Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a PIN needle alignment detection fixture. Background Art

[0002] The PIN pin is a metal material used in connectors to conduct electricity. It is mostly used in precision processing fields such as electronic communications, mechanical processing, aerospace, etc. By docking the PIN pin with the corresponding hole of the detection fixture, it is possible to observe whether the PIN pin is skewed, and then determine whether the PIN pin is qualified.

[0003] For example, a Chinese patent with publication number CN206300625U discloses an automatic detection device for detecting the PIN needle alignment of a transmission speed sensor injection molded part. The PIN needle is connected to the PIN needle in the positioning fixture through the pushing action of the cylinder slide rail assembly and the through-beam sensor on the detection fixture by cooperating with the positioning fixture, and the detection fixture, as well as the cylinder slide rail assembly and the through-beam sensor on the detection fixture, and the detection on the detection fixture is observed by the through-beam sensor to determine whether the PIN needle alignment is qualified. This detection process requires the cooperation of multiple detection devices, which makes the detection equipment difficult to carry. Utility Model Content

[0008] The inspection sending mechanism is arranged on the side of the workbench close to the detection mechanism, and the inspection sending mechanism includes a pushing component, and the pushing end of the pushing component is arranged corresponding to the positioning component.

[0009] In one embodiment of the present application, the positioning component includes:

[0010] A limit seat, wherein the inner wall of the limit seat is provided with a clamping portion; and

[0011] A positioning fixture is clamped on the clamping portion.

[0012] In one embodiment of the present application, the positioning fixture is provided with a limiting opening, the limiting opening is arranged facing the pushing component, and the limiting opening is used to align with the front detection PIN needle.

[0029] To solve the problems in the background technology, such as Figure 1 to Figure 2 As shown, the utility model proposes a PIN needle alignment detection fixture, including a workbench 1, a detection mechanism 2 and a test delivery mechanism 3. The detection mechanism 2 is arranged on the table top of the workbench 1, the detection mechanism 2 includes a cylinder 21 and a positioning component 22, the positioning component 22 is arranged in contact with the side wall of the workbench 1, the telescopic end of the cylinder 21 is facing the positioning component 22, the positioning component 22 is used for aligning the PIN needle to be tested, the test delivery mechanism 3 is arranged on the side of the workbench 1 close to the detection mechanism 2, the test delivery mechanism includes a pushing component 31, and the pushing end of the pushing component 31 is arranged corresponding to the positioning component 22.

[0030] It can be understood that a groove is provided on the end surface of the workbench 1, and the cylinder 21 can be screwed into the groove of the workbench 1 by means of screws and nuts. The positioning assembly 22 can be configured so that a positioning fixture 222 is fixed in a limiting seat 221, and the limiting seat 221 is fixed in the groove of the workbench 1. The limiting seat 221 can be screwed and fixed by means of screws and nuts. The positioning fixture 222 is arranged on the end surface of the limiting seat 221, and the positioning fixture 222 is arranged corresponding to the pushing assembly 31 in the inspection delivery mechanism 3; the inspection delivery mechanism 3 is arranged as a combination of the pushing assembly 31 and the sliding assembly 32, and the inspection delivery mechanism 3 is arranged by means of the combination of the pushing assembly 31 and the sliding assembly 32. The telescopic end of the driving member 312 in the pushing component 31 pushes the push plate 311 toward the positioning component 22 of the detection mechanism 2, so that the positioning component 22 can be docked with the PIN needle. When the PIN needle is observed to be docked and adapted with the positioning component 22, it can be determined that the PIN needle is properly positioned. When the PIN needle cannot be fully inserted into the positioning component 22, it is determined that the PIN needle is unqualified. This process of detecting the PIN needle is relatively simple, thereby improving the efficiency of the PIN needle detection, and the detection fixture occupies less space and is convenient to carry.

The size of the limiting openings 2221 is the size of the standard model of the PIN needles to be detected. When the PIN needle is inserted into the limiting opening 2221 for detection and the PIN needle and the limiting opening 2221 are adapted, the alignment of the PIN needle can be judged as qualified. When the PIN needle cannot be inserted into the limiting opening 2221, the alignment of the PIN needle is judged as unqualified.
