However, affected by the processing accuracy and assembly accuracy of the tool disc, especially the different degrees of tool wear, there will be differences between the actual processing stroke and the Z coordinate display data. Therefore, frequent measurements are required during the processing to determine the remaining processing amount of the part.
[0003] However, for a part with complex end faces to be processed, it is quite difficult to measure the processing distance using conventional measurement methods due to the influence of multiple end faces.

[0015] The utility model is further described below in conjunction with the accompanying drawings:
[0016] like Figure 1 , 2 As shown, a measuring tool for assisting in measuring the distance of a machined surface of a part comprises a mounting body 1, a dial indicator 2 and a movable probe 3. The rear end of the mounting body 1 can be temporarily mounted on a cutter head 6 of a machine tool, the dial indicator 2 is mounted on the mounting body 1, and the movable probe 3 is mounted on the front of the mounting body 1 and can slide forward and backward on the mounting body 1. The movable probe 3 has a measuring point cone tip 3011 for probing a machined surface 701 of a part 7, and the dial indicator 2011 faces forward and always keeps in contact with the movable probe 3 in front. The method of using the measuring tool is as follows: first, the rear end of the mounting body 1 of the measuring tool is fixed on the cutter head 6 of the machine tool, a reference end face 702 of the part 7 to be processed which is close to the cutter head 6 is selected, the cutter head 6 is pushed forward, so that the reference end face 702 presses the measuring point cone tip 3011, and then the movable probe 3 is retracted to compress the dial indicator 2011, so that the dial indicator reading is zeroed, and the Z coordinate reading a of the machine tool is recorded at this time. The measuring point cone tip 3011 is transferred to the processing surface 701 which is farther from the reference end surface 702, and the cutter head 6 is pushed forward so that the processing surface 701 presses the measuring point cone tip 3011, and then the movable probe 3 is retracted to compress the dial indicator 2 tip 2011, so that the dial indicator reading returns to zero, and the Z coordinate reading b of the machine tool is recorded at this time. At this time, the distance X between the two end surfaces can be calculated as: X=ba. It can be seen from the above usage method that the technical solution provided by the utility model can accurately and quickly measure the distance between the processing surface 701 of the processed part and the reference end surface 702, obtain the specific position of the processing surface 701, and thus determine the remaining amount to be processed.
[0017] Furthermore, the movable probe 3 has a probe rod 301 extending forward, and a measuring point cone tip 3011 is located at the front end of the probe rod 301. The measuring point cone tip 3011 always extends forward beyond the end of the front end of the mounting body 1, which is conducive to probing the complex end surface of the front part 7 of the mounting body 1. The probe rod 301 is parallel to the dial indicator tip 2011.
[0018] The front end of the mounting body 1 has a slide groove 101 , in which a slide block 4 capable of sliding forward and backward is arranged, and the movable probe 3 is fixed on the slide block 4 , so that the movable probe 3 can slide on the mounting body 1 .
[0019] A spring 5 is provided at the rear end of the slide block 4 in the chute 101, and the movable probe 3 can compress the spring 5 backward, and the spring 5 can also push the movable probe 3 forward. In this way, when the probe surface is changed from near to far, the movable probe can be automatically extended forward.
