Description

拔卸工具Extraction tool

本發明係涉及一種拆卸用工具；特別是指一種拔卸工具之創新結構型態揭示者，所述拔卸工具用於將一盤形物沿軸向卸離一軸桿。The present invention relates to a tool for disassembly; in particular, it refers to the disclosure of an innovative structure of a pull-out tool. The pull-out tool is used to unload a disk-shaped object from a shaft in the axial direction.

舉凡飛輪、皮帶輪或汽車的碟盤座等盤形物，通常軸設於一軸桿，以汽車用於設置輪圈的該碟盤座為例，該碟盤座與汽車的傳動軸相接，該碟盤座於軸心貫穿一軸孔，該傳動軸具有一軸桿，該軸桿軸入該軸孔。For example, all disk-shaped objects such as flywheels, pulleys, or automobile disc seats, usually the shaft is set on a shaft. The disc seat penetrates a shaft hole in the shaft center, the transmission shaft has a shaft, and the shaft is inserted into the shaft hole.

該碟盤座與該輪圈的結合形態，通常可見有兩種類型，一種類型是該碟盤座貫穿四至六個不等的穿孔，該輪圈靠置於該碟盤座後，利用數根螺栓分別穿過該輪圈與各該穿孔螺接，另一種類型則是該碟盤座設有四至六個不等的螺柱，該輪圈靠置於該碟盤座時，各該螺柱分別穿過該輪圈，再以數個螺帽分別與各該螺柱螺接。The combination of the disc seat and the rim can generally be seen in two types. One type is that the disc seat penetrates four to six perforations. The rim is placed behind the disc seat and uses several The bolts respectively pass through the rim and are bolted to each of the perforations. The other type is that the disc seat is provided with four to six studs. When the rim is placed on the disc seat, each stud Pass through the rim respectively, and then connect to each stud with a plurality of nuts.

習知一種拔卸器可用於將該碟盤座卸離該軸桿，該拔卸器包括一盤體及一推桿，其中該盤體貫穿一螺孔，該推桿螺設於該螺孔，據使該推桿與該盤體沿著軸向相對作動，該盤體環繞該螺孔穿設數個圓形的貫孔，且各該貫孔分別與該螺孔形成等距。A conventional puller can be used to unload the disc seat from the shaft. The puller includes a disc body and a push rod, wherein the disc body penetrates a screw hole, and the push rod is screwed in the screw hole According to the push rod and the disc body move relative to each other along the axial direction, the disc body is provided with a plurality of circular through holes around the screw hole, and each of the through holes is equidistant from the screw hole.

使用該拔卸器將該碟盤座卸離該傳動軸時，首先依據該穿孔或該螺柱的數量，選擇具有相應數量之該貫孔的盤體，並將該盤體靠置於該碟盤座。When using the puller to remove the disc seat from the drive shaft, first select the disc body with the corresponding number of the through holes according to the number of the perforations or the studs, and place the disc body against the disc. Plate seat.

在該碟盤座貫穿該穿孔的場合，各該貫孔分別與各該穿孔相對且連通，而後利用數根螺栓穿過各該貫孔與各該穿孔螺接，且該螺栓的栓頭抵靠著該盤體，而後旋轉該推桿，使該推桿的一端抵靠著該軸桿，並向著該軸桿的方向移動，該盤體即可連動該碟盤座向著遠離該傳動軸的方向移動，待該軸桿相對退出該軸孔，即可完成將該碟盤座卸離該軸桿的操作。When the disc seat penetrates the perforation, each of the through holes is opposite to and communicated with each of the perforations, and then several bolts are used to pass through each of the through holes to be screwed to each of the perforations, and the bolt head of the bolt abuts Hold the disc body, and then rotate the push rod so that one end of the push rod abuts against the shaft and moves in the direction of the shaft. The disc body can then move the disc seat in a direction away from the drive shaft. After moving, when the shaft is relatively withdrawn from the shaft hole, the operation of removing the disc seat from the shaft can be completed.

在該碟盤座設有數個該螺柱的場合，該盤體靠置於該碟盤座時，使各該螺柱分別穿樞各該貫孔，數個螺帽分別與各該螺柱螺接，且該螺帽抵靠著該盤體，而後旋轉該推桿，使該推桿的一端抵靠著該軸桿，該盤體連動該碟盤座向著遠離該傳動軸的方向移動，據此完成將碟盤座卸離該傳動軸的操作；為便於說明，該碟盤座用於定位設置該輪圈的該貫孔及該螺柱，於后以定位結構代稱。In the case where the disc seat is provided with several studs, when the disc body is placed against the disc seat, each of the studs is pivoted through each of the through holes, and several nuts are connected to each of the studs. Connect, and the nut abuts against the disc body, and then rotate the push rod so that one end of the push rod abuts against the shaft rod, the disc body moves the disc seat in a direction away from the drive shaft, according to This completes the operation of unloading the disc seat from the drive shaft; for ease of description, the disc seat is used to locate the through hole and the stud of the rim, which will be referred to as a positioning structure hereinafter.

查，該拔卸器於實際應用經驗中發現仍舊存在下述問題與缺弊：該盤體所形成該貫孔的數量及各該貫孔的相對配置，可滿足操作卸離具有相應數量之該定位結構的碟盤座的需要，但是，不同規格的該碟盤座，該定位結構的數量亦有所不同，就提供小型汽車設置的該碟盤座而言，該定位結構的數量通常為四至六個不等，雖習見有可應用於卸離具有四個或五個之該定位結構的碟盤座之拔卸器，亦見有可應用於卸離具有四個或六個之該定位結構的碟盤座之拔卸器，卻未見具備可應用於卸離具有四個或五個或六個之該定位結構的碟盤座之拔卸器，其原因在於，該盤體若需配合四至六個不等的該定位結構，穿設相應的該貫孔時，某些該貫孔將發生連通現象，使得該栓頭或該螺帽無法與該盤體形成有效的抵靠，操作該推桿時，該盤體受力不均衡而產生作動偏斜現象，無法有效地卸離該碟盤座或使碟盤座因偏斜而產生變形，甚至可能造成該軸孔與該軸桿發生干涉現象而導致形狀破壞問題。According to the investigation, the puller still has the following problems and shortcomings in the practical application experience: the number of through holes formed by the disc body and the relative configuration of the through holes can satisfy the requirements for operation and removal of the corresponding number of through holes. However, the number of positioning structures is different for the disc holders of different specifications. For the disc holders provided for small cars, the number of positioning structures is usually four to There are six sizes, although there are conventional pullers that can be used to remove the disc holders with four or five positioning structures, and there are also pullers that can be used to remove four or six positioning structures. The puller for the disc holder of, but there is no puller that can be used to remove the disc holder with four or five or six positioning structures. The reason is that if the disc body needs to be matched For the positioning structure ranging from four to six, when the corresponding through hole is penetrated, some of the through holes will be connected, so that the bolt head or the nut cannot form an effective abutment with the plate body, and the pusher is operated. When lever, the disc body is unbalanced in force, resulting in actuation deflection, which cannot be effectively removed from the disc seat or deforms the disc seat due to the deflection, and may even cause interference between the shaft hole and the shaft. Phenomenon leads to the problem of shape destruction.
