[0022] 1.

[0023] 2. When the present invention is working, the gear cylinder drives the transmission gear ring to rotate at a constant speed. During the constant speed rotation of the transmission gear ring, the transmission bevel gear ring and the driven bevel gear are set to drive the gear shaft to rotate. After the gear shaft rotates, the transmission connection setting between the first half-missing gear and the reciprocating gear plate drives the inner vibration ring and the outer vibration frame to move back and forth within the set stroke. After the inner vibration ring and the outer vibration frame move back and forth within the set stroke, the turbine blade body is then put into a vibration cleaning state during cleaning. By achieving the vibration cleaning effect, the cleaning efficiency of the turbine blade body is effectively improved and self-shaking of the turbine blade body during cleaning is achieved. When the turbine blade body is cleaned, and the turbine blade body is removed from the cleaning cylinder, The turbine blade body continues to rotate. After the turbine blade body rotates, it is centrifugally de-liquidated and centrifugally discarded after cleaning. The brushed-out cleaning liquid flows back to the cleaning cylinder. During the paint dipping operation, the turbine blade body vibrates at a set frequency in the paint dipping cylinder. The vibration of the turbine blade body is used to effectively improve the immersion efficiency and paint uniformity of the turbine blade body. After the turbine blade body is painted in the paint dipping cylinder for a specified time, the turbine blade body is removed from the paint dipping cylinder under the driving action of the lifting frame. After the turbine blade body is removed from the paint dipping cylinder, the turbine blade body continues to rotate and shake. The rotation and shaking of the turbine blade body are used to achieve vibration shaking off of excess paint on the turbine blade body.

[0024] 3. In the present invention, when the processing positions of the turbine blade body and the cleaning cylinder and the paint dipping cylinder are misaligned, the stirring shaft and the rotary suction seat are automatically reset under the action of the coil spring, thereby facilitating the accurate loading and unloading of the turbine blade body. After the rotary suction seat absorbs the turbine blade body by the loading mechanism, the negative pressure vacuum cleaner performs negative pressure vacuuming on the turbine blade body. When the turbine blade body is in the cleaning cylinder for cleaning, the air cleaning pump sends a high-pressure air cleaning flow into the cleaning liquid. The introduction of the high-pressure air cleaning flow improves the decontamination efficiency of the turbine blade body. When the turbine blade body is finished with paint dipping and has been removed from the paint dipping cylinder for a specified time, the hot air blower discharges hot air, thereby realizing thermal drying and heat setting of the paint on the surface of the turbine blade body.

DETAILED DESCRIPTION

[0036] 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.

[0037] See also Figure 1-10 , an ultra-high pressure steam turbine blade processing device, comprising a frame 1, and further comprising:

[0039] Two symmetrically arranged connection blocks 15 are installed on the turbine blade body 2, and connection screw holes are fixedly opened on the connection blocks 15. Positioning columns 45 matching the connection screw holes are equidistantly installed on the annular conveyor belt 12. The turbine blade body 2 is made of iron.

[0040] By setting the positioning column 45, the placement angle of the turbine blade body 2 on the annular conveyor belt 12 is effectively limited;

[0041] The loading mechanism and the unloading mechanism both include two annular conveyor belts 12 and a conveyor frame 13 fixed on the frame 1. The inner wall of the conveyor frame 13 is rotatably connected to two conveyor rollers. Both conveyor rollers are drivingly connected to the annular conveyor belt 12. A conveyor motor is installed on the side of the conveyor frame 13. The output shaft end of the conveyor motor is fixedly connected to a conveyor roller. A retaining frame 14 for limiting the moving position of the turbine blade body 2 is fixedly installed on the conveyor frame 13.

