Description

Technical Field

[0001] This application relates to the field of profile processing technology, and more specifically, to a rotatable obstacle-avoiding pressure clamp and profile processing equipment. Background Technology

[0002] In profile processing equipment, mechanical grippers typically move along the X-axis to hold and transport materials. The feeding zone conveys the material into the milling zone for processing. To ensure stability, a fixture is usually installed between the outlet of the feeding zone and the inlet of the milling zone to hold the material and prevent movement that could affect processing accuracy. In conventional solutions, since the mechanical grippers are usually located within a mounting frame and clamp the profile along the Y-axis, but not along the X-axis, an additional X-axis clamping mechanism is required. Furthermore, because the mechanical grippers need to transport the profile along the X-axis, traditional clamping mechanisms are prone to interference with the grippers. Also, when the dimensions of the transported materials vary significantly, traditional fixtures moving only in one direction are inefficient at avoiding obstacles, and back-and-forth movement is too time-consuming.

[0003] Therefore, there is an urgent need for a structure that clamps the profiles from the profile conveying direction to effectively improve the stability of profile conveying in profile processing equipment. Utility Model Content

[0004] This application proposes a rotatable obstacle-avoiding pressure clamp and profile processing equipment, aiming to solve the technical problems of poor obstacle avoidance ability, lack of versatility and flexibility of the existing pressure clamp.

[0005] Firstly, this application provides a rotatable obstacle-avoiding downward clamp, the technical solution of which is as follows:

[0006] The pressing fixture is positioned between the feeding area and the milling area of ​​the profile processing equipment. The profile workpiece is fed from the feeding area to the milling area for processing. The pressing fixture includes:

[0007] The clamping part moves up and down along the Z-axis and rotates around the Z-axis. When the profile workpiece is being processed, the clamping part fixes the profile workpiece from the Z-axis direction.

[0008] This application provides a rotatable obstacle-avoiding pressure clamp that cleverly solves the aforementioned defects of traditional clamps by introducing a liftable and rotatable clamping part into the pressure clamp. This innovative design enables the pressure clamp to maintain its clamping function while possessing excellent obstacle avoidance capabilities and flexibility, better adapting to the needs of automated production lines and improving production efficiency and product quality.

[0009] Furthermore, this application also proposes that the pressing clamp includes a lifting mechanism for driving the clamping part to move up and down along the Z-axis and a rotating mechanism for driving the clamping part to rotate around the Z-axis.

[0010] It also includes a support base, a lifting mechanism and a rotating mechanism, which are located on one side of the support base along the Y-axis. The lifting mechanism is connected to the rotating mechanism through a rotary joint, and the rotating mechanism is connected to the clamping part.

[0011] The rotating obstacle-avoiding downward clamp provided in this application has a lifting mechanism and a rotating mechanism jointly set on one side of the support base along the Y-axis, achieving a compact structure and reasonable layout. In terms of structural connection, the lifting mechanism is connected to the rotating mechanism through a rotary joint, and further connected to the clamping part through the rotating mechanism, thereby forming a power transmission path to ensure that the driving force of the lifting mechanism and the rotating mechanism can be effectively transmitted to the clamping part, realizing the precise lifting and rotating movement of the clamping part.

[0012] Furthermore, this application also proposes that the rotating mechanism includes a rotating cylinder and a rotating shaft, wherein the rotating cylinder drives the rotating shaft to rotate around the Z-axis, and the rotating shaft is connected to the clamping part.

[0013] Furthermore, this application also proposes that it further includes a first fixing block, and the rotating shaft is connected to the first fixing block through a first rotating structure. The first rotating structure includes a first rotating fitting part that fits into a groove on the outer surface of the rotating shaft, and a first connecting part that is connected to the first fixing block.

[0014] The design of this application allows the rotary shaft to rotate flexibly around the Z-axis while also receiving stable and reliable support, effectively improving the smoothness of the rotary shaft's operation and its service life, and providing structural protection for the reliable operation of the pressure clamp.

[0015] Furthermore, this application also proposes that the support base is provided with an extension plate extending along the Y-axis direction, and a rotary cylinder is horizontally disposed on the extension plate, with one end of the rotary cylinder connected to the first rotating structure and the other end connected to the extension plate.

[0016] The rotating obstacle-avoiding pressure clamp provided in this application not only makes the installation of the rotary cylinder more stable and reliable, but also effectively saves installation space, making the overall structure of the pressure clamp more compact and the layout more reasonable, which meets the application's requirements for structural compactness.

[0017] Furthermore, this application also proposes that the pressing fixture includes at least one roller arranged along the Y-axis of the support base, the roller rolls around the Y-axis to receive the input of the profile workpiece, the roller is arranged on the side near the feeding area, and the top surface of the roller is flush with the worktable above the support base.

