It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0022] like Figure 1-3 As shown, the present invention proposes a clamping mechanism for feeding materials in a laser cutting machine, comprising a base 1 and an air cylinder 5;

[0023] In this embodiment, a T-shaped seat 2 and a driving member for driving the T-shaped seat 2 to move horizontally are installed on the base 1; the driving member includes a cylinder 10, a slide groove is provided on the top of the base 1, and the bottom of the T-shaped seat 2 is slidably connected to the slide groove, the cylinder 10 is installed at the end of the base 1 away from the fixed rod 7, the T-shaped seat 2 is connected to the cylinder 10 and is driven by the cylinder 10 to move horizontally back and forth along the slide groove; a material discharge cover 3 is installed on the base 1, which is located above the T-shaped seat 2 and fits with it. A through material discharge channel is provided in the material discharge cover 3.

[0024] In this embodiment, a clamping block 4 is installed at one end of the T-shaped seat 2, a clamping groove is opened in the clamping block 4, an elastic push-pull limiter 6 is provided in the air cylinder 5, which passes through the clamping block 4 and extends into the clamping groove, and a fixing rod 7 is installed at one end of the base 1, and the fixing rod 7 is used to push the elastic push-pull limiter 6 to move outward into the air cylinder 5. The elastic push-pull limiter 6 includes a piston 61, a limit rod 62, a spring 63, a push-pull rod 64 and a fixed plate 65. The piston 61 is slidably arranged in the air cylinder 5. The limit rod 62 is installed at one end of the piston 61, and the end of the limit rod 62 away from the piston 61 slides through the side of the clamping block 4 and extends into the clamping groove. The spring 63 is sleeved on the limit rod 62 and is located in the air cylinder 5, and the two ends of the spring 63 are respectively connected to the piston 61 and the side of the clamping block 4. The push-pull rod 64 is installed at the end of the piston 61 away from the limit rod 62, and the end of the push-pull rod 64 away from the piston 61 slides through the end of the air cylinder 5 away from the clamping block 4. The fixed plate 65 is installed at the end of the push-pull rod 64 away from the piston 61, and the fixed plate 65 is located at the end of the fixed rod 7 away from the base 1.

[0025] It should be noted that: in order to realize automatic loading and clamping of the workpiece, the cylinder 10 can be used to drive the T-shaped seat 2 to move horizontally, so that the clamping block 4 is placed under the lower material cover 3. When the clamping block 4 moves to the position below the lower material cover 3, the fixing rod 7 at the end of the base 1 can push the fixing plate 65 away from the gas cylinder 5, and the push-pull rod 64 drives the piston 61 to move backward in the gas cylinder 5. The limit rod 62 connected to the piston 61 enters the gas cylinder 5, and the workpiece in the lower material cover 3 immediately enters the clamping groove opened in the clamping block 4, and then The cylinder 10 drives the T-shaped seat 2 to drive the clamping block 4 away from the position below the material cover 3. After the fixed plate 65 loses the restriction of the fixed rod 7, the limit rod 62 can be restored to its original position under the action of the spring 63, and the workpiece in the clamping block 4 can be clamped during the return process. The workpiece in the material cover 3 can be blocked by the T-shaped seat 2. After the clamped workpiece is processed, the next workpiece can be processed according to the above steps. This structure can realize automatic loading and clamping of the workpiece, thereby improving the processing efficiency.

[0026] In this embodiment, the bottom of the clamping block 4 is connected to a fan discharge member 8 connected to the clamping groove, and an air guide pipe 9 is connected between the air cylinder 5 and the fan discharge member 8. The fan discharge member 8 includes a discharge pipe 81, a bar block 82 and an axial flow fan 83. The discharge pipe 81 is connected to the bottom of the clamping block 4, and a discharge channel that penetrates and connects to the clamping groove is opened in the discharge pipe 81. The bar block 82 is horizontally installed in the discharge channel, and the axial flow fan 83 is rotatably installed at the bottom of the bar block 82. The two ends of the air guide pipe 9 are respectively connected to the air cylinder 5 and the discharge channel, and one end of the air guide pipe 9 is arranged toward the axial flow fan 83.

[0027] It should be noted that: in order to facilitate the cleaning of waste chips in the clamping block 4, when the piston 61 moves in the air cylinder 5, external air can enter the air cylinder 5 along the discharge pipe 81 and the air guide pipe 9. After the workpiece is processed, it can be taken out of the clamping block 4. After the limit rod 62 loses the restriction of the workpiece, the piston 61 is pulled to move in the air cylinder 5 under the action of the spring 63, so that the limit rod 62 returns to its original position. During the movement, the piston 61 pushes out the air entering the air cylinder 5, so that the air enters the discharge pipe 81 along the air guide pipe 9 and is then discharged. When the gas blows toward the axial flow fan 83, it can drive it to rotate, so that wind discharged outward is generated in the discharge pipe 81, and the waste chips in the clamping block 4 are discharged along the discharge pipe 81. This structure can clean the waste chips in the clamping block 4 in time after the workpiece processing is completed, thereby improving the quality of subsequent workpiece processing.

[0028] In a specific embodiment, a filter screen 11 is disposed in the air duct 9 .

[0029] It should be noted that the filter screen 11 can prevent the waste discharged from the discharge pipe 81 from entering the air cylinder 5 along the air guide pipe 9 .
