[0028] The adjustment mechanism includes a rectangular hole 303 opened on the top of the workbench 1, and a mounting frame 306 movably arranged above the rectangular hole 303 for carrying the clamping mechanism;

[0029] The clamping mechanism includes an electric push rod 401 fixedly connected to the inner top wall of the mounting frame 306, and a clamping plate 402 fixedly connected to the output end of the electric push rod 401 for fixing the aluminum strip.

[0030] The adjustment mechanism also includes a servo motor 301 fixedly connected to the outer wall of the workbench 1 , a forward and reverse ball screw 302 fixedly connected to the output end of the servo motor 301 , and a first bearing member and a second bearing member movably arranged on the outer wall of the forward and reverse ball screw 302 .

[0031] The first bearing member includes a movable seat 304 movably arranged on the outer side wall of the forward and reverse ball screw 302, a connecting rod 305 fixedly connected to the top of the movable seat 304, a mounting groove provided on the outer side wall of the connecting rod 305, and a roller 3013 rotatably connected inside the mounting groove;

[0032] The bottom of the mounting frame 306 is fixedly connected to the top of the connecting rod 305 , wherein the top of the connecting rod 305 extends to the outer surface of the workbench 1 through the rectangular hole 303 , wherein the outer side wall of the roller 3013 protrudes from the mounting groove and abuts against the outer side wall of the rectangular hole 303 .

[0033] The second carrier has the same structure as the first carrier, and the two groups are symmetrically arranged about the central axis of the placement table 2 .

[0034] The adjustment mechanism also includes a protective sleeve 307 fixedly connected to the top of the workbench 1, and an electric lifter 308 fixedly connected to the inner bottom wall of the protective sleeve 307;

[0035] The bottom of the placement table 2 is fixedly connected to the output end of the electric lift 308 , wherein the placement table 2 is a T-shaped table, and the outer diameter of the bottom of the placement table 2 is equal to the inner diameter of the protective sleeve 307 .

[0036] The aluminum strip to be processed is placed on the top of the placement table 2, and then the distance between the two mounting frames 306 is adjusted according to the length of the aluminum strip, that is, by starting the servo motor 301, so that the servo motor 301 drives the forward and reverse ball screw 302 to rotate, thereby driving the two connecting rods 305 and the mounting frame 306 to move towards each other, and then the aluminum strip is preliminarily positioned, and then the placement table 2 is driven downward by the electric lift 308, so that the aluminum strip is suspended in the air, which is convenient for subsequent processing of the aluminum strip.

[0037] When the connecting rod 305 moves, it will drive the roller 3013 to roll along the inner wall of the rectangular hole 303, so as to limit the movable seat 304 and reduce the wear of the rectangular hole 303, thereby increasing the service life of the device.

[0038] Embodiment 2: Figure 1-5 As shown, a fixture for processing aluminum plates and strips includes a workbench 1, and a placement table 2 movably arranged on the top of the workbench 1, and also includes an adjustment mechanism connected to the side wall of the workbench 1, and a clamping mechanism connected to the adjustment mechanism;

[0039] The adjustment mechanism includes a rectangular hole 303 opened on the top of the workbench 1, and a mounting frame 306 movably arranged above the rectangular hole 303 for carrying the clamping mechanism;

[0040] The clamping mechanism includes an electric push rod 401 fixedly connected to the inner top wall of the mounting frame 306, and a clamping plate 402 fixedly connected to the output end of the electric push rod 401 for fixing the aluminum strip.

[0041] The adjustment mechanism also includes a limit rod 309 fixedly connected to the bottom of the placement table 2, a fixed sleeve 3010 fixedly connected to the inner bottom wall of the protective sleeve 307, a transmission block 3011 fixedly connected to the bottom of the limit rod 309, and a stop switch 3012 fixedly installed on the inner wall of the fixed sleeve 3010, wherein when the transmission block 3011 abuts against the stop switch 3012, the stop switch 3012 will turn off the electric lift 308, thereby making the upper surface of the placement table 2 flush with the upper surface of the bottom plate of the mounting frame 306.

[0042] The clamping mechanism also includes a spring groove opened at the bottom of the clamping plate 402, a connecting spring 403 fixedly connected to the bottom of the spring groove, a movable block 404 fixedly connected to the end face of the connecting spring 403, and a travel switch 405 embedded in the inner wall of the spring groove. The electric push rod 401 is closed by the travel switch 405 to ensure that the pressure of the clamping plate 402 on the aluminum strip is controllable.

[0043] When the aluminum strip is placed, the electric push rod 401 is started to drive the clamping plate 402 to move downward. During this process, the movable block 404 will first contact the top of the aluminum strip, thereby pushing the movable block 404 to move toward the inside of the spring groove and compressing the connecting spring 403 until the top of the movable block 404 is against the travel switch 405. At this time, the travel switch 405 will close the electric push rod 401, and the clamping plate 402 will be against the top of the aluminum strip to fix the aluminum strip.

[0044] When the processing is completed, the aluminum plate strip is removed and the electric lift 308 is started, so that the electric lift 308 drives the placement table 2 and the transmission block 3011 to move until the transmission block 3011 touches the stop switch 3012, so that the stop switch 3012 turns off the electric lift 308. At this time, the upper surface of the placement table 2 is flush with the upper surface of the bottom plate of the mounting frame 306, thereby ensuring that the top of the side wall of the aluminum plate strip can be moved to the bottom of the clamping plate 402.
