Description

Technical Field

[0001] This disclosure relates to the field of machining technology, and in particular to a grinding device. Background Technology

[0002] During the processing of metal parts, metal burrs are often formed on the surface of the metal parts, or metal protrusions or pits are caused on the surface during the cutting process, which will have a significant impact on subsequent processing and use.

[0003] In related technologies, manual or power tools are typically used to grind metal parts in order to improve the surface smoothness and machining accuracy of the metal parts.

[0004] However, for parts requiring high machining precision, both machine reprocessing and manual grinding may result in excessive grinding, rendering the parts unusable and indirectly increasing production costs. Furthermore, the grinding devices in related technologies can only grind parts with smooth surfaces; they cannot grind cylindrical parts. Summary of the Invention

[0016] The beneficial effects of the technical solutions provided in this disclosure include at least the following:

[0017] The grinding apparatus provided in this embodiment includes a base, a grinding assembly, and a clamping assembly. Two support rods of the grinding assembly are spaced apart on the base, and multiple grinding components are spaced apart between the two support rods. The U-shaped plates of adjacent grinding components are hinged together at both ends of an arc-shaped plate. When grinding a cylindrical part, the cylindrical part is placed on the grinding rollers of the multiple grinding components. Because adjacent grinding rollers are hinged together by arc-shaped plates, the multiple grinding rollers can freely swing to form an arc-shaped structure. This arc-shaped structure supports the cylindrical part, allowing all grinding rollers to contact the cylindrical part, maximizing the contact area between the grinding assembly and the cylindrical part, thereby improving the grinding effect. Furthermore, after the cylindrical part is placed on the arc-shaped structure, the clamping assembly's fixing frame can apply pressure to the cylindrical part on the grinding assembly, making the surface of the cylindrical part contact the grinding rollers more tightly. This way, when the first drive component controls the rotation of the grinding roller, the friction between the grinding roller and the cylindrical part is greater, making it easier to effectively grind the surface of the cylindrical part. This not only reduces the grinding difficulty of the cylindrical part, but also improves the processing accuracy and efficiency of the cylindrical part. Attached Figure Description

[0039] Figure 1 This is a front view of a polishing apparatus provided in an embodiment of this disclosure. Figure 2 This is a side view of a polishing apparatus provided in an embodiment of this disclosure. Figure 1 , 2 As shown, the polishing device includes: a base 10, a polishing component, and a clamping component.

[0040] like Figure 1 , 2 As shown, the grinding assembly includes: two support plates 21, multiple grinding components and multiple arc plates 23. Each grinding component includes a U-shaped plate 221, a grinding roller 222 and a first driving member 223. The two ends of the grinding roller 222 are rotatably connected to the opposite two surfaces of the U-shaped plate 221. The first driving member 223 is located on the U-shaped plate 221 and is used to drive the grinding roller 222 to rotate.

[0041] like Figure 1 , 2As shown, two support plates 21 are arranged at intervals on the base 10, and multiple grinding components are arranged at intervals between the two support plates 21. In the arrangement direction of the grinding components, the U-shaped plates 221 of the grinding components on both sides are connected to the two support plates 21 respectively. An arc plate 23 is provided between two adjacent grinding components, and the adjacent U-shaped plates 221 are respectively hinged to the two ends of the arc plate 23.

[0042] like Figure 1 , 2 As shown, the clamping assembly includes a first n-shaped plate 31 and a fixing frame 32. The first n-shaped plate 31 is located on the base 10, and the fixing frame 32 is located on the first n-shaped plate 31 and above the grinding assembly. The fixing frame 32 is configured to move in a direction close to or away from the grinding assembly.

[0043] The polishing device provided in this embodiment includes a base 10, a polishing assembly, and a clamping assembly. Two support rods 334 of the polishing assembly are spaced apart on the base 10, and a plurality of polishing components are also spaced apart between the two support rods 334. The U-shaped plates 221 of adjacent polishing components are hinged together by the two ends of an arc plate 23.

