Problems solved by technology

Since the power source and the static measurement sleeve are not in the same axis, the power transmission must be realized through a belt, etc., which increases the measurement error and increases the consumption of energy efficiency. At the same time, the firmness of the entire wrench is also affected.

Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with specific embodiments.

[0019] reference image Figure 1 to Figure 5 , a new type of pneumatic digital display torque wrench, the pneumatic digital display torque wrench is composed of two coaxial torque measurement devices, namely a dynamic torque measurement device and a static torque measurement device.

[0020] The dynamic torque measurement device includes a dynamic torque measurement magnetoelectric generator 5, a dynamic measurement fixed frame 11, a dynamic torque measurement gear 8, and a central axis air motor 12. The central axis air motor 12 is used to drive the central axis 3 to rotate, and the dynamic torque measurement magnetoelectric The generator 5 is fixed on the dynamic measurement fixed frame 11, the dynamic measurement fixed frame 11 is coaxial with the central axis 3, the dynamic torque measurement gear 8 is fixed on one end of the central axis 3, and is sleeved inside the ...

Abstract

The invention discloses a pneumatic digital-display torque wrench, which consists of a dynamic torque measuring device and a static torque measuring device, which are coaxial torque measuring devices. Dynamic torque and static torque can be measured by using one torque wrench, a power source of a static torque measuring sleeve is coaxial with the static torque measuring sleeve, and power can be directly transmitted through a cylinder so that errors and energy consumption caused by power transmission through belts and the like can be avoided. In addition, a casing of the pneumatic digital-display torque wrench can be relatively regularly cast into a whole, and thereby tightness, environmental interference resistance and stability of the pneumatic digital-display torque wrench are improved.

Description

technical field [0001] The invention relates to a pneumatic digital display torque wrench. Background technique [0002] There are many types of pneumatic digital display torque wrenches, which are used in various industries and occasions. Some wrenches can only measure dynamic torque at relatively high speed, but cannot measure torque at rest or at relatively low speed, which brings inconvenience to some applications, so there is a pneumatic data that can measure both dynamic torque and static torque. The display torque wrench makes the torque measurement belt much more convenient. At present, the pneumatic digital display torque wrench that can measure dynamic and static torque at the same time is to add a motor or other power source above or below the original dynamic measurement sleeve to provide power for the static torque measurement sleeve. Since the power source and the static measurement sleeve are not in the same axis, the power transmission is realized through a...
