The power take-off 21 can be, for example, a pneumatic cylinder, and the power take-off 21 has a drive disk 211 at the top. The power connection turntable 22 is fixedly arranged on the driving turntable 211 and rotates synchronously with the driving turntable 211. The power output rotary table 23 is located above the power connection rotary table 22, in this embodiment, the power output rotary table 23 includes a lower table 231 and an upper table 232 connected by a pin P, but in other implementation aspects, the power output rotary table 23 may be a single table structure, and in detail, the lower table 231 and the power connection rotary table 22 of the power output rotary table 23 are rotatably disposed in the power setting portion 121 of the setting base 12 and are commonly penetrated by a rotating shaft S. The elastic connection 24 is for example a torsion spring, but the elastic connection 24 may also be another kind of elastic element. Elastic connector 24 has in this embodiment to follow upper and lower direction D1 extends and sets up partially through bolt P in a body 241 of power connection carousel 22, certainly the bottom of body 241 is towards keeping away from the direction of axis of rotation A extends and the joint set up in a first connecting portion 242 of power connection carousel 22, and certainly the top of body 241 is towards keeping away from the direction of axis of rotation A extends and the joint set up in a second connecting portion 243 of the lower disk 231 of power output carousel 23.

Referring to fig. 1, 2, 5 and 6, the upper disc body 232 of the power output rotary disc 23 has two power output portions 2321 extending upward, and the positioning module 3 is interlocked with the power output portions 2321 of the upper disc body 232 of the power output rotary disc 23 and used for positioning the workpiece 200. The positioning module 3 and the upper disc 232 are disposed on the positioning portion 122 of the base 1, and the positioning module 3 includes a driving turntable 31 and a driven turntable 32 capable of rotating around the rotation axis a, a plurality of elastic connection members 33 connected between the driving turntable 31 and the driven turntable 32, and two first sliding members 34 and two second sliding members 35 respectively linked with the driving turntable 31 and the driven turntable 32. In detail, the upper disc 232, the driving disc 31 and the driven disc 32 of the power output disc 23 are rotatably disposed in the positioning portion 122 of the installation base 12 and are commonly penetrated by a rotating shaft S.

In the present embodiment, the driving turntable 31 is located above the driven turntable 32. The driving rotary disk 31 has two driving connecting grooves 311 formed through and around the rotation axis a along the up-down direction D1, and the driven rotary disk 32 has two driven connecting grooves 321 formed through and around the rotation axis a along the up-down direction D1, wherein the extended length of the driven connecting grooves 321 is longer than the driving connecting grooves 311. The power output portion 2321 of the upper disc body 232 of the power output turntable 23 of the power module 2 is inserted into the driving connecting groove 311 through the driven connecting groove 321, and the power output portion 2321 can slide in the driving connecting groove 311 and in the driven connecting groove 321. However, the sliding range of the power output portion 2321 is limited by the driving connection groove 311 (the driven connection groove 321), so that when the power output portion 2321 slides to the end of the driving connection groove 311 (the driven connection groove 321), the driving turntable 31 (the driven turntable 32) is driven to rotate, and the driving turntable 31 (the driven turntable 32) is linked with the power output portion 2321.

The driving rotary disc 31 is flexibly linked with the driven rotary disc 32 through the elastic connecting piece 33, the elastic connecting piece 33 is, for example, a torsion spring, but the elastic connecting piece 33 can also be other kinds of elastic elements. The elastic connection member 33 has a body 331 extending along the up-down direction D1 and disposed on the driven turntable 32 through a pin P, a first connection portion 332 extending from the top end of the body 331 toward the direction away from the rotation axis a and disposed on the driving turntable 31, and a second connection portion 333 extending from the bottom end of the body 331 toward the direction away from the rotation axis a and disposed on the driven turntable 32.

The first sliding members 34 and the second sliding members 35 are disposed in the positioning portion 122 of the setting base 12 and can slide along a front-rear direction D2 (the second direction) and a left-right direction D3 (the third direction) in the positioning portion 122 of the setting base 12 along with the rotation of the driving turntable 31 and the driven turntable 32, the two first sliding members 34 are disposed at the front side and the rear side of the driving turntable 31 and the driven turntable 32, and the two second sliding members 35 are disposed at the left side and the right side of the driving turntable 31 and the driven turntable 32. It should be noted that, although the sliding direction of the first sliding member 34 and the sliding direction of the second sliding member 35 are the front-back direction D2 and the left-right direction D3 in the present embodiment, respectively, and thus the sliding direction of the first sliding member 34 and the sliding direction of the second sliding member 35 are perpendicular to each other, in other implementation manners, the sliding direction of the first sliding member 34 and the sliding direction of the second sliding member 35 may be other directions perpendicular to the up-down direction D1 (the first direction) and may not be perpendicular to each other, that is, the included angle between the sliding direction of the first sliding member 34 and the sliding direction of the second sliding member 35 is not limited to 90 degrees, and may be 30 degrees, 60 degrees or other angles. In addition, the number of the first sliders 34 and the number of the second sliders 35 may be only one, and is not limited to this embodiment.

