Description

Technical Field

[0001] The present invention relates to the field of drilling facilities, and particularly to a drilling machine for processing brake handles that is convenient for positioning. Background Art

[0002] A brake handle usually refers to an operating device installed on means of transportation such as bicycles, electric vehicles, and motorcycles, used to control the braking system to achieve the function of decelerating or stopping. When the brake handle is gripped, force is transmitted through the brake cable to the braking device, causing the brake pads or brake shoes to contact the wheels or brake discs, thereby generating frictional force to slow down or stop the movement of the vehicle. Some modified brake handles are widely used because of their beautiful appearance.

[0003] When processing modified brake handles, for the convenience of assembly, drilling facilities are often used to drill holes in the brake handles so that they can be assembled using these holes later. However, due to the special shape of the brake handles, traditional positioning facilities are not conducive to positioning them during processing, resulting in the phenomenon that it is not convenient to drill the brake handles. Summary of the Invention

[0004] The purpose of the present invention is to solve the drawbacks existing in the background art, and to propose a drilling machine for processing brake handles that is convenient for positioning.

[0005] To achieve the above object, the technical solution adopted by the present invention is: a drilling machine for processing brake handles that is convenient for positioning, including a frame. The middle part of the frame is connected with a drilling table. The upper middle part of the drilling table is fixedly installed with a drilling support seat. The upper end surface of the drilling support seat is arranged in a stepped shape. A positioning seat is installed on the upper end of the drilling table near the side of the drilling support seat. The positioning seat is arranged obliquely. A positioning groove is opened in the middle of the upper end of the positioning seat. A handle fixing member is arranged at the rear end of the positioning seat. A drilling member is installed on the upper part of the front end of the frame.

[0006] Preferably, the drilling member includes a lifting seat installed on the upper part of the front end of the frame. A carrier is fixedly installed on the front end surface of the lifting seat. A driving shaft is rotatably installed inside the carrier. A drill bit is coaxially installed at the lower end of the driving shaft. The drill bit corresponds to the upper part of the drilling support seat.

[0007] Preferably, a second servo motor is fixedly installed on the upper end of the carrier. Pulley wheels are coaxially inlaid on the output end of the second servo motor and the outer surface of the driving shaft. A synchronous belt is connected between the two pulley wheels. Two guide seats are symmetrically inlaid on the rear end surface of the lifting seat. Two guide rails are symmetrically fixedly installed on the upper part of the front end of the frame. The guide seats are slidably installed on the guide rails.

[0008] Preferably, a threaded rod is arranged between the two guide rails. Both ends of the threaded rod are rotatably installed with rod seats, and the ends of the rod seats are fixed to the machine frame. The lifting seat is screwed onto the outer surface of the threaded rod. A first servo motor is fixedly installed at the upper end of the machine frame, and the output end of the first servo motor is connected to the threaded rod.

[0009] Preferably, the handle fixing member includes a carrier plate elastically installed at the rear end of the positioning seat. A guide wheel is connected to the rear end of the carrier plate. A connecting and fixing frame is fixedly installed on the side surface of the lifting seat. A pushing frame is fixedly installed at the end of the connecting and fixing frame. The lower end of the pushing frame is inclined. The guide wheel is attached to the lower end of the pushing frame. Two pressing frames are fixedly installed at the upper end of the carrier plate, and a positioning column is connected to the end of the carrier plate.

[0010] Preferably, guide sleeves are fixedly installed at the upper edge of the positioning seat. The pressing frames slide through the inside of the guide sleeves. A column seat is inlaid on the outer surface of the positioning column, and the end of the column seat is fixed to the carrier plate. The edge of the end of the positioning column is beveled. The upper and lower edges of the end of the pressing frame are arc-shaped. Wheel seats are installed at both ends of the guide wheel, and the ends of the wheel seats are fixed to the carrier plate.

[0011] Preferably, two bearing holes are symmetrically opened at the rear end of the positioning seat. A guide post is coaxially inlaid at the front end inside the bearing hole, and the guide post extends out from the inside of the bearing hole. The carrier plate is slidably installed on the outer surface of the guide post. A limit cap is coaxially inlaid at the end of the guide post, and the limit cap is attached to the rear end of the carrier plate. A return spring is wound around the outside of the guide post. One end of the return spring is fixed to the front end of the carrier plate, and the other end of the return spring is fixed to the front end inside the bearing hole.

[0012] Preferably, two extending frames are symmetrically and obliquely extended at the lower end of the drilling table. A frame seat is fixedly installed at the end of the extending frame, and the end of the frame seat is fixed to the machine frame. A support frame extends from the lower end of the positioning seat, and the end of the support frame is fixed to the drilling table.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By using the inclined positioning seat, the brake handle can be placed on the positioning seat. At this time, the brake handle fits into the positioning groove on the positioning seat to position the brake handle, so that the drilling end of the brake handle can be horizontally attached to the drilling support seat. At the same time, the stepped portion of the drilling support seat presses against the corner of the brake handle to position it. In this way, the drilling end of the brake handle can be positioned below the drill bit for drilling. The positioning process is simple, which effectively facilitates the drilling process of the brake handle.

