Description

Technical Field

[0001] This invention relates to the field of milling tool technology, specifically to a quick clamping fixture for milling based on a linear module base. Background Technology

[0002] In industrial production, the milling of linear module bases is one of the key processes, and the clamping method has a significant impact on processing efficiency and quality. Traditional clamping methods often have many drawbacks. For example, most methods use three-jaw chucks for clamping, which can only apply fixing force to the base from a limited number of sides or points. This results in a time-consuming and labor-intensive clamping process, making it difficult to achieve efficient clamping operations. Furthermore, the clamping stability is poor. During milling, the base is easily displaced, vibrated, or even deformed by cutting forces, which greatly affects the machining accuracy and makes it difficult to meet the requirements of high-precision machining. At the same time, traditional tooling has poor versatility and is difficult to adapt to linear module bases of different specifications and sizes. Each time the base specifications are changed, a lot of time is required to reset the tooling parameters and structure, which greatly increases production downtime and reduces overall production efficiency.

[0003] With the development of the manufacturing industry, the requirements for processing accuracy, efficiency and tooling versatility are increasing. Existing clamping technology can hardly meet the market's comprehensive demands for high precision, high efficiency and flexibility in the processing of linear module bases. Therefore, those skilled in the art have proposed a rapid clamping fixture based on the milling of linear module bases to solve the above problems. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a quick clamping fixture based on the milling of linear module bases, thus solving the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a quick-clamping fixture based on the milling of a linear module base, comprising a mounting base, a mounting frame mounted on the top of the mounting base via a disassembly assembly, an electric telescopic rod I fixedly connected to the outer side of the mounting frame, a movable plate fixedly connected to the output end of the electric telescopic rod I, cranks hinged to both the upper and lower ends of the movable plate, two sets of mounting seats fixedly connected to the inner side of the mounting frame, a rotating rod rotatably mounted on the inner side of each set of mounting seats, multiple connecting arms fixedly connected to the outer side of the rotating rod, a support frame fixedly connected to the end of each connecting arm, connecting shafts fixedly connected to multiple through holes at the top of the support frame, a support plate I rotatably connected to the bottom end of each connecting shaft, an electric telescopic rod II fixedly connected to the inner side of the mounting frame, and a support plate II fixedly connected to the output end of the electric telescopic rod II.

[0006] Through the above technical solution, the mounting bracket can be quickly installed or removed from the mounting floor by disassembling and assembling the components; by using the linkage of components such as the electric telescopic rod one, movable plate, crank, rotating rod, connecting arm, support frame, connecting shaft and support plate one, the upper and lower sides of the base can be clamped efficiently; the left side of the base is clamped by the electric telescopic rod two and support plate two, and the right side of the base is clamped by the rotating shaft on the outside of the support frame, thereby achieving rapid and stable clamping of the four sides of the base, improving the efficiency and accuracy of milling.

[0007] Preferably, the disassembly and assembly assembly includes a connecting plate installed at the bottom of the mounting frame. Two limiting plates are fixedly connected to the bottom of the connecting plate, and the limiting plates have insertion holes inside. Two fixing plates are fixedly connected to the top of the mounting floor. A drive screw is threadedly connected to the through hole on the outside of the fixing plate. A movable rod is fixedly connected to the outside of the drive screw. Mounting grooves are opened on both the left and right sides inside the fixing plate. Two movable rods are slidably installed inside the fixing plate. Insert blocks are fixedly connected to the ends of the two movable rods that are far apart from each other.

[0008] Through the above technical solution, by cooperating with components such as connecting plate, limiting plate, insertion hole, fixing plate, drive screw, movable rod one, and insertion block, rotating the drive screw can cause the insertion block on the movable rod one to insert or exit the insertion hole on the limiting plate, thereby completing the quick installation or disassembly of the mounting bracket and improving the efficiency and convenience of tooling assembly and disassembly.

[0009] Preferably, the shape of the plug matches the shape of the socket, and one end of the plug is inserted into the interior of the socket.

[0010] The above technical solution ensures that the insert block can be accurately inserted into the socket, achieving a stable connection between the mounting bracket and the fixing plate, thereby guaranteeing the stability of the tooling during clamping and processing. Simultaneously, this matching fit facilitates quick insertion and removal, improving assembly and disassembly efficiency.

[0011] Preferably, the fixed plate has a limiting groove inside, and both movable rods are slidably installed inside the limiting groove.

