Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

They are used only for the convenience of describing this invention and simplifying the description, and are not intended to 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 limitations on this invention.

[0051] In the description of this invention, "first feature" and "second feature" may include one or more of the features.

[0052] In the description of this invention, "a plurality of" means two or more, and "several" means one or more.

[0053] The cutting apparatus 1 according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0054] like Figures 1-15As shown, the cutting device 1 according to an embodiment of the present invention includes a main plate 100, a guide block 200, and a cutting assembly 300.

[0055] The main body plate 100 has a cutting through hole 110 and a cutting surface 120. The part 510 to be cut of the workpiece 500 extends into the cutting through hole 110 and extends beyond the cutting surface 120. The guide block 200 is connected to the main body plate 100. The cutting assembly 300 is slidably connected to the guide block 200 and has a scraper 310. The scraper 310 is used to cut the part 510 to be cut.

[0056] According to the cutting device 1 of the present invention, a cutting through hole 110 and a cutting surface 120 are provided in the main body plate 100. The part 510 to be cut of the workpiece 500 extends into the cutting through hole 110 and extends beyond the cutting surface 120. The cutting surface 120 can be one side of the main body plate 100 in the thickness direction. The cutting through hole 110 penetrates the main body plate 100 in a direction perpendicular to the cutting surface 120. The part 510 to be cut extends into the cutting through hole 110 from the other side of the main body plate 100 in the thickness direction. In this way, the main body plate 100 can limit the workpiece 500, and the part 510 to be cut can be inserted into the cutting through hole 110 and extend out of the cutting surface 120. The operator can directly determine whether the workpiece 500 is in position based on the relative position of the part 510 to be cut and the cutting surface 120, making the operation simple.

[0057] In addition, the guide block 200 is connected to the main body plate 100, and the cutting assembly 300 is slidably connected to the guide block 200 and has a scraper 310. The scraper 310 is used to cut the part to be cut 510. In this way, the guide block 200 can guide the cutting assembly 300 to move, and the cutting assembly 300 can drive the scraper 310 to move along the extension direction of the guide block 200. That is to say, the extension direction of the guide block 200 is the same as the sliding direction of the cutting assembly 300. By controlling the extension direction of the guide block 200, the movement direction of the scraper 310 can be indirectly controlled, thereby adjusting the cutting direction of the scraper 310 on the part to be cut 510 of the workpiece 500.

[0058] Therefore, by simply fixing the workpiece 500 to be processed in the processing position and pushing and pulling the cutting component 300, the part 510 to be cut of the workpiece 500 can be cut. The guide block 200 can guide the scraper 310 to cut, thereby ensuring the quality of the cut. It can achieve batch processing, has high processing efficiency, is easy to assemble, has good strength, and has a long service life.

[0059] Compared to manual cutting, the cutting device 1 of this embodiment of the invention has higher cutting consistency and a higher yield of the cutting part 510 of the workpiece 500. Compared to milling, the cutting device 1 of this embodiment of the invention will not cause a short circuit in the cutting part 510 of the workpiece 500 when cutting, which is safer and less expensive.

[0060] Thus, the cutting device 1 according to the embodiments of the present invention has the advantages of high processing efficiency, high yield, low cost and high safety.

[0061] In some specific embodiments of the present invention, such as Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the guide block 200 is connected to the two opposite sides of the main body plate 100 that are perpendicular to the cutting surface 120, and the guide block 200 extends beyond the cutting surface 120.

[0062] In this way, the guide block 200 can not only guide the cutting component 300, but the part of the guide block 200 that extends beyond the cutting surface 120 can also separate the cutting component 300 and the main body plate 100, so that there is enough space between the cutting component 300 and the main body plate 100. This space can be used to accommodate the part to be cut 510 and the scraper 310 of the cutting component 300, avoiding direct positional interference between other parts of the cutting component 300 (such as the blade holder plate 320 of the cutting component 300 described below) and the part to be cut 510, making it easier to cut the part to be cut 510 and making the layout more reasonable.

[0063] In some specific embodiments of the present invention, such as Figure 1 , Figure 3 and Figure 5 As shown, the guide block 200 has a first side 210 and a second side 220. The first side 210 extends beyond the cutting surface 120. Specifically, the first side 210 and the second side 220 are the two opposite sides of the guide block 200 in the vertical direction. The first side 210 extending beyond the cutting surface 120 can be used to stop and position the cutting assembly 300 to limit the cutting assembly 300 in the vertical direction. The second side 220 is located below the cutting surface 120 and can be flush with the lower side of the main body plate 100. In this way, the contact area between the guide block 200 and the main body plate 100 can be large, which facilitates the connection and fixation between the guide block 200 and the main body plate 100.

