A flywheel inclined hole machining device

Abstract

The present invention discloses a flywheel inclined hole processing device, which relates to the field of flywheel processing. It includes a workbench, a base, a frame, a rotating frame, a rotating assembly, a positioning assembly and a mounting frame assembly. The rotating frame is rotatably connected to the frame. A drilling machine is provided inside the mounting frame assembly. A shielding spraying assembly is provided outside the drill bit of the drilling machine. During drilling, the processing surface is made to contact the shielding pipe, so that the shielding pipe can automatically retract, thus completely fitting the processing surface to form a complete protective space to prevent flying debris from scratching the staff. Since the shielding pipe fits the processing surface, when the cutting fluid is sprayed out from the water spraying port at the bottom of the shielding pipe, it can ensure that with the change of the processing depth and angle, the spraying position is always at the drill bit near the hole position, which is convenient for rapid cooling and prolongs the life of the drill bit. Link the adjustment of the inclination angle of drilling with the adjustment of the cutting fluid volume, and the amount of cutting fluid can be automatically changed according to the inclination angle.

Description

Technical Field

[0001] The present invention relates to the field of flywheel processing, and particularly to a flywheel inclined hole processing device. Background Art

[0002] There are few existing flywheel inclined hole processing devices, and the angle adjustment is inconvenient. Secondly, during general vertical hole processing, the chips are thrown out along the horizontal plane. However, during inclined hole processing, due to the inclination of the drill bit, the processed chips are easily thrown upward at a certain angle with the horizontal plane, which is more likely to scratch the operator. Therefore, it is necessary to block the waste chips. The existing blocking has poor adaptability and is difficult to fit the processing surface to form a full-range protection.

[0003] Secondly, during existing drilling, it is necessary to adjust the position of the cutting fluid nozzle according to the drilling position so that the cutting fluid is aligned with the drilling area. Therefore, it is necessary to frequently adjust when changing the drilling position, which is rather troublesome.

[0004] In addition, the larger the inclination angle, the larger the contact area between the drill bit and the processed object, and the easier the drill bit is to heat up. Therefore, it is necessary to adaptively adjust the amount of cutting fluid by changing the inclination angle. Most of the existing adjustments are achieved by manually adjusting the valve, which is prone to the situation of forgetting to adjust, resulting in overheating of the drill bit and reduced service life. When processing flywheels of different hardness and toughness materials, the processing resistance is different, and it is also necessary for workers to timely adjust the feed speed and rotation speed of the drill bit to avoid chipping and tool breakage. Summary of the Invention

[0009] Preferably, the rotating assembly includes a rotating motor and a rotating shaft.

The gear is fixedly connected to the rotating frame, and the worm gear meshes with a worm provided on the output shaft of the rotating motor. The worm is rotatably connected to the frame.

[0010] Preferably, the liquid supply device includes a piston cylinder. A piston rod is slidably connected within the piston cylinder. The left end of the piston rod passes through the piston cylinder and is fixedly connected to a rack. The rack meshes with the gear and is slidably connected to the frame.

[0013] By providing a detachable shielding and spraying assembly on the outer side of the drill bit, during drilling, the working surface can contact the shielding tube, causing the shielding tube to automatically retract, thus fully conforming to the working surface and forming a complete protective space to prevent flying debris from scratching the staff; since the shielding tube conforms to the working surface, when the cutting fluid is sprayed from the water spray openings at the bottom of the shielding tube, it can ensure that as the machining depth and angle change, the spraying position is always at the drill bit near the hole position, facilitating rapid cooling and extending the life of the drill bit.

[0014] Link the adjustment of the drilling inclination angle with the adjustment of the cutting fluid volume. The larger the angle, the larger the contact area, the more water inlets in the conducting state, and the larger the supply volume of the cutting fluid. Vice versa, the cutting fluid volume can be automatically changed according to the inclination angle. Brief Description of the Drawings

[0030] In this embodiment, the mounting frame assembly 8 includes a driving board 81 and a fixed frame 82. The fixed frame 82 is provided below the driving board 81.

A pressure sensor 86 is also provided between the driving board 81 and the fixed frame 82. The drilling machine 11 is fixedly connected inside the fixed frame 82.

[0031] In this embodiment, the shielding spraying assembly 9 includes a housing 91. The housing 91 is in the shape of a cylinder with openings at both ends. Inside the housing 91, there is an annular groove 911. At the bottom of the annular groove 911, a number of through holes 912 are equidistantly arranged. A shielding pipe 92 is slidably connected inside the through holes 912. The shielding pipe 92 is a tubular structure with an opening at the top and a closed bottom, and a limiting pipe head 921 is provided at its top.

[0033] In this embodiment, the rotating assembly 6 includes a rotating motor 61 and a rotating shaft 62. The rotating shaft 62 is rotatably connected to the frame 3. One end of the rotating shaft 62 is fixedly connected with a gear 63, and the other end is fixedly connected with a worm gear 64. The gear 63 is fixedly connected to the rotating frame 4. The worm gear 64 is meshed with a worm 65 arranged on the output shaft of the rotating motor 61. The worm 65 is rotatably connected to the frame 3. The worm gear 64 and the worm 65 can lock the angle after the drill bit is adjusted. The initial state of the rotating frame 4 is a vertical state with the drill bit downward, and it can be adjusted by a certain angle in the counterclockwise direction when adjusting the angle.

