Description

Technical Field

[0001] The present application relates to the technical field of vacuum cleaner pipeline detection equipment, and in particular to a multifunctional pipeline detection machine. Background Art

[0002] Vacuum cleaners are commonly used appliances today. The handheld pipe part of a vacuum cleaner includes a main connection end connected to the vacuum cleaner working head and a secondary connection end connected to the control handle. During the production process of the vacuum cleaner pipe assembly, the products produced need to undergo multiple tests to ensure their quality.

[0003] As a connecting part, the pipeline needs to be tested for the conductivity of the circuit elements on the pipeline, the air tightness of the pipeline, and the insulation and pressure resistance of the pipeline. When testing the pipeline, a corresponding fixture is required to support the pipeline. However, the main connection ends and the auxiliary connection ends at both ends of the pipeline have different shapes, and it is not easy to quickly limit and fix the pipeline to ensure that the main connection ends and the auxiliary connection ends of the pipeline are in the accurate testing position. At the same time, when the main connection ends and the auxiliary connection ends of the pipeline are tested, the pipeline is likely to move on the fixture, affecting the test results. Utility Model Content

[0004] In order to improve the convenience of a pipeline multifunctional inspection machine during operation, the present application provides a pipeline multifunctional inspection machine.

[0005] This application provides a multifunctional pipeline detection machine, which adopts the following technical solutions:

[0006] A multifunctional pipeline detection machine includes a chassis, on which is mounted a fixture for placing pipelines, on which is mounted a limit assembly for limiting the pipeline, on which is mounted a fixed adjustment assembly for adjusting the position of the pipeline, and on which is mounted an air tightness detection device, an insulation and withstand voltage detection device, and a continuity detection assembly for testing the flow performance of lines on the pipeline.

[0007] By adopting the above technical solution, the pipeline is placed on the fixture, the limit assembly positions the two ends of the pipeline, the fixed adjustment assembly adjusts the position of the pipeline and fixes the pipeline, so that the pipeline is docked at the accurate position to be tested, which is conducive to improving the accuracy of the pipeline detection results. After the pipeline positioning and fixation are completed, the air tightness detection device, the insulation and voltage resistance detection device and the conduction detection assembly are used to quickly test the performance of the pipeline, which is conducive to improving the efficiency of the pipeline multi-function detection machine during use.

[0008] In a specific feasible implementation scheme, the limit assembly includes a first limit platform and a second limit platform, and the first limit platform and the second limit platform are distributed on both sides of the fixture. The first limit platform and the second limit platform are provided with a first arc inner groove for placing the pipe, and the first limit platform and the second limit platform are provided with a second arc inner groove for placing the main connection end and the secondary connection end of the pipe, and there is a limit step at the connection position of the first arc inner groove and the second arc inner groove.

[0009] By adopting the above technical solution, the pipeline is placed on the first arc inner groove of the first limit platform and the second limit platform, the main connection end of the pipeline is placed on the second arc inner groove position of the first limit platform, and the main connection end of the pipeline is pressed against the limit step position on the first limit platform, and then the secondary connection end of the pipeline is placed on the second arc inner groove position of the second limit platform, which facilitates the rapid parking and positioning of the pipeline and improves the preparation speed of pipeline detection.

[0010] The cam is fixedly mounted on the first platform and is provided with a slide groove, and the fixed adjustment assembly includes a movable plate, and the movable plate is slidably mounted on the first platform through the slide groove, and a connecting groove is provided on the first platform, and the connecting groove is communicated with the slide groove, and a push rod is threadedly connected to the first platform, and the push rod extends into the connecting groove, and a guide groove is provided on the first platform, and the first limit platform is slidably connected to the top block through the guide groove, and the push rod is rotatably connected to the top block, and the side of the top block close to the movable plate is set as an arc surface, and a push rod is installed on the movable plate, and the push rod abuts against the top block, and a spring is installed on the first limit platform, and the spring is arranged in the slide groove, and the spring is connected to the movable plate near one end of the movable plate.

