Description

Technical Field

[0001] The present invention relates to the technical field of grinding machine tools, and specifically to a special tool for a rubber roll rounding processing machine tool and a usage method thereof. Background Art

[0002] The special tool for a rubber roll rounding processing machine tool is a machine tool accessory or device designed specifically for rubber roll grinding processing, aiming to ensure that the rubber roll reaches the required precision and surface quality during the processing. With the continuous development of industrial technology, the application fields of rubber rolls are becoming increasingly extensive, and the requirements for the processing precision and surface quality of rubber rolls are also getting higher and higher; in a grinding machine, the correct dressing of the grinding wheel has a great influence on the surface finish of the workpiece after processing. After the grinding wheel has worked for a period of time, the abrasive grains gradually become dull, and there is uneven wear. The space between the abrasive grains is also filled with chips of cutting and abrasive grains. In this way, the working surface of the grinding wheel gradually loses its original shape and working function, resulting in a deterioration of the surface finish of the workpiece after grinding. Therefore, it must be dressed regularly.

[0003] In the prior art, for example, a cutting device for grinding wheel processing with a protection mechanism, with the publication number CN219465923U, includes a base. Four corners at the bottom of the base are fixedly connected with grounding blocks. One of the corners at the top of the base is fixedly installed with a baffle. One side at the top of the base is fixedly installed with a steel plate. The top of the steel plate is fixedly connected with a steel block. A threaded hole is opened on the front surface of the steel block. The threaded hole is threadedly connected with a screw rod. One end of the screw rod is rotatably connected with a connecting block. The baffle blocks the splashing sparks to prevent the generated sparks from igniting the objects on one side of the sparks. The second protective shell is pulled down to a certain position to prevent the residues from splashing when cutting an object, so as to protect the safety of the user; rollers are installed, and the rollers facilitate the movement of the cutting device for grinding wheel processing.

[0004] To solve the problem that the blade of the cutting device for grinding wheel processing lacks a protection structure, and there is a risk of mechanical injury to people when using the blade to cut materials, the prior art is to adopt the method of installing the first protective shell, the second protective shell and the baffle to block the splashing sparks for treatment;

[0005] However, in the actual use process, after the grinding wheel has been used for a period of time, it will become dull and lose its self-sharpening ability, affecting the rounding effect, and the shielding range of the protective shell cannot be adjusted, which is not conducive to the safe storage of the grinding wheel when it is idle; and when it is necessary to replace an accidentally broken grinding wheel, it is more troublesome and not flexible enough.

[0006] Therefore, the present invention proposes a special tool and its usage method for a rubber roll rounding machine tool, to solve the problems that the existing grinding wheel will become blunt and lose self-sharpening after a period of use, affecting the rounding effect, and the shielding range of the protective shell cannot be adjusted. It can provide multiple protections for the grinding wheel, integrate a dresser for self-trimming of the grinding wheel, without the need for disassembly and trimming, and also eliminates the manual trimming steps; and while meeting the installation of the grinding wheel, it can achieve the alignment balance of the grinding wheel, ensure the stability of the installation, and further improve the rubber roll rounding effect.

Specific embodiments

[0040] In order to clearly and completely describe the objectives, technical solutions of the present invention, and make the advantages more clearly understood, the following further details the embodiments of the present invention with reference to the accompanying drawings.

All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0041] Example 1, please refer to Figures 1-14The present invention provides a technical solution: a special tool for a rubber roller grinding machine, comprising a grinder 1 and a grinding wheel 3, wherein a sliding bracket 2 is slidably connected to the upper end of the grinder 1, a motor unit 21 is fixedly installed on the upper end of the sliding bracket 2, a rotating shaft 22 is fixedly connected to the output shaft of the motor unit 21, the outer surface of the rotating shaft 22 is detachably connected to the central inner surface of the grinding wheel 3, a rear cover shield 4 and a front cover shield 41 are respectively arranged on both sides of the grinding wheel 3, a grinding wheel dresser 23 is arranged on the upper end of the rear cover shield 4, an inner movable cover plate 5 is movably connected to the inner side of the rear cover shield 4 and the front cover shield 41, a front cover convex cover 411 is fixedly connected to the outer surface of the front cover shield 41, a rotating mechanism is rotatably connected to the inner side of the front cover convex cover 411, the rotating mechanism comprises a connecting plate 52, a rotating rod 7 is rotatably installed on the central inner surface of the connecting plate 52, a threaded portion 71 is arranged at one end of the rotating rod 7, a grinding wheel balancing mechanism is arranged outside the threaded portion 71, and a cross groove is opened at the other end of the rotating rod 7.

