When the two long straight parts on the driving frame move to the two rollers, the two rollers drive the two clamping frames to clamp the rudder stock, so that the corrected rudder stock can be clamped to avoid displacement of the rudder stock during processing, thereby further improving the processing accuracy of the rudder stock.

Description

Technical Field

[0001] The invention relates to the field of production and processing of ship rudders, and in particular to a production and processing device for a ship rudder. Background Art

[0002] The rudder stock refers to the axis on which the rudder blade rotates. It is used to bear and transmit the force acting on the rudder blade and the force given by the rudder to the steering device. In other words, the steering gear rotates the rudder blade through the rudder stock, and the rudder blade bears the reaction force of the water to enable the ship to turn.

[0003] In order to install various parts on the rudder stock, it is necessary to process various mounting holes on the rudder stock. During the current processing of the rudder stock, in order to improve the processing accuracy of the rudder stock, the operator needs to adjust the position of the rudder stock many times. At the same time, it is inconvenient to fix the rudder stock. If there are impurities on the rudder stock, it will affect the position of the rudder stock after clamping, thereby reducing the processing accuracy of the rudder stock. Summary of the invention

In this way, the secondary correction of the rudder stock is completed, so that the rudder stock can be corrected more accurately, thereby further improving the processing accuracy of the rudder stock.

[0015] 3. The driving frame drives the piston frame to slide in the square cylinder. The air in the square cylinder is discharged from the porous tube through the exhaust check valve and the hose and blown onto the rudder stock. During the rotation of the rudder stock, the discharged air can completely clean the impurities remaining on the rudder stock, avoiding impurities getting stuck between the clamping frame and the rudder stock when the clamping frame clamps the rudder stock, thereby making the position of the rudder stock more accurate after being fixed, and further improving the processing accuracy of the rudder stock.

It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0031] Embodiment 1: A marine rudder production and processing device, such as Figure 1-Figure 4As shown, it includes a shell 1, a fixed top frame 3, a rudder stock 4, a correction mechanism and a clamping mechanism. A placement groove 2 inclined toward the middle is opened on the upper part of the shell 1, and a fixed top frame 3 is welded to one side of the placement groove 2. The rudder stock 4 is placed in the placement groove 2. A key groove 41 is opened on the side of the rudder stock 4 close to the fixed top frame 3. One end of the rudder stock 4 is in contact with the fixed top frame 3. A correction mechanism is provided on the shell 1, and the correction mechanism is used to correct the rudder stock 4. A clamping mechanism is provided on the shell 1, and the clamping mechanism is used to clamp the rudder stock 4.

[0032] The correction mechanism includes a fixed plate 51, a rotating shaft 52, a motor 53, a threaded rod 54, a sliding plate 55, a nut 56, a sliding top frame 57 and a transverse spring 58. Two fixed plates 51 are installed in the shell 1, and a rotating shaft 52 is rotatably provided between the two fixed plates 51. The end of the rotating shaft 52 away from the fixed top frame 3 is rotatably connected to the side of the shell 1 away from the fixed top frame 3. A motor 53 is installed on the side of the shell 1 close to the fixed top frame 3, and the output shaft of the motor 53 is connected to the end of the rotating shaft 52 close to the fixed top frame 3. A threaded rod 54 is installed on the side of the rotating shaft 52 away from the motor 53, and a sliding plate 55 is slidably installed on the other side of the placement groove 2. A nut 56 is installed at the lower part of the sliding plate 55, and the nut 56 is threadedly connected to the threaded rod 54. A sliding top frame 57 is slidably provided on the upper part of the sliding plate 55, and a transverse spring 58 is provided between the sliding top frame 57 and the sliding plate 55.

[0033] The clamping mechanism includes a clamping frame 61, a roller 62 and a driving frame 63. A clamping frame 61 is slidably provided on both sides of the shell 1. The two clamping frames 61 are symmetrically arranged. The two clamping frames 61 are respectively located on both sides of the rudder bar 4. Rollers 62 are rotatably provided on the two clamping frames 61. The rollers 62 are located in the shell 1. The driving frame 63 is installed on the sliding plate 55. The driving frame 63 consists of two short straight parts, two inclined parts and two long straight parts. The two rollers 62 are respectively located in the two short straight parts of the driving frame 63.