[0012] The above technical solution restricts the sliding trajectory of the movable rod by limiting the groove, ensuring that it can only slide stably in a predetermined direction, thereby effectively preventing the movable rod from deviating or getting stuck during the movement, and ensuring the normal operation and reliability of the assembly and disassembly components.

[0013] Preferably, the two movable rods are elastically connected by a spring, and the near ends of the two movable rods are provided with a conical surface, and the end of the movable rod away from the drive screw is also provided with a conical surface.

[0014] Through the above technical solution, the spring elastically connects the movable rod one, allowing the two to move away from or towards each other under external force, and automatically reset after the external force disappears. The conical surface design facilitates the sliding of the movable rod one by the movable rod two, enabling the insertion or disengagement of the insert block from the insertion hole, ensuring convenient and flexible assembly and disassembly.

[0015] Preferably, the two fixing plates correspond one-to-one with the connecting plates at corresponding positions, and the driving screw passes through the outer side of the fixing plate and extends to its exterior.

[0016] The above technical solution ensures precise alignment between the fixed plate and the connecting plate. The drive screw passes through the fixed plate and extends to the outside, making it easy to control the rotation of the internal movable rod two by rotating the drive screw, thereby driving the movable rod one and the insert block to move, and realizing the quick assembly and disassembly of the mounting bracket.

[0017] Preferably, the outer side of the support frame is rotatably connected to multiple rotating shafts, which are used to support the sides of the linear module base.

[0018] The above technical solution involves setting multiple rotatable shafts on the outside of the support frame to support the linear module base from the side, thereby enhancing clamping stability, preventing the base from tipping over during processing, and ensuring processing accuracy.

[0019] Preferably, the outer sides of the two cranks are fixedly connected to one end of the rotating rod at the corresponding position, and rubber pads are provided on the outer sides of both the first support plate and the second support plate.

[0020] Through the above technical solution, the crank and the rotating rod are fixedly connected to ensure stable power transmission, so that the rotating rod rotates synchronously with the crank to achieve precise clamping of the first support plate; the rubber pads on the outer side of the first and second support plates are used to protect the surface of the base, prevent damage during clamping, and enhance friction to ensure stable clamping.

[0021] This invention provides a quick-clamping fixture based on the milling of a linear module base. It offers the following advantages:

[0022] 1. This invention can fix the four sides of the linear module base, thereby greatly improving clamping efficiency and significantly shortening clamping time, while ensuring machining accuracy and meeting the requirements of high-precision machining. The four-sided fixing method enhances clamping stability, effectively preventing the base from shifting or deforming due to cutting forces during milling, ensuring a smooth machining process and improving machining quality. In addition, this fixture is highly versatile and can be quickly adjusted to adapt to linear module bases of various specifications and sizes.

[0023] 2. This invention, by adding disassembly and assembly components, enables rapid installation and disassembly of tooling, thus significantly improving production efficiency, reducing downtime caused by tooling changes, and making the milling process of the linear module base smoother and more efficient. Furthermore, this design enhances the versatility and flexibility of the tooling, allowing for rapid adaptation and adjustment to linear module bases of different specifications and models.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Please see the appendix Figure 1 -Appendix Figure 6This invention provides a quick clamping fixture based on the milling of a linear module base, including a mounting base 1. A mounting frame 2 is mounted on the top of the mounting base 1 via a disassembly assembly. An electric telescopic rod 9 is fixedly connected to the outer side of the mounting frame 2. A movable plate 14 is fixedly connected to the output end of the electric telescopic rod 9. Cranks 11 are hinged to both the upper and lower ends of the movable plate 14. Two sets of mounting seats 12 are fixedly connected to the inner side of the mounting frame 2. A rotating rod 4 is rotatably mounted on the inner side of each set of mounting seats 12. Multiple connecting arms 5 are fixedly connected to the outer side of the rotating rod 4. A support frame 6 is fixedly connected to the end of the connecting arm 5. A connecting shaft 7 is fixedly connected to multiple through holes at the top of the support frame 6. A support plate 8 is rotatably connected to the bottom end of the connecting shaft 7. An electric telescopic rod 15 is fixedly connected to the inner side of the mounting frame 2. A support plate 13 is fixedly connected to the output end of the electric telescopic rod 15.

