Description

Technical Field

[0001] This disclosure relates to the field of machining tools, and in particular to cutting machines and machining devices. Background Technology

[0002] A miter saw is a widely used power tool for cutting materials. It utilizes a high-speed rotating circular saw blade to cut materials, offering high efficiency and ease of use. Currently, there are many types of miter saws available, including those with and without drawbars, single-millimeter and double-millimeter models; however, they all share a common feature: their saw heads essentially swing up and down around a fixed axis to complete the sawing operation. This design offers numerous advantages, such as simple and reliable structure, ease of manufacturing and operation. However, this type of miter saw significantly limits its integration with other mechanical equipment and hinders further improvements in miter saw technology to achieve automated control. Utility Model Content

[0003] This disclosure provides a cutting machine including a rotating cutting blade for cutting a workpiece, the rotating cutting blade moving linearly toward and away from the workpiece during the cutting operation.

[0004] In some embodiments, the cutting machine further includes a head mechanism and a moving mechanism. The head mechanism houses the rotating cutting blade, and the moving mechanism drives the head mechanism to move vertically up and down, thereby causing the rotating cutting blade to move in a straight line toward and away from the workpiece.

[0005] In some embodiments, the moving mechanism includes a rocker arm assembly, the rocker arm assembly including a rocker arm body and a guide rod disposed in the rocker arm body, the head mechanism being connected to the guide rod to cause the rotating cutting blade to move linearly toward and away from the workpiece under the guidance of the guide rod.

[0006] In some embodiments, the rocker arm assembly further includes a lifting rod, which is hinged at a first end to the rocker arm body and at a second end to the head mechanism, and a first elastic element is provided in the middle of the lifting rod to apply a biasing force to bias the head mechanism to a raised position.

[0007] In some embodiments, the second end of the lifting rod is provided with a waist-shaped groove.

[0008] In some embodiments, when subjected to downward pressure, the head mechanism overcomes the biasing force applied by the first elastic element and moves downward toward the workpiece under the guidance of the guide rod; and when the downward pressure is released, the head mechanism returns to the raised position under the biasing force of the first elastic element.

[0009] In some embodiments, the head mechanism includes a frame having a guide sleeve that engages with the guide rod, the guide sleeve moving along the guide rod causing the rotating cutting blade to move linearly toward and away from the workpiece.

[0010] In some embodiments, a linear bearing is provided inside the guide sleeve.

[0011] In some embodiments, the head mechanism includes a protective cover assembly, the protective cover assembly including a movable cover portion and an opening / closing operation portion, the opening / closing operation portion driving the movable cover portion to move between a closed position and a ready position, in the closed position, the movable cover portion causing the protective cover assembly to cover at least a portion of the rotating cutting blade, and in the ready position, the movable cover portion causing a portion of the rotating cutting blade to be exposed.

[0012] In some embodiments, the head mechanism further includes a motor assembly and a handle assembly connected to the frame, the motor assembly providing power for the cutting operation of the rotating cutting blade.

[0013] In some embodiments, the opening and closing operation unit includes a crank, a first link and a second link, the first link being connected between the crank and the second link, and the second link being hinged to the movable cover portion.

[0014] In some embodiments, the opening / closing operation unit further includes a second elastic element that biases the movable cover portion downward.

[0015] In some embodiments, a first end of the first link is fixedly connected to the crank handle, a second end of the first link is connected to a first end of the second link via a movable shaft, and a second end of the second link is hinged to the movable cover portion.

[0016] In some embodiments, the protective cover assembly further includes a protective cover groove in which the movable shaft moves up and down when the crank is driven.

[0017] In some embodiments, the second connecting rod is generally arc-shaped and has an arc-shaped groove. The movable shaft is installed in the arc-shaped groove. When the protective cover assembly contacts the workpiece, the arc-shaped groove restricts the second connecting rod from moving along the movable shaft to drive the movable cover part to move.

[0018] In some embodiments, the cutting machine further includes a dust guide that is concentrically fitted onto the protective cover assembly with respect to the rotation axis of the rotating cutting blade.

[0019] This disclosure also provides a processing apparatus, which includes: the above-described cutting machine; and a base for supporting the cutting machine.

