A self-aligning honing tool

Abstract

This invention discloses an automatically self-aligning honing tool, relating to the field of honing processing technology. It includes a structural component comprising a fixed cylinder, a connecting column, and a honing strip. The connecting column is fixedly disposed on one side of the fixed cylinder, and a square through hole is provided on the side of the fixed cylinder. When the honing tool grinds the inner wall of the bushing, the inner wall of the bushing is continuously ground by the honing strip, which causes the inner diameter of the bushing to increase. Under the action of the spring force, the fixed plate drives the honing strip to continuously expand outward, and the spring force can also increase the friction between the honing strip and the bushing. Thus, while ensuring that the honing tool and the bushing are concentric, the honing strip can also adaptively adjust the inner diameter of the bushing. At the same time, as the honing strip expands outward, the spring force of the spring force begins to decrease. At this time, the friction between the honing strip and the bushing may be insufficient, but the anti-return element can keep the honing strip moving in one direction. Therefore, when the spring force of the spring force is insufficient, the honing strip can still be tightly attached to the inner wall of the bushing.

Description

Technical Field

[0001] This invention relates to the field of honing technology, and more particularly to a honing tool with automatic self-aligning capability. Background Technology

[0002] Steam turbine valves are crucial components in steam turbine operation, consisting of main steam valves and regulating steam valves. Their function is to control the turbine speed during startup and regulate load changes during normal operation. Because regulating steam valves frequently handle changes, jamming can have serious consequences. Disassembly and inspection of jammed valves revealed obvious traces of steam-blocking rings on the valve stem. Clearance measurements showed a severely reduced fit clearance, even reaching zero in some cases. Therefore, the primary cause of valve jamming is insufficient clearance between the valve stem and the bushing.

[0003] To repair bushings, existing techniques typically use honing to grind the inner side of the bushing. However, current honing tools usually use a conical surface to mechanically adjust the honing strip, and cannot adaptively adjust the position of the honing strip according to the inner diameter of the bushing in a timely manner, resulting in the bushing becoming misaligned after honing. Summary of the Invention

Under the action of the spring force, the fixed plate drives the honing strip to expand outward continuously, and the spring force can also increase the friction between the honing strip and the bushing. Thus, while ensuring that the honing tool and the bushing are concentric, the honing strip can also adaptively adjust the inner diameter of the bushing. At the same time, as the honing strip expands outward, the spring force of the spring force begins to decrease. At this time, the friction between the honing strip and the bushing may be insufficient, but the anti-return element can keep the honing strip moving in one direction. Therefore, when the spring force of the spring force is insufficient, the honing strip can still be tightly attached to the inner wall of the bushing. Attached Figure Description

[0030] Example 1

[0031] Reference Figures 1-2 The first embodiment of the present invention provides an automatically self-aligning honing tool, comprising a structural component 100, including a fixed cylinder 101, a connecting post 102, and a honing strip 103. The connecting post 102 is fixedly disposed on one side of the fixed cylinder 101. A square through hole is provided on the side of the fixed cylinder 101. The honing strip 103 is slidably disposed inside the square through hole. The square through hole is disposed on both sides of the fixed cylinder 101. A honing strip 103 is disposed inside each square through hole. The connecting post 102 is used to connect to an external power machine to drive the honing tool. The honing strip 103 is used to polish the inner wall of the bushing.

[0032] The adaptation component 200 includes an expanding member 201, a contracting member 202, and a driving member 203. The expanding member 201 is fixedly disposed on one side of the honing strip 103, the contracting member 202 is disposed on one side of the expanding member 201, and the driving member 203 is disposed on one side of the connecting column 102. The auxiliary component 300 includes a transmission member 301, a check member 302, an adjusting member 303, and a rotating member 304. The transmission member 301 is disposed inside the fixed cylinder 101, the check member 302 is disposed at the end of the transmission member 301, the adjusting member 303 is disposed on one side of the contracting member 202, and the rotating member 304 is disposed inside the fixed cylinder 101.

[0033] In use: Connect the honing tool to the power unit, then use the adaptation component 200 to retract the honing strip 103 to the appropriate position, and then insert the honing tool into the bushing. During the rotation of the honing tool, the auxiliary component 300 restricts the sliding of the honing strip 103, ensuring that the honing strip 103 has sufficient pressure on the inner wall of the bushing.

[0034] Example 2

[0035] Reference Figures 2-3 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the outer expansion member 201 includes a support plate 201a, a spring 201b, and a fixing plate 201c. The support plate 201a is fixedly disposed inside the fixing cylinder 101, and the spring 201b is fixedly disposed on the side of the support plate 201a. Two springs 201b are provided on each side of the support plate 201a to ensure sufficient elasticity. The fixing plate 201c is fixedly disposed at the end of the spring 201b away from the support plate 201a. A groove is provided on the side of the fixing plate 201c, and the honing strip 103 is fixedly disposed inside the groove.

