Description

Technical Field

[0001] The invention belongs to the technical field of mechanical engineering, and in particular relates to an intelligent control calibration device for a torque limiter. Background Art

[0002] The torque limiter, also known as a safety clutch or safety coupling, is often installed between the active and passive sides of the power transmission (i.e., between the input shaft and the output shaft). When an overload fault occurs (the torque exceeds the set value), the torque limiter will separate, thereby effectively protecting the driving machinery (such as motors, reducers, servo motors) and the loaded products.

[0003] At present, the torque limiter usually assembles the first gear (large gear), the second gear (small gear), a flat washer, a spring washer and a nut together, and the subsequent torque measurement and marking are all achieved by manual operation, that is, a torque wrench is usually used to manually tighten the nut and measure the torque, and the torque data is recorded after the torque measurement is qualified, and then the data is input into the marking machine for manual marking. The manual detection and marking of the torque limiter is not only labor-intensive and inefficient, but also seriously affects the reliability and stability of the equipment operation. Summary of the invention

[0004] In view of this, the purpose of the present invention is to provide an intelligent control and calibration device for a torque limiter, aiming to solve the technical problems of high labor intensity and poor stability caused by manual operation in the current torque limiter detection and marking.

[0005] To achieve the above object, the present invention provides the following technical solution: an intelligent control calibration device for a torque limiter, comprising:

[0006] a workbench, wherein the workbench is slidably provided with a torque limiter;

[0007] A meshing gear assembly, disposed on the workbench, for meshing with the first gear of the torque limiter to drive the first gear to rotate;

[0008] A nut screwing assembly, disposed on the workbench, for screwing the nut of the torque limiter to adjust the torque value of the torque limiter;

[0009] a marking machine, arranged on the workbench, for marking the torque limiter, and;

[0010] The controller is arranged on the workbench and is used for receiving the meshing information between the meshing gear assembly and the first gear to control the operation of the nut screwing assembly, and for receiving the torque value of the torque limiter obtained by the nut screwing assembly to control the operation of the marking machine.

[0011] Furthermore, the meshing gear assembly includes a meshing support seat, a bearing seat installed on the meshing support seat, a rotating shaft rotatably installed on the bearing seat, a driving gear arranged at one end of the rotating shaft and used to mesh with the first gear, and a rotating cylinder installed at the other end of the rotating shaft.

[0012] Furthermore, the rotary cylinder is arranged on a side of the workbench facing away from the bearing seat, and a through hole is provided on the workbench for the rotary shaft to pass through and connect with the rotary cylinder.

[0013] Furthermore, a displacement sensor for real-time monitoring of the meshing of the driving gear and the first gear is disposed on the rotating shaft.

[0014] Furthermore, the nut screwing assembly includes a support frame, a screwing cylinder liftably mounted on the support frame, and a nut sleeve arranged at one end of the screwing cylinder and sleeved with the nut.

[0015] Furthermore, the nut and the nut sleeve are connected by magnetic attraction.

[0016] Furthermore, the nut screwing assembly also includes a lifting plate arranged on the support frame, and a lifting cylinder for driving the lifting plate to rise and fall, and the screwing cylinder is arranged on the lifting plate.

[0017] Furthermore, it also includes a slide table arranged on the workbench, a slide plate slidably mounted on the slide table, a mounting plate slidably arranged on the slide plate and used to carry the torque limiter, and a pushing motor arranged on the workbench and used to push the slide plate to slide.

[0020] The beneficial effect of the present invention is that compared with the prior art, the intelligent control and calibration device of the torque limiter in the present invention can mesh the first gear of the torque limiter and drive the first gear to rotate through the meshing gear assembly. When the controller obtains the meshing information between the meshing gear assembly and the first gear, the nut screwing assembly can be controlled to screw the nut of the torque limiter. When the torque value of the torque limiter reaches the preset value, the nut screwing assembly will feed back the acquired torque value information to the controller, and the controller then controls the marking machine to perform marking. The torque detection and marking of the torque limiter are automatically realized by the present device, which greatly reduces the labor intensity, improves the production efficiency, and enhances the reliability and stability of the equipment operation.

