[0016] The cutting equipment also includes a first baffle and a second baffle. The first baffle is located at one end of the turntable and is used to stop one end of the workpiece to be processed.

[0052] like Figure 2 As shown, an embodiment of the present application provides a cutting device 100, which relates to the field of parts processing technology and is mainly used for cutting a workpiece 200 to be processed, such as a cylinder 210, a sphere and other rotating parts.

[0053] Combine Figure 1 and Figure 10As shown, the cutting device 100 mainly includes: a frame 110, a rotary disk 120, a friction member 130 and a cutting member 140.

[0054] The frame 110 is provided with a feed section 1123 and a discharge section 1124. The feed section 1123 is used to place the workpiece 200 to be processed, that is, the feed section 1123 can store the workpiece 200 to be processed. The discharge section 1124 is used to output the finished product 300 after cutting. The turntable 120 is rotatably mounted on the frame 110 and is located between the feed section 1123 and the discharge section 1124, so that the turntable 120 can rotate relative to the frame 110 about its rotation axis between the feed section 1123 and the discharge section 1124.

[0055] A plurality of positioning grooves 121 are provided along the circumference of the turntable 120 . Each positioning groove 121 can accommodate a portion of a workpiece 200 to be processed. That is, a portion of the workpiece 200 to be processed can be accommodated by the positioning groove 121 , while the other portion cannot.

[0056] The friction member 130 is arranged close to the circumference of the turntable 120, and forms a limiting space 191 between it and part of the circumference of the turntable 120. The plurality of positioning grooves 121 are at least partially located in the limiting space 191, that is, the plurality of positioning grooves 121 can all be located in the limiting space 191. Of course, only a part of the positioning grooves 121 can be located in the limiting space 191.

[0057] The cutting member 140 is disposed at an end of the rotating disk 120, for example, at one end of the rotating disk 120, or at the other end of the rotating disk 120. Of course, the cutting member 140 can also be disposed at both ends of the rotating disk 120. At the same time, the cutting member 140 is located on the side of the limiting space 191 away from the friction member 130.

[0058] In this way, when the turntable 120 rotates around its rotation axis, the workpiece 200 to be processed falls from the feed part 1123 into the positioning groove 121, and revolves around the rotation axis of the turntable 120 driven by the turntable 120, and at the same time rotates under the action of the friction force applied by the friction part 130, so that the cutting part 140 cuts the part of the workpiece 200 to be processed that protrudes from the positioning groove 121 along the direction of the rotation axis of the turntable 120, and the finished product 300 after cutting falls into the discharge part 1124.

[0059] It should be noted that the above-mentioned cutting member 140 is arranged at the end of the turntable 120, which means that the cutting member 140 is at the end position of the turntable 120. The cutting member 140 can be connected to the frame 110 and is located on the side of the limiting space 191 away from the friction member 130. Of course, the cutting member 140 can also be connected to the end of the turntable 120 and is located on the side of the limiting space 191 away from the friction member 130, and both can cut the protruding parts of the workpiece 200 to be processed.

[0060] Existing cutting equipment can only process one workpiece at a time, and after processing is completed, the spindle needs to be interrupted and the spindle's clamping of the workpiece needs to be released before the next workpiece can be replaced. Therefore, the operation process is relatively complicated and the processing efficiency is low.

[0061] Exemplarily, when using the cutting equipment 100 provided in this embodiment, the user places the workpiece 200 to be processed in the feed part 1123. One workpiece 200 to be processed or multiple workpieces 200 to be processed can be placed. The turntable 120 rotates so that the workpiece 200 to be processed falls from the feed part 1123 into the positioning groove 121 of the turntable 120. As the turntable 120 rotates, the workpiece 200 to be processed revolves around the rotation axis of the turntable 120 and enters the limited space 191, and rotates under the friction force of the friction part 130. At this time, the cutting part 140 contacts the part of the workpiece 200 to be processed that protrudes from the positioning groove 121 along the rotation axis direction of the turntable 120, and cuts the above-mentioned protruding part of the cutting part 140. After cutting, the finished product 300 falls into the discharge part 1124 and is output from the discharge part 1124.

