Abstract
The utility model discloses a device that is used for outer wedge of grinding cover excircle, including grinding frock, clamping pad and clamp bolt, the last screw that is equipped with of clamp bolt, the one end of grinding frock sets up the heavy platform in circular cone location, keeps away from the one end that the circular cone location sinks the platform is equipped with the frock head, the frock is overhead to be equipped with and to treat that the outer wedge of processing overlaps the conical surface angle assorted conical surface. The utility model has the advantages that: can effectively process out high accuracy size and geometric tolerances's outer wedge cover, efficient, the yield is high.
Description
Technical field
The utility model Machining Technology field, particularly a kind of device for the outer cover of wedge cylindrical of grinding.
Background technology
Outer cover of wedge is that SPZ200 type is joined the part on car how, and SPZ200 type joins how shaping vehicle is China uses comparatively widely at presentA kind of railway large-scale maintenance machinery, it have to railway ballast how join, the effect such as shaping, cleaning, be that railway is newly-built, largeOne of indispensable supporting machinery in the big machinery equalization of repairing and keeping in repair.
Outer cover of wedge is arranged on the torque arm building block in the suspension rod shock mitigation system of axle gear box, and torque arm composition is damping, buffering systemCritical piece in system, and torque arm and outer cover of wedge are main stressed parts, are also A, category-B part. On torque arm composition, be provided withCover of wedge and outer cover of wedge assembly in the six pairs of rubber-metal assemblies and four pairs, all applied very high pretightning force, so for drawing when assemblingArm and outer cover of wedge, in use except being subject to pretightning force, being total to of powerful pulling force while being also subject to work, impulsive force, alternate loadSame-action. This just requires the part of outer cover of wedge in the time of processing and manufacturing, ensure high-precision size and Geometrical Tolerance Principle.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of device for the outer cover of wedge cylindrical of grinding, and this device can effectively addWork goes out the outer cover of wedge of high accuracy size and form and position tolerance.
In order to solve the problems of the technologies described above, the technical solution of the utility model is a kind of device for the outer cover of wedge cylindrical of grinding, bagDraw together grinding fixture, clamping pad and hold-down bolt; Described hold-down bolt is provided with screw; One end of described grinding fixture arranges circular coneLocation heavy stand, is provided with frock head away from one end of described circular cone location heavy stand, and described frock head is provided with and outer cover of wedge cone to be processedThe conical surface that face angle matches.
Further, described grinding fixture and described circular cone location heavy stand are one-body molded.
Further, on the heavy stand of described circular cone location, offer several connecting holes.
Further, the quantity of described connecting hole is 4.
Adopt technique scheme, can effectively process the outer cover of wedge of high accuracy size and form and position tolerance, efficiency is high, and yield rate is high.The excircle dimension accuracy class of outer cover of wedge reaches 6 grades, and the internal conical surface coning angle grade of tolerance reaches AT5, and internal conical surface to foreign roundConcentricity tolerance value reach 1 grade, surface roughness reaches 0.8.
Brief description of the drawings
Fig. 1 is the structural representation of front view of the present utility model;
Fig. 2 is the structural representation of left view of the present utility model.
In figure, 1-grinding fixture, 2-clamping pad, 3-hold-down bolt, 4-screw, the 5-conical surface, 6-circular cone location heavy stand, 7-connectsConnect hole.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described further. It should be noted that at this, for thisThe explanation of a little embodiments is used for helping to understand the utility model, but does not form restriction of the present utility model. In addition,In each embodiment of described the utility model, related technical characterictic just can be mutual as long as do not form conflict each otherCombination.
As shown in Figure 1-2, a kind of device for the outer cover of wedge cylindrical of grinding, comprises grinding fixture 1, clamping pad 2 and compresses spiral shellBolt 3; Hold-down bolt 3 is provided with screw 4; One end of grinding fixture 1 arranges circular cone location heavy stand 6, away from circular cone location heavy standOne end of 6 is provided with frock head, and frock head is provided with the conical surface 5 matching with outer cover of wedge conical surface angle to be processed.
The conical surface 5 is set, for locating outer cover of wedge internal conical surface.
Grinding fixture 1 is one-body molded with described circular cone location heavy stand 6.
On the heavy stand 6 of circular cone location, offer several connecting holes 7. Concrete, the quantity of connecting hole 7 is 4.
By the circular cone location heavy stand 6 and the connecting hole 7 that arrange, can better outer cover of wedge be positioned and is fixedly connected with, carryHigh manufacturing accuracy.
In use, clamping pad 2 is pushed down the end face of outer cover of wedge, and hold-down bolt 3 passes through screw 4 by solid to clamping pad 2 and outer cover of wedgeFix on grinding fixture 1. Circular cone location heavy stand 6 on grinding fixture 1 is fixedly connected with grinding machine spindle by ring flange, therebyComplete the grinding of external cover of wedge cylindrical.
Below by reference to the accompanying drawings embodiment of the present utility model is explained in detail, but the utility model is not limited to described realityExecute mode. For a person skilled in the art, in the situation that not departing from the utility model principle and spirit, real to theseThe mode of executing is carried out multiple variation, amendment, replacement and modification, still falls in protection domain of the present utility model.
