DETAILED DESCRIPTION

[0028] The following will be described in combination with the drawings Figures 1-2 The present application will be further described in detail.

[0029] The embodiment of the present application discloses a clamp for cutting aluminum alloy window frame. Referring to Figures 1-2 , the clamp for cutting aluminum alloy window frame includes an operation table 1, a positioning baffle 2, a pressing plate 3, a lower pressing block 4, a driving mechanism 5 and a pressing mechanism 6, and the top of the operation table 1 is provided with a cutting saw blade 8 driven by a motor 7.

[0030] The positioning baffle 2 is fixedly installed on the operation table 1 by the locking bolt 21. Specifically, an arc-shaped through slot 22 is formed in the positioning baffle 2, the locking bolt 21 is arranged in the arc-shaped through slot 22, and the locking bolt 21 is threadedly connected to the operation table 1 in the vertical direction. When the locking bolt 21 is tightened, the positioning baffle 2 is fixedly connected to the operation table 1. A sliding groove 11 is formed in the upper surface of the operation table 1 in a direction parallel to the plane on which the cutting saw blade 8 is arranged. A fixed rod 31 is arranged in the vertical direction on the abutting plate 3 and is rotatably connected to the abutting plate 3 about the axis of the fixed rod 31. The fixed rod 31 is arranged in the sliding groove 11 in the vertical direction and can slide in the extension direction of the sliding groove 11. The positioning baffle 2 is located on the movement track of the abutting plate 3. The driving mechanism 5 is arranged on the operation table 1 and is configured to drive the abutting plate 3 to move towards or away from the positioning baffle 2. The pressing block 4 is connected to the positioning baffle 2, and the pressing mechanism 6 is arranged on the positioning baffle 2 and is configured to drive the pressing block 4 to move in the vertical direction.

[0031] When the aluminum alloy window frame is cut, the window frame profile is placed on the operation table 1 and is abutted against the positioning baffle 2. The abutting plate 3 is driven to slide along the extension direction of the sliding groove 11 on the operation table 1 by the driving mechanism 5. The abutting plate 3 gradually approaches the positioning baffle 2 and presses the window frame profile against the positioning baffle 2, thereby limiting the left-right swing of the aluminum alloy window frame during cutting. At the same time, the pressing block 4 is driven to move downward in the vertical direction by the pressing mechanism 6, and the window frame profile is pressed against the operation table 1, thereby ensuring that the window frame profile cannot be pried upward or downward during cutting. Finally, the cutting saw blade 8 is driven to rotate by the motor 7, and the cutting of the window frame profile is realized. Through the cooperation of the driving mechanism 5 and the pressing mechanism 6, the aluminum alloy window frame is quickly and stably clamped, and the problems of left-right swing and upward-downward prying of the aluminum alloy window frame during cutting are improved, thereby improving the machining precision and quality.

[0032] The arc-shaped through slot 22 on the positioning baffle 2 cooperates with the locking bolt 21, so that when the locking bolt 21 is loosened, the positioning baffle 2 can rotate about the axis of the locking bolt 21, thereby adjusting the angle of the positioning baffle 2 relative to the saw blade. The fixed rod 31 is rotatably connected to the abutting plate 3 about the axis of the fixed rod 31, so that the angle of the abutting plate 3 relative to the saw blade can be adjusted, thereby enabling the window frame profile to be cut at different angles, and improving the applicability of the clamp.

[0033] The driving mechanism 5 comprises a screw rod 51 and a locking block 52. The screw rod 51 is rotatably connected to the fixed rod 31 along its own axis, and the length direction of the screw rod 51 is the same as the extending direction of the sliding groove 11. A rotating handle 511 is welded to the end of the screw rod 51 away from the fixed rod 31. The locking block 52 is rotatably connected to the operating table 1 through a first rotating rod 521, and the axis of the first rotating rod 521 is perpendicular to the axis of the screw rod 51 and parallel to the upper surface of the operating table 1. An external thread 522 is formed in the bottom of the locking block 52, and the external thread 522 in the bottom of the locking block 52 is threadedly connected with the screw rod 51 when the locking block 52 is in a horizontal state.

