[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0033] like Figure 1 As shown, the present invention provides an automatic flat-end deburring system for copper tubes, comprising a flat-end mechanism group for deburring the flat-ends of both ends of the copper tubes, a support mechanism 2 for supporting the flat-ends, and an alignment mechanism 3 for aligning the copper tubes and then deburring the flat-ends;

[0034] The flat-mouth mechanism group includes two flat-mouth mechanisms arranged in the front-to-back direction, and at least one of the two flat-mouth mechanisms can move forward and backward to adjust the distance between the front flat-mouth mechanism 11 and the rear flat-mouth mechanism 12;

[0035] The support mechanism 2 is arranged between the flat-mouth mechanism groups; the support mechanism 2 includes a plurality of support frames 21 arranged in parallel in the front-to-back direction; the plurality of support frames 21 can move between the flat-mouth mechanism groups, so that the spacing between the frontmost and rearmost support frames changes.

[0036] The principle of the present invention is that the two flat-end mechanisms arranged in front and back respectively perform flat-end deburring for the two ends of the copper tube. At least one of the two flat-end mechanisms can move forward and backward, thereby changing the distance between the two to adapt to copper tubes of different lengths. In addition, the support mechanism 2 in the present invention is also composed of a plurality of separate support frames 21. The distance between the support frames 21 can be adjusted, so that the length of the support can also be changed to adapt to copper tubes of different lengths.

[0037] In order to realize the movement of the flat-mouth mechanism and the support frame 21, a frame 13 is provided in this embodiment, and a track is provided on the frame 13; the front flat-mouth mechanism 11 located at the front end of the copper tube is fixedly arranged, and the rear flat-mouth mechanism 12 located at the rear end of the copper tube is movably arranged; the fixed flat-mouth mechanism is installed at the front end of the track, and the movably arranged flat-mouth mechanism is installed on the track and can move forward and backward with the track; the support frame of the support mechanism is arranged on the track between the two flat-mouth mechanisms.

[0038] In order to drive the movable flat-mouth mechanism and the support frame to move, a rack 14 arranged parallel to the track may also be included, and the movable flat-mouth mechanism and the support frame 21 are both provided with a gear 214 meshing with the rack 14, and the movable flat-mouth mechanism and the support frame 21 are driven to move by the rotation of the gear 214.

[0039] Of course, other driving modes are also possible. For example, in some embodiments, a scissor frame can be provided between the support frames 21 to drive the support frames to move. The spacing between the support frames claimed in the present invention is adjustable, and the specific driving mode is not limited.

[0040] More specifically, the alignment mechanism 3 in the present invention includes a plurality of rollers 31 arranged in the front and rear directions for carrying copper tubes, and the rollers 31 can transport the copper tubes to the front end or the rear end; it also includes two front and rear alignment cylinders 32 arranged on the same straight line as the rollers 31, the two alignment cylinders 32 are arranged opposite to each other, and baffles are arranged at the ends of their piston rods; the two alignment cylinders are respectively arranged on the front and rear flat-mouth mechanisms.

[0041] The copper tube from the previous process is automatically rolled onto the roller 31 by the gravity of the copper tube through the loading ramp 5. The roller 31 rotates to transport the copper tube to one end. After being transported to the right place, the copper tube can be positioned by the baffles extended by the two alignment cylinders 32, so that each copper tube loaded is located at the same position, which is convenient for the subsequent flat end deburring work.

[0042] In order to transfer the copper tube, in this embodiment, a movable bracket 212 for placing the copper tube is provided on the support frame 21; the roller 31 is arranged on the side of the support frame 21 and corresponds to the support frame 21 one by one; the movable bracket 212 can make an elliptical motion on the vertical surface to transfer the copper tube on the roller 31 to the flat-end mechanism group for flat-end deburring.

[0043] The rollers 31 are arranged on the support frame 21 and move with the support frame 21 . The spacing between the rollers can also be adjusted to accommodate copper tubes of different lengths.

[0044] In this embodiment, the copper tube needs to be gradually translated so as to switch between the alignment station, the flat-end deburring station and other stations. In this embodiment, a movable bracket 212 is used to complete the above transfer work. Specifically, the support frame 21 includes a fixed plate 211, and a rotatable cam arm is provided on the fixed plate 211; the movable bracket 212 is fixed on the cam arm and performs elliptical motion with the rotation of the cam arm.

