[0016] The following is a detailed description of the embodiments of the present utility model in conjunction with the accompanying drawings.

[0017] See also Figures 1 to 5The utility model provides a loading and unloading device for double-head grinding of copper tubes, which includes a machine base 1, on which grinding heads are arranged on both sides of the front and rear of the positioning block, the upper end of the machine base 1 is provided with a longitudinally arranged conveying guide rail 2, a positioning block 5, and a clamping cylinder 8 located on the right side of the positioning block 5, a J-shaped positioning groove is provided on the upper end of the positioning block, a frame member 3 located on the front side of the conveying guide rail 2 is twisted above the machine base 1, a back plate 4 located on the front side of the frame member 3 is arranged on the upper part of the machine base 1 and can be adjusted forward and backward, the back plate can resist the copper tube pushed into the frame member, so as to position the copper tube, an arc-shaped clamping block 9 is provided on the piston rod end of the clamping cylinder 8, and a clamping claw cylinder 7 for clamping the copper tube is provided above the frame member 3 and the positioning block 5, and an avoidance groove for accommodating the clamping claw of the clamping claw cylinder 7 and the clamping block 9 to extend into is transversely provided on the upper end of the frame member 3 and the positioning block 5. The copper tubes arranged on the vibration plate are transported to the conveying rail. The front copper tube is pushed into the frame and held by the plate, so that the copper tube is positioned. Then the left clamping cylinder takes the copper tube and positions it on the positioning block. The right clamping cylinder takes the copper tube to an empty space. The frame will twist, and the frame and the positioning block will not block the clamping of the copper tube, which can speed up the loading and unloading speed. The clamping cylinder then drives the clamping block to clamp the copper tube on the positioning block. The grinding head installed on the machine base can grind both ends of the copper tube.

[0018] Two support columns are arranged on the left and right sides of the upper end of the machine base 1, and a slide rail is arranged transversely between the two support columns. A slider 10 is slidably arranged on the slide rail. A lifting cylinder 6 is symmetrically arranged on the left and right sides of the front end of the slider 10. A clamping cylinder 7 is arranged at the piston rod end of the lifting cylinder 6. A displacement cylinder 11 for driving the slider 10 to move transversely is arranged transversely on the right support column. The lifting cylinder drives the clamping cylinder to descend, and the clamping cylinder clamps the copper tube at the frame and the positioning block. The displacement cylinder drives the copper tube clamped by the clamping cylinder to move right through the slider. At the same time, the lifting cylinder can drive the clamping cylinder to rise (first move to the upper right and tilt, then move to the right, the positioning block and the frame will not block it), which can speed up the loading and unloading speed. The lifting cylinder drives the clamping cylinder to descend and then rise. The copper tube clamped by the clamping cylinder is placed at the positioning block or empty space, and the displacement cylinder drives the clamping cylinder to move left and reset.

[0019] The upper end of the rack 3 is longitudinally provided with a rack groove for receiving the copper tube being transported, and the left and right edges of the upper end of the rack groove are provided with rounded corners. The copper tube transported by the conveying guide rail enters the rack groove and is blocked by the stop plate. After the clamping claw cylinder clamps the copper tube, it can move rightward while rising, and the rack will be twisted, which will not prevent the clamping claw cylinder from clamping and taking away the copper tube.

[0020] The upper end of the machine base 1 is provided with two longitudinally arranged fixed blocks and a vertical block, and the conveying guide rail 2 is provided at the upper end of the two fixed blocks. A rotating shaft keyed to the frame member 3 is rotatably provided between the front fixed block and the vertical block, and a torsion spring connecting the frame member 3 and the vertical block is provided on the outer sleeve of the rotating shaft. The frame member will rotate when the clamping claw cylinder takes away the copper tube, and after the copper tube leaves the frame member, the frame member is reversed and reset by the torsion spring.

[0021] See also Figure 1 , Figure 5 The outer ring of the front end of the rotating shaft is provided with a push rod 12, and the front end of the vertical block is provided with a limiting column 13 for limiting the push rod 12. The frame groove of the frame member is directed upward by the limiting rod and the push rod, so that the frame member is reset when it is twisted.

[0022] The front end of the disc 4 is provided with a slide bar passing through the vertical block, and the slide bar is locked to the vertical block by a locking bolt. The front and rear positions of the disc can be adjusted by the locking bolt to adapt to copper pipes of different lengths.

[0023] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
