DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not 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.

[0028] See also Figure 1-Figure 9The present invention provides a technical solution: a positioning and flipping device for machining mechanical parts, comprising a support frame 1, a disassembly ring 7 and a positioning ring 8, wherein a plurality of connecting plates 803 are fixedly connected to the positioning ring 8, and a movable positioning plate 9 is slidably connected to the connecting plate 803, and a toothed plate 901 is fixedly installed on one side of the movable positioning plate 9 close to the positioning ring 8, an external gear 802 is arranged on the connecting plate 803, and an internal gear 804 is arranged on the other side of the positioning ring 8 corresponding to the position of the external gear 802, the internal gear 804 is connected to the external gear 802 through a rotating shaft, and the external gear 802 is meshed with the toothed plate 901, a disassembly ring 7 is arranged on one side of the positioning ring 8, and dense teeth 703 are arranged around the outer ring of one side of the disassembly ring 7, and the dense teeth 703 are meshed with the internal gear 804, and support mechanisms are arranged on both sides of the disassembly ring 7 and the positioning ring 8, and the support mechanism supports the positioning ring 8 and the disassembly ring 7 without restricting their rotation, and can continuously drive the positioning ring 8 and the disassembly ring 7 to move.

[0029] Before using the present invention, the device is assembled. Figure 1 As shown, the upper end of the device is shown in the figure, and the upper end of the device is shown in the figure. Figure 1 The left end of the device is the approximate front view, and the device orientation is used for description, and no further description is given.

[0030] During operation, the positioning ring 8 and the disassembly ring 7 in the device are each provided with two groups and are arranged on the support frame 1. When processing the mechanical parts, the mechanical parts are clamped between the movable positioning plates 9, and the two ends of the long strip mechanical parts are fixed by the movable positioning plates 9. When fixing the mechanical parts, the disassembly ring 7 rotates to drive the dense teeth 703 to rotate, and the dense teeth 703 rotates to drive the internal gear 804 meshing therewith to rotate, and the internal gear 804 rotates to drive the external gear 802 to rotate, and the external gear 802 rotates to drive the tooth plate 901 to slide on the positioning ring 8, and the sliding of the tooth plate 901 drives the movable positioning plate 9 to slide toward the edge of the positioning ring 8. At this time, the mechanical parts are placed between the movable positioning plates 9, and at this time, the disassembly ring 7 rotates in the opposite direction, driving the dense teeth 703 to rotate in the opposite direction, and the dense teeth 703 rotates in the opposite direction. The inner gear 804 is driven to rotate in the opposite direction, and the reverse rotation of the inner gear 804 drives the outer gear 802 to rotate in the opposite direction, so that the movable positioning plate 9 is close to the center position of the positioning ring 8, and then the movable positioning plate 9 is close to the mechanical parts, and the mechanical parts are clamped between the movable positioning plates 9. The two ends of the mechanical parts are fixedly clamped by the movable positioning plates 9, and the spacing between the movable positioning plates 9 can be adjusted, so that this device can use rectangular mechanical parts of various sizes. When the positioning ring 8 and the disassembly ring 7 move with the support mechanism, the movable positioning plate 9 automatically moves away from the mechanical parts, which is convenient for adjusting the clamping position of the parts during the parts processing. In addition, when the mechanical parts need to be flipped, the positioning rings 8 at both ends rotate at the same time to drive the mechanical parts to rotate, and the parts can be processed in multiple angles and dimensions.

[0031] The present invention achieves cooperation between the positioning ring 8 and the disassembly ring 7. The disassembly ring 7 rotates to drive the outer gear 802 to rotate. The rotation of the outer gear 802 drives the movable positioning plate 9 to slide toward the center to clamp the parts. The outer gear 802 continues to rotate and drives the movable positioning plate 9 to spread out. During the rotation of the disassembly ring 7, the supporting mechanism is simultaneously driven to move on the supporting frame 1. Therefore, when the looseness and tightness of the clamping effect on the parts, the clamping position of the device on the parts can be changed, thereby avoiding the influence of the clamping device on the surface of the parts and the trouble of disassembling the parts and re-clamping them. The clamping position can be automatically adjusted to avoid the trouble of re-clamping the parts and improve the clamping efficiency.

