Description

Technical Field

[0001] The present application relates to the technical field of processing equipment, and in particular to a machine tool. Background Art

[0002] Graphite processing machine tools are used to process graphite. Due to the particularity of graphite materials, it is impossible to use coolant to wash graphite. Therefore, graphite has the characteristics of large dust and high dust collection requirements during processing. In addition, the long-term accumulation of graphite dust inside the machine tool will have a significant impact on the overall structure of the machine tool, especially the machine tool guide rails, and thus affect the processing performance of the machine tool. Therefore, how to more efficiently recycle graphite processing dust has become a key issue that every graphite machine tool manufacturer needs to solve urgently.

[0003] Currently common graphite processing machine tools are usually equipped with a dust suction device, which includes a dust suction body and a suction pipe. The suction pipe is usually a hose, which passes through the spindle end of the machine tool and moves together with the spindle of the machine tool. During processing, graphite dust is absorbed through the hose. Although this type of machine tool can absorb graphite dust more effectively, there is also a problem that the hose cannot change the suction direction (the hose opening can only be sucked toward the processing table), which makes the hose interfere with the workpiece when the machine tool processes the workpiece. Utility Model Content

[0034] See also Figure 1 to Figure 2 As shown, according to an embodiment of the present application, a machine tool is provided, including a main body 10 and a dust suction device.

[0035] The main body 10 is provided with a processing table 11 and a spindle box 12. The spindle box 12 is arranged on the top of the processing table 11, and the spindle box 12 can be relatively moved along the height direction of the machine tool (such as the attached Figure 1 The dust collecting device includes a suction body 21, a delivery pipe 22 and a suction pipe 23. The suction body 21 is arranged outside the main body 10. The first end of the delivery pipe 22 is connected to the suction body 21. The second end of the delivery pipe 22 is fixed to the spindle box 12. The suction pipe 23 is connected to the second end of the delivery pipe 22. The suction pipe 23 can be rotated and shaped in any direction relative to the spindle box 12.

[0036] Specifically, in this embodiment, the spindle box 12 is used to process the workpiece on the processing table 11, for example, it can be grinding the surface of the workpiece, punching or cutting the workpiece, etc. The workpiece to be processed can be, for example, a metal block, a graphite block or a silicon material. When the workpiece is processed, the dust or other impurities (such as graphite dust or graphite fragments) generated during the processing can be sucked into the dust suction device through the suction pipe 23, thereby avoiding excessive accumulation of dust or other impurities on the machine tool. In addition, the spindle box 12 of this embodiment can move relative to the processing table 11 along the height direction of the machine tool and in a plane perpendicular to the height direction of the machine tool, thereby driving the suction pipe 23 to move, so that the suction pipe 23 can be used to suck the workpiece processing. At the same time, the suction pipe 23 can be rotated and shaped in any direction relative to the spindle box 12, which means that when processing the workpiece, the suction pipe 23 can be adjusted in position and suction angle, thereby avoiding the suction pipe 23 from colliding with the workpiece, and ultimately causing damage to the suction pipe 23 or the workpiece.

[0037] Further, the suction pipe 23 includes at least one of a universal joint pipe and a bellows pipe.

[0038] Specifically, the universal joint tube and the bellows include a plurality of adjustment sections 231, and the angles between adjacent adjustment sections 231 can be adjusted, and the adjustment sections 231 can be fixed at the position after the angles are adjusted, so that the suction tube 23 can be rotated and shaped in any direction relative to the spindle box 12. In a preferred embodiment, the suction tube 23 is a universal joint tube with better shaping performance.

[0039] Further, the inner diameter D of the universal joint tube satisfies the relationship: 45 mm ≤ D ≤ 150 mm.

[0040] Specifically, in this embodiment, the inner diameter D of the universal joint tube should not be too small, that is, when D is less than 45mm, the inner diameter of the universal joint tube is small, which may cause the impurities to be stuck in the universal joint tube when sucking impurities, and ultimately reduce the suction efficiency of the universal joint tube, and fail to suck away the dust or impurities on the processing table 11 in time. When D is greater than 150mm, on the one hand, the volume of the universal joint tube is too large, which may cause interference between the universal joint tube and other components of the spindle box 12; on the other hand, the inner diameter of the universal joint tube is too large, resulting in excessively high manufacturing costs of the universal joint tube. When D satisfies the relationship 45mm≤D≤150mm, the inner diameter of the universal joint tube will not be too small, causing impurities to be stuck in the universal joint tube, and the volume of the universal joint tube will not be too large, causing excessively high manufacturing costs of the machine tool. The value of D can be 45mm, 50mm, 55mm, 60mm, 65mm, 70mm, 75mm, 80mm, 85mm, 90mm, 95mm, 100mm, 110mm, 120mm, 130mm, 140mm and 150mm.

[0041] In addition, the present embodiment includes various types of universal joint tubes, each type of universal joint tube has a different inner diameter D, and different types of universal joint tubes can be selected according to different usage scenarios. For example, when it is necessary to adsorb impurities in rough processing, a universal joint tube with a larger inner diameter can be selected to avoid large impurities from being stuck in the universal joint tube. When the workpiece is finely processed, since the impurities generated by the processing are small in volume, a universal joint tube with a smaller inner diameter can be selected to facilitate the placement of the universal joint tube, thereby avoiding interference between the universal joint tube and the workpiece.