The driving rotary plate 31 has two driving guide sliding grooves 312 penetratingly formed along the up-down direction D1 and respectively corresponding to the two first sliding members 34, the first sliding member 34 has a first slider 341 slidably disposed on the driving guide sliding grooves 312, the driven rotary plate 32 has two driven guide sliding grooves 322 penetratingly formed along the up-down direction D1 and respectively corresponding to the two second sliding members 35, and the second sliding member 35 has a second slider 351 slidably disposed on the driven guide sliding grooves 322. The driving guide runner 312 and the driven guide runner 322 extend along a first rotation direction R1 and gradually approach toward the rotation axis a. Therefore, by the cooperation of the driving guide sliding groove 312 and the first sliding block 341 and the driven guide sliding groove 322 and the second sliding block 351, when the driving turntable 31 and the driven turntable 32 rotate around the rotation axis a in the first rotation direction R1, the first sliding member 34 and the second sliding member 35 slide toward the rotation axis a; when the driving dial 31 and the driven dial 32 rotate around the rotation axis a in a second rotation direction R2 opposite to the first rotation direction R1, the first slider 34 and the second slider 35 slide away from the rotation axis a. In addition, in this embodiment, each of the two first sliding members 34 is provided with a first positioning arm 342 through a first connecting column 340, each of the two second sliding members 35 is provided with a second positioning arm 352 through a second connecting column 350, and the first positioning arm 342 and the second positioning arm 352 can contact the workpiece 200 placed on the support base 13 from the front side and the rear side and the left side and the right side together inwards (towards the direction of the rotation axis a) through the sliding of the first sliding member 34 and the second sliding member 35, and collectively position and clamp the workpiece 200, and further, in this way, the workpiece 200 can be divided into two parts. It should be noted that, although the first slide 34, the second slide 35, the first positioning arm 342 and the second positioning arm 352 are moved inward in the present embodiment to position the workpiece 200, in an alternative embodiment, for example, the driving turntable 31 and the driven turntable 32 are driven to rotate in the second rotation direction R2 to position the workpiece, and the first slider 34, the second slider 35, the first positioning arm 342 and the second positioning arm 352 can also move outwards (in a direction away from the rotation axis a) to position the workpiece 200 by using the same principle, for example, when the workpiece 200 is a frame structure, it is preferably stretched outward from the inside of the frame structure, the four components of the first sliding part 34, the second sliding part 35, the first positioning arm 342 and the second positioning arm 352 act on the inner side of the frame structure at the same time to complete the inner supporting positioning; of course, in other embodiments, the positioning of the frame structure may be accomplished by two or any three components disposed oppositely, and further, two components disposed oppositely may be clamped from outside to inside, and the other two components disposed oppositely may be supported from inside to outside to accomplish the positioning action together.

In this embodiment, the positioning module 3 further includes two first locking members 36 and two second locking members 37 for locking the first sliding member 34 and the second sliding member 35, respectively, two first locking elastic members 36A connected between the base 1 and the first locking members 36, two second locking elastic members 37A connected between the base 1 and the second locking members 37, two first positioning elastic members 34A connected between the base 1 and the first sliding member 34, and two second positioning elastic members 35A connected between the base 1 and the second sliding member 35. The first locking elastic member 36A, the second locking elastic member 37A, the first positioning elastic member 34A, and the second positioning elastic member 35A may be springs, for example, but in other embodiments, the above-described members may be other elastic members.

