搪孔治具Pupil fixture

本發明係與治具有關，特別是有關於一種搪孔治具。 The invention is related to the treatment, in particular to a pupil fixture.

車床加工的過程中，工件旋轉的軸心與刀把中心是否同心影響加工品質甚鉅。 During the lathe processing, whether the axis of the workpiece rotation and the center of the tool holder are concentrically affect the processing quality.

然而習知的校正同心方式為製作一精密治具，再以該治具為基準，利用測量儀器例如千分表反覆量測及微調刀具直到達到要求，另外，市售刀具雖有特定尺寸，但由於加工公差或預留裕度，刀具之外徑或夾刀套筒之內孔徑不一定可完全符合，因此通常需要再對夾刀套筒之內孔進行某程度上的搪孔。因此，治具成本較高且校正同心度及搪孔所需的工時較長。 However, the conventional method of correcting concentricity is to make a precision jig. Based on the jig, the measuring instrument such as a dial gauge is used to repeatedly measure and fine-tune the tool until the requirement is met. In addition, although the commercially available tool has a specific size, Due to machining tolerances or allowances, the outer diameter of the tool or the inner diameter of the cutter sleeve may not be fully compliant, so it is usually necessary to perform a certain degree of boring of the inner bore of the squeegee sleeve. Therefore, the cost of the jig is high and the man-hours required to correct the concentricity and the pupil are longer.

因此，有必要提供一種新穎且具有進步性之搪孔治具，以解決上述之問題。 Therefore, it is necessary to provide a novel and progressive boring jig to solve the above problems.

本發明之主要目的在於提供一種搪孔治具，可快速搪孔、快速達到刀具及工件同心，安裝容易且成本低。 The main object of the present invention is to provide a boring jig that can quickly boring, quickly reach the concentricity of the tool and the workpiece, and is easy to install and low in cost.

為達成上述目的，本發明提供一種搪孔治具，供裝配於一車床之一旋轉座，該旋轉座具有一旋轉軸心，該車床另包括一於該旋轉軸心上與該旋轉座相對之固定座，該固定座供固定一刀具，該搪孔治具包括：一固定頭，供固接於該旋轉座並繞該旋轉軸心轉動；一插設端，開設一供該刀具插設之斜孔，該斜孔具有一延伸方向；其中，當該固定頭固接於該旋轉座時，該延伸方向與該旋轉軸心之間形成一大於零之傾斜夾角。 In order to achieve the above object, the present invention provides a boring jig for mounting on a rotating seat of a lathe, the rotating base having a rotating shaft center, the lathe further including a rotating shaft opposite to the rotating base a fixing seat for fixing a cutter, the boring fixture comprising: a fixing head for Fixed to the rotating base and rotates around the rotating shaft; a plugging end, a beveled hole for inserting the cutter, the inclined hole has an extending direction; wherein when the fixing head is fixed to the rotating base The extending direction forms a tilt angle greater than zero between the extending direction and the rotating axis.

請參考圖1至4，其顯示本發明之一較佳實施例，本發明之搪孔治具1包括一固定頭10及一插設端20。 Referring to FIGS. 1 through 4, there is shown a preferred embodiment of the present invention. The boring jig 1 of the present invention includes a fixed head 10 and an insertion end 20.

該搪孔治具1供裝配於一車床之一旋轉座31，該旋轉座31具有一旋轉軸心311，該車床另包括一於該旋轉軸心311上與該旋轉座31相對之固定座32，該固定座32供例如以一夾刀套筒33來固定一刀具40；該固定頭10供固接(例如夾固)於該旋轉座31並繞該旋轉軸心311轉動；該插設端20開設一供該刀具40插設之斜孔21，該斜孔21具有一延伸方向211，該延伸方向211較佳與該旋轉軸心311位於同一平面，可減少旋轉時徑向上震動，提高加工品質；該固定頭10固接於該旋轉座31時，該延伸方向211與該旋轉軸心311之間形成一大於零之傾斜夾角θ。藉此，該車床運轉時該搪孔治具1可帶動該刀具40繞該旋轉軸心311轉動，進而可在該夾刀套筒33搪出一與該旋轉軸心311同心之內孔321，再將該搪孔治具1取下，將工件夾持於該旋轉座31，且將選用之刀具結合至該夾刀套筒33，可快速搪孔且使得該夾刀套筒33夾持(例如以鎖件徑向穿設固定)之各式刀具與該旋轉座31上的工件有較佳的同心度。該傾斜夾角θ決定搪孔後之該內孔321直徑。該傾斜夾角θ較佳是不大於5度，例如不大於3度，使該刀具40搪孔時不致於因轉擺幅度過大而斷損。 The boring jig 1 is mounted on a rotating seat 31 of a lathe, the rotating base 31 has a rotating shaft 311, and the lathe further includes a fixing base 32 opposite to the rotating base 31 on the rotating shaft 311. The fixing base 32 is configured to fix a cutter 40 by, for example, a clamping sleeve 33; the fixing head 10 is fixed (eg, clamped) to the rotating base 31 and rotates around the rotating shaft 311; the insertion end 20 is provided with a slanting hole 21 for inserting the tool 40. The slanting hole 21 has an extending direction 211. The extending direction 211 is preferably in the same plane as the rotating axis 311, which can reduce the radial vibration during rotation and improve processing. When the fixing head 10 is fixed to the rotating base 31, the extending direction 211 and the rotating shaft center 311 form a tilt angle θ greater than zero. Thereby, the boring jig 1 can drive the cutter 40 to rotate around the rotating shaft 311 during the operation of the lathe. An inner hole 321 which is concentric with the rotating shaft center 311 can be pulled out from the clamping sleeve 33, and the boring jig 1 can be removed to clamp the workpiece to the rotating base 31, and the selected tool is used. In combination with the cutter sleeve 33, the various cutters that can be quickly bored and clamped (for example, radially inserted by the lock member) and the workpiece on the rotary seat 31 are preferably Concentricity. The inclination angle θ determines the diameter of the inner hole 321 after the pupil. The inclination angle θ is preferably not more than 5 degrees, for example, not more than 3 degrees, so that the cutter 40 is not broken due to excessive swing width.

