Description
Technical Field
The utility model belongs to the technical field of sealed check out test set, especially, relate to a test device of reciprocating oil blanket's seal lip frictional force.
Background
At present, in oil seal product tests, the lip friction of a rotary oil seal is widely measured, and a reciprocating oil seal always has no accurate measurement mode. With the improvement of national vehicle emission standards, the control of a host factory on vehicle energy consumption is more and more strict, and the measurement of the friction force of a reciprocating oil seal lip is imperative.
Disclosure of Invention
An object of the utility model is to improve the not enough of prior art and provide a reciprocal oil blanket lip frictional force test device small, modularization, measurement convenience, high efficiency, low cost.
The utility model aims at realizing like this, a reciprocal oil blanket lip frictional force test device, its characteristics are that the device includes frock and lower frock, and the lower surface of going up the frock is equipped with test column, and it is equipped with test groove to correspond the position with test column on the lower frock, and the test inslot top is equipped with the installation station that is used for the installation to treat experimental oil blanket, and the external diameter of treating experimental oil blanket is fixed with installation station interference fit, the work lip cooperation of test column and oil blanket.
Compared with the prior art, the utility model has the following characteristics of showing and positive effect: the utility model adopts the cooperation of the upper and lower tools and a common automatic tension and compression testing machine (hereinafter referred to as testing machine) to simulate the actual motion working condition of the reciprocating oil seal, has the characteristics of small volume and modularization, and is easy to disassemble, assemble and replace; during measurement, only the reciprocating oil seal is arranged in an installation station of the lower tool, the lower tool is fixed with the lower end of the testing machine, the upper tool is fixed with the upper end of the testing machine, the test movement speed is adjusted, the testing machine is used for measurement, as other forces are measured, special skills are not needed, and the measurement is convenient; the measurement operation time is short, the friction measurement of one oil seal can be completed in 1 minute, the measurement can be more efficiently realized, the product quality can be effectively controlled, the quality risk is reduced, and the invisible profit is increased.
Drawings
The present invention will be described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural diagram of the present invention during the test.
In the figure: 1. go up frock, 2, lower frock, 3, oil blanket, 4, test column, 5, test groove, 6, installation station.
Detailed Description
The utility model provides a reciprocal oil blanket lip frictional force test device, refer to fig. 1, including last frock 1 and lower frock 2, the lower surface of going up frock 1 is equipped with test column 4, be equipped with test column 4 corresponding position on the lower frock 2 and test column 4 cooperation test groove 5, the diameter of test groove 5 is greater than the diameter of test column 4, the top is equipped with the installation station 6 that is used for the installation to wait to test oil blanket 3 in the test groove 5, wait 3 external diameters of test oil blanket and 6 interference fit of installation station, 4 cross sectional shapes of test column select according to the customer requirement, cooperate with the work lip of oil blanket 3.
During installation and use, referring to fig. 1 and 2, a complete oil seal 3 to be tested is installed in an installation station 6 of a lower tool 2 to be fixed, the lower tool 2 is fixed with the lower end of a testing machine, an upper tool 1 is fixed with the upper end of the testing machine, the testing machine is used for measurement, the reciprocating motion condition of the oil seal is simulated, reliable data are provided for measurement of the friction force of the lip of the reciprocating oil seal, the friction force of the lip can be conveniently, efficiently and accurately measured, and due to the small size and modularization, the corresponding size tool which is prepared in advance can be replaced at any time.
The utility model is suitable for an oil blanket of all reciprocating motion forms is measured, and the range of application is extensive, generally is applicable to valve oil blanket, shock absorber oil blanket.
