Description

Technical Field

[0001] This invention relates to the field of engraving and milling machine technology, specifically to a horizontal high-precision profile engraving and milling machine. Background Technology

[0002] In the field of metal profile processing, the engraving and milling machine is a high-speed CNC machine tool that integrates engraving and milling functions. Based on the traditional engraving machine, the engraving and milling machine increases the spindle power and servo motor power, improves the load-bearing capacity of the machine bed, and maintains the high-speed operation of the spindle, thereby achieving stronger cutting ability and higher processing accuracy. According to the spatial position of the spindle, engraving and milling machines can be divided into vertical engraving and milling machines and horizontal engraving and milling machines. The spindle of the vertical engraving and milling machine is arranged vertically, which is suitable for drilling, cutting and complex contour processing. The spindle of the horizontal engraving and milling machine is arranged horizontally, which is more suitable for cutting and shaping larger and heavier workpieces, and has higher material removal efficiency. In the field of profile processing, especially for the contour processing of long strip metal profiles, the horizontal layout of the engraving and milling machine has unique advantages. The profile is usually clamped in the horizontal direction, and the horizontal arrangement of the spindle can realize high-precision milling of the side contour of the profile. Existing horizontal engraving and milling machines, such as the one disclosed in CN213469706U, utilize the cooperation between a first slider and a first slide rail to allow the first slider to slide on the first slide rail. The cooperation between the worktable and the first slide rail allows the worktable to move. The cooperation between the second slide rail and the second slider allows the second slider to slide left and right on the second slide rail. The cooperation between the tooling fixture and the second slide rail allows the tooling fixture to move left and right. This allows the workpiece to be processed at various positions above the tooling fixture, thus improving efficiency. However, when the above-mentioned existing technology is used, the debris generated during the processing of the workpiece is very likely to fall into the slide rail, which can easily cause the debris to interfere with the smooth sliding of the slider and the slide rail, making the engraving and milling machine prone to failure. In addition, after a period of use, the existing engraving and milling machine needs to be cleaned with an air gun to avoid the debris interfering with its accuracy. This not only increases the labor intensity of the workers, but is also not conducive to energy conservation and emission reduction. Therefore, a high-precision horizontal profile engraving and milling machine is needed to solve the above problems. Summary of the Invention

[0003] The purpose of this invention is to provide a profile horizontal high-precision contour engraving and milling machine to solve the problems mentioned in the background art, such as the existing horizontal engraving and milling machines being easily interfered with by debris, requiring regular cleaning, which leads to increased labor intensity for workers and energy waste.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A horizontal high-precision profile engraving and milling machine includes a base and a mounting groove on the vertical side wall of the base. Both sides of the mounting groove have limiting slots extending to the outside of the base. A fixing frame is slidably connected within the mounting groove. The two sides of the fixing frame have protrusions that slide through the corresponding limiting slots. A fixing plate for mounting an engraving and milling cutter is provided on the fixing frame. The lower end of a Z-axis adjusting screw is connected to the mounting groove by a bearing, and the upper end of the Z-axis adjusting screw is also connected by a bearing that extends through the mounting groove. The Z-axis adjusting screw is threaded through the fixing frame. The upper end of the vertical part of the base is equipped with a mounting plate... The base is equipped with a Z-axis adjusting motor for connecting to the Z-axis adjusting lead screw. A Y-axis adjusting motor is mounted on the upper surface of the horizontal part of the base. A worktable is mounted above the base. A tooling fixture for fixing the profile is mounted above the worktable. An X-axis adjusting motor is mounted on the upper surface of the worktable. Protective transmission mechanisms are provided between the worktable and the tooling fixture, as well as between the base and the worktable. The protective transmission mechanism includes lead screw shafts mounted at the output ends of both the Y-axis and X-axis adjusting motors. A vibration-type impurity removal mechanism is mounted on the protective transmission mechanism.

[0005] Preferably, the protective transmission mechanism further includes slide rails provided on the upper surface of the horizontal part of the base and the upper surface of the worktable, and corresponding sliders are slidably connected on the slide rails, and each lead screw shaft is threadedly connected with a corresponding nut sleeve.

