Abstract
The utility model provides a central hole four-jaw cartridge for processing large cylinder which is characterized in that the rear end face of the four-jaw cartridge provided with a circular rabbet is provided with a coupling and a clamping screw. The front end of the coupling is equipped with a circular boss cooperating with the circular rabbet on the rear end of the four-jaw cartridge, while the center of the rear end face of the coupling is mounted with a bushing with the top pointed cone. The utility model solving the universality problem of the tooling for processing and using of large cylinder reduces the cost of processing, and improves the working efficiency, in addition the utility model also has the advantages of simple structure and easy production.
Description
Technical field
The utility model relates to the technological equipment that a kind of mill type cylinder body is processed on lathe, especially a kind of mill type cylinder body processing centre bore chuck.
Background technology
At present domestic many hydraulic press manufacturer, processing to the mill type cylinder body comparatively bothers, its main cause is that the cylinder bottom of many mill type cylinder bodies has a macropore, the frock that has top taper hole when lathe carries out first step roughing (turning), just need be installed in the pointed cone hole of can't pinching therefore in the cylinder bottom macropore, because the big hole dimension difference of cylinder bottom, design the frock of different size, both time-consuming, increase cost again.
Summary of the invention
The utility model is used the centre bore chuck for the technical problem that exists in the solution known technology provides a kind of mill type cylinder body simple in structure, highly versatile to process.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of mill type cylinder body processing centre bore chuck, having the chuck of seam, the front end face that is installed in the chuck rear end face by the rear end has the terminal pad of the annular boss that matches with seam and the trip bolt that terminal pad is fixed on the chuck rear end is formed, also be shaped on centre bore on the described terminal pad rear end face, inlay the lining that has top taper hole in the centre bore.
Advantage and the good effect that the utlity model has are: owing to install the terminal pad that has top taper hole additional at the back side of chuck, but utilize the regulating action of chuck, can be installed in the cylinder bottom macropore of all size and finish first step roughing operation, significantly reduced frock design and production quantity, reduced cost, the utility model also has advantage simple in structure, that be easy to make in addition.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, the claw of chuck 4 front ends can be installed in the bottom outlet of cylinder body 5, the rear end face round seam 6 of chuck, rear end face at chuck is equipped with terminal pad 2 and trip bolt 3, is shaped on the round boss 7 that matches with the circular seam in chuck rear end on the front end face of terminal pad.Inlay the lining 1 that has top taper hole 8 at terminal pad rear end face center, so that the top is stuck on tail stock top.
Using method:
At first chuck claw of the present utility model is installed in the cylinder body bottom outlet, the utility model and cylinder body are become one, and then with the cylinder body front-loading on the chuck of lathe spindle, tail stock top withstands in the top taper hole of the utility model terminal pad, finishes being installed of cylinder body.
