With the cooperation of the clamping device, firm clamping of the profile to be processed is achieved. On the premise that the saw blade 801 of the sawing component 8 can deflect, compound inclination angle processing of the end of the profile can be realized. On the one hand, the end inclination angle is guaranteed, and on the other hand, the inclination angle of the cross-section is guaranteed, making the use of this bench saw more flexible.

[0037] As Figure 1 shown, in this specific embodiment, the X-direction positioning member includes the first X-direction positioning plate 5 and the second X-direction positioning plate 4. The first X-direction positioning plate 5 and the second X-direction positioning plate 4 are symmetrically arranged on both sides of the cutting groove.

By providing the avoidance notch, sufficient space can be left for the angle adjustment of the saw blade 801 to avoid mis-cutting.

[0038] As Figure 1 and Figure 2 shown, in this specific embodiment, the Y-direction positioning component 6 further includes a Y-direction lead screw 602. The Y-direction lead screw 602 is rotatably arranged on the workbench 1 through a bracket. A Y-direction positioning plate 601 is arranged on the Y-direction lead screw 602.

By observing the digital display 7, the displacement amount of the Y-direction positioning plate 601 can be directly known, improving the adjustment accuracy and greatly reducing the manufacturing cost of this bench saw. In this specific embodiment, considering that the length of the profile to be processed is relatively long, in order to ensure its accurate positioning, two groups of Y-direction positioning components 6 are arranged along the length direction of the workbench 1.

[0039] As Figure 3 shown, in this specific embodiment, the rotation positioning component 3 further includes a rotation motor 301. The rotation motor 301 adopts a servo motor, which can improve the accuracy of controlling the rotation positioning plate 303. The rotation motor 301 is vertically downwardly installed on the workbench 1 through a support 302. The output shaft of the rotation motor 301 is connected to a rotating disk 304, and a rotation positioning plate 303 is vertically arranged on one side of the rotating disk 304.

[0040] As Figure 4As shown, in this specific embodiment, the clamping unit 2 further includes a mounting bracket. The mounting bracket has an L-shaped structure and includes a cross bar 201. The cross bar 201 is arranged parallel to the X-direction positioning member. To ensure reliable clamping of the profile to be processed, two downward pressing cylinders 203 are provided on the cross bar 201. The two downward pressing cylinders 203 are symmetrically arranged on both sides of the cutting groove. To correspond to the position after the profile is tilted, the cross bar 201 and the downward pressing cylinders 203 are connected by an adjustment plate 202. The adjustment plate 202 is rotatably arranged on the cross bar 201. Since the sizes of the profiles to be processed are different, to improve the flexibility of use of this clamping unit 2, an adjustment hole 204 is provided at the connecting end of the adjustment plate 202. A locking handle is arranged in the adjustment hole 204. The adjustment hole 204 is a straight groove hole, and the length direction of the adjustment hole 204 is the same as the length direction of the adjustment plate 202. By providing the adjustment hole 204, the position of the downward pressing cylinder 203 in the Y direction can be adjusted to adapt to profiles of various widths. The mounting end of the adjustment plate 202 is provided with a mounting hole, and the downward pressing cylinder 203 can move up and down in the mounting hole to adapt to profiles of different heights. Specifically, the mounting end of the adjustment plate 202 is provided with a mounting hole and a contraction groove. The contraction groove penetrates the mounting hole.

A locking bolt is arranged in the locking hole. When the locking bolt is tightened, the contraction groove is compressed, and the inner wall of the mounting hole closely adheres to the outer wall of the downward pressing cylinder 203. The end of the piston rod of the downward pressing cylinder 203 is connected with a pressing plate.

[0041] As Figure 5As shown, in this specific embodiment, the sawing assembly 8 may adopt the following specific structure: The sawing assembly 8 includes a support base 802, which is in an L-shaped structure. The support base 802 is movably arranged inside the workbench 1 along the X-axis of the panel saw, and the support base 802 is movably arranged on the bottom plate 803 along the Y-direction. A moving motor and a gear are vertically arranged downward on the bottom plate 803. The gear meshes with the rack at the bottom of the workbench 1 to realize the movement of the sawing assembly 8 along the X-axis of the panel saw; A swing arm 810 is arranged on the support base 802. The swing arm 810 can rotate around the X-axis of the panel saw through a pin shaft 808. Specifically, a motor is arranged on the swing arm 810. The motor is horizontally arranged and connected with a gear. An arc-shaped rack is arranged on the support base 802. The gear meshes with the rack, so that the swing arm 810 can swing in an arc, thereby adjusting the deflection angle of the saw blade 801; A connecting arm 806 is arranged through the swing arm 810, and the connecting arm 806 also passes through the support base 802. One end of the connecting arm 806 is provided with a saw blade 801, and the other end of the connecting arm 806 is provided with a sawing motor 805. The sawing motor 805 drives the saw blade 801 to rotate through a belt drive mechanism; When the profile to be processed is cut, the sawing assembly 8 needs to reciprocate along the workbench 1. In order to prevent the saw blade 801 from accidentally cutting the processed profile, the saw blade 801 needs to be lifted and lowered. The connecting arm 806 is connected to the swing arm 810 through a rotating shaft 809. The rotating shaft 809 is arranged along the Y-axis of the panel saw. A lifting cylinder 804 is inclinedly arranged on the swing arm. The piston rod of the lifting cylinder 804 is connected to the connecting arm 806. When the piston rod of the lifting cylinder 804 extends, the end of the connecting arm 806 where the sawing motor 805 is installed is lifted, and the end where the saw blade 801 is located descends into the workbench 1. At this time, the support base 802 returns to its position, which can avoid scratching the cut profile. Upper and lower limit blocks 807 are also arranged on the swing arm. The upper and lower limit blocks 807 are located on the upper and lower sides of the connecting arm 806, which can realize the hard limit of the swing of the connecting arm 806 and improve the use safety of this panel saw.

