[0024] Embodiment 1

[0025] like Figure 1-4 As shown, a movably positioned multi-station air cushion comprises: a guide rail 1, a slider 2, a locking piece 3, a seat body 4, and a cylinder 5. The guide rail 1 is connected to the base 6 of the press machine, the slider 2 is slidably set on the guide rail 1, the locking piece 3 is connected to the slider 2, the seat body 4 is located below the guide rail 1 and is set on the locking piece 3, the locking piece 3 is used to clamp the slider 2 and the seat body 4 to the guide rail 1, the cylinder 5 is installed on the seat body 4, and the upper end of the cylinder 5 is connected to the crown 7 set in the base 6.

[0026] Specifically, Figure 1-4 As shown, the base 6 is provided with a base plate 8 corresponding to the guide rail 1, there are two guide rails 1 and they are spaced apart in the front-to-rear direction of the base 6, the guide rail 1 is installed at the lower end of the base plate 8 along the length direction of the base plate 8, there are multiple top crowns 7 and they are spaced apart in sequence along the length direction of the base 6 (one of them is shown in the figure), and each top crown 7 is connected to an independent cylinder 5, thereby forming a multi-station air cushion structure.

[0027] Specifically, Figure 3 As shown, the guide rail 1 is provided with a T-shaped guide groove, the slider 2 is an inverted T-shaped structure and is inserted into the guide groove with clearance and sliding. Through the T-shaped guide structure, the cylinder 5 can be guided to move along the direction of the guide groove.

[0028] Specifically, Figure 3As shown, the locking member 3 includes: a cylinder body 301, a locking rod 302, and an elastic member 303. The upper end of the locking rod 302 is connected to the slider 2, and the lower end of the locking rod 302 is slidably set in the cylinder body 301 and divides the cylinder body 301 into a first cavity and a second cavity. The first cavity is located above the second cavity, and the first cavity is used to pass hydraulic oil. The elastic member 303 is located in the second cavity. The elastic member 303 applies an upward elastic force to the locking rod 302, and the position of the locking rod 302 is controlled by the hydraulic oil, thereby realizing the function of the slider 2 and the seat body 4 clamping the guide rail 1 or loosening the guide rail 1. This structure can easily realize the function of switching the air cushion between the positioning state and the displaceable state.

[0029] Specifically, Figure 3 As shown, a piston is arranged at the lower end of the locking rod 302, and the piston is slidably inserted in the cylinder body 301. The upper end of the locking rod 302 is threadedly connected to the slider 2. The elastic member 303 adopts a compression spring. The cylinder body 301 and the compression spring corresponding to the piston are both provided with a positioning groove. The hydraulic system controls the hydraulic oil to enter the first cavity, and cooperates with the elastic member 303 to realize the function of the locking rod 302 moving up and down. When the first cavity enters oil, the piston moves downward under pressure and compresses the spring. The locking rod 302 drives the slider 2 to move downward, so that the slider 2 and the seat body 4 clamp the guide rail 1 on both sides of the guide rail 1, thereby locking the seat body 4 and the slider 2 to the guide rail 1. When the hydraulic system controls the hydraulic oil to be discharged from the first cavity, the spring applies an upward reset force to the piston, and the clamping force jointly generated by the slider 2 and the seat body 4 disappears, and the seat body 4 and the slider 2 are in a displaceable state.

[0030] Specifically, Figure 3 As shown, the cylinder 5 is a three-layer cylinder 5. The three-layer cylinder 5 structure reduces the cross-sectional area of ​​a single cylinder 5, which facilitates the arrangement of the cylinder 5 in a multi-station structure.

[0031] Specifically, Figure 3As shown, the cylinder 5 has three layers of cylinder sleeves, which are stacked vertically in sequence, with partitions arranged between each layer of cylinder sleeves, and a cover plate at the lower end of the lowest cylinder sleeve, which is connected to the seat body 4 by a screw, and the end of the screw rod passes through the cover plate and the seat body 4 and is connected with a nut, and the cylinder sleeve and the partition plate are positioned by pressing the cover plate, and the cylinder 5 is separated into an upper cavity 501, a middle cavity 502, and a lower cavity 503 in the cylinder sleeve by the partition plate, and an upper piston is slidably arranged in the upper cavity 501, a middle piston is arranged in the middle cavity 502, and a lower piston is arranged in the lower cavity 503. The cylinder 5 is also equipped with a piston rod and a shaft body, and the upper piston, the middle piston, and the lower piston are sequentially mounted on the piston rod and locked at the corresponding shaft shoulders by nuts, and the piston The upper end of the rod is threadedly connected to the threaded hole opened on the shaft body through a threaded structure, and the upper piston, the middle piston, and the lower piston are slidably inserted in the corresponding cylinder sleeves. An air channel 504 is opened along the axis of the piston rod, and the cover plate is connected to the air path system through a pipeline. The area between the cover plate and the lower piston is supplied with air through the air path system. There is a gap between the middle piston and the adjacent partition below, and there is a gap between the upper piston and the adjacent partition below. The piston rod is also provided with a through hole connecting the air channel 504 with the above-mentioned gap. The function of applying pressure to the upper piston, the middle piston, and the lower piston at the same time is realized through this structure, thereby increasing the external force applied to the shaft body, facilitating the reduction of the diameter of the cylinder sleeve, and avoiding interference between adjacent cylinders 5 in the multi-station structure.

[0032] This type of movably positioned multi-station air cushion has a slider 2 designed as a hydraulic clamping and positioning structure with the guide rail 1. When the position of the top crown 7 needs to be changed, it is only necessary to discharge the hydraulic oil in the locking member 3, so that the air cushion is in a position-adjustable state. Compared with the air cushion structure installed with bolts, the position adjustment function can be achieved without disassembling the air cushion, thereby having the advantage of easy adjustment of the air cushion position.

[0033] Embodiment 2

[0034] Based on the first embodiment, Figure 1 As shown, the movably positionable multi-station air cushion also includes: a first sensing member 9, a second sensing member 10, and a sensing block 11. The first sensing member 9 is arranged on the base body 4, the second sensing member 10 is spaced apart from the first sensing member 9 and installed on the base body 4, the sensing block 11 is connected to the guide rail 1 and is located between the first sensing member 9 and the second sensing member 10. The position of the sensing block 11 is detected by the first sensing member 9 and the second sensing member 10, thereby detecting the left and right extreme positions of the movement of the cylinder 5.

[0035] Specifically, the first sensing element 9 and the second sensing element adopt proximity switches. The same cylinder 5 is equipped with four proximity switches. The proximity switches are grouped in pairs and installed on the side of the base body 4. The sensing block 11 is installed in the corresponding installation groove of the guide rail 1. The proximity switch detects the sensing block 11, thereby sending a signal that the cylinder 5 moves to the extreme position, which is convenient for the operator above the pit to observe the position of the cylinder 5.
