Impeller type casting part correcting mechanism

Technical Field

The utility model relates to the technical field of casting production, in particular to an impeller type casting correcting mechanism.

Background

Because of the impeller of all kinds of centrifugal fans such as waste heat fan, dehumidifying fan because of long-term use under high temperature environment, through the normal maintenance back, still can produce deformation and the dynamic balance maladjustment phenomenon of different degrees, directly lead to the fan to appear the big, noise height, the amount of wind trouble such as little of overall vibration, can't reach normal use effect, also cause certain influence to production.

Because centrifugal forces are generated based on the uneven distribution of mass relative to the axis of any rotor as it rotates about its axis. This unbalanced centrifugal force acting on the rotor bearings will cause vibrations, generate noise and accelerate bearing wear, so that the performance and lifetime of the equipment is seriously affected. In the manufacturing process, rotating parts such as a motor rotor, a machine tool spindle, an internal combustion engine crankshaft, a steam turbine rotor, a gyro rotor, a fan impeller and the like need to be balanced to stably and normally operate.

Therefore, the balancing machine is an indispensable device for reducing vibration, improving performance, and improving quality. The unbalance of the rotor is corrected according to the data measured by the balancing machine, so that the mass distribution of the rotor relative to the axis can be improved, and the vibration generated when the rotor rotates or the vibration force acting on the bearing is reduced to be within an allowable range. Usually, the balancing of the rotor includes two steps of unbalance measurement and correction, the balancing machine is mainly used for unbalance measurement, and the unbalance correction is usually performed by other auxiliary equipment such as a drilling machine, a milling machine and a spot welding machine, or by a manual method. Some balancing machines have made the correction device as part of the balancing machine.

The main drawback of the existing balance correcting device is that the dynamic balance correcting precision is not too high, and the parts with high precision requirements are as follows: the high precision of the motor rotor, the machine tool spindle and the like cannot be implemented, so that the limitation of equipment is caused. Therefore, the industry has improved the device, for example, a centrifugal fan impeller dynamic balance correcting device disclosed in chinese patent, the patent numbers are: 201420802725.8. the device comprises an outer frame (4), and is characterized in that a mandrel (2) is arranged on the outer frame (4), and bearing seats (1) are arranged at two ends of the mandrel (2); a correction base (5) and a base bearing sleeve (6) are arranged at the central position of the bottom of the frame (4), a bearing is arranged on the correction base (5), and a jack is installed on the correction base (5); two planes and two self-aligning bearings are arranged in the base bearing sleeve (6) and are fixed with the bottom of the outer frame (4) through the base bearing sleeve (6).

However, the above solutions have problems: (1) the function of welding is not possessed, and (2) the function of polishing is not possessed. If the impeller needs to be welded or polished, an additional tool needs to be found for operation, which is inconvenient and prolongs the time for correcting the impeller.
