Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of aerospace products, and concretely relates to a small-size filter screen inspection tool. BACKGROUND

[0002] As the first pass of the valve inlet, the filter screen has the function of preventing excess material from entering and plays a crucial role in the valve. The filter screen must be inspected under a microscope with a magnification of more than 30 times. The inspection of small-size filter screens with a diameter of less than Φ10 is difficult: the filter screen is small and is easily damaged when it is clamped and inspected with tweezers; the filter screen has wrinkles that are difficult to observe and are easily missed; and the use of tweezers requires multiple clamping and adjustment of the microscope focus to avoid unobserved parts, resulting in low inspection efficiency.

[0003] Patent document CN212311783U discloses a clamp for clamping a filter screen, which includes a first clamping plate, a second clamping plate, a first pressing plate, and a second pressing plate. The inner side wall of the first clamping plate is fixedly connected with a first connecting rod and a second connecting rod. The first connecting rod and the second connecting rod pass through a third perforation and a fourth perforation, respectively. The outer parts of the first connecting rod and the second connecting rod are respectively sleeved with springs. The inner side wall of the second clamping plate is fixedly connected with a third connecting rod and a fourth connecting rod. The third connecting rod and the fourth connecting rod pass through a first perforation and a second perforation, respectively. The outer parts of the third connecting rod and the fourth connecting rod are respectively sleeved with springs. The first connecting rod and the second connecting rod extend into the second pressing plate, respectively. The third connecting rod and the fourth connecting rod extend into the first pressing plate, respectively. A guide hole is arranged in the middle of the first clamping plate, and a guide block is fixedly connected to the inner side wall of the second clamping plate.

[0004] Although the clamp of patent document CN212311783U facilitates filter screen detection, it still uses the clamping form to fix the filter screen, which can damage the filter screen and block the view, and multiple filter screens cannot be detected at the same time.

[0005] In order to achieve non-damage, non-blind area, and rapid inspection of multiple filter screens at the same time, the utility model discloses a filter screen inspection tool to solve the above problems. UTILITY MODEL CONTENTS

[0021] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0022] like Figure 1 , Figure 2 As shown, a filter inspection fixture includes an upper cover plate 1, a lower cover plate 2, a silicone separator plate 5, a magnet 6, a suction base 7, a hinge 8, and a spur bolt 9.

[0023] The upper cover 1 includes a tempered glass panel 12 and an upper cover frame 11; The tempered glass panel 12 of the top cover is embedded in the frame 11 of the top cover.

[0024] The lower cover 2 includes a lower cover tempered glass panel 22 and a lower cover frame 21; The tempered glass panel 22 of the lower cover is embedded in the lower cover frame 21.

[0025] Hinge 8 connects the upper cover frame 11 and the lower cover frame 21 together.

[0026] The end wall of the silicone isolation plate 5 is accommodated and positioned between the upper cover frame 11 and the lower cover frame 21, and the side wall of the silicone isolation plate 5 is clamped and positioned by the upper cover tempered glass panel 12 and the lower cover tempered glass panel 22. The silicone isolation plate 5 is interwoven horizontally and vertically along the plane of the tempered glass panel 22 of the lower cover plate to form a grid. The grid-shaped silicone isolation plate 5 can separate the abnormal filter screen from the qualified filter screen during the inspection process, prevent them from being misplaced during the inspection process, and record the number of the abnormal filter screen. The suction base 7 can be embedded in the outside of the upper cover frame 11 or the lower cover frame 21. The suction base is made of non-magnetic material. Magnets 6 are evenly arranged in the circular groove opened on one side of the suction base 7, and the magnets are set in relation to the grid of the silicone isolation plate 5. The magnets can magnetically attract the filter screen to the upper cover tempered glass panel 12 or the lower cover tempered glass panel 22. Magnet 6 can be a strong magnet made of one of the following: neodymium iron boron magnet, samarium cobalt magnet, alnico magnet, or ferrite magnet; The jack bolt 9 is used to screw the upper cover plate frame 11 and the lower cover plate frame 21 together; The bolt end of the screw bolt 9 is hinged to the lower cover frame 21. The nut end of the screw bolt 9 abuts against the end face of the upper cover frame 11 on the side opposite to the lower cover frame 21. The nut end of the screw bolt 9 is screwed to the bolt end and drives the upper cover frame 11 and the lower cover frame 21 to move closer to each other, flattening the filter screen. When the nut end of the screw bolt 9 separates from the bolt end, the upper cover frame 11 and the lower cover frame 21 can be opened.

[0027] The working principle of this application is as follows: After the suction base 7 is embedded into the outside of the lower cover plate 2, the small-sized filter screen is transferred to the tempered glass panel 22 of the lower cover plate. By slightly shaking the upper cover plate 1 and the lower cover plate 2, the small-sized filter screen is magnetically attracted to the tempered glass panel 22 of the lower cover plate. The filter screen is placed inside the tempered glass panel 22 of the lower cover plate and is separated into multiple areas by the silicone isolation plate 5. After closing the upper cover plate 1 and the lower cover plate 2, tighten the horn bolts 9 to fix multiple filter screens at the same time.

[0028] This apparatus is used to inspect small-sized filters under a microscope, and any abnormal small-sized filters are recorded. The filters are all on the same plane, and multiple filters can be inspected at once by adjusting the focus only once when using the microscope. The suction base 7 is placed on the outside of the upper cover plate 1, and the entire fixture is flipped over. By slightly shaking the upper cover plate 1 and the lower cover plate 2, the small-sized filters are magnetically attracted to the tempered glass panel 12 of the upper cover plate, allowing inspection of the other side of the small-sized filters.

[0029] The upper cover tempered glass panel 12 and the lower cover tempered glass panel 22 of this fixture are consumable parts. If they are worn, they can be replaced without scrapping the entire fixture.

[0030] This invention uses a tempered glass panel pressing and fixing method, eliminating the need for tweezers and avoiding damage to the filter screen caused by tweezers during clamping. This fixture also eliminates blind spots when inspecting small-sized filters by hand or with tweezers. The fixture's suction base can quickly position and fix the filter screen, and combined with the silicone separator, it can divide the tempered glass panel into multiple small areas, enabling simultaneous inspection of the front and back of multiple filters and distinguishing abnormal filters, thus achieving rapid filter inspection.