[0020] In this disclosure, cutting is performed by making the rotating cutting blade move in a straight line toward and away from the workpiece during the cutting operation. This makes the working trajectory of the rotating cutting blade the same as that of the working edge of other machines (such as drilling machines), thereby laying the foundation for expanding the integration of cutting machines with other mechanical equipment or realizing the automatic control of cutting machines.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solutions of this disclosure, the technical solutions of this disclosure will be described in detail below with reference to the accompanying drawings.

[0027] Exemplary embodiments will be described more fully below with reference to the accompanying drawings; however, these exemplary embodiments may be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will enable those skilled in the art to fully understand the scope of this disclosure.

[0028] Where there is no conflict, the various embodiments of this disclosure and the features thereof in the embodiments may be combined with each other.

[0029] As used herein, the term “and / or” includes any and all combinations of one or more related enumerated entries.

[0030] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this disclosure. As used herein, the singular forms “a” and “the” are also intended to include the plural forms unless the context clearly indicates otherwise. It will also be understood that when the terms “comprising” and / or “made of” are used in this specification, the presence of the stated feature, integral, step, operation, element, and / or component is specified, but the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or groups thereof is not excluded.

[0031] The embodiments described herein can be described with reference to plan views and / or cross-sectional views using the ideal schematic diagrams of this disclosure. Therefore, the example illustrations can be modified according to manufacturing techniques and / or tolerances. Therefore, the embodiments are not limited to those shown in the drawings, but include modifications to configurations formed based on manufacturing processes. Therefore, the areas illustrated in the drawings are schematic in nature, and the shapes of the areas shown in the figures illustrate specific shapes of areas of an element, but are not intended to be limiting.

[0032] Unless otherwise specified, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art.

[0033] A beveling saw is a cutting tool capable of both straight and bevel cutting, widely used across various industries. It can cut not only non-ferrous metals but also non-metallic materials such as wood. When cutting a workpiece, simply hold the handle and place the workpiece on the worktable to begin the cutting operation. It offers advantages such as high cutting speed and portability. However, existing beveling saws are designed so that the cutting head essentially swings up and down around a fixed axis to complete the cutting work, causing the rotating cutting blade to move in an arc-shaped trajectory when in contact with the workpiece. This arc-shaped trajectory differs from the movement trajectory of most mechanical actuators, significantly limiting the integration of beveling saws with other mechanical equipment and hindering further improvements in beveling saws to achieve automated control. Therefore, there is a need in this field to improve beveling saws to address the aforementioned problems.

[0034] Figure 1 This is a schematic perspective view of the cutting machine 1 according to an embodiment of the present disclosure. Figure 1The installation state of the cutting machine 1 according to an embodiment of this disclosure is shown, wherein, for ease of description, the Z-axis corresponds to the upward direction, the Y-axis corresponds to the forward direction, and the X-axis corresponds to the rightward direction. In this specification, unless otherwise indicated, the X, Y, and Z axes all refer to the aforementioned directions. However, those skilled in the art will understand that in some embodiments, the X-axis may also correspond to the leftward direction as needed.

[0035] Firstly, referring to Figure 1 This disclosure provides a cutting machine 1, which includes a rotating cutting blade 2 for cutting a workpiece. During the cutting operation, the rotating cutting blade 2 moves in a straight line toward and away from the workpiece.

[0036] In this disclosure, cutting is performed by causing the rotating cutting blade 2 to move linearly toward and away from the workpiece during the cutting operation. This makes the working trajectory of the rotating cutting blade the same as that of the working edge of other machines (such as a drilling machine), thus laying a solid foundation for the rotating cutting blade and other machines to form a multi-purpose machine. On the other hand, the linear motion trajectory also makes it easier to achieve automatic control.

[0037] In some embodiments, the cutting machine 1 further includes a head mechanism 4 and a moving mechanism 5. The head mechanism 4 houses the rotating cutting blade 2, and the moving mechanism 5 drives the head mechanism 4 to move vertically up and down, thereby causing the rotating cutting blade 2 to move in a straight line toward and away from the workpiece.

[0038] Figure 3 This is a schematic perspective view of the moving mechanism 5 of the cutting machine 1 according to an embodiment of the present disclosure. Figure 4 This is a schematic left rear perspective view of the head mechanism 4 and the moving mechanism 5 of the cutting machine 1 according to an embodiment of the present disclosure.

