Description

Technical Field

[0001] This utility model belongs to the field of radial drilling technology, and in particular relates to a radial drilling machine. Background Technology

[0002] A radial drilling machine is a type of drilling machine in which the radial arm can rotate and move up and down around the column, and the spindle box usually moves horizontally on the radial arm. When machining holes on a vertical drilling machine, the alignment of the tool and the workpiece is achieved by moving the workpiece, which is obviously very inconvenient for some large and heavy workpieces. However, a radial drilling machine can use the position of the moving tool axis for alignment, which greatly facilitates the machining of holes on large and heavy workpieces in single-piece and small-batch production. It can also be called a radial drill, a hole machining equipment that can be used for drilling, reaming, tapping, and end face finishing. According to the machine tool clamping structure, radial drilling machines can be divided into hydraulic radial drilling machines and mechanical radial drilling machines. Among various types of drilling machines, radial drilling machines are convenient and flexible to operate, have a wide range of applications, and are typical. They are particularly suitable for machining holes in large parts with multiple holes in single-piece or batch production, and are common machine tools in general machining workshops. However, existing radial drilling machines usually have a worktable, and after drilling, drill chips are left on the worktable, which is inconvenient to clean. Utility Model Content

[0003] In view of the shortcomings of the prior art, this utility model provides a radial drilling machine, which solves the technical problem that existing radial drilling machines usually have a worktable, and after drilling, drill chips are left on the worktable, which is inconvenient to clean.

[0004] In view of the shortcomings of the prior art, this utility model provides a radial drilling machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0006] A radial drill includes a base on which a radial drill body is mounted. The base has a fixed plate on its upper surface, a worktable hinged to its upper end, a support plate fixed to its bottom surface, and the lower end of the support plate contacting the upper surface of the base. An angle adjustment device is provided between the worktable and the base to adjust the angle of the worktable. A fixed frame is fixed to the rear surface of the worktable. A rectangular groove is formed on the front of the fixed frame, a slide rod is fixed within the groove, and a slider slides along the slide rod. A first screw is fixed within the rectangular groove and threadedly connected to the slider. A second rotating shaft is rotatably mounted on the front of the slider, a rotating cylinder is fixed to its side surface, and a cleaning brush is mounted on the side surface of the rotating cylinder. The cleaning brush contacts the upper part of the worktable. An acceleration device is provided on the slider to rotate the cleaning brush.

[0007] Furthermore, the acceleration device includes a first large gear, which is rotatably connected to the front of the slider. A first rotating shaft is rotatably connected to the front of the slider. A first small gear and a second large gear are fixedly provided on the side surface of the first rotating shaft. The first small gear meshes with the first large gear. A second small gear is fixedly provided on the side surface of the second rotating shaft. The second small gear meshes with the second large gear. A rack is fixedly provided on the top surface of the rectangular groove. The rack meshes with the first large gear.

[0008] Furthermore, the angle adjustment device includes a guide rail, which is fixedly mounted on the upper surface of the base. A movable block is slidably mounted on the guide rail. A movable arm is hinged to the top surface of the movable block. The upper end of the movable arm is hinged to the bottom surface of the worktable. A second motor is fixedly mounted on the upper surface of the base. A second screw is fixedly mounted on the drive end of the second motor. The second screw is threadedly connected to the movable block.

[0009] Furthermore, a limiting plate is fixedly provided on the upper surface of the base, and the limiting plate is rotatably connected to one end of the second screw.

[0010] Furthermore, a first motor is fixedly mounted on one side surface of the fixing frame, and the driving end of the first motor is fixedly connected to one end of the first screw.

[0011] Furthermore, a waste box is placed below one end of the workbench.

[0012] Furthermore, the diameter of the first large gear is larger than the diameter of the first small gear, the diameter of the first small gear is smaller than the diameter of the second large gear, and the diameter of the second large gear is larger than the diameter of the second small gear.

[0013] The beneficial effects of this utility model are:

[0014] After drilling is complete, drill cuttings will remain on the worktable. Placing the waste bin below the right end of the worktable and adjusting the tilt angle of the movable arm will raise the left end of the worktable, thus tilting it. Moving the slider to the right will move the cleaning brush and the first large gear to the right. The rack meshes with the first large gear, causing it to rotate counter-clockwise as it moves to the right. This counter-clockwise rotation of the first large gear drives the first small gear to rotate clockwise. Since the diameter of the first large gear is larger than that of the first small gear, the rotational speed of the first small gear is greater than that of the first large gear. The clockwise rotation of the first pinion gear drives the clockwise rotation of the second large gear. The first pinion gear and the second large gear are fixed on the side surface of the first rotating shaft so that the rotation speed of the second large gear is the same as that of the first pinion gear. The clockwise rotation of the second large gear drives the second pinion gear to rotate counterclockwise. The diameter of the second large gear is larger than that of the second pinion gear, so that the rotation speed of the second pinion gear is greater than that of the second large gear. The counterclockwise rotation of the second pinion gear drives the cleaning brush to rotate counterclockwise. The cleaning brush moves to the right and rotates counterclockwise to clean the upper part of the worktable. Attached Figure Description
