DETAILED DESCRIPTION
[0019] The present invention will be further described below with reference to the accompanying drawings.
[0020] like Figure 1 As shown, a pressure sensing structure 5 is provided inside the press 4. A pressure column 5.7 is connected below the pressure sensing structure 5. The pressure column 5.7 is used to fix the workpiece 8 from above. At the same time, when the press 4 is pressed down, the pressure column 5.7 transmits the pressure to the workpiece 8. One side of the pressure sensing structure 5 is connected to a sliding block 6. The sliding block 6 is slidably connected to a strip displacement sensor 7. Figure 2As shown, the pressure sensing structure 5 includes a pressure sensor upper plate 5.1, a pressure sensor lower plate 5.2, a pressure sensor 5.3, a pressure hard block 5.4, a guide column and guide sleeve 5.5, and a device base 9. The device base 9 is connected to the sliding block 6. The lower part of the device base 9 is connected to the pressure sensor upper plate 5.1, and the lower part of the pressure sensor upper plate 5.1 is connected to the pressure sensor lower plate 5.2. Figure 4 As shown, the pressure sensor 5.3 is provided on the upper plate 5.1 inside the pressure sensor. Figure 3 As shown, the lower surface of the pressure sensor lower plate 5.2 is provided with a pressure hard block 5.4 that cooperates with the pressure sensor 5.3, and guide pillars and guide sleeves 5.5 are provided around the pressure hard block 5.4. The pressure sensor upper plate 5.1 is provided with a guide hole 5.6 that cooperates with the guide pillars and guide sleeves 5.5. The strip displacement sensor 7 and the pressure sensor 5.3 can record the pressure data received by the workpiece and the displacement deformation generated synchronously in real time. The four guide pillars and guide sleeves 5.5 cooperate with the guide holes 5.6 to ensure the reliability and stability of the overall structure when the tooling is floating. The pressure hard block 5.4 can provide support and protection for the sensor, while enhancing the stability and durability of the sensor.
[0021] A force displacement controller 1 is provided outside the press 4 , which outputs an analog electrical signal according to the induction of the workpiece 8 on the pressure sensing structure 5 and the strip displacement sensor 7 . The press 4 presses down the workpiece 8 upon receiving the analog electrical signal.
[0022] A host computer 2 is provided outside the press 4, and the host computer 2 is connected to the strip displacement sensor 7, the pressure sensor 5.3, and the force-displacement display screen 3. The host computer 2 is responsible for storing data and displaying the force-displacement curve through the force-displacement display screen 3.
[0023] Protective nets 13 are provided on both sides of the press 4 .
[0024] A fixing plate 4.1 is provided on the upper surface of the press 4. One end of the workpiece 8 is inserted into the fixing plate 4.1, and the other end of the workpiece 8 is inserted into the pressurizing column 5.7. The fixing plate 4.1 is a replaceable structure. When fixing the monitored workpiece 8, a fixing plate 4.1 that can fit the workpiece 8 is selected.
[0025] like Figure 5 As shown, a T-shaped pin 11 is embedded in the device base 9, the T-pin is connected to one end of a stud 12, and the other end of the stud 12 passes through the pressure sensor upper plate 5.1 and is connected to the pressure sensor lower plate 5.2.
[0026] A waste box 10 is provided on the side of the press 4 .
[0027] The specific implementation process of the present invention is as follows: the technician clamps one end of the workpiece 8 in the sliding block and inserts the other end into the pressure column 5.7 for fixation, operates the force displacement controller 1 to control the press 4 to press down, and the sliding block 6 slides on the strip displacement sensor 7. The downward force of the press 4 will be transmitted to the workpiece 8 through the pressure column 5.7. The pressure sensor 5.3 and the strip displacement sensor 7 respectively record the pressure on the workpiece 8 and the displacement of the press 4, and generate a force displacement curve in real time. The curve is stored and transmitted to the force displacement display screen 3 for real-time display through the host computer 2. The force displacement curve is analyzed to see whether it is normal. Unqualified parts are directly placed in the waste bin by manual or mechanical means. The host computer 2 can normally store the force displacement curves of all different workpieces 8 for more than 3 years. The host computer 2 can also read and conduct further analysis. Based on this function, qualified force displacement curves of more than 60 products can be recorded. If multiple workstations are set up, multiple workpieces can be monitored simultaneously by reading different data. Different products can also be monitored by replacing the fixed plate 4.1. The monitoring effect of the present invention is intuitive, the process is fast, and the operation is simple.
