Description

Technical Field

[0001] The invention relates to the technical field of drilling machines, in particular to an automatic drilling machine. Background Art

[0002] A drilling machine is a machine tool that mainly uses a drill to make holes on a workpiece. Usually, the rotation of the drill is the main motion, and the axial movement of the drill is the feed motion. The drilling machine has a simple structure and relatively low processing accuracy. It can drill through holes and blind holes. By replacing special tools, it can expand, countersink, ream holes or perform tapping and other processing. During the processing, the workpiece does not move, and the tool moves to align the center of the tool with the center of the hole, and the tool rotates (main motion).

[0003] There are several disadvantages in the existing drilling machines: 1. The workpieces in the existing drilling machines are mostly fixed and cannot be processed continuously, especially when processing annular workpieces. The existing drilling machines are cumbersome to operate, inefficient and of poor practicality; 2. Most of the existing drilling machines are not equipped with debris collection devices, and the debris generated during drilling will accumulate on the workbench, affecting the cleanliness of the workbench and even causing a decrease in the processing accuracy of the workpiece. Summary of the invention

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. An automatic drilling machine of the present invention realizes the rotation of the workpiece by setting a driving mechanism and a fixing mechanism in cooperation with long rollers and short rollers, so that the drilling head can continuously process the annular workpiece, thereby improving the processing efficiency of the workpiece. When in use, the inner ring of the workpiece is first placed on the two driven pressure rollers, and then the electric push rod is started through the touch screen. The output end of the electric push rod is extended and drives the mounting block to move backward. The mounting block drives the two limit shafts to move backward. The two limit shafts drive the two driven pressure wheels to squeeze the inner ring of the workpiece, and make the workpiece and the active pressure wheel in close contact. Then the servo motor is started. The output end of the servo motor drives the active pressure wheel to rotate through the speed reducer and the direction change. The workpiece is driven to rotate through the active pressure wheel. The friction between the workpiece and the worktable is reduced by setting long rollers and short rollers, so as to improve the stability of the workpiece rotation and improve the processing accuracy of the workpiece.

[0014] 2. An automatic drilling machine of the present invention allows the debris on the workbench to fall directly into the slag receiving bucket by arranging a long installation groove, a short installation groove and a slide groove, thereby preventing the debris from affecting the rotation of the long rollers, etc., and then arranging a slag changing box to collect the residual debris on the upper end surface of the workbench, so as to keep the workbench clean.

[0025] like Figure 1-6 As shown, an automatic drilling machine comprises a main frame 1, a workbench 2 is installed on the upper end of the main frame 1, sealing plates 3 are installed at the front and rear ends of the main frame 1, two groups of symmetrical heat dissipation holes 7 are opened at the front end of the sealing plate 3, an electric box 15 is installed inside the main frame 1, a sub-frame 4 is installed at the lower left end of the main frame 1, a slag changing box 5 is installed at the upper end of the sub-frame 4, a door body 6 is installed at the front end of the slag changing box 5, the upper end surface of the slag changing box 5 is higher than the upper end surface of the workbench 2, and a workpiece 8 is placed in the middle of the upper end of the workbench 2. A fixing mechanism 9 and a driving mechanism 10 are arranged on the upper end of the workbench 2 from front to back. The fixing mechanism 9 is located inside the workpiece 8, and the driving mechanism 10 is located behind the workpiece 8. A column 11 is fixedly installed on the upper end of the workbench 2, and the column 11 is located directly behind the driving mechanism 10.

The operating box 13 is electrically connected to the drilling head 12, the driving mechanism 10, and the fixing mechanism 9.

[0026] Two front-to-rear symmetrical slide rails 21 are installed at the lower end of the workbench 2. The two slide rails 21 are slidably connected with a slag receiving bucket 22. The slag receiving bucket 22 is located directly below the fixing mechanism 9 and the driving mechanism 10. The setting of the slide rails 21 facilitates the extraction of the slag receiving bucket 22 to clean the broken slag inside it.

[0027] Two left-right symmetrical slide grooves 35 are opened at the upper end of the workbench 2, two long mounting grooves 31 are opened at the front part of the upper end of the workbench 2, and long rollers 33 are movably connected in the two long mounting grooves 31, and two short mounting grooves 32 are opened at the rear part of the upper end of the workbench 2, and short rollers 34 are movably connected in the two short mounting grooves 32.

When in use, the inner ring of the workpiece 8 is first placed on the two driven pressure wheels 44, and then the electric push rod 41 is started through the touch screen 14. The output end of the electric push rod 41 extends and drives the mounting block 42 to move backward. The mounting block 42 drives the two limit shafts 43 to move backward. The two limit shafts 43 drive the two driven pressure wheels 44 to squeeze the inner ring of the workpiece 8, and make the workpiece 8 in close contact with the active pressure wheel 53, and then the servo motor is started. The output end of the servo motor 51 is decelerated and changed direction by the reducer 52 to drive the active pressure wheel 53 to rotate, and the workpiece 8 is driven to rotate by the active pressure wheel 53. The long rollers 33 and the short rollers 34 are arranged to reduce the friction between the workpiece 8 and the workbench 2, improve the stability of the rotation of the workpiece 8, and help improve the processing accuracy of the workpiece. Finally, the drilling and cutting of the workpiece 8 are completed by the drilling head 12.
