Description

Technical Field

[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and smooth surface. It is a modification process of the workpiece surface using polishing tools and abrasive particles or other polishing media. During polishing, a high-speed rotating polishing wheel (circumferential speed of more than 20 m / s) is pressed against the workpiece, causing the abrasive to roll and slightly cut the workpiece surface, thereby obtaining a bright processed surface.

[0003] When polishing the outer surface of the tank body, since the circumference of the tank body is a curved surface and the diameter is usually large, the common bracket adopts a straight steel frame structure, which is difficult to fit the curved surface of the tank body, and thus it is difficult to provide stable support for the tank body. As a result, when the tank body is rotated to polish the downward surface of the tank body, the tank body is easily rolled off the bracket and fell to the ground, causing damage to the tank body.

[0035] Reference Figure 1-6 ,

[0036] A tank polishing machine includes: a support wheel 1, a power device 2 and a polishing device 3. The support wheel 1 is a rubber wheel with a plurality of anti-skid grooves on the surface. Four groups of support wheels 1 are arranged. The four groups of support wheels 1 are respectively placed under the tank body. The wheel surfaces of the four groups of support wheels 1 are tangent to the outer circumference of the tank body to form a "four-point support". The power device 2 is connected to part of the support wheel 1, and is used to make part of the support wheel 1 rotate around the support wheel 1 itself. The support wheel 1 drives the tank body to rotate around the axis of the tank body, thereby rotating the downward part of the tank body for polishing. The polishing device 3 forms a rotating polishing curved surface, which is tangent to the outer circumference of the tank body, thereby polishing the outer surface of the tank body.

[0037] Specifically, it also includes: a rotating wheel 4 and a bracket 5. The bracket 5 is located on the side of the supporting wheel 1 facing away from the polishing device 3, and the bracket 5 is placed on the ground. The rotating wheel 4 is rotatably connected to the upper end of the bracket 5 through a bearing, and the axis of the rotating wheel 4 is perpendicular to the axis of the supporting wheel 1. The wheel surface of the rotating wheel 4 abuts against one end of the tank body to prevent the end of the tank body from touching the ground. Because the rotating wheel can rotate relative to the bracket 5, when the power device 2 rotates the tank body, the rotating wheel rotates relative to the bracket 5 to reduce friction with the surface of the tank body, thereby reducing wear on the surface of the tank body.

[0038] Specifically, it also includes: a rotating frame 6 and a base 7. The base 7 is placed on the ground, and the rotating frame 6 is rotatably connected to the base 7 through a pin shaft. Two groups of rotating frames 6 are provided, one group of rotating frames 6 is rotatably connected to two adjacent groups of support wheels 1 through a pin shaft, and the other group of rotating frames 6 is rotatably connected to the other two groups of support wheels 1 through a pin shaft, and the rotation axis of the rotating frame 6 is parallel to the axis of the support wheels 1. According to the different outer circumferential diameters of the tank body, when the tank body is placed on the four groups of support wheels 1, the rotating frame 6 will rotate relative to the base 7, so that the two groups of support wheels 1 on the same group of rotating frames 6 rotate around the pin shafts of the rotating frame 6 and the base 7, so that the support wheels 1 can always fit the surface of the tank body.

[0039] Specifically, a group of support wheels 1 includes two coaxial and parallel support wheels 1, a group of rotating frames 6 includes at least two rotating frames 6, the two rotating frames 6 are parallel to each other along the axis of the support wheel 1, and the two groups of rotating frames 6, a total of four rotating frames 6, form a four-point support for the tank body on the base 7, thereby improving the stability of the tank body support.