[0039] Reference Figure 3 The moving mechanism 5 includes a rocker arm assembly 50, which includes a rocker arm body 51 and a guide rod 52 disposed in the rocker arm body 51. (See reference...) Figure 4 The head mechanism 4 is connected to the guide rod 52, so that the rotating cutting blade 2 moves in a straight line toward and away from the workpiece under the guidance of the guide rod 52.

[0040] like Figure 3 and 4 As schematically shown, in some embodiments, the front of the rocker arm body 51 is equipped with two parallel vertical guide rods 52 for the head mechanism 4 to move up and down. In some embodiments, such as Figure 4 As exemplarily shown, the rocker arm body 51 includes an upper plate 512 and a bottom plate 514, with a guide rod 52 inserted vertically into the upper plate 512 and the bottom plate 514. Additionally, the guide rod 52 may be cylindrical, and its upper end may be connected to the upper plate 512 via a connector 516.

[0041] This disclosure achieves linear motion of the rotating cutting blade 2 toward and away from the workpiece by mounting the head mechanism 4 on two vertical guide rods 52, making the working stroke of the head mechanism 4 move up and down along the vertical guide rods 52.

[0042] Continue to refer to Figure 3 and 4 In some embodiments, the rocker arm assembly 50 further includes a lifting rod 53, which is hinged to the rocker arm body 51 at a first end 532 and connected to the head mechanism 4 at a second end 534. A first elastic element (not shown) is provided at the middle of the lifting rod 53 to apply a biasing force to bias the head mechanism 4 to an elevated position. In some embodiments, when subjected to downward pressure, the head mechanism 4 overcomes the biasing force applied by the first elastic element and moves downward toward the workpiece under the guidance of the guide rod 52; and when the downward pressure is released, the head mechanism 4 returns to the elevated position under the biasing force of the first elastic element.

[0043] The first elastic element located at the middle of the lifting rod 53 can be a tension spring, compression spring, torsion spring, etc. This first elastic element provides an upward force to the lifting rod 53. By utilizing the lever effect of the lifting rod 53, the first elastic element undergoes a small deformation, resulting in a large displacement at the second end 534 of the lifting rod 53, providing sufficient lifting space for the machine head mechanism 4. The first elastic element can be positioned in any suitable manner at the middle of the lifting rod 53 to provide a biasing force. For example, in some embodiments, the first elastic element can be positioned as a compression spring between the longitudinal center of the lifting rod 53 and the base plate 514 of the rocker arm body 51.

[0044] In some embodiments, refer to Figure 4 The first end 532 of the lifting rod 53 is hinged to the rear side of the rocker arm body 51 to pivot around the hinge axis 540. The second end 534 of the lifting rod 53 can be connected to the rear side of the head mechanism 4 (or the protective cover assembly 43). However, the specific connection position between the lifting rod 53 and the rocker arm body 51 and the head mechanism 4 is not limited, as long as the pivoting movement of the lifting rod 53 can drive the head mechanism 4 to move up and down. Additionally, refer to... Figure 3 and 4 The lifting rod 53 is formed into a stepped shape by bending twice in the middle. This shape allows the lifting rod 53 to pass between the rocker arm body 51 and the guide rod 52 and connect to the head mechanism 4, thus providing a compact structure. Those skilled in the art will understand that the lifting rod 53 can also take other shapes, as long as it can be hinged at one end to the rocker arm body 51 and connected to the head mechanism 4 at the other end.

[0045] Return to reference Figure 3In some embodiments, the second end 534 of the lifting rod 53 is provided with a first waist-shaped groove 536. The first waist-shaped groove 536 is used to connect to the head mechanism 4 via a connecting member (not shown), which is fixedly connected to the head mechanism 4 and can move along the first waist-shaped groove 536. The specific structure of the connecting member is not limited, as long as it can connect the lifting rod 53 to the head mechanism 4. In some embodiments, the connecting member can be a connecting shaft, etc. When the lifting rod 53 pivots about the hinge axis 540, the second end 534 of the lifting rod 53 drives the connecting member to move. The connecting member slides along the first waist-shaped groove 536 during movement, thereby converting the rotational motion of the second end 534 of the lifting rod 53 into the linear motion of the head mechanism 4 along the guide rod 52.

[0046] Continue to refer to Figure 4 The head mechanism 4 includes a frame 41, which has a guide sleeve 42 that cooperates with the guide rod 52. The movement of the guide sleeve 42 along the guide rod 52 causes the rotating cutting blade 2 to move linearly toward and away from the workpiece.

