Problems solved by technology

Since the height of the opening is fixed and the structure is inflexible, there are many inconveniences during use, and it is inconvenient for workers to operate on one side of the side plate, and it is inconvenient to directly operate back and forth on both sides. When operating on one side, use tweezers to push It is easy to cause the front end of the material to tilt during the process of the end of the material, which may cause the material that originally met the height requirement to fail the height screening checker due to the tilted front end, resulting in screening errors

Embodiment Construction

[0015] The technical scheme of the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0016] like figure 1 As shown, the traditional height screening inspection tool is to set a side plate 2 vertically on the base 1, and there is an opening 3 at the bottom of the side plate 2. Workers use tools such as tweezers to operate the material, and through this opening 3, the The height is required, otherwise the height exceeds the requirement. Since the height of the opening 3 is fixed, the structure is not flexible, and the workers operate on one side of the side plate 2, it is easy to cause the front end of the material to be lifted when using tweezers to push the end of the material, which may cause the original height requirement to be...

Abstract

The invention discloses a height screening fixture which comprises a base and is characterized by comprising two upper baffles, wherein screw holes are formed in the two upper baffles; screw caps penetrating through the base are arranged in the base; screws penetrate through the screw holes and are inserted into the screw caps of the base; silicone gaskets are fixed on the screws between the upper baffles and the base; a gap smaller than the diameter of a to-be-tested material is arranged between the two upper baffles; bottoms of the both upper baffles are parallel to the base; and a channel used for screening the material is formed between bottoms of the two upper baffles and the base. The structure is flexible, the screening height can be adjusted, and errors caused in an operation process are decreased further.

Description

technical field [0001] The invention relates to a height screening gauge, in particular to a simple and convenient tool for screening products meeting height requirements. Background technique [0002] With the development of miniaturization of electronic products, enterprises have higher and higher requirements for electronic product accessories. The smaller the size, the better when meeting various performance parameters. For example, the smaller the volume of mobile phone accessories and computer accessories, the better. The lower the better. When the height of key spare parts exceeds a certain value, it will affect the assembly of the whole machine, which cannot meet the requirements of miniaturization. Therefore, in industrial production, it is often necessary to carry out height screening for some key spare parts involved in digital electronic products. When the height is lower than a certain value, it is qualified, and when the height is higher than a certain value, ...
