[0030] like Figure 1 As shown, a double-bar, double-force hydraulic device includes a bed 1, a hydraulic cylinder 2, a conveying device, and an auxiliary clamping device. The hydraulic cylinder 2 is located in the middle of the bed 1, the conveying device is located at the bottom of the bed 1, and the auxiliary clamping device is located at both ends of the bed 1. The auxiliary clamping device includes a driving device, a clamping device, and an auxiliary rod. The clamping device is movably connected to the driving device, and the auxiliary rod is located on the side of the conveying device. The conveying device is located within the bed 1, and the clamping device is located at both ends of the bed 1 via the driving device and the auxiliary rod. The clamping device is moved by the driving device.

[0031] like Figure 1 As shown, the auxiliary rod includes a first auxiliary rod 3 and a second auxiliary rod 4. The first auxiliary rod 3 is arranged on one side of the conveying equipment, and the second auxiliary rod 4 is arranged on the other side of the conveying equipment. The length of the first auxiliary rod 3 is greater than the length of the bed 1, and one end of the second auxiliary rod 4 is arranged on the outside of the bed 1.

[0032] like Figure 1 As shown, the driving device includes a driving motor 5 and a screw 6 fixedly connected to the driving motor 5. The driving device is arranged on the side of the second auxiliary rod 4 close to the conveying device. The driving motor 5 drives the screw 6 to rotate, and the screw 6 drives the clamping device to rotate and move.

[0033] like Figure 3 and Figure 4 As shown, the clamping device includes a connecting rod 7 and a clamping plate 8. The clamping plate 8 is fixed to the middle of the connecting rod 7. A nut seat 9 is provided at one end of the connecting rod 7, and a limit block 10 is provided at the other end of the connecting rod 7. The nut seat 9 is cooperatively connected with the screw rod 6, and the limit block 10 is in contact with the auxiliary rod. The length of the connecting rod 7 is equal to the distance between the screw rod 6 and the first auxiliary rod 3. When the clamping device is not in use, the limit block 10 is placed on the second auxiliary rod 4. When the clamping device is in mobile mode, the limit block 10 is placed on the first auxiliary rod 3 and is in contact with the auxiliary rod.

[0034] like Figure 1 As shown, the middle portion of the bed 1 forms a conveying trough 11 downwardly, and the conveying equipment is disposed in the conveying trough 11. The conveying equipment includes two sets of conveying rollers 12 and a correction platform 13. The correction platform 13 is disposed in the middle portion of the conveying trough 11, and the two sets of conveying rollers 12 are disposed on both sides of the correction platform 13. The workpiece is placed in the conveying trough 11 and moved, and hydraulic correction is performed at the position of the correction platform 13.

[0035] like Figure 2 and Figure 6 As shown, there are two hydraulic cylinders 2, which are respectively arranged on the upper part of the bed 1 and one side of the conveying trough 11. The two hydraulic cylinders 2 are vertically arranged in the same vertical plane, and can simultaneously correct the two vertical surfaces of the workpiece to be corrected.

[0036] like Figure 3 、 4 As shown, the clamping plate 8 is provided with an adjustment plate 14, one side of which is connected to an adjustment screw 15, which is threadedly connected to the clamping plate 8. The other end of the adjustment screw 15 is provided with a handle 16. When the clamping plate 8 moves to the sides of the calibration platform 13, if the workpiece cannot be fixed, the position of the adjustment plate 14 is adjusted by rotating the adjustment screw 15 to fix the workpiece.

[0037] like Figure 6 As shown, the two hydraulic cylinders 2 are connected via an oil circuit 17 .

[0038] The bed body 1 is provided with a control box 18. The model of the control box 18 and the type of related controller are well known to those skilled in the art and will not be described in detail here.

[0039] The sum of the length of the screw rod 6 and the length of the adjusting screw 15 is greater than the length of the conveying roller 12. If the clamping plate 8 is still unable to fix the workpiece when it is located at the end of the bed 1, the adjusting plate 14 is further adjusted outward by rotating the adjusting screw 15 to fix the workpiece.

[0040] Directions:

[0041] When the device is used, the workpiece is loaded from one end of the bed 1;

[0042] The workpiece is placed in the conveying trough 11, and is fed into the bed 1 along the conveying roller 12, and the position to be corrected is placed on the correction platform 13;

[0043] By controlling the operation of the drive motor 15, the drive motor 15 drives the clamping device to rotate in the direction of the conveying trough 11. At this time, the limit block 10 moves from the second auxiliary rod 4 to the first auxiliary rod 3. The clamping device no longer rotates and moves forward in the direction of rotation of the screw rod 6. When the clamping plate 8 contacts the workpiece, the drive motor 15 stops operating.

[0044] By controlling the hydraulic cylinder 2 to perform hydraulic correction on the upper and right sides of the workpiece to be corrected, the workpiece can be corrected in four directions: up, down, left, and right.

[0045] After the workpiece is calibrated, the drive motor 15 drives the screw 6 to rotate, and the screw 6 drives the clamping device to rotate upward until the limit block 10 contacts the second auxiliary rod 4. The clamping device stops rotating and continues to move forward in the direction of rotation of the screw 6 until the drive motor 15 stops after it is reset.

[0046] If the clamping device still cannot contact the workpiece when it reaches the end of the screw rod 6, the adjusting screw 15 is manually rotated to make the adjusting plate 14 contact and fix the workpiece.

[0047] The above-mentioned specific embodiments are only specific cases of the present invention. The patent protection scope of the present invention includes but is not limited to the product form and style of the above-mentioned specific embodiments.
