Drive system thermal temperature rise test and compensation system

A drive system thermal temperature rise test and compensation system mounted on a machine tool, wherein the machine tool has a transmission device and the transmission device is used to drive a platform, a main shaft cooperated with the platform is provided thereon, further comprising:

• a sensing head provided with a base, wherein the base has an arbor and the arbor is used for combination with the main shaft, a bracket is provided on the base, an optical non-contact type sensor group is surroundingly provided on the bracket, and a sensing center is formed in the center of the sensor group;
• plural ball lens devices respectively having a fixed seat, wherein the plural fixed seats are intervally fixed on the platform, an extension rod is combined with each of the fixed seats, and a ball lens is provided on a free end of each of the extension rods;
• more than one temperature sensors respectively combined with the transmission device of the machine tool, wherein each of the temperature sensors are used to measure temperature and transmit temperature data externally;
• and
• a signal processor signally connected to the sensing head and used for receiving the temperature data measured by each of the temperature sensors, wherein after the machine tool drives the sensing head, by means of the transmission device, to sequentially record an original point coordinate for a center of each of the ball lens, the transmission device operates to enable the sensing head to cyclically and sequentially move to the original point coordinate of each of the ball lenses, so as to record a displacement error between the sensing center and the center of the ball lens in each position of the original point coordinate sensed by the sensing head, along with the temperature data of each of the temperature sensors in the signal processor and use same for compensation.
