Description

Technical Field

[0001] This application relates to the field of machine tool panel mounting technology, and in particular to a rotating wiring node for a machine tool panel mounting rod. Background Technology

[0002] There are generally two installation methods for CNC machine tool control panels: one is direct integration into the machine tool, and the other is mounting the panel externally via a mounting rod. Generally, control panels mounted externally via a mounting rod can have their position and angle changed by rotating or extending the mounting rod. The panel is connected to the machine tool via a wiring harness, which is usually located inside the mounting rod and routed internally. During rotation, the wiring harness is prone to friction with the internal stiffening structure of the mounting rod, leading to wear. Furthermore, a lack of proper wiring harness positioning can cause it to become entangled inside the mounting rod.

[0003] Therefore, a reasonable wiring structure needs to be set at the rotation node of the mounting rod to avoid wire wear and tangling during rotation. Utility Model Content

[0004] Therefore, it is necessary to provide a rotating wiring node for a machine tool panel mounting rod, and the specific technical solution is as follows.

[0005] A rotating wiring node for a machine tool panel mounting rod includes:

[0006] The connector is provided with a cable inlet and a rotating shaft cavity; the cable inlet is connected to the rotating shaft cavity;

[0007] A wire clamping plate is installed at the bottom of the rotating shaft cavity; the wire clamping plate is provided with multiple through holes for accommodating wire harnesses to pass through, and the multiple through holes are arranged around the axis of the rotating shaft cavity;

[0008] The rotating shaft has a cable routing cavity extending along the axial direction inside, and a cable outlet is provided on the rotating shaft, which communicates with the cable routing cavity; the rotating shaft is rotatably inserted into the rotating shaft cavity, and a receiving space is formed between the bottom of the rotating shaft and the cable clamping plate;

[0009] The wiring structure is installed inside the wiring cavity; the wiring structure includes multiple sets of wire clips, each set of wire clips corresponds to a through hole, and the wire clips form a spiral arrangement around the axis of the wiring cavity.

[0010] Furthermore, the wiring structure includes a connecting plate, a connecting rod, and multiple positioning rings; the connecting plate is connected to the end of the rotating shaft; the connecting rod is connected to the connecting plate, and the multiple positioning rings are arranged at intervals along the axial direction of the wiring cavity, and each positioning ring is connected to the connecting rod; the inner ring of the positioning ring is provided with multiple slots, and the corresponding slots on each positioning ring are connected to form a wire clamp group.

[0011] Furthermore, the slot includes an arc portion and an opening portion; the spacing between the opening portions is smaller than the diameter of the arc portion.

[0012] Furthermore, a partition block is formed between two adjacent slots, and the partition block protrudes along the inner ring of the positioning ring in the axial direction; the arc portion is located on the side of the partition block closer to the positioning ring, and the opening portion is located on the side of the partition block away from the positioning ring.

[0013] Furthermore, a bearing is provided inside the rotating shaft cavity, and a stepped surface is provided inside the rotating shaft cavity; a pressure plate is provided at the end of the bearing away from the wire clamping plate, and the pressure plate is connected to the connecting seat and presses the bearing tightly onto the stepped surface.

[0014] Furthermore, it also includes a connecting rod, which has a wiring channel inside; the connecting rod is connected to the rotating shaft, and the wiring channel is connected to the outlet.

[0015] Furthermore, the end of the connecting rod is provided with a connecting part, and the connecting part has a groove. The rotating shaft is inserted into the groove and connected to the connecting part by a screw.

[0016] Furthermore, the end of the connecting rod is provided with an abutment surface, which is located below the connecting part; the abutment surface slides against the outer surface of the connecting seat, and the abutment surface is an arc surface arranged coaxially with the rotating shaft cavity.

[0017] Furthermore, the wiring harness within the accommodating space is arranged in a curved manner.

[0018] Furthermore, the outer contour of the wire clamping plate is non-circular; the bottom of the rotating shaft cavity is provided with a mounting groove that matches the outer contour of the wire clamping plate; the wire clamping plate is placed in the mounting groove, and the mounting groove restricts the rotation of the wire clamping plate.

