Embodiment 1

[0042] combine figure 1 and figure 2 , a kind of filter quality detection equipment that the present invention proposes, comprises frame, is used for detecting the thread quality detection unit of oil hole thread quality, is used for the tightness detection unit of detection tightness, controller 32 and loudspeaker 33.

[0043] The frame includes a workbench 1, an upper bracket 2 and a lower bracket 9, the bearing plate 5 is located above the workbench 1, the bearing plate 5 is driven to move up and down by the cylinder 3 on the upper bracket, and the positioning block 13 is rotatably connected to the bearing plate 5, The positioning block 13 is driven and rotated by the motor 4 on the carrier plate 5; the first through hole 11 for the tap 22 to pass through is opened on the workbench 1; The second through hole communicated with the first through hole 11; the lower bracket 9 is connected with a first lifting plate 19, the first lifting plate 19 is connected with a sleeve 20,...

Embodiment 2

[0058] combine figure 1 , the difference between this embodiment and embodiment 1 is that this embodiment also discloses: combining figure 1 , 4 , the workbench 1 is penetratingly provided with a guide hole, the guide rod 8 is penetrated in the guide hole, and its upper end is connected to the bottom of the bearing plate 5; the second lifting plate 15 is slidably connected to the lower bracket 9, which is located on the first lifting plate 19 On one side of the guide rod 8, and on the movement stroke of the guide rod 8, a spring is connected between the second lifting plate 15 and the lower bracket 9; , the other end is connected on the second lifting plate 15 after passing through the guide wheel 23.

[0059] When the cylinder 3 drives the bearing plate 5 to move downward, the guide rod 8 moves downward thereupon. After the guide rod 8 contacts the second lifting plate 15, the guide rod 8 drives the second lifting plate 15 to move downward. Since the first lifting plate 1...

Embodiment 3

[0063] combine figure 1 The difference between this embodiment and Embodiment 1 is that this embodiment also discloses that: the lower bracket 9 is vertically connected with the first slide rail, and the first lifting plate 19 is fitted on the first slide rail. The cooperation between the first lifting plate 19 and the first slide rail enables the first lifting plate 19 to move on a predetermined path, so as to avoid the phenomenon that the detection process cannot be performed normally due to the displacement of the first lifting plate 19 .

[0064] The lower bracket 9 in the present embodiment is also connected with a lifting plate support 18, the lifting plate support 18 is fixedly connected with a lower spring support pad 17, and is slidably connected with an upper spring support pad 16, and the second lifting plate 15 is connected to the upper spring. On the supporting pad 16 , the spring 14 is connected between the lower spring supporting pad 17 and the upper spring supp...

Abstract

The invention provides a device and a method for detecting the quality of a filter. A positioning block is connected to the lower part of a rotating shaft. The rotating shaft can be driven by a firstdriving mechanism to move up and down, and can be driven to rotate by a second driving mechanism. A tap is located below a first through hole, can be moved by the first driving mechanism, and enters the oil outlet hole of the filter after passing through the first through hole and a second through hole in sequence. A sliding block can move up and down synchronously along with the tap, and a pressure sensor is arranged right above the sliding block. The sliding block abuts against the pressure sensor when the tap completely enters the oil outlet hole of the filter; a gas hood is sleeved on theperiphery of the rotating shaft, and the air pressure sensor is connected to the inside of the gas hood; an air pump communicates with the first through hole through a gas supply pipe, and an air outlet of the air supply pipe is located above an electrically controllable valve; the gas hood abuts against a rotary table when a pressing block abuts against the filter on the rotary table. The devicecan perform the detection of the thread quality and the detection of the sealing performance on the filter, is low in the detection cost of the filter, and is accurate and reliable in the detection result.

Description

technical field [0001] The invention relates to the field of filters, in particular to filter quality testing equipment and a testing method. Background technique [0002] The filter is an accessory of the engine, which can filter impurities or gases. After the filter is processed, in order to ensure the filtering effect of the filter, it is necessary to test the sealing performance of the filter and the thread quality at the oil outlet. At present, the sealing performance test and thread quality test of the filter are carried out separately. The process requires a certain amount of transfer time, and the filter needs to be manually fixed during the test process, and the entire test process requires uninterrupted staff. The operation and detection process are time-consuming and laborious, and the accuracy of the detection results is relatively poor. Contents of the invention [0003] The present invention aims at the deficiencies in the prior art, and provides a filter q...
