Do you know the difference between ratchet wrench and torque wrench?
Release time:
Dec 05,2022
Ratchet wrench is a tool for manually tightening screws, single-head, double-head multi-specification ratchet ring wrench (fixing hole). It is composed of the main plum blossom sleeve of different specifications and sizes and the slave plum blossom sleeve through the engagement of the female key and the male key of the hinge key. Since the plum blossom sleeve has two specifications of plum blossom-shaped through holes, it can be used to tighten two specifications of screws, which expands the scope of use and saves raw materials and working hours. The movable trigger can easily adjust the angle of use of the wrench. The wrench is used for tightening and tightening screws, and has the characteristics of strong applicability, convenient use and low cost.
A ratchet wrench used to rotate a bolt or nut placed in a narrow or inaccessible position, which is rotatably connected to the end of the operating rod. The method includes: a weight connected to the operating lever, the weight is slidable along the length direction of the operating lever, a front bearing part for blocking the impact of the weight is provided on the operating lever in front of the weight, or a rear weight bearing part for blocking the impact of the weight is provided on the operating lever at the rear of the weight. In addition, the operating lever may also have a front bearing part and a rear bearing part.
ratchet wrench and torque wrench what is the difference.
1. ratchet wrench is composed of main plum blossom sleeves and slave plum blossom sleeves of different specifications and sizes, which are connected by the engagement of the female key and the male key of the hinge key. Because the plum blossom set has two specifications of plum blossom shaped through hole. The movable trigger can easily adjust the angle of use of the wrench. The wrench is used for tightening and tightening screws, and has the characteristics of strong applicability, convenient use and low cost. Torque wrench-also known as torque wrench or torque wrench, torque is the product of force and distance. When tightening screws, bolts, nuts and other threaded fasteners, it is necessary to control the applied torque to ensure that the threads are tightened and not damaged by excessive torque, so it is used for operation. First, set the upper limit of the required torque value. When the torque reaches the set value, the wrench will make a "click" sound or the wrench joint will bend an angle, indicating that it has been tightened and no force is applied. The difference between the two is that the torque of the torque wrench can be set.
The principle of the clicking sound of the 2. torque wrench is very simple, which can be understood in the following steps:
1. After the torque wrench makes a "click" sound, it means that the torque value you require has been reached;
2. The "snap" issued by the torque wrench is generated by its internal torque release structure, the torque release structure is divided into three structures: compression spring, torque release joint and torque push rod.
makes a carta sound principle: First, set the required torque value on the torque wrench (the spring is sleeved on the ejector rod to apply pressure to the torque release joint), lock the torque wrench, and start to tighten the bolt. When the torque value is reached (when the applied torque is greater than the pressure of the spring), there will be an instantaneous disconnection effect. At the moment of the disconnection effect, tap the joint, the metal shell of the wrench makes a "click" sound to confirm the reminder function of reaching the torque value (in fact, it is just like the principle that our arm joint is bent 15 degrees into the iron pipe for an instant and then touches the steel pipe).
