Description

Technical Field

[0001] This invention relates to the field of machining, and further to a cutting device and machining system for machining products. Background Technology

[0002] In the field of machining, especially when processing products with rotating characteristics or requiring circumferential cutting operations (such as pipes, bars, and disc-shaped parts), turning, milling, or special rotary cutting devices are often used.

[0003] Traditional machining equipment, such as conventional lathes or machining centers, typically uses a workpiece rotation and linear tool feed to cut external diameters, internal holes, or end faces. However, for large, heavy, or difficult-to-clamp and rotate products (such as long shaft parts, large pipe fittings, or irregularly shaped structural parts), using workpiece rotation not only places extremely high demands on the machine tool's drive power and load-bearing capacity but also presents clamping difficulties and can easily affect machining accuracy and safety due to the large centrifugal force of the rotating workpiece. Therefore, existing technologies have developed machining methods that involve tool rotation and workpiece fixation. This involves rotating the tool spindle to make the cutting edge revolve around the workpiece's central axis, thereby achieving circumferential machining of a stationary workpiece.

[0004] In existing technologies, when a product is fixed and the axis of the cutting device is also fixed, and the product needs to be machined using the cutting device, the tool typically operates along a single radial or axial direction, resulting in a fixed and singular cutting path. Furthermore, because the tool in the cutting device is usually clamped and fixed to a rotating component within the device, it is susceptible to the influence of cutting forces during product machining, leading to unstable cutting conditions and consequently, compromised machining accuracy. Summary of the Invention

[0005] To address the aforementioned technical problems, the present invention aims to provide a cutting device and a processing system for machining products. The cutting device of this application can adapt to various processing conditions when machining a fixed product, offering high cutting flexibility and precision.

[0006] To achieve the above objectives, a first aspect of the present invention provides a cutting apparatus for machining products, comprising:

[0007] A rotating housing has a telescopic channel and a guide space. The telescopic channel extends between a first end and a second end of the rotating housing. The extension direction of the guide space has a preset angle with the extension direction of the telescopic channel. A cutting opening communicating with the guide space is provided on the second end.

[0008] A telescopic spindle, one end of which is telescopically disposed within the telescopic channel;

[0009] A cutting mechanism, comprising a transmission block and a cutting element, wherein the transmission block is slidably disposed within the guide space, the cutting element is disposed on the transmission block, and a portion of the cutting element passes through the cutting opening and extends to the outside;

[0010] The product is suitable for being fixed in a preset position. When the telescopic spindle extends or retracts relative to the rotating housing, it can drive the transmission block to move along the length extension direction of the guide space, thereby driving the cutting part to move synchronously.

[0011] In some embodiments, the rotating housing includes an upper rotating housing and a lower rotating housing, which are integrally connected, and the telescopic channel communicates with the guide space;

[0012] The conductive block is provided with a guide groove, one end of the telescopic main shaft extends into the guide space, and a first guide protrusion extends into the guide groove;

[0013] When the telescopic spindle extends or retracts relative to the rotating housing, the first guide protrusion slides in the guide groove, causing the transmission block to slide in the length extension direction of the guide space, and the cutting part slides synchronously.

[0014] In some embodiments, the rotating housing includes an upper rotating housing and a lower rotating housing, which are separately connected. The telescopic channel is formed in the upper rotating housing, and the guide space is formed in the lower rotating housing.

[0016] The cutting mechanism includes a guide member, one end of which is connected to the upper rotating housing, and the other end passes through the guide opening and extends into the guide space. The guide member has a guide groove communicating with the guide space, and the transmission block has a second guide protrusion extending into the guide groove.

[0017] When the telescopic spindle extends or retracts relative to the rotating housing, controlling the extension or retraction of the lower rotating housing can drive the first guide protrusion to slide within the guide groove, so that the conductive block slides along the length extension direction of the guide space, and the cutting part slides synchronously.

[0018] In some embodiments, the telescopic channel is coaxial with the rotating housing, the guide groove is a guide inclined groove, and the extending direction of the guide inclined groove is perpendicular to the axial direction of the rotating housing; or

[0019] The telescopic channel is coaxial with the rotating housing, the guide groove is a guide inclined groove, and the length extension direction of the guide space is at a preset angle to the axial direction of the rotating housing; or

[0020] The telescopic channel is coaxial with the rotating housing, and the guide groove is an arc-shaped guide groove. The extension direction of the arc-shaped guide groove has a preset angle with the axial direction of the rotating housing.