[0042] When the steam turbine blade body 2 is processed, the processed steam turbine blade body 2 is regularly stacked between two annular conveyor belts 12 in the feeding mechanism;

[0043] The steam turbine blade bodies 2 after processing are regularly stacked between two annular conveyor belts 12 in the unloading mechanism;

[0044] The annular conveyor belt 12 cooperates with the connecting block 15 on the turbine blade body 2 and carries out position limiting for the turbine blade body 2;

[0045] The screw lifting module 44 is installed on the frame 1, and the frame 1 is transmission-connected with the lifting frame 3;

[0046] The transmission component is installed on the lifting frame 3, and the transmission component includes an inner vibration ring 4, an outer vibration frame 5, a transmission gear ring 6 and a transfer frame 7. The inner vibration ring 4 is rotatably connected with the outer vibration frame 5;

[0047] The transmission gear ring 6 is rotatably sleeved on the transfer frame 7;

[0048] The transmission component includes a first motor 17 and a second motor 18 fixed on the lifting frame 3. A reciprocating tooth plate 16 is fixedly installed on the top surface of the inner vibration ring 4. A gear cylinder 19 is rotatably connected to the lifting frame 3. The gear cylinder 19 is driven by the first motor 17.

[0049] See also Figure 1 The first motor 17 is connected to the gear cylinder 19 through a belt, and a pulley is fixedly mounted on the gear cylinder 19;

[0050] The gear cylinder 19 is fixedly connected to the transmission gear ring 6, the indexing frame 7 is rotatably connected to the gear cylinder 19, and the output shaft end of the second motor 18 is transmission-connected to the indexing frame 7 through a chain belt;

[0051] The rotatable structure of the transfer frame 7 can quickly change the layout positions of the four rotating processing parts;

[0052] When working, the processing device is equipped with four workstations, namely, the loading station, the cleaning station, the varnishing station and the unloading station;

[0053] The loading station, cleaning station, varnishing station and unloading station are arranged in a clockwise direction;

[0054] The cleaning cylinder 8 is arranged on the cleaning station, and the paint dipping cylinder 9 is arranged on the paint dipping station;

[0055] The upper part of the lifting frame 3 is rotatably connected with a gear shaft 20, on which a first half-missing gear 21 is mounted, the first half-missing gear 21 is transmission-connected to the reciprocating gear plate 16, and the gear shaft 20 is driven to rotate through the gear cylinder 19;

[0056] During operation, the gear cylinder 19 drives the transmission gear ring 6 to rotate at a constant speed. During the constant speed rotation of the transmission gear ring 6, the transmission bevel gear ring and the driven bevel gear are set to drive the gear shaft 20 to rotate. After the gear shaft 20 rotates, when the first half-missing gear 21 is in transmission meshing with the reciprocating gear plate 16, the inner vibration ring 4 and the outer vibration frame 5 move down synchronously. When the first half-missing gear 21 is not in transmission meshing with the reciprocating gear plate 16, under the action of the reset spring 29, the inner vibration ring 4 and the outer vibration frame 5 move up and reset synchronously. Through the continuous rotation of the first half-missing gear 21, the inner vibration ring 4 and the outer vibration frame 5 are moved back and forth within the set stroke. After the inner vibration ring 4 and the outer vibration frame 5 are moved back and forth within the set stroke, the turbine blade body 2 is in a vibration cleaning state during cleaning. Through the realization of the vibration cleaning effect, the cleaning efficiency of the turbine blade body 2 is effectively improved and the self-shaking of the turbine blade body 2 during cleaning is realized.

[0057] After the steam turbine blade body 2 is cleaned and removed from the cleaning cylinder 8, the steam turbine blade body 2 continues to rotate. After the steam turbine blade body 2 rotates, centrifugal liquid removal and centrifugal liquid removal are performed after cleaning, and the brushed cleaning liquid flows back to the cleaning cylinder 8;

[0058] During the varnishing operation, the turbine blade body 2 vibrates at a set frequency in the varnishing barrel 9. The vibration of the turbine blade body 2 effectively improves the varnishing efficiency and varnishing uniformity of the turbine blade body 2. After the turbine blade body 2 is varnished in the varnishing barrel 9 for a specified time, the turbine blade body 2 is driven by the lifting frame 3 to escape from the varnishing barrel 9. After the turbine blade body 2 escapes from the varnishing barrel 9, the turbine blade body 2 continues to rotate and shake. The rotation and shaking of the turbine blade body 2 can realize the vibration shaking off of the excess paint on the turbine blade body 2.

