical field.

Background

When the existing loader flange part is welded, in order to ensure that a welding seam is even and continuous, the existing loader flange part is ensured not to be welded when being subjected to severe working conditions. Most of the welding guns are fixed, and an automatic rotating mechanism drives the flange parts to carry out ship-shaped welding. The traditional clamping mode during welding of the flange part of the loader is that the flange part is blocked by adopting a baffle with an opening, is locked by bolts manually, ensures that the flange part and a flitch are tightly attached together, and then is welded. As shown in fig. 1, the flitch plate 1 and the flange 2 need to be welded. This scheme is relatively laggard, needs manual operation intensity of labour big, and is efficient.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: how to change the clamping mode when traditional loader flange part welds, it is big to solve needs manual operation intensity of labour, the problem of inefficiency.

In order to solve the technical problem, the technical scheme of the utility model a self-holding device when providing a loader flange part welding, its characterized in that is equipped with the cylinder on the automatic rotary mechanism, and the dabber is connected to the cylinder, is equipped with the draw-in groove on the dabber, is equipped with on the draw-in groove and is equipped with the spring, and dabber installation draw-in groove end is the toper structure.

Preferably, the mandrel is made of round steel.

Preferably, one end of the mandrel is provided with a threaded hole connected with the cylinder, and the other end of the mandrel is of a conical structure.

Preferably, the clamping groove is a circular baffle structure formed by combining four quadrant sector structures, and is arranged on the conical structure of the mandrel through a spring.

Preferably, one end of the clamping groove is provided with a step which can transversely support the flange part.

The utility model discloses formulate main benchmark according to product shape and technological characteristic, through the taut dabber of cylinder, the draw-in groove is propped up to the toper structure, and draw-in groove step face props tight flange part, and the draw-in groove side compresses tightly the flange part. The automatic rotary welding machine has the advantages that the requirement that the flitch and the flange part are tightly attached is met, automatic rotary welding is achieved, the welding seam is uniformly connected and connected, the cylinder clamping groove is loosened after welding is completed, the cylinder clamping groove is automatically contracted under the action of the spring, the part can be easily taken down, and the requirement that the flange part can be automatically compressed or loosened through program control is met. The utility model discloses simple structure is reliable, and it is convenient that the installation is disassembled, has alleviateed operating personnel's intensity of labour greatly, has improved work efficiency, provides the assurance for the automatic unloading of going up of robot.

Detailed Description

In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

The utility model relates to an automatic clamping device when loader flange part welds, as shown in fig. 3, it includes automatic rotary mechanism 3, is equipped with rotary flange 5 and cylinder 4 on the

automatic rotary mechanism

3, and 4 connection dabber 6 of cylinder are equipped with draw-in groove 7 on the 6 other ends of dabber, are equipped with spring 8 on the draw-in groove 7.

Wherein, dabber 6 is formed by the round steel preparation, and 6 one end of dabber is equipped with the screw hole and is connected with the cylinder, and the other end is the toper structure as shown in fig. 4, is equipped with draw-in groove 7 on the dabber 6, and draw-in groove 7 makes up into circular baffle structure by the fan-shaped structure of four quarter circles as shown in fig. 5, and draw-in groove 7 one end is the stair structure can transversely prop flange zero, and the side can vertically compress tightly the flange part as shown in fig. 6.

The utility model discloses application method as follows:

as shown in fig. 7, firstly, the flitch 1 and the flange 2 are respectively placed on the automatic rotating mechanism 3, the program starting cylinder 4 automatically tensions the mandrel 6, the clamping groove 7 is supported under the combined action of the rotating flange 5 and the conical mechanism of the mandrel 6, the clamping groove 7 can transversely support the flange part, the side surface can longitudinally compress the flange part, and the flange part is tightly pasted with the flitch and then welded. After welding, the cylinder 4 is loosened, the clamping groove 7 is contracted under the action of the spring 8, and the part is taken down.

Draw-in groove 7 is clearance fit with flange part 2 under the state of tightening up, and draw-in groove 7 can pass flange part 2 completely, and draw-in groove 7 is interference fit with flange part 2 under the state of strutting, can compress tightly flitch 1 and flange part 2 and make flitch 1 and flange part 2 follow the synchronous rotation of rotary flange 5 under the effect of cylinder 4, reaches the purpose of even linking up welded flange round.
