In addition, the description of "first", "second" and the like in the present application is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one of the features. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the fact that those skilled in the art can realize it, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the protection scope required by the present application.

[0046] In the related art, there is a technical problem of high labor intensity when polishing the strip steel. The embodiments of the present application provide a strip steel polishing mechanism and a strip steel polishing system, which can at least solve the technical problem of high labor intensity when polishing the strip steel to a certain extent.

[0047] The present application will be described below in conjunction with the drawings and specific embodiments:

[0048] As shown in Figures 1 to 7 The strip steel polishing mechanism 100 is used for polishing the strip steel, and includes a support seat 110, a lifting assembly 120, a driving assembly 130 and a polishing assembly 140.

[0049] The support seat 110 is used for fixed connection with a support mechanism 200 capable of enabling the strip steel polishing mechanism 100 to be located above the strip steel and driving the strip steel polishing mechanism 100 to walk on the surface of the strip steel.

[0050] The support mechanism 200 can be a support frame arranged above the strip steel. Of course, the support mechanism 200 can also be a movable support mechanism 200 such as a mechanical arm. When the strip steel polishing mechanism 100 is not used, the movable support mechanism 200 such as the mechanical arm is retracted and does not occupy the area above the strip steel. When the strip steel polishing mechanism 100 is to be used, the movable support mechanism 200 such as the mechanical arm moves to above the strip steel, so that the strip steel polishing mechanism 100 mounted thereon is located above the strip steel and the oil stone 300 is in contact with the surface of the strip steel. It should be noted that when the support mechanism 200 is located above the strip steel, the support structure can drive the strip steel polishing mechanism 100 to slide along the length direction, the width direction or the like of the strip steel, so that the oil stone 300 on the strip steel polishing mechanism 100 can polish the surface of the strip steel.

[0051] The lifting assembly 120 is mounted to the support base 110, the driving and rotating assembly 130 is mounted to the lifting assembly 120, and the lifting assembly 120 is used to drive the driving and rotating assembly 130 to lift. The polishing assembly 140 is used to fix the oil stone 300, and the polishing assembly 140 is mounted to the driving and rotating assembly 130, and the driving and rotating assembly 130 is used to drive the polishing assembly 140 to rotate.

[0052] The lifting assembly 120 drives the driving and rotating assembly 130 to lift, and the polishing assembly 140 is mounted on the driving and rotating assembly 130. Therefore, the polishing assembly 140 can lift under the action of the lifting assembly 120, and the polishing assembly 140 can also rotate under the action of the driving and rotating assembly 130. The polishing assembly 140 is used to fix the oil stone 300, so that the oil stone 300 on the polishing assembly 140 can lift under the action of the lifting assembly 120 and rotate under the action of the driving and rotating assembly 130.

[0053] In this way, when the surface of the strip steel needs to be polished, the lifting assembly 120 can be controlled to act so that the oil stone 300 is in contact with the surface of the strip steel, and the strip steel polishing mechanism 100 can walk on the surface of the strip steel under the action of the support mechanism 200, so that the surface of the strip steel can be polished, the labor intensity is reduced, and the polishing efficiency of the strip steel is improved. When the surface of the strip steel is polished, the driving and rotating assembly 130 can be controlled to act so that the polishing angle of the oil stone 300 can be adjusted, which helps to increase the area of the strip steel polished by the oil stone 300 when the oil stone 300 moves, improve the polishing efficiency, and also avoid scratching the surface of the strip steel by the edges and corners of the oil stone 300 when the oil stone 300 polishes the strip steel.

[0054] The polishing assembly 140 can fix the oil stone 300 by clamping, bonding, bolt connection or the like, which is not limited in the present application. The lifting assembly 120 can include components such as hydraulic cylinders, air cylinders or linear motors, and the driving and rotating assembly 130 can include components such as motors and transmission gears, which are not limited in the present application.