[0045] The height positions of the alignment station and the flat-end deburring station are between the highest position and the lowest position of the movable bracket 212. When the movable bracket 212 performs an elliptical motion, it can rise to lift the copper tube on the alignment station and move it to the flat-end deburring station. When it moves to the flat-end deburring station, it starts to descend and delivers the copper tube to the flat-end deburring station. Similarly, the copper tube can also be transferred from the flat-end deburring station to the subsequent station in the same manner.

[0046] The flat-end mechanism in this embodiment includes a clamping device for clamping and fixing the copper tube and a flat-end device for flat-end deburring the end of the copper tube; the clamping device includes two clamping blocks 113 arranged in the left and right directions; the flat-end device includes a chamfering knife 111 that can rotate along the end face of the copper tube; the flat-end device can move in the forward and backward directions.

[0047] The movable bracket 212 transfers the copper tube to between the two clamping blocks 113. The two clamping blocks 113 are close to each other to clamp the copper tube stably. At this time, the flat-end device moves forward and uses the rotating chamfering knife 111 to chamfer the end of the copper tube, thereby completing the flat-end deburring work of the copper tube.

[0048] After the alignment mechanism 3 is aligned, the transfer of the movable bracket 212 may cause the copper tube to be displaced in the front-to-back direction, so that the working position of the chamfering cutter 111 changes when the flat edge is deburred. In order to avoid the above situation, the flat edge mechanism in this embodiment also includes an alignment detection device, which includes a pressure sensor 112 arranged side by side with the chamfering cutter 111; and also includes a base, and the flat edge device and the alignment detection device are installed on the base and can move forward and backward and left and right on the plane with the base.

[0049] After the copper tube is clamped by the clamping device, the alignment detection device moves in the left and right directions to be in the same straight line with the copper tube, and then moves forward to be in position and abut against the end of the copper tube. Since the movement position of the alignment detection device is set, the pressure sensor 112 will sense different pressures due to the different positions of the copper tube. Therefore, the above method can be used to detect whether the copper tube is in place. If the pressure detected by the pressure sensor 112 exceeds the threshold, it is considered that the copper tube is too far forward; if the pressure detected by the pressure sensor is less than the threshold, it is considered that the copper tube is too far back. In both of the above situations, the deburring work on the flat end of the copper tube should be stopped, and manual corrections should be reminded through alarms or other means.

[0050] After the detection is completed, the alignment detection device retreats and moves horizontally under the drive of the base, so that the flat-end device is aligned with the copper tube, and then moves forward under the drive of the base to perform flat-end deburring.

[0051] In this embodiment, a purging station is also provided after the flat-end deburring station. Specifically, a fixed bracket 213 is provided on the side of the support frame 21 opposite to the roller 31; a sliding ramp is provided on the side of the fixed bracket 213; the movable bracket 212 can transfer the copper tube to the fixed bracket 213 for temporary storage, and transfer the copper tube on the fixed bracket 213 to the unloading ramp. It also includes a blowing mechanism 4 located on the same straight line as the fixed bracket, and the blowing mechanism 4 can extend to the end of the copper tube to blow air into the copper tube; it also includes a copper scrap collection box arranged opposite to the blowing mechanism.

[0052] The copper tube after flat-end deburring is transferred to the fixed bracket 213. The air blowing mechanism 4 extends into the copper tube to blow air inside the copper tube, and the copper chips in the copper tube are blown to the copper chip collecting box at the other end to be collected.

[0053] In this embodiment, the material discharge ramp is composed of a plurality of inclined support rods 22 fixed on the support frame 21. The support rods 22 move with the support frame 21 and can also adapt to copper pipes of different lengths.

[0054] In addition, a material receiving rack 6 is provided on one side of the material unloading ramp, and the material receiving rack 6 is provided with a plurality of protective belts from the front to the back, and the two ends of the protective belts are connected to springs. In some embodiments, the two ends of the protective belts are directly suspended above the frame by springs. In some embodiments, the two ends of the protective belts pass around the fixed pulley located above the frame and are connected to the springs located below the frame.

[0055] The purpose of using springs to connect the protective belt and the frame is to adjust the height of the protective belt by the weight of the copper tube. When there are fewer copper tubes, the protective belt is located higher, so that the height difference of the copper tube rolling down from the unloading ramp becomes smaller. As the number of copper tubes increases, the protective belt is pressed down to provide more loading space.

[0056] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention, and the protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
