Description

Technical Field

[0001] This utility model relates to the field of processing equipment technology, and in particular to a machine tool and its chip removal device and machine tool body. Background Technology

[0002] The machine tool generates chips during processing. The chips are flushed directly into the water tank through the internal water supply, and then the chip conveyor conveys them to the chip loading trolley via the chip conveyor chain.

[0003] However, since the water tank filters through a filter screen with a large aperture, fine iron filings cannot be discharged by the chip removal machine. They settle at the bottom of the water tank and accumulate over time to form layers of fine iron filings, resulting in the presence of fine iron filings in the water.

[0004] When a machine tool cuts metal, the cutting fluid drawn from the water tank contains fine iron filings. These iron filings affect the surface finish of the machined products, causing them to fail to meet standards and also damaging the water pump.

[0005] Therefore, how to better remove dander is an urgent problem to be solved. Utility Model Content

Therefore, they should not be construed as limitations on this utility model.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] To provide a clearer and more accurate understanding of the present invention, a detailed description will now be provided in conjunction with the accompanying drawings. The accompanying drawings illustrate examples of embodiments of the present invention, wherein the same reference numerals denote the same elements. It is to be understood that the scale shown in the accompanying drawings is not the actual scale of the present invention, but is for illustrative purposes only and is not a drawing based on the original dimensions.

[0032] Please refer to Figure 1 and 2 The first aspect of this utility model provides a chip removal device for a machine tool, including a discharge cylinder 100.

[0033] It is understandable that a mixture of chips and cutting fluid will flow out of the chip chute of the machine tool. In the existing technology, the chip chute generally only has one layer of filter screen, which causes small-diameter chips to flow from the filter screen into the water tank, affecting the reuse of cutting fluid.

[0034] Please refer to Figure 1The following describes how the discharge cylinder 100 achieves its discharge function. In this embodiment, in addition to forming a chip removal channel 101 within the discharge cylinder 100, the machine tool's chip removal device also includes a filter plate 110 and a chip collecting plate 120 disposed within the chip removal channel 101. It can be understood that by adding the chip collecting plate 120, this application can collect chips with smaller diameters, thereby improving the filtration capacity of the chip removal device, enabling a high degree of separation between the chips and the cutting fluid, improving the cleanliness of the cutting fluid, and allowing the cutting fluid to be reused.

[0035] Please refer to Figure 1 The following describes how the discharge cylinder 100 achieves primary filtration. The chip collection plate 120 is disposed on the bottom plate 130 of the discharge cylinder 100, and the filter plate 110 is disposed above the chip collection plate 120. The filter plate 110 is provided with filter holes 111. By providing filter holes 111 on the filter plate 110, larger diameter chips in the mixture of chips and cutting fluid can be filtered.

[0036] Please refer to Figure 1 The following describes in detail the positional relationship and connection between the bottom plate 130 and the filter plate 110 inside the discharge cylinder 100. The bottom plate 130 and the filter plate 110 of the discharge cylinder 100 are inclined downward from the inlet end R to the outlet end C of the discharge cylinder 100. At the inlet end R of the discharge cylinder 100, the bottom plate 130 and the filter plate 110 are connected, which facilitates the connection between the bottom plate 130 and the filter plate 110 and prevents the mixture of chips and cutting fluid from bypassing the filter plate 110 and flowing directly to the bottom plate 130 of the discharge cylinder 100. The bottom plate 130 of the discharge cylinder 100 has a downward tilt angle greater than that of the filter plate 110, which allows the mixture of chips and cutting fluid to undergo primary filtration through the filter plate 110 and secondary filtration through the chip collecting plate 120 on the bottom plate 130 of the discharge cylinder 100; and / or the bottom plate 130 of the discharge cylinder 100 and the chip collecting plate 120 are integrally formed, which facilitates the formation of the chip collecting groove 121, makes it easier to open the chip collecting groove 121 on the bottom plate 130 of the discharge cylinder 100, and increases the production capacity of the discharge cylinder 100.

[0037] Please refer to Figure 1 and 2 The following describes in detail how secondary filtration is achieved inside the discharge cylinder 100. A magnetic element 140 is provided on the outer side of the bottom plate 130 of the discharge cylinder 100. The bottom plate 130 and the chip collection plate 120 are magnetic plates, which allows the chip collection plate 120 to be magnetic through the bottom plate 130 and the magnetic element 140 of the discharge cylinder 100. The strength of the magnetism can be adjusted according to the actual situation. When the cross-sectional area of ​​the chips is large or the discharge volume of chips is large, the magnetism can be increased.

[0038] Please refer to Figure 1 The following describes in detail how the chip collection groove 121 on the discharge cylinder 100 is formed. The chip collection plate 120 is provided with the chip collection groove 121, which is recessed downwards relative to the chip collection plate 120 to form a chip collection space. This allows for the formation of chip collection grooves 121 of arbitrary shapes on the chip collection plate 120. In this embodiment, the cross-section of the chip collection groove 121 along its surface is rectangular, facilitating its formation. Furthermore, by adjusting the depth of the recess, the capacity of the chip collection groove 121 can be adjusted; that is, the deeper the recess, the larger the capacity of the chip collection groove 121.

