Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of metal finishing, and particularly relates to a full-range polishing device for iron plates for bare wires and a polishing method thereof. BACKGROUND

[0002] The iron plate polisher for bare wires is a device specially used for surface treatment of an iron plate for winding bare wires, that is, by using the relative movement and friction between the abrasive disc and the surface of the iron plate, the abrasive grains on the surface of the abrasive disc and the surface of the high-speed rotating iron plate are in contact, cutting and friction, and with the continuous cutting and friction of the abrasive grains, burrs, rust and oxide layers on the surface of the iron plate are gradually removed, so that the surface smoothness and quality of the iron plate are improved, the bare wires are losslessly wound, and the service life of the iron plate is prolonged.

[0003] In the specific polishing process, the machine vibration of the device itself and the transmission of external environmental vibration will affect the polishing accuracy of the device, that is, the external vibration causes the instantaneous change of the contact pressure between the abrasive disc and the polishing object; when the abrasive disc is vibrated, the local area is subjected to a greater impact force, so that the friction force between the abrasive grains in the area and the surface of the workpiece increases, and the abrasion is intensified; in the area with smaller vibration, the friction force on the abrasive grains is relatively small, and the abrasion degree is relatively low.

[0004] At the same time, the vibration causes the abrasive disc to be repeatedly subjected to alternating stress, and the material of the abrasive disc is subjected to fatigue damage, especially at the weak parts such as the edge of the abrasive disc; the vibration causes the abrasive disc to be unbalanced when rotating at high speed, further intensifying the deformation of the abrasive disc and the decrease of the surface flatness, and then causing the protruding heights of the abrasive grains at different positions to be different, destroying the uniformity of the abrasive grains, producing scratches or depressions, and affecting the polishing quality.

[0005] In addition, the presence of solid particles changes the contact state between the abrasive disc and the object to be polished, at the particle dense area, the abrasive grains need to overcome greater resistance to polish, the contact stress is concentrated in these areas, so that the abrasion of the abrasive grains is intensified, according to the abrasion theory, the greater the friction force and impact force, the higher the abrasion rate of the abrasive grains, thereby causing the uneven abrasion of the abrasive grains, causing local overheating, and producing deformation or annealing.

[0006] When the abrasive disc is in contact with the object to be polished, the solid particles have a certain hardness and edges and corners, and will produce a certain impact force and extrusion force on the surface of the abrasive disc, the foregoing impact force or extrusion force will damage the bonding force between the abrasive grains and the binder, and then cause part of the abrasive grains to be loose or even fall off; at the same time, the extrusion action of the particles can also move the abrasive grains on the surface of the abrasive disc, thereby changing the distribution state of the abrasive grains and affecting the polishing quality.

[0054] The present application has the following beneficial effects:

[0055] 1. The present application solves the rigidity problem of traditional grinding disc whole polishing by segmenting the grinding disc, and the wear degree of the corresponding area grinding disc is reflected in real time through the axial jump of the vertical rod, that is, when the vertical rod jumps axially, the right-angle plate controls the carbon frame to move away from the U-face frame, at this time, the wedge plate in one-way rotation state engages the double-sided gear ring, the double-sided gear ring drives the sun gear to rotate through the central shaft device, the planetary gear is driven by the sun gear meshing to drive the plunger to move towards the spring pressure plate, until it contacts each spring pressure plate, which represents that the wear degree of the current area grinding disc reaches saturation, and the dust cover is reversed by the end plate to realize alternating polishing without stopping, and the worn grinding disc is replaced, reducing the deformation and annealing phenomenon caused by uneven grinding disc abrasive particles, improving the cutting quality before and after the grinding disc, and reducing the probability of uneven grinding disc abrasive particles, scratches and depressions.

[0056] 2. The one-way rotation of the wedge plate ensures that the angle of the double-sided gear ring does not change when the carbon frame falls back with the vertical rod, so that after a single axial jump of the vertical rod, the double-sided gear ring is stacked and stored in unit time, and in this process, the one-way engagement between the ring pipe, spring shovel and double-sided gear ring further ensures the single rotation of the double-sided gear ring, fully ensures the front and rear engagement continuity between the sun gear control planetary gear and the side gear, guarantees the linear correlation between the axial movement distance of the plunger and the single jump of the vertical rod, accurately expresses the wear limit state of the grinding disc in the cutting process, and helps to improve the consistency of uniform distribution of grinding disc abrasive particles before and after.

[0099] The specific process by which control unit 3 changes the overall position of grinding unit 4 and monitoring unit 5:

[0100] X-axis motion process:

[0101] First, under the stable support of the bracket 31, the panel 32 further defines the position of the stepper motor 33, and then the stepper motor 33 drives the screw 36 to rotate (the support 35 further ensures the stability of the screw 36's working environment).

