Description

Technical Field

[0001] This application relates to the field of profile processing technology, and more specifically, to a telescopic support fixture and profile processing equipment for milling to 90 degrees. Background Technology

[0002] In profile processing equipment, there are usually milling and sawing zones. After the profile is milled, it needs to enter the sawing zone for sawing. In order to ensure the stability of the processing, clamps are usually set at the front and rear of the milling zone to clamp the profile, such as the positioning and clamping device disclosed in CN113199255A. However, the sawing zone usually has two symmetrical 45-degree inclined cutters and one 90-degree cutter. The 90-degree cutter is usually located between the two 45-degree inclined cutters, while the clamps are usually located on both sides of the two 45-degree inclined cutters. This results in a large distance between the clamps and the 90-degree cutter, which makes it easy for the 90-degree cutter to have an excessively long lever arm during the processing, leading to unstable clamping of the profile.

[0003] Therefore, there is an urgent need for a specially designed clamp for 90-degree saw blades to effectively improve the processing accuracy and stability of the sawing zone in profile processing equipment. Utility Model Content

[0004] This application proposes a telescopic support fixture and profile processing equipment for milling to 90 degrees, which improves the stability of the profile when it is sawn at 90 degrees, reduces vibration and displacement during processing, and ensures that the profile is accurately positioned during the 90-degree sawing process.

[0005] In a first aspect, this application provides a retractable support fixture for milling to 90 degrees, comprising the following technical solution:

[0006] The support fixture is set in the sawing area of ​​the profile processing equipment. The profile processing equipment also includes at least a feeding area and a unloading area. The profile workpiece is sent from the feeding area to the sawing area for processing and then sent to the unloading area for unloading. The support fixture includes a Z-axis clamping module, which is set on the side of the 90-degree saw blade and is used to clamp the profile workpiece when the 90-degree saw blade cuts through.

[0007] And a Y-axis drive module, which is connected to the Z-axis clamping module to drive the Z-axis clamping module to extend and retract in the Y-axis direction.

[0008] This application provides a retractable support fixture for milling up to 90 degrees. By incorporating this retractable support fixture, stable support and clamping can be provided when the profile workpiece is being sawn at 90 degrees, ensuring machining accuracy and stability. The retractable design of the fixture allows it to flexibly adapt to profile workpieces of different sizes and shapes, improving the versatility of the equipment and production efficiency.

[0009] Furthermore, this application also proposes that the Z-axis clamping module includes a Z-axis cylinder and a first clamping block, the first clamping block extending or retracting with the movement of the Z-axis cylinder.

[0010] This application provides a telescopic support fixture for milling to 90 degrees. Through the cooperation of a Z-axis cylinder and a first clamping block, the Z-axis clamping module can achieve a simple structure and reliable clamping function. Using a cylinder as the driving element not only has the advantages of fast response and sensitive action, but also makes it easy to achieve air pressure control and adjustment. It can flexibly adjust the clamping force according to different processing requirements, further improving the practicality and adaptability of the support fixture.

[0011] Furthermore, this application also proposes that it further includes a guide post connected to the first clamping block, so that the first clamping block moves along the Z-axis direction.

[0012] The telescopic support fixture provided in this application, when milling to 90 degrees, uses the precise guidance of the guide column to make the telescopic movement of the first clamping block more stable and reliable, avoiding movement deviation and jamming. This ensures that the Z-axis clamping module can accurately and reliably clamp and release the profile workpiece, further improving the overall performance and machining accuracy of the support fixture.

[0013] Furthermore, this application also proposes that the Y-axis drive module includes a cylinder tilted at a 90-degree angle to the side of the saw blade.

[0014] This application provides a telescopic support fixture for milling to 90 degrees. It uses a cylinder tilted on the side of the 90-degree saw blade as the power source for the Y-axis drive module 203. This not only meets the drive requirements of the Z-axis clamping module, but also fully considers the spatial layout characteristics of the sawing area, making the overall structure of the support fixture more compact and reasonable.

[0015] Furthermore, this application also proposes that it further includes a mounting base and a connector, with one end of the cylinder connected to the mounting base and the other end connected to the connector.

