베어링 내·외륜 열처리경도 및 치수검사장치{Bearing inner·outer race heat treatment hardness and dimension inspection apparatus}Bearing inner and outer race heat treatment hardness and dimension inspection apparatus

본 발명은 베어링의 전동체인 볼이나 롤러를 지지하는 내·외륜과 같이 동일한 규격으로 대량생산되는 피측정물의 열처리경도와 내·외경치수를 자동으로 측정하여 양품을 선별할 수 있게 하는 검사장치에 관한 것이다.The present invention relates to an inspection apparatus for automatically selecting the good quality by measuring the heat treatment hardness and the inner and outer diameter of the object to be mass-produced to the same standard, such as the inner and outer rings for supporting the ball or roller of the rolling elements of the bearing will be.

베어링은 범용성의 기계요소부품으로 표준화되어 있어 동일규격의 제품이 대량으로 필요로 하고 있다.Bearings are standardized as general-purpose mechanical component parts, requiring a large number of products of the same standard.

따라서 그 가공이나 조립 등의 생산공정은 대부분이 자동화되어 있다.Therefore, most of the production processes such as processing and assembly are automated.

베어링을 구성하는 구성품 중 전동체인 볼이나 롤러는 전문생산업체에서 생산되어 베어링생산업체의 외주 구매품이므로 자체의 품질검사는 불필요하나, 베어링의 내·외륜은 베어링 제조업체에서 소재를 절단하고 열간단조하여 성형한 후 연마하여 생산하고 있으므로 가공단계별로 철저한 품질검사가 필요하다.Among the components constituting the bearing, the electric chain ball or roller is produced by a specialized manufacturer and is an outsourcing product of the bearing manufacturer. Therefore, its own quality inspection is unnecessary, but the inner and outer rings of the bearing are formed by cutting and hot forging from the bearing manufacturer. Since it is produced after grinding, it is necessary to conduct a thorough quality inspection for each processing step.

종래 베어링 내·외륜에 대한 품질검사는 내·외륜의 내·외경과 같은 치수 검사는 자동화된 장치로 측정하였으나 열처리경도와 같은 검사는 자동화되지 못하여 표본추출하여 수작업으로 검사를 실시하였다.In the conventional quality inspection of the inner and outer rings of the bearing, the dimensional inspections such as the inner and outer diameters of the inner and outer rings were measured by an automated device, but the inspections such as heat treatment hardness were not automated.

따라서 표본검사로 인하여 생산되는 제품 중에 불량품이 혼입될 수 있다는 문제점이 있었다.Therefore, there was a problem that defective products can be mixed in the product produced by the sample inspection.

본 발명은 베어링의 내·외륜에 대한 열처리경도 및 내·외경 치수를 연속적으로 일괄하여 검사할 수 있게 함으로써 검사를 신속하고 정확하게 하여 생산성을 향상할 수 있게 하는 것을 목적으로 한다.An object of the present invention is to be able to continuously inspect the heat treatment hardness and the inner and outer diameter dimensions of the inner and outer rings of the bearing in a lump, so that the inspection can be performed quickly and accurately, thereby improving productivity.

본 발명은 작업대에서 베어링 내·외륜의 외관을 육안검사한 다음, 디로더 앗세이에서 내·외륜을 자동정렬하여 컨베이어로 내·외륜을 이송시켜 트랜스퍼를 이용하여 탈자기로 통과시켜 내·외륜의 자성을 제거한 다음, 퓨셔를 이용하여 내·외륜을 하나씩 차례로 트랜스퍼로 밀어넣어 트랜스퍼는 내·외륜을 열처리경도 검사장치에서 경도검사를 거치게 한 후 불량품을 선별하여 제거하고, 양품은 외경 및 폭을 측정한 후 재차 불량품을 선별한 후 컨베이어를 통하여 정렬대로 이송하여 검사를 종료하게 구성하며, 본 발명의 검사장치는 PLC를 이용하여 자동으로 제어되게 구성한다.The present invention visually inspects the appearance of the inner and outer rings of the bearing on the workbench, and then automatically aligns the inner and outer rings in the deloader assembly to transfer the inner and outer rings to the conveyor to pass through a demagnetizer using a transfer to the magnetic properties of the inner and outer rings. After removing the inner and outer rings into the transfer one by one using a pusher, the transfer allows the inner and outer rings to undergo a hardness test by the heat treatment hardness tester, and then selects and removes the defective parts. After the selection of the defective goods again after the transfer to the alignment unit through the conveyor is configured to end the inspection, the inspection apparatus of the present invention is configured to be automatically controlled using a PLC.

본 발명은 대량으로 생산되는 베어링의 내·외륜을 하나의 통합된 검사장치로 열처리경도와 내·외경치수를 자동으로 검사할 수 있게 하여 신속하고 정확하게 양품을 선별할 수 있어 베어링 생산공정의 생산성을 향상할 수 있게 하는 효과가 있다.The present invention enables to automatically inspect the heat treatment hardness and the inner and outer diameter of the inner and outer rings of the bearing produced in a large amount by one integrated inspection device to quickly and accurately sort the products, thereby improving the productivity of the bearing production process. It has the effect of improving.
