Abstract
The utility model relates to a testing device and specifically relates to a waveform spring precompression tester. The tester comprises an outer framework body, wherein the outer framework body is internally provided with a waveform spring clamping device, an inner top board of the clamping device and a top board of the outer framework body are connected through a spring scale, the spring scale is provided with a presetting force pull clamping device for clamping and testing height of a waveform spring, a corresponding relation between the height and the presetting force of the waveform spring is figured out, and thereby whether the waveform spring is qualified can be tested. The waveform spring precompression tester has properties of simple and compact structure, relatively low manufacturing cost and convenient operation and can conveniently test a curve between the height and the presetting force of the waveform spring, and the tested curve relation is contrasted with a standard precompression curve to test whether the waveform spring is qualified.
Description
Technical field
The utility model relates to a kind of measurement mechanism, specifically refers 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.Therefore while production, tackling wavy spring precompression tests to select qualified wavy spring to guarantee the quality of product.
Summary of the invention
The purpose of this utility model is to provide a kind of wavy spring pre-pressure testing device, can select the object of qualified wavy spring to reach while producing.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model 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, be provided with the supporting seat of hollow in base plate bottom, 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, be connected by guide pillar, in bottom platen place under 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, be connected by spring balance.
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 utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
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 inside ceiling panel 5 and four jiaos of bottom platen 6, be connected by guide pillar 7, in bottom platen 6 place under 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, be connected by bolt 11, 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, be connected by spring balance 14.
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, clockwise rotate and adjust bolt 11 with spanner, pull bottom platen 6 to move downward, observation spring balance 14, when the maximum elastic force stipulating, stops operating and adjusts bolt 11 until spring balance pointed test waveform spring standard.
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, rotate counterclockwise and adjust bolt 11 with spanner, 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: the preset force F of for example 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.
