[0004] During the painting process of the existing plug valve, since the outer surface of the plug valve is an irregular shape as a whole, and the paint is applied to the surface of the plug valve by atomized spraying, the distance between the existing painting device and the spray gun nozzle is fixed, and the overall structure is fixed, which cannot ensure that the surface of the plug valve can be painted without dead angles during the painting process.

And although manual painting can avoid the above problems, its efficiency is low and the labor intensity is high.

[0034] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further introduced in detail below with reference to the accompanying drawings.

[0035] The present invention provides a Figures 1-9 plug valve painting tooling with a rotating mechanism as shown in the figure, including a carrier table 001, a placing frame 101 is installed above the carrier table 001, a protective plate 102 is installed on one side above the placing frame 101, and a paint spray head 103 is arranged between the lower part of the protective plate 102 and the inside of the placing frame 101;

[0036] The atomization of the paint can be realized through the paint spray head 103, and the protective plate 102 can provide protection to prevent paint splashing and dust particles from entering the placing frame 101.

[0037] The rotating assembly 002 arranged in the placing frame 101 includes a sliding cavity 201, the sliding cavity 201 is symmetrically opened on the inner wall of the placing frame 101, guide grooves 202 are symmetrically opened on the inner walls of the two groups of sliding cavities 201, moving seats 203 are arranged in the two groups of sliding cavities 201, guide blocks 204 are symmetrically installed on the two groups of moving seats 203, and the guide blocks 204 are slidably connected with the corresponding guide grooves 202. A lifting electric push rod 206 is installed between the moving seat 203 and the lower part of the inner wall of the sliding cavity 201. One side of a group of moving seats 203 is rotatably connected with a rotating cylinder 207, and the rotating cylinder 207 is located below the protective plate 102;

[0038] The lifting electric push rod 206 can drive the moving seat 203 to move up and down in the sliding cavity 201. The cooperation between the guide block 204 and the guide groove 202 can make the sliding of the moving seat 203 more stable, and the rotating cylinder 207 can move up and down following the moving seat 203.

[0039] The fixing component 003 arranged in the rotating cylinder 207 includes a through hole 302. The through holes 302 are annularly distributed and opened on the inner wall of the rotating cylinder 207, and are arranged in multiple groups in sequence. An annular cavity two 303 is opened on the inner wall of each group of through holes 302. A fixing rod 304 is connected through the through hole 302. A fixing ring 305 is sleeved and fixed on the fixing rod 304, and the fixing ring 305 is slidably connected with the corresponding annular cavity two 303. A return spring two 306 is sleeved on the fixing rod 304, and both sides of the return spring two 306 are respectively in contact with the fixing ring 305 and the annular cavity two 303.

[0040] Through the cooperation of the return spring two 306 and the fixing ring 305, the position of the fixing rod 304 in the through hole 302 is maintained. When the fixing rod 304 moves in the through hole 302, it can squeeze the return spring two 306. After the fixing rod 304 extends outward along the through hole 302, it finally fits against the inner wall of the plug valve, thus achieving a fixing effect.

[0041] The uniform spraying component 004 arranged in the placing frame 101 includes a reciprocating screw rod 401. The reciprocating screw rod 401 is rotatably connected in the placing frame 101. A reciprocating internal thread block 402 is screwed on the reciprocating screw rod 401, and a paint spray head 103 is arranged below the reciprocating internal thread block 402. A laser rangefinder 405 is installed below the reciprocating internal thread block 402. A first toothed belt wheel 406 is rotatably connected to the outside of the placing frame 101, and the first toothed belt wheel 406 is axially connected with the reciprocating screw rod 401.

[0042] The rotation of the reciprocating screw rod 401 can drive the reciprocating internal thread block 402 to perform a reciprocating motion, so as to move and atomize the paint spray head 103 for spraying. The laser rangefinder 405 can detect the distance between the paint spray head 103 and the plug valve, and through the lifting of the lifting electric push rod 206, the distance between the plug valves is fixed, ensuring the uniformity of the spraying thickness.

[0043] The power component 005 arranged on the outside of the placing frame 101 includes a fixing frame 501. The fixing frame 501 is installed on one side of the moving seat 203 connected with the rotating cylinder 207. A second toothed belt wheel 502 is rotatably connected between the fixing frames 501, and the second toothed belt wheel 502 is axially connected with the rotating cylinder 207. A motor 503 is installed on one side of the fixing frame 501, and the output end of the motor 503 is axially connected with the second toothed belt wheel 502.

[0044] The motor 503 can drive the second toothed belt pulley 502 to rotate, thereby rotating the rotating cylinder 207.

[0045] Furthermore, in the above structure, the rotating assembly 002 further includes a fixed electric push rod 205. The fixed electric push rod 205 is installed on one side of another set of moving seats 203, and the output end of the fixed electric push rod 205 and the rotating cylinder 207 are at the same horizontal position within the placement frame 101.

[0046] Furthermore, in the above structure, a limiting rod 208 is installed on the inner wall of the rotating cylinder 207. A push shaft 209 is connected through the rotating cylinder 207. One end of the push shaft 209 is provided with a first limiting hole 210, and the first limiting hole 210 is in limiting sliding connection with the limiting rod 208. A first return spring 211 is sleeved on the limiting rod 208, and both sides of the first return spring 211 are respectively in contact with the push shaft 209 and the inner wall of the rotating cylinder 207.

[0047] The first return spring 211 can keep the position of the push shaft 209, and the push shaft 209 can move after being subjected to pressure, squeezing the first return spring 211.