[0019] Beneficial effects: The rotating wiring node for a machine tool panel mounting rod provided by this utility model limits the wiring harness through a wire clamping plate and a wiring structure, and reserves a space between the rotating shaft and the wire clamping plate. When the rotating shaft rotates, the wiring harness changes its bending angle in the reserved space, avoiding direct friction between the wiring harness and the end face of the rotating shaft, thus reducing the wear of the wiring harness. Furthermore, the path of the wire clamping group is set to a spiral shape, and the wiring harness in the wiring cavity is also curved, reducing the bending angle of the wiring harness at the end of the wiring cavity, making the bending smoother and reducing the impact on the wiring harness. The wire clamping plate and the wiring structure can limit each wiring harness separately, which can prevent the wiring harness from tangling. Attached Figure Description

[0041] Example

[0042] Reference Figures 1-8 As shown, this embodiment discloses a rotating wiring node for a machine tool panel mounting rod, including a connecting seat 1, a wire clamping plate 2, a rotating shaft 3, and a wiring structure 4. The connecting seat 1 has a wire inlet 11 and a rotating shaft cavity 12; the wire inlet 11 communicates with the rotating shaft cavity 12. During installation, the connecting seat 1 is connected to the machine tool, allowing the wire harness 6 to pass through the wire inlet 11 and enter the rotating shaft cavity 12. (Refer to...) Figure 2 and Figure 3 As shown, the wire clamping plate 2 is installed at the bottom of the rotating shaft cavity 12. The wire clamping plate 2 has multiple through holes 21 for accommodating wire harnesses 6, and these through holes 21 are arranged around the axis of the rotating shaft cavity 12. The wire harnesses 6 inside the rotating shaft cavity 12 pass through the through holes 21; specifically, the wire harnesses 6 can be passed through the through holes 21 individually. It should be noted that, referring to… Figure 4 As shown, in order to prevent the edge of the through hole 21 from cutting the wire harness 6, a rubber coil 22 can be sleeved on the through hole 21 so that the wire harness 6 passes through the rubber coil 22, thus providing protection for the wire harness 6.

[0043] Specifically, refer to Figure 8 As shown, the rotating shaft 3 has a cable routing cavity 31 extending along its axial direction inside, and a cable outlet 32 ​​on the rotating shaft 3, which communicates with the cable routing cavity 31. The rotating shaft 3 is rotatably inserted into the rotating shaft cavity 12, forming a receiving space between the bottom of the rotating shaft 3 and the cable clamping plate 2. (Refer to...) Figure 5 As shown, the wiring structure 4 is installed inside the wiring cavity 31; the wiring structure 4 includes multiple sets of wire clips, each set of wire clips corresponding to a through hole 21, and the wire clips form a spiral arrangement around the wiring cavity 31. The wire harness 6 inside the machine tool enters the spindle cavity 12 through the inlet 11, as shown in the figure. Figure 7 As shown, the wire harness 6 passes through the through hole 21 on the wire clamp plate 2 and enters the receiving space, so that the wire harness 6 is arranged in a curved shape in the receiving space, leaving a certain amount of slack for the wire harness 6 to rotate with the rotating shaft 3. The wire harness 6 in the receiving space is threaded one-to-one into each wire clamp group, and is arranged in a spiral shape along the path of the wire clamp group, reducing the degree of bending of the wire harness 6 at the end face of the wiring structure 4.

[0044] This embodiment provides a rotating wiring node for a machine tool panel mounting rod. The wiring harness 6 is limited by a wire clamping plate 2 and a wiring structure 4. A pre-reserved space is provided between the rotating shaft 3 and the wire clamping plate 2, allowing the wiring harness 6 to change its bending angle within this space as the rotating shaft 3 rotates. This prevents the wiring harness 6 from directly rubbing against the end face of the rotating shaft 3, reducing wear on the wiring harness 6. Furthermore, the path of the wire clamping assembly is set to a spiral shape, and the wiring harness 6 within the wiring cavity 31 also exhibits a certain degree of curvature, reducing the bending angle of the wiring harness 6 at the end of the wiring cavity 31, making the bending smoother and minimizing the impact on the wiring harness 6. The wire clamping plate 2 and the wiring structure 4 can individually limit the movement of each wiring harness 6, preventing tangling.

