Piezoelectric type device for measuring drilling force of deep hole

Abstract

The invention discloses a piezoelectric type device for measuring the drilling force of a deep hole, belonging to the technical field of sensing, observing and controlling, in particular a device fordetecting the drilling force and the torque moment of the deep hole in drilling process. The device comprises a base, an upper cover, a piezoelectric quartz sensor, a lead wire output plug, a lead wire, a gasket ring, a connecting bolt and a protection pad, wherein the piezoelectric quartz sensor clamped between the base and the upper cover is located in the right center of the device. The piezoelectric quartz sensor comprises a partition electrode, a complete electrode and a quartz wafer. The invention enhances sensitivity by combing a plurality of pieces of quartz crystals, only needs one sensor, and has the characteristics of simple structure, high sensitivity, favorable linearity and repetitiveness and high measurement precision. The piezoelectric type device for measuring the drillingforce of the deep hole can detect the drilling force and the torque moment in the deep hole processing in real time.

Description

technical field [0001] The invention belongs to the technical field of sensor measurement and control, and relates to a piezoelectric force measuring device for deep and small hole drilling, in particular to a detection device for drilling force and torque during deep and small hole drilling. Background technique [0002] The drilling process is a semi-closed process, especially for the drilling of deep and small holes. The cutting fluid cannot reach the cutting area, the chips are small, easy to accumulate, and the chip removal is difficult, forming a closed environment, causing the local temperature in the cutting area to rise rapidly, resulting in overheating and burning of the cutting edge, causing rapid wear of the drill bit. The usual solution is to regularly lift the drill to remove chips, which will seriously affect the production efficiency. In recent years, with the rapid development of automation, high efficiency and flexibility in the field of machining and the ...
