[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] The utility model provides a drilling machine with automatic chip removal.

[0025] like Figure 1-3 As shown, it includes a workbench 1, a linear feed mechanism, and a coolant supply device. The linear feed mechanism is driven by a spindle linear feed cylinder, a spindle, a spindle stroke sensor block, and a tool. The cooling supply device is provided with a liquid supply box 2. An automatic chip removal device is provided at the lower side of the workbench 1. The automatic chip removal device includes a shell 3, a collecting trough 4, a conveying pipe 5, a screw propeller 6, a separation box 7, and a chip storage box 8. The shell 3 is fixed on the workbench 1. The collecting trough 4 is arranged directly below the workbench 1. The conveying pipe 5 is connected between the collecting trough 4 and the separation box 7. The screw propeller 6 is installed in the conveying pipe 5. The screw propeller 6 is connected to a propulsion motor. The separation box 7 includes a box body, a filtering mechanism 71 and a separation mechanism 72. The liquid supply box 2 is fixed in the shell 3.

[0026] The filtering mechanism 71 includes a driving roller 712 and a filter mesh conveyor belt 711. The filter mesh conveyor belt 711 is tilted and arranged directly below the outlet of the conveying pipe 5. The driving roller 712 is connected to a driving motor, which is installed on the box body. The chip storage box 8 is arranged at the rear end of the filter mesh conveyor belt 711.

[0027] The separation mechanism 72 includes a separation tank 721, a sedimentation weir plate 722, an electromagnet 723 and a liquid return pipe 724. The separation tank 721 is arranged directly below the filter mesh conveyor belt 711. The sedimentation weir plate 722 is installed in the middle of the separation tank 721 to separate the separation tank 721 into a sedimentation tank and a liquid storage tank. The cross-section of the sedimentation weir plate 722 is arranged in a corrugated shape. The electromagnet 723 is arranged on the outer wall of the separation tank 721 corresponding to the sedimentation tank directly below. The liquid return pipe 724 connects the liquid storage tank and the liquid supply tank 2. The liquid return pipe 724 is arranged in an arch shape. The highest point of the liquid return pipe 724 is higher than the upper side wall of the liquid supply tank 2. The liquid return pipe 724 is connected to a recovery pump. A recoil pipe 9 is arranged on the top of the sedimentation tank. The recoil pipe is connected to a recoil pump. The bottom of the side wall of the sedimentation tank A recoil slot 10 is provided, and a recoil gate 11 is slidably installed on the outer side of the recoil slot 10. An opening and closing cylinder 12 is connected to the sedimentation trough, and the cylinder arm of the opening and closing cylinder 12 is connected to the recoil gate 11. A locking switch is connected between the sedimentation trough and the recoil gate 11, and the locking switch includes a T-shaped locking block 13 and a locking spring 14. A sliding slot hole is provided on the side wall of the sedimentation trough, and the T-shaped locking block 13 includes an integrally formed locking rod and a suction block, and the locking rod is set to a non-magnetic material. The T-shaped locking block 13 is inverted and slidably connected in the sliding slot hole, and the locking spring 14 abuts between the sliding slot holes of the suction block, and the suction block and the electromagnet 723 magnetically repel each other. The recoil gate 11 is provided with a locking hole, and the locking rod is slidably inserted in the locking hole.

[0028] Working principle: The cuttings generated by the drilling machine in the utility model during the processing of iron workpieces enter the collection tank 4 under the impact of the coolant, and enter the conveying pipe 5 from the collection tank 4. Under the push of the spiral propeller 6 in the conveying pipe 5, the chips are pushed to the filter conveyor belt 711. The large particles of chips are initially filtered and separated from the coolant. The large particles of chips are transported to the chip storage box 8 through the filter conveyor belt 711. The dust-like chips and coolant that have been filtered are mixed and enter the sedimentation tank. The sedimentation tank and the liquid storage tank A corrugated sedimentation weir plate 722 is arranged in between, which increases the flow area, can reduce the flow speed of the coolant from the sedimentation tank into the liquid storage tank, and reduce turbulence. Under the damming effect of the sedimentation weir plate 722, the dusty chips will be deposited in the sedimentation tank and separated from the coolant. At the same time, the separation of the dusty chips and the coolant is further strengthened under the magnetic attraction of the electromagnet 723, and recovered to the liquid supply tank 2 through the return pipe 724, so that the separation of the coolant and the dusty chips is more thorough, so that the coolant can be effectively recycled.

[0029] In addition, when a certain amount of dust-like chips are deposited in the sedimentation trough, the height of the chip deposition surface will gradually increase, causing the deposition weir plate 722 to lose its function. Therefore, the sedimentation trough needs to be cleaned regularly. During this process, the electromagnet 723 is turned off, and the repulsive force between the electromagnet 723 and the suction block disappears. Under the action of the locking spring 14, the T-shaped locking block 13 slides downward to disengage from the recoil gate 11. The opening and closing cylinder 12 can pull the recoil gate 11, and the recoil slot 10 is opened. The recoil water flow is introduced through the recoil pipe 9 to impact the dust-like chips and discharge them from the recoil slot 10, thereby completing the cleaning of the sedimentation trough. After cleaning, the recoil gate is closed, the electromagnet 723 is opened, and the suction block resets the locking rod under the action of the repulsive force to lock the recoil gate, and the automatic chip removal device continues to operate.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