[0034] When the window frame profile to be cut is clamped, the external thread 522 in the bottom of the locking block 52 is threadedly connected with the screw rod 51 by rotating the locking block 52, and then the rotating handle 511 is rotated to drive the screw rod 51 to rotate, so that the fixed rod 31 drives the pressing plate 3 to move towards the positioning baffle 2, until the profile is tightly pressed on the positioning baffle 2, and the clamping and fixing of the window frame profile to be cut in the horizontal direction is realized. When the pressing plate 3 needs to be moved for a long distance, the locking block 52 is only rotated upwards to make the locking block 52 not threadedly connected with the screw rod 51, and then the screw rod 51 is directly driven to move along its own length direction, which is convenient to use.

[0035] With reference to Figure 2 The pressing mechanism 6 comprises a mounting seat 61, a supporting rod 62, a first connecting rod 63, a second connecting rod 64, a sliding block 65 and a power assembly. The mounting seat 61 is fixedly installed on the positioning baffle 2 by bolts, the supporting rod 62 is welded to the mounting seat 61 along the extending direction of the screw rod 51, and the sliding block 65 is slidably sleeved on the peripheral wall of the supporting rod 62. One end of the first connecting rod 63 is rotatably connected to the mounting seat 61, and the other end of the first connecting rod 63 is rotatably connected to the pressing plate 4. One end of the second connecting rod 64 is rotatably connected to the pressing plate 4, and the other end of the second connecting rod 64 is rotatably connected to the sliding block 65. The power assembly is used to drive the sliding block 65 to move.

[0036] When the workpiece to be cut is preliminarily clamped and fixed by the positioning baffle 2 and the pressing plate 3, the sliding block 65 is driven by the power assembly to move towards the mounting seat 61, so that the first connecting rod 63 and the second connecting rod 64 tend to be folded and overlapped, so that the pressing plate 4 moves downward, and then the pressing plate 4 is pressed on the workpiece to be cut, so as to limit the prying of the workpiece to be cut in the vertical direction.

[0037] Further, the lower pressing block 4 is vertically screwed with a lower pressing rod 41, and the bottom of the lower pressing rod 41 is provided with a pressure pad 42. In use, the lower pressing rod 41 replaces the lower pressing block 4 to press the workpiece, and rotating the lower pressing rod 41 can adjust the pressing degree of the workpiece, so that the aluminum alloy window frame of different thicknesses can obtain appropriate pressing force, improving the application range and pressing accuracy of the clamp. The pressure pad 42 can disperse the pressure of the lower pressing block 4 on the aluminum alloy window frame, prevent local pressure from being too large to cause deformation or damage of the window frame, and ensure the stability and safety of the cutting process.

[0038] For example, the power assembly includes a third connecting rod 66, one end of the third connecting rod 66 is rotationally connected with the sliding block 65, and the other end of the third connecting rod 66 is rotationally connected with the top of the pressing plate 3. When the pressing plate 3 moves along the operation table 1, one end of the third connecting rod 66 moves with the pressing plate 3, and the other end drives the sliding block 65 to slide along the support rod 62. The movement of the sliding block 65 further causes the first connecting rod 63 and the second connecting rod 64 to cooperate to push the lower pressing block 4 to move downward along the vertical direction, realizing the pressing of the aluminum alloy window frame. This linkage design not only improves the stability and reliability of the pressing, but also simplifies the operation steps and improves the work efficiency.

[0039] The implementation principle of the aluminum alloy window frame cutting clamp in the embodiment of the application is as follows: in use, the positioning baffle 2 is rotated according to the angle required by the workpiece to be cut, and then the positioning baffle 2 is locked by the locking bolt 21. Then the workpiece to be cut is directly placed on the operation table 1 and close to the positioning baffle 2, then the lead screw 51 is pushed until the pressing plate 3 abuts against the workpiece, then the locking block 52 is rotated downward, so that the external thread 522 on the locking block 52 is screwed with the lead screw 51, then the lead screw 51 is rotated to drive the pressing plate 3 to abut against the workpiece until the workpiece is clamped, thereby realizing the horizontal positioning of the workpiece.

[0040] In the process of moving the pressing plate 3 close to the positioning baffle 2, one end of the third connecting rod 66 moves with the pressing plate 3, and the other end drives the sliding block 65 to slide along the support rod 62. The movement of the sliding block 65 towards the positioning baffle 2 causes the first connecting rod 63 and the second connecting rod 64 to tend to fold and overlap, so that the lower pressing block 4 moves downward, and then the pressure pad 42 at the bottom end of the lower pressing rod 41 on the lower pressing block 4 presses the workpiece to be cut, thereby realizing the vertical positioning of the workpiece, and improving the problem that the aluminum alloy window frame swings left and right and rocks up and down during the cutting process, affecting the machining precision and machining quality.