[0033] Specifically, mounting floor 1 serves as the foundation for the tooling, supporting and installing other components to ensure overall stability. Mounting frame 2 serves as a mounting platform for other components, forming a clamping space to accommodate the linear module base. The output end of the electric telescopic rod 9 moves, causing the movable plate 14 to move synchronously, providing a power source for the subsequent swinging of crank 11 and rotation of rotating rod 4. Crank 11 converts the linear motion of movable plate 14 into the rotational motion of rotating rod 4, realizing the conversion of motion form. Mounting base 12 is used to install and support rotating rod 4, providing a fulcrum for the rotation of rotating rod 4. Rotating rod 4 is driven by crank 11 to rotate, thereby driving connecting arm 5 to swing, transmitting power to support frame 6 and support plate 8, realizing the clamping of the upper and lower sides of the linear module base. Support plate 8 is rotatably connected to support frame 6 through connecting shaft 7, and after being stressed, it adheres to the upper and lower sides of the linear module base, directly contacting the linear module base, providing clamping force, and realizing the fixation of the upper and lower sides of the base. Support plate 2 13 moves under the drive of electric telescopic rod 2 15 and fits against the left side of the linear module base, directly contacting the linear module base to complete the clamping and fixing of the left side of the base.

[0034] After placing the linear module base inside the mounting bracket 2, activate the electric telescopic rod 9. Its output end drives the movable plate 14 to move, which in turn causes the crank 11 to swing. The swing of the crank 11 drives the rotating rod 4 to rotate. The rotating rod 4, through the connecting arm 5 and the connecting shaft 7, drives the support plate 8 to fit against the upper and lower sides of the base. At the same time, the electric telescopic rod 15 pushes the support plate 13 to fit against the left side of the base, while the rotating shaft 10 is manually rotated to fit against the right side of the base, completing the clamping of the four sides of the base. This process is highly automated, has high clamping efficiency, short clamping time, and can ensure processing accuracy, meeting the requirements of high-precision processing.

[0035] The assembly includes a connecting plate 302 installed at the bottom of the mounting bracket 2. Two limiting plates 303 are fixedly connected to the bottom of the connecting plate 302. The limiting plates 303 have insertion holes 304 inside. Two fixing plates 301 are fixedly connected to the top of the mounting base 1. A drive screw 308 is threadedly connected to the through hole on the outer side of the fixing plate 301. A movable rod 307 is fixedly connected to the outside of the drive screw 308. Mounting grooves 309 are provided on both the left and right sides inside the fixing plate 301. Two movable rods 306 are slidably installed inside the fixing plate 301. Insert blocks 310 are fixedly connected to the ends of the two movable rods 306 that are far apart from each other. The shape of the insert blocks 310 matches the shape of the insertion holes 304, and one end of the insert blocks 310 is inserted into the interior of the insertion holes 304.

[0036] Specifically, the connecting plate 302 cooperates with the fixing plate 301 to achieve quick installation and disassembly of the mounting bracket 2. The insertion hole 304 is used to insert the insertion block 310, thereby fixing the mounting bracket 2. The fixing plate 301 provides a fixed base and connection point for the installation of the mounting bracket 2. The drive screw 308 is threaded to achieve linkage with the second movable rod 307; rotating the drive screw 308 controls the rotation of the second movable rod 307, thereby realizing the movement of the first movable rod 306 and the insertion block 310. The mounting groove 309 is formed inside the fixing plate 301 to accommodate the limiting plate 303, achieving initial positioning and connection between the mounting bracket 2 and the fixing plate 301. The insertion block 310 is shaped to match the insertion hole 304 and is used to insert into the insertion hole 304 to fix the mounting bracket 2.

[0037] When installing this clamping fixture, first align the limiting plate 303 at the bottom of the connecting plate 302 and insert it into the mounting groove 309 on the fixing plate 301. Next, rotate the drive screw 308 to rotate the second movable rod 307. As the second movable rod 307 rotates, its end slope contacts the end slopes of the two first movable rods 306. This causes the two first movable rods 306 to slide outward along the inner wall of the limiting groove 305, thereby accurately inserting the plug 310 fixed at its end into the insertion hole 304 on the limiting plate 303, achieving a stable installation of the mounting bracket 2. When disassembling the fixture, simply rotate the drive screw 308 in the opposite direction. Under the spring force, the second movable rod 307 returns to its original position, causing the two first movable rods 306 to slide inward, and the plug 310 is then pulled out of the insertion hole 304, completing the disassembly. This design makes the installation and disassembly of the fixture extremely convenient, significantly improving work efficiency and reducing downtime caused by changing fixtures.

