Description

Technical Field

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

[0002] A cutting device is a processing equipment for shaping and cutting blanks, such as cutting insole blanks according to preset insole dimensions and contour paths to produce insoles of corresponding sizes 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 performs reciprocating cutting to complete the contour cutting of the blank.

[0003] However, the existing cutting devices suffer from poor blade motion stability, making them prone to wear with other components, which reduces the lifespan of the cutting equipment and compromises its reliability. To improve motion stability, the assembly precision requirements of the cutting device must be increased, affecting both assembly accuracy and efficiency. Summary of the Invention

[0004] The purpose of this application is to provide a fixing clamp device and a cutting equipment to solve the above-mentioned technical problems existing in the prior art.

[0005] In a first aspect, embodiments of this application provide a fixing fixture device, which includes a housing and a driving member. The driving member is movably disposed on the housing. The housing has a first mounting cavity with a first opening. The first mounting cavity is used to mount a fixed shaft, and the fixed shaft is used to mount a cutting tool. The housing has a limiting mating surface. Along the axial direction of the first cavity, the limiting mating surface can be disposed opposite to the limiting surface of the fixed shaft. The driving member is used to drive the fixed shaft to be movably disposed along the central axis of the first opening, so that the limiting surface can abut against the limiting mating surface along the radial direction of the driving member.

[0006] Secondly, embodiments of this application provide a cutting device including a fixing clamp device as described in the first aspect, and the cutting device further includes a fixing shaft mounted in a first mounting cavity.

[0007] The technical solution adopted in this application achieves the following beneficial effects: the fixed shaft can be installed on the housing, and the fixed shaft is movably arranged relative to the housing. The power source can drive the fixing fixture device, which is driven and drives the fixed shaft to move. The driving component can be limited and matched with the fixed shaft to fix the fixed shaft relatively to the housing. The fixed shaft is equipped with a cutting tool, and during the movement of the fixing fixture device and the fixed shaft, the cutting tool reciprocates to cut the blank to manufacture products such as shoe insoles.

[0008] Compared to existing technologies, the fixed shaft in this embodiment has a limiting surface on its outer surface, and the fixing fixture has a limiting mating surface, which is arranged opposite to the limiting surface. The fixing fixture is equipped with a driving member. The driving member drives the fixed shaft to move along the axis of the first opening, allowing the limiting surface to abut against the limiting mating surface radially along the driving member. This mutual contact between the limiting surface and the limiting mating surface eliminates radial wobble between the fixed shaft and the fixing fixture, preventing radial deviation forces from the power source transmitting to the fixing fixture, which could cause offset or uneven wear of the fixed shaft, thus improving the service life and reliability of the fixing fixture. Simultaneously, this reduces tool wobble, making the cutting process smoother and preventing rough or broken edges on the blank due to unstable cutting. Furthermore, eliminating radial clearance through the driving member reduces the assembly accuracy requirements of the fixed shaft and the fixing fixture, improving the overall production quality and efficiency of the cutting equipment.

Detailed Implementation

[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.

[0013] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. 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] In existing cutting devices, when the power source drives the cutter to reciprocate through the transmission rod, the transmission rod is easily subjected to radial force and causes abnormal wear with other components. The cutter has poor motion stability and is prone to deviation, which affects the cutting effect and results in an overly rough finished surface.

[0015] Specifically, the cutting device includes a power source, a transmission rod, a cutting tool, and a drive rod. The power source drives the transmission rod, which converts the horizontal rotational force into a force that moves the drive rod vertically. The drive rod then drives the cutting tool in a reciprocating motion in the vertical direction. During this process, the transmission rod may generate a radial component force. If the drive rod's fixation is not as effective as intended, it can cause radial wobble under the influence of this component force. This can lead to uneven wear between the drive rod and other components such as the housing. Simultaneously, the poor motion stability of the cutting tool, which is connected to the drive rod, can cause wobble during operation, resulting in an excessively rough cut surface on the finished product.

