Equipment for testing post-forging cooling temperature curve of crankshaft forging

The utility model discloses a device for testing a post-forging cooling temperature curve of a crankshaft forging. The device is mainly composed of a temperature measuring instrument (1), a contact type high-temperature thermocouple (2) and a fixing tool (3). A temperature measuring probe (201) is arranged at one end of the contact type high-temperature thermocouple (2), and a socket (202) is arranged at the other end of the contact type high-temperature thermocouple (2); the socket (202) is connected with the temperature measuring instrument (1); the fixing tool (3) is mainly composed of an arc-shaped clamping part (301) and a long handle (302). A temperature measuring probe (201) of the contact type high-temperature thermocouple (2) is installed on the inner side face of the clamping part (301) of the fixing tool (3) in an attached mode. According to the utility model, the temperature change condition of the crankshaft forge piece in the whole post-forging cooling process from the post-forging high-temperat