[0021] In some embodiments, the cutting element is disposed at one end of the transmission block along its length extension direction. The cutting element includes a cutting block and a cutting tool. In the length extension direction of the guide space, the cutting block is disposed on one side of the transmission block. A portion of the cutting block passes through the cutting opening and extends to the outside. One end of the cutting tool is connected to the cutting block, and the other end extends toward the axis of the rotating housing.

[0022] In some embodiments, in the direction of the guide space length extension, two extension openings are formed at both ends of the rotating housing, one of which communicates with the cutting opening;

[0023] The telescopic spindle extends and retracts relative to the rotating housing, causing the transmission block to slide along the length extension direction of the guide space, and a portion of the cutting element can extend out of the extension opening.

[0024] In some embodiments, the cutting mechanism includes a counterweight block disposed at the end of the transmission block away from the cutting element and at the bottom end of the transmission block.

[0025] In some embodiments, the cutting device includes a machining sleeve with a rotating channel therein, and the rotating housing, the telescopic spindle, and the cutting mechanism are synchronously and rotatably disposed in the rotating channel.

[0026] In some embodiments, at the second end of the rotating housing, an annular protrusion extends outward from the outer side of the rotating housing in a direction away from its axis, and a positioning groove is formed on the side of the annular protrusion away from the second end, and a positioning protrusion extends into the positioning groove of the processing sleeve.

Detailed Implementation

[0044] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0045] To keep the drawings concise, each figure only schematically shows the parts relevant to the invention, and these do not represent the actual structure of the product. Furthermore, to facilitate understanding, in some figures, only one of components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0046] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0047] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0048] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0049] See Figures 1 to 4 The first aspect of the present invention provides a cutting device 100 for processing a product 101. The cutting device 100 includes a rotating housing 1, in which a telescopic channel 131 is provided, extending between a first end 11 and a second end 12 of the rotating housing 1. The cutting device 100 includes a telescopic spindle 2, one end of which is telescopically disposed within the telescopic channel 131.

[0050] Specifically, the telescopic channel 131 provides a space for the telescopic spindle 2 to extend and retract. In a preferred embodiment, one end of the telescopic channel 131 is located at the first end 11, and the other end extends along the axial direction of the rotating housing 1 towards the second end 12. Therefore, in this embodiment, the telescopic spindle 2 and the telescopic channel 131 are coaxially arranged. At this time, the telescopic spindle 2, the telescopic channel 131, and the rotating housing 1 are coaxially arranged, so when the rotating housing 1 rotates at high speed, the shaking and vibration caused by the eccentricity of the telescopic spindle 2 can be effectively avoided.

[0051] Further, see Figure 2 , Figure 5 , Figure 6 , Figure 9 , Figure 13 as well as Figure 14 The rotating housing 1 further includes a guide space 141, the extension direction of which has a preset angle with the extension direction of the telescopic channel 131. Meanwhile, the cutting device 100 also includes a cutting mechanism 3, which includes a transmission block 31 slidably disposed within the guide space 141.

[0052] Specifically, the guide space 141 is used to accommodate the conductive block 31 and provide guidance for the conductive block 31. It should be noted that the telescopic spindle 2 can slide within the telescopic channel 131 to drive the conductive block 31 to slide within the guide space 141 along the length extension direction of the guide space 141.

[0053] At this time, there is a preset angle between the extending direction of the guide space 141 and the extending direction of the telescopic channel 131. The preset angle may be, but is not limited to, an acute angle. In some other optional embodiments, the preset angle may also be an obtuse angle, a right angle, or 180 degrees.

[0054] It should be noted that, for reference Figures 5 to 14At the second end 12 of the rotating housing 1, a cutting opening 142 communicating with the guide space 141 is provided. The cutting mechanism 3 also includes a cutting element 32. Specifically, the cutting element 32 is mounted on the guide block 31, and a portion of the cutting element 32 can pass through the cutting opening 142 and extend to the outside.

[0055] Specifically, product 101 is adapted to be fixed in a preset position, and the cutting element 32 is mainly used to cut product 101 to form a corresponding shape and structure on product 101. The cutting opening 142 can be used to provide an opening space for the cutting element 32 to pass through, so that the cutting element 32 can extend out of the rotating housing 1, thereby better cutting product 101.

