Description

Technical Field

[0001] The utility model belongs to the technical field of pin testing, and particularly relates to a pin measuring device. Background Art

[0002] PIN needle pins are key components of industrial connectors, which directly determine the quality of products. A reasonable design is crucial. The plug-in PIN needle is used for industrial sockets and plugs, and the pin is inserted into an elastic sleeve. The pin is made of brass, which has better mechanical properties than red copper, but it has a higher specific resistance than red copper and silver. PIN needles are highly precision products with high dimensional tolerance requirements. Therefore, after production, it is necessary to measure the dimensions to see if they are within the design tolerances. However, due to the small size and high precision of PIN needles, manual measurement can only be carried out one by one, resulting in low efficiency and high labor costs. Summary of the Invention

[0004] A pin measuring device includes a frame body, a fixing component installed on the frame body for fixing the pin, and a measuring component for measurement;

[0005] The fixing component includes a first clamping portion fixed on the frame body and a second clamping portion located above the first clamping portion, and further includes a first driving component for driving the second clamping portion to move up / down;

[0006] The measuring component includes a measuring seat plate slidable on the frame body and a measuring portion installed on the measuring seat plate, and further includes a second driving component for driving the measuring seat plate to slide up / down. A plurality of slide rails are provided on the frame body, and sliders for sliding on the slide rails are provided on the measuring seat plate. The second driving component can drive the measuring seat plate to slide up / down on the frame body through the sliders.

[0007] Further, the fixing component further includes a plurality of groups of guide columns located between the first clamping portion and the second clamping portion. The first driving component can drive the second clamping portion to slide up / down on the guide columns.

[0008] Further, the measuring portion includes a plurality of measuring needles provided in the measuring seat plate and sensors for detecting the displacement of the measuring needles. The measuring seat plate is provided with accommodation holes for accommodating the measuring needles. The measuring needles slide in the accommodation holes. The height of the head of the measuring needle protruding from the lower plane of the measuring seat plate is denoted as H, and H is 1 to 2 mm.

[0011] Advantages of the present utility model:

[0012] 1. The present utility model uses two clamping portions to clamp the pin needles. Moving the second clamping portion can adjust different heights to adapt to pin needles of different lengths. Different-diameter holes can also be provided on the clamping portions to adapt to more models of pin needles, with a high degree of generality.

[0013] 2. The measuring portion of the present utility model uses a distance sensor to detect the displacement distance of the probe needle to determine the dimensional tolerance of the pin needle. The measurement speed is fast, multiple groups can be measured at one time, the measurement efficiency is high, and the labor cost is reduced. Description of the Drawings
