Description

Technical Field

[0001] The invention belongs to the technical field of metal finishing, and in particular relates to an omnidirectional grinding device for an iron disc for a bare wire and a grinding method thereof. Background Art

[0002] Bare wire iron disc grinder: a device specially used for surface treatment of iron discs for winding bare wires. It uses the relative movement and friction between the grinding disc and the surface of the iron disc to make the abrasive grains on the surface of the grinding disc and the surface of the high-speed rotating iron disc come into contact, producing cutting and friction. With the continuous cutting and friction of the abrasive grains, the burrs, rust and oxide layer on the surface of the iron disc are gradually removed, thereby improving the surface finish and quality of the iron disc, achieving lossless winding of bare wires and extending the service life of the iron disc.

[0003] In the specific grinding process, the machine vibration of the equipment itself and the vibration transmission of the external environment will affect the grinding accuracy of the equipment. That is, the external vibration causes the contact pressure between the grinding disc and the grinding object to change instantly. When the grinding disc is vibrated, the local area is subjected to a large impact force, which increases the friction between the abrasive particles in this area and the surface of the workpiece, and the wear is aggravated. In the area with less vibration, the friction force on the abrasive particles is relatively small, and the degree of wear is relatively reduced.

[0004] At the same time, the vibration causes the grinding wheel to be repeatedly subjected to alternating stress, causing fatigue damage to the grinding wheel material, especially in weak areas such as the edge of the grinding wheel; the vibration causes the grinding wheel to be unbalanced when rotating at high speed, further aggravating the deformation of the grinding wheel and reducing the surface flatness, which in turn causes the protrusion height of the abrasive grains at different positions to be different, destroying the uniformity of the abrasive grains, causing scratches or depressions, and affecting the grinding quality;

[0005] In addition, the presence of solid particles will change the contact state between the grinding disc and the workpiece to be polished. In places where the particles are dense, the abrasive particles need to overcome greater resistance to perform polishing. The contact stress is concentrated in these areas, which intensifies the wear of the abrasive particles. According to wear theory, the greater the friction and impact force, the higher the wear rate of the abrasive particles, which leads to uneven wear of the abrasive particles, local overheating, deformation or annealing.

[0006] When the grinding wheel contacts the workpiece to be polished, the solid particles have a certain hardness and edges, which will produce a certain impact force and extrusion force on the surface of the grinding wheel. The aforementioned impact force or extrusion force will destroy the binding force between the abrasive particles and the binder, and then cause some abrasive particles to loosen or even fall off; at the same time, the extrusion effect of the particles may also push the abrasive particles to move on the surface of the grinding wheel, thereby changing the distribution state of the abrasive particles and affecting the grinding quality.

[0050] The method for uniformly grinding the surface of the bare wire iron disc adopts the above-mentioned all-round grinding device for the bare wire iron disc to provide precise grinding, and the specific steps are as follows:

[0051] S1: First, the screw is driven by the stepper motor to drive the horizontal shaft seat to reciprocate on the end surface of the horizontal rail. In this process, the telescopic movement of the telescopic cylinder is coordinated to complete the two-axis linkage movement of the fine grinding unit and the monitoring unit to achieve complete grinding of the end surface of the iron plate;

[0052] S2: Then, the electric telescopic rod is extended to control the vertical plate to drive the decorative plate to move toward the axis area of ​​the dust cover until the grinding disc contacts the iron plate. At this time, the iron plate is clamped and limited by the telescopic chuck, and then the telescopic chuck is driven to rotate by an external motor, so as to realize the relative motion cutting between the grinding disc and the iron plate;

[0053] S3: Finally, the radial impact between the grinding disc and the iron plate caused by external vibration, as well as the contact impact between the solid particles on the surface of the iron plate and the grinding disc, causes the vertical rod to control the right-angle frame to drive the carbon frame to move toward the end plate under the joint guidance of the sealing plate and the U-face frame. In this process, the wedge plate unidirectionally engages the double-sided gear ring and makes it rotate unidirectionally. Under the linkage action of the central shaft, the sun gear causes the planetary gear and the side rack to engage until the ejector contacts all the spring pressure plates. At this time, the sum of the impacts of the vertical rod in the direction of its axis per unit time reaches the saturation value, and the end plate controls the dust hood to turn 180 degrees.

