The moving direction of the movable part of the horizontal axis 206 is parallel to the length direction of the reserved gap 103, and the movable part is provided with a spindle motor 214 whose axis of the output shaft is perpendicular to the length direction of the reserved gap 103, and the output shaft of the spindle motor 214 extends toward the second operating table 102 On the side where the output shaft is located, a cutting tool 215 is arranged on the output shaft, and the cutting tool 215 is arranged opposite to the reserved gap 103; the first clamping device 300 includes a first pressing plate 301 and a second pressing plate 307, both of which are parallel to the length direction of the reserved gap 103. The first pressing plate 301 is arranged directly above the first operating table 101, and a first driving device 302 is provided to control the first pressing plate 301 to move up and down. The second pressing plate 307 is arranged directly above the second operating table 102, and a second driving device is provided to control 308 The second pressure plate 307 moves up and down; the second clamping device 400 includes a third operating table 405 arranged on the second mounting table 105, and the third operating table 405 can move perpendicularly to the length direction of the reserved gap 103 and close to or away from the side where the spindle motor 214 is located. The third operating table 405 is provided with a limit block 406 whose length direction is perpendicular to the length direction of the reserved gap 103, and a three-axis cylinder 407 facing the limit block 406, and a third pressure block 408 is arranged on the telescopic axis of the three-axis cylinder 407.

[0029] When used for sawing, the profile is placed on the frame 100, supported by the first operating table 101 and the second operating table 102 below the profile, and then the first pressing plate 301 is controlled 302 by the first driving device to move downward, and the second pressing plate 307 is controlled 308 by the second driving device to move downward, so as to firmly fix the profile. At this time, the cutting tool 215 should be below the first operating table 101 and the second operating table 102. First, the spindle motor 214 drives the tool to rotate at a high speed, and then the lifting device 201 can drive the spindle motor 214 carrying the tool to move upward, so that the tool extends upward from the reserved gap 103 and cuts off the profile.

[0030] It is worth noting that in order to be able to cut a large number of profiles at one time, a suitable number of profiles can be laid out flat on the first operating table 101 and the second operating table 102 and fixed by the first clamping device 300, and then the horizontal axis 206 and the driving spindle motor 214 drive the high-speed running tool to move from one end of the reserved gap 103 to the other end, so that a large number of profiles can be cut with only one clamping, greatly improving the processing efficiency.

[0031] If the profile needs to be beveled, it is only necessary to adjust the angle before the first clamping device 300 fixes the profile.

[0032] Among them, if there is no need for cutting or beveling of profiles, or if there is a greater demand for profile grooving, such as Figure 2 As shown, the second mounting table 105 can be removed, and a suitable cutting tool 215 (a saw blade of suitable thickness or a T-shaped knife) can be replaced for the spindle motor 214. Then, the profile (aluminum bar) that needs to be slotted can be set on the third operating table 405 and placed between the limit block 406 and the three-axis cylinder 407. After adjusting the placement position, the three-axis cylinder 407 is used to push the third pressure block 408 to cooperate with the limit block 406 to fix the profile. The lifting device 201 controls the height of the cutting tool 215, and moves the cutting tool 215 to one end of the length direction of the reserved gap 103 through the horizontal axis 206. Then, the third operating table 405 is moved toward the direction of the drive motor and moved to the appropriate position. The horizontal axis 206 drives the high-speed rotating cutting tool 215 to move along the length direction of the reserved gap 103 and completes the slotting process.

[0033] like Figure 3 As shown, the lifting device 201 includes a first mounting plate 202 disposed directly above the first mounting platform 104, a worm gear device 203 for controlling the lifting of the first mounting plate 202 is disposed between the first mounting plate 202 and the first mounting platform 104, and a lifting motor 204 is disposed to drive the worm gear device 203, first guide rods 205 that are slidably matched with the first mounting platform 104 are vertically disposed on both sides of the worm gear device 203, and the top of the first guide rod 205 is fixedly connected to the first mounting plate 202, and the first mounting plate 202 is used to set a horizontal axis 206. In order to achieve the precise requirements of lifting control, the lifting motor 204 is preferably a private service drive motor.

[0034] Among them, the horizontal axis 206 includes a mounting seat 207 fixedly connected to the first mounting plate 202, and a first slide rail 208 is arranged on the mounting seat 207, and a length direction is parallel to the length direction of the reserved gap 103. A second mounting plate 209 is arranged above the first slide rail 208, and the second mounting plate 209 is slidably connected to the first slide rail 208 through a first slider 210 to form a movable part. A first screw rod 211 is arranged on the mounting seat 207 and is rotatably connected thereto. The first screw rod 211 is connected to the second mounting plate 209 through a first nut 212. A first motor 213 is also arranged on the mounting seat 207 and is transmission-connected to the first screw rod 211. The spindle motor 214 is arranged on the second mounting plate 209. The first motor 213 is a servo-controlled motor, and the accuracy of movement control is achieved through the cooperation of the servo motor and the screw rod. At the same time, it has good stability in use and faster response efficiency.