[0056] In a preferred embodiment, the length extension direction of the cutting opening 142 is the same as the extension direction of the guide space 141, so as to avoid the cutting member 32 being obstructed during its movement within the cutting opening 142.

[0057] Furthermore, when the telescopic spindle 2 extends or retracts relative to the rotating housing 1, it can drive the transmission block 31 to move along the length extension direction of the guide space 141. The cutting element 32 connected to the transmission block 31 can move in the same direction along the length extension direction of the guide space 141, and the movement path of the cutting element 32 is the cutting path of the product 101. Compared with the prior art where the cutting element 32 processes the product 101 along a single radial or axial direction, in this application, the length extension direction of the guide space 141 has a preset angle with the length extension direction of the telescopic spindle 2. Therefore, the length extension direction of the guide space 141 is adjustable, and the cutting element 32 sliding along the length extension direction of the guide space 141 has multiple cutting paths. It can adapt to various processing states and process the product 101 under various complex working conditions, with high cutting flexibility. Meanwhile, since the cutting part 32 is limited by the inner wall of the guide space 141 during the sliding process, a full-stroke surface contact constraint is formed on the cutting part 32, which effectively reduces the vibration of the cutting part 32 during the processing of the product 101 and improves the processing accuracy.

[0058] See Figures 4 to 9 In a preferred embodiment, the rotating housing 1 includes an upper rotating housing 13 and a lower rotating housing 14, which are integrally connected. The telescopic channel 131 communicates with the guide space 141 so that one end of the telescopic spindle 2 extends from the telescopic channel 131 into the guide space 141.

[0059] In this embodiment, the conductive block 31 has a guide groove 311, and the telescopic main shaft 2 extending into the guide space 141 can have a first guide protrusion 21 extending into the guide groove 311. At this time, the telescopic main shaft 2 and the first guide protrusion 21 are in a transmission engagement.

[0060] It should be noted that, preferably, see [reference]. Figure 5 The conductive block 31 has an expansion groove 313 located away from the second end 12. The expansion groove 313 communicates with the guide groove 3111. One end of the telescopic main shaft 2 extends into the expansion groove 313 and extends the first guide protrusion 21 into the guide groove 311. In this embodiment, the telescopic main shaft 2 has a simple structure. A threaded channel can be provided on the telescopic main shaft 2. The first guide protrusion 21 engages with the inner wall of the threaded channel through a threaded connection. This design is simple and easy to install and maintain. Furthermore, the upper rotating housing 13 and the lower rotating housing 14 can be integrally cast or integrally formed using bolt fixing or other methods.

[0061] Specifically, in the first preferred embodiment, the width dimension of the guide space 141 matches the width dimension of the conduction block 31, and the height dimension of the guide space 141 matches the height dimension of the conduction block 31. Therefore, the inner wall of the guide space 141 can limit the conduction block 31, allowing it to move only along the length extension direction of the guide space 141. When the telescopic spindle 2 extends or retracts relative to the rotating housing 1, the first guide protrusion 21 slides within the guide groove 311, thereby causing the conduction block 31 to slide along the length extension direction of the guide space 141. At this time, the cutting element 32 can slide synchronously, thereby cutting the product 101 along different paths.

[0062] In the first embodiment of this example, see 4 to Figure 7 The telescopic channel 131 is coaxial with the rotating housing 1. The guide groove 311 is a guide inclined groove 3111. The length extension direction of the guide space 141 is perpendicular to the length extension direction of the telescopic channel 131. The telescopic main shaft 2 extends and retracts relative to the rotating housing 1, driving the transmission block 31 to slide along the length extension direction of the guide space 141 under the guidance of the guide groove 311, so that the cutting part 32 cuts the plane of the product 101 in a direction perpendicular to the axis of the rotating housing 1.

[0063] In the second embodiment of this example, see Figure 8 and Figure 9The telescopic channel 131 is coaxial with the rotating housing 1. The guide groove 311 is a guide inclined groove 3111. The length extension direction of the guide space 141 forms a preset angle with the length extension direction of the telescopic channel 131. The preset angle can be any one of an acute angle, an obtuse angle, or an acute angle. The telescopic spindle 2 extends and retracts relative to the rotating housing 1, driving the transmission block 31 to slide along the length extension direction of the guide space 141 under the guidance of the guide groove 311, so that the cutting part 32 cuts the product 101 along the length extension direction of the guide space 141.

