Detailed Implementation

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0021] Example 1, as Figures 1-5 As shown, a robot positioning and locking mechanical component includes a sliding rail 11, a sliding seat 13, and a robot arm 2. The sliding seat 13 is slidably connected to the inner side of the sliding rail 11, and the robot arm 2 is fixedly connected to the upper end of the sliding seat 13. The sliding track 11 has an internal cavity 31. A motor 32 is fixedly installed on the inner wall of the cavity 31. A transmission rod 33 is fixedly connected to the output end of the motor 32. A half gear 34 is fixedly connected to the other end of the transmission rod 33. A mounting block 35 is fixedly connected to the inner side of the sliding track 11. A lead screw 36 is rotatably connected to the inner side of the mounting block 35. A full gear 37 is fixedly sleeved on the outer wall of the lead screw 36. A moving block 38 is threadedly connected to the outer wall of the lead screw 36. The sliding seat 13 has an internal cavity A. 317. A movable rod 39 slides through the inner wall of the mounting cavity A317. One end of the movable rod 39 located inside the receiving cavity 31 is rotatably connected to a sliding shaft A310. A movable plate 311 is slidably connected inside the mounting cavity A317 via a guide rail. A V-shaped groove A312 is provided on the upper side of the movable plate 311. The sliding shaft A310 is slidably connected inside the V-shaped groove A312. A locking rod 313 is fixedly connected to one side of the movable plate 311. Multiple locking grooves 314 are provided on the inner wall of the sliding rail 11.

[0022] The upper inner wall of the receiving cavity 31 is provided with a through groove 315. The upper side of the half gear 34 extends to the inner side of the sliding track 11 through the through groove 315. By providing the through groove 315, the upper side of the half gear 34 can pass through the through groove 315 to extend to the inner side of the sliding track 11 and mesh with the full gear 37, so as to realize the transmission of power of motor 32 from the inside of the receiving cavity 31 to the inner side of the sliding track 11. At the same time, the through groove 315 provides clearance space for the rotation of the half gear 34.

[0023] A spring A316 is fixedly connected to the side of the movable plate 311 away from the locking rod 313. The other end of the spring A316 is fixedly connected to the inner wall of the mounting cavity A317. By setting the spring A316, after the movable block 38 is disengaged from the movable rod 39, the movable plate 311 and the locking rod 313 can be automatically pushed back into the locking groove 314 to achieve automatic locking of the sliding seat 13.

[0024] A limiting ring 318 is fixedly sleeved on the outer wall of the moving rod 39. The size of the locking rod 313 matches the locking groove 314. A cover frame 12 is fixedly connected to the upper end of the sliding track 11. By setting the limiting ring 318, when the moving block 38 pushes the moving rod 39 to the right, the limiting ring 318 can contact the inner wall of the mounting cavity A317, so that when the moving rod 39 continues to move, it can drive the entire sliding seat 13 to slide to the right through the limiting ring 318, thereby realizing the displacement adjustment to the right.

[0025] In this embodiment, the moving block 38 pushes the moving rod 39 and the sliding shaft A310 to slide along the V-groove A312, thereby causing the locking rod 313 to disengage from the locking groove 314. When the moving rod 39 continues to move, it drives the sliding seat 13 to slide in the corresponding direction through the end or the limiting ring. After the moving block 38 stops, the locking rod 313 automatically resets and inserts into the locking groove 314 under the action of the spring A316 to complete the locking. This realizes the precise displacement and automatic locking of the sliding seat 13 in any direction on the sliding track 11, effectively avoiding accidental sliding caused by untimely locking during the sliding process.