[0064] In some specific embodiments of the present invention, such as Figures 1-3 , Figure 6 and Figure 9 As shown, the cutting assembly 300 includes a blade holder plate 320, a side plate 330, and a foot 340.

[0065] The blade holder plate 320 is located on the side of the main body plate 100 with the cutting surface 120, and the blade holder plate 320 is slidably in contact with the first side surface 210. The part to be cut 510 and the scraper 310 are located between the blade holder plate 320 and the cutting surface 120. One side of the side plate 330 is connected to the blade holder plate 320 and is located on the side of the guide block 200 facing away from the main body plate 100. The pad foot 340 is connected to the other side of the side plate 330 and is slidably in contact with the second side surface 220.

[0066] The tool holder plate 320 and the pad 340 can be parallel to the cutting surface 120, and the side plate 330 can be perpendicular to the cutting surface 120. One end of the side plate 330 can be bolted to the tool holder plate 320, and the pad 340 can be bolted to the other end of the side plate 330.

[0067] Therefore, the side plate 330 can connect the blade holder plate 320 and the pad 340 together. The space between the blade holder plate 320 and the pad 340 is used to clamp the guide block 200. Through the cooperation of the guide block 200, the blade holder plate 320 and the pad 340, the position of the cutting assembly 300 and the main body plate 100 in the vertical direction can be limited. On the one hand, it can prevent the blade holder plate 320 from being too close to the main body plate 100, so that the distance between the blade holder plate 320 and the main body plate 100 is sufficient to accommodate the scraper 310 and the part to be cut 510, and there is enough space for cutting operation. On the other hand, it can prevent the blade holder plate 320 from leaving the main body plate 100 or from being too far away from the main body plate 100, so that the scraper 310 can contact the part to be cut 510 and thus cut the part to be cut 510.

[0068] In addition, the side plate 330 can limit the cutting assembly 300 and the main body plate 100 in the left and right directions to prevent the relative positions of the cutting assembly 300 and the main body plate 100 from changing in the left and right directions, thereby fixing the position of the scraper 310 in the left and right directions, determining the relative position between the scraper 310 and the part to be cut 510, ensuring the consistency of multiple cuts, improving the cutting quality, and ensuring the yield rate.

[0069] In some specific embodiments of the present invention, such as Figures 4-7 and Figure 11 As shown, the cutting assembly 300 also includes a cutter head 350, which is located on the side of the cutter holder plate 320 facing the cutting surface 120. The cutter head 350 has a mounting notch 351 on the side facing away from the cutter holder plate 320, and the scraper 310 is mounted on the side wall of the mounting notch 351.

[0070] Specifically, the mounting notch 351 is located on the side of the cutter head 350 facing the workpiece 500. The cutter head 350 can fix the scraper 310, facilitating the positioning of the scraper 310. Furthermore, the cutter head 350 can support the scraper 310 when it cuts the part to be cut 510, thereby improving the structural strength of the scraper 310 and making it less prone to damage. Moreover, by providing the mounting notch 351, space is reserved for the installation of the scraper 310, and the scraper 310 is pre-positioned, facilitating the assembly between the scraper 310 and the cutter head 350. On the other hand, it avoids direct interference between the cutter head 350 and the part to be cut 510, facilitating cutting.

[0071] It should be noted that there may be a certain gap between the cutter head 350 and the main body plate 100, and between the scraper 310 and the main body plate 100. This gap can be set to be small, so that the scraper 310 can be separated from the cutter head 350 and the main body plate 100 respectively. When the scraper 310 moves to cut the part to be cut 510, there will be no friction between the main body plate 100 and the scraper 310, the movement of the scraper 310 will be easier, and there will be no wear between the scraper 310 and the main body plate 100.

[0072] Furthermore, such as Figures 11-12 As shown, the cutting assembly 300 also includes a handle 360 ​​and a connecting post 361. The handle 360 ​​is connected to the side of the tool holder plate 320 facing away from the cutting surface 120. In this way, the handle 360 ​​will not interfere with the cutting surface 120 in position. Moreover, the side of the tool holder plate 320 facing away from the cutting surface 120 has more space, which makes it easier to arrange the handle 360 ​​and also makes it easier for the operator to hold the handle 360, making the operation more convenient.

