Embodiment Construction

[0037] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0038] refer to Figure 1 to Figure 9 , the present application provides a simple constant pressure fixture, including a guide sleeve 1 , a pressing cylinder 2 and an upper cylinder 3 .

[0039] Wherein, the compression cylinder 2 is arranged in the guide sleeve 1 and can slide back and forth along the length direction of the guide sleeve 1. The compression cylinder 2 is provided with a compression piston 21. The cavity between them is filled with a liquid medium. The bottom end of the upper oil cylinder 3 is fixedly connected with the top end of the compression oil cylinder 2 and communicates with each other. A pressure limiting barrier 31 is placed at the place where the two communicate with each other. A pressure limiting spring 32 is arranged in the inner ...

Abstract

The invention relates to a simple constant-pressure fixture. The simple constant-pressure fixture comprises a guide sleeve, a hold-down oil cylinder and an upper oil cylinder; the hold-down oil cylinder is arranged in the guide sleeve; a hold-down piston is arranged in the hold-down oil cylinder; the bottom end of the upper oil cylinder is fixedly connected with the top end of the hold-down oil cylinder are fixedly connected, and the upper oil cylinder and the hold-down oil cylinder communicate with each other; a pressure limiting barrier part is arranged at the communicating position of the upper oil cylinder and the hold-down oil cylinder; a pressure limiting spring is arranged in the inner cavity of the upper oil cylinder; and a liquid return pipeline which can be selectively opened isfurther connected between the hold-down oil cylinder and the upper oil cylinder. The fixture disclosed by the invention is simple in structure and convenient to operate, is capable of meeting the requirement of having the same hold-down force on workpieces different in thickness, and avoids the defect that a simple hold-down device in the prior art has an excessive hold-down force on a thick workpiece but an insufficient hold-down force on a thin workpiece.

Description

technical field [0001] The invention belongs to the technical field of clamps, and in particular relates to a simple constant pressure clamp. Background technique [0002] When machining the workpiece material, it is usually necessary to use a fixture to fix the workpiece to prevent the plate-shaped workpiece from shaking during machining and affect the accuracy of machining. However, the design defects of the simple fixtures for fixing the workpiece in the prior art are more obvious. For example, the screw nut is used to tighten and clamp the workpiece, and the operation of the rotating screw is relatively cumbersome, which is not conducive to rapid clamping; It is well adapted to the rapid compression of workpieces of different thicknesses, and it is easy to cause the problem of excessive clamping force for thick workpieces and insufficient clamping force for thin workpieces. Therefore, in the face of large-scale workpiece processing, a simple and reliable fixture that ca...
