In some embodiments, the fixture 30 further includes a second moving assembly 34 and a third moving assembly 35. The second moving assembly 34 is connected to the compensation assembly 33, and the second moving assembly 34 is used for driving the compensation assembly 33 to move along the second direction. The third moving assembly 35 is connected to the second moving assembly 34, and is configured to drive the second moving assembly 34 to move along the third direction.

In some embodiments, the second moving assembly 34 is connected to the compensation assembly 33 through the second moving plate 341, and the second moving plate 341 is connected to the output end of the second moving assembly 34. The second moving assembly 34 may be a ball screw or other linear module capable of linear reciprocating motion. The third moving assembly 35 is connected to the second moving assembly 34 through a third moving plate 351, and the third moving plate 351 is connected to an output end of the third moving assembly 35. The third moving assembly 35 may be a ball screw or other linear module capable of performing linear reciprocating motion. The second moving assembly 34 and the third moving assembly 35 are disposed to be stacked in the first direction.

It is understood that in other embodiments, the second moving assembly 34 and the third moving assembly 35 may be both linear cylinders. In the first direction, a third moving assembly 35 and a second moving assembly 34 can also be arranged above and below the first moving assembly, and the third moving assembly 35 is connected with the compensation assembly 33.

In some embodiments, the compensation assembly 33 includes a first compensator 331 and a second compensator 332. The first compensation member 331 is connected to the rotating mechanism 31, and the first compensation member 331 is configured to drive the rotating mechanism 31 to move along a first direction. The second compensation element 332 is connected to the first compensation element 331, and the second compensation element 332 is used for driving the first compensation element 331 to move along the second direction. In this manner, the rotation mechanism 31 can perform movement compensation in the first direction and the second direction by the compensation assembly 33.

In some embodiments, the first compensator 331 and the second compensator 332 may be ball screws or other linear modules capable of performing linear reciprocating motion. The first compensator 331 and the second compensator 332 are stacked up and down in the first direction, and the rotating mechanism 31 and the first compensator 331 are disposed left and right in the third direction. In this way, a compensating movement of the rotation mechanism 31 is achieved.

It is understood that in other embodiments, the first compensation member 331 and the second compensation member 332 may be both linear cylinders. The second compensator 332 and the first compensator 331 may be stacked up and down in the first direction, and the rotating mechanism 31 and the second compensator 332 may be disposed left and right in the third direction.

In some embodiments, rotation mechanism 31 includes a stationary assembly 311 and a rotating assembly 312.

The fixing member 311 is used to fix the workpiece 300. The fixing assembly 311 may fix the workpiece 300 by inwardly supporting the workpiece 300 or clamping the workpiece 300, may also fix the workpiece 300 by vacuum suction, and may also fix the workpiece 300 by pressing the workpiece 300 with an external cover plate. This embodiment is not limited to this. The rotating component 312 is disposed between the fixed component 311 and the compensation component 33 and is connected to the fixed component 311 and the compensation component 33, and the rotating component 312 is used for driving the fixed component 311 to rotate along the first direction. Specifically, the rotating member 312 is connected to the first compensating member 331. It can be understood that, when the grinding member 141 grinds the workpiece 300, the rotating assembly 312 does not drive the fixing assembly 311 and the workpiece 300 to rotate continuously, but after the grinding member 141 grinds one side of the workpiece 300, the rotating assembly 312 drives the fixing assembly 311 and the workpiece 300 to rotate 90 degrees, so that the grinding member 141 can grind the other side of the workpiece 300.

In some embodiments, the rotating assembly 312 may include a rotary drive 3121, an output end of the rotary drive 3121 being connected with the fixed assembly 311 through a second coupling 3122. The second coupling 3122 is used to make the rotary driving member 3121 drive the fixed components 311 in different directions to rotate. In this way, the rotating mechanism 31 is compact, which is advantageous for reducing the size of the deburring apparatus 100.

It will be appreciated that in other embodiments, the rotary drive member 3121 may also be directly connected to the stationary assembly 311.

In some embodiments, the sensing element may be disposed between the fixed component 311 and the rotating component 312 and connected to the fixed component 311 and the rotating component 312, respectively, and the sensing element is a two-dimensional force sensor capable of sensing forces in two directions. Alternatively, the sensing member is disposed between the rotating component 312 and the compensating component 33 and is connected to the fixing component 311 and the compensating component 33, respectively.