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

[0055] 1. The present invention divides the grinding disc to flexibly handle the rigid disadvantage of the traditional integral grinding of the grinding disc, and the axial runout of the vertical rod can reflect the wear degree of the grinding disc in the corresponding area in real time, that is, when the vertical rod produces axial runout, the right-angle plate controls the carbon frame to move away from the U-face frame. At this time, the wedge plate in the unidirectional rotation state engages the double-sided gear ring, and the double-sided gear ring drives the sun gear to rotate through the central shaft device. Under the meshing action of the sun gear, the planetary gear prompts the edge rack to drive the ejector pin to move in the direction of the spring pressure plate until it contacts each spring pressure plate, which represents that the wear degree of the grinding disc in the current area has reached saturation, and the dust cover is reversed through the end plate to achieve alternating grinding without stopping the machine, and then the worn grinding disc is replaced, thereby reducing the deformation and annealing caused by uneven grinding grains of the grinding disc, while improving the cutting quality before and after the grinding disc, and to a certain extent reducing the probability of uneven grinding grains, scratches and depressions of the grinding disc.

[0056] 2. The present invention ensures that the angle of the double-sided gear ring remains unchanged when the carbon frame follows the vertical rod to fall back through the unidirectional rotation of the wedge plate, so that after a single axial jump of the vertical rod, all single jump distances within a unit time are stacked and stored through the unidirectional rotation of the double-sided gear ring. In this process, the unidirectional engagement between the annular tube and the spring shovel and the double-sided gear ring further ensures the singleness of the rotation of the double-sided gear ring, fully ensures that the sun gear controls the planetary gear, and the front and rear meshing continuity between the same edge racks, ensures the linear correlation between the axial movement distance of the ejector pin and the single jump of the vertical rod, accurately expresses the wear limit state of the grinding plate in the cutting process, and helps to improve the consistency of the uniform distribution of abrasive particles on the grinding plate.

[0097] The specific process of the control unit 3 changing the overall position of the fine grinding unit 4 and the monitoring unit 5 is as follows:

[0098] X-axis motion process:

[0099] First, the panel 32 is further limited to the position of the stepper motor 33 under the stable support of the bracket 31, and then the stepper motor 33 drives the screw 36 to rotate (the support 35 further ensures the stability of the working environment of the screw 36);

[0100] Then, the screw rod 36 in the rotating state drives the horizontal shaft seat 37 to reciprocate along the axis direction of the horizontal rail 34 under the further support and guidance of the horizontal rail 34;

[0101] Finally, the back adjustment plate 1 is controlled by the bridge deck column 38, driving the telescopic cylinder 39 to move synchronously with the horizontal shaft seat 37;

[0102] Y-axis movement process:

[0103] Through the telescopic movement of the movable end of the telescopic cylinder 39 (in specific implementation, when the compressed air enters the air inlet of the telescopic cylinder 39 through the air path system, the gas first enters the main chamber of the cylinder. For the double-acting telescopic cylinder 39, the compressed air enters the rod chamber or the rodless chamber, pushing the piston to move in the opposite direction, so as to achieve the extension or retraction of the piston rod), the control end plate 41 drives the dust cover 42 to reciprocate in the direction of its axis, so as to cooperate with the aforementioned X-axis movement to realize the linkage of the X-axis and the Y-axis, thereby ensuring the full coverage of the end face of the bare wire iron disc by the grinding end of the fine grinding unit 4;

[0104] The specific working process of the fine grinding unit 4 (taking the symmetrically distributed fine grinding unit 4 as an example):

