Description

Technical Field

[0001] This invention relates to the field of intaglio honing technology, specifically to a self-deflecting conformal ultrasonic honing device for intaglio honing. Background Technology

[0002] Honing technology is crucial in the machining of rifling grooves on large-caliber artillery barrels. In recent years, honing-related patents have emerged continuously, such as the patent for "A Rifling Honing Head" (CN110757331A), which improves the machining accuracy of rifling through innovative structural design, but does not address the machining of complex curved surfaces of artillery barrel grooves; the patent for "Radial Ultrasonic Honing Processing Device" (CN106181743A) uses ultrasonic vibration to improve the surface quality of the honing inner wall, which can improve the machining effect to a certain extent, but it is difficult to adapt to the curvature changes of the spiral grooves on large-caliber artillery barrels, the honing stone is not in stable contact with the side of the groove, the grinding force fluctuates, resulting in uneven material removal, insufficient dimensional accuracy, high surface roughness, and the honing stone is prone to clogging and wear, leading to low processing efficiency. Summary of the Invention

[0003] In order to solve the problem that existing wire honing devices often have unstable adhesion between the honing stone and the side of the wire during wire honing, resulting in fluctuations in grinding force and thus poor honing quality and low processing efficiency, this invention provides a new self-deflecting conformal guided ultrasonic honing device for wire honing.

[0004] This invention is achieved using the following technical solution: A self-deflecting conformal guided ultrasonic honing device for intaglio machining includes a self-deflecting conformal guided honing mechanism, an ultrasonic vibration mechanism, and a ball joint mechanism. The self-deflecting conformal honing mechanism includes a honing housing, an expansion core, and multiple tilting blocks. The expansion core is coaxial and axially slidably connected inside the honing housing. The honing housing has multiple grooves evenly distributed circumferentially. The bottom ends of the multiple tilting blocks are radially slidably connected to the multiple grooves and are all adapted to abut against the expansion core. Each tilting block has a sub-seat above it. Each sub-seat and the corresponding tilting block have a central bolt in the middle. The bottom of the central bolt is fixed to the top of the tilting block, and the top of the central bolt is rotatably connected to the bottom surface of the sub-seat. A torsion spring is fitted on the central bolt. Each sub-seat and the corresponding tilting block have guide bolts at both ends. The bottom of the guide bolt is fixed to the top surface of the tilting block. The bottom surface of the sub-seat has a T-slot adapted to the top of the guide bolt, and the diameter of the T-slot is larger than the top diameter of the guide bolt (to facilitate small-angle torsion of the sub-seat relative to the tilting block). Each sub-seat has a conformal whetstone fixed on it. The ultrasonic vibration mechanism includes an ultrasonic housing and multiple flexible rods. A coaxially arranged amplitude transformer and piezoelectric transducer are fixed inside the ultrasonic housing. The front end of the ultrasonic housing is fixed to the rear end of the honing housing. The front ends of the multiple flexible rods are respectively fixed to the rear ends of multiple sub-seats. The rear ends of the multiple flexible rods extend into the ultrasonic housing and are circumferentially and evenly fixed to the front end of the amplitude transformer. The ball joint mechanism includes a ball joint, a ball joint seat adapted to the rear end of the ball joint, and a ball joint front end fixed to the rear end of the ultrasonic housing; The ball joint mechanism, ultrasonic vibration mechanism, and self-deflecting conformal honing mechanism all have through holes at their centers to facilitate the sliding of the mandrel until it abuts against the center of the rear end face of the expanded core.

[0005] In use, the ball joint seat is fixed to the honing machine, and the mandrel on the honing machine is inserted into the through hole until it abuts against the rear end face of the expanding mandrel. When the ultrasonic honing device enters the groove to be processed, the mandrel of the honing machine is fed axially, causing the expanding mandrel to push the inclined block to expand radially, which in turn drives the contour stone to expand radially. At the same time, the ball joint mechanism achieves rotation, so that the contour stone is in continuous contact with the groove. Due to the spiral shape of the groove, the torsion spring automatically twists according to changes in cutting force and wear of the honing stone, causing the honing stone to adjust its angle in the tangential direction. This maintains the optimal grinding state between the honing stone's sidewall and the groove's sidewall. Specifically, when a large tangential force is applied to a certain position of the honing stone, the torsion spring twists at a certain angle, making the grinding surface of the honing stone more aligned with the direction of the tangential force, thereby reducing fluctuations in grinding force and improving processing quality. After honing is completed, the torsion spring returns to its original angle when there is no cutting force, preparing for the next honing operation. Simultaneously, ultrasonic vibration energy is directionally transmitted, the piezoelectric transducer generates vibration, the energy is focused by the amplitude transformer, and transmitted to the auxiliary seat through the flexible rod, causing the honing stone to vibrate and improving the honing processing quality.

[0006] Furthermore, one end of the torsion spring is fixed to the sub-seat and the other end is fixed to the honing housing, making the structure more specific and standardized.