[0064] When the preset angle is an acute or obtuse angle, the cutting part 32 can perform oblique cutting on the product 101. Those skilled in the art can adjust the cutting angle of the cutting part 32 by adjusting the preset angle.

[0065] Meanwhile, the preset angle can also be 180 degrees. When the preset angle is 180 degrees, the length extension direction of the telescopic channel 131 and the length extension direction of the guide space 141 are arranged parallel, and the cutting part 32 processes the product 101 along the guide space 141. The specific processing method can be drilling, etc.

[0066] In the third embodiment of this example, the telescopic channel 131 is coaxial with the rotating housing 1, and the guide groove 311 is an arc-shaped guide groove 3112. At this time, the length extension direction of the guide space 141 is at a preset angle with the length extension direction of the telescopic channel 131. The preset angle is any angle. The telescopic main shaft 2 extends and retracts relative to the rotating housing 1, driving the transmission block 31 to slide along the length extension direction of the guide space 141 under the guidance of the guide groove 311. The cutting part 32 cuts the product 101 synchronously.

[0067] It should be noted that, in this embodiment, since the arc-shaped guide groove 3112 is generally arc-shaped, when the telescopic spindle 2 extends and retracts relative to the rotating housing 1, the lower rotating housing 14 extends and retracts relative to the upper rotating housing 13. The second guide protrusion 312 arranged on the transmission block 31 can move within the arc-shaped guide groove 3112, allowing the transmission block 31 and the cutting element 32 to slide along the length extension direction of the guide space 141 while moving towards or away from the upper rotating housing 13. At this time, the transmission block 31 and the cutting element 32 slide at varying speeds along the length extension direction of the guide space 141 under the guidance of the arc-shaped guide groove 3112. Specifically, when the second guide protrusion 312 slides closer to the center of the arc-shaped guide groove 3112, the sliding speed of the conductive block 31 and the cutting element 32 in the length extension direction within the guide space 141 decreases from fast to slow. When the second guide protrusion 312 slides away from the center of the arc-shaped guide groove 3112, the sliding speed of the conductive block 31 and the cutting element 32 in the length extension direction within the guide space 141 increases from slow to fast. At this time, the cutting path of the cutting element 32 on the product 101 is an arc-shaped cut.

[0068] It should be noted that, in this embodiment, since the arc-shaped guide groove 3112 is generally arc-shaped, when the telescopic spindle 2 extends or retracts relative to the rotating housing 1, the first guide protrusion 21 arranged on the telescopic spindle 2 moves within the arc-shaped guide groove 3112, causing the transmission block 31 and the cutting element 32 to slide at varying speeds along the length extension direction of the guide space 141 under the guidance of the arc-shaped guide groove 3112. Specifically, when the first guide protrusion 21 slides closer to the center position of the arc-shaped guide groove 3112, the sliding speed of the transmission block 31 and the cutting element 32 in the length extension direction within the guide space 141 decreases from fast to slow; when the first guide protrusion 21 slides away from the center position of the arc-shaped guide groove 3112, the sliding speed of the transmission block 31 and the cutting element 32 in the length extension direction within the guide space 141 increases from slow to fast. This better adapts to the product 101 that requires localized finishing.

[0069] In the second preferred embodiment, see [reference] Figures 10 to 14 The rotating housing 1 includes an upper rotating housing 13 and a lower rotating housing 14, which are connected separately. The telescopic channel 131 is formed in the upper rotating housing 13, and the guide space 141 is formed in the lower rotating housing 14. At this time, one end of the telescopic spindle 2 passes through the telescopic channel 131 and is connected to the lower rotating housing 14.

[0070] Specifically, when the telescopic channel 131 extends or retracts relative to the rotating housing 1, the lower rotating housing 14 can extend or retract synchronously relative to the upper rotating housing 13. It should be noted that since the upper rotating housing 13 and the lower rotating housing 14 are connected separately, those skilled in the art can more easily disassemble and assemble the upper rotating housing 13 and the lower rotating housing 14 to facilitate maintenance of the rotating housing 1.