[0034] In this embodiment, the liquid supply device 7 includes a piston cylinder 71. A piston rod 72 is slidably connected inside the piston cylinder 71. The left end of the piston rod 72 passes through the piston cylinder 71 and is fixedly connected with a rack 73. The rack 73 is meshed with the gear 63 and is slidably connected to the frame 3. A number of water inlets 74 are provided on the peripheral wall of the piston cylinder 71, and a water outlet pipe 75 is provided at its right end. The water outlet pipe 75 is communicated with the water inlet pipe 913. The greater the clamping of the drilling direction with the vertical direction, the more the gear 63 rotates counterclockwise, and the piston rod 72 moves leftward, so that more water inlets 74 are opened, increasing the amount of cutting fluid.

[0035] Working process and its principle:

[0036] As shown Figure 2 in the figure, the initial state of the rotary frame 4 is a vertical state with the drill bit facing downwards, and it can be adjusted by a certain angle in the counterclockwise direction when adjusting the angle.

[0037] Step 1: Adjust the angle of the drill bit, and at the same time, make the liquid supply device 7 adjust the supply amount of the cutting fluid according to the rotation angle of the rotary frame 4.

[0038] The rotary motor 61 drives the worm 65 to drive the worm wheel 64 to rotate, so that the rotating shaft 62 rotates, and further makes the rotary frame 4 fixedly connected with the gear 63 rotate. The self-locking principle of the worm wheel 64 and worm 65 transmission is used to limit the adjusted angle.

[0039] When the angle between the axis of the drill bit and the vertical direction is relatively large, the drilling inclination angle is relatively large. As the inclination angle increases, that is, the rotary frame 4 rotates counterclockwise by a larger angle, the gear 63 drives the rack 73 to rotate to the left, making the piston rod 72 move away from the water outlet pipe 75. At this time, the piston at the left end of the piston rod 72 blocks fewer water inlet ports 74, so more cutting fluid is discharged into the water inlet pipe 913 through the water outlet pipe 75, then flows to the annular groove 911, and then is divided into each shielding pipe 92, and finally is sprayed onto the drill bit from the water spray port 923, realizing the automatic adjustment of the cutting fluid amount.

[0040] Step 2: Position the flywheel

[0041] After the drilling angle is determined, position and install the flywheel. The central hole of the flywheel is sleeved on the outside of the pneumatic expansion sleeve 56, and then the self-locking motor 51 is started to rotate slowly, so that the positioning pin 54 automatically inserts into the bolt holes around the central hole under the action of the second spring 55. Then the pneumatic expansion sleeve 56 internally supports and fixes the flywheel. Subsequently, through the action of the self-locking motor 51 and the linear module 12, the position to be drilled is adjusted to align with the drill bit.

[0042] Step 3: Drill the hole, and use the water spray folding assembly to spray the cutting fluid and shield the debris.

[0043] When the drill bit feeds, the output shaft of the electric cylinder 10 extends. The driving plate 81 acts on the fixed frame 82 through the first spring 85 and the pressure sensor 86 together, making the drill bit contact the end face of the flywheel and start drilling. There is a certain resistance during drilling. Since the elastic force of the first spring 85 is relatively large, the first spring 85 will be slightly compressed. The pressure sensor 86 detects the pressure between the driving plate 81 and the fixed frame 82. If the flywheel material is hard and the drilling speed cannot keep up with the feeding speed, the first spring 85 will be further compressed. When the pressure sensor 86 detects a large drilling resistance, it will automatically reduce the feeding speed and the drilling rotation speed, thereby reducing the drilling speed and avoiding excessive wear and chipping of the drill bit. The elastic force of the first spring 85 here is large enough to ensure that the pressure when the drill bit contacts the flywheel can meet the drilling requirements.

[0044] When the drill bit contacts the end face of the flywheel, the end face of the flywheel presses against the shielding tube 92. The shielding tube 92 that first contacts the end face of the flywheel retracts first, and the shielding tube 92 that later contacts the end face of the flywheel retracts later, finally forming a complete protective space that fits the end face of the flywheel to achieve the function of blocking debris. As the drill bit penetrates deeper, the shielding tube 92 will also gradually retract, but the bottom of the shielding tube 92 always contacts the end face of the flywheel, so the water spray port 923 can always be in a position aligned with the drill hole for spraying and cooling.

[0045] It avoids the problem that in traditional drilling, when drilling holes at different positions, it is necessary to frequently adjust the position of the nozzle for spraying cutting fluid.

[0046] As is known by technical common sense, the present invention can be implemented by other embodiments without departing from its spiritual essence or essential features. Therefore, the above-disclosed embodiments are illustrative in all aspects and are not the only ones. All changes within the scope of the present invention or within the scope equivalent to the present invention are encompassed by the present invention.