[0016] This application provides a retractable support fixture for milling to 90 degrees. Through the cooperation of a mounting base and a connector, a cylinder can be reliably connected to the profile processing equipment and the Z-axis clamping module, forming a complete drive system. The mounting base provides stable support for the cylinder, ensuring its installation accuracy and operational stability; the connector effectively transmits the cylinder's driving force, achieving precise control of the Z-axis clamping module. This connection method is not only simple in structure and easy to assemble, but also ensures that the cylinder is subjected to uniform force and moves smoothly during operation, improving the reliability and service life of the Y-axis drive module.

[0017] Furthermore, this application also proposes that the Y-axis drive module further includes a Y-axis slide rail, and the connector is slidably mounted on the Y-axis slide rail.

[0018] Furthermore, this application also proposes to include a second clamping block, which is fixedly disposed on the front side of the connector and moves with the sliding of the connector without interfering with the first clamping block.

[0019] This application provides a retractable support fixture and profile processing equipment for milling to 90 degrees. By adding a second clamping block and having it work in conjunction with the first clamping block, the support fixture of this application achieves bidirectional clamping, significantly improving the clamping stability and reliability of the profile workpiece. Compared with a single-sided clamping structure, bidirectional clamping can more effectively disperse the clamping force, reduce workpiece deformation, and improve clamping rigidity, thereby providing more stable support for 90-degree sawing and further improving the accuracy and quality of profile processing.

[0020] Furthermore, this application also proposes that the connector is equipped with a workpiece detection sensor.

[0021] Furthermore, this application also proposes that the surfaces of the first clamping block and the second clamping block that contact the profile workpiece are provided with anti-slip textures or coatings.

[0022] Secondly, this application provides a profile processing equipment, which is equipped with a telescopic support fixture as described above for milling to 90 degrees.

[0023] The profile processing equipment is also equipped with a feeding device for transporting profile workpieces along the X-axis direction;

[0024] The sawing area is equipped with a sawing device, including at least one 90-degree saw blade, which is used to saw the profile workpiece to a set length. The 90-degree saw blade cuts along the Y-axis direction, perpendicular to the transport direction of the profile workpiece.

[0025] Beneficial effects: This application provides an additional clamp on the side of the 90-degree saw blade that can extend and retract along the Z-axis. When the 90-degree saw blade cuts, it extends to clamp the profile, providing auxiliary support and fixation, reducing the amount of workpiece deformation during processing, and improving processing accuracy.

Detailed Implementation

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. 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.

[0030] 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.

[0031] In the field of profile processing technology, profile processing equipment is widely used to achieve efficient and precise processing of various profiles. The sawing process is crucial in profile processing, especially when precise 90-degree sawing is required, where stability and accuracy are paramount. However, in traditional profile processing equipment, particularly when using a 90-degree saw for milling, unstable profile clamping is a common problem. This is because existing clamps are typically positioned far from the 90-degree saw, resulting in an excessively long lever arm acting on the profile during sawing, causing vibration or displacement and severely impacting processing accuracy and quality. To address these issues, this application proposes a retractable support clamp for 90-degree milling. Its innovative retractable clamp structure effectively solves the technical problem of unstable profile clamping during 90-degree sawing, significantly improving the accuracy and stability of profile processing.

[0032] To address this problem, this application proposes a retractable support fixture for milling to 90 degrees, which is mainly used in the sawing zone 200 of profile processing equipment. Figure 1As shown, a typical profile processing equipment usually includes a feeding area 100, a sawing area 200, and an unloading area 300. The profile workpiece first enters from the feeding area 100, is processed in the sawing area 200, and finally reaches the unloading area 300 for unloading. The support fixture of this application is set in the sawing area 200, specifically, it is set on the side of the 90-degree saw blade 202 in the sawing area 200. The core components of this support fixture include a Z-axis clamping module 201 and a Y-axis drive module 203. The main function of the Z-axis clamping module 201 is to clamp and fix the profile workpiece during milling by the 90-degree saw blade 202 to provide stable support force; the Y-axis drive module 203 is responsible for driving the Z-axis clamping module 201 to extend and retract in the Y-axis direction to realize the extension and retraction function of the fixture.