[0071] Meanwhile, a guide opening communicating with the guide space 141 is provided at one end of the lower rotating housing 14 near the upper rotating housing 13. The cutting mechanism 3 includes a guide member 33, one end of which is connected to the upper rotating housing 13, and the other end passes through the guide opening and extends into the guide space 141. The guide member 33 has a guide groove 311, and the conductive block 31 extends a second guide protrusion 312 into the guide groove 311.

[0072] Specifically, the guide groove 311 is formed on the guide member 33, and the guide groove 311 can be formed at one end of the guide member 33 extending into the guide space 141 and communicating with the guide space 141, so as to cooperate with the conductive block 31, allowing the conductive block 31 to better extend the second guide protrusion 312 into the guide groove 311. At the same time, the guide opening provides a space for the guide member 33 to pass through, ensuring that the guide member 33 can extend from the upper rotating housing 13 into the guide space 141.

[0073] It should be noted that, preferably, the second guide protrusion 312 is cylindrical in shape. When the second guide protrusion 312 slides within the guide groove 311, the contact area between the cylindrical second guide protrusion 312 and the inner wall of the guide groove 311 is small. Therefore, the friction between the second guide protrusion 312 and the inner wall of the guide groove 311 is smaller, allowing the second guide protrusion 312 to slide more effectively within the guide groove 311.

[0074] Simultaneously, as the telescopic spindle 2 extends and retracts relative to the rotating housing 1, it controls the extension and retraction of the lower rotating housing 14 relative to the upper rotating housing 13. Since the conductive block 31 is disposed within the guide space 141 in the lower rotating housing 14, the conductive block 31 also extends and retracts synchronously with the lower rotating housing 14. Furthermore, because the guide member 33 is fixedly connected to the upper rotating housing 13, and the conductive block 31 is connected to the guide member 33 via the second guide protrusion 312, the second guide protrusion 312 can slide within the guide groove 311 while the conductive block 31 moves synchronously with the lower rotating housing 14, causing the conductive block 31 to slide along the length extension direction of the guide space 141. The cutting member 32 connected to the conductive block 31 slides synchronously to achieve cutting of the product 101 along different paths.

[0075] In the first embodiment of this example, see Figures 10 to 13 The telescopic channel 131 is coaxial with the rotating housing 1. The guide groove 311 is a guide inclined groove 3111, and the length extension direction of the guide space 141 is perpendicular to the length extension direction of the telescopic channel 131. When the telescopic main shaft 2 extends or retracts relative to the rotating housing 1, it drives the lower rotating housing 14 to extend or retract relative to the upper rotating housing 13. The transmission block 31 disposed in the guide space 141 of the lower rotating housing 14 extends or retracts synchronously, and the second guide protrusion 312 in the transmission block 31 slides in the guide inclined groove 3111, thereby driving the transmission block 31 to slide along the length extension direction of the guide space 141 in the guide space 141. The cutting part 32 slides synchronously with the moving path of the transmission block 31.

[0076] Therefore, the moving path of the transmission block 31 is as follows: while moving relative to the upper rotating housing 13, it slides synchronously along the length extension direction of the guide space 141 under the guidance of the guide groove 3111, so that the cutting part 32 performs tangential cutting on the product 101.

[0077] In the second embodiment of this example, see Figure 14The telescopic channel 131 is coaxial with the rotating housing 1, the guide groove 311 is an arc-shaped guide groove 3112, and the length extension direction of the guide space 141 has a preset angle with the length extension direction of the telescopic channel 131. The preset angle can be any angle. When the telescopic spindle 2 extends or retracts relative to the rotating housing 1, it drives the lower rotating housing 14 to extend or retract relative to the upper rotating housing 13. This causes the conductive block 31 to move synchronously along the length extension direction of the guide space 141 under the guidance of the arc-shaped guide groove 3112 while moving relative to the upper rotating housing 13, thereby enabling the cutting part 32 to perform arc-shaped cutting on the product 101.

