Description

Device with adjustable stress stroke of radio frequency test probe

Technical Field

The utility model relates to a testing device, in particular to a device for adjusting the stress stroke of a radio frequency testing probe.

Background

Nowadays, with the higher and higher requirements of the market on radio frequency electronic products, the radio frequency test probe is also widely used in the test fields of communication, broadcasting and the like, and is also widely used in the radio frequency signal conduction test of intelligent remote control products such as 2G, 5G, WIFI and the like.

The existing radio frequency test probe is installed in a mode of fixing the relative position, and whether the radio frequency test probe is effectively contacted with a radio frequency antenna pedestal after being pressed down cannot be confirmed, so that the manufacturing requirement of the precision of the clamp is increased, and once the manufacturing error is large, the test clamp needs to be manufactured again or modified. Not only is the manufacturing cost of the clamp increased, but also the project progress is influenced; since the jig is inevitably worn during use, if the wear is excessive, the distance of the RF probe contacting the antenna base is changed, thereby reducing the stability of the test. The clamp cannot be repaired quickly, and the clamp needs to be manufactured or modified again, so that the production is influenced, and the investment of the clamp cost is increased; the existing clamp adopts a fixed radio frequency test probe, and when a product is placed into the clamp to generate position deviation, the radio frequency test probe cannot accurately contact the antenna pedestal, so that the test cannot be performed, and the test efficiency is influenced.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects of the prior art and provide a device for adjusting the stress stroke of a radio frequency test probe, which solves the problems of contact error and incapability of quick repair caused by clamp abrasion by manually adjusting a micrometer and calibrating the position of a radio frequency antenna.

The purpose of the utility model is realized as follows: a stress stroke adjustable device for a radio frequency test probe comprises an air cylinder base, wherein a linear slide rail is arranged on the air cylinder base, a slide block is arranged on the slide rail, a slide plate is arranged on the slide block, a radio frequency needle mounting seat is arranged on the slide plate, and a T-shaped adjusting block is fixed on one side of the radio frequency needle mounting seat; a concave adjusting plate is arranged on one side of the sliding block, a micrometer is mounted at one end of the adjusting plate, a micrometer screw of the micrometer abuts against the T-shaped adjusting block, and a spring is arranged at the other end of the adjusting plate; and the radio frequency test probe is arranged on the radio frequency needle mounting seat.

When the radio frequency testing device works, the radio frequency testing probe is accurately arranged on the radio frequency needle mounting seat, and the radio frequency testing probe can be accurately fixed on the clamp by adjusting the micrometer.

Compared with the prior art, the technical scheme adopted by the utility model has the beneficial effects that: by adopting the micrometer position accurate adjustable device, the position of the radio frequency antenna can be adjusted and calibrated manually, and the problems of contact error caused by clamp abrasion and incapability of quick repair are avoided. The micrometer utilizes a screw pair transmission principle, changes the rotary motion of the screw into linear motion by means of the matching of a micrometering screw and a nut, reads data from the fixed sleeve and the micro-cylinder, and has the precision of 0.001mm, thereby ensuring that the stress between the probe and a product is kept constant; the radio frequency test probe capable of floating is selected, so that the contact problem caused by product putting deviation can be effectively corrected, the stability of production test is improved, the test efficiency is improved, and the product quality is ensured.

Further, an air cylinder is further arranged on the air cylinder base.

In order to ensure the stability of the radio frequency probe, a radio frequency probe pad is arranged between the radio frequency test probe and the radio frequency probe mounting seat.

In order to effectively correct the contact problem caused by the product placement deviation and ensure that the radio frequency test probe and the antenna pedestal can be accurately aligned in the horizontal direction, the radio frequency test probe adopts a floatable radio frequency test probe.
