With the technical solution of the present embodiment, the flipping unit includes a rotating structure 81 and a flipping structure 82 connected to the rotating structure 81, and the rotating structure 81 is rotatably disposed on the first housing 60. The first clamp 90 is disposed on the flip structure 82. When the workpiece to be processed needs to be turned over, the worker firstly installs the workpiece to be processed on the first clamp 90 and then adjusts the size of the first clamping space, so that the first clamp 90 clamps the workpiece to be processed.

Specifically, the rotating structure 81 is fixedly connected to the flipping structure 82 and rotates synchronously with the rotating structure 81, and the first gear structure 110 and the second gear structure 120 are spaced apart from each other in the vertical direction. After the first fixture 90 clamps the workpiece to be machined, the first driving device 70 is started, the first driving device 70 drives the first gear structure 110 to rotate, so that the first gear structure 110 (driving wheel) drives the second gear structure 120 (driven wheel) and the rotating structure 81 to rotate around the rotating axis of the rotating structure 81, and the rotating structure 81 drives the overturning structure 82, the first fixture 90 and the workpiece to be machined to synchronously rotate, so that the workpiece to be machined can be overturned.

Meanwhile, the support stability of the support assembly for the rotating structure 81 is improved by the arrangement, and the phenomenon that the rotating structure 81 shakes to influence the overturning accuracy of the overturning structure 82 is avoided.

Specifically, the supporting member 62 is a vertical plate, the second gear structure 120 is disposed between the two vertical plates, and the connecting member 821 is also located between the two vertical plates, so that on one hand, the internal structural layout of the turnover device is more reasonable and compact; on the other hand, the normal use of the turnover device is prevented from being influenced by the movement interference of the rotating shaft and other structures in the rotating process.

As shown in fig. 6 to 11, the first fixture 90 includes a mounting base 10, three clamping assemblies 20, a turntable 30 and a second driving device 40. Wherein, the mount pad 10 is disposed on the second support body 822, and the mount pad 10 has a mount cavity 11 and three mount grooves 12 communicated with the mount cavity 11. The three clamping components 20 are arranged in one-to-one correspondence with the three mounting grooves 12, and at least part of each clamping component 20 is slidably arranged in the mounting groove 12 corresponding to the clamping component. The three clamping assemblies 20 form a first clamping space around. The rotary table 30 is located in the mounting cavity 11, the rotary table 30 has three arc-shaped recesses 31, the three clamping assemblies 20 are arranged in one-to-one correspondence with the three arc-shaped recesses 31, and at least part of each clamping assembly 20 is slidably arranged in the arc-shaped recess 31 corresponding to the clamping assembly. The second driving device 40 is drivingly connected to the turntable 30 to drive the turntable 30 to rotate, so that each clamping assembly 20 is driven by the turntable 30 to slide along the corresponding mounting groove 12, thereby adjusting the size of the first clamping space.

Specifically, when the first clamp 90 is required to clamp the workpiece to be processed, the workpiece to be processed is firstly installed on the clamping assembly 20. After that, the second driving device 40 is started, the second driving device 40 drives the rotary table 30 to rotate, so that the rotary table 30 drives each clamping assembly 20 to slide along the corresponding mounting groove 12 and the corresponding arc-shaped concave portion 31, and the three clamping assemblies 20 synchronously slide towards directions away from each other to increase the size of the clamping space, thereby clamping the workpiece. Thus, after the second driving device 40 is started, the second driving device 40 can drive each clamping assembly 20 to slide along the corresponding mounting groove 12 through the turntable 30, so as to realize the automatic clamping or releasing of the first clamp 90 on the workpiece to be processed, thereby improving the automation degree of the first clamp 90 and reducing the labor intensity of workers.

It should be noted that the clamping manner of the first clamp 90 to the workpiece is not limited to this. In other embodiments, not shown in the drawings, the three clamping assemblies slide towards each other synchronously to reduce the size of the clamping space, thereby realizing the clamping of the workpiece to be processed. Like this, after starting second drive arrangement, second drive arrangement can drive each centre gripping subassembly through the carousel and slide along rather than corresponding mounting groove to realize that first anchor clamps treat the self-holding of machined part or release, promoted the degree of automation of first anchor clamps, reduced staff's intensity of labour

The number of the arc-shaped recesses 31 is not limited to this, and may be the same as the number of the clamp assemblies 20. Optionally, the mounting slots 12 are two, or four, or five, or six.