[0016] An embodiment of this application provides a fixing clamp device 100. Please refer to [link to relevant documentation]. Figure 1 as well as Figure 2 By having the fixed shaft 210 and the driving component 120 radially abut against each other, radial wobble of the fixed shaft 210 and the tool 220 on it is reduced or avoided, thereby improving the cutting stability of the tool 220 and alleviating or solving the above problems.

[0017] Please see Figure 2 The fixing clamp device 100 includes a housing 110 and a driving member 120, with the driving member 120 movably disposed on the housing 110.

[0018] Please see Figure 2 as well as Figure 3 The housing 110 can be a metal housing or a polymer housing, etc., without limitation. The housing 110 is provided with a first mounting cavity 1111, which has a first opening 112. The first mounting cavity 1111 is used to mount a fixed shaft 210, which is used to mount a cutting tool 220. The fixed shaft 210 can extend into the first mounting cavity 1111 through the first opening 112. The fixed shaft 210 can be mounted on the housing 110 and is movably disposed relative to the housing 230. The power source 240 can drive the fixing clamp device 100, which, when driven, moves the fixed shaft 210 along with it, and its movement direction can be reciprocating in the vertical direction. The driving member 120 can engage with the fixed shaft 210 to limit its movement, so that the fixed shaft 210 is relatively fixed on the housing 110. The fixed shaft 210 is equipped with a cutting tool 220. During the movement of the fixed clamping device 100 and the fixed shaft 210, the cutting tool 220 reciprocates to cut the blank to manufacture products such as insoles and leather goods.

[0019] Please see Figure 3The housing 110 has a limiting mating surface 113. Along the axial direction of the first cavity 114, the limiting mating surface 113 can be disposed opposite to the limiting surface 217 of the fixed shaft 210. The driving member 120 is used to drive the fixed shaft 210 to move along the central axis of the first opening 112, so that the limiting surface 217 can abut against the limiting mating surface 113 in the radial direction of the driving member 120. Furthermore, the outer surface of the fixed shaft 210 is provided with a limiting surface 217, and the fixing clamp device 100 has a limiting mating surface 113. The limiting mating surface 113 can be provided at the first opening 112 or on the inner wall of the first mounting cavity 1111, etc., and the limiting mating surface 113 and the limiting surface 217 are disposed opposite to each other. The fixed clamping device 100 is equipped with a driving member 120, which drives the fixed shaft 210 to move along the axis of the first opening 112, so that the limiting surface 217 can abut against the limiting mating surface 113 radially along the driving member 120. This mutual contact between the limiting surface 217 and the limiting mating surface 113 eliminates radial wobble between the fixed shaft 210 and the fixed clamping device 100, preventing offset or uneven wear of the fixed shaft 210 due to radial deviation forces transmitted from the power source 240 to the fixed clamping device 100, thus improving the service life and reliability of the fixed clamping device 100. Simultaneously, the driving member 120 can also fix the fixed shaft 210 to the housing 110, which reduces the wobble of the tool 220, making it more stable during blank cutting and preventing rough or broken blank edges caused by unstable cutting. In addition, by eliminating radial fit clearance through the drive component 120, the assembly accuracy requirements of the fixed shaft 210 and the fixed clamping device 100 are reduced, thereby improving the overall production quality and efficiency of the cutting equipment 200.

[0020] In the embodiments of this application, please refer to Figure 3 The housing 110 may be provided with a first cavity 114. The shape and size of the first cavity 114 are not limited. For example, the shape of the first cavity 114 may be a cylinder, a cube, etc., and its cross-sectional dimensions may be the same as the cross-sectional dimensions of the driving member 120. The driving member 120 is movably mounted in the first cavity 114, such as being able to move along the extension direction of the first cavity 114. Further, the first cavity 114 is a cubic cavity, and the driving member 120 can be movably disposed along its length direction.