[0015] 2. Through the moving pushing frame, the guide wheel can roll along the inclined section of the pushing frame to push the carrier plate, enabling the carrier plate to slide on the guiding columns, thereby driving the pressing frame to move, so that the pressing frame can press on the upper end of the brake handle to fix it in the positioning groove. Subsequently, the carrier plate continues to move, allowing the positioning post to fit into the hole at the end of the brake handle, so as to firmly fix the brake handle through the pressing frame and the positioning post, preventing it from shaking during the drilling process, ensuring the normal progress of the drilling operation. At the same time, when the lifting seat drives the drill bit to move downward for drilling, it will synchronously drive the pushing frame to move downward to automatically complete the fixation of the brake handle. This process does not require manual fixation by workers, effectively facilitating the use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0024] As Figures 1-6 shown, a drilling machine for processing a brake handle that is convenient for positioning includes a frame 1. A drilling table 2 is connected to the middle of the frame 1. A drilling support seat 5 is fixedly installed in the middle of the upper end of the drilling table 2. The drilling table 2 serves to carry the drilling support seat 5. The upper end surface of the drilling support seat 5 is arranged in a stepped shape, which can adapt to the shape of the end of the brake handle 34 to be drilled, so that when drilling, it can support the brake handle 34. At the same time, the stepped part of the drilling support seat 5 can also be pressed against the corner of the brake handle 34 to position it, so that the end of the brake handle 34 to be drilled is positioned below the drill bit 29. A positioning seat 4 is installed on the upper end of the drilling table 2 near the side of the drilling support seat 5. The positioning seat 4 is inclined, which can adapt to the slope of the brake handle 34 itself. After the brake handle 34 fits into the positioning groove 19 on the positioning seat 4, the end of the brake handle 34 to be drilled can be horizontally attached to the drilling support seat 5 to ensure that the subsequent drilled hole wall can be vertical. A positioning groove 19 is opened in the middle of the upper end of the positioning seat 4. A handle fixing member is provided at the rear end of the positioning seat 4. A drilling member is installed on the upper part of the front end of the frame 1.

[0025] The drilling member includes a lifting seat 7 installed on the upper part of the front end of the frame 1. The lifting seat 7 serves to drive the drill bit 29 to move up and down. A carrier 6 is fixedly installed on the front end surface of the lifting seat 7. A drive shaft 30 is rotatably installed inside the carrier 6. The carrier 6 serves to carry the drive shaft 30. The lower end of the drive shaft 30 is coaxially installed with the drill bit 29. The drive shaft 30 serves to drive the drill bit 29 to rotate. The drill bit 29 corresponds to the upper part of the drilling support seat 5.

[0026] A second servo motor 24 is fixedly installed at the upper end of the carrier 6. The second servo motor 24 serves to drive the drive shaft 30 to rotate. A pulley 22 is coaxially inlaid on the output end of the second servo motor 24 and the outer surface of the drive shaft 30. A synchronous belt 23 is connected between the two pulleys 22. The pulley 22 serves to connect the synchronous belt 23. The synchronous belt 23 serves to transmit power. Two guide seats 26 are symmetrically inlaid on the rear end surface of the lifting seat 7. Two guide rails 25 are symmetrically fixedly installed on the upper part of the front end of the frame 1. The guide seats 26 and the guide rails 25 serve to guide the lifting seat 7. The guide seats 26 are slidably installed on the guide rails 25.

[0027] A threaded rod 28 is arranged between two guide rails 25. The threaded rod 28 functions to drive the lifting seat 7 to move up and down. Rod seats 31 are rotatably installed at both ends of the threaded rod 28. The rod seats 31 function to support the threaded rod 28. The ends of the rod seats 31 are fixed to the frame 1. The lifting seat 7 is screwed onto the outer surface of the threaded rod 28. A first servo motor 8 is fixedly installed at the upper end of the frame 1. The output end of the first servo motor 8 is connected to the threaded rod 28. The first servo motor 8 functions to drive the threaded rod 28 to rotate. When the first servo motor 8 works to drive the threaded rod 28 to rotate, the lifting seat 7 screwed onto the threaded rod 28 moves downward. At this time, the guide seat 26 slides on the guide rail 25 to guide the downward-moving lifting seat 7, and the downward-moving lifting seat 7 drives the drill bit 29 and the pushing frame 9 to move downward respectively.

[0028] The fixing part includes a carrier plate 10 elastically installed at the rear end of the positioning seat 4. A guide wheel 15 is connected to the rear end of the carrier plate 10. The carrier plate 10 functions to drive the pushing frame 9 and the positioning column 16 to move. A connecting and fixing frame 27 is fixedly installed on the side surface of the lifting seat 7. The end of the connecting and fixing frame 27 is fixedly installed with the pushing frame 9. The connecting and fixing frame 27 functions to fix the pushing frame 9. The lower end of the pushing frame 9 is inclined, which can push the guide wheel 15, thereby driving the carrier plate 10 to move. The guide wheel 15 is attached to the lower end of the pushing frame 9. Two pressing frames 21 are fixedly installed at the upper end of the carrier plate 10. The pressing frames 21 can press on the upper end of the brake handle 34 to fix it in the positioning groove 19. The end of the carrier plate 10 is connected with a positioning column 16. The positioning column 16 can be inserted into the hole at the end of the brake handle 34. At this time, the positioning column 16 is in contact with the hole wall of the brake handle 34 to fix the brake handle 34 so that it cannot be displaced.