[0036] The shrinkage component 202 includes a double-threaded screw 202a, a collar 202b, a connecting rod 202c, a sliding hole 202d, and a limiting rod 202e. The double-threaded screw 202a is disposed through the top of the fixed cylinder 101 and rotatably disposed inside the fixed cylinder 101. The double-threaded screw 202a has two types of threads with opposite directions symmetrically distributed on the same rod body. The collar 202b is sleeved on the side of the double-threaded screw 202a. Each double-threaded screw 202a... Two collars 202b are provided on the outer side of 2a. Each collar 202b is connected to a thread with a different direction of rotation. The inner side of the collar 202b is threaded to the side of the double-threaded screw 202a. The connecting rod 202c is rotatably set on the inner side of the collar 202b. The sliding hole 202d is opened on the side of the connecting rod 202c. The limiting rod 202e is fixedly set on the side of the fixing plate 201c. The limiting rod 202e and the inner side of the sliding hole 202d are in sliding fit.

[0037] The driving component 203 includes a gear 203a, a gear sleeve 203b, and a top plate 203c. The top of the double-threaded screw 202a extends to the outside of the fixed cylinder 101. The gear 203a is fixedly disposed on the side of the double-threaded screw 202a. The inner side of the gear sleeve 203b is provided with teeth. The gear sleeve 203b and the gear 203a mesh together. The inner side of the gear sleeve 203b is slidably disposed on the side of the connecting post 102. The top plate 203c is fixedly disposed on the side of the connecting post 102. The bottom of the top plate 203c abuts against the top of the gear sleeve 203b. The top plate 203c can restrict the gear sleeve 203b between the gear 203a and the top plate 203c, thereby preventing the gear sleeve 203b from sliding freely.

[0038] In use: When the honing tool grinds the inner wall of the bushing, the inner wall of the bushing is continuously ground by the honing strip 103, which makes the inner diameter of the bushing larger. Under the action of the spring 201b, the fixing plate 201c drives the honing strip 103 to expand outward continuously. The spring 201b can also increase the friction between the honing strip 103 and the bushing. Thus, while ensuring that the honing tool and the bushing are concentric, the honing strip 103 can also adaptively adjust the inner diameter of the bushing.

[0039] To ensure that the honing tool can enter the bushing, the honing strip 103 needs to be pulled into the fixed cylinder 101 a portion. At this time, it is only necessary to rotate the gear sleeve 203b. The gear sleeve 203b drives the double-threaded screw 202a to rotate. After the double-threaded screw 202a rotates, the thread drives the collar 202b to approach each other. As the collar 202b approaches, the connecting rod 202c is pulled. When the inner side of the sliding hole 202d and the side of the limiting rod 202e abut, the fixed plate 201c is pulled by the connecting rod 202c and drives the honing strip 103 to move into the fixed cylinder 101.

[0040] After moving to a position where the honing tool can be placed in the bushing, the gear sleeve 203b is reversed. At this time, the connecting rod 202c swings in the opposite direction. Since the honing tool is restricted from moving by the bushing, the fixed plate 201c and the limiting rod 202e also stop moving. As the connecting rod 202c swings, the sliding hole 202d and the limiting rod 202e no longer abut and a certain distance is left. As the inner diameter of the bushing is ground, the honing strip 103 expands outward. The fixed plate 201c can drive the limiting rod 202e to slide within the distance left by the sliding hole 202d, thereby preventing the connecting rod 202c from restricting the adaptive expansion of the honing strip 103.

[0041] The remaining structure is the same as that in Example 1.

[0042] Example 3

[0043] Reference Figures 4-8 This is the third embodiment of the present invention, which differs from the second embodiment in that: the transmission component 301 includes a limiting plate 301a, a sliding frame 301b, an arc-shaped push rod 301c, an arc-shaped sleeve 301d, and a second spring 301e. The limiting plate 301a is fixedly disposed inside the fixed cylinder 101 and is located on both sides of each honing strip 103. The sliding frame 301b is slidably disposed inside the limiting plate 301a. The arc-shaped push rod 301c is fixedly disposed inside the fixed cylinder 101. The arc-shaped sleeve 301d is fixedly disposed on the side of the sliding frame 301b. The second spring 301e is fixedly disposed inside the arc-shaped sleeve 301d. The arc-shaped push rod 301c is slidably disposed inside the arc-shaped sleeve 301d, and the second spring 301e abuts against the end of the arc-shaped push rod 301c.