[0105] First, the electric telescopic rod 412 controls the vertical rod 423 (in the initial state, the electric telescopic rod 412 is in the retracted state), driving the decorative plate 44 to move toward the axis direction of the dust cover 42 under the guidance of the slide 43 until the electric telescopic rod 412 reaches the maximum extension (at this time, the decorative plate 44 reaches the specified position);

[0106] Next, the bridge deck column 38 is controlled by the horizontal shaft seat 37 to drive the back adjustment plate 1 to move along the axis direction of the screw 36 to the middle area of ​​the screw 36. Thereafter, the telescopic cylinder 39 is extended to control the end plate 41 to drive the dust cover 42 to move toward the base frame 21 until the grinding disc 428 contacts the end surface of the bare wire iron disc (since the fine grinding units 4 are symmetrically distributed inside the dust cover 42, only the fine grinding unit 4 at one end starts the grinding operation at this time, and the fine grinding unit 4 at the other end is still in a shutdown state);

[0107] Finally, the bare wire iron disc in high-speed rotation continuously generates relative motion with the grinding disc 428, so as to realize the grinding processing of the impurities on the end surface of the bare wire iron disc by the grinding disc 428; after the current fine grinding unit 4 operates 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 specific implementation, the rotation angle = 360 degrees / number of fine grinding units 4, so as to realize alternating non-stop fine grinding processing), and in specific implementation, the dust cover 42 can be driven to rotate by an external motor;

[0108] The process of limiting and releasing the position of the U-face frame 421 by the limiting column 49:

[0109] When the electric telescopic rod 412 is extending, the vertical plate 411 drives the decorative plate 44 to move toward the axis of the dust cover 42. During this process, the single-sided rack 415 is separated from and then meshed with the single-sided rack 415. Through the meshing between the two, the straight rod drives the limiting column 49 to gradually move toward the U-face frame 421 under the guidance and support of the mouth frame 46, until the limiting column 49 contacts the vertical section of the U-face frame 421 and maintains a certain interaction force (in specific implementation, the end of the limiting column 49 close to the U-face frame 421 is made of rubber material, and because the single-sided gear 48 in the same group rotates in opposite directions, the inner wall thread rotation direction of the limiting column 49 in the same group affected by its drive should be set in opposite directions to ensure that the two limiting columns 49 in the same group move in the same direction);

[0110] On the contrary, when the electric telescopic rod 412 retracts, the limiting column 49 gradually releases the contact state with the U-surface frame 421;

[0111] When the grinding disc 428 contacts solid particles of different volumes in different regions or is subjected to different external vibrations:

[0112] Under the reverse action of the grinding disc 428, the grinding plate 427 (taking one of the segmented grinding plates 427 as an example) controls the vertical rod 423 to drive the washer 424 to move away from the grinding disc 428. During this process, the axial displacement of the washer 424 causes the return spring 426 to be compressed toward the face ring 425, and the vertical rod 423 as a whole moves a distance (not equal) toward the horizontal section of the U-face frame 421.

[0113] Reference Fig. 9 , Fig.10 and Fig.11 It can be seen that the monitoring unit 5 includes: a monitoring chamber 51, which is snap-fitted and installed on the end face of the horizontal section of the U-face frame 421 away from the decorative plate 44, and corresponds to the position and number of the vertical rod 423; a right-angle plate 52, which is snap-fitted and 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 snap-fitted and installed with the inner wall of the monitoring chamber 51; a solar rod 53, which is snap-fitted and installed between the inner walls of the monitoring chamber 51; a ring tube 54, which is snap-fitted and installed at one end of the outer wall of the solar rod 53; a spring shovel 55, which is rotatably installed on the outer wall of the ring tube 54 through an ear seat, and the spring shovel 55 only supports unidirectional rotation at a certain angle; a double-sided gear ring 56, which is rotatably installed on the outer wall of the solar rod 53, and the spring shovel 55 is unidirectionally meshed with the inner gear ring of the double-sided gear ring 56;

