Problems solved by technology

[0002] In the current automatic screw locking technology, the bit is usually directly fixed on the spindle position as the screw locking mechanism, and the servo driver is used to control the motor to drive the bit to drive the screw. However, due to the fast speed of the motor and the large inertia of the rotor, when screwing , There will be problems such as the screw being interrupted, the plum blossom groove on the nut slipping, the screw hole slipping, the screw torque being too large, etc., and the failure rate is high.

Embodiment Construction

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0018] The application first proposes a locking screw device, such as figure 1 As shown, the screw locking device 10 of the present embodiment includes a numerical control device 110, a motor 120 and a bit 130, wherein the motor 120 outputs torque under the control of the numerical control device 110, and the motor 120 controls the rotation of the bit 130 with the torque to turn the bit 130 The screw 20 located at the end of the bit 130 is screwed into the screw hole.

Abstract

The application discloses a screw locking method and a screw locking device. The screw locking method includes: when the bit is in contact with the screw, controlling the motor to output the first torque to control the bit to rotate in the first direction to pre-tighten the screw; judging whether the first rotational speed of the bit is less than or equal to the first The preset speed, the first speed is the speed of the bit when the screw is pre-tightened; if the first speed of the bit is less than or equal to the first preset speed, the motor is controlled to output the second torque to control the bit to move along the first direction to make the screw locked, wherein, the first torque is smaller than the second torque. In this way, the problem of uncontrollable final locking torque caused by excessive inertia can be improved, so problems such as broken screws, sliding teeth of the plum blossom groove on the nut, and sliding wires in screw holes can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of mechanical automation, in particular to a screw locking method and a screw locking device. Background technique [0002] In the current automatic screw locking technology, the bit is usually directly fixed on the spindle position as the screw locking mechanism, and the servo driver is used to control the motor to drive the bit to drive the screw. However, due to the fast speed of the motor and the large inertia of the rotor, when screwing , There will be problems such as the screw being interrupted, the plum blossom groove on the nut slipping, the screw hole slipping, the screw torque being too large, etc., and the failure rate is high. Contents of the invention [0003] The present application proposes a screw locking method and a screw locking device to solve the above problems. [0004] In order to solve the above technical problems, a technical solution adopted by the present application ...
