[0047] The feeding assembly includes two horizontal plates 21. Multiple limiting plates 22 are fixedly installed on the top wall of each horizontal plate 21.

[0051] Each of the two limiting plates 22 is rotatably connected to a rotating shaft 23 on its left and right sides. One end of the rotating shaft 23 located inside the two horizontal plates 21 is rotatably connected to one end of the connecting plate 34, and the other end of the connecting plate 34 is rotatably connected to the connecting shaft 33.

[0052] Optionally, in the above technical solution, the left and right ends of the horizontal plate 21 are respectively provided with inclined plates A24 and B25, the high end of the inclined plate A24 is fixedly connected to the left end of the horizontal plate 21, and the low end of the inclined plate B25 is fixedly connected to the right end of the horizontal plate 21.

[0053] Optionally, in the above technical solution, a side plate 241 is fixedly installed on the left wall of the inclined plate A24, and a 90° angle is formed between the inclined plate A24 and the side plate 241.

[0054] The included angle corresponds to the position between the two polishing wheels 51.

[0055] Optionally, in the above technical solution, the conveying component includes an inverted "U"-shaped support frame 61, which is fixedly installed on the support box 4. Each support frame 61 has two longitudinally arranged rollers 62 rotatably connected inside, and the rollers 62 drive the pipe to move.

[0056] Optionally, in the above technical solution, an auxiliary roller 63 is provided directly above the two rollers 62. The auxiliary roller 63 is rotatably connected to the lifting frame 64, which is in the shape of an inverted "U".

[0057] A threaded hole 60 is provided in the middle of the top wall of the support frame 61. A screw A65 is threaded into the threaded hole 60. One end of the screw A65 located inside the support frame 61 is rotatably connected to the top of the lifting frame 64.

[0058] Optionally, in the above technical solution, the support box 4 is provided with two sets of adjustment components. The adjustment components include a base plate 52 fixedly installed on the support box 4. Two horizontally arranged sliding plates 53 are fixedly installed on the base plate 52. Two sliders 54 are slidably connected to each sliding plate 53. The sliders 54 are fixedly installed on the motor base B55. The polishing wheel 51 is rotatably connected to the motor base B55 on the same side.

[0059] Optionally, in the above technical solution, a guide plate 41 is provided between the two support frames 61. The opening of the guide plate 41 is an inverted trapezoidal structure, and the guide plate 41 provides support for the longitudinal movement of the pipe.

[0060] This invention provides a method for processing metal parts, comprising the following steps:

[0061] S1: Place the multiple metal pipes to be processed on the inclined plate B25;

[0062] S2: Causes the two inner horizontal plates 31 to move simultaneously, driving the pipes to move to the left one by one;

[0063] S3: Push the pipe fittings that have been moved onto the inclined plate A24 and the side plate 241 backward;

[0064] S4: When the pipe fitting is located on the roller 62 on the rear side of the front support frame 61, the auxiliary roller 63 is moved down and the roller 62 is rotated.

[0065] S5: Move the pipe axially so that the part passing through the polishing wheel 51 is polished.

[0066] The length between the two horizontal plates 21 is slightly less than the length of the pipe fitting.

[0067] The length distance between the two auxiliary rollers 63 is slightly smaller than the length of the pipe fitting, so that at least one end of the pipe fitting is pressed down by the auxiliary rollers 63 during the processing of the polishing wheel 51, preventing the pipe fitting from tilting or shifting due to external force.

[0068] Since the inclined plate B25 is set at an angle, the pipes will stick to each other. The movable plate 32, which is composed of triangular plates, has a pointed top structure to separate the pipes on the inclined plate B25 and drive the pipes on the inclined plate B25 to move to the left one by one.

[0069] Furthermore, a motor base A11 is fixedly installed on the top wall of the support base 1, and a motor A12 is fixedly installed on the motor base A11. The output shaft of the motor A12 extends forward and is connected to the synchronous pulley A13. A synchronous pulley B14 is fixedly installed at the front end of a rotating shaft 23. A synchronous belt 15 is connected to both the synchronous pulley A13 and the synchronous pulley B14 for driving the inner horizontal plate 31 to rotate.

[0070] Furthermore, motors B56 are fixedly installed on motor base B55. The output shaft of motor B56 extends forward and is connected to polishing wheel 51. The left polishing wheel 51 rotates counterclockwise and the right polishing wheel 51 rotates clockwise, with the two polishing wheels 51 rotating synchronously.

[0071] Furthermore, a motor mount C66 is fixedly installed on the right side of the support frame 61, and a motor C67 is fixedly installed on the motor mount C66. The output axis of the motor C67 extends to the right and is connected to the roller 62 near the polishing wheel 51.

[0072] Furthermore, a column A26 is fixedly installed on the inclined plate A24, and a column B27 is fixedly installed on the inclined plate B25. The top of the column B27 is higher than the top of the column A26, and the bottoms of the columns A26 and B27 are flush. Both are fixedly installed on the top wall of the support base 1.

[0073] Furthermore, an ear plate 57 is fixedly installed on the base plate 52, and a screw block 58 is fixedly installed on the bottom wall of the motor base B55. A screw rod B59 is internally threaded onto the screw block 58. One end of the screw rod B59 is rotatably connected to the ear plate 57, and the other end is located outside the motor base B55. Twisting the ear plate 57 adjusts the lateral position of the motor base B55.

[0074] Preferably, the front end of the support base 1 is provided with a cylinder seat 71, and a cylinder 72 is fixedly installed on the cylinder seat 71. The movable end of the cylinder 72 extends backward. When the movable end of the cylinder 72 is fully extended, it can push the rear end of the pipe on the inclined plate A24 and the side plate 241 onto the two rollers 62 of the front support frame 61. The longitudinal central axis of the cylinder 72 corresponds to the transverse midpoint of the roller 62.

[0075] In use, place multiple metal pipes to be processed on the inclined plate B25; start the motor A12 to rotate the shaft 23, which in turn drives the two inner horizontal plates 31 to move simultaneously through the connecting plate 34 and the connecting shaft 33.

[0076] The movement path of the horizontal plate 31 is as follows: the horizontal plate 31 moves upward to move the pipe fitting directly opposite from the horizontal plate 21 to the inner horizontal plate 31, the horizontal plate 31 moves left and downward to drop the pipe fitting between the two limiting plates 22 on the left side, and the horizontal plate 31 moves right to reset, thus realizing the step-by-step movement of the pipe fitting to the left one by one.

[0077] The starting cylinder 72 pushes the pipe fitting, which has been moved to the inclined plate A24 and the side plate 241, backward until the pipe fitting is partially located on the roller 62 on the rear side of the front support frame 61; the front auxiliary roller 63 moves down to abut against the pipe fitting, and the rear auxiliary roller 63 moves down to the same position; the motor C67 drives the connected roller 62 to rotate, causing the pipe fitting to move axially; the starting motor B56 rotates the two polishing wheels 51, and the part of the pipe fitting that passes through the polishing wheels 51 is polished;

[0078] After grinding, the pipe continues to move backward under the action of roller 62, pushing the next pipe onto the support box 4 for further grinding.

[0079] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
