In the present case, the piston-rod lower end of described cylinder carries the rubber blanket that is played cushioning effect, so just can avoid the direct and absorption surface of the piston rod of cylinder, thus prevent from damaging workpiece by pressure.
Beneficial effect: this fixture can facilitate, be clamped by selector fork securely, so that two surfaces in milling selector fork two fork-shaped portions while of milling cutter, such working (machining) efficiency is exactly the twice of traditional single-sided process mode, thus significantly reduce manufacturing cost, and this clamp structure is simple, easy to use, lower to the skill set requirements of work.
Accompanying drawing explanation
Fig. 1 is front view of the present invention;
Fig. 2 is the right view of Fig. 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
As shown in Figure 1, 2, a kind of hydraulic pressure milling fixture, is formed primarily of base 1, gripper shoe 2, back-up block 3, locating dowel 4, cylinder 5, cushion block 6, oil cylinder fixed head 7 and lever type hydraulic cylinder 8.Wherein, the end face of base 1 is fixed with one piece of gripper shoe 2, this gripper shoe 2 forms T-type structure with base 1.And, the right side of gripper shoe 2 is provided with the semicircle cutter relieving breach 2a of an opening towards the right side, this semicircle cutter relieving breach 2a runs through the front and rear panel face of gripper shoe 2, and the effect of semicircle cutter relieving breach 2a is stepped down to milling cutter, so that two surfaces of milling cutter simultaneously milling selector fork two forks.
The front face of described gripper shoe 2 is installed with a back-up block 3 and a locating dowel 4, and wherein locating dowel 4 is vertical with gripper shoe 2, and near the closing end of described semicircle cutter relieving breach 2a, and with the center line of semicircle cutter relieving breach 2a on same straight line.In the present case, locating dowel 4 is syllogic multidiameter structure, and the middle part of this locating dowel 4 is comparatively large, and two sections of front and back are less, and the installing hole tight fit in path section below and described gripper shoe 2.