[0114] Reference Fig.10 and Fig.13 It can be seen that the vertical section of the right-angle plate 52 is snap-fitted with the carbon frame 511, and the chain shaft 512 is evenly arranged between the vertical sections of the carbon frame 511 and is rotatably mounted therewith, a wedge plate 513 is snap-fitted with the middle position of the outer wall of the chain shaft 512, and a torsion spring 514 is snap-fitted with the carbon frame 511, and a sheet 515 is snap-fitted with the outer wall of one end of the chain shaft 512, and a corner column 516 is evenly arranged on the outer wall of the vertical section of one side of the carbon frame 511, and the outer wall of the corner column 516 is tangent to the end face of one side of the sheet plate 515;

[0115] Reference Fig.10 and Fig.11 It can be known that a central axis device 521 which is rotatably mounted with the sun rod 53 is mounted on the outer wall of one end of the double-sided gear ring 56, a sun gear 522 which is rotatably mounted with the sun rod 53 is mounted on the end face of the central axis device 521 away from the double-sided gear ring 56, a planetary rod 523 which is plugged and mounted with the inner wall of the monitoring chamber 51 is arranged on one side of the sun rod 53, a planetary wheel 524 which meshes with the sun gear 522 is mounted on the outer wall of the planetary rod 523, a wall plate 525 is mounted on the inner wall of one side of the monitoring chamber 51 in a sliding manner, a pillar 526 is mounted on the end face of the wall plate 525 close to the planetary wheel 524 in a sliding manner, a side rack 527 is mounted on the side of the pillar 526 away from the wall plate 525, and a gravity ball 528 is mounted on the middle position of the end face of the side rack 527 close to the vertical rod 423;

[0116] Reference Fig.10 , Fig.11 and Fig.14 It can be known that an outer end frame 531 is snap-fitted to the end of the edge rack 527 away from the gravity ball 528, and a pin 532 is snap-fitted to the end of the outer end frame 531 away from the edge rack 527. A T-frame 533 is snap-fitted to the inner wall of the end of the monitoring chamber 51 away from the vertical rod 423. The end surface of the vertical section of the T-frame 533 close to the edge rack 527 is evenly provided with electroplating plates 534 snap-fitted to it. A groove 535 is provided in the middle of the electroplating plate 534, and the width of the groove 535 is equal to the diameter of the pin 532. A hinge plate 536 is symmetrically snap-fitted to the end surface of the electroplating plate 534 away from the pin 532, and a spring pressure plate 537 is rotatably installed between the hinge plates 536.

[0117] The monitoring unit 5 monitors the progressive energy storage process of a single axial runout of the vertical rod 423:

[0118] First, 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-face frame 421. During this process, the wedge plates 513 at different positions continuously engage with the outer gear ring of the double-sided gear ring 56 (at this time, the rotation of the wedge plate 513 is restricted by the corner column 516, so 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 corner column 516 is no longer The limiting plate 515 turns, that is, 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, which has been separated from the double-sided gear ring 56, gradually returns to its initial state under the restoring action of the torsion spring 514. The double-sided gear ring 56 rotates unidirectionally 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), but does not express the fall of the vertical rod 423.

[0119] Next, the sun gear 522 is controlled by the central shaft device 521 to drive the planetary gear 524 to rotate. In the initial state, the planetary gear 524 is meshed with the edge rack 527. At this time, the edge rack 527 controls the ejector pin 532 to move toward the T-joint frame 533 through the outer end frame 531 (through the engagement and guidance between the support 526 and the wall plate 525) until the ejector pin 532 lifts the spring pressure plate 537 in different areas.

[0120] During this process, the double-sided gear ring 56 in the rotating state (different from the rotating direction of the double-sided gear ring 56 under the action of the wedge plate 513) is limited by the unidirectionally rotating spring shovel 55 (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 annular tube 54 does not rotate at all. Therefore, the double-sided gear ring 56 cannot rotate at this time; when the wedge plate 513 drives the double-sided gear ring 56 to rotate, the spring shovel 55 flips over a certain angle (the spring shovel 55 can only rotate a certain angle in one direction), and the rigid contact between it and the double-sided gear ring 56 is released. For details, please refer to the unidirectional ratchet pawl), so as to further ensure the singleness of the double-sided gear ring 56.

