AI Technical Summary
When drilling holes of existing multi-axis independent feed CNC drilling machine tools, cutting fluid cannot accurately cover the drill bit position, resulting in problems such as wear and reduction in drill bit accuracy.
A cleaning component is designed, including a circular rod and a circular tube. When the drill bit is rotated by an independent feed shaft seat, the cutting fluid accurately erodes the drill bit working area through the circular tube, and adjusts the water flow angle with the ball hinge shaft to ensure the cleaning effect.
It effectively avoids the reduction in drill bit accuracy, improves the accuracy of cleaning and the convenience of the device, and meets the requirements of different operating environments.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of numerical control machine tool equipment, in particular to a numerical control drilling and tapping machine for metal processing with multi-axis independent feeding. Background Technique
[0002] The multi-axis independent feeding numerical control drilling and tapping machine is an advanced metal processing equipment. This kind of machine tool has multiple axes. "Independent feeding" means that each axis can work independently and precisely according to programming and control instructions without interference.
[0003] In the existing machine tool equipment, when machining parts, cutting fluid is needed to clean the drilling position. Usually, the cutting fluid is sprayed out through a pipe fitting at a fixed position. In this way, when the drill bit drills from one place to another, the cutting fluid in the pipe fitting may not accurately cover the position of the hole drilled by the drill bit. In this way, the iron filings in the hole currently drilled by the drill bit are likely to accumulate on the surface of the workpiece. If not cleaned in time, it will wear the drill bit, thus affecting the accuracy of the drill bit. Content of the Utility Model

[0006] The machine tool housing provides stable support for the operation of the device. Place the workpiece on the operating table. The telescopic rod expands and contracts to drive the shaft seat to slide to an appropriate position through the movable plate. At this time, the driving device operates. The driving component is a motor, and the drill bit rotates through the independent feed shaft seat to process the object. At this time, connect the water inlet pipe to the external pump body. The pump body pumps the cutting fluid into the water inlet pipe. As the drill bit moves, the circular pipe moves upward, and the sealing plug at the bottom of the circular rod separates from the water inlet pipe. The cutting fluid enters the interior of the circular pipe through the water inlet pipe and flows out from the water outlet pipe to wash the workpiece area where the drill bit works, avoiding the accumulation of iron chips in the hole on the surface of the workpiece and wearing the drill bit, resulting in a reduction in the accuracy of the drill bit. Compared with the existing device for spraying cutting fluid, the cleaning component can accurately clean according to the position of the drill hole of the drill bit, effectively avoiding the problem of low cleaning effect caused by range cleaning and easy residue of iron chips in the drill hole.

A plurality of through holes are formed in the outer wall of the ball hinge shaft, and a high-pressure nozzle is communicated with the outer wall of the second water outlet pipe:
[0008] When the water flow in the first water outlet pipe enters the second water outlet pipe through the through holes in the ball hinge shaft, due to the characteristic that the ball hinge shaft can rotate at any angle, the angle can be adjusted arbitrarily, enabling the operator to change the water flow angle according to the on-site operation environment, thus meeting different usage requirements and greatly improving the convenience of the device during use.
[0009] As a preferred technical solution of the present utility model, a collection box is fixedly connected to the outer wall of one of the support plates.

The outer wall of the circular tube 906 is communicated with a water inlet pipe 904 and a first water outlet pipe 907. The inner wall of the first water outlet pipe 907 is provided with an adjusting component 10.
[0022] The machine tool housing 1 provides stable support for the operation of the device. Place the workpiece on the operating table. The telescopic rod 4 expands and contracts to drive the shaft seat to slide to an appropriate position in cooperation with the movable plate 5. The driving device 6 operates, and drives the drill bit 8 to rotate through the independent feeding shaft seat 7 to process the object. At this time, connect the water inlet pipe 904 to an external pump body. The pump body pumps the cutting fluid into the water inlet pipe 904.

At this time, connect the inlet pipe 904 to an external pump body, and the pump body pumps the cutting fluid into the inlet pipe 904. As the drill bit 8 moves, the circular pipe 906 moves upward, and the sealing plug 908 at the bottom of the circular rod 901 disengages from the inlet pipe 904. The cutting fluid enters the interior of the circular pipe 906 through the inlet pipe 904 and flows out through the first outlet pipe 907 to wash the workpiece area where the drill bit 8 is working, preventing iron filings in the hole from accumulating on the workpiece surface and wearing the drill bit 8, resulting in a reduction in the accuracy of the drill bit 8. When the water flow in the first outlet pipe 907 enters the second outlet pipe 1003 through the through hole 1002 in the ball hinge shaft 1001, due to the characteristic that the ball hinge shaft 1001 can rotate at any angle, the angle can be adjusted arbitrarily, enabling the operator to change the water flow angle according to the on-site operation environment, thus meeting different usage requirements and greatly improving the convenience of the device during use.
