Description

Technical Field

[0001] This invention relates to a multi-station drill bit dynamic positioning and high-precision grinding mechanism, and belongs to the field of multi-station drill bit dynamic positioning and high-precision grinding mechanism. Background Technology

[0002] The machining process for drill bits includes helical groove cutting, end face grinding, edge trimming, and efficient loading and unloading operations, ultimately transforming them into precision drill bits. In the grinding process, existing equipment grinds individual drill bits, without the capability for large-scale simultaneous grinding, resulting in low production output. Therefore, how to simultaneously grind drill bits in large batches is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0003] To overcome the above-mentioned shortcomings, the purpose of this invention is to provide a multi-station drill bit dynamic positioning and high-precision grinding mechanism.

[0004] To achieve the above objectives, the technical solution adopted in this invention is: a multi-station drill bit dynamic positioning and high-precision grinding mechanism, comprising a grinding disc, a drill bit, a chuck, and a housing. The drill bit is inclined relative to the grinding disc, with its front end abutting against the grinding disc and its end connected to the chuck. The housing contains an adjustment section and several rotating sections. Each rotating section includes a first hinge seat, a second hinge seat, a mounting plate, a motor, a bearing seat, and a rotating shaft. The motor is fixedly connected to the mounting plate, and its output shaft is fixedly connected to the chuck via the rotating shaft. Both ends of the rotating shaft are rotatably connected to the mounting plate via a bearing seat. One end of the mounting plate is rotatably connected to the inner wall of the housing via the first hinge seat. The other end of the mounting plate is connected to the second hinge seat; the front end face of the housing is provided with several slits, through which the rotating shaft passes; the adjustment part includes a connecting rod, a crossbar, a lead screw, a rotating seat, an adjustment plate, and a guide rod. A rotating seat is provided at the center of both the front and rear sides of the housing. The lead screw is rotatably connected in the rotating seat, and the end of the lead screw is vertically connected to the center of the crossbar. The two ends of several guide rods are fixedly connected to the front and rear sides of the housing, respectively. A threaded hole is provided at the center of the adjustment plate, and several through holes are provided at the edge. The threaded hole is screwed to the lead screw, and the guide rod slides in the through holes; a third hinge seat is fixedly connected to the side of the adjustment plate, and the two ends of the connecting rod are rotatably connected to the third hinge seat and the second hinge seat, respectively.

[0005] A further feature of the present invention is that the adjusting part is located at the central axis of the housing, and several rotating parts are rotatably connected to the adjusting part.

[0006] A further feature of the present invention is that the housing is provided with a plurality of adjustment parts, and the adjustment parts are paired with the rotation parts one by one.

[0007] A further feature of the present invention is that the width of the slit is equal to the diameter of the rotating shaft.

[0008] A further feature of the present invention is that the plurality of rotating parts are arranged in a ring array with the central axis of the housing as the axis of rotation.

[0009] A further feature of the present invention is that the rear end face of the housing is a rear cover, and the rear cover is connected to the housing by bolts.

[0010] Compared with the prior art, the beneficial effects of this invention are as follows: Rotating the horizontal bar by hand drives the lead screw to rotate. The lead screw is screwed into the threaded hole, causing the adjusting plate to move axially along the lead screw. Since the edge of the adjusting plate is fixedly connected to the third hinge seat, and the connecting rod is hinged between the end of the mounting plate and the third hinge seat, and the other end of the mounting plate is rotatably connected to the first hinge seat, which is fixedly connected to the inner wall of the housing, the mounting plate can be rotated around the first hinge seat, changing the angle of the mounting plate. Because the mounting plate is equipped with a motor, bearing seat, and shaft, and the shaft is connected to the drill bit via a chuck, the angle of the drill bit changes with the angle relative to the mounting plate. This achieves the purpose of changing the angle between the drill bit and the grinding disc. The motor drives the drill bit to rotate, while the grinding disc rotates around its own axis. After grinding, a conical structure can be formed on the end face of the drill bit. Attached Figure Description

