Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Embodiment
A kind of number of coils measurement mechanism is as shown in Figure 1: comprise frame 1 and be fixedly installed in the constant magnetism low-speed synchronous motor 3 in frame 1 by motor mounting rack 2, the clutch end of constant magnetism low-speed synchronous motor 3 is connected with to be arranged in use in corresponding spring to be measured by shaft coupling 5 coaxial transmissions and installs axle 9 in 17, on shaft coupling 5, be also provided with for being connected with corresponding spring 17 coaxial transmissions to be measured and to the Spring Card assembling structure (not shown) of corresponding spring 17 transmitting torques to be measured, constant magnetism low-speed synchronous motor 3 can be driven and be installed axle 9 and corresponding spring to be measured 17 synchronously rotates by shaft coupling 5.Install the axially consistent with the length direction extension of frame 1 of axle 9, install axle 9 and rotate and be assemblied in frame 1 by mandrel frame 10 away from one end of shaft coupling 5.Frame 1 is provided with to detect and installs the testing agency that axle 9 and spring 17 to be measured turn over the number of turns, testing agency comprise welding be fixed on install axle 9 ends the cam with protruding top 11, with the detecting sensor of the corresponding setting of cam 11 and the electronic type counter being electrically connected to detecting sensor, all can contacting once with detecting sensor with the protruding top of often turning around in installing the rotation process of axle 9 of cam 11, detecting sensor is installed in frame 1 by sensor mount 12 and screw.Install in the other frame 1 of axle 9 and be also provided with guide direction and the directive slide track axially paralleling 8 that installs axle 9, the slidable fit that leads on directive slide track 8 has the travelling carriage 6 of block structure, it is the vernier head 7 of copper schistose texture that the side of travelling carriage 6 is fixed with towards the structure that installs axle 9 directions extensions by screw, thereby vernier head 7 is provided with when corresponding spring 17 to be measured rotates and is slidably matched and drives vernier head 7 moving axially and spring to be measured 17 formation screws along spring 17 to be measured with the spring wire of spring to be measured 17 away from one end of travelling carriage 6, the auxiliary section of lead-screw drive mechanism, auxiliary section comprises for being sheathed in use the through hole (not shown) between adjacent two spring wires of corresponding spring to be measured 17, the hole wall of through hole and corresponding spring to be measured 17 form described screw, lead-screw drive mechanism.Digital display time relay 16 is also installed in frame 1 and controls the switch 15 that constant magnetism low-speed synchronous motor 3 moves.In other embodiments of the invention, constant magnetism low-speed synchronous motor 3 also can be replaced by other common electric machines such as other air motor, fluid motor, high-speed electric expreess locomotive, asynchronous machines; Certainly testing agency also can be replaced by miscellaneous equipments such as number of turns measuring instrument, scrambler, speed probe, angular transducers, and now cam 11 can not established; The structure of travelling carriage 6 can also be framed structure; Vernier head 7 can be also framed structure; The technical scheme of auxiliary section can also be the screw structure that covers at corresponding spring to be measured 14 peripheries and have the internal thread of joining with the volute spring silk kiss of spring 14 to be measured, and this screw structure can comprise a complete screw, also can comprise half screw or 1/4th screws.
Now take standard spring as the standard parameter of dispatching from the factory: the number of turns is 315 ± 3 circles, spring outer diameter 2.8mm, standard spring through being example for 2.2mm in spring carries out operation instruction to this number of coils measurement mechanism, for coordinating this standard spring, the through-hole diameter of auxiliary section is designed to 2mm, approximate in standard spring through size, be less than standard spring outside dimension.To install axle 9 passes in spring 17 to be measured, spring to be measured 17 and install axle 9 by screwing in the through hole on vernier head 7, vernier head 7 screws in spring 17 1 circles (for avoiding vernier head 7 not move axially along spring 17 to be measured smoothly) to be measured, then will install axle 9 and all be fixedly connected with shaft coupling 5 with spring 17 to be measured.Start constant magnetism low-speed synchronous motor 3, shaft coupling 5 drives install axle 9 and spring to be measured 17 synchronously rotates, constant magnetism low-speed synchronous motor 3 rotates a circle, spring 17 to be measured just rotates a circle, install axle 9 and also rotate a circle, corresponding vernier head 7 also can drive travelling carriage 6 to move the distance of a circle, disable motor when electronic type counter is shown as 314 under the spiral lift of spring to be measured, constant magnetism low-speed synchronous motor 3 has rotated 314 circles, and corresponding vernier head has also moved the axial distance of 314 circles.Then unclamp the fixing spring 17 to be measured of shaft coupling 5 and install the screw of axle 9, unclamp the fixedly screw of vernier head, taking-up installs axle 9 and in the position of vernier head 7, cuts off spring 17 to be measured, the standard spring that just to have obtained the number of turns be 315.
After measurement by 1 ~ 3 number of coils, can determine and measure a number of coils required time according to mean value, then by the 16 setting measurement times of digital display type relay.If the rotating speed of constant magnetism low-speed synchronous motor 3 is per minute 100, turn, the spring that the measuring spring number of turns is 315 needs the time to be about 3 minutes, and clamping, take-down time are about 2 ~ 3 minutes, and therefore, measuring a spring needs 5 ~ 6 minutes.This number of coils measurement mechanism takes mechanical automation to measure, and each survey crew can be monitored simultaneously, operate many measurement mechanisms, and efficiency increases substantially.
