DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4A novel pneumatic flexible clamp device comprises a workbench 1, a pneumatic clamp 2, a rotating device, a spacing adjustment device, a lifting device and a self-locking device. A turntable 3 is installed on the top of the workbench 1 through the rotating device. The spacing adjustment device comprises a first threaded rod 4, a first slider 5 and a first motor 6. Three groups of rectangular grooves 7 are opened in an annular shape on the turntable 3. The first threaded rod 4 is rotatably installed in the rectangular groove 7. One end of the first threaded rod 4 passes through the side wall of the rectangular groove 7 and is installed with the first motor 6. The first slider 5 is installed on the first threaded rod 4 through a bearing. A moving frame 8 is installed on the top wall of a slider 5, and the lifting device includes a second threaded rod 9, a second slider 10 and a second motor 11. A groove body 12 is opened on the side wall of the moving frame 8 near the center of the turntable 3, and the second threaded rod 9 is rotatably installed in the groove body 12. One end of the second threaded rod 9 passes through the side wall of the rectangular groove 7 and is installed with the second motor 11. The second slider 10 is installed on the second threaded rod 9 through a bearing, and the pneumatic clamp 2 is installed on the side wall of the second slider 10 through a connecting rod. A controller 13 is installed on the front end face of the workbench 1. In the example, when in use, first connect the top end of the pneumatic clamp 2 to the air source, then place the workpiece at the center of the turntable 3, and then start the first motor 6 respectively. The output end of the first motor 6 drives the first threaded rod 4 to rotate. During the rotation, the first threaded rod 4 drives the first slider 5 to move linearly in the rectangular groove 7, so that each group of the first slider 5 drives the moving frame 8 to adjust to a suitable distance from the workpiece, and then the gas is compressed and transported to the pneumatic clamp 2 by controlling the air source, so that the pneumatic clamp 2 generates a clamping force, thereby clamping the workpiece, and then processing can be carried out. When it is necessary to adjust the clamping height of the workpiece, start multiple groups of second motors. The machine 11 makes the output ends of the multiple groups of second motors 11 drive the multiple groups of second threaded rods 9 to rotate at the same time. During the rotation process, the second threaded rods 9 drive the second sliders 10 to move linearly in the groove body 12 until the multiple groups of second sliders 10 drive the workpiece fixed by the pneumatic clamp 2 to adjust to the required height to meet the height adjustment requirements. When the workpiece needs to be released, the gas is released by controlling the gas source to make the pneumatic clamp 2 lose its clamping force, thereby releasing the workpiece. When the workpiece is released, the workpiece can be adjusted to the lowest end through the lifting device to facilitate the release of the workpiece. The controller 13 is convenient for controlling the working status of each electrical component in the device.

[0027] During actual use, the turntable 3 is further driven to rotate. In this embodiment, the rotating device includes a rotating motor 14, and the rotating motor 14 is arranged on the bottom wall of the workbench 1. The output end of the rotating motor 14 passes through the side wall of the workbench 1 and is connected to the turntable 3. When the rotating motor 14 is started, the output end of the rotating motor 14 drives the turntable 3 to rotate, thereby realizing the rotation adjustment of the angle of the clamped workpiece.

[0028] In actual use, in order to further prevent the turntable 3 from deviating from its motion trajectory, in this embodiment, a fixing ring 15 is installed on the bottom wall of the turntable 3, and an annular groove 16 is provided on the top wall of the workbench 1. The annular groove 16 is slidably connected to the fixing ring 15. During the rotation of the turntable 3, the fixing ring 15 is driven to slide in the annular groove 16, so as to guide and limit the rotation of the turntable 3 and prevent the turntable 3 from deviating from its motion trajectory.

[0029] In actual use, it is further convenient to lock the turntable 3. In this embodiment, the self-locking device includes an iron block 17 and an electromagnetic plate 18. A plurality of groups of the iron blocks 17 are evenly arranged on the side wall of the fixing ring 15. The electromagnetic plate 18 is installed on one side of the top of the workbench 1. The electromagnetic plate 18 is magnetically connected to the iron block 17. When the turntable 3 is adjusted to a suitable angle by the rotating device and then the electromagnetic plate 18 is energized, the electromagnetic plate 18 is magnetically connected to the iron block 17 at the corresponding position to lock the turntable 3 to prevent the turntable 3 from accidentally shifting.

[0030] In actual use, it is further convenient to detect the distance from the workpiece to each pneumatic clamp 2. In this embodiment, a distance sensor is installed on the side wall of the pneumatic clamp 2. The distance detector is convenient for detecting the distance between each group of pneumatic clamps 2 and the workpiece, so as to control the moving position of each group of movable frames 8.

[0031] In actual use, in order to further facilitate workers to place workpieces, in this embodiment, a positioning plate 19 is installed at the center of the turntable 3. The positioning plate 19 facilitates workers to place the workpiece on the positioning plate 19, which is convenient for later clamping and fixing.

[0032] In actual use, the friction between the workpiece and the pneumatic clamp 2 is further increased. In this embodiment, the clamping surface of the pneumatic clamp 2 is made of anti-slip material to increase the friction between the workpiece and the pneumatic clamp 2 to prevent the workpiece from sliding or falling off during processing.

[0033] During actual use, in order to further ensure the support stability of the workbench 1, in this embodiment, two groups of symmetrically designed support plates 20 are installed on the bottom wall of the workbench 1, and a reinforcing plate 21 is installed between the two groups of support plates 20. The support plates 20 ensure the support stability of the workbench 1, and the reinforcing plates 21 strengthen the connection strength of the two groups of support plates 20.
