[Prior Art] According to the working machine of a milling machine or a CNC machining center, etc., it is necessary to set a reference plane before the front to make the machining accuracy more precise. In addition, the edge finder is used to measure the reference plane, and the edge finder has improved the progressive effect over the period of time. For example, the public beginning ^ & 々 A. No. 458846 "Three-axis datum measuring device" invention patent case, which is to set up a light source and related power supply in the measurement, and the state, and the sides of the measuring device The top side of the dome is provided with an inductive body to allow the _ 7 ' to form a conductive loop between the 疋 state and the working machine when the tool contacts one of the inductors, so that the illuminating source is illuminated, so that the last one is Under the disassembly tool, the workpiece reference surface can be measured in the two-axis [or three-dimensional] direction. However, the above-mentioned citations have many components, and the cost is high. In addition, because each "and" After a slight re-induction, I am afraid that due to the contraction and stretching of the elastic force..." I will leave some measurement displacement, and the concern that the reference surface measurement coordinate position will be lost to zero, if I have not returned to the zero point, I don’t know. It has been returned to the next measurement to increase the error value to accuracy. [New content] In view of the above problems, the creator further aims to provide a three-dimensional edge finder for research and development. Therefore, the simple structure of the present invention achieves the measurement work, and the main system does not require technical precision. Any reference plane in the direction, that is, the M311515 ί measurement, also maintains a three-point coplanar stability, so that the measurement immediately after the measurement 'for the measurement accuracy will not be lost. In order to achieve the purpose of the description, the technical means used in the present invention is to provide a three-dimensional edge finder, which comprises: a cover seat which is hollow; - a balance seat mounted in the cover seat a disk portion, a column portion extending axially from a central portion of the disk portion, the disk portion equally extending three actuation posts around the column portion, the column portion further detachably inserting a detecting component, the disk portion Surface mounting - elastically recovering the original (4) reading the detecting element offset (4) sensor; a base for engaging the cover seat, which is hollow, for the detecting element to extend beyond the base 'the base has a horizontal The top surface of the top surface corresponding to each of the touch columns respectively forms a concave-shaped, -, and three measuring slots, whereby the first, second, and third measuring slots and each of the sensing columns respectively have three different directions contact. Therefore, according to the technical means of this creation, the brief descriptions of the functions that can be obtained by this creation are as follows: 1. The structure of this creation is very simple, and there is no need to emphasize precise assembly technology. This is the use of the touch column to make the point contact surface. In order to contact the first, second and second measuring slots, it is possible to have good offset sensitivity at the time of measurement, so that the contact offset of the detecting element is sensitively transmitted to the sensor to obtain the coordinate value of the measuring reference surface. . 2. Because of the detection component and the three touch columns, the creation has four points. When measuring, the detection element will maintain the steady state of the contact surface of the measuring groove of the contact surface of the sensing element and the other two touch column. There is no possibility of loss of movement in the measurement and measurement errors. 3, the first two advantages, after the completion of the creation of the measurement, the three touch columns immediately weight M311515. One, two, three-dimensional touch surface of the first and second measuring grooves, to ensure that the balance seat back to the original position 'accurately and instantly return Return to zero state, returning to zero accuracy will not leave any errors and differences, and keep every measurement accurate. [Embodiment] This creation is a three-dimensional edge finder, as shown in the first figure, which shows that the creation has a shackle (10), a base (3 〇) connected under the cover 〇〇), a column portion (23) extending from the base (30), and a detecting member (25) is extended at the center of the column portion (23) so that the detecting head (2 51) of the detecting member (25) can contact the workpiece (6) 〇) The benchmark is 10 faces. Please refer to the first, second and third figures. The cover (1〇) is hollow, and the inner side is sequentially formed with a first hole (丨丨) and one hole larger than the first hole (1 work). a second hole (12), a third hole (13) having a larger aperture than the second hole (12), the third hole (13) forming an internal thread on the inner side (13〇, and in the second hole (12) An elastic member (14) is mounted, which can be a spring. A balance seat (2〇) mounted in the cover seat (10) has a disk portion (21) and a central axial extension from the disk portion (21) a column portion (23), wherein the disk portion (21) equally extends three touch columns (22) around the column portion (23), and the column portion (23) is recessed from the end surface with a rod groove (24). The detecting element (25) is inserted into the rod groove (24), and a round-shaped detecting head (251) is formed at the end, so after the detecting element (25) is inserted into the rod groove (24), the screw is transmitted ( 241) screwed outside the column portion (23) against the positioning detecting member (25) to prevent the detecting member (25) from falling out of the balance seat (2〇), and the balance seat (2〇) in the disk portion (21) The top surface is equipped with a detection detection element (25) The offset sensor (26) is inductively connected to the working device by the elastic member (14) through the first hole (11), so that the elastic member (14) is sleeved. Surrounding the outside of the inductor (26), the two ends of the elastic member (14) are respectively pressed against the radial surface of the disk portion (21) and the second hole (12) 7 M311515. 