As shown in fig. 6 to 9, the mount 10 includes a cover plate 13 and a base plate 14. The cover plate 13 includes an annular plate body 131 and a first flange 132 connected to the annular plate body 131, and the annular plate body 131 has three mounting grooves 12, each mounting groove 12 extending in a radial direction of the annular plate body 131. The bottom plate 14 is connected with the first flange 132, and the bottom plate 14 and the cover plate 13 surround to form the mounting cavity 11. Wherein the annular plate 131 is arranged coaxially with the turntable 30. Thus, in the process that the turntable 30 rotates around the central axis thereof, each arc-shaped concave portion 31 drives the corresponding clamping component 20 to slide along the arc-shaped concave portion 31 and the mounting groove 12, so that each clamping component 20 slides towards the direction close to or away from the central axis, and the motion reliability of each clamping component 20 is further improved, and the situation that the first clamp 90 normally clamps the workpiece due to the fact that each clamping component 20 is jammed or stuck in the mounting groove 12 or the arc-shaped concave portion 31 is prevented.

Specifically, the cover plate 13 is detachably connected with the bottom plate 14, so that the rotary disc 30 is easier and simpler to disassemble and assemble or replace, and the operation difficulty of workers is reduced. Meanwhile, the cover plate 13 is arranged to provide sufficient space for the mounting cavity 11, so as to prevent the turntable 30 from moving and interfering with the mounting seat 10 during rotation to affect the normal use of the first clamp 90.

Thus, the above arrangement of the second flange 33 ensures a gap between the disc 32 and the base plate 14, thereby preventing the disc 32 from contacting the base plate 14 to affect the rotation of the turntable 30, and preventing the base plate 14 from rubbing against the disc 32 to cause structural wear.

Specifically, the arc-shaped concave portion 31 is an arc-shaped hole, and the central axis of the arc-shaped hole and the central axis of the disk 32 are arranged in parallel to each other. Thus, the arc-shaped concave part 31 is easier and simpler to process, and the processing difficulty and the processing cost are reduced.

Optionally, the first clamp 90 further includes a first friction reducing member disposed between the second flange 33 and the base plate 14. Thus, in the rotating process of the rotating disc 30, even if the second flanging 33 is in contact with the bottom plate 14, the friction force between the second flanging 33 and the bottom plate 14 can be reduced by the arrangement of the first anti-friction member, so that the structural wear of the rotating disc 30 and the bottom plate 14 is reduced, and the service life of the first clamp 90 is prolonged.

Optionally, a first friction reducing member is disposed between the first flange 132 and the rotating disc 30. Specifically, the first wear reducing member is disposed between the surface of the first flange 132 facing the rotary plate 30 and the rotary plate 30, and even if the first flange 132 contacts the rotary plate 30, the friction between the first flange 132 and the rotary plate 30 can be reduced by the above arrangement of the first wear reducing member, so that the structural wear of the cover plate 13 and the rotary plate 30 is reduced, and the service life of the first clamp 90 is prolonged.

Optionally, a first friction reducing member is provided between the annular plate body 131 and the disc body 32. Specifically, the first wear reducing member is disposed between the annular plate body 131 and the disc body 32, so that even if the annular plate body 131 contacts the disc body 32, the friction force between the annular plate body 131 and the disc body 32 can be reduced by the arrangement of the first wear reducing member, thereby reducing structural wear of the cover plate 13 and the turntable 30, and prolonging the service life of the first clamp 90.

Optionally, the first friction reducing member is made of a silicone or rubber material.

The second sliding structure 23 is connected with the clamping piece 21 through the first sliding structure 22, and the second sliding structure 23 is slidably arranged in the arc-shaped concave part 31. In this way, the mounting groove 12 is a straight groove, the first sliding structure 22 slides in the mounting groove 12, and the second sliding structure 23 slides in the arc-shaped concave portion 31, so as to avoid the jamming phenomenon during the sliding process, the first sliding structure 22 and the second sliding structure 23 can be processed into different shapes and sizes.

Specifically, the clamping member 21 is used for mounting the workpiece to be machined, the first sliding structure 22 can slide along the mounting groove 12, and the second sliding structure 23 can slide along the arc-shaped concave portion 31. In the rotating process of the turntable 30, the arc-shaped concave portion 31 contacts with the second sliding structure 23 and drives the second sliding structure to slide along the arc-shaped concave portion 31, and meanwhile, the second sliding structure 23 drives the first sliding structure 22 to move, so that the first sliding structure 22 slides along the mounting groove 12, and thus, each clamping assembly 20 slides along the mounting groove 12 corresponding to the clamping assembly.

In the present embodiment, the first sliding structure 22 and the second sliding structure 23 are integrally formed. The processing method of each clamp assembly 20 is not limited to this. Optionally, the first sliding structure 22 and the second sliding structure 23 are snapped, or glued, or connected by fasteners, or welded.

In this embodiment, the clamping member 21 is connected to the first sliding structure 22 through a fastener, so that the clamping member 21 and the first sliding structure 22 can be assembled and disassembled more easily and conveniently, and the difficulty in assembling and disassembling is reduced.