[0047] In some embodiments, a linear bearing (not shown) is provided inside the guide sleeve 42. The linear bearing can be any linear bearing known to those skilled in the art. The linear bearing cooperates with the guide rod 52, allowing the head mechanism 4 to move smoothly up and down.

[0048] Figure 5 This is a partial perspective view of a portion of the head mechanism 4 of the cutting machine 1 according to an embodiment of the present disclosure. In order to show the internal structure more clearly, the right half of the fixed cover portion 46 of the protective cover assembly 43 has been removed, a portion of the rotating cutting blade 2 has been cut off along curve BB, a portion of the protective cover assembly 43 has been cut off along straight line CC, and a portion of the handle assembly 48 has been cut off along curve DD.

[0049] In some embodiments, refer to Figure 5 The head mechanism 4 includes a protective cover assembly 43, which includes a movable cover portion 44 and an opening / closing operation part 45. The opening / closing operation part 45 drives the movable cover portion 44 to move between a closed position and a ready position. In the closed position, the movable cover portion 44 causes the protective cover assembly 43 to cover at least a portion of the rotating cutting blade 2. In the ready position, the movable cover portion 44 exposes a portion of the rotating cutting blade 2.

[0050] The protective cover assembly 43 also includes a fixed cover portion 46. The fixed cover portion 46 securely covers a portion of the rotating cutting blade 2. The fixed cover portion 46 and the movable cover portion 44 of the protective cover assembly 43 can surround and form a protective space to accommodate the rotating cutting blade 2, thereby covering the rotating cutting blade 2 from the sides and circumference. (See reference...) Figure 5As can be seen, the rotary cutting blade 2 is mounted on the rotation axis 90, allowing it to rotate around the rotation axis A to perform cutting operations on the workpiece. The movable cover portion 44 of the protective cover assembly 43 is concentrically fitted onto the fixed cover portion 46 with respect to the rotation axis A. When the movable cover portion 44 is in the closed position, the fixed cover portion 46 and the movable cover portion 44 cover the rotary cutting blade 2 to prevent damage from foreign objects and to prevent the operator from being accidentally scratched by the rotary cutting blade 2. When the movable cover portion 44 is in the ready position, it opens at a certain angle relative to the fixed cover portion 46, thus exposing a portion of the rotary cutting blade 2 in preparation for the cutting operation.

[0051] In some embodiments, return to reference Figure 4 The head mechanism 4 also includes a motor assembly 47 and a handle assembly 48 connected to the frame 41.

[0052] The motor assembly 47 provides power for the rotary cutting operation of the rotary cutting blade 2. The motor assembly 47 is connected to one side of the frame 41, and the protective cover assembly 43 is connected to the other side of the frame 41. In some embodiments, the guide sleeve 42 of the frame 41 is disposed on the side of the frame 41 connected to the motor assembly 47 (i.e., the side closer to the rocker arm assembly 50). In some preferred embodiments, there may be two guide sleeves 42; the guide sleeve 42 may be integrally cylindrical.

[0053] The handle assembly 48 is for the operator to hold, and the operator applies a vertical force to the handle assembly 48 to drive the head mechanism 4 to move up and down. The handle assembly 48 may be located on the upper part of the frame 41. A button for starting the motor assembly 47 may be provided on the handle assembly 48. The handle assembly 48 contains a transmission gear and an output shaft (not shown) to actuate the motor assembly 47 in response to the operator pressing the button. The transmission gear and output shaft may adopt any suitable construction known to those skilled in the art, and no specific limitation is made here.

[0054] Furthermore, the specific structure of the frame 41 is not limited, as long as it can connect the protective cover assembly 43, the motor assembly 47 and the handle assembly 48 and include a guide sleeve 42 that can move along the guide rod 52.

[0055] See below for further reference. Figure 5 In some embodiments, the opening / closing operation unit 45 includes a crank 452, a first link 454, and a second link 456. The first link 454 is connected between the crank 452 and the second link 456, and the second link 456 is hinged to the movable cover portion 44. In some embodiments, the second link 456 is hinged to the upper part of the movable cover portion 44.

[0056] By turning the crank 452, the first link 454 can be rotated. The rotation of the first link 454 in turn drives the second link 456 to move. The second link 456 eventually drives the movable cover part 44 to rotate from the closed position to the ready position.