[0018] Furthermore, this application also proposes that the pressing fixture further includes a side pressing mechanism disposed on the worktable for clamping the profile workpiece from the Y-axis direction. The side pressing mechanism includes a side pressing block and a fixed clamping block.

[0019] It also includes a slide rail, a side pressure block is set at one end of the slide rail and slides along the Y-axis, and a fixed clamping block is fixedly set on the side near the rotating mechanism.

[0020] This application provides a rotatable obstacle-avoiding pressure clamp and profile processing equipment. By further adding a side pressure mechanism, the pressure clamp is given a clamping function in the Y-axis direction. The side pressure mechanism and the clamping part cooperate to achieve three-dimensional clamping of the profile workpiece, effectively improving the stability and reliability of clamping, and ensuring the positioning accuracy and processing quality of the profile workpiece during processing. It is especially suitable for precision profile processing scenarios with high requirements for clamping stability.

[0021] Furthermore, this application also proposes that the pressing fixture further includes a side-pressure cylinder extending along the Y-axis direction, the side-pressure cylinder being horizontally disposed below the worktable, and the worktable having an opening along the Y-axis direction.

[0022] Furthermore, this application also proposes that the slide rail is provided with adjusting bolts and holes, including at least two holes, and one end of the piston rod of the side pressure cylinder passes through the opening and is connected to the adjusting bolts. By placing the adjusting bolts in different holes, the initial clamping position of the side pressure block can be adjusted to accommodate profile workpieces of different specifications.

[0023] This application provides a rotatable obstacle-avoiding pressure clamp and profile processing equipment. By further setting adjustment bolts and holes on the slide rail, the side pressure mechanism is made adjustable. This adjustable design allows the pressure clamp to quickly and easily adapt to profile workpieces of different specifications, improves the versatility and applicability of the clamp, reduces changeover and adjustment time, and improves production efficiency.

[0024] Secondly, this application also proposes a profile processing equipment, which is equipped with a rotatable obstacle-avoiding pressure clamp as described above; a feeding area is equipped with a feeding device for transporting profile workpieces along the X-axis; and a milling area is equipped with a milling processing device for processing profile workpieces.

[0025] Beneficial effects: This application sets up a pressure clamp between the feeding area and the milling area. The clamping part of the pressure clamp is designed to rotate around the Z-axis and can also be raised and lowered. By rotating the pressure clamp through the rotation mechanism, the clamp fixing efficiency and the stability of profile conveying are improved. Through the rotation and raising and lowering functions of the clamp, obstacles on the feeding gripper and the profile surface can be flexibly avoided, avoiding the interference problem between traditional clamps and mechanical grippers, reducing profile shaking and displacement, and improving processing accuracy and quality. It is especially suitable for profile processing with high precision processing requirements. The adjustable design of the clamp allows it to adapt to the processing needs of profiles of different specifications and shapes. Attached Figure Description

Detailed Implementation

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] In the field of modern profile processing technology, automated production lines have been widely used to improve processing efficiency and precision. In automated profile processing production lines, profile workpieces typically need to be transferred and fixed between the feeding zone 001 and the milling zone 003. Traditional profile processing equipment often uses fixed clamps to press and fix the profiles. However, to achieve automated feeding, mechanical grippers and other feeding devices are often used in the feeding stage. When the mechanical grippers transport the profile workpiece in the X-axis direction, the fixed pressing clamps are prone to interference with the mechanical grippers, limiting the smoothness of feeding and potentially causing equipment damage. Furthermore, for profile workpieces of different specifications and shapes, fixed pressing clamps are difficult to adjust and adapt quickly, resulting in insufficient flexibility of the production line, long changeover times, and low efficiency. To address these problems, this application proposes a rotatable obstacle-avoiding pressing clamp, aiming to solve the problems of poor obstacle avoidance capability and insufficient versatility of existing fixed pressing clamps, thereby improving the automation level and production efficiency of profile processing equipment. The core of this application is that a clamping part 100 capable of lifting and rotating is designed. Through the rotational movement of the clamping part 100, interference from the feeding mechanism can be effectively avoided, and smooth feeding can be achieved. Through the lifting movement of the clamping part 100, the profile workpiece can be reliably fixed during processing, ensuring processing accuracy.

[0034] The pressing fixture 002 refers to the device that applies pressure to the profile workpiece along the Z-axis during profile processing to achieve fixation and support. The feeding zone 001 refers to the starting position of the profile workpiece entering the processing area, and is usually equipped with a feeding device, such as a mechanical gripper, to transport the profile workpiece to the designated position. The milling zone 003 refers to the area where the profile workpiece is milled, and is usually equipped with a milling device, such as a milling cutter, to cut the profile workpiece. The clamping part 100 is the core component of the pressing fixture 002, directly contacting the profile workpiece to achieve clamping and fixing functions. Z-axis lifting refers to the movement of the clamping part 100 along the vertical direction (Z-axis), used to achieve the clamping and releasing actions of the clamping part 100. Rotation around the Z-axis refers to the rotation of the clamping part 100 around the vertical axis (Z-axis), used to achieve the obstacle avoidance function of the clamping part 100. The rotating obstacle-avoiding pressure clamp provided in this application is typically used in automated profile processing production lines, such as aluminum profile processing production lines. In these production lines, profile workpieces need to move sequentially between stations such as the feeding area 001, the pressure clamp 002, and the milling area 003 to complete processes such as feeding, clamping, and processing.