[0059] The cleaning cylinder 8 and the paint dipping cylinder 9 are both clamped on the frame 1, and the positions on the inner vibration ring 4 and directly above the cleaning cylinder 8 and the paint dipping cylinder 9 are both rotatably connected with a coupling shaft 10, and the two coupling shafts 10 are both fixedly installed with a linkage gear 11 that is transmission-connected to the transmission gear ring 6;

[0060] When the steam turbine blade body 2 is in the processing position of the cleaning cylinder 8 and the paint dipping cylinder 9, the steam turbine blade body 2 is driven to rotate. When the steam turbine blade body 2 is misaligned with the cleaning cylinder 8 and the paint dipping cylinder 9, the steam turbine blade body 2 is guaranteed to be stationary.

[0061] Four rotary processing components distributed in a circular array are installed on the external vibration frame 5;

[0062] The rotary processing component includes an outer rotary sleeve 22 rotatably connected to the outer vibration frame 5, the inner wall of the outer rotary sleeve 22 is rotatably connected to the inner shaft 23, and a reciprocating linkage is installed on the outer vibration frame 5;

[0063] The outer rotating sleeve 22 and the inner rotating shaft 23 are driven by a reciprocating linkage and reciprocate within a set period;

[0064] The reciprocating linkage comprises a reciprocating shaft 30 rotatably connected to the outer oscillating frame 5 and a second half-missing gear 31 fixed to the inner rotating shaft 23. The second half-missing gear 31 is transmission-connected to the transmission gear ring 6. A disc spring 32 is fixedly arranged at the rotation connection between the reciprocating shaft 30 and the outer oscillating frame 5. The outer rotating sleeve 22 and the inner rotating shaft 23 are both driven by the reciprocating shaft 30.

[0065] Please see attached Figure 5 The outer rotating sleeve 22 and the inner rotating shaft 23 are both fixedly mounted with external bevel gears.

[0066] During operation, external bevel gears (external bevel gear A and external bevel gear B, respectively) are fixedly mounted on the external rotating sleeve 22 and the internal rotating shaft 23, and the external bevel gear A is located at one end of the external rotating sleeve 22, and the external bevel gear B is located at one end of the internal rotating shaft 23 close to the external rotating sleeve 22. A middle bevel gear is fixedly mounted on the reciprocating shaft 30, and the middle bevel gear is located in the middle of the reciprocating shaft 30, and is located exactly between the external bevel gear A and the external bevel gear B. With this arrangement, the middle bevel gear can mesh with the two external bevel gears (external bevel gear A and external bevel gear B) for transmission at the same time.

[0067] Specifically, when the reciprocating shaft 30 rotates, the middle bevel gear fixed thereon will drive the outer bevel gear A on the outer rotating sleeve 22 to rotate, and then transmit the rotational force to the outer bevel gear B on the inner rotating shaft 23 through the connecting structure between the outer rotating sleeve 22 and the inner rotating shaft 23 (such as bearings, etc., which are not described in detail here), thereby realizing the rotation of the outer rotating sleeve 22 and the inner rotating shaft 23.

