In this specification, one direction may be, for example, the X-axis direction, and the two directions may be the Y-axis direction in a direction perpendicular to one direction. And the three directions may be Z-axis directions perpendicular to the plane formed by one direction and two directions. Thus, the directions 1, 2 and 3 mean directions perpendicular to each other. In addition, the plane angle means an angle in the circumferential direction of an arbitrary circle located on a plane formed by one direction and two directions. Specifically, the angle of rotation of the chuck module 16 with respect to the central axis of the chuck module 16 it means.

The 1, 2, and 3 directions can be set variously, and the plane on which the plane angle is set can be determined based on various directions.

The planar table 111 can be fixed to the frame 11 and the frame 11 can be shaped like a box so that the planar table 111 can be fixed. The planar table 111 may have a shape such that the upper surface thereof is entirely planar and the module moving in one direction or two directions is moved on the same plane. The planar table 111 may have any structure known in the art in which the top surface is planar.

The first and second mobile units 13 and 14 have a function of disposing the chuck module 16 at an arbitrary position on the plane and the three mobile units 17 have a function of moving the spindle module 18 up and down .

The one mobile unit 13 and the two mobile units 14 may be in the form of a linear rail or a linear slider moving in one and two directions, respectively. The chuck module 16 can be moved in one or two directions by the operation of the 1-position setting handle 133 and the 2-position setting handle 143 to the machining position. The operation of the 1-position setting handle 133 and the 2-position setting handle 143 can be performed, for example, by a driving device such as a motor or manually. The positioning handle may have any shape known in the art and a positioning handle may be disposed for actuating movement of the spindle module 18 or the chuck unit 161. [ Various position setting handles for linear movement of the various units can be applied to the tap drill machine according to the present invention, and the present invention is not limited to the embodiments shown.

1 moving unit 13 may be provided with a suitable supporter so that the machining table 15 can be fixed. An adjustment unit 162 such as a servo motor may be disposed above the processing table 15. And a chuck unit 161 for fixing a workpiece to be tapped on the upper side of each adjustment unit 162 can be arranged to be rotatable by each adjustment unit 162. [ In this structure, the machining table 15 is moved along the one moving unit 13 by the operation of the one positioning handle 133, and the two moving units 14 are moved by the operation of the two positioning handle 143 Can be moved along. The moving structure of the machining table 15 along the one moving unit 13 or the two moving units 14 as described above may have any structure applied to the machine tool field and the present invention is not limited to the illustrated embodiment . It is possible to have a structure in which the flat table 111 can move according to the design structure. Thus, the position in the plane formed by the first and second directions of the chuck module 16 or the XY plane can be achieved by various methods.

The angle adjustment unit 162 fixed to the machining table 15 may be a drive unit such as a servomotor capable of adjusting the angle of rotation and the axis of rotation of each adjustment unit 162 may be located at the center of the chuck module 16 And can be arranged to face three directions while being positioned. And the chuck unit 161 can be coupled to each control unit 162 so as to be rotatable by the rotation center axis.

The chuck unit 161 may have various structures capable of fixing the workpiece, and may be made of, for example, a movable jaw shape, a clamp structure, or a jig structure. The chuck module 16 is located at a machining position on a plane by one mobile unit 13 and two mobile units 14 and the positions of the tabs formed at different positions in the workpiece fixed to the chuck module 16 are Can be determined by each control unit 162. And the tap can be machined at various positions of the workpiece by the operation of the spindle module 18 to which the tapping tool is fixed.

The spindle module 18 can be disposed above the chuck module 16 to be movable up and down. The movement of the spindle module 18 can be guided by the three guide members 173 disposed in the three-way frame 12. [ Specifically, the three-way mobile unit 17 includes three tables 175 coupled to the spindle module 18; 3 guide member 173 for guiding movement of the table 175; And a cylinder unit 171a for moving the three tables 175 along three guide members 173 in three directions.