It is understood that, in other embodiments, the sensing elements may also be one-dimensional force sensors, and the number of the sensing elements is two, and the two sensing elements are respectively disposed on the first compensating element 331 and the second compensating element 332.

Referring to fig. 6, some embodiments provide a deburring apparatus 100 for polishing a 3D surface of a workpiece 300, where the 3D surface of the workpiece 300 may also be understood as a chamfer of the workpiece 300. The grinding member 141 of the grinding apparatus 10 rotates to a first angle α to grind the 3D surface of the workpiece 300. When the grinding member 141 grinds the workpiece 300, the acting force applied by the sensing member to the workpiece 300 is F, and the acting force F may be a combination of a horizontal acting force Fx and a vertical acting force Fz, where Fx is Fcos α and Fz is Fsin α, and it may also be understood that the horizontal acting force applied to the workpiece 300 is Fx and the vertical acting force is Fz. For example, when the horizontal force between the workpiece 300 and the grinding member 141 is Fx 'and the vertical force is Fz', the horizontal force indicates that the force between the workpiece 300 and the grinding member 141 belongs to the preset data. However, when Fx is greater or smaller than Fx 'and Fz is greater or smaller than Fz', both of them indicate that the force between the workpiece 300 and the grinding member 141 does not belong to the preset data, and the rotating mechanism 31 needs to compensate. For example, when Fx > Fx ', indicating that the horizontal force between the workpiece 300 and the grinding member 141 is larger, the compensation assembly 33 drives the rotation mechanism 31 away from the grinding member 141 in the horizontal direction, so that Fx ═ Fx'. When Fx < Fx ', indicating that the horizontal force between the workpiece 300 and the grinding member 141 is small, the compensation assembly 33 drives the rotation mechanism 31 to approach the grinding member 141 along the horizontal direction, so that Fx is Fx'. When Fz > Fz ', indicating that the vertical force between the workpiece 300 and the grinding member 141 is larger, the compensation assembly 33 drives the rotating mechanism 31 away from the grinding member 141 in the vertical direction, so that Fz is equal to Fz'. When Fz < Fz ', indicating that the vertical force between the workpiece 300 and the grinding member 141 is small, the compensation assembly 33 drives the rotating mechanism 31 to approach the grinding member 141 in the vertical direction, so that Fz is equal to Fz'. Therefore, the acting force between the grinding piece 141 and the workpiece 300 can be automatically compensated and adjusted, and the polishing amount of the grinding piece 141 to the workpiece 300 is uniform.

It is understood that in other embodiments, the workpiece 300 and the grinding member 141 only generate the force Fz in the vertical direction when the grinding member 141 grinds the upper plane of the workpiece 300. When the grinding member 141 grinds the side plane of the workpiece 300, the workpiece 300 and the grinding member 141 generate a force Fx only in the horizontal direction.

Some embodiments provide a deburring apparatus 100 that performs substantially the following steps: the polishing of a workpiece 300 is described as an example. First, the rotating component 312 rotates the fixing component 311, so that the fixing component 311 is located at an initial position for placing the workpiece 300 and facilitating subsequent positioning. Then, the workpiece 300 is placed on the fixing member 311. Then, the carrier 13 is driven to rotate by the carrier driving member 15, so that one of the grinding members 141 is positioned at a predetermined angle to grind the workpiece 300. Next, the grinding member 141 grinds the workpiece 300 by cooperation of the first moving assembly 12, the second moving assembly 34 and the third moving assembly 35 such that the grinding member 141 is opposed to the workpiece 300. Then, the workpiece 300 rotates the matching grinding member 141 to grind four edges of one surface of the workpiece 300 in cooperation with the rotating mechanism 31, the sensing member, and the compensating member 33, and after finishing grinding, the workpiece 300 is located at the initial position. Then, the two clamping members 232 of the turnover device 20 are positioned at two sides of the workpiece 300 through the cooperation of the first moving assembly 12, the second moving assembly 34 and the third moving assembly 35. The two clamping elements 232 are then driven closer together by the clamping drive 231, clamping the workpiece 300 in cooperation with the cams 233. Then, the first moving assembly 12 drives the frame 11 and the turnover device 20 to move upward. Then, the turnover driving member 22 drives the turnover frame 21 to rotate so as to drive the clamping assembly 23 and the workpiece 300 to turn over by 180 degrees. Then, the first moving assembly 12 drives the frame 11 and the turnover device 20 to move downward, so that the workpiece 300 is opposite to the fixing device 30. Then, the clamp driving unit 231 drives the two clamp members 232 away from each other to release the workpiece 300, and the workpiece 300 is fixed to the fixture 30. Then, the grinding member 141 continues to grind the other surface of the workpiece 300 by the cooperation of the first moving assembly 12, the second moving assembly 34 and the third moving assembly 35. Thus, the work of polishing and turning over the workpiece 300 is realized, and the polishing efficiency of the deburring device 100 is improved.