[0035] See Figure 2As shown, the clamping part 100 can not only move up and down along the Z-axis, but also rotate around the Z-axis. Some conventional fixtures only have the function of moving up and down. When the specifications of the profile workpieces processed on the production line vary greatly, conventional fixtures often adjust their position by moving up and down to accommodate different specifications of profile workpieces. This adjustment method requires the fixture to move a considerable distance, reducing the operating speed of the production line. Specifically, the profiles processed by the profile processing equipment have various sizes and specifications, and their heights in the vertical direction of the Z-axis vary. This means that when traditional fixtures clamp profiles with different heights, they need to adjust their lifting height in real time according to the size of the profile to avoid interference. This real-time adjustment method introduces uncertainty, increases the risk of collision, and requires supporting detection and corresponding control programs, increasing complexity and cost. If a lifting height that exceeds the height of all profiles is simply set, it will lead to reduced efficiency, because during the lifting process of the fixture, the profile needs to wait for it to finish lifting to avoid collision.

[0036] The clamping part 100 added in this application rotates around the Z-axis, which perfectly solves the problem of long movement time of conventional clamps. When facing large-sized profile workpieces, simply twisting the clamping part 100 slightly can immediately avoid the workpiece. After twisting a certain angle, it can perform an upward movement. At this time, the upward movement and the conveying of the profile can be carried out simultaneously, greatly improving the efficiency of clamp adjustment. This dual-degree-of-freedom design gives the downward clamp 002 excellent obstacle avoidance capability and flexibility. The specific structural form of the clamping part 100 can be designed in various ways according to the actual application scenario. For example, the clamping part 100 can adopt various shapes such as V-shaped clamping blocks, U-shaped clamping blocks, or flat clamping blocks to adapt to the clamping requirements of profile workpieces of different shapes. The material of the clamping part 100 can be selected from hard alloy, bearing steel, engineering plastics, etc., to meet the strength, wear resistance, and protection requirements under different working conditions. As one possible implementation, the clamping part 100 can be made of metal, with a clamping surface at its bottom that matches the contour of the profile workpiece. The clamping surface can be enhanced with friction textures or a rubber pad to improve clamping stability and reliability, preventing the profile workpiece from slipping during processing. Various driving methods can be used to achieve the lifting and rotating movements of the clamping part 100. For example, lifting can be achieved using a pneumatic cylinder, hydraulic cylinder, or motor. Rotation can be achieved using a rotary cylinder, motor, or servo motor. In a simplified embodiment, lifting can be driven by a linear cylinder, and rotation can be driven by a rotary cylinder. The lifting and rotating of the clamping part 100 are controlled by pneumatic pressure, offering advantages such as simple structure, low cost, and ease of maintenance. The lifting stroke and rotation angle of the clamping part 100 can be reasonably set according to actual obstacle avoidance requirements and workpiece size. For example, the lifting stroke can be set to 50-100mm, and the rotation angle can be set to 90-180° to meet the obstacle avoidance and clamping requirements of most profile processing scenarios.

[0037] Compared with traditional fixed pressure clamps, the rotatable obstacle-avoiding pressure clamp 002 provided in this application has significant technical advantages. Traditional fixed pressure clamps are simple in structure and low in cost, but in automated production lines, their obstacle avoidance capabilities are poor, their versatility is insufficient, and they are difficult to adapt to complex working environments and diverse processing requirements. This application cleverly solves the above-mentioned shortcomings of traditional clamps by introducing a liftable and rotatable clamping part 100 into the pressure clamp 002. This innovative design enables the pressure clamp 002 to maintain its clamping function while possessing excellent obstacle avoidance capabilities and flexibility, better adapting to the needs of automated production lines and improving production efficiency and product quality.

