Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of forklift post-processing devices, in particular to an air tightness detection fixture for a forklift post-processing component. Background Art
[0002] The forklift aftertreatment device is a device used to treat forklift exhaust gas. It usually includes a bottle body with a catalyst inside to prevent exhaust gas from polluting the air. The flexible filler on the inner wall of the bottle body reduces vibration and ensures the catalytic effect. The filter component of the bottle body intercepts solid particles in the exhaust gas to prevent black smoke in the exhaust gas from polluting the environment.
[0003] There are four main methods for air tightness testing: differential pressure test method, direct pressure method, mass flow method and quantitative test method. The direct pressure method is to directly fill the product with compressed gas of a certain pressure through a pressure regulating valve. After stabilization, the pressure sensor detects the pressure drop or leakage over a period of time. The traditional detection device uses a pressure plug to block the pipe mouth and the cavity flange mouth, and then detects the air tightness of the component. Because the plug goes deep into the pipe mouth and blocks the flange weld, the air tightness detection of the component is not accurate enough, the detection method is single, and there are fewer controllable variables during the detection, which affects the detection effect. Utility Model Content
[0004] The purpose of the utility model is to remedy the defects of the prior art and provide a tooling fixture for testing the air tightness of the post-processing components of a forklift. The utility model pushes and pulls the cylinder to make the rubber pad and the pipe mouth tightly fit, so as to achieve the effect of clamping the post-processing components and sealing the pipe mouth. The air tightness of the post-processing can be tested by an air tightness testing instrument, so that the requirements of the post-processing air tightness testing test can be quickly met, which is convenient and effective, efficient and reduces turnover.
[0005] The utility model is realized by the following technical solutions:
[0006] A tooling fixture for testing air tightness of a forklift post-processing component, comprising a base plate, with tightening devices respectively installed at both ends of the upper side surface of the base plate, the tightening device comprising a cylinder support plate, the cylinder support plate is fixedly installed on the base plate, a cylinder connecting plate is installed on the cylinder support plate, a cylinder is installed on the cylinder connecting plate, a tightening plate is fixed on the moving end of the cylinder, a rubber sealing pad is provided on the surface of the tightening plate, and the cylinder movement directions of the two tightening devices are perpendicular to each other; post-processing component support plates are respectively fixed on the front sides of the two tightening devices on the base plate, and a post-processing component baffle is installed behind one of the post-processing component support plates.
[0007] A post-processing component supporting groove is formed at the upper end of the post-processing component supporting plate.
[0008] The tightening plate is a circular plate.
[0009] The cylinder support plate is fixed on the base plate by bolts.
[0010] An L-shaped notch is provided on the bottom plate.
[0011] The advantages of the utility model are: the utility model installs the cylinder support plate and the post-processing component support plate on the bottom plate, installs the cylinder connection plate on the cylinder support plate, installs the cylinder on the cylinder connection plate, places the post-processing component on the post-processing component support plate, controls the two cylinders to respectively press the pipe opening at the front end and the pipe opening at the side of the rear end of the post-processing component, seals the sealing rubber pad and the pipe opening tightly, uses an airtightness detection instrument to detect, and observes the results.
