Abstract
Description
本發明係與自行車的花鼓有關有關;特別是指一種花鼓的去毛邊方法。The present invention is related to the hub of a bicycle; in particular, it refers to a method of deburring the hub.
自行車的花鼓是用以固定車輪的輻條,作為車輪的轉動中心。一般製作花鼓的方式,係使用CNC加工機對一工件進行加工,以得到花鼓粗胚,花鼓粗胚的邊緣處會存在著毛邊。因此,必需再對花鼓粗胚進行去毛邊作業,以去除邊緣上的毛邊,得到花鼓之成品。The hub of a bicycle is used to fix the spokes of the wheel as the center of rotation of the wheel. The general way of making hubs is to use a CNC machining machine to process a workpiece to obtain the hub's rough embryo. There will be burrs on the edge of the hub's rough embryo. Therefore, it is necessary to deburr the rough embryo of the hub to remove the burrs on the edges and obtain the finished hub.
習用的去毛邊作業是人員手持花鼓粗胚,或以夾具夾持花鼓粗胚,再手持夾具。接著人員以花鼓粗胚的邊緣接觸砂輪機的砂輪,並因應花鼓粗胚的邊緣形狀移動花鼓粗胚,以高速轉動的砂輪去除邊緣上的毛邊。由於是採用人工去毛邊,因此,不同人員對於去毛邊作業的熟練度各不相同,導至產能無法有效提升。再者,人員手持花鼓粗胚就砂輪機時,若有持拿不穩的情形,輕則造成花鼓粗胚掉落,重則時有人員受傷的情形發生。The customary deburring operation is to hold the rough embryo of the hub in hand, or hold the rough embryo of the hub with a jig, and then hold the jig. Then, the staff touched the grinding wheel of the grinder with the edge of the hub rough embryo, and moved the hub rough embryo according to the shape of the hub rough embryo, and removed the burrs on the edge with the grinding wheel rotating at high speed. Due to the manual deburring, different personnel have different proficiency in the deburring operation, resulting in the production capacity cannot be effectively improved. In addition, when personnel hold the rough hub of the grinder while holding the grinder, if the holding is unstable, the rough hub of the hub may fall off in the slightest, and the person may be injured from time to time.
是以,習用的自行車花鼓去毛邊之作業仍未臻完善,尚有待改進之處。Therefore, the conventional bicycle hub deburring operation is still not perfect and needs improvement.
有鑑於此,本發明之目的在於提供一種自行車之花鼓的去毛邊方法,可辨識出加工的起始位置,並進行去毛邊作業。In view of this, the object of the present invention is to provide a method for deburring a bicycle hub, which can identify the starting position of processing and perform deburring operations.
緣以達成上述目的,本發明提供的一種刀夾裝置包括有下列步驟:In order to achieve the above object, a tool holder device provided by the present invention includes the following steps:
提供一花鼓粗胚,該花鼓粗胚具有多個幅條座沿該花鼓粗胚的不同徑向排列;該些幅條座包括一定位幅條座,該定位幅條座上設置有一個定位凸塊;A hub thick embryo is provided, the hub crude embryo has a plurality of spoke seats arranged along different radial directions of the hub crude embryo; the spoke seats include a positioning spoke seat, and the positioning spoke seat is provided with a positioning protrusion Piece;
透過一治具固定該花鼓粗胚,並將該花鼓粗胚移動到一預定加工位置;Fix the hub rough embryo through a jig, and move the hub rough embryo to a predetermined processing position;
由一影像辨識裝置擷取該花鼓粗胚的影像,並辨識該定位凸塊,以得到該定位幅條座之位置;An image recognition device captures an image of the hub rough embryo and recognizes the positioning bump to obtain the position of the positioning spoke seat;
依據該定位幅條座之位置移動該花鼓粗胚,使用一刀具自該定位幅條座開始去除毛邊,並去除該定位凸塊;以及Move the hub rough embryo according to the position of the positioning spoke base, use a cutter to remove burrs from the positioning spoke base, and remove the positioning protrusion; and
以該刀具繼續去除該花鼓粗胚其它位置之毛邊,以形成一花鼓。Use the tool to continue to remove the burrs in other positions of the hub rough embryo to form a hub.