[0038] Specifically, when using the rotatable obstacle-avoiding pressure clamp provided in this application for profile processing, the workflow is roughly as follows: First, the profile workpiece enters the working area of ​​the pressure clamp 002 from the feeding area 001. At this time, the clamping part 100 of the pressure clamp 002 is in a raised and avoidance state, providing space for the profile workpiece to enter. After the feeding device (e.g., a mechanical gripper) transports the profile workpiece to the predetermined position, the clamping part 100 of the pressure clamp 002 begins to rotate, rotating at a certain angle to avoid the feeding device and prevent interference or collision. After obstacle avoidance is completed, the clamping part 100 begins to descend, pressing the profile workpiece from the Z-axis direction and firmly fixing it on the worktable. After the profile workpiece is clamped and fixed, the milling processing device in the milling area 003 begins to mill the profile workpiece. After processing, the clamping part 100 performs lifting and rotation actions again, releasing the clamp on the profile workpiece and resetting the clamping part 100 to its initial clearance state, so as to facilitate the removal of the processed profile workpiece and wait for the entry of the next profile workpiece. As can be seen from the above workflow, the rotatable obstacle-avoiding downward clamping fixture provided in this application, through the organic combination of the rotational obstacle avoidance and lifting clamping actions of the clamping part 100, achieves smooth feeding and stable processing, effectively solving the technical problems existing in the prior art, and providing strong technical support for the upgrading and development of automated profile processing production lines.

[0039] Furthermore, this application also proposes a specific structural scheme for a rotatable obstacle-avoiding pressure clamp. In order to realize the lifting and lowering function of the clamping part 100 along the Z-axis and the rotation function around the Z-axis, the pressure clamp 002 further includes a lifting mechanism 210 and a rotation mechanism 220.

[0040] See Figure 2 As shown, the lifting mechanism 210 is configured to drive the clamping part 100 to move up and down along the Z-axis, thereby enabling the clamping part 100 to clamp and release the profile workpiece. The rotating mechanism 220 is configured to drive the clamping part 100 to rotate around the Z-axis, allowing the clamping part 100 to perform obstacle avoidance operations. To achieve a compact structure and reasonable layout, the lifting mechanism 210 and the rotating mechanism 220 are jointly arranged on one side of the support base 300 along the Y-axis. In terms of structural connection, the lifting mechanism 210 is connected to the rotating mechanism 220 through a rotary joint 211, and further connected to the clamping part 100 through the rotating mechanism 220, thus forming a power transmission path to ensure that the driving force of the lifting mechanism 210 and the rotating mechanism 220 can be effectively transmitted to the clamping part 100, realizing the precise lifting and rotating movements of the clamping part 100.

[0041] Specifically, the lifting mechanism 210 provides driving force to the clamping part 100 along the Z-axis, enabling the clamping part 100 to move up and down. The lifting mechanism 210 can be implemented using various structural forms, such as a cylinder, hydraulic cylinder, electric push rod, or lead screw and nut mechanism. As a preferred embodiment, the lifting mechanism 210 can be a cylinder, using air pressure to drive the piston rod to extend and retract, thereby driving the clamping part 100 to move up and down. Using a cylinder as the lifting mechanism 210 has advantages such as simple structure, fast response speed, and easy control. The rotary joint 211 can be a rotary pressing cylinder joint, which typically contains bearings or sliding friction pairs to ensure the flexibility and reliability of the rotary connection. The rotating mechanism 220 provides rotational driving force to the clamping part 100 around the Z-axis, enabling the clamping part 100 to rotate and avoid obstacles. The rotating mechanism 220 can also be implemented using various structural forms, such as a rotary cylinder, a motor-driven rotating mechanism, or a worm gear mechanism. As a preferred embodiment, the rotating mechanism 220 can be a rotary cylinder, using air pressure to drive the rotating shaft 222 to rotate, thereby driving the clamping part 100 to rotate. Using a rotary cylinder as the rotating mechanism 220 also has advantages such as compact structure and controllable rotation angle. The specific installation positions of the lifting mechanism 210 and the rotating mechanism 220 on the support base 300 can be adjusted according to the actual structural layout, as long as the lifting mechanism 210 and the rotating mechanism 220 can effectively drive the clamping part 100 to perform lifting and rotating movements. This structural design not only ensures that the clamping part 100 can reliably achieve lifting and rotating movements, but also makes the overall structure of the pressing clamp 002 more compact and the layout more reasonable, providing a reliable structural foundation for the practical application of the pressing clamp 002.

[0042] Furthermore, this application also proposes a specific embodiment of a rotating mechanism 220, which mainly consists of a rotating cylinder 221 and a rotating shaft 222.

[0043] See Figure 2 As shown, the rotary cylinder 221 serves as the power source for the rotating mechanism 220, and its function is to generate rotational motion. The output shaft of the rotary cylinder 221 is connected to the rotating shaft 222, driving the rotating shaft 222 to rotate around the Z-axis. The rotating shaft 222 is a key component for power transmission; one end is connected to the rotary cylinder 221, and the other end is connected to the clamping part 100, thereby transmitting the rotational power generated by the rotary cylinder 221 to the clamping part 100, ultimately realizing the rotational motion of the clamping part 100 around the Z-axis.

