The base 11 can include a magnetic substance, The magnetic substance refers to a substance which can be magnetized by a magnetic field, such as iron, uranium or nickel' or a compound or mixture thereof. The first clamp 12 is disposed on the base U, wherein the first clamp 12 can be extended upward from the base 11. Preferably, the first clamp 12 is fixed with a detachable spacer 12 For the workpiece to abut. The second clamp 13 is slidably disposed on the base 1 . The second clamp 13 can include a slide seat and a block 13 . The slide seat 201219160 slides off the base 11 , and the block 131 is detachably fixed. In the sliding block, the spacer 131 is located between the sliding seat and the first clamp 12 for the workpiece to abut. Preferably, the two blocks 12 can also include a magnetic substance. A jaw is defined between the clip I2 and the first clamp 13 , and more specifically, the jaw is located between the two blocks 12 ( 3 ) for placing the transposition in the jaw ' The second clamp 13 is pressed against the workpiece. The screw 14 is screwed to the base, and more specifically, is screwed to the protrusion (1). One end of the screw 14 is rotatably disposed on the second clamp 13 and the other end is provided with a grip (4). The screw 14 is provided with a screw lock to drive the second clamp 13 to move relative to the base u so that the sweet mouth is adjustable in size, so that the workpiece can be clamped in the nozzle. The workpiece positioning device 2 for a vise includes a positioning block 2 having a bottom surface 21 and a side surface 212 and a clamping portion 213. The bottom surface 211 and the side surface 212 are each a flat surface, and the bottom surface 2 π is slidably disposed and affixed to the "seat 11" so that the bottom surface 211 can slide relative to the base n, and the side surface can be slidably abutted And flatly attached to the second clip 13 so that the side flaps slip relative to the second gripper 13. The clamping portion 213 and the side surface 212 are respectively arranged on two sides of the positioning block 21, and the clamping portion 213 is configured to abut against the workpiece, so that the vertical block is clamped between the workpiece and the second clamp 13 Wherein the clamping portion may be formed with a stepped groove and an inverted groove 213c, the stepped groove having a vertical plane = a first plane 213a and a second plane coffee, the first plane is parallel, the secret may be located The first plane is taken between the second 13b and the inverted slot 213c is in communication with the stepped slot. The positioning block 201219160 21 includes a magnetic member 22 embedded in the bottom surface 211 of the positioning ghost. More specifically, the positioning block 21 can form a corresponding magnetic member on the bottom surface or other surface. a recess 214 for inserting the magnetic member 22 into the recess 214, wherein the fixing member 22 is fixed to the positioning block 2 by a fixing member 22, and the fixing member 221 is covered by the recess 214. The magnetic member 22 is fixed in the recess 214 without any detachment from other possible embodiments of the present invention, and the magnetic member can be fixed in the positioning block 21 by other fastening means such as tight fitting, gluing or screwing. . According to the above description, the present invention can be used for clamping and fixing a workpiece 3, and a workpiece positioning device 2 is sandwiched between the workpiece 3 and the spacer 131 of the second central clamp 13, and The read-and-position device 2 is interposed between the workpiece 3 and the pad 121 of the first sweetening 12 for the user to screw the screw 14 so that the second sweetener η is pressed toward the first clamp I2 to further the workpiece 3 fixed. Referring to FIG. 4, when the second tong clamp 13 is pressed to the first clamp, the screw Η and the base tolerance are tight, and the second misalignment generates a gap between the second clamp 13 and the base 11 to further drive the gap. The workpiece positioning device 2 red member 3 - and floats upwards, the user can use the tool to strike the workpiece 3 or the jade member positioning device 2, so that the jade member positioning 2 slides relative to the second clamp 13 to make the workpiece positioning device 2 Adjacent to the description of U, as shown in Fig. $, to help accurately position the workpiece 3; preferably, the base ^ and the = sweet 13 or the pad 131 includes a magnetic object f to position the rotation The skirt is placed = the magnetic member 22 has magnetic attraction to the base u and the second button 13 at any time = 201219160 ΓΓΓ 22 can be attached to the base η and the second clip at any time. Between the workpiece positioning device 2 and the second clamp 13 . The stepped groove formed by the workpiece reading device (4) can be continued between the workpiece and the bottom machine for processing the top surface and the side surface of the workpiece 3 to obtain a larger machinable area. Please refer to phase 6, in another embodiment of the invention,

The stepped groove may not be formed in the positioning block 21, so that the top surface of the positioning block 21 and the second clip are directly clamped to the rotation, or refer to FIG. 7, and the height of the positioning device may include several heights. 21, 21, the top surface of the positioning block with a lower secret height forms a stepped groove to hold the workpiece, so that the invention has many different ways of use. In the present embodiment, the miscellaneous pieces of the miscellaneous pieces are magnetically thin, and the magnets or the pieces are directly formed as a fixed detent, and in another embodiment of the invention, the magnetism can be changed. The member is disposed in the pad 131 or the base 11 to make the pad 131 or the base u magnetic. The material of the positioning block 2 includes a magnetic substance, so that the positioning block 2 can be magnetically attracted to the pad 131 and the base 11 at any time. The trend is to achieve the use effect provided by the foregoing embodiments. In other possible embodiments of the present invention, the first sweetness may also be set as a slidable person, and two positioning blocks may be sandwiched between the two clamps, and set in the positioning block or the spacer of the two lost clamps. The magnetic member achieves the use effect provided by the foregoing embodiments. In summary, the invention can be used to place the workpiece positioning device between the vise and the worker 7 201219160. # It can assist the user to precisely position the workpiece, and avoid the workpiece from being moved by the first clamp of the tiger. It can reduce the tolerance generated by machining and improve the machining accuracy. 'The magnetic' / ι system can avoid the arbitrary separation between the fixed tilt and the second pump or the block, and avoid the falling of the machining debris into the gap between the positioning block and the second pinch. In fact, it is a progressive Wei, in line with the patent requirements of the national law, and New Zealand filed a patent application.
