[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5 The utility model provides a technical solution: a floating clamping device for a bending machine, including a device connecting seat 1, which is installed on the bending turntable 15 of the bending machine. The conveying limiting wheel 17 on the bending machine conveys the workpiece 16 to be processed to between the bending turntable 15 and the clamping device. A fixing hole 2 is opened on the device connecting seat 1, and a hexagon socket bolt is completely embedded in the fixing hole 2. The device connecting seat 1 is fixedly connected to the bending turntable 15 through the hexagon socket bolt.

[0024] Furthermore, the device connecting seat 1 is embedded in the bending turntable 15, and the device connecting seat 1 is flush with the outer side surface of the bending turntable 15, which can ensure that the clamping seat 9 on the device connecting seat 1 can move freely, avoid being affected by the height difference between the connection position of the bending turntable 15 and the device connecting seat 1, and ensure that the activity state of the clamping seat 9 is stable.

[0025] A movable seat 5 is provided on the device connecting seat 1 , and an adjustment component for adjusting the working position of the movable seat 5 is provided between the movable seat 5 and the device connecting seat 1 .

[0026] Furthermore, the adjustment component includes a rotating nut 3 and a fixed screw 4. The rotating nut 3 is a rotating structure on the device connecting seat 1 through a bearing, so that the rotating nut 3 can rotate freely while its position on the device connecting seat 1 remains unchanged. The fixed screw 4 is fixedly connected to the movable seat 5, and the fixed screw 4 passes through the device connecting seat 1 and is threadedly connected to the rotating nut 3. The position movement of the movable seat 5 can be controlled by the connection between the rotating nut 3 and the fixed screw 4, thereby adjusting the working position of the movable seat 5.

[0027] Furthermore, a slide groove 10 is provided on the device connecting seat 1 , and a slider 14 is fixed on the movable seat 5 . The slider 14 has a sliding structure in the slide groove 10 , which can ensure that the movable state of the movable seat 5 is stable.

[0028] Furthermore, the vertical sections of the slider 14 and the slide groove 10 are both rectangles of the same size. The sliders 14 are symmetrically arranged on both sides of the fixed screw 4 to enhance the force performance of the movable seat 5 during operation and ensure the stable working state of the movable seat 5.

[0029] A pressing seat 9 is provided on the movable seat 5 , and a pressing assembly for controlling the working position of the pressing seat 9 is provided between the pressing seat 9 and the movable seat 5 .

[0030] Furthermore, the clamping assembly includes a movable screw 6, a hexagonal bolt head 8, a limiting rod 11, a connecting head 12 and a spring 13. The movable screw 6 passes through the movable seat 5 and is threadedly connected thereto, so that the position of the movable screw 6 can be moved up and down on the movable seat 5. The hexagonal bolt head 8, the limiting rod 11 and the connecting head 12 are integrated. The limiting rod 11 passes through the movable seat 5, and the connecting head 12 is threadedly connected to the clamping seat 9, so that the clamping seat 9 can be installed on the movable seat 5, which is also convenient for disassembly and assembly of the clamping seat 9. The spring 13 is sleeved on the limiting rod 11, and the upper end of the spring 13 is connected to the hexagonal bolt head 8, and the lower end of the spring 13 is connected to the movable seat 5. Through the cooperation of the spring 13 and the movable screw 6, the clamping seat 9 forms a floating structure on the movable seat 5, and then through the floating setting of the clamping seat 9, the position of the clamping seat 9 can be more conveniently moved, thereby improving the extrusion work efficiency of the clamping seat 9.

[0031] Furthermore, a rotating head 7 is fixed to the upper end of the movable screw 6, and the lower end of the movable screw 6 is spherical. The lower end of the movable screw 6 is in contact with the clamping seat 9, so that the movable screw 6 only pushes the clamping seat 9, which makes the operation process of the movable screw 6 more convenient.

[0032] Furthermore, the hexagonal bolt head 8 and the limit rod 11 are both embedded in the connecting groove on the movable seat 5, and the outer diameter of the hexagonal bolt head 8 is equal to the inner diameter of the connecting groove on the movable seat 5, ensuring that the limit rod 11 is in a stable active state on the movable seat 5.

[0033] Specifically, when using the floating clamping device of the bending machine, the device connecting base 1 is first fixedly installed on the bending turntable 15 by means of hexagon socket bolts. A plurality of fixing holes 2 are provided on the device connecting base 1, and the installation position of the device connecting base 1 can be adjusted, thereby enabling the clamping device to cooperate with the bending turntable 15 to bend different workpieces;

[0034] After the device connecting seat 1 is fixed, a suitable pressing seat 9 is selected according to the external dimensions of the workpiece to be bent. For example, if the workpiece is a round tube or a rod, a pressing seat 9 with a concave inner side can be selected to better fit the workpiece and ensure that the workpiece is pressed stably.

[0035] After the pressing seat 9 is selected, it is installed on the movable seat 5. First, the spring 13 is put on the limiting rod 11, and the limiting rod 11 with the spring 13 is installed on the movable seat 5. The limiting rod 11 passes through the movable seat 5 and is fixedly connected to the pressing seat 9 through the connecting head 12, thereby realizing the installation of the pressing seat 9 on the movable seat 5;

[0036] At the same time, before installing the pressing seat 9, it is necessary to adjust the position of the movable seat 5 so that the movable seat 5 has a suitable position to install the pressing seat 9. Since the installation position of the pressing seat 9 on the movable seat 5 is fixed, in order to ensure that the pressing seat 9 is in the middle position when squeezing the bent workpiece, it is necessary to adjust the position of the movable seat 5 to adjust the contact position between the pressing seat 9 and the workpiece.

[0037] When adjusting the position of the movable seat 5, the nut 3 is rotated to change the position of the movable seat 5 on the device connecting seat 1 through the fixed screw 4. At the same time, under the action of the slider 14, the movable state of the movable seat 5 can be ensured to be stable, and the force performance of the movable seat 5 can be enhanced, thereby ensuring that the pressing seat 9 can squeeze the bent workpiece stably;

[0038] When the movable seat 5 and the pressing seat 9 are ready for working, the movable screw 6 can be rotated by the rotating head 7 to push the pressing seat 9 to squeeze the workpiece, and the bending turntable 15 rotates, and the workpiece can be bent in conjunction with the pressing device.

[0039] When the bending work is completed, the movable screw rod 6 is rotated in the opposite direction, and the pressing seat 9 floats upward under the action of the spring 13, quickly and automatically releasing the pressing state of the workpiece. If a workpiece of another size is replaced for bending, the corresponding pressing seat 9 is replaced, and the position of the movable seat 5 is adjusted to ensure that the movable seat 5 acts on the middle position of the workpiece through the pressing seat 9, thereby ensuring that workpieces of different sizes can be stably pressed;

[0040] The above completes the working process of the pressing device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
