Description

Technical Field

[0001] The present invention relates to the technical field of numerically controlled lathe manipulators, and more particularly, to a chip collection manipulator that moves synchronously with a turning tool. Background Art

[0002] When a lathe controls a turning tool to cut a workpiece, the turning tool cuts the surface of the workpiece, causing the cut part of the workpiece to form chips. The chips cut by the turning tool will be inside the lathe. After the lathe has been used for a period of time, the chips cut by the turning tool will accumulate inside the lathe. At this time, in order to ensure the cleanliness inside the lathe, it is necessary to clean and collect the chips inside the lathe. During the process of cleaning and collecting the chips, the lathe needs to be shut down. At the same time, the chips gather inside the lathe and are likely to fall onto the mechanical components inside the lathe, such as gears, screws, and nuts. When the gears, screws, and nuts are working, the chips will be crushed by the gears, screws, and nuts. During the process of the gears, screws, and nuts squeezing the chips, their own wear will be accelerated, thereby reducing the accuracy of the components. As the machining accuracy of numerically controlled lathes continues to increase, the loss of components will reduce the machining accuracy of numerically controlled lathes, thereby affecting the normal use of numerically controlled lathes. Therefore, a device that can collect chips is needed to improve the wear condition of numerically controlled lathes, thereby increasing the service life of numerically controlled lathes. Summary of the Invention

[0003] In view of the above technical problem that the chips generated by the turning tool cutting the workpiece are likely to cause wear of the internal components of the lathe and reduce the machining accuracy of the lathe, a chip collection manipulator that moves synchronously with the turning tool is provided.

[0004] The technical means adopted by the present invention are as follows:

[0005] A chip collection manipulator that moves synchronously with a turning tool, which is installed on the side of the tool mounting table of a numerically controlled lathe, and includes a collection member, a pulling component, and a displacement component; the collection member includes a collection mechanism and an air pump; the collection mechanism includes a loading component and a deformation component; one side of the deformation component is connected to the loading component, and the other side is installed with the displacement component; the displacement component is installed on the tool mounting table and is used to adjust the distance between the collection member and the workpiece installed on the chuck of the numerically controlled lathe; the deformation component supports the loading component, and two pulling components are symmetrically arranged up and down on one side of the loading component. The pulling component is connected to the deformation component, and the deformation component can drive the loading component to change its shape together under the action of the pulling component, so that the loading component can fit the workpiece; the air pump is connected to the loading component through a pipeline, and chips generated when the turning tool on the tool mounting table cuts the workpiece are collected by forming a negative pressure inside the loading component.

[0006] Further, the deformation component includes a connecting rod, one end of the connecting rod is fixed with an arc end plate, and a plurality of arc turning plates are sequentially hinged on the upper and lower sides of the connecting rod. The arc turning plate far from the arc end plate is hinged with an arc pulling plate, and one end of the arc pulling plate extends towards the direction close to the connecting rod.

[0007] Further, arc elastic plates are symmetrically fixed on the upper and lower sides of the other end of the connecting rod. A plurality of openings are formed in the arc elastic plates. The arc elastic plates, the arc end plate, the arc turning plates and the arc pulling plates are combined to form a collection shell for collecting debris.

[0008] Further, the loading component includes a flexible outer sheath sleeved outside the collection shell; torsion springs are installed at the hinged positions between the arc end plate and the arc turning plates and between the arc turning plates and the arc pulling plates. The torsion springs drive the arc turning plates and the arc pulling plates to elastically deform in the direction away from the arc elastic plate, and the arc elastic plate elastically deforms in the direction away from the arc end plate. The elastic force of the arc elastic plate is less than the elastic force of the torsion spring.

[0009] Further, two mounting rods are fixed on the side of the arc elastic plate far from the arc end plate. A driving plate is fixed at the ends of the two mounting rods far from the arc elastic plate. The pulling component is installed on the mounting rods, and the pulling component is connected to the pulling plate on the arc pulling plate to pull the pulling plate towards the direction close to the arc elastic plate. The pulled arc pulling plate drives the arc turning plate to rotate towards the direction close to the arc elastic plate, and the arc elastic plate is extruded during the movement of the arc pulling plate, so that the arc elastic plate elastically deforms towards the direction close to the mounting rods.

[0010] Further, a pulling plate penetrating through the flexible outer sheath is fixed on the arc pulling plate. Threading plates penetrating through the flexible outer sheath are fixed at the upper end and the middle position of the arc elastic plate. The pulling component includes a thin fiber wire with one end tied to the pulling plate, and the other end of the thin fiber wire slides through the two threading plates.