[0102] Next, the rotating screw 36 drives the horizontal shaft seat 37 to reciprocate along the axis of the horizontal rail 34 under the further support and guidance of the horizontal rail 34.

[0103] Finally, the back adjustment plate 1 is controlled by the bridge deck column 38, which drives the telescopic cylinder 39 to move synchronously with the horizontal shaft seat 37.

[0104] Y-axis motion process:

[0105] Through the telescopic movement of the movable end of the telescopic cylinder 39 (in the specific implementation, when the compressed air enters the telescopic cylinder 39 through the air path system, the gas first enters the main chamber of the cylinder, and for the double-acting telescopic cylinder 39, the compressed air enters the rod cavity or the rodless cavity to push the piston to move in the opposite direction, realizing the extension or retraction of the piston rod), the control end plate 41 drives the dust cover 42 to reciprocate in the axial direction thereof, so as to cooperate with the aforementioned X-axis movement, realize the linkage of the X-axis and Y-axis, and ensure that the grinding unit 4 fully covers the end surface of the bare wire iron disc;

[0106] The specific working process of the grinding unit 4 (taking the symmetrically distributed grinding unit 4 as an example):

[0107] Firstly, the vertical rod 423 is controlled by the electric telescopic rod 412 (in the initial state, the electric telescopic rod 412 is in the retracted state), and the decorative plate 44 is driven to move in the axial direction of the dust cover 42 under the guidance of the sliding drawer 43 until the electric telescopic rod 412 reaches the maximum extension (at this time, the decorative plate 44 reaches the specified position);

[0108] Then, the bridge column 38 is controlled by the horizontal shaft seat 37, and the back adjusting plate 1 is driven to move along the axial direction of the screw rod 36 to the middle region of the screw rod 36. After that, the telescopic cylinder 39 is extended, the control end plate 41 drives the dust cover 42 to move towards the base frame 21 until the grinding piece 428 contacts the end surface of the bare wire iron disc (since the grinding unit 4 is symmetrically distributed inside the dust cover 42, at this time, only one end of the grinding unit 4 starts the grinding work, and the other end of the grinding unit 4 is still in the stopped state);

[0109] Finally, the relative movement between the grinding piece 428 and the bare wire iron disc is continuously generated by the high-speed rotation of the bare wire iron disc, so as to realize the grinding and processing of the impurities on the end surface of the bare wire iron disc by the grinding piece 428. After the grinding unit 4 works for a period of time (when the monitoring unit 5 alarms), the dust cover 42 is rotated by the end plate 41 (one hundred and eighty degrees, in the specific implementation, the rotation angle = 360 degrees / grinding unit 4 quantity, so as to realize the alternate non-stop grinding processing), and in the specific implementation, the dust cover 42 can be rotated by an external motor;

[0110] The limiting and releasing process of the limiting column 49 to the position of the U-face frame 421:

[0111] When the electric telescopic rod 412 is in extension, the vertical plate 411 drives the decorative plate 44 to move towards the axis of the dust cover 42, in this process, the single-sided rack 415 is separated from the single-sided rack 415 and is engaged through the engagement between the two, which drives the straight rod to drive the limiting column 49 to gradually move towards the U-shaped frame 421 under the guidance and support of the opening frame 46, until the limiting column 49 is in contact with the vertical section of the U-shaped frame 421 and maintains a certain interaction force (in specific implementation, the end of the limiting column 49 close to the U-shaped frame 421 is made of rubber material, and because the single-sided gears 48 of the same group are opposite in direction, the thread rotation direction of the inner wall of the limiting column 49 driven by the same group should be opposite, so as to ensure that the two limiting columns 49 of the same group move in the same direction);

[0112] Conversely, when the electric telescopic rod 412 is retracted, the limiting column 49 gradually releases the contact state between the limiting column 49 and the U-shaped frame 421;

[0113] When the grinding piece 428 contacts different solid particles in different regions or is subjected to different external vibrations:

[0114] Under the reverse action of the grinding piece 428, the grinding plate 427 (taking one of the segmented grinding plates 427 as an example) controls the vertical rod 423 to drive the gasket 424 to move away from the grinding piece 428, in this process, the axial displacement of the gasket 424 causes the compression of the return spring 426 to the face ring 425, and the vertical rod 423 as a whole moves a distance (unequal) to the horizontal section of the U-shaped frame 421.

