Abstract

The utility model discloses a kind of compression springs that ratio of height to diameter is bigger than normal to test auxiliary clamp, includes pedestal and guide sleeve, and 1 is respectively provided in pedestal and guide sleeve and is put into hole, being put into hole for pedestal is equipped with guide rod, and the bottom of pedestal is equipped with pedestal positioning convex platform.The utility model has the advantages that the following aspects:1, it fundamentally solves the problems, such as that ratio of height to diameter compression spring test position fix bigger than normal is difficult, the situation that compression spring is bent and bullet is winged no longer occurs;2, the compression spring tester scope of application is extended, the utilization rate of instrument is improved, ratio of height to diameter compression spring bigger than normal can also measure;3, pedestal, sheath, guide rod have versatility and modularization feature, can be measured to select various sizes of fixture according to the compression spring of different ratio of height to diameters;4, the measured material is the reproduction of compression spring actual working state, more can really reflect mechanical state when compression spring uses.

Description

A kind of compression spring that ratio of height to diameter is bigger than normal test auxiliary clamp
Technical field
The utility model is related to a kind of compression springs to test auxiliary clamp, the especially a kind of compression spring that ratio of height to diameter is bigger than normal test auxiliary Fixture.
Background technology
As contactor uses the expansion in field, contactor small product size constantly to increase, the length of compression spring also constantly increases, And developed to larger ratio of height to diameter direction, ratio of height to diameter:B=L/D, wherein L:The drift of compression spring, D are the central diameter of compression spring.Press Spring is more and more elongated, due to can not effectively be positioned to compression spring in compression spring test equipment, is examined to the pressure of compression spring It just will appear compression spring bending, the situation that bullet flies when survey, in compression spring compression process, the mechanical property of compression spring caused to be unable to get effectively Detection needs to detect mechanical index when compression spring is compressed to specific length for contactor, contactor mechanical resilience power and Whether contact reaches that requirement is directly related with spring, and the every mechanics and environmental performance for directly influencing contactor refer to Mark.Therefore, it is badly in need of providing a kind of auxiliary clamp measuring ratio of height to diameter compression spring bigger than normal.
Invention content
The purpose of the utility model is to provide a kind of compression springs that ratio of height to diameter is bigger than normal to test auxiliary clamp.Solve ratio of height to diameter Compression spring pressure detecting bigger than normal can not effective position the problem of.
The technical solution of the utility model:A kind of compression spring that ratio of height to diameter is bigger than normal test auxiliary clamp includes pedestal and is led It covers, 1 is respectively provided in pedestal and guide sleeve and is put into hole, being put into hole for pedestal is equipped with guide rod, and the bottom of pedestal is fixed equipped with pedestal Position boss.
Ratio of height to diameter above-mentioned compression spring bigger than normal tests auxiliary clamp, and the hole inner wall that is put into of the pedestal is equipped with screw thread, is oriented to The bottom connection fixing base of bar, fixed seat outer wall are equipped with screw thread.
Ratio of height to diameter above-mentioned compression spring bigger than normal tests auxiliary clamp, and the guiding rod head end is equipped with clamping part.
The beneficial effects of the utility model:Compared with prior art, the utility model has the advantages that the following aspects:
1, it fundamentally solves the problems, such as that ratio of height to diameter compression spring test position fix bigger than normal is difficult, compression spring bending and bullet no longer occurs Winged situation;
2, the compression spring tester scope of application is extended, the utilization rate of instrument is improved, ratio of height to diameter compression spring bigger than normal can also be surveyed Amount;
3, pedestal, sheath, guide rod have versatility and modularization feature, can be come according to the compression spring of different ratio of height to diameters Various sizes of fixture is selected to measure;
4, the measured material is the reproduction of compression spring actual working state, more can really reflect mechanics shape when compression spring uses State.
Description of the drawings
Attached drawing 1 is the structural schematic diagram of the utility model;
Attached drawing 2 is the structural schematic diagram of guide rod;
Reference numeral:1- guide sleeves, 2- compression springs, 3- guide rods, 4- pedestals, 5- pedestal positioning convex platforms, 6- fixed seats, 7- clampings Portion.
Specific implementation mode
The utility model is further described with reference to the accompanying drawings and examples, but is not intended as to the utility model The foundation of limitation.
The embodiments of the present invention:A kind of compression spring that ratio of height to diameter is bigger than normal test auxiliary clamp, as shown in attached drawing 1-2, packet Pedestal 4 and guide sleeve 1 have been included, 1 is respectively provided in pedestal 4 and guide sleeve 1 and is put into hole, being put into hole for pedestal 4 is equipped with guide rod 3, bottom The bottom of seat 4 is equipped with pedestal positioning convex platform 5.
Using the fixture when carrying out pressure detecting to ratio of height to diameter compression spring 2 bigger than normal, pedestal 4 is placed in instrument working face On, pedestal positioning convex platform 5 and the mounting hole position of instrument center of working face position are coordinated, to ensure that fixture positions, by attached drawing 1 It is shown to measure preceding preparation, two head ends of compression spring 2 are caught in being put into hole of guide sleeve 1 and pedestal 4, while making guide rod 3 It is penetrated from compression spring 2, at this time by the pressure zero setting of measuring instrument, presses normal compression spring pressure detecting program immediately, carry out pressure Detection.Under the limition orientation of pedestal 4, guide rod 3 and guide sleeve 1, it is avoided that the situation that the bending of compression spring 2 and bullet fly completely.
The hole inner wall that is put into of the pedestal 4 is equipped with screw thread, the bottom connection fixing base 6 of guide rod 3, and 6 outer wall of fixed seat is set There is screw thread.The setting can be put into the guide rod 3 of different length, the compression spring 2 for testing different length.
3 head end of the guide rod is equipped with clamping part 7, and clamping clamping part 7 using spanner or other tools can be by it It fixes, be conveniently threaded into or back-out.