[0011] Further, limit members are arranged at the hinged positions between the arc end plate and the arc turning plates and between the arc turning plates and the arc pulling plates. The limit members include two inner blocking plates and an outer blocking plate arranged between the two inner blocking plates; the outer blocking plate is located on the side close to the arc elastic plate and is used to block the arc turning plates and the arc pulling plates from rotating towards the direction close to the arc elastic plate; the inner blocking plates are located on the side far from the arc elastic plate and are used to block the arc turning plates and the arc pulling plates from rotating towards the direction away from the arc elastic plate.

[0012] Furthermore, the pulling assembly also includes two base plates respectively fixed on two mounting rods, a winding roller is rotatably installed between the two base plates, one end of the fine filament is wound around the winding roller, and a first motor for rotating the winding roller is installed on the base plate.

[0013] Furthermore, the displacement assembly includes a sliding frame slidably arranged between two mounting rods, a threaded rod is rotatably arranged inside the sliding frame, the driving plate is slidably arranged on the sliding frame, the threaded rod is threadedly connected to the driving plate, the driving plate is fixed to the mounting rod by screws, an end plate fixed to the sliding frame is arranged on one side of the driving plate, a side slide plate is slidably arranged on the outer side of the mounting rod, one end of the side slide plate is connected to the end plate by screws, a connecting frame is fixed on the two side slides, the connecting frame is fixed to the tool mounting table by screws, and a second motor that drives the threaded rod to rotate is installed on the connecting frame.

[0014] Furthermore, a guide groove is provided on the end surface of the arc-shaped pull plate close to the arc-shaped elastic plate, and an inclined bevel head is fixed on the end surface of the arc-shaped elastic plate close to the arc-shaped pull plate. When the arc-shaped pull plate is close to the arc-shaped elastic plate, the end of the bevel head slides into the guide groove.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. The chip collection robot provided by the present invention moves synchronously with the turning tool, adjusts the distance between the collection piece and the workpiece through the displacement component, so that the receiving component can be close to the workpiece, and at the same time, the end of the deformation component is pulled by the pulling component, so that the shape of the deformation component can be adjusted according to the size of the workpiece, thereby ensuring that the collection piece can adapt to workpieces of different sizes. When the turning tool cuts the workpiece, the pulling component changes the shape of the collection mechanism so that the collection mechanism can receive the debris cut by the turning tool, thereby preventing the debris from falling into the interior of the CNC lathe. At the same time, the negative pressure formed by absorbing the gas in the receiving component with the help of the air pump can make the fine debris cut by the turning tool also be captured by the receiving component, thereby preventing the fine debris from falling onto the parts in the CNC lathe and increasing the wear of the parts.

[0017] 2. During the process of the pulling component pulling the arc-shaped pull plate, the debris collection manipulator that moves synchronously with the turning tool causes the arc-shaped pull plate to drive several arc-shaped turning plates to rotate towards the direction close to the arc-shaped elastic plate, thereby changing the shape of the side of the deformation component close to the workpiece. In this way, when the turning tool performs machining of different shapes on the workpiece, the distance between the deformation component and the workpiece can be effectively adjusted to ensure that all the cut debris can be received by the deformation component. At the same time, during the movement of the arc-shaped pull plate, the arc-shaped pull plate pushes the arc-shaped elastic plate, causing the arc-shaped elastic plate to deform, thereby ensuring the size of the space inside the deformation component and guaranteeing the ability of the deformation component to collect debris.

[0042] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments may be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0043] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part rather than all of the embodiments of the present invention. The description of at least one exemplary embodiment below is actually only illustrative and in no way limits the present invention and its application or use. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0044] It should be noted that the terms used herein are only for describing the specific implementation manners and are not intended to limit the exemplary embodiments according to the present invention. As used herein, unless otherwise clearly specified in the context, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of the described features, steps, operations, devices, components and / or their combinations.

[0045] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the specification. In all the examples shown and discussed here, any specific values should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0046] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal", and "top, bottom" are generally based on the orientation or positional relationships shown in the drawings. These are only for the convenience of describing the present invention and simplifying the description. Without contrary statements, these orientation words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of the present invention: The orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0047] For ease of description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "above" can be used here to describe the spatial positional relationship between a device or feature shown in the drawing and other devices or features. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation described in the drawing of the device. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above" can include both the orientation of "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0048] In addition, it should be noted that the use of words such as "first", "second" to limit components is only for the convenience of differentiating the corresponding components. Without additional statements, the above words have no special meanings. Therefore, they should not be construed as limiting the scope of protection of the present invention.

