[0001] The utility model relates to the field of profile cutting equipment, in particular to a single-head compound angle saw for cutting profiles with multiple modeling angles. Background Art

[0002] Compound angle saws are mainly used for cutting door and window profiles, and are often used in door and window profile processing. Existing door and window profiles are mainly cut at regular 45°, which is mainly achieved by double-head compound angle saws. With the emergence of sun rooms and the existence of various cavities, door and window profiles need to be cut at various special angles due to the needs of various shapes. Although the existing double-head compound angle saws can also achieve cutting at any angle, the existence of double-head saws cannot have special benefits for such special angles, such as improving cutting efficiency or reducing equipment costs. On the contrary, when this double-head saw cuts at such a special angle, the two will interfere with the angle position change of the sawing head, resulting in inconvenience in moving the sawing head. Therefore, it is necessary to improve this sawing device that does not have a particularly prominent effect and increases the equipment cost, so that it can be suitable for cutting at angles required by various shapes and can reduce equipment costs. Equipment that is flexible and convenient to move. Utility Model Content

[0018] like Figure 1-3 As shown, a single-head compound angle saw for cutting profiles with multiple shaping angles comprises two first guide rails 1 arranged in parallel and spaced apart in the front-rear direction, a gantry 2 is slidably arranged between the two first guide rails 1, the gantry 2 is connected to a first driving unit 4, and the gantry 2 is driven to move along the first guide rails 1. A second guide rail 3 is arranged on the crossbeam of the gantry 2 along its length direction. In order to improve stability, three second guide rails 3 are arranged, one on the upper surface of the crossbeam and two on the left side. A slide 5 is slidably arranged on the second guide rail 3, and the slide 5 is slidably arranged on the three second guide rails 3 at the same time. The slide 5 is connected to a second driving unit 6 arranged on the crossbeam, and the second driving unit 6 drives the slide 5 to slide along the second guide rail 3.

[0019] A first slide groove 7 is vertically provided on the slide seat 5. A vertical beam 8 is slidably provided in the first slide groove 7. The vertical beam 8 is substantially a hollow rectangular column. The vertical beam 8 is connected to a third driving unit provided thereon. The third driving unit drives the vertical beam 8 to move up and down. A cutting saw head 10 is provided on the vertical beam 8 through a rotating worktable 9. The rotating worktable 9 is integrally provided inside the vertical beam 8. Only the cutting saw head 10 is exposed outside the vertical beam 8 to cut the profile. A mounting platform 11 is also provided between the two first guide rails 1. A third guide rail 12 is provided on the upper surface of the mounting platform 11. The third guide rail 12 is provided parallel to the first guide rail 1. A support platform is slidably provided on the third guide rail 12. A clamping mechanism 14 is also provided on the mounting platform 11. The clamping mechanism 14 is higher than the support platform and is located above the support platform. When the cutting saw head 10 cuts the profile, the clamping mechanism 14 clamps the profile to prevent the profile from moving.

[0020] Furthermore, two third guide rails 12 are provided, and the two third guide rails 12 are arranged in parallel and at intervals. The support platform includes multiple independent support plates 13, and the multiple support plates 13 are arranged at intervals along the length direction of the third guide rail 12. Each support plate 13 is provided with a locking member 16. In the present embodiment, the locking member 16 adopts a locking bolt, and each support plate 13 is provided with a threaded hole corresponding to the sliding third guide rail 12. The center axis of the threaded hole is perpendicular to the third guide rail 12, and the locking bolt realizes the locking and release of each support plate 13 by screwing it into the depth of the threaded hole. The support platform is arranged in the form of multiple support plates 13, and the distance between each support plate 13 can be adjusted as needed, thereby increasing the support length of the support platform and expanding the range of the support platform for supporting profiles of different lengths.

[0021] Furthermore, in order to prevent the profile from rotating at a large angle on the support plate 13 , both ends of each support plate 13 are provided with limit baffles 23 , and the limit baffles 23 are arranged perpendicular to the support plate 13 .

[0022] Further, the mounting table 11 is provided with a mounting groove 22 between the two corresponding third guide rails 12, and a fourth guide rail 21 is provided in the mounting groove 22, and the fourth guide rail 21 is arranged parallel to the third guide rail 12, and a T-shaped sliding plate 15 is slidably provided on the fourth guide rail 21, and the T-shaped sliding plate 15 is connected to a fourth driving unit arranged in the mounting groove 22, and the fourth driving unit drives the T-shaped sliding plate 15 to slide along the fourth guide rail 21, and a second sliding groove 17 is provided in the vertical surface of the T-shaped sliding plate 15, and a positioning plate 18 is slidably provided in the second sliding groove 17 The positioning plate 18 is vertically arranged (i.e., arranged perpendicular to the supporting plate 13). The positioning plate 18 is connected to the fifth driving unit 19 arranged thereon. The fifth driving unit 19 drives the positioning plate 18 to slide up and down along the second slide groove 17. When positioning the profile, the profile is placed above the supporting plate 13, and then the clamping mechanism 14 presses the profile. At the same time, the positioning plate 18 slides upward and abuts against the end of the profile. The positioning plate 18 cooperates with the clamping mechanism 14 to clamp the profile in place, and then the cutting saw head 10 can perform angle cutting on the profile.

[0023] Furthermore, the specific structure of the above-mentioned clamping mechanism 14 includes an L-shaped fixing frame 1403, the upper end of the L-shaped fixing frame 1403 is arranged higher than the supporting plate 13, and a telescopic cylinder 1402 is arranged on the L-shaped fixing frame 1403. The telescopic cylinder 1402 here can be an electric cylinder, a pneumatic cylinder or an oil cylinder, but considering the simplicity of the structure, an electric cylinder can be preferably used. The piston rod end of the telescopic cylinder 1402 is connected to a clamping block 1401, and the clamping block 1401 is located above the supporting platform. The telescopic cylinder 1402 drives the clamping block 1401 to rise and fall to clamp or release the profile.

[0024] Furthermore, two racks 20 are correspondingly provided near the two first guide rails 1, and each rack 20 is arranged along the length direction of the first guide rail 1. Two first drive units 4 are provided, and the two first drive units 4 are correspondingly arranged at the two columns of the gantry 2. Each first drive unit 4 includes a first motor, a first reducer and a first gear. The first motor and the first reducer are transmission-connected and arranged on the column of the gantry 2. The first gear is connected to the output shaft of the first reducer and meshes with the rack 20. For this kind of drive with a longer horizontal stroke, the use of a gear rack 20 is more convenient and the structure is relatively light.

[0025] Furthermore, the second drive unit 6, the third drive unit, the fourth drive unit and the fifth drive unit 19 have the same structure, which are driven by a motor screw and nut. The moving stroke in the above driving process is not long, and the cutting position adjustment is mainly performed here, which requires high precision, and the use of a screw and nut can better meet the requirements.

[0026] The above-mentioned specific implementation manner cannot be used as a limitation on the protection scope of the present utility model. For those skilled in the art, any replacement, improvement or change made to the implementation manner of the present utility model falls within the protection scope of the present utility model.

[0027] The matters not described in detail in the present invention are all known technologies to those skilled in the art.
