Problems solved by technology

Other common transmission mechanisms generally have moving parts that are too worn due to sliding friction and have a short lifespan, which will eventually affect the service life and thus affect the precision requirements of the probe and reduce the life of the probe.

Embodiment 1

[0020] A 4D probe usually includes: a casing, a motor, a transmission mechanism, and a transducer core. Usually the casing is arranged outside the other components to play the role of support and protection. One end of the transmission mechanism is connected to the core of the transducer, and the other end is connected to the motor. The motor drives the core of the transducer to swing. In the prior art, due to the limitation of the structure of the transmission mechanism itself, the precision of the probe is limited. Reduced, in some high-precision applications, often can not meet the requirements.

[0021] Such as figure 1 As shown, the present invention provides a 4D probe transmission mechanism 1 to solve the above problems. The 4D probe transmission mechanism includes: a first transmission shaft 11 , an eccentric connector 12 , a second transmission shaft 13 , a sliding sleeve 14 , a third transmission shaft 15 , at least one connector 16 , and at least one fixed shaft 1...

Embodiment 2

[0046] The present invention also provides a 4D probe, which includes: a casing, a motor, a transmission mechanism, and a transducer core. Usually the casing is arranged outside the other components to play the role of support and protection. One end of the transmission mechanism is connected to the core of the transducer, and the other end is connected to the motor, which is driven by the motor to drive the core of the transducer to swing.

[0047] The transmission mechanism is the transmission mechanism described in Embodiment 1, and the high precision requirement of the 4D probe can be achieved by using the probe of the above transmission mechanism. For the transmission mechanism, refer to Embodiment 1 for details, and details are not repeated here.

[0048] It should be noted that the above fixed connection includes detachable fixed connection, bonding, pre-integrated and so on. The detachable fixed connection may include detachable connections realized by various existi...

Abstract

The invention provides a transmission mechanism. A motor is driven by the transmission mechanism to drive a core part of an energy converter to swing. The transmission mechanism comprises a first transmission shaft, an eccentric connecting piece, a second transmission shaft, a sliding sleeve, a third transmission shaft, at least one connecting piece and at least one fixing shaft. A corresponding 4D probe is provided. By means of the transmission mechanism and the 4D probe, synchronous transmission of the motor and the core part of the energy converter is achieved, and therefore the requirement for high precision of the probe is met.

Description

technical field [0001] The invention relates to the technical field of probes, in particular to a transmission mechanism and a 4D probe. Background technique [0002] The existing 4D probe transmission mechanism, such as worm gear transmission, is a transmission mechanism with gaps. Any transmission mechanism with gaps will cause image distortion due to inaccurate transmission. Rope drive can realize gapless transmission, but when the core swings more than 90 degrees, the motor is nonlinearly controlled, which increases the difficulty of motor control and may reduce the accuracy of the probe. For other common transmission mechanisms, the moving parts generally have excessive wear and short life due to sliding friction, which will eventually affect the service life and thus affect the precision requirements of the probe and reduce the life of the probe. Contents of the invention [0003] In order to solve the above problems, a 4D probe is proposed, which solves the proble...
