[0038] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0039] Reference Figures 1 to 12 As shown, an automatic multi-faceted grinding drill machine of this embodiment includes a worktable 1 and a positioning detection mechanism disposed on the worktable 1. The positioning detection mechanism includes a base 11, a first moving part and a photoelectric angle sensor. The base 11 and the worktable 1 are detachably connected by a plurality of studs and nuts.

[0040] A photoelectric angle sensor is fixedly connected to the workbench 1. A first support plate 13 is slidably connected to the base 11. Multiple first slide rails are fixedly connected to the base 11. A first slider is slidably connected to the slide rails. The first slider is fixedly connected to the first support plate 13 to increase the stability of the first support plate 13 during the sliding process. The first moving part is used to drive the first support plate 13 to move along its length direction.

[0041] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a drill bit clamping mechanism is provided on the first support plate 13. The drill bit clamping mechanism includes a housing 31 and a main shaft 32. The housing 31 is fixedly connected to the first support plate 13. A through hole 311 is provided in the housing 31. The main shaft 32 passes through the through hole 311 and is rotatably connected to the housing 31. A deep hole 321 is provided at one end of the main shaft 32, and a clamping hole 322 is provided at the other end of the main shaft 32. The clamping hole 322 communicates with the deep hole 321. A pull rod 33 is slidably connected in the deep hole 321. A chuck 34 is movably connected in the clamping hole 322. The chuck 34 is detachably connected to the pull rod 33. A first power unit is fixedly connected to the housing 31. The first power unit is connected to the pull rod 33 and is used to drive the pull rod 33 to move along its length.

[0042] A robotic arm and tooling are fixedly connected to the workbench 1. The tooling has multiple placement slots, in which drill bits are placed. The robotic arm picks up the drill bits and puts them into the chuck 34.

[0043] When the tail of the drill bit is placed into the chuck 34, the first power unit pulls the pull rod 33, causing the pull rod 33 to move toward the side of the first power unit. The movement of the pull rod 33 will drive the chuck 34 to move in the same direction. The chuck 34 retracts under the action of the clamping hole 322 on the spindle 32, thereby clamping the drill bit. This can quickly clamp the drill bit, improve the clamping efficiency and clamping force, and prevent the drill bit from loosening between the chuck 34 and the chuck.

[0044] Reference Figure 3 As shown, a second power unit is provided on the housing 31. The second power unit is used to drive the spindle 32 to rotate. The pull rod 33 is rotatably connected to the second power unit. A threaded groove 331 is opened at the end of the pull rod 33 near the chuck 34. The chuck 34 is threadedly connected to the pull rod 33 through the threaded groove 331. The second power unit can drive the drill bit to rotate, thereby adjusting the grinding angle of the drill bit. In cooperation with the first power unit, it can both clamp the drill bit and adjust the grinding angle of the drill bit.

[0045] Reference Figure 5 As shown, a grinding mechanism is also provided on the worktable 1. The grinding mechanism includes a base frame 41 and a first support 42 slidably connected to the base frame 41. The base frame 41 is detachably connected to the worktable 1. Multiple second slide rails are fixedly connected to the base frame 41, and multiple second sliders are fixedly connected to the bottom of the first support 42. The second sliders are slidably connected to the corresponding second slide rails. There are two second slide rails, and two second sliders are slidably connected to each second slide rail to increase the stability of the first support 42 during the sliding process.

[0046] A second movable part is provided on the base frame 41, which is used to drive the first support 42 to move along its length direction. A second support plate 43 is fixedly connected to the first support 42. A first driving part and a first grinding wheel 51 are provided on the second support plate 43. The first driving part is used to drive the first grinding wheel 51 to rotate. A second driving part and a second grinding wheel 61 are provided on the second support plate 43. The second driving part is used to drive the second grinding wheel 61 to rotate. A connecting frame is fixedly connected to the first support 42. A third driving part and a grooved wheel 71 are provided on the connecting frame. The third driving part is used to drive the grooved wheel 71.

[0047] The drill bit is moved by the first moving part, and the direction of movement of the drill bit is perpendicular to the direction of movement of the first support 42.

[0048] The second moving part works in conjunction with the movement of the drill bit to achieve the processing of the drill bit end by the first grinding wheel 51, the second grinding wheel 61 and the grooved wheel 71, thereby achieving automation, improving processing efficiency and better controlling the grinding range.

[0049] The rotation position and angle of the drill bit are detected by photoelectric angle sensors to determine the grinding angle of the drill bit, thereby judging whether the grinding angle and position of the drill bit are correct and preventing over-grinding or under-grinding.

[0050] Reference Figure 4 As shown, the first power unit includes a power cylinder 35, the output end of which is rotatably connected to the pull rod 33. A second bracket is fixedly connected to the housing 31, and the power cylinder 35 is fixedly connected to the second bracket. The power cylinder 35 is used to pull or push the pull rod 33, thereby clamping or releasing the drill bit.

