Description

Technical Field

[0001] The utility model relates to the technical field of clamp equipment, and more specifically to a precision oil pressure vise. Background Art

[0002] Most of the existing hydraulic vises use a manually controlled oil cylinder to clamp the workpiece. However, these hydraulic vises cannot change the clamp distance according to the size of the workpiece and the maximum pressure they can withstand, resulting in some workpieces being over-squeezed by the hydraulic vise and damaged. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a precision hydraulic vise to solve the problem that most of the existing hydraulic vises in the above-mentioned background technology use manually controlled oil cylinders to clamp the workpiece, but these hydraulic vises cannot change the clamp distance according to the size of the workpiece and the maximum pressure they can withstand, resulting in some workpieces being damaged by excessive squeezing of the hydraulic vise.

[0004] The utility model provides the following technical scheme: a precision hydraulic vise, comprising an equipment base plate, a fixed pliers body is fixedly installed on one side of the top end of the equipment base plate, a first oil cylinder is fixedly installed on the top end of the equipment base plate, a movable pliers body is movably installed on one side of the first oil cylinder, a second oil cylinder is connected to the top end of the first oil cylinder through a pipeline seal, the bottom end of the second oil cylinder is fixedly connected to the top end of the equipment base plate, a threaded through groove is provided on the top end of the second oil cylinder, a threaded telescopic rod is rotatably installed on the threaded through groove of the second oil cylinder, the bottom end of the threaded telescopic rod extends to the interior of the second oil cylinder, and a sealing piston is fixedly installed on the bottom end of the threaded telescopic rod, a rotating handle is fixedly installed on the top end of the threaded telescopic rod, a pressure sensor is provided on one side of the fixed pliers body, and a length ruler is movably installed on the equipment base plate through a magnet. When in use, the user rotates the rotating handle to move the threaded telescopic rod downward inside the second oil cylinder, so that the oil inside the second oil cylinder is compressed into the first oil cylinder and the movable jaw body is extended. At this time, the user can judge the extension distance of the movable jaw body and the pressure condition of the fixed jaw body by observing the pressure sensor reading of the fixed jaw body and the scale position of the length scale, thereby preventing the workpiece from being crushed. In actual use, this effectively solves the problem that most of the existing hydraulic vises use manually controlled cylinders to clamp the workpiece, but these hydraulic vises cannot change the jaw distance according to the size of the workpiece and the maximum pressure they can withstand, resulting in some workpieces being damaged by excessive squeezing of the hydraulic vise.

[0005] Furthermore, an observation window is inlaid on one side of the second oil cylinder, and the material of the observation window is transparent tempered glass. When in use, the user can observe the oil seal inside the second oil cylinder through the observation window, and at the same time observe the pipe wall of the second oil cylinder, so as to prevent the second oil cylinder from being damaged and unable to be replaced in time.

[0006] Furthermore, both sides of the rotating handle are tightly sleeved with handle washers, and the handle washers are made of sponge soft rings. When in use, the user can rotate the rotating handle more easily and comfortably by holding the handle washers of the rotating handle, thereby preventing hand pain.

[0007] Furthermore, a pressure relief valve is provided at one side of the bottom end of the second oil cylinder, and a valve switch handle is provided at the top of the pressure relief valve. When in use, when the user needs to repair the second oil cylinder and the first oil cylinder, the pressure of both oil cylinders needs to be relieved. At this time, the user opens the pressure relief valve to discharge the pressure inside the first oil cylinder and the second oil cylinder.

[0008] Furthermore, two sliding grooves are provided on the bottom plate of the device, and two sliding wheels are provided at the front and rear of the movable clamp body, and the sliding wheels are slidably mounted on the sliding grooves of the bottom plate of the device. When in use, in order to prevent the movable clamp body from separating from the bottom plate of the device, the four sliding wheels on the movable clamp body can be slidably mounted on the sliding grooves of the bottom plate of the device, so that the connection between the movable clamp body and the bottom plate of the device is tighter.

[0009] Furthermore, four fixed suction cups are fixedly installed at the bottom end of the bottom plate of the device, and the material of the fixed suction cups is transparent rubber. When in use, the fixed suction cups can tightly adsorb the device on the horizontal working surface to prevent the device from moving when processing the workpiece.

[0022] Both sides of the rotating handle 115 are tightly fitted with handle washers, and the material of the handle washers is a soft sponge ring.

[0023] Working principle: When in use, since the first oil cylinder 111 and the second oil cylinder 113 are connected by a pipeline, the second oil cylinder 113 and the first oil cylinder 111 are both filled with pressurized oil. At this time, the user rotates the rotating handle 115 to make the threaded telescopic rod 114 drive the sealing piston at the bottom to move downward inside the second oil cylinder 113, so that the oil inside the second oil cylinder 113 is compressed into the first oil cylinder 111 and the movable pliers body 112 is extended. At the same time, since the threaded telescopic rod 114 and the second oil cylinder 113 are engaged with threads, the distance between the movable pliers body 112 and the fixed pliers body 110 will not shrink. At this time, the user can judge the extension distance of the movable pliers body 112 and the pressure condition of the fixed pliers body 110 by observing the pressure sensor reading of the fixed pliers body 110 and the scale position of the length scale 117, thereby preventing the workpiece from being crushed.