[0044] Figure 3 This is a state diagram of a grinding device grinding a cylindrical part according to an embodiment of this disclosure. Figure 3 As shown, when grinding a cylindrical part, the cylindrical part is placed on the grinding rollers 222 of multiple grinding components. Since adjacent grinding rollers 222 are hinged by arc-shaped plates 23, the multiple grinding rollers 222 can swing freely to form an arc-shaped structure. This arc-shaped structure supports the cylindrical part, allowing all grinding rollers 222 to contact the cylindrical part, and maximizing the contact area between the grinding components and the cylindrical part, thereby improving the grinding effect of the cylindrical part.

[0045] Meanwhile, after the cylindrical part is placed on the arc-shaped structure, the clamping assembly's fixing frame 32 can apply pressure to the cylindrical part on the grinding assembly, thereby allowing the surface of the cylindrical part to make closer contact with the grinding roller 222. This results in greater friction between the grinding roller 222 and the cylindrical part when the first driving component 223 controls the rotation of the grinding roller 222, making it easier to effectively grind the surface of the cylindrical part. This not only reduces the grinding difficulty of the cylindrical part but also improves the processing accuracy and efficiency of the cylindrical part.

[0046] Figure 4 yes Figure 1 A magnified view of point M is provided. (See attached image.) Figure 4 As shown, the grinding assembly also includes: a first fixed plate 24, a first transmission wheel 25, a second transmission wheel 26, and a transmission belt 27.

[0047] like Figure 4As shown, the first fixing plate 24 is located on the side where the straight edge of the U-shaped plate 221 is located. One end of the grinding roller 222 is movably inserted into the first fixing plate 24 through a rotating shaft, and at least part of the rotating shaft protrudes from the first fixing plate 24.

[0048] like Figure 4 As shown, the first drive member 223 and the grinding roller 222 are located on the same side of the U-shaped plate 221, and one end of the output shaft of the first drive member 223 passes through the first fixed plate 24, and at least a portion of the output shaft of the first drive member 223 protrudes from the first fixed plate 24.

[0049] like Figure 4 As shown, the first drive wheel 25 and the second drive wheel 26 are both located on the side of the U-shaped plate 221 away from the grinding roller 222. The first drive wheel 25 is coaxially sleeved on the outside of the rotating shaft, and the second drive wheel 26 is coaxially sleeved on the outside of the output shaft of the first drive member 223. The first drive wheel 25 and the second drive wheel 26 are connected by a drive belt 27.

[0050] For example, the first driving element 223 may be a motor, and the output shaft of the motor is coaxially connected to the second transmission wheel 26 so that the motor can drive the second transmission wheel 26 to rotate.

[0051] For example, the transmission belt 27 can be a belt with a large coefficient of friction between the belt and the transmission wheel, which can effectively transmit power from the second transmission wheel 26 to the first transmission wheel 25.

[0052] In the above implementation, after the cylindrical part is placed on each of the grinding rollers 222, the rotation of the first driving component 223 is controlled, thereby sequentially driving the second transmission wheel 26, the first transmission wheel 25, and the rotating shaft to rotate. The rotating shaft is coaxially connected to the grinding rollers 222, so the rotating shaft can drive the grinding rollers 222 to rotate together. In this way, by utilizing the rotation of the grinding rollers 222, the grinding operation on the cylindrical part can be performed more precisely.

[0053] Optionally, such as Figure 1 As shown, the polishing assembly also includes two support structures, which are arranged at intervals on the base 10, and multiple polishing components are sandwiched between the two support structures. The arrangement direction of the support structures is perpendicular to the arrangement direction of the support plate 21.

[0054] like Figure 4As shown, the support structure includes: a crossbeam 281, a first hydraulic cylinder 282, a second fixing plate 283, a second hydraulic cylinder 284, and a baffle 285. The first hydraulic cylinder 282 is located on the base 10, and the piston rod of the first hydraulic cylinder 282 is connected to the plate surface of the crossbeam 281. The second fixing plate 283 is located on the plate surface of the crossbeam 281 near the base 10. The cylinder of the second hydraulic cylinder 284 is connected to the second fixing plate 283, and the piston rod of the second hydraulic cylinder 284 is connected to the plate surface of the baffle 285. The plate surface of the baffle 285 has a positioning hole 286. The crossbeam 281 is located between the baffle 285 and the U-shaped plate 221.

