Clamp suitable for hoisting motor stators of different sizes

Abstract

The invention relates to a clamp suitable for hoisting motor stators of different sizes. A thread on the outer edge of a lead screw below a lifting lug is provided with a rotation block in an engagement rotation manner. A lower connecting rod installing block is arranged at the lower end of the lead screw. The rotating block and the lower connecting rod installing block are provided with a plurality of telescopic connecting rods in the radial direction of the lead screw. A vertical clamping plate is arranged at the end portion of the outer side of each telescopic connecting rod. The outer edge of the part, between the rotating block and the lower connecting rod installing block, of the lead screw is sleeved with a spring. According to the clamp, an adjusting block rotates, an upper connecting rod installing block is pushed downwards and pushes the telescopic connecting rods, the clamping plate extends to the outer sides and clamps the inner edge of an iron core, and the clamping plate stably ejects the inner edge of the iron core. A rubber pad installed on the outer side end face of the clamping plate can adapt to hook face changes of different parts of the inner edge of the iron core, and therefore hoisting of iron cores of different sizes can be achieved, the work efficiency is greatly improved, and the purchasing cost is reduced for manufacturers.

Description

technical field [0001] The invention belongs to the technical field of improving the structure of a motor stator core transport and assembly jig, in particular to a jig suitable for hoisting motor stators of different sizes. Background technique [0002] The motor is a common power equipment. Its structure is mainly composed of a casing, a rotor and a stator. The stator is fixed to the casing, and the rotor rotates at high speed in the magnetic field generated by the power delivered by the external power supply to realize the drive of pumps and other equipment. The stator in the above-mentioned motor includes an iron core and multiple windings. The windings are installed on the iron core according to certain requirements.

Problems solved by technology

The stator in the above-mentioned motor includes an iron core and multiple windings. The windings are installed on the iron core according to certain requirements. Since the inner wall of the iron core will be processed into a groove shape, and the iron core itself is punched from silicon steel plates and then stacked. , so the hoisting hole cannot be directly processed on the iron core, which makes it very inconvenient to hoist the iron core. Some manufacturers use some special structure clamps during the stator transportation and assembly process through structural research. core, and then hang it on the hook of the crane through the lifting hole or lug on the fixture, and the crane can be lifted and moved to realize the transportation and assembly of the iron core

In actual use, it is found that due to the difference in the power of the motor, the size of the iron core has many specifications, which requires the manufacturer to be equipped with fixtures of different specifications, resulting in an increase in procurement costs and inconvenient production.