[0033] Specifically, the Z-axis clamping module 201 is innovatively positioned on the side of the 90-degree saw blade 202. This arrangement is one of the key features of this application. Unlike the prior art where the clamp is positioned far from the 90-degree saw blade 202, this application positions the Z-axis clamping module 201 close to the 90-degree saw blade 202, minimizing the distance between the clamp and the saw blade, thereby effectively reducing the lever arm length during processing. When the 90-degree saw blade 202 mills the profile workpiece, the Z-axis clamping module 201 can extend in time to apply clamping force to the profile workpiece, providing close-range support and preventing vibration or displacement of the profile workpiece. As one possible implementation, the Z-axis clamping module 201 can take various forms, such as a cylinder, hydraulic cylinder, or motor-driven gripper. For example, a pneumatic gripper can be used, with the opening and closing of the gripper controlled by air pressure, thereby achieving clamping and releasing of the profile workpiece.

[0034] The Y-axis drive module 203 is connected to the Z-axis clamping module 201, and its main function is to drive the Z-axis clamping module 201 to extend and retract in the Y-axis direction. This extension and retraction function allows the support fixture to function at different times according to processing needs. Before the 90-degree saw blade 202 performs milling, the Y-axis drive module 203 can drive the Z-axis clamping module 201 to retract, without hindering the normal feeding and positioning of the profile workpiece. When the 90-degree saw blade 202 begins milling, the Y-axis drive module 203 drives the Z-axis clamping module 201 to extend, bringing it close to the profile workpiece and clamping it for support, ensuring the stability of the sawing process. After processing, the Y-axis drive module 203 drives the Z-axis clamping module 201 to retract again, facilitating the removal of the profile workpiece and subsequent processing. There are several ways to implement the Y-axis drive module 203, such as using a cylinder, lead screw, or rack and pinion mechanism. Considering response speed and control accuracy, cylinder drive is a preferred solution.

[0035] Compared with existing technologies, the retractable support fixture proposed in this application has significant technical advantages. In traditional profile processing equipment, the fixture is located beside the 45-degree saw blade, typically far from the 90-degree saw blade 202. This results in relatively weak support from the fixture when sawing profiles at 90 degrees, making it difficult to effectively suppress vibration and displacement of the profiles. However, this application addresses this by placing the Z-axis clamping module 201 on the side of the 90-degree saw blade 202 and utilizing the Y-axis drive module 203 to achieve the retractable function of the fixture. This allows the support fixture to function at the most critical moments and locations, greatly improving the stability of 90-degree sawing. This innovative structural design effectively overcomes the shortcomings of existing technologies, providing a reliable guarantee for improving the accuracy and quality of profile processing.

[0036] Combination Figure 1 and Figure 2 As shown, when the profile workpiece is conveyed from the feeding area 100 to the sawing area 200, it is first precisely positioned by a positioning device (not shown in the figure). Before the 90-degree saw blade 202 begins milling the profile workpiece, the Y-axis drive module 203 drives the Z-axis clamping module 201 to a retracted state, at which point the Z-axis clamping module 201 does not obstruct the normal sawing of the profile workpiece. When the 90-degree saw blade 202 starts and begins milling, the control system sends a signal to drive the Y-axis drive module 203 to extend along the Y-axis direction, causing it to quickly move to a predetermined position close to the profile workpiece. Then, the Z-axis clamping module 201 extends in the Z-axis direction; for example, the Z-axis cylinder 204 pushes the first clamping block 205 to extend, applying clamping force to the profile workpiece and providing stable support. Under the action of the Z-axis clamping module 201, the profile workpiece is firmly clamped in place, effectively suppressing vibrations and displacements that may occur during the milling process of the 90-degree saw blade 202. After the milling is completed, the Z-axis clamping module 201 first retracts in the Z-axis direction to release the clamping force on the profile workpiece. Then, the Y-axis drive module 203 drives the Z-axis clamping module 201 to retract back to its initial position along the Y-axis direction, preparing for the subsequent removal of the workpiece. The processed profile workpiece is then transported to the unloading area 300. Through the above working process, the retractable support fixture of this application provides stable and reliable support at the critical moment of 90-degree sawing, significantly improving the accuracy and efficiency of profile processing.

[0037] Furthermore, this application also proposes that the Z-axis clamping module 201 includes a Z-axis cylinder 204 and a first clamping block 205, the first clamping block 205 extending or retracting with the movement of the Z-axis cylinder 204.

[0038] The Z-axis clamping module 201 is a key component for clamping and supporting profile workpieces. For example... Figure 2As shown, in a preferred embodiment, the Z-axis clamping module 201 mainly consists of a Z-axis cylinder 204 and a first clamping block 205. The Z-axis cylinder 204 serves as the power actuator, responsible for driving the first clamping block 205 to perform telescopic movements, thereby achieving clamping and releasing actions. The first clamping block 205 is the clamping component that directly contacts the profile workpiece; its shape and material can be selected and designed according to the characteristics of the actual workpiece.

