Technical Field
[0001] The present invention relates to the technical field of drilling processing equipment, and particularly relates to a drilling device for flywheel inclined holes with adjustable multi-equal division angles. Background Art
[0002] As one of the key parts of a press, the lubricating oil holes of a flywheel play a crucial role in ensuring good lubrication of the flywheel. Some flywheel lubricating oil holes are inclined holes, that is, multiple inclined holes distributed along the circumference of the flywheel at a certain inclination angle with respect to the axial direction of the flywheel. In the prior art, the processing of such holes is usually achieved by using an ordinary boring machine in combination with an auxiliary tool angle iron for clamping and drilling operations. The specific process is that after each inclined hole is processed, the clamping tool needs to be disassembled first, then the flywheel is lifted by a hoisting device and rotated to a suitable angle, and then re-calibrated before processing the next hole. Generally, a flywheel is evenly provided with 6 or 12 such inclined holes in the circumferential direction. In this way, to complete the processing of a flywheel part, the cumbersome disassembly and clamping operations need to be repeated 6 times or 12 times. This processing method has many disadvantages: the operation process is cumbersome and complex, greatly reducing the production efficiency; frequent lifting, clamping and calibration operations not only increase the labor intensity, but also are difficult to ensure the safety of operators; from the perspective of processing equipment resources, equipment such as a traveling crane and a large boring machine need to cooperate, resulting in a large occupation of equipment resources and high costs. The fundamental reason for these problems is that the existing processing methods lack a device that can efficiently position and perform multi-equal division precision indexing positioning, and cannot achieve precise processing of multiple inclined holes after one-time clamping. Summary of the Invention
[0003] In view of the need for efficient and precise positioning in processing flywheel inclined holes in the prior art, the present invention provides a drilling device for flywheel inclined holes with adjustable multi-equal division angles, which realizes one-time clamping and sub-precise positioning for processing multiple equally divided angle inclined holes provided on the flywheel surface.
[0004] The object of the present invention is achieved in this way. A drilling device for the inclined holes of a flywheel with adjustable multi-equal division angles includes a disk seat fixedly coaxial with a workpiece. A rotating table is rotatably installed on the disk seat. It is characterized in that a lead screw seat is fixedly arranged on the rotating table. A horizontal lead screw is horizontally arranged on the lead screw seat. One end of the horizontal lead screw extends outside the lead screw seat and is connected with a crank. A horizontal adjusting seat is slidably installed on the upper side of the lead screw seat through a slide rail mechanism. A nut cooperating with the horizontal lead screw is arranged on the lower side of the horizontal adjusting seat. A triangular seat is fixedly upward on one side of the horizontal adjusting seat. An inclined plane slide rail seat with adjustable inclination angle is hingedly arranged on the other side of the horizontal adjusting seat. An angle adjusting mechanism is arranged between the inclined plane slide rail seat and the triangular seat. A longitudinally penetrating U-shaped cavity is arranged in the inclined plane slide rail seat. A longitudinal slide rail is arranged on the outer edge of the longitudinal side opening of the U-shaped cavity and is slidably connected with a magnetic drill. The drilling direction of the magnetic drill is the same as the inclination direction of the inclined plane slide rail seat and inclines downward, and the inclination angle can be adjusted by the angle adjusting mechanism. A drilling feed mechanism is arranged in the U-shaped cavity for advancing and retreating the drilling depth of the magnetic drill.

