[0026] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] Reference Figures 1 to 6As shown, the embodiment of the utility model provides a radiator copper tube assembly and expanding device, including a processing table 1, on which a strip base 2 is installed, and the top of the strip base 2 is provided with a strip groove 21 extending along its length direction; a lower strip block 3 is slidably arranged in the strip groove 21, and the top of the lower strip block 3 is provided with a plurality of lower semicircular grooves 31 equidistantly distributed along its length direction, and the axial directions of the plurality of lower semicircular grooves 31 are consistent with the width direction of the lower strip block 3, and the diameters of the plurality of lower semicircular grooves 31 increase sequentially from left to right; an upper strip block 4 is elastically connected to the top of the lower strip block 3, and guide rods 33 are longitudinally arranged on both sides of the left and right sides of the top of the lower strip block 3, and a circular plate 34 is coaxially arranged on the top of each guide rod 33, and the The diameter of the circular plate 34 is larger than the diameter of the guide rod 33; two circular holes 42 are longitudinally provided at the lower end of the upper strip block 4, and a guide hole 43 is coaxially provided at the top of each circular hole 42, and the diameter of the guide hole 43 is larger than the diameter of the circular hole 42; the two guide rods 33 are respectively slidably arranged in the two circular holes 42, and the two circular plates 34 are respectively slidably arranged in the two guide holes 43; a spring 44 is longitudinally installed in each guide hole 43, and the spring 44 is located above the corresponding circular plate 34. The two guide rods 33 and the guide holes 43 can realize the longitudinal sliding of the upper strip block 4 on the lower strip block 3, and under the elastic force of the spring 44, the upper strip block 4 is elastically supported, so that the upper strip block 4 and the lower strip block 3 are elastically connected;

[0028] The bottom of the upper strip block 4 is equidistantly provided with a plurality of upper semicircular grooves 41 along its length direction, and the plurality of upper semicircular grooves 41 correspond to the plurality of lower semicircular grooves 31 respectively, and each group of corresponding upper semicircular grooves 41 and lower semicircular grooves 31 can be combined to form a complete circular groove, and a chamfer 411 is provided at the end of each upper semicircular groove 41 and lower semicircular groove 31; the strip base 2 is also provided with a position adjustment component 5 for adjusting the position of the lower strip block 3 in the strip groove 21; the rear side of the lower strip block 3 is also provided with a cone 6, and the chamfer 411 matches with the conical surface of the cone 6; the axial direction of the cone 6 is in the same direction as the width direction of the lower strip block 3, and the processing table 1 is also provided with a lateral moving mechanism 7 for driving the cone 6 to move along its axial direction; the processing table 1 is also provided with a lifting mechanism 8 for driving the upper strip block 4 to rise and fall;

[0029] The inner wall of each upper semicircular groove 41 and lower semicircular groove 31 is provided with anti-skid patterns 412 , which can increase the friction coefficient of the upper semicircular groove 41 and lower semicircular groove 31 to the copper tube, thereby preventing the copper tube from sliding in the upper semicircular groove 41 and lower semicircular groove 31 .

[0030] In this embodiment, the staff first determines the model of the copper tube to be processed, and adjusts the position of the lower strip block 3 in the strip base 2 through the position adjustment component 5, so that the lower semicircular groove 31 consistent with the diameter of the copper tube to be processed moves to a position opposite to the cone 6; then the staff takes the copper tube and inserts it into the corresponding lower semicircular groove 31. Since the upper strip block 4 and the lower strip block 3 are elastically connected, there is a certain distance between the upper strip block 4 and the lower strip block 3 when there is no other external force interference on the upper strip block 4. Therefore, the copper tube can be smoothly inserted into the lower semicircular groove 31, and the end of the copper tube slightly extends out of the chamfer 411 at the rear end of the corresponding lower semicircular groove 31. Subsequently, the lifting mechanism 8 is operated to drive the upper strip block 4 to descend, so that the upper strip block 4 fits tightly on the lower strip block 3. , thus the upper semicircular groove 41 and the lower semicircular groove 31 are combined to form a completed circular groove, and the anti-slip groove 412 in the upper semicircular groove 41 and the lower semicircular groove 31 can make the copper tube be pressed in the corresponding upper semicircular groove 41 and the lower semicircular groove 31; at this time, the cone 6 is located at the rear end of the copper tube, and the cone 6 is coaxial with the copper tube, so that the cone 6 is driven by the lateral moving mechanism 7 to move horizontally in the direction of the copper tube, so that the tip of the cone 6 is in contact with the end of the copper tube, and as the cone 6 continues to move, the cone 6 cooperates with the chamfers 411 at the corresponding upper semicircular groove 41 and the lower semicircular groove 31 to squeeze the copper tube, so that the end of the copper tube can be expanded to form a conical surface, and the expansion process of the copper tube is completed, and then the lifting mechanism 8 and the lateral moving mechanism 7 are reset, and the copper tube after processing can be removed by the staff;

