For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations

[0024] Please refer to Figures 1-5, an embodiment provided by the present utility model: a clamping and feeding device for copper tubes, including a feeding frame 1. The feeding frame 1 is designed with a hollow structure. A first-level screw rod 2 is installed in the feeding frame 1 through bearings. A first-level moving seat 3 is threadedly sleeved on the outer thread of the first-level screw rod 2. One end of the first-level screw rod 2 is fixedly connected to the output shaft of a first-level motor 4. The first-level motor 4 is fixedly installed on the outer wall of the feeding frame 1. A lower connecting seat 7 is fixedly installed on the bottom outer wall of the first-level moving seat 3;

[0025] With this structural design, the first-level motor 4 can rotate. When the first-level motor 4 rotates, it will drive the first-level screw rod 2 to rotate synchronously through the output shaft. Since the first-level moving seat 3 is threadedly connected to the first-level screw rod 2, when the first-level screw rod 2 rotates, the first-level moving seat 3 thereon will drive the mechanism assembly below to perform a linear displacement left and right, so as to meet the free movement effect of the clamping and feeding device of the present utility model in the X-axis direction;

[0026] A Y-axis guiding cylinder 8 is fixedly installed at the bottom end of the lower connecting seat 7. The Y-axis guiding cylinder 8 is perpendicular to the first-level screw rod 2. A guiding groove is opened at the bottom end of the Y-axis guiding cylinder 8. A second-level screw rod 9 is rotatably installed in the guiding groove through bearings. A second-level moving seat 10 is threadedly sleeved on the outer surface of the second-level screw rod 9. A second-level motor 11 is fixedly installed on the outer wall of one end of the Y-axis guiding cylinder 8. The output shaft of the second-level motor 11 is fixedly connected to the second-level screw rod 9;

[0027] As can be seen from the above, when the second-level motor 11 of the present utility model rotates, it will drive the second-level screw rod 9 to rotate synchronously. When the second-level screw rod 9 rotates, the second-level moving seat 10 threadedly connected thereto will perform a forward and backward movement, so as to meet the free movement work of the clamping structure of the present utility model in the Y-axis direction. By cooperating with the movement in the X-axis direction, it has the technical characteristics of dual-axis synchronous movement in the X and Y axes, with high structural movement flexibility and good use performance, and can meet the clamping and feeding work of copper tubes in different areas within the frame.

[0028] Furthermore, a lower connecting plate 12 is fixedly installed at the bottom end of the second-level moving seat 10. Driving cylinders 13 are fixedly installed on both outer walls of the upper surface of the lower connecting plate 12. The driving cylinder 13 is one of a hydraulic cylinder or a pneumatic cylinder. The output end of the driving cylinder 13 is telescopically movably connected to a driving rod. An adjusting plate 14 is fixedly installed between the bottom ends of the two driving rods. Thus, by setting the driving cylinder 13, the adjusting plate 14 at the bottom end can be driven to perform lifting treatment through the driving rod, so as to meet the free movement work of the clamping mechanism in the Z-axis direction, so as to perform clamping and feeding treatment on copper tubes with different stacking heights, meet the use requirements, and reduce the use limitations;

[0029] Further, an adjustment groove is formed in the outer wall of the bottom end of the adjustment plate 14. A positive and negative screw rod 15 is rotatably installed in the adjustment groove through a bearing. Three-stage moving seats 16 are arranged on both sides of the positive and negative screw rod 15. The two three-stage moving seats 16 are respectively in threaded connection with the positive and negative screw rod 15. Among them, in order to ensure normal copper tube clamping work, pneumatic grippers 17 are fixedly installed at the bottom ends of the two three-stage moving seats 16. One end of the positive and negative screw rod 15 and located outside the adjustment plate 14 is fixedly connected with an adjustment handwheel 18;

[0030] With this structural design, the two pneumatic grippers 17 can be lowered under the drive of the drive cylinder block 13, so that the two pneumatic grippers 17 in the lowered state can clamp the two ends of the copper tube to be loaded;

[0031] Above the pneumatic gripper 17 is provided with a three-stage moving seat 16. The adjustment handwheel 18 can be manually rotated. When the adjustment handwheel 18 rotates, it will synchronously drive the positive and negative screw rod 15 to rotate. When the positive and negative screw rod 15 rotates, the two opposite three-stage moving seats 16 on it will move relatively, that is, the two three-stage moving seats 16 will move away from or close to each other (this effect depends on the forward and reverse rotation of the adjustment handwheel 18). When the three-stage moving seat 16 moves relatively, it will drive the pneumatic gripper 17 below to move relatively. At this time, the two pneumatic grippers 17 move closer to or away from each other. In this way, the distance between the two pneumatic grippers 17 can be adjusted. By adjusting the distance between the end clamps, the clamping structure can be adapted to copper tubes of different lengths for clamping work, and can be dynamically adjusted according to the different types and lengths of the clamped objects, with good structural flexibility in use, improving the applicable range of the clamping length dimension and reducing the use limitations.