[0055] like Figure 4 As shown, each grinding component also includes a positioning plate 224. One end of the positioning plate 224 is connected to the U-shaped plate 221, and the other end of the positioning plate 224 is used to insert into the positioning hole 286. The plate surface of the positioning plate 224 near the base 10 is located on the plate surface of the crossbeam 281 away from the base 10.

[0056] In this embodiment of the present disclosure, when it is necessary to control the locking of the grinding component and the support structure, the second hydraulic cylinder 284 can be driven to retract, so that the piston rod of the second hydraulic cylinder 284 pulls the baffle 285 to move towards the grinding roller 222 until the positioning hole 286 of the baffle 285 is fitted with the positioning plate 224 on the U-shaped plate 221, so that the positioning plate 224 of each U-shaped plate 221 is inserted into the positioning hole 286 of the baffle 285, thereby locking the positioning plate 224 on the crossbeam 281 to prevent the grinding roller 222 from swinging.

[0057] With the grinding components and support structure locked, such as Figure 1 As shown, the positioning plates 224 of each grinding component overlap the crossbeam 281, so that each grinding roller 222 is on the same horizontal plane. At this time, flat parts can be placed on the grinding components for grinding operations.

[0058] When it is necessary to unlock the grinding component from the support structure, the second hydraulic cylinder 284 is extended, causing the piston rod of the second hydraulic cylinder 284 to push the baffle 285 away from the grinding roller 222 until the positioning hole 286 of the baffle 285 separates from the positioning plate 224. At this time, as Figure 1 As shown, the positioning plate 224 overlaps the crossbeam 281, so that each grinding roller 222 is on the same horizontal plane.

[0059] With the grinding components and support structure unlocked, it is also necessary to control the retraction of the first hydraulic cylinder 282. That is, the first hydraulic cylinder 282 is used to pull the crossbeam 281 down towards the base 10 so that the positioning plate 224 no longer overlaps the crossbeam 281. In addition to the U-shaped plates 221 of the grinding components on both sides being connected to the two support plates 21 respectively, the grinding component in the middle will sag under the action of gravity. Therefore, the multiple grinding rollers 222 will form an arc structure to support the cylindrical parts, thereby making the grinding operation of the cylindrical parts more efficient.

[0060] Optionally, such as Figure 4 As shown, the support structure also includes: a first guide rod 287, a retaining ring 288, and a first guide cylinder 289. The first guide rod 287 is located between the baffle 285 and the second fixed plate 283. The first guide cylinder 289 is located on the plate surface of the crossbeam 281 near the base 10. The first guide rod 287 is inserted into the first guide cylinder 289, and both ends of the first guide rod 287 are connected to the baffle 285 and the retaining ring 288, respectively.

[0061] By setting a retaining ring 288 and a first guide rod 287 inserted in the retaining ring 288, the first guide rod 287 can only move within the range limited by the retaining ring 288. The first guide rod 287 is also connected to the baffle 285, so the movement path of the baffle 285 can also be limited, preventing the baffle 285 from tilting when it moves and thus failing to fit into the positioning plate 224.

[0062] Optionally, such as Figure 1 , 2 As shown, the grinding assembly also includes: a mounting base 41 and a T-shaped slider 42. The mounting base 41 and the support plate 21 correspond one-to-one, the T-shaped slider 42 and the mounting base 41 correspond one-to-one, the support plate 21 is connected to the corresponding mounting base 41, and the mounting base 41 is connected to the corresponding T-shaped slider 42.

[0063] like Figure 1 , 2 As shown, the surface of the base 10 has a T-shaped groove 11, which extends along the arrangement direction of the support plate 21, and the T-shaped slider 42 is slidably disposed in the T-shaped groove 11.

[0064] By fixing the support plate 21 to the mounting base 41 and fixing the mounting base 41 to the T-shaped slider 42, the support plate 21 can slide with the T-shaped slider 42 in the T-shaped groove 11, thereby adjusting the distance between the two support plates 21.