[0042] Embodiment 2, refer to the attached Figures 1-14 On the basis of the first embodiment, in order to realize the rotation of the inner movable cover plate 5, the adjustment of the protection range of the grinding wheel 3 is realized as follows:

[0043] The inner movable cover plate 5 and the connecting plate 52 are integrally formed into a plate-like structure. The connecting plates 52 are provided with two groups and are symmetrically distributed about the longitudinal center axis of the inner movable cover plate 5. The outer surface of one group of connecting plates 52 is rotatably connected to the inner surface of the front cover convex cover 411. The outer surface of the connecting plate 52 is fixedly connected with a protruding column 521. The outer surface of the protruding column 521 is fixedly installed with a limiting block 5211. The front cover convex cover 411 and the front cover shield 41 form a boss-like structure. The inner surface of the front cover convex cover 411 is provided with a limiting embedding groove 4110. The limiting embedding groove 4110 is provided with a limiting embedding groove 4111. A swivel 5212 is rotatably mounted on the inner surface of the swivel 5212, and a notch is preset on the inner surface of the swivel 5212 to fit with the limit block 5211; an arc groove 410 is provided on the inner wall of the front cover shield 41, and a convex column 511 is movably connected to the inner surface of the arc groove 410, and one end of the convex column 511 is fixedly connected to a connecting rod 51, and the connecting rod 51 is fixedly mounted on one side surface of the inner movable cover plate 5; the side view cross section of the connecting plate 52 and the protruding column 521 is a "convex"-shaped mechanism, and one end of the protruding column 521 is fixedly connected to a force-bearing handle 522;

[0044] Reference Figure 3 and Figure 4As shown, the inner movable cover plate 5 is installed inside the front cover shield 41. The protruding column 521 passes through the central inner wall of the front cover convex shield 411 for assembly. The limiting block 5211 added to the surface of the protruding column 521 is embedded in the matching notch of the rotating ring 5212 to limit the installation of the protruding column 521. Before or after the grinding wheel 3 rounds the surface of the rubber roller, the hand holds the force handle 522 connected to the outer end of the protruding column 521 and rotates. At this time, the protruding column 521 rotates with the force handle 522, and the rotating ring 5212 rotates inside the limiting groove 4110, so that the displacement of the protruding column 521 will not be caused. It should be noted that the connecting plate 52 and the inner movable cover plate 5 are integrally formed. When the connecting plate 52 rotates, the angle of the inner movable cover plate 5 deflects synchronously. At the same time, the connecting rod 51 and the convex column 511 on one side of the inner movable cover plate 5 move, and the convex column 511 moves along the track of the arc-shaped groove 410, and the angle of deflection of the inner movable cover plate 5 can be accurately adjusted through the scale on one side of the arc-shaped groove 410.

[0045] Specifically, when the grinding wheel 3 is idle, rotate the inner movable cover plate 5 so that the convex column 511 reaches the 0° position to shield the grinding wheel 3 and prevent the intrusion of external dust. When the grinding wheel 3 is in the working state, rotate the inner movable cover plate 5 so that the convex column 511 reaches the 45° angle position to shield the upper part of the grinding wheel 3 and block the splashing of grinding debris without affecting the normal operation of the grinding wheel 3. When the grinding wheel 3 needs to be dressed by the grinding wheel dresser 23, rotate the convex column 511 to the 105° angle position. At this time, the inner movable cover plate 5 is completely hidden between the rear cover shield 4 and the front cover shield 41, and will not block the dressing operation.

[0046] Embodiment 3, referring to the attached Figures 1-14 , on the basis of Embodiment 2, in order to lock the inner movable cover plate 5 after each deflection angle:

[0047] A gear 6 is arranged on the inner side of the force handle 522. The central inner surface of the gear 6 is fixedly connected to the outer surface of the protruding column 521, and a self-locking component is arranged below the gear 6. The self-locking component includes a lock block 61 and a fixed groove plate 62. The upper outer surface of the lock block 61 is movably abutted against the tooth space of the gear 6. The fixed groove plate 62 is fixedly installed on the outer surface of the front cover shield 41. Avoidance groove 620 and avoidance groove 6200 are respectively opened on the inner wall of the fixed groove plate 62. Side blocks 611 are respectively fixedly installed on the outer surfaces of both sides of the lock block 61. A hinge seat 612 is fixedly installed on the outer surface of the side block 611, and a force arm rod 613 is movably connected to the hinge seat 612. A telescopic sleeve rod 621 and a spring 622 are connected to the lower end of the lock block 61. The spring 622 is slidably sleeved on the outside of the telescopic sleeve rod 621. The lower outer surfaces of the telescopic sleeve rod 621 and the spring 622 are respectively fixedly connected to the inner bottom surface of the fixed groove plate 62.