[0057] In some embodiments, the opening / closing operation unit 45 further includes a second elastic element (not shown) that biases the movable cover portion 44 downward. The second elastic element can be a tension spring, compression spring, torsion spring, etc., as long as it provides a downward biasing force to the movable cover portion 44. This downward biasing force of the second elastic element biases the movable cover portion 44 toward a closed position (biased downward pivoting). The second elastic element can be disposed on the movable cover portion 44 in any suitable manner and configuration as needed. For example, in some embodiments, the second elastic element can be disposed as a torsion spring between the movable cover portion 44 and the rotation axis 90.

[0058] In some embodiments, the first end 458 of the first link 454 is fixedly connected to the crank 452, the second end 459 of the first link 454 is connected to the first end 461 of the second link 456 via a movable shaft 453, and the second end 462 of the second link 456 is hinged to the movable cover portion 44.

[0059] In some embodiments, the first end 458 of the first link 454 is fixedly connected to the crank handle 452 via a fixed pivot shaft, such that one end of the fixed pivot shaft is fixedly connected to the first end 458 of the first link 454, and the other end of the fixed pivot shaft is fixedly connected to the crank handle 452. Additionally, the middle portion between the two ends of the fixed pivot shaft is fitted onto the handle assembly 48.

[0060] Continue to refer to Figure 5 The second end 459 of the first connecting rod 454 is provided with a second waist-shaped groove 432, which is sleeved on the movable shaft 453.

[0061] In some embodiments, the protective cover assembly 43 further includes a protective cover recess 430 in which the movable shaft 453 moves vertically when the crank 452 is actuated. The protective cover recess 430 may be in the form of an elongated hole surrounded by ribs protruding from the surface of the fixed cover portion 46. The protective cover recess 430 may also be in the form of an oblong groove surrounded by ribs protruding from the surface of the fixed cover portion 46. In some embodiments, the protective cover recess 430 may extend vertically. However, those skilled in the art can design the extension direction of the protective cover recess 430 as needed.

[0062] When the crank handle 452 is driven to rotate, the first connecting rod 454, which is fixedly connected to the crank handle 452, rotates accordingly. When the movable shaft 453 moves up and down within the protective cover groove 430, it also slides along the second waist-shaped groove 432, thereby converting the rotational motion of the crank handle 452 into linear motion of the second end 459 of the first connecting rod 454 along the protective cover groove 430. That is, when the crank handle 452 is driven, the movable shaft 453 slides along the second waist-shaped groove 432 while moving up and down within the protective cover groove 430.

[0063] In some embodiments, the second link 456 is generally arc-shaped and has an arc groove 434. The movable shaft 453 is installed in the arc groove 434. When the protective cover assembly 43 contacts the workpiece, the arc groove 434 restricts the second link 456 from moving along the movable shaft 453 to drive the movable cover portion 44 to move.

[0064] An arcuate groove 434 is formed in the upper part of the second connecting rod 456 so that the second connecting rod 456 is sleeved with the movable shaft 453. In some embodiments, the arcuate groove 434 extends at least downward from the first end 461 of the second connecting rod 456 to the middle of the second connecting rod 456, but the specific extension range of the arcuate groove 434 is not limited and can be appropriately designed as needed. The second connecting rod 456 is hinged to the movable cover portion 44 at the lower second end 462 via a pivot connector 460.

[0065] Thus, in some embodiments, the right end of the movable shaft 453 is fitted with the arcuate groove 434 on the second connecting rod 456, the opposite left end of the movable shaft 453 is fitted with the rib surrounding the protective cover groove 430 on the fixed cover portion 46, and the middle portion of the movable shaft 453 between its two ends is fitted with the second waist-shaped groove 432 on the first connecting rod 454. In other embodiments, the following arrangement may also be adopted: the right end of the movable shaft 453 is fitted with the arcuate groove 434 on the second connecting rod 456, the opposite left end of the movable shaft 453 is fitted with the second waist-shaped groove 432 on the first connecting rod 454, and the middle portion of the movable shaft 453 between its two ends is fitted with the rib surrounding the protective cover groove 430 on the fixed cover portion 46.

[0066] In some embodiments, the cutting machine 1 further includes a dust guide 6, which is concentrically fitted onto the protective cover assembly 43 along the rotation axis A of the rotating cutting blade 2. The dust guide 6 may be concentrically fitted onto the fixed cover portion 46 of the protective cover assembly 43 along the rotation axis A of the rotating cutting blade 2. The dust guide 6 is used to collect and guide debris generated during workpiece cutting to the dust outlet 61.

