DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field to which the present invention belongs. "Including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0028] In view of the problems existing in the prior art, an embodiment of the present invention provides a part clamping and rotating mechanical structure, such as Figure 1 As shown, the part clamping rotating mechanical structure includes a clamping jaw 1 for clamping a workpiece, a driving rotating mechanism 2, a monitoring mechanism 3 and a sleeve 4. The driving rotating mechanism 2 is arranged between the clamping jaw 1 and the sleeve 4 and is used for connecting the clamping jaw 1 and the sleeve 4. The driving rotating mechanism 2 is used to drive the clamping jaw 1 to rotate relative to the sleeve 4. By arranging the driving rotating mechanism 2 between the clamping jaw 1 and the sleeve 4, the clamping jaw 1 can rotate 360° relative to the sleeve 4. The monitoring mechanism 3 is arranged on the driving rotating mechanism 2, and the monitoring mechanism 3 is used to monitor the state of the workpiece.

[0029] In one embodiment, if Figure 1 and Figure 2As shown, the driving rotating mechanism 2 includes a supporting box 21, and a rotating seat 22 is rotatably provided on one side plate of the supporting box 21 (which can be understood as the left side plate), and the rotating seat 22 is located at one end (which can be connected as the left end) outside the supporting box 21 and is fixedly connected to a supporting platform 23, and the supporting platform 23 is connected to the clamping jaw 1, and a connecting block 24 is fixedly connected to the other side plate of the supporting box 21 (which can be understood as the right side plate), and the connecting block 24 is fixedly connected to the sleeve 4, and the rotating seat 22 is located at one end (which can be connected as the right end) inside the supporting box 21 and is fixedly connected to a first rotating rod 25, and the free end of the first rotating rod 25 is fixedly connected to the driving end of the first driving motor 26, and the first driving motor 26 is fixedly arranged on the inner wall of the supporting box 21.

[0030] In one embodiment, the monitoring mechanism 3 includes a support ring 31, the support ring 31 is sleeved outside the support box 21, and a fixing rod 33 is fixedly arranged on the inner ring wall of the support ring 31, and the free end (which can be understood as the lower end) of the fixing rod 33 is fixedly connected to the outer wall of the support box 21, and the support ring 31 is provided with N first monitors 32 on the side (which can be understood as the left side) facing the clamp 1, and the first monitors 32 are used to collect the posture of the workpiece clamped by the clamp 1, and the N first monitors 32 are arranged in a ring shape, and N is a positive integer greater than or equal to 3. It should be understood that in the actual implementation process, the number of the first monitors 32 can be set to 3, 4 or more, and the purpose of such a setting is to achieve all-round monitoring of the posture of the workpiece. The first monitor 32 can adopt AI technology and / or Internet of Things technology.

[0031] During operation, when the first monitor 32 collects a signal that the workpiece needs to be adjusted, it controls the first drive motor 26 to start. The first drive motor 26 will rotate the rotating seat 22 through the first rotating rod 25. The rotation of the rotating seat 22 will rotate the workpiece through the supporting platform 23 and the clamp 1 to achieve adjustment of the workpiece posture.

[0032] In one embodiment, if Figure 2 and Figure 3As shown, the part clamping rotating mechanical structure also includes a locking mechanism 5, which is used to lock the adjusted posture of the workpiece, and the structural design of the locking mechanism 5 is reasonable. In the process of adjusting the posture of the workpiece, the locking mechanism 5 is in an unlocked state for the workpiece. The locking mechanism 5 is used to lock the workpiece after the posture is adjusted. The locking mechanism 5 includes an electromagnet 51 fixedly arranged in the support box 21, and one end (which can be understood as the right end) of the first guide limit assembly 52 is fixedly arranged on the side wall of the electromagnet 51, and the other end (which can be understood as the left end) of the first guide limit assembly 52 is connected to a magnet block 53, and a locking rod 54 is fixedly arranged on the magnet block 53, and the locking rod 54 is movably inserted in the side plate of the support box 21, and the locking rod 54 is movably inserted in the locking groove 55, and the locking groove 55 is provided on the supporting platform 23, and the locking groove 55 is provided with M, and M is a positive integer greater than or equal to 2. In the specific implementation process, the number of the locking grooves 55 can be 2, 3 or more.

