Description

Technical Field

[0001] The invention relates to the technical field of machine tool material arrangement, in particular to a turning and milling compound CNC machine tool with an inclined bed and self-arranging material arrangement. Background Art

[0002] Inclined bed type turning and milling compound CNC machine tool, with its unique inclined bed structure, achieves dual improvement of rigidity and stability. At the same time, it integrates the multi-processing capabilities of turning and milling, and can complete the comprehensive processing of complex parts in one clamping, greatly improving production efficiency and processing accuracy. It is the preferred equipment in the field of modern precision manufacturing;

[0003] Metal chips are produced when the tool cuts the workpiece surface during the machining process. The shape, size and quantity of metal chips depend on the machining method, workpiece material and the type and condition of the tool. In order to reduce the cutting temperature, increase tool life and machining accuracy, cutting fluid is usually used. The cutting fluid will gradually become ineffective during use and mix with metal particles, oil and other impurities, eventually forming waste cutting fluid. This type of waste needs to be collected and treated in accordance with environmental protection requirements.

[0004] In conjunction with the above content, it should be explained that: the Chinese patent with announcement number CN221270479U discloses a slant bed turning and milling compound machine tool, which can quickly discharge debris while reducing the footprint, and can quickly process the water and remaining debris in the waste trough after the water flow flushes the waste trough. Although it is designed with a cleaning mechanism of water flow flushing and gravity discharge, for some debris with strong adhesion or large pieces, it may be difficult to completely remove them by relying solely on water flow impact. At the same time, some fine metal particles are easy to accumulate along the flow trajectory to gather, produce sedimentation and sand, and further increase the difficulty of discharge.

[0005] In view of the above technical defects, a solution is now proposed. Summary of the invention

DETAILED DESCRIPTION

[0031] 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.

[0032] Example 1: Please refer to Figure 1 - Figure 8 As shown, this embodiment is a turning and milling compound CNC machine tool with inclined bed self-discharging, comprising a discharge box 1, a vibration frame 102 is arranged on the inner wall of the discharge box 1, and an upper screen 103 and a lower screen 107 are arranged on the inner wall of the vibration frame 102;

[0033] A movable shelf 4 is arranged on the outer wall of one side of the discharge box 1, a liquid storage tank 6 is arranged at the bottom of the discharge box 1, a discharge port 101 is penetrated and opened on the other side of the discharge box 1, and a filter residue drum 5 is arranged at the bottom of the discharge port 101. When the turning and milling compound CNC machine tool processes the workpiece, the movable cover 401 is driven by the lifting cylinder to move upward along the inside of the movable shelf 4, so that the movable shelf 4 cooperates with the guide frame 104 through the movable cover 401 to seal the processing area of ​​the machine tool, so that the metal debris and cutting fluid generated by the machine tool tool head contacting the workpiece are not easy to spread to the outside, and they are concentrated and fall into the inside of the discharge box 1, and a movable cover 401 is arranged inside the movable shelf 4, and lifting cylinders connected with the movable cover 401 are embedded in the inner walls at both ends of the movable shelf 4.

[0034] Guide frames 104 are symmetrically arranged on the top of both ends of the discharge box 1, and a vibration frame 102 is embedded in the top of the inner wall of one side of the discharge box 1, and one side of the upper screen 103 and the lower screen 107 are provided with fasteners that are sleeved with the vibration frame 102, and the other sides of the upper screen 103 and the lower screen 107 are inclined toward the bottom of the discharge port 101, and a vibration motor connected to the vibration frame 102 is installed on the outer wall of one end of the discharge box 1, and the vibration motor drives the upper screen 103 and the lower screen 107 to run synchronously through the vibration frame 102, and reciprocates at a high frequency inside the discharge box 1, so that the metal debris falling on its surface is continuously vibrated and rolls to the side of the discharge port 101.

[0035] A lifting baffle 106 is arranged on the top of the discharge port 101, and an injection frame 105 located on the inner wall of the discharge box 1 is arranged on the top of the lifting baffle 106. A return plate 108 is arranged below the lower screen 107. During this period, the upper screen 103 performs preliminary screening on the metal debris, which not only causes the liquid adhering to the metal debris to be vibrated off, but also causes smaller metal debris to fall onto the lower screen 107. The lower screen 107 simultaneously vibrates the smaller metal debris in contact, which causes the liquid attached to the metal surface to be quickly separated and the smaller metal debris to be collected in the deposition chamber 503.

[0036] When the upper screen 103 and the lower screen 107 vibrate to screen the metal debris and the liquid, when the metal approaches the discharge port 101 area along the upper screen 103 and the lower screen 107, the jet rack 105 is provided with a high-pressure airflow by an external fan, and the high-pressure airflow obliquely blows toward the metal debris on the upper screen 103 and the lower screen 107, so that the liquid adhering to the surface is further cleaned.

[0037] The liquid storage tank 6 is arranged in a triangular inclined shape at the bottom of the discharge box 1, and a leakage groove connected to the reflux plate 108 is provided on the top of one side of the liquid storage tank 6, and an ultrafine filter element connected to the bottom of the filter residue drum 5 is provided on the top of the other side of the liquid storage tank 6. The ultrafine filter element is made of high-temperature molecular filtration material.

