[0039] Figure 1 It is a front view of a grinding device provided in an embodiment of the present disclosure. Figure 2 is a side view of a grinding device provided by an embodiment of the present disclosure. Figure 1 , 2 As shown, the grinding device includes: a base 10, a grinding 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, both ends of the grinding roller 222 are respectively rotatably connected to the two opposite plate surfaces of the U-shaped plate 221, and 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 a plurality of 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 assemblies on both sides are respectively connected to the two support plates 21, and an arc-shaped 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-shaped plates 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, the fixing frame 32 is located on the first n-shaped plate 31 and above the grinding assembly, and the fixing frame 32 is configured to move in a direction close to or away from the grinding assembly.

[0043] The grinding device provided by the embodiment of the present disclosure includes a base 10, a grinding assembly and a clamping assembly. Two support rods 334 of the grinding assembly are arranged at intervals on the base 10, and a plurality of grinding components arranged at intervals are arranged between the two support rods 334, and the U-shaped plates 221 of adjacent grinding components are hinged at both ends of the arc plate 23.

[0044] Figure 3 1 is a state diagram of a grinding device grinding a cylindrical part provided by an embodiment of the present disclosure. Figure 3 As shown, when the cylindrical part needs to be polished, the cylindrical part is placed on the polishing rollers 222 of the polishing components. Since the adjacent polishing rollers 222 are hinged by arc plates 23, the multiple polishing rollers 222 can swing freely to form an arc structure, so that the cylindrical part is lifted by the arc structure, so that the multiple polishing rollers 222 can contact the cylindrical part, and the contact area between the polishing assembly and the cylindrical part is maximized, thereby improving the polishing effect of the cylindrical part.

[0045] At the same time, after the cylindrical part is placed on the arc structure, the fixing frame 32 of the clamping assembly can be used to apply pressure to the cylindrical part on the grinding assembly, so that the surface of the cylindrical part can be more closely in contact with the grinding roller 222. In this way, when the first driving member 223 controls the grinding roller 222 to rotate, the friction between the grinding roller 222 and the cylindrical part is also greater, and the surface of the cylindrical part can be easily and effectively ground, which 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 The local enlarged picture of M is provided. Figure 4 As shown, the grinding assembly further includes: a first fixing 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 on 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 driving 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 driving member 223 passes through the first fixing plate 24 , and at least part of the output shaft of the first driving member 223 protrudes from the first fixing plate 24 .

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

[0050] Exemplarily, the first driving member 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] Exemplarily, the transmission belt 27 may be a belt, and the friction coefficient between the belt and the transmission wheel is relatively large, so that the power can be effectively transmitted from the second transmission wheel 26 to the first transmission wheel 25 .

[0052] In the above implementation, after the cylindrical parts are placed on the grinding rollers 222, the first driving member 223 is controlled to rotate, thereby driving the second transmission wheel 26, the first transmission wheel 25 and the rotating shaft to rotate in sequence, and the rotating shaft is coaxially connected to the grinding roller 222, so the rotating shaft can drive the grinding roller 222 to rotate together. In this way, the cylindrical parts can be polished more finely by rotating the grinding roller 222.

[0053] Alternatively, if Figure 1 As shown, the grinding assembly further includes two supporting structures, which are arranged on the base 10 at intervals, and the two supporting structures sandwich a plurality of grinding components, and the arrangement direction of the supporting structures is perpendicular to the arrangement direction of the support plates 21 .

[0054] like Figure 4As shown, the supporting structure includes: a cross plate 281, a first hydraulic cylinder 282, a second fixed plate 283, a second hydraulic cylinder 284 and a baffle 285, the first hydraulic cylinder 282 is located on the base 10, the piston rod of the first hydraulic cylinder 282 is connected to the plate surface of the cross plate 281, the second fixed plate 283 is located on the plate surface of the cross plate 281 close to the base 10, the cylinder barrel of the second hydraulic cylinder 284 is connected to the second fixed plate 283, 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, and the cross plate 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 be inserted and matched with the positioning hole 286, and the plate surface of the positioning plate 224 close to the base 10 is located on the plate surface of the cross arm plate 281 away from the base 10.