[0039] Specifically, the Z-axis cylinder 204 is a common linear motion cylinder. Its working principle is to use compressed air to drive the piston to perform linear reciprocating motion within the cylinder. In this embodiment, the Z-axis cylinder 204 is fixedly installed at an appropriate position on the support fixture, and its piston rod is connected to the first clamping block 205. When it is necessary to clamp the profile workpiece, the control system supplies air to the Z-axis cylinder 204. The compressed air pushes the piston rod to extend, thereby moving the first clamping block 205 closer to the profile workpiece until the first clamping block 205 contacts the profile workpiece and applies sufficient clamping force, firmly fixing the profile workpiece in place. When it is necessary to release the fixture, the control system controls the Z-axis cylinder 204 to exhaust air. The piston rod retracts under the action of the return spring or air pressure, driving the first clamping block 205 to retract, releasing the clamping of the profile workpiece. The design of the first clamping block 205 can be adjusted according to the shape of the profile workpiece and the clamping requirements. For example, to increase the contact area with the profile workpiece and improve clamping stability, the surface of the first clamping block 205 in contact with the profile workpiece can be set as a flat surface, an arc surface, or a friction surface with teeth. In addition, the material of the first clamping block 205 can be selected as a wear-resistant and non-slip material, such as rubber, polyurethane, or specially treated metal materials, to ensure the reliability and service life of clamping.

[0040] Therefore, through the cooperation of the Z-axis cylinder 204 and the first clamping block 205, the Z-axis clamping module 201 can achieve a clamping function with a simple structure and reliable operation. Using a cylinder as the driving element not only has the advantages of fast response speed and sensitive operation, but also makes it easy to realize air pressure control and adjustment, and can flexibly adjust the clamping force according to different processing requirements, further improving the practicality and adaptability of the support fixture.

[0041] Furthermore, this application also proposes to include a guide post 206 connected to the first clamping block 205, so that the first clamping block 205 moves along the Z-axis direction.

[0042] To ensure the stability and accuracy of the first clamping block 205 during its telescopic movement and to prevent offset or rotation, this application further includes a guide post 206 in the Z-axis clamping module 201. Figure 2As shown, the guide post 206 is connected to the first clamping block 205. Its main function is to guide and constrain the movement trajectory of the first clamping block 205 so that it always moves precisely along the predetermined Z-axis direction.

[0043] Specifically, the guide post 206 can be a smooth cylindrical rod, typically made of wear-resistant, high-strength metal or engineering plastic. In the structural design of the Z-axis clamping module 201, a guide hole or guide sleeve can be provided to mate with the guide post 206, and the first clamping block 205 is connected to the guide post 206. Thus, when the Z-axis cylinder 204 drives the first clamping block 205 to extend or retract, the guide post 206 provides guidance, ensuring that the first clamping block 205 always moves linearly along the Z-axis direction without deviation or jamming. As an example, the guide post 206 can be fixed to the cylinder body of the Z-axis cylinder 204 and positioned parallel to the piston rod of the Z-axis cylinder 204. The first clamping block 205 can be designed as a sleeve, fitted onto the guide post 206, and slidingly engaged with the guide post 206 through friction-reducing elements such as bearings or bushings. In another embodiment, two or more parallel guide posts 206 can be provided to improve the stability and reliability of the guide. The guide posts 206 are fixedly connected to the first clamping block 205, and the Z-axis cylinder 204 is provided with a guide hole or guide sleeve, which is slidably connected to the guide posts 206. In addition, in order to prevent dust or debris from entering the guide mechanism and affecting the guide effect and service life, a sealing device, such as a dust cover or sealing ring, can be provided at the sliding part of the guide post 206.

[0044] Therefore, the guide post 206 effectively improves the motion accuracy and stability of the Z-axis clamping module 201. Through the precise guiding action of the guide post 206, the extension and retraction of the first clamping block 205 is smoother and more reliable, avoiding motion deviations and jamming. This ensures that the Z-axis clamping module 201 can accurately and reliably clamp and release the profile workpiece, further enhancing the overall performance and machining accuracy of the support fixture. Compared to a structure without a guide post, the design using the guide post 206 significantly improves the operational reliability and service life of the Z-axis clamping module 201.