The first slider 34 further has a first locked inclined surface 343 at the bottom and facing outward, and the second slider 35 further has a second locked inclined surface 353 at the bottom and facing outward. The first locking member 36 has a first locking ramp 361 corresponding to the first locked ramp 343, and the second locking member 37 has a second locking ramp 371 corresponding to the second locked ramp 353. The first locking member 36 and the second locking member 37 are, for example, positioning portions 122 provided on the installation base 12 of the base 1 so as to be movable in the left-right direction D3 and the front-back direction D2, respectively. In detail, the first locking member 36 and the first locking elastic member 36A are a first guide rod L1 (see fig. 7) slidably sleeved in the base 1 and extending along the left-right direction D3, so that the first locking member 36 can slide along the left-right direction D3; the first locking member 37 and the first locking elastic member 37A are a second guide rod L2 (see fig. 7) slidably sleeved in the base 1 and extending along the front-back direction D2, so that the first locking member 37 can slide along the front-back direction D2.

The first locking elastic element 36A is configured to drive the first locking inclined surface 361 of the first locking element 36 to move along the left-right direction D3 and abut against the first locked inclined surface 343 of the first sliding element 34, so that the first sliding element 34 cannot slide in a direction away from the rotation axis a, and the first locking element 36 locks the position of the first sliding element 34; the second locking elastic member 37A is used to drive the second locking inclined surface 371 of the second locking piece 37 to move along the front-back direction D2 and abut against the second locked inclined surface 353 of the second slider 35, so that the first slider 34 cannot slide in a direction away from the rotation axis a, and the second locking piece 37 locks the position of the second slider 35. The first positioning elastic element 34A and the second positioning elastic element 35A are respectively used for driving the first sliding element 34 and the second sliding element 35 to move inwards (towards the rotation axis a) so as to position the workpiece 200. However, in the above-mentioned modified embodiment, the first positioning elastic element 34A and the second positioning elastic element 35A may also be respectively used to drive the first sliding element 34 and the second sliding element 35 to move outwards (towards the direction away from the rotation axis a) so as to position the workpiece 200.

In addition, the upper disc body 232 of the power output rotary disc 23 further includes a plurality of shift blocks 2322 rotatably disposed on the disc body of the power output rotary disc 23 through bolts P, a plurality of elastic members 2323 for shift blocks connected between the disc body of the power output rotary disc 23 and the shift blocks 2322, and a plurality of limit posts 2324 disposed on the disc body of the power output rotary disc 23 and against which the shift blocks 2322 abut. The elastic member 2323 for shifting block is, for example, a torsion spring, but in other embodiments, it may be another elastic element. When the power output rotary disc 23 rotates around the rotation axis a along the second rotation direction R2, the shifting block 2322 is used for abutting against the cylindrical structure 360 at the bottom of the first locking element 36 and the cylindrical structure 370 at the bottom of the second locking element 37, so as to drive the first locking inclined surface 361 of the first locking element 36 to be away from the first locked inclined surface 343 of the first sliding element 34, and drive the second locking inclined surface 371 of the second locking element 37 to be away from the second locked inclined surface 353 of the second sliding element 35, so that the first sliding element 34 and the second sliding element 35 are unlocked. However, in the above-mentioned modified embodiment, when the power output dial 23 rotates in the first rotation direction R1, the shift block 2322 may be pushed against the first locking element 36 and the second locking element 37, so as to unlock the lock. The shifting block elastic member 2323 is used for driving the shifting block 2322 to abut against the first locking member 36 and the second locking member 37, and the limiting column 2324 limits the position of the shifting block 2322 to prevent the shifting block 2322 from abutting against the first locking member 36 and the second locking member 37. Further, the elastic biasing force of the toggle block elastic member 2323 is larger than the elastic biasing forces of the first locking elastic member 36A and the second locking elastic member 37A.

The operation of the present embodiment will be described with reference to the drawings.

Referring to fig. 2, 4, 6, 7 and 8, in the initial state, the power output disc 23 is fixed at the initial position by the output force of the power output device 21, and the driving disc 31 and the driven disc 32 are also restricted at the initial position by the power output portion 2321 of the upper disc body 232 of the power output disc 23. At this time, the shifting block 2322 of the power output rotary disc 23 abuts against the first locking member 36 and the second locking member 37 to limit the first locking member 36 and the second locking member 37 at the initial positions, and at this time, the shifting block elastic member 2323, the first locking elastic member 36A and the second locking elastic member 37A are all in a compressed state. The first slider 34 and the second slider 35 are restricted by the driving dial 31 and the driven dial 32 to positions relatively distant from the rotation axis a, and the first positioning spring 34A and the second positioning spring 35A are in a compressed state. In this state, the first locked inclined surface 343 of the first slider 34 and the first locking inclined surface 361 of the first locking member 36 abut against each other, and the second locked inclined surface 353 of the second slider 35 and the second locking inclined surface 371 of the second locking member 37 abut against each other. In addition, at this time, the first positioning elastic piece 34A and the second positioning elastic piece 35A provide the urging force for the first slider 34 and the second slider 35 to slide toward the rotation axis a, and further provide the urging force for the driving turntable 31 and the driven turntable 32 to rotate in the first rotation direction R1, so that the power output portion 2321 abuts against the distal end of the driving connection groove 311 and the driven connection groove 321 in the second rotation direction R2.

