Description

Technical Field

[0001] This utility model relates to the field of CNC cutting machine technology, specifically to a main transmission structure for an energy-saving CNC cutting machine for aluminum doors and windows. Background Technology

[0002] In the modern production of aluminum-plastic doors and windows, CNC cutting machines are the core equipment in the profile processing stage. Their role runs through the key process of "raw materials → semi-finished products", directly determining the profile processing accuracy, production efficiency, and the sealing performance and structural stability of the final doors and windows.

[0003] The existing utility model patent with publication number CN201988860U discloses a lightweight gantry CNC cutting machine, including a support frame, mutually perpendicular transverse and longitudinal guide rails, a main controller, and a cutting head and longitudinal transmission device electrically connected to the main controller. The longitudinal guide rail includes a relatively independent active-side double-rail support frame and a driven-side single-sided support frame. One end of the transverse guide rail is connected to the active-side double-rail support frame through the longitudinal transmission device and a slider, and the other end is placed on the driven-side single-sided support frame through support rollers. The double-rail design and split structure of the longitudinal guide rail, as well as the adjustable support feet, simplify the installation process of the cutting machine, facilitate disassembly and debugging, ensure the quality of use, and provide high processing accuracy and reliable performance. The aluminum profile support frame is lightweight, easy to handle, and flexible in transportation, making it widely applicable to the processing and production of various cutting products.

[0004] The aforementioned CNC cutting machine uses only "support rollers" to provide rolling support for the transverse guide rail on the driven side, serving only a basic function of "balancing the center of gravity" and lacking rigid constraint capability. When the span of the transverse guide rail is large or the load on the cutting head increases, the transverse guide rail is prone to sag in the middle, resulting in a "height difference" in the cutting head during transverse movement, directly affecting the straightness and depth consistency of the cut. Meanwhile, the driving side uses "double-axis guide rail + double slider" transmission, which provides stable and uniform sliding resistance; the driven side uses "roller + single-sided guide rail" rolling support, and the rolling resistance is greatly affected by roller wear and lubrication conditions. The difference in resistance between the two can cause "uneven load" on the transverse guide rail during Y-axis movement, affecting cutting accuracy. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a main transmission structure for an energy-saving CNC cutting machine for aluminum doors and windows, which solves the problems of sag in the middle of the guide rail and the impact of different friction forces on the two sides on cutting accuracy.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A main transmission structure for an energy-saving CNC cutting machine for aluminum doors and windows includes a support frame, and a transmission mechanism is provided above the support frame for adjusting the position of the cutting equipment. The transmission mechanism includes: A transverse assembly includes a transverse lead screw and a limiting rod movably mounted on both sides of a support frame. A transverse motor is fixedly mounted on one side of the support frame. A synchronous pulley is fixedly mounted on one end of the transverse lead screw. A synchronous belt is fitted onto the outer side of the synchronous pulley. An arch frame is fixedly mounted below the support frame. The longitudinal component, positioned above the transverse component, is used to adjust the longitudinal position of the cutting device.

[0007] Preferably, the longitudinal component includes a connecting block movably mounted above the transverse lead screw, a linear bearing is fitted inside the connecting block, a slider is fixedly mounted at the bottom of the connecting block, a longitudinal lead screw is movably mounted at the center of the connecting block, limit posts are provided on both sides of the longitudinal lead screw, a longitudinal motor is fixedly mounted above the connecting block, and a mounting bracket is provided above the longitudinal lead screw.

[0008] Preferably, the connection between the transverse lead screw and the support frame is threadless, and the transverse lead screw and the support frame form a rotatable connection, with the threads of the transverse lead screws on both sides of the support frame having the same direction.

[0009] Preferably, the limiting rods are symmetrically arranged on both sides of the transverse lead screw, and both ends are fixedly connected to the support frame. The horizontal motor shaft is fixedly connected to one end of the transverse lead screw on one side. The arch frame is symmetrically installed below the support frame, and the arch frame is also installed between the connecting blocks on the front and rear sides.

[0010] Preferably, the connecting block is slidably connected to the limiting rod via a linear bearing, the connecting block is threadedly connected to the transverse lead screw, the slider below the connecting block contacts the support frame, and the shaft of the longitudinal motor is fixedly connected to one end of the longitudinal lead screw.

