Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, and particularly relates to a numerical control boring and milling machine. Background Art

[0002] A variety of electrical components (such as motors, hydraulic components, etc.) are installed on a numerical control boring and milling machine. During the working process, the input and output lines or pipelines of the circuits and oil circuits of the electrical components are also in a follow-up state. To avoid the phenomenon of mutual pulling and entanglement of these pipelines during movement, a drag chain is provided to package and protect the relevant pipelines of the moving parts inside the drag chain. One end of the drag chain is fixed, and the other end is fixed on the moving part, which can ensure that the pipelines are neatly arranged inside the drag chain and will not interfere with each other and be entangled together.

[0003] The drag chains of traditional numerical control boring and milling machines are all arranged outside the bed body. It is necessary to cantilever install a drag chain support outside the bed body and install the drag chain inside the drag chain support. The problems are as follows: The drag chain is installed outside the bed body. On the one hand, it occupies the space outside the bed body, which has an adverse impact on the design and installation of the protective cover of the bed body. Moreover, the drag chain is not protected by a protective cover and is easily contaminated by oil and iron filings, affecting its service life. On the other hand, due to the cantilever installation of the drag chain support, after long-term operation, the drag chain support is prone to deformation, resulting in unsmooth movement of the drag chain. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a numerical control boring and milling machine, which installs the drag chain on the guide rail of the bed body, freeing up the space occupied by it on the outer wall of the bed body and facilitating the installation layout design of the overall machine protective cover; and the drag chain is installed inside the protective cover, which can effectively prevent the drag chain from being contaminated by dust, oil, iron filings, etc., and extend the service life of the drag chain.

[0005] To solve the above technical problems, the technical solution of the utility model is a numerical control boring and milling machine, including a bed body, a guide rail, and a moving saddle; a drag chain support plate is installed at the upper end of the guide rail; the cross-section of the drag chain support plate is in a "U" shape; a drag chain is installed inside the drag chain support plate; one end of the drag chain is fixedly connected to the drag chain support plate, and the other end is fixedly connected to the moving saddle.

[0006] Further, there is a gap between the two sides of the drag chain and the inner walls of the two sides of the drag chain support plate.

[0007] Further, a cushion block is fixedly connected to the upper end surface of the guide rail; the drag chain support plate is fixedly connected to the top of the cushion block.

[0008] Further, the cushion block is integrally connected to the upper end surface of the guide rail.

[0009] Advantages of the Utility Model

[0010] In this application, by installing the drag chain on the guide rail of the machine tool bed, the space occupied by it on the outer wall of the machine tool bed is freed up, facilitating the installation layout design of the overall machine protective cover. Moreover, the drag chain is installed inside the protective cover, which can effectively prevent the drag chain from being contaminated by dust, oil, iron filings, etc., and can extend the service life of the drag chain. In addition, the drag chain support plate is no longer installed cantilevered, and the support is more stable. Description of the Drawings

[0015] The following further describes the detailed embodiments of the present utility model with reference to the accompanying drawings. It should be noted here that the description of these embodiments is for helping to understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0016] A numerically controlled boring and milling machine, as Figures 1 - 3 shown, includes a machine tool bed 6, a guide rail 1, and a moving saddle 5; a drag chain support plate 2 is installed at the upper end of the guide rail 1; the cross-section of the drag chain support plate 2 is in a "U" shape; a drag chain 3 is installed inside the drag chain support plate 2; one end of the drag chain 3 is fixedly connected to the drag chain support plate 2, and the other end is fixedly connected to the moving saddle 5. Figure 1 Only a part of the drag chain 3 shown in

[0017] For the above-mentioned numerically controlled boring and milling machine, by installing the drag chain 3 on the guide rail 1 of the machine tool bed 6, the space occupied by it on the outer wall of the machine tool bed 6 is freed up, facilitating the installation layout design of the overall machine protective cover; and the drag chain 3 is installed inside the protective cover, which can effectively prevent the drag chain from being contaminated by dust, oil, iron filings, etc., and extend the service life of the drag chain 3. In addition, the drag chain support plate 2 is no longer installed cantilevered, and the support is more stable.

[0018] Specifically, there are gaps between both sides of the drag chain 3 and the inner walls of both sides of the drag chain support plate 2.

[0019] Specifically, a cushion block 4 is fixedly connected to the upper end surface of the guide rail 1; the drag chain support plate 2 is fixedly connected to the top of the cushion block 4. The bed body 6 and the guide rail 1 are castings, and the surface flatness is not high enough. The cushion block 4 can increase the distance between the bottom of the drag chain 3 and the surface of the guide rail 1. By machining the surface of the cushion block 4 to ensure the flatness of the surface of the cushion block 4, installing the drag chain support plate 2 on the flat cushion block 4 can ensure the levelness of the drag chain support plate 2, which is beneficial to the smooth movement of the drag chain 3.

[0020] Specifically, the cushion block 4 is integrally connected to the upper end surface of the guide rail 1.

[0021] The working principle of the present utility model:

[0022] In this application, by installing the drag chain 3 on the guide rail 1 of the bed body 6, the space occupied by it on the outer wall of the bed body 6 is vacated, which is convenient for the installation layout design of the whole machine protective cover; and the drag chain 3 is installed inside the protective cover, which can effectively prevent the drag chain from being polluted by dust, oil, iron filings, etc., and extend the service life of the drag chain 3. Moreover, the drag chain support plate 2 is no longer cantilever-mounted, and the support is more stable. In order to clearly show the installation position of the drag chain 3, the protective cover is not drawn in the accompanying drawings of this application specification. The protective cover is a telescopic protective cover installed on the guide rail 1 and belongs to the prior art. And only a part of the drag chain 3 drawn in this application is shown, and the end of the drag chain 3 connected to the moving saddle 5 is not drawn, but it does not affect those skilled in the art to implement this technical solution.

For those skilled in the art, without departing from the principle and spirit of the present utility model, various changes, modifications, substitutions, and variations made to these embodiments still fall within the protection scope of the present utility model.
