Description

Technical Field

[0001] The present application relates to the technical field of power equipment, and in particular to a novel pneumatic motor. Background Art

[0002] In order to prevent excessive noise, current pneumatic motors generally install silencers at the air outlet of the motor. However, when the air motor changes speed, the silencer will affect the performance of its air outlet. Therefore, it is necessary to frequently replace different types of pneumatic motor silencers. However, the silencer of the pneumatic motor is generally connected to the air outlet of the pneumatic motor by threaded fixing. Frequent disassembly and assembly will cause thread wear or even damage, making it difficult to install the silencer at the air outlet of the pneumatic motor. At the same time, when the air pipe is inserted into the air inlet of the pneumatic motor, the air pipe is generally limited by the retaining spring lock at the air inlet of the pneumatic motor. However, the current retaining spring lock is relatively sharp and can easily puncture the air pipe, causing air leakage. At the same time, the retaining spring lock of the pneumatic motor will weaken the clamping force on the air pipe after long-term use, causing the air pipe to easily fall off from the air inlet.

[0003] On the other hand, by searching Chinese patent publication number CN110359962B, a pneumatic motor is disclosed. The device has a simple working condition and avoids the situation where the seal deteriorates or fails and causes the motor to be unable to start. At the same time, the output torque and speed are stable. However, during the storage of the pneumatic motor, some water vapor in the air pipe enters the inside of the pneumatic motor when the pneumatic motor is in use. If the rotating blades and the main shaft inside the motor are not oil-sealed, rust will be generated inside the pneumatic motor after long-term storage, affecting the speed of the motor. The rust on the inner wall of the motor will accelerate the wear of the rotating blades of the motor. In severe cases, the pneumatic motor may be stuck. At the same time, dust and water vapor will enter the inside of the motor through the air inlet and outlet during the storage of the pneumatic motor, affecting the service life of the motor.

[0004] Therefore, we provide a new type of pneumatic motor to solve the above problems. Summary of the invention

[0021] The following is combined with Figure 1-15 This application is described in further detail.

[0022] The present application discloses a novel pneumatic motor. Figure 1 , Figure 8 and Fig. 9As shown, it includes a pneumatic motor body shell 1, and a pneumatic mechanism 2 is arranged inside the pneumatic motor body shell 1. The pneumatic mechanism 2 includes a rotating eccentric roller 201, and the rotating eccentric roller 201 is rotatably connected to the pneumatic motor body shell 1. Five force-pushing plates 202 in a circumferential array are arranged inside the rotating eccentric roller 201. The five force-pushing plates 202 are all slidably connected to the rotating eccentric roller 201. Two first telescopic springs 203 are fixedly connected to each force-pushing plate 202, and each first telescopic spring 203 is fixedly connected to the rotating eccentric roller 201. A connecting base 205 is fixed on the pneumatic motor body shell 1. The rotating eccentric roller 201 is rotatably connected to the pneumatic motor body shell 1. One end of 01 is fixedly connected to a motor output shaft 204. After the air pipe is docked with the device, the circulating gas in the air pipe will rush to the force-pushing plate 202, and the force-pushing plate 202 will move under the influence of wind pressure, so that the five force-pushing plates 202 will drive the rotating eccentric roller 201 to rotate, so that the rotating eccentric roller 201 rotates around the motor output shaft 204. The rotation of the rotating eccentric roller 201 will drive the motor output shaft 204 to rotate, and the force-pushing plate 202 will pop out from the rotating eccentric roller 201 under the spring pressure of the first telescopic spring 203, so that the force-pushing plate 202 is always in contact with the inner wall of the pneumatic motor body casing 1.

