Description

Technical Field

[0001] The invention belongs to the technical field of fan casing processing, and in particular relates to a centrifugal fan casing finishing device. Background Art

[0002] A centrifugal fan is a machine that relies on input mechanical energy to increase other pressures and deliver gas. It is often used for ventilation, dust removal, cooling, etc. During the processing of centrifugal fans, grinding equipment is needed to fine-process the centrifugal fan casing.

[0003] The Chinese invention patent with the publication number "CN113523964A" discloses a centrifugal fan housing finishing device and finishing process. The centrifugal fan housing is fixed and clamped by a slidable clamping method, and the position of the centrifugal fan is adjusted by an internal support positioning method, so that the axis position of the centrifugal fan housing corresponds to the rotation axis, thereby solving the problem that the centrifugal fan is difficult to effectively position and clamp from the outside and difficult to effectively support and position the centrifugal fan during the finishing process; the present invention completes multiple steps in the prior art at the same time through an adjustable grinding execution end and a simultaneous grinding of the side wall and the end face, thereby reducing the working time of the centrifugal fan housing finishing.

In the above application, the centrifugal fan casing is fixed by a positioning and clamping mode from the inside of the centrifuge, and the centrifugal fan casing is clamped by a spring clamping method from the outside. However, when the centrifugal fan casing is large, the spring will move with a larger amplitude, and when the spring is compressed, its thrust will increase, which may cause the pressure on the centrifugal fan casing to increase, thereby causing damage to the centrifugal fan casing.

DETAILED DESCRIPTION

[0018] 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.

[0019] like Figures 1 to 7 As shown, an embodiment of the present invention provides a centrifugal fan housing finishing device, comprising: A support frame 1, wherein a moving mechanism 2 is disposed in the inner cavity of the support frame 1, a clamping mechanism 3 is disposed inside the moving mechanism 2, the clamping mechanism 3 comprises a piston cylinder 31, the piston cylinder 31 is fixedly connected in the moving mechanism 2, a piston plate 33 is movably sleeved on one side of the inner cavity of the piston cylinder 31 near the center of the moving mechanism 2, a clamping rod 34 is fixedly connected on one side of the piston plate 33 near the center of the moving mechanism 2, and an anti-slip rod 32 is fixedly connected on one side of the clamping rod 34 near the center of the moving mechanism 2; A pressure regulating mechanism 4 is provided on the side of the piston cylinder 31 away from the clamping rod 34, and the pressure regulating mechanism 4 includes an air cylinder 41, which is fixedly connected to the side of the piston cylinder 31 away from the clamping rod 34, and a spring 42 is fixedly connected to the side of the inner cavity of the air cylinder 41 away from the piston cylinder 31, and a gas blocking plate 43 is fixedly connected to the side of the spring 42 close to the piston cylinder 31, and a moving rod 44 is fixedly connected to the center of the side of the gas blocking plate 43 away from the piston cylinder 31, and an exhaust pipe 45 is fixedly sleeved in the middle of the air cylinder 41, and an air collecting bin 46 is fixedly connected to the bottom end of the exhaust pipe 45, and the inner cavity of the air collecting bin 46 is movably sleeved with an air pushing plate 47, and a movable rod 48 is fixedly connected to the side of the air pushing plate 47 away from the center of the moving mechanism 2, and the side of the air collecting bin 46 away from the piston cylinder 31 is sleeved with the movable rod 48.

[0020] The moving mechanism 2 includes a moving plate 22, which is located at the top of the support frame 1. A servo motor 23 is fixedly connected to the outer side of the moving plate 22. The output shaft of the servo motor 23 is fixedly sleeved with a bidirectional threaded rod 24. The bidirectional threaded rod 24 is movably connected to the inner cavity of the moving plate 22. A moving ring 25 is meshed on the surface of the bidirectional threaded rod 24. The top of the moving ring 25 is fixedly connected to a support seat 26. The top of the support seat 26 on one side close to the center of the moving plate 22 is an inclined surface, and the support seat 26 is fixedly connected to the piston cylinder 31.

