[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] In the description of the present invention, it should be understood that the terms "open hole", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0020] Please refer to Figures 1-7As shown in the figure, the present invention is a conical sleeve type shaft disc drilling device, which includes a workbench 1, and a protective cover 2 is installed outside the workbench 1. A lifting feed box 3 is installed above the workbench 1, and a drill bit 31 is installed at the bottom of the feed box 3; A clamping fixture 4 is installed on the workbench 1. The clamping fixture 4 includes a bottom tray 41 and an upper tray 42. The bottom tray 41 is connected to the moving guide rail of the workbench 1, and the upper surface of the bottom tray 41 is connected to the upper tray 42 by a plurality of countersunk screws. A plurality of radial grooves 421 are arranged in an array on the wall surfaces where the bottom tray 41 and the upper tray 42 are in contact; A lead screw member 43 is rotatably installed in each radial groove 421 through a bearing, and a driven bevel gear 44 is fixedly installed at the end of the lead screw member 43 facing the central hole 423 of the bottom tray 41; A driving bevel gear 45 meshing with a plurality of driven bevel gears 44 is installed at the bottom of the central hole 423 of the bottom tray 41; An adjustable clamping block assembly 5 is installed on each lead screw member 43. The adjustable clamping block assembly 5 is used for clamping and positioning the shaft disc part 9 to be drilled. Specifically, the present invention sets a clamping fixture 4 on the workbench 1. The bottom tray 41 and the upper tray 42 are connected by a plurality of countersunk screws, so that a plurality of circumferentially arrayed lead screw members 43 can be rotatably installed in the radial grooves 421 opened on the wall surfaces where the upper tray 42 and the bottom tray 41 are in contact through a plurality of bearings. Therefore, when the servo motor fixed in the middle of the bottom tray 41 works, it can drive a plurality of circumferentially arrayed meshing driven bevel gears 44 to rotate through the driving bevel gear 45. Furthermore, the lead screw members 43 will drive the circumferentially arrayed adjustable clamping block assemblies 5 to approach or move away from each other. Then, the adjusted adjustable clamping block assemblies 5 perform accurate centering clamping on the shaft disc part 9. The moving guide rail on the workbench 1 can drive the clamping fixture 4 to move in the horizontal direction, so that the point to be drilled of the clamped shaft disc part 9 is aligned with the drill hole, realizing accurate drilling, punching or reaming processing. The adjustable clamping block assembly 5 can also be adjusted vertically in height and cooperate with the rotation of two symmetric lead screw members 43, so that two symmetric adjustable clamping block assemblies 5 after height adjustment clamp the erected conical sleeve part 91, which is convenient for radial drilling of the conical sleeve part 91 cooperating with the shaft disc part 9. Furthermore, it can improve the drilling, reaming or punching accuracy of the drilling device of the present invention for the conical sleeve type shaft disc part 9, and also improve the universality of the use of the drilling device.

