Background technology
At present, the used anchor clamps of workpiece are installed on lathe scroll chuck, chuck, top, floral disc, axle etc. are arranged.But, still there is one type revolving parts to lack practical positioning clamping device, need the design frock to process usually.Such part possesses following essential characteristic: 1. have higher required precision, have the axiality requirement between cylindrical and cylindrical, cylindrical and endoporus, endoporus and the endoporus, circle and (or) have the perpendicularity requirement between the axis in hole and the end face; 2. the position that lacks standard chuck clamping is owing to reasons such as the too thin easy deformation of out-of-shape, wall or retaining part be too short are fit to the position that the standard chuck clamps; 3. have to be fit to the position that axially clamps, suitable pressing plate or the bolt structure from axially compressing arranged, as cylindrical shoulder, endoporus shoulder, the screw that is uniformly distributed along the circumference or (with) structure such as unthreaded hole.The part that possesses these three features extensively exists with various forms.Though the turning clamp that has existed some to be used for this class part of clamping, its serviceability is all not ideal enough.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency that exists at above-mentioned prior art and a kind of special-shaped plate class accessory turning that is used for lathe positioning clamping device is provided, this clamping device is not only simple in structure, highly versatile, and also easy to use, the location is accurate, and clamping is quick.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: include a circular base plate, at an end of circular base plate adjustable centering machine and axial pressing device are set.
Press such scheme, described adjustable centering machine comprises the cam that is installed in circular base plate middle part and forms along the uniform elastic slide block pawl configuration of circular base plate end face; Described elastic slide block pawl has 3, and is uniform along the circular base plate end face, with 3 radial trajectories phase configuration of corresponding setting on the cam.
Press such scheme, described axial compression mechanism comprise the radial groove that is provided with along the circular base plate end face and with the slide block bolt of radial groove phase configuration, the end of thread of slide block bolt is furnished with nut and pressing plate.
The utility model is fixed on the chuck of lathe when using, by twisting adjustment cam, the elastic slide block pawl is expanded outwardly synchronously realize the centering of workpiece endoporus, or under the compression spring action, promote the elastic slide block pawl and inwardly shrink synchronously and realize excircle of workpiece centering, by pressing plate and slide block bolt workpiece is fixed on the disk from axial compression then.
The beneficial effects of the utility model are: (1) highly versatile, easy to use, the mode that adopts radial centering and axially clamp all can be carried out quick-clamping for aforesaid special-shaped disk-like accessory.(2) positioning accuracy height, clamping is reliable.(3) simple in structure, cost of manufacture is low, can reduce the use of special fixture, and applied range.
