본 고안은 핀으로 연결된 작동부위의 마모방지구에 관한 것으로, 더욱 상세하게는 굴삭기 등의 아암선단부에 착탈가능하게 장착되는 버킷의 배면고정부위에서와 같이 핀으로 연결되는 작동부위에 외부압에 의한 핀과 보스의 마모됨을 방지하기 위해 삽입된 부싱이 보스 내부로 이탈됨을 방지하기 위해 부싱사이에 스페이서를 설치하고 핀에 형성된 윤활유 주입공에 의해 핀과 부싱 접촉면에 그리이스 등이 원활하게 공급되어 핀과 부싱의 표면긁힘 및 마모됨을 방지할 수 있도록 한 것에 관한 것이다.The present invention relates to the wear protection of the operating part connected to the pin, and more particularly to the operation part connected to the pin by the external pressure on the rear fixing part of the bucket detachably mounted to the arm tip of the excavator, etc. To prevent the pin and the boss from being worn out, the spacer is installed between the bushings to prevent the inserted bushing from escaping into the boss, and grease is smoothly supplied to the pin and the bushing contact surface by a lubricating oil hole formed in the pin. To prevent surface scratches and wear of the bushing.

핀으로 연결된 힌지부위에서 외부압에 의해 핀과 보스이 마모됨을 방지하기 위해 보스내부에 부싱을 삽입설치할 때에 제1도의 (a)에 도시된 바와같이, 보스(1) 내부로 부싱(2)의 이탈됨을 방지하기 위해 부싱(2)이 삽입되는 보스(1)의 내측에 걸림턱(3)을 형성하여야 하는 기계기공상의 불편함과, 부싱(2)으로부터 핀(4)의 원활한 착탈동작이 가능하고 이들의 마모됨을 방지하기 위해 핀(4)과 부싱(2) 접촉면에 그리이스 등의 윤활제를 주기적으로 주입하기 위해서는 제1도의 (b)에 도시된 바와같이, 부싱(2)과 보스(1)에 그리이스 주입공(5)(6)을 형성하고 부싱(2) 내주면에 주입되는 그리이스의 일부가 일시 잔류되도록 글루우브(gloove) 홈(7)을 형성해야 되므로 이러한 부싱의 제작이 곤란하고, 상기 글루우브홈(7)에 의해 부싱(2)에 착탈되는 핀(4) 외주연에 흠집이 발생하여 핀(4)과 부싱(2)의 조기마모현상을 초래하는 것이었다.When the bushing is inserted into the boss to prevent the pin and the boss from being worn by the external pressure at the hinge portion connected by the pin, the bushing 2 is separated into the boss 1, as shown in FIG. In order to prevent the mechanical pore of forming a catching jaw (3) inside the boss (1) into which the bushing (2) is inserted to prevent the possibility, and smooth detachable operation of the pin (4) from the bushing (2) In order to periodically inject lubricants such as grease into the contact surfaces of the pins 4 and the bushings 2 to prevent their wear, the bushings 2 and the bosses 1, as shown in FIG. It is difficult to manufacture such a bushing because a groove groove 7 must be formed so that the grease injection holes 5 and 6 are formed and a part of the grease injected into the bushing 2 inner circumferential surface remains temporarily. Scratches on the outer circumference of the pin 4 detachable from the bushing 2 by the groove groove 7 This resulted in premature wear of the pin (4) and bushing (2).

본 고안은 상기와 같은 종래기술의 문제점을 감안하여 안출한 것으로, 본 고안의 목적은 핀으로 연결된 힌지부위에 삽입된 부싱의 이탈됨을 방지하기 위해 부싱사이에 스페이서를 삽입하여 부싱의 기계기공공정을 줄여 대량생산이 가능하여 이의 가격을 낮출 수 있는 핀으로 연결된 작동부위의 마모방지구를 제공하는데 있는 것이다.The present invention is conceived in view of the problems of the prior art as described above, the object of the present invention is to insert a spacer between the bushings to prevent the bushing inserted into the hinge portion connected by a pin to the mechanical pore process of the bushing It is to provide wear protection of the working part connected with pins, which can be reduced and mass production is possible, thereby lowering its price.

본 고안의 다른목적은 부싱에 삽입되는 핀에 그리이스 주입공을 형성하여 핀과 부싱의 착탈시 이들의 접촉으로 인한 흠집 및 마모됨을 방지하여 핀과 부싱의 내구수명을 연장시킬 수 있도록 한 핀으로 연결된 작동부위의 마모방지구를 제공하는데 있는 것이다.Another object of the present invention is to form a grease injection hole in a pin inserted into the bushing to prevent scratches and abrasion due to contact between the pin and the bushing, thereby extending the endurance life of the pin and the bushing. The purpose is to provide wear protection for the working area.

