Description

Technical Field

[0001] The utility model belongs to the technical field of measurement, and particularly relates to a quick detection fixture for the dimensions of cylindrical parts. Background Art

[0002] Cylindrical parts are very commonly used parts in mechanical equipment and can be used as shafts or bushings. Therefore, the inner diameter and length dimensions are very important. After production, it is necessary to measure the core dimensions to meet the design tolerance requirements. However, the measurement is often carried out manually. Whether using calipers or measuring equipment, manual detection is required one by one, resulting in very low efficiency and high labor costs. Summary of the Invention

[0003] To solve the above technical problems, a technical solution adopted by the utility model is:

[0004] A quick detection fixture for the dimensions of cylindrical parts, comprising a frame body, a blocking structure and a detection structure mounted on the frame body;

[0005] The frame body includes a go-no-go part for detecting the length of the cylindrical part and a loading part, and the cylindrical parts are arranged in sequence in the loading part;

[0006] The blocking structure includes a rotating shaft and a baffle plate rotatably connected to the loading part through the rotating shaft, and the baffle plate is used to block the falling of the cylindrical part;

[0007] The detection structure includes a sliding seat sliding on the frame body, a detection column and a baffle plate mounted on the frame body. The baffle plate is connected to the frame body through an elastic element, and a blocking post is further provided on the baffle plate. The detection column is used to detect the inner diameter of the cylindrical part, and the baffle plate blocks the outlet of the go-no-go part.

[0008] Further, the loading part is a U-shaped groove, and the parts are arranged vertically from top to bottom in sequence. A baffle plate is provided on any side of the U-shaped groove, and the baffle plate is used to prevent the parts from falling;

[0009] The bottom surface of the go-no-go part is an inclined surface, which is inclined downward by 15-25° from the loading part towards the go-no-go part. The width of the go-no-go part is denoted as W, and W is used to control the length dimension tolerance of the cylindrical part. When the length of the cylindrical part is within the tolerance range, it can roll out towards the outlet along the inclined surface. If it exceeds the tolerance, it cannot roll and is recorded as a defective product.

[0010] Further, the baffle plate is fixedly connected to the sliding seat, and the detection column is fixedly connected to the sliding seat. When the sliding seat is pulled outwards, the detection column and the baffle plate are driven to be pulled outwards, and the cylindrical part is separated from the detection column.

[0011] Furthermore, the slide seat is provided with a receiving hole for the movable baffle post, and the baffle post is fixedly connected to the baffle plate.

[0012] Furthermore, the elastic element is a spring, one end of the spring abuts against the material baffle plate, and the other end of the spring abuts against the frame body, and the elastic element is used to reset the material baffle plate.

[0013] Beneficial effects of the utility model:

[0014] The loading part of the utility model can arrange multiple cylindrical parts in sequence, use a baffle to block them, and after the baffle is pushed open and a part falls off, the baffle is locked, and the part slides down along the inclined surface. If it can slide to the baffle plate, it meets the design tolerance; if it is blocked by the baffle plate, it is a defective product. The slide seat is pushed forward, and the diameter of the detection column matches the inner diameter of the cylindrical part. If it can enter, the tolerance is met, if it cannot enter, it is a defective product, and then the slide seat is retracted. At first, only the slide seat is retracted. When the baffle column completes the stroke of the slide seat accommodating hole, the detection column is separated from the cylindrical part, the spring is compressed, the baffle plate is pulled open, and the part rolls out. After the return stroke, the elastic element first resets the baffle plate, and then the baffle is pushed open to put down the next part. The utility model avoids the use of frequent manual measurement using measuring tools, and can measure the diameter and length at the same time, thereby improving production efficiency and reducing labor costs.
