Abstract
The invention relates to a measuring device, in particular to a wave spring pre-pressure testing device. The wave spring pre-pressure testing device comprises an outer frame body, a wave spring clamping device is arranged inside the outer frame body, an inner ejector plate of the clamping device is connected with an ejector plate of the outer frame body through a spring balance, preset force is exerted on the spring balance so as to pull the clamping device to conduct clamping, the height of a wave spring is measured, and the corresponding relation between the height of the wave spring and the preset force is drawn, so that whether the wave spring is qualified or not is detected. The wave spring pre-pressure testing device is simple and compact in structure, low in manufacturing cost and convenient to operate, the curve between the height of the wave spring and pre-pressure can be measured conveniently, and through comparison of the measured curve relation and the standard pre-pressure curve, whether the wave spring is qualified or not can be detected.
Description
Technical field
The present invention relates to a kind of measurement mechanism, specifically refer to a kind of wavy spring pre-pressure testing device.
Background technology
In the bearing chamber of small size asynchronous motor, configuring a slice has the wavy spring sheet of precompression, not only can reduce the axial float of motor, also can reduce vibration and the noise of motor simultaneously.Within the scope of the maximum displacement that wavy spring sheet must make outer race in spring force, its precompression must increase to bearing is being subject under the loaded impact of outside institute all in the state that dynamically coincide.The precompression of wavy spring sheet is selected by the static loads coefficient of bearing, be located at that different stressed lower can to make the power of the easy displacement of outer race be minimum precompression, wavy spring sheet under high pressure there will be wearing and tearing and other complicated applied force situation, and qualified wavy spring sheet precompression should occupy in the precompression curve ranges of regulation.While therefore producing, tackling wavy spring precompression tests to select qualified wavy spring to guarantee the quality of product.
Summary of the invention
The object of this invention is to provide a kind of wavy spring pre-pressure testing device, to reach the object that can select qualified wavy spring while producing.
For realizing above-mentioned technical purpose, the technical solution used in the present invention is: wavy spring pre-pressure testing device, comprise an outer support body, outer support body is provided with top board, base plate, top board is connected by support column with four jiaos of base plates, in base plate bottom, be provided with the supporting seat of hollow, it is characterized in that: support body inside is provided with wavy spring clamping device outside, described wavy spring clamping device comprises inside ceiling panel, bottom platen, between four jiaos of inside ceiling panel and bottom platen, by guide pillar, be connected, under placing in bottom platen carcass and on carcass, upper carcass is provided with backing plate, wavy spring is clamped between carcass and lower carcass, between bottom platen and outer support body base plate, be bolted, by adjust bolt can make bottom platen near or away from outer support body base plate, backing plate both sides, upper carcass top are respectively equipped with backing plate and adjust bolt, backing plate is adjusted bolt through backing plate, bottom platen is connected with outer support body base plate, by adjust backing plate adjust bolt can make backing plate near or away from upper carcass, between inside ceiling panel and outer support body top board, by spring balance, be connected.
This wavy spring pre-pressure testing device is simple in structure, compact, manufacturing cost is lower, easy to operate, can measure easily the curve between wavy spring height and precompression, pass through surveyed curved line relation and standard precompression curve whether relatively can detect wavy spring qualified.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the present invention will be further described.
As shown in Figure 1, wavy spring pre-pressure testing device, comprises an outer support body, and outer support body is provided with top board 1, base plate 2, and top board is connected by support column 3 with four jiaos of base plates, is provided with the supporting seat 4 of hollow in base plate bottom.
As shown in Figure 1, support body inside is provided with wavy spring clamping device outside, this wavy spring clamping device comprises inside ceiling panel 5, bottom platen 6, between four jiaos of inside ceiling panel 5 and bottom platen 6, by guide pillar 7, be connected, under placing in bottom platen 6 carcass 8 and on carcass 9, upper carcass 9 is provided with backing plate 10, wavy spring is clamped between carcass and lower carcass, between bottom platen 6 and outer support body base plate 2, by bolt 11, be connected, by adjust bolt 11 can make bottom platen 6 near or away from outer support body base plate 2, backing plate 10 both sides, upper carcass top are respectively equipped with backing plate and adjust bolt 13, backing plate is adjusted bolt 13 through backing plate 10, bottom platen 6 is connected with outer support body base plate 2, by adjust backing plate adjust bolt can make backing plate near or away from upper carcass, between inside ceiling panel 5 and outer support body top board 1, by spring balance 14, be connected.
The concrete using method of this wavy spring pre-pressure testing device is as follows:
1, wavy spring is placed between upper carcass 9 and lower carcass 8.
2, by lower carcass 8, upper carcass 9, backing plate 10 according to being arranged on shown in accompanying drawing 1 between inside ceiling panel 5 and bottom platen 6.
3, with spanner, clockwise rotate and adjust bolt 11, pull bottom platen 6 to move downward, observe spring balance 14, when the maximum elastic force of spring balance pointed test waveform spring standard code, stop operating and adjust bolt 11.
4, with the hands rotate respectively backing plate and adjust bolt 13, make backing plate 10 form and contact with upper carcass 9, backing plate 10 is not to upper carcass 9 mineralization pressures.
5, with spanner, rotate counterclockwise and adjust bolt 11, spring balance preset force pulls bottom platen 6 to move upward, thereby compresses wavy spring.
6, the height after compressing with kind of calliper wavy spring, the corresponding relation between the height after wave recording spring compression and spring balance preset force, draws wavy spring preset force curve, whether thereby compare with typical curve, to measure wavy spring qualified.
Above-mentioned steps 5 and step 6 are described in detail as follows: for example the preset force F of spring balance is 50Kg, now measure the height H of wavy spring, and F and H form corresponding relation; Then rotate counterclockwise and adjust bolt 11, spring balance preset force F is decreased to 40Kg, again measures the height H of wavy spring, and F and H form corresponding relation; Continue to rotate counterclockwise and adjust bolt 11, thereby spring balance preset force F reduces successively and the corresponding relation of measuring successively wavy spring height H and preset force F is drawn wavy spring preset force curve.
