Embodiment
[0039] This embodiment provides an automatic screw locking device, such as Figure 1-5 As shown, it includes a motor 2, a transmission assembly, a cutter head assembly 1 and a clutch mechanism 3.
[0040] Such as figure 1 and 2 As shown, one end of the motor 2 is provided with a power output shaft 21, and two main gears 22 that are sheathed on the power output shaft 21 and rotate in conjunction with it. A cutter head assembly 1 is connected.
[0041] Such as Figure 2-5 As shown, the transmission assembly includes a first shaft 4, a first transmission gear 5, a second shaft 6, a second transmission gear 8 and a pinion gear set.
[0042] Such as Figure 6 As shown, the first rotating shaft 4 is sheathed with a first transmission gear 5 provided in conjunction with it, and the first rotating shaft 4 is suitable for driving the cutter head assembly 1 to rotate.
[0043] The second rotating shaft 6 is sleeved with a first auxiliary gear 7 and a second transmission gear 8 me...

The invention provides an automatic screw locking device. The automatic screw locking device comprises a plurality of tool bit assemblies connected with the same motor through a plurality of transmission assemblies; and a clutch mechanism, which is arranged on the transmission assemblies and has a first working state enabling the multiple tool bit assemblies and the transmission assemblies to rotate in a linkage mode and a second working state enabling the tool bit assemblies to be separated from the corresponding transmission assemblies when the tool bit assemblies are in a locked state. In this way, in the process that the same motor drives the multiple tool bit assemblies to lock a screw, if part of the tool bit assemblies firstly complete screw locking and the screw is kept in the locked state, due to the fact that the clutch mechanism enables the part of the tool bit assemblies to be separated from the corresponding transmission assemblies, therefore the motor can not be affectedto drive the rest of the tool bit assemblies to continue to tighten the screw. Compared with the prior art, a plurality of screws can be locked in place at a time, and reliability is improved.
Description
technical field [0001] The invention relates to the technical field of electric tools, in particular to an automatic screw locking device. Background technique [0002] An electric screwdriver is an electric tool for tightening and loosening screws. In actual production, it is often necessary to tighten multiple screws at the same time. Generally, multiple independent electric screwdrivers are required. Since each electric screwdriver includes an independent motor, transmission assembly and cutter head assembly, it not only takes up space Large and expensive to produce. [0003] In order to solve the above problems, Chinese patent document CN210849105U discloses an automatic locking and unloading screw device suitable for high-voltage pipe busbar fittings, such as Figure 9 As shown, it includes a hollow main gear 01, and a plurality of hollow secondary gears 02 arranged around the hollow main gear 01 and meshed with the hollow main gear 01 respectively. The center of the h...
