Description
Technical field
The present invention relates to a kind of tailstock on Metal Cutting Machine Tool, particularly a kind of tailstock showing bearing force.
Background technology
The tailstock of existing lathe comprises pedestal, in pedestal, there is sleeve, by bearing, main shaft is installed in sleeve, is provided with top in the endoporus front portion of main shaft, rear threads is connected with screw mandrel, and screw mandrel keeps off the thrust bearing being provided with between platform and pedestal end plate and bearing axial force.Connect with driving mechanism in the rear box that the rear end of screw mandrel extend into pedestal rear end.Screw mandrel can be driven to rotate by driving mechanism, because the rotating spindle of screw mandrel can move axially, toply can to hold workpiece when stretching out.The size of top bearing force can not be measured and show to the tailstock of this structure, and operator can only control by rule of thumb, cannot according to the autotelic adjustment bearing force of the concrete condition of workpiece.
Summary of the invention
The object of this invention is to provide and a kind ofly can measure at any time and show the tailstock of top bearing force size, overcome the deficiencies in the prior art.
The tailstock showing bearing force of the present invention, comprise pedestal, be arranged on pedestal interior front top, be arranged on pedestal inside back with the top screw mandrel be connected, be provided with thrust bearing between the gear platform on screw mandrel and the end plate on pedestal; Force bearing ring and gasket ring is provided with successively between described thrust bearing and end plate, end plate is processed with the oilhole storing fluid, end plate is provided with the Pressure gauge be connected with oilhole, is provided with the oil groove be connected with oilhole in the side of end plate, the side just shutoff oil groove of gasket ring.
The tailstock showing bearing force of the present invention, wherein said force bearing ring is sleeved in installing ring, be bolted to connection between installing ring and end plate, be processed with load annular groove in the side of end plate, side and the described gasket ring of described installing ring are positioned at load annular groove.
The tailstock showing bearing force of the present invention, top bearing force passes to force bearing ring and gasket ring by thrust bearing, can deform after gasket ring is stressed, different according to its deflection of stressed size, can to the fluid pressurization in oilhole when being out of shape, manometric pointer is deflected, the size of bearing force can be understood by manometric reading at any time.The dynamometry of this tailstock and Presentation Function provide conveniently for operator, according to the size of the concrete condition adjustment bearing force of workpiece, can ensure that the machining accuracy of workpiece.

Detailed description of the invention
As shown in Figure 1: 1 is the pedestal of tailstock, is provided with sleeve 5 in the inner side of pedestal 1, is provided with main shaft 4 inside sleeve 5 by fore bearing 3, intermediate bearing 6, butterfly spring 7, rear bearing 8 etc.Have top 2 at the inside front ends of main shaft 4, sleeve 5 rear end is connected with nut seat 10, and nut seat 10 internal fixtion has screw and screw mandrel 9 to match.The rear end of screw mandrel 9 to extend in the rear box 14 that is connected with pedestal 1 rear end and screw mandrel driven wheel 15 is housed, and screw mandrel driven wheel 15 is connected with the handwheel 16 be located at outside rear box 14 by transmission mechanism.Screw mandrel 9 has gear platform 11, between gear platform 11 and the end plate 17 of pedestal 1 rear end, is provided with the thrust bearing 12 bearing axial force.Above-mentioned is prior art part, no longer describes in detail.
As shown in Fig. 1,2,3,5: screw mandrel 9 is set with successively force bearing ring 20 and gasket ring 18 between thrust bearing 12 and end plate 17, end plate 17 is processed with the oilhole 22 storing fluid 19, the Pressure gauge 13 be connected with oilhole 22 is installed by screwed pipe joint at end plate 17 upper side edge place, is processed with the oil groove 23 be connected with oilhole 22 at the leading flank of end plate 17.Wherein force bearing ring 20 is sleeved in installing ring 21, be bolted to connection between installing ring 21 and end plate 17, be processed with load annular groove 24 in the side of end plate 17, side and the gasket ring 18 of installing ring 21 are just positioned at load annular groove 24, gasket ring 18 side just shutoff oil groove 23.
As shown in Figure 4: be processed with the hydraulic fluid port be communicated with oilhole 22 in the side edge of end plate 17, this hydraulic fluid port has been threaded oil nozzle 27, the inner termination of oil nozzle 27 is provided with steel ball 26 and spring 25 for the endoporus of shutoff oil nozzle 27, is connected with plug 28 at the endoporus ends screw of oil nozzle 27.Unload plug 28, by pressure filling device to oiling liquid 19 in oilhole 22, steel ball 26 and spring 25 serve the effect of check valve, i.e. fluid 19 only import but no export herein, and fluid 19 also can be glycerine.
Rotate handwheel 16, transmission mechanism by rear box 14 inside drives screw mandrel 9 to rotate, thus drive top moving axially, the bearing force of top ejecting workpiece passes to force bearing ring 20 and gasket ring 18 by thrust bearing 12, can deform after gasket ring 18 is stressed, different according to its deflection of stressed size, can the fluid 19 in oilhole 22 be pressurizeed when being out of shape, the pointer of Pressure gauge 13 is deflected, the size of top bearing force can be understood by the reading of Pressure gauge 13 at any time.