[0011] Preferably, the mounting bracket is slidably connected to the limiting post via a linear bearing, and a slider is also installed at the bottom of the mounting bracket, with the bottom slider of the mounting bracket contacting the arch frame between the connecting block.

[0012] Beneficial effects This utility model provides a main drive structure for an energy-saving CNC cutting machine for aluminum doors and windows. Compared with the prior art, it has the following advantages: (1) The main transmission structure of this energy-saving aluminum door and window CNC cutting machine solves the problem of sag in the middle of the guide rail by distributing the load through multiple structures and avoiding deformation in the middle. First, an arch frame is set in the transverse component. The arch frame is not only symmetrically fixed to the bottom of the support frame, but also connected between the connecting blocks on the front and rear sides to form a cross-sectional support structure. When the longitudinal component drives the mounting frame (the cutting equipment is mounted on the mounting frame) to the middle of the support frame or the transverse transmission structure, the arch frame can provide support from the bottom of the connecting blocks and the mounting frame, distributing the load of the cutting equipment and transmission components to both sides of the support frame, avoiding the load from being concentrated in the middle and causing the guide rail or support frame to sag. Second, the transverse screws on both sides rotate synchronously through synchronous pulleys and synchronous belts, driving the connecting blocks on both sides to move synchronously in the transverse direction, so that the force of the connecting blocks on the transverse transmission structure is balanced, and the middle of the structure will not be pulled due to excessive force on one side, further reducing the possibility of sag in the middle and ensuring the consistency of the height when the cutting equipment moves in the transverse direction.

[0013] (2) The main transmission structure of this energy-saving aluminum door and window CNC cutting machine ensures consistent friction on both sides through a symmetrical transmission structure and low-resistance sliding cooperation, avoiding uneven load on both sides from affecting accuracy. On the one hand, the transverse transmission adopts a symmetrical design, with transverse lead screws and limit rods on both sides of the support frame. The transverse lead screws on both sides are linked by synchronous pulleys and synchronous belts. The connecting block and the transverse lead screws on both sides are connected by threads. At the same time, the linear bearings and limit rods slide together. The linear bearings can significantly reduce sliding resistance, and the cooperation method of the linear bearings and limit rods on both sides is completely consistent, ensuring the balance of resistance of transverse movement on both sides from a structural perspective. On the other hand, the slider at the bottom of the connecting block contacts the support frame, and the slider at the bottom of the mounting frame contacts the arch frame. The bottom of the slider is fitted with a ball structure, which can further reduce sliding friction. The installation position and contact surface state of the sliders on both sides are symmetrical, so there will be no uneven load on the transverse movement due to changes in friction resistance on one side, ensuring the straightness of the transverse movement of the cutting equipment, and thus ensuring the consistency of cutting depth and accuracy.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: the main transmission structure of an energy-saving CNC cutting machine for aluminum doors and windows includes a support frame 1, and a transmission mechanism 2 is provided above the support frame 1 for adjusting the position of the cutting equipment. The transmission mechanism 2 includes: The transverse assembly 21 includes transverse lead screws 211 and limiting rods 212 disposed on both sides of the support frame 1. A transverse motor 213 is fixedly installed on one side of the support frame 1. A synchronous pulley 214 is fixedly installed at one end of the transverse lead screw 211. A synchronous belt 215 is fitted onto the outer side of the synchronous pulley 214. An arch frame 216 is fixedly installed below the support frame 1. There is no thread structure at the connection between the transverse lead screw 211 and the support frame 1. The transverse lead screw 211 and the support frame 1 are rotatably connected. The threads of the transverse lead screws 211 on both sides of the support frame 1 are in the same direction. The limiting rods 212 are symmetrically disposed on both sides of the transverse lead screw 211, and both ends are fixedly connected to the support frame 1. The shaft of the transverse motor 213 is fixedly connected to one end of the transverse lead screw 211 on one side. The arch frame 216 is symmetrically installed at the bottom of the support frame 1. The arch frame 216 is also installed between the connecting blocks 221 on the front and rear sides.

