Description

Technical Field

[0001] The invention relates to the field of drilling facilities, in particular to a drilling machine for machining a brake handle which is easy to position. Background Art

[0002] Brake handles are usually an operating device installed on bicycles, electric vehicles, motorcycles and other vehicles to control the brake system to achieve the function of deceleration or stopping. When the brake handle is tightened, the force is transmitted to the brake device through the brake line, so that the brake pads or brake shoes contact the wheels or brake discs, thereby generating friction to slow down or stop the movement of the vehicle. Some of these modified brake handles are widely used because of their beautiful appearance.

[0003] When processing a modified brake handle, a drilling device is often used to drill a hole in the brake handle for easy assembly so that the hole can be used for subsequent assembly. However, due to the special shape of the brake handle, it is not convenient to use traditional positioning devices to position it during processing, which makes it inconvenient to drill holes in the brake handle.

The drilling end is positioned below the drill bit 29, and a positioning seat 4 is installed on the upper end of the drilling table 2 near the side of the drilling support 5. The positioning seat 4 is inclined to adapt to the inclination of the brake handle 34 itself, so that the brake handle 34 fits in the positioning groove 19 on the positioning seat 4, and the end of the brake handle 34 to be drilled can be horizontally fitted on the drilling support 5 to ensure that the hole wall drilled subsequently can be in a vertical state. A positioning groove 19 is opened in the middle of the upper end of the positioning seat 4, and a fixing handle is provided at the rear end of the positioning seat 4, and a drilling part is installed on the upper front end of the frame 1.

[0019] The drilling member includes a lifting seat 7 installed at the upper front end of the frame 1. The lifting seat 7 drives 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 driving shaft 30 is rotatably installed inside the carrier 6. The carrier 6 supports the driving shaft 30. The drill bit 29 is coaxially installed at the lower end of the driving shaft 30. The driving shaft 30 drives the drill bit 29 to rotate. The drill bit 29 corresponds to the top of the drilling support 5.

[0020] A No. 2 servo motor 24 is fixedly installed on the upper end of the carrier 6. The No. 2 servo motor 24 drives the driving shaft 30 to rotate. The output end of the No. 2 servo motor 24 and the outer surface of the driving shaft 30 are coaxially inlaid with a pulley 22. A synchronous belt 23 is connected between the two pulleys 22. The pulley 22 connects the synchronous belt 23, and the synchronous belt 23 transmits the 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 front end of the frame 1. The guide seat 26 and the guide rail 25 guide the lifting seat 7. The guide seat 26 is slidably installed on the guide rail 25.

[0021] A threaded rod 28 is provided between the two guide rails 25. The threaded rod 28 plays the role of driving the lifting seat 7 to move up and down.

[0023] A guide sleeve 20 is fixedly installed at the upper edge of the positioning seat 4, and a pressure frame 21 slides through the inside of the guide sleeve 20. The guide sleeve 20 guides the pressure frame 21. The outer surface of the positioning column 16 is inlaid with a column seat 17. The end of the column seat 17 is fixed to the carrier plate 10. The column seat 17 fixes the positioning column 16. The end edge of the positioning column 16 is set in a beveled shape, which can facilitate 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 pressure frame 21 are set in an arc shape, which can facilitate the pressure frame 21 to move to the brake handle 34 to 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 end of the wheel seat 14 is fixed to the carrier plate 10, and the wheel seat 14 supports the guide wheel 15.

[0024] Two bearing holes 18 are symmetrically provided at the rear end of the positioning seat 4. A guide column 11 is coaxially embedded in the front end of the inner part of the bearing hole 18.

One end of the reset spring 12 is fixed to the front end of the carrier 10. The reset spring 12 can push the carrier 10 to reset the moved carrier 10. The other end of the reset spring 12 is fixed to the front end of the inner part of the bearing hole 18.

[0025] Two extension frames 32 are symmetrically and obliquely extended 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 frame 1. A support frame 3 is extended from the lower end of the positioning seat 4. The frame seat 33 serves to support 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.

[0026] When drilling, the brake handle 34 can be placed on the positioning seat 4 by using the inclined positioning seat 4. At this time, the brake handle 34 fits in the positioning groove 19 on the positioning seat 4 to position the brake handle 34 so that the end of the brake handle 34 to be drilled can fit on the drilling support seat 5 in a horizontal state. At the same time, the stepped portion of the drilling support seat 5 is 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. Subsequently, the No. 1 servo motor 8 drives the threaded rod 28 to rotate, so that the lifting seat 7 screwed on the threaded rod 28 moves downward. At this time, the guide seat 26 slides on the guide rail 25 to guide the lifting seat 7 that moves downward, so that the drill bit 29 and the push frame 9 are driven downward by the lifting seat 7 that moves downward. When the push frame 9 moves downward, the guide wheel 15 rolls along the inclined section of the push frame 9 to push the carrier plate 10, so that the carrier plate 1 0 can slide on the guide column 11, thereby driving the pressing frame 21 to move, so that the pressing frame 21 can be pressed on the upper end of the brake handle 34 to fix it in the positioning groove 19, and then the push frame 9 continues to move downward, allowing the carrier plate 10 to continue to move, so as to drive the positioning column 16 to fit and insert into the hole at the end of the brake handle 34, so as to firmly fix the brake handle 34 through the pressing frame 21 and the positioning column 16. At this time, the guide wheel 15 just rolls to the vertical section of the push frame 9, so that when the subsequent lifting seat 7 continues to move downward, the guide wheel 15 can roll at the vertical part of the push frame 9, so that the pressing frame 21 and the positioning column 16 remain stationary. When the brake handle 34 is fixed, the drill bit 29 just moves down and approaches the top of the brake handle 34. Then the No. 2 servo motor 24 works to drive the drill bit 29 on the drive shaft 30 to rotate through the synchronous belt 23, and then the lifting seat 7 continues to drive the drill bit 29 to move downward to drill the brake handle 34.