[0006] Preferably, both the slider and the nut sleeve are equipped with support frames, and the support frame between the base and the worktable is fixedly connected to the lower surface of the worktable, and the support frame between the worktable and the tooling fixture is fixedly connected to the lower surface of the tooling fixture.

[0007] Preferably, the upper surface of the horizontal part of the base and the upper surface of the worktable are both provided with baffles, and the number of baffles is equal to the sum of the number of slide rails and lead screw shafts. Each group of baffles is provided with 2 baffles, and the 2 baffles in each group are symmetrically arranged below the corresponding support frame. The ends of the 2 baffles in each group are connected by a support block.

[0008] Preferably, a stop frame is provided directly above both the slide rail and the lead screw shaft, and a limit block is installed on the lower surface of both ends of the stop frame. The limit block and the support block are arranged in a one-to-one correspondence. The support frame moves through the gap between the stop bar and the stop frame, and the gap between the stop bar and the stop frame is greater than the maximum distance the stop frame can move on the vertical plane.

[0009] Preferably, the cross-section of the baffle is an inverted V-shape, which is used to allow the debris generated during the milling process to slide down the outer wall of the baffle and avoid the debris from accumulating on the baffle. The horizontal part of the base and the worktable are both provided with hollow grooves, and hollow grooves are provided on both sides of each baffle, so that the debris sliding down from the outer wall of the baffle can be discharged from the milling machine through the hollow grooves.

[0010] Preferably, the vibration-type impurity removal mechanism includes a limiting groove provided on the lower surface of the limiting block, and the upper end of the limiting shaft extends movably into the inside of the limiting groove. The lower end of the limiting shaft is fixedly connected to the corresponding support block, and a spring nested on the outside of the corresponding limiting shaft is provided between the support block and the limiting block.

[0011] Preferably, the inner side of the retaining frame is evenly distributed with paddles, and the outer sides of the slider and the nut sleeve are both distributed with spring pieces, and the spring pieces are connected between adjacent paddles.

[0012] Preferably, the cross-sections of the spring and the paddle are both isosceles triangles, which facilitates the reciprocating movement of the stop frame by the spring pressing the paddle when the slider and nut sleeve move.

[0013] Preferably, an inclined guide plate is fixedly connected to the vertical side of the base, and the guide plate is located below the fixed plate.

[0014] Compared with the prior art, the beneficial effects of this invention are: the profile horizontal high-precision contour engraving and milling machine adopts a protective transmission mechanism, which can prevent the debris generated during profile processing from falling onto the slide rail, slider, nut sleeve, and lead screw shaft, thereby preventing the movement of the slider and nut sleeve from being obstructed. This helps to ensure the accuracy of the movement of the worktable and tooling fixture, thus ensuring the accuracy of the engraving and milling machine. In addition, it can greatly extend the periodic cleaning cycle, which not only helps to reduce the labor intensity of workers, but also reduces the energy consumption caused by cleaning. 1. The installation of baffles and baffles prevents debris from the processed profiles from falling onto the slide rails and lead screw shafts. Furthermore, the installation of support frames prevents debris from falling onto the slider and nut sleeve, thus avoiding obstruction of their movement. This not only allows the slider and nut sleeve to move smoothly but also ensures the accuracy of their movement, thereby contributing to the precision of the engraving and milling machine. In addition, the hollowed-out grooves facilitate the discharge of debris from the engraving and milling machine, greatly reducing the frequency of regular cleaning. This not only reduces the labor intensity of the workers but also reduces the energy consumption generated by cleaning the engraving and milling machine. 2. The spring and paddle are designed so that the slider and nut can move up and down the baffle when they move. In conjunction with the spring, limit shaft and limit groove, the baffle can vibrate, which helps to shake off the debris stuck to it. This ensures that the debris that falls onto the baffle can slide off smoothly, thereby further reducing the cleaning cycle. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-10 The present invention provides the following technical solution: Example 1: To address the problem that in traditional horizontal engraving and milling machines, debris easily falls onto the transmission mechanism, leading to transmission malfunctions and affecting accuracy, the following technical solution is provided: A profile horizontal high-precision contour engraving and milling machine includes a base 1 and a mounting groove 2 on its vertical side wall. Both sides of the mounting groove 2 are provided with limiting slots 3 extending to the outside of the base 1. A fixing frame 4 is slidably connected within the mounting groove 2. The two sides of the fixing frame 4 protrude and slide through the corresponding limiting slots 3. A fixing disc 5 for mounting the engraving and milling cutter is provided on the fixing frame 4. The lower end of a Z-axis adjusting screw 6 is connected to the mounting groove 2 via a bearing, and the upper end of the Z-axis adjusting screw 6... An end bearing is installed through the mounting groove 2, and a Z-axis adjusting screw 6 is threaded through the fixing bracket 4. A Z-axis adjusting motor 7 for connecting with the Z-axis adjusting screw 6 is installed on the upper vertical part of the base 1. A Y-axis adjusting motor 11 is installed on the upper surface of the horizontal part of the base 1, and a worktable 8 is installed above the base 1. A tooling fixture 9 for fixing the profile is installed above the worktable 8, and an X-axis adjusting motor 12 is installed on the upper surface of the worktable 8. Protective transmission mechanisms are provided between the worktable 8 and the tooling fixture 9, as well as between the base 1 and the worktable 8. The protective transmission mechanism includes a screw shaft 26 installed at the output end of both the Y-axis adjusting motor 11 and the X-axis adjusting motor 12.

