Description

Technical Field

[0001] This utility model relates to the field of drilling technology for metal castings, and in particular to a drilling device for metal castings. Background Technology

[0002] Metal castings are metal products formed by pouring molten metal into a mold and allowing it to cool and solidify through a casting process. They are widely used in machinery, automobiles, and other fields. Since castings often need to be connected or assembled with other components after forming, bolt holes, pin holes, and other similar holes must be machined. Drilling equipment can precisely and efficiently complete the machining of these holes, meeting dimensional accuracy and positional requirements, and is a key piece of equipment for subsequent processing of castings.

[0003] When drilling most metal castings, the metal casting is usually placed on a machining platform and then fixed. After fixing, the drill bit is used to drill the metal casting. When drilling the metal casting, the machining platform will be subjected to force due to the cutting reaction force between the drill bit and the casting. This force will cause the platform to vibrate and shift, which will affect the drilling work, as well as equipment wear, noise, reduced tool life and production efficiency.

[0004] Therefore, it is necessary to provide a new drilling device for metal castings to solve the above-mentioned technical problems. Utility Model Content

A handle is fixedly connected to the distant side of the two rotating disks 18 away from the axis.

The elastic components are installed inside both the left and right sides of the support platform 1. Each elastic component includes a receiving chamber 22, with two receiving chambers 22 respectively located inside the left and right sides of the support platform 1.

The outer top end of a connecting rod 20 is rotatably connected to the inner wall of the bottom end of a sliding rod 13.

[0022] The working principle of the metal casting drilling device provided by this utility model is as follows: Before starting the operation, use the casters at the bottom of the support platform 1 to move the entire metal casting drilling device to a suitable working position. Then, place the metal casting to be processed on the processing platform 14, rotate the rotating disk 18 to drive the clamping threaded rod 16 to rotate, causing the clamping plate 17 to slide on the processing platform 14 until the metal casting is firmly clamped. Then, start the drive motor 12, which drives the drive threaded rod 10 to rotate. Since the threaded block 11 is threadedly connected to the drive threaded rod 10, and the L-shaped assembly plate 7 is slidably connected to the receiving long block 5, when the drive threaded rod 10 rotates, the threaded block 11 will drive the L-shaped assembly plate 7 to slide on the receiving long block 5, thereby adjusting the horizontal position of the servo motor 8 and the drill bit 9 so that they are aligned with the part of the metal casting to be drilled. At this time, start the electric push rod 4, and the drive end of the electric push rod 4 extends, driving the receiving long block 5 to slide. As block 5 moves down, the sliding plates 6 at both ends of the long block 5 slide synchronously along the support column 2, allowing the drill bit 9 to approach the metal casting and prepare for drilling. Then, the servo motor 8 is started, driving the drill bit 9 to rotate at high speed. At this time, the electric push rod 4 continues to control the long block 5 to move down, so that the rotating drill bit 9 gradually cuts into the metal casting for drilling. During the drilling process, the cutting reaction force between the drill bit and the casting will cause the processing platform 14 to vibrate and displace. The damper 19 at the bottom of the processing platform 14 will absorb some of the vibration energy. At the same time, the processing platform 14 transmits force to the connecting rod 20 through the sliding rod 13. The connecting rod 20 drives the connecting block 21 to slide on the fixed rod 23 in the receiving chamber 22, squeezing or stretching the spring 24. The elasticity of the spring 24 will buffer this vibration and displacement tendency, reducing the vibration and displacement of the processing platform 14.
