Technical Field

[0001] This utility model relates to the technical field of metal drilling equipment, specifically to a metal drilling equipment with drill bit adjustment function. Background Technology

[0002] Metal drilling equipment is a specialized machine used to process precise holes in metal materials. It is widely used in machinery manufacturing, automotive industry, aerospace, construction and other fields.

[0003] In the process of drilling metal, different drill bits are often required to be changed according to different needs. If there are multiple drilling requirements for the same part, it is often necessary to drill the same part multiple times. After each size of drilling is completed, the drill bit needs to be changed to drill the next size. This is relatively convenient for mass production, but it is not convenient for drilling some small batches or customized parts. Moreover, for some parts with larger holes, it is often necessary to change the drill bit repeatedly from small to large, which makes the drilling process more complicated. Utility Model Content

The outer side of the rotating shaft structure is provided with a connecting block that connects to the drilling motor structure. The outer side of one of the support ring plates is provided with a servo motor that drives the rotating shaft structure to rotate.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] Combined with appendix Figure 1-4 A metal drilling device with drill bit adjustment function includes a support base 1 and multiple drilling motor structures 10. The power end of each drilling motor structure 10 is equipped with a drill bit connection end 12, which is a common machine tool drill chuck. This chuck can clamp and disassemble drill bits of a certain size range. The specific size can be customized to meet different requirements. This is common existing technology and will not be elaborated further. The top of the support base 1 is equipped with a drilling device drive box 2. The top of the drilling device drive box 2 is equipped with an electric cylinder 4. The bottom power end of the electric cylinder 4 extends into the drilling device drive box 2 and is equipped with a lifting plate 5. L-shaped support rods 6 are located on both sides of the bottom of the lifting plate 5, and support ring plates 7 are located on the inner sides of the L-shaped support rods 6. Figure 3 , 4 As shown, the L-shaped support rods 6 and the support ring plate 7 on both sides can form a clamping structure on both sides, which facilitates the rotation of the multiple drilling motor structures 10 and the drill bit connection end 12 inside.

[0021] The two side support ring plates 7 are rotatably equipped with a rotating shaft structure 8 in the middle. Multiple drilling motor structures 10 are evenly distributed in a ring and are limited to rotate inside the two side support ring plates 7. The outer side of the rotating shaft structure 8 is equipped with a connecting block 11 that connects to the drilling motor structure 10. The outer side of one side support ring plate 7 is equipped with a servo motor 9 that drives the rotating shaft structure 8 to rotate. The bottom of the drilling equipment drive box 2 is equipped with an opening 24 that matches the drill bit connection end 12. That is, the required batch of drill bits are first installed on multiple drill bit connection ends 12 respectively. The servo motor 9 drives the rotating shaft structure 8 to rotate. The connecting block 11 turns the drilling motor structure 10 and the drill bit connection end 12 corresponding to the required size of the drill bit to face downwards. Then, the electric cylinder 4 drives the two side support ring plates 7 and the inner structure to lift and lower, thereby completing the drilling operation of the required size of the drill bit, such as drilling multiple holes of different sizes on a single part, or larger holes. The drill bits are drilled sequentially from small to large. For larger holes, the drill bits are drilled sequentially from small to large to ensure the smoothness of drilling.

[0022] The outer bottom of the support ring plates 7 on both sides is provided with a first electric push rod 15. The power end of the first electric push rod 15 is provided with a micro-pressure sensing module 17 extending to the rear side of the lowest drilling motor structure 10. The outer bottom of the support ring plates 7 on both sides is symmetrically provided with a second electric push rod 16. The power end of the second electric push rod 16 is provided with a positioning block 18 extending to the front and rear sides of the lowest drilling motor structure 10. In order to ensure that the corresponding drill bit connection end 12 can be set directly downwards, the circuit control logic is as follows: when the drill bit needs to be replaced, the micro-pressure sensing module 17 and the positioning block 18 are first retrieved through the first electric push rod 15 and the second electric push rod 16. Then, the drill motor structure 10 that is not needed is rotated to a suitable angle (i.e., the drill motor structure preceding the corresponding drill motor structure 10 that is needed). After passing through the micro-pressure sensing module 17, the first electric push rod 15 drives the micro-pressure sensing module 17 to extend. Then, the required drilling motor structure 10 rotates to a suitable angle (i.e., after the drilling motor structure 10 touches the micro-pressure sensing module 17), and the positioning block 18 extends through the second electric push rod 16. By positioning and clamping the drilling motor structure 10 on both sides, it can be ensured that the drilling motor structure 10 is facing downwards, ensuring drilling accuracy. If the equipment production cost is sufficient, a corresponding PLC control panel can be set up. Each time a drill bit is installed, each drilling motor structure 10 is numbered. Then, the corresponding drill bit size is input into the corresponding numbered drilling motor structure 10 through the PLC control panel, which facilitates the operation and selection of the appropriate drill bit size. This is a common PLC circuit control module, so it will not be described in detail.

[0023] The support base 1 has a drilling structure 3 in the middle that matches the drill bit connection end 12. The bottom of the support base 1 has a discharge trough 25. The drilling equipment drive box 2 has a water spray structure 26 that is aligned with the drilling structure 3. The water spray structure 26 includes an external water inlet pipe, a water valve and a water spray head. This is a common water spray structure, so it will not be described in detail. The drilling structure 3 is set up mainly to prevent damage to the drill bit when drilling through, and at the same time, it is convenient to cool down in time in conjunction with the water spray structure 26.

[0024] The inner sides of the support ring plates 7 on both sides are provided with limiting ring grooves 13. The drilling motor structure 10 is provided with limiting sliding columns 14 on both sides to cooperate with the limiting ring grooves 13. The setting of limiting ring grooves 13 and limiting sliding columns 14 can ensure more stable operation of the drilling motor structure 10. The drilling motor structure 10 is generally set as an external fixed shell and an internal motor. The power end of the internal motor is connected to the drill bit connection end 12. The external shell is connected to the limiting structure. The external shell mainly serves to fix the motor. The lifting plate 5 is provided with auxiliary plates 19 on both sides. The top of the auxiliary plate 19 is provided with a first limiting rod 20 that penetrates the drilling equipment drive box 2. The top of the drilling equipment drive box 2 is provided with a limiting sleeve 21 that cooperates with the first limiting rod 20. The outer ends of the support ring plates 7 are provided with limiting plates 22. The inside of the drilling equipment drive box 2 is provided with a second limiting rod 23 that penetrates the limiting plate 22. At the same time, the multiple limiting rod structures can ensure the stable lifting operation of the drilling structure.

[0025] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
