DETAILED DESCRIPTION

[0024] The technical solutions and technical effects of the embodiments of the present invention are further described in detail below in conjunction with the accompanying drawings of the present invention.

[0025] Please see Figure 1 A square rod auxiliary detection device includes a workbench 10, on which a first clamping mechanism 20, a second clamping mechanism 30, a first moving mechanism 40, and a second moving mechanism 50 are symmetrically arranged. The first clamping mechanism 20 is slidably mounted on the first moving mechanism 40 through a first mounting frame 60, and the second clamping mechanism 30 is slidably mounted on the second moving mechanism 50 through a second mounting frame 70, so as to drive the first clamping mechanism 20 and the second clamping mechanism 30 to move to a suitable position through the first moving mechanism 40 and the second moving mechanism 50; the first clamping mechanism 20 includes a first clamping assembly 21, a first rotating assembly 22, and a first lifting assembly 23, and the second clamping mechanism 30 includes a second clamping assembly 31, a second rotating assembly 32, and a second lifting assembly 3, wherein the first clamping assembly 21 and the second clamping assembly 31 are used to clamp and fix both ends of the square rod, the first lifting assembly 22 and the second lifting assembly 32 are used to lift the fixed square rod to a set height for convenient detection of the square rod, and the first rotating assembly 23 and the second rotating assembly 33 are used to rotate the square rod.

[0026] First, according to the length of the square rod, the first moving mechanism 40 is controlled to drive the first clamping mechanism 20 to move, and the second moving mechanism 50 is controlled to drive the second clamping mechanism 30. When the first clamping mechanism 20 and the second clamping mechanism 30 are moved to a suitable position, the square rod is placed on the first clamping mechanism 20 and the second clamping mechanism 30, and the left end of the square rod is clamped and fixed by the first clamping assembly 21, and the right end of the square rod is clamped and fixed by the second clamping assembly 22. Then, the first lifting assembly 23 and the second lifting assembly 33 are controlled to rise at the same time, so as to drive the square rod to rise to a set height, and the inspection personnel use the inspection tool to measure the surface spacing and chamfer size of the square rod. When the current surface and chamfer measurement of the square rod is completed, the first rotating assembly 22 and the second rotating assembly 32 can be controlled to rotate at the same time to turn the square rod 90 degrees and then continue to inspect the square rod. By analogy, the square rod is turned over multiple times by the rotating assembly to ensure that the four faces and four chamfers of the square rod are inspected. The square bar auxiliary detection device of the present invention can clamp the square bar and flip it 360 degrees through the cooperation of the clamping component, the lifting component and the rotating component, so as to facilitate the detection of the dimensions of each surface and each corner of the square bar, thereby effectively assisting the detection personnel in the detection without the need to move the square bar laboriously. On the one hand, it can effectively shorten the single detection time of the square bar and improve the detection efficiency; on the other hand, it can avoid the damage caused by collision to the square bar during the flipping process of the square bar.

[0027] Further, please also see Figures 2 to 5 The first clamping assembly 21 includes a clamping jaw 211, a screw rod 212, a clamping tool 213, and a hand wheel 214; the clamping tool 213 includes a connecting portion 2131, a first mounting portion 2132 and a second mounting portion 2133, the connecting portion 2131 is connected to the first mounting portion 2132, the first mounting portion 2132 is perpendicular to the second mounting portion 2133, a channel for the clamping jaw 211 to move is provided in the middle of the second mounting portion 2133, and the downwardly extending portions on both sides of the second mounting portion 2133 are provided with a first through hole and a second through hole; one end of the screw rod 212 passes through the first through hole to be connected to the hand wheel 214, and the other end of the screw rod 212 is fixed through the second through hole, and the clamping jaw 211 is slidably installed on the screw rod 212, so that by manually rotating the hand wheel 214, the screw rod 212 is controlled to rotate to drive the clamping jaw 211 to slide, thereby clamping or loosening the other rod. When clamping the square bar, first place the square bar on the second mounting portion, and manually rotate the hand wheel 214 so that the screw rod 212 rotates and drives the clamping jaw 211 to approach the square bar. When the hand wheel 214 cannot rotate, it indicates that the square bar has been clamped, and the hand wheel 214 stops rotating. After the square bar is detected, the square bar can be lowered onto the workbench, and then the hand wheel 214 is rotated in the opposite direction so that the screw rod 212 rotates and drives the clamping jaw 211 away from the square bar, thereby loosening the square bar.