[0044] The check valve 302 includes a check groove 302a, a rotating wheel 302b, a check nozzle 302c, a baffle 302d, a check plate 302e, and a spring 302f. Multiple check grooves 302a are provided on the side of the honing strip 103 and arranged in multiple groups on the side of the honing strip 103. The rotating wheel 302b is rotatably mounted at the end of the sliding frame 301b. The check nozzle 302c is fixedly mounted on the side of the rotating wheel. The return nozzle 302c abuts against the inner side of the check groove 302a. The baffle 302d is fixedly installed at the end of the sliding frame 301b. The check plate 302e abuts against the side of the baffle 302d. The spring 302f is fixedly installed on the side of the check plate 302e and abuts against the side of the sliding frame 301b. The spring 302f can limit the rotation of the wheel 302b, thereby preventing the wheel 302b from flipping over and failing to reset.

[0045] The adjusting component 303 includes an adjusting plate 303a, a limiting groove 303b, a circular plate 303c, an extension plate 303d, a support base 303e, and a spring 303f. The adjusting plate 303a is slidably disposed inside the fixed cylinder 101. The limiting groove 303b is formed on the side of the adjusting plate 303a. The circular plate 303c is fixedly disposed at the end of the sliding frame 301b near the adjusting plate 303a. The extension plate 303d is fixedly disposed on the side of the adjusting plate 303a. The support base 303e is fixedly disposed inside the fixed cylinder 101. The two ends of the spring 303f are respectively fixedly disposed on the side of the adjusting plate 303a and the side of the support base 303e. The spring 303f is used to reset the adjusting plate 303a after it has moved.

[0046] The rotating component 304 includes a rotating plate 304a, a second limiting groove 304b, a cross groove 304c, a cross post 304d, and a fifth spring 304e. The rotating plate 304a is rotatably disposed on the inner bottom of the fixed cylinder 101. The second limiting groove 304b is opened on the side of the rotating plate 304a. The cross groove 304c is opened at the top center of the rotating plate 304a. The cross post 304d is disposed through the inner side of the double-threaded screw 202a. The two ends of the fifth spring 304e are respectively fixedly disposed on the top of the double-threaded screw 202a and on one side of the top of the cross post 304d. When the cross post 304d slides, the fifth spring 304e is used to reset the cross post 304d. The extension plate 303d is slidably disposed on the inner side of the second limiting groove 304b. The bottom of the double-threaded screw 202a is rotatably disposed at the top center of the rotating plate 304a. The top of the cross post 304d abuts against the inner side of the toothed sleeve 203b.

[0047] In use: As the honing strip 103 expands outward, the elastic force of the spring 201b begins to decrease. At this time, the friction between the honing strip 103 and the bushing may be insufficient. In order to prevent this from happening, the check valve 302 can keep the honing strip 103 moving in one direction. Therefore, when the elastic force of the spring 201b is insufficient, the honing strip 103 can still be tightly attached to the inner wall of the bushing.

[0048] When the honing strip 103 expands outward, the inner wall of the bushing also exerts a reaction force on the honing strip 103. After being subjected to the reaction force, the honing strip 103 begins to move towards the inner side of the fixed cylinder 101. During the movement, the inner side of the check groove 302a squeezes the check nozzle 302c. After being subjected to force, the check nozzle 302c drives the rotating wheel 302b to rotate. However, because the check plate 302e is blocked by the baffle 302d, the rotating wheel 302b cannot rotate. Therefore, under the obstruction of the check nozzle 302c, the honing strip 103 can only move towards the side away from the fixed cylinder 101.

[0049] If the check valve 302 continues to function, the honing strip 103 cannot retract. Therefore, in order to ensure that the honing strip 103 can retract, the gear sleeve 203b needs to be pressed down while rotating. After the gear sleeve 203b moves down, it drives the cross pin 304d to overcome the elastic force of the spring 304e and slide along the inner side of the double-threaded screw 202a until the cross pin 304d slides into the cross groove 304c. At this time, the double-threaded screw 202a can drive the rotating plate 304a to rotate.

[0050] At this point, simply rotating the gear sleeve 203b by a certain angle will allow the double-threaded screw 202a to drive the rotating plate 304a to rotate. After the rotating plate 304a rotates, the extension plate 303d slides out of the limiting groove 2 304b. Under the support force of the extension plate 303d, the adjusting plate 303a overcomes the spring 4 303f and slides upward. Due to the movement of the adjusting plate 303a, the circular plate 303c slides into the limiting groove 1 303b. Due to the movement of the spring 2 301... e is in a state of compression against the arc-shaped push rod 301c. Therefore, after the circular plate 303c slides into the limiting groove 303b, the sliding frame 301b is squeezed by the arc-shaped push rod 301c and slides towards the side of the adjusting plate 303a. After the sliding frame 301b slides, the check piece 302 located at the end of the sliding frame 301b is completely taken away from the check groove 302a. Without the obstruction of the check piece 302, the honing strip 103 can be retracted by the retraction piece 202.

[0051] The remaining structure is the same as that in Example 2.