[0019] In a preferred embodiment of the invention, the protective transmission mechanism further includes slide rails 22 provided on the upper surface of the horizontal part of the base 1 and the upper surface of the worktable 8, and corresponding sliders 23 are slidably connected to the slide rails 22. Each lead screw shaft 26 is threaded with a corresponding nut sleeve 27. Support frames 15 are installed on the sliders 23 and the nut sleeves 27. The support frame 15 between the base 1 and the worktable 8 is fixedly connected to the lower surface of the worktable 8, and the support frame 15 between the worktable 8 and the tooling fixture 9 is fixedly connected to the lower surface of the tooling fixture 9.

[0020] In the above technical solution, the support frame 15 enables the slider 23 to move on the slide rail 22 and the nut sleeve 27 to move on the lead screw shaft 26, thereby driving the worktable 8 and tooling fixture 9 equipped with the support frame 15 to move.

[0021] In a preferred embodiment of the invention, both the upper surface of the horizontal part of the base 1 and the upper surface of the worktable 8 are provided with baffles 21, and the number of baffles 21 groups is equal to the sum of the number of slide rails 22 and lead screw shafts 26. Each group of baffles 21 is provided with 2 baffles, and the 2 baffles 21 in each group are symmetrically arranged below the corresponding support frame 15. The ends of the 2 baffles 21 in each group are connected by a support block 19.

[0022] In the above technical solution, by setting the baffle 21, debris can be prevented from entering the slide rail 22 and the lead screw shaft 26, thereby preventing debris from damaging the connection between the slide rail 22 and the slider 23 and the connection between the lead screw shaft 26 and the nut sleeve 27.

[0023] In a preferred embodiment of the invention, a baffle 13 is provided directly above the slide rail 22 and the lead screw shaft 26, and a limit block 16 is installed on the lower surface of both ends of the baffle 13. The limit block 16 and the support block 19 are arranged in a one-to-one correspondence. The support frame 15 moves through the gap between the baffle 21 and the baffle 13, and the gap between the baffle 21 and the baffle 13 is greater than the maximum distance that the baffle 13 can move on the vertical plane.

[0024] In the above technical solution, the baffle 13 is provided so that the debris generated by the processing profile can slide down the outer surface of the baffle 13, thereby preventing the debris from falling below the baffle 13 and affecting the normal movement of the slider 23 and the nut sleeve 27.

[0025] In a preferred embodiment of the invention, the cross-section of the baffle 13 is an inverted V-shape, which is used to allow the debris generated during the milling process to slide down the outer wall of the baffle 13 and avoid the debris from accumulating on the baffle 13. The horizontal part of the base 1 and the worktable 8 are both provided with hollow grooves 14, and the hollow grooves 14 are provided on both sides of each baffle 13, so that the debris sliding down from the outer wall of the baffle 13 can be discharged from the milling machine through the hollow grooves 14.

