Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
The technical scheme provided by the embodiment of the disclosure relates to a screwdriver and a screw, wherein the screwdriver can be a torque screwdriver, a user can manually input a standard torque when screwing the screw by using the screwdriver, the standard torque defines the maximum torque when screwing the screw by using the screwdriver, when the torque when screwing the screw by the user is greater than or equal to the standard torque, a handle part of the screwdriver idles or slips, and wire slipping or deformation caused by twisting of the screw by a force with a larger torque is avoided. In the related art, the material used for manufacturing the screw is also many, and the maximum torque that can be borne by screws of different materials is different. Before screwing the screw, a user can hardly determine the maximum torque which can be borne by the current screw, so that the standard torque of the screwdriver cannot be accurately set, and the set standard torque is easily too large or too small. If the set standard torque is too large, the screw can slide or deform; if the set standard torque is too small, it is difficult to effectively screw the screw. According to the technical scheme, when a user uses the screwdriver to screw the screw, the screwdriver can automatically set the maximum torque for screwing the screw according to the material of the screw, screw slipping or deformation caused by overlarge torque is avoided, the maintenance time of equipment is shortened, and the service life of the equipment is prolonged.
FIG. 1a is a flow chart illustrating a screw protection method for a screwdriver according to an exemplary embodiment. As shown in fig. 1a, the screw protection method includes the following steps 101 to 102:
in step 101, a protection torque of a screw is obtained according to the material of the screw.
For example, the common materials for manufacturing the screw include carbon steel, stainless steel and brass.
Carbon steels can be classified into low carbon steels, medium carbon steels, and high carbon steels, as well as alloy steels. The harder the carbon steel containing the greater the hardness, the more flexible the screw, and the more flexible the carbon steel can withstand the greater the maximum torque. The carbon content of the low-carbon steel is less than 0.25 percent, the low-carbon steel is generally called A3 steel at home, and is called 1008, 1015, 1018, 1022 at abroad, and the like, and the low-carbon steel is mainly used for manufacturing products without hardness requirements, such as 4.8-grade bolts, 4-grade nuts, small screws and the like. Low carbon steel has high hardness and low flexibility due to its low carbon content, and thus can withstand a limited maximum torque, i.e., a low protective torque. The carbon content of the medium carbon steel is about 0.25%, the hardness of the medium carbon steel is lower than that of the low carbon steel, and the flexibility of the medium carbon steel is higher than that of the low carbon steel, so that the medium carbon steel can bear larger maximum torque, namely the protective torque of the medium carbon steel is larger. The carbon content of the high-carbon steel is more than 0.45%, and the maximum torque which can be borne is also larger due to the lower hardness and higher flexibility, namely the protective torque is also larger. Alloy steel is obtained by adding alloy elements into plain carbon steel to improve the special properties of steel, for example, 35 chromium molybdenum steel can be added into the plain carbon steel to improve the static strength, impact toughness and fatigue limit; 40 chromium molybdenum can be added into plain carbon steel, so that the low-temperature impact toughness of the steel is improved, and the notch sensitivity of the steel is reduced. The aromatic screw mainly uses SCM435 chrome molybdenum alloy steel, which has larger flexibility, so that the maximum torque which can be borne by the aromatic screw is larger than that of other carbon steels, namely the protective torque is larger.
Stainless steels are mainly classified into martensitic steels, ferritic steels, austenitic-ferritic (duplex) stainless steels, precipitation hardening stainless steels, and the like. Stainless steel of each type is more flexible than carbon steel and therefore can withstand a greater maximum torque than carbon steel and also has a greater protective torque than carbon steel.
The commonly used copper product is made of brass or zinc-copper alloy, and H62, H65 and H68 copper are mainly used as standard parts in the market. Copper-based articles are more flexible and therefore can withstand a greater maximum torque, i.e., their protective torque.
In step 102, the protective torque of the screw is set to a standard torque for driving the screw, the standard torque defining a maximum torque for driving the screw.
For example, after the protection torque of the screw is obtained, the protection torque is set to be the standard torque of the screwdriver, the maximum torque of the screwdriver for screwing the screw is limited, and the screw is prevented from slipping or deforming when the acting force torque of the screwdriver on the screw is large.
According to the technical scheme, when a user uses the screwdriver to screw the screw, the screwdriver can automatically set the maximum torque for screwing the screw according to the material of the screw, screw slipping or deformation caused by overlarge torque is avoided, the maintenance time of equipment is shortened, and the service life of the equipment is prolonged.
In one embodiment, as shown in fig. 1b, in step 101, the protective torque of the screw is obtained according to the material of the screw, and the protective torque can be obtained through steps 1011 and 1012:
in step 1011, the material of the screw is obtained.
In step 1012, the protection torque of the screw is obtained according to the corresponding relationship between the pre-stored material and the protection torque.
For example, a screwdriver may obtain the material of a screw in various ways, for example, in order to facilitate a user to select a suitable product, a manufacturer generally places the same type of screw in a packaging bag, a two-dimensional code for identifying the material of the screw is provided on the packaging bag, and the screwdriver may obtain the material of the screw by scanning the two-dimensional code; or, the user can obtain the material of the screw in other modes, input the material information of the screw on the terminal, and the terminal sends the material information to the screwdriver; or the screwdriver can obtain the material of the screw according to the shape of the screw or the spectral analysis result.
