[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Reference Figure 1-4The gantry drilling machine shown in the figure comprises a machine tool base 1, a gantry body 2, an L-shaped movable plate, and a drilling rig. It should be noted that, in this embodiment, the installation method of the gantry body 2, the L-shaped movable plate, and the drilling rig can refer to the technical content adopted in a gantry movable CNC plane drilling machine disclosed in the Chinese patent with publication number CN216938497U in the prior art, which will not be repeated here. A processing plate 3 is slidably installed on the top of the machine tool base 1 through a moving component, and a supporting component and a cleaning component are arranged at the bottom of the processing plate 3. Two fixed plates 10 are fixedly installed on the top of the bed base 1, and two slide grooves are provided on the top of the two fixed plates 10. Limit rods 11 are slidably installed in the four slide grooves, and the sides of each of the two matching limit rods 11 are jointly installed with extrusion plates 12. Lifting grooves are provided on the opposite sides of the gantry body 2, and lifting blocks 13 are slidably installed in the two lifting grooves through lifting components. Connecting rods 17 are rotatably installed on the opposite sides of the two lifting blocks 13, and the other ends of the two connecting rods 17 are rotatably installed on the sides of the two extrusion plates 12 respectively.

[0023] With the help of the above structure, when in use, the plate is first placed on the top of the processing plate 3, and then the two lifting blocks 13 are driven downward by the lifting assembly, and then the two extrusion plates 12 are driven to move synchronously towards each other under the action of the two connecting rods 17, and the plate is pushed to the middle and fixed on both sides. This not only fixes the plate, but also avoids the vibration caused by the drilling rig during work from interfering with it and affecting the drilling quality. The overall practicality is strong.

[0024] like Figure 1 As shown, the moving assembly includes two screw rods 5, and two side plates 4 are fixedly installed on the top of the machine tool base 1. One end of the two screw rods 5 is rotatably installed on the side of one of the side plates 4, and the other ends of the two screw rods 5 extend to the outside of the other side plate 4 and are connected through a transmission unit. The processing plate 3 is threadedly installed on the two screw rods 5. The advantage of this arrangement is that through the arrangement of the two screw rods 5, the processing plate 3 can be driven to move horizontally.

[0025] Specifically, when the position of the plate needs to be adjusted, the two screw rods 5 are rotated, and the processing plate 3 is driven to achieve horizontal movement under the action of the threads, thereby achieving the function of adjusting the horizontal position of the plate. The adjustment operation is simple and convenient for practical use.

[0026] like Figure 1 As shown, the transmission unit includes two first sprockets 6, which are respectively fixedly sleeved on two screw rods 5, and a first chain is installed on the two first sprockets 6 in meshing relationship with each other. A mobile motor 7 is fixedly installed on the side of one of the side plates 4, and an output shaft of the mobile motor 7 is connected to the end of one of the screw rods 5. The advantage of such an arrangement is that, through the arrangement of the two first sprockets 6, the two screw rods 5 can be driven to rotate synchronously.

[0027] Specifically, the moving motor 7 is started to drive one of the screw rods 5 to rotate, and then the other screw rod 5 is driven to rotate synchronously under the joint action of the two first sprockets 6 and the first chain, so that the processing plate 3 can realize the horizontal movement function through the synchronous rotation of the two screw rods 5.

[0028] like Figure 2 As shown, the support assembly includes two support rollers 8, and two rectangular grooves are provided at the bottom of the processing plate 3. Rotating rods are rotatably installed on the relative inner walls of the two rectangular grooves. The two support rollers 8 are respectively fixedly sleeved on the two rotating rods, and the peripheral outer walls of the two support rollers 8 are both in contact with the machine tool base 1. The advantage of such an arrangement is that, through the arrangement of the two support rollers 8, a certain supporting function can be played on the processing plate 3.

[0029] Specifically, when the processing plate 3 moves horizontally, the supporting rollers 8 provide support to the processing plate 3 to a certain extent, thereby preventing the processing plate 3 from causing extrusion damage to the two screws 5, and providing better protection.

[0030] like Figure 2 As shown, the cleaning assembly includes two cleaning brushes 9, both of which are fitted with the top of the machine tool base 1, and both of which are fixedly installed on the bottom of the processing plate 3. Two waste holes are provided on the top of the machine tool base 1, and the two waste holes are respectively matched with the two cleaning brushes 9. The advantage of such an arrangement is that, through the arrangement of the two cleaning brushes 9, the top of the machine tool base 1 can be cleaned through the horizontal movement of the processing plate 3.

[0031] Specifically, when the drilling machine is working, iron filings are generated. When the processing plate 3 moves horizontally, it drives the two cleaning brushes 9 to move horizontally synchronously to clean the iron filings on the top of the machine tool base 1, thereby brushing them into the waste hole for collection.

[0032] like Figure 4 As shown, the lifting assembly includes two screw rods 14, the two ends of the two screw rods 14 are rotatably mounted on the opposite inner walls of the two lifting slots, the two screw rods 14 are connected by a linkage unit, and the two lifting blocks 13 are respectively threadedly mounted on the two screw rods 14. The advantage of this arrangement is that the lifting block 13 can be driven to achieve the lifting function through the arrangement of the two screw rods 14.

[0033] Specifically, when the two screw rods 14 rotate, they drive the two lifting blocks 13 to move downward synchronously, and then drive the two extrusion plates 12 to move toward each other synchronously under the action of the two connecting rods 17, thereby clamping and fixing the left and right sides of the plate, improving its stability during drilling.

[0034] like Figure 4As shown, the linkage unit includes two second sprockets 15, and the two second sprockets 15 are respectively fixedly sleeved on the two screw rods 14, and the second chain is installed on the two second sprockets 15 in meshing relationship with each other. A motor slot is opened on the bottom inner wall of one of the lifting slots, and a lifting motor 16 is fixedly installed in the motor slot. The output shaft of the lifting motor 16 is connected to the bottom end of one of the screw rods 14. The advantage of such a setting is that, through the setting of the two second sprockets 15, the function of driving the two screw rods 14 to rotate synchronously can be realized, thereby realizing the synchronous fixation of the two sides of the plate.

[0035] Specifically, the lifting motor 16 is started to drive one of the screw rods 14 to rotate, and then the other screw rod 14 is driven to rotate synchronously under the action of the two second sprockets 15 and the second chain, thereby driving the two lifting blocks 13 to rise and fall synchronously, so as to facilitate the synchronous fixing of the two sides of the plate.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