[0049] Embodiment 1

[0050] As shown Figure 1 in Figure 1, a tool mounting table 11 is provided inside the numerically controlled lathe 1. The turning tool is mounted on the tool mounting table 11. The numerically controlled lathe 1 clamps the workpiece through a chuck. After the workpiece is fixed by the chuck, it will drive the workpiece to rotate. The numerically controlled lathe 1 will drive the turning tool to cut the workpiece by driving the tool mounting table 11. When the workpiece is being cut by the turning tool, the cut chips will fly on the lathe. When the chips fall onto the components in the lathe, the working components will drive the chips to move, causing the components to squeeze and crush the chips. The crushed chips will reduce the accuracy of the components. For example, when the gear crushes the chips, it will experience its own wear, making the meshing between the gears not tight. As a result, when the gear drives another gear to rotate, it cannot drive the other gear to rotate in time, thus affecting the machining precision of the numerically controlled lathe 1.

[0051] Therefore, the present invention provides a Figures 1 to 20 chip collection manipulator that moves synchronously with the turning tool as shown in Figure 2. The manipulator is installed on the side of the tool mounting table 11 on the numerically controlled lathe 1. The manipulator includes a collection member, a pulling component 3, and a displacement component 4. As shown Figure 1 in Figure 3, the manipulator is arranged on the side of the tool mounting table 11 close to the chuck, that is, between the tool mounting table 11 and the chuck. When the turning tool cuts the workpiece, the cut chips will move according to the installation position of the cutting edge of the turning tool. Usually, the chips cut by the turning tool will move towards the direction of the chuck on the left (i.e., the chip flow direction is towards the surface to be machined). Of course, the manipulator can also be installed on the other side of the tool mounting table 11 according to the installation requirements. The collection member can collect the chips cut by the turning tool to prevent the chips from flying inside the numerically controlled lathe 1.

[0052] As shown Figures 2 to 5As shown, the collecting member includes a collecting mechanism 2 and an air pump; the collecting mechanism 2 includes a loading component 21 and a deformation component 22; one side of the deformation component 22 is connected to the loading component 21, and the displacement component 4 is installed on the other side; the displacement component 4 is installed on the tool mounting table 11 for adjusting the distance between the collecting member and the workpiece installed on the chuck of the CNC lathe 1; the deformation component 22 supports the loading component 21, and two pulling components 3 are symmetrically arranged up and down on one side of the loading component 21. The pulling component 3 is connected to the deformation component 22. The deformation component 22 can drive the loading component 21 to change its shape under the action of the pulling component 3, so that the loading component 21 can fit the workpiece; the deformation component 22 makes the loading component 21 form an arc shape. During use, the loading component 21 is arranged close to the workpiece. The air pump is connected to the loading component 21 through a pipeline. The air pump is a common air pump. The air pump is installed inside the lathe, and the pipeline is arranged at the position where the lathe processes the workpiece. The air pump collects the chips generated when the turning tool on the tool mounting table 11 cuts the workpiece by forming a negative pressure inside the loading component 21.

[0053] The air pump can absorb the gas inside the loading component 21. When the air pump absorbs the gas inside the loading component 21, it enables the loading component 21 to capture the air near the turning tool. When the turning tool cuts the workpiece, due to the inertia generated during cutting and the influence of the air flow, both large and small chips will enter the loading component 21.

[0054] At the same time, the two pulling components 3 respectively adjust the upper and lower ends of the deformation component 22, change the shape of the side of the deformation component 22 close to the workpiece, so that the deformation component 22 drives the loading component 21 to be close to the workpiece, thereby ensuring the effective collection of chips by the collecting mechanism 2.

[0055] The pulling component 3 and the displacement component 4 jointly adjust the shape and position of the collecting mechanism 2, so that the loading component 21 can fit the workpiece, and the loading component 21 collects the chips cut by the turning tool. In this way, it is avoided that the chips fall into the inside of the CNC lathe 1 and affect the normal use of the CNC lathe 1. At the same time, the loading component 21 collects the chips cut by the turning tool, so that the chips will not accumulate inside the CNC lathe 1, eliminating the trouble for workers to stop the CNC lathe 1 later to clean the chips.