[0011] By adopting the above technical solution, after the pipeline is placed on the first limit platform and the second limit platform, the push rod is rotated to control the push rod to move on the first limit platform, and the push rod pushes the top block to slide on the first limit platform. Through the action of the arc surface on the top block, the top block pushes the push rod to move, and the push rod pushes the movable plate to slide on the first limit platform. The movable plate presses against the main connection end of the pipeline to push the pipeline to move, and finally pushes the pipeline to press the pipeline tightly against the first limit platform and the second limit platform to fix the pipeline, thereby enhancing the stability of the pipeline and preventing the pipeline from moving during the detection process, which is beneficial to improving the accuracy of the detection results of the pipeline multi-function detection machine during use.

[0012] In a specific possible implementation manner, one end of the push rod close to the push block is configured as a spherical surface.

[0013] By adopting the above technical solution, the end of the push rod that contacts the top block is set to a spherical surface, so that the contact area between the push rod and the top block is reduced, the friction between the push rod and the top block is reduced, and the push rod is facilitated to slide on the curved surface of the top block.

The output shaft of the second cylinder is connected to a second push plate that blocks the secondary connection end of the pipe.

[0015] By adopting the above technical solution, the first cylinder and the second cylinder push the first push plate and the second push plate to move respectively toward the first positioning platform and the second positioning platform. The first vent cylinder on the first push plate presses against the main connection end of the pipeline, and the second push plate presses against the secondary connection end of the pipeline. Air is ventilated into the pipeline from the first vent cylinder, and the air pressure detector detects whether the air pressure in the pipeline changes, thereby determining whether the air tightness of the pipeline is good.

[0016] In a specific implementation manner, a sensor for detecting the screws at the main connection end of the pipeline is installed on the first push plate.

[0017] By adopting the above technical solution, the screws at the main connection end of the pipeline are sensed by the sensor, which facilitates the rapid inspection of the installation status of the screws at the main connection end of the pipeline.

[0018] In a specific possible implementation scheme, the conduction detection component includes a powered insertion terminal post, which is mounted on the first push plate, and a powered receiving terminal post is mounted on the second push plate.

[0019] By adopting the above technical solution, the powered insertion end column is inserted into the line contact position of the main connection end of the pipeline, and the powered receiving end column is inserted into the line contact position of the secondary connection end of the pipeline. By passing current into the pipeline from one end of the powered insertion end column, and the powered receiving end column on the other side receives the current and detects it, it is convenient to quickly test the flow condition of the line on the pipeline.

[0020] In a specific feasible implementation scheme, the insulation withstand voltage detection device includes a third cylinder, the output shaft of the third cylinder is connected to a lifting plate, the lifting plate is connected to a step-up transformer, the step-up transformer is connected to an insulation withstand voltage tester, and the insulation withstand voltage tester is installed on the chassis.

[0021] By adopting the above technical solution, when the pipeline installation and positioning is completed, the third cylinder controls the movement of the lifting plate to bring the step-up transformer close to the pipeline, and the product is tested for insulation and voltage resistance through the insulation and voltage resistance tester, which facilitates the rapid testing of the insulation performance of the pipeline.

[0022] In a specific possible implementation scheme, a first arc inner groove is formed on the fixture, and the outline size of the first arc inner groove is the same as the outline size of the pipeline.

[0023] By adopting the above technical solution, the first arc inner groove is provided on the jig and has the same outer contour as the pipeline, so that the pipeline can be placed more stably when the jig is used to place the pipeline.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. Place the pipeline on the fixture, use the limit assembly to position both ends of the pipeline, and use the fixed adjustment assembly to adjust the position of the pipeline and fix the pipeline so that the pipeline is docked at the accurate position to be tested, which is conducive to improving the accuracy of the pipeline detection results. After the pipeline is positioned and fixed, the air tightness detection device, insulation and voltage resistance detection device and conduction detection assembly are used to quickly test the performance of the pipeline, which is conducive to improving the efficiency of the pipeline multi-function detection machine during use.

Through the setting of the fixed adjustment component, after placing the pipeline on the first limit platform and the second limit platform, the push rod is rotated to control the push rod to move on the first limit platform, and the push rod pushes the top block to slide on the first limit platform.