[0062] Thus, compared to the existing method of cutting by clamping the workpiece with a spindle, the cutting device 100 provided in this embodiment, due to the provision of the friction member 130 and the turntable 120, enables the workpiece 200 to be simultaneously in a state of revolution and rotation, thereby enabling the cutting member 140 to cut the workpiece 200. Therefore, there is no need to stop the machine to replace the workpiece 200, and continuous cutting can be achieved, thereby achieving higher processing efficiency. Furthermore, during use, the workpiece 200 only needs to be placed in the feed portion 1123, without the need to clamp the workpiece 200, making operation more convenient.

[0063] Combine Figure 10 、 Figure 11 and Figure 13 As shown, in one embodiment, the cutting piece 140 is a cutter disc having a plurality of cutter grains 141 on its circumference. The cutter grains 141 are used to cut the portion of the workpiece 200 protruding from the positioning groove 121 along the direction of the rotation axis of the turntable 120. The cutter disc is rotatably arranged at the end of the turntable 120. The rotation axis of the cutter disc is offset relative to the rotation axis of the turntable 120 in the direction of the limit space 191, and the rotation direction b of the cutter disc is opposite to the rotation direction a of the turntable 120.

[0064] For example, the cutter disc may be rotatably connected to the end of the turntable 120 , and of course, may also be rotatably connected to the frame 110 .

[0065] In this embodiment, since a cutter disc is provided, the workpiece 200 is cut by the cutting particles 141 on the rotating cutter disc while in orbit and rotation, thereby greatly shortening the cutting time of the workpiece 200 and further improving the efficiency of the cutting process.

[0066] Combine Figure 5 、 Figure 13 and Figure 14 As shown, in a specific embodiment, the workpiece 200 to be processed is a cylinder 210, the positioning groove 121 is an arc-shaped groove adapted to the outer shape of the cylinder 210, and the knife grain 141 has a first cutting portion 1411 and a second cutting portion 1412, and the first cutting portion 1411 and the second cutting portion 1412 are arranged at intervals along the rotation axis direction of the turntable 120.

[0067] In this embodiment, the first cutting portion 1411 is used to cut the end of the cylinder 210 to chamfer the end of the cylinder 210 to form a chamfered portion 310. At the same time, the second cutting portion 1412 is used to cut the circumference of the cylinder 210 to radially groove the cylinder 210 to form an annular radial groove 320.

[0068] Existing cutting equipment requires two sets of drive structures to chamfer and radially groove a cylinder, and two sets of tools are used to feed the cylinder axially and radially respectively, resulting in a more complex overall structure of the cutting equipment and a larger space occupation.

[0069] However, in this embodiment, the first cutting portion 1411 and the second cutting portion 1412 are integrated into the cutter head. The rotation of the cutter head allows simultaneous cutting of the ends and the circumference of the cylindrical body 210. This results in a more compact structure, which helps reduce the space occupied by the cutting apparatus 100 and facilitates a more compact design. Furthermore, during the machining process, the first cutting portion 1411 and the second cutting portion 1412 rotate with the cutter head, significantly reducing cutting time and increasing cutting efficiency.

[0070] In another specific embodiment, the workpiece 200 to be processed is a sphere, the positioning groove 121 is a spherical groove adapted to the shape of the sphere, and the blade 141 also has a first cutting portion 1411 and a second cutting portion 1412, which are used to cut the end and middle areas of the sphere respectively, thereby realizing cutting processing of the spherical parts.

[0071] Of course, the workpiece 200 to be machined can also be other rotating parts, such as a frustum or cone. Accordingly, the positioning groove 121 is an arc-shaped groove with a gradually changing cross-sectional area. Therefore, any part suitable for rotation and revolution within the positioning groove 121 is applicable to the cutter head and turntable 120 structure of this embodiment. Specific types of workpieces 200 to be machined are not exhaustively listed here.

[0072] In another embodiment, the cutting element 140 can also be a separate blade pellet 141, which is fixed to the frame 110 and positioned near the end of the turntable 120 and the limiting space 191. During the machining process, the position of the blade pellet 141 remains fixed, and the workpiece 200 to be machined can be cut by the blade pellet 141 even when it is in both orbital and rotational states.