3 table 175 is attached to three guide members 173 which are fixed to the three-way frame 12 and extend in three directions or Z-axis directions while fixing the spindle module 18 with suitable fixing means or brackets, It can be arranged to be movable. 3 The cylinder unit 171a for moving the table 175 can be arranged in a structure extending along three directions and the cylinder unit 171a can be moved along three directions along the cylinder moving member 171 . The cylinder unit 171a can be moved along the cylinder moving member 171 and the moving distance of the cylinder unit 171a along the cylinder moving member 171 can be limited by the pressure. Specifically, when the pressure of the cylinder unit 171a moves downward, the pressure of the cylinder unit 171a may be restricted to prevent the cylinder unit 171a from moving along the cylinder-moving member 171 when the pressure is higher than a predetermined level. Such a restricting pressure can be set in advance, whereby the tab or the workpiece can be prevented from being damaged in the tapping process. The cylinder unit 171a can be moved by the action of hydraulic pressure or a motor, but is not limited thereto. Movement of the spindle module 18 by the three planar tables 175, the three guide members 173 of the linear slider structure, and the cylindrical cylinder unit 171a extending in three directions in this manner ensures the accuracy of positioning So that the movement is stabilized. It also ensures that taps or workpieces are not damaged during tapping. The vertical position of the spindle module 18 can be accurately and stably determined. And the spindle unit 181 is rotated at a predetermined fixed position in the tap forming process.

The spindle module 18 includes a spindle unit 181 to which the tapping tool is fixed; A spindle adjusting unit 182 for rotating the spindle unit 181; And a tool drive unit 19 such as a spindle unit 181 or a hydraulic motor for rotating the tapping tool.

The spindle unit 181 may have various structures for fixing the tapping tool such as a drill and may be arranged to be movable up and down by movement of the cylinder unit 171a and operation of the spindle adjusting unit 182 . The tapping tool fixed to the spindle unit 181 or the spindle unit 181 may be rotated by the tool driving unit 19 such as a servo motor or a hydraulic motor to tap the workpiece. The rotational torque of the spindle unit 181 can be limited to the tool driving unit 19 in the process of tapping. Specifically, the tool drive unit 19 may be a hydraulic motor operated by hydraulic pressure or a servo motor capable of restricting rotation torque, and the limit torque may be predefined. And operation of the tool drive unit 19 may be interrupted when a torque exceeding the limit torque is required in the tapping process. This prevents damage to the tab or damage to the workpiece. Such setting of the limit torque is particularly useful in the processing of the tab that does not penetrate the workpiece. In addition, the rotational speed of the tool drive unit 19 can be preset, and the rotational speed can be adjusted. As described above, it is possible to use a pressure motor or a similar drive unit capable of adjusting the torque or speed of the tool drive unit 19. [

The tapping positions at different positions of the workpiece can be determined by the respective adjustment unit 162 described above. The tool drive unit 19 can be fixed to the tool setting unit 183 disposed above the spindle adjusting unit 182 and the rotation of the tool processing tool can be adjusted by the tool setting unit 183. [ When one tap is to be machined at different positions along the circumference, the spindle unit 181 must be moved to the 2-tap position after one tap has been machined by the spindle unit 181 at the 1 position. In this case, the chuck unit 161 can be rotated at a predetermined angle by the angle adjusting unit 162. Accordingly, the workpiece is rotated and the spindle unit 181 can be positioned at the two-tap position. The taps can be processed at the two-tap position by the operation of the tool drive unit 19. [ In the processing of the taps, the limit torque can be set in advance, and the tool drive unit 19 can be operated within a predetermined limit torque range. The chuck unit 161 can be rotated by a predetermined angle, for example, 30 degrees, 45 degrees or 90 degrees, by each control unit 162. [ The predetermined angle may be determined by software connected to the tap drill machine 10. [ Then, one tap is machined by the spindle unit 181 at the position 1 of the workpiece, and the chuck unit 161 is rotated by each adjusting unit 162, so that the two-tap machining position is located in the spindle unit 181. In this process, when movement along the XY plane is required, the chuck module 16 can be moved along one mobile unit 13 or two mobile units 14.

As such, the tap drill machine 10 according to the present invention allows the chuck unit 161 to be rotated by an angle adjustment unit 162 such as a servomotor automatically or at an angle determined by operating software, So that the machining position can be precisely adjusted while being easily adjusted. In addition, the rotation of the spindle unit 181 is controlled by the tool drive unit 19 capable of setting a torque such as a hydraulic motor so that tapping can be stably performed.

The movement of the tab forming position can be done in various ways, and the present invention is not limited to the embodiments shown.

