when the honing tool works, the honing head is arranged on the honing machine and driven by the honing machine to rotate and reciprocate in the cylinder body to be processed, and other related structures (the structure that the honing head is matched with the honing machine) are not described (the prior art) because the scheme is only improved aiming at the honing head;
when the honing tool needs to work, firstly, a worker drives the driving rod 4 to act through the driving device arranged in the cylinder body 1 and drives the honing seats 2 to move in the radial direction of the cylinder body 1 in the direction of keeping away from each other through the driving rod 4 (when the driving rod 4 moves downwards, the honing seats 2 are driven to move in the direction of keeping away from each other, the elastic ring 6 is stretched at the moment, when the driving rod 4 moves upwards, the driving rod 4 does not apply an acting force on the honing seats 2 any more, at the moment, the honing seats 2 synchronously move in the direction of getting close to each other under the action of the elastic ring 6 matched with the honing seats 2), and then the honing tools 3 are synchronously driven to move, as shown in the attached drawing 2, the worker controls the outward movement distance of the honing seats 2 according to the diameter of the inner wall of the cylinder body to be polished, so that the honing tools 3 are abutted against the inner wall of the cylinder body, and then the honing tool is driven to rapidly rotate in the cylinder body through the honing tool (or the honing tool is synchronously driven to rapidly rotate in the inner seat of the cylinder body Reciprocating), thereby realizing the effect of polishing the inner wall of the cylinder body;
as shown in the attached figure 1, a pointer rod 23 is integrally arranged at the upper end part of the honing seat 2, and scales matched with the pointer rod 23 are arranged on the upper end surface of the barrel body 1, so that a worker can judge and control the moving distances of a plurality of honing seats 2 (to enable the honing seats to be matched with the inner wall of a cylinder body to be polished) according to the matching of the pointer rod 23 and the scales;
after the emery stick 3 is used for a long time and is abraded, if a worker controls the moving distance of the emery stick 3 again according to the matched pointer rod 23 and the scale, the emery stick 3 is not in contact with the inner wall of the cylinder body (or the pressure between the emery stick and the cylinder body does not reach the processing requirement) due to loss when the emery stick 3 moves to the corresponding scale position indicated by the pointer rod 23, and if the position of the emery stick 3 is not corrected, the grinding precision is reduced, and the processed product is unqualified and even scrapped;
the staff need not to demolish 3 sand bars that produce the loss this moment and can realize proofreading and correct 3 positions of sand bar, and concrete operation is as follows:
as shown in fig. 6, in order to maintain the driving rod 4 at the initial position (at this time, the plurality of sand bars 3 are also at the initial position synchronously), at this time, the worker controls the driving rod 4 to move upwards in the cylinder 1 through the driving device, the driving device is driven to move through the adjusting device arranged in the cylinder 1 in the process of moving upwards the driving rod 4, and the sand bars 3 are driven to move along the honing seats 2 corresponding to the driving device along with the movement of the driving device (i.e., the plurality of sand bars 3 are driven to move outwards along the honing seats 2 corresponding to the driving device, and the moving distance is determined according to the loss caused by the abrasion of the sand bars 3), so as to compensate the loss caused by the abrasion of the sand bars 3, compared with the conventional method of fixedly installing the sand bars 3 and the honing seats 2 (when the sand bars 3 are abraded, only the whole sand bars 3 can be replaced, resources are wasted, and the sand bars 3 need to be disassembled, the workload of workers is increased), not only the usage amount of the sand strip 3 is reduced (being beneficial to economical cost), but also frequent disassembly and assembly of the sand strip 3 are avoided (reducing the workload of the workers).