Referring to fig. 2, 4, 6, 9 and 10, the power output rotary table 23 with the power output portion 2321 rotates around the rotation axis a along the first rotation direction R1. At this time, since the elastic force of the elastic member 2323 for shift block is greater than the elastic force of the first elastic member 36A and the second elastic member 37A for locking, the shift block 2322 of the power output rotary disc 23 still abuts against the first locking member 36 and the second locking member 37 to limit the first locking member 36 and the second locking member 37 at the initial positions, at this time, the first elastic member 36A and the second elastic member 37A for locking are both in a compressed state, and the elastic member 2323 for shift block is gradually released from the compressed state. The driving rotation disk 31 and the driven rotation disk 32 are allowed to rotate in the first rotation direction by the movement of the power output portion 2321, and at this time, the first slider 34 and the second slider 35 slide toward the rotation axis a by the urging force provided by the first positioning elastic member 34A and the second positioning elastic member 35A, and the driving rotation disk 31 and the driven rotation disk 32 rotate in the first rotation direction, but at this time, the power output portion 2321 is still abutted against the distal ends of the driving connection groove 311 and the driven connection groove 321 in the second rotation direction R2. In this state, the first locked inclined surface 343 of the first slider 34 and the first locking inclined surface 361 of the first locking member 36 are gradually disengaged and spaced apart from each other, and the second locked inclined surface 353 of the second slider 35 and the second locking inclined surface 371 of the second locking member 37 are gradually disengaged and spaced apart from each other.

Referring to fig. 2, 4, 6, 11 and 12, when the power output rotary disc 23 and the power output portion 2321 thereof continue to rotate around the rotation axis a along the first rotation direction R1, the shift block 2322 abuts against the limiting post 2324, in this state, the first locking elastic element 36A and the second locking elastic element 37A are gradually released, and the first locking element 36 and the second locking element 37 move synchronously with the shift block 2322 in close contact with the shift block 2322. However, since the first slider 34 and the second slider 35 still slide toward the rotation axis a, in this state, the first locked inclined surface 343 of the first slider 34 and the first locking inclined surface 361 of the first locking member 36 start to move simultaneously with keeping a distance therebetween, and the second locked inclined surface 353 of the second slider 35 and the second locking inclined surface 371 of the second locking member 37 start to move simultaneously with keeping a distance therebetween.

Referring to fig. 2, 4, 6, 13 and 14, when the power output turntable 23 and the power output portion 2321 thereof rotate to make the second positioning arm 352 disposed on the second slider 35 contact and position the workpiece 200, the second slider 35 stops sliding towards the rotation axis a, at this time, the driven turntable 32 interlocked with the second slider 35 stops rotating, the first slider 34 continues sliding towards the rotation axis a, and the driving turntable 31 interlocked with the first slider 34 also continues rotating along the first rotation direction R1, in which state, the elastic connection member 33 between the driving turntable 31 and the driven turntable 32 gradually starts to be compressed. At this time, since the driven turntable 32 is no longer rotated in the first rotation direction R1, the power output portion 2321 starts to slide in the driven connection groove 321 of the driven turntable 32 in the first rotation direction R1. In addition, in this state, the first locked inclined surface 343 of the first slider 34 and the first locking inclined surface 361 of the first locking member 36 are simultaneously moved with a distance therebetween, and the second locking inclined surface 371 of the second locking member 37 starts to move toward the second locked inclined surface 353 of the second slider 35, so that the distance between the second locked inclined surface 353 of the second slider 35 and the second locking inclined surface 371 of the second locking member 37 starts to gradually decrease.

