刻度筒110具有一第一刻度標記111及一第一外螺紋部112。The scale cylinder 110 has a first scale mark 111 and a first external thread portion 112.

手轉筒120是以轉動之方式套設於刻度筒110之上。更詳細的來說,如第2圖、第3圖及第4圖所示,手轉筒120具有一第一內螺紋部121、一第二內螺紋部122、一第二刻度標記123、一內凸緣124及複數個防滑槽125。在此,手轉筒120之第一內螺紋部121乃是嚙合於刻度筒110之第一外螺紋部112, 因而可使得手轉筒120以轉動之方式套設於刻度筒110之上。此外,如第2圖所示,當手轉筒120以轉動之方式套設於刻度筒110之上時,手轉筒120是滑動於刻度筒110之第一刻度標記111之上,以及手轉筒120之第二刻度標記123是對應於刻度筒110之第一刻度標記111。另外,在本實施例之中,內凸緣124是成型於手轉筒120之內部之中,並且內凸緣124是位於第一內螺紋部121與第二內螺紋部122之間。此外,防滑槽125是成型於手轉筒120之外部上,其可用來在轉動操作時提供適當之摩擦效果。The hand drum 120 is sleeved on the scale cylinder 110 in a rotating manner. More specifically, as shown in FIG. 2, FIG. 3, and FIG. 4, the hand drum 120 has a first internal thread portion 121, a second internal thread portion 122, and a second scale mark 123, Inner flange 124 and a plurality of anti-slip grooves 125. Here, the first internal thread portion 121 of the hand drum 120 is engaged with the first external thread portion 112 of the scale drum 110, Therefore, the hand drum 120 can be sleeved on the scale cylinder 110 in a rotating manner. In addition, as shown in FIG. 2, when the hand drum 120 is sleeved on the scale drum 110 in a rotating manner, the hand drum 120 is slid over the first scale mark 111 of the scale drum 110, and the hand The second scale mark 123 of the drum 120 is the first scale mark 111 corresponding to the scale drum 110. Further, in the present embodiment, the inner flange 124 is formed in the interior of the hand drum 120, and the inner flange 124 is located between the first female thread portion 121 and the second female thread portion 122. In addition, the anti-slip groove 125 is formed on the outside of the hand drum 120, which can be used to provide a proper friction effect during the turning operation.

如第4圖所示,連接桿130是穿設於刻度筒110及手轉筒120之中,並且連接桿130具有一第一端部131及一第二端部132。在此,第一端部131是相對於第二端部132,並且第一端部131是突出於刻度筒110之一端。此外,第二端部132是抵接於手轉筒120內之內凸緣124。As shown in FIG. 4, the connecting rod 130 is disposed in the scale cylinder 110 and the hand drum 120, and the connecting rod 130 has a first end portion 131 and a second end portion 132. Here, the first end portion 131 is opposite to the second end portion 132, and the first end portion 131 is protruded from one end of the scale drum 110. Additionally, the second end 132 is abutted within the inner flange 124 within the hand drum 120.

如第2圖、第3圖及第4圖所示,後蓋140是連接於手轉筒120,並且後蓋140具有一第二外螺紋部141。在此,如第4圖所示,手轉筒120之第二內螺紋部122乃是嚙合於後蓋140之第二外螺紋部141。此外,值得注意的是,當後蓋140連接於手轉筒120時,連接桿130之第二端部132乃是抵接於手轉筒120內之內凸緣124與後蓋140之間。As shown in FIGS. 2, 3, and 4, the rear cover 140 is coupled to the hand drum 120, and the rear cover 140 has a second male thread portion 141. Here, as shown in FIG. 4, the second internal thread portion 122 of the hand cylinder 120 is the second male thread portion 141 that is engaged with the rear cover 140. In addition, it should be noted that when the rear cover 140 is coupled to the hand drum 120, the second end 132 of the connecting rod 130 abuts between the inner flange 124 and the rear cover 140 in the hand drum 120.

如第2圖及第4圖所示,複數個量測條150是以對稱之方式連接於刻度筒110與連接桿130之第一端部131之間。在此,每一個量測條150具有一轉動端151、一滑動端152、一長透孔153及一錐形部154。轉動端151是相對於滑動端152,並且轉動端151是以轉動之方式連接於連接桿130之第一端部131。 滑動端152是以滑動之方式連接於刻度筒110。長透孔153是成型於滑動端152之上。更具體而言,每一個第一插銷160是穿設於每一個量測條150之轉動端151以及連接桿130之第一端部131之中,如此一來,每一個量測條150之轉動端151即可相對於連接桿130之第一端部131轉動。在另一方面,每一個第二插銷170是穿設於每一個量測條150之長透孔153及刻度筒110之中,如此一來,每一個量測條150之滑動端152即可相對於刻度筒110滑動(亦即,第二插銷170是滑動於長透孔153之中)。此外,錐形部154是成型於轉動端151與滑動端152之間。As shown in FIGS. 2 and 4, a plurality of measuring strips 150 are connected in a symmetrical manner between the scale cylinder 110 and the first end 131 of the connecting rod 130. Here, each of the measuring strips 150 has a rotating end 151, a sliding end 152, a long through hole 153 and a tapered portion 154. The rotating end 151 is opposite to the sliding end 152, and the rotating end 151 is rotatably coupled to the first end 131 of the connecting rod 130. The sliding end 152 is slidably coupled to the scale drum 110. The long through hole 153 is formed over the sliding end 152. More specifically, each of the first pins 160 is disposed in the rotating end 151 of each of the measuring strips 150 and the first end portion 131 of the connecting rod 130, so that the rotation of each measuring strip 150 The end 151 is rotatable relative to the first end 131 of the connecting rod 130. On the other hand, each of the second pins 170 is disposed in the long through hole 153 and the scale tube 110 of each of the measuring strips 150, so that the sliding end 152 of each measuring strip 150 can be opposite. The scale drum 110 slides (that is, the second plug 170 slides into the long through hole 153). Further, the tapered portion 154 is formed between the rotating end 151 and the sliding end 152.

