A passive chain 1212 is provided at the periphery of the bottom of the base plate 121, and the transmission member 1222 is engaged with the passive When the chain 1212 causes the rotation motor 1221 to drive the transmission member 1222 to rotate, the passive chain 1212 drives the base plate 121 to rotate around the rotation axis. However, the actual structure of the driving mechanism is not limited to this.

In addition, in order to position the turntable 12 to prevent it from rotating during processing, the present invention may further include at least one positioning assembly 30, which is mounted on the base 11 so as to be liftable and movable, and the turntable 12 is provided with at least A positioning hole 1213. The at least one positioning component 30 is selectively raised to be inserted into the at least one positioning hole 1213 to prevent the turntable 12 from rotating. Preferably, the at least one positioning component 30 is connected to the rotation drive group 20, when After the at least one positioning component 30 is raised and inserted into the at least one positioning hole 1213, the rotation driving group 20 is driven to the driving position; when the rotation driving group 20 is lowered to the initial position, the at least one positioning component 30 is driven Lower to escape the at least one positioning hole 1213.

Regarding the actual structure of the first connection structure and the second connection structure, the first connection structure of each of the grinding barrels 13 may include at least one insertion groove 1321, and the second connection structure of the rotation drive group 20 may include at least one protrusion The at least one embedding groove 1321 and the at least one embedding block 21 are respectively a predetermined distance from the rotation axis (in this embodiment, it includes a plurality of the embedding grooves 1321 and a plurality of the embedding blocks 21, the The embedding grooves 1231 are arranged at intervals around the rotation axis, and the embedding blocks 21 are also arranged at intervals around the rotation axis), when the rotation driving group 20 is located at the driving position, the at least one embedding block 21 is embedded in the at least one embedding groove 1321 , So that the rotation driving group 20 and the grinding barrel 13 are connected in a non-rotatable manner, and can drive the grinding barrel 13 to rotate around the rotation axis; more specifically, each of the grinding barrels 13 includes a barrel body 131 and a body 132. The sheet body 132 is fixed on the bottom of the barrel 131. However, other connection structures can also be used. More extreme, for example, the first connection structure and the second connection structure can be made of materials with extremely high friction, and the huge surface friction drives the grinding bucket to rotate.

Regarding the first limiting structure and the second limiting structure, in this embodiment, the sheet body 132 has two opposite and parallel sides 1322, and the two side edges 1322 form the second limiting structure. Each of the first limiting structures includes two spaced apart and parallel protruding strips 1214, a positioning space is enclosed between the two protruding strips 1214, and the distance between the two protruding strips 1214 and the two side edges 1322 of the sheet 132 Correspondingly spaced, so that the sheet body 132 can be embedded in the positioning space with the two side edges 1322 corresponding to the two protruding bars 1214; preferably, each of the second limiting structures further includes a front stop protruding bar 1215, the The front bumper bar 1215 is located between the two convex bars 1214 and is perpendicular to the two convex bars 1214.

The front edge 1323 is for abutting against the front rib 1322. 1215. By this, when the grinding bucket 13 is arranged in the positioning space and its front end abuts against the front stop protrusion 1215, it means that the position and direction of the grinding bucket 13 are correct, so as to facilitate the ascent and combination of the rotation drive group 20 .

In view of the above, because the first connecting structure and the second connecting structure may not be completely interlocked before the rotation driving group 20 moves to the driving position, even if the interlocking is completed, the first limiting structure may not have been interlocked with the The second limiting structure is staggered, so that the rotation driving group 20 cannot drive the grinding barrel 13 to rotate. Therefore, whether the position of the rotation driving group 20 rises to a high enough position will be an important part of whether the automation operation can proceed smoothly. In this regard, the present invention uses the second detector 42 to detect the height detecting portion 44 of the rotation drive group 20, and only when the second detector 42 detects the height detecting portion 44, it represents The rotation drive group 20 has been raised to a sufficient height and can start to drive the grinding barrel 13 to rotate; on the other hand, if the turntable 12 is to be rotated to replace a different grinding barrel 13, it must be ensured that the rotation drive group 20 has been separated from the grinding Therefore, the present invention uses the first detector 41 to detect the height detecting portion 44 to confirm that the grinding barrel 13 has been separated from the rotation drive group 20, and the turntable 12 is rotated; and, in order to enable the inserts 21 to be able to To be correctly embedded in the grooves 1321, the grinding bucket 13 must also be rotated to a specific angle. Therefore, before descending to the initial position, the rotation driving group 20 uses its angle detecting portion 45 for the third detector 43 for detection (for example, the angle detecting portion 45 can be a notch 451 on one side of a detecting piece, and when the notch 451 corresponds to the third detector 43, the third detector 43 detects the angle detection portion 45), and rotates the rotation drive group 20 until the angle detection portion 45 is aligned with the third detector 43 (preferably, when the rotation drive group 20 is at the driving position and the When the third detector 43 does not detect the angle detecting portion 45, the rotation driving group 20 cannot be lowered to the initial position to ensure smooth operation), so that the angle of the grinding bucket 13 can be ensured to be correct. When the group 20 is lowered, the inserts 21 can be correctly inserted into the insert grooves 1321, that is, the first limiting structure and the second limiting structure are also fitted corresponding to each other, so that the grinding bucket 13 can It is positioned on the turntable 12.

