Description
Technical Field
The utility model belongs to the technical field of sealing washer counter-force measuring equipment, especially, relate to a measuring device of sealing washer reaction.
Background
The automobile sealing ring is one of important parts of automobile products, and mainly has the functions of sealing various assembly parts of an automobile, absorbing the matching tolerance between the assembly parts, sealing media such as oil, water, gas and the like in automobile parts and preventing foreign matters such as external dust from entering. The reaction of the sealing ring to the mating piece is an important parameter for evaluating the sealing state of the sealing ring. The reaction force of the sealing ring to the mating member can only be measured by a press experiment method through an actual machine tool for manufacturing an engine. The tool is complex in design and manufacture and long in experimental period.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to improve the not enough of prior art and provide a measuring accuracy height, simple structure, the sealing washer reaction force's of being convenient for operation survey device.
The utility model aims at realizing like this, a survey device of sealing washer reaction force, including last connecting block and lower connecting block, its characteristics are upper plate and the last connecting block threaded connection who sets up in last connecting block below, and the upper plate lower surface is equipped with an at least guide pillar with upper plate interference fit, and lower connecting block top is fixed with the base, corresponds the guide pillar position on the base and is equipped with the guide pin bushing the same with guide pillar quantity, guide pin bushing and base interference fit, and the guide pillar is the booth clearance fit with the guide pin bushing, is equipped with the I style of calligraphy slot that is used for placing the sealing washer on the base.
Compared with the prior art, the utility model has the following characteristics of showing and positive effect: the utility model discloses upper plate and base are respectively through last, the lower connecting block links to each other with tensile testing machine respectively, remove the end upward movement through tensile testing machine, drive the base motion, the upper plate keeps the immobility, the sealing washer receives the effect of upper plate and base, produce the compression, the sealing washer is installed in the sealing washer slot, horizontal slip can not take place for the sealing washer of whole test, guarantee the accuracy of test, tensile testing machine removes the displacement and the counter-force size of serving pressure and displacement sensor automatic record upper plate, when the base moves the displacement volume that sets up, the test stops, and output test result N this moment, the counter-force of sealing washer to real machine part on the unit length: f = N/L, reaction force of the entire seal ring against the machine part F1= F × L1; the guide post and the guide sleeve are in small clearance fit, so that the lower plate is ensured to vertically move upwards without tilting when moving upwards. The utility model discloses the integrated level is high, simple structure, and the size is little, does not can measure the counter-force curve of sealing washer with the help of real machine part, and the test procedure is reliable and stable, can be under the condition of not acquireing the engine real machine part, simple survey sealing washer is to the reaction size of real machine part.