[0068] A middle bevel gear is fixedly mounted on the reciprocating shaft 30, and the two outer bevel gears are both transmission-connected to the middle bevel gear, and the middle bevel gear is arranged between the two outer bevel gears;

[0069] The tooth heights of the linkage gear 11 and the second half-missing gear 31 are the same, and the tooth height of the transmission gear ring 6 is 10 times the tooth height of the linkage gear 11;

[0070] An active gear ring 24 is fixedly mounted on the outer rotating sleeve 22, a rotary suction seat 25 is fixedly mounted on the bottom end of the inner rotating shaft 23, an electromagnet is built inside the rotary suction seat 25, a group of stirring shafts 26 are rotatably connected to the rotary suction seat 25, an upper gear 27 is fixedly mounted on the stirring shaft 26, the upper gear 27 is transmission-connected to the active gear ring 24, two stirring rods 28 are mounted on the stirring shaft 26, and a reset spring 29 is sleeved on the outer rotating sleeve 22 and corresponds to the position between the outer vibration frame 5 and the indexing frame 7.

[0071] After the steam turbine blade body 2 is magnetically attracted and positioned by the electromagnet, the steam turbine blade body 2 rotates at a set speed during the cleaning and varnishing process. When the steam turbine blade body 2 rotates, the stirring shaft 26 rotates at a set speed under the driving action of the active gear ring 24, and then the cleaning intensity and varnishing efficiency of the steam turbine blade body 2 are improved through auxiliary stirring.

[0072] When the turbine blade body 2 is misaligned with the processing positions of the cleaning cylinder 8 and the paint dipping cylinder 9, the stirring shaft 26 and the rotary suction seat 25 are automatically reset under the action of the coil spring 32, thereby facilitating the accurate loading and unloading of the turbine blade body 2;

[0073] The gas-assisted component is used to deliver negative pressure, high-pressure clean air and hot drying air to the four spin-load processing components in a directional manner.

[0074] The gas-assisted component includes an air inlet assembly that cooperates with the stirring shaft 26 and an inner frame 33 fixed on the lifting frame 3. An air distributor 34 is installed at the bottom end of the inner frame 33. Four mutually isolated air guide cavities 35 are opened inside the air distributor 34. Air holes 36 are opened inside the air distributor 34 and at positions corresponding to the four air guide cavities 35. An inner rotating ring 37 is rotatably connected on the air distributor 34 and at positions corresponding to the outer sides of the air holes 36. A negative pressure vacuum cleaner 38, an air cleaning pump 39 and a hot air blower 40 are respectively installed on the inner frame 33. The suction end of the negative pressure vacuum cleaner 38, the air outlet end of the air cleaning pump 39 and the air outlet end of the hot air blower 40 are respectively connected to an air guide cavity 35.

[0075] The air inlet assembly includes an outer rotating ring 41, an air dividing ring 42 and an air inlet passage opened on the stirring shaft 26. The top of the air inlet passage is rotationally connected to the inner cavity of the air dividing ring 42. The outer rotating ring 41 is rotationally connected to the air dividing ring 42. A hose is connected between the outer rotating ring 41 and the inner rotating ring 37. A group of regularly distributed air inlet strip holes 43 connected to the air inlet passage are opened on the stirring shaft 26.

[0076] The position of the negative pressure vacuum cleaner 38 corresponds to the position of the feeding mechanism, the position of the air cleaning pump 39 corresponds to the position of the cleaning cylinder 8, and the position of the hot air blower 40 corresponds to the position of the paint dipping cylinder 9.

[0077] After the rotary suction seat 25 sucks the turbine blade body 2 by the feeding mechanism, the negative pressure vacuum cleaner 38 performs negative pressure vacuuming on the turbine blade body 2. When the turbine blade body 2 is cleaned in the cleaning cylinder 8, the air cleaning pump 39 sends a high-pressure air cleaning flow into the cleaning liquid. The introduction of the high-pressure air cleaning flow improves the decontamination efficiency of the turbine blade body 2. When the turbine blade body 2 is painted and has been removed from the paint dipping cylinder 9 for a specified time, the hot air blower 40 discharges hot air, thereby realizing thermal drying and heat setting of the paint on the surface of the turbine blade body 2.

