Description

Technical Field

[0001] The present invention relates to the field of broaching, and more specifically, to an auxiliary device applied to the broaching process of a large turbine. Background Art

[0002] Broaching is a mechanical processing method for machining the inner and outer surfaces of a workpiece using a broaching machine. The machining allowance of the workpiece is sequentially removed by the teeth of the broach with gradually increasing dimensions on each tooth. The tenon grooves of the aero-engine turbine disk workpiece are usually formed by broaching.

[0003] Since the shaped groove of the turbine disk has a certain slope, and the broach can only move linearly, the workpiece needs to be fixed on the indexing plate. After broaching one shaped groove, it is rotated by a certain angle and then the next shaped groove is machined. The workpiece needs to rotate synchronously with the turntable on the indexing plate. During the rotation and braking stop of the turntable, if the relative position between the workpiece and the turntable is not fixed, the workpiece will rotate relative to the turntable due to inertia during the continuous braking stop of the turntable. The size of the broached turbine disk is large, and the jaws of the turntable of the indexing plate are difficult to play a role. Multiple positioning holes can be opened on the turntable and the workpiece, and the workpiece and the turntable are fixed together to rotate synchronously by inserting positioning bolts into the positioning holes.

[0004] However, after the large turbine disk is placed on the turntable, it is not certain that the positioning holes of the workpiece and the turntable will be aligned, and the relative position between the workpiece and the turntable needs to be adjusted manually to align the positioning holes. Due to the large size of the workpiece, it is inconvenient for manual rotation operation. Summary of the Invention

[0027] Embodiment 1

[0028] As Figures 1-7 shown, an auxiliary device applied to the large - scale turbine broaching process includes a mounting base 101. A dividing plate 102 is provided on the mounting base 101. A plurality of vertical support shafts 104 are provided on the side of the turntable 103 of the dividing plate 102. The vertical support shafts 104 are arranged on a first unit that drives their vertical movement and locks at both ends of the movement path. An upper support plate 105 is provided on the side of the turntable 103 of the dividing plate 102. The upper support plate 105 is arranged on a second unit that drives its movement in the vertical direction and locks at the end of the movement. An adjusting mechanism is provided on the side of the turntable 103 of the dividing plate 102. The adjusting mechanism includes a rotating rod 106. One end of the rotating rod 106 is provided with a rotating head 107. The rotating head 107 is conical. A convex block 108 is provided on the conical side surface of the rotating head 107. The end of the rotating rod 106 away from the rotating head 107 is connected to one end of a first rotating shaft 110 through a coupling 109. The end of the first rotating shaft 110 away from the coupling 109 is connected to a first rotary power source 111 for driving the first rotating shaft 110 to rotate. The first rotary power source 111 is provided on the side of the turntable 103 of the dividing plate 102. A first adjusting frame 112 is provided on the rotating rod 106. One end of the first adjusting frame 112 is sleeved on the rotating rod 106. The first adjusting frame 112 is rotatably connected to the rotating rod 106. The end of the first adjusting frame 112 away from the rotating rod 106 is hinged to the output end of a second adjusting frame 113. The end of the second adjusting frame 113 away from the first adjusting frame 112 is hinged to the output end of a first linear driving mechanism 114. The first linear driving mechanism 114 is provided on the side of the first rotary power source away from the turntable 103.

[0029] Working principle of the present invention: In the initial state, the output shaft of the first linear driving mechanism 114 contracts. The second adjusting frame 113 is driven by the first linear driving mechanism 114 to drive the first adjusting frame 112 to rotate around the connection point of the coupling 109. The first adjusting frame 112 drives the rotating rod 106 to rotate around the connection point of the coupling 109 in a direction away from the turntable 103. The angle between the rotating rod 106 and the first rotating shaft 110 increases. At this time, the distance between the rotating head 107 and the turntable 103 is relatively far.