[0045] Furthermore, this application also proposes that the Y-axis drive module 203 includes a cylinder 207 tilted to the side of the 90-degree saw blade 202.

[0046] The Y-axis drive module 203 is a key actuator that enables the Z-axis clamping module 201 to extend and retract in the Y-axis direction. For example... Figure 2As shown, as a preferred solution with a compact structure and fast response, the Y-axis drive module 203 can use a cylinder 207 as a power source. In order to better adapt to the spatial layout of the sawing area 200 and realize the precise telescopic movement of the Z-axis clamping module 201, the cylinder 207 is innovatively tilted and set on the side of the 90-degree saw blade 202.

[0047] Specifically, cylinder 207 is a linear motion cylinder, and its working principle is similar to that of the aforementioned Z-axis cylinder 204, also using compressed air to drive the piston rod to make linear motion. Unlike the Z-axis cylinder 204, cylinder 207 in the Y-axis drive module 203 is not vertically or horizontally positioned, but rather installed at an angle relative to the horizontal or vertical plane on the side of the 90-degree saw blade 202. This inclined arrangement fully considers the structural characteristics and space constraints of the sawing area 200. Since the 90-degree saw blade 202 typically has a large diameter, the space around it is relatively small. If a horizontally or vertically arranged drive mechanism were used, it might occupy too much space, affecting the overall layout and operability of the equipment. The inclined cylinder 207, however, can be more flexibly arranged on the side of the 90-degree saw blade 202, making full use of limited space resources and making the structure of the Y-axis drive module 203 more compact. As an example, the tilt angle of cylinder 207 can be adjusted according to the actual structural design and space requirements; for example, it can be set to an angle of 30 to 60 degrees with the horizontal plane. The cylinder body of cylinder 207 can be fixed to the frame or other support structure by mounting base 208, and its piston rod is connected to connector 209. Through the extension and retraction of piston rod, connector 209 and Z-axis clamping module 201 connected thereto can be driven to perform precise extension and retraction in the Y-axis direction.

[0048] Therefore, using a cylinder 207 tilted to the side of the 90-degree saw blade 202 as the power source for the Y-axis drive module 203 not only meets the drive requirements of the Z-axis clamping module 201, but also fully considers the spatial layout characteristics of the sawing area 200, making the overall structure of the support fixture more compact and reasonable. Compared with other drive methods, cylinder drive also has advantages such as fast response speed, sensitive action, and easy control, which can better meet the performance requirements of profile processing equipment for support fixtures.

[0049] Furthermore, this application also proposes that one end of the cylinder 207 is connected to the mounting base 208, and the other end is connected to the connector 209.

[0050] To achieve effective connection and force transmission between cylinder 207 and other components, this application has specifically designed the connection method of cylinder 207 in the Y-axis drive module 203. For example... Figure 2As shown, one end of the cylinder 207 is connected to the mounting base 208, and the other end is connected to the connector 209. Through the mounting base 208 and the connector 209, the cylinder 207 can be stably installed on the profile processing equipment and effectively drive the Z-axis clamping module 201 to perform telescopic movements.

[0051] Specifically, the main function of the mounting base 208 is to provide a fixed mounting platform for the cylinder 207. The mounting base 208 can be a component with a certain structural strength, and its material is usually a metal, such as steel or aluminum alloy. The mounting base 208 can be fixed to the frame or other supporting structure of the profile processing equipment by bolts, welding, or other connection methods, ensuring that the cylinder 207 will not loosen or shift during operation. Mounting holes or mounting surfaces matching the cylinder body of the cylinder 207 can be provided on the mounting base 208, and the cylinder 207 is fixed to the mounting base 208 by bolts or other fasteners. The connecting piece 209 is mainly used to connect the piston rod of the cylinder 207 and the Z-axis clamping module 201. The connecting piece 209 is also usually made of metal, possessing a certain strength and rigidity, and can effectively transmit the driving force of the cylinder 207. One end of the connector 209 is connected to the piston rod of the cylinder 207, for example, by means of threaded connection, pin connection or flange connection; the other end is connected to the Z-axis clamping module 201, for example, it can be directly connected to the support structure of the Z-axis clamping module 201. The Z-axis clamping module 201 can be fixed to the front end of the connector 209 by screws, or it can be connected by other intermediate components.