如上所述,當手轉筒120相對於刻度筒110轉動時,手轉筒120便會驅使連接桿130相對於刻度筒110移動(因為連接桿130之第二端部132是抵接於手轉筒120內之內凸緣124與後蓋140之間),因而會迫使每一個量測條150相對於連接桿130之第一端部131轉動以及相對於刻度筒110滑動。As described above, when the hand drum 120 rotates relative to the scale drum 110, the hand drum 120 will drive the connecting rod 130 to move relative to the scale drum 110 (because the second end 132 of the connecting rod 130 abuts the hand turn) The inner flange 124 and the rear cover 140 in the barrel 120, thereby forcing each of the measuring strips 150 to rotate relative to the first end 131 of the connecting rod 130 and to slide relative to the scale cylinder 110.

接下來說明以錐形孔量測裝置100量測一錐形孔之角度尺寸的運作方式。Next, the operation of measuring the angular size of a tapered hole by the tapered hole measuring device 100 will be described.

首先,如第5圖所示,將錐形孔量測裝置100對準插入至一錐形孔T之中。接著,如第6圖所示,錐形孔量測裝置100之複數個量測條150之錐形部154會先初步地抵接於錐形孔T之內壁。此時,量測條150是位於一初始狀態下。在此,L代表第二插銷170至連接桿130之垂直距離,X1代表第一插銷160至第二插銷170之水平距離,以及θ1代表量測條150與連接桿130之間的夾角。在此,L、X1及θ1係為已知的數值。First, as shown in Fig. 5, the tapered hole measuring device 100 is aligned and inserted into a tapered hole T. Next, as shown in FIG. 6, the tapered portion 154 of the plurality of measuring strips 150 of the tapered hole measuring device 100 firstly abuts against the inner wall of the tapered hole T. At this time, the measuring bar 150 is in an initial state. Here, L represents the vertical distance of the second pin 170 to the connecting rod 130, X1 represents the horizontal distance of the first pin 160 to the second pin 170, and θ1 represents the angle between the measuring bar 150 and the connecting rod 130. Here, L, X1 and θ1 are known values.

接著,如第7圖所示,手轉筒120可相對於刻度筒 110轉動而驅使連接桿130相對於刻度筒110移動,直到得量測條150之錐形部154完全貼合於錐形孔T之內壁為止。此時,第一插銷160至第二插銷170之水平距離已變為X2,以及量測條150與連接桿130之間的夾角已變為θ2。在此,θ2亦為錐形孔T之內壁與連接桿130之間的夾角。同時,如第8圖所示,第一插銷160至第二插銷170之水平距離的移動值是由Δ所表示。在此,Δ之數值可以由手轉筒120在刻度筒110之第一刻度標記111上的移動數值而得知(亦即,藉由精確量測第一刻度標記111與第二刻度標記123之相對變化而得知)。然後,根據三角函數關係即可以得到以下的關係式:Tanθ2=L/X2=L/(X1-Δ)。Next, as shown in FIG. 7, the hand drum 120 can be opposite to the scale drum The rotation of 110 drives the connecting rod 130 to move relative to the scale cylinder 110 until the tapered portion 154 of the measuring strip 150 completely conforms to the inner wall of the tapered hole T. At this time, the horizontal distance from the first pin 160 to the second pin 170 has become X2, and the angle between the measuring bar 150 and the connecting rod 130 has become θ2. Here, θ2 is also an angle between the inner wall of the tapered hole T and the connecting rod 130. Meanwhile, as shown in FIG. 8, the movement value of the horizontal distance from the first pin 160 to the second pin 170 is represented by Δ. Here, the value of Δ can be known from the movement value of the hand drum 120 on the first scale mark 111 of the scale drum 110 (that is, by accurately measuring the first scale mark 111 and the second scale mark) I learned about the relative change of 123). Then, according to the trigonometric function relationship, the following relational expression can be obtained: Tan θ2 = L / X2 = L / (X1 - Δ).

亦即,θ2=arcTan(L/(X1-Δ))。That is, θ2 = arcTan (L / (X1 - Δ)).

由於L、X1係為已知的數值以及Δ也可以經由刻度筒110之第一刻度標記111被量測得知,故θ2之數值便可以經由θ2=arcTan(L/(X1-Δ))之關係式而獲得。最後,由於錐形孔T之角度是兩邊對稱的,故錐形孔T之角度尺寸即為兩倍的θ2(亦即,2×θ2)。Since L and X1 are known values and Δ can also be measured via the first scale mark 111 of the scale cylinder 110, the value of θ2 can be θ2=arcTan(L/(X1-Δ)). Obtained by the relationship. Finally, since the angle of the tapered hole T is bilaterally symmetrical, the angular dimension of the tapered hole T is twice θ2 (i.e., 2 × θ2).

如上所述,藉由本發明所揭露之錐形孔量測裝置100,任何錐形孔之角度尺寸即可輕易與精確地被獲得,因而可以大幅降低產品製造之時間與成本。As described above, with the tapered hole measuring device 100 disclosed in the present invention, the angular dimension of any tapered hole can be easily and accurately obtained, thereby greatly reducing the time and cost of product manufacture.
