DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] The purpose of the present invention is to provide a self-lubricating wear-resistant plate, in which a graphite column is covered inside the self-lubricating wear-resistant plate through a limiting portion and a mounting hole, thereby avoiding the problem of the graphite column easily falling off and improving the stability of the self-lubricating wear-resistant plate during use.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] refer to Figure 1-8The self-lubricating wear-resistant plate disclosed in the embodiment of the present invention comprises: a base 1, a cover plate 2 and a graphite column 3. The base 1 is connected to the cover plate 2. A mounting hole 4 is opened on the cover plate 2. The mounting hole 4 penetrates the cover plate 2 along the thickness direction of the cover plate 2. Along the opening direction of the mounting hole 4, the size of the mounting hole 4 away from the base 1 is smaller than the size of the mounting hole 4 near the base 1. The graphite column 3 is installed in the mounting hole 4, and the shape of the graphite column 3 matches the shape of the mounting hole 4. A limiting portion is provided on the side of the base 1 close to the cover plate 2, and the limiting portion abuts against the graphite column 3. The base 1 and the cover plate 2 are connected to each other, so the base 1 can support the graphite column 3 through the limiting portion, and then the graphite column 3 is covered in the interior of the self-lubricating wear-resistant plate through the limiting portion and the mounting hole 4. Since the size of the end of the mounting hole 4 away from the base 1 is small, no matter how large the external vibration is, as long as the base 1 and the cover plate 2 are not damaged, the graphite column 3 will not fall off, which greatly improves the stability of the self-lubricating wear-resistant plate during use.

[0033] It is understandable that the limiting portion may be the base 1 itself, that is, the graphite column 3 is supported by the upper surface of the base 1 close to the cover plate 2 , or may be other structures arranged between the base 1 and the cover plate 2 .

[0034] As a preferred embodiment, the mounting hole 4 is in a frustum shape, and the radius of the mounting hole 4 gradually decreases in a direction away from the base 1 . Correspondingly, the graphite column 3 is in a frustum shape matching the mounting hole 4 .

[0035] It can be understood that: under the premise that the dimension of the end away from the base 1 is smaller than the dimension of the end close to the base 1, the mounting hole 4 can also be in the shape of a step. Of course, the shape of the mounting hole 4 can also be set to the form of multiple cones connected up and down, or multiple steps connected up and down, or a cone and a step connected up and down.

[0036] Preferably, an oil groove 5 is provided on one side of the base 1 close to the cover plate 2, and the oil groove 5 is connected to the oil supply system through an oil supply pipeline 6, and the oil groove 5 is communicated with the mounting hole 4; the lubricating oil provided by the oil supply system can enter the mounting hole 4 through the oil groove 5, and pass through the micropores inside the graphite to reach the top of the cover plate 2, thereby further improving the lubrication effect of the self-lubricating wear-resistant plate, and the excellent lubrication ability increases the load capacity of the components, and also greatly reduces working noise, reduces mechanical vibration, and thus reduces errors.

[0037] As a preferred embodiment, the oil supply pipeline 6 is connected to the flow pump; specifically, the oil supply pipeline 6 is connected to the external oil supply system, and the main component of the oil supply system is the flow pump; further, the flow pump is matched with a control component for controlling the output pressure. With the help of the function of the flow pump itself or under the regulation of the control component, the oil supply pressure in the oil circuit groove 5 can be controlled, and then the flow rate and flow rate of the lubricating oil penetrating into the upper part of the cover plate 2 can be controlled, thereby avoiding the problem of excessive oil flowing around and polluting the table surface.

[0038] Furthermore, since debris is generated during the friction between the moving parts and the cover plate 2, the present application provides a chip removal hole 7 that penetrates the cover plate 2 on the cover plate 2. The moving parts can push the generated debris into the chip removal hole 7 during the movement. At the same time, part of the lubricating oil on the surface of the cover plate 2 is also pushed into the chip removal hole 7. A chip removal plate 8 is provided between the cover plate 2 and the base 1. The chip removal plate 8 is provided with a chip removal groove, which is connected with the chip removal hole 7. The debris and lubricating oil pushed into the chip removal hole 7 flow into the chip removal groove under the action of gravity. The chip removal groove is connected to an external collection device. Finally, the debris and lubricating oil flow into the external collection device together, thereby realizing automatic cleaning of the debris, reducing friction resistance, and extending the life of the equipment.

[0039] At this time, the chip plate 8 serves as a limiting part, one side of the chip plate 8 abuts against the base 1, and the other side of the chip plate 8 abuts against the cover plate 2 and the graphite column 3, so that the chip plate 8 can provide support force for the graphite column 3.

[0040] Furthermore, the chip removal plate 8 is provided with an oil supply hole 11 which penetrates the chip removal plate 8 . The oil supply hole 11 is correspondingly arranged between the mounting hole 4 and the oil path groove 5 . The oil supply hole 11 corresponds to the mounting hole 4 and the oil path groove 5 respectively, so that the lubricating oil in the oil path groove 5 enters the oil supply hole 11 .

[0041] As a preferred embodiment, the chip removal groove includes a collecting groove 9 and a confluence groove 10. Preferably, a plurality of collecting grooves 9 are provided, and the chip removal holes 7 are arranged side by side to form a chip removal unit. The collecting groove 9 is arranged corresponding to the chip removal unit, and the confluence groove 10 is connected to multiple collecting grooves 9, and the outlet of the confluence groove 10 is connected to the inlet of an external collection device.

[0042] As a preferred embodiment, a through hole 13 penetrating the chip removal plate 8 is provided at the bottom of the confluence trough 10; further, a chip removal channel is provided on the side of the base 1 close to the chip removal plate 8, and the chip removal channel corresponds to the through hole 13 up and down and is interconnected, and the outlet of the chip removal channel is connected to the external collecting device, and the debris and lubricating oil entering the confluence trough 10 can flow downward into the chip removal channel, and finally flow to the external collecting device through the chip removal channel.

[0043] More preferably, two confluence grooves 10 are provided, and the two confluence grooves 10 are respectively provided at the two ends of the collecting groove 9, and a guiding slope inclined from the middle to the two ends is provided at the bottom of the collecting groove 9; under the action of the guiding slope, the debris and lubricating oil falling into the collecting groove 9 can flow to the confluence groove 10 autonomously, thereby improving the discharge speed of the debris.

[0044] More preferably, a cooling medium channel 12 is opened on the base 1, and the cooling medium channel 12 is connected to an external cooling medium supply device; preferably, the cooling medium is water, alcohol or air; the circulation of the cooling medium can take away the heat generated by the friction between the moving parts and the self-lubricating wear-resistant plate, which has a good cooling effect, thereby extending the service life of the equipment and enabling the self-lubricating wear-resistant plate to be used in high temperature environments.

[0045] As a preferred embodiment, the cover plate 2 is a copper plate; more preferably, the cover plate 2 and the graphite column 3 are connected by hot pressing under a high temperature and high pressure environment. Affected by thermal expansion and contraction, the mounting hole 4 and the graphite column 3 will shrink as the temperature decreases after the hot pressing. Since the expansion coefficient of copper is much larger than the expansion coefficient of the graphite column 3, the shrinkage size of the mounting hole 4 is larger than the shrinkage size of the graphite column 3. Therefore, the copper plate can be tightly wrapped around the surface of the graphite column 3, thereby improving the connection strength between the graphite column 3 and the cover plate 2, and further improving the stability of the graphite column 3 during operation.

[0046] Furthermore, the base 1 and the chip removal plate 8 can be made of carbon steel, stainless steel, cast iron, copper and the like.