[0023] like Fig.10 and Fig.11 As shown, a plug-in mechanism 3 is arranged above the air motor body shell 1, and the plug-in mechanism 3 includes a muffler 301 and a connecting pipe 302. The muffler 301 is installed on the connecting pipe 302, and the connecting pipe 302 is fixedly installed on the connecting base 205. Two mechanism slot boxes 303 are symmetrically fixed on the outer wall of the connecting pipe 302. The inner walls of the two mechanism slot boxes 303 are slidably connected with sealing rubber blocks 304. The two sealing rubber blocks 304 are fixedly connected with limited wedge blocks 305. The two limited wedge blocks 305 penetrate the connecting pipe 302 and are slidably connected to the connecting pipe 302. The outer surface of the muffler 301 is provided with two card grooves adapted to the limited wedge blocks 305. The two sealing rubber blocks 304 are fixedly connected There is a second telescopic spring 306, and the two second telescopic springs 306 are fixedly connected to the two mechanism slot boxes 303 respectively. The two sealing rubber blocks 304 are fixedly connected with a linkage long rod 307, and the two linkage long rods 307 are slidingly connected to the two mechanism slot boxes 303 respectively. By setting the second telescopic spring 306, when the muffler 301 is inserted into the connecting pipe 302, the muffler 301 will squeeze the two limiting wedge blocks 305 to separate from each other. After the card slot of the muffler 301 moves to the position corresponding to the limiting wedge block 305, the limiting wedge block 305 is reset under the spring pressure of the second telescopic spring 306, and the two limiting wedge blocks 305 pop out and engage with the muffler 301, completing the installation of the muffler 301.

[0024] The ends of the two linked long rods 307 are rotatably connected with hinged rods 308, and the outer side wall of the connecting base 205 is fixedly connected with a fixed U-shaped slide rail 310, and the inner wall of the fixed U-shaped slide rail 310 is slidably connected with a lifting handle block 309, and the two hinged rods 308 are hinged on the lifting handle block 309 through pins. When replacing the muffler 301, it is only necessary to pull the lifting handle block 309 upward so that the lifting handle block 309 drives the two linked long rods 307 away from each other through the two hinged rods 308, so that the two linked long rods 307 respectively drive the two limiting wedge blocks 305 to separate from each other, so that the two limiting wedge blocks 305 cancel the limiting effect on the muffler 301, and the muffler 301 can be directly taken out.

[0025] like Fig.12 , Fig.13 , Fig.14 and Fig.15 As shown, a docking mechanism 4 is arranged above the air motor body shell 1, and the docking mechanism 4 includes a plug-in sleeve member 401, and the plug-in sleeve member 401 is fixed on the connecting base 205. A conical anti-skid pipe seat 405 is arranged inside the plug-in sleeve member 401, and the conical anti-skid pipe seat 405 is fixedly installed on the connecting base 205. The outer surface of the conical anti-skid pipe seat 405 is sleeved with an inverted cone extrusion block 402, and the outer surface of the plug-in sleeve member 401 is fixedly connected to a limiting slide bar 403, and the inverted cone extrusion block 402 is slidably connected to the limiting slide bar 403. The outer surface of the limiting slide bar 403 is sleeved with a third telescopic spring 404, and the third telescopic spring 404 is fixedly connected between the inverted cone extrusion block 402 and the plug-in sleeve member 401, so that the air pipe is extended into the plug-in sleeve member 401. The sleeve member 401 is inserted into and plugged into the conical anti-skid tube seat 405, and the handle 411 is controlled to drive the inverted conical extrusion block 402 to move downward, so that the inverted conical extrusion block 402 cooperates with the conical anti-skid tube seat 405 to clamp the trachea and fix it on the conical anti-skid tube seat 405, and the inner wall of the inverted conical extrusion block 402 and the outer surface of the conical anti-skid tube seat 405 are both provided with anti-skid patterns to increase the friction between the trachea and the trachea. Through the setting of the third telescopic spring 404, after the inverted conical extrusion block 402 is not restricted, the inverted conical extrusion block 402 will be reset by the spring pressure of the third telescopic spring 404, so that the inverted conical extrusion block 402 is away from the conical anti-skid tube seat 405, thereby canceling the clamping of the trachea by the conical anti-skid tube seat 405 and the inverted conical extrusion block 402.