[0021] Please see Figure 2The first cavity 114 connects to the first mounting cavity 1111, and the drive member 120 is movably mounted in the first cavity 114. This allows at least a portion of the drive member 120 to enter the first mounting cavity 1111. It should be noted that at least a portion of the drive member 120 extends outside the housing 110, and the assembler can adjust its relative position by manipulating the drive member 120. Alternatively, in some other cases, the fixing clamp device 100 is provided with fasteners, such as screws or bolts, which are movably mounted in the housing 110 and drively connected to the drive member 120. Their relative position can be adjusted by rotating the fasteners. When the drive member 120 moves along the direction from the first cavity 114 to the first mounting cavity 1111, the fixing shaft 210 moves in a direction closer to the fixing clamp device 100. The drive member 120 exerts a thrust on the fixing shaft 210 mounted in the first mounting cavity 1111, causing the fixing shaft 210 to move in a direction closer to the fixing clamp device 100. When the drive member 120 moves along the direction from the first cavity 114 to the first mounting cavity 1111, the fixed shaft 210 moves along the direction closer to the housing 110. It should be noted that when the thrust or constraint force generated by the drive member 120 on the fixed shaft 210 disappears, the fixed shaft 210 moves away from the fixed clamping device 100 under its own weight or external force, so that the fixed shaft 210 can be disassembled or its relative position adjusted. This setting allows adjustment of the relative position between the fixed shaft 210 and the fixed clamping device 100 by adjusting the relative position of the drive member 120, so that a suitable preload is formed between the limiting surface 217 and the limiting mating surface 113 and they abut against each other. This reduces the wobble of the tool 220, making it more stable during the blank cutting process and avoiding rough or broken blank edges due to unstable cutting.

[0022] In one implementation, please continue reading Figure 2 The driving component 120 is provided with a first guide surface 121, which extends away from the first opening 112 along the direction from the first cavity 114 to the first mounting cavity 1111. The first guide surface 121 can be an inclined surface or an arc surface, etc., and is not limited thereto. The fixed shaft 210 is provided with a second guide surface 211, and the first guide surface 121 and the second guide surface 211 cooperate with each other. Through the close cooperation of the first guide surface 121 and the second guide surface 211, the force of the driving component 120 can be transmitted to the fixed shaft 210, thereby driving the fixed shaft 210 to move in a preset direction to adjust the relative position of the fixed shaft 210. The surface-to-surface contact reduces the force loss between the driving component 120 and the fixed shaft 210, ensuring smooth power transmission and preventing jamming during their cooperation. This allows the fixed shaft 210 to be accurately fixed to the predetermined position of the fixing clamp device 100.

[0023] In some other embodiments, the fixed shaft 210 is provided with multiple teeth, which are spaced apart along the central axis of the fixed shaft 210. The driving member 120 can be a gear, and the driving member 120 is rotatable relative to the housing 110. The driving member 120 meshes with the teeth of the fixed shaft 210, and by controlling the rotation of the driving member 120, the relative position between the fixed shaft 210 and the fixed clamping device 100 is adjusted, so that a suitable preload is formed between the limiting surface 217 and the limiting mating surface 113 and they abut against each other. At this time, the relative position of the driving member 120 is fixed by structures such as buckles and limiting posts, so that the limiting surface 217 and the limiting mating surface 113 continuously abut against each other, thereby reducing the wobbling of the tool 220, etc., which will not be described in detail here.

[0024] It should be noted that, in one scenario, the limiting mating surface 113 is correspondingly positioned to the first opening 112. When the fixed shaft 210 is installed within the first mounting cavity 1111, the limiting mating surface 113 and the limiting surface 217 are correspondingly positioned along the axis of the fixed shaft 210. Preferably, the limiting mating surface 113 is located on the wall surrounding the first opening 112, and the limiting mating surface 113 can be arranged around the periphery of the first opening 112. The limiting mating surface 113 and the limiting surface 217 can correspond to a preset position, providing a basis for the subsequent limiting and positioning of the fixed shaft 210, ensuring the accurate installation position of the fixed shaft 210 within the first mounting cavity 1111, and avoiding any offset that could affect the limiting effect.

