Description
Technical Field
The disclosure belongs to the technical field of communication, and particularly relates to a torque value setting method and system for a torque wrench and a server.
Background
In industrial production lines, many operations for fastening using screws are required, and these fastening operations cannot exceed a predetermined torque. This requires the use of a torque wrench to ensure that the tightening operation does not exceed a predetermined torque by setting the correct torque value on the torque wrench.
However, torque values typically differ for different locations in the plant. Workers at the same station face the problem of switching between different torque values when performing fastening operations at different locations in the same factory. That is, it may be necessary to frequently switch the same torque wrench between different torque value settings, or to replace different torque wrenches according to the position.
The former method requires a different manual change of the torque value on the torque wrench, which may result in a manual malfunction, such as forgetting to change the setting, or setting a wrong value. The latter method requires continuous replacement of the wrench, and also causes human error, such as replacement of the wrong torque wrench.
Currently, CN111604847A proposes an electric wrench, which can automatically set a torque value. It is mainly based on "the bolt is according to its size and intensity grade", confirm a torque value, and set it on the electric spanner. Since the fastening torque value determined according to "the bolt according to its size and strength level" is generally a range of values, not a fixed value. This means that such a wrench and torque setting method is not applicable in all situations.
Different factories and different fastening positions do not mean that corresponding torque values are necessarily the same even if bolts with the same size and strength grade are used. Because the bolt with the determined size and strength grade achieves the fastening effect, the applicable torque value has a workpiece taking range, namely the fastening effect can be considered to be achieved as long as the finally formed torque value is in the interval; secondly, the fastening torque value required under actual working conditions is often different by using different factories and different fastening positions with the same size and strength grade.
Thus, for the electric wrench in CN 111604847A:
(1) if the torque value corresponding to the bolt with any size and strength grade is set as the minimum value of the standard fastening torque interval, the required fastening requirement may not be met at some positions of some factories. The bolt per se meets the standard requirements, but a larger torque value is needed for a factory to meet the fastening requirements of the factory per se;
(2) if the torque values corresponding to bolts of any size and strength grade are set as the maximum values of the standard fastening torque interval, although all the fastening positions of the factory using bolts of the corresponding size and strength grade can achieve the fastening effect, the bolts may be damaged due to the fact that the bolts cannot bear the torque values of such a large size and strength grade based on the material characteristics of the factory.
Therefore, in the prior art, only for a specific class of bolts, the station for fastening by using the bolts can achieve the bolt-based fastening effect. But does not ensure that the fastening effect achieved meets the requirements of the station itself or that the plant is not damaged. Meanwhile, when the torque value of the torque wrench is set, the influence of human operation errors cannot be avoided.

Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
In order to solve the problem that in the prior art, only specific types of bolts are used, and the bolt-based fastening effect can be achieved by using the bolt fastening station. But it cannot be ensured that the achieved fastening effect meets the requirements of the station itself, or that no damage to the factory is ensured, and that the influence of human operation errors cannot be avoided when setting the torque value of the torque wrench. The disclosure provides a torque value setting method and system of a torque wrench and a server. The following detailed description is made with reference to the accompanying drawings which respectively illustrate embodiments provided by the present disclosure.
Fig. 1 is a flowchart illustrating a torque value setting method of a torque wrench according to an embodiment of the present disclosure. The torque value setting method of the torque wrench can be applied to a server. As shown in fig. 1, the method for setting the torque value of the torque wrench provided in the present embodiment includes the following steps.
Step S101 is to receive the head images of the torque wrenches transmitted from the imaging device.
And S102, determining the torque wrench with the torque value to be adjusted in response to determining that the head space position of the torque wrench is overlapped with the space position of the work station according to the head image of each torque wrench, the pre-stored work station image and the pre-stored factory image.
Step S103, determining a preset torque value of the torque wrench to be adjusted corresponding to the station.
Step S104, sending a torque value setting command including a preset torque value to the torque wrench to be adjusted, so that the torque wrench to be adjusted sets the torque value to the preset torque value.