[0007] Furthermore, the bottom ends of the multiple inclined blocks are fitted with the groove with a clearance, and the two ends of the multiple inclined blocks are respectively tightened by two sealing rings, realizing the sliding connection between the bottom ends of the multiple inclined blocks and the groove (the sliding connection means that the two can slide against each other and are connected without separating), which is simple in structure and easy to implement.

[0008] Furthermore, each inclined block has a positioning groove at both ends for positioning the sealing ring, which facilitates the sealing ring to tighten the inclined block and improves the stability of the overall structure.

[0009] Furthermore, the expansion core is formed by multiple frustums connected in a straight line, and a cylinder is coaxially fixed at the front end of each frustum. The bottom surface of the tilting block is a multi-segmented inclined surface that fits the frustum, and there is a clearance groove between two adjacent inclined surfaces. The structure is specific and standardized, which makes the radial movement of the tilting block more stable and further ensures the honing quality.

[0010] Furthermore, the ultrasonic housing includes a cylindrical shell, a front cover, a rear cover, a vibrating disk, and a fixing ring plate. Through holes are located on the front and rear covers. A fixing hole is located at the center of the vibrating disk. The front end of the amplitude transformer is a small-diameter end, and the rear end is a large-diameter end. The front end of the amplitude transformer has external threads and is fitted with a fastening nut. The fixing hole of the vibrating disk is fitted onto the front end of the amplitude transformer and located behind the fastening nut. Multiple flexible rods extend into the front cover and are circumferentially and evenly fixed to the vibrating disk. The rear end of the amplitude transformer is welded and fixed to the front end of the piezoelectric transducer. The rear end of the piezoelectric transducer is fixed inside the cylindrical shell by the fixing ring plate. The structure is specific and standardized, and the vibration of the amplitude transformer is amplified through the vibrating disk.

[0011] Furthermore, the honing housing includes a stepped housing body, with internal threads at the small-diameter end of the housing body, multiple grooves at the large-diameter end of the housing body, a stepped front cover, the large-diameter end of the front cover being fixed to the front port of the cylindrical housing, and external threads at the small-diameter end of the front cover that are adapted to the small-diameter end of the housing body. The specific structure for fixing the honing housing to the ultrasonic outer shell is described.

[0012] Furthermore, the non-grooved portion of the large-diameter end of the housing body is equipped with multiple limiting blocks to limit the torsion angle of the honing stone, preventing excessive torsion angle from causing mis-processing and affecting honing quality.

[0013] Furthermore, the ball joint seat includes a front ball joint cover and a rear ball joint cover, which are fixed by pre-tightening bolts. The structure is specific and standardized, making it easy to assemble and disassemble.

[0014] Furthermore, each sub-base can be detachably fixed with an oilstone base, and the contour oilstone is glued and fixed to the oilstone base, making the structure more specific and standardized, and facilitating the replacement of the contour oilstone later.

[0015] The beneficial effects of this invention are as follows: 1) Torsion spring compensation ensures that the sidewall of the contour whetstone fits the side of the incised line, avoiding local scratches and effectively reducing surface roughness; 2) The high-frequency impact generated by ultrasonic vibration reduces grinding force and reduces surface plastic deformation; 3) The honing process has high quality and effectively improves processing efficiency.

[0023] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0024] like Figure 1-11 As shown, a self-deflecting conformal guided ultrasonic honing device for machining intaglio lines includes a self-deflecting conformal guided honing mechanism, an ultrasonic vibration mechanism, and a ball joint 22 mechanism. The self-deflecting conformal honing mechanism includes a honing housing 12, an expansion core 11, and multiple tilting blocks 9. The expansion core 11 is coaxial and axially slidably connected within the honing housing 12. The honing housing 12 has multiple grooves 7 evenly distributed circumferentially. The bottom ends of the multiple tilting blocks 9 are radially slidably connected to the multiple grooves 7 and are all in abutting and fitting with the expansion core 11. Each tilting block 9 has a sub-seat 3 above it, and a center bolt 4 is provided at the middle between each sub-seat 3 and the corresponding tilting block 9. The bottom of the center bolt 4 is flush with the top of the tilting block 9. The top of the fixed center bolt 4 is rotatably connected to the bottom surface of the sub-seat 3. A torsion spring 5 is fitted on the center bolt 4. Guide bolts 6 are provided at both ends of each sub-seat 3 and the corresponding inclined block 9. The bottom of the guide bolt 6 is fixed to the top surface of the inclined block 9. The bottom surface of the sub-seat 3 is provided with a T-slot 28 that matches the top of the guide bolt 6, and the diameter of the T-slot 28 is larger than the top diameter of the guide bolt 6 (to facilitate the sub-seat 3 to rotate at a small angle relative to the inclined block 9). A contoured whetstone 1 is fixed on each sub-seat 3. The ultrasonic vibration mechanism includes an ultrasonic housing and multiple flexible rods 10. A coaxially arranged amplitude transformer 16 and piezoelectric transducer 18 are fixed inside the ultrasonic housing. The front end of the ultrasonic housing is fixed to the rear end of the honing housing 12. The front ends of the multiple flexible rods 10 are respectively fixed to the rear ends of multiple sub-seats 3. The rear ends of the multiple flexible rods 10 extend into the ultrasonic housing and are evenly distributed and fixed to the front end of the amplitude transformer 16. The ball joint 22 mechanism includes a ball joint 22, the rear end of the ball joint 22 is adapted to a ball joint 22 seat, and the front end of the ball joint 22 is fixed to the rear end of the ultrasonic housing. The ball joint 22 mechanism, the ultrasonic vibration mechanism, and the self-deflecting conformal honing mechanism are all provided with through holes at their centers to facilitate the sliding of the mandrel 19 until it abuts against the center of the rear end face of the expansion core 11.