when the driving device drives the driving rod 4 to move downwards in the cylinder body 1, the honing seats 2 are driven to synchronously move outwards along the radial direction of the cylinder body 1 towards the direction away from each other through the inclined surface action between the inclined block 7 and the inclined plate 8, and the sand bars 3 are further driven to move towards the direction close to the inner wall of the cylinder body so as to be abutted against the inner wall of the cylinder body to be processed;
when the worker drives the driving rod 4 to move downwards through the driving device, the worker refers to the scale arranged on the upper end surface of the cylinder body 1 according to the honing amount of the cylinder body to be processed, and controls the downward movement distance of the driving rod 4 through the pointing direction of the pointer rod 23, so that the outward movement distance of the plurality of sand bars 3 can meet the honing amount of the cylinder body to be processed;
as shown in fig. 6, drive arrangement installs in barrel 1 and threaded rod 9 with the axle center setting with it for rotating, threaded rod 9 and actuating lever 4 are installed with axle center screw-thread fit, when carrying out feeding of a plurality of sand bars 3, the staff can realize driving actuating lever 4 and carry out vertical movement in barrel 1 through rotating threaded rod 9 and then (be equipped with in barrel 1 with the 4 sliding fit's of actuating lever gag lever post of 4, two gag lever posts install with the 4 vertical sliding fit in axial both sides of actuating lever respectively, be used for realizing spacing to actuating lever 4, make and to drive actuating lever 4 and reciprocate when rotating threaded rod 9.
when the honing machine works, a worker drives the driving rod 4 to move upwards from an initial position by rotating the threaded rod 9, then drives the plurality of gears 13 to synchronously rotate by the adjusting device, and drives the mounting seat 10 to slide relative to the honing seat 2 by the aid of the one-way shaft 12 and the reciprocating screw rod which are in axial sliding fit along with rotation of the gears 13, so that the sand bars 3 which generate loss are driven to move outwards (the sand bars 3 only need to move a small distance due to the fact that the adjusting distance is small, and the worker needs to judge according to the loss of the sand bars 3);
the one-way shaft 12 is adopted, so that after the position of the sand bars 3 is adjusted, a worker reversely rotates the threaded rod 9 to drive the driving rod 4 to move downwards, and the adjusting device cannot drive the reciprocating screw to rotate (due to the one-way transmission characteristic of the one-way shaft 12) through the gear 13 and the one-way shaft 12 in the downward movement process of the driving rod 4, so that the reciprocating screw is positioned at the previous adjusting position (and the sand bars 3 are positioned at the adjusted position);
note: after the sand bars 3 are corrected for many times, the remaining amount of the sand bars 3 is very small and cannot be used continuously, at this time, the sand bars 3 need to be replaced, but the position of the mounting seat 10 is no longer at the initial position (after the sand bars 3 are corrected for many times, the mounting seat 10 is not at the initial position), so the mounting seat 10 needs to be reset at this time, a worker only needs to rotate the threaded rod 9 and drive the driving rod 4 to move upwards to a certain distance (at this time, the mounting seat 10 moves outwards from the initial position to the farthest distance), at this time, the adjusting device starts to drive the mounting seat 10 to move towards the initial position through the gear 13, the one-way shaft 12 and the reciprocating screw rod 11 so as to move to the initial position (completing the resetting of the mounting seat 10), and then new sand bars 3 can be installed.
when the correction of the position of the sand bar 3 is completed and the threaded rod 9 is rotated reversely, so that the driving rod 4 moves downwards, in order to reset the end face gear ring 14 (to make it rotate again to the initial position and make the arc plate 15 return to the position corresponding to the convex plate 16), a torsion spring 17 is arranged coaxially on one side of the gear 13, which is away from the end face gear ring 14, and the other end of the torsion spring 17 is installed in the cylinder 1, when the driving rod 4 moves downwards, the convex plate 16 and the arc plate 15 which are mutually butted together are separated (namely, the convex plate 16 does not apply extrusion force to the arc plate 15 any more), then along with the downward movement of the convex plate 16, the gear 13 starts to rotate reversely under the action of the torsion spring 17 (at this time, the reciprocating screw cannot be driven to rotate by the one-way shaft 12), and along with the reverse rotation of the gear 13, the end face gear ring 14 is synchronously driven to rotate reversely, so that the end face gear ring 14 returns to the initial position (the reset is completed, so that the convex plate 16 and the arc-shaped plate 15 return to the original corresponding positions);
note: when the lower terminal surface position of arc 15 and the contact of 16 up end positions of flange, terminal surface ring gear 14 reached the biggest turned angle this moment, set for this moment, just realize reseing mount pad 10 (namely, make mount pad 10 move to initial position again by the extreme position department that it can move to, can carry out the installation of new sand strip 3), namely, when proofreading sand strip 3 position at ordinary times, only need drive terminal surface ring gear 14 and rotate the correction that can realize the sand strip 3 position a little angle.