[0073] Combine Figure 2 、 Figure 10 and Figure 11 As shown, in one embodiment, the friction member 130 is an annular acceleration belt 131, and the cutting equipment 100 also includes a first driving mechanism 150, the first driving mechanism 150 includes a driving assembly 151 and a support shaft assembly 152, and the annular acceleration belt 131 is arranged around the support shaft assembly 152, and a portion of the belt surface of the annular acceleration belt 131 is arranged close to the circumference of the turntable 120 to define a limit space 191.

[0074] Among them, the driving component 151 and the support shaft component 152 are respectively arranged on the frame 110, and the driving component 151 is connected to the support shaft component 152 to drive the annular acceleration belt 131 to rotate through the support shaft component 152. The rotation direction c of the annular acceleration belt 131 is the same as the rotation direction a of the turntable 120.

[0075] In this embodiment, since an annular acceleration belt 131 is provided, the annular acceleration belt 131 can rotate in the same direction as the rotation direction a of the turntable 120 under the drive of the support shaft assembly 152, thereby increasing the rotation speed of the workpiece 200 to be processed. Therefore, under the high-speed rotation of the workpiece 200 to be processed, the cutting part 140 can cut the workpiece 200 to be processed faster, greatly improving the processing efficiency of the cutting equipment 100 on the workpiece 200 to be processed.

[0076] Combine Figure 2 、 Figure 4 and Figure 11 As shown, further, the driving assembly 151 may include a first driver 1511 provided on the frame 110 , such as a motor or a driving motor, and the support shaft assembly 152 includes a first support shaft 1521 , a second support shaft 1522 and a third support shaft 1523 .

[0077] Among them, the first support shaft 1521 and the second support shaft 1522 are arranged along the circumference of the turntable 120, the third support shaft 1523 is arranged away from the limiting space 191, the annular acceleration belt 131 is wound around the first support shaft 1521, the second support shaft 1522 and the third support shaft 1523, and the first driver 1511 is connected to one end of the second support shaft 1522.

[0078] In this way, the first driver 1511 can drive the second supporting shaft 1522 to rotate around its axis, thereby driving the annular acceleration belt 131 to rotate, and realizing the rotation of the workpiece 200 under the friction force of the annular acceleration belt 131. Of course, the driving assembly 151 may also include a second driver 1512, the second driver 1512 is connected to the other end of the second supporting shaft 1522, thereby synchronously driving the second supporting shaft 1522 to rotate with the first driver 1511, or the second driver 1512 is connected to one end of the first supporting shaft 1521, thereby driving the annular acceleration belt 131 to rotate through the synchronous rotation of the first supporting shaft 1521 and the second supporting shaft 1522.

[0079] like Figure 4 As shown, further, the first driving mechanism 150 also includes a support frame, a threaded fastener and a bearing seat 153. The support frame is connected to the frame 110, and the first support shaft 1521, the second support shaft 1522 and the third support shaft 1523 are respectively rotatably arranged on the support frame through the bearing seat 153.

[0080] Among them, the third support shaft 1523 is a tensioning shaft, a waist hole 1531 is opened on the bearing seat 153 which is rotatably connected to the tensioning shaft, a connecting hole 1931 is opened on the support frame, and the screw of the threaded fastener is passed through the waist hole 1531 and the connecting hole 1931, and is threadedly connected to the hole wall of the connecting hole 1931.

[0081] It can be understood that the setting of the waist hole 1531 and the connecting hole 1931 facilitates the adjustment of the distance between the tensioning shaft and the first support shaft 1521 or the second support shaft 1522, thereby adjusting the tension of the annular acceleration belt 131 to adapt to different rotational speeds, reduce the probability of the annular acceleration belt 131 slipping, and improve stability.

[0082] Of course, in the above embodiment, the friction member 130 may also be a friction plate, with one side of the friction plate disposed adjacent to the circumference of the turntable 120. This friction plate can also drive the workpiece 200 to rotate within the positioning groove 121 through friction. Furthermore, to increase friction, the friction plate can be made of an elastic material such as silicone, rubber, or spandex.