[0052] Therefore, through the combined use of the mounting base 208 and the connector 209, the cylinder 207 can be reliably connected to the profile processing equipment and the Z-axis clamping module 201, forming a complete drive system. The mounting base 208 provides a stable support for the cylinder 207, ensuring the installation accuracy and working stability of the cylinder 207; the connector 209 effectively transmits the driving force of the cylinder 207, realizing precise control of the Z-axis clamping module 201. This connection method is not only simple in structure and easy to assemble, but also ensures that the cylinder 207 is subjected to uniform force and moves smoothly during operation, improving the reliability and service life of the Y-axis drive module 203.

[0053] Furthermore, this application also proposes that the Y-axis drive module 203 further includes a Y-axis slide rail 210, and the connector 209 is slidably disposed on the Y-axis slide rail 210.

[0054] To further improve the motion accuracy and stability of the Y-axis drive module 203, this application innovatively introduces a Y-axis slide rail 210 into the Y-axis drive module 203. For example... Figure 2As shown, the Y-axis slide rail 210 works in conjunction with the connector 209 to provide precise guidance and support for the sliding movement of the connector 209 in the Y-axis direction.

[0055] Specifically, the Y-axis slide rail 210 is a common linear guide assembly, typically consisting of a slide rail body and a slider. The slide rail body is elongated, possessing precise straightness and a guiding surface, and is usually made of high-strength, wear-resistant metal materials, such as bearing steel or alloy steel. The slider cooperates with the slide rail body, allowing for low-friction, high-precision linear sliding motion on the slide rail body. In this embodiment, the slide rail body of the Y-axis slide rail 210 can be fixed to the frame of the support fixture or other support structure, for example, mounted on the mounting base 208, arranged parallel to the Y-axis direction of the 90-degree saw blade 202. The connecting piece 209 can be mounted on the slider, allowing it to slide on the slide rail body of the Y-axis slide rail 210, or the connecting piece 209 itself can have a sliding structure that cooperates with the slide rail body of the Y-axis slide rail 210. When the cylinder 207 drives the connecting member 209 to move, the Y-axis slide rail 210 guides the connecting member 209 to slide smoothly and precisely along the Y-axis direction, preventing the connecting member 209 from shaking, deviating, or jamming during movement, thus ensuring the accuracy and stability of the Y-axis telescopic movement of the Z-axis clamping module 201. As a preferred structural form, the Y-axis slide rail 210 can be selected from ball linear guides or roller linear guides. These guides have advantages such as low friction coefficient, high motion accuracy, and strong load-bearing capacity, which can better meet the performance requirements of the profile processing equipment for the Y-axis drive module 203.

[0056] Therefore, the introduction of the Y-axis slide rail 210 effectively improves the overall performance of the Y-axis drive module 203. Through the precise guiding effect of the Y-axis slide rail 210, the Y-axis movement of the connector 209 is more stable and smooth, significantly improving movement accuracy and repeatability. This ensures that the Z-axis clamping module 201 can move accurately and reliably to the predetermined position, providing stable and reliable support for 90-degree sawing, and further improving the accuracy and quality of profile processing.

[0057] Furthermore, this application also proposes to include a second clamping block 211, which is fixedly disposed on the front side of the connector 209 and moves with the sliding of the connector 209, without interfering with the first clamping block 205.

[0058] To further improve the clamping stability and reliability of the support fixture for profile workpieces, this application adds a second clamping block 211 to the support fixture. Figure 2As shown, the second clamping block 211 is fixedly disposed on the front side of the connector 209, and slides together with the connector 209 as a whole with the Y-axis slide rail 210. The second clamping block 211, together with the aforementioned first clamping block 205, forms a two-way clamping structure, which can apply clamping force from both sides of the profile workpiece simultaneously, thereby achieving a more stable and reliable clamping effect.

[0059] Specifically, the second clamping block 211 is fixed to the front side of the connector 209. "Front side" refers to its position relative to the 90-degree saw blade 202; that is, the second clamping block 211 is located on the side of the connector 209 closest to the 90-degree saw blade 202 where the sawing operation takes place. Since the connector 209 is a component of the Y-axis drive module 203, its sliding movement in the Y-axis direction directly drives the second clamping block 211 to move synchronously. In the structural design of the support fixture, it is necessary to ensure that the movement trajectory of the second clamping block 211 matches the movement trajectory of the first clamping block 205, so that both can form an effective clamping force when clamping the workpiece, while simultaneously avoiding mutual interference and collisions. To achieve better clamping effect, the shape and size of the first clamping block 205 and the second clamping block 211 can be customized according to the cross-sectional shape of the profile workpiece. For example, for a profile workpiece with a rectangular cross-section, the first clamping block 205 and the second clamping block 211 can adopt a planar clamping surface; for a profile workpiece with a circular cross-section, an arc-shaped clamping surface can be adopted to improve the clamping stability and contact area.