[0056] Further, as Figures 6 to 9As shown, the deformation component 22 includes a connecting rod 221. One end of the connecting rod 221 is fixed with an arc-shaped end plate 222. The turning tool and the arc-shaped end plate 222 are at the same height, that is, the turning tool is at the middle position of the vertical height of the deformation component 22. When the turning tool cuts chips, the loading component 21 and the deformation component 22 can better collect the chips. The arc-shaped end plate 222 is arc-shaped, and its center of the circle is far from the connecting rod 221. A number of arc-shaped turning plates 224 are successively hinged on the upper and lower sides of the connecting rod 221. The arc-shaped turning plates 224 are arc-shaped, and the arc-shaped turning plates 224 and the arc-shaped end plate 222 have the same arc radius. The arc-shaped turning plate 224 far from the arc-shaped end plate 222 is hinged with an arc-shaped pulling plate 225. One end of the arc-shaped pulling plate 225 extends towards the direction close to the connecting rod 221. The part of the arc-shaped pulling plate 225 extending towards the connecting rod 221 is also arc-shaped, and its center of the circle is on the side of the arc-shaped end plate 222 close to the connecting rod 221.

[0057] Further, arc-shaped elastic plates 223 are symmetrically fixed to the upper and lower sides of the other end of the connecting rod 221. The connecting rod 221 is arranged on the side positions of the arc-shaped end plate 222 and the arc-shaped elastic plates 223. The arc-shaped elastic plates 223, the arc-shaped end plate 222, the arc-shaped turning plates 224 and the arc-shaped pulling plates 225 are combined to form a collection shell for collecting chips. The collection shell is used to collect chips. At the same time, the arc-shaped elastic plates 223 are arc-shaped, and their centers of the circle are on the sides of the arc-shaped elastic plates 223 close to the arc-shaped end plate 222. The arc-shaped elastic plates 223 are made of the material quality of spring sheets and have elasticity themselves. Torsion springs are installed at the hinged positions between the arc-shaped end plate 222 and the arc-shaped turning plates 224 and between the arc-shaped turning plates 224 and the arc-shaped pulling plates 225. The torsion springs drive the arc-shaped turning plates 224 and the arc-shaped pulling plates 225 to elastically deform in the direction away from the arc-shaped elastic plates 223, and the arc-shaped elastic plates 223 elastically deform in the direction away from the arc-shaped end plate 222. The elastic force of the arc-shaped elastic plates 223 is less than the elastic force of the torsion springs. At the same time, in order to ensure that the torsion springs are greater than the elastic force of the arc-shaped elastic plates 223, a number of openings are provided on the arc-shaped elastic plates 223 to reduce the self-elastic force of the arc-shaped elastic plates 223 through the openings.

[0058] Further, as Figure 11As shown, limit members are provided at the hinged positions between the arc end plate 222 and the arc flip plate 224, and between the arc flip plate 224 and the arc pull plate 225. The limit member includes two inner blocking plates 2291 and an outer blocking plate 229 disposed between the two inner blocking plates 2291. The outer blocking plate 229 is located on the side close to the arc elastic plate 223 and is used to block the arc flip plate 224 and the arc pull plate 225 from rotating in the direction close to the arc elastic plate 223. The inner blocking plate 2291 is located on the side far from the arc elastic plate 223 and is used to block the arc flip plate 224 and the arc pull plate 225 from rotating in the direction away from the arc elastic plate 223. By blocking the arc flip plate 224 and the arc pull plate 225 with the outer blocking plate 229 and the inner blocking plate 2291, the rotation angles of the arc flip plate 224 and the arc pull plate 225 can be limited, avoiding the situation where several arc flip plates 224 are wound together due to excessive rotation angles between the arc flip plate 224 and the arc pull plate 225.

[0059] Further, between the arc end plate 222 and the arc flip plate 224, the inner blocking plate 2291 is disposed on the arc end plate 222, and the outer blocking plate 229 is disposed on the arc flip plate 224. Between the arc flip plate 224 and the arc pull plate 225, the inner blocking plate 2291 is disposed on the arc flip plate 224, and the outer blocking plate 229 is disposed on the arc pull plate 225.