[0026] In actual use, in the initial state, the locking rod 313 is located inside a locking groove 314, and the bottom of the sliding shaft A310 is located in the middle of the V-shaped groove A312. When it is necessary to slide the sliding seat 13 to the left, the motor 32 is started to drive the transmission rod 33 and the half gear 34 to rotate. When the half gear 34 rotates, it meshes with the full gear 37, driving the lead screw 36 to rotate. The lead screw 36 drives the moving block 38 to move to the left along the lead screw 36. When the moving block 38 moves to the left, it contacts the outer end of the moving rod 39 and pushes the moving rod 39 into the mounting cavity A317. The moving rod 39 drives the sliding shaft A310 to slide along the inclined surface of the V-groove A312. When the sliding shaft A310 slides on the inclined surface, it generates a thrust on the moving plate 311 to move towards the spring A316, pushing the moving plate 311 to overcome the elastic force of the spring A316. The moving plate 311 drives the locking rod 313 to disengage from the locking groove 314, releasing the locking state between the sliding seat 13 and the sliding track 11. When the locking rod 313 is completely disengaged from the locking groove 314, one end of the moving rod 39 will contact the inner wall of the mounting cavity A317. When the moving rod 39 continues to move, it will drive the entire mounting cavity A317 and the sliding seat 13 to move to the left, thereby realizing the sliding displacement of the sliding seat 13 on the sliding track 11. When it is necessary to move the sliding seat 13 to the right, the moving block 38 moves to the right. Similarly, the locking rod 313 will disengage from the locking groove 314. After disengagement, the limiting ring 318 will contact the inner wall of the mounting cavity A317. When the moving block 38 continues to move, it will drive the entire mounting cavity A317 and the sliding seat 13 to slide to the right through the limiting ring 318, thereby realizing the displacement adjustment to the right. When the sliding seat 13 slides to the target position, the moving block 38 stops moving, and the locking rod 313 is reset and inserted into the corresponding locking groove 314 under the action of the spring A316, thus completing the locking.

[0027] Example 2, as Figures 4-7As shown, based on Embodiment 1, an installation cavity B413 is provided inside one side of the sliding track 11. A spring B41 is fixedly connected to the inner wall of the installation cavity B413. A crossbar 42 is fixedly connected to the other end of the spring B41. Tooth plates 43 are fixedly connected to the lower sides of both ends of the crossbar 42. A rotating shaft 44 is rotatably connected to the inner wall of the installation cavity B413. A movable rod 46 and a linkage gear 45 are fixedly sleeved on the outer wall of the rotating shaft 44. A sliding groove 47 is provided in the middle of the movable rod 46. A fixed cylinder 48 is fixedly connected to the inner wall of the installation cavity B413. A sliding rod 49 is slidably connected inside the fixed cylinder 48. A sliding shaft B410 is rotatably connected to the upper end of the sliding rod 49. A protective plate 411 is fixedly connected to the end of the sliding rod 49 away from the fixed cylinder 48.

[0028] The sliding track 11 has movable grooves 412 on both sides, and the movable rod 46 moves through the movable grooves 412. By setting the movable grooves 412, the movable rod 46 is provided with movement space and stroke limit for swinging, so that the movable rod 46 can swing smoothly along the movable grooves 412 under the drive of the linkage gear 45, and drive the slide rod 49 and the protective plate 411 to rise and fall or extend and retract smoothly.

[0029] The crossbar 42 is slidably connected inside the mounting cavity B413. The locking groove 314 is connected to the mounting cavity B413. By connecting the locking groove 314 to the mounting cavity B413, the locking rod 313 can be inserted into the locking groove 314 and further enter the mounting cavity B413 to push the crossbar 42 to move, thereby realizing the linkage control between the locking action of the locking rod 313 and the protective action of the protective plate 411.

[0030] This embodiment realizes that the protective plate 411 automatically extends to form a protective area when unlocking and sliding, and automatically retracts when locking, thereby effectively preventing personnel from accidentally entering the work area and causing collision injuries during the movement of the sliding seat 13, and improving the safety and reliability of equipment operation.

[0031] When the above-mentioned device is used, after the locking rod 313 enters the locking groove 314, it will enter the mounting cavity B413. At this time, the locking rod 313 will push the crossbar 42 to move, and then the crossbar 42 will drive the toothed plate 43 to move outward. Then the linkage gear 45 that meshes with it will rotate inward, and then drive the rotating shaft 44 and the movable rod 46 to swing inward synchronously. When the movable rod 46 swings inward, the sliding groove 47 opened in the middle will push the sliding shaft B410 to slide along the sliding groove 47, and drive the sliding rod 49 to slide inward along the fixed cylinder 48. The protective plate 411 at the upper end of the sliding rod 49 will then approach the sliding track 11. When the locking lever 313 disengages from the locking groove 314, i.e., when the sliding seat 13 is unlocked and ready to slide, the locking lever 313 disengages from the crossbar 42, the spring B41 pushes the crossbar 42 to reset, the crossbar 42 drives the toothed plate 43 to move inward to reset, the linkage gear 45 rotates in the opposite direction to drive the movable rod 46 to swing outward, the sliding shaft B410 slides in the opposite direction along the sliding groove 47, the sliding rod 49 slides downward along the fixed cylinder 48 to reset, and at the same time the protective plate 411 moves outward. During the outward movement of the protective plate 411, its outer end gradually protrudes from the side wall of the sliding track 11, forming a physical isolation barrier when the sliding seat 13 slides, preventing the staff from approaching the working side of the sliding track 11 during the movement of the sliding seat 13, effectively preventing collision injuries caused by personnel accidentally entering the movement area during the sliding of the robot arm 2, and improving the safety and reliability of equipment operation.