[0038] like Figures 1 to 5 As shown, this embodiment proposes an intelligent control calibration device for a torque limiter, which includes a workbench 1, a meshing gear assembly 2, a nut screwing assembly 3, a marking machine 4, and a controller (not shown in the drawings). The workbench 1 is provided with a torque limiter 11, and the torque limiter 11 can slide along the workbench 1. The meshing gear assembly 2, the nut screwing assembly 3, the marking machine 4, and the controller are all arranged on the workbench 1. Specifically, the meshing gear assembly 2 is meshed with the first gear 12 of the torque limiter 11 to drive the first gear 12 to rotate. The nut screwing assembly 3 can be used to screw the nut of the torque limiter 11 to adjust the torque value of the torque limiter 11, and the marking machine 4 can be used to mark the torque limiter 11. The controller is electrically connected to the meshing gear assembly 2, the nut screwing assembly 3, and the marking machine 4 respectively. The controller can be used to receive the meshing information between the meshing gear assembly 2 and the first gear 12 to control the operation of the nut screwing assembly 3. At the same time, the controller is also used to receive the torque value of the torque limiter 11 obtained by the nut screwing assembly 3 to control the operation of the marking machine 4. In this way, through the meshing gear assembly 2, the first gear 12 of the torque limiter 11 can be meshed and drive the first gear 12 to rotate. When the controller obtains the meshing information between the meshing gear assembly 2 and the first gear 12, the nut screwing assembly 3 can be controlled to screw the nut of the torque limiter 11. When the torque value of the torque limiter 11 reaches a preset value, the nut screwing assembly 3 will feed back the obtained torque value information to the controller, and the controller further controls the marking machine 4 to perform marking. The device automatically realizes the detection and marking of the torque of the torque limiter 11, greatly reduces the manual labor intensity, improves the production efficiency, and enhances the reliability and stability of the equipment operation.

[0039] Preferably, in this embodiment, the preset value range of the torque value is 28-38 N.m. Specifically, the preset value can be 28 N.m, 30 N.m, 32 N.m, 34 N.m, 36 N.m, 38 N.m, etc. Of course, according to actual conditions and specific needs, the preset value of the torque value can also be set to other ranges, which is not limited here.

[0040] In the present application, through the sliding torque limiter 11, when the torque limiter 11 slides to engage with the meshing gear assembly 2, the controller controls the nut screwing assembly 3 to screw the nut of the torque limiter 11, and monitors the torque value of the torque limiter 11 in real time. When the torque value of the torque limiter 11 reaches a preset value, the controller controls the nut screwing assembly 3 to stop working, and at the same time controls the marking machine 4 to mark the torque limiter 11, thereby realizing the automated processing of torque detection and marking, and greatly improving production efficiency.

[0041] Preferably, see Figure 4 As shown, the workbench 1 is also provided with a control panel 13, and the controller is arranged on the control panel 13. In this way, manual operation can be facilitated to improve working efficiency.

[0042] For further information, see Figure 4 As shown, the meshing gear assembly 2 includes a meshing support seat 21, the meshing support seat 21 is provided with a bearing seat 22, a rotating shaft 23 is rotatably mounted on the bearing seat 22, and in addition, a driving gear 24 is provided at one end of the rotating shaft 23, the driving gear 24 is meshed with the first gear 12, and a rotating cylinder 25 is provided at the other end of the rotating shaft 23. In this way, the rotating shaft 23 is controlled to rotate by the rotating cylinder 25, the rotating shaft 23 drives the driving gear 24 to rotate, and the driving gear 24 further drives the first gear 12 to rotate, so as to realize power transmission.

[0043] Preferably, see Figure 4 As shown, the rotary cylinder 32 is arranged on the side of the workbench 1 facing away from the bearing seat 22, and a through hole is opened on the workbench 1, through which the rotary shaft 23 can pass and connect with the rotary cylinder 32. Through such a distribution, the space of the workbench 1 is fully utilized, the structure is relatively compact, and the occupied area of ​​the structure is reduced.

[0044] For further information, see Figure 1 and Figure 4 As shown, a displacement sensor (not shown in the drawings) is disposed on the rotating shaft 23. The displacement sensor can be used to monitor the meshing condition of the driving gear 24 and the first gear 12 in real time and transmit the meshing information to the controller.

[0045] In the present application, through the sliding torque limiter 11, when the torque limiter 11 slides to engage with the driving gear 24, at this time, when the displacement sensor detects that the driving gear 24 is engaged with the first gear 12 of the torque limiter 11, the monitored engagement information is transmitted to the controller, and the controller controls the nut screwing assembly 3 to screw the nut of the torque limiter 11, and monitors the torque value of the torque limiter 11 in real time. When the torque value of the torque limiter 11 reaches a preset value, the controller controls the nut screwing assembly 3 to stop working, and at the same time controls the marking machine 4 to mark the torque limiter 11, thereby realizing the automated processing of torque detection and marking.