[0025] In use, the ball joint 22 is fixed to the honing machine, and the mandrel 19 on the honing machine is inserted into the through hole until it abuts against the rear end face of the expansion core 11. When the ultrasonic honing device enters the anterior line to be processed, the mandrel 19 of the honing machine is fed axially, causing the expansion core 11 to push the tilting block 9 to expand radially, which in turn drives the contouring oilstone 1 to expand radially. At the same time, the ball joint 22 mechanism achieves rotation, so that the contouring oilstone 1 is in continuous contact with the anterior line. Due to the spiral shape of the groove, the torsion spring 5 automatically twists according to the changes in cutting force and the wear of the honing stone 1, causing the honing stone 1 to adjust its angle in the tangential direction to maintain the optimal grinding state between the sidewall of the honing stone 1 and the sidewall of the groove. That is, when the honing stone 1 is subjected to a large tangential force at a certain position, the torsion spring 5 will twist at a certain angle to make the grinding surface of the honing stone 1 more matched with the direction of the tangential force, thereby reducing the fluctuation of the grinding force and improving the processing quality. After honing is completed, the torsion spring 5 returns to its original angle when there is no cutting force, preparing for the next honing operation. At the same time, the ultrasonic vibration energy is directionally transmitted, the piezoelectric transducer 18 generates vibration, the energy is focused by the amplitude transformer 16, and transmitted to the auxiliary seat 3 through the flexible rod 10, causing the honing stone 1 to vibrate and improving the honing processing quality.

[0026] In practice, one end of the torsion spring 5 is fixed to the sub-seat 3 and the other end is fixed to the honing housing 12, thus making the structure specific and standardized.

[0027] In practice, the bottom ends of multiple inclined blocks 9 are fitted with the groove 7 with a clearance, and the two ends of multiple inclined blocks 9 are respectively tightened by two sealing rings 8, realizing the sliding connection between the bottom ends of multiple inclined blocks 9 and the groove 7 (the sliding connection means that the two can slide against each other and are connected without separating), which is simple in structure and easy to implement.

[0028] In practice, each inclined block 9 has a positioning groove 27 at both ends for positioning the sealing ring 8, so that the sealing ring 8 can tighten the inclined block 9 and improve the stability of the overall structure.

[0029] In practice, the expansion core 11 is formed by multiple frustums connected in a straight line, and a cylinder is coaxially fixed at the front end of each frustum. The bottom surface of the tilting block 9 is a multi-segmented inclined surface that fits the frustum, and a clearance groove is provided between two adjacent inclined surfaces. The structure is specific and standardized, which makes the radial movement of the tilting block 9 more stable and further ensures the honing quality.

[0030] In specific implementation, the ultrasonic housing includes a cylindrical shell 17, a front cover 13, a rear cover 21, a vibrating disk 14, and a fixing ring plate 20. Through holes are located on the front cover 13 and the rear cover 21. A fixing hole is located at the center of the vibrating disk 14. The front end of the amplitude transformer 16 is a small-diameter end, and the rear end is a large-diameter end. The front end of the amplitude transformer 16 has external threads and is fitted with a fastening nut 15. The fixing hole of the vibrating disk 14 is fitted onto the front end of the amplitude transformer 16 and located behind the fastening nut 15. Multiple flexible rods 10 extend into the front cover 13 and are circumferentially and evenly fixed to the vibrating disk 14. The rear end of the amplitude transformer 16 is welded and fixed to the front end of the piezoelectric transducer 18. The rear end of the piezoelectric transducer 18 is fixed inside the cylindrical shell 17 by the fixing ring plate 20. The structure is specific and standardized, and the vibration of the amplitude transformer 16 is amplified through the vibrating disk 14.

[0031] In specific implementation, the honing housing 12 includes a stepped housing body, with an internal thread at the small-diameter end of the housing body, multiple grooves 7 located at the large-diameter end of the housing body, and a stepped front cover 13.

The specific structure for fixing the honing housing 12 to the ultrasonic shell is described.

[0032] In practice, the non-groove 7 part of the large diameter end of the housing body is equipped with multiple limiting blocks 26 to limit the torsion angle of the honing stone 1, so as to avoid excessive torsion angle causing mis-processing and affecting the honing quality.

[0033] In practice, the ball joint 22 seat includes a ball joint front cover 23 and a ball joint rear cover 25. The ball joint front cover 23 and the ball joint rear cover 25 are fixed by pre-tightening bolts 24. The structure is specific and standardized, making it easy to assemble and disassemble.
