Technical Field

[0001] The invention relates to the technical field of grinding machine tools, in particular to a special tool for a rubber roller grinding machine and a use method thereof. Background Art

[0002] The special tool for the rubber roller grinding machine is a machine tool accessory or device designed for rubber roller grinding, which is designed to ensure that the rubber roller reaches the required accuracy and surface quality during the processing. With the continuous development of industrial technology, the application field of rubber rollers is becoming more and more extensive, and the requirements for the processing accuracy and surface quality of rubber rollers are becoming higher and higher. In the grinder, 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 sand grains gradually become blunt and have uneven wear, and the sand grains are also filled with cutting and sand grains. In this way, the working surface of the grinding wheel gradually loses its original shape and working function, and the surface finish of the workpiece after grinding deteriorates, so it must be regularly dressed.

[0003] In the prior art, there is a cutting device for grinding wheel processing with a protective mechanism, such as publication number CN219465923U, which includes a base, four corners at the bottom of the base are fixedly connected with gripping blocks, one of the corners at the top of the base is fixedly installed with a stopper, a steel plate is fixedly installed on one side of the top of the base, a steel block is fixedly connected to the top of the steel plate, a threaded hole is opened on the front of the steel block, a screw is threadedly connected to the threaded hole, one end of the screw is rotatably connected to a connecting block, flying sparks are blocked by the stopper to prevent the generated sparks from igniting objects on one side of the sparks, and the protective shell is pulled down to a certain position to prevent the residue from splashing when cutting the object to protect the safety of the user; a roller is installed to facilitate the movement of the cutting device for grinding wheel processing.

[0004] In order to solve the problem that the blade of the cutting equipment for grinding wheel processing lacks a protective structure, and when the blade is used to cut materials, the rotation of the blade may cause mechanical injuries to people, the prior art adopts the method of installing a protective shell 1, a protective shell 2 and a block to block the flying sparks;

[0005] However, in actual use, the grinding wheel will become blunt and lose its self-sharpening ability after a period of use, affecting the rounding effect. The protective range of the protective shell cannot be adjusted, which is not conducive to the safe storage of the grinding wheel when it is idle. Moreover, it is troublesome and inflexible to replace an accidentally broken grinding wheel.

The grinding wheel can be provided with multiple protections, and the integrated dresser can perform self-dressing of the grinding wheel without disassembly and dressing, and the manual dressing step is omitted. It can also achieve the alignment balance of the grinding wheel while meeting the installation requirements of the grinding wheel, thereby ensuring the stability of the installation and further improving the effect of the rubber roller grinding.

[0042] Embodiment 2, refer to the attached Figure 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 a connecting plate 51 is fixedly connected to one end of the convex column 511, and the connecting plate 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 a force-bearing handle 522 is fixedly connected to one end of the protruding column 521;

[0044] Reference Figure 3 and Figure 4As shown, the inner movable cover plate 5 is installed on the inner side of the front cover shield 41, and the protruding column 521 is installed through the central inner wall of the front cover convex cover 411, and the limit block 5211 added on the surface of the protruding column 521 is embedded in the adapted groove of the rotating ring 5212 to limit the installation of the protruding column 521; before or after the grinding wheel 3 is used to round the surface of the rubber roller, the hand grasps the force handle 522 connected to the outer end of the protruding column 521 and rotates it, and the protruding column 521 rotates with the force handle 522. The swivel 5212 rotates on the inner side of the limiting embedded groove 4110, which does not cause the displacement of the protruding column 521. It should be noted that the connecting plate 52 is integrally formed with the inner movable cover plate 5. When the connecting plate 52 rotates, the angle of the inner movable cover plate 5 is synchronously deflected. At the same time, the connecting plate 51 and the protruding column 511 connected to one side of the inner movable cover plate 5 move, and the protruding column 511 moves along the trajectory of the arc groove 410. The deflection angle of the inner movable cover plate 5 can be accurately adjusted through the scale on one side of the arc groove 410.

[0045] Specifically, when the grinding wheel 3 is idle, the inner movable cover plate 5 is rotated so that the boss 511 reaches the 0° position, thereby shielding the grinding wheel 3 and preventing the intrusion of external dust; when the grinding wheel 3 is in working state, the inner movable cover plate 5 is rotated so that the boss 511 reaches the 45° angle position, thereby shielding the upper part of the grinding wheel 3 and preventing the splashing of rounded chips 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, the boss 511 is rotated to the 105° angle position, at which 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 cause obstruction to the dressing operation.

