Abstract
A plastic mandrel fixture for a gear hobbing machine mainly comprises a screw, a press plate, a plastic mandrel, a tightening screw, a sliding column, a base, a nut, a spacer, supporting circular rings and a hinge roll ball device. The plastic mandrel fixture for the gear hobbing machine is characterized in that the plastic mandrel, the press plate and the base are fixed in a fixture body through the screw and the nut, the spacer is arranged at the connecting position of the nut and the base, an upper supporting circular ring and a lower supporting circular ring are arranged below the press plate and used for supporting a workpiece, the tightening screw is arranged below the supporting circular rings, the sliding column is arranged between the tightening screw and the plastic mandrel, and the hinge roll ball device is arranged at the position symmetrical with the axis of the tightening screw and used for confirming the position, where a roughly-processed gear is located, on the mandrel. The plastic mandrel fixture for the gear hobbing machine has the advantages that assembly and disassembly are convenient, clamping force is even so that the workpiece can be firm, locating is more accurate, and an application range is wide.
Description
Technical field
The utility model relates to mechanical field, and what be specifically related to is a kind of gear-hobbing machine plastic mandrel anchor clamps.
Background technology
Jig is in metal cutting process, in order to determining the location of workpiece accurately, and with its firm grip, to accept the technological equipment of processing.In order to guarantee the crudy of workpiece, improve working (machining) efficiency, alleviate working strength of workers, give full play to and enlarge the processing performance of lathe.Because liquid plastics is incompressible, so existing grip device clamps to expand, the clamping mode of still feeling relieved is various, and craft precision is uneven, influences production efficiency.Publication number is the utility model of 201120385402.x, utilizes this characteristic, and ignored workpiece is determined accuracy and to adding man-hour to the stationarity of workpiece at shaft core position.
The utility model content
At the problems referred to above, the utility model proposes a kind of gear-hobbing machine plastic mandrel anchor clamps.
For realizing above purpose, by the following technical solutions: a kind of gear-hobbing machine mainly comprises screw with the plastic mandrel anchor clamps, platen, plastic mandrel, tighten screw, traveller, base, nut, pad, support annulus, the hinge roller unit, it is characterized in that, plastic mandrel and be fixed in the clamp body with screw and nut by platen and base, nut and base junction arrange a pad, the below of platen is provided with up and down, and two support annulus come supporting workpiece, the below of supporting annulus is provided with one and tightens screw, in the middle of tightening screw and plastic mandrel, establish a traveller, tighten screw axle center symmetric position and be provided with a hinge roller unit, be used for determining the position of gear on axle of roughing.
Described plastic mandrel comprises axle, liquid plastics, thin walled cylinder body, support column, it is characterized in that; thin walled cylinder body and axle are done no gap and joined work; liquid plastics is filled between thin walled cylinder body and the axle; axle and support cylinder are passed through a threaded screw in succession, and support column upper end one side is near liquid plastics.
Two of described support column respectively is provided with a projection ball, is diagonal positions.
The utility model has the advantages that: easy accessibility, clamping force evenly make workpiece firm, and it is more accurate, widely applicable to locate.
Description of drawings
Figure one is structural representation of the present utility model.
Among the figure 1, screw; 2, platen; 3, plastic mandrel; 4, thin walled cylinder body; 5, liquid plastics; 6, support column; 7 tighten screw; 8, traveller; 9, base; 10, nut, 11, pad; 12, projection ball; 13, support annulus; 14, hinge roller unit; 15, threaded screw; 16, axle.
The specific embodiment
Thin walled cylinder body (4) is done no gap with axle (16) and is joined work, liquid plastics (5) is filled between thin walled cylinder body (4) and the axle (16), axle (16) and support cylinder (6) are by a threaded screw (15) in succession, two of support column (6) respectively is provided with a projection ball (12), its upper end one side is formed a plastic mandrel (3) near liquid plastics (5).Plastic mandrel (3) and be fixed in the clamp body with screw (1) and nut (10) by platen (2) and base (9), nut (2) arranges a pad (11) with base (9) junction, the below of platen (2) is provided with up and down, and two support annulus (13) come supporting workpiece, the below of supporting annulus (13) is provided with one and tightens screw (7), tightening screw (7) and the middle traveller (8) of establishing of plastic mandrel (3), tighten screw (7) axle center symmetric position and be provided with a hinge roller unit (14), be used for determining the position of gear on axle of roughing.
After workpiece is fixed on and supports annulus (13), screw (1) by platen (2) with workpiece spindle to clamping, tightening screw (7) top by twisting passes through on support column (6) to power of traveller (8) output, the projection ball (12) of upper end acts on the liquid plastics (5) that is with thin walled cylinder body (4), because liquid plastics (5) has Incoercibility, an expansive force is provided, workpiece is clamped.And determine the position of gear on axle by hinge roller unit (4).
