Description

Technical Field

[0001] The utility model relates to the technical field of furniture processing, in particular to a hole punching machine. Background Art

[0002] Furniture is one of the indispensable facilities in people's lives. With the development of society, the types of furniture are becoming more and more diversified, making people's living environment more and more comfortable. In the process of furniture production, it is often necessary to drill holes in the boards to facilitate the fixing and installation of the boards.

[0003] A Chinese patent discloses a wood hole drilling machine for furniture processing (authorization announcement number CN217256885U), and its specification states that "the servo motor is started, and the second slider is driven to move left and right by rotating the threaded rod, so that the position of the drill bit corresponds to the position on the upper surface of the wooden board where a hole needs to be drilled. The motor is started, and the drill bit is driven to drill through the rotating shaft and the connecting block. The cylinder is started and the connecting rod is pushed, so that the limit block moves downward inside the limit groove, and the drill bit is driven downward to drill a hole in the wooden board." However, although the above-mentioned drill bit can change its own position by rotating the threaded rod, there is a lack of corresponding positioning measures between the drill bit and the designated hole opening position on the wooden board. That is to say, when the drill bit moves down for drilling, it cannot be guaranteed that the drill bit and the hole opening position on the wooden board are on the same vertical line, which easily leads to problems such as deviation in the hole opening position.

The driving end of the servo motor 51 passes through the vertical plate 2 and is fixedly connected to the driving gear 52. The driven gear 52 is meshed with the driven gear 53. An adjusting rod 54 is fixedly passed through the interior of the driven gear 53. One end of the adjusting rod 54 is fixedly connected to a mounting frame 55. A laser emitter 56 is fixedly connected to the bottom of the mounting frame 55. The other end of the adjusting rod 54 is rotatably connected to the vertical plate 2 through a bearing. The servo motor 51 is fixedly connected to the vertical plate 2. The mounting frame 55 is an "L"-shaped structure. The center point of the laser emitter 56 is on the same vertical line as the center point of the drill bit 45. The vertical laser beam emitted by the laser emitter 56 can form a positioning point on the plate, so that the user can accurately find the position to be drilled on the plate to prevent the drill bit 45 from having a position deviation during drilling, resulting in the quality of the drilling not meeting the standards, thereby improving the drilling accuracy.

[0022] The horizontal plate 4 is also provided with a presser 6, which includes an electric push rod 61, a pad 62 and a limit rod 63. The telescopic end of the electric push rod 61 is fixedly connected to the pad 62, the bottom of the pad 62 is fixedly connected to two limit rods 63, the bottom of the limit rod 63 is fixedly connected to a pressing plate 64, the center of the pressing plate 64 is penetrated by a drill hole 65, the fixed end of the electric push rod 61 is fixedly connected to the top center of the horizontal plate 4, the center point of the drill hole 65 and the center point of the drill bit 45 are on the same vertical axis.

At this time, when the drill bit 45 continuously moves from the drill hole 65 to the plate to open a hole, the plate is not prone to cracking and other problems, reducing the probability of damage to the plate itself.

[0023] The model of the electric motor 44 is YE2, and the model of the servo motor 51 is ACSM110-G04030LZ.

[0024] Working principle: When using this device, place the plate on the processing table 1 and make the plate under the four clamping plates 32. At this time, control the servo motor 51 to rotate forward 90°. After the servo motor 51 rotates forward, it can drive the driving gear 52 to rotate forward 90°, and then drive the driven gear 53 to reverse 90°. After the driven gear 53 reverses, it can drive the adjusting rod 54, the mounting frame 55 and the laser emitter 56 to reverse 90°. At this time, the laser emitter 56 is in a vertical state, and the center point of the laser emitter 56 is on the same vertical line as the center point of the drill bit 45. Then turn on the laser emitter 56. After the laser emitter 56 is turned on, a laser spot can be formed on the plate. Then the user moves the plate until the area to be drilled on the plate is moved to the laser spot, and then holds the threaded rod 31 and rotates it, so as to drive the clamping plate 32 to move down. The plate can be fixed at this time, and then the servo motor 51 is controlled to reverse. Under the action of the driving gear 52 and the driven gear 53, the adjusting rod 54, the mounting frame 55 and the laser emitter 56 can be driven to rotate 90° forward. At this time, the mounting frame 55 and the laser emitter 56 can be removed from the bottom of the drill bit 45 to prevent them from affecting the normal hole opening. Then the electric push rod 61 is controlled to be shortened. After the electric push rod 61 is shortened, the pad 62, the limit rod 63 and the pressure plate 64 can be driven to move downward until the pressure plate 64 is against the plate. At this time, the area to be opened can be located in the drill hole 65, and then the cylinder 41 and the motor 44 are controlled to work. After the motor 44 works, the drill bit 45 can be driven to rotate. At this time, the cylinder 41 is extended, so that the rotating drill bit 45 can be driven to pass through the drill hole 65 and the plate. Finally, the drill bit 45 moves into the groove 11, thereby completing the hole opening work.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