[0056] In the 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 contract, so that the piston rod of the second hydraulic cylinder 284 pulls the baffle 285 to move in the direction close to the grinding roller 222 until the positioning hole 286 of the baffle 285 is mounted on 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 crossbar 281 to prevent the grinding roller 222 from swinging.

[0057] When the grinding part and the support structure are locked, Figure 1 As shown, the positioning plates 224 of each grinding component are all overlapped on the cross arm plate 281, so that each grinding roller 222 is in the same horizontal plane. At this time, a flat plate part can be placed on the grinding component to perform grinding operation on the flat plate part.

[0058] When it is necessary to control the grinding component to unlock from the support structure, the second hydraulic cylinder 284 is driven to extend, so that the piston rod of the second hydraulic cylinder 284 pushes the baffle plate 285 away from the grinding roller 222 until the positioning hole 286 of the baffle plate 285 is separated from the positioning plate 224. Figure 1 As shown, the positioning plate 224 is overlapped on the cross arm plate 281 so that the grinding rollers 222 are in the same horizontal plane.

[0059] When the grinding component and the supporting structure are unlocked, the first hydraulic cylinder 282 needs to be controlled to retract, that is, the first hydraulic cylinder 282 is used to pull the cross arm plate 281 downward toward the base 10, so that the positioning plate 224 is no longer connected to the cross arm plate 281. In addition to the U-shaped plates 221 of the grinding components on both sides being connected to the two supporting plates 21 respectively, the middle grinding component will sag under the action of gravity, so that the multiple grinding rollers 222 will form an arc structure to carry the cylindrical parts, thereby grinding the cylindrical parts more efficiently.

[0060] Alternatively, if 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 cross arm plate 281 close to the base 10, the first guide rod 287 is inserted in the first guide cylinder 289, and the two ends of the first guide rod 287 are respectively connected to the baffle 285 and the retaining ring 288.

[0061] By providing a retaining ring 288 and a first guide rod 287 inserted in the retaining ring 288, the first guide rod 287 can only be telescopically moved within the range limited by the retaining ring 288, and the first guide rod 287 is also connected to the baffle 285, therefore, the moving route of the baffle 285 can also be limited to prevent the baffle 285 from being skewed when moving and unable to be mounted in the positioning plate 224.

[0062] Alternatively, if Figure 1 , 2 As shown, the grinding assembly also includes: a mounting seat 41 and a T-shaped slider 42. The mounting seat 41 corresponds to the support plate 21 one by one, the T-shaped slider 42 corresponds to the mounting seat 41 one by one, the support plate 21 is connected to the corresponding mounting seat 41, and the mounting seat 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 slide groove 11 , the T-shaped slide groove 11 extends along the arrangement direction of the support plate 21 , and the T-shaped slider 42 is slidably disposed in the T-shaped slide groove 11 .

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

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

[0066] Alternatively, if Figure 2 As shown, the grinding assembly also includes: two third fixed plates 29 and two third hydraulic cylinders 210. The two third fixed plates 29 are arranged on the base 10 at intervals, and the two support plates 21 are located between the two third fixed plates 29. The third hydraulic cylinder 210 is arranged between the opposite support plates 21 and the third fixed plates 29, and the two ends of the third hydraulic cylinder 210 are respectively connected to the corresponding support plates 21 and the third fixed plates 29.

[0067] By setting the third fixed plate 29 as the installation base of the third hydraulic cylinder 210, the third hydraulic cylinder 210 can be extended and retracted against the third fixed plate 29, thereby pushing and pulling the two support plates 21 closer to or away from each other, so as to adjust the diameter of the arc structure surrounded by the grinding rollers 222, so that the arc structure can fit more closely with the cylindrical part.

[0068] Alternatively, if Figure 2 As shown, the grinding assembly further includes ribs 211 , which correspond to the support plates 21 one by one, and the ribs 211 are connected to the corresponding support plates 21 and the corresponding mounting seats 41 .

[0069] In the disclosed embodiment, the support plate 21 and the mounting seat 41 are vertically connected, and a rib 211 is provided between the support plate 21 and the mounting seat 41 to enhance the connection reliability between the support plate 21 and the mounting seat 41 and improve the reliability of the grinding device.

