Description

Technical Field

[0001] The present invention relates to the field of cutting technology, and in particular to a cutting machine and a cutting system. Background Art

[0002] Cables wrapped in tubing often require either cutting or ring cutting, depending on the intended use. For example, cutting both the cable and tubing simultaneously, or simply cutting the tubing without damaging the cable, can be performed directly by a worker using a cutting machine. Ring cutting, however, can be accomplished with the aid of a specialized positioning device that works in conjunction with the cutting machine to precisely cut the tubing.

[0003] When using a cutting machine to cut both the cable and the casing, it is necessary to manually hold the cable and the casing, and then move them towards the cutting machine, which requires a larger space for easy operation. When using a cutting machine to cut the casing in a circular manner, in order to prevent damage to the cable, the operating accuracy is required to be higher. You can use a clamping device to clamp the casing, and then operate the clamping device to move the casing toward the cutting blade of the cutting machine, so that the operating space can be smaller during circular cutting. For ease of operation, the clamping device is usually movably connected to the cutting machine. If the position of the cutting machine for cutting is set between the connection point between the clamping device and the cutting machine and the circular cutting position, when cutting the cable and the casing, the stroke required for the clamping device to move will be very large, making it impossible to use in some small spaces.

Unless otherwise specified, "plurality" means two or more.

[0039] In this embodiment, when the cutting machine 01 is used to cut the wire tube assembly 02, the wire tube assembly 02 is manually moved closer to the cutting machine 01, which requires a large space for operation; when the cutting machine 01 is used to ring-cut the sleeve 21 of the wire tube assembly 02 but retain the cable 22, the movable unit 13 of the cutting machine 01 is usually used for auxiliary operation, and the space required for operation is small. When the cutting position is set between the connection between the movable unit 13 and the main unit 11 of the cutting machine 01 and the ring-cut position, if a cutting operation is required, since the space required for cutting is large, the stroke required for the movable unit 13 is also large, and it cannot be used in a small space, and the usage scenario is limited. Therefore, a cutting machine 01 is proposed. Figure 1 As shown, the cutting machine 01 may include a main unit 11 , a cutting unit 12 , and a movable unit 13 .

[0040] The cutting unit 12 may include a driving part 121 and a cutting part 122. The driving part 121 may be detachably connected to the main unit 11. The cutting part 122 may be drivingly connected to the driving part 121. The workpiece to be processed may be a wire tube assembly 02, and the wire tube assembly 02 may include a sleeve 21 and a cable 22. The driving part 121 may drive the cutting part 122 to rotate around the central axis of the cutting part 122, thereby performing a cutting operation or a ring cutting operation on the wire tube assembly 02. During the cutting operation of the cutting machine 01, the cutting part 122 may abut against the sleeve 21 and the cable 22 at the same time, thereby cutting the sleeve 21 and the cable 22 at the same time; during the ring cutting operation, the cutting part 122 abuts against the sleeve 21 and is spaced apart from the cable 22, thereby only cutting the sleeve 21 and not cutting the cable 22.

[0041] The movable unit 13 may include a first connecting portion 131 and a clamping module 132. One end of the first connecting portion 131 may be movably connected to the main unit 11, and the other end may be fixedly connected to the clamping module 132. The clamping module 132 may be used to secure the wire tube assembly 02. The wire tube assembly 02 and the clamping module 132 may rotate within a set angle around the movable connection between the first connecting portion 131 and the main unit 11, thereby moving the wire tube assembly 02 closer to or further away from the cutting portion 122, thereby achieving cutting of the wire tube assembly 02. Furthermore, the wire tube assembly 02 may also rotate within the clamping module 132 around its central axis, achieving a complete circumferential cut of the wire tube assembly 02.

