Among them, the z -axis drives the tool bit, which is directly aligned with the workpiece to be machined, so the lubricating oil will drip onto the workpiece or the operation platform with the tool bit. In the cutting process, the continuously sprayed cutting fluid also drips, which causes the cutting fluid to be contaminated after mixing with the oil, reducing the service life of the cutting fluid.

[0033] The specific implementation of the present application will be described below in conjunction with the drawings.

[0034] As Figures 1-9 shown, the machining center multi-axis lubricating oil oil-water separation collection structure of the embodiment is applicable to a machining machine tool with at least one z-axis sliding structure, comprising a z-axis collection assembly 1, a collection channel in communication with the z-axis collection assembly 1, the collection channel being communicated to an oil tank outside the machining center,

[0035] The z-axis collection assembly 1 comprises:

[0036] A scraper 101 abuts against the z-axis of the machining center,

[0037] An oil guide plate 102 is received below the z-axis and communicated to the collection channel.

[0038] The scraper 101 is received at the bottom end of the z-axis and abuts against the sidewall of the bottom end of the z-axis.

[0039] The scraper 101 is a semi-cladding structure or a cladding structure and is arranged around the sidewall of the z-axis.

[0040] The oil guide plate 102 is arranged obliquely to form a guide oil flow direction.

[0041] The collection channel comprises a y-direction oil channel 2 installed at the y-axis.

[0042] The y-direction oil channel 2 receives the oil outlet end of the oil guide plate 102, and the y-direction oil channel 2 is connected with an external oil tank.

[0043] The collection channel comprises an oil channel installed at the y-axis and an oil channel installed at the x-axis.

[0044] The y-direction oil channel 2 directly receives the oil outlet end of the oil guide plate 102, the y-direction oil channel 2 is provided with an oil outlet pipe 4, the oil outlet of the oil outlet pipe 4 is always located above the x-direction oil channel 3, and the x-direction oil channel 3 is connected with an external oil tank.

[0045] The oil outlet pipe 4 is attached and installed on the y-direction sliding structure and reciprocates with the y-direction sliding structure; the oil outlet of the oil outlet pipe 4 reciprocates above the x-direction oil channel 3.

[0046] The specific structure and working principle of this utility model are as follows:

[0047] like Figures 1-3 As shown, this utility model can theoretically be used for collecting lubricating oil in machining centers with at least one set of z-axis structures. As long as an oil passage is added after the z-axis collection component 1 and connected to an external oil tank through the oil passage, the collection of lubricating oil on multiple axes can be achieved.

[0048] like Figures 4-6 As shown, the structure used to collect lubricating oil on the z-axis is the z-axis collection assembly 1. The z-axis collection assembly 1 includes a scraper 101 located in the horizontal plane and partially covering the z-axis. An oil guide plate 102 is provided on the side of the scraper 101 away from the z-axis. The oil guide plate 102 has a certain slope to facilitate the flow and output of oil in the subsequent direction.

[0049] As an optimized implementation plan, such as Figure 6 As shown, the scraper 101 and the oil guide plate 102 are relatively short in the vertical direction, and may not be able to support the subsequent oil passage. Therefore, this embodiment also provides a structure with a compensation section 104. The compensation section 104 is a vertical plate connected to the side of the scraper 101 away from the z-axis. The oil guide plate 102 is connected to the bottom of the compensation section 104. In this way, the compensation section 104 can make up for the height difference between the bottom of the z-axis and the subsequent y-axis oil passage 2.

[0050] like Figure 5 As shown, the z-axis, which is partially covered by the scraper 101, is essentially an irregularly shaped rod that needs to reciprocate vertically in the z-axis motion structure. In order to cooperate with the z-axis, the scraper 101 is designed as a plate surrounding the z-axis in three directions, which can scrape off excess oil as much as possible.

[0051] In use, the oil outlet is located above the moving part. The oil output from the outlet drips along the Z-axis. Combined with the movement of the Z-axis, excess oil is guided into the oil guide plate 102 by the scraper 101 and flows to the subsequent oil passage. The advantage of this structure is that the oil will not mix with the previously sprayed cutting fluid and fall onto the machining center table.

[0052] In addition, in order to improve the connection strength of scraper 101, such as Figure 8 and Figure 9 As shown, a clamping plate 103 is fixedly formed on the top of the compensation section 104. The clamping plate 103 has a two-piece structure, which clamps the scraper 101 in the middle and is fastened with screws or other fasteners. The size of the clamping plate 103 is slightly smaller than that of the scraper 101. The middle of the clamping plate 103 is concave to expose the special clamping shape of the scraper 101, which cooperates with the z-axis.

[0053] In this embodiment, the cross-sectional shape of the z-axis tends to be butterfly-shaped, so the concave shape of the scraper 101 is also designed to be a matching butterfly shape, thus adapting to the installation.

[0054] The following explanations will focus on two working conditions: z-axis and y-axis, and z-axis, y-axis, and x-axis.

[0055] Example 1

[0056] A machining center has a Z-axis and a Y-axis for machining a product in the Y-axis direction. Oil flows down the Z-axis; as the Z-axis moves downwards, a scraper 101 moves upwards relative to the Z-axis to remove excess oil. The oil flows along the compensation section 104 and the guide plate 102 into the Y-axis oil passage 2. The Y-axis oil passage 2 is located on the side wall of the Y-axis facing the Z-axis. It can be positioned at the junction of the side wall and bottom wall of the Y-axis to avoid affecting the movement of other components. The Y-axis oil passage 2 is connected to an external oil tank via an oil outlet pipe 4 for oil collection.

[0057] Example 2

[0058] A machining center has a z-axis, a y-axis, and an x-axis for machining a surface of a product. Oil flows down the z-axis; as the z-axis moves downward, a scraper 101 moves upward relative to the z-axis to scrape off excess oil. The oil flows along the compensation section 104 and the guide plate 102 into the y-axis oil passage 2.

[0059] An oil outlet pipe 4 extends from the Y-axis oil passage 2. The oil outlet pipe 4 is a flexible pipe, such as a rubber hose or corrugated pipe. Since the Y-axis motion mechanism often uses a common gantry frame, the oil outlet pipe 4 extends from one end of the Y-axis oil passage 2. The main body of the oil outlet pipe 4 is attached to the side wall of the gantry frame and reciprocates along the X-axis with the gantry frame. During the X-axis reciprocating motion, the oil outlet of the oil outlet pipe 4 is always located above the X-axis oil passage 3. The X-axis oil passage 3 is located above the X-axis on both sides of the machining center's worktable. At least one side has an X-axis oil passage 3, or both sides can be equipped with X-axis oil passages to prevent excessive oil overflow from a single oil passage. The X-axis oil passage 3 is connected to an external oil tank via the oil outlet pipe 4 to collect the oil.

[0060] The advantage of this invention is that it can actively collect excess oil. A Z-axis collecting component 1 is set at the bottom of the Z-axis, which can generate an active oil scraping action as the Z-axis reciprocates. Compared with conventional collection, which only uses the method of receiving oil at the bottom and waiting for the oil to drip down, this invention cleans more promptly. At the same time, it can use the scraping action to spread the oil evenly on the Z-axis, improving the degree of lubrication.

[0061] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
