Description

원형의 피가공물 표면연마기{face processing machine of shaft}Circular surface processing machine of shaft

본 발명은 대형선박이나 전동차 등의 구동장치 등과 같은 기계적인 장치에 적용되어 회전마찰에 의해 마모가 발생될 수 있는 원형의 피가공물(축봉)의 표면을 재 가공하기 위한 표면 연마기에 관한 것으로서, 이를 좀더 구체적으로 설명하자면 원형의 피가공물을 신속하게 재 가공할 수 있도록 한 것이다.The present invention relates to a surface polisher for reworking the surface of a circular workpiece (shaft) that can be applied to a mechanical device such as a large ship or a driving device such as an electric vehicle that may be abrasion by rotational friction, More specifically, the circular workpiece can be quickly reworked.

일반적으로 대형선박이나 전동차 구동장치 등의 기구적인 장치에 설치되는 크랭크 축 등과 같은 원형의 피가공물은 일정기간 동안 사용하면 그 표면에 마모가 발생하게 되므로 재 가공(연마)의 필요성이 요구된다.그러나 현재까지 제안되고 있는 재 가공용 연마기는 피가공물에 부착되는 베어링메탈부 등(이하 "부가장치"라 함)을 분해하여야만 피가공물을 투입할 수 있기 때문에 피가공물을 신속하게 재 가공할 수 없게 되고, 그로 인해 가공비 및 인력의 낭비가 컸던 문제점이 있었으며, 또한 피가공물의 표면 가공을 바이트로 하므로 그 가공이 정밀하지 못하였을 뿐만 아니라 바이트의 파손도 쉽게 발생되는 문제점도 있었다.In general, a circular workpiece such as a crankshaft installed in a mechanical device such as a large ship or an electric vehicle driving device is required to be reworked (grinded) because wear occurs on the surface after using it for a certain period of time. The regrind grinder, which has been proposed up to now, cannot be reworked quickly because the work piece can be added only by disassembling the bearing metal part (hereinafter referred to as "additional device") attached to the work piece, Therefore, there was a problem that the waste of processing cost and manpower was great, and also because the surface processing of the workpiece as a bite, the processing was not precise, and there was also a problem that the breakage of the bite easily occurs.

본 발명은 위와 같이 피가공물을 가공기를 이용하여 재 가공함에 있어 나타나는 종래의 문제점들을 해결하기 위함에 그 기술적인 과제를 두고 안출된 것으로서 특히, 피가공물의 투입부가 개폐되도록 하여 피가공물에서 부가장치를 분해하지 않더라도 피가공물을 재 가공할 수 있고, 또 피가공물의 표면 가공을 회전형 가공장치로 할 수 있도록 한 것이다.The present invention has been made in view of the technical problem to solve the conventional problems appearing in the reprocessing of the workpiece using a processing machine as described above, in particular, the input of the workpiece to open and close the additional device in the workpiece The workpiece can be reworked without being disassembled, and the surface of the workpiece can be processed by a rotary processing device.

It consists of both support 23e, 23f which penetrates.

이와 같이 된 본 발명은 반분되는 피동부(2)의 피동스프라켓(21)(21') 절반을 첨부도면 도 4에서와 같이 일측의 회동핀(24)에 의거하여 반 회전시키면 피가공물 (5)이 투입되는 투입부(4)가 개방되게 되고, 이렇게 투입부(4)가 개방되면 원형의 피가공물(5)을 피동부(2)의 측방에서 부터 투입할 수 있게 되어 피가공물(5)에서 부가장치를 분해하지 않더라도 피가공물(5)을 연마공간(28)에 투입할 수 있게되며,According to the present invention, the half of the driven sprocket 21, 21 'of the driven part 2 is half-rotated based on the pivot pin 24 on one side as shown in FIG. The input part 4 to be introduced is opened, and when the input part 4 is opened in this way, the circular workpiece 5 can be introduced from the side of the driven part 2, and the The workpiece 5 can be introduced into the polishing space 28 without disassembling the attachment.

