Abstract
The pole milling hydraulically operated fixture that the utility model is designed, it is made up of clamp body, pressing plate, oil cylinder, bearing, locating piece, bearing pin.The upper end of described clamp body is provided with locating piece, oil cylinder and bearing are installed to the bilateral symmetry of described clamp body, described pressing plate is connected with bearing by bearing pin, and can rotate around bearing pin, described pressing plate one end and locating piece composition clamping structure, described oil cylinder is oblique to be arranged on clamp body, and the telescopic section of oil cylinder contacts with pressing plate, and both contacts site are the bottom of pressing plate away from locating piece one side.The feature of this structure is to rotate around bearing pin by hydraulic oil cylinder driving pressing plate, thereby clamps pole easily.
Description
Technical field
The utility model relates to a kind of pole milling hydraulically operated fixture, the pad gap bar milling hydraulically operated fixture using while relating in particular to turbine rotor assembling.
Background technology
Between blade on turbine rotor and blade root slot, there is certain gap, make blade keep fixing by pad gap bar.Pad gap bar is widely used in rotor assembling, and it has several different specifications.In conventional machining process, use bench vice to clamp one section of copper rod, and then mill the unnecessary cross section of copper rod, this processing mode is complex operation, inefficiency not only, and cannot ensure dimensional accuracy.In addition, owing to needing mill off copper rod to approach the cross section of half in processing, so very precisely guarantee crudy of the clamping position of milling fixture and clamping force direction.
Utility model content
The purpose of this utility model is the deficiency in order to solve above-mentioned technology and a kind of simple to operate, reliable clamping is provided, increases work efficiency and the pole milling hydraulically operated fixture of crudy greatly.
In order to achieve the above object, the pole milling hydraulically operated fixture that the utility model is designed, it is made up of clamp body, pressing plate, oil cylinder, bearing, locating piece, bearing pin.The upper end of described clamp body is provided with locating piece, oil cylinder and bearing are installed to the bilateral symmetry of described clamp body, described pressing plate is connected with bearing by bearing pin, and can rotate around bearing pin, described pressing plate one end and locating piece composition clamping structure, described oil cylinder is oblique to be arranged on clamp body, and the telescopic section of oil cylinder contacts with pressing plate, and both contacts site are the bottom of pressing plate away from locating piece one side.The feature of this structure is to rotate around bearing pin by hydraulic oil cylinder driving pressing plate, thereby clamps pole easily.
In order to improve the efficiency of processing, described oil cylinder and the quantity of pressing plate are eight, and the every side of clamp body has respectively four oil cylinders and pressing plate, and the oil circuit of eight oil cylinders is communicated with.Thereby the clamping space of fixture is increased greatly, the workpiece that the multiple workpiece of clamping, or clamping simultaneously are grown.While making clamping due to the oil circuit connection of eight oil cylinders, clamping power is evenly distributed simultaneously, thereby improves the precision of processing.
In order to adapt to various processing work, described locating piece is arranged on clamp body by draw-in groove, is demountable structure.By demountable structure, can make fixture be furnished with multiple locating pieces, to coordinate the pole of different diameters.
The pole milling hydraulically operated fixture that the utility model is designed, reasonable in design, be fixed on the workbench of vertical milling lathe, the start button of pressing on hydraulic power unit just can make the pole of placing on the synchronous compression locating piece of pressing plate, and one-pass can process two row's poles; In addition, just can be used to process the pole of different-diameter by changing locating piece, also can be according to the Design of length oil cylinder of clamp body and the quantity of pressing plate.This fixture has easy to use, and location is reliable, the feature that working (machining) efficiency is high.
Brief description of the drawings
Fig. 1 is the front view of the utility model pole milling hydraulically operated fixture.
Fig. 2 is the left view of the utility model pole milling hydraulically operated fixture.
Fig. 3 is the top view of the utility model pole milling hydraulically operated fixture.
In Fig. 1: 1 clamp body, 2 pressing plates, 3 oil cylinders, 4 bearing pins, 5 bearings, 6 locating pieces, 7 poles, 8 draw-in grooves.
Detailed description of the invention
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
Embodiment 1.
Referring to Fig. 1, Fig. 2, Fig. 3, the structural representation of hydraulically operated fixture for pole milling, comprises clamp body 1, pressing plate 2, oil cylinder 3, bearing pin 4, bearing 5, locating piece 6.Four oil cylinders 3 are equipped with respectively in clamp body 1 both sides, and the oilhole of clamp body 1 inside is each oil cylinder UNICOM, make the work that eight oil cylinders can be synchronous; Locating piece 6 is installed in clamp body 1 upper end, and pole to be processed is being placed in locating piece both sides; Pressing plate 2 is arranged on the both sides of clamp body 1 by bearing 5, every side all has four pressing plates, when oil cylinder work, backs down pressing plate lower end, drives pressing plate to compress the pole to be processed 7 on locating piece.
For replaceable parts, it is arranged on clamp body by draw-in groove locating piece 1, and its locating surface shape is to design according to the diameter of pole to be processed, and therefore, this hydraulically operated fixture can be used for processing the pole of different size, and simple to operate.In addition, the quantity of the total length of clamp body and two side guides can change according to the feed stroke of lathe, can make this hydraulically operated fixture make full use of the working ability of lathe, to improve working (machining) efficiency.