[0051] Reference Figure 3 As shown, the second power unit includes a power motor 36, a first synchronous pulley 37, a second synchronous pulley 38, and a transmission belt 39. The output end of the power motor 36 is fixedly connected to the first synchronous pulley 37, the second synchronous pulley 38 is fixedly connected to the main shaft 32, and the transmission belt 39 is connected between the first synchronous pulley 37 and the second synchronous pulley 38. When the power motor 36 starts, it drives the first synchronous pulley 37 to rotate. The first synchronous pulley 37 drives the second synchronous pulley 38 through the transmission belt 39, thereby causing the main shaft 32 to rotate.

[0052] Before the spindle 32 rotates, the drill bit is already clamped by the chuck 34, so that the chuck 34 and the spindle 32 are tightly fitted. When the spindle 32 rotates, the spindle 32 will drive the chuck 34 and the pull rod 33 to rotate at the same time, so that the grinding angle of the drill bit can be adjusted to prevent the drill bit from being ground in the wrong position.

[0053] Multiple bearings are provided between the spindle 32 and the housing 31. There are two sets of bearings, with the two sets of bearings located at both ends of the spindle 32, to increase the stability of the spindle 32 rotation.

[0054] A step is formed on the spindle 32. The step abuts against one of the bearings and against the outer bearing in the second set of bearings, which serves to position the spindle 32 and determine its installation position.

[0055] In addition, a retaining ring is fitted on the main shaft 32, and a locking nut is threaded onto the main shaft 32. The first synchronous pulley 37 is located between the retaining ring and the locking nut.

[0056] The retaining ring abuts against the outer bearing in the first set of bearings, which positions the retaining ring and, through the cooperation of the locking nut, positions the first synchronous pulley 37.

[0057] A bushing is fitted on the main shaft 32.

[0058] Reference Figure 11 and Figure 12 As shown, a third support 14 is provided on the workbench 1. The third support 14 includes an adjusting cylinder 141 and a support plate 142. A first U-shaped frame 15 is fixedly connected to the workbench 1. One end of the adjusting cylinder 141 is hinged to the first U-shaped frame 15. The other end of the adjusting cylinder 141 is fixedly connected to a second U-shaped frame 16. The support plate 142 is hinged to the second U-shaped frame 16. A photoelectric angle sensor is detachably connected to the support plate 142. A fixing block 17 is fixedly connected to the workbench 1. The support plate 142 is rotatably connected to the fixing block 17.

[0059] By adjusting the fit between the cylinder 141 and the support plate 142, the cylinder 141 drives the support plate 142 to rotate, thereby adjusting the installation angle of the support plate 142 for the photoelectric angle sensor.

[0060] A shaft is fixedly connected to the support plate 142. A first through hole 311 is provided on the fixing block 17. The shaft is rotatably connected to the first through hole 311. Multiple mounting holes are provided on the first through hole 311. Internal threads are provided in the mounting holes. Studs are connected to the internal threads of the mounting holes so that the studs abut against the shaft, thereby restricting the rotation of the shaft and preventing the support plate 142 from rotating due to gravity.

[0061] Reference Figure 12As shown, a positioning element 18 is fixedly connected to the fixing block 17. The positioning element 18 has a through groove 181. The through groove 181 divides the positioning element 18 into two positioning sections. Arc-shaped grooves 182 are provided on both sides of the through groove 181. A sleeve 19 is provided between the two arc-shaped grooves 182. The sleeve 19 is hollow inside, and the drill bit can pass through the sleeve 19. The sleeve 19 increases the stability of the drill bit, so that the drill bit will not shake during grinding.

[0062] The first moving part includes a first moving motor 21 and a first lead screw 22. The output end of the first moving motor 21 is fixedly connected to the first lead screw 22. The first lead screw 22 is threadedly connected to the first support plate 13. The first moving motor 21 drives the first lead screw 22 to rotate, thereby achieving the desired effect.

[0063] The second moving part includes a second moving motor 44 and a second lead screw 45. The output end of the second moving motor 44 is fixedly connected to one end of the second lead screw 45. The second lead screw 45 is threadedly connected to the first bracket 42. The second moving motor 44 drives the second lead screw 45 to rotate, thereby moving the first bracket 42. When the first bracket 42 moves, it will drive the first grinding wheel 51, the second grinding wheel 61 and the grooved wheel 71 to move simultaneously.

[0064] The second support plate 43 has a first arc-shaped hole 431, and a positioning plate 432 is detachably connected to the first arc-shaped hole 431. An arm plate and a first L-shaped plate are integrally formed on the positioning plate 432. The first drive motor 52 is fixedly connected to the first L-shaped plate. The second support plate 43 is located between the first L-shaped plate and the arm plate. A countersunk hole is opened on the arm plate, and a connecting hole is opened on the first L-shaped plate. A thread is formed in the connecting hole. The stud passes through the countersunk hole and the first arc-shaped hole 431 and is threadedly connected to the connecting hole, thereby adjusting the installation angle of the positioning plate 432, so that the grinding angle of the first grinding wheel 51 can be adjusted.

