Rubber part freezing trimming device based on 3D (three-dimensional) imaging and work method thereof

Abstract

A rubber part freezing trimming device based on 3D (three-dimensional) imaging comprises a bottom seat, a support leg, a case, a pill spray device, a refrigerating device, a motor frame, a drive motor, a screw rod, a clamp, a 3D imaging system, an upper computer, a cover body and a lifting piston, wherein the cover body and the lifting piston are arranged in the case, the cover body comprises a pill storage layer, a cold storage layer and a spray layer which are sequentially arranged from the outside to the inside, a plurality of inner spray heads and a plurality of outer spray heads are arranged in the spray layer, a first valve is arranged on each inner spray head, a second valve is arranged on each outer spray head, the pill spray device communicates with the pill storage layer througha first hose, the refrigerating device communicates with the cold storage layer through a second hose, the 3D imaging system comprises a 3D camera, a laser probe, a 3D processing module and an imagingmodule, and the upper computer is respectively connected with the 3D imaging system, the drive motor, the pill spray device, the refrigerating device, the lifting piston, the first valves on the plurality of the inner spray heads and the second valves on the plurality of the outer spray heads. The rubber part freezing trimming device based on the 3D imaging significantly improves trimming efficiency of a rubber part.

Description

technical field [0001] The invention relates to the technical field of rubber trimming, in particular to a 3D imaging-based freezing trimming device for rubber parts and a working method thereof. Background technique [0002] Rubber products are widely used in the fields of vibration isolators such as railway transportation, automobiles, wind turbines, marine diesel units, etc., which play a good role in vibration isolation and noise reduction. [0003] The frozen trimming machine is mainly used to replace manual deburring of rubber molded parts, precision injection molding and die-casting products. It is one of the necessary post-processing equipment in the rubber, plastic and die-casting industries. Its working principle is: use the low-temperature freezing effect of liquid nitrogen to embrittle the products made of rubber, plastic or zinc-magnesium-aluminum alloy materials. , by high-speed injection of a polymer particle (ie projectile) to hit the burrs of the product to...

AI Technical Summary

Problems solved by technology

[0005] 1. The rubber parts are in a continuous tumbling state in the drum, which is easy to cause impact damage to the rubber parts;

[0006] 2. Fully spray refrigerant and projectiles in the drum. The refrigerant and projectiles are also sprayed on non-burr areas, such as the rubber body and the drum, resulting in waste of refrigerant and projectiles, and lack of targeted spraying;

[0007] 3. After trimming, it is necessary to warm up the rubber parts, which takes a long time;

[0008] 4. The range of the projectile is longer, the injection force is lower, and the trimming time is longer
