The device adopts a plane non-contact type coil spring as the standard body, the coil number pointer and the main shaft are connected together, and therefore, the test errors caused by that a heavy bob is used as a standard body and the standard body is deflected in the prior art are eliminated, and the test accuracy is raised under the condition without increasing the structural complexity degree. The utility model can be used for the test work of force moments of springs of various alarm clocks and timers and operating force moments of washers and electric fans.
Description
The utility model is a kind of clockwork spring moment instrument, and it belongs to the proving installation of alarm clock, timer clockwork spring moment, washing machine and electric fan timer operational torque.
At present, each alarm clock factory does not have the clockwork spring moment instrument.Clockwork spring and timer manufacturer are used to test the device of alarm clock and timer clockwork spring moment, washing machine and electric fan timer operational torque, no matter be of home make or import, its majority is to be converted by table scale, and it is that special the manufacturing forms that minority is only arranged, and does not have unified standard.Its ultimate principle be with weight as standard body, by rope, lever, steel band etc., give weight the transmission of torque of tested clockwork spring, reflect moment according to the deflection angle of weight.The forward and backward number of turns that is fixed on the barrel of clockwork spring outer end with range estimation reflects the number of turns that clockwork spring tightens, loosens.The shortcoming of this device is: the first, the angle of deflection of weight and moment values are not linear, and deflection angle is very little, for ease of showing moment values, then need to amplify by gear mechanism, so precision are low; The second, number of turns indication is not taken into account the deflection angle of standard body, thereby make the indication number of turns greater than the actual number of turns, and number of turns indication is according to range estimation and feel, therefore test is inaccurate, and alarm clock, the moment size of timer clockwork spring is meant its output torque when a certain specific number of turns, and this just causes the moment test inaccurate; Three, the moment of such device will be delivered on the standard weight by main shaft, disk, rope, lever, steel band etc., and moment indication is amplified by sector gear again, therefore, causes complex structure, volume is big, profile is not attractive in appearance.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and a kind of clockwork spring moment instrument accurate, simple in structure, that cost is lower of testing is provided.
Technical solution of the present utility model is: a kind of clockwork spring moment instrument, comprise a main shaft that is installed on the pedestal, the barrel that is installed on the pedestal of main shaft one end and links together and can rotate around main-shaft axis, the bar cassette holder, number of turns display disc, transmission gear, a gear that links to each other transmission gear is rotated with handwheel, a moment index dial and a moment pointer that links to each other with main shaft that connects with pedestal, stake is installed in the standard body and the standard body zeroing assembly of the main shaft other end in one, its special character is, this moment instrument also comprises a turns pointer that is connected with main shaft, and described standard body is a plane noncontact shape volute spring.
The untouchable volute spring in plane in the above-mentioned technical solution can be one or two.
Turns pointer in the above-mentioned technical solution can link to each other with main shaft by a hand rest together with the moment pointer.
Accompanying drawing has been described a preferred embodiment of the present utility model.
Fig. 1 is the outside drawing of this embodiment;
Fig. 2 is the axial front elevation after this embodiment removes shell and handwheel;
Fig. 3 is the sectional view of this embodiment along the A-A direction.
As follows with reference to accompanying drawing to being described in detail of embodiment:
This moment instrument comprises a pedestal 1; Main shaft 2 is installed on the pedestal 1 by two bearing levels; Be fixed with a tubular shaft 3 on the pedestal 1 of main shaft 2 one ends, by the bearing ring washer 4 between two bearings and the bearing bar cassette holder 5 be housed outside tubular shaft 3, this cassette holder can rotate around the axis of main shaft 2 in the outside of tubular shaft 3; The front end of bar cassette holder 5 is provided with a barrel 8, and the inner of the tested clockwork spring during use in the barrel 8 is fixing by the outer hook pin 6 of bar axle 7 that links to each other with main shaft and barrel respectively with the outer end; A number of turns display disc 9 is installed in the outside of bar cassette holder 5 and is fixed with a transmission gear 10, three spring latch locks are housed between bar cassette holder 5 and the number of turns display disc 9, display disc and bar cassette holder can be relatively rotated; Transmission gear 10 matches with the gear 22 that another links to each other with handwheel 23; On main shaft 2, be connected with a turns pointer 11 and a moment pointer 13 by a hand rest 12, turns pointer 11 and number of turns display disc 9 match in order to the indication number of turns, moment pointer 13 and be fixed on moment index dial 14 on the pedestal 1 together in order to indicate tested clockwork spring moment; Hand rest 12 and be fixed on the main shaft 2 with the form that is threaded by a fixing sleeve 15 with its corresponding balance stem 16; The other end at main shaft 2 is equipped with a standard body, this standard body is a untouchable volute spring 19 in plane, its interior stake links to each other with main shaft, stud 18 links to each other with the spiral gear 17 of standard body zeroing assembly, spiral gear 17 is installed on the supporting seat 20 of back, and it can do the running of sliding around back supporting seat 20; Spiral gear 17 and screw rod 21 match.
During work, first rotating screw bolt 21 rotates spiral gear 17 on the supporting seat 20 of back, and adjusting standard body by stud 18 is untouchable volute spring 19, makes the zero position of moment pointer 13 meridian seeking moment index dials 14.Tested clockwork spring is packed in the barrel 8, and its inner is fixing by bar axle 7, and the outer end is fixing by outer hook pin 6.Rotate handwheel 23, all rotate to make bar cassette holder 5, number of turns display disc 9 and barrel by gear 22 and transmitting gear 10, tighten simultaneously or loosen tested clockwork spring in the barrel.Rotate number of turns display disc zero set, rotate handwheel again, observe tightening of clockwork spring or loosen the number of turns by number of turns display disc and turns pointer, when arriving the position that needs, handwheel stops operating, from the position of moment pointer 13 meridian seeking moment index dials 14, just can read the moment numerical value of tested clockwork spring when this position.
The untouchable volute spring in plane among the above embodiment also can be two or more stacks.When moment is very big, also can adopt extension spring.
We can find out in conjunction with above embodiment, and the utility model has following advantage compared to existing technology:
1. adopting the untouchable volute spring in plane is standard body, and the measuring accuracy of moment instrument is improved.
2. do not adopt the gear amplification system, the mutual friction that this has not only reduced between the mechanism has improved measuring accuracy, and has simplified the structure of moment instrument, has reduced production cost.
3. number of turns pointer is directly linked together with main shaft, in the situation that does not increase moment instrument complex structure degree, eliminated the number of turns error in reading that causes because of standard body deflection, thereby greatly improved the measuring accuracy of moment of mainspring.