[0033] During operation, when the first monitor 32 starts the first drive motor 26, the electromagnet 51 is also synchronously controlled to be energized. After being energized, the electromagnet 51 will generate magnetism, and under the action of the magnetic force, the magnet block 53 will be attracted to move to the right. The rightward movement of the magnet block 53 will move the locking rod 54 to the outside of the locking groove 55. At this time, the unlocking process is realized, and the supporting platform 23 can rotate. After the posture adjustment of the workpiece is completed, the first monitor 32 controls the electromagnet 51 to be powered off. At this time, under the push of the first guide limit assembly 52, the locking rod 54 will make a reset movement to the left and enter the other locking groove 55, thereby locking the supporting platform 23, and then locking the current posture of the workpiece.

[0034] In one embodiment, if Figure 4 As shown, the M locking grooves 55 are arranged in an equidistant annular shape, and there is a gap between two adjacent locking grooves 55, the size of the gap is less than 0.5 mm, and an anti-stuck groove 56 is opened at one end of the locking rod 54 located in the locking groove 55, and the groove cavity of the anti-stuck groove 56 is a truncated cone structure. This arrangement allows the locking rod 54 to better enter the locking groove 55.

[0035] In one embodiment, the first guide limit assembly 52 includes a first guide limit rod 521, a first guide limit cylinder 522 and a first guide limit spring 523, the first guide limit rod 521 is movably inserted in the first guide limit cylinder 522, the first guide limit spring 523 is wound and arranged outside the first guide limit rod 521, and one end of the first guide limit spring 523 is fixedly connected to the side wall of the first guide limit rod 521, and the other end of the first guide limit spring 523 is fixedly connected to the outer wall of the first guide limit cylinder 522, the first guide limit rod 521 is connected to the magnet block 53, and the first guide limit cylinder 522 is connected to the electromagnet 51. The setting of the first guide limit assembly 52 can, on the one hand, play a guiding and supporting role for the magnet block 53, so that the magnet block 53 can only move left and right in the horizontal direction, and on the other hand, can play a role in buffering the impact force. At the moment when the magnetic attraction acts on the magnet block 53, the speed of the magnet block 53 will be very fast. If it hits the electromagnet 51, it will cause damage to the equipment. The setting of the first guide limit assembly 52 can buffer the movement of the magnet block 53, thereby protecting the equipment. At the same time, the setting of the first guide limit assembly 52 can also provide a reset force for the magnet block 53 when it is reset. Specifically, when the magnet block 53 moves to the right under the action of the magnetic attraction, the first guide limit assembly 52 will be compressed. When the magnet block 53 loses the magnetic attraction, the compressed first guide limit assembly 52 is reset. In this way, during the reset process of the first guide limit assembly 52, the magnet block 53 will also be reset.

[0036] In one embodiment, if Figure 5 As shown, there are two combined structures of the magnet block 53 and the locking rod 54, and the two combined structures are symmetrically arranged, the two locking rods 54 are both arranged on the supporting plate 6, and the magnet block 53 and the supporting plate 6 are arranged to conflict with each other, the supporting plate 6 is used to connect the magnet block 53 with the first guide limit assembly 52, and the first guide limit rod 521 is fixedly connected to the supporting plate 6. Such an arrangement can achieve a better locking effect.

[0037] In one embodiment, if Figure 6 , Figure 7 and Figure 8As shown, the part clamping and rotating mechanical structure also includes an adjustment mechanism 8, which is used to fine-tune the position of the locking rod 54. Specifically, when the left end of the locking rod 54 abuts against the supporting platform 23 and does not enter the locking groove 55, or does not completely enter the locking groove 55, the adjustment mechanism 8 will rotate the locking rod 54 so that the locking rod 54 can accurately enter the locking groove 55. The adjustment mechanism 8 includes an arc hole 81 provided on the supporting plate 6, a movable tube 82 is movably inserted in the arc hole 81, the locking rod 54 is movably inserted in the movable tube 82, an adjustment spring 85 is wound around the locking rod 54, one end of the adjustment spring 85 is fixedly connected to the side wall of the movable tube 82, and the other end of the adjustment spring 85 is fixedly connected to the side wall of the locking rod 54. A limit slider 83 is fixedly provided on the outer wall of the movable tube 82, and the limit slider 83 is movably provided in the limit slide groove 84. 84 is opened on the side wall of the arc-shaped hole 81, and the adjustment mechanism 8 also includes a second driving motor 86, and the second driving motor 86 is fixedly set on the fixed baffle 87, and the fixed baffle 87 is fixedly set on the supporting plate 6. The driving end of the second driving motor 86 is fixedly connected with a second rotating rod 88, and the lower end of the second rotating rod 88 is rotatably set on the supporting plate 6. The second rotating rod 88 is fixedly sleeved with a fixed plate 89, and a tilting rod 810 is fixedly set on the fixed plate 89, and the free end of the tilting rod 810 is fixedly connected to the magnet block 53.

