Abstract
The utility model discloses a locking mechanism between an external spline guide rail and a cutter rack main shaft. The locking mechanism comprises an external spline guide rail and a cutter rack main shaft, wherein a conical hole is arranged on the right end of the external spline guide rail, and a plurality of positioning grooves are arranged on the right end face of the external spline guide rail. A conical body is arranged on the left end of the cutter rack main shaft, and a positioning pin is arranged on a cutter shaft connection face of the cutter rack main shaft. The conical body of the cutter rack main shaft extends into the conical hole of the external spline guide rail. The positioning pin is directed at arbitrary one of the plurality of the positioning grooves of the external spline guide rail. The cutter rack main shaft is fixedly connected with the external spline guide rail through locking nuts. The locking mechanism between the external spline guide rail and the cutter rack main shaft can achieve combinational assembly of the cutter rack main shaft and the external spline guide rail without providing a flat spline groove on the conical hole of the external spline guide rail, guarantees integral straightness, is simple in mounting and convenient to adjust.
Description
Technical field
The utility model relates to a kind of locking mechanism, is specifically related to the locking mechanism between a kind of external splines guide rail and the tool spindle.
Background technique
Placement between existing external splines guide rail and the tool spindle is on the axle journal of tool spindle, to open 4 flat key grooves in the 360 degree scopes, in the conical bore of external splines guide rail, opens the flat key groove of a correspondence simultaneously.
This Placement though can adjust straightness accuracy, has but had a strong impact on the rigidity of tool spindle and external splines guide rail, is easy to cause fractureing of tool spindle in the using process.
Summary of the invention
The utility model technical problem to be solved provides the locking mechanism between a kind of external splines guide rail and the tool spindle, and it can guarantee the rigidity of tool spindle and external splines guide rail under the prerequisite that guarantees whole straightness accuracy.
For solving the problems of the technologies described above, the technical solution of the locking mechanism between the utility model external splines guide rail and the tool spindle is:
Comprise external splines guide rail, tool spindle; The right-hand member of external splines guide rail is provided with conical bore, and the right side of external splines guide rail is provided with a plurality of locating slots; The left end of tool spindle is provided with cone, and the cutter shaft conjunction plane of tool spindle is provided with a locating stud; The cone of tool spindle stretches in the conical bore of external splines guide rail, and locating stud is aimed at any in a plurality of locating slots of external splines guide rail; Tool spindle is fixedly connected with the external splines guide rail through locking nut.
Said a plurality of locating slot circumference uniform distribution on the right side.
The left end of said external splines guide rail is provided with straight hole, and conical bore is communicated with straight hole.
The degree of depth of said conical bore is greater than the degree of depth of straight hole.
The technique effect that the utility model can reach is:
External splines guide rail of the utility model and the locking mechanism between the tool spindle need not opened the combination multi pack that the flat key groove can be realized tool spindle and external splines guide rail on the conical bore of external splines guide rail, and guarantee its whole straightness accuracy.
The utility model is installed simple, and is easy to adjust.

Embodiment
As shown in Figure 1, the locking mechanism between the utility model external splines guide rail and the tool spindle comprises external splines guide rail 2, tool spindle 3;
Like Fig. 2, shown in Figure 3, the right-hand member of external splines guide rail 2 is provided with conical bore 6, and the left end of external splines guide rail 2 is provided with straight hole, and conical bore 6 is communicated with straight hole; The degree of depth of conical bore 6 (being axial dimension) is greater than the degree of depth of straight hole;
The right side of external splines guide rail 2 is provided with a plurality of locating slots 5, a plurality of locating slots 5 circumference uniform distribution on the right side;
Like Fig. 4, shown in Figure 5, the left end of tool spindle 3 is provided with cone 7, and the cutter shaft conjunction plane 8 of tool spindle 3 is provided with a locating stud 4;
The cone 7 of tool spindle 3 stretches in the conical bore 6 of external splines guide rail 2, makes locating stud 4 aim at any in a plurality of locating slots 5 of external splines guide rail 2, through locking nut 1 tool spindle 3 is fixedly connected with external splines guide rail 2.
When external splines guide rail 2 makes up multi packs with tool spindle 3; If when crooked (being that whole straightness accuracy is not good); Can unclamp locking nut 1; After tool spindle 3 rotated a certain angle with respect to external splines guide rail 2, locating stud 4 is cooperated, with other locating slots 5 of external splines guide rail 2 end faces if still do not correct the not good problem of whole straightness accuracy; Then can continue to change the locating slot 5 with locating stud 4 pairings again, it is that the straightness accuracy behind tool spindle 3 and the external splines guide rail 2 combination multi packs is protected that a locating slot 5 finally must be arranged in 360 degree scopes.