상기와 같은 목적을 달성하기 위한 본 고안의 특징은 핀으로 연결된 힌지연결부의 마모됨을 방지하기 위해 보스에 부싱과 핀이 결합되는 것에 있어서, 상기 부싱(2)(2')이 보스(1) 내부로 이탈됨을 방지하기 위해 부싱(2)(2')사이에 스페이서(8)를 삽입하고, 부싱(2)(2')에 삽입되는 핀(4)에 그리이스 주입용 니플(11)(12)이 형성된 것이다.Features of the present invention for achieving the above object is that the bushing and the pin is coupled to the boss to prevent wear of the hinge connection portion connected by the pin, the bushing (2) (2 ') is inside the boss (1) A spacer 8 is inserted between the bushings 2 and 2 'in order to prevent deviation from the grease, and the grease injection nipples 11 and 12 are inserted into the pins 4 inserted into the bushings 2 and 2'. Is formed.

이하, 본 고안에 의한 핀으로 연결된 작동부위의 마모방지구를 첨부도면을 참조하여 구체적으로 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, the wear protection port of the operating part connected by the pin according to the present invention will be described in detail.

제2도는 본 고안에 의한 마모방지구에 관한 도면으로 (a)는 마모방지구의 결합상태도이고, (b)는 부싱에 결합되는 핀의 단면도로서, 핀으로 연결된 힌지연결부의 마모됨을 방지하기 위해 삽입되는 부싱과 핀이 결합되는 것에 있어서, 상기 보스(1)에 삽입된 부싱(2)(2')이 보스(1) 내부로 자리이탈됨을 방지하기 위해 대향되는 보스(2)(2') 사이에 스페이서(8)를 삽입설치하고, 상기 부싱(2)(2')이 보스(1)외부방향으로 이탈됨을 방지하기 위해 스토퍼(9)(10)가 부싱(2)(2')외측면에 체결되며, 상기 부싱(2)(2')에 삽입되는 핀(4) 양단부에 그리이스 주입용 니플(11)(12)이 설치되고, 니플(11)(12)로 부터 주입되는 그리이스가 핀(4)과 부싱(2)(2')의 접촉면에 주입되도록 상기 니플(11)(12)과 연통되는 그리이스 통과공(13)(14)이 핀(4)에 원주방향으로 형성되며, 상기 통과공(13)(14)과 연통되는 글루우브 홈(15)(16)이 핀(4)외주연에 형성된 것이다.2 is a view of the wear protection device according to the present invention (a) is a state of engagement of the wear protection device, (b) is a cross-sectional view of the pin coupled to the bushing, inserted to prevent wear of the hinge connection connected by the pin In which the bushing and the pin are coupled, between the bosses 2 and 2 'which are inserted into the boss 1 so as to prevent the bushing 2 and 2' from being displaced into the boss 1. The spacer 8 is inserted into the stopper, and the stoppers 9 and 10 have an outer surface of the bushings 2 and 2 'to prevent the bushings 2 and 2' from escaping outward of the boss 1. Grease injection nipples 11 and 12 are installed at both ends of the pins 4 inserted into the bushings 2 and 2 ', and greases injected from the nipples 11 and 12 are pins. Grease through holes 13 and 14 communicating with the nipples 11 and 12 are formed in the circumferential direction in the pin 4 so as to be injected into the contact surface between the 4 and the bushings 2 and 2 '. With the through hole (13) (14) Glue probe groove 15 that is cylindrical (16) is formed on the outer periphery of the pins (4).

이상에서와 같이 본 고안에 의한 핀으로 연결된 작동부위의 마모방지구는 보스에 결합되는 부싱과 핀의 상호 마모됨을 방지하기 위해 보스에 삽입되는 대향되는 부싱사이에 스페이서를 삽입설치하여 부싱의 위치이동됨을 방지함으로써 부싱의 구조를 간단하게 하여 기계기공에 소요되는 시간을 단축하여 이의 제조가격을 낮추어 제품의 경쟁력을 높이고, 부싱과 핀의 접촉면에 주입되는 그리이스 등의 윤활제 주입공을 핀에 형성함으로써 부싱에 핀의 착탈시 부싱과 핀의 접촉에 의한 긁힘 및 마모됨을 방지하여 핀과 부싱의 수명을 연장시켜 이들의 신뢰도를 높일 수 있는 잇점을 갖게 되는 것이다.As described above, the wear protection tool of the operating part connected with the pin according to the present invention is installed by inserting a spacer between the bushing coupled to the boss and the opposite bushing inserted into the boss to prevent mutual wear of the pin. By simplifying the structure of the bushing, it reduces the time required for mechanical pore, lowers its manufacturing price, enhances the competitiveness of the product, and forms a lubricant injection hole such as grease injected into the contact surface between the bushing and the pin on the pin. When the pins are attached and detached, the scratches and wear caused by the contact between the bushings and the pins are prevented, thereby extending the life of the pins and the bushings, thereby increasing their reliability.
