본 고안은 농용 트랙터의 작업기 부착기구인 3점 지지장치의 하부 링크에 관한 것으로, 특히 단순한 공정에 의하여 제작될 수 있는 동시에, 견고하고 경제적인 제품 생산을 할 수 있도록 고안된 하부 링크에 관한 것이다.The present invention relates to a lower link of a three-point support device, which is a work attachment device for a farm tractor, and more particularly, to a lower link designed to be manufactured by a simple process and to produce a solid and economical product.
일반적으로, 농용 트랙터의 작업기 부착기구인 3점 지지장치에는 2개의 하부 링크와 1개의 상부 링크로 구성되어 각종 잡업기을 연결하여 사용할 수 있도록 되어 있다.In general, a three-point support device, which is a work attachment device for a farm tractor, includes two lower links and one upper link so as to connect and use various work machines.
그러나 상기 3점 지지장치에서 과중량의 작업기를 연결 상용하면 용접부의 결함으로 인하여 하부 링크가 부러지는 사례가 빈번하여 하부 링크는 물론 작업기가 파손되는 결과를 초래 하였다.However, when the heavy work machine is connected and used in the three-point support device, the lower link is frequently broken due to defects in the welding part, resulting in damage to the lower link as well as the work machine.
이러한 문제점을 다시 설명하면, 종래의 하부링크(11)는 제4도 및 제5도에 도시한 바와 같이, 평강판을 사용한 연결대(12) 양단으로 단조된 링크(13)(13')를 용접하여 융착시킨 다음, 링크(13)(13')의 부싱자리에 부싱(14)(14')을 끼워 넣고 부싱 삽입구를 스웨징(Swaging)함으로서 형성되는 것이므로, 연결대(12)와 링크(13)(13')간의 용접된 유착부위(15)(15')가 취약하여 과중량의 작업기를 사용하면 부러지는 결점이 있었던 것이며, 한편으로는 비교적 제작 공정이 많고, 이로 인하여 원가 상승 요인이 되는 문제점이 있었던 것이다.To describe this problem again, the conventional lower link 11 welds the forged links 13 and 13 'to both ends of the connecting table 12 using flat steel plates, as shown in FIGS. 4 and 5. By fusion, and then insert the bushings 14 and 14 'into the bushing seats of the links 13 and 13', and swaging the bushing insertion holes. Welded joints (15 ') between (13') were fragile and there was a drawback when using an overweight working machine. On the other hand, there were relatively many manufacturing processes, which caused cost increase. This was there.
따라서 본 출원인은 이와 같은 제 결점을 해소하기 위하여 연구를 거듭한 끝에 용접 부위가 없으며, 제작공정이 간단한 하부링크를 개발하기에 이르른 것으로, 본 고안의 목적은 취약지점 즉, 용접부위가 없는 단일체의 몸체로 형성된 하부링크를 제공하는데 있다.Therefore, the present applicant has continued to research the above-mentioned defects, and there is no welding site, and the manufacturing process has led to the development of a simple lower link. The object of the present invention is to provide a weak point, that is, a single body without a welding site. To provide a lower link formed of a body.
본 고안의 또다른 목적은, 제작 공정이 간단한 하부링크를 제공함으로써 원가 절감을 기하려는데 있다.Another object of the present invention is to reduce the cost by providing a simple lower link manufacturing process.
위의 목적들을 달성할 수 있는 본 고안의 특징적인 구성은, 단일체의 평판재로 구성된 하부링크의 몸체 양측에 부싱 조립 부위를 삽공형상으로 가공한 후 부싱을 조립한 다음 스웨징함으로써 이룩되는 것으로, 이른 첨부된 도면과 관련하여 더욱 상세히 설명하면 다음과 같다.The characteristic configuration of the present invention that can achieve the above objects is achieved by inserting the bushing assembly after the bushing assembly site on both sides of the body of the lower link consisting of a single plate material, and then swaging, More detailed description with reference to the accompanying drawings as follows.
도면에서(1)은 본 고안의 하부링크로서, 평판재로 형성된 몸체(1a)의 양측으로는 각각 절곡된 동일체의 링크부(1b)(1b')를 형성한다.In the drawing (1) is a lower link of the present invention, both sides of the body (1a) formed of a plate member forms a link portion (1b) (1b ') of the same bent, respectively.