[0073] Furthermore, the tool holder 360 is connected to one end of the connecting post 361, which passes through the tool holder plate 320, and the other end of the connecting post 361 is connected to the cutter head 350. The tool holder plate 320 may have a connecting hole 322 through which the connecting post 361 passes. In other words, the tool holder 360, the cutter head 350, and the tool holder plate 320 are connected as a whole. The operator can push the tool holder 360 along the extension direction of the guide block 200, which will cause the cutter head 350 and the tool holder plate 320 to move together, thereby enabling the scraper 310 to move to cut the workpiece 500.

[0074] In some embodiments of the present invention, such as Figure 11 As shown, the cutting assembly 300 also includes a gas drive device (not shown in the figure). The handle 360 ​​is provided with an air passage 364. The connecting post 361 is rotatably connected to the handle 360. The pneumatic drive device is connected to the handle 360 ​​and communicates with the air passage 364. The gas drive device drives the gas to flow in the air passage 364 to drive the connecting post 361 to rotate the cutter head 350.

[0075] The air passage 364 is constructed in the connecting section 362. The air passage 364 passes through the outer peripheral surface of the end of the connecting section 362 that is connected to the gripping section 363, thereby communicating with the pneumatic drive device. The pneumatic drive device may include an air tube, which is connected to the handle 360 ​​and communicates with the air passage 364.

[0076] By setting up a gas drive device, on the one hand, the connecting column 361 can be driven to rotate the cutter head 350 to cut the part to be cut 510. On the other hand, the gas drive device guides the flow of gas in the air passage 364, without adding circuits to the cutting assembly 300, which improves the safety of the cutting assembly 300. Even if the operator holds the cutting assembly 300, there is no risk of electric shock.

[0077] Furthermore, such as Figure 11 As shown, the handle 360 ​​includes a connecting section 362 and a gripping section 363, so that the operator can grip the gripping section 363 of the handle 360 ​​to push the cutting assembly 300 to move, which facilitates operation.

[0078] Specifically, the connecting section 362 is connected to the side of the blade holder plate 320 facing away from the cutting surface 120, and the connecting section 362 is perpendicular to the cutting surface 120. The gripping section 363 is connected to the side of the connecting section 362 away from the blade holder plate 320, and the gripping section 363 extends along the sliding direction of the cutting assembly 300.

[0079] In this way, the operator can push and pull the handle 360 ​​along the extension direction of the grip section 363, making it more convenient to apply force. When applying force along the extension direction of the grip section 363, the left and right directions of the force are in the same plane as the central axis of the connecting section 362. There is no tendency for relative rotation between the grip section 363 and the connecting section 362, making it easier to push and pull the cutting assembly 300 and less likely to damage the handle 360.

[0080] In some specific embodiments of the present invention, such as Figure 3 and Figure 9 As shown, the dimension L1 of the foot 340 in the sliding direction of the cutting assembly 300 is greater than the dimension L2 of the guide block 200 in the sliding direction of the cutting assembly 300. In this way, when the cutting assembly 300 moves along its sliding direction, the foot 340 is less likely to disengage from the guide block 200, and the fit between the cutting assembly 300 and the guide block 200 is more stable.

[0081] For example, the size of the pad 340 in the sliding direction of the cutting assembly 300 can be larger than the size of the side plate 330 and the size of the tool holder plate 320. This can reduce the processing material of the side plate 330 and the tool holder plate 320. Moreover, one end of the pad 340 can extend out of the side plate 330. When the cutting assembly 300 is assembled with the guide block 200, one end of the pad 340 can engage with the guide block 200 first, thereby playing a role in assembly guidance, making assembly more convenient and faster.

[0082] In some specific embodiments of the present invention, such as Figure 3 , Figure 6 and Figure 13 As shown, the cutting assembly 300 also includes a first wear-resistant plate 370, which is located between the tool holder plate 320 and the guide block 200. The tool holder plate 320 has a first mounting groove 321 on its side facing the cutting surface 120, and the first wear-resistant plate 370 is installed within the first mounting groove 321. The first wear-resistant plate 370 has better wear resistance than the tool holder plate 320, resulting in less wear after repeated use and better durability. Even when the first wear-resistant plate 370 experiences significant wear, it can be directly replaced without replacing the tool holder plate 320, thus reducing maintenance costs.