[0067] In this disclosure, the dust collection rate of the cutting machine 1 can be improved by using a dust guide 6.

[0068] To enable those skilled in the art to more clearly understand the specific operation of the cutting machine 1 according to the embodiments of this disclosure, the operation method of the cutting machine 1 provided in the embodiments of this disclosure will be described in detail below through specific embodiments:

[0069] Example 1

[0070] In the cutting machine 1 disclosed herein, operation is performed by causing the head mechanism 4 to move vertically up and down. (See reference...) Figure 4 The head mechanism 4 is connected to two vertical guide rods 52 via linear bearings. Under the action of the lifting rod 53, the head mechanism 4 is in its designed highest position, i.e., the raised position, when no external force is applied. During operation, the operator applies a downward force to the head mechanism 4 through the handle assembly 48, pressing the head mechanism 4 downwards smoothly, so that the rotating cutting blade 2 can process the workpiece. If the external force is removed, the head mechanism 4 will automatically return to its highest achievable position, i.e., the raised position.

[0071] On the other hand, refer to Figure 5 During operation, before the press head mechanism 4, the crank 452 of the opening / closing operation part 45 is turned clockwise, causing the first connecting rod 454 of the opening / closing operation part 45 to rotate clockwise, thereby lifting the movable shaft 453 upward. The movable shaft 453 moves upward along the protective cover groove 430 from the bottom end of the protective cover groove 430 to the top end of the protective cover groove 430, thereby lifting the first end 461 of the second connecting rod 456 of the opening / closing operation part 45 to the top end of the protective cover groove 430. This upward lifting of the second connecting rod 456 causes the movable cover part 44 of the protective cover assembly 43 to rotate counterclockwise until the first end 461 of the second connecting rod 456 of the opening / closing operation part 45 reaches the top end of the protective cover groove 430, exposing a portion of the working teeth of the rotating cutting blade 2.

[0072] The aforementioned opening and closing operation unit 45 is a semi-active opening structure. Before the pressing head mechanism 4, the movable cover part 44 is opened to a certain angle to the ready position by external force (operator-applied force). Then, during the downward movement of the pressing head mechanism 4, the workpiece pushes against the movable cover part 44 to continue opening. The arc-shaped groove 434 on the second connecting rod 456 is the path through which the second connecting rod 456 is driven upward by the movable cover part 44. That is, when driven by the workpiece, the movable cover part 44 continues to rotate counterclockwise, causing the second connecting rod 456, sleeved on the movable shaft 453, to slide backward along the movable shaft 453. During operation, the movable cover part 4 remains in contact with the workpiece due to the biasing force of the downward pivoting of the second elastic element.

[0073] When work is paused or finished, the operation is reversed. That is, the operator raises the machine head mechanism 4 away from the workpiece, and the movable cover part 44 is biased to the ready position by the second elastic element. Then the operator turns the crank 452 of the opening and closing operation part 45 counterclockwise to return the components of the opening and closing operation part 45 and the movable cover part 44 to their original positions.

[0074] This disclosure provides a semi-active opening structure, allowing for easy operation by rotating the crank 452 only a small angle. Furthermore, this semi-active opening structure reduces the vertical distance of the cutting head mechanism 4, maximizing its conversion into effective cutting capacity, which is highly beneficial for the overall compactness of the machine. In addition, this semi-active opening structure is safer and more user-friendly; the rear section of the movable cover 4 opens via the workpiece, preventing excessive exposure of the high-speed rotating saw teeth to the operator, thus avoiding safety hazards and providing a better operating experience.

[0075] Figure 2 This is a partial perspective view of a portion of the processing apparatus 10 according to an embodiment of the present disclosure.

[0076] Secondly, referring to Figure 1 and 2 This disclosure provides a processing apparatus 10, including: a cutting machine 1; and a base 11 for supporting the cutting machine 1.

[0077] The base 11 includes a base assembly 12, a turntable assembly 13, and a backing plate 14.

[0078] The base assembly 12 is used to mount the turntable assembly 13 and the backing plate 14. The four feet at the bottom of the base assembly 12 directly contact the ground or workbench, supporting the weight of the entire machine. The base assembly 12 also has two protrusions 120 protruding from both sides.

