Abstract
Description
Technical Field
[0001] The utility model belongs to the field of calibration of mechanical instruments. More specifically, it relates to a device for calibrating the torque setting value of a torque screwdriver in an electric manner. Background Technique
[0002] A torque screwdriver is a tool used to control the magnitude of the applied torque when fastening screw, bolt, nut and other threaded fasteners. The torque screwdriver allows the user to set an upper limit of the required torque value. When the applied torque reaches this set value, the torque screwdriver will make a specific sound and rotate idly and slip to avoid over-tightening. The main function of the torque screwdriver is to accurately control the magnitude of the torque acting on the threaded fastener to ensure that the fastener can be firmly connected and will not be damaged due to excessive torque. This tool is usually used in occasions where precise control of the fastening torque is required.
[0003] The torque value upper limit set by the user of the torque screwdriver needs to be strictly controlled. At present, people usually install a hexagonal bit on the torque screwdriver, and then connect the bit to the torque tester adapter. The torque tester adapter is fixed to the torque tester. By manually rotating the torque screwdriver slowly, the torque is increased as evenly as possible until the torque screwdriver makes a specific sound and rotates idly and slips. At this time, the torque tester will read out the maximum torque in this process, and this maximum torque is the upper limit of the torque value set by the user. This test process cannot ensure that the torque increases evenly, and there is an inclination during the rotation process, resulting in an error in the actually measured torque value, and the accuracy cannot be guaranteed.
[0004] The present invention can effectively solve the above problems. The electric rotation platform can adjust the rotation speed to increase the torque evenly. The three-jaw chuck can fix and clamp the torque screwdriver so that it will not tilt, and the clamping force is large enough to ensure that the torque screwdriver will not loosen during the test process. The Z-axis lifting platform can adapt to torque screwdrivers of different lengths and facilitate keeping the centers of the torque screwdriver and the torque tester adapter on the same axis, improving the accuracy of the measurement result. Summary of the Invention
