Description of the invention: [Technical field to which the invention pertains] In particular, a clamping device for clamping a workpiece according to the invention with respect to a clamping bore is provided. [Prior Art] During the machining or measurement operation, the workpiece or the workpiece to be measured is clamped/U will be processed first or the amount (4) accuracy. 4 & will directly affect the subsequent clamping of a workpiece that is clamped through its hole for top positioning and mandrel positioning. α private? As shown in Fig. 1, the top-to-top method is achieved by the two ejector pins 2 abutting against the ends of the hole of the workpiece 1, respectively, in the first method. The defect of the reading method is that the hole of the workpiece 1 is a through hole or the workpiece 1: two opposite coaxial holes, and secondly, the method is often caused by the lead angle of the hole on the workpiece being too small or the workpiece being tilted due to the center height of the two thimbles 2 . The result of the double is as shown in Fig. 2. The mandrel positioning method is to perform the clamping positioning by inserting the mandrel 4 matching the hole of the workpiece 1 into the hole. The drawback of this method is that the aperture is larger or smaller due to processing variations of the holes of the workpiece 1. When the aperture is small, the material is not _ manhole towel; when the New (four) is large, the mandrel field*

In the present month, the axial displacement device drives the radial direction (four) of the sliding block by the axial movement of the sliding bar, so that the sliding (four) can cooperate with the fixed shaft to control the loss of the workpiece. The clamping of the workpiece can be easily accomplished by controlling the movement of the slider along the sleeve. [Embodiment] Referring to FIG. 3, a preferred embodiment of the clamping device of the present invention includes a button 10, a handle 20, a spring 30, a sliding bar 4G, a τ-shaped boundary block 50, a support plate 60, and A fixed shaft 7〇. The button 1 is in the shape of a truncated cone. It includes a cylindrical portion 12 and a threaded post M extending from the free end of the cylindrical portion r. The handle 2 〇 is in the shape of a truncated cone. The side is provided with a non-slip pattern, and its center is along the axis. The through hole 22 is provided with a three-amp boring hole around the through hole 22 . . . . The sliding strip 4 〇 includes - a rectangular strip 42 and a wedge block 44 extending from the side of the square bar 42 - at the 42-end end of the rectangular strip. : A screw hole 46 is formed (see Fig. 5). The upper surface of the molded block is a bevel! The width of the rectangular strip 42 is wider than that of the wedge block 44. The T-shaped slide block 50 includes a transverse plate portion 52 and a front plate portion 54 extending from the horizontal plate portion η. The two sides of the horizontal plate portion 52. The vertical plate portion 54 is provided with a mounting hole 56, and the lower surface of the vertical plate portion is a sloped surface, and the width of the vertical plate portion 54 is the same as that of the sliding block 4〇. The fixed shaft 70 includes a rotating portion. 72. A κ n solid mortise portion 76 and a dam portion 74 located between the rotating portion 2 and the fixing portion 76. The fixed shaft 7 〇 at the axial center of the yoke and the yoke shaft 70 defines a rectangular groove 78. The 折 Α 折 76 76 76 is obtained by cutting the wrong material into a cylinder. After cutting the material, two beveled faces are formed, and each of the beveled faces 762 is opened - a avoidance groove 764, and the fixed portion is in two avoidance grooves (10) = open - long The length of the hole 766 is longer than that of the shape of the sliding block. The slot 768 is defined in the fixing portion 76. The slot, the slot 2 and the hole 766 are connected. The width of the slot 78 is wider. Slots are provided. A three-threaded hole 722 is defined in the free end of the rotating portion 72 (see Fig. 5). The support plate 60 is a square plate for defining the spatial position of the fixed axicon, and can be fixedly coupled to the processing machine. Or a detecting machine, a shaft hole 62 is opened at the center thereof. Referring to FIG. 4 to FIG. 6, when assembling, the rotating portion 72 of the fixed shaft 7〇 is inserted into the shaft hole 62 of the supporting plate 60, and the three screws (9) are used. The three mounting holes 24 passing through the handle 20 and the three screws of the rotating portion 72 of the fixed shaft 7 are clamped to the fixing wire 7'' so that the branching plate 6G is caught on the handle 74 and the blocking portion 74 of the fixed shaft 70. The rotating portion of the fixed shaft 7〇 is rotatably mounted in the shaft hole 62 of the support plate 60; the end opposite to the wedge block 44 of the slide bar 4〇 is inserted into the rectangular groove of the fixed shaft 70 by the fixing portion 76-end. 78, the Asian wedge member 44 enters the slot 768 of the fixing portion 76; the spring 3 〇 = the through hole 22 of the handle 20 is sleeved to the sliding bar 4 〇, through the button (10) = column 14 cooperates with the screw hole 46 of the sliding bar 4〇 to fix the button 1〇 to the 7th moving bar 40. The two ends of the spring 30 respectively abut against the button 10 and the fixed button 10 can be under the constraint of the spring 3〇 The through hole 伸 of the handle is inserted into the handle; * The longitudinal plate portion M of the T-shaped sliding block 5 插入 is inserted into the slot of the fixed shaft 7 担 90 through the hole 766 of the fixed shaft 70 and the θ-shaped sliding block. 'The interference pin 9〇 and the mounting hole 56 have an interference fit. Under the action, the stop pin 90 can move up and down in the hole 766. When using the button 1G, the spring 3G is compressed, and the sliding bar 4 is twisted: 10 "moving to the right" T-shaped sliding block 5 〇 under the action of gravity or with the inclined surface of the wedge-shaped block which makes the τ-shaped sliding block 5 〇 along the sliding strip 4〇: the T-shaped sliding block 5 〇 and the fixed shaft 7 The fixed portion 7 of the cymbal "and the geometric profile of the human 7 is reduced" can be used to fix the workpiece 1 along the axial direction of the hole; the fixing portion 76 of the ϊ, release the button 1 〇, 弹 3 〇 = 30 push 'sliding bar 4 〇 and button 丨. The sliding direction of the wedge-shaped block along the sliding strip 4〇 is relatively upward-sliding. The geometrical wheel of the workpiece 1 combined with the fixing portion 76 of the fixed shaft 70 is tightened to complete the automatic positioning and clamping. . Rotation = The fixed shaft 70 can be used to drive the workpiece 1 to rotate. In other embodiments, the anti-slip pattern on the rotary shank 2G is replaced by a gear, which can be driven by a motor. In addition, the spring 3G can be used by other elastic member hydraulic devices or the like. ~ Such as pore pressure, 1326337 == description 'The invention meets the requirements of the invention patent, 提出laws filed according to law.