[0021] A processing mechanism 6 is disposed at the top of the support frame 1 . The moving mechanism 2 further includes a linear motor 21 . The linear motor 21 is fixedly connected to the inner cavity of the support frame 1 . The moving plate 22 is disposed above the linear motor 21 .

[0022] A plurality of clamping rods 34 are provided, and the plurality of clamping rods 34 are all located above the movable plate 22 . The anti-slip rod 32 is semicircular.

[0023] The moving rod 44 is located at the center of the inner cavity of the spring 42 , and the moving rod 44 is movably sleeved at the center of the air pressure cylinder 41 .

[0024] The air blocking plate 43 is attached to the inner wall of the air pressure cylinder 41, the piston cylinder 31 and the inner cavity of the air pressure cylinder 41 are connected, and the air blocking plate 43 is located at the connection between the piston cylinder 31 and the air pressure cylinder 41; In this embodiment, in the initial state, the side surface of the pressing plate 55 is in contact with the moving rod 44 and the movable rod 48 respectively. When the moving rod 44 and the movable rod 48 are pressed, the air pressure in the inner cavity of the piston cylinder 31 and the air cylinder 41 is in a normal state and is consistent with the standard atmospheric pressure. When the device is in use, the centrifugal fan housing is placed on the top of the moving plate 22, and then the servo motor 23 is started to drive the bidirectional threaded rod 24 to rotate, thereby driving the moving ring 25 engaged therewith to move along the axis direction of the bidirectional threaded rod 24 toward the center of the bidirectional threaded rod 24, thereby driving the support seat 26 to move toward the center of the moving plate 22, at which time the moving rod 44 and the movable rod 48 respectively leave the side of the pressing plate 55 and no longer contact each other; Subsequently, the support seat 26 drives the clamping rod 34 to contact the centrifugal fan housing. When the clamping rod 34 drives the anti-slip rod 32 to contact and clamp the concave and convex surfaces of the centrifugal fan housing, the reaction force of the centrifugal fan housing pushes the anti-slip rod 32 and the clamping rod 34, thereby driving the piston plate 33 to move in the inner cavity of the piston cylinder 31 toward the direction of the air pressure cylinder 41. At this time, the air pressure in the inner cavity of the piston cylinder 31 close to the side of the air pressure cylinder 41 is compressed, and then the thrust of the air pressure in the inner cavity of the piston cylinder 31 close to the side of the air pressure cylinder 41 applies pressure to the clamping rod 34, so that the anti-slip rod 32 clamps the centrifugal fan housing strongly, and multiple clamping rods 34 drive the anti-slip rod 32 to move to different positions, and fit tightly to the surface of the centrifugal fan housing, clamp fan housings of different shapes, and jam them. When the piston plate 33 moves toward the air cylinder 41, the external air is sucked into the inner cavity of the piston cylinder 31 near the one-way air intake valve 51 through the one-way air intake valve 51; When the specifications of the centrifugal fan housing or the protrusion of the protruding surface are large, the clamping rod 34 drives the piston plate 33 to move a long distance in the inner cavity of the piston cylinder 31. At this time, the more gas gathers in the inner cavity of the piston cylinder 31 close to the side of the air pressure cylinder 41, the greater the air pressure, which increases the thrust on the clamping rod 34. At this time, the air pressure in the inner cavity of the piston cylinder 31 drives the air blocking plate 43 to move in the direction of the moving rod 44 and cross the exhaust pipe 45, so that part of the air in the inner cavity of the piston cylinder 31 close to the side of the air pressure cylinder 41 is discharged from the exhaust pipe 45 to the air collecting bin 4 6 is temporarily stored, and after the air enters the air collecting chamber 46, it pushes the air pushing plate 47 and the movable rod 48 in the direction of the pressing plate 55, thereby reducing the air pressure of the piston cylinder 31 to a level that is insufficient to push the air blocking plate 43 to move. At this time, the air blocking plate 43 is driven by the spring 42 to reset and block the inner cavity of the piston cylinder 31 again. However, at this time, the air pressure on the side of the piston plate 33 close to the air pressure cylinder 41 is still greater than the atmospheric pressure, thereby avoiding the situation where the centrifugal fan housing is damaged due to the large clamping force on some specifications or when the protruding amplitude of the protruding surface is large; Then, the position of the centrifugal fan housing is adjusted through the displacement of the processing mechanism 6 itself and the movement of the moving plate 22, so that the processing mechanism 6 grinds and processes the upper part of the centrifugal fan housing.