[0044] Specifically, the rotary cylinder 221 can be selected from various types of rotary cylinders, such as vane rotary cylinders and rack and pinion rotary cylinders. As a commonly used implementation, a vane rotary cylinder can be used, which has advantages such as compact structure, large output torque, and adjustable rotation angle, meeting the performance requirements of the pressure clamp 002 for the rotary mechanism 220. The rotary shaft 222 is typically made of high-strength, wear-resistant metal materials, such as alloy steel or stainless steel, to ensure its strength and reliability during long-term operation. The connection between the rotary shaft 222 and the rotary cylinder 221 and the clamping part 100 can take various forms, such as key connection, pin connection, spline connection, or interference fit. In one possible implementation, the rotary shaft 222 can be a spline shaft, and to ensure the smoothness and accuracy of the rotation of the rotary shaft 222, bearing supports can be provided on the rotary shaft 222, for example, bearing seats can be provided at the upper and lower ends of the rotary shaft 222 to reduce the radial runout and axial movement of the rotary shaft 222.

[0045] By further defining the rotating mechanism 220 as including a rotating cylinder 221 and a rotating shaft 222, the specific structural composition and working principle of the rotating mechanism 220 are clarified. This structural design is simple, reliable, and easy to implement. It can effectively transmit the rotational power of the rotating cylinder 221 to the clamping part 100, driving the clamping part 100 to achieve precise rotational movement, and providing a specific and feasible implementation scheme for the rotational obstacle avoidance function of the pressure clamp 002.

[0046] Furthermore, this application provides a detailed design of the connection structure of the rotating shaft 222, which is connected to the first fixed block 310 via a first rotating structure 223. The first fixed block 310 is positioned on one side of the support base 300 extending along the Y-axis, providing a mounting base for the first rotating structure 223, improving the stability of the rotating shaft 222, and preventing wobbling when the driving clamping part 100 rotates. See also... Figure 2 As shown, the function of the first rotating structure 223 is to connect the rotating shaft 222 with the first fixed block 310, ensuring that the rotating shaft 222 can rotate freely relative to the first fixed block 310, while also stably supporting the rotating shaft 222 on the support base 300.

[0047] In some preferred embodiments, a second fixing block 311 is also included. The rotating shaft 222 is also connected to the second fixing block 311 via a second rotating structure 224. The second rotating structure 224 includes a second rotating fit part that fits into the outer surface of the rotating shaft 222, and a second connecting part that is fixed on the second fixing block 311. The second rotating structure 224 can be a bearing. In this case, the inner ring of the bearing, which is the second rotating fit part, is tightly fitted with the rotating shaft 222, and the outer ring of the bearing, which is the second connecting part, is fixed on the second fixing block 311, so that the rotating shaft 222 can rotate stably around the Z-axis. The second rotating structure 224 uses a bearing to connect with the rotating shaft 222, which converts sliding friction into rolling friction, reduces energy loss, and extends the service life of the equipment. The high-precision machining of the bearing ensures that the rotating shaft 222 has high precision and stability during rotation. The second fixing block 311 is also set on one side of the support base 300 extending along the Y-axis. The function of the second rotating structure 224 is to realize the connection between the rotating shaft 222 and the second fixing block 311, further improve the support stability of the rotating shaft 222, so that the rotating shaft 222 drives the clamping part 100 to rotate at an angle and remains stable, ensuring the accuracy and reliability of the rotation.

[0048] Specifically, the first rotating structure 223 includes a first rotating mating part and a first connecting part. As one possible implementation, the first rotating structure 223 can also be a bearing. The first rotating mating part, i.e., the inner ring of the bearing, fits into the groove on the outer surface of the rotating shaft 222. This fitting structure can effectively transmit rotational torque while allowing the rotating shaft 222 to rotate freely. The first connecting part, i.e., the outer ring of the bearing, is used to connect with the first fixed block 310, achieving a fixed connection between the first rotating structure 223 and the first fixed block 310, providing stable support. The first rotating mating part can also use low-friction elements such as bushings to reduce frictional resistance during the rotation of the rotating shaft 222 and improve rotational flexibility. The second rotating mating part cooperates with the first rotating structure 223 to jointly ensure the smooth rotation of the rotating shaft 222 and the reliability of the support. The groove on the outer surface of the rotating shaft 222 can be in various forms such as annular grooves, keyways, or spline grooves, matching the rotating mating parts of the first rotating structure 223 and the second rotating structure 224.

[0049] By further defining the connection between the rotating shaft 222 and the first fixed block 310 via the first rotating structure 223, and the connection between the rotating shaft 222 and the second fixed block 311 via the second rotating structure 224, the connection and support structure of the rotating shaft 222 is further refined. This dual-rotation structure design allows the rotating shaft 222 to rotate flexibly around the Z-axis while also receiving stable and reliable support, effectively improving the smoothness of operation and service life of the rotating shaft 222, and providing structural assurance for the reliable operation of the pressure clamp 002.

