Description

Technical Field

[0001] The present invention belongs to the technical field related to heavy-load grinding wheel production, and more specifically, particularly relates to a precision grinding processing device for heavy-load grinding wheel production. Background Art

[0002] Heavy-duty grinding wheels are tools used for grinding, cutting and polishing, usually composed of sand and a binder. Heavy-duty grinding wheels are widely used in different industries such as metal processing, glass processing, and ceramic processing for fine processing and surface treatment of workpieces. During the production process of heavy-duty grinding wheels, they are usually pressed and formed, and then the surface of the heavy-duty grinding wheels needs to be polished. However, the precision polishing device for heavy-duty grinding wheel production in the prior art has the following defects: In the prior art, when a precision grinding device for heavy-load grinding wheel production is grinding both end faces of a heavy-load grinding wheel, after grinding one end face of the heavy-load grinding wheel is finished, the heavy-load grinding wheel needs to be turned over manually. However, after the heavy-load grinding wheel is turned over, there is no positioning and guiding function for the heavy-load grinding wheel, so that the heavy-load grinding wheel needs to be positioned and clamped again, which is cumbersome to operate and inconvenient for grinding the heavy-load grinding wheel. In the prior art, a Chinese patent with application number CN202222884393.X discloses a processing equipment for the production of grinding wheel and abrasive tools, including a base, a top frame fixedly connected to the top of the base, hydraulic cylinders fixedly installed on both sides of the top of the top frame, the bottom ends of the two hydraulic cylinders pass through the top frame and are fixedly connected to a fixed plate, a servo motor is fixedly installed on the bottom end of the fixed plate, a grinding sheet is fixedly connected to the output end of the servo motor, the bottoms of both sides of the inner wall of the top frame are fixedly connected to vertical plates, the tops of the two vertical plates on the opposite sides are fixedly installed with reduction motors, the output end of the reduction motor is fixedly connected to a rotating shaft, and one end of the rotating shaft passes through the vertical plate and is fixedly connected to a mounting plate; this setting only squeezes and clamps the outer side of the heavy-load grinding wheel when turning over the heavy-load grinding wheel, however, some heavier heavy-load grinding wheels are easily displaced by turning over by clamping on the outer side alone, resulting in the heavy-load grinding wheel not being turned over in place, requiring manual auxiliary adjustment, which is cumbersome to operate and inconvenient for grinding the heavy-load grinding wheel; In the prior art, when a precision grinding processing device for heavy-load grinding wheel production is clamped and turned over, it is usually only possible to clamp and turn over a heavy-load grinding wheel with a fixed outer diameter. As a result, when heavy-load grinding wheels with different outer diameters are ground, a variety of flipping components need to be used to clamp and turn over the heavy-load grinding wheels, thereby requiring the replacement of a variety of flipping components, which is cumbersome to operate and inconvenient for the grinding of heavy-load grinding wheels.

[0033] Specific use of the present invention: The staff places the heavy-load grinding wheel on the upper end surface of the truncated table 11, and makes the inner side of the heavy-load grinding wheel located on the outer side of the round block 16; then the first electric telescopic rod 20 extends to drive the first movable plate 21 to move upward, and the first movable plate 21 moves upward to rotate through the two connecting plates 22 to push the two L-shaped blocks 19 to move radially outward, and the radial outward movement of the two L-shaped blocks 19 drives the two clamping blocks 17 and the two rubber plates 18 to move radially outward to squeeze, clamp and fix the inner side of the heavy-load grinding wheel. The two L-shaped blocks 19 move radially outward, and the movement of the L-shaped blocks 19 drives the first protrusions 24 to move. The first protrusions 24 move outward, and the contact surface between the first protrusions 24 and the second protrusions 26 is an inclined surface, thereby squeezing the paddle plate 25, so that the paddle plate 25 rotates around the rubber block 27 to avoid it. The rubber block 27 rotates to generate elastic force, so that after the first protrusions 24 and the second protrusions 26 are out of contact, the paddle plate 25 rotates and resets under the action of the elastic force of the rubber block 27; and the contact surface on the other side of the first protrusion 24 and the second protrusion 26 is a plane, so as to limit the radial inner movement of the L-shaped block 19, avoid the displacement of the two clamping blocks 17 and the two rubber plates 18, thereby avoid affecting the effect of clamping and fixing the inner side of the heavy-load grinding wheel, so as to facilitate the precision grinding of the heavy-load grinding wheel.