[0070] Alternatively, if 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 pressing 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 second n-shaped plate 322 can be controlled to rise and fall relative to the first n-shaped plate 31 by utilizing the extension and retraction of the fourth hydraulic cylinder 321 .

[0073] Exemplarily, 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 moving route of the second n-shaped plate 322, thereby preventing the second n-shaped plate 322 from tilting when moving.

[0074] like Figure 1 , 2As shown, the second n-shaped plate 322 is located on the side of the first n-shaped plate 31 close to the base 10, the end face where the straight edge of the second n-shaped plate 322 is located 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 close to the base 10, the pressure roller 326 is located on the side of the fourth fixed plate 325 close to the base 10, and the pressure roller 326 is rollingly arranged on the fourth fixed plate 325.

[0075] Exemplarily, 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 can limit the moving route of the fourth fixing plate 325, thereby preventing the fourth fixing plate 325 from tilting when moving.

[0076] In the above implementation, the third n-shaped plate 323 and the second n-shaped plate 322 are connected together, that is, 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. Among them, the fifth hydraulic cylinder 324 is also connected to the fourth fixed plate 325, so that the fifth hydraulic cylinder 324 can drive the pressure roller 326 on the fourth fixed plate 325 to rise and fall relative to the base 10. Therefore, the pressure roller 326 can be controlled to descend to the cylindrical part by lifting the fixed frame 32 to squeeze the cylindrical part, and the pressure roller 326 can be controlled to rise by lifting the fixed frame 32 to make the pressure roller 326 release the cylindrical part.

[0077] Alternatively, if Figure 1 As shown, the fixing frame 32 further includes two expansion structures, which are respectively located on two opposite plate surfaces of the third n-shaped plate 323, and the expansion structures are used to fix the cylindrical part to be polished.

[0078] Among them, the expansion 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, which can drive the second n-shaped plate 322 and the third n-shaped plate 323 to rise and fall, thereby driving the expansion structure to rise and fall together, thereby adjusting the height of the expansion structure, so that the expansion structure can be inserted from both ends of the cylindrical part to expand the cylindrical part and prevent the cylindrical part from slipping during the grinding process.

[0079] Figure 5 yes Figure 1 A local magnified image of N locations is provided. Figure 5 As shown, the expansion structure includes: a sixth hydraulic cylinder 327, a mounting plate 328, a second driving member 329, a first gear 330, a rotating column 331, a second gear 332, a cylinder 333 and an expansion member.

[0080] like Figure 5As shown, the cylinder barrel of the sixth hydraulic cylinder 327 is connected to the plate 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, 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 are meshed.

[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, and the tightening piece is located at the other end of the cylinder 333, and the tightening piece is used to be inserted into the inner hole of the cylindrical part to be polished.

[0082] In the above implementation, the second driving member 329 of the expansion structure can drive the first gear 330 and the second gear 332 to rotate, and the second gear 332 can drive the cylinder 333 to rotate, and the cylinder 333 is also equipped with an expansion member. In this way, after the expansion member expands the cylindrical part, the expansion member is driven to rotate by the second driving member 329, so that the purpose of controlling the cylindrical part to rotate at the same time during the grinding process can be achieved, which can effectively improve the grinding efficiency of the cylindrical part.

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

[0084] Alternatively, if Figure 5 As shown, the expansion member includes: a support rod 334, an anti-skid pad 335, a seventh hydraulic cylinder 336, a sliding block 337, a fixing block 338 and a push-pull rod 339.

[0085] like Figure 5 As shown, the end surface of the cylinder 333 away from the mounting plate 328 is provided with a plurality of long grooves 3330 , and the plurality of long grooves 3330 are arranged at intervals in the circumferential direction.

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

[0087] like Figure 5 As shown, the seventh hydraulic cylinder 336 is disposed in the cylinder body 333 , the cylinder barrel of the seventh hydraulic cylinder 336 is fixed on the end surface of the second gear 332 , and 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 through a pin shaft, and the other end of the support rod 334 is installed with an anti-slip pad 335. One end of the push-pull rod 339 is hinged to the fixed block 338 through a pin shaft, and the other end of the push-pull rod 339 is hinged to the middle part of the support rod 334 through a pin shaft.

