[0042] Example 1

[0043] See also Figure 1-Figure 5This embodiment provides a measuring device for a hydraulic press workbench, including a base 100, two brackets 200 for support are symmetrically fixed on the upper surface of the base 100, a middle rail 300 is embedded between the two brackets 200, and an automatic measuring device 400 is connected to the bottom of the middle rail 300 through a driving mechanism. The automatic measuring device 400 is a disclosed technology (specifically, the disclosed technology in CN113310462B), and is only used as one of the necessary tools for measurement in this application;

[0044] The top ends of the two brackets 200 are both provided with a hoisting assembly 500, and the two hoisting assemblies 500 are symmetrically arranged around the center of the middle rail 300;

[0045] The hoisting assembly 500 in the present application includes: a winding bin 530, a battery 570, and an inclined support rod 520. The winding bin 530 is fixed at the top of the bracket 200, and a steel cable 540 is wound on the internal winding wheel of the winding bin 530. A hollow shell 550 is fixed at the end of the steel cable 540 away from the winding bin 530. The rise and fall of the hollow shell 550 are controlled by the retraction and extension of the steel cable 540. An iron core 551 is fixed inside the hollow shell 550, and a solenoid 552 is arranged outside the iron core 551, and the two ends of the solenoid 552 are electrically connected to the positive and negative poles of the battery 570 respectively. When the solenoid 552 is energized, the iron core 551 will be magnetized by the magnetic field generated by the energized solenoid 552, so that the iron core 551 has a strong magnetic attraction effect. In order to make the electromagnet demagnetized immediately when the power is cut off, the iron core 551 in the present application is made of soft iron or silicon steel material with faster demagnetization. Such an electromagnet is magnetic when powered on, and the magnetism disappears when the power is turned off. The battery 570 is fixed to the side of the bracket 200 through the tilting support rod 520. The top of the tilting support rod 520 is rotatably connected to a guide wheel 560 of a steel cable 540 for guiding. Through the setting of the guide wheel 560, the part of the steel cable 540 after passing through the guide wheel 560 is in a vertical state. A first rotating rod 561 is fixed to the side of the guide wheel 560. The first rotating rod 561 penetrates the tilting support rod 520 and is located outside the tilting support rod 520. Figure 4 As shown, a first push switch 580 is disposed at the top of the battery 570, and a groove 541 is provided on one side of the steel cable 540 close to the first push switch 580 in the initial state, and the first push switch 580 is located in the groove 541;

[0046] The dual-axis motor 510 is a remotely controllable dual-axis motor 510, which is fixed to the top of the bracket 200, and the two output shafts of the dual-axis motor 510 are respectively connected to the winding wheels in the two winding bins 530 to drive the winding wheels to rotate. The battery 570 is electrically connected to the dual-axis motor 510 through a wire 571. When the dual-axis motor 510 is connected to an external power source, it will conduct part of the electricity to the battery 570 and store it during operation. By setting two sets of hoisting components 500, the hydraulic press workbench is positioned and hoisted in a four-corner positioning manner. At the same time, the connection between the hoisting component 500 and the hydraulic press workbench is connected by an electromagnet adsorption method, so that while ensuring stable hoisting, it will not cause damage to the surface of the hydraulic press workbench, thereby solving the problem of unstable single-point hoisting proposed in the background technology, which affects the measurement accuracy.

[0047] When the hydraulic press workbench is hoisted and measured in the present application, the specific application of the hoisting assembly 500 is as follows: first, the hydraulic press workbench to be measured is placed on the base 100, and then the two dual-axis motors 510 are remotely controlled to work synchronously, and the output shaft of the dual-axis motor 510 is used to control the rotation of the winding wheel in the winding bin 530. Under the self-weight of the hollow shell 550 and the iron core 551, the steel cable 540 is released. At this time, the four hollow shells 550 and the iron core 551 move downward at the same time. When the steel cable 540 is released, the first push-type switch 580 located at the bottom of its groove 541 is squeezed due to the movement of the steel cable 540. At this time, the battery 5 70 pairs of solenoids 552 are powered. When the solenoids 552 are powered, the iron cores 551 are magnetized by the magnetic field generated by the powered solenoids 552, so that the iron cores 551 have a strong magnetic attraction effect. The four iron cores 551 adsorb the four corners of the hydraulic press workbench to be measured. At this time, the two dual-axis motors 510 are remotely controlled to rotate in opposite directions, so that the four winding wheels in the two hoisting components 500 rotate synchronously. At this time, the four steel cables 540 simultaneously pull the four hollow shells 550 and the iron cores 551 upward. At this time, the hydraulic press workbench to be measured is lifted. After moving to a suitable height, the surface of the hydraulic press workbench to be measured is measured by the automatic measuring device 400;

[0048] After the measurement is completed, the steel cable 540 is controlled to move downward by the two double-axis motors 510, and the hydraulic press workbench after measurement is placed above the base 100. At this time, the power supply of the two double-axis motors 510 is disconnected to cut off the power supply of the equipment. In the absence of an external power supply, the solenoid 552 loses current, and the iron core 551 loses its magnetism. Then the hydraulic press workbench is taken out, and finally the two double-axis motors 510 are connected to an external power supply, and the equipment is reset by the two double-axis motors 510. When the steel cable 540 is completely restored to the state as shown in the figure, the hydraulic press workbench is removed. Figure 3When the state is reached, the first push switch 580 at the top of the battery 570 is released, and the magnetism of the iron core 551 disappears, and the measurement operation of the single hydraulic press workbench is completed.

