Description

Technical Field

[0001] The utility model relates to the technical field of airtight detection equipment, in particular to an external fine filter airtight detection tool. Background Art

[0002] Filters are mainly used in automobiles, air compressors and other equipment to filter air or oil, etc. Since filters are used for air and oil filtration, the filter element is an important functional component of the filter. The filter elements used for filters include built-in fine filters and external fine filters, so there are usually very high requirements for their air tightness.

[0003] When conducting air tightness test on the external fine filter, the product to be tested needs to be placed on the testing tooling, then the air outlet of the product to be tested is blocked, and air is inflated into the product to be tested through the air inlet so that the interior of the product to be tested can be filled with the required air pressure. At this time, press the test button, and the testing equipment executes the test procedure to complete the test. After the test is completed, the air outlet needs to be opened to release the air pressure and take out the product after the test is completed.

[0004] When the existing testing tool is used to test the filter, the air inlet and the air outlet need to be opened and closed separately, which is troublesome to operate. Utility Model Content

[0005] The utility model aims to provide an external fine filter air tightness detection tool to solve the problem that the existing detection tool needs to open and close the air inlet and outlet ends separately when testing the filter, which is troublesome to operate.

[0006] In order to achieve the above-mentioned purpose, the basic scheme of the utility model is as follows: an external fine filter airtight detection tooling, including a base, an air inlet end mechanism, an air outlet end mechanism and a detection positioning mechanism, and also including a cylinder and a connecting frame, the detection positioning mechanism is installed on the base, the air inlet end mechanism and the air outlet end mechanism are respectively located at the two ends of the detection positioning mechanism, and the air inlet end mechanism and the air outlet end mechanism are both slidably connected to the base, the connecting frame includes a cross frame, an L-shaped bracket and a wedge block, the cross frame is fixedly connected to the output shaft of the cylinder, the L-shaped bracket is fixed at the end of the cross frame, the wedge block is fixed in the middle of the cross frame, the wedge surface of the wedge block is against the air outlet end mechanism, the air outlet end mechanism is provided with an elastic return member, and the L-shaped bracket is fixedly connected to the air inlet end mechanism.

[0007] Furthermore, the base is provided with at least two air inlet end mechanisms, two air outlet end mechanisms and two detection and positioning mechanisms, and the two air inlet end mechanisms, the two air outlet end mechanisms and the two detection and positioning mechanisms are symmetrically installed on both sides of the cylinder, and two L-shaped brackets are provided, and both side surfaces of the wedge block are wedge surfaces, and the two L-shaped brackets are respectively fixed at the two ends of the cross frame, and the two L-shaped brackets are respectively fixedly connected to the two air inlet end mechanisms, and the two wedge surfaces of the wedge block are respectively against the two air outlet end mechanisms, and the two air outlet end mechanisms are provided with elastic return parts.

[0008] Furthermore, there are two cylinders, and there are four air inlet end mechanisms, air outlet end mechanisms and detection and positioning mechanisms. The two cylinders are symmetrically installed on the base, and the four air inlet end mechanisms, air outlet end mechanisms and detection and positioning mechanisms are symmetrically installed on both sides of the two cylinders.

[0009] Furthermore, the elastic return member is a spring.

[0010] The beneficial effects of this scheme are as follows: (1) The cylinder drives the connecting frame to move, thereby driving the air inlet end to slide, thereby realizing the docking of the air inlet end with the detection positioning mechanism, that is, completing the docking with the product to be detected. At the same time, the wedge block in the middle of the connecting frame presses against the air outlet end mechanism, and gradually presses the air outlet end mechanism and the detection positioning mechanism together during the movement of the wedge block, thereby completing the docking of the air outlet end mechanism with the product to be detected, realizing the closure of the product to be detected, and inflating the air inlet end and blocking the air outlet end respectively, so that the interior of the product to be detected can be filled with the required air pressure. At this time, the detection button is pressed, and the detection equipment executes the detection procedure. After the detection is completed, the cylinder drives the connecting frame to return to its original position, and the air inlet end mechanism moves with the connecting frame. The air outlet end mechanism loses the pressure of the wedge block, and returns to its original position and leaves the detection positioning mechanism under the action of the elastic return member, thereby realizing the synchronous action of the air inlet end mechanism and the air outlet end mechanism, which is convenient and fast, and improves the detection efficiency.

[0011] (2) Multiple air inlet mechanisms, air outlet mechanisms and detection and positioning mechanisms are integrated on a base, so that multiple products can be detected at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] The reference numerals in the drawings of the specification include: base 1, air inlet end mechanism 2, air outlet end mechanism 3, detection and positioning mechanism 4, cylinder 5, cross frame 6, L-shaped bracket 7, wedge block 8, spring 9.

[0015] Example

[0016] Basically as attached Figure 1 As shown: an external fine filter airtight detection tooling comprises a base 1, four air inlet end mechanisms 2, four air outlet end mechanisms 3 and four detection positioning mechanisms 4, two cylinders 5 and two connecting frames, the two cylinders 5 are symmetrically mounted on the base 1, the four air inlet end mechanisms 2, the air outlet end mechanisms 3 and the detection positioning mechanisms 4 are symmetrically mounted on both sides of the two cylinders 5, the air inlet end mechanisms 2 and the air outlet end mechanisms 3 are respectively located at both ends of the detection positioning mechanisms 4, and the air inlet end mechanisms 2 and the air outlet end mechanisms 3 are both slidably connected to the base 1, the connecting frame comprises a cross frame 6, two L-shaped brackets 7 and a wedge block 8, the cross frame 6 is fixedly connected to the output shaft of the cylinder 5, the two L-shaped brackets 7 are respectively fixed at both ends of the cross frame 6, and the two L-shaped brackets 7 are respectively fixedly connected to the two air inlet end mechanisms 2 on both sides of the same cylinder 5, the wedge block 8 is fixed to the middle part of the cross frame 6, both side surfaces of the wedge block 8 are wedge surfaces, the two wedge surfaces of the wedge block 8 are respectively against the two air outlet end mechanisms 3, and the two air outlet end mechanisms 3 are connected with springs 9.

[0017] The specific implementation process is as follows: the cylinder 5 drives the connecting frame to move, thereby driving the air inlet end to slide, thereby realizing the docking of the air inlet end with the detection positioning mechanism 4, that is, completing the docking with the product to be detected. At the same time, the wedge block 8 in the middle of the connecting frame presses against the air outlet end mechanism 3, and gradually presses the air outlet end mechanism 3 and the detection positioning mechanism 4 together during the movement of the wedge block 8, that is, completing the docking of the air outlet end mechanism 3 with the product to be detected, realizing the closure of the product to be detected, and inflating the air inlet end and blocking the air outlet end respectively, so that the interior of the product to be detected can be filled with the required air pressure. At this time, press the detection button, and the detection equipment executes the detection procedure. After the detection is completed, the cylinder 5 drives the connecting frame to return, and the air inlet end mechanism 2 moves with the connecting frame, and the air outlet end mechanism 3 loses the pressure of the wedge block 8, and returns to leave the detection positioning mechanism 4 under the action of the spring 9, realizing the synchronous action of the air inlet end mechanism 2 and the air outlet end mechanism 3, which is convenient and fast, and improves the detection efficiency.
