Abstract
The utility model relates to a machining tool and particularly discloses a thin-wall part broaching tool which comprises a ring-shaped upper sleeve and a ring-shaped lower sleeve. The upper sleeve and the lower sleeve are in a threaded connection, positioning flanges are respectively arranged on the inner side of the upper end of the upper sleeve and on the inner side of the lower end of the lower sleeve, the inner diameter of the upper sleeve and the lower sleeve is over 0.02 millimeter longer than the outer diameter of a to-be-machined thin-wall part, and spanner circular beads are respectively installed on the excircles of the upper sleeve and the lower sleeve. According to the thin-wall part broaching tool, thin-wall parts can be assembled into an assembly in a stacking mode, defect that assembling and clamping deformation of the thin-wall parts is easy to cause during a broaching process can be avoided, and in addition, and broaching efficiency can be greatly improved.
Description
Technical field
The utility model relates to a kind of machining frock, relates in particular to a kind of thin-walled parts and draws the pin processing tool.
Background technology
Thin-walled parts be in the machinery assembling common a kind of accessory, especially disk class part draw pin processing more general.If this type of part adopts single-piece work method, not only working (machining) efficiency is low, and because the thin-walled parts poor rigidity, and part is easily by the broaching distortion, and causes the defective that interior axially bored line can not be vertical with the part plane.Therefore be necessary to design a kind of special-purpose broaching tool of thin-walled parts, not only guarantee crudy but also can guarantee that processing improves working (machining) efficiency automatically.
The utility model content
The utility model is difficult to make up in groups the automatically difficult problem of processing for above-mentioned thin-walled parts in automatically drawing pin processing, provide a kind of thin-walled parts to draw the pin processing tool.It can repeatedly be dressed up thin-walled parts group and automatically process, to guarantee crudy and working (machining) efficiency.
Mentality of designing of the present utility model is the assembly that a plurality of thin wall components is formed together easy processing by tooling combination.The technical scheme that solves the problems of the technologies described above is as follows: a kind of thin-walled parts draws the pin processing tool, it is characterized in that, comprise and overlap on the annular and trap, described upper cover and trap between be threaded connection the locating flange that inboard, lower end inboard and that trap, described upper set upper side is respectively equipped with.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, described upper cover and the internal diameter of trapping are larger more than 0.02 millimeter than the external diameter of thin-walled parts to be processed.This matched in clearance can make thin-walled parts flexible clamping in this frock, can guarantee that again processing with one heart.
Further, described upper cover and the cylindrical of trapping are respectively equipped with the spanner shoulder.The spanner shoulder is set to be conducive to the upper and lower sleeve screw thread rotation and to fix.
The beneficial effects of the utility model are: repeatedly install to thin-walled parts in this frock, clamp by locating flange up and down and can make it form an assembly, because the thin-walled parts entire combination is fitted in and has increased together rigidity, the end face of frock has all been protruded at two ends in the axial direction behind the while parts fixation, therefore in the broaching process or the anchor clamps end contact of workpiece and lathe can not produce the extra distortion that is installed, in addition because the size after the assembly combination can be overlapped consistent size with the tooth of broaching machine, therefore can realize at broaching machine the automation processing of automatic loading/unloading, thereby greatly improved working (machining) efficiency, changed the state that original part can not be processed automatically.

The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining the utility model, is not be used to limiting scope of the present utility model.
Arrive shown in Figure 9 such as Fig. 1, a kind of thin-walled parts 5 draws the pin processing tool, it is characterized in that, comprises the upper cover 1 of annular and traps 2, described upper cover 1 and trapping is threaded connection between 2, the locating flange 4 that described upper cover 1 upper end is inboard and 2 the inboard, lower end of trapping is respectively equipped with.
Described upper cover 1 and 2 the internal diameter of trapping are larger more than 0.02 millimeter than the external diameter of thin-walled parts 5 to be processed.This matched in clearance can make thin-walled parts 5 flexible clamping in this frock, can guarantee that again processing with one heart.
Described upper cover 1 and 2 the cylindrical of trapping are respectively equipped with spanner shoulder 3.Spanner shoulder 3 is set to be conducive to the upper and lower sleeve screw thread rotation and to fix.
Two aspects of design Main Basis of the present utility model: one, the size of automatic machining line material road and thin wall component, in order to determining the appearance and size of anchor clamps optimum, and cover 1 and 2 the internal diameter size of trapping on the frock; They are two years old, the size of broaching machine frock clamp and thin wall component, in order to determine cover 1 on the frock and the size of the locating surface in 2 of trapping, guarantee that frock does not directly contact with broaching fixture in thin-walled parts 5 hole broaching processes, but oneself positions on broaching fixture by frock.As adopt broaching machine then the size after the assembly combination can with the tooth cover consistent size of broaching machine, two measures have specifically been taked: one, position by cover 1 on the frock and 2 the locating flange 4 of trapping, limit its axial free degree, they are two years old, by screwing power thin wall component is fixed in the frock clamp, guarantees its globality.
The above only is preferred embodiment of the present utility model, and is in order to limit the utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
