Problems solved by technology

[0002] In today's mechanical processing field, people usually use vises to fix the workpiece effectively and stably. The existing vise has the following defects: when tightening the workpiece, it is necessary to continuously rotate the drive rod to adjust the fixed vise The size of the jaw between the seat and the movable clamp seat, and then the workpiece is clamped by manpower pressure, and when the workpiece is loosened, the same manpower is required to adjust the jaw to complete the relaxation of the workpiece. Time-consuming and labor-intensive, and cannot guarantee sufficient clamping force on the workpiece

Embodiment Construction

[0012] Specific embodiments of the present invention are described below in conjunction with accompanying drawing:

[0013] Such as figure 1 As shown, a hydraulic fastening device includes a support table 1 for supporting the entire hydraulic fastening device components, and a clamping block 2 is arranged symmetrically on the support table 1 for clamping a workpiece; the clamping block 2 is hydraulically The cylinder 3 is driven, and the workpiece can be slowly clamped. On the one hand, it will not damage the surface of the workpiece, and on the other hand, it can gradually apply force according to the needs; the hydraulic cylinder 3 is powered by the hydraulic pump 4, and the hydraulic pump is connected to the oil tank 5. as a power source.

[0014] Wherein, a gear-rack structure 6 is also provided on the support table 1, and the gear-rack structure 6 includes two racks and a gear meshed with each other, wherein the two racks are fixed on each clamping block 2 The lower end...

Abstract

The invention provides a hydraulic fastening device, comprising a support platform, a clamping block symmetrically arranged on the support platform, a hydraulic cylinder driving the clamping block, a hydraulic pump connected to the hydraulic cylinder, and the hydraulic pump is connected to an oil tank. The beneficial effects of the present invention are: adopting the above technical scheme, the clamping block is pushed by the hydraulic cylinder to clamp the workpiece, which can reduce the application of manpower, and at the same time, the clamping effect is good and the stability is high; and the clamping can be gradually adjusted as required intensity.

Description

technical field [0001] The invention relates to the technical field of vise equipment, in particular to a hydraulic fastening device. Background technique [0002] In today's mechanical processing field, people usually use vises to fix the workpiece effectively and stably. The existing vise has the following defects: when tightening the workpiece, it is necessary to continuously rotate the drive rod to adjust the fixed vise The size of the jaw between the seat and the movable clamp seat, and then the workpiece is clamped by manpower pressure, and when the workpiece is loosened, the same manpower is required to adjust the jaw to complete the relaxation of the workpiece. It is time-consuming and labor-intensive, and sufficient clamping force to the workpiece cannot be guaranteed. Contents of the invention [0003] The problem to be solved by the present invention is to provide a hydraulic fastening device, which can reduce the application of manpower, has good stability in ...
