Embodiment Construction
[0015] The technical solution in the present application embodiment will be described below in conjunction with the drawings in the present application embodiment.
[0016] Embodiment provides a method of generating grinding wheel track of the present application, such as figure 1 , The method comprising the steps of:
[0017] Step 102, acquiring the first hub first hub cloud point, and acquiring a first digital to analog hub corresponding point cloud;
[0018] Incidentally, the present application in the first embodiment of the hub of the hub may be any of a vehicle; In addition, the cloud point refers to the number of mold having a pre-established mathematical model point cloud corresponding to the hub. In one example, if you need to generate four kinds of vehicle wheel hub grinding track, the mathematical model may be implemented cloud point of the four kinds of the vehicle hub.
[0019] Step 104, based on the target and the first transformation matrix to obtain a second wheel ...

Embodiments of the present application provide a method and device for generating a hub grinding track; wherein, the method includes: acquiring a first hub point cloud of a first hub, and acquiring a digital-analog point cloud corresponding to the first hub; based on The target transformation matrix and the first hub point cloud obtain a second hub point cloud; wherein, the second hub point cloud matches the digital-analog point cloud; and a first projection corresponding to the second hub point cloud is created map, and create a second projection map corresponding to the digital-analog point cloud; determine the burr pixels of each rib window in the first hub based on the first projection map and the second projection map; based on the The coordinates of the burr pixels in the first projection map generate the burr grinding track of the hub rib window. Through the present application, the problem of low grinding efficiency and precision caused by manual grinding is solved in the prior art for grinding the wheel hub.
Description
Technical field [0001] The present application relates to a grinding wheel technology, and particularly relates to a method and apparatus for generating grinding wheel track. Background technique [0002] The rapid development of automobile wheels of the car produced a huge demand. Hub line, the hub many burr blank, the production process requires the burrs grinding removed and polished divided into coarse grinding and fine grinding, rough grinding is mainly polished hub ribs window edge visible apparent burrs for which issues, mainly the use of artificial polish polished manner. Manual polishing cost, high precision grinding, manual polishing is likely to cause the same type of grinding wheel inconsistent accuracy, doing difficult work for long periods of high focused drain polished portion may also occur. Inventive content [0003] Object of embodiments of the present application is to provide a method and apparatus for generating grinding wheel tracks, in order to solve the g...