[0038] Embodiment 2: This embodiment is a turning-milling compound CNC machine tool with an inclined bed and self-discharging, including a filter residue drum 5 with a central axis 501 in the middle, and multiple arc-shaped sheets 502 arranged on the periphery of the central axis 501, and an extrusion box 2 connected to the discharge port 101 is arranged on the side of the filter residue drum 5 away from the lower screen 107, and an extrusion plate 206 and a sealing plate 205 are arranged inside the extrusion box 2.

[0039] A sedimentation chamber 503 connected to the discharge port 101 is arranged on the outer periphery of the filter residue drum 5. The bottom of the sedimentation chamber 503 filters the liquid in the smaller metal debris through the ultrafine filter element and enters the liquid storage tank 6. The excess liquid accumulates in the sedimentation chamber 503. With the continuous accumulation of smaller metal debris, the inside of the sedimentation chamber 503 is gradually filled up, causing the liquid in the sedimentation chamber 503 to overflow and leak along the lower screen 107 to the reflux plate 108, and enter the liquid storage tank 6 along the reflux plate 108.

[0040] A plurality of groups of air jet strips 504 are arranged on the inner wall of one side of the deposition chamber 503 close to the discharge port 101, a plurality of groups of capillary holes are arranged on the inner wall of the arc-shaped sheet 502, and the central axis 501 is a hollow axis. Larger metal debris enters the collecting trough 204 along the discharge port 101, and enters the bottom of the extrusion box 2 along the collecting trough 204 for accumulation. The smaller metal debris accumulated in the deposition chamber 503 is gathered in the gap between the arc-shaped sheets 502. A rotating motor connected to the central axis 501 is arranged on the outer wall at one end of the deposition chamber 503. The rotating motor drives the central axis 501 to rotate, and the central axis 501 drives the arc-shaped sheet 502 to rotate, prompting the arc-shaped sheet 502 to scrape the smaller metal debris in the deposition chamber 503. When the arc-shaped sheet 502 rotates and extends to the discharge port 101, it rolls and contacts with the larger metal debris passing through the inside of the discharge port 101, prompting some of the smaller metal debris scraped from the arc-shaped sheet 502 to fall off.

[0041] A fan is arranged on the outer wall of the discharge box 1, and the fan is connected to the jet frame 105, the jet strip 504 and the central axis 501 through a pipeline. The jet strip 504 continuously sprays gas to blow toward the passing arc piece 502, so that the metal debris scraped from the inside of the arc piece 502 is pneumatically cleaned and enters the discharge port 101, and slip rings are arranged at both ends of the axis 501 to guide the airflow into the inside of the arc piece 502. The airflow is guided to spray outward along the capillaries on the inner wall of the arc piece 502, so that the metal debris accumulated between the arc pieces 502 is quickly separated from the arc piece 502 under the multiple effects of the internal and external airflows and the external impact vibration, so as to realize the quantitative discharge of the smaller metal debris in the deposition cavity 503.

[0042] A plurality of propulsion cylinders 201 are arranged on the outer wall of the extrusion box 2 away from the discharge box 1, and a frame body embedded in the inner wall of the extrusion box 2 and connected to the propulsion cylinder 201 is arranged on the side of the extrusion plate 206. A traveling cylinder frame 203 connected to the sealing plate 205 is arranged on the same side of the propulsion cylinder 201. When various metal scraps are accumulated in the extrusion box 2, the lifting partition 106 is opened according to the processing gap on the machine tool to temporarily block the discharge port 101, and the propulsion cylinder 201 drives the extrusion plate 206 along the inside of the extrusion box 2. It moves toward the sealing plate 205, causing the metal debris accumulated inside the extrusion box 2 to be continuously squeezed, causing the metal debris to be squeezed into rectangular blocks between the extrusion plate 206 and the sealing plate 205, and the propulsion cylinder 201 drives the extrusion plate 206 to reset, and the traveling cylinder frame 203 drives the sealing plate 205 to slide until the end face outlet of the extrusion box 2 is opened, and the propulsion cylinder 201 drives the extrusion plate 206 to push the block-shaped metal debris, push it out of the extrusion box 2, and it is received by external equipment for subsequent processing.

[0043] A collecting trough 204 connected to the discharge port 101 is arranged on the top of one side of the extrusion box 2, and the interior of the collecting trough 204 is a conical structure. A plurality of groups of return liquid leaks 207 are arranged on the bottom wall of one end of the extrusion box 2 close to the sealing plate 205, and an outer conduit connected to the liquid storage tank 6 is arranged at the bottom of the return liquid leak 207. During the extrusion treatment of metal debris, part of the liquid collected in the extrusion box 2 is synchronously pushed close to the sealing plate 205, and enters the outer conduit along the plurality of groups of return liquid leaks 207 near the sealing plate 205, and enters the liquid storage tank 6 along the outer conduit. After the extrusion box 2 completes the treatment of the metal debris, the lifting partition 106 is reset.

[0044] A long rectangular groove is provided at the bottom of the machine tool connecting frame 3, a plurality of limit frames 301 are provided on the top of the machine tool connecting frame 3, and a plurality of perforations are provided on the surface of the machine tool connecting frame 3. The machine tool connecting frame 3 facilitates the fitting installation between the turning and milling compound CNC machine tool and the discharge box 1.
