Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and more specifically to the wire harness assembly in a 3D printing powder cleaning device. Background Technology

[0002] The 3D printing powder cleaning device is mainly used to remove powder from 3D printed parts, and the cleaning operation is carried out inside the powder tank. To improve the powder cleaning effect and avoid occupying too much space during operation, the powder tank needs to be raised to a preset height when performing the powder cleaning operation.

[0003] Given the complex internal structure of the powder hopper, which contains numerous wires and air pipes, all of these wires and air pipes are connected to a wire harness to improve structural compactness. The wire harness protects, organizes, insulates, and secures these wires and air pipes.

[0004] However, the current wiring harness tube is directly connected at both ends to the lifting slide and the fixed bracket, causing the wire harness tube to move up and down significantly with the lifting slide. Furthermore, during this process, the wire harness tube may come into contact with other components inside the bracket, which can easily lead to damage after prolonged operation. In more severe cases, the wire harness tube may even become stuck, further affecting its normal operation. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a wire harness assembly in a 3D printing powder cleaning device that can effectively protect the wire harness.

[0006] To achieve the above objectives, this utility model can be implemented through the following technical solutions:

[0007] A wire harness assembly in a 3D printing powder cleaning device. The 3D printing powder cleaning device includes a vertically arranged support and a connecting seat for connecting a powder container. The support has a sliding plate that can move vertically along it. The connecting seat is movably connected to the sliding plate. The wire harness assembly is characterized in that it is disposed between the sliding plate and the connecting seat and includes a positioning rod, an elastic connector, and a corrugated tube. The positioning rod is arranged parallel to the support. The corrugated tube includes a connecting end one for connecting to the connecting seat and a connecting end two for connecting to the sliding plate. The middle part of the corrugated tube is an arched deformation section, which is connected to the positioning rod through the elastic connector.

[0008] When the connector is in its initial state, the above-mentioned elastic connector is in a contracted state, and the contracted elastic connector raises the deformation section to its highest point.

[0009] When the connecting seat swings, the above-mentioned elastic connecting member is in a stretched state. The stretched elastic connecting member can cause the deformed section to move down with the slide plate.

[0010] In the wire harness assembly of the aforementioned 3D printing powder cleaning device, the elastic connector includes a housing with an internal cavity. The housing contains a spool, a torsion spring, and a pull rope. The spool is movably connected inside the housing, the torsion spring is connected between the spool and the housing, the inner end of the pull rope is wound around and connected to the spool, and the outer end of the pull rope extends out of the housing and is connected to the deformable section of the corrugated tube. Under the elastic force of the torsion spring, the pull rope tends to be wound into the housing.

[0011] The wire harness assembly in the aforementioned 3D printing powder cleaning device also includes a connecting rope and a hook. The housing is connected to the upper end of the positioning rod via the connecting rope, and the hook is connected to the outer end of the pull rope.

[0012] In the wire harness assembly of the aforementioned 3D printing powder cleaning device, the upper part of the housing has two rope holes, the middle part of the connecting rope passes through the two rope holes, and both ends of the pull rope are fixed to the upper part of the positioning rod.

[0013] In the wire harness assembly of the aforementioned 3D printing powder cleaning device, the hook is spiral-shaped and is fitted onto the deformed section of the corrugated tube.

[0014] In the wire harness assembly of the aforementioned 3D printing powder cleaning device, the positioning rod includes a vertically arranged rod segment one and a horizontally arranged rod segment two. The inner end of the rod segment two is fixedly connected to the upper end of the rod segment one, and the end of the connecting rope is fixedly connected to the outer end of the rod segment two.

[0015] In the wire harness assembly of the aforementioned 3D printing powder cleaning device, the connection between the second rod segment and the first rod segment has a reinforcing rib.

[0016] In the wire harness assembly of the aforementioned 3D printing powder cleaning device, the positioning rod is fixed to the slide plate.

[0017] In the wire harness assembly of the aforementioned 3D printing powder cleaning device, the bracket has an internal cavity, and the aforementioned positioning rod and elastic connector are both located inside the bracket.

[0018] In the wire harness assembly of the aforementioned 3D printing powder cleaning device, there are several elastic connectors, which are evenly distributed along the length of the deformation segment.

[0019] Compared with existing technologies, the corrugated tube in the wire harness assembly of this 3D printing powder cleaning device is used to cover the corresponding wires and air pipes. The corrugated tube can effectively protect and compact the wires and air pipes.

[0020] Because the deformable section of the bellows is connected to the positioning rod via an elastic connector, the elastic connector is stretched as the connecting end of the bellows swings with the connecting seat. In other words, the elastic connector always applies an elastic tension to the deformable section of the bellows, preventing large-amplitude swings at one end of the bellows as the connecting seat swings, and also minimizing contact between the bellows and the inside of the support, resulting in high stability.

Detailed Implementation

[0028] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0029] like Figure 1-5 As shown, the 3D printing powder cleaning device includes a vertically arranged support 1 and a connecting seat 2 for connecting the powder tank 3. The support 1 has a sliding plate 5 that can move up and down along it, and the connecting seat 2 is movably connected to the sliding plate 5.