[0050] Furthermore, the support base 300 is provided with an extension plate 320 extending along the Y-axis direction, and the rotary cylinder 221 is horizontally arranged on the extension plate 320.

[0051] See Figure 4 As shown, the support base 300 serves as the basic support component for the pressure clamp 002, and its upper surface is typically equipped with structures such as a worktable 330. To provide installation space for the rotary cylinder 221 and achieve a more compact and rational spatial layout, the support base 300 is designed with an extension plate 320 extending along the Y-axis. The extension plate 320 can be integrally formed with the support base 300 or it can be a separate component, fixedly connected to the support base 300 by bolts, welding, or other methods. The rotary cylinder 221 is horizontally mounted on the extension plate 320, meaning the axis of the rotary cylinder 221 is parallel to the horizontal plane. This horizontal mounting method effectively utilizes the installation space provided by the extension plate 320, making the layout of the rotary cylinder 221 more compact and avoiding the rotary cylinder 221 occupying excessive space in the vertical direction.

[0052] Specifically, the rotary cylinder 221 is connected to other components at both ends to achieve its fixation on the extension plate 320 and power transmission. One end of the rotary cylinder 221 is connected to the first rotating structure 223, ensuring that the rotational motion of the rotary cylinder 221 can be smoothly transmitted to the first rotating structure 223, thereby driving the rotating shaft 222 to rotate. The other end of the rotary cylinder 221 is directly connected to the extension plate 320, for example, by fixing the cylinder body of the rotary cylinder 221 to the extension plate 320 with bolts.

[0053] By further defining the support base 300 with an extension plate 320 and horizontally mounting the rotary cylinder 221 on the extension plate 320, the installation structure and spatial layout of the rotary cylinder 221 are optimized. This structural design not only makes the installation of the rotary cylinder 221 more stable and reliable, but also effectively saves installation space, making the overall structure of the pressure clamp 002 more compact and the layout more reasonable, meeting the application's requirements for structural compactness.

[0054] Furthermore, the pressure clamp 002 includes at least one roller 400 arranged along the Y-axis direction of the support 300.

[0055] See Figure 2As shown, the roller 400 is configured to roll around the Y-axis. Its main function is to receive the profile workpiece input from the feeding area 001 and assist the profile workpiece in smoothly entering the working area of ​​the pressing fixture 002. The roller 400 is preferably located on the side closer to the feeding area 001 to better receive the profile workpiece conveyed from the feeding area 001. To ensure a smooth transition of the profile workpiece between the roller 400 and the support base 300, the top surface of the roller 400 is designed to be flush with the worktable 330 above the support base 300.

[0056] Specifically, the number of rollers 400 can be selected according to actual needs, and one or more rollers 400 can be set. When multiple rollers 400 are set, they can be arranged side by side along the Y-axis to accommodate profile workpieces of different lengths. The material of the rollers 400 is usually selected to be wear-resistant and low-friction coefficient materials, such as engineering plastics, nylon, or chrome-plated metal materials, to reduce the frictional resistance when the profile workpiece rolls on the rollers 400. The diameter and length of the rollers 400 can be reasonably designed according to the size and weight of the profile workpiece to ensure that the rollers 400 have sufficient load-bearing capacity and support area. The rollers 400 can be mounted on the support base 300 through bearings and other support structures to ensure that they can roll freely and smoothly around the Y-axis. As a preferred embodiment, the rollers 400 can be unpowered rollers, that is, the rollers 400 themselves do not have a drive device, but rely on the self-weight of the profile workpiece or external thrust to drive their rolling. This unpowered roller structure is simple, easy to maintain, and low in cost.

[0057] By further enhancing the structure of roller 400, an auxiliary feeding function is added to the pressure clamp 002. The roller 400 effectively reduces the frictional resistance of the profile workpiece when entering the working area of ​​the pressure clamp 002, making the input of the profile workpiece smoother and the positioning more accurate, improving feeding efficiency and automation level, and providing a useful auxiliary function for the automated production of profile processing equipment.

[0058] Furthermore, this application also adds a side pressure mechanism 500 to the worktable 330, which is configured to clamp the profile workpiece from the Y-axis direction.

[0059] See Figure 2 As shown, the main function of the side-pressure mechanism 500 is to further increase the clamping force in the Y-axis direction, thereby achieving three-dimensional clamping of the profile workpiece and improving the stability and reliability of the clamping. Especially during milling, it can effectively prevent the profile workpiece from shifting or vibrating, ensuring machining accuracy. The side-pressure mechanism 500 mainly consists of a side-pressure block 510 and a fixed clamping block 520. The side-pressure block 510 is configured to slide along the Y-axis direction, while the fixed clamping block 520 is fixedly disposed on the side near the rotating mechanism 220.