[0042] Cutting machine 01 may include a cutting area and a circular cutting area. The circular cutting area may be located on the outer periphery of cutting portion 122. The pivotal connection between first connecting portion 131 and main unit 11 may be spaced apart from the circular cutting area. The circular cutting area may overlap with a portion of cutting portion 122, allowing conduit assembly 02 to abut against cutting portion 122 and cut conduit assembly 02. The cutting area may be spaced apart on the side of the circular cutting area away from the pivotal connection between first connecting portion 131 and main unit 11. When placing the wire tube assembly 02 in the cutting area to cut both the sleeve 21 and the cable 22, the precision requirement is relatively low. The worker holds the wire tube assembly 02 and moves it toward the cutting portion 122 in the cutting area. No other equipment is required to assist, which can reduce costs. However, a larger space is required for manual operation. When the sleeve 21 is circularly cut, higher precision is required to ensure the flatness of the incision and protect the cable 22. Therefore, the wire tube assembly 02 is clamped by the clamping module 132 during circular cutting. The worker can move the wire tube assembly 02 toward the cutting portion 122 in the circular cutting area by operating the movable unit 13 to circular cut the sleeve 21. In this way, the clamping module 132 can be moved within a smaller stroke to drive the wire tube assembly 02 to move toward or away from the cutting portion 122, thereby completing the circular cutting of the wire tube assembly 02. The cutting machine 01 can include a circular cutting state. The circular cutting state can include at least a portion of the clamping module 132 being located within the circular cutting area, the minimum distance from the central axis of the space enclosed by the clamping module 132 to the cutting portion 122 being a set distance, and the radius of the space enclosed by the clamping module 132 being greater than the set distance. In the circular cutting state, the conduit assembly 02 clamped by the clamping module 132 is within the circular cutting area, the cutting portion 122 abuts against the sleeve 21, and the cutting portion 122 is spaced apart from the cable 22, thereby circularly cutting the sleeve 21 and retaining the cable 22.

[0043] In this embodiment, if Figure 1 、 Figure 2 、 Figure 3As shown, the cutting machine 01 may further include an isolation unit 14. The isolation unit 14 may include an isolation module 141 and a support portion 142. The support portion 142 may be connected to the main unit 11, and the connection may be a fixed connection, which may improve the connection strength, or a detachable connection, which may facilitate the disassembly and assembly of the support portion 142. The isolation module 141 may be configured as a tubular body. The isolation module 141 may be movably connected to the support portion 142. Part of the isolation module 141 may be disposed in the annular cutting area. The isolation module 141 may be spaced apart from the cutting portion 122, and the space between the isolation modules may facilitate the sleeve 21 being sleeved on the outer peripheral side of the isolation module 141, and the cable 22 being disposed in the space surrounded by the inner peripheral wall of the isolation module 141. Part of the isolation module 141 may be disposed in the space surrounded by the clamping module 132. The isolation module 141 may move radially along the cutting portion 122. When the sleeve 21 is ring-cut, the sleeve 21 can be placed on the outer side of the isolation module 141, and the cable 22 can be set in the space surrounded by the inner wall of the isolation module 141. The sleeve 21, cable 22, and isolation module 141 move toward the cutting part 122 in the ring-cut area at the same time, which can prevent the cutting part 122 from causing damage to the cable 22 during the process of ring-cutting the sleeve 21.

[0044] In this embodiment, if Figure 3 As shown, the isolation module 141 may include an isolation tube 1411 and an avoidance portion 1412. The isolation tube 1411 may be connected to the avoidance portion 1412 along the axial direction of the isolation tube 1411, and the connection method may be a fixed connection or a detachable connection, which can be flexibly selected according to needs. The outer diameter of the avoidance portion 1412 may be smaller than the outer diameter of the isolation tube 1411. The avoidance portion 1412 may be arranged in the annular cutting area. The isolation tube 1411 may be movably connected to the support portion 142. The isolation tube 1411 may move radially along the cutting portion 122. When the sleeve 21 is annularly cut, the sleeve 21 may be respectively sleeved on the outer circumferential sides of the isolation tube 1411 and the avoidance portion 1412, and the cable 22 may be respectively arranged in the space surrounded by the inner circumferential wall of the isolation tube 1411 and the space surrounded by the inner circumferential wall of the avoidance portion 1412. When the sleeve 21 moves toward the cutting portion 122 within the annular cutting area, the isolation tube 1411 and the avoidance portion 1412 can also move with the sleeve 21 toward the cutting portion 122. When the cutting portion 122 cuts the sleeve 21, the small outer diameter of the avoidance portion 1412 can protect the cable 22 and prevent the avoidance portion 1412 from abutting the cutting portion 122, thereby extending the service life of the isolation module 141 and the cutting portion 122 and reducing costs.

