Description

Technical Field

[0001] The present invention belongs to the technical field of punching equipment, and particularly relates to a conical sleeve type shaft disc punching device. Background Art

[0002] The shaft disc is a shaft sleeve part for the cooperative installation of the impeller and the transmission shaft. The shaft disc can bear the weight of the impeller, transmission torque, and can also reduce vibration and noise.

[0003] When processing the conical sleeve type shaft disc, it needs to be drilled to facilitate accurate use and installation; when the conical sleeve type shaft disc is drilled, punched or reamed, it needs to be clamped on the workbench, and then the drill bit drills it under the drive of the feed box. Therefore, if a conventional three-jaw chuck is used to clamp the shaft disc, due to the large diameter of the bottom of the shaft disc, effective clamping operation cannot be carried out on it. And when radially drilling the shaft disc, the existing fixture unit cannot adjust its clamping method to perform end face clamping on the conical sleeve cooperating with the shaft disc, which will affect the accurate and efficient drilling, punching or reaming of the shaft disc parts.

[0044] 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 making creative efforts belong to the scope of protection of the present invention.

[0045] 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 the 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 therefore should not be construed as a limitation of the present invention.

[0046] Please refer to Figures 1-7 As shown, the present invention is a conical sleeve type shaft disc drilling device, including 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 arrayed 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 provided 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, and the adjustable clamping block assembly 5 is used for clamping and positioning the shaft disc part 9 to be drilled.

[0047] 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 fixedly installed 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 and clamping on the shaft disc part 9. The moving guide rail on the workbench 1 can drive the clamping fixture 4 to move horizontally, 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. Moreover, 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, thus facilitating the 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.

[0048] 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 push rod 48 is slidably connected to the guide cylinder 47 through a sealing plug 6, and the outer end of the push 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 the 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 surface of the driven bevel gear 44.

[0049] Specifically, when the plurality of adjustable clamping block assemblies 5 in the circumferential array 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 push 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 surface 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 to accurately clamp the shaft disc member 9, preventing the adjustable clamping block assemblies 5 from loosening when the upper and lower two trays rotate, which affects the accurate and safe drilling 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 meshing bevel gears.

[0050] When it is necessary to adjust the plurality of adjustable clamping block assemblies 5 in the circumferential array, 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 push 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.

[0051] When the symmetrically left and right driven bevel gears 44 disengage from the driving bevel gear 45, the symmetrically front and rear driven bevel gears 44 continue to engage with the driving bevel gear 45. Thus, the rotation of the driving bevel gear 45 only drives the two front and rear groups of adjustable chuck assemblies 5 to slide away from or close to each other, enabling the two front and rear groups of adjusted adjustable chuck assemblies 5 to perform end clamping and fixing on the erected tapered kit 91. This facilitates radial drilling on the tapered kit 91, thereby improving the application range of the clamping fixture 4 of the present invention.

[0052] In this embodiment, the adjustable chuck assembly 5 includes a connecting guide sleeve 51. A connecting guide sleeve 51 is sleeved on each lead screw member 43 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 to 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 planar.

[0053] Specifically, the rotation of the lead screw member 43, through the cooperation of the ball nut pair and the connecting guide sleeve 51, drives the guiding slider 52 to slide in the guiding square groove 422. The cooperation between the guiding slider 52 and the guiding square groove 422 prevents it from rotating. Thus, the clamping block 53 drives the bottom cushion block 54 to slide easily on the upper tray 42, achieving clamping on 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, enabling it to accurately fit and clamp the shaft disc part 9 to be drilled. The bottom cushion block 54 can provide suspended support for the clamped shaft disc part 9, preventing the tip of the drill bit 31 from contacting the surface of the upper tray 42 and causing damage after the shaft disc part 9 is drilled by the drill bit 31. The surface of the bottom cushion block 54 is planar, 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.

[0054] 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 on the end face 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 ends of the support rod 57 are slidably connected to the vertical guide grooves 532 through bearings.

[0055] Specifically, since the vertical guide groove 532 is a blind groove design, when the bottom cushion block 54 slides upward to the top of the clamping block 53, the moving slider 55 will synchronously drive the mounting sleeve 56, the support rod 57, and the shaft rod 58 that is fitted with a bearing to slide to the top of the vertical guide groove 532. Then, the bottom cushion block 54 is rotated to make it in a vertical state. Since the T-shaped guide groove 531 penetrates upward through the top of the clamping block 53, the horizontally placed moving slider 55 will also be rotated to a vertical state synchronously. Then, the vertically placed bottom cushion block 54 is pressed downward so that its lower surface fits onto the upper surface of the clamping block 53. At this time, the inner side surface of the vertically placed bottom cushion block 54 will extend out of the inner side of the clamping block 53. Thus, the mutually approaching and vertically placed bottom cushion blocks 54 can accurately fit onto the two end faces of the vertically placed tapered sleeve 91 to achieve clamping treatment. Since the back of the T-shaped guide groove 531 is solid, when the vertically placed bottom cushion block 54 clamps the end of the tapered sleeve 91, the phenomenon of self-rotation of the bottom cushion block 54 will not occur, thereby improving the stability and safety of the vertically rotated bottom cushion block 54 clamping the vertically placed tapered sleeve 91. When it is necessary for the bottom cushion block 54 to rotate to a state perpendicular to the clamping block 53, at this time, the bottom cushion block 54 is pulled upward so that its lower surface is separated from the upper surface of the clamping block 53. Then, the bottom cushion block 54 is rotated so that the moving slider 55 rotates to a horizontal state and is located in the left and right horizontal grooves of the T-shaped guide groove 531. The bottom cushion block 54 is pressed downward so that its lower surface fits onto the upper surface of the upper tray 42, thereby facilitating the quick adjustment of the bottom cushion block 54 to a horizontal state and realizing the quick and accurate clamping and drilling treatment of the outer circumferential surface of the shaft disc part 9.

[0056] In this embodiment, a plurality of vertical insertion rods 59 are fixedly provided at positions where the top of the clamping block 53 is offset from the notch of the T-shaped guide groove 531. A plurality of docking insertion holes 541 are formed in the end face of the bottom cushion block 54 close to the moving slider 55. When the bottom cushion block 54 rotates to a vertical state on the top of the clamping block 53, the plurality of docking insertion holes 541 and the plurality of vertical insertion rods 59 are correspondingly inserted. Specifically, when the bottom cushion block 54 rotates to a vertical state and is located on the upper surface of the clamping block 53, at this time, the plurality of vertical insertion rods 59 will correspond to the plurality of docking insertion holes 541. Then, the bottom cushion block 54 is pressed downward so that the plurality of vertical insertion rods 59 are inserted into the plurality of docking insertion holes 541, thereby facilitating the radial limit fixation of the vertical bottom cushion block 54 and preventing the vertical bottom cushion block 54 from rotating during the sliding state when processing and fixing the tapered sleeve 91, and the bottom cushion block 54 rotates to a horizontal state, which will further affect the accuracy and safety of the vertically placed bottom cushion block 54 clamping the tapered sleeve 91. When the bottom cushion block 54 is pulled upward, at this time, the plurality of vertical insertion rods 59 will disengage from the plurality of docking insertion holes 541, thereby facilitating the rotation of the bottom cushion block 54 to a horizontal state and pushing it downward to fit onto the upper surface of the upper tray 42 for clamping and fixing the shaft disc part 9.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] 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.
