[0017] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0018] like Figure 1-3 As shown, this utility model provides a technical solution: an adjustable angle positioning fixture for a corner cutting machine, including a base plate 1, a rotating plate 2 rotatably mounted on one corner of the top of the base plate 1 via a bearing, a rectangular groove 3 on one side of the rotating plate 2, a limiting slide groove 4 penetrating through the bottom of the rectangular groove 3, a limiting slider 5 slidably connected through the limiting slide groove 4, and a moving block 6 sliding in the bottom of the rectangular groove 3 via the limiting slider 5, thereby driving the limiting slider 5 to slide in the limiting slide groove 4, limiting the moving block 6, and ensuring that the limiting slider 5 will not deviate during the sliding process;

[0019] A movable block 6 is fixedly installed on the top of the limiting slider 5, and the movable block 6 slides close to the bottom of the rectangular groove 3. An electric push rod 7 is embedded and fixedly installed on one side of the bottom of the rectangular groove 3, and the telescopic end of the electric push rod 7 is fixedly connected to the movable block 6. Because of the electric push rod 7, the extension and retraction of the electric push rod 7 is controlled to pull the movable block 6 to slide inside the rectangular groove 3, thereby pulling the connecting strip 8 to rotate on the top of the movable block 6.

[0020] A connecting bar 8 is symmetrically mounted on the top of the movable block 6 via a pin. A clamping frame 9 is mounted on the top of the two connecting bars 8 via a pin. A T-shaped groove 10 is provided on the inner wall of the rectangular groove 3 at a position corresponding to the clamping frame 9. A T-shaped slider 11 is fixedly connected to one side of the clamping frame 9, and the T-shaped slider 11 is slidably connected inside the T-shaped groove 10. An mounting block 14 is fixedly connected to one side of the rotating plate 2. With the T-shaped slider 11, the connecting bar 8 pulls the clamping frame 9 to move up and down inside the rectangular groove 3, causing the T-shaped slider 11 to slide inside the T-shaped groove 10, ensuring that the clamping frame 9 will not tilt or deflect during the up and down movement.

[0021] An arc-shaped groove 12 is provided through one side of the bottom of the rotating plate 2. An arc-shaped slide bar 13 is fixedly connected to the top of the base plate 1, and the arc-shaped groove 12 is slidably connected to the surface of the arc-shaped slide bar 13. Because of the arc-shaped slide bar 13, the rotating plate 2 is pushed to rotate on the top of the base plate 1, which causes the arc-shaped groove 12 to slide on the surface of the arc-shaped slide bar 13, thereby limiting the rotation of the rotating plate 2.

[0022] The bottom of the mounting block 14 is provided with a mounting groove 15, through which a fixing rod 16 is slidably connected. The bottom end of the fixing rod 16 extends through the mounting groove 15 to the outside of the mounting block 14. The top of the base plate 1 is provided with multiple fixing holes 20 at equal angles, and the fixing holes 20 are arranged in an arc. The fixing holes 20 are correspondingly inserted into the fixing rods 16. With the fixing rods 16, the fixing rods 16 push out of the mounting groove 15, extend out of the mounting block 14, and snap into the corresponding fixing holes 20, thereby clamping and fixing the rotating plate 2 to the top of the base plate 1, so that the rotating plate 2 drives the square tube to rotate at a suitable angle for processing.

[0023] A limiting plate 17 is fixedly connected to the bottom surface of the fixed insertion rod 16 inside the mounting groove 15, and a fixing spring 18 is sleeved on the top surface of the fixed insertion rod 16 inside the limiting plate 17. A lever 19 is fixedly connected to the top of the fixed insertion rod 16 inside the mounting groove 15, and the lever 19 extends through the mounting groove 15 to the outside of the mounting block 14. Due to the presence of the fixing spring 18, the limiting plate 17 is pressed down under the rebound action of the fixing spring 18, causing the fixed insertion rod 16 to slide inside the mounting groove 15, pushing the fixed insertion rod 16 out of the mounting groove 15 and inserting it into the corresponding fixing hole 20, thereby clamping and fixing the rotating plate 2.

[0024] The working principle of this utility model is as follows:

[0025] After fixing the base plate 1 to the processing position of the corner cutting machine, lift the lever 19 to drive the fixed insertion rod 16 to move upward and disengage from the fixed insertion hole 20, push the rotating plate 2 to rotate on the top of the base plate 1 until the rotating plate 2 rotates to a suitable angle on the top of the base plate 1. Release the lever 19 and under the rebound action of the fixed spring 18, press the limiting plate 17 into the bottom of the mounting groove 15, so that the fixed insertion rod 16 is inserted into the corresponding fixed insertion hole 20, fix the rotating plate 2 on the top of the base plate 1, move the square tube to fit closely against one side of the rotating plate 2, control the electric push rod 7 to extend and retract to pull the moving block 6 to slide, so that the connecting strip 8 rotates on the top of the moving block 6, pull the clamping frame 9 to move downward inside the rectangular groove 3 and press it on the top of the square tube to clamp and fix the square tube, control the corner cutting machine to process the square tube, and ensure that the square tube will not shake randomly during processing.