[0030] Place the large turbine disk or disk-shaped workpiece on the turntable 103 of the indexing table 102. A plurality of vertical support shafts 104 are driven to rise and locked by the first unit, restricting the workpiece to the middle of the turntable 103. The upper support plate 105 is driven to rise by the second unit, and the upper support plate 105 contacts and locks with the edge of the workpiece. The vertical support shafts 104 and the upper support plate 105 center the workpiece with respect to the turntable 103, and when the workpiece rotates relative to the turntable 103, it will not deviate from the center of the turntable 103.

[0031] When the fixing holes on the workpiece cannot be aligned with the fixing holes on the turntable 103, the fixing bolts cannot be inserted into the workpiece and the turntable 103, and the workpiece and the turntable 103 cannot be fixed. The output shaft of the first linear drive mechanism 114 extends, and the second adjusting frame 113 drives the rotating rod 106 to rotate towards the workpiece through the first adjusting frame 112. The rotating head 107 moves into the shaped groove on the edge of the turbine disk under the drive of the rotating head 107;

[0032] A shaped groove on the edge of the turbine disk has upper and lower openings. The cross-section perpendicular to the broaching path is trapezoidal in reverse, and it has a certain angle with respect to the central axis of the turbine disk. When the turbine disk is placed horizontally, the groove surface with the inclined surface facing up in one of its shaped grooves is surface A, and the groove surface with the inclined surface facing down is surface B;

[0033] The rotation and locking of the indexing table 102 belong to the prior art. Slightly rotate the turntable 103 of the indexing table 102 so that the distance between the rotating head 107 and one side wall of the shaped groove is less than the height of the convex block 108 on the rotating head 107, and then lock the indexing table 102. The first rotary power source 111 drives the rotating head 107 to rotate through the rotating rod 106. The convex block 108 on the rotating head 107 continuously knocks on the side wall of surface A of the shaped groove of the turbine disk during rotation, causing the turbine disk to rotate in the vibration towards the direction of the side wall where the rotating head 107 is approaching. While the turbine disk rotates in the fixed direction, the output shaft of the first linear drive mechanism 114 continues to extend, and the rotating head 107 moves downward in a direction parallel to the center line of the turntable 103 during rotation. During this process, the convex block 108 on the rotating head 107 keeps knocking on the side wall of surface A of the shaped groove, and the workpiece continuously rotates relative to the turntable 103. When the rotating head 107 moves to the opening near the bottom surface of the turntable 103 of the shaped groove, release the brake of the indexing table 102 to make the indexing table in a state of flexible rotation. The first linear drive mechanism 114 drives the rotating head 107 to move upward to the upper part of the shaped groove. The indexing table 102 cooperates again to make the side wall of surface A of the shaped groove and the rotating head 107 at an appropriate distance, lock the indexing table 102, and the rotating head 107 can continue to knock on the side wall of surface A of the shaped groove to make the workpiece rotate relative to the turntable 103. Repeat the operation until the positioning holes on the workpiece are aligned with the positioning holes on the turntable 103.

[0034] If it is necessary to rotate the workpiece in the other direction, unlock the indexing plate 102. The first linear drive mechanism 114 drives the rotating head 107 to move to the bottom end of a shaped groove. Rotate the indexing plate 102 so that the rotating head 107 maintains a certain distance from the groove wall of the B surface of the shaped groove, and this distance is less than the height of the convex block 108 on the rotating head 107. The first rotary power source 111 drives the rotating head 107 to rotate. The convex block 108 on the rotating head 107 continuously knocks on the groove wall of the B surface of the turbine disk groove during rotation, causing the turbine disk to rotate in the direction approaching the groove wall on the side of the rotating head 107 during vibration. This process is the same as the process in which the convex block 108 on the rotating head 107 acts on the groove wall of the A surface of the shaped groove. During the process of the convex block 108 knocking on the groove wall, the workpiece and the turntable 103 rotate relatively. The first linear drive mechanism 114 drives the rotating head 107 to move upward. During this process, the convex block 108 on the rotating head 107 continues to knock on the groove wall of the B surface of the shaped groove, and the workpiece continuously rotates relative to the turntable 103. When the rotating head 107 moves to the opening of the shaped groove near the top surface of the turntable 103, release the brake of the indexing plate 102 to make the indexing plate in a state of flexible rotation. The first linear drive mechanism 114 drives the rotating head 107 to move downward to the opening of the shaped groove near the bottom surface of the turntable 103. The indexing plate 102 cooperates again to make the groove wall of the B surface of the shaped groove and the rotating head 107 at an appropriate distance, lock the indexing plate 102, and the rotating head 107 can continue to knock on the groove wall of the B surface of the shaped groove to make the workpiece rotate relative to the turntable 103. Repeat the operation until the positioning holes on the workpiece are aligned with the positioning holes on the turntable 103.

