[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 5 As shown, a closing frame positioning and locking mechanism includes a positioning and locking mechanism body 1. Two symmetrically distributed horizontal plates 2 are fixedly connected to the bottom of the positioning and locking mechanism body 1. Two sliding rods 3 are fixedly connected between the two horizontal plates 2. Two symmetrically distributed locking clamps 4 are slidably connected to the outer surfaces of the two sliding rods 3. The locking clamps 4 are used to lock the closing frame. A U-shaped plate 5 is fixedly connected to the bottom of the positioning and locking mechanism body 1.

[0026] A double-headed rotating shaft seat 6 is rotatably installed at the bottom of the U-shaped plate 5. Two locking clamping plates 4 and the double-headed rotating shaft seat 6 are rotatably connected to a rotating plate 7. A connecting plate 15 is fixedly installed inside the main body 1 of the positioning and locking mechanism. A gear rod 16 is rotatably connected to the upper side of the connecting plate 15. Two T-shaped limiting plates 17 are fixedly connected to the bottom of the main body 1 of the positioning and locking mechanism. A rack 18 is slidably connected to each of the two T-shaped limiting plates 17. A positioning clamping plate 19 for locking the closing frame is fixedly provided on the upper side of each of the two racks 18. Through the setting of the T-shaped limiting plates 17, the movement trajectory of the rack 18 can be guided by the T-shaped limiting plates 17. In this way, the positioning clamping plate 19 on the rack 18 can be smoothly adjusted and moved to facilitate the positioning and closing of the frame.

[0027] Rubber strips 14 are evenly connected to the other side of the two locking clamps 4, and rubber strips 20 are evenly connected to one side of the two positioning clamps 19.

[0028] Each of the two locking clamps 4 has a fixed block 9 on one side. The interior of each of the two fixed blocks 9 is rotatably connected to a T-shaped movable plate 10. Each of the two T-shaped movable plates 10 has two first bolts 11 threadedly connected to one side. Each of the four first bolts 11 has a round seat 12 fixedly connected to one side for positioning the upper part of the closing frame. The round seat 12 can be used to position the upper part of the closing frame, so that the entire closing frame can be fully positioned and locked, preventing the closing frame from loosening and affecting subsequent processing.

[0029] Both racks 18 mesh with the gear rod 16. A second servo motor 21 is fixedly installed on the lower side of the connecting plate 15, and the output shaft of the second servo motor 21 is fastened to the gear rod 16.

[0030] One side of the first bolt 11 passes through the T-shaped movable plate 10 and extends to the other side of the T-shaped movable plate 10. One side of each of the two T-shaped movable plates 10 is threaded with a second bolt 13 for fixing the T-shaped movable plate 10. One side of the second bolt 13 passes through the T-shaped movable plate 10 and extends to the top of the locking clamp 4. By setting the second bolt 13, rotating the second bolt 13 can disengage it from the locking clamp 4, so as to release the limitation on the T-shaped movable plate 10 and rotate the T-shaped movable plate 10 to one side of the locking clamp 4, thus avoiding the removal of the closing frame.

[0031] The lower side of the U-shaped plate 5 is fixedly connected to the first servo motor 8. The output shaft of the first servo motor 8 is fastened to the double-headed rotating shaft seat 6. The model of the first servo motor 8 and the second servo motor 21 is SMBL-60P.

[0032] The working principle of the closing frame positioning and locking mechanism provided by this utility model is as follows:

[0033] By placing the various components of the merging frame flat onto the main body 1 of the positioning and locking mechanism, and then driving the output shaft of the first servo motor 8 to rotate the double-headed rotating shaft seat 6, the two rotating plates 7 at the double-headed rotating shaft seat 6 can rotate synchronously, pulling the two locking clamps 4 on the two slide rods 3 to move towards each other, so that the two locking clamps 4 can be positioned at both ends of the merging frame. Then, driving the output shaft of the second servo motor 21 to rotate the gear rod 16, the gear rod 16 can drive the two racks 18 on the two T-shaped limit plates 17 to move towards each other, so that the two racks 18 can drive the two positioning clamps 19 to be positioned at the other ends of the merging frame, so as to securely lock the merging frame around all sides, preventing the merging frame from loosening and reducing the stability during positioning, improving the convenience of using the positioning and locking mechanism. At the same time, the cooperation of the two locking clamps 4 and the two positioning clamps 19 can also position merging frames of different sizes, with good applicability.

[0034] By rotating the two T-shaped movable plates 10 above the locking clamping plate 4, and then tightening the four second bolts 13 in sequence, the second bolts 13 are fixed on the locking clamping plate 4 to fix the position of the two T-shaped movable plates 10. Then, the four first bolts 11 are tightened in sequence to drive the four round seats 12 to be positioned above the closing frame, which is used to further lock the closing frame and ensure the stability of the closing frame. Subsequently, the rubber strip 14 on the locking clamping plate 4 and the rubber strip 20 on the positioning clamping plate 19 can increase the friction with the closing frame so that the closing frame can be stably and reliably positioned and locked.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