[0025] Embodiment 2: Figures 1 to 7 As shown, an embodiment of the present invention provides a centrifugal fan casing finishing equipment, including a cleaning mechanism 5 arranged on the outer side of the piston cylinder 31, the cleaning mechanism 5 includes a one-way air inlet valve 51, the one-way air inlet valve 51 is fixedly connected to the side of the piston cylinder 31 away from the air pressure cylinder 41, the top of the piston cylinder 31 is fixedly connected to the side of the air pressure cylinder 41, the bottom of the air outlet pipe 52 is fixedly connected to a one-way exhaust valve 53, the top of the air outlet pipe 52 is fixedly connected to a dust blowing row 54, and pressing plates 55 are fixedly installed on both sides of the top of the movable plate 22 close to the movable mechanism 2.

[0026] The pressing plate 55 is located on the moving paths of the moving rod 44 and the active rod 48 , and the inner cavity of the air cylinder 41 is connected to the outside through the exhaust pipe 45 .

[0027] The dust blowing row 54 is located above the support seat 26 . The dust blowing row 54 is an inclined hollow cavity. The air outlet of the dust blowing row 54 is opened on one side of the dust blowing row 54 close to the center of the moving plate 22 .

[0028] The support seat 26 is reset by rotating the two-way threaded rod 24, and the movable rod 44 and the movable rod 48 are brought into contact with the pressing plate 55 as the support seat 26 is reset. The movable rod 44 and the movable rod 48 can be pushed up by the pressing plate 55 through the continuous movement of the support seat 26. The movable rod 44 drives the air blocking plate 43 to cross the connection position between the piston cylinder 31 and the air pressure cylinder 41 and enter the inner cavity of the piston cylinder 31. At this time, the inner cavity of the piston cylinder 31 and the air pressure cylinder 41 are connected. When the movable rod 48 moves, it drives the push plate 47 to move in the inner cavity of the air collecting bin 46 (the push plate 47 slides to the end of the air collecting bin 46 away from the piston cylinder 31 before), and pushes the air in the inner cavity of the air collecting bin 46 from the exhaust pipe 45 into the inner cavity of the piston cylinder 31. At this time, the piston plate 33 is reset by the gas returning to the inner cavity of the piston cylinder 31. When the piston plate 33 is reset, the air in the inner cavity of the piston cylinder 31 near the one-way air inlet valve 51 is discharged from the air outlet pipe 52, and then blown out to the top of the support seat 26 through the dust blowing exhaust 54, and then blown to the surface of the anti-slip rod 32 and the clamping rod 34 along the inclination angle of the support seat 26, and then the debris above the support seat 26, the anti-slip rod 32 and the clamping rod 34 is blown away, thereby realizing automatic removal of debris during reset, preventing debris from entering the piston cylinder 31 along the clamping rod 34 and causing wear of the piston plate 33 in the piston cylinder 31.