[0035] The shaped groove is a part to be broached and has machining allowance left. The knocking of the convex block 108 will not damage the workpiece and will not affect the subsequent broaching. Compared with manually prying the workpiece to rotate it relative to the turntable 103, the damage to the workpiece is smaller.

[0036] Through the above operations, the large turbine disk workpiece can be rotated and adjusted relative to the turntable 103 after being placed on the turntable 103 of the indexing plate 102, which is convenient for further fixing operations, avoids manually moving the large turbine disk, saves manpower, and at the same time avoids damaging the workpiece.

[0037] In an embodiment of the present invention, the first unit includes an oil cylinder seat 115. The oil cylinder seat 115 is disposed on the outer peripheral surface of the turntable 103. There is a gap between the oil cylinder seat 115 and the turntable 103. The oil cylinder seat 115 is fixedly connected to the indexing plate 102 by bolts. The vertical support shaft 104 is inserted into the interior of the oil cylinder seat 115. The vertical support shaft 104 extends into the oil cylinder seat 115 from the top surface of the oil cylinder seat 115 and penetrates through the oil cylinder seat 115. A first hole with a clearance fit with the vertical support shaft 104 is provided in the oil cylinder seat 115. A horizontal support shaft 116 is provided in the oil cylinder seat 115. A first oil cylinder 117 is provided along the axial direction of the horizontal support shaft 116. The long axis of the first oil cylinder 117 is fixedly connected to the horizontal support shaft 116. The first oil cylinder 117 is fixedly connected to the oil cylinder seat 115 by bolts. A slope is provided at the top of the horizontal support shaft 116. The slope gently rises from the end of the horizontal support shaft 116 away from the first oil cylinder 117 to the other end. A second hole 118 with a clearance fit with the maximum cross-sectional area of the horizontal support shaft 116 is provided in the oil cylinder seat 115. The second hole 118 is perpendicular to the first hole. The horizontal support shaft 116 passes through the vertical support shaft 104. A third hole 119 is provided on the vertical support shaft 104. A slope parallel to the slope of the horizontal support shaft 116 is provided on the top surface of the third hole 119.

[0038] When the first oil cylinder 117 is fed oil through the oil inlet hole and discharged oil through the oil outlet hole, the long axis of the first oil cylinder 117 pushes the horizontal support shaft 116 towards the orifice of the turntable brake oil cylinder seat 115. The slope of the horizontal support shaft 116 jacks up the vertical support shaft 104. When the stroke of the vertical support shaft 104 reaches the position and is in close contact with the workpiece, the first oil cylinder 117 will no longer be fed oil and maintain the current state. When the first oil cylinder 117 is fed oil through the oil outlet hole and discharged oil through the oil inlet hole, the long axis of the first oil cylinder 117 pulls the horizontal support shaft 116 back towards the orifice of the turntable brake oil cylinder seat 115. The vertical support shaft 104 falls back. The vertical support shaft 104 is disengaged from the workpiece. The first oil cylinder 117 will no longer be fed oil and maintain the current state.