[0083] like Figure 6 and Figure 9 As shown, in one embodiment, the frame 110 includes a first bracket 112 and a base plate 111, the first bracket 112 is arranged on the base plate 111, the cutting equipment 100 also includes a second driving mechanism 160, the second driving mechanism 160 includes a first driving member 161 and a first transmission assembly 162, the turntable 120 is rotatably arranged on the first bracket 112, the first transmission assembly 162 is arranged on the first bracket 112, and is respectively connected to the turntable 120 and the first driving member 161.

[0084] The first driving member 161 can drive the turntable 120 to rotate around its rotation axis through the first transmission assembly 162 , thereby causing the workpiece 200 to revolve around the rotation axis of the turntable 120 , thereby meeting the need for high-speed processing.

[0085] For example, the first driving member 161 may be an electric motor or a drive motor, and the first transmission assembly 162 may include a first bearing member 1621 and a first transmission shaft 1622. The first bearing member 1621 is embedded in the first bracket 112, and the first rotating shaft passes through the first bearing member 1621 and is respectively connected to the first driving member 161 and the turntable 120. Thus, the arrangement of the first bearing member 1621 and the first transmission shaft 1622 enables the turntable 120 to rotate at high speed, thereby meeting the requirements of high-speed processing.

[0086] like Figure 8 As shown, when the cutting member 140 is a cutter disc, the frame 110 also includes a second bracket 113 arranged on the base plate 111, and the cutting device 100 also includes a third driving mechanism 170. The second driving mechanism 160 is arranged on the second bracket 113 and is connected to the cutter disc for driving the cutter disc to rotate around its rotation axis.

[0087] Specifically, the third driving mechanism 170 includes a second driving member 171 and a second transmission assembly 172 . The second transmission assembly 172 includes a second bearing member 1721 and a second transmission shaft 1722 .

[0088] Among them, the second bearing member 1721 is embedded in the second bracket 113, and the second transmission shaft 1722 connected to the second driving member 171 is passed through the second bearing member 1721 and connected to the cutter disc, so that the cutter disc is driven to rotate around its rotation axis under the drive of the second driving member 171, so that the knife particles 141 on the cutter disc can quickly cut the workpiece 200 to be processed, meeting the needs of high-speed processing.

[0089] Continue reading Figure 8 Furthermore, the second bracket 113 is slidingly connected to the base plate 111, and the cutting equipment 100 also includes a feed adjustment mechanism 195, which includes a rotating handle 1951, a base 1952 and a screw rod 1953. The base 1952 is arranged on the base plate 111 and has a U-shaped groove 19521. The rotating handle 1951 is hinged in the U-shaped groove 19521. One end of the screw rod 1953 is connected to the rotating handle 1951, and the other end is passed through the threaded hole of the second bracket 113.

[0090] When using the feed adjustment mechanism 195, the user rotates the handle 1951 to drive the second bracket 113 to slide along the base plate 111 through the screw rod 1953, so as to adjust the distance between the knife grain 141 on the cutter disc and the limit space 191, thereby realizing the adjustment of the feed amount of the knife grain 141, that is, the cutting amount of the knife grain 141 on the workpiece 200 to meet different processing requirements.

[0091] Combine Figure 6 、 Figure 7 and Figure 12 As shown, in one embodiment, the cutting device 100 further includes a guard plate 192 , which is located between the feed portion 1123 and the friction member 130 , and is arranged circumferentially close to the turntable 120 , and the side of the guard plate 192 close to the turntable 120 is an arc-shaped limiting surface 1921 .

[0092] In this embodiment, during the rotation of the turntable 120, the arc-shaped limiting surface 1921 can contact the workpiece 200 to limit the workpiece 200 from slipping out of the positioning groove 121 in the direction a away from the turntable 120, so that the workpiece 200 can smoothly follow the turntable 120 into the limiting space 191.

[0093] It can be seen that the provision of the guard plate 192 effectively reduces the risk of the workpiece 200 slipping radially along the turntable 120, improves the stability and smoothness of the processing process, and at the same time, increases the safety of the cutting equipment 100 and avoids personal injury.