[0078] It should be noted that, in this embodiment, since the arc-shaped guide groove 3112 is generally arc-shaped, when the telescopic spindle 2 extends and retracts relative to the rotating housing 1, the lower rotating housing 14 extends and retracts relative to the upper rotating housing 13. The second guide protrusion 312 arranged on the transmission block 31 can move within the arc-shaped guide groove 3112, allowing the transmission block 31 and the cutting element 32 to slide along the length extension direction of the guide space 141 while moving towards or away from the upper rotating housing 13. At this time, the transmission block 31 and the cutting element 32 slide at varying speeds under the guidance of the arc-shaped guide groove 3112. Specifically, when the second guide protrusion 312 slides closer to the center of the arc-shaped guide groove 3112, the sliding speed of the conductive block 31 and the cutting element 32 in the length extension direction within the guide space 141 decreases from fast to slow. When the second guide protrusion 312 slides away from the center of the arc-shaped guide groove 3112, the sliding speed of the conductive block 31 and the cutting element 32 in the length extension direction within the guide space 141 increases from slow to fast. At this time, the cutting path of the cutting element 32 on the product 101 is an arc-shaped cut.

[0079] In the third embodiment of this example, the telescopic channel 131 is coaxial with the rotating housing 1, the guide groove 311 is a guide inclined groove 3111, and the length extension direction of the guide space 141 has a preset angle with the length extension direction of the telescopic channel 131. The preset angle can be any one of an acute angle, an obtuse angle, or 180°. When the telescopic main shaft 2 extends or retracts relative to the rotating housing 1, it drives the lower rotating housing 14 to extend or retract relative to the upper rotating housing 13. This causes the conductive block 31 to move relative to the upper rotating housing 13 and simultaneously slide along the length extension direction of the guide space 141 under the guidance of the guide inclined groove 3111, thereby causing the cutting part 32 to perform oblique cutting on the product 101.

[0080] Therefore, when the preset angle is an acute or obtuse angle, the cutting element 32 cuts the product 101 at an angle. Those skilled in the art can adjust the cutting angle of the cutting element 32 by adjusting the preset angle. When the preset angle is 180 degrees, the cutting element 32 can drill holes in the product 101.

[0081] In either the first preferred embodiment or the second preferred embodiment, see [reference]. Figure 5 and Figure 11 The cutting element 32 is disposed at one end of the transmission block 31 along its length extension direction. The cutting element 32 includes a cutting block 321 and a cutting tool 322. In the length extension direction of the guide space 141, the cutting block 321 is disposed on one side of the transmission block 31. Part of the cutting block 321 passes through the cutting opening 142 and extends to the outside. One end of the cutting tool 322 is connected to the cutting block 321, and the other end extends toward the axial direction of the rotating housing 1.

[0082] Specifically, the cutting block 321 is disposed at one end of the conductive block 31, and the cutting tool 322 is disposed outside the rotating housing 1 and fixed to the cutting block 321. The cutting tool 322 is mainly used to cut the product 101, and the cutting block 321 is mainly used to provide support for the connection between the cutting tool 322 and the conductive block 31.

[0083] It should be noted that, preferably, the cutting block 321 has a groove and a second through hole on one end of the outer side of the rotating housing 1. The groove and the second through hole are interconnected, and the length extension direction of the groove is consistent with the length extension direction of the guide space 141. The cutting tool 322 has a first through hole. When the cutting tool 322 is installed in the groove, the first through hole corresponds to the second through hole. Simultaneously, the inner walls of both the first and second through holes are threaded, and bolts are adapted to pass through the first and second through holes to fix the cutting tool 322 to the cutting block 321. Furthermore, one end of the cutting block 321 located within the guide space 141 can also be fixed to the transmission block 31 by bolt connection. Therefore, the cutting block 321, the transmission block 31, and the cutting tool 322 are all detachable, allowing those skilled in the art to replace the cutting tool 322 if it is damaged.

[0084] In some other embodiments, the cutting tool 322 and the cutting block 321 can also be fixed in other ways, for example: a threaded surface is provided at one end of the cutting tool 322, and a threaded groove is provided at one end of the cutting block 321 located outside the rotating housing 1, and the cutting tool 322 is threadedly engaged with the tangent block.

[0085] See Figure 5 and 11 In either the first or second preferred embodiment, the size of the cutting opening 142 is smaller than the size of the guide space 141 in the width extension direction of the guide space 141. Therefore, the cutting opening 142 and the guide space 141 form a sliding step surface 143 on the inner wall of the guide space 141. When the conductive block 31 is installed within the guide space 141, the conductive block 31 can abut against the sliding step surface 143, which can limit the conductive block 31 to prevent it from detaching from the guide space 141.

[0086] Also see Figure 6 and Figure 12 In the length extension direction of the guide space 141, two extension openings 144 are opened at both ends of the rotating housing 1, one of which is connected to the cutting opening 142.

