[0062] Example

[0063] Please refer to Figure 1-Figure 15 The present embodiment provides a steel pipe surface polishing treatment device, comprising: a polishing mechanism 1000 and a driving mechanism 2000; wherein the polishing mechanism 1000 comprises a polishing component 100, a polishing component 200 and a supporting component 300; along the movement direction of the steel pipe 3000, the polishing component 100 and the polishing component 200 are sequentially arranged on the supporting component 300; the polishing component 100 can be used to polish the surface of the steel pipe 3000, and the polishing component 200 is used to polish the surface of the steel pipe 3000; the driving mechanism 2000 is used to drive the polishing component 200 and / or the polishing component 100 to move.

[0064] It should be noted that the polishing component 200 is in continuous operation, so the steel pipe 3000 must be polished, while the grinding component 100 can be used or not, depending on the actual working situation.

[0065] Another thing to be explained is that the driving mechanism 2000 can drive the grinding component 100 and the polishing component 200 to work simultaneously, and can also drive only the polishing component 200 to work, thereby realizing the selection of two working modes: polishing / grinding and polishing.

[0066] Through the above design, the driving mechanism 2000 can be used to drive the grinding component 100 and the polishing component 200 to work at the same time, or it can only drive the polishing component 200 to work, thereby realizing the selection of two working modes: polishing / grinding and polishing, thereby greatly improving work efficiency. There is no need to transfer the steel pipe 3000, and no additional grinding equipment is required, thereby reducing costs.

[0067] In general, the surface polishing equipment for the steel pipe 3000 provided in the embodiment of the present invention integrates grinding and polishing into one, which greatly improves the processing efficiency, reduces the processing cost, and improves the working effect of the surface treatment of the steel pipe 3000.

[0068] Specifically, in this embodiment, the polishing member 200 includes: a support tube 210, a driving gear 220 and a polishing assembly. Along the circumference of the support tube 210, the support tube 210 is movably connected with the support member 300; the support tube 210 is coaxially arranged with the steel tube 3000, and the steel tube 3000 can pass through the inner cavity of the support tube 210;

[0069] The driving gear 220 is disposed at one end of the support tube 210 close to the grinding component 100 , and the polishing assembly is rotatably disposed on the support component 300 ; the steel pipe 3000 enters the inner cavity of the support tube 210 after being polished by the polishing assembly.

[0070] The polishing assembly includes: a support shaft 231, a driven gear 232 and a polishing wheel 233. The support shaft 231 is rotatably arranged on the support member 300. The driven gear 232 and the polishing wheel 233 are both arranged on the support shaft 231, and the driven gear 232 is meshed with the driving gear 220. Along the circumference of the support tube 210, multiple polishing assemblies are evenly arranged.

[0071] It should be noted that the diameter of the support tube 210 is larger than the diameter of the processed steel tube 3000, and the steel tube 3000 is transported into the support tube 210 by a transport mechanism to ensure that the steel tube 3000 does not contact the inner wall of the support tube 210 when moving.

[0072] Another thing that needs to be explained is that one end of the support tube 210 passes through the side wall of the support member 300 and is connected to the driving gear 220 , and a bearing is installed between the support tube 210 and the support member 300 to ensure that the support tube 210 can rotate stably.

[0073] It should be noted that, in order to ensure that the polishing wheel 233 can be in close contact with the outer wall of the steel pipe 3000, the diameter of the polishing wheel 233 can be calculated and selected according to the diameter of the steel pipe 3000 to be processed, and the diameter of the circle formed by the multiple polishing wheels 233 is not greater than the diameter of the steel pipe 3000. This is a conventional technical means of those skilled in the art and will not be elaborated here.

[0074] In addition, in order to be able to adjust the diameter of the circle formed by multiple polishing wheels 233, the transmission method of the driving gear 220 and the driven gear 232 can also be changed to pulley transmission / chain transmission. At this time, an adjustment groove is opened on the side wall of the support member 300, and the central axis of the adjustment groove passes through the center of the steel pipe 3000. The support shaft 231 can be moved and fixed along the length direction of the adjustment groove, so as to realize the adjustment of the position of the polishing wheel 233. This adjustment method can refer to the adjustment method of the tensioning device, which is a conventional technical means in this field and will not be described here one by one.