[0028] In some embodiments, one of the two clamping jaws is fixed, and the other is slidably mounted on the screw rod. When the square rod needs to be clamped, one side of the square rod is brought close to the fixed clamping jaw, and then the hand wheel 214 is turned to make the movable clamping jaw follow the screw rod to approach the square rod and clamp it. In some embodiments, both clamping jaws are movable, and the screw rod 212 adopts a bidirectional screw rod, and the thread of the screw rod threaded part is half left-handed and half right-handed. One clamping jaw is set on the left-handed thread, and the other clamping jaw is set on the right-handed thread, so that when the hand wheel rotates to drive the bidirectional screw rod to rotate, the two clamping jaws are close to or away from each other.

[0029] In some embodiments, the clamping portion of the clamping jaw is designed to be rectangular, thereby increasing the contact area with the square rod, making the square rod more firmly clamped and preventing the square rod from falling off during the flipping process. The clamping surface of the clamping jaw is made of rubber non-slip material, which has a stronger clamping force while preventing damage to the square rod caused by excessive clamping force.

[0030] For further information, see Figure 3 The first clamping assembly 21 also includes a vacuum suction cup 215, which is mounted on the first mounting portion 2132 to fix the end face of the square rod by suction, wherein the suction force direction of the vacuum suction cup is perpendicular to the moving direction of the clamping claw. When the square rod is clamped by the first clamping assembly, the clamping claw on the screw rod is moved toward the square rod by rotating the hand wheel to clamp the square rod, and the end face of the square rod is sucked by the vacuum suction cup, thereby strengthening the clamping force on the square rod to prevent the square rod from falling off during the flipping process.

[0031] Furthermore, the structure of the second clamping assembly 31 is the same as that of the first clamping assembly 21. When the right end of the square rod is clamped, the square rod is also placed on the second mounting portion, and the hand wheel 214 is manually rotated so that the screw rod 212 rotates to drive the clamping claw 211 to approach the square rod, and the end surface of the square rod is adsorbed by the vacuum suction cup. When the hand wheel 214 cannot be rotated, it indicates that the square rod has been clamped, so the hand wheel is stopped from rotating. After the square rod is inspected, the square rod can be lowered to the workbench, and then the hand wheel 214 is rotated in the opposite direction so that the screw rod 212 rotates to drive the clamping claw 211 away from the square rod, thereby loosening the square rod.

[0032] Further, please also see Figure 3 and Figure 4, the first rotating assembly 22 includes a rotating motor 221 and a motor mounting frame 222; the rotating motor 221 is mounted on the motor mounting frame 222, and the output shaft of the rotating motor 221 passes through one end of the motor mounting frame 222 and is connected to the connecting portion 2131 of the clamping fixture, so as to control the rotation of the first clamping assembly 21 through the rotating motor 221, thereby driving the square rod to rotate; the structure of the second rotating assembly 32 is the same as that of the first rotating assembly 22. Among them, the connecting portion of the clamping fixture is provided with a through hole, and the output shaft of the rotating motor 221 passes through one end of the motor mounting frame 222 and then passes through the through hole of the connecting portion 2131 and is installed with the connecting plate, so as to ensure that the first clamping assembly can rotate stably when the rotating motor rotates. When controlling the square rod to flip, the rotating motor 221 is controlled to rotate forward and reverse to achieve different flipping directions of the square rod, and the rotating motor of the first rotating assembly 22 and the rotating motor of the second rotating assembly 32 are arranged relative to each other, so when the first rotating assembly and the second rotating assembly are controlled to rotate at the same time, the directions of the two rotating motors are opposite.