Specifically, the rotation drive assembly 20 may include a body 22, a lifting shaft 23, and a rotation mechanism 24. The body 22 is disposed on the base 11, and the lifting shaft 23 is vertically pierced through the body 22. The rotation mechanism 24 is arranged at the lower end of the lifting shaft 23 to drive the lifting shaft 23 to rotate around the rotation shaft; in this embodiment, the main body 22 encloses a piston chamber 221, and the lifting shaft 23 is sheathed with a piston 231, The piston 231 is slidably disposed in the piston chamber 221 to divide the piston chamber 221 into an upper piston chamber and a lower piston chamber. The upper piston chamber and the lower piston chamber are respectively connected to a gas source or a liquid source, and the pressure Or hydraulically drive the piston 231 to move up and down in the piston chamber 221 to drive the lifting shaft 23 to rise and fall, which is beneficial to the control and scheduling of the automated manufacturing process; as for the rotation mechanism 24, it may include a rotating motor 241 and a A rotating shaft 242, a transmission wheel 243, a transmission belt 244, and a driven wheel 245. The rotating shaft 242 is arranged on the rotating motor 241 and driven to rotate, and the transmission wheel 243 is arranged on the rotating shaft 242 and synchronized therewith. When rotating, the driven wheel 245 is sleeved on the outside of the lifting shaft 23 and rotates synchronously with it. The transmission belt 244 is sleeved on the outside of the transmission wheel 243 and the driven wheel 245, so that the driven wheel 245 is driven by the transmission wheel 243. Rotation, however, the structure is not limited to this.

In actual use, first of all, under normal circumstances when no work is performed, as shown in FIGS. 6 and 7, the rotation drive group 20 is located at a lower initial position, and the first positioning structure and the second positioning structure are separated from each other. Do not interfere with each other. At this time, the grinding barrel 13 is not driven and rotated by the rotation drive group 20, and due to the mutual interference of the first limiting structure and the second limiting structure, the grinding barrel 13 is limited to the turntable 12 at a specific angle At a specific position, at this time, the turntable 12 can rotate to replace the grinding bucket 13 or cleaning bucket required for the grinding operation, without being disturbed by the rotation drive group 20, wherein the height of the height detecting portion 44 corresponds exactly to the first detecting With the detector 41, the system can learn the position and state of the rotation driving group to confirm whether the turntable can be rotated.

When the grinding operation is to be performed, as shown in Figs. 8 and 9, the rotation driving group 20 can be driven to the driving position. In this process, the first positioning structure and the second positioning structure are combined with each other to make the grinding barrel 13 is lifted by the rotation drive group 20, so that the first limiting structure and the second limiting structure are staggered without interfering with each other. At this time, the rotation of the rotation drive group 20 can drive the grinding bucket 13 to rotate together to facilitate the grinding process The height of the height detector 44 corresponds exactly to the second detector 42, so that the system can know the position and state of the rotation drive group 20 to confirm whether the rotation drive group 20 can be driven to rotate.

In particular, since the first limiting structure and the second limiting structure are fitted with each other in a specific direction and angle, before lowering the grinding bucket 13, it is necessary to confirm that the grinding bucket 13 and the turntable 12 are facing each other. Whether the angle is correct, for this, the angle detecting part 45 and the third detector 43 can be used to rotate the rotation drive group 20 until the angle detecting part 45 is aligned with the third detector 43 to detect it, that is, It means that the direction and angle of the grinding bucket 13 are correct, so that the first limiting structure and the second limiting structure can be combined correctly.

Among them, the first limiting structure of the present invention adopts protruding strips 1214, and the second limiting structure adopts a rectangular profile sheet 132. In addition to being easy to manufacture and assemble, it can also ensure that the grinding bucket can enter the positioning space horizontally, reducing the need for users to change The burden of barrel time.

Thereby, the barrel changing device and the lifting device of the automatic processing machine of the present invention can quickly replace the grinding barrel without manual transportation, and only one set of the autorotating drive group with the lifting clutch function is required, which greatly reduces the weight burden and machine tool of the turntable. The volume of the table, the detection group is used to ensure that the height and direction of the grinding barrel are correct, which is very conducive to the progress of the fully automated process, which is actually expected by the relevant processing industry. However, the above embodiments are only to illustrate and illustrate the technical content of the present invention. The patent scope of this patent shall be subject to the scope of patent application described later.
