DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0030] Reference Figure 1-6 As shown, this embodiment provides a tank body grinding device, comprising:

[0031] A base 1, on which a grinding frame 2 is arranged;

[0032] The support mechanism includes two support frames 3 arranged on the base 1, and the support frames 3 are provided with support components for supporting the tank body 6; the support components include two support rods 4 symmetrically connected to the support frames 3, and the top ends of the support rods 4 are in rolling contact with the tank body 6; the two support rods 4 are connected to the side away from each other by rotation with an oblique support rod 5, and the oblique support rod 5 is slidably connected to the support frame 3;

[0033] The grinding mechanism includes a guide assembly arranged on the grinding frame 2, a grinding assembly is arranged on the guide assembly, and the grinding assembly is arranged in contact with the tank body 6; a positioning assembly is arranged at one end of the guide assembly facing the tank body 6, and the positioning assembly is arranged in contact with the tank body 6.

[0034] When in use, the tank body 6 to be polished is placed between the two support frames 3, and the two ends of the tank body 6 are in contact with the top of the support rod 4 of the support assembly. The tank body 6 generates pressure on the support rod 4, so that the diagonal support rod 5 rotatably connected to the support rod 4 slides on the support frame 3, and finally balances, thereby supporting tank bodies 6 with different outer diameters and different weights. It has stronger applicability, reduces the types of polishing equipment required for production, and avoids the problem of reduced production efficiency caused by replacing the supporting mechanism; a guide assembly is provided on the polishing frame 2, which is used to drive the polishing assembly below to polish along the outer wall of the tank body 6 without leaving dead angles, and the positioning assembly is used to position the distance between the polishing assembly and the tank body 6, adjust the polishing force of the polishing assembly, control the polishing effect, realize quantitative polishing of the outer wall of the tank body 6, and avoid the problem of uneven polishing.

[0035] To further optimize the solution, the bottom end of the diagonal support rod 5 is rotatably connected to a slider 7, and the slider 7 is slidably connected to a slider 8 fixed to the support frame 3; a support spring 9 is sleeved on the slider 8, and the two ends of the support spring 9 are respectively fixed to the support frame 3 and the slider 7; two symmetrically arranged slide grooves 10 are opened at the top of the support frame 3, and the slide rod 8 is arranged in the slide groove 10; the slider 7 is slidably connected in the slide groove 10. When the tank body 6 is placed on the supporting assembly, its outer wall contacts the top end of the supporting rod 4. Since the supporting rod 4 is initially tilted to both sides, it opens to both sides after being subjected to force. The angle between the diagonal supporting rod 5 and the supporting rod 4 changes, driving the sliding block 7 to slide on the sliding rod 8, compressing the supporting spring 9 until the force of the supporting spring 9 on the diagonal supporting rod 5 is balanced with the force of the tank body 6 on the supporting rod 4, thereby achieving the fixing of the tank body 6. The change of the supporting rod 4 is an infinite change rather than a step-by-step change. There is no need to prepare a variety of supporting structures that are suitable for the sizes of the tank body 6. Various types of tank bodies 6 can be adapted within the applicable range without replacement and adjustment, thereby achieving automatic support and fixation.

[0036] In a further optimized solution, a support groove 11 is provided at the top of the support rod 4, a support wheel 12 is rotatably connected in the support groove 11, the outer edge of the support wheel 12 extends out of the support groove 11 and is in rolling contact with the tank body 6; the support wheel 12 is in transmission connection with a first motor 13 provided on the support rod 4. The first motor 13 drives the support wheel 12 to rotate, and then drives the tank body 6 to rotate by friction, so that the grinding assembly can grind all parts of the outer wall of the tank body 6 without leaving any dead angle for grinding.

[0037] Furthermore, in order to prevent slipping between the tank body 6 and the support wheel 12, an anti-skid layer is applied on the outer wall of the support wheel 12 to increase the friction coefficient and avoid slipping.

The second motor 15 drives the driving rod 14 to rotate, thereby causing the first guide block 16 threadedly connected to the driving rod 14 to slide, thereby driving the telescopic rod 17 below and the grinding assembly and the positioning assembly below the telescopic rod 17 to move, so as to grind the outer wall of the tank body 6; the telescopic rod 17 is used to drive the grinding assembly and the positioning assembly to move longitudinally, control their longitudinal position and the size of the contact force with the tank body 6, and control the grinding effect.

[0039] Furthermore, in order to ensure the stability of the first guide block 16, a plurality of guide rods 30 are provided on both sides of the driving rod 14 and are arranged parallel to the driving rod 14. The guide rod 30 is fixed to the grinding frame 2, and the first guide block 16 is slidably connected to the guide rod 30 to stabilize the guide rod 30 and prevent the guide rod 30 from shaking.

[0040] Furthermore, the output end of the telescopic rod 17 is fixedly connected to a mounting plate 31 , and the grinding assembly and the positioning assembly are fixedly connected to the mounting plate 31 .

When grinding is required, the telescopic rod 17 drives the positioning tube 18 to descend until the ball 22 at the bottom of the positioning rod 21 contacts the top of the tank body 6, and continues to press down. The positioning rod 21 rises along the positioning tube 18, and the pressure sensor 19 is compressed by the positioning spring 20 to measure the pressure between the ball 22 and the tank body 6. The pressure sensor 19 compares the measured pressure with the preset grinding pressure, and then controls the extension and retraction of the telescopic rod 17; the ball 22 is provided to reduce the friction between the positioning rod 21 and the tank body 6, reduce the wear of the positioning rod, and reduce the measurement error.

[0042] Furthermore, the grinding assembly includes a grinding motor 32 fixed to the bottom end of the mounting plate 31, and the output end of the grinding motor 32 is transmission-connected to a grinding wheel 33 for grinding the surface of the tank body 6; the surface where the grinding wheel 33 contacts the tank body 6 is flush with the ball 22, which facilitates positioning.

[0043] Further optimization scheme, the bottom end of any support frame 3 is fixed with an adjustment block 23 and a second guide block 24, and the base 1 is provided with an adjustment groove 25 and a guide groove 26 respectively connected to the adjustment block 23 and the second guide block 24 in a sliding manner, and the adjustment block 23 is connected in a sliding manner in the adjustment groove 25, and the second guide block 24 is connected in a sliding manner in the guide groove 26.