[0039] Further, one end of the first oil cylinder 117 away from the lateral support shaft 116 is provided with a first bracket 124. One end of the first bracket 124 is fixedly connected to the first oil cylinder 117, and the other end is bent to one side of the first oil cylinder 117 and keeps a certain distance from the first oil cylinder 117. The short axis of the first oil cylinder 117 extends from the end connected with the first bracket 124. The first bracket 124 is provided with a hole for the short axis to pass through. The part of the first bracket 124 bent to one side of the first oil cylinder 117 is provided with a hollow groove. Two signal receivers 125 are arranged in the hollow groove. The two signal receivers 125 are adjustably arranged in the hollow groove through nuts. The receiving end of the signal receiver 125 faces the first oil cylinder 117. A proximity signal piece 126 is sleeved on the short axis of the first oil cylinder 117. The proximity signal piece 126 is bent in the same way as the first bracket 124. The bent part of the proximity signal piece 126 passes through the first bracket 124 and extends between the first bracket 124 and the first oil cylinder 117. A first spring 127 is arranged between the first bracket 124 and the proximity signal piece 126. The first spring 127 is sleeved on the short axis of the first oil cylinder 117 or the second oil cylinder 121.

[0040] When the inclined surface of the lateral support shaft 116 jacks up the vertical support shaft 104, the short axis of the first oil cylinder 117 drives the proximity signal piece 126 forward. When the proximity signal piece 126 moves below the signal receiver 125, the signal receiver 125 will transmit the signal to the processor, indicating that the first oil cylinder 117 has extended in place, the vertical support shaft 104 has reached the stroke and the workpieces are in close contact. The first oil cylinder 117 will no longer supply oil and maintain the current state. When the vertical support shaft 104 falls back, at the same time, the short axis of the first oil cylinder 117 drives the proximity signal piece 126 backward. When the proximity signal piece 126 moves below the signal receiver 125, the signal receiver 125 will transmit the signal to the processor, indicating that the first oil cylinder 117 has retracted in place, the vertical support shaft 104 has disengaged from the workpiece, and the first oil cylinder 117 will no longer supply oil and maintain the current state. The first spring 127 is provided to facilitate the reset of the proximity signal piece 126.

[0041] In an embodiment of the present invention, the second unit includes a lower support plate 120. The lower support plate 120 is fixedly arranged on the side surface of the turntable 103 by bolts. The lower support plate 120 is perpendicular to the tabletop of the turntable 103. A second oil cylinder 121 is provided on the upper part of the lower support plate 120. The second oil cylinder 121 is fixedly connected to the lower support plate 120 by bolts. The axis of the long shaft of the second oil cylinder 121 is parallel to the plate surface of the lower support plate 120. A square groove 122 is provided at the top of the lower support plate 120. The square groove 122 extends to both plate surfaces of the lower support plate 120 to form an opening. The long shaft of the second oil cylinder 121 penetrates the side surface of the lower support plate 120 and extends into the square groove 122. A moving block 123 is provided in the square groove 122. A threaded hole is provided at one end of the moving block 123. Threads are provided on the long shaft of the second oil cylinder 121. The long shaft of the second oil cylinder 121 is helically connected to the moving block 123. The thickness of the end of the moving block 123 close to the second oil cylinder 121 is greater than the thickness of the other end. The upper support plate 105 is arranged on the top of the lower support plate 120. A plurality of cylindrical pins are provided at the bottom of the upper support plate 105. Holes for clearance fit with the cylindrical pins are provided at the top of the lower support plate 120. An inclined surface for mating with the top of the moving block 123 is provided at the bottom of the upper support plate 105.

[0042] When oil enters through the oil inlet hole of the second oil cylinder 121 and exits through the oil outlet hole, the long shaft of the second oil cylinder 121 pushes the moving block 123 out towards the orifice of the lower support plate 120. The inclined surface of the moving block 123 jacks up the upper support block. When the stroke of the moving block 123 reaches the position, the upper support block is in close contact with the workpiece, and the second oil cylinder 121 will no longer admit oil and maintain the current state. When oil enters through the oil outlet hole of the second oil cylinder 121 and exits through the oil inlet hole, the long shaft of the second oil cylinder 121 pulls the moving block 123 back from the orifice of the lower support plate 120. The upper support block falls back, and the upper support block is disengaged from the workpiece. The second oil cylinder 121 will no longer admit oil and maintain the current state.