[0065] For cylindrical parts of different diameters, the relative spacing of the support plates 21 can be controlled to adjust the diameter of the arc-shaped structure formed by the grinding rollers 222, so that the arc-shaped structure can fit more closely with the cylindrical parts.

[0066] Optionally, such as Figure 2 As shown, the grinding assembly also includes two third fixing plates 29 and two third hydraulic cylinders 210. The two third fixing plates 29 are arranged at intervals on the base 10, and two support plates 21 are located between the two third fixing plates 29. A third hydraulic cylinder 210 is provided between the opposite support plate 21 and the third fixing plate 29. The two ends of the third hydraulic cylinder 210 are respectively connected to the corresponding support plate 21 and the third fixing plate 29.

[0067] By setting the third fixed plate 29 as the mounting base for the third hydraulic cylinder 210, the third hydraulic cylinder 210 can resist the extension and retraction of the third fixed plate 29, thereby pushing and pulling the two support plates 21 closer or further apart, so as to adjust the diameter of the arc-shaped structure formed by the grinding roller 222, and make the arc-shaped structure fit more closely with the cylindrical parts.

[0068] Optionally, such as Figure 2 As shown, the grinding assembly also includes a rib plate 211, which corresponds one-to-one with the support plate 21. The rib plate 211 is connected to the corresponding support plate 21 and the corresponding mounting base 41.

[0069] In this embodiment of the present disclosure, the support plate 21 and the mounting base 41 are vertically connected. By providing a rib plate 211 between the support plate 21 and the mounting base 41, the connection reliability between the support plate 21 and the mounting base 41 is enhanced, thereby improving the reliability of the grinding device.

[0070] Optionally, such as Figure 1 , 2 As shown, the fixing frame 32 includes: a fourth hydraulic cylinder 321, a second n-shaped plate 322, a third n-shaped plate 323, a fifth hydraulic cylinder 324, a fourth fixing plate 325, and a pressure roller 326.

[0071] like Figure 1 , 2 As shown, the fourth hydraulic cylinder 321 is located on the first n-shaped plate 31, and the piston rod of the fourth hydraulic cylinder 321 is connected to the second n-shaped plate 322.

[0072] In the above implementation, the extension and retraction of the fourth hydraulic cylinder 321 can control the lifting and lowering of the second n-shaped plate 322 relative to the first n-shaped plate 31.

[0073] For example, the fixing frame 32 may further include a second guide rod 341, one end of which is connected to the second n-shaped plate 322, and the other end of which passes through the first n-shaped plate 31. The second guide rod 341 can limit the movement path of the second n-shaped plate 322, preventing the second n-shaped plate 322 from tilting during movement.

[0074] like Figure 1 , 2As shown, the second n-shaped plate 322 is located on the side of the first n-shaped plate 31 near the base 10. The end face of the straight edge of the second n-shaped plate 322 is connected to the third n-shaped plate 323. The fifth hydraulic cylinder 324 is located on the third n-shaped plate 323, and the piston rod of the fifth hydraulic cylinder 324 is connected to the fourth fixed plate 325. The fourth fixed plate 325 is located on the side of the third n-shaped plate 323 near the base 10. The pressure roller 326 is located on the side of the fourth fixed plate 325 near the base 10, and the pressure roller 326 is rolled on the fourth fixed plate 325.

[0075] For example, the fixing frame 32 may further include a third guide rod 342, one end of which is connected to the fourth fixing plate 325, and the other end of which passes through the third n-shaped plate 323. The third guide rod 342 limits the movement path of the fourth fixing plate 325, preventing the fourth fixing plate 325 from tilting during movement.

[0076] In the above implementation, the third n-shaped plate 323 and the second n-shaped plate 322 are connected together, meaning the fourth hydraulic cylinder 321 can also control the third n-shaped plate 323 and the second n-shaped plate 322 to rise and fall together. The fifth hydraulic cylinder 324 is also connected to the fourth fixed plate 325, allowing the fifth hydraulic cylinder 324 to drive the pressure roller 326 on the fourth fixed plate 325 to rise and fall relative to the base 10. Therefore, by raising and lowering the fixed frame 32, the pressure roller 326 can be controlled to descend to the cylindrical part to squeeze it; by raising and lowering the fixed frame 32, the pressure roller 326 can also be controlled to rise, causing it to release the cylindrical part.