[0055] In some embodiments, the polishing assembly 140 comprises a rotating disc 141, an oil stone chuck 142, a flexible spring 143, a support 144 and a connecting member (not shown in the figure). The rotating disc 141 is connected to the output end of the driving assembly 130; the oil stone chuck 142 is used to fix the oil stone 300; the flexible spring 143 is elastic and fixedly connected to the rotating disc 141 along the radial direction of the rotating disc 141, at least part of the flexible spring 143 extends out of the rotating disc 141; the support 144 is arranged between the oil stone chuck 142 and the part of the flexible spring 143 extending out of the rotating disc 141, so that the flexible spring 143 is arranged in a spaced manner with the oil stone chuck 142; the connecting member is arranged through the flexible spring 143, the support 144 and the oil stone chuck 142, so as to fixedly connect the flexible spring 143, the support 144 and the oil stone chuck 142.

[0056] The rotating disc 141 is drivingly connected to the output end of the driving assembly 130, the driving assembly 130 drives the rotating disc 141 to rotate, the flexible spring 143 is fixedly connected to the rotating disc 141, and the flexible spring 143 rotates together with the rotating disc 141. Since the connecting member fixedly connects the flexible spring 143, the support 144 and the oil stone chuck 142, the oil stone chuck 142 can rotate together with the rotating disc 141. Since the oil stone 300 is fixed on the oil stone chuck 142, the oil stone 300 can also rotate together with the rotating disc 141, and the polishing angle of the oil stone can be adjusted. The connecting member can be a bolt or a screw, which is not limited in the present application.

[0057] Along the radial direction of the rotating disc 141, at least part of the flexible spring 143 extends out of the rotating disc 141, that is, as shown in Figure 1 and Figure 6 , at least part of the flexible spring 143 does not lie between the rotating disc 141 and the oil stone chuck 142, but extends out of the rotating disc 141. The flexible spring 143 has a certain elasticity and can be deformed under stress. The support 144 is arranged between the oil stone chuck 142 and the part of the flexible spring 143 extending out of the rotating disc 141, so that the flexible spring 143 is arranged in a spaced manner with the oil stone chuck 142. In this way, under the action of the flexible spring 143 and the support 144, the oil stone chuck 142 is flexibly connected to the rotating disc 141, the oil stone chuck 142 can rotate relative to the rotating disc 141, the inclination angle of the oil stone 300 on the oil stone chuck 142 can be changed, the oil stone 300 can be tightly attached to the surface of the strip steel, the stress on the surface of the strip steel tends to be uniform, which helps to avoid the edges and corners of the oil stone 300 scratching the surface of the strip steel during polishing, and ensures the polishing quality. The material of the flexible spring 143 is various, which can be plastic or metal material, etc.

[0058] As shown in Figure 6As shown, in some embodiments, the flexible elastic piece 143 includes a connecting portion 1431 and a plurality of ear portions 1432 arranged outside the connecting portion 1431; the connecting portion 1431 is located between the rotating disc 141 and the oil stone chuck 142 and fixedly connected with the rotating disc 141; along the radial direction of the rotating disc 141, the ear portions 1432 protrude from the rotating disc 141, the support 144 is arranged between the ear portions 1432 and the oil stone chuck 142, and the connecting member is arranged through the ear portions 1432, the support 144 and the oil stone chuck 142.

[0059] The number of the support 144 and the connecting member is consistent with the number of the ear portions 1432, and the number of the ear portions 1432 can be two, three, four, etc., which is not limited in the present application. The connecting portion 1431 is fixedly connected with the ear portions 1432, and the connecting portion 1431 is used for fixedly connecting with the rotating disc 141. The connecting portion 1431 and the rotating disc 141 can be fixedly connected by means of bolt connection, adhesion, etc.

[0060] In some embodiments, the driving assembly 130 includes a driving member 131, a speed reducer 132, a fixed disc 134 and a damping assembly 133. The output shaft of the driving member 131 is drivingly connected to the speed reduction assembly of the speed reducer 132, and the speed reduction assembly of the speed reducer 132 is further connected with the polishing assembly 140; the fixed disc 134 is fixedly connected to the housing of the speed reducer 132; the damping assembly 133 is located between the fixed disc 134 and the lifting assembly 120 and connected to the fixed disc 134 and the lifting assembly 120.