[0032] As a further solution of the present invention, the supporting mechanism includes a left mounting frame 4 and a right mounting frame 5, and a locking mechanism 6 is provided on the left mounting frame 4 and the right mounting frame 5. One end of the left mounting frame 4 is slidingly connected to the supporting frame 1, and a driving gear 13 is provided on the left mounting frame 4. A driven tooth 701 is provided on the side of the disassembly ring 7 away from the positioning ring 8, and the driven tooth 701 is meshed with the driving gear 13. A main gear 19 is fixedly connected to one side of the driving gear 13. A threaded rod 2 is fixedly installed on the upper end of the supporting frame 1, and the threaded rod 2 is connected to a threaded ring 20 through threaded rotation. A slave gear 12 is fixedly installed on the threaded ring 20, and the slave gear 12 is meshed with the main gear 19.

[0033] During operation, the locking mechanism drives the active gear 13 to rotate, and the active gear 13 rotates to drive the disassembly ring 7 to rotate through the driven teeth 701 meshing therewith, and the disassembly ring 7 rotates to drive the dense teeth 703 thereon to rotate, and the dense teeth 703 rotate to drive the inner gear 804 to rotate, and the inner gear 804 rotates to drive the outer gear 802 to rotate, thereby controlling the sliding of the movable positioning plate 9 on the positioning ring 8 (when the movable positioning plate 9 spreads to the maximum, the outer gear 802 meshes with the edge of the teeth, and the outer gear 802 continues to rotate and no longer drives the tooth plate 901 to slide), the active gear 13 rotates to drive the main gear 19 to rotate, and the main gear 19 rotates to drive the meshing slave gear 12 to rotate, and the slave gear 12 drives the threaded ring 20 to rotate, and the threaded ring 20 rotates, thereby driving the left mounting frame 4 to slide on the threaded rod 2, thereby changing the positions of the positioning ring 8 and the disassembly ring 7 on the part. After the positioning ring 8 and the disassembly ring 7 move to the specified position, the driving gear 13 rotates in the opposite direction. The rotation of the driving gear 13 drives the disassembly ring 7 to rotate in the opposite direction. The reverse rotation of the disassembly ring 7 drives the outer gear 802 to rotate in the opposite direction. The reverse rotation of the outer gear 802 drives the gear semi-sliding again, so that the movable positioning plate 9 gathers toward the center to fix and clamp the part. When the driving gear 13 stops rotating, the locking mechanism automatically locks the driving gear 13. The position of the locking limit positioning ring 8 and the disassembly ring 7 is locked by the locking mechanism to prevent the positioning ring 8 and the disassembly ring 7 from moving during the part processing process, thereby ensuring the stability of the clamping during the part processing process.

[0034] In the present invention, through the cooperation of the locking mechanism 6 and the driving gear 13, the locking mechanism 6 rotates to drive the driving gear 13 and the main gear 19 to rotate, the driving gear 13 drives the disassembly ring 7 to rotate to control the opening and closing of the movable positioning plate 9, the main gear 19 drives the slave gear 12 to rotate and drives the threaded ring 20 to rotate to control the movement of the positioning ring 8 and the disassembly ring 7 on the support frame 1, and when the locking mechanism 6 stops rotating, the driving gear 13 and the main gear 19 are locked to limit the position movement of the positioning ring 8 and the disassembly ring 7, and at the same time limit the rotation of the threaded ring 20, so as to keep the positioning ring 8 and the disassembly ring 7 stable and maintain the stability of the parts during processing.

[0035] As a further solution of the present invention, a connecting frame 14 is fixedly installed on the left mounting frame 4 and the right mounting frame 5, a disassembly limit groove 702 is provided on the side of the disassembly ring 7 away from the positioning ring 8, an inner connecting ring 805 is fixedly installed on the positioning ring 8, a positioning limit groove 806 is provided on the side of the inner connecting ring 805 close to the disassembly ring 7, a connecting rod 17 is fixedly installed on the connecting frame 14, a limiting member 18 is fixedly connected to the connecting rod 17, the limiting member 18 is slidably connected in the disassembly limit groove 702, an electric telescopic rod 15 is fixedly installed on the connecting frame 14, a limiting block 16 is fixedly installed on the output end of the electric telescopic rod 15, and the limiting block 16 is slidably connected to the positioning limit groove 806.