[0026] The outer surface of the inverted cone extrusion block 402 is fixedly connected with a movable sleeve 406, and the movable sleeve 406 is slidably connected to the plug-in sleeve member 401. The outer surface of the plug-in sleeve member 401 is fixedly connected with a ratchet 409, and the outer surface of the ratchet 409 is sleeved with a pulling handle 411, which is fixedly connected to the movable sleeve 406. Through the setting of the pulling handle 411, it is convenient for the staff to pull the pulling handle 411 to drive the inverted cone extrusion block 402 to move downward.

[0027] The inner wall of the movable sleeve 406 is slidably connected with a pawl 407, the pawl 407 is meshed with the ratchet bar 409, the pawl 407 is fixedly connected with a fourth telescopic spring 408, one end of the fourth telescopic spring 408 away from the pawl 407 is fixedly connected to the movable sleeve 406, and the pawl 407 is fixedly connected with a disengagement rod 410. Through the setting of the disengagement rod 410, the staff can conveniently cancel the meshing state of the pawl 407 and the ratchet bar 409 by pulling the disengagement rod 410. The disengagement rod 410 is slidably connected to the movable sleeve 406, and the control pull handle 411 drives the inverted cone extrusion block 402 to move downward, so that the inverted cone extrusion block 402 cooperates with the conical anti-slip tube seat 405 to clamp the trachea on the conical anti-slip tube seat 405. Due to the engagement of the pawl 407 and the ratchet bar 409, the pawl 407 will be blocked by the teeth of the ratchet bar 409, thereby preventing the movable sleeve 406 from moving upward, and then maintaining the connection between the conical anti-slip tube seat 405 and the trachea.

[0028] Two arc-shaped anti-sliding blocks 412 are symmetrically arranged inside the plug-in sleeve member 401, and two limiting rods 415 are fixedly connected to the inner wall of the plug-in sleeve member 401, and the two limiting rods 415 are slidably connected to the two arc-shaped anti-sliding blocks 412. Through the sliding relationship between the limiting rods 415 and the arc-shaped anti-sliding blocks 412, the stability of the arc-shaped anti-sliding blocks 412 during movement is increased, and the moving direction of the arc-shaped anti-sliding blocks 412 is limited. One-way threaded rods 413 are rotatably connected to the outer side walls of the two arc-shaped anti-sliding blocks 412, and two threaded tubes 414 are symmetrically fixed on the outer side wall of the plug-in sleeve member 401. The two threaded tubes 414 are respectively threadedly connected to the two one-way threaded rods 413. Rotating the one-way threaded rod 413 drives the arc-shaped anti-sliding block 412 to approach the trachea, so that the two arc-shaped anti-sliding blocks 412 clamp the trachea and fix it on the conical anti-slip pipe seat 405, to prevent the trachea from falling out of the conical anti-slip pipe seat 405.

[0029] like Figure 2 , Figure 3 and Figure 4As shown, one end of the air motor housing 1 is fixedly connected to a mechanism protection shell 6, and a packaged lubricating mechanism 5 is arranged inside the mechanism protection shell 6. The packaged lubricating mechanism 5 includes a main sleeve 501, and the main sleeve 501 is sleeved on the motor output shaft 204. A toggle plate 502 is rotatably connected to the main sleeve 501, and two symmetrically arranged connecting rods 503 are fixedly connected to the toggle plate 502. The two connecting rods 503 are fixedly connected to closed baffles 504, and the two closed baffles 504 are penetrated. The connecting base 205 is slidably connected to the connecting base 205, and the outer surfaces of the two closed baffles 504 are slidably connected with the connecting tube 505. The two connecting tubes 505 are fixed on the connecting base 205. The two connecting rods 503 are slidably connected to the two connecting tubes 505 respectively. Pulling the toggle plate 502 drives the two closed baffles 504 to be inserted into the air inlet and the air outlet of the connecting base 205 respectively, so as to close the connecting base 205 and prevent dust and water vapor from entering the inside of the pneumatic motor body casing 1.

