Detailed Implementation

[0019] The present invention will be further described below with reference to the embodiments.

[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0021] Please see Figure 1-4 This utility model provides a processing device for micro-hole molds for micro-irregular contact points, combined with Figures 1 to 4 As shown, the device includes a base 1, a support frame 2, a hydraulic drive system, a rotary drive system, a cleaning mechanism 8, and a worktable and positioning structure. The specific structure and operating principle of each component will be described in detail below with reference to the accompanying drawings.

[0022] The base 1 serves as the basic support for the entire device, with a support frame 2 welded to its top to ensure the overall stability and robustness of the device. Two hydraulic cylinders 3 are fixedly connected to the top of the support frame 2. The output end of the hydraulic cylinders 3 extends into the support frame 2 and is fixedly connected to the lifting plate 4. The hydraulic cylinders 3 drive the lifting plate 4 to move up and down through pressurized oil. The range of movement of the lifting plate 4 is determined by the stroke of the hydraulic cylinders 3, thereby precisely controlling the lifting and lowering movement of the drill bit 7 to adjust the drilling depth. A servo motor 5 is fixedly installed on the top of the lifting plate 4. The output end of the servo motor 5 is fixedly connected to the rotating shaft 6 through a coupling. The drill bit 7 is fixedly connected to the inner wall of the rotating shaft 6. The drill bit 7 has a conical shape and irregular texture 15 engraved on its outer wall. This design can significantly improve drilling efficiency and accuracy, and is especially suitable for the processing of micro-hole molds with micro-irregular contacts. After the servo motor 5 is started, it transmits the rotational power to the drill bit 7 through the rotating shaft 6. The drill bit 7 completes the drilling operation on the mold under high-speed rotation.

[0023] To extend the service life of drill bit 7 and ensure drilling accuracy, this utility model also includes a cleaning mechanism 8. The cleaning mechanism 8 comprises a liquid storage tank 9, a pump body 10, a liquid guide pipe 11, a spiral hose 12, and a spray pipe 13. The liquid storage tank 9 is welded to the top of the support frame 2, located between two hydraulic cylinders 3. A liquid filling hole is provided on the inner side of the top of the liquid storage tank 9, and a sealing plug is inserted into the filling hole to facilitate the replenishment of cleaning fluid. The pump body 10 is fixedly installed on the top of the liquid storage tank 9 to pump the cleaning fluid to the liquid guide pipe 11. A spiral hose 12 is fixedly connected to the bottom outer wall of the liquid guide pipe 11. The spiral hose 12 passes through the support frame 2 and the lifting plate 4, conveying the cleaning fluid to the spray pipe 13. 3 is located on the outside of the drill bit 7 and is ring-shaped. It has a diversion groove and multiple spray holes 14 inside. The diversion groove is connected to the spray holes 14 to ensure that the cleaning fluid can evenly cover the surface of the drill bit 7. After the drill bit 7 completes a drilling, the pump body 10 delivers the cleaning fluid in the storage tank 9 to the spiral hose 12 through the liquid guide pipe 11. The cleaning fluid then enters the diversion groove inside the spray pipe 13 through the spiral hose 12 and is evenly sprayed onto the surface of the drill bit 7 through the spray holes 14. The cleaning fluid serves two purposes: firstly, to remove the debris adhering to the surface of the drill bit 7, and secondly, to displace the heat generated by the drill bit 7 during high-speed drilling through liquid cooling, preventing the drill bit 7 from degrading or being damaged due to high temperature.

[0024] This utility model also includes a workbench and a positioning structure for supporting the mold to be processed and collecting waste chips. The workbench 17 is set on top of the pad 16, which is fixedly connected to the top of the base 1 near the support frame 2. A positioning block 18 is fixedly connected to the top of the pad 16, and the positioning block 18 matches the positioning groove at the bottom of the workbench 17 to ensure the accurate position of the workbench 17. A chip removal groove 20 is provided on the top outer wall of the workbench 17 to collect the waste chips generated after drilling. In addition, handles 19 are fixedly connected to both the front and rear sides of the workbench 17. The handles 19 are rectangular in shape to facilitate the operator to move the workbench 17. In actual operation, the mold to be processed is placed on the workbench 17. The positioning block 18 and the positioning groove cooperate to ensure the accurate position of the mold. After drilling is completed, the waste chips will fall into the chip removal groove 20 on the top of the workbench 17. The operator can move the workbench 17 through the handles 19 to clean the waste chips out of the chip removal groove 20. The design of the chip removal groove 20 makes the waste chips collected in a concentrated manner, avoiding the waste chips from scattering and affecting subsequent processing.

[0025] The operation process of this utility model is as follows: The mold to be processed is placed on the workbench 17, and the mold position is adjusted by the cooperation of the positioning block 18 and the positioning groove to ensure the accurate positioning of the mold; the hydraulic cylinder 3 is started, and the hydraulic cylinder 3 drives the lifting plate 4 to move downward through the pressure oil, so that the drill bit 7 approaches the surface of the mold; the servo motor 5 is started, and the servo motor 5 drives the drill bit 7 to rotate at high speed through the rotating shaft 6 to complete the drilling operation on the mold; after drilling is completed, the hydraulic cylinder 3 drives the lifting plate 4 to move upward, so that the drill bit 7 is removed from the surface of the mold; the pump body 10 is started, and the pump body 10 delivers the cleaning fluid in the storage tank 9 to the spiral hose 12 through the liquid guide pipe 11. The cleaning fluid then enters the diversion groove inside the spray pipe 13 through the spiral hose 12, and is evenly sprayed onto the surface of the drill bit 7 through the spray hole 14 to remove the debris adhering to the surface of the drill bit 7 and cool it down; the operator moves the workbench 17 by the handle 19 to clean the waste chips from the chip discharge groove 20, preparing for the next processing.

[0026] This utility model achieves multiple functions such as drill bit cleaning and cooling, convenient chip removal, and high-precision machining through optimized structural design. The cleaning mechanism 8 uses cleaning fluid to clean and cool the surface of the drill bit 7, removes the chips adhering to the surface of the drill bit 7, and replaces the heat generated by the drill bit 7 during high-speed drilling, thus extending the service life of the drill bit 7. The worktable and positioning structure achieve convenient chip removal through the chip removal groove 20 and the handle 19, avoiding the accumulation of chips that affect subsequent processing. The conical design of the drill bit 7 and the irregular texture 15 on the outer wall work together to significantly improve drilling efficiency and accuracy, and are especially suitable for the processing of micro-hole molds with micro-irregular contacts.

[0027] In summary, this utility model possesses significant technical advantages and application value in practical applications. Through the specific embodiments described above, operators can efficiently complete the micro-hole mold processing task for micro-shaped contacts, while ensuring the stability of the equipment and processing accuracy.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