It can be understood that when the deburring device 100 polishes a plurality of workpieces 300 simultaneously, the polishing member 141, the clamping assembly 23 and the fixing device 30 corresponding to each workpiece 300 are operated synchronously, so as to ensure that the plurality of workpieces 300 are polished simultaneously.

According to the deburring device 100 provided by the embodiment of the application, the grinding member 141 of the grinding device 10 can grind the workpiece 300 through the cooperation of the first moving assembly 12, the second moving assembly 34 and the third moving assembly 35; by bearing the driving part 15 and the plurality of grinding parts 141, the deburring device 100 can meet the customized grinding requirement of the surface of the workpiece 300; the workpiece 300 is turned over by matching the turning device 20 and the fixing device 30, so that the workpiece 300 is automatically turned over, and the grinding efficiency of the deburring equipment 100 is improved; through the liquid spray pipe 17, the burr on the work piece 300 is easily got rid of to the piece 141 of polishing, avoids the piece 141 of polishing to glue with the burr together, is favorable to promoting the efficiency of polishing of burring equipment 100, guarantees the outward appearance quality of work piece 300.

The deburring apparatus 200 provided in the present embodiment is substantially similar in structure to the deburring apparatus 100 provided in the above-described embodiment. The difference lies in that: in this embodiment, the deburring device 200 can simultaneously polish the four workpieces 300, which is beneficial to improving the production efficiency of the workpieces 300. The third moving assembly 35 of the deburring device 200 is connected to the four compensating assemblies 33, and the third moving assembly 35 is used for simultaneously driving the four compensating assemblies 33 to move in the third direction. The second moving assembly 34 is connected to the third moving assembly 35 and is away from the compensating assembly 33. The second moving assembly 34 further includes two second buffers 342 disposed at two ends of the second moving assembly 34 along the third direction, and the third moving assembly 35 further includes two third buffers 352 disposed at two ends of the third moving assembly 35 along the second direction. Thus, the second buffer member 342 and the third buffer member 352 are advantageous for preventing the mechanism of the fixing device 30 from being bumped and damaged.

The deburring apparatus 200 further includes a base 40 and a plurality of supports 41 connected to the base 40. The supporting members 41 are used for supporting the base 40, the base 40 is used for carrying the fixing device 30 and the polishing device 10, and the supporting members 41 are uniformly arranged on one side of the base 40 departing from the fixing device 30 and the polishing device 10.

The number of the liquid ejecting tubes 17 is plural, and the plural liquid ejecting tubes 17 eject the liquid toward the workpiece 300 in the first direction and the second direction, respectively. Illustratively, taking the example of polishing one workpiece 300 as an example, four liquid-ejecting tubes 17 correspond to one workpiece 300, and when the polishing member 141 polishes the upper surface of the workpiece 300, two of the liquid-ejecting tubes 17 eject liquid toward the workpiece 300 in the second direction. When the grinding member 141 grinds the side of the workpiece 300, the other two liquid ejecting tubes 17 eject the liquid toward the workpiece 300 in the first direction. When the grinding member 141 grinds the 3D surface of the workpiece 300, the four liquid ejecting tubes 17 eject liquid toward the workpiece 300 in the first direction and the second direction at the same time.

Referring to fig. 9, the rotating mechanism 31 is connected to the first compensating member 331 of the compensating assembly 33 through the inductive bearing member 36.
