Detailed description of the invention
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As shown in Figure 1, Figure 2, Figure 3 shows, the utility model comprises base 1, two bearings 8, single-action hydraulic cylinder 3, rotary body 5, rotary oil seal 2, push rod 9, and this device is used for processing cylinder barrel 7, and cylinder barrel 7 is placed in rotary body 5.The parts rotary body 5 of this device is notch cuttype cylinder, and the diameter at the two ends of rotary body 5 is unequal, and two bearings 8 are arranged on the two ends of base 1 inside and two bearings 8 are enclosed within on the outer wall of rotary body 5 less one end of diameter.One end that rotary body 5 diameters are less is stretched in base 1 and through the bearing 8 in base 1, the end, one end that rotary body 5 diameters are larger props up the end of base 1, rotary oil seal 2 is between two bearings 8 and be sleeved on the outer wall of rotary body 5 less one end of diameter, single-action hydraulic cylinder 3 is arranged on the inside of one end that rotary body 5 diameters are less, between rotary oil seal 2 and single-action hydraulic cylinder 3, is connected by oil circuit 10.One end of push rod 9 is connected with single-action hydraulic cylinder 3, and single-action hydraulic cylinder 3 drives push rod 9 to move, and the other end of push rod 9 is against on the outer wall of cylinder barrel 7 through rotary body 5 along the radial direction of rotary body 5, and push rod 9 clamps cylinder barrel 7.
As shown in Figure 1 and Figure 2, the quantity of single-action hydraulic cylinder 3 is four, and four single-action hydraulic cylinder 3 homogeneous reactors become to be distributed on rotary body 5, and single-action hydraulic cylinder is symmetrically installed with and is beneficial to the outer round surface that clamps cylinder barrel 7, makes cylinder barrel 7 outer round surface uniform stresseds.Each single-action hydraulic cylinder 3 is all connected with rotary oil seal 2 by independent oil circuit 10, does not alter mutually liquid between four single-action hydraulic cylinders 3, can work alone respectively.On the outside of the push rod 9 on each single-action hydraulic cylinder 3, be all arranged with spring 4, one end of spring 4 is connected with single-action hydraulic cylinder 3, and the other end of spring 4 is against or is connected to the side of rotary body 5 near cylinder barrel 7.Oil circuit 10 is connected with single-action hydraulic cylinder 3, and the fluid in oil circuit 10 provides power for single-action hydraulic cylinder 3, and single-action hydraulic cylinder 3 promotes push rod 9 withstands the outer round surface of cylinder barrel 7, and cylinder barrel 7 is clamped.On oil circuit 10, stop valve is installed, stop valve can be blocked the continuation input of fluid, and in the time that cylinder barrel 7 is clamped, spring 4 is in pressured state, the stop valve of installing on oil circuit 10 is opened the input of closing fluid, prevents that cylinder barrel 7 single-action hydraulic cylinder 3 after clamped from swinging because of unbalance stress.In the time that needs unclamp cylinder barrel 7, by the bounce pressure of spring 4, push rod 9 is resetted.
Its course of work is: first the cylinder barrel 7 of needs processing is placed into the endoporus the inside of the rotary body 5 of centre frame hydraulic swivel head, then positions by the endoporus that extraneous positioning chuck pawl 6 extend into the inner clamping cylinder barrels 7 of cylinder barrel 7.Positioning chuck pawl 6 is in clamping cylinder barrel 7, and push rod 9 clamps the outer round surface of cylinder barrel, exits positioning chuck pawl 6 carries out built-in mouthful processing to cylinder barrel 7 after the outer face surface of cylinder barrel 7 clamps.First clamp the endoporus wall of cylinder barrel 7 by positioning chuck pawl 6, then clamp built-in mouthful of outer round surface processing cylinder barrel of cylinder barrel 7, ensured the concentricity of built-in mouthful of cylinder barrel and inner hole of cylinder.After completing the built-in mouthful processing of cylinder barrel, push rod 9 resets and retracts, and takes off cylinder barrel 7 and complete built-in mouthful of processing of cylinder barrel 7.
The utility model is the cylindrical wall as positioning datum clamping cylinder barrel 7 by the first endoporus taking cylinder barrel 7, and then the built-in mouth of processing cylinder barrel 7, saved the first centre frame operation of processing on cylinder barrel outer round surface of locating with inner hole of cylinder, Zai Yi center chord position is the machining benchmark processing built-in hole of cylinder barrel.The utility model directly clamps the built-in mouth of the outer round surface processing cylinder barrel 7 of cylinder barrel 7 by centre frame hydraulic swivel head, saved manufacturing procedure, has improved production efficiency, has saved resource.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