[0115] Referring to Figure 9 , Figure 10 and Figure 11 , it can be seen that the monitoring unit 5 comprises: a monitoring chamber 51, which is installed in the horizontal section of the U-shaped frame 421 away from the decorative plate 44, and the position and number of the vertical rod 423 are one-to-one corresponding; a right-angle plate 52, which is installed on the outer wall of the vertical rod 423 away from the decorative plate 44, and the vertical section of the right-angle plate 52 is installed in the inner wall of the monitoring chamber 51; a sun rod 53, which is installed in the inner wall of the monitoring chamber 51; a ring tube 54, which is installed on one end of the outer wall of the sun rod 53; a spring shovel 55, which is installed on the outer wall of the ring tube 54 through the ear seat rotation cooperation, and the spring shovel 55 only supports one-way rotation within a certain angle; a double-sided gear ring 56, which is installed on the outer wall of the sun rod 53 through rotation cooperation, and the spring shovel 55 is one-way engaged with the inner gear ring of the double-sided gear ring 56;

[0116] Referring to Figure 10 and Figure 13It can be known that the vertical section of the right-angle plate 52 is connected and matched to install the carbon frame 511, the vertical sections of the carbon frame 511 are uniformly provided with the chain shaft 512 which is rotatably connected and matched, the wedge plate 513 is connected and matched to be installed at the middle position of the outer wall of the chain shaft 512, the torsion spring 514 is connected and matched to be installed between the wedge plate 513 and the carbon frame 511, the sheet plate 515 is connected and matched to be installed at one end of the outer wall of the chain shaft 512, the angle column 516 is uniformly provided at the outer wall of one side vertical section of the carbon frame 511, and the outer wall of the angle column 516 is tangent to one side end surface of the sheet plate 515;

[0117] Referring to Figure 10 and Figure 11 It can be known that the outer wall of one end of the double-sided gear ring 56 is connected and matched to install the middle shaft 521 which is rotatably connected and matched with the sun rod 53, the sun gear 522 which is rotatably connected and matched with the sun rod 53 is connected and matched to be installed at the side end surface of the middle shaft 521 away from the double-sided gear ring 56, the planet rod 523 which is plug-connected and matched to be installed in the inner wall of the monitoring chamber 51 is provided at one side of the sun rod 53, the planet wheel 524 which is engaged with the sun gear 522 is connected and matched to be installed at the outer wall of the planet rod 523, the wall plate 525 is slidably connected and matched to be installed in the inner wall of the monitoring chamber 51, the strut 526 is slidably connected and matched to be installed at the side end surface of the wall plate 525 close to the planet wheel 524, the edge bit gear 527 is connected and matched to be installed at the middle position of the side end surface of the edge bit gear 527 away from the gravity ball 528;

[0118] Referring to Figure 10 、 Figure 11 and Figure 14 It can be known that the outer end frame 531 is connected and matched to be installed at one end of the edge bit gear 527 away from the gravity ball 528, the thimble 532 is connected and matched to be installed at one end of the outer end frame 531 away from the edge bit gear 527, the T-shaped frame 533 is connected and matched to be installed in the inner wall of the monitoring chamber 51 away from the vertical rod 423, the electroplated plate 534 which is connected and matched to be installed is uniformly provided at the vertical section of the T-shaped frame 533 close to the side end surface of the edge bit gear 527, the mouth groove 535 is formed at the middle position of the electroplated plate 534, and the width of the mouth groove 535 is equal to the diameter of the thimble 532, the hinge plate 536 is connected and matched to be installed at the side end surface of the electroplated plate 534 away from the thimble 532 in a symmetrical manner, and the spring pressure plate 537 is rotatably connected and matched to be installed between the hinge plates 536.

[0119] The progressive energy storage monitoring process of the monitoring unit 5 to the single-time axial jump of the vertical rod 423 is as follows:

[0120] Firstly, when the vertical rod 423 makes a single axial jump, the right-angle plate 52 drives the carbon frame 511 to move away from the U-shaped frame 421. In this process, the wedge plates 513 at different positions constantly produce engagement with the outer gear ring of the double-sided gear ring 56 (at this time, the rotation of the wedge plate 513 is limited by the angle column 516, so when the contact between the lower wedge plate 513 and the double-sided gear ring 56 is rigidly released), and when the vertical rod 423 falls back, the right-angle plate 52 drives the carbon frame 511 to move to the initial position (at this time, the angle column 516 no longer limits the rotation of the wedge plate 513, that is, when the lower wedge plate 513 is no longer rigidly engaged with the outer gear ring of the double-sided gear ring 56, at the same time, the wedge plate 513 that has been disengaged from the double-sided gear ring 56 gradually returns to the initial state under the recovery action of the torsion spring 514), the double-sided gear ring 56 rotates in one direction by a certain angle (linearly related to the single axial jump of the vertical rod 423), that is, the double-sided gear ring 56 only expresses the single axial jump of the vertical rod 423 (towards the monitoring chamber 51) and does not express the backfall of the vertical rod 423;

[0121] Then, the sun gear 522 drives the planetary gear 524 to rotate through the central shaft device 521. In the initial state, the planetary gear 524 is engaged with the side toothed rack 527. At this time, the side toothed rack 527 controls the plunger 532 to move towards the T-shaped frame 533 through the outer end frame 531 (through the engagement and guidance between the support column 526 and the wall plate 525), until the plunger 532 lifts the spring pressure plates 537 in different areas;

