Abstract
The utility model is composed of a measuring mechanism for a standard spring, a measuring mechanism for a spring to be measured and a torque meter. A standard spring and a spring to be measured are arranged on a same shaft and are connected by a middle round disc and the shaft is arranged on a base. The other foot of the standard spring is also connected with the base and the other foot of the spring to be measured is connected with the operational round disc. The operational round disc is rotated and the spring to be measured drives the standard spring to rotate by the middle round disc. Because the rotation angle of the standard spring corresponds to a torque value indicated by a torque meter improved by an ohmmeter, the spring to be measured and the standard spring have different angles of torsion but an equal torque. Thus, when the spring to be measured is rotated to a certain required angle, a reading can be read from the torque meter. When having a different rotating direction (rightward rotation or leftward rotation), the spring to be measured can be arranged in a way of turning the head of the spring to be measured.
Description
The utility model relates to a kind of comparing measuring apparatus.
The measuring spring moment of torsion all was to utilize spring balance to measure earlier in the past, tried to achieve by series of processes such as calculating again, and during operating cost, work efficiency is low.Now pass through the domestic patent gazette of retrieval, and understand the relevant situation in market and learn also there is not this quasi-instrument of spring torque meter at present.
The purpose of this utility model is that manufacturing is a kind of simple in structure, easy to operate, and the wider spring torque meter of the scope of application, to adapt to the needs that China's low-voltage electrical apparatus and machinery manufacturing industry develop rapidly.
In order to achieve the above object, the utility model is by standard spring measuring mechanism, and tested measurements of springs mechanism and torquer three parts are formed.Standard spring measuring mechanism and tested measurements of springs mechanism are contained on the same axis, and standard spring and tested spring respectively have a pin with being connected on the cental element dish, and axle then passes the cental element dish and is fixed on the base; Another pin of standard spring also is fixed on the base, and another pin of tested spring is connected with the Operand dish.Rotating operation unit dish, tested spring promptly rotate measurement data together by the moving standard spring of cental element dribbling---and moment of torsion can be read from torque meter.
Earlier installing standard spring measuring mechanism on the base: the standard spring is enclosed within on the lug of cental element dish, with axle the cental element dish is contained on the base, and two pin one of spring connect cental element dish, and connect base.Slip ring resistor and annular protractor are contained on the base of the outer unit of spring, resistor and base insulation; Adorn sliding contact arm a---pointer again on the cental element dish, pointer keeps often contacting with resistor.When standard spring during in free state, (0 °) of pointer centering annular protractor.Respectively connect two binding posts of a lead from cental element dish and slip ring resistor connector lug again to ohmmeter (afterwards changing torque meter into).
Try to achieve actual torque value and the with it corresponding resistance value of standard spring when the various windup-degree by survey instrument such as spring balance and by calculating, ohmmeter is changed into torque meter.
The other end at axle installs movable pointer, sleeve pipe (when spring inside diameter is big), tested spring, Operand dish and set screw etc. again, tested spring one termination cental element dish, terminated operation unit dish, adjust the end play between tested spring and Operand dish, when tested spring is in free state, mobile movable pointer makes with (0 °) groove of the outer unit of Operand dish and aims at, and can measure.
Can make work efficiency improve more than 4 times during measure batch
Figure of description is the structural drawing of spring torque meter.
Accompanying drawing has been described embodiment of the present utility model.With reference to accompanying drawing, the 1st, base, slip ring resistor 14 is placed in the bottom tub, and both insulate with insulating material 15.Connector lug 17 on the resistor is connected with the binding post of lead 16 with ohmmeter (afterwards changing torque meter into) 11 from the downward protuberate basic unit of bottom land tapping.5 is the cental element dish, and standard spring 4 is enclosed within on its lug, and two pin of spring are connected with cental element dish and base respectively.The cental element dish is contained on the base with axle 13.Cental element dish and axle are done movingly, and both have certain end play.Certain axial and radial play is also arranged between standard spring and cental element dish and base.Lead 12 is from another binding post of cental element dish connecting resistance table.Movable contact arm---pointer 3 is contained on the cental element dish, keeps often contacting with resistor.When standard spring during in free state, (0 °) of pointer and annular protractor is aimed at, and at this moment the reading of ohmmeter also is (0).
Utilize survey instrument such as spring balance to calculate the actual torque of standard spring when various windup-degree, change corresponding with it resistance value into torque value, ohmmeter is changed into torque meter.
The other end at axle installs sleeve pipe (when tested spring inside diameter is big) 8, tested spring 7, movable pointer 6, the Operand dish, with set screw 10, tested spring one termination cental element dish, one terminated operation unit coils, and adjusts the end play of tested spring and Operand dish, and mobile movable pointer makes and outer first (0 °) the groove centering of Operand dish, rotating operation unit dish, tested spring promptly drives the cental element dish and the standard spring rotates together, though both anglecs of rotation vary in size, moment of torsion equates, so when tested spring is forwarded to a certain required angle, just can from torque meter, directly read its pairing moment of torsion.
When tested spring sense of rotation (dextrorotation or left-handed) not simultaneously, spring tune should be placed.