[0045] Specifically, refer to Figure 5 As shown, the wiring structure 4 includes a connecting plate 41, a connecting rod 42, and multiple positioning rings 43. The connecting plate 41 is connected to the end of the rotating shaft 3. The connecting rod 42 is connected to the connecting plate 41. The multiple positioning rings 43 are arranged at intervals along the axial direction of the wiring cavity 31, and each positioning ring 43 is connected to the connecting rod 42. The inner ring of each positioning ring 43 is provided with multiple slots 44, and the corresponding slots 44 on each positioning ring 43 are connected to form a wire clamping group. This allows the wiring structure 4 to be separated from the rotating shaft 3, and the wiring structure 4 forms a hollow structure, which facilitates the insertion of the wire harness 6 into the slots 44 before installing the wiring structure 4 into the wiring cavity 31 of the rotating shaft 3.

[0046] Specifically, the slot 44 includes an arcuate portion 45 and an opening portion 46; the spacing of the opening portions 46 is smaller than the diameter of the arcuate portion 45. This facilitates the insertion of the wire harness 6 into the arcuate portion 45, while the opening portions 46 prevent the wire harness 6 from falling out.

[0047] Specifically, refer to Figure 6 As shown, a partition block 47 is formed between two adjacent slots 44. The partition block 47 protrudes along the inner ring of the positioning ring towards the axis. The arc portion 45 is located on the side of the partition block 47 closer to the positioning ring 43, and the opening portion 46 is located on the side of the partition block 47 away from the positioning ring 43. When the wire harness 6 is inserted, the wire harness 6 presses against the partition block 47, causing the partition block 47 to deform toward the adjacent slot 44, thereby facilitating the insertion of the wire harness 6 into the slot 44.

[0048] Reference Figure 3As shown, a bearing 14 is provided inside the rotating shaft cavity 12, and a stepped surface 13 is provided inside the rotating shaft cavity 12; a pressure plate 15 is provided at the end of the bearing 14 away from the wire clamping plate 2, and the pressure plate 15 is connected to the connecting seat 1 and presses the bearing 14 onto the stepped surface 13. It should be noted that, in order to prevent the wire clamping plate 2 from rotating with the wire harness 6 inside the rotating shaft cavity 12, the outer contour of the wire clamping plate 2 is non-circular; the bottom of the rotating shaft cavity 12 is provided with a mounting groove that matches the outer contour of the wire clamping plate 2; the wire clamping plate 2 is placed in the mounting groove, and the mounting groove restricts the rotation of the wire clamping plate 2. The wire clamping plate 2 can also be installed at the bottom of the rotating shaft cavity 12 using screws.

[0049] Specifically, continue to refer to Figure 1 As shown, it also includes a connecting rod 5, which has a wiring channel inside; the connecting rod 5 is connected to the rotating shaft 3, and the wiring channel is connected to the outlet 32. The wire harness 6 in the rotating shaft cavity 12 enters the connecting rod 5 through the outlet 32.

[0050] Specifically, the end of the connecting rod 5 is provided with a connecting part 51, and the connecting part 51 has a groove. The rotating shaft 3 is inserted into the groove and connected to the connecting part 51 by a screw. The screw passes through the top of the connecting part 51 and connects to the rotating shaft 3, which facilitates the assembly of the rotating shaft 3.

[0051] Specifically, the end of the connecting rod 5 is also provided with an abutment surface 52, which is located below the connecting part 51. The abutment surface 52 slides against the outer surface of the connecting seat 1, and the abutment surface 52 is an arc surface arranged coaxially with the rotating shaft cavity 12. By abutting against the outer surface of the connecting seat 1, the connecting seat 1 and the rotating shaft 3 are coaxially limited, thereby improving stability.

[0052] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0053] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
