The effective monitoring distance N value of the position sensor 3 is larger than the M value + K value.
The effective monitoring distance N of the position sensor 3 is N value = M value + K value + (4 mm-5 mm).
The utility model discloses a theory of operation is:
in order to improve the use reliability of the clutch brake and improve the intelligence of equipment, the abrasion loss of a friction block of the clutch brake needs to be monitored in certain working conditions. The friction disc 2 has a reciprocating displacement action relative to the position sensor 3, and the value of the displacement gap between the clutch part friction block 1 and the brake part friction block 6 is monitored by the position sensor 3. We define the distance gap existing between the clutch part friction block 1 and the friction disc 2 as K value and the distance gap existing between the position sensor 3 and the friction disc 2 as M value. Generally, in order to improve the detection sensitivity, the M value should be as small as possible during installation and adjustment, and is generally 0.5-1 mm; when the position sensor 3 is selected, the effective detection distance of the position sensor is larger than the M + K value, and M + K + (4-5) mm can be taken in consideration of the abrasion loss of the two friction blocks.
When the crank press is in use, if the abrasion loss of the friction block is not abraded to a preset value, no matter the clutch brake is in a clutch state or a brake state, the M value or the N value is within an effective detection range of the position sensor 3, the position sensor 3 transmits a normal working signal, and the crank slide block mechanism can effectively move or stop. When the abrasion loss of the friction block exceeds the preset value, the M value or the N value also exceeds the effective detection range of the position sensor 3, at the moment, the position sensor 3 transmits a fault signal to the control program, the control program controls the press machine to be incapable of running, and at the moment, a worker can troubleshoot the fault, adjust the clearance value M or replace the friction block.