[0060] Therefore, by adding a second clamping block 211 and having it work in conjunction with the first clamping block 205, the support fixture of this application achieves bidirectional clamping, significantly improving the clamping stability and reliability of the profile workpiece. Compared to a single-sided clamping structure, bidirectional clamping can more effectively disperse the clamping force, reduce workpiece deformation, and improve clamping rigidity, thereby providing more stable support for 90-degree sawing and further improving the accuracy and quality of profile processing.

[0061] Furthermore, this application also proposes that the connector 209 is equipped with a workpiece detection sensor.

[0062] To achieve intelligent control and automated operation of the support fixture and further improve the processing efficiency of profile processing equipment, this application innovatively sets a workpiece detection sensor on the connector 209. The workpiece detection sensor, installed on the connector 209, primarily functions to detect in real time whether the profile workpiece is in position and feeds the detection signal back to the control system, thereby realizing automatic control of the support fixture.

[0063] Specifically, a workpiece detection sensor is a sensor device capable of detecting the presence or absence of an object. Depending on the detection principle, workpiece detection sensors can be of various types, such as proximity sensors, photoelectric sensors, and laser sensors. As a commonly used preferred option, proximity sensors, such as inductive or capacitive proximity sensors, can be used. These sensors feature non-contact detection, do not damage the surface of the profile workpiece, and have high reliability and anti-interference capabilities. During installation, the workpiece detection sensor can be fixed at an appropriate position on the connector 209, ensuring its detection area covers the expected position of the profile workpiece. For example, the workpiece detection sensor can be installed on the side of the connector 209 near the 90-degree saw blade 202, with its detection direction facing the feeding direction of the profile workpiece. When the profile workpiece is conveyed to the sawing area 200 by the feeding device and reaches the predetermined processing position, the workpiece detection sensor can immediately detect the presence of the profile workpiece and generate a detection signal. The detection signal is transmitted to the control system of the profile processing equipment. Based on the received signal, the control system determines that the profile workpiece is in place and controls the Y-axis drive module 203 and the Z-axis clamping module 201 to perform the corresponding clamping actions, starting the sawing process. After processing is completed, the control system can also determine whether the profile workpiece has been removed based on the signal from the workpiece detection sensor and control the support fixture to reset, preparing for the next processing.

[0064] Therefore, by setting a workpiece detection sensor on the connector 209, the support fixture of this application has an automatic workpiece detection function, realizing intelligent control of the support fixture. Compared with manual operation or time-series control, the use of a workpiece detection sensor can more accurately and timely control the movement of the support fixture, avoiding processing errors or equipment idling caused by the workpiece not being in place or not being in place accurately. This significantly improves the automation level and processing efficiency of profile processing equipment, and reduces the labor intensity and risk of misoperation of manual operation.

[0065] Furthermore, this application also proposes that the surfaces of the first clamping block 205 and the second clamping block 211 that contact the profile workpiece are provided with anti-slip textures or coatings.

[0066] To further improve the reliability and stability of the support fixture in clamping the profile workpiece and prevent slippage during clamping, this application optimizes the structure of the first clamping block 205 and the second clamping block 211, and applies anti-slip textures or coatings to their surfaces in contact with the profile workpiece. Figure 2 As shown, by adding anti-slip measures to the surface of the clamping block, the friction between the clamping block and the profile workpiece can be effectively increased, thereby improving the reliability and stability of clamping.