[0034] Then, the first hydraulic telescopic rod 14 extends to drive the grinding block 15 to move downward, so that the lower side of the grinding block 15 contacts one side of the upper end surface of the heavy-load grinding wheel, and the first hydraulic telescopic rod 14 stops; then, the second motor 23 starts to drive the circular table 11 to rotate, and the rotation of the circular table 11 drives the second annular plate 55 to slide in an annular manner in the workbench 10, so that the circular table 11 rotates smoothly, and the rotation of the circular table 11 drives the heavy-load grinding wheel to rotate through the two clamping blocks 17 and the circular block 16. The rotation of the heavy-load grinding wheel cooperates with the fixation of the grinding block 15 to perform precision grinding on one end surface of the heavy-load grinding wheel.

[0035] When one end face of the heavy-load grinding wheel needs to be turned over after grinding, first, the first hydraulic telescopic lever 14 contracts to drive the grinding block 15 to move upward, and the second motor 23 stops; then the two second electric telescopic rods 37 extend and respectively drive the two second moving plates 38 to move in opposite directions, the two second moving plates 38 move through the two second U-shaped frames 39 to drive the two first annular plates 40 to move in opposite directions, and the two first annular plates 40 move through the two rotating shafts 32 to drive the two first U-shaped frames 33 to move in opposite directions; the two first U-shaped frames 33 move in opposite directions, so that the lower ends of the two first U-shaped frames 33 are respectively at the two The two first U-shaped frames 33 move in opposite directions so that the opposite sides of the heavy-load grinding wheel enter the two first U-shaped frames 33 respectively, and then the outer side of the heavy-load grinding wheel squeezes and moves the plurality of rubber clamps 34, and the movement of the plurality of rubber clamps 34 compresses the plurality of compression springs 35 to generate elastic force, so that the plurality of rubber clamps 34 slide accordingly according to the outer diameter of the heavy-load grinding wheel, so that the heavy-load grinding wheels with different outer diameters can be clamped and fixed by the cooperation of the plurality of rubber clamps 34 and the plurality of compression springs 35. The two sliders 36 slide in the two second slide grooves 30 respectively, so that the sliders 36 contact the inclined surfaces of the two extrusion blocks 28, so that the two paddle plates 25 rotate around the two rubber blocks 27 on both sides, so that the second protrusions 26 are disengaged from the first protrusions 24 respectively, so that the L-shaped block 19 can move radially inward; then the first electric telescopic rod 20 contracts and drives the first movable plate 21 to move downward, and the first movable plate 21 moves downward to drive the two clamping blocks 17 to move radially inward through the two connecting plates 22, so as to loosen the inner side of the heavy-load grinding wheel.

[0036] Secondly, the two second hydraulic telescopic cylinders 48 extend and respectively drive the two housings 31 to move upward. The two housings 31 move upward and respectively drive the two first U-shaped frames 33 to move upward through the two rotating shafts 32. The two first U-shaped frames 33 move upward and drive the heavy-load grinding wheel to move upward, so that the heavy-load grinding wheel is out of contact with the round table 11. When the heavy-load grinding wheel moves upward for a certain distance, the two second hydraulic telescopic cylinders 48 stop, and then the two first motors 41 are started. The first motor 41 starts and drives the first gear 45 to rotate through the engagement of the second gear 42 with the first gear 45. The first gear 45 rotates and cooperates with the two slots 46 through the two clamping blocks 47 respectively, thereby driving the rotating shaft 32 to rotate. The rotation of the rotating shaft 32 drives the first U-shaped frame 33 to rotate. The rotation of the two first U-shaped frames 33 drives the heavy-load grinding wheel to turn over. Among them, the first gear 45 rotates to drive the annular member 44 to slide in the fixed plate 43, so that the first gear 45 is rotated and limited on the fixed plate 43, and then slides in the two slots 46 respectively through the two clamping blocks 47, so that the first gear 45 can rotate and always drive the rotating shaft 32 to rotate during the movement of the rotating shaft 32, so that the rotating shaft 32 and the first U-shaped frame 33 can be controlled by the driving component to rotate or move, which is conducive to clamping and turning the heavy-load grinding wheel, and improving the efficiency of precision grinding of the heavy-load grinding wheel. At the same time, the two shells 31 move upward and drive the two piston plates 50 to move upward through the two push rods 51 respectively. The two piston plates 50 move upward and squeeze the air in the two piston cylinders 49 into the two nozzles 53 respectively, so that the air in the two nozzles 53 is sprayed toward the upper end surface of the truncated table 11 through the two second inlet and outlet holes 54, so as to clean the upper end surface of the truncated table 11, and avoid the dust generated by the grinding of the heavy-load grinding wheel affecting the accuracy of re-clamping and fixing the heavy-load grinding wheel.