[0060] Further, the loading assembly 21 includes a flexible outer sheath sleeved outside the collection shell. The flexible outer sheath is made of Teflon high-temperature resistant fabric, which is heat-resistant and will not be damaged by the temperature carried by the debris. At the same time, its surface is smooth and debris is not easily adhered to the fabric. The deformation assembly 22 can support the flexible outer sheath, so that the flexible outer sheath forms as Figure 6The shape shown; the flexible outer sheath is formed by connecting an outer protective surface 211, an inner protective surface 213, and end protective surfaces 212 that connect the outer protective surface 211 and the inner protective surface 213. At the same time, one side of the outer protective surface 211, the end protective surface 212, and the inner protective surface 213 is blocked with Teflon high-temperature resistant fabric; the inner protective surface 213 fits against the outer side walls of the arc-shaped end plate 222 and the arc-shaped turning plate 224, the outer protective surface 211 fits against the outer side walls of the arc-shaped elastic plate 223, and the end protective surface 212 respectively fits against the ends of the arc-shaped pull plate 225 and the arc-shaped elastic plate 223. Moreover, the ends of the arc-shaped pull plate 225 and the arc-shaped elastic plate 223 are fixedly connected to the end protective surface 212 by screws, so as to fixedly connect the flexible outer sheath and the deformation assembly 22; at the same time, a sandwich layer 214 is fixed on one side of the inner protective surface 213 close to the outer protective surface 211, and the sandwich layer 214 contacts the inner side surfaces of the arc-shaped end plate 222 and the arc-shaped turning plate 224; at the same time, an installation opening 216 is formed in the Teflon high-temperature resistant fabric on one side of the outer protective surface 211 and the inner protective surface 213, the connecting rod 221 is arranged in the installation opening 216, and the edge of the installation opening 216 in contact with the connecting rod 221 is sealed with silicone; a connecting pipe 215 is connected to the Teflon high-temperature resistant fabric below the installation opening 216, the connecting pipe 215 is connected to the pipeline, and the air pump captures the air inside the loading assembly 21 through the pipeline and the connecting pipe 215.

[0061] Further, as Figures 12 to 14As shown, two mounting rods 226 are fixed to the side of the arc-shaped elastic plate 223 away from the arc-shaped end plate 222. At the ends of the two mounting rods 226 away from the arc-shaped elastic plate 223, a driving plate 2261 is fixed. The displacement assembly 4 includes a sliding frame 41 slidably disposed between the two mounting rods 226. A threaded rod 42 is rotatably disposed inside the sliding frame 41. The driving plate 2261 is slidably disposed on the sliding frame 41. The threaded rod 42 is threadedly connected to the driving plate 2261. The driving plate 2261 is fixed to the mounting rod 226 by screws. On one side of the driving plate 2261, there is an end plate 43 fixed to the sliding frame 41. A side sliding plate 44 is slidably disposed on the outer side of the mounting rod 226. One end of the side sliding plate 44 and the end plate 43 are connected by screws. By restricting the position of the sliding frame 41 by the two side sliding plates 44, the sliding frame 41 can stably slide between the two mounting rods 226. When the threaded rod 42 rotates, due to the threaded connection between the threaded rod 42 and the driving plate 2261, the driving plate 2261 drives the mounting rod 226 to slide on both sides of the sliding frame 41. Two connecting frames 45 are fixed to the two side sliding plates 44. A second motor 46 for driving the threaded rod 42 to rotate is installed on the connecting frame 45. The connecting frame 45 is of H shape. The two side sliding plates 44 are respectively fixed to two of the ends of the connecting frame 45. The connecting frame 45 is fixed to the tool mounting table 11 by screws, so as to fix the collecting mechanism to the side of the tool mounting table 11, enabling the collecting mechanism to move together with the movement of the turning tool, thereby facilitating the receiving assembly 21 to collect the chips cut by the turning tool.

[0062] Further, when the rotating shaft of the second motor 46 rotates, it drives the threaded rod 42 to rotate. During the rotation of the threaded rod 42, due to the threaded connection with the driving plate 2261, the driving plate 2261 can slide on the sliding frame 41. During the movement of the driving plate 2261, it drives the entire collecting mechanism 2 to move. When the turning tool follows the machining instructions of the CNC lathe, the numerical control instructions can also control the operation of the second motor 46, enabling the displacement assembly 4 to drive the collecting mechanism 2 to move closer to or away from the workpiece according to the instructions.