[0048] Before adjusting the angle of the inner movable cover plate 5, the operator first unlocks the self-locking component, holds the force-bearing handle 522 with one hand, and pinches the force-bearing arm rod 613 with the base of the other hand and pulls the locking block 61 to move downward on the inner side of the fixed groove plate 62. At this time, the telescopic sleeve rod 621 and the spring 622 are elastically compressed by the upper pressure. When the side block 611 reaches the bottom surface of the avoidance groove 1 620, the two fingers pinching the force-bearing arm rod 613 are spread to both sides respectively. At this time, the force-bearing arm rod 613 rotates outward to enter the interior of the avoidance groove 2 6200, and then the locking block 61 is reversed by the spring 622. Due to the elastic force, the force-bearing arm rods 613 on both sides abut against the upper wall of the avoidance groove 6200, providing an upward thrust for the force-bearing arm rod 613 to stay. At the same time, the operator rotates the hand holding the force-bearing handle 522. When the inner movable cover plate 5 rotates to different states, the gear 6 always rotates with the protruding column 521. When the angle adjustment is completed, the force-bearing arm rod 613 is pushed inward again. At this time, the avoidance groove 6200 releases the restriction on the force-bearing arm rod 613. In this way, the locking block 61 is moved upward so that its upper end is inserted into the tooth groove of the gear 6 to complete the locking of the protruding column 521.

[0049] Embodiment 4, refer to the attached Figures 1-14 , based on the third embodiment, in order to achieve the balance of the grinding wheel 3 after assembly:

[0050] The grinding wheel balancing mechanism includes a threaded block 72, the side view cross section of the threaded block 72 is in the shape of a "匚" shape, the inner surface of the threaded block 72 is threadedly connected to the outer surface of the threaded portion 71, a slider 721 is fixedly connected to the outer surface of one side of the threaded block 72, the outer surfaces of both ends of the slider 721 are respectively slidably connected to the preset sliding grooves on the inner wall of the protruding column 521, and the other end of the slider 721 is fixedly connected to an abutment plate 722, the abutment plate 722 is in the shape of a "cross" claw, and the outer surface of the abutment plate 722 is movably connected to the outer surface of the grinding wheel 3;

[0051] When replacing the grinding wheel 3, first, insert a cross screwdriver into the cross groove at one end of the rotating rod 7, and use the screwdriver to rotate the rotating rod 7. At this time, the threaded block 72 is affected by the double limiting effects of the thread adaptation and the slider 721 and the slide groove. The threaded block 72 drives the abutment plate 722 to move in the horizontal direction. When the abutment plate 722 is away from one side of the grinding wheel 3, the connecting piece between the front cover shield 41 and the rear cover shield 4 is disassembled, and then the grinding wheel 3, the inner movable cover plate 5 and the front cover shield 41 can be removed together;

[0052] Conversely, when a new grinding wheel 3 is replaced and assembled, the grinding wheel 3 is placed between the inner sides of the inner movable cover plate 5. It should be noted that at this time, the inner movable cover plate 5 is deflected to a position of 105 degrees, which will not affect the placement of the grinding wheel 3. First, the connecting plate 52 on one side is sleeved into the rotating shaft rod 22, and then the central part of the grinding wheel 3 is aligned with the rotating shaft rod 22 for installation. Subsequently, the other set of connecting plate 52 is sleeved with one end of the rotating shaft rod 22. At this time, the convex column 521 on the outer side of the rotating shaft rod 22 that is first sleeved is adaptively connected to the rotating ring 5212 provided on the rear cover 4. Then, the grinding wheel 3 is pushed to the position of the convex column 521. Subsequently, the rotating rod 7 is rotated so that the threaded block 72 drives the abutting plate 722 to move towards the grinding wheel 3 side, so as to limit the position of the grinding wheel 3 and prevent the phenomenon of circular runout and falling off during the round grinding operation. It should be noted that the moving abutting plate 722 at this time can not only play a certain role in pushing the grinding wheel 3 during assembly, but also play a role in limiting and balancing the grinding wheel 3.

[0053] Embodiment 5. Referring to the attached Figures 1-14 , on the basis of Embodiment 4, in order to realize the reverse rotation of the rotating rod 7 after the threaded block 72 moves, an anti-rotation component is added in this embodiment:

[0054] An anti-rotation component is provided at one end of the rotating rod 7 away from the threaded block 72. The anti-rotation component includes an inner sleeve ring 8. The outer surface of the inner sleeve ring 8 is fixedly connected to the inner surface of the force-receiving handle 522. A flexible partition plate 81 and a U-shaped elastic block 82 are fixedly installed on the inner ring surface of the inner sleeve ring 8. The flexible partition plates 81 are symmetrically distributed on both sides of the U-shaped elastic block 82. The U-shaped elastic block 82 has a "U" shape structure. A tensile elastic block 821 is fixedly connected to the inner surface of the U-shaped elastic block 82. The tensile elastic block 821 has a "yao" shape structure. The arc surface of the U-shaped elastic block 82 is in movable abutment with the outer surface of the rotating rod 7.