[0021] In this embodiment, a sliding cavity 431 is formed at the end of the lead screw member 43 close to the driven bevel gear 44. A moving guide rod 46 is slidably inserted into the sliding cavity 431, and the outer end of the moving guide rod 46 is connected to the driven bevel gear 44. A guide cylinder 47 is fixedly provided at the bottom of the sliding cavity 431. A pushing rod 48 is slidably connected to the guide cylinder 47 through a sealing plug 6, and the outer end of the pushing rod 48 is connected to the moving guide rod 46. A gas guide pipe is communicated with the bottom of the guide cylinder 47, and a spring member is connected between the sealing plug 6 and the bottom of the guide cylinder 47. A plurality of long key grooves 461 are formed in a circumferential array on the moving guide rod, and the long key grooves 461 cooperate with a plurality of key blocks 432 fixedly provided at the opening of the sliding cavity 431. A plurality of positioning columns 49 are fixedly provided at the notch of the radial groove 421 close to the central hole 423, and each positioning column 49 corresponds to a positioning socket 441 formed on the back of the driven bevel gear 44. Specifically, when the plurality of circumferentially arrayed adjustable clamping block assemblies 5 clamp the shaft disc member 9 to be drilled, at this time, the gas in the corresponding guide cylinder 47 is extracted by the gas guide pipe. The cooperation of the spring member, the pushing rod 48 and the moving guide rod 46 will pull the driven bevel gear 44 out of engagement with the driving bevel gear 45. At this time, the sliding driven bevel gear 44 will make the positioning socket 441 on the back sleeved on the positioning column 49, so as to facilitate the limited rotation of the plurality of lead screw members 43, so that the plurality of adjustable clamping block assemblies 5 can be fixed precisely to clamp the shaft disc member 9, preventing the adjustable clamping block assemblies 5 from loosening when the upper and lower two trays rotate, and affecting the accurate and safe drilling process of the shaft disc member 9. At the same time, the driving bevel gear 45 only plays a role of meshing and driving the plurality of driven bevel gears 44, and does not play a role of meshing and static for the plurality of driven bevel gears 44, so as to improve the service life of the mutually meshing bevel gears. When it is necessary to adjust the plurality of circumferentially arrayed adjustable clamping block assemblies 5, the gas filled in the guide cylinder 47 will push the driven bevel gear 44 to slide and engage with the driving bevel gear 45 through the sealing plug 6, the pushing rod 48 and the moving guide rod 46. Then, the driving bevel gear 45 will drive the plurality of driven bevel gears 44 to rotate. The cooperation of the key block 432 and the long key groove 461 can make the lead screw member 43 rotate, so as to facilitate the driving and sliding of the plurality of groups of adjustable clamping block assemblies 5. The sliding cooperation of the key block 432 and the long key groove 461 will not interfere with the normal sliding of the moving guide rod 46. When the left and right symmetric driven bevel gears 44 are disengaged from the driving bevel gear 45, and the front and back symmetric driven bevel gears 44 continue to be engaged with the driving bevel gear 45, then the rotation of the driving bevel gear 45 will only drive the front and back two groups of adjustable clamping block assemblies 5 to move away from or close to each other, so that the front and back two groups of adjusted adjustable clamping block assemblies 5 can clamp and fix the end face of the erected cone kit 91, so as to facilitate the radial drilling process on the cone kit 91, thereby improving the use range of the clamping fixture 4 of the present invention.

[0022] In this embodiment, the adjustable clamping block assembly 5 includes a connecting guide sleeve 51. Each lead screw member 43 is sleeved with a connecting guide sleeve 51 through a ball nut pair, and a guiding slider 52 is connected to the upper part of the connecting guide sleeve 51. The top of the guiding slider 52 extends out of a guiding square groove 422 radially opened on the upper tray 42 and is connected with a clamping block 53. The inner side surface of each clamping block 53 is arranged as an arc surface. The inner bottom of the guiding slider 52 is provided with a bottom cushion block 54, and the upper and lower surfaces of the bottom cushion block 54 are both flat. Specifically, the rotation of the lead screw member 43 will drive the guiding slider 52 to slide in the guiding square groove 422 through the cooperation of the ball nut pair and the connecting guide sleeve 51. The cooperation between the guiding slider 52 and the guiding square groove 422 will not cause it to rotate. Furthermore, the clamping block 53 will drive the bottom cushion block 54 to slide easily on the upper tray 42, so as to clamp the outer circumferential surface of the shaft disc part 9 with different diameters. The inner side surface of the clamping block 53 is arranged as an arc surface, which can make it accurately fit and clamp the shaft disc part 9 to be drilled. The bottom cushion block 54 can suspend and support the clamped shaft disc part 9, preventing the tip of the drill bit 31 from contacting the surface of the upper tray 42 after the shaft disc part 9 is drilled by the drill bit 31, thereby causing damage to it. The surface of the bottom cushion block 54 is flat, enabling it to accurately and flatly support the shaft disc part 9 to be drilled and preventing the shaft disc part 9 from tilting during clamping.