[0065] Reference Figure 5 , Figure 6 As shown, the first drive unit includes a first drive motor 52, a first transmission belt 53, and two first synchronous pulleys 54. The first drive motor 52 is fixedly connected to the positioning plate 432. The output end of the first drive motor 52 is fixedly connected to one of the first synchronous pulleys 54. The other first synchronous pulley 54 is fixedly connected to the first grinding wheel 51 and rotatably connected to the positioning plate 432. The first transmission belt 53 drives the two first synchronous pulleys 54 to rotate. The first drive motor 52 drives the first synchronous pulley 54 on it to rotate, and drives the other first synchronous pulley 54 to rotate through the first transmission belt 53, thereby causing the first grinding wheel 51 to rotate.

[0066] After the drill bit is clamped by the chuck 34, the first moving part drives the first support plate 13 to move, so that the first grinding wheel 51 approaches the end of the drill bit, thereby grinding the drill bit and forming the front angle of the drill bit.

[0067] Reference Figure 7 and Figure 8 As shown, a second arc-shaped hole 433 is provided on the second support plate 43, and an adjusting plate 46 is rotatably connected to the second support plate 43. A rotating shaft is threadedly connected to the second support plate 43, and the rotating shaft is fixedly connected to the adjusting plate 46. A first threaded hole 461 is provided on the adjusting plate 46, and a first bolt 462 is threadedly connected between the first threaded hole 461 and the second arc-shaped hole 433. When the first bolt 462 is loosened, the adjusting plate 46 can be rotated, so that the adjusting plate 46 rotates circumferentially along the central axis of the rotating shaft to adjust the grinding angle of the second grinding wheel 61.

[0068] A slide 47 is slidably connected to the adjusting plate 46, and a second bolt 471 is rotatably connected to the slide 47. A second threaded hole 463 is provided on the adjusting plate 46, and the second bolt 471 is threadedly connected to the second threaded hole 463. A frame is fixedly connected to the slide 47, and a second drive unit and a second grinding wheel 61 are provided on the frame. Dovetail grooves are provided on both opposite sides of the adjusting plate 46, and a protrusion is formed on the slide 47. The protrusion and the dovetail groove cooperate to slide, increasing the stability of the slide 47 during the sliding process.

[0069] Rotating the second bolt 471 can adjust the length of the second bolt 471 extending out of the second threaded hole 463, thereby allowing the slide 47 to slide on the adjusting plate 46 and changing the grinding position of the second grinding wheel 61.

[0070] The second drive unit includes a second drive motor 62, a second transmission belt 63, and two second synchronous pulleys 64. The output end of the second drive motor 62 is fixedly connected to one of the second synchronous pulleys 64, and the other second synchronous pulley 64 is fixedly connected to the second grinding wheel 61 and rotatably connected to the frame. The second transmission belt 63 is connected between the two second synchronous pulleys 64. The second drive motor 62 drives the second synchronous pulley 64 on it to rotate, and drives the other second synchronous pulley 64 to rotate through the second transmission belt 63, thereby causing the second grinding wheel 61 to rotate.

[0071] The outer diameter of the second grinding wheel 61 is larger than that of the first grinding wheel 51. The first grinding wheel 51 first grinds the drill bit to form the front angle of the drill bit. Then, the first support 42 is reset under the drive of the second lead screw 45. After resetting a short distance, the drill bit is moved so that it is close to the second grinding wheel 61, thereby realizing the grinding of the end of the drill bit by the second grinding wheel 61 to form the back angle of the drill bit.

[0072] Reference Figure 9As shown, the third drive unit includes a third drive motor 72, a third transmission belt 73, and two third synchronous pulleys. The output end of the third drive motor 72 is fixedly connected to one of the third synchronous pulleys, and the other third synchronous pulley is fixedly connected to the grooved pulley 71. The third transmission belt 73 is connected between the two third synchronous pulleys. The third drive motor 72 drives the third synchronous pulley on it to rotate, thereby driving the other third synchronous pulley to rotate through the third transmission belt 73, causing the grooved pulley 71 to rotate.

[0073] After the drill bit has finished grinding the front and rear corners, the first support 42 continues to reset under the drive of the second lead screw 45, and the drill bit also returns to its original position. After the grooving wheel 71 is started, the drill bit moves toward the grooving wheel 71. The grooving wheel 71 opens the grooving angle at the end of the drill bit, thus completing the processing of the drill bit.

[0074] A movable frame is slidably connected to the connecting frame, and a support frame is fixedly connected to the movable frame. A third drive motor 72 is fixedly connected to the support frame. A storage unit is rotatably connected to the connecting frame. A third threaded hole is opened on the support frame. A handwheel is threadedly connected to the third threaded hole. The handwheel includes a rocker arm and a threaded shaft. A crank seat is fixedly connected to the connecting frame. The threaded shaft is rotatably connected to the crank seat, and the threaded shaft is threadedly connected to the third threaded hole. The worker can move the support frame by turning the handwheel.

[0075] Because the support frame and the movable frame are fixedly connected, the movable frame moves with the support frame, thereby driving the grooved wheel 71 to move, so that the grooved wheel 71 moves closer to or away from the drill bit. At this time, the moving direction of the grooved wheel 71 is perpendicular to the moving direction of the first support 42.

[0076] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