[0034] First, the operator installs the device on the processing machine, and then places the rudder bar 4 on the placement groove 2, and makes one end of the rudder bar 4 contact with the fixed top frame 3. Then the operator starts the motor 53 to rotate, and the motor 53 drives the rotating shaft 52 and the threaded rod 54 to rotate. The rotation of the threaded rod 54 drives the nut 56, the sliding plate 55, the sliding top frame 57 and the cross spring 58 to move in the direction close to the fixed top frame 3. After the sliding top frame 57 contacts the other end of the rudder bar 4, the sliding top frame 57 pushes the rudder bar 4 to move, and the fixed top frame 3 and the sliding top frame 57 are used to control the rudder bar 4. The position is initially corrected so that the rudder bar 4 can be aligned with the main shaft of the processing machine tool, thereby improving the processing accuracy of the rudder bar 4; when the sliding plate 55 continues to move in the direction close to the fixed top frame 3, it drives the driving frame 63 to move, and the sliding top frame 57 is supported by the rudder bar 4, and the sliding top frame 57 no longer moves, and the cross spring 58 is stretched accordingly. When the two inclined parts on the driving frame 63 move to the two rollers 62, the two rollers 62 will move in the direction close to each other, and the two rollers 62 drive the two clamping frames 61 to move in the direction close to each other, and the two rollers 62 on the driving frame 63 When the long straight portion moves to the two rollers 62, the two rollers 62 drive the two clamping frames 61 to clamp the rudder stock 4, so that the corrected rudder stock 4 can be clamped to prevent the rudder stock 4 from being displaced during processing, thereby further improving the processing accuracy of the rudder stock 4; after the rudder stock 4 is processed by the processing machine, the operator starts the motor 53 to rotate in the reverse direction, and the motor 53 drives the rotating shaft 52 and the threaded rod 54 to rotate in the reverse direction, and the threaded rod 54 rotates in the reverse direction to drive the nut 56, the sliding plate 55, the sliding top frame 57 and the cross spring 58 to move away from the fixed top frame 3 The sliding top frame 57 moves in the direction of rotation. After the sliding top frame 57 is separated from the other end of the rudder bar 4, the sliding top frame 57 can be moved and reset under the action of the cross spring 58. When the two inclined parts on the driving frame 63 move to the two rollers 62, the two rollers 62 will move away from each other, and the two rollers 62 drive the two clamping frames 61 to move away from each other. The two clamping frames 61 release the fixation on the rudder bar 4. When the two short straight parts on the driving frame 63 move to the two rollers 62, the operator turns off the motor 53, and the operator takes out the processed rudder bar 4.

[0035] Embodiment 2: Based on embodiment 1, Figure 5-Figure 11As shown, the housing 1 further includes a positioning mechanism, which is arranged on a side of the housing 1 close to the fixed top frame 3. The positioning mechanism is used to correct and position the rudder bar 4. The positioning mechanism includes a guide ring 81, a slider 82, a swivel 83, a positioning rod 84, a vertical spring 85, a horizontal shaft 86, a driven gear 87, a driving gear 88 and a protrusion 89. An opening 801 is opened on the side of the housing 1 close to the fixed top frame 3, and a guide ring 81 is installed on the opening 801. Two sliders 82 are slidably provided on the guide ring 81. The two sliders 82 are symmetrically arranged. A swivel 83 is installed between the two sliders 82 by bolts. The swivel 83 slides on the swivel A positioning rod 84 is dynamically provided, and the positioning rod 84 will slide along the swivel 83. A vertical spring 85 is connected between the positioning rod 84 and the swivel 83, and the vertical spring 85 is wound around the positioning rod 84. One end of the positioning rod 84 is in contact with the rudder bar 4, and a horizontal shaft 86 is rotatably provided on the other end of the positioning rod 84. A driven gear 87 is installed on the swivel 83, and a driving gear 88 is key-connected on the side of the rotating shaft 52 close to the motor 53. The driving gear 88 meshes with the driven gear 87. A protrusion 89 is installed on the side of the opening 801 close to the fixed top frame 3, and the horizontal shaft 86 is in contact with the protrusion 89.

[0036] The positioning rod 84 further includes a positioning bead 841 . The end of the positioning rod 84 away from the horizontal axis 86 is rotatably provided with a positioning bead 841 .

[0037] It also includes an auxiliary mechanism, which is arranged at the top of the shell body 1. The auxiliary mechanism is used to assist the rudder bar 4 in correcting and positioning. Two sliding frames 91 are slidingly arranged at the top of the shell body 1. The two sliding frames 91 are symmetrically arranged. Twenty balls 92 are evenly spaced on the two sliding frames 91. The bottom of the rudder bar 4 contacts with a number of balls 92 on both sides. Grooves 93 are opened on the two clamping frames 61. The lower part of the sliding frame 91 on the same side will be stuck in the two grooves 93 on the clamping frame 61 on the same side.