[0046] Embodiment 3, refer to the attached Figure 1-14 , based on the second embodiment, in order to achieve the locking of the inner movable cover plate 5 after each deflection angle:

[0047] A gear 6 is arranged on the inner side of the force-bearing handle 522, and 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 on the lower side of the gear 6; the self-locking component includes a locking block 61 and a fixed slot plate 62, the upper outer surface of the locking block 61 is movably abutted against the teeth of the gear 6, the fixed slot plate 62 is fixedly mounted on the outer surface of the front cover shield 41, and an avoidance groove 1 620 and an avoidance groove 2 6200 are respectively opened on the inner wall of the fixed slot plate 62, and side blocks 611 are respectively fixedly mounted on the outer surfaces of both sides of the locking block 61, and an articulated seat 612 is fixedly mounted on the outer surface of the side block 611, and a force-bearing arm rod 613 is movably connected to the articulated seat 612; the lower end of the locking block 61 is connected to a telescopic sleeve rod 621 and a spring 622, and the spring 622 is slidably sleeved on the outside of the telescopic sleeve rod 621, and the lower end outer surfaces of the telescopic sleeve rod 621 and the spring 622 are respectively fixedly connected to the inner bottom surface of the fixed slot plate 62;

[0048] 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 pinch the force arm rod 613 with the tiger's mouth position of the other hand and pull the entire lock block 61 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 first avoidance groove 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 second avoidance groove 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 second avoidance groove 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. When the angle adjustment is completed, move the force arm rod 613 inward again. At this time, the second avoidance groove 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 between the tooth grooves of the gear 6 to complete the locking of the protruding column 521.

[0049] Embodiment 4, referring to the attached Figure 1-14 , on the basis of Embodiment 3, in order to achieve the balance of the grinding wheel 3 after assembly:

[0050] The grinding wheel balance mechanism includes a threaded block 72. The side view剖切 cross-section of the threaded block 72 is in a "匚"-shaped structure. The inner surface of the threaded block 72 is threadedly connected to the outer surface of the threaded portion 71. One side outer surface of the threaded block 72 is fixedly connected with a slider 721. The two ends of the outer surface of the slider 721 are respectively slidably connected to the preset sliding grooves on the inner wall of the protruding column 521. The other end of the slider 721 is fixedly connected with an abutting plate 722. The abutting plate 722 is in a "十"-shaped claw-like structure. The outer surface of the abutting plate 722 is movably connected to the outer surface of the grinding wheel 3;

[0051] When replacing the grinding wheel 3, first, insert a Phillips screwdriver into the Phillips slot at one end of the rotating rod 7 and use the rotating screwdriver to rotate the rotating rod 7. At this time, the threaded block 72 is subjected to the dual limiting effects of thread adaptation and the slider 721 and the sliding groove. The threaded block 72 drives the abutting plate 722 to move horizontally. When the abutting plate 722 moves away from the side of the grinding wheel 3, disassemble the connecting member between the front cover 41 and the rear cover 4, and then remove the grinding wheel 3, the inner movable cover plate 5 and the front cover 41 together;

[0052] On the contrary, when a new grinding wheel 3 is replaced for assembly, the grinding wheel 3 is placed between the inner sides of the inner movable cover plate 5. It should be noted that the inner movable cover plate 5 is deflected to a position of 105 degrees at this time, 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 22, and then the center of the grinding wheel 3 is aligned with the rotating shaft 22 for installation. Then, another set of connecting plates 52 is sleeved with one end of the rotating shaft 22. At this time, the protruding column 521 of the rotating shaft 22 is first sleeved. The outer side is adapted to be connected with the rotating ring 5212 provided on the rear cover shield 4, and then the grinding wheel 3 is pushed to the position of the protruding column 521. Subsequently, the rotating rod 7 is rotated so that the threaded block 72 drives the abutment plate 722 to move to one side of the grinding wheel 3. In this way, the position of the grinding wheel 3 is limited, and the phenomenon of throwing off the circle and falling off will not occur during the rounding operation. It should be noted that the moving abutment plate 722 at this time can not only play a certain role in forming and promoting the assembly of the grinding wheel 3, but also play a role in limiting the balance of the grinding wheel 3.