Referring to fig. 2, 4, 6, 15 and 16, when the power output turntable 23 and the power output portion 2321 thereof rotate to make the first positioning arm 342 disposed on the first slider 34 contact and position the workpiece 200, the first slider 34 stops sliding toward the rotation axis a, and at this time, the driving turntable 31 interlocked with the first slider 34 also stops rotating. It should be noted that, since the driving rotary disk 31 is not rotated in the first rotation direction R1 from this moment, the power output portion 2321 starts to slide in the first rotation direction R1 in the driving connecting groove 311 of the driving rotary disk 31. In this state, the first locking inclined surface 361 of the first locking member 36 will start to move toward the first locked inclined surface 343 of the first sliding member 34, so that the distance between the first locked inclined surface 343 of the first sliding member 34 and the first locking inclined surface 361 of the first locking member 36 will start to gradually decrease.

It should be noted that, in the present embodiment, the contact area between the second positioning arm 352, which is linked with the driven turntable 32 and the second slider 35 and is firstly contacted with the workpiece 200, and the contact area between the first positioning arm 342, which is linked with the first slider 34 and is firstly contacted with the workpiece 200, and the workpiece 200 is larger, so that after the workpiece 200 is jointly clamped and positioned by the second positioning arm 352 in the left-right direction D3, there is still a possibility of slight movement in the front-back direction D2, so that the workpiece 200 can be subsequently jointly clamped and positioned by the first positioning arm 342 in the front-back direction D2. That is, by the driving turntable 31 and the driven turntable 32 connected by the elastic connection member 24 and the first positioning arm 342 of the first slider 34 and the second positioning arm 352 of the second slider 35 respectively sliding along with the rotation of the driving turntable 31 and the driven turntable 32, a problem that any one of the first positioning arm 342 of the first slider 34 and the second positioning arm 352 of the second slider 35 does not contact the workpiece 200 is avoided, and the workpiece 200 is stably positioned.

Referring to fig. 2, 4, 6, 17 and 18, when the power output rotary disc 23 rotates to make the first locking inclined surface 361 of the first locking member 36 abut against the first locked inclined surface 343 of the first sliding member 34 and the second locking inclined surface 371 of the second locking member 37 abut against the second locked inclined surface 353 of the second sliding member 35, the first sliding member 34 and the second sliding member 35 are in a locked state and cannot slide in a direction away from the rotation axis a. At this time, the shifting block 2322 abuts against the limiting column 2324 and is about to be separated from the contact with the first locking element 36 and the second locking element 37. At this time, since both the driven turntable 32 and the driving turntable 31 are no longer rotated in the first rotation direction R1, the power output portion 2321 slides in the driven connection groove 321 of the driven turntable 32 and the driving connection groove 311 of the driving turntable 31 in the first rotation direction R1.

Referring to fig. 2, 4, 6, 19 and 20, finally, when the power output portion 2321 slides to abut against the end of the driving connecting groove 311 in the first rotating direction R1 (in other implementation manners, it is also possible to first abut against the end of the driven connecting groove 321 in the first rotating direction R1), the output force of the power output device 21 is transmitted to the first positioning arm 342 on the first sliding member 34, so that the force path for the first positioning arm 342 to clamp the workpiece 200 is increased. In addition, at this time, the output acting force of the power output device 21 is also transmitted to the second positioning arm 352 on the second sliding member 35 through the driving rotary disk 31, the driven rotary disk 32 and the elastic connecting member 24 connected between the driving rotary disk 31 and the driven rotary disk 32, so that the force of the second positioning arm 352 clamping the workpiece 200 is slightly increased, and thus the positioning of the workpiece 200 is completed. In this case, if the power connection dial 22 and the power output dial 23 are rigidly linked by installing the fixed connection 25, the output acting force of the power output device 21 is directly transmitted to the first positioning arm 342 on the first slider 34 and the second positioning arm 352 on the second slider 35; when the power connection dial 22 and the power output dial 23 are in a flexible linkage state by detaching the fixed link 25, the output acting force of the power output device 21 is relatively gently transmitted to the first positioning arm 342 on the first slider 34 and the second positioning arm 352 on the second slider 35. In addition, the shifting block 2322 is completely separated from the first locking element 36 and the second locking element 37, so as to ensure that the first sliding element 34 and the second sliding element 35 are in a state of being locked by the first locking element 36 and the second locking element 37.

In addition, the process of the release of the positioning of the workpiece 200 is opposite to the above process, and is not described herein again.

In summary, the elastic connection member 24 connected between the power connection turntable 22 and the power output turntable 23 enables the power connection turntable 22 and the power output turntable 23 to be flexibly linked with each other, so as to avoid the damage or deformation of the workpiece 200 caused by the excessive output force of the power output device 21.

However, the above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and all the simple equivalent changes and modifications made according to the contents of the claims and the patent specification of the present invention are still within the scope covered by the present invention.