[0094] Combine Figure 2 、 Figure 3 ,as well as Figure 6 and Figure 7 As shown, in order to further improve stability and safety, the cutting equipment 100 may also include a first baffle 193 and a second baffle 194. The first baffle 193 is located at one end of the turntable 120, and is used to stop one end of the workpiece 200 to be processed. The second baffle 194 is located at the other end of the turntable 120, and is used to stop one end of the workpiece 200 to be processed away from the first baffle 193. The friction member 130 is located between the first baffle 193 and the second baffle 194.

[0095] In this embodiment, the first and second baffles 193 and 194 restrict the workpiece 200 from moving from the positioning slot 121 along the rotation axis of the turntable 120. This effectively positions the workpiece 200, allowing the cutting element 140 to perform cutting operations more accurately, thereby improving the yield rate of the finished product. Furthermore, when there are multiple workpieces 200 to be processed, the first and second baffles 193 and 194 can align them, thereby preventing variations in the finished product 300 after cutting.

[0096] In addition, the friction member 130 is located between the first baffle 193 and the second baffle 194 , which improves the compactness of the structure, reduces the space occupied by the friction member 130 , and is conducive to the miniaturized design of the cutting device 100 .

[0097] Combine Figure 4 and Figure 7 As shown, it should be noted that the first baffle 193 and the second baffle 194 can also serve as mounting carriers of the support shaft assembly 152 in the aforementioned embodiment.

[0098] Specifically, an extension shaft 1121 is provided on the frame 110, and the extension shaft 1121 is connected to one end of the first baffle 193. The first driver 1511 is connected to the frame 110 and is connected to the end of the first baffle 193 away from the extension shaft 1121. The first baffle 193 and the second baffle 194 are connected by multiple support shafts 1122. The first support shaft 1521, the second support shaft 1522 and the tensioning shaft are all connected between the first baffle 193 and the second baffle 194 through the bearing seat 153. At the same time, the first baffle 193 and the second baffle 194 are both provided with connecting holes 1931, and the bearing seat 153 on the tensioning shaft is provided with a waist hole 1531.

[0099] It can be understood that by using the first baffle 193 and the second baffle 194 as support frames for the support shaft assembly 152, the first baffle 193 and the second baffle 194 can not only limit the workpiece 200, but also serve as an installation carrier for the support shaft assembly 152, thereby reducing the use of the support structure, improving the compactness of the structure, and facilitating the miniaturization design of the cutting equipment 100.

[0100] like Figure 10 As shown, in one embodiment, a plurality of positioning grooves 121 are spaced apart, and a stopper 122 is provided between two adjacent positioning grooves 121. Thus, when the turntable 120 rotates about its rotation axis, the stopper 122 can abut against the workpiece 200 to prevent the workpiece 200 from slipping out of the positioning groove 121 in a direction opposite to the rotation direction a of the turntable 120, that is, preventing the workpiece 200 from slipping out in the radial or oblique direction of the turntable 120, thereby enabling the cutting element 140 to accurately cut the workpiece 200, thereby improving the qualified rate of the finished product 300 and the safety of the cutting device 100.

[0101] like Figures 11 to 13 As shown, further, the stopper 122 is a wedge block 1221 , and the side of the wedge block 1221 away from the turntable 120 is an inclined surface 12211 , and the inclined direction of the inclined surface 12211 is opposite to the rotation direction a of the turntable 120 .

[0102] In this embodiment, the wedge block 1221 is provided to effectively stop the workpiece 200 to be processed, reducing the probability of the workpiece 200 slipping from the positioning groove 121, and effectively improving the qualified rate of the finished product 300 and the safety of the cutting equipment 100.

[0103] like Figure 12 As shown, further, the angle α formed between the inclined surface 12211 and the circumference of the turntable 120 satisfies the relationship: 10°≤α≤20°.

[0104] Exemplarily, the angle α formed between the inclined surface 12211 and the circumference of the turntable 120 can be set to 10°, 11°, 12°, 14°, 15°, 15.5°, 16°, 16.5°, 18°, 19°, 20°, etc., and can be set specifically according to design requirements.

