Description

Technical Field

[0001] This application relates to the field of cutting equipment technology, and in particular to a material auxiliary fixing device and cutting equipment for cutting processing. Background Technology

[0002] A cutting device is a processing equipment for shaping and cutting blanks. For example, it cuts blanks according to preset material dimensions and contour paths to produce materials with corresponding dimensions and contours. The cutting device includes a drive motor, a transmission mechanism, and a cutting tool. The drive motor drives the cutting tool through the transmission mechanism, and the cutting tool reciprocates to cut the blank to its contour.

[0003] During the cutting process, the cutting device is equipped with a fixing device to support, limit, and clamp the material to maintain a stable processing posture. However, during the loading and unloading process of the cutting device, the fixing device needs to move relative to the cutting tool to switch materials. This movement process can easily cause the fixing device to exert thrust on the material in other directions, leading to incorrect material deviation, which in turn affects the processing positioning accuracy and the quality of the finished product. Summary of the Invention

[0004] The purpose of this application is to provide a material auxiliary fixing device and cutting equipment for cutting processes, thereby solving the aforementioned technical problems existing in the prior art.

[0005] In a first aspect, embodiments of this application provide a material auxiliary fixing device for cutting processing. The material auxiliary fixing device includes a swing arm, a housing, and a driving member. The driving member is mounted on the housing and includes a driving shaft. The swing arm is rotatably connected to the driving shaft. The driving shaft is used to drive the swing arm to reciprocate along a first direction, so that the swing arm switches between a first position and a second position. The housing has a constraint portion, the swing arm has a constraint engagement portion that cooperates with the constraint portion, and the swing arm has a support portion. When the swing arm is in the first position, the support portion is used to support and fix the material along the first direction. When the driving shaft drives the swing arm from the first position to the second position, the constraint portion guides the constraint engagement portion so that the support portion moves sequentially along a first path and a second path. The first path extends along the first direction, and at least a portion of the extension direction of the second path intersects the first direction.

[0006] Secondly, embodiments of this application provide a cutting device, which includes a material auxiliary fixing device as described in the first aspect, and further includes a cutting assembly. The cutting assembly and the support cooperate with each other to fix the material.

[0007] The technical solution adopted in this application can achieve the following beneficial effects: the swing arm is rotatably connected to the drive shaft, and the drive shaft is used to drive the swing arm to reciprocate along a first direction, so that the swing arm switches between a first position and a second position. The first position and the second position are two different positions of the swing arm. Specifically, the drive component can be a linear motor, and the drive component has a drive shaft, which can drive the swing arm to move linearly along the first direction, so that the swing arm switches from one of the first position and the second position to the other.

[0008] Compared to existing technologies, this application guides the constraint mating part through a constraint part, causing the support part to move sequentially along a first path and a second path. The first path extends along a first direction, and the second path at least partially intersects the first direction. When the first constraint part moves along the first path, it drives the support part to move away from the material and release the support limit. When the first constraint part moves along the second path, it changes its direction of movement under guidance and drives the support part to complete the avoidance action. This arrangement, through the orderly movement of the support part releasing the support limit and disengaging from mutual contact before avoiding the material, effectively avoids unexpected thrust on the material during the movement of the support part. Furthermore, the material auxiliary fixing device only requires a single drive source to achieve movement along both paths, eliminating the need for additional drive components. This simplifies the structure of the material auxiliary fixing device while effectively ensuring stable material positioning, improving processing accuracy and finished product quality.

[0012] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.

It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0014] This application provides a material auxiliary fixing device 100 for cutting processing. Please refer to [link to relevant documentation]. Figure 1 and Figure 2 The material auxiliary fixing device 100 includes a swing arm 110, a housing 120 and a drive component 130. The drive component 130 is installed in the housing 120 and the swing arm 110 is connected to the drive component 130.

[0015] In the embodiments of this application, please refer to Figure 2 The drive component 130 is mounted on the housing 120 and includes a drive shaft 131. The swing arm 110 is rotatably connected to the drive shaft 131, which drives the swing arm 110 to move along a first direction L1, allowing the swing arm 110 to switch between a first position and a second position. The drive component 130 can be an electric actuator or a linear motor, etc. The first position and the second position are two different positions on the movement path of the swing arm 110, which is not limited in this application. For example, the drive component 130 has a drive shaft 131, and the first direction L1 can be vertical. The drive shaft 131 can drive the swing arm 110 to reciprocate along the vertical direction, that is, drive the swing arm 110 to move upwards or downwards, allowing the swing arm 110 to switch from one of the first position and the second position to the other.

