Description

Technical Field

[0001] The utility model relates to the technical field of punching devices, in particular to a punching device for producing office desks and chairs. Background Art

[0002] During the processing of wooden office desks and chairs, it is necessary to punch holes in the boards. For example, a wooden floor punching device disclosed in the authorization announcement number CN219213410U starts the motor to drive the gear and the transmission belt to rotate, and the transmission belt drives the clamping teeth and the ring to rotate. At the same time, the thread set inside the ring drives the threaded rod and the clamping block to move horizontally, so that the clamping block clamps the wooden board. The two groups of clamping blocks set symmetrically move toward the center at the same time, and wooden boards of different sizes can be fixed at the center of the processing table. Wooden boards of different sizes can be clamped and fixed, which solves the problem that wooden boards of different sizes are inconvenient to fix when punching holes.

[0003] The currently available punching equipment, such as the above-mentioned prior art, can pre-fix the plate, but the position of each hole in the plate may be different, and multiple holes may need to be punched on each plate. After the above-mentioned fixing mechanism fixes the plate, the position of the hole is also limited, and before fixing, the staff is required to adjust the punching position of the plate to correspond to the position of the drilling drill. When the staff adjusts, they can only watch with the naked eye, and deviations may occur, resulting in the offset of the punched holes and defective products.

[0004] Therefore, we propose a punching device for producing office desks and chairs to solve the above problems. Utility Model Content

[0011] Preferably, the light spot emitted by the laser lamp and the axis of the drill bit are on the same vertical line.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] This punching device for producing office desks and chairs has a laser lamp arranged on one side of the drill bit. The light spot emitted by the laser lamp is on the same vertical line as the axis of the drill bit. Before drilling, a plate with a punching mark is placed on the workbench. The laser lamp is turned on, the mark is moved to the light spot, and then the fixing mechanism is started to move down to fix the plate, and then drilling can be performed. This is convenient for the staff to control the mark to correspond to the drill bit position, avoiding the hole offset after drilling. BRIEF DESCRIPTION OF THE DRAWINGS