[0105] In this embodiment, by providing a wedge block 1221 satisfying the aforementioned relationship between two adjacent positioning grooves 121, wedge block 1221 has a sufficient inclination, thereby more effectively stopping workpiece 200 and reducing the probability of workpiece 200 slipping from positioning groove 121, thereby effectively improving the yield rate of finished products and the safety of cutting device 100. Furthermore, in this embodiment, after verification by the designers, the angle α formed between inclined surface 12211 and the circumference of turntable 120 is preferably 16°.

[0106] In one embodiment, the workpiece 200 is loosely matched with the positioning groove 121 , so that the workpiece 200 can smoothly rotate in the positioning groove 121 , thereby being able to adapt to high-speed working conditions and effectively improving the processing efficiency of the workpiece 200 .

[0107] Combine Figure 2 and Figure 3 As shown, in one embodiment, the feed portion 1123 is a vertically arranged feed hopper, and the feed hopper is provided with a lateral opening 11231 running through it in the vertical direction. The cutting equipment 100 also includes a cut-off mechanism 180, and the cut-off mechanism 180 includes a third driver 181, a connecting shaft 182 and a cut-off component 183. The third driver 181 is arranged on the frame 110 and is connected to the cut-off component 183 through the connecting shaft 182. The cut-off component 183 is arranged at the lateral opening 11231.

[0108] When the cutoff mechanism 180 is in use, the third driver 181 drives the connecting shaft 182 to rotate, thereby causing the cutoff component 183 to rotate about the axis of the connecting shaft 182. When the cutoff component 183 rotates to a first preset state, the cutoff component 183 can prevent the workpiece 200 in the feed hopper from falling into the positioning groove 121 of the turntable 120. When the cutoff component 183 rotates to a second preset state, the workpiece 200 in the feed hopper can smoothly fall into the positioning groove 121 and enter the limited space 191 for cutting as the turntable 120 rotates.

[0109] It can be seen from this that, by setting the cut-off mechanism 180 , the degree of automation of the cutting device 100 is improved, the complexity of the manual feeding operation is reduced, and the feeding is more convenient.

[0110] In one embodiment, the discharge portion 1124 is a tilted discharge hopper, which facilitates the collection and output of the finished product 300 after cutting. In another embodiment, the discharge portion 1124 can also be a horizontal conveyor belt with baffles provided on both sides of the conveyor belt perpendicular to the conveying direction, which can also collect and output the finished product 300 after cutting.

[0111] In summary, the embodiments of the present application provide a cutting device 100. During use, a workpiece 200 is fed through a feed hopper into the positioning slot 121 of a turntable 120, where it forms a clearance fit with the positioning slot 121. Driven by the turntable 120, the workpiece 200 undergoes high-speed orbital rotation. Driven by the annular acceleration belt 131, the workpiece 200 rotates at high speed along the walls of the positioning slot 121, enabling the high-speed rotating cutterhead to continuously cut the workpiece 200, achieving stepless cutting feed. Tests have shown that the cutting device 100 can achieve a processing speed of over 200 pieces per minute, 20-30 pieces per minute more than conventional turning operations.

[0112] like Figure 15 As shown, an embodiment of the present application further provides a cutting method, including steps S410 to S440.

[0113] S410 , the workpiece 200 to be processed falls from the feeding portion 1123 into the positioning groove 121 of the turntable 120 .

[0114] S420 , the turntable 120 drives the workpiece 200 to revolve, and at the same time, the friction member 130 drives the workpiece 200 to rotate.

[0115] S430 , the cutting piece 140 cuts the portion of the workpiece 200 protruding from the positioning groove 121 along the rotation axis direction of the turntable 120 .

[0116] S440, the discharging unit 1124 outputs the finished product 300 after cutting.

[0117] It can be understood that the cutting method provided in this embodiment has a high processing efficiency because the cutting piece 140 can cut the workpiece 200 to be processed in rotation and revolution to achieve continuous cutting processing.

[0118] Furthermore, the friction part 130 is an annular acceleration belt 131, and the cutting part 140 is a cutter disc. The rotation direction c of the annular acceleration belt 131 is the same as the rotation direction a of the turntable 120, and the rotation direction b of the cutter disc is opposite to the rotation direction a of the turntable 120, thereby realizing high-speed and continuous cutting processing and further improving processing efficiency.