該固定頭10內部設有一空室11。該空室11較佳係朝遠離該插設端20之方向漸擴。該空室11與該斜孔21連通且於該固定頭10之相對該插設端20之一端開放。本實施例中該空室11呈圓筒狀並朝遠離該插設端20之方向錐狀漸擴，且該空室11之徑向尺寸大於該斜孔21之徑向尺寸，藉此該空室11可容許該刀具40插設時依需求調整插設深度。藉由錐狀漸擴，該空室11提供該刀具40插設空間的同時還可保有夾持處些微夾持變形。該空室11與該斜孔21之連接處設有一肩部111，該肩部111在該車床夾持該搪孔治具1時可軸向內縮，夾持效果更佳。 The fixed head 10 is internally provided with an empty chamber 11. The empty chamber 11 preferably tapers away from the insertion end 20. The empty chamber 11 communicates with the inclined hole 21 and is open at one end of the fixed head 10 opposite to the insertion end 20. In this embodiment, the empty chamber 11 has a cylindrical shape and tapers in a direction away from the insertion end 20, and the radial dimension of the empty chamber 11 is larger than the radial dimension of the inclined hole 21, thereby The chamber 11 can allow the insertion depth of the tool 40 to be adjusted as needed. By the tapered divergence, the empty chamber 11 provides the space for inserting the cutter 40 while retaining some slight clamping deformation at the grip. A joint portion 111 is formed at the junction of the empty chamber 11 and the inclined hole 21, and the shoulder portion 111 is axially retractable when the lathe jig 1 is clamped by the lathe, and the clamping effect is better.

本實施例中，該搪孔治具1另包括一連接於該固定頭10與該插設端20之間的大徑徑向凸緣12、且另包括一連接於該大徑徑向凸緣12與該插設端20之間的小徑徑向凸緣13。較詳細地說，該大徑徑向凸緣12徑向凸出於該固定頭10，該小徑徑向凸緣13徑向凸出於該插設端20，該大徑徑向凸緣12使得該搪孔治具1夾持於該車床上時可在軸向上抵靠定位。該小徑徑向凸緣13(該大徑徑向凸緣12與該插設端20交接處為受力最大處)可補強該搪孔治具1使用時的徑向承受能力，避免破壞及減少形變。 In this embodiment, the boring jig 1 further includes a large diameter radial flange 12 connected between the fixing head 10 and the insertion end 20, and further includes a radial flange connected to the large diameter. A small diameter radial flange 13 between the 12 and the insertion end 20. In more detail, the large diameter radial flange 12 projects radially from the fixed head 10, and the small diameter radial flange 13 projects radially from the insertion end 20, the large diameter radial flange 12 When the boring jig 1 is clamped on the lathe, it can be positioned in the axial direction. The small-diameter radial flange 13 (the portion where the large-diameter radial flange 12 and the insertion end 20 meet the maximum force) can reinforce the radial bearing capacity of the boring jig 1 to avoid damage and Reduce deformation.

該插設端20另徑向地設有至少一連通該斜孔21之鎖孔22，至少一鎖件23鎖設於該至少一鎖孔22並可伸入該斜孔21。該插設端20之外表面24設有至少一沿該固定頭10至該插設端20方向延伸之平面25。本實施例中，該外表面24設有相對二該平面25，該插設端20於其中一該平面25徑向地設有複數連通該斜孔 21之該鎖孔22，複數該鎖件23分別鎖設於該複數鎖孔22並可伸入該斜孔21。藉由該複數鎖件23伸入該斜孔21，可徑向抵緊該刀具40使得該刀具40在該延伸方向211上的位置固定並與該搪孔治具1不相對旋轉。該二平面25可使該複數鎖孔22易於加工，且固緊效果更佳。 The insertion end 20 is further provided with at least one locking hole 22 communicating with the inclined hole 21, and at least one locking member 23 is locked to the at least one locking hole 22 and can extend into the inclined hole 21. The outer surface 24 of the insertion end 20 is provided with at least one plane 25 extending in the direction of the fixing head 10 to the insertion end 20.
