Abstract
A front end camshaft bore grinding device of a cylindrical grinding machine comprises a cylindrical grinding machine, a bore grinding tool, a fastening bolt, a dial gauge, a carriage, a camshaft, a central rack, a grinding wheel and a grinding machine body, wherein the dial gauge of the cylindrical grinding machine is sequentially connected with the bore grinding tool, the camshaft and the central rack, the camshaft is provided with the carriage at one end and with the central rack at the other end, and the carriage and the central rack are installed on the grinding machine body. Through the front end camshaft bore grinding device, spline cylindrical bouncing value decreases to 0.01 millimeter from 0.10 millimeter. A structure of double U-shaped grooves in opposite directions facilitating installation of clamps. The front end camshaft bore grinding device greatly reduces labor intensity and improves production efficiency. The design reference, measurement reference and processing reference of the front end camshaft during a grinding process are identical. The error of clamping installation is small. The utility model is widely used in processing bores of front end camshafts of cylindrical grinding machines.
Description
One, technical field
The utility model relates to the process equipment of engine leading portion camshaft endoporus, aperture apparatus in particularly a kind of cylindrical grinder grinding leading portion camshaft.
Two, background technology
Camshaft is the critical component of engine, and 190 gas engine camshafts belong to elongate articles, and at present, the grinding of endoporus on traditional slender axles is that the end with axle clamps cylindrical at grinding machine headstock place with chuck, and the other end is installed on 3 supports and finishes.This Apparatus and method for exists following shortcoming or deficiency: 1. because the positioning and clamping errors at scroll chuck and grinding machine spindle headstock place makes beating of this place become big, thereby cause after the grinding interior axially bored line with spool center line not on same straight line; 2. since the clamping of camshaft leading portion grinding endoporus operation chuck be the spline cylindrical, and after the leading portion inner hole grinding is finished, also will attach together, thereby the spline cylindrical is beated become big (the spline cylindrical finish grindes to finish size) before the grinding endoporus when causing the check of whole camshaft with back segment; 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 purpose of this utility model provides aperture apparatus in a kind of cylindrical grinder grinding leading portion camshaft, the inner hole grinding frock adopts the dual U-shaped open slot to connect with the grinding machine headstock, realize the structure of transmission of power, the shortcoming or the deficiency that overcome effectively or avoid existing in the above-mentioned prior art.
Aperture apparatus in the cylindrical grinder grinding leading portion camshaft described in the utility model comprises cylindrical grinder, inner hole grinding frock, fastening bolt, dial gauge, carriage, camshaft, centre frame, emery wheel and grinding machine body.The dial of described cylindrical grinder is connected with inner hole grinding frock, camshaft and centre frame in turn, and an end of camshaft is equipped with carriage, and the other end is equipped with centre frame, and carriage and centre frame are installed on the lathe bed.
Wherein, the camshaft end on the described centre frame contacts with emery wheel.Described carriage upper end is equipped with dial gauge.Described inner hole grinding frock is the tubular body structure that an end is provided with linking arm, and its tubular body is provided with spiral shell mosquito in M52 * 1.5 that are meshed with the camshaft end.The both sides of the connection front end linking arm of described inner hole grinding frock are for respectively being provided with the structure of the opposite U-shaped open slot of direction.Described inner hole grinding frock is fixed by fastening bolt and driver chuck.Described camshaft inner hole grinding frock adopts M52 * 1.5 internal threads to connect with the leading portion camshaft, axially strains with camshaft 7.
The utility model is compared with original technology and is had following advantage:
1, spline cylindrical jitter values can be reduced in 0.01 millimeter by original 0.10 millimeter.
2, can realize that camshaft attaches together back peach shape basic circle jitter values and the single hop parameter value is strict identical.
3, adopt opposite two " U " type groove structures of direction, convenient mounting and clamping alleviates labor intensity of operating personnel and production efficiency greatly.
4, the utility model adopts the 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.
5, the grinding machine headstock is top closely to be contacted with camshaft leading portion centre bore owing to adopting, and guarantees the coincidence of grinding convexity wheel shaft leading portion design basis, measuring basis, machining benchmark, and reduces caused clamping error in the camshaft clamping process greatly.