상기와 같이 피가공물(5)의 투입이 완료된 후 회전된 반분 피동스프라켓(21)(21')을 원상복귀 시킴과 동시에 결속부(23)로 나머지 반분 피동스프라켓(21)(21')과 결속시키면 투입된 피가공물(5)은 수개의 클림핑로울러(25)에 의해 지지되고, 이렇게 피가공물(5)이 지지된 상태에서 피동스프라켓(21)(21')과 체인(13)으로 연결된 구동스프라켓(12)을 기동시켜 피동스프라켓(21)(21')을 회전시키면 피동스프라켓(21)(21')에 장치된 연마부(3)의 연마재(31)는 피가공물(5) 외주연을 공전하게 되고, 이때 상기 연마재(31)는 모터(33)에 의해 자전하여 피가공물(5) 표면을 안전하게 가공할 수 있게 된다.상기에서 연마부(3)의 연마재(31) 자전은 그 축이 피동스프라켓(21)(21')에 고정된 모터(33)를 구동시킴으로써 이루어지게 된다. 즉, 모터(33)를 구동시키면 모터(33) 본체는 그 축이 피동스프라켓(21)(21')에 고정되어 있으므로 회전하게 되고, 이와 같이 회전하는 모터(33) 본체는 그 외주연의 보호재(32)와 연마재(31)를 회전시키게 되는데, 상기 보호재(32)는 모터(33) 본체 외면에 감겨져 밀착되어 있기 때문에 모터(33) 본체와 동시회전이 가능하고, 보호재(32) 외면의 연마재(31) 역시 보호재(32) 외면에 감겨져 밀착되어 있으므로 모터(33) 본체와의 동시회전이 가능하게 된다.한편 상기의 결속부(23)는 통상에서와 같이 반분된 피동스프라켓(21)(21')이 첨부도면 도2에서와 같이 닫혀지면 빗장편(23a)은 빗장부(23c)의 양측 지지대(23e)(23f) 사이에 위치되게 되고, 이때 빗장봉(23d)을 빗장편(23a)의 빗장공(23b)에 삽입하여 닫혀진 피동스프라켓(21)(21')의 자연적인 열림(벌어짐)을 방지하게 한다.After the input of the workpiece 5 is completed as described above, the rotated half sprocket 21, 21 'is rotated, and at the same time, the binding portion 23 is engaged with the remaining half sprocket 21, 21'. Then, the inserted workpiece 5 is supported by several crimping rollers 25, and the driving sprocket connected to the driven sprocket 21, 21 'and the chain 13 in the state where the workpiece 5 is supported. When the driven sprockets 21 and 21 'are rotated by activating the 12, the abrasive 31 of the abrasive portion 3 mounted on the driven sprockets 21 and 21' revolves around the outer periphery of the workpiece 5. At this time, the abrasive 31 is rotated by the motor 33 to be able to safely process the surface of the workpiece (5). In the above-described rotation of the abrasive 31 of the abrasive portion 3 is the axis of the driven This is achieved by driving the motor 33 fixed to the sprockets 21 and 21 '. That is, when the motor 33 is driven, the main body of the motor 33 rotates because its shaft is fixed to the driven sprockets 21 and 21 ', and the main body of the rotating motor 33 rotates as the protective material of the outer circumference. The 32 and the abrasive 31 are rotated. Since the protective material 32 is wound around the outer surface of the main body of the motor 33 and is in close contact with the outer surface of the main body of the motor 33, it is possible to co-rotate with the main body of the motor 33. Since 31 is also wound around the outer surface of the protective material 32, it is possible to rotate simultaneously with the main body of the motor 33. On the other hand, the above-mentioned binding portion 23 is divided into the driven sprockets 21 and 21, as usual. ') Is closed as shown in FIG. 2, the clad piece 23a is positioned between the two support members 23e and 23f of the cladding part 23c, and at this time, the cladding bar 23d is connected to the clad piece 23a. Inserted into the bolt hole 23b of the to prevent the natural opening (opening) of the closed sprocket 21 (21 ').

따라서, 본 발명은 상기한 바와 같이 피동스프라켓(21)(21') 절반을 회전시키는 방식으로 개폐시킬 수 있으므로 즉, 피가공물(5) 표면을 재 가공하기 위해 피가공물(5)을 고정하는 고정공간(연마공간)을 개폐시킬 수 있으므로 피가공물(5)에서 부가장치를 분해하지 않더라도 피가공물(5)을 고정공간에 고정시킬 수 있어 피 가공물(5)의 가공시간 및 가공비를 절감할 수 있는 이점이 있고, 이와 아울러 연마부(5)에 원통형의 연마재(31)가 장치되어 있기 때문에 연마부(3)의 파손율이 낮음은 물론 피가공물의 표면을 보다 정밀하게 가공할 수 있어 보다 수명이 오래가는 연매부(3)를 얻을 수 있는 장점도 있는 것이다.Therefore, the present invention can be opened and closed by rotating the half of the driven sprockets 21 and 21 'as described above, that is, fixing the workpiece 5 to rework the surface of the workpiece 5. Since the space (abrasive space) can be opened and closed, the work piece 5 can be fixed in the fixed space even without disassembling the additional device from the work piece 5, thereby reducing the processing time and cost of the work piece 5 In addition, since the cylindrical abrasive 31 is provided in the polishing portion 5, the damage rate of the polishing portion 3 is low, and the surface of the workpiece can be processed more precisely, resulting in a longer service life. There is also an advantage that can be obtained long-lasting part (3).
