Description

Drilling machine to make vertical hall}

The present invention relates to a drilling machine for vertical hole processing, and more particularly to a drilling machine for vertical hole processing to enable easy and accurate machining of the hole in the vertical direction of the workpiece.

In general, the drilling machine is one of the most widely used tools in a variety of machining and assembly fields are used to machine the hole in most workpieces.

Types of such drilling machines include table top drilling machines with machining centers for machining and portable drilling machines which allow the operator to carry out the drilling work easily.

In particular, the portable drilling machine is composed of a body formed with a handle that can be held by the operator and a drill installed on the body. Forced pressurization and rotation of the drill allow holes to be formed.

On the other hand, in the case of forming a vertical hole using a conventional drilling machine, since there is no separate device for maintaining the processing direction, position and depth in the exact vertical direction, the operator simply forms the vertical hole with working skill and attention. shall. However, no matter how highly skilled and careful during the operation, there is a problem that it is difficult to properly form a vertical hole having the correct vertical position and the set depth by the vibration of the operating drilling machine.

The present invention is to solve the above-mentioned problems, an object of the present invention is to maintain a precise machining direction and position in the vertical direction during vertical hole processing, and also to vertically adjust the depth of the hole to perform drilling To provide a drilling machine for processing.

And preferably characterized in that the locking step is formed on one end of the support rod.

Also preferably, the support rod is provided with a first support rod having the restoring spring installed therein and a second support rod having a stopper mounted on an outer circumference thereof so as to slide along the longitudinal direction to adjust the moving width of the moving bracket. It is characterized by.

Also preferably, the stopper is formed with a screw hole penetrating through the outside, the screw hole is characterized in that the fixing screw for fixing the position of the stopper is mounted.

Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the drawings.

Drilling machine for a vertical hole processing according to the present invention, as shown in Figure 1 body 110 is equipped with a handle 110 and the switch 111 and the mounting portion is mounted to the drill 130 on the upper side of the body 100 It consists of 120. This configuration is the same as a conventional portable drilling machine. On the other hand, the mounting portion 120 is equipped with a drill 130 for processing. The drill 130 can be installed in a variety of replacement, such as twist drill, center drill, boring drill, depending on the intended use.

In addition, the fixing bracket 200 having a circular ring shape is mounted to a portion adjacent to the mounting portion 120 of the body 100. The fixing bracket 200 is provided with a screw hole 210 formed to penetrate from the outside, the fixing screw 220 is coupled to the screw hole 210 is fixed to the body 100, the fixing bracket 200 is firmly mounted It is supposed to be.

In addition, the fixing bracket 200 is formed with two sliding holes 230 which are opened to both sides back and forth, and two support rods 240 and 250 are installed in the sliding holes 230, respectively. The supporting rods 240 and 250 are configured to slide in the sliding hole 230. In addition, a separate restoring spring 260 is installed on the outer circumference of the first support rod 240 among the support rods, and a stopper 270 is mounted on the outer circumference of the second support rod 250. A locking jaw 251 is formed at an end of the 250 that is exposed to the outside of the sliding hole 230.

The stopper 270 is slidable along the straight direction of the drill 130 on the second support rod 250, and a separate screw hole 271 is formed on the side. A fixing screw 272 is mounted to the screw hole 271 so that the stopper 2 O is press-fixed and fixed to the position desired by the user on the second support rod 250.

On the other hand, the movable bracket 280 is mounted on the outer ends of the first support rod 240 and the second support rod 250. The movable bracket 280 is similar in shape to the fixed bracket 200 described above, and only ends of the first and second support rods 240 and 250 are screwed to the movable bracket 280. It is fixedly mounted by a combination. Therefore, when each of the support rods 240 and 250 slides on the sliding holes 230 of the fixed bracket 200, the movable bracket 280 also slides together with these support rods 240 and 250.

The through-hole 281 is formed in the center of the movable bracket 280, the inner circumferential diameter of the through-hole 281 is formed significantly larger than the diameter of the drill 130, so that the drill 130 penetrates without any interference The drilling operation is made possible through the hole 281.

Hereinafter, the operation state of the vertical hole drilling machine according to the present invention configured as described above will be described with reference to FIGS.

For use of the drilling machine according to the invention the drilling machine is placed in the part for forming a vertical hole on the workpiece 300. At this time, the movable bracket 280 is in contact with the surface of the workpiece 300, the end of the drill 130 is in contact with the vertical hole forming portion.

In this state, when the operator presses the switch 111 to rotate the drill 130 and simultaneously pushes the body 100, the drill 130 has a vertical hole formed on the surface of the workpiece 280. At this time, by the moving bracket 280, the drill 130 is continuously maintained in a stable vertical state, and at the same time, while the drill 130 enters the workpiece 300 while processing the vertical hole, the moving bracket 280 supports the support rod. While moving with the 240 and 250, the contact state with the workpiece 300 is well maintained.

In this case, the movable bracket 280 and the support rods 240 and 250 are supported by the support rods 240 and 250 by sliding in the sliding hole 230 of the fixed bracket 200, so that they move backward together. Finally, when the fixing bracket 200 is caught by the stopper 270 located on the support rods 240 and 250, the movement stops, and thus the processing of the vertical hole is completed.

On the other hand, when the stopper 270 adjusts the position on the support rods 240 and 250 by loosening or tightening the fixing screw 272 according to the set processing depth of the vertical hole, the vertical hole of the depth as accurate as the set depth during the drilling operation is processed. Will be.

When the work is completed after such a machining operation, the operator will separate the drilling machine itself from the workpiece 300, wherein the movable bracket 280 and the support rod 240, 250 is the state before the initial operation by the restoring spring 260 It is restored to, and finally caught by the outer surface of the fixing bracket 200 to the locking jaw 251 formed on the end of the second support rod 250, the mobile bracket 280 is completely restored to the state before the initial use .

Drilling machine for vertical hole processing according to the present invention as described above is to be able to process the hole perpendicular to the workpiece while maintaining the correct depth and straightness, unlike in the embodiment of the present invention is modified a part of the component Even if it is carried out by all means that if the modified embodiment includes the essential elements of the present invention basically all should be considered to be included in the technical scope of the present invention.

Drilling machine for vertical hole processing according to the present invention as described above to maintain the processing and processing position maintaining the exact straightness in the vertical direction during vertical hole processing, and also to adjust the machining depth of the vertical hole as needed In this way, it is possible to achieve improved vertical hole processing efficiency and precision.
