Description

Adjustable torque gun with torque adjusting device Technical Field The utility model relates to the technical field of torque gun processing and production, in particular to an adjustable torque gun with a torque adjusting device. Background The torque gun is a tool for applying a preset torque value and is widely applied to the fields of mechanical assembly, automobile maintenance and the like. The torque gun in the prior art usually adjusts the torque threshold value through a spring or a hydraulic mechanism, but has the problems that 1, the torque is unstable, the torque output of a gear transmission system of the traditional torque gun fluctuates due to meshing clearance or abrasion to influence the operation precision, 2, the torque is inconvenient to adjust, the shell is required to be detached or a special tool is used, the operation is complex, and the accurate fine adjustment is difficult to realize. Disclosure of utility model In order to solve the technical problem, a torque gun capable of conveniently and rapidly adjusting torque is provided, and the torque can be accurately adjusted without a disassembling tool by additionally arranging an external torque adjusting device. In order to achieve the aim, the technical scheme adopted by the utility model is that the adjustable torque gun with the torque adjusting device comprises, The gun body is internally provided with a driving motor; A transmission gear set arranged in the gun body and connected with the output shaft of the driving motor, and The torque adjusting device is arranged on the periphery of the gun body, and the position of the torque adjusting device corresponds to the position of the transmission gear set; And the torque adjusting device is rotated to adjust the tooth shape to drive the main gear of the transmission gear set to rotate, so that the torque of the torque gun is changed. According to the utility model, the torque adjusting device is of a sleeve-shaped structure and sleeved on the periphery of the gun body, and the inner wall of the torque adjusting device is provided with an adjusting tooth profile matched with the transmission gear set. According to the utility model, further, the ratio of the number of teeth of the adjusting tooth form to the number of teeth of the main gear of the transmission gear set is 3:1-8:1. Compared with the prior art, the torque adjusting device has the advantages that the torque adjusting operation can be completed by rotating the torque adjuster by bare hands, the adjusting time is shortened to be within 10 seconds from 3 minutes, the gears are meshed for transmission to adjust the torque, the clearance error of the traditional thread adjustment is eliminated, the torque output deviation is less than or equal to +/-2%, the adjusting gear parameters can be adapted to the original gears of torque guns of different types, and the modification cost is low. By additionally arranging an external torque regulator, the adjusting gear matched with the teeth is meshed with the original main gear, so that the torque threshold is directly controlled by the rotary adjusting knob. The utility model solves the technical problems of complicated adjustment and unstable output of the traditional torque gun, and is particularly suitable for a precise assembly scene requiring frequent torque adjustment. Drawings FIG. 1 is a schematic diagram of an adjustable torque gun with a torque adjustment device according to the present utility model; FIG. 2 is a schematic diagram of a torque modulation device of the present utility model; fig. 3 is a schematic view of a gun body structure according to the present utility model.