[0043] Further, one end of the first oil cylinder 117 away from the transverse support shaft 116 is provided with a first support 124. One end of the first support 124 is fixedly connected to the first oil cylinder 117, and the other end is bent to one side of the first oil cylinder 117 and kept at a certain distance from the first oil cylinder 117. The short axis of the first oil cylinder 117 extends from the end connected with the first support 124. The first support 124 is provided with a hole for the short axis to pass through. The part of the first support 124 bent to one side of the first oil cylinder 117 is provided with a hollow groove. Two signal receivers 125 are arranged in the hollow groove. The two signal receivers 125 are adjustably arranged in the hollow groove through nuts. The receiving end of the signal receiver 125 faces the first oil cylinder 117. A proximity signal piece 126 is sleeved on the short axis of the first oil cylinder 117. The proximity signal piece 126 is bent in the same way as the first support 124. The bent part of the proximity signal piece 126 passes through the first support 124 and extends between the first support 124 and the first oil cylinder 117. A first spring 127 is arranged between the first support 124 and the proximity signal piece 126. The first spring 127 is sleeved on the short axis of the first oil cylinder 117.

[0044] When the inclined surface of the transverse support shaft 116 jacks up the vertical support shaft 104, the short axis of the first oil cylinder 117 drives the proximity signal piece 126 forward. When the proximity signal piece 126 moves below the signal receiver 125, the signal receiver 125 will transmit the signal to the processor, indicating that the first oil cylinder 117 has extended in place, the vertical support shaft 104 has reached the stroke and the workpieces are in close contact. The first oil cylinder 117 will no longer supply oil and maintain the current state. When the vertical support shaft 104 falls back, at the same time, the short axis of the first oil cylinder 117 drives the proximity signal piece 126 backward. When the proximity signal piece 126 moves below the signal receiver 125, the signal receiver 125 will transmit the signal to the processor, indicating that the first oil cylinder 117 has retracted in place, the vertical support shaft 104 has been disengaged from the workpiece, the first oil cylinder 117 will no longer supply oil and maintain the current state. The first spring 127 is arranged to facilitate the reset of the proximity signal piece 126.

[0045] Further, the short axis of the second oil cylinder 121 extends from the end away from the moving block 123. The second oil cylinder 121 is provided with a first support 124, two signal receivers 125 and a proximity signal piece 126 with the same structure as those provided at one end of the first oil cylinder 117 away from the transverse support shaft 116.

[0046] In an embodiment of the present invention, the cross-section of the outer peripheral surface of the vertical support shaft 104 is circular, and the diameter of the upper part of the vertical support shaft 104 is larger than that of its lower part. The increase in the diameter of the upper part of the vertical support shaft 104 enables the vertical support shaft 104 not to get stuck in the V-shaped groove after rising and contacting the workpiece.

[0047] In an embodiment of the present invention, the first linear drive mechanism 114 is a cylinder or an electric push rod.

[0048] In an embodiment of the present invention, the bottom surface of the third hole 119 of the vertical support shaft 104 is lower than the bottom surface of the second hole 118, so that when the vertical support shaft 104 is lifted by the lateral support shaft 116, the bottom surface of the third hole 119 will not abut against the bottom surface of the lateral support shaft 116, thereby preventing the vertical support shaft 104 from not being lifted.

[0049] In an embodiment of the present invention, a side baffle 128 is provided on the side of the lower support plate 120 close to the turntable 103. The side baffle 128 is locked to the side of the lower support plate 120 by a nut. The side baffle 128 is provided to prevent iron filings generated during processing from entering the square groove 122.

[0050] In an embodiment of the present invention, there are two adjusting mechanisms, namely a first adjusting mechanism and a second adjusting mechanism. The first adjusting mechanism and the second adjusting mechanism are symmetric about the central axis of the turntable 103. The two adjusting mechanisms are symmetrically arranged and act on the workpiece at the same time, improving the adjusting efficiency and making the force on the workpiece uniform.

[0051] The embodiments of this embodiment have been described above with reference to the accompanying drawings. However, this embodiment is not limited to the above specific implementation manners. The above specific implementation manners are merely illustrative and not restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make many forms without departing from the purpose of this embodiment and the scope protected by the claims, and all belong to the protection scope of this embodiment.
