[0016] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0017] In the embodiment, Figure 1-3 A drilling and fixing device for metal doors and windows is provided, comprising a base 1, on which a fixing plate 2 is fixedly mounted, and a surface of the fixing plate 2 is provided with a through hole 3 for the passage of a pipe. A clamping assembly 4 for fixing the pipe is provided on one side surface of the fixing plate 2, and a centering assembly 5 is provided on the other side surface, which is used to cooperate with the clamping assembly 4 to limit the pipe. A bracket 6 is provided near the feeding end of the pipe on the base 1, and a feeding device 7 for pushing the pipe is provided on the bracket 6. The pipe to be processed is placed at the feeding end of the device. At this time, one end of the pipe is aligned with and close to the through hole 3 on the fixing plate 2, ready for subsequent positioning and fixing, and the pipe is pushed by the feeding device 7. When the pipe passes through the centering assembly 5, the centering assembly 5 is started to limit the feeding direction of the pipe and reduce the friction force when the pipe is fed. When the pipe is gradually fed to the punching position of the punching device, the supporting assembly 4 is turned on to fix the pipe to ensure that the pipe remains stable and motionless during the processing to prevent processing errors caused by vibration or offset.

[0018] Reference Figure 1-3, wherein the clamping assembly 4 includes a shell 41 fixedly mounted on one side surface of the fixing plate 2, a feed channel 42 communicating with the through hole 3 is provided on the shell 41, a plurality of clamping jaws 43 equidistantly distributed in a ring shape according to the feed channel 42 are slidably connected to one side surface of the shell 41, a drive shaft 44 is rotatably connected to the shell 41, and one end of the drive shaft 44 is connected to the output end of the driving device, and a first bevel gear 45 is fixedly mounted on the other end, a second bevel gear 46 meshing with the first bevel gear 45 is rotatably connected in the shell 41, and a spiral groove 47 is provided on the side surface of the second bevel gear 46 away from the first bevel gear 45, and a protrusion 48 matching the spiral groove 47 is provided on the clamping jaw 43;

[0019] Through the above-mentioned structural setting, the driving device adopts the stepping motor of the prior art, which is the power source of the clamping assembly 4. When the pipe is loaded, the clamping jaws 43 are in an open state, and the feeding channel 42 is unobstructed, allowing the pipe to enter smoothly. After starting the driving device, the power is transmitted to the driving shaft 44 through the output end, and the driving shaft 44 drives the first bevel gear 45 to rotate. Through the gear power transmission, the second bevel gear 46 also rotates accordingly. As the second bevel gear 46 rotates, the spiral groove 47 thereon and the protrusion 48 on the clamping jaw 43 move relative to each other. Due to the design of the spiral groove 47, the protrusion 48 moves along a specific trajectory under the guidance of the spiral groove 47, thereby driving the clamping jaws 43 to move toward the center or outward. When the clamping jaws 43 move toward the center, they will clamp the pipe; otherwise, they will release the pipe. When the pipe enters the clamping area through the feeding channel 42, the driving device starts and drives the clamping jaws 43 to clamp the pipe. At this time, the pipe is firmly fixed at the predetermined position of the perforation 3, ready for subsequent drilling operations.

[0020] Reference Figure 1-3 , wherein the number of the clamping jaws 43 is not less than three, and an anti-slip groove is provided on the surface of one side of the clamping jaw 43 close to the feed channel 42;

[0021] Through the above-mentioned structural setting, the number of the clamping jaws 43 is at least three, and they are distributed on the one side surface of the shell 41 in a circular equidistant manner and arranged around the feed channel 42, ensuring that the pipe can be clamped stably enough regardless of its diameter and shape. The anti-slip grooves on the clamping jaws 43 increase the friction between the clamping jaws and the pipe to prevent the pipe from sliding or deflecting during the clamping or drilling process.

[0022] Reference Figure 1-3 , wherein the centering component 5 includes a mounting seat 51, and a plurality of mounting seats 51 are fixedly mounted on a surface of the fixed plate 2 on one side away from the clamping component 4 and are equidistantly distributed in a ring shape according to the through hole 3, and an electric push rod 52 is arranged on the mounting seat 51, and a roller 53 is arranged at the telescopic end of the electric push rod 52;

[0023] Through the above-mentioned structural setting, the electric push rod 52 drives the roller 53 to move, and the roller 53 helps to reduce friction and resistance, so that the pipe is smoother when being fed forward, and can also cooperate with the clamping component 4 to fix the pipe.

[0024] Reference Figure 1-3 , wherein the feeding device 7 includes a driving shaft 71 rotatably connected to the bracket 6, and one end of the driving shaft 71 is connected to the output end of the driving motor, and the other end is provided with a universal coupling 72, and the end of the universal coupling 72 away from the driving shaft 71 is provided with a driven shaft 73, and the driven shaft 73 is slidably connected to the bracket 6, and a feeding wheel 74 is provided on the driven shaft 73;

[0025] Through the above-mentioned structural arrangement, a vertically arranged slide groove is opened on the bracket 6, and a slider is slidably connected in the slide groove. The driven shaft 73 is arranged through and rotatably connected to the slider, and the universal coupling 72 has a telescopic function, so that the height of the feeding wheel 74 can be adjusted according to the size of the pipe. When the driving shaft 71 rotates, the universal coupling 72 transmits the power with adjusted direction to the driven shaft 73, and drives the feeding wheel 74 thereon to rotate together, thereby realizing pipe loading.
