Abstract
The invention provides a method for grinding an inner hole of a front segment camshaft by an external grinding machine, which uses an external grinding machine and inner hole grinding tool. The method is characterized in that: a head holder driver chuck of the grinding machine and a head holder core clamper of the grinding machine are closely contacted with a central hole of a front segment of the camshaft to make design basis, measurement basis and processing basis of the front segment of the camshaft coincident. The method can make the design basis, measurement basis and processing basis of the front segment of the camshaft coincident, so that the circular run-out on a spline and the axiality of the ground inner hole of the front segment of the camshaft and the shaft are ensured strictly, and the peach-shaped basic circle run-out value strictly conforms to the single segment parameter value after the camshaft is assembled. Moreover, the method also has the characteristics of simple structure, easy operation, high working efficiency, and stable quality, and is widely applied to grinding processing of the inner hole of the front segment of the camshaft by the external grinding machine.
Description
One, technical field
The present invention relates to cylindrical grinder, particularly a kind of method of grinding inner hole of front segment camshaft by external grinding machine.
Two, background technology
Camshaft is the critical component of engine, and 190 gas engine camshafts belong to elongate articles, and the grinding of endoporus is that an end of axle is clamped cylindrical at grinding machine decoration frame place with chuck on traditional slender axles, and the other end is contained on 3 supports and finishes.Though this structure also can be finished the processing of endoporus, exist following shortcoming or deficiency simultaneously: 1. because the positioning and clamping errors at scroll chuck and grinding machine spindle headstock place, make beating of this place become big, thereby the center line that causes interior axially bored line and axle after the grinding is not on same straight line.2. since the clamping of camshaft leading portion grinding endoporus operation chuck be the spline cylindrical, and after the grinding of leading portion manhole is finished, also to attach together with back segment, thus cause whole next week wheel shaft when check spline place circle beat become big (spline place circle finish grindes to finish size) before the grinding endoporus.3. peach shape basic circle is beated change greatly near the endoporus place of attaching together, and has a strong impact on the quality and the result of use of camshaft.
Three, summary of the invention
The method that the purpose of this invention is to provide a kind of grinding inner hole of front segment camshaft by external grinding machine adopts hole tool in the grinding, connects with the grinding machine headstock, realizes transmission of power.Both overcome the spline cylindrical, the peach shape basic circle jitter values that cause in the camshaft leading portion inner hole grinding that exists in the above-mentioned prior art and become big.
The method of grinding inner hole of front segment camshaft by external grinding machine of the present invention, comprise and adopt cylindrical grinder and inner hole grinding frock, it is characterized in that adopting in that the grinding machine headstock driver chuck and the preceding grinding machine headstock are top closely contacting, make the coincidence of camshaft leading portion design basis, measuring basis, machining benchmark with camshaft leading portion centre bore.
Wherein, described camshaft inner hole grinding frock adopts the mode that connects of dual U-shaped groove and the grinding machine headstock.Described camshaft inner hole grinding frock adopts M52 * 1.5 internal threads to connect with the leading portion camshaft, with cam shaft to tension.Described camshaft inner hole grinding frock is the tubular body structure that an end is provided with linking arm, and its tubular body higher level is provided with spiral shell mosquito in M52 * 1.5.The both sides of described linking arm respectively are provided with a U-lag that opening direction is opposite.
The present invention has following advantage compared with prior art:
1, the present invention can reduce to spline cylindrical jitter values in 0.01 millimeter by original 0.10 millimeter.
2, the present invention can realize that camshaft attaches together back peach shape basic circle jitter values and the single hop parameter value is strict identical.
3, the present invention adopts double-U-shaped structure, and convenient mounting and clamping alleviates labor intensity of operating personnel greatly.
4, the present invention adopts M52 * 1.5 thread connection, and thread rotary orientation is subjected to force direction identical with the grinding of axle, guarantees that grinding endoporus processing convexity wheel shaft clamping is firm, safe and reliable.
Four, description of drawings
Fig. 1 is an inner hole grinding frock syndeton schematic diagram of the present invention
Fig. 2 is an inner hole grinding tool structure schematic diagram of the present invention
Fig. 3 is for pressing schematic side view shown in Figure 2
Five, the specific embodiment
Consult Fig. 1-Fig. 3, a kind of method of grinding inner hole of front segment camshaft by external grinding machine comprises and adopts cylindrical grinder and inner hole grinding frock.Employing closely contacts with camshaft 7 leading portion centre bores in that the grinding machine headstock 1, driver chuck 2 and the grinding machine headstock 1 are top, makes the coincidence of camshaft 7 leading portion design basises, measuring basis, machining benchmark.
Camshaft 7 inner hole grinding frocks 4 adopt the mode that connects of dual U-shaped grooves 41 and the grinding machine headstock 1.Camshaft 7 inner hole grinding frocks 4 adopt M52 * 1.5 internal threads to connect with the leading portion camshaft, axially strain with camshaft 7.Inner hole grinding frock 4 is the tubular body structure that an end is provided with linking arm, and its tubular body 42 is provided with spiral shell mosquito in M52 * 1.5.The both sides of linking arm respectively are provided with a U-lag 41 that opening direction is opposite.The grinding end of camshaft 7 is installed on the centre frame on the grinding machine body 10 8, contacts with emery wheel 9.Inner hole grinding frock 4 is fixed by fastening bolt 3 and driver chuck 2.Install carriage 6 on the grinding machine body 10 of inner hole grinding frock 4 front ends, dial gauge 5 is installed on it.
Claims (5)
1, a kind of method of grinding inner hole of front segment camshaft by external grinding machine, comprise and adopt cylindrical grinder and inner hole grinding frock, it is characterized in that adopting in that the grinding machine headstock driver chuck and the preceding grinding machine headstock are top closely contacting, make the coincidence of camshaft leading portion design basis, measuring basis, machining benchmark with camshaft leading portion centre bore.
