Embodiment Construction
[0015] The implementation of the present invention will be described in detail below in conjunction with the drawings and examples.
[0016] Such as figure 1 As shown, a grinding machine hydraulic tailstock tip axial force measuring device includes a tip 2, a tailstock body 3, a pressure sensor 6 and a measuring instrument 12, etc. The tip 2 can be replaced, and the front end of the tip 2 is used to tighten the workpiece 1. A sleeve piston 4 and a hydraulic cylinder 20 are arranged on the tailstock body 3 . Sleeve piston 4 is the main movement mechanism of this device, and its tail end is connected with back gland 8 by connecting screw.
[0017] The top 2 is located in the sleeve piston 4 and protrudes from its front end, the rear end of the top 2 is provided with a spring 5, the pressure sensor 6 is located between the spring 5 and the thrust bearing 7, and the thrust bearing 7 is located between the rear gland 8 and the pressure sensor 6 Between, the adjusting knob 10 is c...

A grinder hydraulic tailstock center axial force measuring device comprises a sleeving piston located on a tailstock body and a rear pressing cover. The center is located in the sleeving piston and extends out of the front end. The rear end of the center is provided with a spring. A pressure sensor is located between the spring and a pushing bearing located between the rear pressing cover and the pressure sensor. An adjusting knob penetrates the rear pressing cover and the pushing bearing to be connected to the pressure senor. By the aid of the grinder hydraulic tailstock center axial force measuring device, the service life of the sensor is prolonged, reliability of a measuring system is improved, the problems that center axial force cannot be measured and recorded during clamping and processing a workpiece by a digital control grinder are solved, and the grinder center axial force can be measured accurately.
Description
technical field [0001] The invention relates to a top axial force measuring device of a grinding machine hydraulic tailstock. Background technique [0002] At present, for CNC grinding machines to process slender shaft workpieces, the supporting method is to install one end of the workpiece on the chuck of the machine headstock, and the other end on the top of the tailstock of the machine tool. The chuck and the top simultaneously exert force on the axial direction of the part. Pressure, so as to fix the workpiece in the axial direction, driven by the headstock motor, the chuck drives the workpiece to rotate around the axis. However, when clamping in this way, the size of the jacking force is mainly judged by the experience of the operator, and the data of the jacking force cannot be given accurately and intuitively, and the roundness and surface roughness of the workpiece will be affected if the jacking force is too large or too small. Influenced by the degree, high-precis...
