Description
Technical field
The utility model relates to power steering gear screw process technology, is specifically related to a kind of steering screw valve port slot machining frock.
Background technology
The steering of automobile comprises and turns to augmentor, and its principle is the power drive power assistance pump for steering relying on engine, increases the strength of pilot control front-wheel steer, to realize turning to flexibly with fluid power.
Turn to augmentor to comprise power steering stgear, power steering stgear comprises steering screw, is arranged with the valve port groove of multiple inclination in the hole of steering screw end etc.At present, when processing above-mentioned valve port groove, usually adopt and special scratch scouring machine processing, scratch scouring machine complex structure, cost is high, inapplicable for medium-sized and small enterprises.
Utility model content
The utility model provides a kind of structure simple, the steering screw valve port slot machining frock that cost is low.
This programme is as follows: steering screw valve port slot machining frock, comprise base, base is provided with the shoulder hole of level, the ladder inner sleeve for fixing steering screw is provided with in shoulder hole, ladder inner sleeve comprises large footpath section and path section, large footpath section is located radial through alignment pin, path section stretches out shoulder hole, equi-index plate is provided with at path section cylindrical, equi-index plate inner circle is evenly equipped with chute, equi-index plate and path section are located by flat key, and a side of equi-index plate and the end face of shoulder hole are adjacent to, and another side of equi-index plate is compressed by the nut be threaded with path section.
This programme operation principle is as follows: after steering screw loads ladder inner sleeve, locate radial through alignment pin anti-canting, the path section end of ladder inner sleeve is compressed by nut, then the alloy slotting cutter by being obliquely installed processes a valve port groove, when processing another valve port groove, exit alignment pin, screw out nut, equi-index plate shifts out along flat key, rotate ladder inner sleeve, the angle that ladder inner sleeve is rotated is consistent with the scale on equi-index plate, again equi-index plate is moved into, flat key is made to snap in the corresponding chute inner position of equi-index plate inner circle, then fastening nut, compress the end of ladder inner sleeve path section, alignment pin location steering screw, again process the valve port groove on this calibration, repeat above-mentioned action, until completion of processing.
After using this frock, without the need to adopting special scouring machine of scratching to process valve port groove, adopt existing lathe to coordinate this frock to process, this frock is compared to prior art, and structure is simple, and cost is low, easy to operate, practical.
Further, in order to ensure the stability of equi-index plate position, the utility model also comprises equi-index plate latch and latch frame, and latch frame is fixed by screws on the outer wall of shoulder hole, the uniform locating slot of equi-index plate cylindrical, equi-index plate latch can through the cylindrical of latch frame location equi-index plate.
Further, be provided with two positioning keys, be provided with T-slot bolt between two positioning keys in the bottom of base, positioning key is used for locating with lathe, and T-slot bolt is used for locking with lathe.
Further, in order to meet processing request, chute and locating slot are six.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: base 1, nut 2, equi-index plate latch 3, flat key 4, latch frame 5, screw 6, equi-index plate 7, ladder inner sleeve 8, steering screw 9, alignment pin 10, alloy slotting cutter 11, chuck 12, T-slot bolt 13, positioning key 14.
Embodiment is substantially as shown in Figure 1: comprise base 1, be provided with two positioning keys 14, be provided with T-slot bolt 13 between two positioning keys in the bottom of base 1.Base 1 is provided with the shoulder hole of level, is provided with the ladder inner sleeve 8 for fixing steering screw in shoulder hole, and ladder inner sleeve 8 comprises large footpath section and path section.
After steering screw 9 loads ladder inner sleeve 8, the steering screw 9 in the section of large footpath is the processing sections of steering screw, and this processing sections has endoporus, and by being fixed on the alloy slotting cutter 11 of the inclination on chuck 12, in endoporus, calibration processes six valve port grooves.At large footpath section cylindrical radial equipartition six locating holes, alignment pin 10 is through locating hole location ladder inner sleeve and steering screw.
Path section stretches out shoulder hole, be provided with equi-index plate 7 at path section cylindrical, uniform six locating slots of equi-index plate 7 cylindrical, equi-index plate latch 3 is arranged on latch frame 5, equi-index plate latch 3 can through the cylindrical of latch frame location equi-index plate 7, and latch frame 5 is fixed on the outer wall of shoulder hole by screw 6.Equi-index plate 7 inner circle is evenly equipped with six chutes, and equi-index plate and path section are located by flat key 4, and a side of equi-index plate 7 and the end face of shoulder hole are adjacent to, and another side of equi-index plate 7 is compressed by the nut 2 be threaded with path section.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
