Description

Technical Field

[0001] This utility model relates to the field of output shaft positioning plate processing technology, specifically a drilling machine for processing output shaft positioning plates. Background Technology

[0002] Output shaft positioning plates are crucial components in mechanical transmission systems. Their primary function is to precisely position and fix the output shaft, ensuring the stability and reliability of the transmission system. In various mechanical equipment, such as automotive gearboxes and industrial transmission devices, the machining accuracy of the output shaft positioning plate directly affects the overall performance of the equipment. In particular, the quality of the drilling process plays a key role in the assembly accuracy of the positioning plate with other components and the operating efficiency of the transmission system. In existing technologies, drilling equipment for output shaft positioning plates typically includes a base, an adjustable drill bit, and a clamping mechanism. The workpiece is placed on the worktable of the drilling machine and fixed in position by the clamping mechanism. The drill bit completes the drilling operation under the action of the drive device. Although such equipment has basic automated clamping and drilling functions, the unloading process after workpiece machining still relies on manual labor to remove the drilled positioning plate from the clamping mechanism. The entire process requires continuous manual intervention. However, existing technologies have some problems in practical applications. Manual unloading increases the labor intensity of operators, leading to low production efficiency and difficulty in matching the processing rhythm of high-speed drilling equipment. Therefore, we propose a drilling machine for processing output shaft positioning plates. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The drilling machine for processing the output shaft positioning plate has the following advantages: The unloading mechanism uses the paddles on both sides of the mounting plate to act on the drive rod and the displacement plate respectively, so that the arc-shaped push plate pushes the drilled output shaft positioning plate to the left. At the same time, the arc-shaped positioning plate moves down to make room, allowing the output shaft positioning plate to slide out along the inclined section of the track. After that, the mechanism resets and prepares for the next loading, realizing automatic unloading, reducing manual intervention and improving processing efficiency. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-8This embodiment provides a technical solution: a drilling machine for processing output shaft positioning plates, including a base 1. A control switch group 14 is provided on the front side of the base 1. The input end of the control switch group 14 is electrically connected to an external power source. An adjustable drill bit 12 is provided on the upper end of the base 1 (drilling the output shaft positioning plate will generate debris, which is removed by an external dust extraction device). A track 3 is provided on the upper side of the base 1 (the bottom wall of the left half of the track 3 has an inclined structure with the left bottom higher than the right). A symmetrically distributed arc-shaped clamping frame 6 is provided on the right end of the track 3 (the center point of the complete circular path formed by the inner arc surfaces of the two arc-shaped clamping frames 6 always coincides with the central axis of the drill bit 12). The front and rear sides of the bottom wall of the right end of the track 3 are connected to the upper side of the base 1. The base 1 has sliding grooves 5 on both the front and rear sides. The lower ends of the arc-shaped clamping frames 6 are slidably connected to the two adjacent upper and lower corresponding sliding grooves 5 on the lower side. A bidirectional lead screw 7 is rotatably connected between the front and rear inner walls of the base 1. The threaded ends of the bidirectional lead screw 7 on both the front and rear sides are threadedly connected to the lower ends of the adjacent arc-shaped clamping frames 6 on the upper side (a bellows is provided between the front and rear inner walls of the base 1 and the lower outer side of the adjacent arc-shaped clamping frames 6 on the inner side. The bidirectional lead screw 7 is located inside the bellows. The bellows provides external protection for the bidirectional lead screw 7 while ensuring its sealing and lubrication). A motor 8 is installed on the front side of the base 1. The output shaft of the motor 8 is fixedly connected to the center of the front end face of the bidirectional lead screw 7. The input end of the motor 8 is electrically connected to the output end of the control switch group 14.A mounting bracket 9 is installed on the upper side of the base 1. A guide slide post 10 is provided on the top wall of the mounting bracket 9. The outer arc surface of the guide slide post 10 is slidably connected to the housing 11. The drill bit 12 is rotatably connected to the bottom wall of the housing 11 (an external motor is installed inside the housing 11, and the output shaft of the external motor is fixedly connected to the center of the upper end face of the drill bit 12; the input end of the external motor is also electrically connected to the output end of the control switch group 14). An electric cylinder 13 is installed on the upper side of the mounting bracket 9, and the telescopic end of the electric cylinder 13 penetrates through the mounting bracket 9. The upper end is fixedly connected to the upper side of the housing 11. The input end of the electric cylinder 13 is electrically connected to the output end of the control switch group 14. A through hole 4 is opened on the bottom wall of the right end of the track 3 (during processing, the worker places the output shaft positioning plate on the right end of the track 3 to block