[0033] Further, please also see Figures 3 to 5 The first lifting assembly 23 includes a lifting screw 231, a lifting slider 232, and a lifting motor 233; the other end of the motor mounting frame 22 is connected to the lifting slider 232, and the lifting slider 232 is slidably set on the lifting screw 231. The lifting motor 233 is connected to the lifting screw 231 to drive the lifting screw 231 to rotate, drive the lifting slider 232 to move up and down, and drive the first rotating assembly 22 to move up and down. The second lifting assembly 33 has the same structure as the first lifting assembly 23. After the two ends of the square rod are clamped by the first clamping assembly 21 and the second clamping assembly 31, the lifting screw 231 can be driven to rotate by the lifting motor 233, and the lifting slider 232 moves upward following the rotation of the lifting screw 231, thereby driving the first rotating assembly, the first clamping assembly, the second rotating assembly, the second clamping assembly and the square rod to move upward.

[0034] In some embodiments, the first lifting assembly 23 is provided with a front plate 235 and a housing 236 outside the lifting screw 231 to protect the lifting screw, reduce the entry of dust, and improve the service life of the lifting screw. The housing 236 includes an upper plate, a lower plate, a side plate, and a rear plate, each of which is connected by screws. The installation position of the front plate 235 corresponds to the rear plate position of the housing 236. During installation, the lifting slider 232 is first installed with the lifting screw 231, and then the front plate 235 and the housing 236 are installed by screws. Finally, the motor mounting frame 222 and the lifting slider 232 are installed by bolts. After the motor mounting frame 222 and the lifting slider 232 are installed, a cavity is formed for the front plate 235 to pass through, so that the lifting screw can be protected without affecting the lifting slider 232 to drive the motor mounting frame 222 to lift. Meanwhile, the first lifting assembly 23 is provided with a base 234 at the bottom of the shell, and the lifting screw rod 231 and the lifting motor 233 are arranged side by side on the base 234, and the lifting screw rod 231 and the lifting motor 233 are connected by two gear meshing. In some embodiments, the base 234 is connected to the bottom of the first mounting frame by bolts, and the rear plate of the shell 236 is connected to the vertical part of the first mounting frame by bolts, so as to ensure the stability of the first clamping mechanism when the first moving mechanism drives the first clamping mechanism to move through the first mounting frame.

[0035] Further, please also see Figure 2 , Figure 5 and Figure 6 The first moving mechanism 40 includes a moving motor 41, a moving screw rod 42, a guide rail 43, a moving slider 44, and a connecting piece 45; the moving motor 41 is connected to the moving screw rod 42, and guide rails 43 are respectively arranged on both sides of the moving screw rod 42, and the track direction of the guide rail 43 is consistent with the screw direction of the moving screw rod 42; the moving slider 44 is slidably arranged on the guide rail 43, the moving slider 44 is connected to the moving screw rod 42, and the moving slider 44 is connected to the first mounting frame 60 through the connecting piece 45. When the first clamping assembly 20 needs to move, the moving motor 41 drives the moving screw rod 42 to rotate, and the moving slider 44 is connected to the moving screw rod 42, so that when the moving screw rod 42 rotates, the moving slider 44 follows the moving screw rod 42 to move along the track of the guide rail 43, and the moving slider 44 is connected to the first mounting frame 60 through the connecting piece 45, so that when the moving slider 44 moves, it can drive the first mounting frame 60 to move, thereby driving the first clamping assembly 20 to move.