[0016] Please see Figure 3 and Figure 4 The housing 120 has a constraint part 121, and the swing arm 110 has a constraint engagement part 111, which cooperates with the constraint part 121. Specifically, one of the constraint engagement part 111 and the constraint part 121 can be a groove structure, and the other can be a block structure. The groove structure and the block structure cooperate with each other, allowing the swing arm 110 to move along a predetermined path. Alternatively, in other cases, one of the constraint engagement part 111 and the constraint part 121 is a guide rail, and the other is a slider that slides with the guide rail; this will not be elaborated further here.

[0017] Please see Figure 3 The swing arm 110 has a support portion 112. When the swing arm 110 is in the first position, the support portion 112 is used to support and fix the material along the first direction L1. The material can be leather, paper, metal sheet, or a combination of at least two, etc., and this application does not limit this. Figure 5 As shown, for example, the support portion 112 can be a sheet-like structure or a block-like structure, and the support portion 112 can have a support surface. When the swing arm 110 is in the first position, the support surface can abut against and support the material, preventing the material from shaking or tilting during the cutting process.

[0018] Please see Figure 5When the drive shaft 131 drives the swing arm 110 from the first position to the second position, the constraint part 121 guides the constraint engagement part 111 so that the support part 112 moves sequentially along the first path and the second path. The first path extends along the first direction L1, and at least a portion of the extension direction of the second path intersects the first direction L1. The first path can be a straight path, and the second path can be an arc path or a bent straight path, etc.

[0019] Specifically, in the initial state, the support part 112 supports and positions the material along the first direction L1, the swing arm 110 is in the first position, and the constraint part 121 and the constraint mating part 111 are in the initial mating state. Please refer to [link / reference]. Figure 6 After the drive unit 130 starts working, the drive shaft 131 drives the swing arm 110 to move from the first position to the second position. Simultaneously, the swing arm 110 drives the constraint engagement part 111 to move. The constraint part 121 guides and limits the constraint engagement part 111, causing the support part 112 to first move linearly along the first path, gradually moving away from the material to release the support and limitation on the material in the first direction L1. Please refer to... Figure 7 Subsequently, under the continuous guidance of the constraint part 121, the support part 112 changes its direction of movement and continues to move along a second path that intersects the first direction L1 at least partially along its extension direction until the swing arm 110 reaches the second position. At the same time, the support part 112 moves to the preset avoidance position. At this time, the swing arm 110 can move away from the cutting assembly 200 and the location of the material, thereby creating sufficient operating space under the cutting assembly 200 and the material to facilitate operations such as changing materials or the cutting tool of the cutting assembly 200.

[0020] This application utilizes an orderly movement—with the support part 112 first releasing its support limit and disengaging from mutual contact before proceeding with avoidance—to effectively prevent unexpected thrust on the material during the movement of the support part 112, thus eliminating material deviation and ensuring material processing positioning accuracy and finished product quality. Simultaneously, it provides ample space for subsequent material loading and unloading operations. Furthermore, this design, through the cooperation of the constraint part 121 and the constraint mating part 111, enables continuous movement of the support part 112 in multiple directions, achieving avoidance maneuvers within the same space with a more compact movement trajectory. Compared to a single linear avoidance method, multi-directional continuous avoidance effectively shortens the overall movement stroke, thereby reducing the space required for component movement. In addition, compared with the existing technology, which requires the addition of intermediate transmission components such as connecting rods and cams or the addition of drive structures such as drive motors and cylinders to achieve multi-directional movement, the material auxiliary fixing device 100 of this application achieves motion conversion through the cooperation between the constraint part 121 and the constraint mating part 111. It does not require the addition of intermediate transmission components such as connecting rods and cams, nor does it require the addition of a drive structure. The transmission chain is simpler, and the overall motion stroke is more compact, and the movement space of each component is significantly reduced.

[0021] Furthermore, the material auxiliary fixing device 100 can complete the compound motion of two paths with only a single driving component 130, without the need for additional driving components. While reducing the number of parts, it can effectively reduce the overall volume and size of the material auxiliary fixing device 100, which is conducive to achieving miniaturization and compact design, reducing its requirements for installation space, expanding the applicable working conditions, and thus improving the application scenarios and scope of the material auxiliary fixing device 100.