本發明之效果在於,藉由在定位幅條座上設置定位凸塊,即可讓影像辨識裝置辨識出定位幅條座,以作為去毛邊加工的起始位置,有效提升去毛邊作業的效率。The effect of the present invention is that by providing positioning protrusions on the positioning spoke base, the image recognition device can recognize the positioning spoke base as the starting position of the deburring processing, thereby effectively improving the efficiency of the deburring operation.

本實施例中,其中該定位幅條座18包括二側面182與一外端面184,各該側面182與一該幅條座16相鄰,該外端面184連接於該二側面182之間且面向該花鼓粗胚10之一端的一外側。該定位凸塊20往側向延伸至超過其中一該側面182的延伸面。該定位凸塊20係連接於其中一該側面182上。更詳而言,該外端面184與其中一該側面182具有一交界邊緣18a,定位凸塊20與交界邊緣18a相連。實務上,該定位凸塊20亦可位在鄰近該交界邊緣18a處,而未與交界邊緣18a相連。In this embodiment, the
透過加工機的一治具300穿入該花鼓粗胚10之本體12的軸孔122,且治具300抵接於軸孔122之孔壁,以固定該花鼓粗胚10。並且將該花鼓粗胚10移動到一預定加工位置。在此步驟中所使用的加工機可以是CNC加工機或機械手臂。A
請配合圖7與圖8,使用一影像辨識裝置500擷取該花鼓粗胚10的影像,並辨識該定位凸塊20,以得到該定位幅條座18之位置。本實施例中,該影像辨識裝置500係自該花鼓粗胚10之一端的外側擷取該花鼓粗胚10的影像。該影像辨識裝置500包括一光源模組502、一攝影模組504及一處理模組506,光源模組502用以發出光線至該花鼓粗胚10,攝影模組504取得花鼓粗胚10之一端的影像並傳送到處理模組506,處理模組506由所接收的影像辨識該些幅條座16之外輪廓,並在辨識任一該幅條座16的外輪廓具有往側向延伸的定位凸塊20之外輪廓時,則判斷為該定位幅條座18。Please cooperate with FIG. 7 and FIG. 8 to use an
續參圖8,加工機依據該定位幅條座18之位置,移動該花鼓粗胚10,使該定位幅條座18對應去除毛邊的一刀具400,使用該刀具400自該定位幅條座18開始去除毛邊,並去除該定位凸塊20。本實施例中,加工機移動該花鼓粗胚10使定位凸塊20對應於刀具400,先去除該定位凸塊20,再去除該定位幅條座18其它部位的毛邊。Continuing to refer to Figure 8, the processing machine moves the hub
接著再以該刀具400繼續去除該花鼓粗胚10其它位置之毛邊,直到所有的毛邊去除完成,藉此,形成圖9所示之無毛邊的花鼓30。Then, the
圖10、圖11為花鼓粗胚之定位幅條座的其它實施態樣,其中,圖10中,定位凸塊40係連接於定位幅條座18的側面182及外端面184上。圖11中,定位凸塊42係連接於定位幅條座18的外端面184,並且往側向延伸超過側面182的延伸面。藉此,影像辨識裝置皆可藉由在圖10、圖11中凸出的定位凸塊40, 42辨識出定位幅條座18。10 and 11 show other implementations of the positioning spoke seat of the hub rough embryo. In FIG. 10, the
據上所述,本發明自行車之花鼓的去毛邊方法,藉由在定位幅條座上設置定位凸塊,即可讓影像辨識裝置辨識出定位幅條座,以作為去毛邊加工的起始位置,達到以加工機自動化去毛邊之目的。更值得一提的是,由於可以確認加工的起始位置,因此,可有效避免花鼓粗胚與刀具發生預期外的碰撞,造成損壞。實務上,定位塊亦可在定位幅條座上的其它位置,重要的是讓影像辨識裝置可以辨識出定位凸塊。According to the above, the method for deburring the hub of a bicycle of the present invention, by providing positioning bumps on the positioning spoke base, the image recognition device can identify the positioning spoke base as the starting position for deburring processing , To achieve the purpose of automatically removing burrs with processing machines. What's more worth mentioning is that since the starting position of the machining can be confirmed, it can effectively avoid the unexpected collision of the hub rough embryo and the tool, causing damage. In practice, the positioning block can also be located at other positions on the positioning spoke base. It is important that the image recognition device can identify the positioning bump.
