[0002] Tabletop heating furnaces are commonly used heat treatment equipment in industrial production, and opening the furnace door is an important step in their manufacturing process.

[0003] However, when existing furnace door drilling devices are used to drill holes in furnace doors, workers need to place the furnace door on a workbench and drill the hole using a bench drill. Not only is the furnace door prone to tilting due to drilling vibration, but it is also difficult to move the furnace door when drilling to the next position because the furnace door is heavy. Utility Model Content

[0015] 2. This utility model achieves precise positioning of the drill bit by activating the first and second linear motors, which drive the drill bit to move left, right, forward, and backward to a suitable position, thus enabling the drill bit to move to the target position and ultimately achieving precise adjustment of the drilling position of the furnace door.

[0016] 3. This utility model activates the second dual-axis cylinder, causing the piston rod of the second dual-axis cylinder to move upward, thereby driving the top frame to rise.

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Reference Figures 1-4This utility model provides a device for machining and opening holes in the door of a tabletop heating furnace, including a base plate 5. A second dual-axis cylinder 19 is bolted to the bottom of the base plate 5, and the piston rod of the second dual-axis cylinder 19 passes through the base plate 5 and is bolted to a top frame 18. The top of the top frame 18 has multiple rolling grooves, each containing a ball bearing 17. The ball bearing 17 greatly reduces the friction between the top frame 18 and the furnace door. By activating the second dual-axis cylinder 19, the piston rod of the second dual-axis cylinder 19 moves the top frame 18 upward, and the top frame 18 moves the furnace door upward, thus facilitating the removal of the furnace door. The top of the base plate 5 is bolted to a first support frame 2. Two support blocks 7 are bolted to the top of the base plate 5, and two baffles 8 are bolted to the top of each support block 7. The baffles 8 allow for quick positioning of the furnace door. A first dual-axis cylinder 1 is bolted to the top of the first support frame 2, and the piston rod of the first dual-axis cylinder 1 passes through the first support frame 2 and is bolted to a first fixing plate 3. Two fixing brackets 4 are bolted to the bottom of the first fixing plate 3, and each fixing bracket 4 has a sloping surface 9 on one side. The top of the base plate 5 is bolted to... Multiple second fixing plates 13 are provided, and each second fixing plate 13 has a telescopic rod 12 bolted to one side. A tension spring 11 is fitted around the outer circumference of each telescopic rod 12, with one end of the tension spring 11 fixed to the second fixing plate 13 and the other end fixed to the connecting plate 10. The tension spring 11 allows for quick resetting of the connecting plate 10. The other end of each pair of adjacent telescopic rods 12 is bolted to the connecting plate 10. Each pair of connecting plates 10 has a locking block 14 bolted to one side. The bottom of the first fixing plate 3 is equipped with a drilling mechanism for drilling holes in the furnace door. The first dual-axis cylinder 1 is activated. The piston rod of the first dual-axis cylinder 1 drives the first fixed plate 3, the two fixed brackets 4, and the drilling mechanism to move downward. The inclined surfaces 9 on one side of the two fixed brackets 4 press the two connecting plates 10 respectively, causing the two connecting plates 10 to move inward. The two connecting plates 10 drive the two locking blocks 14 to move inward, so that the locking blocks 14 lock the furnace door placed on the top of the connecting plate 10, thereby fixing the furnace door. This prevents the furnace door from easily deflecting due to drilling vibration when drilling, and also makes it difficult to move the furnace door when drilling the next position, as the furnace door is relatively heavy.

[0024] In this utility model, the drilling mechanism is a first linear motor 15, which is fixed to the bottom of the first fixing plate 3 by bolts. A second linear motor 16 is located at the bottom of the first linear motor 15, and a second support frame 20 is located at the bottom of the second linear motor 16. A motor is fixed to the inner wall of the bottom of the second support frame 20 by bolts, and the output shaft of the motor passes through the second support frame 20 and is fixed to a protrusion 21 by bolts. A groove 22 is formed at the bottom of the protrusion 21, and a drill bit 23 is located inside the groove 22. A limiting mechanism for fixing the drill bit 23 is provided on the inner circumference of the protrusion 21. The limiting mechanism is a threaded rod 24, and one end of the threaded rod 24 is welded with... The knob has multiple anti-slip grooves evenly distributed on its outer circumference, allowing for easier rotation of the threaded rod 24. The threaded rod 24 is inserted into the inner circumference of the protrusion 21 and is threadedly connected to the drill bit 23. By rotating the threaded rod 24 counterclockwise, the threaded rod 24 is disengaged from the drill bit 23, thus facilitating the replacement of the drill bit 23. By activating the first linear motor 15, the first linear motor 15 drives the second linear motor 16 to move left or right to the appropriate position. The second linear motor 16 then drives the second support frame 20 and the drill bit 23 to the appropriate position, thereby achieving adjustment of the drilling position of the furnace door.

[0025] The working principle of this utility model is as follows: The furnace door is placed on top of the two support blocks 7, and then the first linear motor 15 is started. The first linear motor 15 drives the second linear motor 16 to move left and right to a suitable position. The second linear motor 16 drives the second support frame 20 and the drill bit 23 to a suitable position. Then the motor is started, and the motor drives the drill bit 23 to rotate. Then the first dual-axis cylinder 1 is started. The piston rod of the first dual-axis cylinder 1 drives the first fixed plate 3, the two fixed frames 4, and the drilling mechanism to move downward. The inclined surface 9 on one side of the two fixed frames 4 presses the two connecting plates 10 respectively, causing the two connecting plates 10 to move inward. The two connecting plates 10 drive the two locking blocks 14 to move inward, so that the locking blocks 14 lock the furnace door placed on top of the connecting plate 10. Continue to move downward, and the drill bit 23 drills a hole in the furnace door.
