Abstract
Description
Technical Field
[0001] The present application relates to the technical field of numerically controlled machine tools, and in particular to a pipeline protection structure of a ram. Background Art
[0002] In a five-axis machine tool, when the five-axis head swings, the circuits, liquid circuits, gas circuits and other pipelines in the A-axis and C-axis will swing inside the slide. During the swinging process, when these pipelines come into contact with the ribs inside the slide, wear will be caused on the connections.
[0003] In order to reduce the wear on the pipelines, the ribs inside the ram are made into a circular structure in the middle, and the pipelines are wrapped with cloth tape. Since the ribs are circular in the middle and have no edges and corners, wear can be reduced. Wrapping with cloth tape can also prevent the pipelines from directly contacting the ribs, reducing friction on the pipelines. However, friction will still occur between the cloth tape and the ribs, and the cloth tape will also wear out when used for too long, and the cloth tape needs to be replaced regularly. When the cloth tape is worn, there is also a risk of damaging the pipeline. Utility Model Content
[0004] Based on this, it is necessary to provide a pipeline protection structure of a sliding pillow, and its specific technical solution is as follows.

[0006] The connecting member comprises a first connecting portion and a second connecting portion; the first connecting portion is connected to the ram, and the second connecting portion extends into the inner cavity of the ram;
[0007] A protective sleeve is placed in the inner cavity of the ram and extends along the length direction of the inner cavity of the ram, wherein the protective sleeve has a cylindrical protective cavity extending along the length direction of the inner cavity of the ram; an end of the protective sleeve is connected to the second connecting portion;
[0008] The fixed wire plate is connected to the end of the ram and is provided with a wire collecting groove, the diameter of which is smaller than the inner diameter of the protective sleeve.
[0009] Furthermore, the first connection portion is attached to and connected to the end of the ram, and the second connection portion is perpendicular to and connected to the first connection portion.

[0035] Example
[0036] Reference Figure 1-5 As shown, this embodiment provides a pipeline protection structure of a ram 100, including a connector 1, a protective sleeve 2 and a fixed line plate 3. The connector 1 includes a first connecting portion 11 and a second connecting portion 12, the first connecting portion 11 is connected to the end face of the ram 100 and fits with the end face of the ram 100, and the second connecting portion 12 is perpendicular to the first connecting portion 11 and extends into the inner cavity 101 of the ram 100. The protective sleeve 2 is placed in the inner cavity 101 of the ram 100 and extends along the length direction of the inner cavity 101 of the ram 100. The protective sleeve 2 has a cylindrical protective cavity 21 extending along the length direction of the inner cavity 101 of the ram 100, and the cylindrical protective cavity 21 is used to accommodate the pipeline passing through. The end of the protective sleeve 2 is connected to the second connecting portion 12. The fixed wire plate 3 is connected to the end plate of the ram 100 , and a wire collecting groove 31 is provided on the fixed wire plate 3 . The inner wall of the wire collecting groove 31 is arc-shaped and the diameter of the wire collecting groove 31 is smaller than the inner diameter of the protective sleeve 2 .
[0037] The pipeline protection structure of a slide 100 disclosed in this embodiment uses a connector 1 to install a protective sleeve 2 in a conventional slide 100 structure, so that the pipeline passes through a cylindrical protective cavity 21 of the protective sleeve 2. The continuous and smooth inner wall of the protective cavity can reduce the wear of the pipeline, and the wear of the pipeline can be ignored. There is no need to additionally modify the existing slide 100 structure, so the preparation is convenient and the cost is low. In addition, by fixing the wire plate 3, the pipeline is concentrated from the end position of the slide 100 to the middle position in the wire collecting groove 31, which can avoid the contact between the pipeline and the end corners of the slide 100, further reducing the risk of wear.
[0038] Specifically, the connector 1 further includes a sleeve clamping hoop 13; the outer wall of the protective sleeve 2 is fitted with the second connecting portion 12, the outer wall of the sleeve clamping hoop 13 is fitted with the inner wall of the protective sleeve 2, and the sleeve clamping hoop 13, the protective sleeve 2, and the second connecting portion 12 are connected and fixed by screws 14. The screws 14 are prevented from directly acting on the protective sleeve 2, so that the protective sleeve 2 is protected.
[0039] Specifically, the fixing wire plate 3 is connected to the side of the second connecting portion 12 away from the ram 100 and is partially fitted with the second connecting portion 12. Figure 2 As shown, the end face of the protective sleeve 2 is divided into a first area and a second area in half, and the fixed line plate 3 blocks the first area, so that the pipeline passes through the collection groove 31 and the second area. The edge of the collection groove 31 is provided with an extension portion 32, which extends into the protective sleeve 2, and an arc chamfer is formed between the extension portion 32 and the fixed line plate 3 to reduce the edges. During the operation of the machine tool, the pipeline is brought closer to the extension portion 32, and the pipeline and the slide 100 are mainly in surface contact, thereby reducing the wear on the pipeline.
[0040] Specifically, refer to Figure 4 As shown, an annular rib plate 102 is provided in the inner cavity 101 of the slide 100, and the protective sleeve passes through each rib plate 102 and forms a gap between the rib plates 102, which is convenient for installing the protective sleeve on the one hand and avoids wear caused by contact between the protective sleeve and the rib plates 102 on the other hand.
[0041] In this embodiment, the protective sleeve 2 can be made of PE material.
[0042] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.
[0043] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