[0075] Through the above design, the driving gear 220 can be driven to rotate by the support tube 210, and the driving gear 220 meshes with the driven gear 232, so that the polishing wheel 233 can rotate, thereby achieving polishing of the surface of the steel pipe 3000.

[0076] Specifically, in this embodiment, the grinding component 100 includes a rotating disk 110 and a grinding assembly 120. The rotating disk 110 is rotatably disposed on the supporting component 300. The supporting component 300 and the rotating disk 110 are respectively provided with a first material passage 310 and a second material passage 130 for the steel pipe 3000 to pass through.

[0077] A strip groove 140 for mounting the grinding assembly 120 is provided on one side of the rotating disk 110 away from the polishing member 200. One end of the strip groove 140 is close to the edge of the rotating disk 110, and the other end extends along the circumference of the rotating disk 110 and is close to the second material transfer channel 130. Along the length direction of the strip groove 140, the grinding assembly 120 is slidably connected to the strip groove.

[0078] The support member 300 is provided with a strip-shaped limiting hole 320, and the extension line of the strip-shaped limiting hole 320 in the length direction passes through the center of the first material passing channel 310; the grinding assembly 120 passes through the strip-shaped limiting hole 320, and along the length direction of the strip-shaped limiting hole 320, the grinding assembly 120 is slidably connected with the strip-shaped limiting hole 320;

[0079] The rotating disk 110 rotates to drive the grinding assembly 120 to move along the length direction of the strip-shaped limiting hole 320 to approach / move away from the steel pipe 3000 .

[0080] In addition, the grinding assembly 120 includes: a supporting block 121, a grinding wheel 122 and a limiting block 123. The supporting block 121 is slidably connected to the strip-shaped limiting hole 320. The limiting block 123 is arranged on the supporting block 121, and the limiting block 123 is slidably connected to the strip-shaped groove. The grinding wheel 122 is arranged on the side of the supporting block 121 away from the rotating disk 110.

[0081] It should be noted that the strip grooves may be of an arc-shaped structure or of a straight strip shape.

[0082] Another thing to note is that, in order to improve the grinding efficiency, multiple grinding assemblies 120 can be provided, and the number of strip grooves and strip limiting holes 320 matches the number of grinding assemblies 120. With the central axis of the first material transfer channel 310 as the axis, multiple grinding assemblies 120 are distributed in a circular array.

[0083] The rotating disk 110 can be used to rotate so that the limit block 123 moves along the length direction of the strip groove. Due to the special design of the strip groove, it has a certain vertical drop, and under the action of the strip limit hole 320, the supporting block 121 is displaced along the length direction of the strip limit hole 320, so that the grinding wheel 122 is close to / away from the steel pipe 3000. Under the joint action of multiple grinding components 120, multiple grinding wheels 122 gather to the side where the steel pipe 3000 is located to clamp the steel pipe 3000. When the steel pipe 3000 is rotated and transported, the grinding of the steel pipe 3000 is achieved; when the steel pipe 3000 does not need to be polished, the rotating disk 110 can be driven to rotate in the opposite direction. At this time, the multiple grinding wheels 122 are away from the steel pipe 3000 and separated from the steel pipe 3000.

[0084] Through the above design, the grinding assembly 120 can be switched between working mode and non-working mode to meet the processing requirements of different steel pipes 3000, greatly reducing the cost and eliminating the need to transfer equipment, thereby greatly improving convenience.

[0085] In addition, in order to facilitate driving the rotating disk 110 to rotate, a driving assembly 150 is specially added in this embodiment. The driving assembly 150 includes a driving worm wheel 151 and a driving worm 152. The driving worm wheel 151 is connected to the side of the rotating disk 110 away from the grinding wheel 122, and is coaxially arranged with the rotating disk 110. The driving worm wheel 151 is provided with a third material transfer channel, and the third material transfer channel is coaxial with the driving worm wheel 151.