[0061] The driving member 131 can be a synchronous motor, and the speed reducer 132 can be a planetary reducer. The structures of the synchronous motor and the planetary reducer are various, and are known to those skilled in the art, which are not limited in the present application. In some embodiments, the driving member 131 is a synchronous motor with self-locking function. When stopping, the motor is self-locked, and the output shaft cannot rotate, so that the oil stone 300 maintains the polishing angle at the time when the motor stops. The speed reducer 132 plays a role of speed reduction and torque increase, and can convert the high-speed low-torque power generated by the synchronous motor into low-speed high-torque power. The speed reducer 132 includes a speed reduction assembly and a housing. The speed reduction assembly can include planetary gears, sun gears, ring gears, etc., and is installed in the housing. The output shaft of the driving member is drivingly connected to the speed reduction assembly of the speed reducer 132, and drives the speed reduction assembly to rotate. The housing of the speed reducer 132 is fixedly connected to the fixed disc 134. The speed reduction assembly is further connected with the polishing assembly 140, and drives the polishing assembly 140 to rotate. In the embodiment in which the polishing assembly 140 includes the rotating disc 141, the oil stone chuck 142, the flexible elastic piece 143, the support 144 and the connecting member, the speed reduction assembly is connected with the rotating disc 141 of the polishing assembly 140 and drives the rotating disc 141 to rotate.

[0062] When the strip grinding mechanism 100 travels along the strip surface under the action of the support mechanism 200, the grinding component 140 is prone to vibration in the lifting direction of the lifting component 120 due to friction, resulting in vibration marks on the strip surface and affecting the grinding quality. These embodiments, through the installation of the vibration damping component 133, dampen the grinding component 140 in the lifting direction of the lifting component 120, thereby reducing the amplitude of vibration and minimizing vibration marks, ultimately improving the grinding quality of the strip.

[0063] In some embodiments, the lifting assembly 120 includes an electric lead screw 121 and a lifting arm 122. The electric lead screw 121 is mounted on a support base 110; the lifting arm 122 is mounted on the electric lead screw 121 and is slidably connected to the support base 110 along the lifting direction of the electric lead screw 121; and the shock absorption assembly 133 is connected to the fixed plate 134 and the lifting arm 122.

[0064] The structure of the electric lead screw 121 is known to those skilled in the art, including components such as a motor, lead screw, and nut, and will not be described in detail in this application. The electric lead screw 121 is mounted on the support base 110 and connected to the lifting arm 122, driving the lifting arm 122 to rise or fall. The lifting arm 122 and the support base 110 are slidably connected along the lifting direction of the electric lead screw 121, which helps to improve the stability of the lifting arm 122 during the lifting process. In these embodiments, the shock-absorbing component 133 and the fixed plate 134 are spaced apart along the lifting direction of the electric lead screw 121, with the shock-absorbing component 133 located between the fixed plate 134 and the lifting arm 122, connecting the fixed plate 134 and the lifting arm 122.

[0065] like Figure 4 As shown, in some embodiments, the shock absorption assembly 133 includes a guide member 1331, an elastic member 1332, and two limiting members 1333. The guide member 1331 is slidably connected to the lifting arm 122 and the fixed plate 134 along the lifting direction of the electric screw 121, and passes through the lifting arm 122 and the fixed plate 134. The two limiting members 1333 are installed on both sides of the guide member 1331, and the lifting arm 122 and the fixed plate 134 are located between the two limiting members 1333. The elastic member 1332 is sleeved on the outside of the guide member 1331 and is located between the lifting arm 122 and the fixed plate 134, with its two ends abutting against the fixed plate 134 and the lifting arm 122, respectively.

[0066] Two ends of the guide piece 1331 are respectively penetrated through the lifting arm 122 and the fixed disc 134, the limiting pieces 1333 are fixedly connected to the two ends of the guide piece 1331, and the lifting arm 122 and the fixed disc 134 are located between the two limiting pieces 1333, so that the maximum distance between the fixed disc 134 and the lifting arm 122 is limited by the two limiting pieces 1333. The elastic piece 1332 is sleeved outside the guide piece 1331 and located between the lifting arm 122 and the fixed disc 134, and the two ends of the elastic piece 1332 are respectively in abutment with the fixed disc 134 and the lifting arm 122. In this way, when the polishing assembly 140 vibrates and the fixed disc 134 moves towards the lifting arm 122 under the action of vibration, the elastic piece 1332 is compressed and deformed, absorbs and consumes most of the impact force, thereby reducing the vibration amplitude of the polishing assembly 140, and at the same time, the polishing assembly 140 can return to the initial position under the action of the elastic piece 1332.