the through hole 4, and the through hole 4 provides space for the drill bit 12 to move down). First, the worker places the output shaft positioning plate that needs to be drilled between the arc-shaped push plate 201 and the arc-shaped positioning plate 202. The inner arc surfaces of the arc-shaped positioning plate 202 and the arc-shaped push plate 201 temporarily restrict the positioning of the output shaft. The left and right positions of the plate are adjusted, and then the control switch group 14 starts the motor 8. The output shaft of the motor 8 drives the double-sided lead screw 7 to rotate. The threads at both ends of the double-sided lead screw 7 drive the front and rear arc-shaped clamping frames 6 to slide along the slide groove 5. The inner arc surfaces of the two arc-shaped clamping frames 6 clamp the output shaft positioning plate, thereby maintaining the stable position of the output shaft positioning plate. The control switch group 14 extends the telescopic end of the electric cylinder 13, pushing the machine housing 11 down along the guide slide column 10. The drill bit 12 descends accordingly. The external motor inside the machine housing 11 is powered by... The control switch assembly 14 activates the external motor, driving the drill bit to rotate at high speed and drill a hole in the output shaft positioning plate. When the drill bit 12 penetrates the output shaft positioning plate, it enters the through hole 4, preventing damage to the bottom wall of the track 3. After drilling the output shaft positioning plate, the control switch assembly 14 retracts the telescopic end of the electric cylinder 13, pulling the motor housing 11 upwards along the guide slide 10. The drill bit 12 rises accordingly and moves away from the output shaft positioning plate, facilitating drilling. The system also includes a feeding mechanism 2. The unloading mechanism 2 includes an arc-shaped push plate 201 and an arc-shaped positioning plate 202. The arc-shaped push plate 201 and the arc-shaped positioning plate 202 are respectively located at the right end of the track 3 (when the arc-shaped push plate 201 and the arc-shaped positioning plate 202 are in their initial positions, their inner arc surfaces are on the same circular path, and the center point of this circular path coincides with the central axis of the drill bit 12). The arc-shaped positioning plate 202 is located to the left of the arc-shaped push plate 201. Both the arc-shaped push plate 201 and the arc-shaped positioning plate 202 are used in conjunction with the arc-shaped clamping frame 6. The unloading mechanism 2 also includes a clearance opening 203, a clearance groove 204, a sliding column 205, a drive rod 206, a displacement plate 208, and a mounting column 209. The clearance opening 203 is respectively opened at the right end of the track 3. The bottom wall and the upper side wall of the base 1 are connected by sliding columns 205, which are respectively set on the inner right side wall of the base 1. A drive rod 206 is slidably connected between the two sliding columns 205. The upper end of the drive rod 206 passes through two clearance slots 203 and is fixedly connected to the lower side of the arc-shaped push plate 201. Clearance slots 204 are respectively opened on the bottom right wall of the track 3 and the upper side wall of the base 1. The top wall of the base 1 is provided with a mounting column 209. The outer arc surface of the mounting column 209 is slidably connected to a displacement plate 208. The upper end of the displacement plate 208 passes through two clearance slots 204 and is fixedly connected to the lower side of the arc-shaped positioning plate 202. The feeding mechanism 2 also includes a sprocket 207, a rectangular frame 210, a mounting plate 211, a sprocket 212 and a rotating shaft 213. The sprocket 207 is opened at the lower end of the drive rod 206. On the front side, a rectangular frame 210 is located at the lower end of the displacement plate 208. A mounting plate 211 is rotatably connected to the rear inner wall of the base 1 via a rotating shaft 213. A deflector 212 is provided at the left end of the front side and the right end of the rear side of the mounting plate 211. The rear end of the right deflector 212 is located inside the deflector groove 207, and the front end of the left deflector 212 is located inside the rectangular frame 210. The feeding mechanism 2 also includes a motor 214, which is mounted on the rear side of the base 1. The output shaft of the motor 214 is fixedly connected to the center of the rear end face of the rotating shaft 213. The input end of the motor 214 is electrically connected to the output end of the control switch group 14. After the output shaft positioning plate is drilled, the control switch group 14 is operated to start the motor 214. The rotating shaft 213 rotates 90 degrees counterclockwise, causing the mounting plate 211 to rotate with it. The two deflector pins 212 on either side of the mounting plate 211 act on the slot 207 of the drive rod 206 and the rectangular frame 210 of the displacement plate 208, respectively. The right deflector pin 212 pushes the drive rod 206 to slide to the left along the sliding column 205. The arc-shaped push plate 201 moves synchronously with the drive rod 206 and pushes the drilled output shaft positioning plate to the left. Simultaneously, the left deflector pin 212 causes the displacement plate 208 to slide along the mounting column 209, and the arc-shaped positioning plate 202 moves downward to make way for the output shaft positioning plate. The output shaft positioning plate slides off the inclined section of the left side of the track 3. Then, the motor 214 reverses 90 degrees, and the deflector pin 212 causes the drive rod 206 and the displacement plate 208 to reset.The arc-shaped positioning plate 202 and the arc-shaped push plate 201 return to their initial positions, ready for the next loading, reducing manual intervention and improving processing efficiency.