For example, during initialization, the corresponding relationship between the material and the protection torque may be pre-stored in the screwdriver, and the corresponding relationship indicates that screws made of different materials correspond to different protection torques. For example, in the correspondence relationship, the protective torque of a screw made of low carbon steel may be 2 newton meters (Nm), the protective torque of a screw made of medium carbon steel may be 3Nm, the protective torque of a screw made of high carbon steel may be 4Nm, the protective torque of a screw made of alloy steel may be 5Nm, the protective torque of a screw made of stainless steel may be 5.5Nm, and the protective torque of a screw made of brass material may be 6 Nm. After the screwdriver obtains the material of the screw, the protection torque of the screw can be obtained according to the corresponding relation.
According to the technical scheme, the screwdriver obtains the protection torque of the screw according to the corresponding relation between the pre-stored material and the protection torque, and convenience and accuracy of obtaining the protection torque of the screw are improved.
In one embodiment, the screw is placed in a packaging bag, and the packaging bag is provided with a two-dimensional code for identifying the material of the screw. As shown in fig. 1c, in step 1011, obtaining the material of the screw can be achieved by steps 1011a and 1011 b:
in step 1011a, the two-dimensional code on the package is scanned.
In step 1011b, the material of the screw is obtained according to the scanning result of the two-dimensional code.
For example, a camera may be disposed on the screwdriver, when the user uses the screwdriver to turn the screw, the camera switch is first pressed, and the screwdriver indicates the camera to turn on after detecting the pressing. The camera scans the two-dimensional code on the wrapping bag, and the screwdriver can acquire the material of screw according to the scanning result of two-dimensional code.
According to the technical scheme, the manufacturer of the screw marks the material of the screw by printing the two-dimensional code on the packaging bag of the screw, and the screwdriver can acquire the material of the screw by scanning the two-dimensional code, so that the convenience of acquiring the material of the screw is improved.
In one embodiment, as shown in fig. 1d, in step 1011, obtaining the material of the screw may be implemented by steps 1011c and 1011 d:
in step 1011c, a spectral analysis of the screw is obtained.
In step 1011d, the material of the screw is obtained according to the result of the spectral analysis of the screw.
For example, since the absorption spectra of different materials are different, the material of the screw may be determined according to the obtained absorption spectra.
For example, the screwdriver can be connected with the spectrum analyzer through bluetooth or a wireless local area network. When a user needs to use the screwdriver to screw the screw, the screwdriver starts the spectrum analyzer according to the instruction of the user, the spectrum analyzer performs spectrum analysis on the screw to obtain the absorption spectrum of the screw, and then the absorption spectrum is sent to the screwdriver. The screwdriver can determine the material of the screw according to the absorption spectrum.
In the technical scheme provided by the embodiment of the disclosure, the spectral analysis results of different materials are different, so that the screwdriver can obtain the material of the screw through the spectral analysis results, and the accuracy of obtaining the material of the screw is improved.
In one embodiment, in step 1011, when the material of the screw is obtained, the screwdriver may receive material information sent by the terminal, where the material information includes the material of the screw.
For example, the screwdriver can be connected with the terminal through bluetooth or a wireless local area network, the terminal is provided with an APP (Application, Application program) for controlling or monitoring the screwdriver, a user can input material information of the screwdriver on the APP after acquiring the material of the screwdriver through visual inspection or data inquiry and other modes, and the terminal can forward the material information to the screwdriver through the APP.
According to the technical scheme, the screwdriver can be connected with a computer, a mobile phone or other portable equipment of a user and receives material information sent by the computer, the mobile phone or other portable equipment, and convenience in obtaining the material of the screw is improved.
In one embodiment, as shown in fig. 1e, in step 1011, obtaining the material of the screw may be implemented by steps 1011f and 1011 g:
in step 1011f, image information of the screw is acquired, the image information including the shape of the screw.
In step 1011g, the material of the screw is obtained according to the pre-stored corresponding relationship between the shape and the material.
For example, the shapes of screws made of different materials may be different, and during initialization, the corresponding relationship between the shapes and the materials may be pre-stored in the screwdriver, which describes the corresponding relationship between screws of different shapes and different materials. For example, carbon steel can be used for manufacturing a cross-recessed common screw due to its high hardness; the stainless steel can be used for manufacturing the set screw with the end head in the shapes of cone, concave, flat head, cylinder and step because of the characteristic of difficult rusting and higher flexibility; the copper material can be used for manufacturing inner hexagonal and inner hexagonal flower-shaped screws due to the extremely high flexibility.
The screwdriver can be provided with a camera, when a user uses the screwdriver to screw the screw, the screwdriver indicates the camera to be opened, the camera obtains image information of the screw, the screwdriver can obtain the shape of the screw from the image information through an image analysis technology, and then the material of the screw is obtained according to the shape and the corresponding relation between the pre-stored shape and the material.
According to the technical scheme, the screwdriver can acquire the shape of the screw through the camera, so that the material of the screw is acquired, and convenience in acquiring the material of the screw is improved.
The implementation is described in detail below by way of several embodiments.
