C. The indexing clamping combination is clamped at the position close to one end of the corrugated roller, the chuck is used for clamping the end part of the corrugated roller under the condition that the corrugated roller is still kept in a natural state, and the chuck part of the coupling is kept coaxial with the corrugated roller.
D. And the coaxiality of the connecting seat of the coupling and the dividing disc is verified.
E. Directly over the corrugated roller grinding wheel and in the same plane with the grinding wheel face, a roller dresser is configured to perform tool setting at any time, and the position requirement is as follows: the linearity of the diamond roller is coincident with that of the grinding wheel.
In the corrugated roller tooth grinding method with the adaptive coaxial adjustment and the synchronous grinding wheel finishing, radial dynamic connection with a center body is respectively arranged between the compensation connector and the connecting seat and between the compensation connector and the chuck.
In the corrugated roller tooth grinding method with adaptive coaxial adjustment and synchronous grinding wheel trimming, preferably, the connecting seat and the chuck are arranged coaxially; and axial interlocking function is provided between the compensation connector and the connecting seat and between the compensation connector and the chuck.
In the corrugated roller tooth grinding method based on adaptive coaxial adjustment and synchronous grinding wheel dressing, preferably, the compensation connecting body is of a stepless slider structure, and only transmits the output power of the dividing disc and forms equal angular speed transmission with the chuck.

In the corrugated roller tooth grinding method with adaptive coaxial adjustment and synchronous grinding wheel dressing, preferably, the step amount of the roller dresser is provided by a grating ruler.
The technical scheme breaks through the traditional core adjustment means for machining the long-axis parts such as the corrugated roller, takes the workpiece as a starting point, utilizes the self weight characteristic of the corrugated roller, uses two V-shaped block brackets as two-point support on a workbench of a grinding machine, and adjusts the parallelism between the central line of the corrugated roller and the workbench and the straightness along the length direction of the rack in the simplest and easy-to-operate mode, namely, the corrugated roller is kept completely in a natural state. Then, the horizontal state (parallelism + straightness) of the corrugating rollers which is maintained by natural gravity is satisfied by an indexing nip combination.
Therefore, on the premise of ensuring that the dividing plate is connected with the grinding machine workbench in a hard mode, how to transmit the torque of the dividing plate to the corrugated roller is one of important problems to be solved by the scheme. The indexing clamping combination mainly comprises two parts, namely a coupling and an indexing disc, wherein the coupling is provided with a chuck with a centripetal clamping function, a connecting seat for clamping a corrugated roller and a connecting seat which is coaxially connected with the indexing disc at any time, a compensation connecting body is designed between the connecting seat and the chuck, and the compensation connecting body only transmits the output power of the indexing disc to the chuck, namely an intermediate body of force transmission, so that the indexing disc and the chuck move at an equal angular speed, and the coaxiality deviation between the chuck and the indexing disc is born by the compensation connecting body in a radial dynamic connection mode.
The radial dynamic connection of the centripetal body can enable the compensation connector to self-keep radial errors on the premise of transmitting torque, and the radial errors cannot affect the hard connection between the chuck and the corrugated roller or the coaxial hard connection between the connecting seat and the dividing disc, so that the equal amount of the rotation angle transmitted to the corrugated roller by the dividing disc every time is ensured.
In practical application, no matter the compensation connecting body is an elastic structure or a cross connector structure, no matter the compensation connecting body is a stepless slide block or a hydraulic and electromagnetic combination, the coaxiality requirement exists between the compensation connecting body and a chuck, which is a basic principle for manufacturing the compensation connecting body, so that the borne coaxiality deviation actual data are relatively small, and the coaxiality deviation phenomenon which is basically impossible to remove is solved on the premise of not influencing the force (work) transmission of the compensation connecting body.
Further, the scheme is that point-to-point diamond roller design is carried out on the existing grinding wheel fixing frame, namely a vertical beam, a roller dresser is designed in the same plane with the corrugated roller grinding wheel, and cutter setting is carried out at any time, so that the linearity of the diamond roller and the linearity of the grinding wheel are kept coincident. So as to realize the dressing of the grinding wheel by the diamond roller at any time point. In the process of continuous loss of the grinding wheel, the purpose of accurate repair can be achieved only by finely adjusting the diamond roller in the plane. The fine-tuning data is provided by the grating ruler, the detection range is large because the signal output by the displacement sensor of the grating ruler is digital pulse, the movement error of a compensation tool is determined by observing and tracking the feed error, the detection precision is high, and the response speed is high.
Compared with the prior art, the invention has the beneficial effects that: the design of the compensation connector solves the problems of large error and high adjustment difficulty of the traditional method for adjusting the coaxiality of the corrugated roller, simplifies the positioning procedure of the corrugated roller and improves the equal division precision of the circumferential tooth form; the point-to-point synchronous dressing is carried out on the grinding wheel which is easy to wear in gear grinding processing, the linearity of the formed grinding wheel is improved immediately, and the tool setting and moving time required by each grinding wheel dressing is reduced; the product quality is ensured, and the tooth-shaped grinding efficiency of the corrugated roller is improved.
