Description
Technical Field
The utility model relates to a dielectric loss tester specifically discloses a dielectric loss tester sample fixed establishment.
Background
In the quality inspection of the enameled wire, the dielectric loss is an important detection item. The dielectric loss can reflect the curing degree of the enamelled wire paint film of the same variety. The curing degree of the enameled wire paint film is related to whether the performance of the enameled wire is changed during the storage period and the service life of the prepared winding. The dielectric loss detection can also detect whether the wire coating process is finally adapted to the solvent evaporation characteristic of the paint liquid and the reaction characteristic of the binder resin, thereby achieving the purposes of guiding production and adjusting the wire coating process.
However, in the process of measuring the dielectric loss of the enameled wire by using the enameled wire dielectric loss tester, because the change of each measured quantity to be measured is small, the slight shaking of the enameled wire in the measuring process may cause a large error to the measuring result; and the enameled wire sample needs to be continuously heated in the whole measuring process, and the heating uniformity of the enameled wire sample can also influence the measuring result.
For the above problems, chinese patent No.: 200920286805.1, patent name: the special sample holder for the enameled wire flat wire dielectric loss tester solves the problems in a certain degree; the test stand has the advantages that the test stand is firm and stable in fixing, the enameled wire is uniformly heated, and the error of dielectric loss measurement is reduced to a certain extent; however, the test frame is complex in pressing operation, and a sample is directly pressed and fixed, so that a surface paint layer is easily damaged by hard contact, and the accuracy of a test result is influenced.
SUMMERY OF THE UTILITY MODEL
The invention of the utility model aims to: the sample fixing mechanism of the dielectric loss tester is simple in structure, capable of achieving rapid fixing of a sample, and free of damage to a paint film on the surface of the sample due to elastic connection.
The utility model discloses a technical scheme be like:
the sample fixing mechanism of the dielectric loss tester comprises a fixed block and a movable block, wherein the movable block can move up and down relative to the fixed block to clamp a sample; the transmission rod is sleeved with a spring, the upper end of the spring is abutted to a baffle connected to the transmission rod, and the lower end of the spring is abutted to the movable block.
Further, the guide rod penetrates through the movable block longitudinally.
Furthermore, an insulating sleeve is arranged at the joint of the transmission rod and the movable block.
To sum up, owing to adopt above-mentioned technical scheme, the beneficial effects of the utility model are that:
the utility model has simple structure, and realizes the rapid clamping and fixing of the sample by pulling the wrench to drive the movable block to move up and down; the pressing of the sample is realized by pressing the movable block downwards by the elasticity of the spring, the sample is elastically clamped without damaging a surface paint film, and the accuracy of a test result can be ensured.

FIG. 1 is a structural diagram of the specimen clamping state of the present invention;
fig. 2 is a structural view of the unclamped state of the sample of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1-2, the sample fixing mechanism of the dielectric loss tester comprises a fixed block 1 and a movable block 2, wherein the movable block 2 can move up and down relative to the fixed block 1 to clamp a sample; the movable block 2 is connected with the lower end of the transmission rod 3, the upper end of the transmission rod 3 is connected with a wrench 4, and the wrench 4 is pulled left and right to drive the movable block 2 to move up and down; a spring 5 is sleeved on the transmission rod 3, the upper end of the spring 5 is abutted with a baffle 6 arranged on the transmission rod 3, and the lower end of the spring 5 is abutted with the movable block 2; when the movable block 2 is lifted by the upward movement of the transmission rod 3, the spring 5 is reset (as shown in figure 2), and when the spring 5 is compressed by the downward movement of the transmission rod 3, the spring 5 presses the movable block 2 to clamp a test sample (as shown in figure 1), and the paint film on the surface of the test sample is not damaged by elastic clamping.
The device also comprises a guide rod 7, wherein the guide rod 7 longitudinally penetrates through the movable block 2; the guide rod 7 can prevent the movable block 2 from deviating in the moving process, so that the detection result is influenced by uneven stress of the sample.
The connecting part of the transmission rod 3 and the movable block 2 is provided with an insulating sleeve to prevent conduction.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
