If the debris generated by the chamfering process cannot be effectively cleaned, it will affect the processing of other holes on the surface of the plate and reduce the efficiency of the internal chamfering of the hole. Therefore, a four-axis CNC drill for internal chamfering is proposed. Utility Model Content

[0026] Furthermore, in order to facilitate chamfering of holes on the surface of the plate, avoid the accumulation of a large amount of debris that affects the processing efficiency, and improve the quality of the chamfering process, the chamfering mechanism includes a first adjusting motor 5, the first adjusting motor 5 is fixedly connected to the housing 1, the output end of the first adjusting motor 5 is fixedly connected to a screw 10, the surface of the screw 10 is threadedly connected to a base 7, the front of the base 7 is rotatably connected to an adjusting seat 9, the adjusting seat 9 is mounted with an active motor 8 through a bracket, and the interior of the adjusting seat 9 is rotatably connected to a chamfering head 11;

[0027] Furthermore, in order to facilitate the cooling of the chamfering head 11 during operation, and to facilitate its adjustment and the processing of holes on the surface of the plate, a second adjusting motor 22 is slidably connected to the rear of the shell 1, and the output end of the second adjusting motor 22 is fixedly connected to the adjusting seat 9. An adjusting cylinder 6 is provided above the adjusting seat 9. A liquid sprayer 14 is also provided inside the shell 1, and a feeding rack 12 is provided below the liquid sprayer 14. Two groups of sliding plates 21 are slidably connected to the front of the feeding rack 12, and a matching plate 13 is fixedly connected to one side of the sliding plate 21.

[0028] Furthermore, in order to facilitate the solid-liquid separation of the processed debris and the used coolant, and to improve the quality of the subsequent chamfering of the holes, the internal rotation of the feed rack 12 is connected to a rotating rod 15, and the surface of the rotating rod 15 is fixedly connected to a cam 16, and a sliding column 17 is provided below the cam 16, and a filter plate 18 is provided below the sliding column 17, and the filter plate 18 is rotatably connected to the shell 1 through a pin shaft.

[0029] Furthermore, in order to facilitate the filtering work of the filter plate 18, multiple sets of return springs are arranged between the filter plate 18 and the shell 1, extrusion springs are arranged between the sliding plate 21 and the feed rack 12, and multiple sets of pulleys are arranged inside the feed rack 12, and extrusion springs are also arranged between the pulleys and the feed rack 12.

[0030] Furthermore, in order to better handle the debris, a fixed rod 19 is fixedly connected to the surface of the sliding column 17, and the fixed rod 19 is slidably connected to the shell 1. A knocking ball 20 is fixedly connected above the fixed rod 19, and the knocking ball 20 is made of rubber material.

[0031] Furthermore, in order to facilitate the collection of waste liquid and debris, the waste liquid tank 3 is located directly below the filter plate 18, the collection box 4 is located at the discharge port directly in front of the filter plate 18, and the liquid sprayer 14 is an external liquid storage tank.

[0032] Furthermore, in order to facilitate cleaning of the processed plate, a cleaning cylinder 23 is rotatably connected to the opening at the rear of the shell 1, and a sponge is provided on the surface of the cleaning cylinder 23.

[0033] Furthermore, in order to more conveniently clean the debris into the collection box 4, a return spring is also provided between the filter plate 18 and the shell 1, the base 7 and the shell 1 are slidably connected, and the sprayer 14 and the feed rack 12 are detachably connected.

[0034] The working principle and use process of the present invention are as follows: after the present invention is installed, the plate to be processed is first inserted into the interior of the housing 1 through the two sets of matching plates 13, and then the first adjusting motor 5 is started to drive the screw 10 to rotate. The rotation of the screw 10 can drive the base 7 to rotate, and the position of the chamfering head 11 can be adjusted left and right. Then the second adjusting motor 22 is started to drive the adjusting seat 9 to rotate, and the angle of the chamfering head 11 for processing the holes on the surface of the plate is adjusted. After the adjustment is completed, the active motor 8 is started to rotate and drive the chamfering head 11 to rotate through the belt. At this time, the height of the chamfering head 11 is adjusted by starting the adjusting cylinder 6, and the holes on the surface of the plate can be chamfered.

[0035] When the chamfering head 11 has finished processing one of the holes on the surface of the plate, the chamfering head 11 is controlled to move upward by adjusting the cylinder 6, and the staff pushes the plate to move backward inside the shell 1, so as to facilitate processing of other holes on its surface. At this time, the backward movement of the plate will cause friction transmission to drive the rotating rod 15 to rotate, and the rotation of the rotating rod 15 can drive the cam 16 to rotate. The rotation of the cam 16 can intermittently push the slide post 17 up and down, and the up and down movement of the slide post 17 can drive the filter plate 18 to swing around the pin shaft. When the chamfering head 11 is processing the holes on the surface of the plate, the sprayer 14 will continuously spray coolant onto the surface of the chamfering head 11 to cool it down, and the debris left by the chamfering processing will flow to the surface of the filter plate 18 together with the waste liquid, and the waste liquid will directly fall into the interior of the waste liquid tank 3 through the filter plate 18 for collection, which is convenient for subsequent waste liquid treatment;

[0036] When the filter plate 18 swings around the pin, the swing of the filter plate 18 can drive the debris to shake, so that the debris falls into the collection box 4 through one end of the filter plate 18 for collection, which can effectively prevent the debris from accumulating on the surface of the plate in large quantities and affecting the efficiency of subsequent hole processing on the surface of the plate. At the same time, the up and down movement of the slide column 17 can drive the fixed rod 19 to move, and the fixed rod 19 can drive the knocking ball 20 above to knock on the bottom of the plate, so that the sprayed coolant and the debris are mixed and discharged downward by the flow of the coolant, which can further improve the effect of processing the debris on the surface of the plate.

[0037] When the holes on the plate surface are processed, the plate is pulled out from the rear of the housing 1. At this time, the upper and lower surfaces of the plate will come into contact with the cleaning cylinder 23, thereby wiping the processed plate surface to prevent coolant and debris from adhering to the plate surface and affecting the staff's observation.

[0038] Since the plate is inserted into the interior of the shell 1 through the matching plate 13, the matching plate 13 will be clamped by the extrusion force of the spring on one side of the sliding plate 21 under the action of the sliding plate 21, which can effectively improve the stability of the plate when the chamfering head 11 processes the plate, avoid the plate from shaking, and affect the quality of the hole processing on the surface of the plate. At the same time, when the plate contacts the multiple sets of pulleys inside the feed rack 12, since the surface of the pulley is also provided with a spring, it is convenient for the transportation of the plate and can also improve the stability of the plate during processing.

[0039] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