[0016] The working principle of the drilling machine for processing output shaft positioning plates provided by this utility model is as follows: First, the worker places the output shaft positioning plate to be drilled between the arc-shaped push plate 201 and the arc-shaped positioning plate 202. The inner arc surfaces of the arc-shaped positioning plate 202 and the arc-shaped push plate 201 temporarily restrict the left and right positions of the output shaft positioning plate. Then, the control switch group 14 starts the motor 8. The output shaft of the motor 8 drives the bidirectional lead screw 7 to rotate. The threads at both ends of the bidirectional lead screw 7 drive the arc-shaped clamping frames 6 on the front and rear sides to slide along the slide groove 5. The inner arc surfaces of the two arc-shaped clamping frames 6... The output shaft positioning plate is clamped to maintain its stable position. The control switch group 14 extends the telescopic end of the electric cylinder 13, pushing the housing 11 downwards along the guide slide column 10. The drill bit 12 descends accordingly. The external motor inside the housing 11 is started by the control switch group 14, and the output shaft of the external motor drives the drill bit to rotate at high speed, drilling a hole in the output shaft positioning plate. When the drill bit 12 penetrates the output shaft positioning plate, it can enter the interior of the through hole 4, preventing damage to the bottom wall of the track 3. After drilling the output shaft positioning plate, the control switch group 14... 4. The telescopic end of the electric cylinder 13 retracts, pulling the motor housing 11 upward along the guide slide column 10. The drill bit 12 rises accordingly and moves away from the output shaft positioning plate. Then, the control switch group 14 starts the motor 214, driving the rotating shaft 213 to rotate 90 degrees counterclockwise. The mounting plate 211 rotates with the rotating shaft. The two deflector pins 212 on both sides of the mounting plate 211 act on the deflector groove 207 of the drive rod 206 and the rectangular frame 210 of the displacement plate 208, respectively. The deflector pin 212 on the right pushes the drive rod 206 to slide to the left along the slide column 205. The arc-shaped push plate 201 moves with the drive rod. 206 synchronously shifts and pushes the drilled output shaft positioning plate to the left. At the same time, the left-side pivot 212 drives the displacement plate 208 to slide along the mounting column 209, and the arc-shaped positioning plate 202 moves down to make way for the output shaft positioning plate. The output shaft positioning plate slides out of the track 3 along the inclined part of the left section of the track 3. Then the motor 214 reverses 90 degrees, the pivot 212 drives the drive rod 206 and the displacement plate 208 to reset, and the arc-shaped positioning plate 202 and the arc-shaped push plate 201 return to their initial positions, ready for the next loading, reducing manual intervention and improving processing efficiency.

[0017] It is worth noting that the electric motors 214 and 8 disclosed in the above embodiments are recommended to be servo motors of the MINASA6 series, the electric cylinder 13 is recommended to be of the THKRH series, the external motor that drives the drill bit 12 to rotate is recommended to be of the 1LG0 series, and the control switch group 14 is provided with control buttons that correspond one-to-one with the electric motors 214, 8, 13 and the external motor that drives the drill bit 12 to rotate and are used to control their switching.