[0077] Optionally, such as Figure 1 As shown, the fixing frame 32 also includes two expansion structures, which are located on two opposite surfaces of the third n-shaped plate 323. The expansion structures are used to fix the cylindrical parts to be ground.

[0078] The tensioning structure is installed on the third n-shaped plate 323, and the fourth hydraulic cylinder 321 is installed on the first n-shaped plate 31. It can drive the second n-shaped plate 322 and the third n-shaped plate 323 to rise and fall. Therefore, it can drive the tensioning structure to rise and fall together, thereby adjusting the height of the tensioning structure so that the tensioning structure can be inserted from both ends of the cylindrical part to tension the cylindrical part and prevent the cylindrical part from slipping during the grinding process.

[0079] Figure 5 yes Figure 1 Provides a magnified view of N local locations. For example... Figure 5 As shown, the tensioning structure includes: a sixth hydraulic cylinder 327, a mounting plate 328, a second driving component 329, a first gear 330, a rotating column 331, a second gear 332, a cylinder 333, and a tensioning component.

[0080] like Figure 5As shown, the cylinder of the sixth hydraulic cylinder 327 is connected to the surface of the third n-shaped plate 323, the piston rod of the sixth hydraulic cylinder 327 is connected to the mounting plate 328, the mounting plate 328 is located between the pressure roller 326 and the sixth hydraulic cylinder 327, the second driving member 329 is located on the mounting plate 328, the output shaft of the second driving member 329 is coaxially connected to the first gear 330, one end of the rotating column 331 is movably inserted on the surface of the mounting plate 328 away from the sixth hydraulic cylinder 327, and the other end of the rotating column 331 is coaxially connected to the second gear 332, and the first gear 330 and the second gear 332 mesh.

[0081] like Figure 5 As shown, the cylinder 333 is located on the side of the second gear 332 away from the second gear 332, and one end of the cylinder 333 is coaxially connected to the second gear 332. The expansion member is located at the other end of the cylinder 333 and is used to be inserted into the inner hole of the cylindrical part to be ground.

[0082] In the above implementation, the second driving component 329 of the expansion structure can drive the first gear 330 and the second gear 332 to rotate. The second gear 332 can then drive the cylinder 333 to rotate, and an expansion component is also installed on the cylinder 333. In this way, when the expansion component expands the cylindrical part, the second driving component 329 drives the expansion component to rotate, thereby achieving the purpose of controlling the cylindrical part to rotate simultaneously during the grinding process, which can effectively improve the grinding efficiency of the cylindrical part.

[0083] For example, such as Figure 5 As shown, the tensioning structure may include a fourth guide rod 343, the first end of which is connected to the mounting plate 328, and the other end of which passes through the third n-shaped plate 323.

[0084] Optionally, such as Figure 5 As shown, the tensioning components include: a support rod 334, an anti-slip pad 335, a seventh hydraulic cylinder 336, a slider 337, a fixing block 338, and a push-pull rod 339.

[0085] like Figure 5 As shown, the end face of the cylinder 333 away from the mounting plate 328 is provided with multiple elongated grooves 3330, which are arranged circumferentially at intervals.

[0086] like Figure 5 As shown, each long groove 3330 is slidably provided with a fixing block 338, and a slider 337 is slidably provided in the cylinder 333, and each fixing plate is fixedly connected to the slider 337.

[0087] like Figure 5 As shown, the seventh hydraulic cylinder 336 is installed inside the cylinder 333. The cylinder barrel of the seventh hydraulic cylinder 336 is fixed on the end face of the second gear 332. The telescopic rod of the seventh hydraulic cylinder 336 is connected to the slider 337.

[0088] like Figure 5 As shown, one end of the support rod 334 is hinged to the end of the long groove 3330 away from the mounting plate 328 by a pin, and the other end of the support rod 334 is equipped with an anti-slip pad 335. One end of the push-pull rod 339 is hinged to the fixing block 338 by a pin, and the other end of the push-pull rod 339 is hinged to the middle of the support rod 334 by a pin.

