Description
Technical field
The utility model relates to a kind of mill spindle taper hole fixture, belongs to precision metal processing technical field of forging.
Background technology
Axle is one of typical part common in machining, and it is mainly used in the driving members such as supporting gear, belt wheel, cam and connecting rod in machinery, with transmitting torque.Different by version, axle can be divided into multidiameter, spindle taper, optical axis, hollow shaft, bent axle, camshaft, eccentric shaft and three bearing pins.
Main shaft with taper hole is one of common part in machining, and main shaft Morse's taper hole is called instrument circular cone, and tapering is close to 1: 20, and effect is the precision centering of transmitting torque and processing, detection; The high-precision requirement of certain spindle taper hole is the key technical indexes of this main shaft, and taper hole grinding is most important critical process in spindle processing; In order to the surface roughness of the axiality and the conical surface that will ensure taper hole and bearing position adopts grinding core hole after first cylindrical grinding, namely pull down plug after fine cylindrical, then refine taper hole, typical clamping method is: three-jaw folder main shaft right-hand member, upper centre frame supporting left end, grinding taper hole after centering; But this method adjustment centering difficulty is large, and the axiality index of taper hole still cannot ensure, affects outer round surface roughness.
Utility model content
The purpose of this utility model is: for the defect of prior art, propose a kind of mill spindle taper hole fixture, this clamp structure is simple, easy to process, it adopts rational auxiliary base transition, by location and the measurement of floating clamp and the several high accuracy mating surface of part, be convenient to adjust centering, grinding accuracy easily ensures, improve the accuracy of manufacture of main shaft, the every high precision technology index request of cone hole machine can be reached.
The technical scheme that the utility model adopts is: a kind of mill spindle taper hole fixture, comprise base, support and floating clamp, two supports are bolted on base, and two stands is provided with support axle journal, and the one end supporting axle journal is provided with floating clamp, floating clamp connects U-shaped frame, wherein be provided with bearing pin in U-shaped frame, and through U-shaped frame, the top of bearing pin is provided with steel ball, the both sides of bearing pin are provided with spring, and spring is fixed on bearing pin by connecting workpiece.
In the utility model: described U-shaped frame is provided with carbide alloy.
In the utility model: described support axle journal is provided with resilient sleeve near one end of floating clamp, avoid supporting axle journal and constantly wear and tear, thus improve wearability.
In the utility model: described support axle journal is fixed on two stands by fixed bolt.

Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1. base; 2. support; 3. resilient sleeve; 4. floating clamp; 5. steel ball; 6. spring; 7.U type frame; 8. bolt; 9. support axle journal; 10. bearing pin; 11. connect workpiece; 12. fixed bolts.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As seen from Figure 1, a kind of mill spindle taper hole fixture, comprises base 1, support 2 and floating clamp 4, two supports 2 and is fixed on base 1 by bolt 8, two stands 2 is provided with and supports axle journal 9, the one end supporting axle journal 9 is provided with floating clamp 4, and floating clamp 4 connects U-shaped frame 7, is wherein provided with bearing pin 10 in U-shaped frame 7, and through U-shaped frame 7, the top of bearing pin 10 is provided with steel ball 5, and the both sides of bearing pin 10 are provided with spring 6, and spring 6 is fixed on bearing pin 10 by connecting workpiece 11; Described U-shaped frame 7 is provided with carbide alloy; Described support axle journal 9 is provided with resilient sleeve 3 near one end of floating clamp 4, avoids supporting axle journal 9 and constantly weares and teares, thus improve wearability; Described support axle journal 9 is fixed on two stands 2 by fixed bolt 12.
During concrete enforcement, fixture is by base 1, support 2 and floating clamp 4 three part composition, two supports 4 are fixed on base 1, support axle journal 9 as Workpiece fixing datum level is placed on support 2, support axle journal 9 and connect U-shaped frame 7 by floating clamp 4, U-shaped frame 7 studs with carbide alloy, avoid supporting axle journal constantly to wear and tear, to improve wearability, support the high center that just in time should equal grinding head grinding wheel axle, the center of axle journal 9 high, otherwise taper hole bus will be made to be hyperbola, affect the contact precision of internal taper hole, and floating clamp 4 is contained in the taper hole of grinding machine spindle with taper shank, supporting axle journal 9 tail end inserts in resilient sleeve 3, with spring 6 by floating clamp 4 shell together with support axle journal 9 to Zola, the U-shaped frame 7 studding with carbide alloy is pressed to by steel ball 5, restriction supports the axial float of axle journal 9.Adopt this connecting mode, can ensure that the positioning precision supporting axle journal 9 is not by the impact of internal grinder spindle rotation error, also can reduce the impact of lathe vibration on crudy itself.
Above detailed description of the invention of the present utility model is described, but the utility model is not limited to above description.For a person skilled in the art, any equal amendment to the technical program and substitute be all among scope of the present utility model.Therefore, not departing from the equalization conversion and amendment done under spirit and scope of the present utility model, all should be encompassed in scope of the present utility model.
