[0016] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0017] See also Figure 1-7 The present invention provides a diameter measuring device for processing the piston of a six-sided top press, comprising a measuring ring 1 and a gear box 5 fixedly arranged at the bottom of the measuring ring 1, four evenly distributed limit slides 2 are fixedly arranged on the outside of the measuring ring 1, an upper slide groove 4 is provided in the middle of the top of the limit slide 2, four lower slide grooves 20 are provided on the inner side of the measuring ring 1, a piston centering mechanism 3 for measuring the six-sided top press is installed between the upper slide groove 4 and the lower slide groove 20, a transmission cavity 18 is provided inside the measuring ring 1, a transmission gear ring 15 is rotatably provided inside the transmission cavity 18, a gear warehouse 14 is provided inside the gear box 5, a driving mechanism for driving the transmission gear ring 15 to rotate is fixedly installed inside the gear warehouse 14, a handle assembly is fixedly installed on the bottom end of the gear box 5, a laser ranging sensor 9 is fixedly installed on one side of the top of the four limit slides 2, and a single-chip controller 8 is fixedly installed on the back of the gear box 5.

[0018] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4 Furthermore, the piston centering mechanism 3 includes a measuring slide 31 and a probe 36 fixedly arranged at the bottom end of the measuring slide 31, a side rack 32 is fixedly arranged on one side of the measuring slide 31, and a gear assembly for driving the measuring slide 31 to move is meshed and connected on one side of the side rack 32, a slide rail 37 is fixedly arranged on the front of the measuring slide 31, and the slide rail 37 is slidably arranged on the limit slide 2, and a reflective plate 33 is fixedly arranged on the other side of the measuring slide 31, a laser ranging sensor 9 is arranged opposite to the reflective plate 33, and the laser ranging sensor 9 is electrically connected to the single-chip controller 8, a pressure sensor 38 is fixedly installed at the bottom end of the probe 36, and the pressure sensor 38 is electrically connected to the single-chip controller 8, the probe 36 is arranged in an arc shape, and the measuring ring 1 and the four probes 36 are cocentric; During use, the piston to be measured is centered by four probes 36, and the laser ranging sensor 9 measures the distance to the reflector 33 in real time to determine the displacement change until the four pressure sensors 38 simultaneously sense that the pressure stops. The measurement result is obtained through the displacement change, without the need for manual reading, and is more accurate.

[0019] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4 Furthermore, the gear assembly includes a center gear 35, a center shaft 39 is fixedly provided in the middle of the center gear 35, a driven gear 34 is fixedly provided on the center shaft 39, one side of the driven gear 34 is meshed and connected with the inner side of the transmission gear ring 15, and the center shaft 39 is rotatably provided inside the transmission cavity 18; During use, the transmission ring gear 15 will drive the driven gear 34 to rotate, and then drive the center gear 35 to rotate through the center shaft 39. Since the measuring slide 31 is meshed and connected to the center gear 35 through the side rack 32, when the center gear 35 rotates, the measuring slide 31 will push the measuring head 36 close to or away from the six-sided top press piston to be measured, thereby realizing the centered measurement of the piston to be measured, which is beneficial to reduce errors in the measurement process and improve the accuracy of the measurement.

[0020] See Figure 1 、 Figure 2 、 Figure 3 and Figure 7 Furthermore, the driving mechanism includes a servo motor 12 and a worm 13 fixedly mounted on the output end of the servo motor 12. One side of the worm 13 is meshedly connected with a worm wheel 17. A concentric shaft 19 is fixedly provided in the middle of the worm wheel 17. A driving wheel 16 is fixedly provided on the concentric shaft 19. One side of the driving wheel 16 is in contact with the outer side of the transmission gear ring 15. The servo motor 12 is electrically connected to the single-chip controller 8. During use, the servo motor 12 will work during the measurement process, driving the worm 13 to rotate, and the worm 13 drives the worm wheel 17 to rotate, and then drives the driving wheel 16 to rotate slowly through the concentric shaft 19. Since the driving wheel 16 is close to the transmission gear ring 15, under the action of friction, the transmission gear ring 15 will also rotate slowly, thereby causing the four piston centering mechanisms 3 to move synchronously, realizing the centering fixation of the piston. After the measurement is completed, the servo motor 12 reverses, and the four piston centering mechanisms 3 are reset, and then the next measurement work can be carried out, which is beneficial to improving the efficiency of the measurement.

[0021] See Figure 1 and Figure 2Furthermore, the grip assembly includes a measuring grip 6 and a battery 10 fixedly installed inside the measuring grip 6. A charging port 11 is fixedly installed at the bottom end of the measuring grip 6, and the charging port 11 is electrically connected to the battery 10. A control panel 7 is fixedly installed on the front of the gear box 5. A touch display, a power switch, a calibration switch, and a reset button are fixedly installed on the surface of the control panel 7. The touch display is electrically connected to the single-chip controller 8, and the single-chip controller 8 is electrically connected to the battery 10 through the power switch. The surface of the measuring grip 6 is covered with an anti-slip rubber sleeve 21. When in use, the measuring device is powered by the battery 10. The overall design is compact, and the staff only needs to hold the measuring handle 6 to perform normal measurement operations. It is portable, practical and low-cost.

[0022] When using the embodiment of the present application: first stop the lathe processing the piston, wait for the clamped six-sided top press piston to stop rotating, then the staff member holds the non-slip rubber sleeve 21, puts the measuring ring 1 on the surface of the piston to be measured, moves it to the measuring position, and starts the measuring device by turning on the power switch. At this time, the servo motor 12 will work, driving the worm 13 to rotate, and the worm 13 drives the worm wheel 17 to rotate, and then drives the drive wheel 16 to rotate slowly through the concentric shaft 19. Since the drive wheel 16 is in close contact with the transmission gear ring 15, the transmission gear ring 15 will also rotate slowly under the action of friction, and the four piston centering mechanisms 3 are driven to move simultaneously through the transmission gear ring 15; When the piston centering mechanism 3 is working, the transmission gear ring 15 will drive the driven gear 34 to rotate, and then drive the centering gear 35 to rotate through the central shaft 39. Since the measuring slide 31 is meshed with the centering gear 35 through the side rack 32, when the centering gear 35 rotates, the measuring slide 31 will push the probe 36 to approach or move away from the six-sided top press piston to be measured. The four probes 36 move simultaneously, thereby centering the six-sided top press piston in the middle of the measuring ring 1. During this process, the four laser ranging sensors 9 will measure the distance to the reflector 33 in real time to determine the displacement change X until the four pressure sensors 38 simultaneously sense that the pressure stops. The inner diameter of the measuring ring 1 is 1000mm, and the measured piston diameter is 1000-2Xmm. Four sets of readings can be measured simultaneously, and the measurement results can be read directly through the touch screen, which is conducive to reducing the measurement error. After the measurement is completed, press the reset button. At this time, the servo motor 12 reverses, the four piston centering mechanisms 3 are reset, and then the next measurement can be carried out.