[0030] The main sleeve 501 is circumferentially fixedly connected with a docking ring gear 509, and the motor output shaft 204 is circumferentially fixedly connected with a docking ring gear 510 adapted to the docking ring gear 509. The main sleeve 501 is circumferentially sleeved with a rotating tube 512. The main sleeve 501 is circumferentially fixedly connected with three limit bars 516. The three limit bars 516 are all slidably connected to the rotating tube 512. The rotating tube 512 is circumferentially fixedly connected with a bevel gear 513 and a driving gear 517. The rotating tube 512 is circumferentially rotatably connected with a limit fixing plate 511. The limit fixing plate 511 is fixedly connected to the inner wall of the mechanism protection shell 6. A rotating rod 515 is rotatably installed on the limit fixing plate 511. The bottom end of the rotating rod 515 is fixed. It is connected to bevel gear 2 514, which meshes with bevel gear 1 513. After the toggle plate 502 toggles the main sleeve 501 to make the docking ring gear 1 509 close to the docking ring gear 2 510, the docking ring gear 1 509 and the docking ring gear 2 510 mesh. The rotation of the docking ring gear 1 509 will drive the motor output shaft 204 to rotate through the docking ring gear 2 510. After the docking ring gear 1 509 and the docking ring gear 2 510 mesh, the rotating rod 515 will drive the rotating tube 512 to rotate through the meshing of bevel gear 2 514 and bevel gear 1 513. The rotation of the rotating tube 512 drives the main sleeve 501 to rotate through the three limit bars 516. The rotation of the main sleeve 501 then drives the docking ring gear 1 509 to rotate.

[0031] like Figure 5 , Figure 6 and Figure 7As shown, a reciprocating threaded rod 519 is arranged inside the mechanism protection shell 6, and the reciprocating threaded rod 519 is rotatably connected to the inner wall of the mechanism protection shell 6, and one end of the reciprocating threaded rod 519 is fixedly connected to a driven gear 518, and the driven gear 518 is meshed with the driving gear 517. A threaded linkage tube 521 is threadedly connected to the reciprocating threaded rod 519, and an L-shaped rod 522 is fixedly connected to the outer wall of the threaded linkage tube 521, and a piston 523 is fixedly connected to the other end of the L-shaped rod 522. When the rotating tube 512 rotates, the driven gear 518 will be driven to rotate through the driving gear 517, and the driven gear 518 will rotate to rotate the reciprocating threaded rod 519. The rotation of the reciprocating threaded rod 519 will drive the threaded linkage tube 521 to move back and forth, and the threaded linkage tube 521 will drive the piston 523 to push and pull back and forth.

The movement of the piston 523 squeezes the internal gas of the cylinder 524 into the storage tube 525, and squeezes the lubricating oil in the storage tube 525. At this time, the lubricating oil will be squeezed into the ejection pipe 526 and atomized from the atomizing head 528 to the inside of the air motor body casing 1. Through the setting of the valve 527, when the device is working, in order to prevent the gas in the air motor body casing 1 from entering the storage tube 525 through the ejection pipe 526, the valve 527 is closed for blocking.

By setting the telescopic spring 6 532, the engaging tongue 2 530 is lifted upward by the spring pressure of the telescopic spring 6 532, so that the engaging tongue 1 529 and the engaging tongue 2 530 are maintained in the engaged state, and when the connecting ring tooth 1 509 and the connecting ring tooth 2 510 need to be cancelled, When the ring tooth 1 509 is meshed with the docking ring tooth 2 510, the pressing rod 533 is pressed to move the locking tongue 2 530 downward, and the locking tongue 2 530 and the locking tongue 1 529 are cancelled. The docking ring tooth 1 509 will be reset by the spring pressure of the telescopic spring 5 508, so that the docking ring tooth 1 509 moves away from the docking ring tooth 2 510. Therefore, when the device is in daily operation, the components of the encapsulated lubrication mechanism 5 will not operate following the rotation of the motor output shaft 204.