[0122] In this process, the one-way rotating spring shovel 55 limits the double-sided gear ring 56 in the state of rotation (different from the rotation direction of the double-sided gear ring 56 under the action of the wedge plate 513). When the double-sided gear ring 56 has a tendency to rotate, the spring shovel 55 is rigidly engaged with the inner gear ring of the double-sided gear ring 56, and the ring pipe 54 does not rotate at all. Therefore, at this time, the double-sided gear ring 56 cannot rotate. When the wedge plate 513 drives the double-sided gear ring 56 to rotate, the spring shovel 55 is flipped by a certain angle (the spring shovel 55 can only rotate in one direction by a certain angle), and the rigid contact between the spring shovel 55 and the double-sided gear ring 56 is released. For details, refer to the one-way ratchet and pawl), so as to further ensure the single direction of the double-sided gear ring 56;

[0123] Finally, the axial jump of the vertical rod 423 in unit time is expressed by the total rotation angle of the double-sided gear ring 56, that is, by the planetary gear 524, the actual moving distance of the side toothed rack 527 is expressed, and the contact between the plunger 532 and all the spring pressure plates 537 is taken as the replacement signal of the grinding piece 428 (in specific implementation, the electroplated plate 534 is electrically connected with the external processing system, and when all the spring pressure plates 537 are under a certain pressure, the aforementioned electrical signal is converted into the retracting instruction of the telescopic cylinder 39 and the rotating instruction of the dust cover 42 by the external PLC control system, so as to realize the fine work of the fine grinding unit 4 without stopping);

[0124] At the same time, the wallboard 525 drives the edge bit rack 527 to move away from the planetary gear 524 (in actual implementation, the mouth slot 535 is sufficient to support the movement of the ejector pin 532 with the wallboard 525, avoiding the collision between the ejector pin 532 and the electroplated plate 534), the edge bit rack 527 drives the ejector pin 532 to move away from the spring pressure plate 537 area under the gravity of the gravity ball 528, until all the spring pressure plates 537 return to the initial position, and the wallboard 525 moves to the planetary gear 524 again (at this time, all the spring pressure plates 537 are not pressed again, that is, the two pressure changes of the spring pressure plate 537 are used as the movement signal of the wallboard 525, which can be analyzed and controlled by an external PLC control system), until they are engaged (in actual implementation, the wallboard 525 can be moved by an electric sliding block), which is beneficial to ensure the operation continuity of the monitoring unit 5;

[0125] For the replacement process of the worn-out grinding disc 428:

[0126] After the dust cover 42 rotates by a specified angle, the operator manually pulls the sliding drawer 43 (in the case of power failure), or the electric sliding block drives the sliding drawer 43 to move away from the axis of the dust cover 42, and pulls out the U-face frame 421 (at this time, the limiting column 49 has released the clamping limit of the U-face frame 421), and the grinding disc 428 is taken out as a whole. In actual use, the grinding disc 428 is clamped with the grinding plate 427, and the damaged grinding disc 428 can be directly replaced by pulling out and inserting.

[0127] The polishing method of the omnibearing polishing device for the bare wire iron disc provided by the application is as follows: first, the horizontal shaft seat 37 is driven to reciprocate on the end surface of the cross rail 34 under the driving of the stepping motor 33, and in this process, the telescopic cylinder 39 is matched to realize the two-axis linkage movement of the fine grinding unit 4 and the monitoring unit 5, so that the complete polishing of the end surface of the iron disc is realized.

[0128] Secondly, the extension of the electric telescopic rod 412 controls the vertical plate 411 to drive the decorative plate 44 to move to the axis area of the dust cover 42 until the grinding disc 428 contacts the iron disc, at this time, the telescopic chuck 24 clamps and limits the iron disc, and then the external motor drives the telescopic chuck 24 to rotate, so as to realize the relative movement cutting between the grinding disc 428 and the iron disc.

[0129] Third step: finally by external vibration caused by the radial impact between the grinding piece 428 and iron plate, and the contact impact between the solid particles on the surface of iron plate and grinding piece 428, promote the vertical rod 423 under the joint guidance of the sealing plate 422 and U face frame 421, control the right angle plate 52 to drive the carbon frame 511 to move to the end plate 41 direction, in this process, the wedge plate 513 unidirectional clamping double-sided gear ring 56, and make it unidirectional rotation, the sun gear 522 under the linkage of the central shaft device 521, promote the meshing between the planet wheel 524 and the side bit gear 527, until the contact between the ejector pin 532 and all spring pressure plate 537, at this time, the sum of the impact of the vertical rod 423 in the axial direction in unit time reaches the saturation value, the end plate 41 controls the dust cover 42 to turn to one hundred and eighty degrees.
