Selection and optimization of temperature measurement points for saw blade grinding machine

 

 

    In order to find out the temperature field of the gear grinding machine during long-term production and processing, a large-scale CNC forming gear grinding machine is taken as the research object. According to its structural characteristics and the temperature rise of the moving parts, 26 main heat-receiving parts of the machine tool are set. Temperature Sensor. Since the relative position error Δz of the grinding wheel and the workpiece along the machine tool coordinate Z direction during the forming grinding process only affects the position of the tooth surface on the circumference of the gear, it does not have any influence on the tooth surface itself. In addition, the influence of the position error of the grinding wheel and the workpiece axis along the X direction of the machine coordinate system on the machining accuracy of the gear is particularly obvious. Therefore, the respective laser displacement sensors A and B are respectively mounted at the radial positions of the detecting grinding wheel and the workpiece shaft, and the measured displacements are Δxw and Δxg, respectively.

 

    The gear grinding machine has complex structure and many heat sources. The interaction between the heat sources will cause the variable coupling relationship between the various temperature variables in the thermal error compensation model of the machine tool, thus reducing the accuracy and robustness of the compensation model. In this regard, according to the basic principle of fuzzy clustering method, the correlation between the machine tool temperature and the corresponding displacement variable is firstly analyzed, and the correlation coefficients between multiple temperature-displacement variables are classified into one class; then the correlation coefficient is selected from which the correlation coefficient is large. The temperature variable is represented by this class; at the end of Zui, each temperature variable is represented as a temperature variable group for the thermal error modeling of the gear grinding machine.

New technology for saw blade grinding machine

 

    With the rapid development of science and technology, more and more new technologies are applied to the design field of gear grinding products. International gear grinding machine products and manufacturing technology are constantly developing and perfecting. On the basis of high-speed, composite, intelligent and environmental protection technologies, through the combination of control technology, computer technology and information technology, Huaxia Mould Network said that in this environment, the products are constantly moving to high efficiency, high precision, flexibility and integration. Development and high reliability direction and the trend towards multi-spindle, multi-coordinate, composite machining and automation of complete equipment.

 

    In the process of gear grinding machine design, we should emphasize the effective use of resources and energy and the protection of the ecological environment, minimize the consumption of non-renewable resources, and save raw materials. From the perspective of the overall structure, the principle of simplification of the structure is often adopted, and the design is simplified as much as possible to reduce the number of unnecessary parts. In the process of designing the parts of the grinding machine, the principle of simplification of the structure is also adopted. In addition, the modular design should be gradually adopted in the design of the gear grinding machine to meet the needs of different users, easy to repair, disassemble and recycle the products, so that the resources can be used to a large extent and save resources.