[0078] The working principle of the present invention is as follows: after the rotary suction seat 25 sucks the turbine blade body 2 by the feeding mechanism, the negative pressure vacuum cleaner 38 performs negative pressure vacuuming on the turbine blade body 2. When the turbine blade body 2 is in the cleaning cylinder 8 for cleaning, the air cleaning pump 39 sends a high-pressure air cleaning flow into the cleaning liquid. By sending in the high-pressure air cleaning flow, the decontamination efficiency of the turbine blade body 2 is improved. When the turbine blade body 2 is finished being dipped in paint and has been removed from the dip paint cylinder 9 for a specified time, the hot air blower 40 blows out hot air, thereby achieving thermal drying and heat setting of the paint on the surface of the turbine blade body 2. When working, the gear cylinder 19 drives the transmission The movable gear ring 6 rotates at a constant speed. During the constant speed rotation of the transmission gear ring 6, the transmission bevel gear ring and the driven bevel gear are set to drive the gear shaft 20 to rotate. After the gear shaft 20 rotates, the transmission connection setting between the first half-missing gear 21 and the reciprocating gear plate 16 is used to drive the inner vibration ring 4 and the outer vibration frame 5 to move back and forth within the set stroke. After the inner vibration ring 4 and the outer vibration frame 5 move back and forth within the set stroke, the turbine blade body 2 is put into a vibration cleaning state during cleaning. By achieving the vibration cleaning effect, the cleaning efficiency of the turbine blade body 2 is effectively improved and the self-shaking of the turbine blade body 2 during cleaning is achieved.

[0079] Among them, the gear cylinder 19 drives the transmission gear ring 6 to rotate at a constant speed. During the constant speed rotation of the transmission gear ring 6, the gear shaft 20 is driven to rotate through the setting of the transmission bevel gear ring and the driven bevel gear. After the gear shaft 20 rotates, when the first half-missing gear 21 is in transmission engagement with the reciprocating gear plate 16, it will drive the inner vibration ring 4 and the outer vibration frame 5 to move downward to the lowest position; and when the first half-missing gear 21 is not in transmission engagement with the reciprocating gear plate 16, under the action of the reset spring 29, the inner vibration ring 4 and the outer vibration frame 5 will move upward and reset to the initial position. Through the continuous rotation of the first half-missing gear 21, the inner vibration ring 4 and the outer vibration frame 5 are then moved up and down within the set stroke.

[0080] After the cleaning of the steam turbine blade body 2 is completed and the steam turbine blade body 2 is removed from the cleaning cylinder 8, the steam turbine blade body 2 continues to rotate. After the steam turbine blade body 2 rotates, centrifugal dehydration and centrifugal liquid removal are performed after cleaning, and the brushed cleaning liquid flows back to the cleaning cylinder 8. During the varnishing operation, the steam turbine blade body 2 vibrates at a set frequency in the varnishing cylinder 9. The vibration of the steam turbine blade body 2 is used to effectively improve the immersion efficiency and varnishing uniformity of the steam turbine blade body 2. After the steam turbine blade body 2 is varnished in the varnishing cylinder 9 for a specified time, the steam turbine blade body 2 is removed from the varnishing cylinder 9 under the driving action of the lifting frame 3. After the steam turbine blade body 2 is removed from the varnishing cylinder 9, the steam turbine blade body 2 continues to rotate and shake. The rotation and shaking of the steam turbine blade body 2 are used to achieve vibration shaking off of excess paint on the steam turbine blade body 2.

[0081] When the turbine blade body 2 is misaligned with the processing positions of the cleaning cylinder 8 and the paint dipping cylinder 9, the stirring shaft 26 and the rotary suction seat 25 are automatically reset under the action of the disc spring 32, thereby facilitating the accurate loading and unloading of the turbine blade body 2.

[0082] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations may be made to the embodiments without departing from the principles and spirit thereof, and the scope of the present invention is defined by the appended claims and their equivalents.
