Abstract
The utility model relates to a grinding wheel of a screw compressor rotor profile, which comprises a grinding wheel body. The center of the grinding wheel is provided with an installation hole; the radial outer edge of one end plane of the grinding wheel body inclines 35 to 60 degrees towards the center; and the radial outer edge of the other end plane of the grinding wheel body inclines 45 to 65 degrees towards the center. Because the two end planes of the grinding wheel body are set to be unsymmetrical two ends with an inclination angle according to the asymmetry of the rotor profile (tooth space), and therefore, the rotor profile grinded and processed by the utility model approximates to the actual rotor profile very much; the profile finishing workload is reduced; the finishing time is saved; and the processing efficiency is improved. The utility model can set the grinding wheels of different specifications according to different rotor profiles, and can be extensively applied to the grinding process of various screw compressor rotor profiles.
Description
Technical field
The utility model relates to a kind of emery wheel, particularly is primarily aimed at the molded lines of rotor of helical lobe compressor abrasive grinding wheel that the rotor helical-screw teeth groove carries out grinding about a kind of.
Background technology
Rotor of helical lobe compressor in the world at present adopts bilateral asymmetric profile of tooth, generally during grinding adopts the CBN forming grinding wheel or parallel grinding wheel is carried out grinding after according to the molded lines finishing.After adopting the parallel grinding wheel finishing for the bigger rotor of the facewidth, the time of carrying out grinding correction emery wheel again can increase more, has seriously influenced production efficiency.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind ofly can save the crushing time, improves the molded lines of rotor of helical lobe compressor abrasive grinding wheel of working (machining) efficiency.
For achieving the above object, the utility model is taked following technical scheme: a kind of molded lines of rotor of helical lobe compressor abrasive grinding wheel, it is characterized in that: it comprises the emery wheel body, described emery wheel body center has an installing hole, the radially outer edge of one end face of described emery wheel body is to centroclinal 35 °～60 ° angles, and the radially outer edge of described emery wheel body other end is to centroclinal 45 °～65 ° angles.
The utility model is owing to take above technical scheme, it has the following advantages: 1, the utility model is owing to the both ends of the surface with the emery wheel body, asymmetry according to molded lines of rotor (teeth groove), be arranged to asymmetric angle of inclination, two ends, therefore adopt the molded lines of rotor of the utility model grinding processing, can greatly reduce the trim amount of molded lines more near the actual molded lines of rotor.2, therefore the utility model can effectively save the finishing time because correction greatly reduces, and improves working (machining) efficiency.3, the utility model can be provided with the abrasive grinding wheel of plurality of specifications according to the difference of various molded lines of rotor.The utility model can be widely used in the grinding process of various molded lines of rotor of helical lobe compressor.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1, the utility model comprises an emery wheel body 1, the center of emery wheel body is provided with an installing hole 2, the radially outer edge of one end face of emery wheel body 1 is to centroclinal 35 °～60 ° angles, the radially outer edge of emery wheel body 1 other end is to centroclinal 45 °～65 ° angles, thus formation asymmetric emery wheel inclination angle, two ends.The utility model can set in advance the emery wheel body 1 of several angles of inclination different size according to the difference of molded lines of rotor of helical lobe compressor.
When the utility model uses, can select the emery wheel body 1 at the asymmetric angle of inclination of different size to be installed on the emery wheel drive unit according to the difference of the molded lines of rotor of helical lobe compressor of preprocessing.Through the finished rotor of helical lobe compressor of the utility model, the molded lines on it can be very near designing requirement, thereby has greatly reduced trim amount and finishing time to molded lines, has improved production efficiency.
In the foregoing description; main inventive point of the present utility model is according to the molded lines on the rotor of helical lobe compressor; design the asymmetric abrasive grinding wheel in angle of inclination, both sides; to reduce trim amount; therefore concrete angle of inclination can change, and these variations should not got rid of outside protection domain of the present utility model.
