The utility model aims at overcoming the defect that prior art exists, provide a hydraulic pressure follow rest.
Realize the utility model discloses the technical scheme of purpose is: a hydraulic follow rest is provided with a base plate, a shell, a hydraulic oil cylinder, a connecting rod and a clamping jaw; the hydraulic oil cylinder is characterized in that a shell is fixed on the bottom plate, a hydraulic oil cylinder is arranged on the end face of the right side of the shell, two connecting rods are hinged to two sides of the end of a piston rod of the hydraulic oil cylinder respectively, the other ends of the two connecting rods are hinged to a clamping jaw respectively, and the middle sections of the two clamping jaws are hinged to the shell.
Furthermore, the connecting rod is hinged to the end of the piston rod of the hydraulic oil cylinder through a connecting rod shaft, two transverse waist holes are respectively formed in the two sides of the shell at the corresponding positions of the connecting rod shaft, and the two ends of the connecting rod shaft are movably arranged in the transverse waist holes.
Furthermore, the two clamping jaws are arranged in an up-and-down symmetrical mode, and the tail ends of the two clamping jaws are respectively hinged with a Y-shaped jaw block.
Furthermore, a jaw strip is fixed on the inner side of the jaw block.
Furthermore, the shell is provided with a jaw avoiding opening at the upper and lower positions of the jaw.
Furthermore, a jaw avoiding opening is also formed in the bottom plate.
After the technical scheme is adopted, the utility model discloses following positive effect has:
(1) the utility model discloses simple structure, through hydro-cylinder control, machining efficiency is higher.
(2) The utility model discloses
Drawings
In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is given in conjunction with the accompanying drawings, in which
Fig. 1 is a schematic structural view of the present invention;
