Abstract

The invention relates to a manual multi-purpose drilling device which is characterized in that a handle and a drill pipe are connected, the drill pipe (2) is connected with a safety coupler through a flat key, the upper edge of an internal spiral rotating drum is connected with the safety coupler through a flange, and the inner spiral rotating drum is connected with an outer sleeve through threads. An annular retainer ring is arranged between the drill pipe and the internal spiral rotating drum, wherein a center hole of the annular retainer ring is sleeved on the drill pipe in a fixed-connection mode, the annular retainer ring makes contact with the lower edge of the internal spiral rotating drum in a sliding mode, and the drill pipe is connected with a drill bit chuck through threads. Two double-head screw rods (8) are arranged in sliding chutes in the two ends of a supporting plate (10) respectively, the lower ends of the double-head screw rods are connected with frame-shaped clamping plates (11) through threads, and bosses at the lower ends of the double-head screw rods are arranged in bowel-shaped sleeves. The supporting plate (10) and the outer sleeve (6) are arranged coaxially and movably connected through flat keys. By using of the device, in the whole process of manual drilling, only one action of rotating the drill pipe is needed to finish the manual drilling, through reference to scale marks on the drill pipe, the accurate drilling can be achieved, and replaceable clamping frames can be flexibly used in kinds of drilling places.

Description

technical field

[0001] The invention relates to a device capable of realizing manual drilling operation on the surface of metal and non-metal materials, which belongs to the field of mechanical manufacturing. Background technique

[0002] Most of the current drilling devices are powered by electricity, but in some workplaces that lack power supply, such as field construction operations, or places where electricity is prohibited, electric drilling devices cannot play their role, and drilling requires Do it by hand. At present, there are still few inventions of manual drilling devices in China, and there is a lack of devices that can realize convenient and accurate drilling on metal surfaces. In the utility model patent with the application number of 201120271695.9, although the invention device realizes the basic metal drilling operation, the drilling operation is too cumbersome, and the two positions need to be rotated continuously to realize the drilling. The degree needs...

Examples

Embodiment

[0035] Drill a piece of material into a No. 45 steel plate with a length of 1000 mm, a width of 250 mm, and a thickness of 10 mm. Before operation, first clamp the 8mm machine drill bit, and reset the scale mark 14 on the drill rod to zero, and then adjust the nut 9 so that when the drill bit is on the upper surface of the steel plate, the clamping frame 15 can just hold it from the side Steel plate, then the handle 1 is loaded onto the upper end of the double-ended screw rod 8, and the handle 1 is turned so that the movable splint 13 tightens the steel plate. Then the handle 1 is moved to the upper end of the drill rod 2, and the handle 1 is rotated to start the drilling operation until the end. The whole process takes about 5 minutes from preparation to completion. In order to drill other holes along the same line as the first hole on the board, just reverse the handle 1 to move the drill bit 8 out of the first hole, and then move the bracket 10 so that the double-ended scr...
