Rocker arm chamber cap is a vitals of automobile engine, in processing process, ensure that the end face of Rocker arm chamber cap has good flatness, to ensure that it can perfectly be assembled in the middle of engine, products quality guarantee.The special-shaped end face operation of existing Rocker arm chamber cap is normally at the enterprising line operate of horizontal milling machine, by frock clamp milling flat in sleeping milling, but due to tool structure be the cavity that four perisporiums are set, Rocker arm chamber cap is put into wherein, locking member again by cavity arm is arranged is locked outside Rocker arm chamber cap, because Rocker arm chamber cap mostly is aluminium casting, so have certain internal stress at interiors of products, because the product cavity degree of depth is dark, wall is thin again, so easily cause deformation of products and vibration man-hour adding, to such an extent as to product plane degree can not effectively be ensured.
Therefore, need to improve existing Rocker arm chamber cap processing tool, make it effectively can position compression to Rocker arm chamber cap when carrying out lathe process to Rocker arm chamber cap, and in maximum magnitude, avoid the generation of wall is thin caused because the product cavity degree of depth is dark deformation of products and flutter phenomenon, ensure the flatness of product, thus products quality guarantee.
Utility model content
In view of this, the utility model provides a kind of Rocker arm chamber cap lathe process positioning tool, effectively compression can be positioned to Rocker arm chamber cap when carrying out lathe process to Rocker arm chamber cap, and in maximum magnitude, avoid the generation of wall is thin caused because the product cavity degree of depth is dark deformation of products and flutter phenomenon, ensure the flatness of product, thus products quality guarantee.
Rocker arm chamber cap lathe process positioning tool of the present utility model, comprise the positioning disk that is connected with lathe spindle and be pressed against the location that described positioning disk carries out processing from Rocker arm chamber cap inside and support stop member, it is three-point fix structure that stop member is supported in location, three locating dowels comprising positioning seat and arrange along the even cloth of positioning seat circumference, positioning disk is provided with three location stops, three location stops and described three locating dowel one_to_one corresponding are arranged.
Further, positioning disk is also provided with three alignment pins of triangularity structural configuration, three pilot hole position one_to_one corresponding of three alignment pins and Rocker arm chamber cap are arranged, and each alignment pin is ladder column structure.
Further, positioning disk is also provided with into four elasticity auxiliary supports that four-corner structure is arranged, each elasticity auxiliary supports includes supporter and for the spring of supporter along positioning disk axial stretching, positioning disk is provided with auxiliary supports installing hole.
Further, positioning disk is provided with the fixing structure for being connected with lathe spindle.
Further, each locating dowel and Rocker arm chamber cap interior side contacts end are provided with the rubber contact for loss prevention.
Further, locating dowel and positioning disk are formed in one structure.
Further, location is connected with the flexible power set of tail stock by taper shank to stop member.
Further, outside Rocker arm chamber cap, three rubber rings for damping are also provided with near end face outer.
The beneficial effects of the utility model: Rocker arm chamber cap lathe process positioning tool of the present utility model, stop member is supported by the location of three-point fix structure, from inner side by Rocker arm chamber cap tightly against being pressed in positioning disk, each locating dowel one_to_one corresponding that location stop on positioning disk supports stop member with location is arranged, clamping deformation can be prevented, by above locate mode, effectively can avoid the generation of wall is thin caused because the product cavity degree of depth is dark deformation of products and flutter phenomenon, ensure the flatness of product, thus products quality guarantee.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described.
Fig. 1 is the utility model structural representation;
Fig. 2 is for supporting stop member from Figure 1A direction view in location;
Fig. 3 is that Rocker arm chamber cap is from Figure 1B direction view;