[0022] In the embodiments of this application, please refer to Figure 8 One of the constraint part 121 and the constraint mating part 111 is provided with a constraint groove, and the other is provided with a first constraint member (such as a cylindrical pin, roller, etc.). The first constraint member is movably installed in the constraint groove and slides along the constraint groove. For example, as shown in the figure... Figure 8 As shown, the constraint portion 121 on the housing 120 has a constraint groove, and the constraint mating portion 111 on the swing arm 110 is provided with a first constraint member. At least a portion of the first constraint member is embedded in the constraint groove and slides along the constraint groove. Of course, in some other cases, the constraint mating portion 111 has a constraint groove, the constraint portion 121 is provided with a first constraint member, and at least a portion of the first constraint member is embedded in the constraint groove; this is not a limitation here. For ease of subsequent description, as... Figure 8 As shown, the following description will be based on the example of a constraint part 121 having a constraint groove and a constraint mating part 111 having a first constraint member.

[0023] This embodiment of the application limits the movement path of the first constraint member by using a preset trajectory of the constraint groove, thereby controlling the movement trajectory of the support part 112 and ensuring that the support part 112 moves in an orderly manner along the first path and the second path. For example, a portion of the constraint groove extends along the first direction L1, and another portion extends along the second direction L2. Under the driving action of the drive shaft 131, the swing arm 110 continuously moves along the first direction L1. During this process, the constraint groove effectively constrains the first constraint member, guiding it to move gradually along the first direction L1 and the second direction L2. It should be noted that when the first constraint member moves along the second direction L2, the drive shaft 131 will continue to apply a driving force along the first direction L1 to the swing arm 110. At this time, the support part 112 will be simultaneously subjected to the driving force of the drive shaft 131 and the guiding constraint force of the constraint part 121. Under the combined action of these two forces, the support part 112 will swing in the direction of the resultant force. Specifically, while continuing to move along the first direction L1, the support part 112 will swing around the connection between the drive shaft 131 and the swing arm 110. This structure can achieve controllable setting of the movement trajectory of the support part 112 through the synergistic effect of the constraint groove and the drive shaft 131, and the overall structure is simple and the guiding effect is stable and reliable.

[0024] In the embodiments of this application, please refer to Figure 8 The constraint groove includes a first segment 1211 and a second segment 1212. The first segment 1211 extends along a first direction L1 and connects to the second segment 1212. At least a portion of the extension direction of the second segment 1212 intersects the first direction L1. Furthermore, when the first constraint member slides along the first segment 1211 of the constraint groove, it causes the support portion 112 to move linearly along the first direction L1, thereby enabling the support portion 112 to move away from the material and release its support limit. When the first constraint member enters the second segment 1212 from the first segment 1211, since the extension direction of the second segment 1212 intersects the first direction L1, it guides the first constraint member to change its direction of movement, thereby causing the support portion 112 to switch to a second path of movement, completing the avoidance action. The first segment 1211 and the second segment 1212 of the constraint groove ensure the continuity of the first constraint member's movement, avoid movement jamming, and achieve controllable setting of the movement path of the support portion 112.

[0025] In one embodiment, the first segment 1211 can be a straight groove, the extension direction of which is parallel to the first direction L1. The straight groove can ensure that the first constraint member slides smoothly along a straight line, thereby driving the support part 112 to make a uniform and straight away movement, avoiding the support part 112 from shaking or deviating during the release of the support limit, and preventing the unstable movement of the support part 112 from indirectly affecting the material positioning.

[0026] In another implementation, please refer to Figure 8 A third segment 1213 is provided between the first segment 1211 and the second segment 1212, and at least a portion of the third segment 1213 is a smoothly transitioning arc-shaped groove. The smooth transition of the arc-shaped groove allows for a smooth change in the direction of movement when the first constraint member moves from the first segment 1211 to the second segment 1212, avoiding jamming and impact, reducing component wear, and extending the service life of the structure. Simultaneously, the smooth transition motion trajectory makes the movement of the support portion 112 more gradual, further ensuring the stability of material positioning. The arc-shaped groove also optimizes the stress distribution of the constraint groove, reduces stress concentration, and improves the structural strength of the constraint groove.