[0038] During operation, when the left end of the locking rod 54 abuts against the supporting platform 23 and does not enter the locking groove 55, or does not completely enter the locking groove 55, the second drive motor 86 will be started. The start of the second drive motor 86 will cause the second rotating rod 88 to rotate. The rotation of the second rotating rod 88 will cause the magnet block 53 to rotate through the fixed plate 89 and the tilting rod 810. The rotation of the magnet block 53 will cause the locking rod 54 to rotate. The rotation of the locking rod 54 will enable the locking rod 54 to accurately enter the locking groove 55.

[0039] In one embodiment, a second monitor 7 is provided on the lower end surface of the support plate 6. The second monitor 7 can monitor in real time whether the locking rod 54 enters the locking groove 55. When it is monitored that the left end of the locking rod 54 abuts against the support platform 23 and does not enter the locking groove 55, or does not enter the locking groove 55 completely, the second drive motor 86 will be started to work; when it is monitored that the left end of the locking rod 54 enters the locking groove 55 completely, the second drive motor 86 will be controlled to be turned off. It is worth noting that the second monitor 7 uses artificial intelligence technology and / or Internet of Things technology.

[0040] In a special construction environment, network technology may fail. In order to compensate for this situation and enable the equipment to operate normally, in one implementation, Fig. 9 and Fig.10 As shown, the part clamping rotating mechanical structure also includes a control mechanism 9, which includes a first electrode contact piece 91 fixedly arranged outside the locking rod 54, and a second electrode contact piece 92 is matched above the first electrode contact piece 91. During operation, when the left end of the fixed rod 54 abuts against the supporting platform 23 and does not enter the locking groove 55, or does not completely enter the locking groove 55, it will abut the locking rod 54 to move upward relative to the movable tube 82, and the upward movement of the locking rod 54 will carry the first electrode contact piece 91 to move upward. When the first electrode contact piece 91 contacts the second electrode contact piece 92, the series circuit is contacted, and the second drive motor 86 starts to work, carrying the locking rod 54 to rotate. When the lower end of the locking rod 54 completely enters the locking groove 55, under the push of the adjustment spring 85, the locking rod 54 moves downward relative to the movable tube 82. At this time, the first electrode contact piece 91 is separated from the second electrode contact piece 92, the series circuit is disconnected, and the second drive motor 86 stops working.

[0041] In one example, Fig.10 As shown, a second guide and limit assembly 94 is fixedly provided on the upper end surface of the second electrode contact piece 92, and the upper end of the second guide and limit assembly 94 is fixedly provided on the fixed stop block 93, and the fixed stop block 93 is fixedly provided on the inner side wall of the movable tube 82, and the second guide and limit assembly 94 includes a second guide and limit rod 941, a second guide and limit cylinder 942, and a second guide and limit spring 943, the second guide and limit rod 941 is movably inserted in the second guide and limit cylinder 942, the second guide and limit spring 943 is wound around the outside of the second guide and limit rod 941, and the two ends of the second guide and limit spring 943 are respectively fixedly provided on the side wall of the second guide and limit rod 941 and the outer side wall of the second guide and limit cylinder 942, the second guide and limit rod 941 is connected to the second electrode contact piece 92, and the second guide and limit cylinder 942 is connected to the fixed stop block 93. The second guide and limit assembly 94 can not only play a guiding and supporting role for the movement of the second electrode contact piece 92 , but also provide a restoring force for the restoring process of the second electrode contact piece 92 .

[0042] Although the embodiments of the present invention are described in detail above, it is obvious to those skilled in the art that various modifications and variations can be made to these embodiments. However, it should be understood that such modifications and variations are within the scope and spirit of the present invention. Moreover, the present invention described herein may have other embodiments and may be implemented or realized in a variety of ways.