[0087] Specifically, the extension opening 144 provides a space for the guide block 31 to pass through. Part of the guide block 31 can pass through the extension opening 144 and move to the outside of the rotating housing 1, so that the guide block 31 can have a longer travel distance in the length extension direction of the guide space 141, thereby making the cutting path of the cutting element 32 longer.

[0088] In a first preferred embodiment, the telescopic spindle 2 extends and retracts relative to the rotating housing 1. During this process, the first guide protrusion 21 extends and retracts synchronously, causing it to slide within the guide groove 311. The first guide protrusion 21 abuts against the inner wall of the guide groove 311 and pushes the transmission block 31 to slide along the length extension direction of the guide space 141. Simultaneously, the cutting element 32 disposed at one end of the transmission block 31 can extend beyond the extension opening 144 as the transmission block 31 moves, thus lengthening the cutting path of the product 101.

[0089] In a second preferred embodiment, the telescopic spindle 2 extends and retracts relative to the rotating housing 1. During this time, the lower rotating housing 14 slides synchronously relative to the upper rotating housing 13, causing the guide block 31 to slide synchronously relative to the upper rotating housing 13. Simultaneously, since the guide member 33 is fixed to the upper rotating housing 13, as the guide block 31 slides relative to the upper rotating housing 13, its second guide protrusion 312 can abut against the inner wall of the guide groove 311, pushing the guide block 31 to slide along the length extension direction of the guide space 141. Simultaneously, the cutting member 32 disposed at one end of the guide block 31 can extend beyond the extension opening 144 as the guide block 31 moves, making the cutting path of the product 101 longer.

[0090] In either the first preferred embodiment or the second preferred embodiment, see [reference]. Figure 11 The cutting mechanism 3 includes a counterweight 34, which is disposed at the end of the transmission block 31 away from the cutting part 32 and at the bottom end of the transmission block 31.

[0091] Specifically, the counterweight 34 has a certain weight. In the preferred embodiment, the cutting element 32 is located at one end of the transmission block 31. The weight of the cutting element 32 causes one side of the transmission block 31 to be unbalanced. When the rotating housing 1 rotates as a whole, thereby causing the cutting element 32 to rotate, the unbalanced rotating housing 1 will generate centrifugal force. If the cutting element 32 is used for a long time, it will cause cutting instability, thus reducing the precision of the product 101 during processing. Therefore, the counterweight 34 is located at the end of the transmission block 31 away from the cutting element 32. In this case, the counterweight 34 plays a role in balancing the weight, allowing the cutting device 100 to process the product 101 with better accuracy.

[0092] In a preferred embodiment, see [reference] Figures 1 to 3 The cutting device 100 includes a processing sleeve 4, in which a rotating channel 41 is provided. The rotating housing 1, the telescopic spindle 2, and the cutting mechanism 3 are synchronously and rotatably arranged in the rotating channel 41.

[0093] Therefore, in the first preferred embodiment, when the rotating housing 1 rotates within the rotating channel 41, since the upper rotating housing 13 and the lower rotating housing 14 are integrally connected, they rotate synchronously. At this time, as described above, the conductive block 31 is limited by the guide space 141, and the conductive block 31 can only slide along the length extension direction of the guide space 141. The telescopic main shaft 2 extends a first guide protrusion 21 into the guide groove 311 in the conductive block 31, and the first guide protrusion 21 is arranged along the width extension direction of the guide space 141.

[0094] Therefore, the first guide protrusion 21 can mate with the inner wall of the guide groove 311, and the first guide protrusion 21, which extends along the width of the guide space 141, can interlock with the conductive block 31, which extends along the length of the guide space 141, in the radial direction of the rotating housing 1. Thus, when the rotating housing 1 rotates along its axis, the telescopic spindle 2, the conductive block 31, and the cutting element 32 rotate synchronously.

[0095] Simultaneously, as the cutting part 32 rotates along the rotating housing 1, the extension or retraction of the telescopic spindle 2 relative to the rotating housing 1 drives the transmission block 31 to slide in the length extension direction of the guide space 141, thereby causing the cutting part 32 to slide. This allows the cutting part 32 to move along the cutting path while rotating, thus completing the processing of the product 101.