[0083] By setting the first mounting groove 321, the first wear-resistant plate 370 can be fixed together with the tool holder plate 320, avoiding direct contact between the tool holder plate 320 and the guide block 200. This transforms the sliding friction between the tool holder plate 320 and the guide block 200 into sliding friction between the first wear-resistant plate 370 and the guide block 200, thereby reducing the wear of the tool holder plate 320.

[0084] Optionally, such as Figure 6 and Figure 13 As shown, the side of the first wear-resistant plate 370 facing the main body plate 100 is flush with the side of the tool holder plate 320 facing the main body plate 100. That is to say, the first wear-resistant plate 370 is completely installed into the first mounting groove 321, which prevents the first wear-resistant plate 370 from protruding from the tool holder plate 320. This makes the fixation of the first wear-resistant plate 370 more reliable and can reduce the overall volume of both the tool holder plate 320 and the first wear-resistant plate 370.

[0085] In addition, the width of the first wear-resistant plate 370 is not less than the width of the guide block 200.

[0086] For example, the width of the first wear-resistant plate 370 can be equal to the width of the guide block 200, or the width of the first wear-resistant plate 370 can be greater than the width of the guide block 200. In this way, the first wear-resistant plate 370 can completely block the side of the guide block 200 facing the blade holder plate 320, and can completely prevent the blade holder plate 320 from contacting the guide block 200 when the cutting assembly 300 moves, thus more effectively preventing wear between the blade holder plate 320 and the guide block 200.

[0087] In some specific embodiments of the present invention, such as Figure 3 , Figure 6 , Figure 9 As shown, the cutting assembly 300 also includes a second wear-resistant plate 380.

[0088] The second wear-resistant plate 380 is installed between the side plate 330 and the guide block 200. A second mounting groove 331 is provided on the side of the side plate 330 facing the cut surface 120. The second wear-resistant plate 380 is installed within the second mounting groove 331, and the side of the second wear-resistant plate 380 facing the guide block 200 protrudes beyond the side of the side plate 330 facing the guide block 200. The second wear-resistant plate 380 has better wear resistance than the side plate 330, resulting in less wear after repeated use and better durability. Even when the second wear-resistant plate 380 shows significant wear, it can be directly replaced without replacing the side plate 330, thus reducing maintenance costs.

[0089] By setting the second mounting groove 331, the second wear-resistant plate 380 can be fixed together with the side plate 330. Moreover, the side of the second wear-resistant plate 380 facing the guide block 200 protrudes from the side plate 330, avoiding direct contact between the side plate 330 and the guide block 200. This transforms the sliding friction between the side plate 330 and the guide block 200 into sliding friction between the second wear-resistant plate 380 and the guide block 200, thereby reducing the wear of the side plate 330.

[0090] It should be noted that the coefficient of friction of the first wear-resistant plate 370 and the second wear-resistant plate 380 can be less than the coefficient of friction of the tool holder plate 320 and the side plate 330. This results in less friction between the guide block 200 and the first wear-resistant plate 370 and the second wear-resistant plate 380, less resistance to movement of the cutting assembly 300, and easier movement and cutting.

[0091] In some specific embodiments of the present invention, such as Figure 6 As shown, the side of the pad 340 closest to the main body plate 100 is located between the two sides of the guide block 200 in the thickness direction, and the side of the pad 340 furthest from the main body plate 100 is located between the two sides of the side plate 330 in the thickness direction.

[0092] In other words, the side of the foot 340 closest to the main body plate 100 extends beyond the side plate 330 facing the guide block 200, but does not extend beyond the side of the guide block 200 facing the main body plate 100. This allows the foot 340 to both hold the side of the guide block 200 away from the tool holder plate 320, preventing the cutting assembly 300 from detaching upwards from the guide block 200, and prevent the end of the foot 340 closest to the main body plate 100 from interfering with the workpiece 500. Furthermore, the foot 340 and the side plate 330 have sufficient connection area to ensure reliability between them, while also reducing the size of the foot 340 and saving costs.

[0093] In some specific embodiments of the present invention, such as Figures 5-7 , Figure 10 As shown, the cutting device 1 also includes a cutting accuracy limiting component 400, which is installed on the cutting surface 120. The cutting accuracy limiting component 400 is used to fix the part to be cut 510 in a preset position. In other words, the cutting accuracy limiting component 400 is used to limit the relative position between the part to be cut 510 and the main body plate.

