[0004] The clamping robot for mechanical parts processing places the robot body in the installation box for positioning, and then drives the threaded rod to rotate by turning the handle, so that when the threaded rod rotates, the threaded block drives the fixing frame and the limit block to descend, and at the same time the fixing frame is inserted into the extension block to fix the robot body to prevent the robot body from shaking, thereby facilitating the installation of the robot body.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figures 1 to 8As shown, a robot for processing mechanical parts comprises a base plate 1, a first motor 2 is fixedly mounted on the top of the base plate 1, a connecting block 21 is fixedly connected to the output shaft of the first motor 2, a first cantilever 22 is rotatably connected to one end of the connecting block 21, a second cantilever 23 is rotatably connected to the top of the first cantilever 22; a dust removal mechanism is also included for cleaning dust on mechanical parts; the dust removal mechanism comprises an air pump 3, a connecting rod 31 is fixedly connected to the top of the air pump 3, the connecting rod 31 is fixedly mounted on the bottom of the connecting block 21, a first connecting pipe 32 is fixedly connected to one side of the air pump 3, a conversion block 33 is fixedly connected to one end of the first connecting pipe 32, the conversion block 33 is fixedly mounted on the top of the second cantilever 23, a second connecting pipe 34 is fixedly connected to one side of the conversion block 33, and an air outlet head 351 is rotatably connected to one end of the second connecting pipe 34.

[0023] Existing mechanical parts have high requirements on precision, and existing manipulators directly clamp the mechanical parts, ignoring the treatment of dust on the surface of the mechanical parts.

[0024] When the present invention is in use, the position of the manipulator is adjusted by the second cantilever 23 and the first cantilever 22, and the output shaft of the first motor 2 further drives the connecting block 21, the first cantilever 22 and the second cantilever 23 to rotate, so that the manipulator can have a larger range of movement, and when the connecting block 21 rotates, the connecting block 21 will drive the air pump 3 to rotate through the connection of the connecting rod 31. Before the manipulator clamps the mechanical parts, high-pressure gas is generated by the air pump 3 and enters the conversion block 33 through the first connecting pipe 32. The gas in the conversion block 33 is then blown out through the second connecting pipe 34 and the air outlet head 351. At this time, the air outlet head 351 is aimed at the mechanical parts to blow off the dust on the mechanical parts. At this time, the clean parts can be clamped by the manipulator.

[0025] Further, such as Figure 2 As shown, four first mounting plates 11 are evenly fixedly installed on the outer surface of the base plate 1, a first groove 12 is opened on the top of the base plate 1, a first slider 13 is slidably installed on the inner surface of the first groove 12, the first slider 13 is fixedly installed on the bottom of the air pump 3, and three first mounting blocks 14 are fixedly installed on the top of the base plate 1, and the three first mounting blocks 14 are fixedly installed together on the bottom of the first motor 2.

[0026] When the present invention is in use, supporting the first motor 2 through the first mounting block 14 can increase the ventilation at the bottom of the first motor 2, thereby achieving the purpose of cooling the first motor 2. When working, the first slider 13 slides on the inner surface of the first groove 12 to increase the stability of the air pump 3 when sliding. During installation, the entire device can be fixed by four first mounting plates 11.

[0027] Further, such as Figure 3As shown, a second motor 221 is fixedly installed on one side of the connecting block 21, and the output shaft of the second motor 221 is fixedly connected to one side of the first cantilever 22. A third motor 231 is fixedly installed on one side of the first cantilever 22, and the output shaft of the third motor 231 is fixedly connected to one side of the second cantilever 23.

[0028] When the present invention is in use, the first cantilever 22 is rotated by the output shaft of the second motor 221, and the second cantilever 23 is rotated by the output shaft of the third motor 231. The angles between the first cantilever 22, the second cantilever 23 and the connecting block 21 and the first cantilever 22 are adjusted so that the device can grab mechanical parts at different positions.

[0029] Further, such as Figure 4 As shown, a fourth motor 241 is fixedly installed on one side of the second cantilever 23, and the output shaft of the fourth motor 241 is fixedly connected to one side of the rotating block 24. An electric telescopic rod 25 is fixedly connected to one end of the rotating block 24, and a clamping block 26 is fixedly connected to the output end of the electric telescopic rod 25.

[0030] When the present invention is in use, the gripping position can be further adjusted by rotating the rotating block 24 through the output shaft of the fourth motor 241 , and the gripping position can be further adjusted by extending or shortening the electric telescopic rod 25 .

[0031] Further, such as Figure 5 and Figure 6 As shown, a second groove 261 is provided on one side of the clamping block 26, and two third grooves 262 are provided on the inner surface of the second groove 261. A second slider 263 is slidably mounted on the inner surface of the third groove 262. A connecting plate 265 is fixedly connected to both sides of the second slider 263. Two first springs 266 are fixedly connected to the opposite surfaces of the two opposite second sliders 263. A triangular groove 264 is provided on the inner surface of the second groove 261. A clamping block 27 is movably installed on the inner surface of the triangular groove 264, and one end of the clamping block 27 is fixedly connected to a second mounting plate 271. Two fifth grooves 273 and a fourth groove 272 are provided on one side of the second mounting plate 271. A bidirectional threaded rod 274 is rotatably installed on the inner surface of the fourth groove 272, and one end of the bidirectional threaded rod 274 passes through the fourth groove 272 and is fixedly connected to a fifth motor 275. A guard plate 28 is slidably installed on one side of the second mounting plate 271, and the bidirectional threaded rod 274 is threadedly connected to the guard plate 28.