[0025] In addition to driving the cutting tool 220 and its connected fixed shaft 210, the fixing fixture device 100 also needs to drive other components to move together, such as pressing parts for pressing the blank or semi-finished product, and other cutting tools. Please refer to Figure 4 as well as Figure 5In this embodiment, the driving component 120 includes a first driving block 122, a second driving block 123, and a synchronizing block 124. The synchronizing block 124 is transversely connected to the first driving block 122 and the second driving block 123. The first driving block 122 drives the first fixed shaft 212 to move towards the housing 110, and the second driving block 123 drives the second fixed shaft 213 to move towards the housing 110. The first fixed shaft 212 is used to mount the tool 220, and the second fixed shaft 213 is used to mount the mating component. The mating component includes a pressing component suitable for pressing against the workpiece to be cut, other tools, etc., and is not limited thereto. For ease of description, the following description uses a pressing component as an example. Exemplarily, the fixed shaft 210 may include a first fixed shaft 212 and a second fixed shaft 213, both of which are columnar structures. Specifically, the pressing member is movably disposed relative to the second fixed shaft 213, and an elastic member is disposed between the pressing member and the second fixed shaft 213. The elastic member can drive the pressing member to move away from the second fixed shaft 213, which can at least press against the area of ​​the blank to be cut, ensuring the stability of subsequent cutting. Preferably, the pressing member and the blank surface abut against each other to increase the contact area and improve cutting stability.

[0026] For further details, please refer to Figure 5The synchronizing block 124 may be provided with a first inclined surface 1241 and a second inclined surface 1242. The first driving block 122 has a first mating surface 1221, which mates with the first inclined surface 1241. The second driving block 123 has a second mating surface 1231, which mates with the second inclined surface 1242. Both the first mating surface 1221 and the second mating surface 1231 are inclined surfaces. When the synchronizing block 124 moves, it presses against the first mating surface 1221 and the second mating surface 1231, forcing the first driving block 122 and the second driving block 123 to move synchronously. Assemblers can drive the synchronizing block 124 by directly turning it or using other fasteners; this is not a limitation. The synchronizing block 124 has different first and second positions. During the process of switching the synchronizing block 124 from the first position to the second position, the synchronizing block 124 can drive both the first driving block 122 and the second driving block 123 to move in a direction away from the synchronizing block 124. Through the transmission action of the synchronization block 124, the first drive block 122 and the second drive block 123 move synchronously. This enables the first fixed shaft 212 and the second fixed shaft 213 to drive synchronously, allowing the pressing component to press against the workpiece to be cut, so that the cutter 220 can cut synchronously and neatly. This ensures that the cutter 220 and the pressing component can work together, meeting the synchronous requirements of the pressing and cutting operations during the cutting process, and improving the stability and efficiency of the cutting operation. At the same time, the assembly personnel only need to adjust the synchronization block 124 to complete the assembly adjustment of the first fixed shaft 212 and the second fixed shaft 213, reducing assembly steps and improving assembly accuracy and efficiency.

[0027] An embodiment of this application provides a cutting device 200, please refer to... Figure 6 The cutting device 200 includes the aforementioned fixing clamp device 100 and fixing shaft 210, with the fixing shaft 210 mounted in the first mounting cavity 1111. This gives the cutting device 200 the beneficial effects of any of the aforementioned solutions, which will not be elaborated further here.