'The base (30) is Hollow seat shape, the top surface (31) is a horizontal plane, the inner shape is formed into an inner hole (32), and the inner hole (32) corresponds to and communicates with the bottom end surface of the base (30) to form a perforation (321) having a small aperture. When the balance seat (2〇) is placed on the base (3〇), the column portion (23) and the detecting element (25) are extended through the perforations (321), and the outer side of the base (33) is provided with a corresponding squat (ίο) The thread (33) is threadedly engaged with the internal thread (131), so that the base (30) and the cover seat (1〇) are combined, and the top surface (31) corresponds to the touch column (22), respectively forming a concave shape The first, second and third measuring slots (34) (35) (36) are used by the first, second and third measuring slots (34) (35) (3 6 ) for the actuating posts of the balancing seat (20) ( 22) Insert I and touch to make the base (3 〇 ) assume the balance seat (2 〇), each of the touch columns (2 2) are arc-shaped end faces to maintain contact with them in point contact; and the first, second and third measuring slots (34) (35) (36) For the shape, please refer to the second, fifth, and figure. The middle of the measuring slot (3 4) is the inner conical surface, one side is a one-dimensional contact surface (40), and the second measuring groove (35) is an inner oblique cone. The surface is different from the first measuring groove (34) on the different side of the two-dimensional contact surface (41), and the difference between the first and second-dimensional contact surfaces (4〇) (41) is similar to the difference between the X and Y axes, and the third The measuring groove (36) has a groove shape with a flat inner surface, and the inner bottom surface is a three-dimensional contact surface (43), so that the one-dimensional and two-dimensional contact surfaces (4〇) (4) are similar to the X, the Υ axis, and the three-dimensional contact surface ( 43) Similar to the x-axis direction, so that the contacts forming the three-axis direction can be contacted by the touch column (2 2). When the creation is performed, as shown in the third and seventh figures, after the sensor (26) is activated, the detection head (2 51 ) of the creation is used, for example, when the top side of the workpiece (5 〇) is touched, The piece (25) is subjected to the pressure of being touched upward, so the pressure is transferred to the trigger post (22) of the corresponding third measuring groove (36) of the balance seat (20), so that the touch column (22) is detached from the upper part. The three-dimensional contact surface (43) presses the elastic member (丨4) upward, so the sensor (26) receives the offset and offset information of the balance seat (2〇), and sends the detected message to 8 M311515. The associated control device displays the coordinates of its reference plane. After the measurement, as soon as the detecting element (2 5 ) is removed, the disk portion (21) of the balance seat (2〇) is pressed by the restoring force of the elastic member (14), and the respective sensing posts of the balance seat (20) are driven ( 22) Return to the first, second and third measuring slots (34) (35) (36), and touch the state of each of the first, second and third-dimensional contact faces (40) (41) (43) with a point surface, such as Figures 4 to 6. Of course, if the detecting element (25) touches the lateral side of the workpiece (5〇), the 疋 actuation column (22) is thus offset from the one or two of the first or second measuring groove (34) (35). The dimension contact surface (40) (41) allows the sensor (26) to detect the reference plane coordinates in that direction. In this way, the creation of the three-point coplanar equilibrium state, regardless of the direction in which the reference plane is measured, means the measurement state of the seventh diagram, even if the third measuring slot (36) touches the column ( 22) There is detachment due to the measurement of the reference plane in the corresponding direction, but the remaining one of the touch columns (2 2) still contacts the first and second measuring slots (3 4) (3 5), respectively, and the detecting element (2 5) The detection head (2 5) is in contact with the workpiece ($ 〇), so the three-point immobile state provides a shared and balanced stability and balance. The measurement can be accurate and more accurate. Once the creation is detached, each of the touch columns (22) is returned. To the first, second, = trough (34) (35) (36), is the return to the immediate zero return state, to ensure that the residual edge will not be lost, resulting in a value overlap overlap error when re-measurement, this The creation of real can improve the measurement accuracy. The above embodiments are merely illustrative of the techniques of the present invention and their effects, and are not intended to limit the present invention. Anyone skilled in the art can modify and change the above embodiments without violating the technical principles and spirit of this creation. Therefore, the scope of protection of this creation should be as listed in the patent application scope mentioned later. . 9 M311515