[0036] During operation, the limit block 16 and the positioning limit groove 806 as well as the limit member 18 and the disassembly limit groove 702 are all connected with external damping, the disassembly limit groove 702 and the positioning limit groove 806 are both dovetail grooves, the limit members 18 on the connecting frames 14 at both ends are all disassembled and slidably connected with the disassembly ring 7, and at the same time, the limit blocks 16 on the connecting frames 14 at both ends are slidably connected with the positioning ring 8 through the positioning limit groove 806, and when the electric telescopic rod 15 is in the natural state, the positioning ring 8 and the disassembly ring 7 are close to each other. At this time, the dense teeth 703 on the disassembling ring 7 are meshed with the inner gear 804. When the electric telescopic rod 15 is extended, the positioning ring 8 is pushed away from the disassembling ring 7. At this time, the meshing of the inner gear 804 on the positioning ring 8 and the dense teeth 703 is disconnected. At this time, the positioning ring 8 can rotate alone. The positioning ring 8 rotates to rotate the parts clamped between the movable positioning plates 9 thereon. The rotation of the positioning ring 8 drives the parts to rotate. The rotation of the parts facilitates multi-angle and multi-dimensional processing of the parts, avoiding blind spots in the viewing angle during processing.

[0037] As a further solution of the present invention, a flip tooth 801 is fixedly connected to the surface of the side of the positioning ring 8 away from the disassembly ring 7, a flip gear 11 is provided on the right mounting frame 5, the flip gear 11 is engaged with the flip tooth 801, a drive motor 10 is fixedly installed on the left mounting frame 4 and the right mounting frame 5, a limit rod 3 is fixedly installed on the support frame 1, and the right mounting frame 5 is slidably connected to the limit rod 3.

[0038] During operation, the electric telescopic rod 15 is extended and pushes the positioning ring 8 close to the flip gear 11, and the driving motor 10 drives the locking mechanism 6 to rotate, and the locking mechanism 6 rotates to drive the flip gear 11 to rotate, and the flip gear 11 rotates through the flip teeth 801 to drive the positioning ring 8 to rotate, and the positioning ring 8 rotates to drive the parts fixed thereon to rotate. When the driving motor 10 stops rotating, the locking mechanism 6 is automatically locked to fix the position of the positioning ring 8. The positioning ring 8 is automatically locked after rotating to a certain angle, driving the rotating and flipping parts for processing. The locking mechanism can prevent the positioning ring 8 from rotating, thereby preventing the parts from being damaged during processing due to the rotation of the positioning ring 8.

[0039] As a further solution of the present invention, the locking mechanism 6 includes an active disk 601 and a locking member 609, the locking member 609 is fixedly mounted on the left mounting frame 4 and the right mounting frame 5, an upper ratchet 605 is provided on one side of the locking member 609, a lower ratchet 606 is provided on one side of the upper ratchet 605, the upper ratchet 605 and the lower ratchet 606 are in opposite directions, a driven disk 604 is rotatably connected inside the locking member 609, a driven shaft 608 is fixedly mounted on the driven disk 604, one eye of the driven shaft 608 extends from the locking member 609 and is fixedly connected to the flip gear 11 and the active gear 13 respectively.

[0040] As a further solution of the present invention, a stopper 602 is fixedly installed on the driven disk 604, and a movable clamping member 607 is arranged in the stopper 602.

The driving motor 10 is fixedly installed on the left mounting frame 4 and the right mounting frame 5, and the output end of the driving motor 10 is fixedly connected to the active disk 601.

[0041] During operation, the driving motor 10 drives the active disk 601 to rotate, and the rotation of the active disk 601 drives the active rod 603 to rotate. The active rod 603 rotates with the active disk 601, and the active rod 603 rotates to squeeze the active clamping piece 607. The active clamping piece 607 is damaged by the active rod 603 in the direction of the driven shaft 608, so that the active clamping piece 607 is disengaged from the lower ratchet 606 and the upper ratchet 605, and the limiting effect of the active clamping piece 607 disappears. The driven disk 604 rotates under the driving action of the active rod 603, and the driven disk 604 rotates to drive the driven shaft 608 to rotate. The driven shaft 608 rotates and then drives the driving gear 13 and the flip gear 11 to rotate.