[0028] In the embodiments of this application, please refer to Figure 7The cutting equipment 200 may further include a housing 230, a power source 240, and a transmission component 250. The transmission component 250 is drively connected between the power source 240 and the fixing clamp device 100. The fixing shaft 210, the fixing clamp device 100, and the power source 240 are installed inside the housing 230. The housing 230 may be a metal housing or a polymer housing, etc., and is not limited thereto. The housing 230 may have a receiving cavity that can accommodate the fixing shaft 210, the fixing clamp device 100, and the power source 240. It can provide protection for the fixing shaft 210, the fixing clamp device 100, and the power source 240. For example, at least a portion of the fixing shaft 210 extends into the housing 230, and the power source 240 can be installed in the housing 230. Relative to the housing 230, the fixing shaft 210 is vertically movable.

[0029] In one implementation, please continue reading Figure 7 At least a portion of the fixed shaft 210 extends out of the housing 230. A power source 240 drives a transmission component 250 to rotate about a first axis. The transmission component 250 receives power from the power source 240 and provides power for the fixed clamping device 100 to reciprocate along the first axis. The first axis and the central axis of the first opening 112 are parallel or collinear. The fixed shaft 210 and the power source 240 can be mounted on the housing 230. The fixed shaft 210 is movably arranged in the vertical direction relative to the housing 230. For example, the housing 230 may have a through hole that penetrates the housing 230. The central axis of the through hole extends vertically and corresponds to the first opening 112. The fixed shaft 210 is movably mounted in the through hole. At least a portion of the fixed shaft 210 extends outside the housing 230 and connects to the cutting tool 220. The constraint of the through hole allows the fixed shaft 210 to drive the cutting tool 220 to move vertically. Meanwhile, by using the limiting mating surface 113 and the limiting surface 217 to cooperate with each other, the radial clearance between the fixed shaft 210 and the fixed clamping device 100 can be reduced, avoiding wear between the fixed shaft 210 and the hole wall of the through hole, and improving the service life and reliability of the cutting equipment 200.

[0030] In the embodiments of this application, please continue to refer to Figure 7 The transmission component 250 is connected between the fixed clamping device 100 and the power source 240. The fixed shaft 210 is movably mounted on the fixed clamping device 100. The power source 240 drives the transmission component 250 to rotate around the first axis. The transmission component 250 receives power from the power source 240 and provides power for the fixed clamping device 100 to reciprocate along the first axis. It should be noted that the fixed shaft 210 cooperates with the through hole of the housing 230 so that both the fixed shaft 210 and the fixed clamping device 100 connected thereto can move in the vertical direction.

[0031] Specifically, such as Figure 8 as well as Figure 9 As shown, the transmission component 250 has different first and second states. (As...) Figure 8 As shown, the transmission component 250 is in the first state, while the fixing clamp device 100 and the fixing shaft 210 are at their lowest points in the vertical direction. Figure 9 As shown, the transmission component 250 is in the second state. Driven by the transmission component 250, the fixed clamping device 100 and the fixed shaft 210 are at their highest points in the vertical direction. The power output from the power source 240 is transmitted to the transmission component 250, causing the transmission component 250 to rotate around the first axis. The transmission component 250 converts the power into a force that drives the fixed clamping device 100 to reciprocate along the first axis, thereby changing the direction of power transmission and ensuring that the power from the power source 240 can act on the fixed clamping device 100. This allows the fixed shaft 210 and the tool 220 mounted on it to reciprocate in the vertical direction to cut the workpiece to be cut into a finished product, eliminating the need for complex gear, rack, or lead screw structures, which helps to reduce the overall size and adapt to installation in the narrow space inside a lens.

[0032] Please see Figure 10 The transmission component 250 has a first end 251 and a second end 252 that are far apart from each other. The first end 251 is hinged to the output shaft of the power source 240, and the output shaft drives the first end 251 to rotate around a first axis. The second end 252 is hinged to the fixed clamping device 100. When the first end 251 rotates around the first axis, the second end 252 can rotate around a second axis and move along the second axis. The first axis and the second axis are parallel or intersecting each other. This ensures that the transmission component 250 can stably achieve power conversion. Through the hinged connection at both ends, it can transmit the rotational power of the power source 240 and adapt to the reciprocating motion of the fixed clamping device 100, avoiding problems such as jamming or breakage of the transmission component 250 during power transmission, and ensuring the stability and reliability of power transmission.