an L-shaped rod 18 is vertically and slidably mounted on the circumferential surface of a driving rod 4, a positioning hole 20 matched with the L-shaped rod 18 is formed in the lower end face of an inclined block 7, initially, the upper end face of the L-shaped rod 18 is not inserted into the positioning hole 20, when the position of a sand stick 3 needs to be corrected, the driving rod 4 moves upwards to drive the L-shaped rod 18 to move upwards synchronously, initial non-contact between an arc plate 15 and a convex plate 16 is set (only vertical non-contact is achieved, but the vertical projections of the arc faces of the arc plates are still consistent), along with the upward movement of the driving rod 4, when the upper end face of the L-shaped rod 18 is inserted into the positioning hole 20 (at this time, the effect of positioning a plurality of honing seats 2 is achieved, the plurality of honing seats 2 are prevented from moving along the radial direction of a barrel body 1), the arc face of the convex plate 16 is in contact with the arc face of the arc plate 15, and along with the continuous upward movement of the driving rod 4 after the positioning, the adjustment of the position of the sand stick 3 is achieved, because the telescopic spring 19 is connected between the L-shaped rod 18 and the driving rod 4, the telescopic spring 19 is continuously compressed along with the upward movement of the driving rod 4, but the L-shaped rod 18 still realizes the positioning effect on the honing seat 2;
the driving rod 4 moves downwards to drive the honing seats 2 to move along the radial direction of the cylinder body 1, so that the adjustment of the feeding amount is completed (the adjustment of the feeding amount and the matching with the inner wall of the processed cylinder body are met), and the downward movement of the driving rod 4 is not hindered by the arrangement of the L-shaped rods 18.
Embodiment 6, on the basis of embodiment 5, as shown in fig. 6, in order to enable the honing head to rotate the end face ring gear 14 during the processing of the inner wall of the cylinder (the honing head may rotate at a high speed under the action of the honing machine and may move back and forth in the cylinder, and may generate a large shaking), at this time, the end face ring gear 14 needs to be positioned, so as to avoid the change of the position of the emery stick 3 relative to the honing seat 2 caused by the rotation during the high-speed selection of the honing head, as shown in fig. 7, locking holes 21 are respectively provided on two axial sides of the end face ring gear 14, and locking rods 22 matching with the locking holes 21 are integrally provided on two axial sides of the upper end face of the driving rod 4, and initially, the locking rods 22 are inserted into the locking holes 21 (to lock the end face ring gear 14);
when the feeding of a plurality of honing seats 2 needs to be adjusted, the driving rod 4 is controlled to move downwards, the locking rod 22 is synchronously moved downwards relative to the locking hole 21 (the locking hole 21 is set to be a hole which penetrates through the locking hole up and down), when the honing seats are adjusted in place and cylinder body processing is started, the end face gear ring 14 is still in a locked state under the action of the locking rod 22 and the locking hole 21 which are matched with each other (the end face gear ring 14 cannot rotate due to shaking generated by high-speed rotation of the honing head), when the position of the sand bar 3 needs to be corrected, the driving rod 4 is controlled to move upwards, the locking rod 22 is also set to be just withdrawn from the locking hole 21 (the locking of the end face gear ring 14 is released) when the arc face of the convex plate 16 is contacted with the arc face of the arc plate 15, and then the correction process of the position of the sand bar 3 can be realized;
after the position of the sand bar 3 is corrected, the driving rod 4 is controlled to move downwards, the end face gear ring 14 is reset synchronously under the matching action of the torsion spring 17 and the gear 13 along with the downward movement of the driving rod 4, so that when the end face gear ring 14 rotates to the initial position, the locking hole 21 arranged on the end face gear ring 14 just corresponds to the locking rod 22 again, the lower end of the locking rod 22 moves to be in contact with the upper port of the locking hole 21 (at the moment, the driving rod 4 does not move downwards to the initial position), and then the locking rod 22 is driven to be inserted into the locking hole 21 along with the continuous downward movement of the driving rod 4 by a corresponding distance (moves to the initial position), so that the end face gear ring 14 is locked.
The above description is only for the purpose of illustrating the present invention, and it should be understood that the present invention is not limited to the above embodiments, and various modifications conforming to the spirit of the present invention are within the scope of the present invention.