[0031] By providing a plurality of upper semicircular grooves 41 on the upper strip block 4 and a plurality of lower semicircular grooves 31 on the lower strip block 3, and the diameters of the plurality of lower semicircular grooves 31 are unequal, the plurality of upper semicircular grooves 41 and the plurality of lower semicircular grooves 31 can be respectively combined to form a plurality of complete circular grooves with unequal diameters through the fitting of the upper strip block 4 and the lower strip block 3. The plurality of circular grooves with unequal diameters can be used as positioning and pressing for copper tubes of different specifications and diameters, and then the lateral movement of the cone 6 and the corresponding chamfer 411 can be squeezed to form a conical expansion at the end of the copper tube, thereby being adaptable to the expansion processing of copper tubes of various specifications.

[0032] Specifically, the position adjustment component 5 includes a positioning rod 51 and a nut 52, the end of the positioning rod 51 is provided with an external thread 511, and the nut 52 is threadedly connected to the external thread 511; the bar base 2 is provided with a through hole 22 along its width direction, and the through hole 22 is located at the bar groove 21; the lower bar block 3 is laterally provided with a plurality of positioning holes 32, and the plurality of positioning holes 32 are equidistantly arranged and at the same height, and the plurality of positioning holes 32 are respectively located below the plurality of lower semicircular grooves 31; the positioning rod 51 is inserted into the through hole 22 and one of the positioning holes 32, and the head end of the positioning rod 51 is provided with a hexagonal knob 53.

[0033] When it is necessary to adjust the position of the lower strip block 3, the staff first rotates the hexagonal knob 53 to remove the positioning rod 51 and the nut 52 from the strip base 2. Then, the staff can move the lower strip block 3 along the strip groove 21. During this process, the upper strip block 4 will also move with the lower strip block 3. When the appropriate lower semicircular groove 31 is facing the cone 6, at this time, the positioning hole 32 below the lower semicircular groove 31 also corresponds to the through hole 22 on the strip base 2. Then the staff inserts the positioning rod 51 into the positioning hole 32 and the through hole 22, and locks the positioning rod 51 on the strip base 2 through the nut 52, so that the lower strip block 3 is fixed in the strip groove 21 on the strip base 2, and then the position adjustment of the lower strip block 3 is completed. In this way, according to the actual situation, the lower semicircular grooves 31 of different diameters are facing the cone 6, which can cope with the compression positioning of copper tubes of different specifications and diameters.

[0034] Specifically, the lateral moving mechanism 7 includes two linear guide rails 71 installed transversely on the processing table 1, and the length directions of the two linear guide rails 71 are consistent with the axial direction of the cone 6; a sliding plate 72 is longitudinally provided above the two linear guide rails 71, and the cone 6 is installed on the sliding plate 72, and two sliding grooves 721 are provided at the bottom of the sliding plate 72, and the two sliding grooves 721 are respectively slidably matched with the two linear guide rails 71;

[0035] The lateral moving mechanism 7 also includes a mounting frame 73 and a first linear drive source 74. The mounting frame 73 is arranged on the processing table 1. The first linear drive source 74 is horizontally installed on the mounting frame 73. The driving direction of the first linear drive source 74 is consistent with the axial direction of the cone 6. The output shaft of the first linear drive source 74 is fixedly connected to the sliding plate 72.

[0036] The operation of the first linear drive source 74 can drive the sliding plate 72 to slide on the two linear guide rails 71, thereby pushing the cone 6 to move toward or away from the lower strip block 3. In this way, through the lateral movement of the cone 6, it can be extruded and matched with the chamfers 411 at the corresponding upper semicircular grooves 41 and the lower semicircular grooves 31 to complete the expansion processing of the copper tube end.

[0037] Specifically, the lifting mechanism 8 includes a vertical plate 81 installed on the processing table 1, a horizontal plate 82 is horizontally provided on the top of the vertical plate 81, and a second linear drive source 83 is longitudinally installed on the lower end of the horizontal plate 82; when the second linear drive source 83 is in the upper limit position, the upper strip block 4 is supported by the spring 44, and there is a certain distance between the upper strip block 4 and the lower strip block 3, and the second linear drive source 83 has no contact with the upper strip block 4, and when the second linear drive source 83 is in the lower limit position, it can drive the upper strip block 4 to descend and fit on the lower strip block 3, so that multiple upper semicircular grooves 41 and multiple lower semicircular grooves 31 can be combined to form multiple complete circular grooves, and multiple circular grooves of unequal diameters can be used to position and press copper tubes of various diameters.
