Description
Technical Field
The invention relates to a manufacturing tool and a manufacturing method of a drilling tool chuck.
Background
In tools for drilling, the drill bits are of various sizes in order to drill different hole diameters, and may be made of different materials in order to be suitable for drilling on different materials. Therefore, in order to mount the various drill bits described above, the drilling tool has a holding portion for holding the drill bit. Generally, the clamping portion has a drill chuck and three clamping jaws. The drill chuck is formed with a central through hole and three oblique holes, and the clamping jaws are respectively inserted into the oblique holes of the drill chuck. The user can control the clamping jaws to move towards the center of the drill chuck by rotating the drill chuck, so that the clamping jaws can tightly clamp the drill bit when the drill bit is positioned in the center through hole of the drill chuck.
however, the position of the clamping jaws is limited by the position of the inclined hole of the drill chuck, and if the inclined hole of the drill chuck is slightly inclined, the clamping jaws can hardly fix the drill bit along the center of the drill chuck. In the prior art, in order to produce a drill chuck with inclined holes at high precision positions, a drill chuck with inclined holes is mainly manufactured by common machining, and then the drill chuck with higher precision is selected from the drill chuck and machined, so as to ensure that the hole position of each inclined hole meets the required precision. In other words, the process of multiple machining takes a long time, and thus the number of machines that can be manufactured per unit time is limited. There is also a molding device in the prior art, which has an optical ruler to assist in positioning the drill chuck, but the optical ruler is expensive, so the molding device has a high cost and is not economical.
In view of the above, a better solution is proposed, and a problem to be solved is needed in the art.

Detailed Description
The technical means adopted by the invention to achieve the predetermined object of the invention are further described below with reference to the drawings and the preferred embodiments of the invention.
please refer to fig. 1 to fig. 3. The invention provides a three-hole drill chuck forming device which can be used for installing a cutter 31 and a workpiece A and enabling the cutter 31 to process the workpiece A. The three-hole drill chuck forming device has a workpiece table 10, a workpiece clamping assembly 20, and a tool driving assembly 30.
The workpiece clamping assembly 20 is disposed on the workpiece table 10, and has a first power unit 21, a transmission mechanism 22, a tooth clutch 23, an index plate 24, and a clamping mechanism 25, and optionally has an oil hydraulic mechanism (not shown). The transmission mechanism 22 has a first end and a second end opposite to each other, and the first end of the transmission mechanism 22 is connected to the first power unit 21. The tooth clutch 23 has a first end and a second end opposite to each other, and the first end of the tooth clutch 23 is connected to the second end of the transmission mechanism 22. The indexing disc 24 has a first side and a second side opposite to each other, and the first side of the indexing disc 24 is connected to the second end of the tooth clutch 23. The clamping mechanism 25 has a first side and a second side opposite to each other, the first side of the clamping mechanism 25 is connected to the second side of the index plate 24, and the second side of the clamping mechanism 25 can clamp the workpiece a.
in other words, the first power unit 21, the transmission mechanism 22, the tooth clutch 23, the index plate 24, and the clamping mechanism 25 are sequentially connected in series, so that the power of the first power unit 21 can be sequentially transmitted to the clamping mechanism 25 through the transmission mechanism 22, the tooth clutch 23, and the index plate 24, thereby rotating the clamping mechanism 25 and the workpiece a clamped by the clamping mechanism. The present invention utilizes the characteristic of zero backlash between the first end and the second end of the tooth clutch 23, and the first power unit 21 can immediately reflect the rotation angle of the first power unit 21 when transmitting by the tooth clutch 23, and the phenomenon of tolerance caused by the fact that the first power unit 21 must rotate an angle in advance to enable the structure to be tightly pressed to drive other components is avoided.
in this embodiment, the first power unit 21 includes a servo motor, the transmission mechanism 22 includes a reduction gear set, the clamping mechanism 25 has a plurality of clamping jaws 250 and a receiving space for receiving the workpiece a, and the oil pressure mechanism is connected to the clamping jaws 250 of the clamping mechanism 25. The clamping jaws 250 are evenly disposed around the accommodating space, and each clamping jaw 250 can be driven by the oil pressure mechanism to move along a direction perpendicular to the central axis of the accommodating space. Thus, the workpiece a can be gripped when the jaws 250 are both moved toward the central axis, while the workpiece a can be released when the jaws 250 are moved away from the central axis.
the tool driving assembly 30 is disposed on the workpiece stage 10 and can mount the tool 31 to drive the tool 31 to move back and forth along a motion path through the workpiece. Specifically, the tool driving assembly 30 further has a stage 32, a displacement base 33, a mounting mechanism 34, a second power unit 35, and optionally a third power unit 36. The stage 32 is provided on the workpiece table 10. The displacement base 33 is provided on the stage 32 and can move back and forth on the stage 32 in parallel to the movement path. The mounting mechanism 34 is provided on the displacement base 33, and therefore can move back and forth along the movement path parallel to the displacement base 33. The tool 31 is mounted to the mounting mechanism 34 so that the tool 31 can move back and forth along the path of motion to machine the workpiece a. The mounting mechanism 34 can adjust the position and angle of the tool 31 with respect to the workpiece a because the spindle on which the tool 31 is mounted can be adjusted vertically or horizontally and also can be adjusted in angle. The second power unit 35 is disposed on the displacement base 33 and can drive the mounting mechanism 34 and the tool 31 thereon to rotate, so as to process, for example, cut the workpiece a. The third power unit 36 is disposed on the stage 32 and can automatically drive the displacement base 33 to move back and forth.