[0046] For further information, see Figure 2 As shown, the nut screwing assembly 3 includes a support frame 31, a screwing cylinder 32, and a nut sleeve 33. The screwing cylinder 32 can be installed on the support frame 31 in a liftable manner. The nut sleeve 33 is arranged at one end of the screwing cylinder 32, and the nut sleeve 33 can be connected with the nut sleeve. In this way, when the screwing cylinder 32 is lifted to a suitable position, the screwing cylinder 32 drives the nut sleeve 33 to rotate, and the nut sleeve 33 then screws the nut to adjust the torque value of the torque limiter 11. When the torque value of the torque limiter 11 reaches a preset value, the controller controls the nut screwing assembly 3 to stop working, so as to monitor and adjust the torque value of the torque limiter 11.

[0047] Preferably, the nut is connected to the nut sleeve 33 by magnetic attraction. Specifically, the nut is adsorbed on the nut sleeve 33 by a rubidium magnet. The magnetic attraction method is simple and convenient on the one hand, and can achieve accurate and efficient connection on the other hand.

[0048] For further information, see Figure 2 As shown, the nut screwing assembly 3 further includes a lifting plate 34, which is disposed on the support frame 31, and the screwing cylinder 32 is disposed on the lifting plate 34. In this way, the lifting plate 34 can be driven to rise and fall by the lifting cylinder 35, and the lifting plate 34 can further drive the screwing cylinder 32 to rise and fall, thereby realizing the adjustment of the height of the screwing cylinder 32.

[0049] In the present application, the lifting cylinder 35 is electrically connected to the controller, so that when the screwing cylinder 32 is lifted to a suitable position, the screwing cylinder 32 drives the nut sleeve 33 to rotate, and the nut sleeve 33 then screws the nut to adjust the torque value of the torque limiter 11. When the torque value of the torque limiter 11 reaches a preset value, the controller controls the nut screwing assembly 3 to stop working, and the controller controls the lifting cylinder 35 to drive the screwing cylinder 32 to return to the initial position to avoid interference with the marking machine 4 during marking.

[0050] Preferably, in the present application, the screwing cylinder 32 has a detection function, that is, when the screwing cylinder 32 drives the nut sleeve 33 to screw the nut, the torque value of the torque limiter 11 can be detected in real time. When the torque value reaches a preset value, the detection information is transmitted to the controller, and the controller controls the marking machine 4 to perform marking processing.

[0051] For further information, see Figure 1 As shown, the workbench 1 is also provided with a slide 5, the slide 5 is provided with a slide plate 6, the slide plate 6 is provided with a mounting plate 7, the mounting plate 7 can be used to carry the torque limiter 11, and in addition, the workbench 1 is also provided with a driving motor 8, the driving motor 8 can be used to drive the slide plate 6 to slide. In this way, the slide plate 6 is driven by the driving motor 8 to move along the slide 5, the slide plate 6 drives the mounting plate 7 to move, and the mounting plate 7 drives the torque limiter 11 to move, thereby realizing the adjustment of the position of the torque limiter 11.

[0052] In the present application, the mounting plate 7 can be driven to move by the slide plate 6, thereby achieving a coarse adjustment of the position of the torque limiter 11. Subsequently, the position of the torque limiter 11 can be finely adjusted by sliding the mounting plate 7, thereby effectively ensuring that the first gear 12 is meshed with the driving gear 24.

[0053] Preferably, see Figure 1 As shown, the slide 5 is provided with a guide rail 51, a slider 52 is provided on the guide rail 51, and the slide plate 6 is arranged on the slider 52. In this way, the slide plate 6 can be guided to slide along the extending direction of the guide rail 51 by cooperating with the slider 52.

[0054] For further information, see Figure 1 As shown, the slide plate 6 is also provided with a push-up assembly 9, which can be used to elastically push the mounting plate 7. By providing the push-up assembly 9, the mounting plate 7 can be pushed up, thereby ensuring that the first gear 12 of the torque limiter 11 arranged on the mounting plate 7 is well meshed with the driving gear 24.

[0055] Preferably, see Figure 1 As shown, the push-up assembly 9 includes a connecting seat 91, a mounting seat 92, a pin 93, and a spring 94. The connecting seat 91 is fixedly connected to the mounting plate 7, the mounting seat 92 is fixedly connected to the slide plate 6, the pin 93 can be used to connect the mounting seat 92 with the connecting seat 91, and the spring 94 is sleeved on the pin 93 and can elastically push up the connecting seat 91. In this way, the spring 94 continuously pushes up the connecting seat 91, and the connecting seat 91 further pushes up the first gear 12 to continuously mesh with the driving gear 24.