[0005] For the drilling device of the inclined holes of a flywheel with adjustable multi-equal division angles of the present invention, the disk seat is fixedly coaxial with the workpiece. The angle of the drill bit of the magnetic drill for drilling is adjusted by the inclination angle of the inclined plane guide rail seat. The inclined plane guide rail seat is hingedly connected to the horizontal adjusting seat and the inclination angle of the hinge support on the horizontal adjusting seat is adjusted through the angle adjusting mechanism, so as to realize the adjustment of the angle of the drill bit for drilling the inclined hole. For the inclined holes with the same inclination angle distributed along the circumferential direction, only one adjustment is required, and after fixation, drilling processing with the same inclination can be realized multiple times; the horizontal adjusting seat can be horizontally adjusted along the rotating seat under the drive of the horizontal lead screw nut mechanism, so as to realize the radial adjustment and alignment of the drilling position. Therefore, the beneficial effects of the present invention are as follows: The drilling device of the inclined holes of a flywheel with adjustable multi-equal division angles of the present invention can be directly fixedly coaxial on the surface of the flywheel workpiece to be processed. After adjusting the inclination angle of the processed inclined hole through the angle adjustment mechanism, through the rotation of the rotating disk, multiple inclined holes distributed circumferentially can be processed. Through the translational movement of the horizontal adjusting seat, the processing alignment position of the inclined hole can be accurately aligned, realizing one-time positioning adjustment and continuous processing of multiple inclined holes in the circumferential direction, greatly reducing the efficiency of clamping, positioning and alignment for processing multiple inclined holes.

DETAILED DESCRIPTION OF THE INVENTION
[0020] As Figures 1 - 3As shown in the figure, it is a drilling device for the flywheel inclined hole with adjustable multi-equal division angle of the present invention, including a disc seat 1 coaxially fixed with the workpiece. A rotary table 2 is rotatably installed on the disc seat 1. A lead screw seat 3 is fixedly arranged on the rotary table 2. A horizontal lead screw 10 is horizontally arranged on the lead screw seat 3. One end of the horizontal lead screw 10 extends outside the lead screw seat 3 and is connected with a crank 9. Horizontal guide rails 301 are arranged on both side edges on the upper side of the lead screw seat 3 and are connected and slid with a horizontal adjustment seat 4. A nut cooperating with the horizontal lead screw 10 is arranged on the lower side of the horizontal adjustment seat 4. A number of locking bolts 22 for locking the slide rail mechanism are arranged on the side of the horizontal guide rail 301 and the slide rail connection of the horizontal adjustment seat 4; One side of the horizontal adjustment seat 4 is fixedly upward with a triangular seat 5. The other side of the horizontal adjustment seat 5 is hinged and connected with an inclined plane slide rail seat 16 with an adjustable inclination angle that can rotate around the hinge axis through a hinge seat and a hinge axis. An angle adjustment mechanism is arranged between the inclined plane slide rail seat 16 and the triangular seat 5. A longitudinally penetrating U-shaped cavity is arranged in the inclined plane slide rail seat 16. A longitudinal slide rail 1601 is arranged on the outer edge of the longitudinal side port of the U-shaped cavity and is slidably connected with a magnetic drill 15. The drilling direction of the magnetic drill 15 is the same as the inclination direction of the inclined plane slide rail seat 16 and is inclined downward, and the inclination angle can be adjusted through the angle adjustment mechanism. A drilling feed mechanism 17 is arranged in the U-shaped cavity for advancing and retreating the drilling depth of the magnetic drill 15. The center line of the magnetic drill bit 12 and the center line of the horizontal lead screw 10 are located in the same vertical plane passing through the central axis of the rotary table 2.
[0021] To facilitate the rotation of the rotating table on the disc base to switch different inclined hole positions, a T-shaped ring groove 102 is provided on the upper surface of the disc base 1. At the position corresponding to the T-shaped ring groove 102 on the lower side of the rotating table 2, a T-shaped slider 18 is provided in a matching manner. The slider at the lower part of the T-shaped slider 18 is slidably engaged with the T-shaped ring groove 102. The central rod part of the T-shaped slider 18 is penetrated and installed on the rotating table 2 and locked by a nut. When the nut is loosened, the T-shaped slider 18 can slide along the T-shaped ring groove 102. When the nut is tightened, the T-shaped slider 18 is locked with the T-shaped ring groove 102, and the relative position of the rotating table 2 and the disc base 1 is locked. A number of radial guide grooves 101 are arranged at equal angular intervals in the circumferential direction of the disc base 2 on the outer circumference of the ring groove 102. A longitudinal through hole is also provided on the rotating table directly below the horizontal lead screw 10. A steel ball 25 is pressed and installed in the longitudinal through hole through a screw rod 23 and a compression spring 24. A nut is screwed on the screw rod. The disc base 1 is respectively provided with pits 103 that elastically snap with the steel ball 25 corresponding to the longitudinal through hole and in the same radial direction as the radial guide groove 101. The pits 103 and the radial guide grooves 101 are located in the same radial direction in a one-to-one correspondence. During the rotation of the rotating table 2, when the steel ball 25 passes through the position of the pit 103 and snaps with the pit 103, the rotating table 2 stops rotating. At this time, the drill bit 12 of the magnetic drill exactly corresponds to the position of the radial guide groove 101 in the same diameter direction. By rotating the rotating table 2 in sequence, the drill bit 12 can be respectively positioned at the positions of each radial guide groove 101, and then the radial position of the drill bit 12 is adjusted by the horizontal lead screw 10, and the inclined holes at the corresponding positions of each radial guide groove can be drilled respectively.