[0034] The implementation principle of a novel pneumatic motor in the embodiment of the present application is: When the device needs to be stored, the toggle plate 502 is pulled to drive the two closed baffles 504 to be inserted into the air inlet and outlet of the connecting base 205 respectively, and the connecting base 205 is sealed to prevent dust and water vapor from entering the interior of the pneumatic motor body shell 1. At the same time, the toggle plate 502 will pull the docking ring gear 1 509 on the main sleeve 501 to engage with the docking ring gear 2 510. The staff rotates the rotating rod 515 to drive the rotating tube 512 to rotate through the bevel gear 2 514 and the bevel gear 1 513. The rotation of the rotating tube 512 drives the main sleeve 501 to rotate through the three limit bars 516. The rotation of the main sleeve 501 will drive the motor output shaft 204 to rotate through the docking ring gear 1 509 and the docking ring gear 2 510. The rotation of the motor output shaft 204 causes the five force-bearing push plates 202 on the rotating eccentric roller 201 to rotate. At the same time, the valve 527 is opened to connect the spray pipe 526 with the atomizing head 528. The gear 1 513 rotates through the rotating tube 512 to drive the driving gear 517 to rotate. The driving gear 517 rotates through the driven gear 518 to drive the reciprocating threaded rod 519 to rotate so that the threaded linkage tube 521 moves back and forth. The threaded linkage tube 521 pushes and pulls the piston 523 back and forth through the L-shaped rod 522. The movement of the piston 523 squeezes the internal gas of the cylinder 524 into the storage tube 525, and squeezes the lubricating oil in the storage tube 525. At this time, the lubricating oil will be squeezed into the ejection pipe 526 and sprayed from the atomizing head 528 to the inside of the air motor body shell 1. The five force-bearing push plates 202 on the rotating eccentric roller 201 continue to rotate, so that the atomized lubricating oil is evenly smeared on the inner wall of the air motor body shell 1 and the gap in the shaft body, so that the parts inside the air motor body shell 1 are fully covered with oil film, effectively avoiding the problem of rust inside the air motor after long-term storage. The trachea is inserted into the plug-in sleeve 401 and plugged into the conical anti-skid tube seat 405, and the handle 411 is controlled to drive the inverted conical extrusion block 402 to move downward, so that the inverted conical extrusion block 402 cooperates with the conical anti-skid tube seat 405 to clamp and fix the trachea on the conical anti-skid tube seat 405. Due to the meshing of the pawl 407 and the ratchet bar 409, the pawl 407 will be blocked by the teeth of the ratchet bar 409, thereby preventing the movable sleeve 406 from moving upward, thereby maintaining the connection between the conical anti-skid tube seat 405 and the trachea, and at the same time, the one-way threaded rod 413 is rotated to drive the arc-shaped anti-sliding block 412 to approach the trachea, so that the two arc-shaped anti-sliding blocks 412 clamp and fix the trachea on the conical anti-skid tube seat 405, and prevent the trachea from falling out of the conical anti-skid tube seat 405. The device effectively avoids the problem that the conventional spring lock structure is easy to puncture the trachea and cause air leakage; When replacing the muffler 301, it is only necessary to pull the lifting handle block 309 upward to separate the two limiting wedge blocks 305 from each other, cancel the limiting effect on the muffler 301, and then the muffler 301 can be directly taken out. When installing a new muffler 301, it is only necessary to insert the muffler 301 into the connecting pipe 302, and the muffler 301 will squeeze the two limiting wedge blocks 305 to separate from each other. After the card slot of the muffler 301 moves to the position corresponding to the limiting wedge block 305, the limiting wedge block 305 will be reset by the spring pressure of the second telescopic spring 306, and the two limiting wedge blocks 305 pop out and engage with the muffler 301, completing the installation of the muffler 301. It is very convenient and quick, and effectively avoids the problem of thread wear in the threaded connection method causing the muffler 301 to be difficult to install.

[0035] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