[0063] Further, if the feed path of the turning tool is to move straight forward and then move in the direction closer to the axis of the workpiece, at this time, the movement trajectory of the collecting mechanism 2 can be adjusted according to the distance between the turning tool and the collecting mechanism 2, so that the collecting mechanism 2 moves following the instruction, thus ensuring that the collecting mechanism 2 can be close to the workpiece and ensuring that the chips cut by the turning tool can be collected by the collecting mechanism 2; in order to prevent friction between the arc-shaped end plate 222 and the workpiece, a fitting roller 2221 is rotatably provided on the side of the arc-shaped end plate 222 away from the arc-shaped elastic plate 223, and the central axis of the fitting roller 2221 is parallel to that of the arc-shaped end plate 222; since the workpiece rotates along the axis of the workpiece during cutting, when the arc-shaped end plate 222 approaches the workpiece, the fitting roller 2221 will contact the surface of the workpiece, and through the rolling friction between the fitting roller 2221 and the workpiece, it is ensured that there is no contact between the workpiece and the arc-shaped end plate 222, thereby preventing the inner protective surface 213 from being worn by the workpiece.

[0064] Further, as Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 15 and Figure 17 shown, a pull plate 227 that penetrates the flexible outer sheath is fixed on the arc-shaped pull plate 225, that is, the pull plate 227 penetrates the end protective surface 212; threading plates 228 that penetrate the flexible outer sheath are fixed at the upper end and the middle of the arc-shaped elastic plate 223, that is, the two threading plates 228 penetrate the end protective surface 212 and the outer protective surface 211 respectively;

[0065] The pulling component 3 is installed on the mounting rod 226. The pulling component 3 is connected to the pulling plate 227, and pulls the pulling plate 227 in the direction close to the arc-shaped elastic plate 223. The pulled arc-shaped pulling plate 225 drives the arc-shaped turning plate 224 to rotate in the direction close to the arc-shaped elastic plate 223. During the movement of the arc-shaped pulling plate 225, the arc-shaped elastic plate 223 is squeezed, causing the arc-shaped elastic plate 223 to elastically deform in the direction close to the mounting rod 226. By pulling the arc-shaped pulling plate 225 through the pulling component 3, the arc-shaped pulling plate 225 is deformed to approach or move away from the arc-shaped elastic plate 223, changing the shape of the collection mechanism 2. At this time, the side wall of the inner protective surface 213 moves closer to or away from the workpiece, enabling the inner protective surface 213 to be close to the workpiece, so that the collection mechanism 2 can adapt to workpieces of different sizes. At the same time, according to the cutting amount of the turning tool, the distance between the inner protective surface 213 and the workpiece is adjusted. That is, when the cutting amount of the turning tool is large, the cut debris particles are larger, and at this time the debris will fly away from the workpiece. At this time, by adjusting the distance between the inner protective surface 213 and the workpiece, the receiving component 21 receives the flying debris. When the cutting amount of the turning tool is small, the particles of the cut debris are small, and the flying direction of the debris is irregular. At this time, by bringing the inner protective surface 213 close to the workpiece, the receiving component 21 can effectively receive the small particle debris. At the same time, by means of the negative pressure generated when the air pump absorbs the gas of the receiving component 21, the small particle debris can better enter the receiving component 21, thereby achieving the collection of the debris cut by the turning tool.

[0066] Further, the structure of the pulling component 3 is refined as follows. The pulling component 3 includes a thin fiber 35 with one end tied to the pulling plate 227, and the other end of the thin fiber 35 slidably passes through the two wire threading plates 228. The pulling component 3 further includes two bottom plates 31 respectively fixed on the two mounting rods 226. A wire winding roller 32 is rotatably installed between the two bottom plates 31. One end of the thin fiber 35 is wound around the wire winding roller 32. A first motor 36 for rotating the wire winding roller 32 is installed on the bottom plate 31. When the first motor 36 drives the wire winding roller 32 to rotate, the wire winding roller 32 can wind or unwind the thin fiber 35. At the same time, a mounting bracket 33 is fixed on the bottom plate 31, and a wire guiding wheel 34 is installed on the mounting bracket 33. The wire guiding wheel 34 is arranged between the wire winding roller 32 and the arc-shaped elastic plate 223. The thin fiber 35 is in contact with the wire guiding wheel 34. The wire guiding wheel 34 is used to change the rotation direction of the thin fiber 35, so as to facilitate the winding of the thin fiber 35 around the wire winding roller 32. At the same time, a protective plate 37 is installed on one side of the bottom plate 31. The protective plate 37 is arranged on the side of the bottom plate 31 close to the cutting tool. When the cutting tool cuts the workpiece, the protective plate 37 can block part of the chips, so that the chips will not affect the operation of the pulling component 3 and the displacement component 4.

