Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, and more specifically, to a bed casting assembly of a machining center. Background Art

[0002] Machine tools refer to machines that manufacture machines, also known as machine tools or machine tools, and are usually referred to as machine tools. The machinery industry usually uses gray cast iron with good wear resistance and vibration absorption to manufacture machine tool bodies. Machine tools are generally divided into metal cutting machine tools, forging machine tools, and woodworking machine tools. However, all parts with high precision requirements and fine surface roughness requirements generally need to be finally processed on machine tools by cutting methods.

[0003] When the existing bed casting assembly is in use, its surface is usually provided with multiple guide rails, which are used to install slides, gantries and other mechanisms to assist the moving parts of the machine tool to move. During the processing of the machine tool, these moving parts need to move frequently. In order to reduce the wear between them and the guide rails, lubricating oil needs to be applied to the guide rails. During the long processing process, if the guide rails are not lubricated in time, it is likely to cause abnormal wear of the guide rails, making the moving parts on the guide rails move unsmoothly, and in severe cases, it may also cause the position of the moving parts to shift, affecting the processing accuracy. For this reason, it is necessary to design a bed casting assembly with self-lubricating guide rails. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a machining center bed casting assembly to solve the problem of abnormal wear easily occurring due to untimely lubrication of the guide rails proposed in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a machining center bed casting assembly, including a bed body, a plurality of guide rails are arranged on the bed body, and a self-lubricating component is arranged on each of the guide rails; the self-lubricating component includes a groove, the groove is arranged on the upper surface of the guide rail, the upper part of the groove is rectangular, the lower part of the groove is semi-cylindrical, a plunger adapted thereto is embedded in the lower part of the groove, the plunger is cylindrical as a whole, the depth of the groove is less than or equal to the diameter of the plunger, a flow guide channel is radially penetrated on the plunger, a first oil delivery channel corresponding to the flow guide channel is arranged on the inner wall of the lower part of the groove, a second oil delivery channel connected to the first oil delivery channel is arranged in the bed body, and the second oil delivery channel is used to connect to a lubricating oil supply device.

[0006] As a preferred technical solution of the utility model, the plunger comprises a cylinder, and the outer surface of the cylinder is covered with a layer of flexible material.

[0007] As a preferred technical solution of the utility model, a cylindrical groove is coaxially opened at one end of the cylinder, an internal thread is opened in the cylindrical groove, a connecting shaft is installed in the internal thread of the cylindrical groove, and one end of the connecting shaft passes through the guide rail outward.

[0008] As a preferred technical solution of the utility model, a cavity is opened in the inner wall of the cylinder on one side of the flow guide channel, so that the masses of the cylindrical parts on both sides of the flow guide channel are unequal.

[0009] As a preferred technical solution of the utility model, the flexible material is oil-absorbing felt.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] The utility model provides a groove on the guide rail, in which a plunger is arranged. When the moving part on the guide rail moves, the friction between the plunger and the guide rail can automatically connect the flow guide channel on the plunger with the lubricating oil delivery channel, so that the lubricating oil can flow out onto the surface of the guide rail, and be smeared on various parts of the guide rail as the moving part moves. When the moving part stops moving, the flow guide channel and the oil delivery channel are staggered, and the lubricating oil does not flow out. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] like Figures 1 to 5 As shown, the utility model provides a machining center bed casting assembly, including a bed body 1, a plurality of guide rails 2 are arranged on the bed body 1, and a self-lubricating component is arranged on each guide rail 2; the self-lubricating component includes a groove 3, the groove 3 is opened on the upper surface of the guide rail 2, the upper part of the groove 3 is rectangular, the lower part of the groove 3 is semi-cylindrical, and a plunger 4 adapted thereto is embedded in the lower part of the groove 3, the plunger 4 is cylindrical as a whole, and the depth of the groove 3 is less than or equal to the diameter of the plunger 4, so that the plunger 4 can contact with the slide sliding on the guide rail 2, thereby utilizing the friction between the slide and the plunger 4 to drive the plunger 4 to rotate in the groove 3; a flow guide 5 is radially penetrated through the plunger 4, a first oil delivery channel 6 corresponding to the flow guide 5 is opened on the inner wall of the lower part of the groove 3, and a second oil delivery channel 7 connected to the first oil delivery channel 6 is opened in the bed body 1, and the second oil delivery channel 7 is used to connect the lubricating oil supply device. The oil tank of the lubricating oil supply device can be set at a height higher than the top surface of the guide rail 2. In this way, with the help of gravity and the principle of communicating vessels, the lubricating oil in the oil tank will automatically enter the first oil delivery channel 6 through the second oil delivery channel 7. After the guide channel 5 on the plunger 4 is aligned with the first oil delivery channel 6, the oil automatically flows from the first oil delivery channel 6 into the guide channel 5.

[0020] The plunger 4 comprises a cylindrical body, the outer surface of which is covered with a layer of flexible material.

[0021] A cylindrical groove 8 is coaxially formed at one end of the cylinder, and an internal thread is formed in the cylindrical groove 8. A connecting shaft 9 is installed in the internal thread of the cylindrical groove 8, and one end of the connecting shaft 9 penetrates the guide rail 2 outward. The connecting shaft 9 is mainly provided to limit the cylindrical groove 8 to prevent the cylinder from being separated from the groove 3. In order to facilitate the replacement and maintenance of the cylinder, the above method is adopted to install the cylinder. When disassembling the cylinder, it is only necessary to clamp the cylinder, twist the connecting shaft 9 to screw it out of the cylindrical groove 8, and then pull out the connecting shaft 9, and then the cylinder can be taken out of the groove 3.

[0022] A cavity 10 is provided in the inner wall of the cylinder on one side of the flow guide 5, so that the masses of the cylindrical parts on both sides of the flow guide 5 are not equal. By providing the cavity 10, the mass of the cylinder on one side of the flow guide 5 is greater than that of the cylinder on the other side. At this time, without external force driving, the part with a larger mass of the cylinder will rotate to the lower part, so that the flow guide 5 can maintain a horizontal state, so that in the initial state, the flow guide 5 on the cylinder will not be aligned with the first oil delivery channel 6, so that the plunger 4 can block the first oil delivery channel 6.

[0023] The flexible material is oil-absorbing felt, which is made of inert chemical polypropylene through a melt-blown process. It can effectively absorb liquid and retain it. In order to increase the friction between the cylinder and the slide, a flexible material is provided. The higher friction between the flexible material and the slide makes the rotation of the cylinder more convenient. At the same time, the oil-absorbing felt can also block the small gap between the cylinder and the inner wall of the groove 3, thereby preventing oil from seeping out.

[0024] The working principle and use process of this utility model:

[0025] After the slide is installed on the guide rail 2, when the slide moves along the guide rail 2, the slide floor will contact the plunger 4 in the groove 3 on the guide rail 2, so that the plunger 4 can rotate with the help of friction. During the rotation, the flow guide 5 on the plunger 4 will be aligned with the first oil delivery channel 6, so that the lubricating oil in the first oil delivery channel 6 can enter the flow guide 5 and finally flow into the upper part of the groove 3 above the plunger 4. When the oil in the upper part of the groove 3 accumulates to a certain extent, it will overflow onto the guide rail 2. When the slide moves, the overflowed lubricating oil will be smeared on the rest of the guide rail 2; when the plunger 4 does not move, the flow guide 5 and the first oil delivery channel 6 are staggered, so that the oil will not flow out when not processing.

[0026] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
