Embodiment 1

[0032] see Figure 1 to Figure 5 , the smart wrench of this embodiment includes a handle 1, a housing 2, a transmission mechanism and a sleeve 7, the transmission mechanism is arranged in the housing 2 and includes a driving device 3 and a transmission shaft 4 driven by the driving device 3, the transmission The shaft 4 is connected with the sleeve 7. When working, the sleeve 7 matches the bolt and controls the transmission mechanism to start, so as to realize automatic tightening or dismounting.

[0033] Such as image 3 and Figure 4 As shown, the sleeve 7 in this embodiment includes a locking disc 71 and an adjustable locking member 70, the adjustable locking member 70 is arranged on the locking disc 71, and the adjustable locking member 70 includes several locking sliders 73 and the number of connecting pieces 74 equal to the locking sliders 73, the two ends of the connecting piece 74 are respectively connected with the adjacent two groups of locking sliders 73, specific...

Embodiment 2

[0045] The usage method of the smart wrench in the present embodiment adopts the smart wrench in the embodiment 1, comprising the following steps:

[0046] 1) Rotate the adjusting ring 75 according to the size of the bolt to be screwed, so that the size of the opening 730 of the adjustable locking member 70 is adapted to it;

[0047] 2) Adjust the universal transmission device 5 through the control device 10, so that the sleeve 7 reaches the required bending angle;

[0048] 3) set required torque by control device 10;

[0049] 4) Start the device through the control device 10 .

Abstract

The invention provides an intelligent wrench. The intelligent wrench comprises a handle, a shell, a transmission mechanism and a sleeve. The transmission mechanism is arranged inside the shell and comprises a driving device and a transmission shaft, and the transmission shaft is connected with the sleeve. The intelligent wrench is characterized in that the sleeve comprises a locking plate and an adjustable locking part, the adjustable locking part is arranged on the locking plate and comprises a plurality of locking sliding blocks and connecting pieces, and the number of the locking sliding blocks is equal to that of the connecting pieces; the two ends of each connecting piece are connected with the two corresponding adjacent locking sliding blocks; each locking sliding block comprises a first abutting face and a second abutting face, the first abutting face of each locking sliding block abuts against the second abutting face of the corresponding adjacent locking sliding block, and the first abutting faces can slide relative to the second abutting faces; and a wrench jaw with a size-adjustable opening is defined by the first abutting faces of the locking sliding blocks in an enclosed mode, and the locking sliding blocks are matched in sequence so as to make the wrench jaw form a regular polygon structure. The intelligent wrench is simple in structure, reasonable in design, high in working efficiency, wide in application range and capable of being operated in a narrow and small space.

Description

technical field [0001] The invention relates to an intelligent wrench, which is an electric tool. Background technique [0002] Used in automation and industrial applications, it is common to use a wrench to apply force to a workpiece. But for the corner, or the place where there are many front and rear obstacles and the operation is difficult, because the existing wrench is large in size, it is difficult to put it in, and the screws and nuts in different positions and directions can only be screwed in a fixed direction, which cannot be used normally. Simultaneously, in the process of using, because the size and specification of the bolt parts to be screwed are different, it is necessary to frequently replace the corresponding sleeve, which is very inconvenient to use. [0003] There are very few improvements to the use of wrenches in narrow places in the existing market, and most of them have complicated structures and constant adjustments. [0004] Application No. 201320...