[0033] For a better option, please continue reading. Figure 10 The first end 251 is provided with a first ball head, and the second end 252 is provided with a second ball head. The first ball head is hinged to the output shaft. The fixing clamp device 100 includes a first part and a second part, which are detachably connected to form a second mounting cavity 1112. The second ball head is movably installed in the second mounting cavity 1112. The ball head structure can achieve flexible hinge at multiple angles, reducing stress concentration during power transmission. At the same time, the detachable structure of the fixing clamp device 100 facilitates the installation and maintenance of the second ball head. The overall structural design takes into account both connection stability and ease of use.

[0034] Please see Figure 11The fixed shaft 210 may include a first segment 215 and a second segment 216, which are connected. It should be noted that the first segment 215 and the second segment 216 may be integrally formed, or, in other cases, they may be detachably connected; this is not a limitation. Furthermore, the outer diameter of the first segment 215 is larger than the outer diameter of the second segment 216, and a step is provided at the junction of the first segment 215 and the second segment 216. A limiting surface 217 is provided at the step. The step is annularly disposed on the fixed shaft 210, and the limiting surface 217 is provided on at least a portion of the step. The second segment 216 can be inserted into the first mounting cavity 1111. The step can achieve radial limiting fit through the limiting surface 217 and the limiting mating surface 113, and can also abut against the fixed clamping device 100 to limit the relative positional relationship between the fixed shaft 210 and the fixed clamping device 100, so as to provide a positioning reference for the fixed shaft 210, improve the stability and reliability of the tool 220 positioning, and avoid the situation of over-adjustment leading to damage to the drive shaft.

[0035] In the embodiments of this application, please continue to refer to Figure 7 as well as Figure 11 The outer surface of the fixed shaft 210 is provided with a notch 214. The fixed shaft 210 has a second guide surface 211, which is formed on the wall of the notch 214. At least a portion of the driving member 120 can extend into the notch 214, and the movement direction of the driving member 120 intersects the axis of the fixed shaft 210. By the driving member 120 extending into the notch 214 and cooperating with the second guide surface 211, the driving member 120 can achieve mutual contact between the limiting surface 217 and the limiting mating surface 113, eliminating radial wobble between the fixed shaft 210 and the fixed clamping device 100, and avoiding radial deviation force due to the transmission of power source 240 to the fixed clamping device 100. At the same time, the cooperation between the driving member 120 and the notch 214 can limit the separation of the fixed shaft 210 from the fixed clamping device 100, ensuring that the two always maintain a stable mating relationship and preventing the fixed shaft 210 from separating from the fixed clamping device 100. In addition, the surface-to-surface fit between the drive component 120 and the notch 214 can also ensure a stable fit between the fixed shaft 210 and the fixed clamp device 100, and prevent radial deviation of the fixed shaft 210.

[0036] It should be noted that, in one scenario, the fixed shaft 210 of this application may include a first fixed shaft 212 and a second fixed shaft 213, both of which may have notches 214, etc. Simultaneously, both the first driving block 122 and the second driving block 123 have a first guide surface 121. Furthermore, the first driving block 122 has a first guide surface 121 near the first fixed shaft 212, and the second driving block 123 also has a first guide surface 121 near the second fixed shaft 213, to improve the connection stability between the fixed shaft 210 and the fixing fixture device 100. This will not be elaborated further here. Of course, in other scenarios, the blank may be fixed by other components, including but not limited to snap-fit ​​devices, and the fixing fixture device 100 may only have one fixed shaft 210 to drive the tool 220 for cutting.