According to the torque value setting method of the torque wrench, factory images and station images in a factory are stored in a server in advance, head images of the torque wrench are shot by camera devices located around the torque wrench and sent to the server, and if the server determines that the head space position of the torque wrench is overlapped with the space position of a station according to the head images of the torque wrench, the pre-stored station images and the pre-stored factory images, the server determines the torque wrench with a torque value to be adjusted. The torque wrench for determining the torque value to be adjusted has two meanings, namely, the torque wrench for determining the torque value to be adjusted is determined as the torque wrench for determining the torque value to be adjusted when only the head space position of one torque wrench is overlapped with the space position of a station; and secondly, determining that the head space positions of the plurality of torque wrenches are overlapped with the space positions of the plurality of stations, and selecting one torque wrench from the plurality of torque wrenches as the torque wrench to be adjusted in torque value. The torque value matched with each station is preset in the server. After the server determines the torque wrench with the torque value to be adjusted, the server determines a preset torque value matched with the corresponding station of the torque wrench with the torque value to be adjusted, and sends a torque value setting instruction including the preset torque value to the torque wrench with the torque value to be adjusted, so that the torque wrench with the torque value to be adjusted sets the torque value as the preset torque value.
In the embodiment of the disclosure, the server can automatically determine the torque wrench to be adjusted and the preset torque value of the torque wrench to be adjusted, and send the torque value setting instruction including the preset torque value to the torque wrench to be adjusted, and the torque wrench to be adjusted sets the torque value as the preset torque value of the corresponding station. The method for automatically adjusting the torque value of the torque wrench does not need to match the preset torque value with the station aiming at the bolts of a specific category, so that the corresponding station can achieve the fastening effect, the fastening effect can meet the requirement of the station, and a factory is not damaged. Meanwhile, the factor of manual operation error is eliminated, and the production efficiency is improved.
Fig. 2 illustrates an alternative implementation manner provided by the embodiment of the present disclosure, in which the spatial position of the head of the torque wrench is determined to overlap with the spatial position of the work station in step S102 in fig. 1. The disclosed embodiments include two cases, namely, the spatial position of the head of one torque wrench overlaps the spatial position of one workstation, and the spatial positions of the heads of multiple torque wrenches overlap the spatial positions of multiple workstations. In the following embodiments, the spatial positions of the heads of the two torque wrenches are overlapped with the spatial positions of the two stations.
In some embodiments, as shown in fig. 2, in the step S102, it is determined that the spatial position of the head of the torque wrench overlaps the spatial position of the work station according to the head image of the torque wrench, the pre-stored images of the work stations, and the pre-stored factory image, including;
in step S201, a first plan view including each torque wrench and a factory is drawn according to a head image of each torque wrench and a pre-stored factory image.
As shown in fig. 3, the factory plane includes a workpiece, and the workpiece includes three stations (station 1, station 2, and station 3), and two stations (station 2 and station 3) are respectively provided with a torque wrench. The head images of the torque wrenches are the head image of the torque wrench 1 and the head image of the torque wrench 2, and a first plan view is drawn according to the head images of the torque wrench 1 and the torque wrench 2 and a pre-stored factory head image, as shown in fig. 4, in the first plan view, the head space position of the torque wrench 1 and the head space position of the torque wrench 2 are overlapped to form an area of one station.
And S202, determining that the head space position of the torque wrench is overlapped with the space position of the work station according to the first plane view and the preset second plane view.
The second plan view comprises all stations and factories and is obtained by the server through drawing according to pre-stored station images and pre-stored factory images. As shown in fig. 5, in the second plan view, the spatial position of the station 2 and the spatial position of the station 3 overlap as the area of one station.
In this step, as can be understood from a comparison of fig. 4 and 5, the head space position of the torque wrench 1, the head space position of the torque wrench 2, the space position of the station 2, and the space position of the station 3 overlap as a region of one station.
In a preferred embodiment, the server may not include the station images, the factory image, and the second plane image drawn according to the station images and the factory image in advance, the camera device sends the station images and the factory image to the server, and the server determines the position of the stations in the space, the position of the workpiece in the factory, and the like according to the received station images and the factory image, and redraws a new second plane image. The workstations in the factory may move in a limited range, and when the method is applied to a scene in which the workstations move, the server can draw a new second plan view by adopting a mode that the camera device shoots images of all the workstations and images of the factory and sends the images to the server.
In some embodiments, the determining the torque wrench with the torque value to be adjusted in response to determining that the spatial position of the head of the torque wrench overlaps with the spatial position of the work station according to the head image of the torque wrench, the pre-stored images of the work stations, and the pre-stored factory image (i.e., step S102) includes:
and responding to the area that the head space positions of the plurality of torque wrenches and the space positions of the plurality of stations are overlapped into one station according to the head images of the torque wrenches, the pre-stored station images and the pre-stored factory images, and selecting the torque wrench with the torque value to be adjusted from the torque wrenches.
As shown in fig. 4 and 5, the spatial positions of the head of the torque wrench 1, the head of the torque wrench 2, the spatial position of the station 2, and the spatial position of the station 3 overlap to form a region of one station, and the torque wrench whose torque value is to be adjusted can be selected from the torque wrench 1 and the torque wrench 2.
