Description

Technical Field

[0001] The utility model relates to the technical field of measurement and calibration platforms, in particular to a dual-axis rotation measurement and calibration platform supporting wireless communication. Background Art

[0002] Chips need to be calibrated after manufacturing. Tilt angle chip assembly places stringent demands on the production process, and performance is limited by the assembly process, making it difficult to fully unleash it. This results in wasted technical costs and manufacturing difficulties. The lack of a calibration process after assembly of the tilt angle chip leads to relatively poor accuracy in actual use. For example, a chip calibration device disclosed in Chinese patent literature (Patent No.: CN202322520506.2) installs the chip in a mounting hole on a calibration plate. After installation, no fixing mechanism is provided to secure the chip, affecting chip calibration. Furthermore, while the calibration plate can accommodate chips of different sizes, it can only secure one chip of each model at a time.

[0003] To this end, we propose a dual-axis rotation measurement and calibration platform that supports wireless communication. Utility Model Content

[0004] The purpose of the present utility model is to provide a dual-axis rotation measurement and calibration platform supporting wireless communication, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a dual-axis rotation measurement and calibration platform supporting wireless communication, comprising a fixed frame and a calibration element, a base is provided on the top of the fixed frame, a mounting platform is provided on the top of the base, a turntable is provided on the top of the mounting platform, a first transmission mechanism is provided on the top of the turntable, a first servo motor is provided at the front end of the first transmission mechanism, a calibration platform is provided on the top of the first transmission mechanism, a second transmission mechanism is provided on the upper right side of the mounting platform, a second servo motor is provided at the bottom of the second transmission mechanism, a positioning rod is provided on the top of the calibration platform, a sleeve is provided on the upper part of the positioning rod, a positioning block is provided on the top of the positioning rod, a ball is provided on the side of the positioning block, a spring is provided at the bottom of the positioning block, a retaining ring is provided at the bottom of the spring, and a pressure plate is provided at the bottom right side of the sleeve.

[0006] Furthermore, a mounting groove cooperating with the balls is provided on the side of the positioning block, and the balls are provided in two layers, upper and lower, and each layer is provided with three groups of balls.

[0007] Furthermore, the bottom end of the positioning rod is fixedly mounted on the calibration platform, and the retaining ring and the spring are both sleeved on the positioning rod.

[0008] Furthermore, the left end of the turntable is connected to the mounting platform via a shaft, and the right end of the turntable is connected to the second transmission mechanism.

[0009] Furthermore, the first transmission mechanism and the second transmission mechanism both adopt worm gear transmission.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the sleeve drives the pressure plate to move upward, the calibration element is placed under the pressure plate, the sleeve is loosened, the spring pushes the retaining ring, the retaining ring drives the sleeve to move downward, and the pressure plate arranged on the right side of the sleeve quickly fixes the calibration element. There are multiple sets of positioning rods and sleeves on the calibration platform. The calibration platform fixes and calibrates multiple calibration elements at the same time. Two layers of upper and lower balls are arranged on the side of the positioning block to stabilize the movement of the sleeve and avoid the problem that during the process of die-casting the calibration element on the pressure plate, the sleeve is slightly tilted due to the compression of the calibration element by one side of the sleeve, and the friction with the positioning block is increased, resulting in difficulty in pulling the sleeve upward.

Multiple groups of positioning rods 12 and sleeves 11 are provided on the calibration platform 9. The calibration platform 9 fixes and calibrates multiple calibration elements 10 at the same time. Balls 15 are provided on the side of the positioning block 13. The balls 15 are provided in two layers, the upper and lower layers. The balls 15 not only move the sleeve 11 to reduce friction, but also make the up and down movement of the sleeve 11 more stable.

[0017] Among them, the side of the positioning block 13 is provided with a mounting groove that cooperates with the ball 15. The ball 15 is provided in two layers, upper and lower, and each layer is provided with three groups of balls 15. The provision of the balls 15 reduces the friction caused by the movement of the sleeve 11, making the sleeve 11 easier to move. At the same time, the provision of the upper and lower layers of balls 15 stabilizes the movement of the sleeve 11 and avoids the problem that during the process of die-casting the calibration element 10 by the pressure plate 17, the sleeve 11 is pressed against the calibration element 10 by one side, causing the sleeve 11 to tilt slightly, thereby increasing the friction with the positioning block 13 and making it difficult to pull the sleeve 11 upward;

[0018] The bottom end of the positioning rod 12 is fixedly mounted on the calibration platform 9. The retaining ring 16 and the spring 14 are both sleeved on the positioning rod 12. After the sleeve 11 is pulled up and the calibration element 10 is installed, the sleeve 11 is released and the spring 14 pushes the sleeve 11 through the retaining ring 16 to fix the calibration element.

[0019] The left end of the turntable 4 is connected to the mounting platform 3 via a shaft, and the right end of the turntable 4 is connected to the second transmission mechanism 7. Both the first transmission mechanism 5 and the second transmission mechanism 7 adopt a worm gear transmission method.

[0020] Working principle: calibrate the calibration element 10, install the calibration element 10 on the calibration platform 9, pull the sleeve 11 upward, the sleeve 11 drives the pressure plate 17 to move upward, place the calibration element 10 under the pressure plate 17, loosen the sleeve 11, and the spring pushes the retaining ring 16, the retaining ring 16 drives the sleeve 11 to move downward, and the pressure plate 17 set on the right side of the sleeve 11 quickly fixes the calibration element 10. The side of the positioning block 13 is provided with a ball 15, and the ball 15 is provided with an upper and lower layer.