[0017] Specifically, the horizontal motor 213 drives the transverse lead screws 211 on both sides to rotate synchronously through the synchronous pulley 214 and synchronous belt 215 (the original text "synchronous pulley and synchronous belt" should be "synchronous pulley 214 and synchronous belt 215" with commas added for clarity) to adjust the position of the connecting blocks 221 on both sides. The two ends of the limiting rod 212 are fixedly connected to the support frame 1, which can limit the rotation angle and movement direction of the connecting blocks 221. The arch frame 216 below the support frame 1 is located below the movement path of the connecting blocks 221, which can distribute the load, reduce local stress, and reduce the deformation of the support frame 1 when the longitudinal component 22 is located at the center of the support frame 1.

[0018] The longitudinal component 22, positioned above the transverse component 21, is used to adjust the longitudinal position of the cutting equipment. The longitudinal component 22 includes a connecting block 221 movably mounted above the transverse lead screw 211. A linear bearing 222 is fitted inside the connecting block 221. A slider 223 is fixedly mounted at the bottom of the connecting block 221. A longitudinal lead screw 224 is movably mounted at the center of the connecting block 221. Limiting posts 225 are provided on both sides of the longitudinal lead screw 224. A longitudinal motor 226 is fixedly mounted above the connecting block 221. A mounting bracket is provided above the longitudinal lead screw 224. The frame 227 and the connecting block 221 are slidably connected to the limiting rod 212 via the linear bearing 222. The connecting block 221 is threadedly connected to the transverse lead screw 211. The slider 223 below the connecting block 221 contacts the support frame 1. The shaft of the longitudinal motor 226 is fixedly connected to one end of the longitudinal lead screw 224. The mounting frame 227 is slidably connected to the limiting post 225 via the linear bearing 222. The bottom of the mounting frame 227 is also equipped with a slider 223. The bottom slider 223 of the mounting frame 227 contacts the arch frame 216 between the connecting block 221 and the connecting block 227.

[0019] Specifically, the connecting block 221 is connected to the transverse lead screw 211 via a threaded structure. Its angle is limited by the limiting rod 212. When the transverse lead screw 211 rotates, it will drive the connecting block 221 to move, thereby adjusting the position of the mounting bracket 227. The two sides of the mounting bracket 227 are connected to the limiting post 225 via linear bearings 222. The angle is limited by the limiting post 225. When the longitudinal motor 226 drives the longitudinal lead screw 224 to rotate, it can adjust the position of the mounting bracket 227. The sliders 223 on both sides below the mounting bracket 227 are in contact with the top surface of the arch frame 216 between the connecting block 221. The bottom of the slider 223 is fitted with a ball structure, which can reduce the friction when the mounting bracket 227 and the connecting block 221 move while providing support for the mounting bracket 227 and the connecting block 221.

[0020] Specifically, the model numbers of the horizontal motor 213 and the vertical motor 226 are ASDA-A3-3021-F. In addition, all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0021] During operation, the cutting equipment is installed below the mounting frame 227. After the horizontal motor 213 starts, its shaft drives one side of the transverse lead screw 211 to rotate. The synchronous pulley 214 at one end of the transverse lead screw 211 rotates accordingly, driving the other side of the transverse lead screw 211 to rotate synchronously through the synchronous belt 215 (the threads of the two transverse lead screws 211 are in the same direction). Since the connecting block 221 is threadedly connected to the transverse lead screw 211, and the linear bearing 222 and the limiting rod 212 (symmetrically arranged on both sides of the transverse lead screw 211, with both ends fixed to the support frame 1) are slidably connected inside the connecting block 221, the connecting block 221 will move laterally along the transverse lead screw 211 and the limiting rod 212. At the same time, the slider 223 at the bottom of the connecting block 221 and the support... The support frame 1 contacts and slides to reduce friction. When the longitudinal position of the cutting equipment needs to be adjusted, the longitudinal motor 226 starts, and its shaft drives the longitudinal lead screw 224, which is movably installed in the center of the connecting block 221, to rotate. The mounting frame 227 forms a sliding connection with the limiting posts 225 on both sides of the longitudinal lead screw 224 through the internal linear bearing 222, and is threadedly connected to the longitudinal lead screw 224. Therefore, it will move longitudinally along the longitudinal lead screw 224 and the limiting posts 225. At the same time, the slider 223 at the bottom of the mounting frame 227 contacts and slides with the arch frame 216 between the connecting block 221 (symmetrically installed at the front and rear under the support frame 1 and between the front and rear connecting blocks 221), further reducing the friction of movement. Finally, the precise control of the cutting equipment position is achieved through the coordinated adjustment of the lateral and longitudinal directions.