[0040] Specifically, the power device 2 includes: a first motor 8, a first gear plate 9, a second gear plate 10 and a chain 11. Two first gear plates 9 are provided, two second gear plates 10 are provided, and two chains 11 are provided. The first motor 8 is fixedly mounted on the base 7 by bolts, and the two first gear plates 9 are respectively fixed in series with the output end of the first motor 8 by flat keys. One second gear plate 10 is connected to a support wheel 1 by a pin shaft, and another second gear plate 10 is connected to another support wheel 1 by a pin shaft, and the two support wheels 1 are connected to the same rotating frame 6. A first toothed disc 9 forms a transmission relationship with a second toothed disc 10 through a chain 11, and another first toothed disc 9 forms a transmission relationship with another second toothed disc 10 through another chain 11. After the first motor 8 is started, the two first toothed discs 9 are turned, and one first toothed disc 9 drives a second toothed disc 10 to rotate through a chain 11, and the second toothed disc 10 drives a support wheel 1 to rotate; another first toothed disc 9 drives another second toothed disc 10 to rotate through another chain 11, and the second toothed disc 10 drives another support wheel 1 to rotate. Thus, the two support wheels 1 cooperate to drive the tank body to rotate.

[0041] Specifically, the polishing device 3 includes: a transverse moving assembly 12, a longitudinal moving assembly 13, a second motor 14, a transmission assembly 15 and a polishing wheel 16. The curved surface of the polishing wheel 16 forms a polishing curved surface, and the output end of the second motor 14 is connected to the polishing wheel 16 through the transmission assembly 15, so that the polishing wheel 16 rotates to polish the surface of the tank body. The housing of the second motor 14 is connected to the transverse moving assembly 12, and the transverse moving assembly 12 makes the second motor 14 approach and move away from the support wheel 1 along a movable straight line, and the movable straight line is parallel to the axis of the support wheel 1, so that the second motor 14 drives the polishing wheel 16 to move along the length direction of the tank body to polish the entire outer surface of the tank body. Due to the different circumferential diameters of different tank bodies, the height of the circumferential vertex of the polishing wheel 16 contacting the tank body is also different. The transverse moving assembly 12 is connected to the longitudinal moving assembly 13, and the longitudinal moving assembly 13 makes the transverse moving assembly 12 reciprocate up and down, so that the movable straight line reciprocates up and down, thereby adjusting the height of the polishing wheel 16.

[0042] Specifically, the transmission assembly 15 includes: a large pulley 17, a belt 18, a small pulley 19 and a rotating shaft 20. The large pulley 17 is fixedly connected to the output end of the second motor 14 through a flat key, the belt 18 is sleeved on the large pulley 17 and the small pulley 19, the small pulley 19 is fixedly connected to one end of the rotating shaft 20 through a flat key, and the other end of the rotating shaft 20 is fixedly connected to the polishing wheel 16 through a flat key. After the second motor 14 is started, the large pulley 17 is driven to rotate, and the large pulley 17 forms an acceleration transmission to the small pulley 19 through the belt 18, so that the small pulley 19 drives the polishing wheel 16 to rotate at a high speed through the rotating shaft 20.

[0043] Specifically, the longitudinal moving assembly 13 includes: a column 21, a third motor 22, a screw 23, a guide sleeve 24 and a nut 25. The guide sleeve 24 is slidably connected to the column 21, the nut 25 is welded and fixed on the guide sleeve 24, the nut 25 is threadedly connected to the screw 23, the screw 23 and the column 21 are both perpendicular to the ground, the third motor 22 is fixedly installed on the column 21 by bolts, the output end of the third motor 22 is connected to one end of the screw 23 by a coupling, and the other end of the screw is rotatably connected to the base 7. When the third motor 22 is started, the screw 23 is driven to rotate, and the nut 25 moves up and down along the screw 23, thereby driving the guide sleeve 24 to move up and down along the column 21.

[0044] Specifically, the transverse moving assembly 12 includes: a crossbar 26, a fourth motor 27, a support block 28 and a roller 29. The length of the crossbar 26 is reversely coincident with the movable straight line, the fourth motor 27 is fixedly mounted on the support block 28 by bolts, and multiple groups of rollers 29 are mounted on the support block 28 by pins, specifically four groups of rollers 29, two groups of rollers 29 contact the upper end of the crossbar 26, and two groups of rollers 29 contact the lower end of the crossbar 26 to support the crossbar 26. The output end of the fourth motor 27 is connected to a group of rollers 29 through a coupling, and one end of the crossbar 26 is connected to the housing of the second motor 14 by bolts. When the fourth motor 27 is started, a group of rollers 29 are driven to rotate, and the rollers 29 drive the crossbar 26 to reciprocate laterally along the movable straight line through friction.