[0027] A constraint groove is formed in the constraint part 121, and a first constraint member is disposed in the constraint mating part 111. The first constraint member is rotatably disposed relative to the swing arm 110. For example, the first constraint member can be a wheel, which is rotatably disposed relative to the swing arm 110. The friction between the first constraint member and the groove wall of the constraint groove is rolling friction, which allows the first constraint member to slide along the constraint groove and adapt to the swinging motion, reducing the friction between the first constraint member and the groove wall of the constraint groove, improving the flexibility of movement and service life.

[0028] In the embodiments of this application, please refer to Figure 3One of the housing 120 and the swing arm 110 is provided with a constraint surface 113, and the other is provided with a second constraint member 126. The second constraint member 126 slides against the constraint surface 113 to provide at least the support part 112 with power to move along the second path. When the drive shaft 131 drives the swing arm 110 to move along the first direction L1, the second constraint member 126 always maintains close contact with the constraint surface 113, so that the swing arm 110 can obtain axial driving force and also generate force along the trajectory of the constraint surface 113. This force provides kinetic energy to the swing arm 110, realizing the switch of the support part 112 from the movement on the first path to the movement on the second path, avoiding movement jamming or trajectory loss of control caused by a single guiding action, and at the same time providing reliable power support for the change of direction of the support part 112.

[0029] In this embodiment of the application, the constraint surface 113 includes a first segment 1131, a second segment 1132 and a third segment 1133 connected together. The second segment 1132 is located between the first segment 1131 and the third segment 1133. During the process of the swing arm 110 moving from the first position to the second position, the second constraint member 126 can pass through the first segment 1131, the second segment 1132 and the third segment 1133 in sequence.

[0030] In one implementation, please refer to the following: Figure 3 , Figure 6 as well as Figure 7 The first segment 1131 extends along the first direction L1. Along the first direction L1, the second segment 1132 is inclined towards the direction close to the second constraint member 126. Guided by the second segment 1132, the support part 112 moves along the second path. When the second constraint member 126 slides along the first segment 1131, the support part 112 can only move linearly along the first direction L1, releasing the support limit on the material. When the second constraint member 126 enters the inclined second segment 1132, under the guidance of the inclined surface, the axial driving force is decomposed into axial and lateral components, driving the support part 112 to move along the second path intersecting the first direction L1. This achieves the avoidance movement of the support part 112 without requiring an additional drive source, simplifying the device structure while ensuring precise control of the movement trajectory.

[0031] In another embodiment, the third segment 1133 extends perpendicularly to the first direction L1. When the swing arm 110 is in the first position, the third segment 1133 abuts against the second constraint member 126 along the first direction L1. When the swing arm 110 moves from the second position to the first position, the third segment 1133 abuts against the second constraint member 126 along the first direction L1 to limit the travel of the swing arm 110 and prevent it from moving beyond its travel along the first direction L1. This arrangement ensures accurate movement to the first position and avoids component collisions, jamming, or structural deformation caused by excessive movement, providing a constraint effect for the stable operation of the mechanism.

[0032] In the embodiments of this application, please refer to Figure 3 The housing 120 has a receiving cavity 122 with an opening 123. A portion of the swing arm 110 is located within the receiving cavity 122, with at least the support portion 112 extending out of the housing 120 through the opening 123. This arrangement allows at least a portion of the swing arm 110 to be housed within the housing 120, providing protection for the component and preventing dust and debris from affecting motion accuracy. It also allows the support portion 112 to extend independently out of the housing 120 to support the material, resulting in clear separation between internal transmission and external support functions without interference. This arrangement makes the material auxiliary fixing device 100 more compact, reducing the size of the cutting equipment 1 and ensuring reliable support positioning.

[0033] Please see Figure 3 The receiving cavity 122 has a first cavity wall 1221 disposed opposite to the swing arm 110. At the opening 123, the first cavity wall 1221 bends and extends away from the swing arm 110 to form an open opening 123. The open opening 123 provides sufficient space for the swinging motion of the swing arm 110, avoiding interference between the swing arm 110 and the housing 120 during movement. The open design facilitates the assembly and maintenance of the swing arm 110, while reducing the restriction on the movement of the swing arm 110 by the housing 120, allowing the support 112 to obtain a larger swing angle during avoidance, and providing more ample operating space for material change or tool maintenance.