[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0017] Example 1: See Appendix Figure 1-3As shown, the multi-station drill bit dynamic positioning and high-precision grinding mechanism in this embodiment includes a grinding disc 1, a drill bit 2, a chuck 3, and a housing 5. The drill bit 2 is inclined relative to the grinding disc 1, with its front end abutting against the grinding disc 1 and its end connected to the chuck 3. The housing 5 is internally provided with an adjustment part 21 and several rotating parts 22. Each rotating part 22 includes a first hinge seat 6, a second hinge seat 20, a mounting plate 7, a motor 8, a bearing seat 9, and a rotating shaft 10. The motor 8 is fixedly connected to the mounting plate 7, and the output shaft of the motor 8 is fixedly connected to the chuck 3 via the rotating shaft 10. Both ends of the rotating shaft 10 are rotatably connected to the mounting plate 7 via a bearing seat 9. One end of the mounting plate 7 is rotatably connected to the inner wall of the housing 5 via the first hinge seat 6, and the other end of the mounting plate 7 is connected to the second hinge seat 20. The front end face of the housing 5 is provided with several slits 4, and the rotating shaft 10 passes through the slits 4. The adjusting part 21 includes a connecting rod 13, a crossbar 19, a lead screw 16, a rotating seat 17, an adjusting plate 15, and a guide rod 18. The center of the front side and the rear side of the housing 5 are provided with rotating seats 17, and the lead screw 16 is rotatably connected in the rotating seat 17. The end of the lead screw 16 is vertically connected to the center of the crossbar 19. The two ends of several guide rods 18 are fixedly connected to the front side and the rear side of the housing 5, respectively. The center of the adjusting plate 15 is provided with a threaded hole 12, and the edge is provided with several through holes 11. The threaded hole 12 is screwed to the lead screw 16, and the guide rods 18 slide in the through holes 11. The side of the adjusting plate 15 is fixedly connected with a third hinge seat 14, and the two ends of the connecting rod 13 are rotatably connected to the third hinge seat 14 and the second hinge seat 20, respectively.

[0018] The adjusting part 21 is located at the central axis of the housing 5, and several rotating parts 22 are rotatably connected to the adjusting part 21. The width of the slit 4 is equal to the diameter of the rotating shaft 10. The several rotating parts 22 are arranged in a circular array around the central axis of the housing 5. During the adjustment process, the lead screw 16 and the mounting plate 7 are always in the same plane. In this embodiment, there is only one adjusting part 21, located at the central axis of the housing 5. The angles of all rotating parts 22 are adjusted simultaneously. The rear end face of the housing 5 is a rear cover 23, which is connected to the housing 5 by bolts 24.

[0019] Example 2: See Appendix Figure 1-4 As shown, this embodiment illustrates the multi-station drill bit dynamic positioning and high-precision grinding mechanism. Embodiment two is essentially the same as embodiment one, except that the housing 5 is provided with several adjustment sections 21, each paired with a rotating section 22. Each adjustment section 21 can adjust the angle of the rotating section 22.

[0020] In summary, the method of using the multi-station drill bit dynamic positioning and high-precision grinding mechanism of the present invention is as follows: Rotate the horizontal bar 19 by hand, driving the lead screw 16 to rotate. The lead screw 16 is screwed into the threaded hole 12, causing the adjusting plate 15 to move axially along the lead screw 16. Since the edge of the adjusting plate 15 is fixedly connected to the third hinge seat 14, and the connecting rod 13 is hinged between the end of the mounting plate 7 and the third hinge seat 14, and the other end of the mounting plate 7 is rotatably connected to the first hinge seat 6, which is fixedly connected to the inner wall of the housing 5, the mounting plate 7 can be rotated around the first hinge seat 6, changing the angle of the mounting plate 7. Since the mounting plate 7 is equipped with a motor 8, bearing seat 9, and rotating shaft 10, and the rotating shaft 10 is connected to the drill bit 2 via a chuck 3, the angle of the drill bit 2 changes with the angle relative to the mounting plate 7, thus achieving the purpose of changing the angle between the drill bit 2 and the grinding disc 1. The motor 8 drives the drill bit 2 to rotate, while the grinding disc 1 rotates around its own axis. After grinding, a conical structure can be formed on the end face of the drill bit 2. By installing several rotating parts 22 on the housing 5, and installing the drill bit 2 in the rotating parts 22, the purpose of mass grinding can be achieved simultaneously, thus increasing production output.

Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