[0026] In the above technical solution, the debris generated during the processing of the profile can fall into the hollow groove 14 along the baffle frame 13 and then be discharged from the engraving and milling machine, which helps to extend the cleaning cycle and reduce the labor intensity of the workers.

[0027] In a preferred embodiment of the invention, an inclined guide plate 10 is fixedly connected to the vertical side of the base 1, and the guide plate 10 is disposed below the fixed disk 5.

[0028] In the above technical solution, the guide plate 10 can prevent debris from accumulating at the intersection of the horizontal and vertical parts of the base 1, thereby reducing the amount of debris on the engraving and milling machine.

[0029] according to Figures 1-6 When in use, the engraving cutter can be installed on the fixed plate 5, and the Z-axis adjusting screw 6 can be rotated by the Z-axis adjusting motor 7, so that the position of the fixed frame 4 can be adjusted by the limiting through groove 3. In addition, the Y-axis adjusting motor 11 and the X-axis adjusting motor 12 can control the rotation of the corresponding lead screw shaft 26 respectively, and the nut sleeve 27 can drive the worktable 8 and the tooling fixture 9 to move through the support frame 15 by limiting the slide rail 22 and the slider 23, thereby facilitating the processing of the profile held by the tooling fixture 9. The debris generated during the processing of the profile will fall onto the outer surface of the baffle frame 13 and slide down the outer surface of the baffle frame 13 into the hollow groove 14, and finally be discharged from the engraving and milling machine; In addition, debris falling to the intersection of the vertical and horizontal parts of the base 1 can be discharged to the hollow groove 14 through the guide plate 10, thus avoiding the accumulation of debris at the intersection of the vertical and horizontal parts of the base 1.

[0030] Example 2: To solve the problem in Example 1 where debris easily adheres to the baffle frame 13 due to adhesion, the following technical solution is provided: a vibration-type debris removal mechanism is installed on the protective transmission mechanism.

[0031] In a preferred embodiment of the invention, the vibration-type impurity removal mechanism includes a limiting groove 17 provided on the lower surface of the limiting block 16, and the upper end of the limiting shaft 18 extends movably into the inside of the limiting groove 17. The lower end of the limiting shaft 18 is fixedly connected to the corresponding support block 19, and a spring 20 nested on the outside of the corresponding limiting shaft 18 is provided between the support block 19 and the limiting block 16.

[0032] In the above technical solution, by setting the limiting shaft 18, the limiting groove 17 and the spring 20, not only is rigid impact of the baffle 13 avoided, but the baffle 13 is also helped to vibrate up and down, which helps to shake off the debris adhering to it.

[0033] In a preferred embodiment of the invention, paddles 25 are evenly distributed on the inner side of the baffle frame 13, and spring pieces 24 are distributed on the outer sides of the slider 23 and the nut sleeve 27, with the spring pieces 24 connected between adjacent paddles 25.

[0034] In the above technical solution, the movement of the slider 23 and the nut sleeve 27 allows the spring piece 24 to slide on the paddle 25, which helps to move the stop frame 13 with the paddle 25 upward by the squeezing force, and then the stop frame 13 can automatically fall down by gravity.

[0035] In a preferred embodiment of the invention, the cross sections of the spring 24 and the paddle 25 are both isosceles triangles, which facilitates the reciprocating movement of the stop frame 13 by the spring 24 pressing the paddle 25 when the slider 23 and the nut sleeve 27 move.

[0036] In the above technical solution, by setting both the spring piece 24 and the paddle piece 25 into a structure with an isosceles triangle cross section, the baffle frame 13 can be driven to vibrate up and down regardless of whether the slider 23 and the nut sleeve 27 move forward or backward.

[0037] When using, according to Figures 3-10When the slider 23 moves on the slide rail 22 and the nut sleeve 27 moves on the lead screw shaft 26, the spring piece 24 can move relative to the paddle piece 25, and then the stop frame 13 can be moved upward by the squeezing force. After that, the stop frame 13 falls back by its own weight. During the fall, it can be supported by the spring 20 to avoid the stop frame 13 from having a rigid impact. During the above process, the baffle frame 13 can vibrate, thereby shaking off the debris adhering to it and preventing other debris from accumulating on the baffle frame 13 due to the adhering debris.

[0038] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