[0045] In this embodiment, if Figure 1 、 Figure 2As shown, the isolation module 141 may include an isolation tube 1411 and a retaining ring 1413. The inner circumferential wall of the retaining ring 1413 may be connected to the outer circumferential wall of the isolation tube 1411, and the connection method may be a fixed connection or a detachable connection. The fixed connection method can improve the connection strength, and the detachable connection method allows the position of the retaining ring 1413 to be quickly changed, thereby improving work efficiency. The isolation tube 1411 may be movably connected to the support portion 142, and the isolation tube 1411 moves radially along the cutting portion 122. Part of the isolation tube 1411 may be arranged in the annular cutting area. The isolation tube 1411 may be spaced apart from the cutting portion 122, and the space between them may facilitate the sleeve 21 to be sleeved on the outer circumferential side of the isolation tube 1411, and the cable 22 to be arranged in the space surrounded by the inner circumferential wall of the isolation tube 1411. Part of the isolation tube 1411 may be arranged in the space surrounded by the clamping module 132. When circumcising the sleeve 21, the sleeve 21 can be placed around the outer circumference of the isolation tube 1411. One end of the sleeve 21 along its length can abut against the retaining ring 1413, while the cable 22 is within the space enclosed by the inner circumferential wall of the isolation tube 1411. The retaining ring 1413 can be used to limit the length of the cut sleeve 21. As the sleeve 21 moves toward the cutting portion 122 within the circumcision area, the isolation tube 1411 can move with the sleeve 21 toward the cutting portion 122. When the cutting portion 122 cuts the sleeve 21, the isolation tube 1411 protects the cable 22 from damage, and the circumcision of the sleeve 21 is completed.

[0046] In this embodiment, if Figure 2 、 Figure 3As shown, the clamping module 132 may include a first clamping portion 1321, a second clamping portion 1322, and a third clamping portion 1323. The first clamping portion 1321 may be fixedly connected to the first connecting portion 131, thereby increasing the strength of the clamping module 132. The second clamping portion 1322 may be movably connected to the first clamping portion 1321. The third clamping portion 1323 may be movably connected to the second clamping portion 1322. The first clamping portion 1321, the second clamping portion 1322, and the third clamping portion 1323 may be concentrically arranged. When it is necessary to perform a circumcision on the sleeve 21, the outer circumferential wall of the wire tube assembly 02 can be positioned within the space enclosed by the second clamping portion 1322. The second clamping portion 1322 and the third clamping portion 1323 are then rotated relative to each other along the central axis of the second clamping portion 1322, gradually reducing the inner diameter of the second clamping portion 1322 and allowing the inner circumferential wall of the second clamping portion 1322 to abut against the outer circumferential wall of the sleeve 21, securing the sleeve 21. The sleeve 21 can then be moved toward the cutting portion 122 near the circumcision area, allowing the sleeve 21 to abut against the cutting portion 122, thus completing the circumcision of the sleeve 21. During the circumcision process, the second clamping portion 1322, the third clamping portion 1323, and the sleeve 21 move synchronously. The second clamping portion 1322 can rotate relative to the first clamping portion 1321 about the central axis of the second clamping portion 1322, allowing any circumferential position of the sleeve 21 to abut against the cutting portion 122, completing the circumcision.

[0047] In other embodiments, when the second clamping portion 1322 and the third clamping portion 1323 are allowed to rotate relative to each other along the central axis of the second clamping portion 1322, a component movably connected to the first clamping portion 1321 can be used to abut against the second clamping portion 1322, thereby fixing the position of the second clamping portion 1322, thereby facilitating operation. The component movably connected to the first clamping portion 1321 can be a bolt, a pin, etc., which can be flexibly selected according to usage requirements.

[0048] In this embodiment, if Figure 2 As shown, the clamping module 132 may further include a second connecting portion 133. One end of the second connecting portion 133 may be fixedly connected to the end of the clamping module 132 away from the first connecting portion 131, and the other end may extend away from the first connecting portion 131. When a worker needs to perform a circumcision on the cannula 21 within the clamping module 132, the second connecting portion 133 may be manipulated to move the cannula 21 toward or away from the cutting portion 122, thereby keeping the worker's hands away from the cutting portion 122 for greater safety.