[0086] The driving worm 152 is rotatably disposed on the supporting member 300 , and the driving worm 152 is meshed with the driving worm wheel 151 . The driving worm 152 rotates to drive the driving worm wheel 151 and the rotating disk 110 to rotate synchronously.

[0087] It should be noted that the worm gear structure is adopted based on its self-locking characteristics. Since the grinding wheel 122 is in contact with the steel pipe 3000, a certain reverse force may be generated during the grinding process, causing the supporting block 121 to move toward the side away from the steel pipe 3000, affecting the grinding effect. Therefore, a worm gear structure is adopted. When the driving worm 152 rotates to drive the driving worm wheel 151 and the rotating disk 110 to rotate to the ideal position, it will automatically lock, thereby ensuring that the position of the grinding wheel 122 does not change.

[0088] In this embodiment, the driving mechanism 2000 includes a driving disk 2100 and a transmission assembly 2200. The driving disk 2100 and the supporting member 300 can be rotatably disposed on the frame 4000, and one end of the supporting tube 210 away from the supporting member 300 passes through the driving disk 2100. The transmission assembly 2200 can be connected to the driving disk 2100 to drive the polishing member 200 and / or the grinding member 100 to move.

[0089] The transmission assembly 2200 includes a first meshing ring 2210 and a second meshing ring 2220. Along the central axis direction of the support tube 210, the first meshing ring 2210 is movably connected to the driving disk 2100; the second meshing ring 2220 is connected to the support member 300, and the central axis of the second meshing ring 2220 coincides with the central axis of the support tube 210.

[0090] The first meshing ring 2210 is provided with meshing grooves 2230 along its axial direction; along the circumference of the first meshing ring 2210, a plurality of meshing grooves 2230 are evenly distributed; a second meshing ring 2220 is provided with a plurality of position-limiting teeth 2240 matching with the plurality of meshing grooves 2230 on one side close to the first meshing ring 2210;

[0091] When the first meshing ring 2210 and the second meshing ring 2220 are meshed, the driving disk 2100 rotates and drives the supporting member 300 to rotate.

[0092] It should be noted that the center axis direction of the limiting tooth 2240 coincides with the center axis direction of the meshing groove 2230 , thereby ensuring that the limiting tooth 2240 and the meshing groove 2230 can mesh.

[0093] Another thing that needs to be explained is that, since the driving disk 2100 keeps rotating during operation, it is necessary to first suspend its operation when the transmission assembly 2200 is connected to keep it still so as to facilitate the engagement of the first meshing ring 2210 and the second meshing ring 2220 .

[0094] It should be noted that, in some embodiments, the steel pipe 3000 is conveyed in a rotating manner, that is, it is conveyed in a straight line during rotation. At this time, the polishing component 200 rotates, while the grinding component 100 remains fixed to achieve grinding and polishing.

[0095] In some other embodiments, the steel pipe 3000 is only transported in a straight line without rotation. In this case, the first meshing circle 2210 and the second meshing circle 2220 can be meshed through the transmission assembly 2200, thereby transmitting the rotational force to the support member 300, thereby driving the support member 300 to rotate, and then making the polishing assembly and the grinding assembly 120 revolve around the rotation center axis of the support pipe 210, thereby realizing rotation around the steel pipe 3000 and realizing polishing and grinding.

[0096] In addition, the radius of the driven gear 232 is smaller than the driving gear 220, so it is an acceleration structure, so that the rotation speed of the polishing wheel 233 is greater than the revolution speed of the polishing component, and its rotation and revolution directions are opposite, thereby improving the polishing efficiency.

[0097] Specifically, the transmission assembly 2200 also includes: a support portion 2250, a support column 2260 and a transmission screw 2270. The driving disk 2100 is provided with a movable hole 2280 matching the support column 2260. Along the axial direction of the support column 2260, the support column 2260 is movably connected to the movable hole 2280; one end of the support column 2260 is connected to the first meshing ring 2210, and the other end is connected to the support portion 2250. The support portion 2250 is provided with a through hole for facilitating the passage of the support tube 210, as well as a threaded hole 2290 matching the transmission screw 2270. After one end of the transmission screw 2270 passes through the threaded hole 2290, it is rotatably connected to the driving disk 2100.