[0060] Specifically, the side clamping block 510 and the fixed clamping block 520 together constitute a clamping mechanism in the Y-axis direction. In operation, the side clamping block 510 moves toward the fixed clamping block 520, and the two cooperate to clamp the profile workpiece located between them in the Y-axis direction. To achieve the sliding movement of the side clamping block 510, it is mounted on a slide rail 530. The slide rail 530 extends along the Y-axis direction, providing sliding guidance for the side clamping block 510. The slide rail 530 can be fixed to the surface or below the worktable 330. The shape of the side clamping block 510 can be designed according to the contour of the profile workpiece; for example, a flat block, an arc-shaped block, or a V-shaped block can be used to improve the contact area with the profile workpiece and the clamping stability. The fixed clamping block 520 is relatively fixed in position, typically fixed to the support base 300 or the worktable 330 near the rotating mechanism 220. The shape of the fixed clamping block 520 can also correspond to that of the side clamping block 510, together forming a clamping surface in the Y-axis direction. As a preferred embodiment, the clamping surfaces of the side pressure block 510 and the fixed clamping block 520 can be provided with anti-slip textures or rubber pads to increase friction and prevent the profile workpiece from sliding during the clamping process.

[0061] By further adding a side-pressure mechanism 500, a clamping function in the Y-axis direction is added to the downward clamping fixture 002. The side-pressure mechanism 500 and the clamping part 100 cooperate with each other to realize three-dimensional clamping of the profile workpiece, which effectively improves the stability and reliability of clamping, and ensures the positioning accuracy and processing quality of the profile workpiece during the processing. It is especially suitable for precision profile processing scenarios with high requirements for clamping stability.

[0062] Furthermore, the side pressure mechanism 500 uses a side pressure cylinder 540 extending along the Y-axis as its power source.

[0063] See Figure 3 As shown, the side-pressure cylinder 540 is horizontally positioned below the worktable 330. Its piston rod extends and retracts along the Y-axis, thereby driving the side-pressure block 510 to slide along the slide rail 530, achieving a clamping action in the Y-axis direction. To achieve linkage between the side-pressure cylinder 540 and the side-pressure block 510, the worktable 330 is provided with an opening 331 along the Y-axis. The piston rod of the side-pressure cylinder 540 passes through the opening 331 and connects to the side-pressure block 510.

[0064] Specifically, the side-pressure cylinder 540 can be selected from various types of cylinders, such as standard cylinders, thin cylinders, or rodless cylinders. As a common implementation method, a standard cylinder can be used, which has advantages such as simple structure, stable output force, and easy control, and can meet the driving requirements of the side-pressure mechanism 500. The cylinder body of the side-pressure cylinder 540 can be fixed to the bottom of the worktable 330 or the support base 300 by bolts, brackets, etc. The shape and size of the opening 331 should match the piston rod of the side-pressure cylinder 540 to ensure that the piston rod can pass smoothly through the opening 331 and avoid interference between the piston rod and the edge of the opening 331. The edge of the opening 331 can be chamfered or rounded to reduce friction and wear. As a preferred implementation method, the opening 331 can be set as an elongated hole extending along the Y-axis direction to accommodate the sliding stroke of the side-pressure block 510 in the Y-axis direction.

[0065] By further specifying that the side-pressure mechanism 500 is driven by a side-pressure cylinder 540, and by horizontally positioning the side-pressure cylinder 540 below the worktable 330, the specific driving method and installation layout of the side-pressure mechanism 500 are clarified. Using the side-pressure cylinder 540 as the driving source enables automated clamping of the side-pressure mechanism 500, improving clamping efficiency and ease of operation. Positioning the side-pressure cylinder 540 horizontally below the worktable 330 and utilizing the opening 331 on the worktable 330 for power transmission makes the overall structure more compact and the layout more rational, further enhancing the practicality and reliability of the downward-pressing fixture 002.

[0066] Furthermore, the slide rail 530 is provided with adjusting bolts 531 and holes 532.

[0067] See Figure 3 and Figure 4 As shown, to enable the side-pressing mechanism 500 to clamp profile workpieces of different sizes, the slide rail 530 is provided with adjusting bolts 531 and multiple holes 532. At least two holes 532 are provided and are spaced apart along the length direction (Y-axis direction) of the slide rail 530. One end of the piston rod of the side-pressing cylinder 540 passes through the opening 331 on the worktable 330 and is connected to the adjusting bolts 531. By installing the adjusting bolts 531 in different holes 532 on the slide rail 530, the connection position between the piston rod of the side-pressing cylinder 540 and the side-pressing block 510 can be changed, thereby adjusting the initial clamping position of the side-pressing block 510 to accommodate profile workpieces of different widths or thicknesses.