[0053] Embodiment 5, refer to the attached Figure 1-14 On the basis of the fourth embodiment, in order to realize the reversal of the rotating rod 7 after the threaded block 72 moves, the present embodiment adds an anti-rotation component:

[0054] An anti-rotation assembly is provided at one end of the rotating rod 7 away from the threaded block 72, and the anti-rotation assembly 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-bearing handle 522, and a soft partition plate 81 and a U-shaped elastic block 82 are fixedly installed on the inner ring surface of the inner sleeve ring 8, and the soft partition plates 81 are symmetrically distributed on both sides of the U-shaped elastic block 82, and the U-shaped elastic block 82 is a "U"-shaped structure, and a stretching elastic block 821 is fixedly connected to the inner side surface of the U-shaped elastic block 82, and the stretching elastic block 821 is a "yao"-shaped structure, and the arc surface of the U-shaped elastic block 82 is movably abutted against the outer surface of the rotating rod 7;

[0055] When the threaded block 72 reaches the final position, the cross screwdriver used to rotate the rotating rod 7 is pulled out of the cross slot. At this time, the additional anti-rotation component is used to ensure that the rotating rod 7 is not rotated by external force. Specifically, the soft partition plate 81 and the U-shaped elastic block 82 cooperate with each other, and the surfaces of both 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 inside provide a certain elastic force to the surface of the rotating rod 7, thereby ensuring that the rotating rod 7 will not rotate at will.

[0056] Embodiment 6, a method for using a special tool for a rubber roller grinding machine, comprising the following steps:

[0057] Step 1: Installation and connection: Assemble the main parts of the special tool, install the inner movable cover plate 5 on the inner side of the front cover shield 41, and assemble the protruding column 521 through the central inner wall of the front cover convex cover 411. The limit block 5211 added on the surface of the protruding column 521 is embedded in the groove adapted by the rotating ring 5212 to limit the installation of the protruding column 521. Before or after the grinding wheel 3 is used to round the surface of the rubber roller, the force-bearing handle 522 connected to the outer end of the protruding column 521 is grasped by hand and rotated. At this time, the protruding column 52 As the force-bearing handle 522 rotates, the rotating ring 5212 rotates inside the limiting embedded groove 4110, so that the protruding column 521 will not be displaced. It should be noted that the connecting plate 52 is integrally formed with the inner movable cover plate 5. When the connecting plate 52 rotates, the angle of the inner movable cover plate 5 is deflected synchronously. At the same time, the connecting plate 51 and the protruding column 511 connected to one side of the inner movable cover plate 5 move, and the protruding column 511 moves along the trajectory of the arc groove 410. The deflection angle 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 protection range: adjust the overall position of the connecting plate 52 as needed. 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 tiger's mouth of the other hand and pulls the locking block 61 as a whole 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 and enters the interior of the avoidance groove 2 6200. The rear locking block 61 is subjected to the reverse elastic force of the spring 622, and the force-bearing arm rods 613 on both sides thereof abut against the upper wall of the second 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, and 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, and the second 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.

[0059] Step 3: Grinding wheel balancing and anti-rotation: Install the grinding wheel balancing mechanism. When replacing a 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 the inner movable cover plate 5 is deflected to a position of 105 degrees at this time, which will not affect the placement of the grinding wheel 3. First, sleeve the connecting plate 52 on one side into the rotating shaft rod 22, and then align the center of the grinding wheel 3 with the rotating shaft rod 22 for installation. Then, another set of connecting plates 52 is sleeved with one end of the rotating shaft rod 22. At this time, the outer side of the protruding column 521 that is first sleeved into the rotating shaft rod 22 is adapted to be connected with the rotating ring 5212 provided on the rear cover shield 4, and then the grinding wheel 3 is pushed to the position of the protruding column 521. Then, the rotating rod 7 is rotated so that the threaded block 72 drives the abutting plate 722 to move to one side of the grinding wheel 3. In this way, the position of the grinding wheel 3 is limited, and the phenomenon of throwing off and falling off will not occur during the rounding operation.