[0048] Furthermore, in the above structure, a limiting ring 212 is fixedly sleeved on the side of the push shaft 209 away from the first limiting hole 210. A first annular cavity 213 is opened on the inner wall of the rotating cylinder 207, and the first annular cavity 213 is in sliding connection with the limiting ring 212. One end of the push shaft 209 away from the first limiting hole 210 is rotatably connected with a rotating seat 214, and the rotating seat 214 is arranged opposite to the output end of the fixed electric push rod 205.

[0049] Through the telescoping of the fixed electric push rod 205, the rotating seat 214 is squeezed, thereby pushing the push shaft 209 to move within the rotating cylinder 207. And at this time, the rotating cylinder 207 is not affected and can still rotate.

[0050] Furthermore, in the above structure, the fixing component 003 further includes a trapezoidal annular groove 301. The trapezoidal annular groove 301 is sequentially opened on the surface of the push shaft 209, and the inner wall of the trapezoidal annular groove 301 is in contact with one end of the corresponding fixing rod 304. Annular positioning grooves 312 are sequentially opened on the surface of the push shaft 209, and the annular positioning grooves 312 are sequentially located between each group of trapezoidal annular grooves 301.

[0051] Through the movement of the push shaft 209, the trapezoidal annular groove 301 squeezes one end of the fixing rod 304, so that the fixing rod 304 extends outward along the through hole 302. At this time, one end of the fixing rod 304 can be in contact with the inside of the annular positioning groove 312.

[0052] Further, in the above structure, a second limiting hole 307 is formed at one end of each fixing rod 304 away from the trapezoidal annular groove 301. A limiting cavity 308 is formed on the inner wall of the second limiting hole 307. A fixing block 309 is connected through the second limiting hole 307. A limiting plate 310 is installed on one side of the fixing block 309. The limiting plate 310 is slidably connected to the limiting cavity 308. A first buffer spring 311 is attached between the limiting plate 310 and the inner wall of the second limiting hole 307.

[0053] The first buffer spring 311 can keep the position of the fixing block 309 in the fixing rod 304. After the fixing rod 304 extends outwards, the fixing block 309 can be attached to the inner wall of the plug valve. And the first buffer spring 311 will be compressed during this process, so as to prevent the fixing block 309 from damaging the inner wall of the plug valve, thus completing the socket fixing of the plug valve and the rotating cylinder 207.

[0054] Further, in the above structure, the uniform spraying assembly 004 further includes a limiting block 403. The limiting block 403 is installed above the reciprocating internal thread block 402. A limiting slide rail 404 is installed below the protection plate 102. The limiting slide rail 404 is slidably connected to the limiting block 403.

[0055] Through the cooperation of the limiting slide rail 404 and the limiting block 403, the reciprocating internal thread block 402 can run more smoothly.

[0056] Further, in the above structure, the power assembly 005 further includes a sliding cavity 504. The sliding cavity 504 is formed on the outer side of the placement frame 101. A guide rod 505 is installed on the inner wall of the sliding cavity 504. A sliding block 506 is sleeved on the guide rod 505. A second buffer spring 509 is sleeved on the guide rod 505. The two sides of the second buffer spring 509 are respectively attached to the sliding block 506 and the inner wall of the sliding cavity 504.

[0057] The second buffer spring 509 can keep the position of the sliding block 506 on the guide rod 505.

[0058] Further, in the above structure, a third toothed belt wheel 507 is rotatably connected to one side of the sliding block 506. A toothed belt 508 is attached between the third toothed belt wheel 507, the second toothed belt wheel 502 and the first toothed belt wheel 406.

[0059] By keeping the position of the sliding block 506, the toothed belt 508 is always in a taut state. And as the second toothed belt wheel 502 slides up and down, the sliding block 506 slides along the guide rod 505 to compress the second buffer spring509, so that the third toothed belt wheel 507 moves. After the second toothed belt wheel 502 resets, the sliding block 506 will also reset along, so that the toothed belt 508 can be used normally.

[0060] Such asFigures 1-9 As shown, by sleeving the plug valve onto the rotary drum 207, at this time, the output end of the fixed electric push rod 205 is used to squeeze the rotating seat 214, so that the push shaft 209 moves, thereby driving the annular positioning groove 312 by the push shaft 209 to squeeze the fixed rod 304. Finally, the annular positioning groove 312 fits with one end of the fixed rod 304. At the same time, the fixed block 309 at the other end of the fixed rod 304 fits with the inner wall of the plug valve, thus completing the fixation of the entire plug valve. At this time, the motor 503 is started to drive the plug valve to rotate by the rotary drum 207. At the same time, the reciprocating screw rod 401 above drives the reciprocating internal thread block 402 to move, and at the same time, the paint spray head 103 sprays paint. In this way, the moving spraying of the paint spray head 103 can be realized. During the moving process, the laser rangefinder 405 can detect the distance between the paint spray head 103 and the surface of the plug valve, and adjust the position of the rotary drum 207 by the lifting electric push rod 206 according to the set threshold, so as to ensure that the distance between the surface of the plug valve and the paint spray head 103 is always fixed. And during the up and down adjustment process, the third toothed belt pulley 507 can ensure that the toothed belt 508 is always tight, thus ensuring the transmission of power. Through this structure, the plug valve can rotate during the painting process to achieve all-round painting, and the painting spacing can be automatically adjusted according to the moving progress of the painting, so as to improve the uniformity of painting and the quality of painting.

[0061] Only some exemplary embodiments of the present invention have been described above by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways.
