Resonant post welding spot height calibration device

Abstract

The invention discloses a resonant post welding spot height calibration device which comprises a base, a sliding seat, a spring sliding seat, an ejector rod, a support and a clamping seat. The base isof a rectangular platy structure and is arranged on a machine stand of a bench drilling machine; the sliding seat is arranged on the base; two guide rails are arranged on the sliding seat at an interval in parallel along the horizontal direction; a sliding chute extending along the horizontal direction is formed between the two guide rails; the spring sliding seat is embedded into the sliding chute; the ejector rod is inserted onto the spring sliding seat along the horizontal direction; the bottom parts of the support and the clamping seat are connected into a whole and are embedded into thesliding chute; the upper parts of the support and the clamping seat are arranged at an interval along the horizontal direction, and form a clamping groove; a V-shaped groove is formed in the upper part of the support; a resonant post to be height-calibrated is placed in the V-shaped groove along the horizontal direction; and a cap of the resonant post is clamped into the clamping groove along thevertical direction. The resonant post welding spot height calibration device provided by the invention is beneficial to effectively improving the welding spot height positioning accuracy and the appearance of the resonant post, simple in clamping, and high in production efficiency.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a device for calibrating the height of solder joints of resonant columns. Background technique [0002] In RF devices, the frequency bandwidth of each product is different, and the delay value of the corresponding tap is also different. Usually, the delay value is changed by adjusting the height of the solder joint of the tap. After adjusting the height of the solder joint, it is necessary to adjust the height of the adjusted solder joint.

[0002] In RF devices, the frequency bandwidth of each product is different, and the delay value of the corresponding tap is also different. Usually, the delay value is changed by adjusting the height of the solder joint of the tap. After adjusting the height of the solder joint, it is necessary to adjust the height of the adjusted solder joint. To calibrate, in practice, a caliper is generally used to draw a horizontal line on the resonant column from the bottom of the resonant column to the required height on the resonant column, and then draw a vertical line down the center of the edge of the resonant column, and take two crosses The intersection point is the height of the solder joints; if this method is used to calibrate the height of the solder joints, in the actual operation process, each resonant column needs to measure the marking line by manually operating the vernier caliper, and the production efficiency is extremely low; and the vernier caliper is used to mark the line. During the line process, there will be bad phenomena such as blurring the line due to too light force, drawing a long line when the force is too heavy, or sliding the vernier caliper, and the drawn line is inaccurate, etc., which not only affects the appearance of the resonant column, It also affects the performance of the resonant column in radio frequency devices; in addition, when encountering a resonant column with a reel, the caliper will push against the resonant plate, resulting in the inability to scribe or inaccurate scribe
