Preferably, the telescopic mechanism is an air cylinder. The cylinder is adopted as the telescopic mechanism, the structure is simple, the operation can be fast in place, and the efficiency is improved.

Compared with the prior art, the utility model has the advantages that:

according to the utility model, the turntable is matched with the telescopic mechanism, and after the turntable rotates by a set angle, the blades are forwarded for preliminary spot welding fixation, so that the arrangement quantity of the blades can be easily adjusted according to the requirement. Meanwhile, the magnetic bracket fixes the blade in a magnetic adsorption mode, so that the position of the blade is conveniently adjusted on the bracket, and meanwhile, after the spot welding is fixed, the telescopic mechanism can be directly retracted without additional action of releasing the blade, so that the operation flow is simplified, and the efficiency is improved. Because the blade angle and other dimensional requirements of the guide impeller of the cyclone dust collector are not high, the tool can completely meet the processing requirements of the guide impeller and can meet the processing requirements of the guide impellers with different sizes.

Detailed Description

The utility model is further illustrated, but is not limited, by the following examples.

In embodiment 1, please refer to fig. 1 and 2, a blade welding auxiliary tool for a guide impeller according to the present embodiment is composed of two parts, one is a telescopic mechanism using a cylinder 1 as a main component for pushing a blade 100, and the other is a turntable 3 with a chuck 2 for fixing a hollow axle 101 on which the blade 100 needs to be mounted. Wherein, the cylinder 1 is fixedly installed on the machine 4, the magnetic bracket 5 is fixedly installed at the cylinder rod head end 1a of the cylinder 1, and the magnetic bracket 5 is made to have a shape similar to the blade 100 for adsorbing and supporting the blade 100. The magnetic bracket 5 includes a substrate 51, and a flexible magnetic tape 52 is attached to the surface of the substrate 51 so that the blade 100 is attracted by the magnetic force of the magnetic tape 52. It should be noted that, the telescopic mechanism may also adopt other linear driving mechanisms, such as a hydraulic telescopic rod or an electric cylinder, and in this technical solution, the requirement for telescopic thrust and positioning is not high, so that the cost of adopting the air cylinder 1 as the telescopic mechanism is lower.

The turntable 3 is arranged in front of the expansion and contraction direction of the air cylinder 1, the turntable 3 is provided with a rotation axis which is a second axis b, a tripod chuck 2 is fixedly arranged on the table top of the turntable 3, and the tripod chuck 2 is used for fixing a hollow wheel shaft 101 of the guide impeller. The axis of the tripod chuck 2 is coaxial with the second axis b, and a steering mechanism 6 is further provided, and the steering mechanism 6 drives the turntable 3 to rotate about a first axis a, which is orthogonal to the second axis b. In this embodiment, a five-axis turntable used by a machine tool is adopted, and the five-axis turntable comprises the turntable 3 and the steering mechanism 6.

As shown in fig. 3, the working process of this embodiment is that the cylinder 1 is set to extend and retract in a horizontal direction, so that the five-axis turntable drives the tripod chuck 2 to rotate about the first axis a to the second axis b in a vertical state, then the blade 100 is placed on the magnetic bracket 5, the cylinder 1 is started to extend the cylinder rod forward, the blade 100 is pushed to the side edge of the hollow wheel shaft 101, the mechanical welding arm is used to spot-weld the blade 100 on the hollow wheel shaft 101, then the cylinder 1 is retracted, and the magnetic bracket 5 is separated from the blade 100. The five-axis turntable drives the tripod chuck 2 to rotate by a certain angle (60 degrees is an example of installing six blades 100) by taking the second axis b as an axis, the blades 100 are placed again on the magnetic bracket 5 in the process, the process is repeated until all the blades 100 are fixed on the hollow wheel shaft 101, then the five-axis turntable drives the tripod chuck 2 to rotate by taking the first axis a as an axis until the second axis b is in a horizontal state, and finally a mechanical welding arm welds gaps between all the blades 100 and the hollow wheel shaft 101 to finish the processing of the guide impeller.

In embodiment 2, as shown in fig. 4, the magnetic bracket 5 of the present embodiment is mainly composed of magnetic columns 53, and a plurality of magnetic columns 53 are fixedly installed at the head end 1a of the cylinder rod at intervals, are in a cantilever structure and are arranged at a height, and the magnetic columns 53 arranged at a height adsorb the blade 100 and enable the blade 100 to maintain a certain inclination angle.
