Problems solved by technology

Due to the rough surface of the grinding wheel and generally non-metallic parts, the correct signal cannot be fed back or the probe will be worn. At present, it is difficult to accurately obtain the tooth profile data of the grinding wheel in a convenient way.
Therefore, the field of CNC gear grinding machines still cannot solve the problem of automatic alignment in a simple way, and it is difficult to realize continuous production
In the field of forming grinding, the commonly used centering device requires high precision but is easy to wear, and the overall machining accuracy is not satisfactory
At the same time, due to the different alignment methods, it is difficult to integrate the generation grinding and forming grinding in the same equipment

Embodiment 1

[0024] A gear grinding machine control method adopts a gear grinding machine including a workpiece spindle, a grinding wheel spindle and a dressing wheel spindle, and includes the following steps:

[0025] 1) Record the initial spatial position data of the dressing wheel installed on the main shaft of the dressing wheel;

[0026] 2) The dressing wheel is used to dress the grinding wheel mounted on the main shaft of the grinding wheel. When the dressing is completed, the dressing wheel meshes with the grinding wheel to obtain the space position data of the tooth groove or tooth profile of the grinding wheel ;

[0027] 3) Obtain the spatial position data of the tooth profile or tooth profile of the workpiece mounted on the workpiece spindle through detection, and adjust the grinding wheel according to the spatial position data of the tooth profile or tooth profile of the grinding wheel obtained in step 2) The position relative to the workpiece to be processed enables the tool setting ...

Embodiment 2

[0032] The steps are the same as in Embodiment 1, and this embodiment further defines them. The grinding wheel spindle in the gear grinding machine is parallel to the dressing wheel spindle, and the workpiece spindle is perpendicular to the grinding wheel spindle; a three-dimensional coordinate system is established with any point as the origin, so that the grinding wheel spindle is parallel or coincident with the Y axis, the workpiece The spindle is parallel or coincides with the Z axis, and the workpiece spindle and the grinding wheel spindle are both perpendicular to the X axis. The above content mainly defines the coordinates of the gear grinding machine, which belongs to the content known in the art.

[0033] In this embodiment, the grinding wheel is a worm grinding wheel;

[0034] In step 1), the initial spatial position data of the dressing wheel includes the y coordinate value of the center point of the dressing wheel. That is, step 1) is to record the y coordinate value ...

Embodiment 3

[0081] The same as in Example 1 or 2. Step 3) After the end, the workpiece to be processed is processed into a finished workpiece, and the accuracy of the finished workpiece is detected. When the accuracy does not meet the standard, go to step 1) again.

Abstract

The invention aims to provide a control method of a gear grinding machine, which is used for realizing automatic centering and continuous gear grinding. According to the technical scheme for fulfilling the purposes, the control method for the gear grinding machine which comprises a workpiece spindle, a grinding wheel spindle and a trimming wheel spindle comprises the following steps of: recording initial spatial position data of a trimming wheel which is installed on the trimming wheel spindle; trimming a grinding wheel on the grinding wheel spindle by the trimming wheel, and after the trimming is completed, engaging the trimming wheel with the grinding wheel, thus obtaining spatial position data on a tooth socket or a tooth profile of the grinding wheel; and performing detection to acquire spatial position data of a tooth socket or a tooth profile of a workpiece to be processed on the workpiece spindle, and adjusting the relative positions of the grinding wheel and the workpiece to be processed according to the spatial position data, obtained in the second step, on the tooth socket or the tooth profile of the grinding wheel, thus implementing tool setting between the workpiece to be processed and the grinding wheel.

Description

Technical field [0001] The invention relates to the manufacturing field of gear grinding machines. Background technique [0002] CNC gear grinding machines are widely used in the manufacture of gears and other parts. Among them, the CNC forming grinding wheel gear grinding machine is a precision CNC machine tool suitable for batch grinding of high-precision internal and external gears. Its processing principle is forming grinding, that is, the section of the shaped grinding wheel shaft is trimmed to the gear tooth groove Corresponding cross-sections are shaped and ground. The CNC generative grinding wheel gear grinding machine is another highly efficient precision CNC machine tool. It uses a worm grinding wheel and uses the generative principle to achieve high-efficiency machining. In the prior art, the design and manufacture of either the numerical control forming grinding wheel gear grinding machine and the numerical control generating grinding wheel gear grinding machine are...