그리고 제3(a)도에 도시한 바와 같이 링크부(1b)(1b')에 삽공 형상의 삽입구(2)(2')를 형성한 다음, 그 둘레에 스웨징을 할 수 있도록 환홈(3)를 요설하여 스웨징부(4)(4')를 형성토록 한다.Then, as shown in FIG. 3 (a), an insertion hole 2, 2 'having an insertion hole shape is formed in the link portions 1b and 1b', and then the annular groove 3 can be swung around it. ) To form swaging portions 4 and 4 '.
다음, 제3(b)도에 도시한 바와 같이 링크부(1a)(1a')에 형성된 삽공형상의 삽입구(2)(2')에 부싱(5)(5')을 삽입한 다음, 스웨징부(4)(4')를 내측으로 절곡하여 삽입구(2)(2')를 축소시키면 부싱(5)(5')은 삽공형상의 삽입구(2)(2')내에서 이탈 되지 않게 됨으로서 1개의 하부링크(1)가 완성되는 것이다.Next, as shown in FIG. 3 (b), the bushings 5 and 5 'are inserted into the insertion holes 2 and 2' of the insertion hole formed in the link portions 1a and 1a ', When the recesses 4, 4 'are bent inward to reduce the insertion holes 2 and 2', the bushings 5 and 5 'are not separated from the insertion holes 2 and 2'. One lower link 1 is completed.
따라서, 이와 같이 구성되는 본 고안의 하부링크(1)는 제1도에 도시한 바와 같이 트랙터(6)의 후미에 1개의 상부링크(7)와 함께 3점 지지장치가 구성되는 것으로, 상기 상부링크(7)와 하부링크(1)(1')에는 각종 작업기가 연결 사용된다.Accordingly, the lower link 1 of the present invention, which is configured as described above, has a three-point support device together with one upper link 7 at the rear of the tractor 6, as shown in FIG. (7) and the lower link (1) (1 ') is used to connect various work machines.
이와 같이 사용되는 본 고안의 하부링크(1)는 하부링크(1) 몸체(1a)가 링크부(1b)(1b')와 단일체로 형성되어 있음으로서 과중량의 작업기를 사용 하더라도 절대로 부러지는 사례가 발생하지 않게 된다.The lower link 1 of the present invention used as described above is a case in which the lower link 1 body 1a is formed in a single body with the link parts 1b and 1b 'so that it never breaks even when an overweight working machine is used. Will not occur.
즉, 종래의 하부링크(11)에서와 같이 용접부위(15)(15')의 결함으로 작업기의 작업중에 발생하는 파손을 방지할 수 가 있게 되는 것이다.That is, as in the conventional lower link 11, it is possible to prevent breakage occurring during the operation of the work machine due to defects in the welding areas 15 and 15 '.
한편 본 고안의 하부링크(1)는 제작 과정에서 종래에 사용하던 링크(13)(13')부의 단조 및 열처리 과정이 제거 됨과 아울러, 용접부위(15)(15')가 제거 됨으로서 그 형상이 단순화 됨은 물론, 이로 인해 결제적인 제품 생산을 할수가 있는 것이다.On the other hand, the lower link 1 of the present invention is removed from the forging and heat treatment process of the link 13, 13 'portion used in the conventional manufacturing process, and the shape of the lower link (1, 15') is removed by removing. Not only is it simplified, but it also makes it possible to produce payment products.
이상에서와 같이 본 고안에 의하면, 트랙터(6)의 3점 지지장치중 작업기를 견인, 또는 상하로 조정하는 하부링크(1)를 종래에 비해 용접부위를 제거 함으로써 작업기 작업중 하부링크(1)가 파손되는 것을 방지 할 수 있으며, 그 제작 공정을 감소 시킴으로써 원가절감을 기할수 있는 효과가 있는 고안이다.As described above, according to the present invention, the lower link 1 during the work machine operation is removed by removing the welded portion of the lower link 1 which pulls or adjusts the work machine up or down in the three-point support device of the tractor 6. It is designed to prevent damage and to reduce cost by reducing the manufacturing process.