The pair of first guide members 151 can be moved in one direction along one mobile unit 13 by the operation of the first positioning handle 133. [ A spherical moving tab may be formed at an upper end portion of the pair of first guide members 151 and a tab receiving groove 152 may be formed at a lower portion of the processing table 15. The pair of first guide members 151 can be separated from each other and extend along two directions. And by the operation of the two-position setting handle 143, the machining table 15 can be guided by the tab receiving groove 152 and moved along the two-movement unit 14. [

The chuck unit 161 may be composed of two to four large jaws arranged along the circumference at intervals of, for example, 120 degrees apart from each other so as to face each other, and the plurality of jaws are moved in the horizontal direction, Can be adjusted. The plurality of jaws can be moved along the linear slider by operation of the positioning handle described above. A plurality of groups of moving structures may be of any type known in the art, and the present invention is not limited to the embodiments shown. The fixing shaft 263 may be disposed at the center of the plurality of jaws and the fixing protrusion 261 for fixing the workpiece to the end of the fixing shaft 263 may be formed. The fixed shaft 263 may have a central axis function for rotation of each adjustment unit 162. [ A fixing bracket 265 for fixing the fixing shaft 263 to the adjusting unit 162 is disposed below the fixing shaft 263 and the fixing bracket 265 is fixed to the respective adjusting unit 264 by an appropriate fastening unit 264. [ May be rotatably coupled to the shaft (162).

The chuck module 16 can be made of various structures for fixing the workpiece, and the present invention is not limited to the embodiments shown.

Figure 3 shows an embodiment of a spindle module of a tap drill machine according to the invention.

3, the spindle module may be fixed to the table 175, and the spindle unit 181 may be moved up and down in accordance with the movement of the cylinder unit 171a. When the three-directional position of the spindle unit 181 is determined, the tapping tool fixed to the spindle unit 181 or the spindle unit 181 is rotated by the tool processing unit 19 so that the tab can be machined on the workpiece. The spindle unit 181 can be moved up and down along the three guide members 173 while the moving pressure is controlled by the cylinder unit 171a. Up and down movement of the spindle unit 181 may be limited by the pressure of the cylinder unit 171a and the machining torque of the spindle unit 181 may be limited by a preset torque of the tool drive unit 19 such as a hydraulic motor . Thereby allowing the tabs to be stably formed at a predetermined depth. The pressure of the cylinder unit 171a or the torque of the tool drive unit 19 can be set and controlled by a control unit installed in the tap drill machine.

The spindle module can be operated in various ways and the present invention is not limited to the embodiments shown.

FIG. 4 shows an embodiment of a process for machining a plurality of tabs in a tap drill machine according to the present invention.

Referring to FIG. 4, a workpiece or workpiece may be fixed to the chuck unit of the tap drill machine to continuously process a plurality of tabs on the workpiece (P41). And the chuck unit may be moved along the XY-plane and positioned below the spindle unit (P42). Then, the reference position of each adjustment motor such as the servo motor can be set and stored in the control unit (P43). The control unit may include operating software and may have information on the rotation angle of the chuck unit depending on the position of the plurality of taps to be machined. The spindle unit can be moved in the Z-axis direction for the machining of one tap (P44), and the one tap of the chuck unit is aligned based on the reference position of the predetermined chuck unit (P45). And the torque of the tapping tool can be determined. The torque setting of such a processing tool means that the operation of the tapping tool is stopped when the torque becomes a certain level or more, for example. The torque of the tapping tool can be determined by setting the operating torque to the hydraulic motor operated by the hydraulic pressure or the tool processing unit described above. The pressure for restricting the Z axis movement of the spindle can also be set. For example, the pressure can be increased while the spindle unit is moving downward, and the movement can be restricted if the pressure is above a certain level. When the torque of the tool machining unit and the limiting pressure for the Z axis movement are determined in this way, one tapping tool fixed to the spindle unit can be operated to process one tap (P46). When one tap is machined, it is moved in the Z direction of the spindle unit, and the chuck unit can be rotated at a predetermined angle (P47). Then, the spindle unit is moved in the Z direction so that two taps can be machined. In this way, the plurality of tabs can be continuously machined by the rotation of the chuck unit and the movement of the spindle unit. The plurality of tabs disposed along the circumference of the plane can be continuously and automatically machined by adjusting the rotation angle of the chuck unit by the operation of the servomotor in the above manner. Also, the tab having a predetermined depth can be stably machined by the restricting pressure restricting the Z axis movement of the spindle unit.

The tap drill machine according to the present invention can be operated in various ways, and the present invention is not limited to the embodiments shown.

The tap drill machine according to the present invention allows the tap to precisely control the machining position. The tap drill machine according to the present invention automatically adjusts the position where the tabs are formed in the circumferential direction along the plane in the molding fixed to the chuck. In addition, the tap drill machine according to the present invention allows the chuck on which the formed product is fixed to be adjusted in position along the plane table, so that tapping of various sizes can be performed while making tapping simple.