[0036] In some embodiments, in order to protect the moving screw rod, an upper plate 46 and a side plate 47 may be arranged around the moving screw rod to surround the moving screw rod. The moving screw rod 42 is surrounded by the side plate 47, and then the connecting member 45 is connected to the moving slide 44, and then the upper plate 46 is installed above the moving screw rod 42, and connected to the side plate 47 by bolts, and finally the first mounting frame 60 is connected to the connecting member 45 by bolts, and after the first mounting frame 60 and the connecting member 45 are installed, a cavity is formed for the upper plate 46 to pass through, so that the moving screw rod can be protected while the first mounting frame 60 can be driven to move without affecting the connecting member 45.

[0037] In some embodiments, the structure of the second moving mechanism 50 is the same as that of the first moving mechanism 40, and the control principle is also the same as that of the first moving mechanism 40. Please refer to the above structural description and control process description, which will not be repeated here.

[0038] Further, please also see Figure 7 and Figure 8 , and also includes a measuring mechanism 80, which includes a measuring assembly 81, a toothed belt 82, a driving motor 83, a first frame 84 and a second frame 85; the first frame 84 and the second frame 85 are symmetrically arranged on both sides of the workbench, and the first frame 84 corresponds to the position of the first clamping mechanism 20, and the second frame 85 corresponds to the position of the second clamping mechanism 30; a belt driving wheel 86 is arranged at the first frame 84, and the belt driving wheel 86 is connected to the driving motor 83, and a driven wheel 87 is arranged at the second frame 85, and the toothed belt 82 passes through the first frame 84 and meshes with the belt driving wheel 86, and passes through the second frame 85 and meshes with the driven wheel 87 to form a closed loop; the measuring assembly 81 is installed on the toothed belt 82 through a fixing member. The measuring mechanism 80 is mainly used to measure the surface spacing of the square rod. When measuring the surface spacing, it is necessary to select multiple points on a surface to measure the surface spacing, so as to obtain accurate surface spacing data, so the measuring mechanism 80 can be moved on the workbench.

[0039] Specifically, the bottom of the measuring assembly 81 and the fixing member are fixed to the toothed belt 82 by bolts. When the measuring assembly 81 needs to be moved, the belt driving wheel 86 is driven by the driving motor 83 to rotate, driving the toothed belt 82 to move, and the measuring assembly 81 fixed on the toothed belt 82 moves along with the toothed belt. Through the meshing of the toothed belt and the gear, the transmission efficiency can be improved, high-precision rotation can be achieved, and the transmission stability is better, so that the moving position of the measuring assembly 81 can be accurately controlled.

[0040] Further, please also see Figure 2 and Figure 8The measuring component 81 includes a display screen 811 and a measuring probe 812. After the measuring component 81 is moved to a position relative to the square rod, the inter-plane distance on the surface of the square rod is measured by the measuring probe 812, wherein the height of the square rod is adjusted according to the height set by the measuring probe 812, so as to ensure that the surface of the square rod can be detected by the measuring probe, and the measured inter-plane distance data is displayed on the display screen 811.

[0041] In some embodiments, the display screen 811 is a touch screen, and a controller is installed in the measuring component 81. The moving motor, lifting motor, rotating motor and driving motor are all electrically connected to the controller. The inspector can control the corresponding motor to work by performing touch operations on the touch screen.

[0042] In some embodiments, a controller can be set on the workbench, and the moving motor, lifting motor, rotating motor and driving motor are all electrically connected to the controller, and the controller is electrically connected to the operating handle. The inspection personnel can control the corresponding motor to work by operating the operating handle, so that the various mechanisms of the square rod auxiliary detection device can perform corresponding actions.

[0043] Furthermore, the measuring mechanism 80 further includes a polished rod 88, one end of which is fixed to the first frame 84, and the other end of which is fixed to the second frame 85. The measuring assembly 81 is sleeved on the polished rod 88 and moves along the polished rod 88. When the measuring assembly 81 moves following the toothed belt 82, it also moves along the polished rod 88 to improve the stability of the measuring assembly when it moves. In some embodiments, two polished rods 88 are provided.