please refer to fig. 4 to fig. 9. The invention also provides a forming method of the three-hole drill chuck, which can be executed by the forming device of the three-hole drill chuck. The first embodiment of the molding method of the present invention sequentially comprises the following steps:
(A) Installing a workpiece A: the workpiece a is mounted to the clamping mechanism 25 of the workpiece clamping assembly 20;
(B) Forming a first inclined hole a 1: the tool driving assembly 30 forms a first inclined hole a1 in the workpiece a;
(C) The first rotation: the first power unit 21 drives the index plate 24 to rotate 120 degrees through the tooth clutch 23;
(D) forming a second inclined hole a 1: the tool driving assembly 30 forms a second inclined hole a1 in the workpiece a;
(E) and (3) second rotation: the first power unit 21 drives the index plate 24 to rotate by 120 degrees through the tooth clutch 23; and
(F) Forming a third inclined hole a 1: the tool drive assembly 30 forms a third angled hole a1 in the workpiece a.
In other words, after the workpiece a is fixed, the tool 31 is used to drill a first inclined hole a1 in the workpiece a, then the workpiece a is rotated 120 degrees around its central axis to drill a second inclined hole a1, and finally the workpiece a is rotated 120 degrees around its central axis to drill a third inclined hole a 1.
Therefore, the forming method in the embodiment also utilizes the zero backlash characteristic of the tooth clutch 23, and can accurately control the rotary index plate 24 and the workpiece a thereon. However, in other embodiments, the present invention is not limited to the forming device, as long as the device for performing the forming process has the workpiece holding assembly 20, and the forming device can be implemented by different types of tool driving assemblies 30.
Please refer to fig. 4, fig. 5, fig. 7, and fig. 10. As mentioned above, the workpiece a is clamped by the movement of the clamping jaws 250 of the clamping assembly, but because the movement of the clamping jaws 250 is inevitable to have some errors, the central axis of the clamped workpiece a may not coincide with the central axis of the accommodating space, and therefore, the workpiece a may be displaced simultaneously after the workpiece a is rotated by the clamping mechanism 25. If the workpiece a is displaced, the distance between the second inclined hole a1 and the central axis of the workpiece will be different from the distance between the first inclined hole a1 and the central axis of the workpiece, which affects the precision of the manufactured drill chuck. Therefore, the second embodiment of the molding method sequentially comprises the following steps:
(A) Installing a workpiece A: the workpiece a is mounted to the clamping mechanism 25 of the workpiece clamping assembly 20;
(B) forming a first inclined hole a 1: the tool driving assembly 30 forms a first inclined hole a1 in the workpiece a;
(C) Measuring: measuring the position and angle of the first inclined hole A1;
(D) the first rotation: the first power unit 21 drives the index plate 24 to rotate 120 degrees through the tooth clutch 23;
(E) adjusting for the first time: adjusting the position and angle of the workpiece A on the clamping mechanism 25 according to the measurement result;
(F) Forming a second inclined hole a 1: the tool driving assembly 30 forms a second inclined hole a1 in the workpiece a;
(G) and (3) second rotation: the first power unit 21 drives the index plate 24 to rotate by 120 degrees through the tooth clutch 23;
(H) And (3) second adjustment: adjusting the position and angle of the workpiece A on the clamping mechanism 25 according to the measurement result; and
(I) Forming a third inclined hole a 1: the tool drive assembly 30 forms a third angled hole a1 in the workpiece a.
The difference between the second embodiment and the first embodiment of the forming method is that after the first inclined hole a1 is formed, the workpiece a is rotated after the position and angle of the first inclined hole a1 are measured by a positioning device (not shown), and then after the workpiece is rotated and before the second inclined hole a1 and the third inclined hole a1 are formed, the position and angle of the workpiece a are adjusted according to the measurement results of the positioning device, so that the distance between the formed second inclined hole a1 and the formed third inclined hole a1 relative to the center of the workpiece a is equal to the distance between the formed first inclined hole a1 relative to the center of the workpiece a. Of course, if the workpiece a is still in the proper position after rotation, the adjustment step can be omitted. Therefore, the forming method can have higher accuracy by assisting the positioning of the workpiece A through the positioning device.
In this embodiment, the positioning device can be a jig, so as to measure and adjust the position and angle of the workpiece a. In other embodiments, the positioning apparatus may include a measuring unit and a workpiece a adjusting unit, which can achieve the same function.
in other embodiments, the positioning device may be used to measure the position and angle of the workpiece a after the workpiece a is fixed to the fixture 25 and before the workpiece a is rotated for the first time, for example, the workpiece a is fixed to the fixture 25 and measured before the first inclined hole a1 is formed. And after the workpiece A is rotated, the position and the angle of the workpiece A are adjusted according to the measurement result of the positioning device before the second inclined hole A1 and the third inclined hole A1 are formed.
In summary, in the forming apparatus and the forming method of the three-hole drill chuck according to the present invention, due to the zero backlash of the tooth clutch 23, when the first power unit 21 is driven by the tooth clutch 23, the rotation angle of the first power unit 21 can be immediately reflected, so that the rotation angle of the workpiece a can be accurately controlled, and the position and angle accuracy of the inclined hole a1 formed on the workpiece a can be improved.
the present invention is capable of other embodiments, and various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention as defined in the appended claims.