[0032] In this embodiment, in order to guide and limit the first-stage moving seat 3 and ensure its linear movement and prevent it from rotating synchronously with the first-stage screw rod 2, guide slide rails 6 are fixedly installed on the inner walls of both sides of the loading rack 1. Guide seats 5 are fixedly installed at both ends of the first-stage moving seat 3. The top end of the guide seat 5 is slidably connected with the guide slide rail 6.

[0033] In this embodiment, in order to improve the support stability of the rack, lower support rods 19 are fixedly installed at the four corners of the lower surface of the loading rack 1 by welding. Support pads are fixedly installed at the bottom ends of the lower support rods 19.

[0034] Working principle: The first-level motor 4 provided in the utility model can rotate. When the first-level motor 4 rotates, it will drive the first-level screw rod 2 to rotate synchronously through the output shaft. Since the first-level moving seat 3 is threadedly connected to the first-level screw rod 2, when the first-level screw rod 2 rotates, the first-level moving seat 3 thereon will drive the mechanism assembly below to perform linear displacement left and right, so as to meet the free movement effect of the clamping and feeding device of the utility model in the X-axis direction;

[0035] When the second-level motor 11 provided rotates, it will synchronously drive the second-level screw rod 9 to rotate. When the second-level screw rod 9 rotates, the second-level moving seat 10 threadedly connected thereto will perform forward and backward movement work, so as to meet the free movement work of the clamping structure of the utility model in the Y-axis direction. By cooperating with the movement in the X-axis direction, it has the technical characteristics of co-movement of the X and Y axes, with high structural movement flexibility and good use performance, and can meet the copper tube clamping and feeding work in different areas within the frame;

[0036] At the same time, the driving cylinder body 13 provided can drive the adjusting plate 14 at the bottom to perform lifting treatment through the driving rod, so as to meet the free movement work of the clamping mechanism in the Z-axis direction, so as to perform clamping and feeding treatment on copper tubes with different stacking heights, meet the use requirements, and reduce the use limitations;

[0037] During actual use, the driving cylinder body 13 can drive the two pneumatic clamping jaws 17 to descend through its driving rod. Thus, the two pneumatic clamping jaws 17 can grab both ends of the copper tube to be fed during the descent, completing the clamping work before feeding the copper tube;

[0038] After the pneumatic clamping jaws 17 clamp, the driving cylinder body 13 drives the pneumatic clamping jaws 17 to rise and reset through the driving rod. At this time, the first-level motor 4 and the second-level motor 11 provided can work respectively. The first-level motor 4 and the second-level motor 11 drive the corresponding screw rods to rotate. Thus, the regional movement adjustment of the copper tube is completed through the rotation of the screw rods, so that the pneumatic clamping jaws 17 can move the copper tube from the stacking area to the feeding area after clamping;

[0039] At this time, the pneumatic clamping jaws 17 can release the copper tube, and the copper tube enters the feeding conveyor belt or the processing equipment, so as to complete the automatic clamping and feeding work of the copper tube.

[0040] In summary, the copper tube clamping and loading device of the present utility model can automatically complete the automatic clamping and loading work before copper tube processing. Moreover, the clamping gripper structure can complete free movement in the X, Y, and Z axial directions driven by different transmission structures, with the free displacement characteristic of three-axis simultaneous movement. It can move freely within the loading area of the machine frame, greatly improving the structural movement flexibility of the present utility model. And the drive structures for the three-axis movement are independent of each other, and can perform three-axis linkage or single-axis movement, effectively improving the displacement efficiency and the loading speed. The automatic loading device can replace manual labor for loading, thereby effectively reducing the input of human resources cost, reducing the economic burden of the enterprise, and at the same time reducing the overall processing cost of the copper tube. It has the usage characteristics of saving time and effort, reducing the labor intensity of workers, and is convenient to use;

[0041] Moreover, the gripper clamping mechanism of the present utility model can perform free spacing adjustment work. By adjusting the spacing of the end fixtures, the clamping structure can be adapted to clamp copper tubes of different lengths, and can be dynamically adjusted according to the different lengths of the copper tubes to be clamped. It has good structural usage flexibility, increases the applicable range of the length dimension of the clamping structure, reduces the usage limitations, and has good usage performance.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model.
