Detailed description of the invention
This application provides a kind of rolling depression cutter, achieve the machining accuracy improving all-steel piston annular groove.
Below in conjunction with the accompanying drawing in the embodiment of the present application, carry out clear, complete description to the technical scheme in the embodiment of the present application, obviously, described embodiment is only some embodiments of the present application, instead of whole embodiments.Based on the embodiment of the application, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the application's protection.
The front view of the rolling depression cutter that Fig. 1 provides for the application; The side view of the rolling depression cutter that Fig. 2 provides for the application; The sectional view of the roll blade of the rolling depression cutter that Fig. 3 provides for the application.
A kind of rolling depression cutter that the application provides, comprise: rolling depression cutter body 6, rolling depression cutter body 6 is provided with insertion tube, insertion tube comprises first section and is positioned at first section rear portion and connected second section, first section internal diameter is greater than second section internal diameter, the hole slot 8 of that the sidewall of second section is provided with strip and consistent with second section direction pair of opposing, cutter holder bar 3, roll blade 1 is provided with in the insert cartridges of the front end of cutter holder bar 3, insert cartridges rear portion is provided with chuck, chuck diameter is greater than the diameter in the bar portion of cutter holder bar 3 rear end, the bar portion of the rear end of cutter holder bar 3 inserts second section, bar portion is socketed with spring 4, spring 4 two ends are resisted against chuck and first section end respectively, the afterbody in bar portion is provided with connecting through hole, the first bearing pin 5 had through connecting through hole is run through in a pair hole slot 8, the end of the first bearing pin 5 and hole slot 8 clamping, the gap for bar portion Elastic Sliding is provided with between the bottom of the afterbody in bar portion and second section.
In said structure, be communicated with first section of arranging and second section before and after insertion tube comprises, first section diameter is larger, so its base diameter is greater than second section, form a step, may be used for blocking bottom spring 4, cutter holder bar 3 inserts in second section of insertion tube, and be connected by the first bearing pin 5 with it, first bearing pin 5 end is connected to hole slot 8 outer wall, and there is gap cutter holder bar 3 rear end, because hole slot 8 is strips, first bearing pin 5 can slide in hole slot 8 again, and band movable knife rack bar 3 slides.Spring 4 inserts in first section of insertion tube, and by the bottom stage screens of chuck and first section, can be stressed when roll blade 1 roll extrusion annular groove, spring 4 plays to be supported and withstands the effect of roll blade 1, and spring 4 is stressed when deforming, and power is delivered to insert cartridges, then be delivered on cutter holder bar 3 by it, extruding cutter holder bar 3 retreats, and to adapt to withstand roll blade 1, roll blade 1 is worked.Owing to have employed this structure, can realize further processing with the annular groove of this rolling depression cutter to piston, improve the machining accuracy that annular groove is shaping.
It is promote annular groove yields and make ultra-poor products transfer the effective measures of full certified products to that the rolling depression cutter adopting the application to provide increases annular groove rolling step.The rolling depression cutter that the application provides is owing to adopting split-type structural, and cutter hub need not be dismantled repeatedly, only needs to dismantle wearing part, improves production efficiency; And this split-type structural is very simple, light, very easily manufactures.
In the application one specific embodiment, roll blade 1 is circular, the center is provided with centre bore, insert cartridges is provided with the clip slot of clamping roll blade 1, insert cartridges is provided with a pair pin-and-hole of through clip slot, the end and pin-and-hole clamping that have through the second bearing pin 2, second bearing pin 2 of centre bore is run through in a pair pin-and-hole.Owing to have employed this structure, roll blade 1 can roll extrusion, while rotate around second bearing pin 2 at its center, rolls as wheel on annular groove, improves the smooth degree of rolling depression cutter roll extrusion.
In the application one specific embodiment, the first bearing pin 5 end arranges the split pin 7 connected and fixed in hole slot 8.Use split pin 7 to connect and fix the first bearing pin 5 very practical, structure is simple, and cost is low.
In the application one specific embodiment, the second bearing pin 2 end is provided with the split pin 7 connected and fixed in pin-and-hole.Use split pin 7 to connect and fix the second bearing pin 2 very practical, structure is simple, and cost is low.
In the application one specific embodiment, the thickness of roll blade 1 is inwardly thinning gradually by outward flange.Because roll blade 1 have employed the thickness of gradual change, namely directly to carry out roll extrusion place thicker in outer, is convenient to it and contacts with annular groove, and radially-inwardly more and more thinner, can prevent the scraping of the two sides up and down annular groove of roll blade 1, damage annular groove.
In the application one specific embodiment, roll blade 1 upper surface and the thinning angle of inclination of lower surface ecto-entad thickness are 15 degree.Concrete, thinning angle of inclination is set to 15 degree, and this angle is selection optimum in engineering practice, thinning DeGrain very little, the thinning structural strength that can affect roll blade 1 too much.Thinning inclination angle is all feasible 10 degree to 20 degree these scopes, and upper and lower surface is preferably simultaneously thinning.
In this description, each embodiment adopts the mode of going forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually see.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the application.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from the spirit or scope of the application, can realize in other embodiments.Therefore, the application can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
