Description
Technical Field
The invention belongs to the technical field of mechanical equipment, and particularly relates to automatic detection equipment for testing the performance of an electric wrench.
Background
The electric impact wrench refers to a hand-held tool which takes an alternating current power supply or a battery as a power source to tighten and disassemble a threaded fastener. The electric wrench is an indispensable and irreplaceable special tool for screwing bolts in various operation occasions due to small volume, light weight, convenient carrying, simple and rapid operation, safety and reliability. Research shows that the electric impact wrench is widely applied to the fields of machinery manufacturing industry, construction industry, traffic construction engineering, forestry, home decoration service and the like. The electric wrench greatly reduces the labor intensity, improves the working efficiency and realizes the mechanization of manual operation, thereby being popular with people. The torque wrench can visually display the torque value generated by the torque wrench so as to ensure the accuracy of threaded connection. The torque wrench is a novel device integrating 'tools-instruments', and is widely applied to the manufacturing aspects of aviation, aerospace, ships, automobiles, petrifaction, precision machinery and precision instruments. At present, the annual production of torque wrenches in China is about ten tens of thousands, and millions of torque wrenches are in use.
According to investigation, some problems are often encountered in the daily use of the electric wrench. Such as torque, that does not meet the bolt tightening or removal requirements. When the bolt is screwed down, the bolt connection is unreliable due to insufficient torque, and safety risk exists; when the bolt is disassembled, the bolt is difficult to unscrew due to insufficient torque, and the bolt can be disassembled by using a repeated tool or even by using other manual wrenches with large force arms. In addition, people often complain that tightening a set of bolts takes a lot of time than others use, and the work efficiency is not satisfactory. The most serious problem is that some critical parts of the tool fail after a period of use and the tool cannot continue to operate. Therefore, in order to ensure that the electric wrench normally operates, the wrench tester is required to be used for detecting the electric wrench, and the main same type of verification instruments of the current torque wrench verification instrument comprise the following instruments: 1. mechanical torque wrench detector. The instrument has the advantages of simple structure, small volume, light weight of 9.6kg, high accuracy, measurement error less than 0.8%, resolution up to 0.1N.m, low cost and convenient carrying. The device is suitable for calibrating the fixed values of various torque wrenches, calibrating torque errors, debugging and checking torques and the like; 2. electronic torque wrench calibrator. The calibrator has the characteristics of complex structure, large volume, weight of 60kg, accuracy of 1.5 percent and resolution of 1 N.m; 3. single chip microcomputer torque wrench calibrator. The calibrating instrument can correct calibration errors by using the calculation control function of a computer, can display various metering units, and can select a continuous display mode or a maximum value display mode to eliminate artificial reading errors. The assay accuracy is +/-0.5%, and the resolution is 0.1N.m. Therefore, most of the existing torque wrench calibrating instruments are still mechanical, and the electronic torque wrench calibrating instrument and the single chip microcomputer torque wrench calibrating instrument are greatly limited by the use environment. Moreover, the calibration accuracy, the detection efficiency and the functions of the conventional torque wrench calibration equipment cannot meet the requirements of the conventional torque wrench on production and use.
In order to solve the defects of the prior art, people have long searched for and put forward various solutions. For example, chinese patent literature discloses a dynamic torque testing stand [201620433362.4] for a bolt wrench, which is connected to a bolt wrench to be tested, and is characterized in that the testing stand includes a connection sleeve, a reversing gear box, a brake, a coupling, and a measurement sensor, the reversing gear box is connected to the connection sleeve and the brake through the coupling, the measurement sensor is installed on the coupling between the reversing gear box and the connection sleeve, and the connection sleeve is connected to the bolt wrench to be tested.
The scheme solves the problem of low calibration accuracy of the wrench calibration equipment in the prior art to a certain extent, but the scheme still has a plurality of defects, such as: low detection efficiency, single detection function, low automation degree and the like.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

Obviously, in this embodiment, the wrench to be tested 6 may be connected to the detecting lifting seat 23 in a clamping manner, for example, a plurality of clamping holes may be formed in the detecting lifting seat 23 for installing the wrench to be tested 6.
The reason why the detection efficiency needs to be improved is that the current electric wrench mainly uses the servo motor and the planetary gear as main power transmission components, and domestic researches on the servo motor and the planetary gear are very deeply researched. Due to the compact structure of the electric wrench and the high requirement of the rotating speed and torque ratio, a micro planetary gear is usually used as a component for torque transmission. For technical reasons, a plurality of instruments are widely used in the market to separately detect a plurality of detection items. Because the number of detection items is large, each detection instrument needs to be equipped with one person for detection in a manual detection mode, the whole detection requirement needs a plurality of workers, the number of the workers can only be completely accumulated for enterprises with large output, the labor cost can be increased due to the fact that the workers use the manpower for a long time, and the labor cost is large for the enterprises; and because of the productivity needs, every instrument of manual detection all needs to be equipped with the personnel of the supplies to carry out the product material loading to it. In addition, visual or auditory fatigue can be generated after manual detection for a long time, and the problem of product quality reduction caused by human factors can be generated; the manual operation has too many uncertain factors and has poor control on quality, productivity and the like. However, the fixed speed-torque ratio cannot be accurately realized because the related data of the rotating speed and the torque cannot be accurately acquired. And through the dual joint structure in duplex position, adopt the integrated detection device design of double rotational speed moment of torsion in this implementation, realize simultaneously detecting two electric spanner, full automation has improved detection precision and detection efficiency.
Specifically, the regulation detection system 3 includes a PLC configuration control device 31, and the PLC configuration control device 31 is connected to the upper computer 32.

The software such as PLC, VB/LabVIEW and the like is adopted for development, so that the intelligent detection system has the functions of operation monitoring, safety alarm, parameter setting, visual display and the like, realizes the intelligent detection function, and can realize continuous operation.
The measured voltage and current signals are analog signals, which cannot be directly processed by data operation, and must be converted into digital signals through analog-to-digital conversion, and the digital signals can be sent into the controller after being digitally filtered. Then, the relationship n between the motor rotation speed n and the frequency f is 60f/p (p is the number of pole pairs), and the rotation speed can be obtained by sending the frequency measured when the electric wrench is operated to the control chip for processing. The alternating signal output by the rotating speed measuring part can be processed to obtain an ideal pulse signal, and the rotating speed of the motor can be indirectly measured by performing frequency calculation on the detected periodically-changed pulse signal. The system adopts a method of counting pulses by a timer and an external interrupt at the same time to measure the frequency of the motor.
In this embodiment, the regulation and control detection system 3 adopts the design of PLC configuration control and upper computer interface, sets up a real-time transmission system for device detection data, embeds each detection data conversion program and protection circuit, completes the acquisition of torque data through pressure detection, and through the threshold detection of parameters such as pressure and current, avoids the problems such as excessive beating of the electric wrench, and realizes high-precision and high-efficiency detection.
