Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically to a novel angle saw. Background Technology

[0002] In industrial production, aluminum doors and windows, aluminum curtain walls, and industrial aluminum profiles are typically cut using sawing equipment. Different processing requirements often correspond to different cutting angles, necessitating that the saw possess multiple cutting angle capabilities. Consequently, saws capable of cutting at multiple angles have emerged on the market and are widely used in the cutting of interior decoration building materials and door and window profiles.

[0003] For example, the applicant previously filed a utility model patent with authorization announcement number CN217530970U, entitled "A Digital Display Arbitrary Angle Saw." This saw can cut any angle from 0 to 180 degrees as needed, is easy to adjust, and has a wide range of applications. However, this angle saw has a problem: during use, a hand-cranked turntable must first be rotated, which drives the rotating base to rotate via a worm gear and transmission wheel. After the saw turntable rotates to the appropriate angle, a lifting cylinder is needed to push the saw assembly upwards. Only after the saw assembly is in place can the saw blade begin cutting the profile. Therefore, its entire cutting structure is relatively complex, and the operation process is cumbersome, which is not conducive to reducing equipment manufacturing costs or improving cutting efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new type of angle saw to solve the problems that the overall cutting structure of the existing cutting saw blade is relatively complex, the operation process is relatively cumbersome, and it is not conducive to reducing the cost of equipment manufacturing and improving cutting efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This application provides a novel angle saw, including a frame, characterized in that it further includes:

[0007] The cutting saw blade has a cutting groove formed on the upper end face of the frame, and the cutting saw blade is installed in the cutting groove and can reciprocate along the cutting groove.

[0008] The drive motor is connected to the cutting saw blade;

[0009] The transmission device is slidably connected to the frame along the sliding direction parallel to the cutting blade, and the drive motor is fixedly mounted on the transmission device;

[0010] The motor is connected to the transmission device;

[0011] The corner support plate includes a semi-circular rotating disk and a mounting bracket. The rotating disk is formed with an arc-shaped sliding groove, and the upper end surface of the frame is formed with a moving groove. An inner ruler pointer is provided on the upper end surface of the rotating disk. The inner ruler pointer is fixedly connected to a slider installed at the bottom of the rotating disk through a connecting shaft. The slider is slidably installed on the moving groove. The connecting shaft is located in the sliding groove, and the rotating disk can slide relative to the connecting shaft. The bottom end of the mounting bracket is fixedly installed on the rotating disk.

[0012] A clamping device is fixedly installed at the top of the mounting bracket, and the clamping device is used to clamp the profile.

[0013] Furthermore, the angle saw also includes a saw blade guard, which is mounted on the output shaft of the drive motor and is rotatably connected to the output shaft of the drive motor. The saw blade guard is formed with a receiving groove, and the lower half of the cutting saw blade extends into the receiving groove.

[0014] Furthermore, the bottom end of the saw blade protective cover is also connected to a sawdust collection groove, which is connected to the bottom end of the receiving groove.

[0015] Furthermore, the clamping device includes a connecting frame, a cylinder, and a pressure block. One end of the connecting frame is mounted on the mounting bracket, the cylinder is vertically fixedly mounted on the other end of the connecting frame, and the pressure block is mounted on the piston rod of the cylinder. The pressure block is used to clamp the profile placed on the frame.

[0016] Furthermore, the connecting frame is mounted on the connecting frame by a clamping block, which can be adjusted in height relative to the connecting frame.

[0017] Furthermore, the clamping device is a pair, and the pair of clamping devices is installed on the top of the mounting bracket.

[0018] Furthermore, the transmission device includes a slide plate, the motor and the drive motor are respectively fixedly mounted on the slide plate, the bottom end of the frame is provided with a slide rail in a direction parallel to the movement of the cutting saw blade, and a rack is also provided on one side of the slide rail parallel to it. The bottom end of the slide plate is slidably connected to the slide rail through a slider, and the output end of the motor meshes with the rack through a gear.

[0019] Furthermore, a protective cover is installed on the other end of the movable slot relative to the corner rest plate.

[0020] Furthermore, a scale is installed on the upper surface of the frame, which is parallel to the moving groove.

[0021] Furthermore, the clamping device is respectively provided on the frame on both sides of the cutting saw blade.