[0030] The wire harness assembly in this 3D printing powder cleaning device is located between the slide plate 5 and the connecting seat 2, and includes a positioning rod 21, an elastic connector and a bellows 22. The positioning rod 21 is arranged parallel to the bracket 1. The bellows 22 includes a first connecting end 221 for connecting to the connecting seat 2 and a second connecting end 222 for connecting to the slide plate 5. The middle part of the bellows 22 is an arched deformation section 223, and the deformation section 223 is connected to the positioning rod 21 through the elastic connector.

[0031] When the connecting seat 2 is in the initial state, the above-mentioned elastic connecting member is in the contracted state, and the elastic connecting member in the contracted state raises the deformation section 223 to the highest point;

[0032] When the connecting seat 2 swings, the above-mentioned elastic connector is in a stretched state. The stretched elastic connector can cause the deformed section 223 to move down with the slide plate.

[0033] The positioning rod 21 provides sufficient space for the elastic connector to connect, and the deformable section 223 of the bellows 22 is connected to the positioning rod 21 through the elastic connector. Therefore, the deformable section 223 is always subjected to the elastic traction force of the elastic connector.

[0034] In other words, as the connecting end 221 of the bellows 22 moves with the slide plate 5, the deformable section 223 will swing accordingly. At this time, the elastic connector can prevent the deformable section 223 from swinging down quickly, thus minimizing the possibility of the bellows 22 touching the support 1 and effectively improving its stability.

[0035] At the same time, the elastic connector can reduce the swing stroke of the deformation section 223, further preventing the bellows 22 from contacting the support 1.

[0036] The elastic connector includes a housing 24 with an internal cavity. The housing 24 contains a spool 25, a torsion spring 26, and a pull rope 27. The spool 25 is movably connected inside the housing 24. The torsion spring 26 is connected between the spool 25 and the housing 24. The inner end of the pull rope 27 is wound around the spool 25, and the outer end of the pull rope 27 extends out of the housing 24 and is connected to the deformation section of the bellows 22. Under the elastic force of the torsion spring 26, the pull rope 27 tends to be wound into the housing 24.

[0037] Under the elastic force of the torsion spring 26, the spool 25 tends to wind up the pull rope 27. When the bellows 22 swings down, the drag force on the bellows 22 can force the pull rope 27 to overcome the elastic force of the torsion spring 26 and pull the pull rope 27 out of the set length.

[0038] It also includes a connecting rope 28 and a hook 29. The housing 24 is connected to the upper end of the positioning rod 21 via the connecting rope 28, and the hook 29 is connected to the outer end of the pull rope 27.

[0039] The connecting rope 28 allows the housing 24 to be stably and movably connected to the positioning rod 21. This ensures that the housing 24 can adapt to the swinging motion of the deformation section 223.

[0040] The upper part of the housing 24 has two rope holes 241, and the middle part of the connecting rope 28 is passed through the two rope holes 241. Both ends of the pull rope 27 are fixed to the upper part of the positioning rod 21.

[0041] This structure allows the housing 24 to be stably connected to the positioning rod 21.

[0042] The hook 29 is spiral-shaped and is fitted onto the deformed section 223 of the bellows 22.

[0043] This structure can effectively increase the connection area between the hook 29 and the deformation section 223, ultimately ensuring the connection stability of the two.

[0044] The positioning rod 21 includes a vertically arranged rod segment 211 and a horizontally arranged rod segment 212. The inner end of the rod segment 212 is fixedly connected to the upper end of the rod segment 211, and the end of the connecting rope 28 is fixedly connected to the outer end of the rod segment 212.

[0045] The connection between the second pole segment 212 and the first pole segment 211 has a reinforcing rib 30.

[0046] This structure allows the housing 24 to be kept as far away from the rod segment 211 as possible, preventing the housing 24 from touching the positioning rod 21 or the bracket 1.

[0047] Positioning rod 21 is fixed to slide plate 5.

[0048] This structure ensures that the deformation section 223 will not swing excessively. Moreover, during the lifting and lowering of the slide plate 5, the connecting seat 2 and the elastic connector lift and lower synchronously.

[0049] The bracket 1 has a hollow interior, and the positioning rod 21 and the elastic connector are both located inside the bracket 1.

[0050] This improves its structural compactness and prevents parts from being exposed.

[0051] The number of elastic connectors is several, and the elastic connectors are evenly distributed along the length direction of the deformation segment 223.

[0052] Multiple elastic connectors can effectively improve the connection stability of the deformable segment 223.

[0053] The corrugated tube in the wire harness assembly of this 3D printing powder cleaning device is used to sleeve the corresponding wires and air pipes. The corrugated tube can effectively protect and compact the wires and air pipes.

[0054] Because the deformable section of the bellows is connected to the positioning rod via an elastic connector, the elastic connector is stretched as the connecting end of the bellows swings with the connecting seat. In other words, the elastic connector always applies an elastic tension to the deformable section of the bellows, preventing large-amplitude swings at one end of the bellows as the connecting seat swings, and also minimizing contact between the bellows and the inside of the support, resulting in high stability.

[0055] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.

[0056] The technical solutions in the above embodiments have clearly and completely described the content of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
