Description
Technical Field
The application relates to the technical field of pipeline air tightness detection, in particular to a multi-station pipeline clamping device and a pipeline air tightness detection device.
Background
In the refrigeration process of the air conditioner, after a gas refrigerant is compressed into a high-temperature high-pressure gas refrigerant by a compressor, the gas refrigerant is conveyed to a condenser (namely, an outdoor unit) for heat dissipation and is changed into a normal-temperature high-pressure liquid refrigerant, and the normal-temperature high-pressure liquid refrigerant is conveyed to a capillary tube, and after the normal-temperature high-pressure liquid refrigerant flows to an evaporator (namely, an indoor unit) from the capillary tube, the pressure is reduced due to sudden increase of space, the liquid refrigerant is gasified to absorb a large amount of heat, and refrigeration is realized.
Accordingly, various types of pipe assemblies are provided in the air conditioner, for example, a flow divider assembly, a liquid collector assembly, a capillary tube assembly, an electronic expansion valve assembly, and a pipe assembly having a diameter of 6mm or less. In order to ensure the air tightness of the air-conditioning duct, before the duct assembly is assembled, air tightness detection needs to be performed on each duct assembly. Under the prior art, often will wait to detect the pipeline subassembly through the manual work and place on anchor clamps, wait that anchor clamps will wait to detect the pipeline subassembly and press from both sides tight back, carry out the shutoff with the export of this pipeline subassembly and carry out the pressurize test to this gas tightness that detects each pipeline subassembly.
The existing detection mode generally adopts a mode of manually installing and disassembling a pipeline assembly, and three operations of feeding, testing and blanking are sequentially executed in one station.
The application document with the patent number of CN205333272U discloses a multi-station quick connector tightness detector, which comprises an index plate driven by a servo driving motor to realize stepping rotation; and a feeding station, a static sealing detection station, a dynamic sealing detection station and a material taking station are sequentially arranged around the dividing plate. The positions on the index plate corresponding to the four stations are provided with the same number of clamping jigs for positioning the quick connectors. Meanwhile, detection manifolds are arranged on the static sealing detection station and the dynamic sealing detection station, and are arranged right above the clamping jig; when the leakproofness is detected, the cylinder drives the detection manifold to move towards the quick coupling that presss from both sides the dress tool and await measuring the butt, seals the quick coupling that awaits measuring through detecting the manifold with press from both sides the dress tool to carry out the pressurize test under sealed environment.
When the graduated disk is rotatory, detection manifold and the clamp dress tool are divided, and detection manifold does not follow the graduated disk rotation, and the clamp dress tool follows the graduated disk rotation. When the dividing plate rotates, the quick connector to be tested is fixed only through the clamping fixture.
However, the capillary tube assembly of the air conditioner is not a standard part, and the shape and the structure of the capillary tube assembly of different models are different. When the capillary component structure that needs to test is comparatively complicated, need redesign a set of shape adaptation press from both sides dress tool, new clamp dress tool manufacturing cycle is longer, leads to the capillary component that awaits measuring to pile up on the detection process.
Therefore, it is highly desirable to design a multi-station blockage detecting device capable of clamping multiple types of capillary components, which can simultaneously perform three steps of feeding, blockage detecting and blanking, and improve the detection efficiency.

Specifically, the number of the male connectors is one.
Illustratively, the male connector and the female connector 101 are rubber interfaces, respectively.
In practical applications, when the clamping assembly 20 rotates the pipe to be tested to the position of the testing assembly, the female connector 101 rotates to the position corresponding to the male connector at the same time. The male connector is driven by the connector driver to move towards the female connector 101 and abut the female connector 101. When the male joint and the female joint 101 are completely abutted, the rubber joints of the two are mutually pressed to realize sealing.
When the air tightness is detected, the blockage detector, the male connector, the female connector 101 and the pipeline to be detected are connected through an air path, and the blockage detector introduces air into the air path to increase air pressure until the air pressure reaches detection air pressure. If the air path reaches the detection air pressure, keeping for 10 to 60 seconds, and if the air pressure of the air path is greater than the detection air pressure, determining that the pipeline to be detected is a qualified pipeline; if the gas path cannot reach the detection pressure or the gas path is lower than the detection pressure within 10 to 60 seconds, the pipeline to be detected is an unqualified pipeline.
Further, the pipeline air tightness detection device also comprises a feeding component and a discharging component; the material loading assembly, the detection assembly and the material unloading assembly are sequentially arranged around the rotary disc 10 in the circumferential direction.
Specifically, the number of the clamping assemblies 20 is 6, and the clamping assemblies are uniformly arranged on the turntable 10; the turntable 10 rotates 60 degrees at a time.
The arrangement of the feeding station, the detection station and the blanking station as shown in fig. 7; further, the feeding assembly is arranged at the feeding station and used for placing the pipeline assembly to be detected on the clamping assembly 20;
in the embodiment of the present application, the feeding assembly clamps the pipeline to be tested and places the pipeline on the clamping assembly 20, the turntable 10 rotates by 60 degrees, and the feeding assembly clamps the pipeline to be tested again and places the pipeline on the next clamping assembly 20.
Furthermore, the blanking assembly is arranged at the blanking station and used for taking out the detected pipeline assembly.
In the present embodiment, as the inspected pipe is rotated to the blanking station, the clamping assembly 20 releases the inspected pipe while the blanking assembly removes the inspected pipe from the clamping assembly 20. The turntable 10 rotates 60 degrees and the blanking assembly again takes the detected pipe out of the next clamping assembly 20.
In this application embodiment, carousel 10 is rotatory 60 degrees at every turn, and material loading subassembly, unloading subassembly and determine module go on unloading and gas tightness detect operation in step respectively, have improved detection efficiency.
With regard to the apparatus in the above-described embodiment, the specific manner in which each module performs the operation has been described in detail in the embodiment related to the method, and will not be elaborated here.