[0034] In another embodiment, the receiving cavity 122 has a second cavity wall 1222, which is provided with a clearance groove 125. The clearance groove 125 is used to avoid the swing arm 110. A protrusion 124 is provided between the clearance groove 125 and the opening 123. The protrusion 124 is located on the movement path of the swing arm 110 and is used to limit the movement stroke of the swing arm 110. The clearance groove 125 can adapt to the movement trajectory of the swing arm 110, avoiding collision between the swing arm 110 and the housing 120 during swinging, and ensuring smooth movement. The protrusion 124 can limit the swing arm 110 at its extreme position, preventing damage to the swing arm 110 due to overtravel, and at the same time preventing the support part 112 from excessively avoiding the material, which would cause it to be unable to align with the material during subsequent reset, thus improving the movement stability and repeatability accuracy of the device.

[0035] In the embodiments of this application, please refer to Figure 3 and Figure 9 A drive block 1311 is mounted on the drive shaft 131, and the drive block 1311 is rotatably connected to the swing arm 110. The drive block 1311 is provided with an abutment member 141, which engages with the inner wall of the housing 120 (i.e., the cavity wall of the receiving cavity 122, etc.) to limit the movement of the drive block 1311 in the first direction L1. For example, the abutment member 141 is a roller, and the abutment member 141 forms a rolling friction engagement with the inner wall of the housing 120 to reduce wear between the two. This arrangement, through the mutual abutment engagement between the abutment member 141 and the inner wall of the housing 120, can stably transmit the linear driving force of the drive shaft 131 to the swing arm 110, while limiting the radial movement of the drive block 1311 and preventing deviation of the swing arm 110's movement trajectory due to the offset of the drive block 1311. The rotational connection between the drive block 1311 and the swing arm 110 allows the swing arm 110 to rotate freely when moving along the constraint surface 113, achieving coordinated linear driving force and guiding motion. This ensures efficient power transmission and enables the composite motion of the swing arm 110. The structure is simple and reliable, and the transmission efficiency is high.

[0036] Please see Figure 9 and Figure 10 The drive block 1311 is provided with a connecting shaft 142, which is rotatably connected to the swing arm 110. The abutment member 141 is sleeved on the connecting shaft 142. The extending direction of the connecting shaft 142 intersects the first direction L1, such as... Figure 10 As shown, Figure 10A three-dimensional coordinate system is established, with the first direction L1 being the z-axis direction, the second direction L2 being the y-axis direction, and the extension direction of the connecting shaft 142 being the x-axis direction. The abutment member 141 can abut against the inner wall of the housing 120 approximately along the y-axis direction. The projection of the drive block 1311 and the swing arm 110 along the x-direction coincides. The drive block 1311 and the swing arm 110 are connected by the connecting shaft 142. This arrangement transforms the connection structure along the z-axis direction into a connection structure along the y-axis direction, realizing the staggered arrangement of the drive block 1311 and the swing arm 110 in space. This can further reduce the overall size of the material auxiliary fixing device 100, which is beneficial for the miniaturization and compact design of the material auxiliary fixing device 100.

[0037] The drive block 1311 has a receiving groove 1312, the connecting shaft 142 is disposed in the receiving groove 1312, and the abutment 141 is sleeved on the connecting shaft 142 and received in the receiving groove 1312. The receiving groove 1312 can provide radial and circumferential limiting for the abutment 141, so that the abutment 141 always maintains a stable posture during operation and ensures that it can reliably abut in a predetermined direction. At the same time, the groove wall of the receiving groove 1312 can form a wrap-around protection for the connecting shaft 142, improving its protection capability. There is no need to reduce the overall thickness of the drive block 1311 to accommodate the connecting shaft 142, thereby effectively ensuring the overall structural strength and load-bearing capacity of the drive block 1311.

[0038] This application also provides a cutting device 1, please refer to... Figure 1 The cutting equipment 1 may include a material auxiliary fixing device 100, which enables the cutting equipment 1 to have the beneficial effects of any of the aforementioned solutions, and will not be elaborated here.

[0039] In one implementation, please refer to Figure 1 The cutting device 1 also includes a cutting assembly 200, which cooperates with the support portion 112 to fix the material. Specifically, the cutting assembly 200 includes a clamping structure with an abutment surface that can contact and compress the material. An installation space is provided between the clamping structure and the support portion 112 to accommodate the material. The material can be pressed against the support portion 112 by the clamping structure, and the clamping structure and the support portion 112 can act relative to each other to fix the material.
