Abstract
The utility model discloses an assembling caliper type torque transducer which can carry out dynamic measurement for objects to be measured under the state of not breaking the original operating state. Dynamometer links of the assembling caliper type torque transducer are symmetrically installed on a right chuck, planes at two sides of the dynamometer link are pasted with semiconductor strain sheets to form an allelobrachial full-bridge circuit connected with two dynamometer links in parallel, and then the assembling caliper type torque transducer conveys signals to be measured through a slip ring. The utility model has the advantages of simple structure, convenient operation and high measuring precision, and is beneficial to popularization and application.
Description
The utility model relates to the field of torque-measuring apparatus, especially is directly installed on the torductor that carries out torque measurement on the measured workpiece.
Torductor is used very extensive in machine-building, power generation and communications and transportation.Can directly measure and need not to carry out on-site proving on measured workpiece, have only a kind of type vibration wire torque gauge at present, its transfer principle is non-linear, and the manufacturing and the assembly precision of some parts are higher, still be difficult for guaranteeing that therefore, its measuring accuracy is lower.The product of the same type that the band microprocessor is abroad arranged, though better performances, price is too high.In recent years, the torque gauge of photoelectric method and magnetoelectricity transfer principle has abroad appearred adopting, but not commercialization as yet.
The purpose of this utility model provides a kind of can directly the measurement and torductor---the formula that is installed torque sensor that measuring accuracy is higher on measured workpiece, to address the above problem.
The utility model is based on a kind of so new principle: two double circular chucks are being installed on two positions of fixed length on the measured workpiece, when workpiece is turned round, these two pairs of chucks produce a relative angular displacement, make the responsive part of elasticity that is clamped between them produce flexural deformation, on the appropriate location of responsive part tension of elasticity and pressurized, paste semiconductor gauge, strain is converted to resistance variations, adopts the doube bridge complementary circuit, signal is exported.
Solution of the present utility model is: the formula that is installed torque sensor is made up of dynamometer link (5), left chuck (1), right chuck (9), slip ring (11), semiconductor gauge etc., the end of two dynamometer links (5) is installed on the right chuck (9), their other end is clamped in the holding ring (3) of left chuck (1), in left side chuck (1), the right chuck (9) snap ring (7) is arranged all, semiconductor gauge sticks on the dynamometer link (5).
Below in conjunction with embodiment and accompanying drawing the utility model is described in detail.
Fig. 1 represent to be installed partial sectional view of formula torque sensor
Fig. 2 represents dynamometer link
Fig. 3 represents to paste on the dynamometer link synoptic diagram of semiconductor gauge
Fig. 4 represents snap ring
Fig. 5 represent to be installed circuit part of formula torque sensor
As shown in Figure 1; Right chuck (9) and left chuck (1) are the semicircle chuck of opposite opened, and each semicircle chuck all has two earrings, and earrings drills through the hole, and during use, available bolt is fastened on chuck on the measured workpiece.Place snap ring (7) in left side chuck (1) and the right chuck (9), the interior external diameter of snap ring (7) has several symmetrical boss, and snap ring (7) is divided into two part (see figure 4)s.With cementing agent dynamometer link (5) and fixed cover (6) are combined as a whole, two dynamometer links (5) are fixed on the right chuck (9), make its symmetry and be the semi-girder state by screw.Both sides, the middle part processing plane (see figure 2) of dynamometer link (5), on two side planes of dynamometer link (5), paste the semiconductor gauge (see figure 3), semiconductor gauge is connected into the equiarm full-bridge circuit, then with the equiarm full-bridge circuit of two dynamometer links (see figure 5) in parallel.Slip ring (11) on the slip ring seat (10) transports out measured signal simultaneously for bridge circuit provides operating voltage.The seam crossing of slip ring (11) adopts the mitered mode, to guarantee not produce additional jump signal.
The other end of dynamometer link (5) is clamped on the left chuck (1) with holding ring (3), adjusts the end play that bolt (2) can be adjusted dynamometer link (5).Protective jacket (6) is enclosed within on the dynamometer link (5), with the semiconductor gauge on the protection dynamometer link (5).
The diameter of snap ring (7) has different specifications, changes snap ring, just can measure the moment of torsion of the axle of the different diameters of axle.
The utility model adopts above-mentioned frame for movement and doube bridge complementary circuit, not only can eliminate the impact of temperature and element nonlinear measurement precision, but also can compensate because of the measure error that machine adds, perturbed force causes in installation and the use procedure. Therefore, have the advantages such as simple in structure, that certainty of measurement is high, and price is low, be suitable in medium and small enterprise, applying.