[0022] The beneficial effects of this utility model are as follows:

[0023] 1. By adopting the above-mentioned new angle saw, the angle plate is used to position the profile to be cut at the cutting angle. Since the angle plate can be adjusted to any angle between 0-180° relative to the frame through the rotating disk at its bottom, it can achieve cutting of the profile at any angle between 0-180°. At the same time, the profile is pressed by the clamping device, and the motor-driven transmission device drives the cutting saw blade to move along the cutting groove on the frame. The cutting saw blade completes the cutting action of the profile. The whole cutting structure is simple, which is conducive to reducing the equipment manufacturing cost. The cutting process is simple and fast, which can improve the cutting efficiency.

[0024] 2. By setting the cutting saw blade to be movable relative to the cutting groove, when cutting profiles with small cross-sections, the cutting saw blade can be moved directly to the vicinity of the profile through the transmission device before the cutting saw blade is started to cut directly, avoiding the need for the cutting saw blade to move a certain distance before contacting the profile, thus improving cutting efficiency.

[0025] 3. By installing a saw blade guard on the lower half of the cutting saw blade, the saw blade guard can move synchronously with the cutting saw blade. In this way, the waste generated by the cutting saw blade can enter the saw blade guard and be collected in real time. Attached Figure Description

Detailed Implementation

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0038] See appendix Figure 1 To be continued Figure 2 As shown, this embodiment provides a novel angle saw 10, including a frame 10, a cutting saw blade 500, a drive motor 700, a transmission device 600, an angle support plate 300, and a clamping device 400.

[0039] See attached document Figure 1 and attached Figure 2 As shown, a long strip-shaped cutting groove 101 is formed on the upper end surface of the frame 10. The cutting groove 101 is arranged along the length direction of the frame 10. For example, the cutting groove 101 can extend from one end of the frame 10 to the other end. The cutting groove 101 can be formed at the center position of the frame 10. It is understood that in other embodiments, the cutting groove 101 can also be formed at other positions on the upper end surface of the frame 10, without limitation.

[0040] Continue to refer to the appendix Figure 1 and attached Figure 2As shown, the cutting saw blade 500 is installed at one end of the cutting groove 101. The cutting saw blade 500 can reciprocate along the cutting groove 101, that is, the cutting saw blade 500 can move from one end of the cutting groove 101 to the other end. A protective cover 200 is fixedly installed on the cutting groove 101 at the other end of the cutting saw blade 500. The protective cover 200 is provided to prevent the cutting saw blade 500 from accidentally causing injury to personnel during cutting.

[0041] See attached document Figure 1 Appendix Figure 4 Appendix Figure 5 and appendix Figure 9 As shown, the cutting saw blade 500 is driven to move by a transmission device 600 and a motor 603 located at the bottom of the frame 10. The transmission device 600 includes a slide plate 601, and the motor 603 and drive motor 700 are respectively fixedly installed on the top of the slide plate 601. A slide rail 602 is provided at the bottom of the frame 10 along the direction parallel to the movement of the cutting saw blade 500. A rack 605 is also provided on the inner side of the slide rail 602 and is parallel to it. The bottom of the slide plate 601 is slidably connected to the slide rail 602 by a slider. The output end of the motor 603 meshes with the rack 605 through a gear 604.

[0042] When the servo motor is activated, motor 603 drives gear 604 to rotate. Gear 604, in a rotating state, meshes with rack 605. Since rack 605 is fixedly mounted at the bottom of frame 10, gear 604 moves along rack 605, thereby moving slide plate 601. Consequently, drive motor 700, fixedly mounted on slide plate 601, also synchronously drives cutting saw blade 500 to move along cutting groove 101, thus cutting the profile placed on frame 10 (in this embodiment, drive motor 700 drives cutting saw blade 500 to rotate via transmission belt and transmission shaft 701). By setting cutting saw blade 500 to be movable relative to cutting groove 101, when cutting profiles with small cross-sections, cutting saw blade 500 can be moved directly to the vicinity of the profile via transmission device 600 before starting to cut, avoiding the need for cutting saw blade 500 to move a certain distance before contacting the profile, thus improving cutting efficiency.