[0038] The fixed plate 301 has a limiting groove 305 inside. The two movable rods 306 are slidably installed inside the limiting groove 305. The two movable rods 306 are elastically connected by a spring. The near ends of the two movable rods 306 are provided with a conical surface. The end of the movable rod 307 away from the drive screw 308 is also provided with a conical surface.

[0039] Specifically, the limiting groove 305 inside the fixed plate 301 provides a sliding track for the first movable rod 306, ensuring its linear movement. The two movable rods 306 slide within the limiting groove 305 and are connected by a spring, which allows the first movable rod 306 to return to its original position after the external force is removed. Through the conical surface design of the first movable rod 306, when the second movable rod 307 rotates, its conical surface can smoothly push against the conical surface of the first movable rod 306, causing the first movable rods 306 to move away from or closer to each other, thus realizing the insertion and removal of the insert block 310.

[0040] The two fixed plates 301 correspond one-to-one with the connecting plates 302 at their respective positions, and the drive screw 308 passes through the outside of the fixed plate 301 and extends to its exterior.

[0041] Specifically, the rotating drive screw 308 drives the internal movable rod 307 to rotate, thereby realizing the movement of the movable rod 306 and the insert block 310, and completing the quick installation and disassembly of the mounting bracket 2.

[0042] Multiple rotating shafts 10 are rotatably connected to the outer side of the support frame 6. The rotating shafts 10 are used to support the side of the linear module base. The outer sides of the two cranks 11 are respectively fixedly connected to one end of the rotating rod 4 at the corresponding position. Rubber pads are provided on the outer sides of the first support plate 8 and the second support plate 13.

[0043] Specifically, the main function of the rotating shaft 10 is to support the side of the linear module base, providing additional stability and support to ensure the stability of the linear module base during clamping and processing. The rubber pad is mainly used to increase the friction between the rubber pad and the linear module base, preventing the base from sliding during clamping and processing. At the same time, the rubber pad also has a certain shock absorption and buffering effect, which can protect the surface of the base and avoid damage caused by hard contact.

[0044] In summary, this fixture can secure the four sides of the linear module base, significantly improving clamping efficiency, greatly reducing clamping time, ensuring machining accuracy, and meeting high-precision requirements. The four-sided fixing design enhances stability, preventing the base from shifting or deforming during milling, ensuring smooth machining, and improving machining quality. Furthermore, this fixture is highly versatile, can be quickly adjusted, and adapts to linear module bases of various specifications and sizes.

[0045] Working principle: The specific operating principle of this device is as follows:

[0046] Insert the limiting plate 303 at the bottom of the connecting plate 302 into the mounting groove 309 inside the fixing plate 301. At this time, by rotating the drive screw 308, the second movable rod 307 will rotate. The inclined surface at the end of the second movable rod 307 will contact the inclined surface at the end of the two first movable rods 306. At this time, the two first movable rods 306 will move away from each other along the inner wall of the limiting groove 305, and then insert the insert block 310 into the interior of the insertion hole 304 to complete the installation of the mounting bracket 2 and realize the quick installation of this clamping fixture. At the same time, by rotating the drive screw 308 in the opposite direction, the second movable rod 307 will be reset. At this time, the two first movable rods 306 will be reset under the action of the spring, allowing the insert block 310 to disengage from the interior of the insertion hole 304, thus completing the quick disassembly of this clamping fixture.

[0047] The linear module base is placed inside the mounting bracket 2. By activating the electric telescopic rod 9, the output end of the electric telescopic rod 9 moves, causing the movable plate 14 to move synchronously. This, in turn, causes the end of the crank 11 to swing. Under the traction force of the crank 11, the rotating rod 4 rotates, which in turn causes the connecting arm 5 to rotate. Together with the connecting shaft 7, the support plate 8 is attached to the upper and lower sides of the linear module base. At the same time, by activating the electric telescopic rod 15, the support plate 13 is moved, allowing the support plate 13 to be attached to the left side of the linear module base. By rotating the rotating shaft 10, the rotating shaft 10 is attached to the right side of the linear module base. In this way, the four sides of the linear module base are fixed, which greatly improves the clamping efficiency, significantly shortens the clamping time, and ensures the processing accuracy, meeting the requirements of high-precision processing.
