Description
Technical field
The utility model is related to a kind of carbon brush elasticity test devices, belong to technical field of electronic device test.
Background technology
Carbon brush is often used in electronic vehicle device, carbon brush is connect by torsional spring with electronic device, but the bullet of torsional spring
Power is not of uniform size, need to test the elastic force of torsional spring, i.e., test the elastic force of carbon brush, since carbon brush is small, elastic force
Also smaller, it is more demanding to the precision of test.
Utility model content
In order to solve the problems in the existing technology the utility model, provides a kind of test that can test carbon brush elastic force
Device.
In order to achieve the above object, the utility model proposes technical solution be：A kind of carbon brush elasticity test device, including
Rack and probe, the carbon brush are fixed on by torsional spring on workpiece to be tested, and probe is located in rack, which further includes lifting
Cylinder, motor and lifter plate, the lifting cylinder are fixed on the rack, and lifter plate is fixed on the output end of lifting cylinder and can be
Lifting cylinder drives lower up and down motion, motor to be fixed on lifter plate, and output end is equipped with lead screw, probe middle part and lifter plate cunning
Dynamic connection, one end are connect with wire rod thread, and the other end can extend into carbon brush side and be equipped with pressure sensor.
Above-mentioned technical proposal is further designed to：Pressing plate is additionally provided on the lifter plate, the pressing plate passes through straight line
Bearing is slidably connected with lifter plate.
Seat board is additionally provided in the rack, the lifting cylinder is fixed at the top of seat board, and seat board is equipped with the first guide rail, is risen
Drop plate is slidably connected with the first guide rail.
The lifter plate is equipped with the second guide rail, is slidably connected with the second guide rail in the middle part of the probe.
The beneficial effects of the utility model are：
The technical solution of the utility model drives probe to drop to the position of carbon brush side by lifting cylinder, then passes through electricity
Machine drives probe pressing carbon brush, and the elastic force data of carbon brush are obtained by the pressure sensor on carbon brush.
It since the stroke of carbon brush small volume, pressing of popping one's head in is very short, is difficult to control, is driven using motor in the technical program
The mode of lead screw rotation drives probe to move, and stroke effectively controls in turn, ensures the accuracy of elastic force test result.
Pressing plate is additionally provided in the technical program, pressing plate is slidably connected with lifter plate, since the stroke of probe pressing is short, workpiece
Small shaking can all influence test result, so pushing down workpiece using pressing plate in the technical program, prevent workpiece from generating rolling
It is dynamic so that test result is accurate.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is the right view of the utility model.
Fig. 3 is clamp portion enlarged drawing.
In above-mentioned attached drawing：Rack 1, lifting cylinder 2, lifter plate 21, motor 3, lead screw 31, probe 4, pressing plate 5, linear bearing

Specific implementation mode
Below in conjunction with the accompanying drawings and the utility model is described in detail in specific embodiment.
Embodiment
As depicted in figs. 1 and 2, a kind of carbon brush elasticity test device of the present embodiment, including rack 1, probe 4, lifting air
Cylinder 2, motor 3 and lifter plate 21, the carbon brush are fixed on by torsional spring on workpiece to be tested, and the lifting cylinder 2 is fixed on machine
On frame 1, lifter plate 21 is fixed on the output end of lifting cylinder 2 and can move up and down under the drive of lifting cylinder 2, and motor 3 is fixed
On lifter plate 21, and output end is equipped with lead screw 31, and 4 middle part of probe is slidably connected with lifter plate 21, one end and 31 screw thread of lead screw
Connection, the other end can extend into carbon brush side and be equipped with pressure sensor, and when work, lifting cylinder drives lifter plate to decline, directly
It is extend into carbon brush side to probe, then motor 3 rotates, and drives 4 translation of probe, presses carbon brush, and then carry out elastic force test.
As shown in figure 3, being additionally provided with pressing plate 5 in the present embodiment on lifter plate 21, the pressing plate 5 passes through linear bearing 6 and liter
Drop plate 21 is slidably connected, and pressing plate 5 may continue to decline during with lifter plate 21 declining after encountering workpiece, and utilizes itself
Gravity pushes down workpiece.
Seat board 11 is additionally provided in the present embodiment in rack 1, the lifting cylinder 2 is fixed at the top of seat board 11, on seat board 11
Equipped with the first guide rail, lifter plate 21 is slidably connected with the first guide rail.Lifter plate 21 is equipped with the second guide rail, 4 middle part of the probe
It is slidably connected with the second guide rail；It can be control effectively to the movement locus of lifter plate 21 and probe 4 by guide rail.
The utility model is not limited to the various embodiments described above, and all technical solutions obtained using equivalent replacement mode are fallen
In the range of the requires of the utility model is protected.
