Description
Technical field
The utility model is related to the fields of broaching tool, more particularly to using cylindrical pin with external thread that tool-broaching mechanism and shaft core is radially fixed
A kind of location structure of tool-broaching mechanism of position.
Background technology
Broaching tool is usually used in producing with processing circular hole, splined hole, keyway, plane and forming surface etc. in mass production in batch
Rate is very high.However the tool-broaching mechanism of the prior art, since main shaft is in running at high speed, tool-broaching mechanism has relatively radially with shaft core
Rotation, changes so as to cause spindle dynamic balance.
Invention content
The utility model aim is to provide a kind of location structure of tool-broaching mechanism, compact-sized, will using cylindrical pin with external thread
Tool-broaching mechanism and shaft core radial positioning, effectively keep spindle dynamic balance, solve the above technical problem.
In order to achieve the above technical purposes, reach above-mentioned technology requirement, technical solution is used by the utility model：
A kind of location structure of tool-broaching mechanism, including axle center, the pull rod being arranged inside axle center, and the pressing sleeve on pull rod surface is set；
The left end of pressing sleeve is provided with spring, and signal roundel is provided on the right side of pressing sleeve；It is characterized in that：It is symmetrically arranged on the surface in axle center
Groove A and groove B；Pressing sleeve surface is symmetrically arranged with through-hole A, and straight pin is both provided in through-hole B, the through-hole A, through-hole B,
The pull rod is connected and fixed with pressing sleeve by straight pin；The straight pin moves left and right in groove A and groove B；It is pressing
Set right side is provided with circumferential groove, and wear-resistant strip is provided in groove.
Preferably：The groove A and groove B is set as long waist type.
Preferably：The cylinder pin surface is provided with screw thread, and the through-hole A, through-hole B are threaded hole.
Preferably：The spring is butterfly spring.
Preferably：The circumferential groove is set as rectangle.
The beneficial effects of the utility model；A kind of location structure of tool-broaching mechanism, compact-sized, locating effect is apparent；With
Traditional structure is compared：It is symmetrical arranged fluted A and groove B on the surface in axle center；Pressing sleeve surface is symmetrically arranged with through-hole A, through-hole
Straight pin is both provided in B, the through-hole A, through-hole B, straight pin passes through groove and through-hole, and pull rod is connect admittedly with pressing sleeve
It is fixed, and moved left and right in groove A and groove B, it effectively eliminates and relatively radially rotates, reduce spindle vibration variation；On the pressing sleeve right side
The position that side is connected with shaft core is provided with wear-resistant strip, effectively reduces the friction between pressing sleeve and shaft core.To extend main shaft and
The service life of shaft core.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the sectional view of the utility model Fig. 1；
In figure：1. shaft core；2. pull rod；3. pressing sleeve；4. spring；5. signal roundel；6. groove A；7. groove B；8. through-hole A；
9. through-hole B；10. straight pin；11. circumferential groove；12. wear-resistant strip.
Specific implementation mode
In order to make the goal of the invention, technical solution and its advantageous effects of the utility model be more clear, below in conjunction with
The drawings and specific embodiments, the present invention will be further described in detail；
In attached drawing 1 and attached drawing 2：A kind of location structure of tool-broaching mechanism, including axle center 1, the drawing being arranged inside axle center
Bar 2, and the pressing sleeve 3 on 2 surface of pull rod is set；The left end of pressing sleeve 3 is provided with spring 4, and the right side of pressing sleeve 3 is provided with signal roundel 5；
It is characterized in that：It is symmetrical arranged fluted A6 and groove B7 on the surface in axle center 1；3 surface of pressing sleeve is symmetrically arranged with through-hole A8, leads to
Straight pin 10 is both provided in hole B9, the through-hole A8, through-hole B9, the pull rod 2 is connect with pressing sleeve 3 by straight pin 10
It is fixed；The straight pin 10 moves left and right in groove A6 and groove B7；Circumferential groove 11, groove are provided on the right side of pressing sleeve
Inside it is provided with wear-resistant strip 12；The groove A6 and groove B7 is set as long waist type；10 surface of straight pin is provided with spiral shell
Line, the through-hole A8, through-hole B9 are threaded hole；The spring 4 is butterfly spring；The circumferential groove 11 is set as
Rectangle.
The specific implementation of the utility model：By disk spring 4 loaded on pull rod 2, locked with pressing sleeve 3, then signal roundel 5 is filled
In on pull rod 2, then wear-resistant strip 12 is sleeved in the circumferential groove 11 on pressing sleeve 3, forms tool-broaching mechanism；By tool-broaching mechanism entirety
It injects in shaft core 1, circular broach mechanism, it is ensured that the through-hole A8 on pressing sleeve 3 is corresponding with the groove A6 in shaft core 1, through-hole B9 and axis
Groove B7 on core 1 is corresponded to, finally by cylindrical pin with external thread 10 on pressing sleeve 3.When cylinder is forged a knife, 2 meetings of pull rod are along straight line
Movement avoids and relative rotation occurs with shaft core 1.Spindle vibration variation is reduced, to extend the service life of main shaft and shaft core.
Above-described embodiment is only intended to clearly illustrate made by the utility model and describes, and not to the limit of embodiment
It is fixed, to those of ordinary skill in the art, other various forms of variations can also be made on the basis of the above description
