Description
Technical Field
The utility model relates to a carbon brush field specifically is a carbon brush elasticity testing arrangement.
Background
Carbon brushes, also called brushes, are widely used as a sliding contact in many electrical devices. The carbon brush is small in size, small in elastic force and high in requirement on testing accuracy, and the testing effect is not ideal due to the fact that the carbon brush is small in the process of testing the elasticity of the carbon brush in the conventional carbon brush elasticity testing device.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model discloses a carbon brush elasticity testing arrangement.
The technical scheme of the utility model is that: carbon brush elasticity testing arrangement, including the support frame, the support frame bottom is equipped with puts the thing platform, puts thing platform both sides and is equipped with clamping device, and the support frame top is equipped with the cylinder, and the output of cylinder is connected with the depression bar through the connecting block, and the connecting block bottom is connected with the fixed plate, and sliding connection has the test bar on the fixed plate, and the test bar top is connected with the pointer perpendicularly, and the pointer is located the calibrated scale, and the scale top of calibrated scale is equipped with the magnifying glass, and.
Further, clamping device is including being located the fixed block of putting thing platform both sides and fixing on the support frame, and the fixed block has inside clamping piece through spring coupling.
Further, the test bar is located the spout of fixed plate, and the spout of fixed plate is equipped with spacing piece and is used for restricting the test bar and toward falling outward, and test bar and pointer are the material that weight is lighter, and the bottom of test bar and the bottom of depression bar flush, are equipped with the interval between test bar and the clamp plate.
Further, the fixed plate is located on one side of the pressure rod.
Further, the cylinders are controlled by an external controller.
The utility model discloses an useful part: the utility model discloses simple structure amplifies the displacement of pointer through test bar and magnifying glass, can simply effectual elastic deformation size index of observing the carbon brush.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic structural view of the testing part of the present invention;
wherein: 1. the device comprises a support frame, 21, a storage table, 3, a clamping piece, 4, a spring, 5, a fixing block, 6, an air cylinder, 7, a connecting block, 8, a pressure rod, 9, a fixing plate, 10, a testing rod, 11, a pointer, 12, a dial, 13 and a magnifier.
Detailed Description
In order to deepen the understanding of the present invention, the following detailed description is given with reference to the accompanying drawings, which are only used for explaining the present invention and do not constitute a limitation to the protection scope of the present invention.
As shown in fig. 1-2, carbon brush elasticity testing arrangement, including support frame 1, support frame 1 bottom is equipped with puts thing platform 21, it is equipped with clamping device to put thing platform 21 both sides, support frame 1 top is equipped with cylinder 6, the output of cylinder 6 is connected with depression bar 8 through connecting block 7, connecting block 7 bottom is connected with fixed plate 9, fixed plate 9 is located one side of depression bar 8, sliding connection has test bar 10 on fixed plate 9, test bar 10 top is connected with pointer 11 perpendicularly, pointer 11 is located calibrated scale 12, the scale top of calibrated scale 12 is equipped with magnifying glass 13, magnifying glass 13 is located pointer 11 top, because elasticity is less, the displacement range that the pointer appears is less, can clearly see out the elastic deformation size through the magnifying glass.
Clamping device fixes fixed block 5 on support frame 1 including being located 2 both sides of putting the thing platform, and fixed block 5 is connected with inside clamping piece 3 through spring 4.
The test bar 10 is located the spout of fixed plate 9, and the spout of fixed plate is equipped with spacing piece and is used for restricting the test bar 10 and outwards falls, and test bar 10 and pointer are the material that weight is lighter, and the bottom of test bar and the bottom of depression bar flush, are equipped with the interval between test bar and the clamp plate.
The cylinders are controlled by an external controller.
Put the carbon brush that will carry out the elasticity test on putting the thing bench, then control the cylinder through the controller, extrude the carbon brush through the depression bar, when the carbon brush because elasticity undercut, the test bar of one side still stops on not being extrudeed the carbon brush surface to the displacement appears in the spout of fixed plate, pointer displacement upwards then, can see out elastic deformation size index through the magnifying glass on the pointer dish.