[0023] In this embodiment, a T-shaped guide groove 531 is opened downward on the upper surface of the clamping block 53. A moving slider 55 is arranged at the end surface of the bottom cushion block 54 close to the clamping block 53, and the other end of the moving slider 55 extends into the front and rear horizontal grooves of the T-shaped guide groove 531. An installation sleeve 56 is fixedly arranged at the extending end of the moving slider 55, and a support rod 57 is fixedly installed in the installation sleeve 56. Shaft rods 58 are fixedly arranged at both ends of the support rod 57. Vertical guide grooves 532 are opened on the front and rear groove walls of the front and rear horizontal grooves of the T-shaped guide groove 531. The end of the support rod 57 is slidably connected to the vertical guide groove 532 through a bearing. Specifically, the vertical guide groove 532 is a blind groove design. Therefore, when the bottom pad 54 slides upward to the top of the clamping block 53, the movable slider 55 will synchronously drive the installation sleeve 56, the support rod 57 and the shaft rod 58 matched with the bearing to slide to the top of the vertical guide groove 532, and then rotate the bottom pad 54 to make it vertical. Since the T-shaped guide groove 531 penetrates upward from the top of the clamping block 53, the movable slider 55 in the horizontal state will also synchronously rotate to the vertical state, and then press the bottom pad 54 in the vertical state downward to make its lower surface fit against the upper surface of the clamping block 53, and at this time, the inner side surface of the bottom pad 54 in the vertical state will extend out of the inner side of the clamping block 53, so that the bottom pads 54 that are close to each other and in the vertical state can accurately fit against the two end surfaces of the cone sleeve 91 in the vertical state, so as to clamp it. The bottom pad 54 is tightly processed, and due to the solid shape of the back side of the T-shaped guide groove 531, when the bottom pad 54 in the vertical state clamps the end of the cone sleeve 91, the bottom pad 54 will not rotate, thereby improving the stability and safety of the bottom pad 54 in the vertical state clamping the upright cone sleeve 91; when the bottom pad 54 needs to be rotated to be perpendicular to the clamping block 53, the bottom pad 54 is pulled upward at this time to make its lower surface separate from the clamping block 53, and then the bottom pad 54 is rotated to make the movable slider 55 rotate to a horizontal state and be located in the left and right horizontal grooves of the T-shaped guide groove 531, and the bottom pad 54 is pressed downward to make its lower surface fit to the upper surface of the upper tray 42, so as to facilitate the rapid adjustment of the bottom pad 54 to a horizontal state, so as to realize the rapid and accurate clamping and drilling of the outer ring surface of the shaft disk 9.

[0024] In this embodiment, a plurality of vertical plug rods 59 are fixedly provided at the position where the top of the clamping block 53 is staggered from the notch of the T-shaped guide groove 531, and a plurality of docking holes 541 are opened on the end surface of the bottom pad 54 close to the movable slider 55. When the bottom pad 54 is rotated to a vertical state at the top of the clamping block 53, the plurality of docking holes 541 and the plurality of vertical plug rods 59 are plugged into each other correspondingly; specifically, when the bottom pad 54 is rotated to a vertical state and is located on the upper surface of the clamping block 53, the plurality of vertical plug rods 59 will correspond to the plurality of docking holes 541, and then the bottom pad 54 is pressed downward, so that the plurality of vertical plug rods 59 is inserted into a plurality of docking sockets 541, thereby facilitating radial limiting and fixing of the vertical bottom pad 54, preventing the vertical bottom pad 54 from processing and fixing the cone sleeve 91 in a sliding state, and the bottom pad 54 rotates to a horizontal state, which will further affect the accuracy and safety of the cone sleeve 91 clamped by the vertical bottom pad 54; when the bottom pad 54 is pulled upward, the plurality of vertical insertion rods 59 will disengage from the plurality of docking sockets 541, thereby facilitating the bottom pad 54 to rotate to a horizontal state and push downward to fit onto the upper surface of the upper tray 42, thereby clamping and fixing the shaft disk 9.

[0025] In this embodiment, a sealing plug 6 is hermetically inserted into the top notch of the T-shaped guide groove 531. An extrusion plug 61 is formed on the lower surface of the sealing plug 6. The extrusion plug 61 is extruded and inserted into the left and right notches of the T-shaped guide groove 531, and its bottom abuts against the moving slider 55. Clamping holes are formed at the four corners of the sealing plug 6, and the clamping holes correspond to a plurality of vertical insertion rods 59. Specifically, when the bottom cushion block 54 is in a horizontal state and fits onto the upper tray 42, in order to prevent the bottom cushion block 54 from freely sliding up and down on the clamping block 53, the extrusion plug 61 and the sealing plug 6 are inserted into the T-shaped guide groove 531, and the bottom end of the extrusion plug 61 abuts against the moving slider 55, and the clamping holes will be clamped on the vertical insertion rods 59 to fix the sealing plug 6. This can not only prevent the metal powder generated by drilling from entering the T-shaped guide groove 531, but also prevent the moving slider 55 from freely sliding in the T-shaped guide groove 531.

[0026] In this embodiment, a segmented sealing film 7 is provided at the upper notch of the guiding square groove 422, and each segment of the sealing film 7 is respectively connected to the groove wall of the guiding square groove 422 and the guiding slider 52. Specifically, the design of the sealing film 7 can prevent the metal waste generated by drilling from entering the guiding square groove 422 and the radial groove 421, and will not interfere with the normal sliding of the guiding slider 52.

[0027] In this embodiment, a central hole 423 is also formed through the upper tray 42, and a sealing disc 8 is threadedly connected to the upper orifice of the central hole 423. Specifically, the design of the threadedly connected sealing disc 8 facilitates the maintenance of the components in the central hole 423.
