Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, the detailed description of the invention of the present invention is further described.
As shown in Figure 1 and Figure 2, the present invention is a kind of bendable Digital Electronic Torque Wrench with numerical monitor, including ratchet head 1, attachment screw 8, boosting-rod 2, digital display device 3, handle 4, sensor 5, gauge device 6 and regulation wheel 5, Qi Zhongchuan Sensor 7 is discoid sensor, including relatively turnable fixed grid 7-1 and moving grid 7-2, gauge device 6 inside boosting-rod 2, Sensor 7 is built in boosting-rod 2 and is connected with gauge device 6, and regulation wheel 5 is connected with gauge device 6, turning of regulation wheel 5 Dynamic change acts on the pressure on gauge device 6 and produces relatively rotating of sensor 7 fixed grid 7-1 and moving grid 7-2, sensor 7 It is converted into corresponding torque value by relatively rotating, and is shown by digital display device 3.
The internal driving signal producing the sensor with fixed skew of sensor 7, and by the receiving signal demodulation of sensor Be converted into digital signal, be multiplied by the coefficient corresponding to gauge device moment of torsion, be converted into gauge device set torque value and show.
Gauge device includes anti-loose spot 6-9, stop piece 6-8, pushing ram 6-7, forward block 6-6, compression spring 6-5, pressure Block 6-4, unloads power contiguous block 6-3, unloads power block 6-1 and regulation screw 6-2, described anti-loose spot 6-9, stop piece 6-8, pushing ram 6-7, forward block 6-6, compression spring 6-5, pressure block 6-4, unload power contiguous block 6-3, unloads power block 6-1 and rotary shaft 6-10 depends on Secondary connection, unloads and has regulation screw 6-2 on power block 6-1.
Pressure block 6-4 is connected with bearing 6-15 by axle 6-14 between power contiguous block 6-3 with unloading, unload power contiguous block 6-3 with Unload and be connected with bearing 6-13 by axle 6-12 between power block 6-1, unload between power block 6-1 and rotary shaft 6-10 by bearing 6-11 It is connected, or described pressure block 6-4 is connected by axle between power contiguous block 6-3 with unloading, and unloads power contiguous block 6-3 and unloads power block 6-1 Between by axle be connected, unload power block 6-1 and be joined directly together with rotary shaft 6-10.
Hollow guard ring 9 is elastomeric material, is unloading between power head 6-1 and boosting-rod 2.
Pushing ram 6-7 is adjusted by regulation wheel 5, makes propelling head 6-6 be moved forward or rearward along boosting-rod axis direction, Thus compression spring 6-5 is adjusted, reach to regulate spanner and carry out the moment required for bending, while being adjusted, Have between the fixed grid 7-1 and moving grid 7-2 of sensor 7 and relatively rotate, regulated value is transmitted, right through digital display device 3 Numerical value is optimized process and shows.
When the moment applied on spanner reaches the moment set by spanner, unload power block 6-1 and pressure block 6-4 by the power of unloading Contiguous block 6-3 carries out bending, reaches to unload power purpose, and spanner then passes through the elastic force of compression spring 6-5 unloading power when not working Block 6-1, pressure block 6-4 recover with unloading power contiguous block 6-3 position.
Unload power block 6-1 and pressure block 6-4 when carrying out bending by unloading power contiguous block 6-3, unload power block 6-1 and boosting-rod 2 it Between have gap with ensure unload the power block 6-1 movement relative with boosting-rod 2, hollow guard ring 9 can ensure to unload when spanner does not work Between power block 6-1 and boosting-rod 2 very close to each other, also to hollow guard ring 9 being extruded during work, unload power block 6-1 simultaneously And it is the most very close to each other between boosting-rod 2.