[0044] In some embodiments, there are two measuring mechanisms, which are respectively arranged on both sides of the moving mechanism and the clamping mechanism, so that the surface spacing between the two surfaces of the square rod can be detected simultaneously, thereby improving the detection efficiency and accuracy of the square rod.

[0045] The present invention also provides a square bar auxiliary detection method, which uses the square bar auxiliary detection device as described above and comprises the following steps: S1. According to the length of the square rod, control the first moving mechanism and the second moving mechanism to drive the first clamping mechanism and the second clamping mechanism to move to a suitable position; S2, placing the square rod on the first clamping assembly and the second clamping assembly, and clamping the left end of the square rod by the first clamping assembly, and clamping the right end of the square rod by the second clamping assembly; S3, controlling the first lifting assembly and the second lifting assembly to drive the square rod to rise; S4. When the square rod rises to the set height, the other rod is inspected. When inspecting the other rod, the inspector can measure the face distance of the other rod through the measuring mechanism, and then use an angle ruler to detect the verticality of each face, and use a caliper to detect the size of the chamfer.

[0046] S5, after the detection is completed, control the first rotating assembly and the second rotating assembly to rotate the square rod 90 degrees, and then detect the square rod; S6. After each surface of the square bar has been inspected, the first lifting assembly and the second lifting assembly are controlled to drive the square bar down, and the first clamping assembly and the second clamping assembly are controlled to release to remove the square bar.

[0047] In actual use, first, according to the length of the square rod, the moving motor 41 of the first moving mechanism is controlled to work to drive the moving screw 42 to rotate, and the moving slider 44 follows the moving screw 42 to move along the track of the guide rail 43, driving the first mounting frame 60 to move, thereby driving the first clamping mechanism 20 to move; at the same time, the second moving mechanism is controlled to drive the second clamping mechanism 30 to move. When the first clamping mechanism 20 and the second clamping mechanism 30 are moved to a suitable position, the left end of the square rod is placed on the second mounting portion 2133 of the clamping fixture of the first clamping assembly 21, and the hand wheel 214 is manually rotated so that the screw 212 rotates to drive the clamping claw 211 to approach the square rod, and the end face of the square rod is adsorbed by the vacuum suction cup 215. When the hand wheel 214 cannot be rotated, it indicates that the left end of the square rod has been clamped, so the hand wheel is stopped; at the same time, the right end of the square rod is placed on the second mounting portion 2133 of the clamping fixture of the second clamping assembly 31, and the right end of the square rod is clamped in the same way. Next, the first lifting assembly 23 and the second lifting assembly 33 are operated simultaneously, and the lifting motor 233 is controlled to drive the lifting screw 231 to rotate, so that the lifting slider 232 moves upward, thereby driving the square rod to rise. After rising to the set height, the driving motor 83 is controlled to drive the belt drive wheel 86 to drive the toothed belt 82 to run, thereby driving the measuring assembly to the corresponding position, and using the measuring probe 812 to detect the surface spacing of the surface of the square rod. After the surface spacing measurement is completed, the inspection personnel use an angle ruler to detect the verticality of each surface and a caliper to detect the size of the chamfer.

[0048] When the surface spacing, verticality and chamfer measurements of the current surface are completed, the rotary motor 221 of the first rotary assembly 22 and the rotary motor of the second rotary assembly 32 can be controlled to rotate forward and reverse at the same time, so that the square rod can be flipped 90° counterclockwise, and the square rod can be measured again by the measuring assembly, angle ruler and caliper. After multiple flips, it is ensured that each surface and each chamfer of the square rod are detected. After the square rod is detected, the lifting motors of the first lifting assembly 23 and the second lifting assembly 33 are started at the same time to control the descent of the square rod. When it descends to the workbench, the first clamping assembly 21 and the second clamping assembly 31 rotate the handwheel in the opposite direction so that the screw rod rotates to drive the clamping claw away from the square rod, thereby loosening the square rod and removing the square rod.