[0022] To facilitate the fixation and angle adjustment of the inclined plane slide rail seat 16, the triangular seat 5 is a right-angled triangular support. One of the right-angled parts is fixed to the horizontal adjustment seat 4, and the other right-angled part is vertically arranged. An angle adjustment mechanism is connected to the vertical right-angled part of the triangular seat 4. Specifically, the angle adjustment mechanism includes a screw rod 8. One end of the screw rod 8 is hingedly connected to the corresponding side surface of the inclined plane slide rail seat 8 through a hinge seat and a hinge shaft. The other end of the screw rod 8 is provided with a through hole corresponding to the vertical right-angled part of the triangular seat 5. The screw rod 8 passes through the other side of the through hole, and adjusting nuts 6 and locking nuts 7 are respectively screwed on both sides. One side of the lower part of the inclined plane slide rail seat 16 close to the triangular seat 5 is hingedly connected to the horizontal adjustment seat 7. In this way, the inclination angle of the inclined plane guide rail seat 16 can be adjusted by adjusting the screwing position of the adjusting nut and the screw rod. After the adjustment is in place, the position of the screw rod is locked by the locking nut, thereby locking the inclination angle of the inclined plane slide rail seat 16.
[0023] To facilitate the intuitive observation and control of the adjustment angle of the inclined plane slide rail seat 16, a scale disk 11 for measuring the inclination angle of the inclined plane slide rail seat 16 is provided on the side surface of the horizontal adjustment seat 4 corresponding to the hinged part of the inclined plane slide rail seat 16 and the horizontal adjustment seat 4. A follower pointer 20 is provided on the inclined plane slide rail seat 16. By reasonably setting the positions of the scale disk 11 and the pointer 20, the change in the inclination angle of the inclined plane slide rail seat can be intuitively observed.
[0024] To facilitate the control of the drilling and withdrawal of the magnetic drill 15, a slide plate 14 is slidably connected to the longitudinal slide rail 1601 of the inclined slide rail seat 16. The magnetic drill 15 is fixed to the slide plate 14, so that the magnetic drill 15 moves synchronously with the slide plate 14. The drilling feed mechanism includes a longitudinal lead screw 1701 rotatably installed in the U-shaped cavity of the inclined slide rail seat 16. A nut seat 1702 is cooperatively connected to the longitudinal lead screw 1701. A nut for cooperating with the longitudinal lead screw is provided inside the nut seat 1702. Under the rotation of the longitudinal lead screw 1701, the nut seat 1702 can move up and down along the U-shaped cavity. The part of the nut seat 1702 facing the longitudinal side opening of the U-shaped cavity is fixedly connected to the slide plate 14. A bracket 13 for supporting the drill bit 12 part of the magnetic drill 15 is further provided on the slide plate 14.
[0025] To facilitate the realization of a smooth drilling feed movement, two upper and lower bearing seats for rotatably supporting the longitudinal lead screw 1701 are provided in the U-shaped cavity, namely the upper bearing seat 1704 and the lower bearing seat 1703 respectively provided above and below the nut seat. The longitudinal lead screw 1701 is rotatably installed in the bearing seats through bearings respectively. A worm gear box for driving the lead screw to rotate is provided at the upper end of the longitudinal lead screw 107. A worm gear mechanism is provided inside the worm gear box. The worm gear shaft of the worm gear mechanism is coaxially connected to the extended end of the longitudinal lead screw 1701. A worm gear 1705 is installed on the worm gear shaft. A worm 1706 meshing with the worm gear 1705 is cooperatively provided inside the worm gear box. The shaft end of the worm 1706 horizontally extends outside the worm gear box and is connected with a hand wheel 1707. By manually rotating the hand wheel 1707, the deceleration movement of the worm gear and the longitudinal lead screw can be driven, and a smooth drilling feed movement during drilling can be realized.