[0049] See also Figure 1 , Figure 7 , Figure 8 , Fig. 9 , waste slag recovery components 700 are arranged on both sides of the middle rail 300, and the waste slag recovery components 700 include two groups of rails 710 fixed on the side of the middle rail 300, and a concave wheel disc 720 rotatably connected to the side of the middle rail 300, and L-shaped slide bars 730 are slidably connected in the two groups of rails 710, and a slide groove 731 is opened on the side of each L-shaped slide bar 730, and a recovery bin 740 is slidably connected to the side of each L-shaped slide bar 730 through the slide groove 731, and two ropes 750 for pulling the L-shaped slide bar 730 to move are symmetrically fixed in the concave wheel disc 720, and a second rotating rod 760 is fixed on the outside of the concave wheel disc 720, and the second rotating rod 760 is transmission-connected to the first rotating rod 561 through a transmission belt 770, and a spring 780 is fixed between the L-shaped slide bar 730 and the rail 710.

[0050] In a specific application, the waste residue recovery assembly 700 is located at Figure 1 In the state, the recovery bin 740 is located at the bottom of the iron core 551, and when the iron core 551 is converged to Figure 1 When the magnetism disappears, the iron-containing impurities attached to it will fall into the recovery bin 740, which is convenient for the recovery of the iron-containing impurities.

[0051] In the present application, when the hoisting assembly 500 is working, since the second rotating rod 760 is connected to the first rotating rod 561 in the hoisting assembly 500 through the transmission belt 770, when the steel cable 540 is released, the steel cable 540 moves, so the guide wheel 560 rotates, and then the first rotating rod 561 fixed on its side follows the rotation. At this time, the second rotating rod 760 is driven to rotate under the action of the transmission belt 770. At the same time, since the second rotating rod 760 rotates, the concave wheel disc 720 fixedly connected thereto rotates. When the concave wheel disc 720 rotates, The two wire ropes 750 will be reeled in at the same time. By reeling in the two wire ropes 750, the two L-shaped slide bars 730 will be pulled at the same time to drive the recovery bin 740 to move, so as to prevent the recovery bin 740 from affecting the downward movement of the hollow shell 550 and the iron core 551. When the steel cable 540 is reeled in to drive the hollow shell 550 and the iron core 551 to reset, the guide wheel 560 will rotate in the opposite direction. At this time, the concave wheel disc 720 releases the wire rope 750. At the same time, under the action of the rebound force of the spring 780, the L-shaped slide bar 730 and the recovery bin 740 are pushed to reset until the recovery bin 740 is directly below the iron core 551.

[0052] See also Figure 1 and Figure 6 A brush assembly 600 is arranged at the bottom of the battery 570, and the brush assembly 600 includes a rotating motor 610, wherein the rotating motor 610 is electrically connected to the battery 570, and a second push-type switch 640 is arranged on the side of the rotating motor 610, and a disk 620 is fixed on the output shaft at the bottom of the rotating motor 610, and at least one brush roller 630 is rotatably connected to the side of the disk 620 in a circular array, and the second push-type switch 640 is located above the hollow shell 550, and a gap is left between the hollow shell 550 and the second push-type switch 640.

[0053] When the brush assembly 600 is used in a specific application, after the measurement operation is completed, the hoisting assembly 500 is restored to the position as shown in FIG. Figure 1 In the state shown, the double-axis motor 510 is turned on again to reel in the steel cable 540, so that the steel cable 540 drives the hollow shell 550 to move upward again until the top of the hollow shell 550 squeezes the second push-type switch 640. At this time, the double-axis motor 510 is turned off to position the hollow shell 550. At this time, due to the movement of the steel cable 540, the first push-type switch 580 is squeezed to energize the battery 570, and then the battery 570 supplies power to the rotating motor 610. When the second push-type switch The switch 640 is squeezed, the rotating motor 610 rotates, and the output shaft at the bottom thereof controls the disc 620 to rotate. At this time, the multiple brush rollers 630 outside the disc 620 rotate to clean the bottom of the hollow shell 550 and the iron core 551, so as to clean the non-iron-containing attached waste slag to ensure that there is no debris adsorbed on the bottom of the hollow shell 550 and the iron core 551, so that the contact with the hydraulic press workbench is clean and tidy during subsequent use, thereby further improving the measurement accuracy of the hydraulic press workbench.