[0067] Specifically, the "anti-slip texture" can be achieved by machining various micro-geometric shapes, such as grid patterns, sawtooth patterns, diamond patterns, or raised dot arrays, onto the surfaces of the first clamping block 205 and the second clamping block 211 that contact the profile workpiece. These texture structures can increase the roughness of the contact surfaces, thereby increasing the coefficient of friction and enhancing the clamping force. The anti-slip texture can be processed using various methods such as machining, laser processing, etching, or molding, with the appropriate method selected based on the material and processing requirements. For example, for metal clamping blocks, fine anti-slip textures can be produced using mechanical engraving or laser marking; for rubber or plastic clamping blocks, the predetermined anti-slip texture can be directly created during mold forming. The "anti-slip coating" is a layer of special material with a high coefficient of friction applied to the surfaces of the first clamping block 205 and the second clamping block 211 that contact the profile workpiece. Commonly used anti-slip coating materials include rubber coatings, polyurethane coatings, friction-enhancing coatings, or ceramic coatings. These coating materials typically possess a high coefficient of friction and good wear resistance, effectively increasing the friction on the clamping block surface and enhancing the clamping effect. Anti-slip coatings can be applied using various methods such as spraying, brushing, dipping, or chemical deposition. The appropriate coating method and thickness should be selected based on the specific coating material and the operating environment. For example, in applications requiring high clamping forces, a thicker polyurethane coating can be applied to achieve better anti-slip performance and wear resistance.

[0068] Therefore, by providing anti-slip textures or coatings on the contact surfaces of the first clamping block 205 and the second clamping block 211, the support fixture of this application effectively increases the friction between the clamping blocks and the profile workpiece, significantly enhancing the reliability and stability of clamping. This anti-slip design effectively prevents the profile workpiece from slipping or shifting during sawing due to insufficient clamping force or vibration, ensuring the accuracy and quality of profile processing and further improving the practicality and processing effect of the support fixture.

[0069] Secondly, this application also proposes a profile processing equipment, which is equipped with a telescopic support fixture for milling to 90 degrees as described above; the profile processing equipment is also equipped with a feeding device for transporting profile workpieces along the X-axis direction; the sawing zone 200 is equipped with a sawing device, including at least one 90-degree saw blade 202 for sawing the profile workpieces to a set length, the 90-degree saw blade 202 sawing along the Y-axis direction, perpendicular to the transport direction of the profile workpieces.

[0070] The core improvement of this equipment lies in its innovative integration of the retractable support fixture for milling to 90 degrees, as described in detail in the aforementioned embodiments. For example... Figure 1As shown, the profile processing equipment mainly includes functional areas such as a feeding area 100, a sawing area 200, and an unloading area 300, as well as a feeding device for conveying profile workpieces between the areas and a sawing device for performing sawing operations. The innovation of this application lies in the fact that, in the sawing area 200, particularly at the processing position of the 90-degree saw blade 202, a retractable support clamp as described above is configured, thereby effectively solving the problem of unstable profile clamping during 90-degree sawing in the prior art and improving the overall performance of the profile processing equipment.

[0071] Specifically, the main function of the feeding device is to transport the profile workpiece from the feeding area 100 to the sawing area 200 along the X-axis direction, ensuring stable feeding of the profile workpiece during processing. The feeding device can take various forms, such as roller conveyor mechanisms, chain conveyor mechanisms, belt conveyor mechanisms, or robotic arms, selecting the appropriate feeding method based on factors such as the size, weight, and processing cycle of the profile workpiece. The sawing area 200 is the core working area of ​​the profile processing equipment, where a sawing device is installed for sawing the profile workpiece. The sawing device includes at least one 90-degree saw blade 202 for achieving a 90-degree sawing perpendicular to the profile workpiece's transport direction. In some embodiments, the sawing device may also include saw blades of other angles, such as a 45-degree saw blade, to achieve complex multi-angle sawing. The sawing direction of the 90-degree saw blade 202 is the Y-axis direction, perpendicular to the profile workpiece's transport direction (X-axis direction). Through the rotational cutting action of the 90-degree saw blade 202, the profile workpiece is sawn to a preset length. The key improvement of this application lies in the provision of the aforementioned retractable support fixture at the 90-degree saw blade 202 processing position in the sawing zone 200. This support fixture can promptly extend the Z-axis clamping module 201 to clamp and support the profile workpiece during milling operations performed by the 90-degree saw blade 202, effectively improving the stability of 90-degree sawing, reducing processing vibration and displacement, and ensuring sawing accuracy.

[0072] Therefore, the profile processing equipment provided in this application, through the innovative integration of a retractable support clamp, achieves stable clamping and precise processing during 90-degree sawing, effectively improving the overall performance and processing quality of the equipment. This profile processing equipment can be widely used in the precision sawing of various profiles such as aluminum, plastic, and wood profiles, and has significant application value and market prospects.

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.