[0026] To quickly withdraw the drill bit from the drilled inclined hole after the drilling is completed, a synchronous gear 1708 is fixed to the upper end of the worm gear shaft. A gear shaft meshing with the synchronous gear 1708 is rotatably installed on the top cover of the worm gear box. A driving gear 1709 meshing with the synchronous gear is cooperatively provided on the gear shaft. The synchronous gear 1708 and the driving gear 1709 drive the end of the gear shaft in the same ratio and extend above the top cover of the worm gear box and are fixed with a pin shaft hand wheel 1710. A hand wheel rod 1711 is provided on the pin shaft hand wheel 1710. When the drilling reaches the drilling depth, the pin shaft hand wheel can be rotated reversely through the hand wheel rod 1711, driving the rotation of the driving gear 1709 and the synchronous gear 1708, realizing the rapid withdrawal of the longitudinal lead screw 1701 from the inclined hole, so as to realize the slow feed and fast withdrawal drilling feed and withdrawal movement during drilling.
[0027] For the drilling device of the flywheel inclined hole with adjustable multi-equal division angle, after the disc seat 1 is fixed coaxially with the workpiece, the magnetic drill 15 is magnetically fixed on the slide plate 14. At this time, the drill bit points to the surface of the workpiece. According to the required inclination of the drilled hole, first adjust the inclination angle of the inclined plane slide rail seat 16 through the adjusting nut 6 of the angle adjusting mechanism, which also synchronously adjusts the angle of the drilling direction of the drill bit 12 of the magnetic drill. The inclination angle can be visually observed through the needle indicator 20 and the scale disk 11. After the angle adjustment is in place, lock the supporting angle of the inclined plane slide rail seat 16 by tightening the locking nut 7 on the locking screw 8; then adjust the rotation angle of the rotating table 2. When the steel ball rotating together with the rotating table 2 is buckled with the concave pit, there is a clicking sound of the elastic buckle. At this time, the angular position of the rotating table 2 relative to the disc seat is elastically fixed. Then tighten the nut on the T-shaped slider 18 to lock the rotating table 2. Align the drill bits 12 of the magnetic drills in the same diameter direction to the center line of the radial guide groove. Then rotate the horizontal lead screw 10 through the manual crank 9 to translate the position of the horizontal adjusting seat 4 so that the head position of the drill bit 12 is aligned with the position of the first inclined hole to be machined. After alignment, tighten each locking bolt 22 to lock the horizontal adjusting seat and the position on the lead screw seat 3; then start the drilling process and evenly rotate the handwheel 1708 manually to achieve a slow and stable drilling feed movement. When the drilling depth is reached, the drill bit stops. Rotate the pin shaft handwheel 1710 in the reverse direction through the handwheel rod 1711 to drive the rotation of the driving gear 1709 and the synchronous gear 1708, so as to quickly withdraw the longitudinal lead screw 1701 from the inclined hole, thus realizing the drilling feed and withdrawal movement of slow feed and fast withdrawal. Thus, the positioning and drilling process of one inclined hole is completed; then retract the drill bit 12 of the magnetic drill upward, loosen the nut on the T-shaped slider 18 to release the rotating table 2 and the disc seat 1, rotate the angle of the rotating table 2 so that the steel ball 25 is aligned with the next adjacent concave pit 103 and elastically buckle, and then tighten the nut on the T-shaped slider 18 to lock the rotating table 2 again, complete the adjustment and positioning of the angle of the second adjacent inclined hole, and then perform drilling processing according to the above drilling process, and repeat the above process to complete the processing of all inclined holes. Realize the one-time fixation of the device, adjust it in batches, and complete the processing of all inclined holes in the circumferential direction of a workpiece, greatly improving the efficiency of clamping, positioning and alignment for the processing of multiple inclined holes.