[0042] This specific embodiment further includes a control system, which is electrically connected to the sawing assembly 8, the rotary positioning assembly 3, and the clamping unit 2; A protective cover 9 is also movably arranged on the workbench 1. The protective cover 9 is connected to the sawing assembly 8 and can move with the movement of the saw blade 801.

[0043] The process of positioning the profile to be processed by this compound angle single-head cutting panel saw is as follows:

[0044] When no inclination angle is set at the end of the profile, rotate the rotary positioning plate 303 to one side so that it does not interfere with the profile to be processed. Determine the displacement distance of the Y-direction positioning plate 601 according to the distance between the width of the profile to be processed and the cutting processing reference. Hand-crank the Y-direction lead screw 602 until the Y-direction positioning plate 601 moves into place. Load the profile to be processed from the side of the Y-direction positioning assembly 6, and push the profile to be processed so that its side is in contact with the Y-direction positioning plate 601. Then, push the profile to be processed in the X direction so that its end is in contact with the X-positioning part, and control the action of the downward pressure cylinder 203 to tightly press on the upper surface of the profile to be processed.

[0045] When an inclination angle needs to be processed at the end of the profile, rotate the rotary positioning plate 303 to the set position and move the Y-direction positioning plate 601 to the set position. Load the profile to be processed from the side of the Y-direction positioning assembly 6, and rotate the profile to be processed so that its side is in contact with the surface of the rotary positioning plate 303, and its vertex angle is in contact with the Y-positioning plate or the X-positioning part. Control the action of the downward pressure cylinder 203 to tightly press on the upper surface of the profile to be processed. It should be noted that there are two combinations of positioning. One is the rotary positioning assembly 3 and the Y-direction positioning assembly 6. In this case, the X-positioning part does not participate in positioning, and the profile to be processed is far from the X-positioning part. The other is that the rotary positioning assembly 3 and the X-positioning part participate in positioning. In this case, the Y-direction positioning assembly 6 does not participate in positioning. If the profile to be processed is relatively long, then the Y-direction positioning plate 601 needs to be adjusted to a position far from the workbench 1 to avoid interference. Which positioning combination to use needs to be determined according to the inclination angle of the profile end.

[0046] It can be seen from the above specific embodiments that the present utility model has the following beneficial effects:

[0047] 1. Through the cooperation of the rotary positioning assembly 3, the Y-direction positioning assembly 6 and the X-positioning part, the adjustment of the inclination angle of the profile to be processed can be realized. Under the action of the sawing assembly 8, the composite inclination angle processing of the profile end can be realized. On the one hand, the end inclination angle is ensured, and on the other hand, the inclination angle of the section is ensured, making the use of this platform saw more flexible.

[0048] 2. By setting the avoidance notch, enough space can be left for the angle adjustment of the saw blade 801 to avoid mis-cutting. Through the cooperation of the digital display 7 and the displacement sensor, the moving distance of the Y-direction positioning plate 601 can be accurately known, ensuring the accurate adjustment of the position of the profile to be processed.

[0049] 3. By adopting the servo motor, the rotation angle of the rotary positioning plate 303 can be accurately controlled, realizing the accurate adjustment of the inclination angle of the profile to be processed.

[0050] 4. By setting two downward pressure cylinders 203, the stable clamping of the profile to be processed can be realized, preventing deviation and affecting the processing accuracy.

[0051] 5. By setting the adjusting plate 202 to be able to correspond to the position of the profile to be processed after being set obliquely, reliable clamping is ensured;

[0052] 6. By setting the adjusting hole 204, the position of the downward pressing cylinder 203 in the Y direction can be adjusted to adapt to profiles of various widths;

[0053] 7. By setting the downward pressing cylinder 203 to be movable up and down, it can be adjusted according to the height of the profile to be processed to adapt to profiles of various heights;

[0054] 8. By setting the connecting arm 806 to be swingable, the lifting of the saw blade 801 can be realized, and the saw blade 801 can be prevented from damaging the cut profile when the support seat 802 returns to its original position.

[0055] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention.
