[0022] Compared with the prior art, the metal 3D finished product cleaning device provided by the utility model only needs to adjust the opening and closing degree of the opening and closing frame 11 according to the specifications of the finished product 40, so that the area surrounded by the brush assembly 20 changes with the opening and closing frame 11, so that the brush body 22 on the inner side of the brush assembly 20 can fit the surface of the finished products 40 of different specifications, and the support members 12 at both ends of the opening and closing frame 11 are in active contact with the finished product 40, which has a positioning function. The finished product 40 and the opening and closing frame 11 and the brush assembly 20 are relatively displaced through the driving mechanism 30. The brush body 22 cleans the oxide layer on the surface of the finished product 40 and the black carbonized layer caused by the additive, and the nozzle can spray cleaning liquid to remove chemical residues. Therefore, the cleaning device can quickly adjust to fully brush tubular 3D finished products 40 of different specifications, with high cleaning efficiency, relatively simple structure, and not prone to failure.

[0023] At the same time, the two engaging members 21 are synchronously adjusted under the drive of the opening and closing frame 11, so that the brush body 22 can be attached to the surface of the finished products 40 of different specifications.

[0024] It should be noted that if there are still some oxide layers and carbonized layers on the surface of the finished product 40 that have not been cleaned, the finished product 40 can be rotated at a certain angle and cleaned again; the shape of the finished product 40 includes a straight tube, a curved tube, a cylinder, a curved cylinder, an elliptical cylinder or an elliptical tube, and the brush body 22 has a certain plasticity and can be squeezed to fit more closely to the surface of the finished product 40 that has a certain curvature in the length direction. It should be noted that the curvature of the curved tube and curved cylindrical finished products 40 does not exceed 30°.

[0025] In this embodiment, the number of the opening and closing frames 11 is at least one, and may also be two or more.

[0026] In this embodiment, the utility model also includes a clamping piece 13, and two or more of the support members 12 and the clamping piece 13 circumferentially surround the finished product 40. The clamping piece 13 is elastically connected to the opening and closing frame 11 and is in active contact with the finished product 40. Since the clamping piece 13 is elastically connected to the opening and closing frame 11, it can adaptively fit the surface of the finished product 40. The two ends of the opening and closing frame 11 and the clamping piece 13 are distributed in a triangle, and a three-point positioning structure can be formed in the circumferential direction of the finished product 40, so that the position of the brushing component 20 and the finished product 40 is not easy to shift, and the finished product 40 can be cleaned more evenly.

[0027] In this embodiment, please refer to Figure 2 and Figure 3 The opening and closing frame 11 includes two connecting arms 111, a connecting piece 112 hinged to one end of the two connecting arms 111, a connecting rod 113 screwed on the connecting piece 112 and located between the two connecting arms 111, and a spring 114 sleeved on the connecting rod 113; the connecting rod 113 is rotated and adjusted to change the opening and closing degree of the two connecting arms 111; the connecting rod 113 passes through the clamping piece 13 and is movably connected, a limiting piece 115 is provided at the end of the connecting rod 113, and the two ends of the spring 114 are respectively connected to the connecting rod 113 and the clamping piece 13.

[0028] Specifically, the two connecting arms 111 are distributed in a V-shape and are respectively connected to the two ends of the connecting member 112 through a pin to form a hinge structure. The middle position of the connecting member 112 is fixedly connected with a screw sleeve for screwing the connecting rod 113. The two connecting arms 111 extend to the screw sleeve and are hinged. When the connecting rod 113 is rotated, the two connecting arms 111 rotate relative to the connecting member 112 to achieve the opening and closing adjustment of the two connecting arms 111. The elastic deformation of the spring 114 allows the clamping member 13 to move along the axial direction of the connecting rod 113 adaptively. The limiter 115 can prevent the clamping member 13 from detaching from the connecting rod 113. The spring 114 always maintains a certain amount of compression to ensure that the clamping member 13 has a certain force on the 3D printed finished product 40, so that the end of the two connecting arms 111 and the three-point positioning structure formed by the clamping member 13 change accordingly. It should be noted here that the end of the two connecting arms 111 and the clamping member 13 are rollingly connected to the surface of the 3D printed finished product 40 through their respective components, which will be described in detail below.

[0029] In this embodiment, a rotating disk 116 is fixedly provided at the end of the connecting rod 113 close to the connecting member 112 , and the connecting rod 113 can be rotated relatively easily by the rotating disk 116 .

[0030] Furthermore, the limiting member 115 is a limiting nut threaded on the connecting rod 113 or a limiting buckle clamped on the connecting rod 113 .

[0031] Specifically, the connecting rod 113 includes a threaded section in the upper part and a straight section in the lower part. The straight section is sleeved with a spring 114. Two ends of the spring 114 are respectively abutted against the threaded section and the pressing member 13. The end of the connecting rod 113 passing through the lower part of the pressing member 13 is screwed with a limit nut, or an annular groove is opened. The limit buckle is an annular structural member and can be embedded in the annular groove.

[0032] In this embodiment, the pressing member 13 includes: a mounting frame 131 elastically connected to the opening and closing frame 11, and a plurality of cams 132 arranged in parallel on the mounting frame 131. The cams 132 are in rolling connection with the surface of the finished product 40.

[0033] Specifically, the cross-sectional shape of the mounting frame 131 is U-shaped, which can be regarded as the shape of a square tube with one side removed. Its length direction is along the axis of the finished product 40. Two cams 132 are rotatably connected to both ends of the mounting frame 131. Two driving motors 14 are fixed on the outer side of the mounting frame 131. By synchronously driving the cams 132 with the two driving motors 14, the finished product 40 can be driven to move reciprocally, so that the surface of the finished product 40 can be cleaned without relying on an external device to fix the finished product 40, greatly expanding the scope of use and convenience.

[0034] In one embodiment, the driving mechanism includes an articulated robot 31 and a fixing member 32 arranged at the execution end of the articulated robot 31.

[0035] In another embodiment, the driving mechanism includes a plurality of cams 132 arranged on the mounting frame 131. The driving motor 14 is drivingly connected to the cams 132. Specifically, both ends of the finished product 40 are not fixed, but are grasped by the brushing assembly 20, the support member 12 and the pressing member 13. The driving motor 14 drives the cams 132 to drive the finished product 40, and the surface of the finished product 40 can also be washed clean.

[0036] In one embodiment, the fixing member 32 includes two symmetrically arranged limit frames, and the two connecting arms 111 are respectively inserted into the two limit frames and movably connected. The limit frames include two parallel rigid plates 321 and two rollers 322 arranged between the two rigid plates 321. The two connecting arms 111 can move in the area between the two rollers 322. During the adaptation process, the two rollers 322 on each limit frame may contact the corresponding connecting arm 111, which not only plays a limiting role, but also plays a role in reducing friction resistance. The fixing member 32 also includes a mounting plate for the articulated robot 31 for installing the limit frame; the movable area surrounded by the limit frame meets the movable range of the two connecting arms 111 when adjusting, and the two connecting arms 111 are movably connected to the limit frame. The articulated robot 31 can adjust the position of the fixing member 32 according to the specific situation, and control the positioning frame 10 and the brushing assembly 20 at the set position to adapt to the fixed position of the finished product 40.
