Description
Technical Field

[0002] The stator and rotor are the core components of a rotating motor. They work together to achieve energy conversion. The stator is the stationary part of the motor and is usually fixed inside the casing. The rotor is the rotating part of the motor and is located inside the stator.
[0003] The stator core and rotor core are usually made of multiple layers of thin silicon steel sheets. After the silicon steel sheets are stacked, a certain pre-pressure must be applied to them and their height must be measured. During the pre-pressure process, they are usually directly lifted by a lifting cylinder to provide support. The support has poor stability and is prone to retraction when under pressure, affecting the measurement accuracy. At the same time, the lifting cylinder is easily damaged, and the measurement accuracy is difficult to guarantee if the pre-pressure height measurement is performed only by a grating ruler.
[0004] Therefore, there is an urgent need for a high-precision pre-stressing height measuring mechanism for machining stator and rotor cores. Summary of the invention
[0005] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a high-precision pre-compression height measuring mechanism for machining stator and rotor cores.

[0009] Preferably, a rectangular hole for mounting the pillar is vertically opened in the middle of the top of the base, and the bottom of the pillar passes through the rectangular hole and extends to the inside of the slot.
[0010] Preferably, the limiting mechanism includes an insert plate installed in the slot, one end of the insert plate is fixedly installed on the push plate, and the limiting mechanism also includes a push block cylinder fixedly installed on the top of the base plate, and the output end of the push block cylinder is fixedly connected to the push plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. The utility model is a pre-pressure height measuring mechanism for machining stator and rotor cores. A weighing sensor is arranged between the output end of the gas-liquid booster cylinder and the pressure plate, and the pressure plate is fixed on the measuring slide block of the grating ruler. The pressure is measured by the weighing sensor, and the product height is measured by the grating ruler at the same time. Double measures are adopted to ensure the size and position accuracy of the whole product.
[0015] 2. The utility model provides a pre-stressing height measuring mechanism for machining stator and rotor cores. By installing a lifting mechanism and a limiting mechanism under the product tooling, the push block cylinder pushes the slide seat to move along the slide rail through the push rod and the spring, pushes the lifting mechanism outward and moves it to the bottom of the product tooling. After the lifting cylinder lifts the product tooling through the tooling support plate, the push block cylinder continues to push the push plate to move, so that the plug plate is inserted under the pillar. After the lifting cylinder retracts, the plug plate continues to support the pillar to ensure the stability of the bottom of the product tooling during pre-stressing. At the same time, the limit plate continues to compress the spring, which can prevent the lifting mechanism from moving during pre-stressing. During the retraction process, the push block cylinder pulls the lifting mechanism back through the limit plate to achieve reset, and after the plug plate is withdrawn, the tooling support plate automatically falls under the action of gravity. The entire lifting and limiting process does not require manual operation, and the degree of automation is high. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] A slide 10 is installed on the top of the base plate 3.1. The slide 10 is movably connected to the base plate 3.1 through a slide rail 11. The push block cylinder 13.3 pushes the slide 10 along the slide rail 11 through a push rod 13.4 and a spring 13.6, pushes the lifting mechanism 12 outward and moves it to the bottom of the product tooling 2, and the slide 10 extends and retracts by sliding to prevent obstruction of the normal rotation of the rotating disk 1.
[0026] A lifting mechanism 12 for lifting the product tooling 2 is fixedly arranged on the top of the slide 10. The lifting mechanism 12 includes a base 12.1 fixedly installed on the top of the slide 10. A slot 12.2 is opened horizontally through the base 12.1. Lifting cylinders 12.3 are fixedly installed on both sides of the base 12.1. A tooling pallet 12.4 is arranged on the top of the base 12.1. The tooling pallet 12.4 is movably connected with the base 12.1 by plugging through a pillar 12.5 arranged at the bottom.