[0067] When the wire winding roller 32 unwinds the thin fiber 35, as Figure 18 shown, the thin fiber 35 begins to slowly unwind from the pulling plate 227. At this time, the torsion spring will drive the arc-shaped turning plate 224 and the arc-shaped pulling plate 225 away from the arc-shaped elastic plate 223, and the distance between the two arc-shaped pulling plates 225 will become smaller. At this time, the space on the side of the inner protective surface 213 away from the arc-shaped elastic plate 223 will become smaller. At this time, the collecting mechanism 2 can clamp small-sized workpieces, or make the inner protective surface 213 close to the workpiece by controlling the length of the unwound thin fiber 35. During the process of the arc-shaped pulling plate 225 moving away from the arc-shaped elastic plate 223, the arc-shaped pulling plate 225 pulls the end of the arc-shaped elastic plate 223 through the end protective surface 212, so that one end of the arc-shaped elastic plate 223 moves towards the direction close to the arc-shaped end plate 222, so as to avoid the tightening of the loading component 21.

[0068] When the wire winding roller 32 winds the thin fiber 35, as Figure 19As shown, the fibrils 35 pull the pulling plate 227, causing the arc-shaped pulling plate 225 to approach the arc-shaped elastic plate 223. During the process of the arc-shaped pulling plate 225 approaching the arc-shaped elastic plate 223, the arc-shaped pulling plate 225 will drive a plurality of the arc-shaped turning plates 224 to rotate in the direction approaching the arc-shaped elastic plate 223. At this time, the space on the side of the inner protective surface 213 away from the arc-shaped elastic plate 223 expands, and at this time, large-sized workpieces can be placed on one side of the inner protective surface 213. During the process of the arc-shaped pulling plate 225 approaching the arc-shaped elastic plate 223, one end of the arc-shaped pulling plate 225 will contact and squeeze the arc-shaped elastic plate 223. During the process of the arc-shaped pulling plate 225 approaching the arc-shaped elastic plate 223, the arc-shaped pulling plate 225 will drive the shape of the loading assembly 21 to become smaller, and at this time, the ability of the loading assembly 21 to receive debris will decrease. To ensure the normal debris-receiving ability of the loading assembly 21, during the process of the arc-shaped pulling plate 225 approaching the arc-shaped elastic plate 223, one end of the arc-shaped pulling plate 225 squeezes the arc-shaped elastic plate 223, causing one end of the arc-shaped elastic plate 223 to move away from the arc-shaped end plate 222. To facilitate the arc-shaped elastic plate 223 to move away from the arc-shaped end plate 222, a plurality of horizontally arranged bending openings are provided on the side of the arc-shaped elastic plate 223 away from the arc-shaped end plate 222. When the arc-shaped elastic plate 223 is subjected to the thrust of the arc-shaped pulling plate 225, the arc-shaped elastic plate 223 will bend at the bending openings, so as to enable the arc-shaped elastic plate 223 to move away from the arc-shaped end plate 222 better. The arc-shaped elastic plate 223 that moves away will drive the outer protective surface 211 away from the inner protective surface 213, so as to expand the internal space of the loading assembly 21 and ensure the debris collection effect of the loading assembly 21.

[0069] Further, to ensure the accurate pushing of the arc-shaped pulling plate 225 on the arc-shaped elastic plate 223, as Figure 20 shown, a guiding groove 2251 is provided on the end face of the arc-shaped pulling plate 225 close to the arc-shaped elastic plate 223, and an inclined slant head 2231 is fixed on the end face of the arc-shaped elastic plate 223 close to the arc-shaped pulling plate 225. When the arc-shaped pulling plate 225 approaches the arc-shaped elastic plate 223, the end of the slant head 2231 slides into the guiding groove 2251. After the slant head 2231 slides into the guiding groove 2251, the guiding groove 2251 can limit the slant head 2231, enabling the arc-shaped elastic plate 223 to be stably pushed by the arc-shaped pulling plate 225, so as to ensure the movement of the arc-shaped elastic plate 223.

[0070] The usage process of the debris collection manipulator of the present invention is as follows:

[0071] The collecting piece is fixed on the tool mounting platform 11 by screws. When the turning tool is driven to move, the collecting piece moves along with the turning tool. Then, when the turning tool cuts the chips, the collecting piece collects the chips.

[0072] When the cutting amount of the turning tool is large, that is, the debris cut from the workpiece is in blocks. At this time, the debris cut by the turning tool will be tilted and moved toward the direction close to the collecting member due to the action of inertia. At this time, the displacement component 4 drives the collecting mechanism 2 to approach the workpiece, and at the same time the pulling component 3 pulls the arc-shaped pull plate 225, so that the overall shape of the receiving component 21 tends to be vertical. At this time, the debris cut by the turning tool enters the receiving component 21.