[0035] like Figure 1 and Figure 2 As shown, the first driving device includes two first vertical plates 303 provided on the first operating table 101, the first vertical plates 303 are provided at both ends of the length direction of the reserved gap 103, the top of the first vertical plates 303 is fixedly provided with a first horizontal plate 304 which simultaneously connects the two first vertical plates 303, the first horizontal plate 304 is vertically provided with a second guide rod 305 which is slidably matched therewith, the lower end of the second guide rod 305 is fixedly connected to the first pressing plate 301, the first horizontal plate 304 is also provided with a first cylinder 306, the output shaft of the first cylinder 306 is vertically extended downward and connected to the first pressing plate 301, and the up and down movement of the first pressing plate 301 is controlled by the first cylinder 306 The second driving device includes two second vertical plates 309 provided on the second operating table 102, and the second vertical plates 309 are provided at both ends of the length direction of the reserved gap 103. A second horizontal plate 310 is fixedly provided on the top of the second vertical plates 309 and connects the two second vertical plates 309 at the same time. A third guide rod 311 is vertically provided on the second horizontal plate 310 and slidably cooperates with it. The lower end of the third guide rod 311 is fixedly connected to the second pressing plate 307. A second cylinder 312 is also provided on the second horizontal plate 310. The output shaft of the second cylinder 312 extends vertically downward and is connected to the second pressing plate 307. The up and down movement of the second pressing plate 307 is controlled by the second cylinder 312.

[0036] like Figure 4As shown, in order to achieve the precise demand for movement control of the third operating platform 405, a second slide rail 401 is provided on the second mounting platform 105, and the third operating platform 405 is slidably connected to the second slide rail 401 through a second slider 402. The second mounting platform 105 is also provided with a second screw rod 403 rotatably connected thereto, and the length direction of the second screw rod 403 is parallel to the length direction of the second slide rail 401. The second screw rod 403 is connected to the second mounting platform 105 through a second nut. The second mounting platform 105 is also provided with a second motor 404 that is transmission-connected to the second screw rod 403, wherein the second motor 404 is preferably a servo-controlled motor.

[0037] Regarding the positioning problem during the profile slotting process, it should be noted that the profile slotting position needs to be able to be moved to the position directly below the reserved gap 103 (on the horizontal movement path of the cutting tool 215) by controlling the movement of the third operating table 405. In order to facilitate the positioning of the slotting position, a positioning block 409 is also provided on the third operating table 405. The length direction of the positioning block 409 is perpendicular to the length direction of the limit block 406. The positioning block 409 is provided on the side of the third operating table 405 close to the direction of the spindle motor 214. During processing, the positioning block 409 can be used to position the end of the profile to achieve the positioning of the profile slotting position. Figure 4 At this time, it should be noted that the third operating table 405 needs to be able to move to just below the reserved gap 103 so that the slotting position is on the horizontal movement path of the cutting tool 215, that is, the second slider 402 close to the spindle motor 214 cannot be flush with the side of the third operating table 405 close to the spindle motor 214, and space needs to be reserved for the third operating table 405 to move toward the spindle motor 214.

[0038] like Figure 5-6As shown, in order to improve the profile positioning efficiency during the beveling process and improve the convenience of operation, two T-slots 106 with upward openings are arranged on the second operating table 102, and the length direction of the T-slots 106 is parallel to the length direction of the reserved gap 103. A connecting column 107 is arranged in each T-slot 106, and the connecting column 107 includes a large end 108 that can be embedded and slid in the T-slot 106, and a guide column 109 extending upward is arranged on the large end 108, and a stud 110 is arranged at one end of the guide column 109 away from the large end 108, and a bushing 112 is passed through the guide column 109 on one of the connecting columns 107, and one end of the bushing 112 abuts against the upper surface of the second operating table 102 The other end of the connecting column 107 abuts against the nut 111 provided on the stud 110, and the nut 111 presses the bushing 112 downward to fix the bushing 112 to the second mounting platform 105. The second mounting platform 105 is provided with a stopper 113, one end of which is provided with an axial hole 114, which is rotatably connected to the bushing 112, and the other end of the stopper 113 is provided with a positioning groove 115 extending along the length direction, wherein the guide column 109 on another connecting column 107 is inserted into the positioning groove 115 and extends upward, and the stud 110 of the connecting column 107 is provided with a nut 111 to press the stopper 113 downward to fix the stopper 113 to the second mounting platform 105. When beveling, the stopper 113 can be used to position and support the profile to achieve rapid cutting angle positioning. When the bevel angle needs to be set, first set one end of the axial hole 114 of the stopper 113 through the connecting column 107, and then set the connecting column 107 at the direction end of the positioning groove 115 of the stopper 113. At this time, do not fix the stopper 113 first, and adjust the positioning angle by swinging the end of the positioning groove 115 of the stopper 113. After adjusting to the appropriate angle requirement, turn the nut 111 to press the stopper 113 downward through the nut 111 to fix the stopper 113 to the second mounting platform 105.

[0039] This method has two advantages: first, the angle adjustment is flexible and the operation is simple; second, it can be removed when the angle positioning is not needed, without affecting the processing of other functions.