[0029] A guide sleeve 20 is fixedly installed at the upper edge of the positioning seat 4. The pressing frame 21 slides through the inside of the guide sleeve 20. The guide sleeve 20 functions to guide the pressing frame 21. A column seat 17 is inlaid on the outer surface of the positioning column 16. The end of the column seat 17 is fixed to the carrier plate 10. The column seat 17 functions to fix the positioning column 16. The edge of the end of the positioning column 16 is beveled, which is convenient for the positioning column 16 to be inserted into the hole at the end of the brake handle 34. The upper and lower edges of the end of the pressing frame 21 are arc-shaped, which is convenient for the pressing frame 21 to move onto the brake handle 34 to tightly press and fix the brake handle 34 in the positioning groove 19. Wheel seats 14 are installed at both ends of the guide wheel 15. The ends of the wheel seats 14 are fixed to the carrier plate 10. The wheel seats 14 function to support the guide wheel 15.

[0030] Two bearing holes 18 are symmetrically opened at the rear end of the positioning seat 4. A guiding column 11 is coaxially embedded at the front end inside the bearing hole 18. The bearing hole 18 serves to accommodate the guiding column 11 and the return spring 12. The guiding column 11 extends out from the inside of the bearing hole 18. The carrier plate 10 is slidably mounted on the outer surface of the guiding column 11. The guiding column 11 serves to guide the carrier plate 10. A limit cap 13 is coaxially embedded at the end of the guiding column 11. The limit cap 13 abuts against the rear end of the carrier plate 10. The limit cap 13 serves to prevent the carrier plate 10 from separating from the guiding column 11. A return spring 12 is wound around the outer side of the guiding column 11. One end of the return spring 12 is fixed to the front end of the carrier plate 10. The return spring 12 can push the carrier plate 10 to reset the moved carrier plate 10. The other end of the return spring 12 is fixed to the front end inside the bearing hole 18.

[0031] Two extension frames 32 symmetrically and obliquely extend downward from the lower end of the drilling table 2. A frame seat 33 is fixedly installed at the end of the extension frame 32. The extension frame 32 serves to extend the drilling table 2. The end of the frame seat 33 is fixed to the machine frame 1. The lower end of the positioning seat 4 extends with a support frame 3. The frame seat 33 serves to carry the extension frame 32. The end of the support frame 3 is fixed to the drilling table 2. The support frame 3 serves to support and fix the positioning seat 4.

[0032] During drilling, by using the inclined positioning seat 4, the brake handle 34 can be first placed on the positioning seat 4. At this time, the brake handle 34 fits into the positioning groove 19 on the positioning seat 4 to position the brake handle 34, so that the drilling end of the brake handle 34 can be horizontally attached to the drilling support seat 5. At the same time, the stepped portion of the drilling support seat 5 abuts against the corner of the brake handle 34 to position it, so that the drilling end of the brake handle 34 is positioned below the drill bit 29. Subsequently, the first servo motor 8 operates to drive the threaded rod 28 to rotate, causing the lifting seat 7 screwed on the threaded rod 28 to move downward. At this time, the guide seat 26 slides on the guide rail 25 to guide the downward-moving lifting seat 7, and the drill bit 29 and the pushing frame 9 are respectively driven to move downward through the downward-moving lifting seat 7. When the pushing frame 9 moves downward, the guide wheel 15 rolls along the inclined section of the pushing frame 9 to push the carrier plate 10, so that the carrier plate 10 can slide on the guide post 11, thereby driving the pressing frame 21 to move, so that the pressing frame 21 can press on the upper end of the brake handle 34 to fix it in the positioning groove 19. Subsequently, the pushing frame 9 continues to move downward, causing the carrier plate 10 to continue to move, so that the positioning post 16 fits into the hole at the end of the brake handle 34, and the brake handle 34 is firmly fixed through the pressing frame 21 and the positioning post 16. At this time, the guide wheel 15 just rolls to the vertical section of the pushing frame 9, so that when the lifting seat 7 continues to move downward subsequently, the guide wheel 15 can roll at the vertical part of the pushing frame 9, keeping the pressing frame 21 and the positioning post 16 stationary. When the brake handle 34 is fixed, the drill bit 29 just moves downward close to the upper side of the brake handle 34. Subsequently, the second servo motor 24 operates to drive the drill bit 29 on the drive shaft 30 to rotate through the synchronous belt 23. Subsequently, the lifting seat 7 continues to drive the drill bit 29 to move downward to perform drilling on the brake handle 34.