[0089] In the above implementation, the seventh hydraulic cylinder 336 is used to push the slider 337 to slide in the cylinder 333, so that the slider 337 drives the fixed block 338 to slide along the long groove 3330, and the fixed block 338 drives the push-pull rod 339 to slide, and the other end of the push-pull rod 339 is hinged at the middle of the support rod 334. In this way, when the push-pull rod 339 is pushed out, it will push the support rod 334 to expand, so that the anti-skid pad 335 at the other end of the support rod 334 will support the inner hole of the cylindrical part, thereby expanding the cylindrical part. When the push-pull rod 339 is pulled back, the push-pull rod 339 pulls the support rod 334 back, so that the anti-skid pad 335 at the other end of the support rod 334 is retracted toward the central axis of the cylinder 333, so that the anti-skid pad 335 no longer expands the cylindrical part.

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

[0091] When grinding a flat part such as a flat plate, first, directly start the first driving member 223. At this time, the grinding rollers 222 are all driven by the first driving member 223 to rotate at high speed. At this time, the flat part is placed with its grinding surface facing downward directly on multiple grinding rollers 222 distributed on the same horizontal plane, and the part is moved back and forth. In this way, it can be ground. In this process, the pressure roller 326 can be lowered by the fourth hydraulic cylinder 321 or the fifth hydraulic cylinder 324, and the part is squeezed by the pressure roller 326, so that the grinding roller 222 can better grind the surface of the part. In this process, the support structure supports the multiple grinding rollers 222, so that the multiple grinding rollers 222 are always distributed in the same horizontal plane, and the grinding rollers 222 are prevented from moving down under the gravity of the part.

[0092] When grinding the cylindrical part, first separate the two supporting structures from the positioning plates 224 at both ends of the grinding part. The specific process is as follows: first drive the second hydraulic cylinder 284 to extend, so that the piston rod of the second hydraulic cylinder 284 pushes the baffle 285 away from the grinding roller 222 until the positioning hole 286 of the baffle 285 is separated from the positioning plate 224. At this time, the positioning plate 224 overlaps the cross arm plate 281, so that the grinding rollers 222 are in the same horizontal plane.

[0093] Then, the first hydraulic cylinder 282 is controlled to contract, that is, the first hydraulic cylinder 282 is used to pull the cross arm plate 281 downward toward the base 10, so that the positioning plate 224 is no longer overlapped on the cross arm plate 281. In addition to the U-shaped plates 221 of the grinding assemblies on both sides being connected to the two support plates 21 respectively, the middle grinding assembly will sag under the action of gravity, so that the multiple grinding rollers 222 will form an arc structure to carry the cylindrical parts, thereby grinding the cylindrical parts more efficiently.

[0094] Then, the cylinder 333 is adjusted up and down by the fourth hydraulic cylinder 321 so that the axis of the cylinder 333 is aligned with the axis of the cylindrical part. Then, the sixth hydraulic cylinder 327 is controlled to extend the cylinder 333 into the inner hole of the cylindrical part. At this time, the telescopic end of the seventh hydraulic cylinder 336 is controlled to extend, and the support rod 334 is pushed through the push-pull rod 339. In this way, several support rods 334 are synchronously opened toward the inner wall of the cylindrical part. When the anti-skid pad 335 at the end of the support rod 334 is close to the inner wall of the cylindrical part, the seventh hydraulic cylinder 336 is stopped, and the second driving member 329 is started. When the second driving member 329 is running, it drives the second gear 330 through the first gear 330. 32 rotates, and when the second gear 332 rotates, the cylindrical part is synchronously driven to rotate through the support rod 334 opened on the cylinder 333, and the first driving member 223 is started. At this time, several grinding rollers 222 are driven by the first driving member 223 to rotate at a high speed. At this time, several grinding rollers 222 are drooping and contacting the outer wall of the cylindrical part, and then several grinding rollers 222 can grind the cylindrical part at the same time, so that the grinding efficiency is improved. In this process, the pressure roller 326 can be lowered by the fifth hydraulic cylinder 324, and the cylindrical part can be squeezed by the pressure roller 326, so that the grinding roller 222 can better grind the surface of the part.