[0029] Working principle and use process: Place the centrifugal fan casing on the top of the moving plate 22, then start the servo motor 23 to drive the bidirectional threaded rod 24 to rotate, thereby driving the moving ring 25 meshing therewith to move along the axial direction of the bidirectional threaded rod 24 toward the center of the moving plate 22, thereby driving the support seat 26 to move, thereby driving multiple anti-slip rods 32 to clamp the centrifugal fan casing. When the anti-slip rods 32 clamp the centrifugal fan casing, the clamping rods 34 drive the piston plate 33 to move toward the inside of the piston cylinder 31. At this time, the clamping rods 34 generate thrust through the air pressure on the side of the piston cylinder 31 away from the one-way air intake valve 51, driving multiple independently set clamping rods 34 to be clamped on the concave and convex surfaces of centrifugal fan casings of different specifications; The external air is sucked into the inner cavity of the piston cylinder 31 close to the one-way air intake valve 51 through the one-way air intake valve 51; When the specifications of the centrifugal fan housing or the protrusion of the protruding surface are large, the clamping rod 34 needs to move a long distance when contacting the convex surface. At this time, the air pressure thrust in the inner cavity of the piston cylinder 31 will increase. When the pressure of the piston plate 33 close to the side of the air pressure cylinder 41 reaches a level that can overcome the elastic force of the spring 42, it will drive the air blocking plate 43 to push the spring 42 to move in the inner cavity of the air pressure cylinder 41, so that the air blocking plate 43 passes over the exhaust pipe 45, and then the air in the inner cavity of the piston cylinder 31 is discharged from the exhaust pipe 45 in the inner cavity of the air pressure cylinder 41 to the inner cavity of the air collecting bin 46 for temporary storage, and push the push plate 47 and the movable rod 48 in the direction of the pressing plate 55, so that the piston plate 33 is close to the air pressure cylinder 41. The air pressure on one side decreases. When the air pressure on the side of the piston plate 33 close to the air pressure cylinder 41 is not enough to overcome the elastic force of the spring 42, the higher thrust of the spring 42 drives the air blocking plate 43 to move in the direction of the piston cylinder 31 over the exhaust pipe 45 to block the inner cavity of the piston cylinder 31 again. At this time, the pressure on the side of the piston plate 33 close to the air pressure cylinder 41 is still greater than the atmospheric pressure. The clamping rod 34 can be limited by the piston plate 33 to prevent the piston plate 33 from moving during the subsequent grinding and finishing process. At this time, the thrust exerted on the piston plate 33 by the pressure on the side of the piston plate 33 close to the air pressure cylinder 41 is not enough to cause damage to the centrifugal fan casing through the clamping rod 34 and the anti-slip rod 32. Then, the processing mechanism 6 is used to grind and finish the centrifugal fan housing. The processing mechanism 6 moves itself in combination with the linear motor 21 to drive the moving plate 22 to move, so that the processing mechanism 6 grinds and finishes the centrifugal fan housing. After the processing is completed, the servo motor 23 is started to drive the bidirectional threaded rod 24 to rotate, and the support seat 26 is driven to reset. At this time, since the air pressure in the inner cavity of the piston cylinder 31 is adjusted, after the clamping rod 34 leaves the centrifugal fan housing, the air pressure in the inner cavity of the piston cylinder 31 is relatively small, and the piston plate 33 cannot be driven to reset. Therefore, the multiple clamping rods 34 are still located at the position after clamping the centrifugal fan housing. As the support seat 26 is reset, the moving rod 44 and the movable rod 48 are driven to contact the pressing plate 55. Then, through the continuous movement of the support seat 26, the moving rod 44 and the movable rod 48 are pushed toward the direction of the moving plate 22 through the pressing plate 55. The moving rod 44 drives the air blocking plate 43 to enter the inner cavity of the piston cylinder 31. At this time, the inner cavity of the piston cylinder 31 and the inner cavity of the air pressure cylinder 41 are connected. At the same time, when the movable rod 48 moves, it drives the air pushing plate 47 to move in the inner cavity of the air collecting bin 46, and pushes the air in the inner cavity of the air collecting bin 46 from the exhaust pipe 45 into the inner cavity of the piston cylinder 31. At this time, the piston plate 33 is reset by the gas returning to the inner cavity of the piston cylinder 31. When the piston plate 33 is reset, the air in the inner cavity of the piston cylinder 31 near the one-way air inlet valve 51 is discharged from the air outlet pipe 52, and then blown out to the clamping rod 34 through the dust blowing exhaust 54, so as to prevent the clamping rod 34 from entering the piston cylinder 31 and causing the piston plate 33 in the piston cylinder 31 to wear.