[0032] Example 3, as Figure 8 As shown, based on Embodiment 1, mounting grooves 51 are provided on both sides of the movable block 38. A connecting rod A52 is hinged to the inside of the mounting groove 51 via a pin. A connecting rod B53 is hinged to the outer wall of the sliding seat 13. A linkage shaft 54 ​​is rotatably connected to one end of the connecting rod A52 and the connecting rod B53. A connecting shaft 55 is rotatably connected to the bottom of the linkage shaft 54. A sliding shaft C57 is rotatably connected to the inner side of the connecting shaft 55. Receiving grooves 513 are provided at the lower ends of both sides of the sliding seat 13. A lifting plate 58 is slidably connected to the inner wall of the receiving groove 513. A roller 59 is mounted at the bottom of the lifting plate 58. A connecting rod 510 is fixedly connected to the top of the lifting plate 58. A movable plate 511 is fixedly connected to the other end of the connecting rod 510. A V-shaped groove B512 is provided on the outer wall of the movable plate 511. The end of the sliding shaft C57 away from the connecting shaft 55 is slidably connected to the inside of the V-shaped groove B512.

[0033] A limiting block 56 is fixedly connected to the outer wall of the sliding seat 13. The connecting shaft 55 slides through the limiting block 56. By setting the limiting block 56, the sliding of the connecting shaft 55 is guided and limited, ensuring that the connecting shaft 55 can move smoothly in a straight line under the drive of the linkage shaft 54.

[0034] In this embodiment, the V-groove B512 is used to convert the horizontal movement into the downward movement of the lifting plate 58, so that the roller 59 extends out of the receiving groove 57 and contacts the bottom surface of the sliding track 11. This achieves the effect of the roller 59 automatically extending to reduce friction when unlocking and automatically retracting to restore stable support when locking. This effectively reduces the sliding resistance when the sliding seat 13 moves and improves the smoothness of the sliding seat 13 when moving and the stability when locking.

[0035] In the initial state of use, the sliding shaft C57 is located in the middle of the V-groove B512, the lifting plate 58 and the roller 59 are in the retracted state, the roller 59 is higher than the bottom surface of the sliding rail 11, and the sliding seat 13 is fixedly connected to the sliding rail 11 by the locking rod 313. When the moving block 38 moves to the left or right along the lead screw 36, the connecting rod A52 in the mounting slots 51 on both sides of the moving block 38 moves accordingly. The connecting rod A52 drives the connecting rod B53 to swing through the linkage shaft 54. When the linkage shaft 54 ​​moves, it drives the connecting shaft 55 to slide forward or backward along the limit block 56. The sliding shaft C57 on the inner side of the connecting shaft 55 slides from the middle of the V-shaped groove B512 to one side of the inclined surface. Since the left and right sides of the V-shaped groove B512 are symmetrically arranged, no matter whether the sliding shaft C57 slides to the left or right inclined surface, the inclined surface will push the movable plate 511 to move downward through the sliding shaft C57. The movable plate 511 drives the lifting plate 58 to slide downward along the receiving groove 513 through the connecting rod 510. The roller 59 extends out from the receiving groove 513 and contacts the bottom surface of the sliding track 11, thereby reducing friction and allowing the sliding seat 13 to slide smoothly. When the sliding seat 13 slides to the target position and the moving block 38 stops moving, the sliding shaft C57 returns to the middle of the V-groove B512, the lifting plate 58 retracts upward under the action of gravity and spring force, and the roller 59 returns to the receiving groove 513.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
