Embodiment Construction

[0025] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0026] like Figure 1 to Figure 11 As shown, the method for reducing the diameter of a self-locking and reducing diameter manipulator described in this embodiment includes a base, and a mechanical arm a arranged on the base, the free end of the mechanical arm is provided with a self-locking Tight reducer wrench socket.

[0027] The variable diameter wrench includes a screwing head 1, an outer sleeve 2 fixedly connected with the screwing head 1, a floating seat 3, a tensioning mandrel 4 and three clamping jaws 5 that are slidably nested at the lower end of the floating seat 3 at intervals. The outer sleeve is provided with a first center hole 21, the floating seat 3 is located in the outer sleeve 2, and its upper end extends into the first center hole 21 an...

Abstract

The invention discloses a diameter changing method of a self-locking diameter-changing mechanical arm. The diameter changing method comprises a base and a mechanical arm arranged on the base, whereina self-locking diameter-changing wrench sleeve is arranged at the free end of the mechanical arm. Compared with the prior art, a contact head drives a first spring to jack a tensioning mandrel, the tensioning mandrel drives three clamping jaws to move towards the center, and then a screw is clamped preliminarily; then an outer sleeve is rotated, so that inclined surface protrusions of the outer sleeve are attached to the inclined surfaces of the clamping jaws, the clamping jaws are extruded to further move towards the center, then the screw is further firmly clamped, self-locking is realized,two-time diameter-changing movement of the clamping jaws is realized, the diameter changing method can be suitable for screwing screws of different specifications, and the structure is more flexible;and in addition, the inclined surface protrusions of the outer sleeve are matched with the inclined surfaces of the clamping jaws, the torsion of the outer sleeve is converted into the clamping forceof the screw, so that the transmission of larger torque is realized, the slipping phenomenon is avoided, and the diameter changing method is small in size, light in weight, full-mechanical in structure, efficient and reliable.

Description

technical field [0001] The invention relates to a method for reducing the diameter of a self-locking and reducing diameter manipulator. Background technique [0002] Existing wrench sockets can often only be used to screw one type of screw. For screws of different specifications, it is necessary to replace wrench sockets of different specifications, which leads to inconvenience in use. Slippage is prone to occur. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings, and to provide a method for reducing the diameter of a self-locking and reducing diameter manipulator. [0004] For achieving the above object, the concrete scheme of the present invention is as follows: [0005] A method for reducing the diameter of a self-locking and reducing diameter manipulator comprises a base and a mechanical arm arranged on the base, wherein a self-locking and diameter-reducing wrench sleeve is provided at the free end o...