[0096] When the telescopic spindle 2 extends, the first guide protrusion 21 moves forward accordingly, generating an interaction force with the inclined surface of the guide groove 3111. This force can be decomposed into a component along the axial direction of the telescopic spindle 2 and a component perpendicular to that axial direction. The component perpendicular to the axial direction pushes the transmission block 31 to slide along the guide space 141, thereby converting the axial displacement of the telescopic spindle 2 into the radial feed of the cutting element 32. The inclination angle of the guide groove 3111 determines this conversion ratio.

[0097] In the second embodiment, the upper rotating housing 13 and the lower rotating housing 14 are connected separately, and the telescopic main shaft 2 is connected to the lower rotating housing 14. Therefore, the lower rotating housing 14 can extend and retract synchronously with the extension and retraction of the telescopic main shaft 2.

[0098] Furthermore, since the guide member 33 can be fixedly connected to the upper rotating housing 13, and the guide member 33 is provided with a guide groove 311, the conductive block 31 is limited by the guide space 141 in the lower rotating housing 14, and the conductive block 31 is connected to the upper rotating housing 13 through the guide member 33.

[0099] Meanwhile, the conductive block 31 is disposed within the guide space 141 and is limited by the inner wall of the guide space 141, so that the conductive block 31 can only slide along the length extension direction of the guide space 141. Furthermore, the extension direction of the second extending protrusion is the same as the width extension direction of the guide space 141; therefore, the second extending protrusion limits the conductive block 31 to prevent it from detaching from the guide space 141.

[0100] Therefore, in the radial direction of the rotating housing 1, the guide member 33 can limit the upper rotating housing 13 and the lower rotating housing 14. When the rotating housing 1 rotates along its axis, the telescopic spindle 2, the transmission block 31, and the cutting member 32 rotate synchronously.

[0101] Simultaneously, as the cutting part 32 rotates along the rotating housing 1, the extension or retraction of the telescopic spindle 2 relative to the rotating housing 1 drives the lower rotating housing 14 to extend or retract synchronously, thereby driving the transmission block 31 to extend or retract synchronously. Under the influence of the inner wall of the guide groove 311 on the guide member 33, the transmission block 31 slides in the length extension direction of the guide space 141, driving the cutting part 32 to slide. As the cutting part 32 rotates, it moves along the cutting path to complete the processing of the product 101.

[0102] See Figure 3 At the second end 12 of the rotating housing 1, an annular protrusion 15 extends from the outer side of the rotating housing 1 away from its axis. A positioning groove 151 is provided on the side of the annular protrusion 15 away from the second end 12. A positioning protrusion 42 extends into the positioning groove 151 of the processing sleeve 4.

[0103] Specifically, the positioning protrusion 42 and the positioning groove 151 cooperate to provide positioning for the rotating housing 1 when it is installed on the processing sleeve 4, so as to prevent the installation of the rotating housing 1 and the processing sleeve 4 from being misaligned. At the same time, the positioning protrusion 42 and the positioning groove 151 are coaxially arranged. When the rotating housing 1 rotates relative to the processing sleeve 4, the positioning protrusion 42 can rotate relative to the positioning groove 151, so as to avoid the positioning protrusion 42 limiting the rotation of the rotating housing 1.

[0104] It should be noted that a mating bearing 43 may be arranged between the processing sleeve 4 and the rotating housing 1. The mating bearing 43 is located within the rotating channel 41, and its outer ring is fixed to the inner wall surface of the processing sleeve 4, while its inner ring is fixed to the outer wall surface of the rotating housing 1. The mating bearing 43 allows for smoother rotation of the rotating housing 1 relative to the processing sleeve 4. Simultaneously, the mating bearing 43 also serves to fix the rotating housing 1 and the processing sleeve 4.

[0105] A second aspect of this application provides a machining system including the cutting device described in the first aspect of this application. The machining system also includes the product 101, which can be fixed at any suitable position within the machining system, and the cutting device can also be fixed at any suitable position within the machining system.

[0106] When the cutting device and the product 101 are aligned, and the cutting device needs to process the product 101, the rotating housing 1 is adapted to rotate within the processing sleeve 4 to drive the cutting mechanism 3 to rotate. Simultaneously, the telescopic spindle 2 extends or retracts, allowing the guide block 31 to slide along the length of the guide space 141, and the cutting element 32 to slide synchronously, forming a cutting path to complete the cutting of the product 101.

The advantages of the present invention have been fully and effectively demonstrated.
