[0028] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0029] This application discloses a deburring device for the production of thin-walled copper tubes.

[0030] Reference Figure 1-5The deburring device for thin-walled copper tube production includes a worktable, on which a clamping assembly and a deburring assembly are provided.

[0031] The clamping assembly is used to horizontally clamp the pipe fitting and drive the pipe fitting to rotate. The clamping assembly includes a fixed plate, on which a three-jaw chuck for clamping the pipe fitting is rotatably mounted, and a clearance hole is provided on the fixed plate for the pipe fitting to pass through.

[0032] A drive gear ring is coaxially connected to the outer peripheral wall of the three-jaw chuck. A drive motor is installed on the worktable. A drive gear is coaxially connected to the output shaft of the drive motor. The drive gear meshes with the drive gear ring.

[0033] The drive motor controls the drive gear to rotate, the drive gear drives the drive gear ring to rotate, which in turn drives the three-jaw chuck to rotate, thereby driving the pipe fitting to rotate.

[0034] The deburring assembly includes a mounting bracket, a first grinding roller, and a second grinding roller.

[0035] The mounting bracket is C-shaped and slides towards or away from the pipe fitting via a drive mechanism. The drive mechanism is a sliding cylinder mounted on the worktable, with its piston rod fixedly connected to the mounting bracket. A guide rail is provided on the top surface of the worktable, and a guide groove is provided on the bottom surface of the mounting bracket for the guide rail to pass through. Both the guide rail and the guide groove are dovetail-shaped.

[0036] The first grinding roller is inclined and contacts the inner side of the tube opening, and the second grinding roller is inclined and contacts the outer side of the tube opening. Rotating rods are coaxially connected to both ends of the first grinding roller and both ends of the second grinding roller. A support frame is provided on the mounting frame. The support frame is C-shaped. A rotating motor is fixedly installed at one end of the support frame along its length. A drive wheel is coaxially connected to the output shaft of the rotating motor. A mounting sleeve is coaxially fixedly connected to the end of the drive wheel away from the rotating motor. The rotating rod and the mounting sleeve are detachably connected. After the rotating rod and the mounting sleeve are connected, they remain relatively fixed. A support sleeve is fixedly installed at the other end of the support frame along its length. A limit sleeve is rotatably connected to the inner ring of the support sleeve. The rotating rod and the limit sleeve are detachably connected. After the rotating rod and the limit sleeve are connected, they remain relatively fixed.

[0037] By setting up the first and second grinding rollers, when deburring is needed, the mounting bracket is pushed to the pipe opening by the sliding cylinder for grinding and deburring. This not only saves time and effort and improves efficiency, but also improves the grinding precision. The first grinding roller is set at an angle and contacts the inner side of the pipe opening, and the second grinding roller is set at an angle and contacts the outer side of the pipe opening, so that both the inner and outer sides of the pipe opening can be ground, thus improving the grinding effect.

[0038] A ring-shaped limiting protrusion is coaxially connected to the outer peripheral wall of the limiting sleeve. The limiting protrusion is located in the middle of the axial direction of the limiting sleeve. A limiting ring groove is opened on the inner peripheral wall of the support sleeve to allow the limiting protrusion to rotate. The limiting protrusion rotates in the limiting ring groove to realize the rotatable connection between the limiting sleeve and the support sleeve.

[0039] The inner wall of the limiting sleeve is provided with a strip-shaped limiting groove, which is located on both sides of the radial direction of the limiting sleeve. The length direction of the limiting groove is consistent with the axial direction of the limiting sleeve. A strip-shaped limiting rod is provided on the outer wall of the end of the rotating rod near the limiting sleeve. The limiting rod is inserted into the limiting groove, so that the rotating rod and the limiting sleeve remain relatively fixed after being connected.

[0040] The inner wall of the mounting sleeve has a strip-shaped positioning groove. The length direction of the positioning groove is consistent with the axial direction of the mounting sleeve. A strip-shaped positioning rod is provided on the outer wall of the end of the rotating rod near the mounting sleeve. The positioning rod is inserted into the positioning groove, so that the rotating rod and the mounting sleeve remain relatively fixed after being connected.

[0041] There is a distance s1 between the side of the rotating rod near the drive wheel and the side of the drive wheel near the rotating rod. The depth to which the rotating rod is inserted into the limiting sleeve is s2, where s1 > s2. An installation opening for the rotating rod to pass through is provided on one radial side of the mounting sleeve. The installation opening passes through one axial end of the mounting sleeve. A sealing element is provided at the installation opening. The sealing element includes a limiting post and a clamping block. The limiting post is locked between the rotating rod and the drive wheel. The length of the limiting post is s1. The clamping block is clamped against the outer wall of the rotating rod. A positioning groove two is provided on the inner wall of the clamping block, which is opposite to the positioning groove one. Positioning rods are provided on both radial sides of the rotating rod. One positioning rod is located in the positioning groove one, and the other positioning rod is located in the positioning groove two. An arc-shaped connecting plate is provided on the outer peripheral wall of the clamping block. The two ends of the connecting plate extend radially to the mounting sleeve. The two ends of the connecting plate are fixed to the mounting sleeve by screws.

[0042] When installing the first or second grinding roller, first insert the rotating rod near the mounting sleeve radially into the mounting sleeve, then insert the rotating rod near the limiting sleeve axially into the limiting sleeve, and insert the limiting rod into the limiting groove. Insert the positioning rod into the positioning groove one. After the rotating rod is installed in place, insert the sealing piece into the installation opening, so that the two ends of the limiting post abut against the drive wheel and the rotating rod axially. Then insert the other positioning rod into the positioning groove two. Finally, fix the connecting plate to the mounting sleeve with screws.

[0043] By disassembling and replacing the first and second grinding rollers, the grinding effect on the pipe opening can be guaranteed.

[0044] The implementation principle of a deburring device for thin-walled copper tube production according to an embodiment of this application is as follows:

[0045] Insert the pipe fitting into the three-jaw chuck from the relief port, clamp the pipe fitting with the three-jaw chuck, and then move the deburring component to the pipe opening through the sliding cylinder. Then turn on the drive motor to make the pipe fitting rotate, and then turn on the two rotating motors to make the first grinding roller and the second grinding roller rotate simultaneously, thereby grinding the inner and outer edges of the pipe opening at the same time.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