[0055] After the threaded block 72 reaches the final position, the cross screwdriver used to rotate the rotating rod 7 is pulled out from the cross slot. At this time, the added anti-rotation component ensures that the rotating rod 7 does not rotate automatically under external force. Specifically, through the mutual cooperation of the flexible partition plate 81 and the U-shaped elastic block 82, their surfaces are in contact with the outside of the rotating rod 7. When the rotating rod 7 stops rotating, the U-shaped elastic block 82 and the tensile elastic block 821 connected to the inner side provide a certain elastic force to the surface of the rotating rod 7, so as to ensure that the rotating rod 7 does not rotate randomly.

[0056] Embodiment 6. A method for using a special tool for a rubber roller round grinding machine tool includes the following steps:

[0057] Step 1: Installation and Connection: Assemble the main components of the special tool. Install the inner movable cover plate 5 inside the front cover shield 41. The protruding column 521 passes through the central inner wall of the front cover convex shield 411 for assembly. The limiting block 5211 added on the surface of the protruding column 521 is embedded in the corresponding notch of the rotating ring 5212 to limit the installation of the protruding column 521. Before or after the grinding wheel 3 rounds the surface of the rubber roller, hold the force handle 522 connected to the outer end of the protruding column 521 by hand and rotate it. At this time, the protruding column 521 rotates with the force handle 522, and the rotating ring 5212 rotates inside the limiting groove 4110, so that the displacement of the protruding column 521 will not occur. It should be noted that the connecting plate 52 and the inner movable cover plate 5 are integrally formed. When the connecting plate 52 rotates, the angle of the inner movable cover plate 5 deflects synchronously. At the same time, the connecting rod 51 and the convex column 511 connected to one side of the inner movable cover plate 5 move. The convex column 511 moves along the track of the arc groove 410, and the angle of deflection of the inner movable cover plate 5 can be accurately adjusted through the scale on one side of the arc groove 410.

[0058] Step 2: Adjust the Shielding Range: Adjust the overall position of the connecting plate 52 as needed. Before the operator adjusts the angle of the inner movable cover plate 5, first unlock the self-locking component. Hold the force handle 522 with one hand, and use the tiger's mouth of the other hand to pinch the force arm rod 613 and pull the lock block 61 as a whole to move downward inside the fixed groove plate 62. At this time, the telescopic sleeve rod 621 and the spring 622 are elastically compressed under the upper pressure. When the side block 611 reaches the bottom surface of the avoidance groove 1 620, spread the two fingers pinching the force arm rod 613 to both sides. At this time, the force arm rod 613 rotates outward and enters the inside of the avoidance groove 2 6200. Subsequently, the lock block 61 is subjected to the reverse elastic force of the spring 622, and the force arm rods 613 on both sides thereof abut against the upper wall of the avoidance groove 2 6200, providing an upward thrust for the stay of the force arm rod 613. At the same time, the operator rotates the hand holding the force handle 522. When the inner movable cover plate 5 rotates to different states, the gear 6 always rotates with the protruding column 521. After the angle adjustment is completed, dial the force arm rod 613 inward again. At this time, the avoidance groove 2 6200 releases the restriction on the force arm rod 613. In this way, move the lock block 61 upward so that its upper end is inserted into the tooth groove of the gear 6 to complete the locking of the protruding column 521.

[0059] Step 3: Grinding wheel balancing and anti-rotation: Install the grinding wheel balancing mechanism. When replacing the new grinding wheel 3 for assembly, place the grinding wheel 3 between the inner sides of the inner movable cover plate 5. It should be noted that at this time, the inner movable cover plate 5 is deflected to the position of 105 degrees, so that it will not affect the placement of the grinding wheel 3. First, sleeved one side of the connecting plate 52 into the rotating shaft rod 22, then align the central part of the grinding wheel 3 with the rotating shaft rod 22 for installation. Subsequently, the other set of connecting plate 52 is sleeved with one end of the rotating shaft rod 22. At this time, the outer side of the protruding column 521 of the rotating shaft rod 22 sleeved first is adaptively connected with the rotating ring 5212 provided on the rear cover 4. Then, push the grinding wheel 3 to the position of the protruding column 521. Subsequently, rotate the rotating rod 7 so that the threaded block 72 drives the abutting plate 722 to move towards the grinding wheel 3 side, so as to keep the position of the grinding wheel 3 limited and prevent the phenomenon of circular runout and falling off during the circular grinding operation.

[0060] Step 4: Operation and processing: Install the assembled special tool on the rubber roller circular grinding machine tool and conduct debugging and inspection.

[0061] Step 5: Start the grinding machine 1 and start the processing process.

[0062] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