[0039] Please refer to Figure 1 and 2 During the machining process of the machine tool, in order to detect the capacity of chips stored in the chip collection groove 121, the chip removal device of the machine tool also includes a detection element 200. The detection element 200 is installed on the discharge cylinder 100. The detection element 200 is used to detect the amount of chips on the chip collection plate 120. The detection element 200 is fixed relative to the filter plate 110 and the chip collection plate 120. The detection direction of the detection element 200 is located above the chip collection plate 120, so that after a preset capacity of chips is stored in the chip collection groove 121, the detection element 200 can promptly provide a reminder.

[0040] Please refer to Figure 1 and 2 The working principle of the detector 200 is described in detail below. The detector 200 includes a fixing part 210 and a detection part 220. The detection part 220 is connected to the fixing part 210 and is fixed to the discharge cylinder 100 through the fixing part 210. The detection part 220 extends into the chip discharge channel 101. The discharge cylinder 100 has a first side portion, which is connected to the bottom plate 130. The first side portion has a mounting part 150 located between the bottom plate 130 and the filter plate 110. The fixing part 210 is fixed to the mounting part 150. The detection unit 220 has a connection terminal that is electrically connected to the machine tool controller, which allows the detection unit 220 to be located in the chip removal channel 101 and to communicate with the machine tool controller, thereby facilitating the machine tool to obtain the current chip volume information; and / or the cross-sectional area of ​​the chip removal channel 101 gradually decreases along the discharge direction of the discharge cylinder 100. Through the structure of the chip removal channel 101 gradually narrowing, the flow rate of the chip and cutting fluid mixture in the chip removal channel 101 becomes faster and faster, thereby improving the chip removal capacity.

[0041] Please refer to Figure 1 and 2To facilitate the cleaning of chips collected on the chip collection plate 120, the machine tool's chip removal device also includes an air supply component 300. The air supply component 300 is installed on the mounting part 150 and is arranged side by side with the detection component 200. The air supply path of the air supply component 300 passes through the chip collection plate 120. It can be understood that the end of the air supply component 300 can have a flat outlet slit, which can increase the air supply area and air supply intensity of the air supply component 300 and improve the cleaning effect.

[0042] Please refer to Figure 1 To facilitate the collection of chips collected on the chip collection plate 120, the chip removal device of the machine tool also includes a collection cover 400. The discharge cylinder 100 has a second side portion, which is connected to the base plate 130. The second side portion is disposed opposite to the first side portion. The second side portion has a mating portion 160 facing the mounting portion 150. The mating portion 160 is provided with an opening 161. The collection cover 400 is installed on the mating portion 160 at the opening 161. The collection cover 400 is located at the lower air outlet of the air supply component 300. The chip removal channel 101 communicates with the collection cover 400 through the opening 161. By providing the opening 161, the communication between the chip removal channel 101 and the collection cover 400 can be facilitated, and the weight of the discharge cylinder 100 can be reduced.

[0043] Please refer to Figure 2 The following describes the specific location distribution of the air supply components 300. The air supply components 300 include at least two, which are arranged side by side. The air supply area of ​​the combination of the at least two air supply components 300 covers the entire chip collection trough 121. This can increase the coverage area of ​​the air supply area, achieve full coverage of the space above the chip collection trough 121, and improve the cleaning effect.

[0044] To prevent some chips from escaping from the outlet end C of the discharge cylinder 100 during the air supply process, the lower edge of the filter plate 110 has a guide portion 112 that bends toward the chip collection plate 120. The guide portion 112 is used to guide some chips toward the collection hood 400, thereby guiding some chips through the opening 161 into the collection hood 400.

[0045] The chip removal device of the above-mentioned machine tool forms a chip removal channel 101 within the discharge cylinder 100, and also includes a filter plate 110 and a chip collecting plate 120 disposed within the chip removal channel 101. The chip collecting plate 120 is disposed on the bottom plate 130 of the discharge cylinder 100, and the filter plate 110 is disposed above the chip collecting plate 120. The filter plate 110 is provided with filter holes 111. A magnetic element 140 is disposed on the outer side of the bottom plate 130 of the discharge cylinder 100. The bottom plate 130 of the discharge cylinder 100 and the chip collecting plate 120 are magnetic plates, so that the small-diameter iron chips filtered from the filter plate 110 can be magnetically attracted by the chip collecting plate 120, thereby collecting the small-diameter iron chips, improving the cleaning ability of the chip removal device, and ensuring that the cutting fluid flowing out of the chip removal device can be recycled and reused.

[0046] Please refer to Figure 3 In another aspect, this utility model also provides a machine tool body, including a base 500 and the aforementioned chip removal device for the machine tool. The chip removal device has a connecting plate 170. The base 500 is provided with a chip removal groove and a discharge port 510 communicating with the discharge groove. The chip removal device is correspondingly provided with the discharge port 510, and the connecting plate 170 is connected to the peripheral wall of the discharge port 510.

[0047] The third aspect of this utility model provides a machine tool, including a power supply circuit and a controller, and also including the aforementioned machine tool body. The power supply circuit and the controller are disposed on the machine tool body. The power supply circuit is connected to the magnetic component 140, and the controller is connected to the power supply circuit for controlling the conduction state of the power supply circuit.