[0094] Therefore, the relative position of the part to be cut 510 and the scraper 310, as well as the size of the part to be cut 510 extending out of the cutting surface 120, can be adjusted by the cutting accuracy limiting component 400, thereby adjusting the size of the part to be cut 510 to be removed, so as to achieve the purpose of accurately removing the workpiece 500.

[0095] Furthermore, such as Figure 6 and Figure 8 As shown, the cutting precision limiting component 400 includes a pressure block 410. The cutting surface 120 is provided with a groove 140. A cutting through hole 110 is provided on the bottom wall of the groove 140. The pressure block 410 is installed in the groove 140 and is provided with a cutting through hole 411 communicating with the cutting through hole 110. The diameter of the cutting through hole 411 is smaller than the diameter of the cutting through hole 110. The part to be cut 510 extends into the cutting through hole 110 and the cutting through hole 411. For example, the outer peripheral surface of the part to be cut 510 contacts the inner peripheral wall of the cutting through hole 110. The pressure block 410 fixes the part to be cut 510 in a preset position in the radial direction of the part to be cut 510. In other words, the pressure block 410 fixes the relative position of the part to be cut 510 and the main body plate 100 in the radial direction of the part to be cut 510.

[0096] In this way, the groove 140 is used to accommodate the pressure block 410, which does not extend beyond the cutting surface 120, thereby determining the relative position of the cutting through hole 110 and the main body plate 100. Then, the part to be cut 510 is inserted into the cutting through hole 110. The inner peripheral wall of the cutting through hole 110 can restrict the relative position of the part to be cut 510 and the main body plate 100. Since the relative position of the cutting assembly 300 and the main body plate 100 is fixed, that is, the relative position of the scraper 310 and the part to be cut 510 is determined, the scraper 310 can cut the part to be cut 510 more accurately. In addition, the pressure block 410 can prevent the scraper 310 from causing the part to be cut 510 to shift when cutting it, making the positioning of the part to be cut 510 more stable and further improving the cutting accuracy.

[0097] In some specific embodiments of the present invention, such as Figure 10 , Figure 14 and Figure 15 As shown, the cutting accuracy limiting component 400 also includes a positioning plate 420, which is connected to the side of the pressure block 410 facing the cutting component 300. The positioning plate 420 and the pressure block 410 can be formed as one piece, and the positioning plate 420 is installed on the cutting surface 120. The positioning plate 420 fixes the part to be cut 510 in a preset position along the axial direction of the part to be cut 510.

[0098] The part to be cut 510 includes a limiting section 512 and a cutting section 511. The cutting section 511 is connected to the side of the limiting section 512 facing the cutting assembly 300. The cross-sectional area of ​​the limiting section 512 is larger than the cross-sectional area of ​​the cutting section 511. For example, the outer peripheral surface of the limiting section 512 contacts the inner peripheral wall of the cutting hole 411. The limiting section 512 abuts against the side of the positioning plate 420 facing away from the cutting assembly 300. The cutting section 511 extends beyond the cutting surface 120. The scraper 310 is used to cut the cutting section 511.

[0099] For example, there can be two positioning plates 420, which are arranged along the sliding direction of the cutting assembly 300 and are located on opposite sides of the cutting hole 411.

[0100] In this way, the cutting segment 511 of the part to be cut 510 will first extend into the cutting through hole 110 and the cutting through hole 411, and then extend beyond the cutting surface 120 between the two positioning plates 420 until the limiting segment 512 stops against the positioning plate 420. At this time, the cutting segment 511 is fully extended out of the cutting surface 120, and the cutting assembly 300 cuts the cutting segment 511. The limiting segment 512 is limited by the positioning plate 420 in the axial direction of the limiting segment 512 and by the pressure block 410 in the radial direction of the limiting segment 512. The processing accuracy is higher and the cutting precision yield is higher.

[0101] In some specific embodiments of the present invention, such asFigure 8 As shown, the main body plate 100 is provided with a clearance hole 130 for a structure that avoids the workpiece 500.

[0102] For example, the clearance holes 130 can be two located on opposite sides of the cutting through hole 110, and the plane passing through the central axis of the two clearance holes 130 is perpendicular to the sliding direction of the cutting assembly 300.

[0103] In this way, the clearance hole 130 can avoid other structures on the end of the workpiece 500 facing the main body plate 100, so that the workpiece 500 can fit against the lower side of the main body plate 100, and the part of the workpiece 500 that needs to be cut can better extend from the cutting surface 120 through the cutting through hole 110, so that the cutting assembly 300 can effectively cut the part to be cut 510.