Fig. 6 illustrates an alternative embodiment of a torque wrench for selecting a torque value to be adjusted from a plurality of torque wrenches provided by an embodiment of the present disclosure. In the embodiment of the present disclosure, a torque wrench to be adjusted is selected from two torque wrenches.
In some embodiments, the selecting a torque wrench to be adjusted in the step S102 from a plurality of torque wrenches includes:
step S301, sequentially sending an indicator light flashing command to a plurality of torque wrenches.
Step S302, sequentially receiving the indicator light flashing images of the plurality of torque wrenches sent by the camera device.
Step S303, determining the mapping relation between the plurality of torque wrenches and the stations according to the flashing images of the indicator lights of the plurality of torque wrenches.
Step S304, selecting a torque wrench with a torque value to be adjusted from the plurality of torque wrenches according to the mapping relationship between the plurality of torque wrenches and the work station.
As shown in fig. 7, the indicator light in the disclosed embodiment is located at the head of the torque wrench. As shown in fig. 2, when the server sequentially sends an indicator light flashing command to the torque wrench 1 and the torque wrench 2, the server sequentially receives an indicator light flashing image of the torque wrench 1 and an indicator light flashing image of the torque wrench 2 sent by the camera, determines the position of the torque wrench 1 in the space and the station corresponding to the position in the space as the station 3 according to the indicator light flashing image of the torque wrench 1, and determines the position of the torque wrench 2 in the space and the station corresponding to the position in the space as the station 2 according to the indicator light flashing image of the torque wrench 2. Therefore, the mapping relationship between the torque wrenches and the work positions is determined from the torque wrench 1 to the work position 3, and from the torque wrench 2 to the work position 2. And determining which station needs to be operated according to the requirements of the user, and determining the torque wrench corresponding to the station as the torque wrench of which the torque value is to be adjusted according to the mapping relation.
It should be noted that only when the mapping relationship between the station and the torque wrench is determined, the preset torque value matched with the station can be determined, and the torque value matched with the station is sent to the torque wrench corresponding to the operation, so as to complete the automatic setting of the proper torque value for the torque wrench. The situation that a higher torque value is possibly damaged by a factory or a lower torque value cannot meet the fastening requirement of a station is avoided.
In a preferred embodiment, the server may issue an indicator light flashing command from any one of the torque wrenches, and when the server receives an indicator light flashing image of the torque wrench sent by the camera, the server determines the position of the torque wrench in the space, that is, determines which station the torque wrench corresponds to. The preset torque value of the station can be obtained, a torque value setting instruction comprising the preset torque value is sent to the torque wrench corresponding to the station, and only the torque value of the torque wrench is adjusted.
In some embodiments, the method further comprises:
and responding to the fact that the head space position of the torque wrench is not overlapped with the space position of the work station according to the head images of the torque wrenches, the pre-stored work station images and the pre-stored factory images, and sending a reset torque value setting instruction comprising a torque value of zero to the torque wrench with the torque value to be adjusted.
In the embodiment of the present disclosure, the torque value of the torque wrench is zero by default, that is, the torque wrench can only idle and cannot apply pressure to the bolt, and the torque value of the torque wrench when leaving the station is also reset to zero. The effect is, avoid system mistake to result in applying incorrect torque value to certain station and damaging the work piece or make the station fastening substandard.
In a preferred embodiment, after the torque wrench has performed the step of setting the torque value, a beep (e.g., beeping briefly twice) may be issued to prompt the worker that the torque value has been set, whereby the worker may perform the tightening operation. After the worker completes the tightening operation, the torque wrench is removed from the tightening station. The server determines that the head space position of the torque wrench is not overlapped with the space position of the station, and sends a reset torque value setting instruction comprising a torque value of zero to the torque wrench. When the torque value of the torque wrench is reset to zero, the beep may be re-sounded (e.g., a single prolonged sound) to prompt the worker that the torque is reset to zero. When the worker places the torque wrench on a certain work station again, the server performs the steps S101 to S104 again.
In the embodiment of the disclosure, the sleeve can be a sleeve with a single bolt size or a universal sleeve, namely, a sleeve capable of automatically matching various bolt sizes. Especially, when being applicable to the sleeve and being omnipotent sleeve, can accomplish and need not change torque wrench, the server stores a plurality of torque value of a station in advance, can realize carrying out the fastening operation to the station of a plurality of different torque values, obviously promotes work efficiency. Otherwise, the worker must at least manually switch between different torque values to perform the tightening operation for the different torque values, which increases the possibility of human error.