[0049] Cutting machine 01 can also enter a cutting state. This state can include the second connection portion 133 being positioned within a cutting area. The wire tube assembly 02 abuts against the cutting portion 122 within the cutting area. When the wire tube assembly 02 is cut, the second connection portion 133 within the cutting area can block metal debris generated during cutting, reducing contact between metal debris and workers and improving safety.

[0050] In this embodiment, if Figure 2 、 Figure 4 As shown, the cutting machine 01 may further include an adjustment module 15. The adjustment module 15 includes an adjustable seat 151 and a first limiting rod 153. The adjustment seat 151 may be connected to the main unit 11 in either a detachable or fixed manner. The first limiting rod 153 may be detachably connected to the adjustment seat 151. This detachable connection facilitates maintenance and quick assembly and disassembly.

[0051] like Figure 5 As shown, the movable unit 13 may further include a limiting module 135. The limiting module 135 may include a third connecting portion 1351 and a limiting groove 1352. One end of the third connecting portion 1351 may be connected to the end of the second connecting portion 133 away from the first connecting portion 131, and the connection method may be a detachable connection or a fixed connection. The limiting groove 1352 may be recessed from one side of the third connecting portion 1351 toward the other side, for cooperating with the first limiting rod 153. The length direction of the limiting groove 1352 may coincide with the circumferential direction of the cutting portion 122, so that the limiting groove 1352 can move within the axial symmetry plane of the cutting portion 122 under the restriction of the first limiting rod 153.

[0052] The circumferential cutting state may further include the first limiting rod 153 being disposed in the space surrounded by the limiting groove 1352 and being slidably connected to the limiting groove 1352. When the sleeve 21 in the clamping module 132 needs to be circumferentially cut, the limiting groove 1352, restricted by the first limiting rod 153, can only move within the axial symmetric plane of the cutting portion 122, thereby limiting the movement direction of the sleeve 21 and ensuring the smoothness of the cut after circumferential cutting of the sleeve 21.

[0053] In other embodiments, the movable unit 13 may further include an elastic portion. The elastic portion may be detachably connected to the main unit 11 and to the first connecting portion 131. The elastic force of the elastic portion may allow the first connecting portion 131 to move away from the cutting portion 122, thereby facilitating the cutting of the wire tube assembly 02. The limiting module 135 may further include a second limiting rod 1353. The second limiting rod 1353 may be detachably connected to an end of the third connecting portion 1351 away from the first connecting portion 131. When the third connecting portion 1351 moves in cooperation with the first limiting rod 153 and the limiting groove 1352, the second limiting rod 1353 may prevent the second connecting portion 133 from leaving the cutting area, allowing the second connecting portion 133 to continue to block metal debris generated by cutting from splashing directly toward the worker when the pipe cutting assembly is cut.

[0054] In this embodiment, if Figure 4 As shown, the movable unit 13 may further include a pressing portion 134. The pressing portion 134 may be connected to the second connecting portion 133, and the connection may be detachable or fixed. When a worker operates the movable unit 13, the pressing portion 134 may be operated to move the movable unit 13. The position where the main unit 11 and the movable unit 13 are movably connected is farther from the pressing portion 134, which makes operation more labor-saving.

[0055] The adjustment module 15 may further include an adjustment rod 152. The adjustment rod 152 may be movably connected to the adjustment seat 151.

[0056] The circumferential cutting state may further include the pressing portion 134 abutting against the adjusting rod 152. When the sleeve 21 needs to be circumcised, the distance that the cutting portion 122 enters the space enclosed by the sleeve 21 can be calculated based on the distance between the sleeve 21 and the cable 22, and then the adjusting rod 152 is moved to a height that matches the distance that the cutting portion 122 enters the space enclosed by the sleeve 21. When the pressing portion 134 abuts against the adjusting rod 152, the sleeve 21 in the clamping module 132 cannot move further toward the cutting portion 122, thereby preventing damage to the cable 22 while ensuring that the circumferential cutting of the sleeve 21 is completed.

[0057] In this embodiment, if Figure 6 As shown, the main unit 11 may include a main module 111 and a fixing module 112. The fixing module 112 may include a protective cover 1121, a first groove 1122, and a second groove 1123.