[0067] In some embodiments, the elastic piece 1332 is a spring, the spring is always in a compressed state, the guide piece 1331 is provided with external threads on both sides in the length direction, and the limiting piece 1333 is provided with a threaded hole, and the limiting piece 1333 is threadedly connected with the guide piece 1331.

[0068] The number of the damping assemblies 133 is not limited in the present application, and in some embodiments, four damping assemblies 133 are provided.

[0069] In some embodiments, the polishing assembly 140 further comprises a rotary bearing 145, the rotary bearing 145 is sleeved on the rotating disc 141 and located between the rotating disc 141 and the driving assembly 130, and connected to the driving assembly 130 and the rotating disc 141.

[0070] The structure of the rotary bearing 145 is known to those skilled in the art, and will not be described here. Specifically, the inner ring of the rotary bearing 145 is sleeved on the rotating disc 141 and fixedly connected with the rotating disc 141, and the outer ring of the rotary bearing 145 is fixedly connected with the fixed disc 134 of the driving assembly 130. By providing the rotary bearing 145, the rotating disc 141 and the fixed disc 134 are connected, which avoids the separation of the rotating disc 141 and the speed reduction assembly of the speed reducer 132, and helps to ensure the stability of the rotation of the rotating disc 141.

[0071] As shown in FIGS. 1, 2 and 3, in some embodiments, the driving assembly 130 is located in the lifting arm 122. Figure 3 and Figure 4 As shown in FIGS. 1, 2 and 3, in some embodiments, the driving assembly 130 is located in the lifting arm 122.

[0072] The driving assembly 130 is located in the lifting arm 122, which helps to reduce the size of the strip polishing mechanism 100 in the lifting direction, reduces the space occupation of the strip polishing mechanism 100 in the lifting direction, and facilitates the installation of the strip polishing mechanism 100.

[0073] In some embodiments, the lifting arm 122 and the electric lead screw 121 are arranged side by side.

[0074] like Figure 1 As shown, the lifting arm 122 and the electric lead screw 121 are not arranged sequentially along the length of the electric lead screw 121. The lifting arm 122 and the electric lead screw 121 are arranged side-by-side, which helps to reduce the size of the strip grinding mechanism 100 along the lifting direction, reduce the space occupied by the strip grinding mechanism 100 in the lifting direction, and facilitate the installation of the strip grinding mechanism 100. Specifically, the upper end of the lifting arm 122 is fixedly connected to the upper end of the lead screw of the electric lead screw 121.

[0075] The oilstone 300 applies excessive pressure to the strip steel, which can cause the oilstone 300 to scratch the strip steel surface. In some embodiments, the strip steel grinding mechanism 100 also includes a control system and a pressure sensor 150. The pressure sensor 150 and the motor of the electric lead screw 121 are both electrically connected to the control system. The pressure sensor 150 is located between the lifting arm 122 and the lead screw of the electric lead screw 121 to detect the downward pressure of the lifting arm 122, thereby obtaining the magnitude of the downward pressure applied by the oilstone 300 to the strip steel. The magnitude of the downward pressure is transmitted to the control system, which adjusts the motor action of the electric lead screw 121 according to the magnitude of the downward pressure, so that the value of the downward pressure meets the set requirements, avoiding excessive pressure applied by the oilstone 300 to the strip steel, which could cause the oilstone 300 to scratch the strip steel surface.

[0076] In some embodiments, the strip grinding mechanism 100 further includes a laser rangefinder 160, which is electrically connected to the control system. The laser rangefinder 160 is used to detect the distance between the oilstone 300 and the strip surface, and feeds the detected distance value back to the control system. The control system can adjust the motor action of the electric lead screw 121 according to the distance value, so that the oilstone 300 contacts or separates from the strip.

[0077] like Figure 7As shown, based on the same inventive concept, the embodiment of the present application further provides a strip steel polishing system 1000, comprising a supporting mechanism 200 and the above-mentioned strip steel polishing mechanism 100. The supporting mechanism 200 comprises a first sliding rail 210, a second sliding rail 220, a first driving member 230 and a second driving member 240.