[0042] As attached Figure 3 and attached Figure 5 As shown, a suction head 232 is provided on the suction pipe 23 , and the suction head 232 is detachably connected to an end of the suction pipe 23 away from the delivery pipeline 22 .

[0043] Specifically, a suction head 232 is installed on the suction pipe 23. Since the inner diameter of the suction head 232 is smaller than the inner diameter of the suction pipe 23, the suction head 232 can have a stronger suction force, thereby improving the suction effect of the dust suction device on dust and impurities. Of course, the suction body 21 in this embodiment can also adjust the suction force of the suction pipe 23, thereby improving the suction effect of the dust suction device.

[0044] Furthermore, the suction head 232 includes a plurality of different models, each model of the suction head 232 has a different length, and the suction heads 232 of the plurality of different models can be selectively and detachably connected to the end of the suction tube 23 away from the conveying pipe 22. When the machine tool is punching a hole in a workpiece, the longer suction head 232 can extend into the hole and adsorb dust and impurities, thereby preventing dust or impurities from affecting the processing of the workpiece. The shorter suction head 232 can be used for fine processing of the workpiece, and the suction head 232 can be attached to the workpiece to adsorb impurities of the workpiece. Of course, in some processing scenarios, the suction tube 23 may not be installed with the suction head 232, and dust and impurities can be directly adsorbed through the suction tube 23, such as during rough processing.

[0045] As attached Figure 4 and attached Figure 6 As shown, the suction head 232 has a suction port 2321 , and the shape of the suction port 2321 includes at least one of a circular shape and a long strip shape.

[0046] Specifically, the circular suction port 2321 can make the suction head 232 have better pressure resistance, that is, when the suction head 232 is sucking, the pressure generated by the gas on the inner wall of the suction head 232 is uniform, thereby improving the stability of the suction head 232. The long suction port 2321 can increase the suction area of ​​the suction head 232, and can be used when the machine tool performs rough processing on the workpiece.

[0047] As attached Figure 7 and attached Fig.10 As shown, the suction pipe 23 is further provided with an outer cover 233 , which is provided on the suction head 232 , and the projection area of ​​the outer cover 233 gradually increases along the direction in which the outer cover 233 is away from the suction pipe 23 .

[0048] In this embodiment, the outer cover 233 is used to increase the suction range of the suction head 232, so that the machine tool can absorb as much dust and impurities as possible when processing the workpiece. Figure 7 and attached Fig. 9As shown, the outer cover 233 includes a flat outer cover and an outward-expanding conical outer cover. In addition, the model of the outer cover 233 should be adapted to the model of the suction head 232. For example, a flat outer cover is usually covered on a suction head 232 with a long strip suction port 2321. The outer periphery of the suction head 232 with a circular suction port 2321 is usually covered with an outward-expanding conical outer cover.

[0049] Furthermore, the suction body 21 includes at least one of a dust collector and a vacuum pump. Specifically, the dust collector and the vacuum pump both generate negative pressure in the conveying pipe 22, so that the suction pipe 23 can adsorb dust and impurities on the processing table 11. Usually, a motor is provided in the dust collector, and an impeller is installed on the output end of the motor. The high-speed rotation of the motor drives the impeller to rotate, so that the air in the conveying pipe 22 is discharged by the impeller, so that negative pressure can be generated in the conveying pipe 22. The vacuum pump generates negative pressure in the conveying pipe 22 by discharging a certain amount of air in the conveying pipe 22 to the outside through the vacuum pump.

[0050] Furthermore, the spindle box 12 includes a box body, a driving assembly (not shown in the figure) and a spindle 121. The driving assembly is arranged in the box body. The spindle 121 is connected to the driving assembly and extends to the top of the processing table 11. The spindle 121 can rotate around its own axial direction.

[0051] Specifically, the driving component is a motor, the output end of which is connected to the spindle 121, and the spindle 121 rotates around its own axial direction under the drive of the motor. When the workpiece needs to be processed, the spindle box 12 moves, thereby driving the spindle 121 to move to a specific position, and the workpiece is processed through the components on the spindle 121. In addition, when the spindle box 12 moves, it can drive the suction pipe 23 to move, and the suction pipe 23 can absorb dust and stains generated by processing.

[0052] In a specific embodiment, the machine tool further includes a milling cutter 122, which is detachably mounted on the spindle 121. The milling cutter 122 includes a plurality of different models, and the plurality of different models of milling cutters 122 can be selectively and detachably mounted on the spindle 121. In this embodiment, the milling cutter 122 is arranged on the spindle 121, and when the spindle 121 rotates, the milling cutter 122 rotates along with the spindle 121 to process the workpiece. The different models of the milling cutters 122 have at least one of the three different shapes, outer diameters, and lengths. For example, when it is necessary to punch a hole in the workpiece, a longer small-sized conical milling cutter 122 can be selected. When it is necessary to grind the outer surface of the workpiece, a larger-sized disc-shaped milling cutter 122 can be selected to grind the surface of the workpiece.

[0053] In addition, the machine tool of the present embodiment further comprises a protective cover 30 , which is disposed on the main body 10 to prevent dust or impurities generated during the processing of the workpiece from splashing into the main body 10 of the machine tool.

[0054] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0055] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0056] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
