Technical Field

[0001] The utility model relates to the technical field of servo hydraulic machines, in particular to a clamping device for energy-saving transformation of a hydraulic servo. Background Art

[0002] A servo hydraulic press, also known as a servo-driven hydraulic press, is a hydraulic press that uses a servo motor to drive the main transmission oil pump, thereby reducing the control circuit and controlling the movement of the hydraulic press slide. It is mainly used in processes such as stamping, die forging, press fitting and straightening. In the process of using a hydraulic press, a clamping device is usually used to fix the workpiece, thereby providing support and positioning effects when processing the workpiece, facilitating the workpiece processing process.

[0003] Prior art, such as the utility model with publication number CN215397179U, discloses a workpiece clamping device for hydraulic presses, which relates to the field of hydraulic presses. In view of the problem that the hydraulic presses currently do not take clamping measures for the workpieces when performing hydraulic work on the workpieces, resulting in the workpieces slipping, the following scheme is proposed, which includes a bottom plate, a workbench is fixedly installed on the top of the bottom plate, and a collecting trough is arranged on one side of the workbench, the collecting trough is connected to the bottom plate, there are two groups of collecting troughs, and they are symmetrically distributed about the workbench, the side of the collecting trough close to the workbench is inclined and has the same height as the workbench, the side of the collecting trough away from the workbench is higher than the workbench, and an electric push rod is arranged on one side of the collecting trough, and the electric push rod passes through the collecting trough and extends to the outside. The workpiece clamping device for hydraulic presses can not only collect the debris or mixed liquid generated by the hydraulic rod when processing the workpiece through the collecting trough, but also separate the solid and liquid through the filter layer.

[0039] Working principle: When using the hydraulic servo energy-saving modification clamping device to clamp the workpiece to be processed, first connect the hydraulic servo energy-saving modification clamping device to an external power supply, place the workpiece to be processed on the surface of the workbench 2 on the base 1, and then start the first electric retracting rod 304 and the second electric retracting rod 310 on the first collecting slot plate 301 and the second collecting slot plate 307 of the clamping mechanism 3 respectively, so that the first electric retracting rod 304 and the second electric retracting rod 310 respectively drive the first clamping block 305 and the first rubber plate 306 and the second clamping block 311 and the second rubber plate 312 to move close to the workpiece to clamp the workpiece, and the first electric retracting rod 304 and the second electric retracting rod 310 can be installed by setting the first mounting plate 303 and the second mounting plate 309, and the workpiece debris on the workbench 2 can be collected by setting the first connecting plate 302 and the second connecting plate 308. When the surface of the workbench 2 needs to be cleaned, first start the two first electric retracting rods 304 to drive the two first clamping blocks 305 to move closer to each other, then pull the two control plates 49, so that the four circular plates 47 respectively drive the limit rods 46 to slide on the inner wall of the mounting block 41, so that the control plate 49 moves away from the mounting block 41, and the moving plate 43 drives the insertion rod 42 to move closer to the mounting block 41, so that the insertion rod 42 is stuck in the socket on the mounting block 41, and the control plate 49 is released. Under the action of the elastic force of the first spring 48, the limit rod 46 moves closer to the insertion rod 42, adjusting the position of the insertion rod 42. The setting is restricted to complete the installation of the scraper 45, and then the two first electric retracting rods 304 are started to control the two first clamping blocks 305 to move away from each other, so that the surface of the workbench 2 is cleaned by the scraper 45. By setting the connecting rod 44, the scraper 45 can be installed. By setting the cleaning device 4, the surface of the workbench 2 can be cleaned by controlling the movement of the first electric retracting rod 304, thereby ensuring that the workbench 2 is cleaned as thoroughly as possible, while facilitating the cleaning work of the staff and improving the efficiency of cleaning the surface of the workbench 2.

[0040] When clamping and fixing the workpiece, first place the workpiece on the upper surface of the workbench 2, then pull the pull plate 58 to drive the square rod 57 to slide on the inner wall of the rotating plate 52, so that the square rod 57 moves away from the cylinder 51, rotate the rotating plate 52 to make it rotate on the surface of the cylinder 51, thereby controlling the rotating plate 52 to move close to the workpiece, rotate the limit plate 54 to make the screw 53 rotate on the inner wall of the rotating plate 52, control the abutment plate 55 and the rubber pad 56 to move close to the workpiece, temporarily fix the workpiece, release the pull plate 58, and under the action of the elastic force of the second spring 59, the square rod 57 moves close to the cylinder 51 to limit the rotation of the rotating plate 52, and then control the first clamping block 305 and the second clamping block 311 to move close to the workpiece to fix the position of the workpiece. , pull the pull plate 58 to drive the square rod 57 to move away from the cylinder 51, rotate the rotating plate 52 to move away from the workpiece, release the pull plate 58, and under the action of the elastic force of the second spring 59, the square rod 57 moves close to the cylinder 51 to limit the rotation of the rotating plate 52. By setting the limit device 5, when it is necessary to use the hydraulic servo energy-saving modification clamping device to clamp the workpiece to be processed, the position of the workpiece can be temporarily limited, so as to ensure as much as possible that the workpiece will not move when the first clamping block 305 and the second clamping block 311 are used to clamp the workpiece. At the same time, by setting the square rod 57, the rotating plate 52 can be positioned at the center of the workbench 2 after rotation, which can play a positioning effect on the workpiece as much as possible.