[0068] Specifically, the hole 532 on the slide rail 530 can be a threaded hole for threaded connection of the adjusting bolt 531. The adjusting bolt 531 can be a threaded cylindrical pin or screw, one end of which is connected to the piston rod of the side pressure cylinder 540, and the other end is inserted into the selected hole 532 and tightened. The number and spacing of the holes 532 can be set according to the range of profile workpiece specifications that need to be adjusted. For example, there can be 3 or 4 holes 532, and the spacing between adjacent holes 532 can be set to 5mm or 10mm to meet the common profile workpiece specification adjustment requirements. When adjusting the initial clamping position of the side pressure block 510, first loosen the adjusting bolt 531, then pull the adjusting bolt 531 out of the current hole 532, move the side pressure block 510 to the new predetermined position, align the adjusting bolt 531 with the new hole 532 and insert and tighten it to complete the adjustment of the initial clamping position of the side pressure block 510.

[0069] By further adding adjusting bolts 531 and holes 532 to the slide rail 530, an adjustable function is added to the side pressure mechanism 500. This adjustable design allows the pressure clamp 002 to quickly and easily adapt to profile workpieces of different specifications, improving the versatility and applicability of the clamp, reducing changeover and adjustment time, and improving production efficiency. It is especially suitable for flexible production lines that require frequent changes in the specifications of the processed profiles.

[0070] Secondly, this application also provides a profile processing equipment that integrates the aforementioned rotatable obstacle-avoiding pressure clamp.

[0071] See Figure 1 As shown, this profile processing equipment mainly comprises three functional areas: a feeding area 001, a clamping fixture 002, and a milling area 003. The feeding area 001 is equipped with a feeding device for precisely transporting the profile workpiece to the processing station along the X-axis. The clamping fixture 002 is located between the feeding area 001 and the milling area 003, and its function is to stably and reliably clamp and fix the profile workpiece when it enters the milling area 003 for processing. The milling area 003 is equipped with a milling device for performing various milling operations on the clamped profile workpiece. Through the coordinated operation of these functional areas, an automated production process for profile workpieces, from feeding and clamping to milling, is achieved.

[0072] Specifically, the feeding device in feeding area 001 can take various forms, such as robotic grippers, pneumatic grippers, roller conveyors, or belt conveyors. As a common implementation method, a robotic gripper feeding device can be used, which has advantages such as high positioning accuracy, adjustable clamping force, and flexible movement, meeting the automated feeding requirements of profile workpieces. The milling device in milling area 003 typically includes a milling spindle, milling cutters, and a feed mechanism. The milling spindle drives the milling cutter to rotate at high speed, while the feed mechanism controls the relative movement of the milling cutter or the profile workpiece, thereby achieving milling of the profile workpiece. The milling device can select different types of milling cutters and processing parameters according to processing requirements to complete various complex milling tasks. The pressure fixture 002 plays a crucial role in the profile processing equipment, not only ensuring the stability of the profile workpiece during milling but also possessing good obstacle avoidance capabilities to adapt to the needs of automated feeding. The rotatable obstacle-avoiding pressure clamp provided in this application can meet these needs and is an ideal choice for profile processing equipment.

[0073] By applying a rotatable obstacle-avoiding pressure clamp to profile processing equipment and combining it with functional areas such as the feeding zone 001 and the milling zone 003, a complete automated profile processing system is formed. This profile processing equipment fully utilizes the technical advantages of the rotatable obstacle-avoiding pressure clamp to achieve automated feeding, stable clamping, and efficient milling of profile workpieces, significantly improving the automation level and production efficiency of profile processing and providing advanced equipment support for the development of modern profile processing technology.

[0074] This application provides a rotatable obstacle-avoiding pressure clamp for profile processing equipment. By placing the pressure clamp between the feeding area and the milling area, and providing a clamping part on the pressure clamp that can move up and down along the Z-axis and rotate around the Z-axis, the pressure clamp can avoid obstacles on the feeding mechanism or the surface of the profile workpiece through the rotation of the clamping part. This effectively avoids the spatial interference problem that may occur between traditional pressure clamps and feeding mechanisms (such as mechanical grippers), ensuring the smoothness of the feeding process, improving production efficiency and equipment reliability, and enhancing the versatility and adaptability of the clamp, enabling it to adapt to more complex working environments. When it is necessary to fix and clamp the profile workpiece, the lifting and lowering action of the clamping part can stably and reliably fix and clamp the profile workpiece from the Z-axis direction, ensuring the stability of the profile workpiece during processing and effectively preventing the workpiece from moving or vibrating during processing, thereby significantly improving the processing accuracy and quality of the profile workpiece. Compared with the prior art, the rotatable obstacle-avoiding pressing clamp provided in this application has an ingenious structural design, which can effectively solve the technical problems mentioned in the background art, such as poor obstacle avoidance ability, lack of versatility and flexibility, and significantly improve the overall performance and production efficiency of profile processing equipment.

[0075] The above description is merely an embodiment of this application and is not intended to limit the scope of protection of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