[0073] When the cutting amount of the turning tool is small, that is, the debris cut from the workpiece is in powder form, although the powdery debris also approaches the receiving component 21 due to inertia, the trajectory of the powder movement is not fixed. At this time, the pulling component 3 loosens the fine filament 35, and the torsion spring drives the arc-shaped flip plate 224 and the arc-shaped pulling plate 225 close to the workpiece. The size of the workpiece at this time can be known through the programming of the internal processing of the CNC lathe 1, that is, the CNC lathe 1 also controls the collecting piece with programming instructions, so that the collecting piece absorbs the debris. By placing the collecting mechanism 2 close to the workpiece, the amount of powder debris spreading outward is reduced. At the same time, the receiving component 21 absorbs the powder debris with the help of an air pump to capture as much debris as possible.

[0074] By controlling the collecting piece through the programming instructions inside the CNC lathe 1, the collecting piece adjusts its shape according to the different positions of the workpiece, so that the collecting piece can better collect debris; when the collecting piece encounters a part where the workpiece size is enlarged, the collecting piece moves away from the workpiece; when the collecting piece encounters a part where the workpiece size is reduced, the collecting piece moves closer to the workpiece; when the cutting amount of the turning tool is large, the collecting piece changes its shape, so that the arc-shaped pull plate 225 is away from the workpiece, and the receiving component 21 is moved closer to the vertical direction; when the cutting amount of the turning tool is small, the collecting piece changes its shape, so that the arc-shaped pull plate 225 is close to the workpiece, and the receiving component 21 is gradually bent to approach the workpiece.

[0075] Example 2

[0076] Considering that in Example 1, the manipulator is arranged on the side of the tool mounting table 11 close to the chuck, according to the processing requirements and the different geometric angles of the tool, when the turning tool cuts the workpiece, the chips flow to the side of the processed surface (the right side), that is, splash in the direction away from the collecting member. At this time, the collecting member cannot effectively collect the chips. In order to enable the collecting member to collect the chips in the opposite direction of Example 1, this embodiment is improved on the basis of Example 1, such as Figures 21 to 22As shown, a flipping mechanism 5 is installed on the tool mounting table 11, and the displacement assembly 4 is installed on the flipping mechanism 5. When the chip flow direction is towards the machined surface side (right side), the flipping mechanism 5 is used to drive the manipulator to flip 180°, flipping to the other side of the turning tool, so that the collecting member can collect the chips cut at this time.

[0077] Further, the flipping mechanism 5 includes a semi-circular ring frame 51 arranged on the upper side of the tool mounting table 11. The semi-circular ring frame 51 is in an arc shape, and its radian angle is greater than 180°. Both ends of the semi-circular ring frame 51 are fixed with connecting blocks 53 by screws, and the two connecting blocks 53 are fixed on the opposite side walls of the tool mounting table 11 by screws; a moving frame 54 is slidably arranged on the semi-circular ring frame 51, and the connecting frame 45 and the moving frame 54 are fixedly connected by screws. A driving gear 55 is rotatably installed inside the moving frame 54, and a flipping motor 56 for driving the driving gear 55 to rotate is installed on one side of the moving frame 54. The flipping motor 56 can rotate in both directions; a semi-toothed ring 52 is fixedly installed on the outer side wall of the semi-circular ring frame 51, and the driving gear 55 meshes with the semi-toothed ring 52.

[0078] When the chip flow direction is towards the machined surface side (right side), the flipping motor 56 drives the driving gear 55 to rotate, so that the driving gear 55 meshes with the semi-toothed ring 52 to make the moving frame 54 slide on the semi-circular ring frame 51. During the sliding process of the moving frame 54, the collecting member is driven to flip from one end of the semi-circular ring frame 51 to the other end, so as to complete the effect of adjusting the position of the collecting member, enabling the collecting member to collect the chips of the workpiece when cutting when the chip flow direction is towards the machined surface side (right side).

[0079] At the same time, the radian angle of the semi-circular ring frame 51 is set to be greater than 180°, which can ensure that the moving frame 54 can rotate 180°. In this way, it is ensured that after the collecting member rotates to the specified position, the middle position of the vertical height of the deformation assembly 22 can still be at the same height as the turning tool, so as to ensure the chip collection effect of the collecting member.

[0080] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
