Abstract

The invention provides a tightening torque applying device. A disc-shaped support of the device is provided with a planetary gear mechanism composed of a sun gear and four planet gears, so the sun gear and the planet gears conduct fixed-axis rotation along with shafts on a support formed by the disc-shaped support and an end cover. Internal hexagonal ports are designed at the two ends of the sun gear shaft and the two ends of each planet gear shaft. One end of the sun gear shaft is connected with a torque wrench or a common wrench, one end of each planet gear shaft is connected with an adapter, the wrench is rotated to apply tightening torque, accordingly the torque can be synchronously and uniformly applied to a screw to be tightened through the device, and accelerated assembling of the screw is achieved through the 1:2 transmission ratio of the sun gear to the planet gears.

Description

technical field [0001] The invention belongs to the field of loading tool design, and in particular relates to a device for applying tightening torque, which can synchronously apply tightening torque to four screws uniformly distributed on the circumference. Background technique [0002] For flange structures, a certain number of screws evenly distributed connection method is widely used. The usual assembly method of this type of structure is to tighten them sequentially or symmetrically one by one with tools such as torque wrenches. For the spigot type flange structure with a relatively precise fit, or the need to compress the metal sealing ring between the two parts of the flange, etc., the loading method of tightening the screws one by one will damage the spigot structure or the metal sealing ring. , The force in the circumferential direction of the metal sealing ring is uneven, and the screw assembly and loading speed are slow. Contents of the invention [0003] In o...