[0043] See attached document Figure 2 Appendix Figure 3 Appendix Figure 4 Appendix Figure 5 and appendix Figure 8As shown, a saw blade guard 800 is installed below the cutting saw blade 500. The saw blade guard 800 is mounted on the output shaft of the drive motor 700, and the saw blade guard 800 and the output shaft of the drive motor 700 are rotatably connected. The saw blade guard 800 has a receiving groove 801 formed therein, and the lower half of the cutting saw blade 500 extends into the receiving groove 801. When the cutting saw blade 500 is rotating and cutting, the cutting saw blade 500 will not contact the groove wall of the receiving groove 801, and will not affect the cutting of the cutting saw blade 500. The saw blade guard 800 is designed so that the waste generated by the cutting saw blade 500 when cutting profiles can automatically fall into the receiving groove 801 of the saw blade guard 800 for collection.

[0044] In some embodiments, in order to better collect and clean the waste generated during the cutting of the saw blade 500, a sawdust collection trough is also connected to the bottom end of the saw blade guard 800. The sawdust collection trough is connected to the bottom end of the receiving trough 801. The sawdust collection trough can be installed at the bottom end of the frame 10 at a downward inclination. In this way, the waste in the saw blade guard 800 can fall into the sawdust collection trough and automatically slide down along the inclination direction of the sawdust collection trough for centralized collection.

[0045] See attached document Figure 1 Appendix Figure 6 and attached Figure 7 As shown, in this embodiment, the corner support plate 300 is used for supporting and positioning the profile to be cut. That is, one side of the profile to be cut is placed against the corner support plate 300 and simultaneously pressed by the pressing device 400 installed above the corner support plate 300.

[0046] Specifically, the corner support plate 300 includes a semi-circular rotating disk 301 and a mounting bracket 302. The rotating disk 301 is formed with an arc-shaped groove 303, which is a 180° arc-shaped slotted structure. The upper end surface of the frame 10 is formed with a moving groove 102. An inner ruler pointer 304 is provided on the upper end surface of the rotating disk 301. The inner ruler pointer 304 is fixedly connected to a slider 305 installed at the bottom of the rotating disk 301 through a connecting shaft. The slider 305 is slidably installed on the moving groove 102. The connecting shaft is located in the groove 303, and the rotating disk 301 can slide relative to the connecting shaft. The bottom end of the mounting bracket 302 is fixedly installed on the rotating disk 301.

[0047] See attached document Figure 7As shown, the rotating disk 301 can rotate along the connecting shaft via the arc-shaped sliding groove 303 on it. That is, the rotating disk 301 can rotate relative to the upper end surface of the frame 10, realizing the angle adjustment of the corner plate 300° to 180°, thereby realizing the conversion of the cutting angle of the profile from 0° to 180°. At the same time, since the slider 305 at the bottom end of the rotating disk 301 can move along the moving groove 102 on the frame 10, the rotating disk 301 can move relative to the frame 10 to adapt to the cutting of profiles with different widths.

[0048] See attached document Figure 1 and attached Figure 6 As shown, the clamping device 400 includes a connecting frame 401, a cylinder 402, and a clamping block 403. One end of the connecting frame 401 is mounted on the mounting bracket 302, and the cylinder 402 is vertically fixedly mounted on the other end of the connecting frame 401. The clamping block 403 is mounted on the piston rod of the cylinder 402, with one end of the piston rod facing downwards. The clamping block 403 is used to clamp the profile placed on the frame 10. That is, when it is necessary to clamp the lower profile, the cylinder 402 pushes the piston rod downwards, and the extended piston rod in turn drives the clamping block 403 to move downwards. The clamping block 403 presses against the upper end face of the profile, thereby clamping the profile and preventing it from shaking during cutting. (See attached diagram.) Figure 6 As shown, in some embodiments, the connecting frame 401 is mounted on the connecting frame 401 via a clamping block 404, which is adjustable in height relative to the connecting frame 401. In some embodiments, the clamping device 400 may be a pair to improve the clamping effect on the profile. Furthermore, in some embodiments, clamping devices 400 are symmetrically arranged on opposite sides of the cutting saw blade 500 on the frame 10 to ensure better clamping of the profile.

[0049] See attached document Figure 1 and attached Figure 7 As shown, in order to intuitively know the cutting dimensions of the profile, a scale 103 is installed on the upper end face of the frame 10, which is parallel to the moving groove 102.

[0050] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