[0032] When the present invention is in use, the block 27 is installed on the inner surface of the triangular groove 264. During installation, the block 27 squeezes the two second sliders 263. The two second sliders 263 are respectively on the inner surfaces of the two third grooves 262. After the block 27 is installed into the inner surface of the triangular groove 264, under the action of the first spring 266, the two second sliders 263 are close to each other to restrain the block 27. This makes it easy for the staff to quickly disassemble and assemble the block 27 connected with the second mounting plate 271, thereby achieving the purpose of quick disassembly and assembly. When in use, the output shaft of the fifth motor 275 drives the bidirectional threaded rod 274 to rotate, and the bidirectional threaded rod 274 can drive the two guard plates 28 to move closer to or away from each other. By making the two guard plates 28 move closer to or away from each other, the mechanical parts can be clamped and prevented from loosening.

[0033] Further, such as Figure 7 As shown, two limit blocks 281 are fixedly installed on one side of the guard plate 28, and the two limit blocks 281 are slidably installed on the inner surfaces of the two fifth grooves 273 respectively. Four installation grooves 282 are opened on one side of the guard plate 28, and a telescopic rod 283 is fixedly installed on the inner surface of the installation groove 282. A second spring 284 is wound and installed on the outer surface of the telescopic rod 283. One end of the telescopic rod 283 and the second spring 284 are fixedly connected with a splint 285, and a plurality of friction pads 286 are fixedly installed on the opposite surfaces of the two splints 285.

[0034] When the present invention is in use, the two guard plates 28 are close to each other, and the friction pad 286 is in contact with the mechanical parts. The friction pad 286 increases the friction between the mechanical parts to prevent the mechanical parts from slipping after the mechanical parts are clamped. The telescopic rod 283 and the second spring 284 cooperate to prevent the force of the two guard plates 28 when moving from being directly transmitted to the mechanical parts and damaging the mechanical parts.

[0035] Further, such as Figure 8 As shown, a second mounting block 35 is fixedly mounted on the top of the second mounting plate 271, a sixth motor 354 is fixedly mounted on one side of the second mounting block 35, an output shaft of the sixth motor 354 passes through the second mounting block 35 and is fixedly connected to a second gear 353, the second gear 353 is rotatably mounted on one side of the sixth motor 354, the second gear 353 is meshed with a first gear 352, one end of the second connecting pipe 34 is fixedly mounted on one side of the second mounting block 35, the air outlet head 351 is rotatably mounted on the other side of the second mounting block 35, the second connecting pipe 34 is through-connected with the air outlet head 351, the first gear 352 is fixedly mounted on the outer surface of the air outlet head 351, a mounting frame 36 is fixedly mounted on the top of the second mounting block 35, a rotating groove 37 is opened at one end of the mounting frame 36, and a detector 371 is rotatably mounted on the inner surface of the rotating groove 37.

[0036] When the present invention is in use, the output shaft of the sixth motor 354 drives the second gear 353 to rotate, and the meshing of the second gear 353 with the first gear 352 can further drive the first gear 352 to rotate, and the first gear 352 drives the air outlet head 351 to rotate together, so that the mechanical parts can be blown as a whole, thereby avoiding blind spots on the mechanical parts that cannot be blown by the air outlet head 351, resulting in dust remaining on the mechanical parts; When in use, the second connecting tube 34 can be extended or shortened along with the electric telescopic rod 25 without affecting the use. The position of the mechanical parts can be detected first by the detector 371 so as to clamp the mechanical parts.

[0037] Working principle: First, the exact position of the mechanical parts is detected by the detector 371, and then the second motor 221, the third motor 231 and the fourth motor 241 cooperate to make the two guard plates 28 be on the top of the mechanical parts, and then the air pump 3 inputs high-pressure gas to the first connecting pipe 32, and the first connecting pipe 32 transmits it to the conversion block 33, and then it is transmitted through the conversion block 33 through the second connecting pipe 34, and the second connecting pipe 34 is connected to the air outlet head 351 to blow to the mechanical parts to remove dust from the surface of the mechanical parts. At the same time, the output shaft of the sixth motor 354 drives the second gear 353 to rotate, and the engagement of the second gear 353 with the first gear 352 enables the first gear 352 to rotate with the air outlet head 351, thereby further achieving the purpose of expanding the dust removal range of the air outlet head 351.

[0038] In order to increase the practicality of the manipulator during use, it is necessary to facilitate the replacement of the block 27 connected to the second mounting plate 271. When the block 27 needs to be installed during use, it is only necessary to insert the block 27 into the triangular groove 264. The two second sliders 263 cooperate with the first spring 266 to limit the block 27 in the inner cavity of the second groove 261, so as to achieve the purpose of quick disassembly and assembly. When clamping mechanical parts, the friction between the mechanical parts and the friction pad 286 is increased to prevent the parts from falling off. The telescopic rod 283 and the second spring 284 can prevent the friction pad 286 from causing excessive clamping force on the mechanical parts after contacting the mechanical parts, thereby causing damage to the mechanical parts. The second motor 221, the third motor 231 and the fourth motor 241 cooperate with the first cantilever 22 and the second cantilever 23 to adjust the position of the guard plate 28 and thus realize the grabbing of mechanical parts at different positions.