[0079] The turntable assembly 13 is vertically (Z-axis) hinged to the base assembly 12, allowing it to swing left and right in the XY plane. The turntable assembly 13, together with the two bosses 120 of the base assembly 12, provides a plane for supporting the workpiece. The turntable assembly 13 is connected to the lower part of the rocker arm assembly 50 via a pivot 130. The rocker arm assembly 50 is longitudinally (Y-axis) hinged to the turntable assembly 13, allowing the rocker arm assembly 50 and any components mounted or connected to it to swing left and right in the XZ plane.

[0080] The backing plate 14 is fixed to the base assembly 12 and is used for positioning and supporting the workpiece.

[0081] The left-right rotation of the turntable assembly 13 in the XY plane and the left-right swing of the rocker arm assembly 50 in the XZ plane can adjust the orientation and position of the rotating cutting blade 2 relative to the workpiece positioned against the backing plate 14. Rotating the turntable assembly 13 can adjust the angle of the rotating cutting blade 2 relative to the workpiece. Swinging the rocker arm assembly 50 can adjust the position of the rotating cutting blade 2 relative to the workpiece.

[0082] In the processing apparatus 10, when the movable cover portion 44 is in the closed position, the fixed cover portion 46 and the movable cover portion 44 cover the portion of the rotating cutting blade 2 located at the front end of the back plate 14 to prevent damage to the rotating cutting blade 2 from external foreign objects and to prevent the operator from being accidentally scratched by the rotating cutting blade 2. When the movable cover portion 44 is in the ready position, the movable cover portion 44 opens at a certain angle relative to the fixed cover portion 46, thereby exposing a portion of the rotating cutting blade 2 located at the front end of the back plate 14 to prepare for the cutting operation.

[0083] Thirdly, this disclosure provides a workpiece processing method using a cutting machine 1, including a cutting step in which a vertically downward force is applied to the rotating cutting blade 2 of the cutting machine 1 to make the rotating cutting blade 2 move downward in a straight line until it contacts the workpiece for cutting.

[0084] In some embodiments, the workpiece processing method further includes a preparation step, wherein before performing the cutting step, the movable cover portion 44 of the protective cover assembly 43 of the cutting machine 1 is opened from the closed position to the preparation position by rotating the crank 452 of the protective cover assembly 43 along the first direction. In the closed position, the movable cover portion 44 covers the portion of the rotating cutting blade 2 at the front end of the back plate 14. In the preparation position, the movable cover portion 44 exposes the portion of the rotating cutting blade 2 at the front end of the back plate 14.

[0085] In some embodiments, during the cutting step, as the rotating cutting blade 2 moves downward, the movable cover portion 44 begins to contact the workpiece and is subsequently opened by the workpiece at a greater angle.

[0086] In some embodiments, during the cutting step, when the downward vertical force applied to the rotating cutting blade 2 is reduced to move the rotating cutting blade 2 upward, the opening angle of the movable cover portion 44 decreases until it returns to the ready position.

[0087] In some embodiments, the workpiece processing method further includes: completing the step of moving the movable cover portion 44 of the protective cover assembly 43 from the ready position to the closed position by rotating the crank 452 of the protective cover assembly 43 in a second direction opposite to the first direction to cover the rotating cutting blade 2 when the movable cover portion 44 returns to the ready position.

[0088] By employing the workpiece processing method described above, the rotary cutting blade 2 performs linear motion for cutting. This ensures that the working trajectory of the rotary cutting blade 2 is identical to that of the working edge of other machines (such as a drilling machine), thus laying a solid foundation for them to collectively constitute a multi-purpose machine. Furthermore, this workpiece processing method facilitates automatic control.

[0089] On the other hand, this disclosure provides a semi-active opening mode, where the crank handle 452 can be rotated at a small angle to achieve the opening operation, making it convenient to operate. Moreover, this semi-active opening mode can reduce the vertical distance of the head mechanism 4, maximizing the conversion of the vertical distance of the head mechanism 4 into effective cutting capacity, which is very beneficial to the compactness of the whole machine. In addition, this semi-active opening mode is safer and more user-friendly. The rear section of the movable cover 4 is opened by the workpiece, avoiding excessive exposure of the high-speed rotating saw teeth directly in front of the operator, thus not only avoiding safety hazards but also providing the operator with a better operating experience.