[0089] In the above implementation, a seventh hydraulic cylinder 336 pushes a slider 337 to slide within the cylinder 333. This causes the slider 337 to move a fixed block 338 along the elongated groove 3330. The fixed block 338 then moves a push-pull rod 339, the other end of which is hinged to the middle of a support rod 334. When the push-pull rod 339 extends, it pushes the support rod 334 to unfold, causing the anti-slip pad 335 at the other end of the support rod 334 to press against the inner hole of the cylindrical part, thus tightening the cylindrical part. When the push-pull rod 339 retracts, it pulls the support rod 334 back, causing the anti-slip pad 335 at the other end of the support rod 334 to retract towards the central axis of the cylinder 333, thus preventing the anti-slip pad 335 from tightening the cylindrical part.

[0090] The working principle of the grinding device provided in this embodiment is as follows:

[0091] When grinding flat parts such as flat plates, the first drive unit 223 is activated. At this time, several grinding rollers 222 rotate at high speed under the drive of the first drive unit 223. The flat part is then placed with its grinding surface facing down on the multiple grinding rollers 222 distributed on the same horizontal plane, and the part is moved back and forth. This allows for grinding. During this process, the pressure roller 326 can be lowered using the fourth hydraulic cylinder 321 or the fifth hydraulic cylinder 324, pressing the part. This allows the grinding rollers 222 to better grind the part's surface. During this process, the support structure provides support for the multiple grinding rollers 222, ensuring that they are always flat and distributed on the same horizontal plane, preventing the grinding rollers 222 from shifting downwards under the weight of the part.

[0092] When grinding cylindrical parts, the two support structures are first separated from the positioning plates 224 at both ends of the grinding component. The specific process is as follows: First, the second hydraulic cylinder 284 is extended, causing its piston rod to push the baffle 285 away from the grinding rollers 222 until the positioning hole 286 of the baffle 285 separates from the positioning plate 224. At this point, the positioning plate 224 overlaps the crossbeam 281, ensuring that all grinding rollers 222 are on the same horizontal plane.

[0093] Then, the first hydraulic cylinder 282 is controlled to retract, that is, the first hydraulic cylinder 282 pulls the crossbeam 281 down towards the base 10, so that the positioning plate 224 no longer overlaps the crossbeam 281. In addition to the U-shaped plates 221 of the grinding components on both sides being connected to the two support plates 21 respectively, the grinding component in the middle will sag under the action of gravity. Therefore, the multiple grinding rollers 222 will form an arc structure to support the cylindrical parts, thereby making the grinding operation of the cylindrical parts more efficient.

[0094] Then, the fourth hydraulic cylinder 321 adjusts the cylinder 333 up and down to align its axis with the axis of the cylindrical part. Next, the sixth hydraulic cylinder 327 extends the cylinder 333 into the inner hole of the cylindrical part. At this time, the telescopic end of the seventh hydraulic cylinder 336 extends, pushing the support rod 334 through the push-pull rod 339. This causes several support rods 334 to simultaneously open towards the inner wall of the cylindrical part. When the anti-slip pads 335 at the ends of the support rods 334 are pressed against the inner wall of the cylindrical part, the seventh hydraulic cylinder 336 stops, and the second drive unit 329 is activated. During operation, the second drive unit 329 drives the second gear 3 through the first gear 330. When the second gear 332 rotates, it drives the cylindrical part to rotate synchronously through the support rod 334 that opens on the cylinder body 333. At this time, the first drive component 223 is activated. At this time, several grinding rollers 222 rotate at high speed under the drive of the first drive component 223. Since several grinding rollers 222 are hanging down and in contact with the outer wall of the cylindrical part, several grinding rollers 222 can simultaneously perform grinding work on the cylindrical part, thereby improving grinding efficiency. During this process, the pressure roller 326 can be lowered by the fifth hydraulic cylinder 324, and the cylindrical part is squeezed by the pressure roller 326, so that the grinding rollers 222 can better grind the surface of the part.