[0098] It should be noted that, in order to ensure the stability of the support portion 2250 , a plurality of support columns 2260 may be provided, and the plurality of support columns 2260 are evenly distributed along the circumference of the first meshing ring 2210 .

[0099] Another thing that needs to be explained is that the rotation of the drive disk 2100 can be achieved through a conventional drive structure in the prior art, which will not be elaborated here.

[0100] The first meshing ring 2210 can be driven to move axially along the support tube 210 by rotating the transmission screw 2270, so that the first meshing ring 2210 and the second meshing ring 2220 are meshed, and the rotational force is transmitted to the support member 300, so that the support member 300 rotates, realizing the revolution of the grinding assembly 120 and the polishing assembly.

[0101] Through the above design, the driving disk 2100 can drive the support tube 210 to rotate, thereby driving the polishing assembly to rotate, and the rotational force can be transmitted to the support member 300 through the transmission assembly 2200, so that the polishing assembly and the grinding assembly 120 revolve, thereby greatly improving the grinding and polishing efficiency.

[0102] The working principle of a steel pipe 3000 surface polishing equipment is:

[0103] (1) When only polishing is required, one end of the steel pipe 3000 is inserted into the first material transfer channel 310 and is conveyed linearly while rotating. At this time, the driving disc 2100 rotates to drive the support tube 210 to rotate, driving the driving gear 220 to rotate and mesh with the driven gear 232, thereby causing the multiple polishing wheels 233 to rotate, thereby achieving polishing of the steel pipe 3000;

[0104] (2) When the steel pipe 3000 is conveyed in a linear manner without rotation, the rotating transmission screw 2270 drives the first meshing circle 2210 to move toward the second meshing circle 2220 until they mesh with each other. At this time, the driving disk 2100 rotates to drive the support tube 210 to rotate, and drives the driving gear 220 to rotate and mesh with the driven gear 232, thereby causing the multiple polishing wheels 233 to rotate. At the same time, the supporting member 300 rotates synchronously with the driving disk 2100, so that the multiple polishing components revolve around the steel pipe 3000 as the axis, thereby achieving polishing of the steel pipe 3000;

[0105] (3) When grinding and polishing are required, first rotate the driving worm 152 to drive the driving worm wheel 151 to rotate, so that the supporting block 121 moves toward the steel pipe 3000 until the grinding wheel 122 contacts the steel pipe 3000; then rotate the transmission screw 2270 to drive the first meshing circle 2210 to move toward the second meshing circle 2220 until they mesh with each other. At this time, the supporting member 300 rotates synchronously with the driving disk 2100, the polishing assembly realizes self-rotation and orbital revolution, and the grinding assembly 120 realizes orbital revolution.

[0106] In summary, the surface polishing equipment for the steel pipe 3000 provided by the present invention integrates grinding and polishing into one, greatly improves the processing efficiency, reduces the processing cost, and improves the working effect of the surface treatment of the steel pipe 3000.

[0107] In addition, this embodiment also provides a working method based on the above-mentioned polishing processing equipment, S1: conveying the processed steel pipe 3000 into the supporting member 300;

[0108] S2: The driving disc 2100 rotates to drive the support tube 210 and the driving gear 220 to rotate synchronously, so as to drive the polishing assembly to move, so as to polish the steel tube 3000;

[0109] S3: When grinding is required, the transmission screw 2270 is rotated to drive the first meshing circle 2210 to move toward the side where the second meshing circle 2220 is located, until the first meshing circle 2210 and the second meshing circle 2220 are meshed. At this time, the driving disk 2100 rotates to drive the support tube 210 to rotate while driving the support member 300 to rotate, so that the grinding member 100 and the polishing member 200 rotate.