[0121] Finally, the axial runout of the vertical rod 423 in a unit time is expressed by the sum of the rotation angles of the double-sided gear ring 56, that is, by the actual moving distance of the edge rack 527 driven by the planetary gear 524, and the ejector pin 532 contacts all the spring pressure plates 537 as a signal for replacing the grinding disc 428 (in specific implementation, the electroplating plate 534 is electrically connected to the external processing system, and when the spring pressure plates 537 all bear a certain pressure, the external PLC control system converts the aforementioned electrical signal into a retraction command of the telescopic cylinder 39 and a rotation command of the dust cover 42, thereby realizing the non-stop fine operation of the fine grinding unit 4);

[0122] At the same time, the wall plate 525 drives the edge rack 527 to move away from the planetary gear 524 (in specific implementation, the slot 535 is sufficient to support the ejector pin 532 to follow the "feeding" and "retracting" of the wall plate 525, avoiding collision and limitation between the ejector pin 532 and the electroplating plate 534), and the edge rack 527 drives the ejector pin 532 to leave 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 move toward the planetary gear 524 through the wall plate 525 again (at this time, all the spring pressure plates 537 are no longer subject to any external pressure, that is, the two pressure changes of the spring pressure plates 537 are used as the movement signal of the wall plate 525, which can be analyzed and controlled by the external PLC control system), until the two are meshed (in specific implementation, the wall plate 525 can be driven to move by the electric slider), which is conducive to ensuring the operation continuity of the monitoring unit 5;

[0123] Replacement process for worn grinding disc 428:

[0124] After the dust hood 42 rotates to a specified angle, the operator manually pulls the slide 43 (when the power is off), or drives the slide 43 to move away from the axis of the dust hood 42 through an electric slider, and the grinding disc 428 is taken out as a whole by plugging and unplugging the U-face frame 421 (at this time, the limit column 49 has released the clamping restriction on the U-face frame 421). During actual use, the grinding disc 428 is clamped with the grinding plate 427, and the damaged grinding disc 428 can be directly replaced by plugging and unplugging.

[0125] The present invention provides a method for grinding a bare wire iron plate with all-round grinding as follows: Step 1: First, the screw 36 is driven by the stepping motor 33 to drive the horizontal shaft seat 37 to reciprocate on the end surface of the horizontal rail 34. In this process, the two-axis linkage movement of the fine grinding unit 4 and the monitoring unit 5 is completed in cooperation with the telescopic movement of the telescopic cylinder 39, so as to achieve complete grinding of the end surface of the iron plate;

[0126] Step 2: Then, by extending the electric telescopic rod 412, the vertical plate 411 is controlled to drive the decorative plate 44 to move toward the axis area of ​​the dust cover 42 until the grinding disc 428 contacts the iron plate. At this time, the iron plate is clamped and limited by the telescopic chuck 24, and then the telescopic chuck 24 is driven to rotate by an external motor, so as to realize the relative motion cutting between the grinding disc 428 and the iron plate;

[0127] Step 3: Finally, the radial impact between the grinding disc 428 and the iron plate caused by external vibration, as well as the contact impact between the solid particles on the surface of the iron plate and the grinding disc 428, prompt the vertical rod 423 to control the right-angle frame to drive the carbon frame 511 to move toward the end plate 41 under the joint guidance of the sealing plate 422 and the U-face frame 421. In this process, the wedge plate 513 unidirectionally engages the double-sided gear ring 56 and makes it rotate unidirectionally. Under the linkage action of the central shaft device 521, the sun gear 522 prompts the planetary gear 524 to mesh with the edge rack 527 until the ejector pin 532 contacts all the spring pressure plates 537. At this time, the sum of the impacts of the vertical rod 423 in the axial direction per unit time reaches the saturation value, and the end plate 41 controls the dust cover 42 to turn 180 degrees.