[0038] Initially, the transverse axis 86 contacts with the protrusion 89, the positioning rod 84, the positioning bead 841 and the transverse axis 86 will move downward, and the vertical spring 85 will be stretched accordingly. The end of the rudder stock 4 with the keyway 41 is placed toward the side close to the opening 801, and the keyway 41 is placed upward. After the rudder stock 4 is placed in the placement slot 2, the side of the rudder stock 4 will contact with the positioning bead 841, and the rotation of the shaft 52 drives the driving gear 88 to rotate, and the driving gear 88 drives the driven gear 87 to rotate, and the driven gear 87 drives the swivel 83 and the slider 82 to rotate along the guide ring 81, and the swivel 83 drives the positioning rod 84, the positioning bead 841, the vertical spring 85 and the transverse axis 86 to rotate along the rudder stock 4, and the positioning bead 841 plays a guiding role. After the transverse axis 86 is separated from the protrusion 89, due to the gravity of the rudder stock 4 itself, the positioning rod 84, the positioning bead 841, the vertical spring 85 and the transverse axis 86 will not move. When the positioning bead 841 moves to the keyway 41, under the action of the vertical spring 85, the positioning rod 84, the positioning bead 841 and the transverse axis 86 will move, and the positioning rod 84 and the positioning bead 841 are inserted into the keyway 41. The positioning rod 84 and the positioning bead 841 drive the rudder bar 4 to rotate through the keyway 41. After the transverse axis 86 rotates to contact with the protrusion 89, the positioning rod 84, the positioning bead 841 and the transverse axis 86 will move downward, and the vertical spring 85 will be stretched accordingly, and the positioning rod 84 and the positioning bead 841 will be separated from the keyway 41. In this way, the secondary correction of the rudder bar 4 is completed, so that the rudder bar 4 can be corrected more accurately, thereby further improving the processing accuracy of the rudder bar 4. During the secondary correction of the rudder bar 4, the roller 62 moves in the two short straight parts of the driving frame 63.

[0039] Initially, the sliding frame 91 is supported by the clamping frame 61, and the rudder bar 4 contacts with the ball bearings 92 on both sides. During the secondary correction of the rudder bar 4, the ball bearings 92 guide the rudder bar 4, and the rudder bar 4 can move more smoothly. The two clamping frames 61 move in the direction of approaching each other, driving the grooves 93 on both sides to move in the direction of approaching each other. After the grooves 93 on the same side move to the lower part of the sliding frame 91 on the same side, under the action of gravity, the sliding frame 91 and the ball bearings 92 move downward, and the ball bearings 92 separate from the rudder bar 4, and the two clamping frames 61 continue to approach each other to clamp the rudder bar 4. The two clamping frames 61 move in the direction of moving away from each other, driving the grooves 93 on both sides to move away from each other. After the grooves 93 on the same side are separated from the lower part of the sliding frame 91 on the same side, the clamping frame 61 on the same side will lift the sliding frame 91 and the ball bearings 92 on the same side upward and reset them.

[0040] Embodiment 3: Based on embodiment 2, Figure 11-13As shown, a cleaning mechanism is also included. The cleaning mechanism is arranged on the housing 1, the clamping frame 61 and the driving frame 63. The cleaning mechanism is used to clean impurities attached to the rudder bar 4. The cleaning mechanism includes a square cylinder 71, a piston frame 72, an intake check valve 73, an exhaust check valve 74, a porous tube 75 and a hose 76. A square cylinder 71 is installed on one side of the housing 1 close to the motor 53 by bolts. A piston frame 72 is slidably provided in the square cylinder 71. The rod of the piston frame 72 passes through one side of the square cylinder 71. The rod of the piston frame 72 is connected to the driving frame 63. An intake check valve 73 is installed on the other side of the square cylinder 71. The intake check valve 73 is connected to the square cylinder 71. An exhaust check valve 74 is respectively installed on the other two sides of the square cylinder 71. The two exhaust check valves 74 are connected to the square cylinder 71. A porous tube 75 is respectively installed on the two clamping frames 61. A hose 76 is connected between the exhaust check valve 74 on the same side and the porous tube 75 on the same side.

[0041] It also includes rubber sheets 10 , and a plurality of rubber sheets 10 are evenly spaced and installed on one side of the two clamping frames 61 that are close to each other.

[0042] When the driving frame 63 moves toward the direction approaching the motor 53, the driving frame 63 drives the piston frame 72 to slide in the square cylinder 71, and the air in the square cylinder 71 is discharged from the porous tube 75 through the exhaust check valve 74 and the hose 76 in turn and blown onto the rudder bar 4. During the rotation of the rudder bar 4, the exhausted air can comprehensively clean the impurities remaining on the rudder bar 4, and avoid impurities being stuck between the clamping frame 61 and the rudder bar 4 when the clamping frame 61 clamps the rudder bar 4, thereby making the position of the rudder bar 4 more accurate after being fixed, and further improving the processing accuracy of the rudder bar 4. When the driving frame 63 moves in the direction away from the motor 53, the driving frame 63 drives the piston frame 72 to slide in the square cylinder 71, and draws outside air into the square cylinder 71 through the air intake check valve 73.

[0043] When the two clamping frames 61 are moved closer to each other to clamp the rudder bar 4, the surface of the rudder bar 4 can be prevented from being scratched under the action of the rubber sheet 10, and the friction force on the rudder bar 4 can also be increased, so as to fix the rudder bar 4 more stably and further improve the processing accuracy of the rudder bar 4.
