Description

TECHNICAL FIELD

[0001] The present application relates to the field of machining, in particular to a cutting clamp. BACKGROUND

[0002] As a common industrial equipment, cutting machines have been widely applied in the field of precision machining. With the development of manufacturing industry and the progress of technology, cutting machines have been developed from the initial single function to the current multi-function, high precision and high efficiency, which greatly improves the production efficiency and product quality. Especially in the industries of optical fiber communication and precision electronic component manufacturing, there are very high requirements for cutting precision and stability. However, the existing cutting clamp has certain limitations and cannot fully meet the needs of these high-end applications.

[0003] In the prior art, in order to solve the stability and positioning problem of workpiece in the cutting process, the following methods are usually adopted: one is to use the traditional bolt fastening method, which fixes the workpiece by manually tightening the bolt. Although this method is simple to operate, it is low in efficiency when frequently changing the workpiece; two is to use a pneumatic clamping device, which clamps the workpiece by driving the clamping jaw with compressed air. This method can realize fast clamping, but it needs an additional air supply system, which increases the complexity of the equipment; three is to use a hydraulic clamping device, which clamps the workpiece by driving the clamp with a hydraulic cylinder. This method can provide a larger clamping force, but it also needs a complex hydraulic system, which has a high maintenance cost; four is to use a spring clamping device, which clamps the workpiece by pre-tightening the spring. Although this method has a simple structure, the spring is prone to fatigue failure after a long time of use, resulting in a decrease in clamping force.

[0004] Although the above-mentioned methods can meet the clamping requirements of cutting machines to some extent, there are still some deficiencies. For example, the traditional bolt fastening method and the spring clamping device are low in efficiency when frequently changing the workpiece, while the pneumatic and hydraulic clamping devices need additional auxiliary systems, which increases the complexity and maintenance cost of the equipment. In addition, the existing clamps still have certain challenges when clamping the workpiece in multiple directions, especially in three-dimensional space, which cannot completely guarantee the stability of the workpiece in the cutting process, thereby affecting the cutting quality and production efficiency. Therefore, it is urgent to provide a cutting clamp which is convenient to clamp and stable in cutting to solve these problems. CONTENT OF THE INVENTION

[0005] The purpose of the present application is to provide a cutting clamp.

[0006] The above-mentioned technical purpose of the present application is achieved through the following technical solutions: a cutting fixture, comprising a fixture body arranged on a cutting base plate, a positioning groove provided on the fixture body, an installation and fixing block provided on the fixture body, a first elastic member provided on the installation and fixing block, a push block connected to the end of the first elastic member away from the installation and fixing block, the push block and the installation and fixing block cooperate to clamp or release the first elastic member, and are used to adjust the distance between the push block and the positioning groove, and a cover plate is provided on the fixture body to cooperate with the fixture body to clamp the workpiece.

[0007] By adopting the above technical solution, a positioning groove is set on the fixture body to facilitate the placement and positioning of the workpiece. The first elastic member on the fixed block is installed to cooperate with the push block. The distance from the push block to the positioning groove can be adjusted to adapt to workpieces of different sizes. The operation is convenient and effective clamping or release can be achieved. At the same time, the cover plate on the fixture body and the fixture body work together to clamp the workpiece, further enhancing the fixing effect of the workpiece. The overall structure makes the cutting fixture more convenient and flexible when clamping the workpiece, which can effectively improve the clamping efficiency and better ensure the stability of the workpiece during the cutting process, thereby helping to improve cutting quality and production efficiency.

[0008] Optionally, a sliding groove is provided inwardly on the push block, and a sliding rail is provided on the clamp body, and the push block is mounted on the sliding rail by being engaged with the sliding groove.

[0009] By adopting the above technical solution, the concave groove on the push block cooperates with the slide rail on the fixture body, providing the push block with a clear guide during movement, ensuring that the push block can only move smoothly and linearly along the direction of the slide rail, avoiding the push block from offsetting or shaking when adjusting its position. This allows for more precise control of the distance between the push block and the positioning groove, improving the accuracy and stability of workpiece clamping, further enhancing the clamping accuracy of the cutting fixture, and facilitating the positional accuracy of the workpiece during the cutting process, thereby improving cutting quality. Furthermore, the movement of the push block is smoother, making it easier to operate and improving work efficiency.

[0010] Optionally, a limit block is provided on the clamp body, and the limit block is provided at an end of the positioning slot away from the push block.

[0011] By adopting the above technical solution, when clamping a workpiece, the limit block can accurately limit the workpiece's position, preventing the workpiece from being inaccurately positioned during insertion into the positioning slot, ensuring that the workpiece is accurately placed in the predetermined position every time, and improving the consistency and accuracy of workpiece positioning. During the cutting process, the limit block can effectively prevent the workpiece from being displaced by external forces such as cutting force, and cooperate with the push block to further enhance the workpiece's fixation in this direction, thereby better ensuring the stability of the workpiece during cutting, helping to improve cutting accuracy, reduce defective products caused by workpiece displacement, and enhance product quality and production efficiency.

[0012] Optionally, the cover plate is rotatably disposed on the clamp body, and a pressure column is provided on the cover plate.

[0013] By adopting the above technical solution, the cover is rotatably arranged on the fixture body, making the opening and closing operation of the cover extremely convenient, and convenient for quickly opening and closing the cover when clamping the workpiece. When the cover is closed, the pressure column can exert a certain pressure on the workpiece in the Z direction, and work together with the clamping force of the push block and the limit block in the XY direction to achieve effective clamping of the workpiece in three-dimensional space. During the cutting process, the pressure column ensures that the workpiece remains stable in the Z direction, preventing the workpiece from upward displacement or jumping due to factors such as laser burning and cutting force, effectively avoiding the cutting size deviation caused by loose workpiece, greatly improving the stability and accuracy of cutting, and thus improving product quality. At the same time, the design of the rotating cover and pressure column also improves the operational convenience and work efficiency of the entire cutting fixture.

[0014] Optionally, the clamp body is provided with a snap-on bottom block, the cover plate is provided with a hook, and the hook and the snap-on bottom block are engaged with each other.

[0015] By adopting the above technical solution, when installing the cover, the hook and the snap bottom block are easily and conveniently connected, which can quickly achieve a tight connection between the cover and the fixture body, thereby improving the assembly efficiency of the fixture. After being connected, this connection method can provide reliable fastening force, effectively preventing the cover from accidentally opening during the cutting process, and ensuring the stability of the overall structure of the fixture. The stable cover can better cooperate with the fixture body to clamp the workpiece, ensuring that the workpiece will not be displaced or shaken due to a loose cover during cutting, further enhancing the stability of the workpiece during the cutting process, thereby helping to improve cutting accuracy, reduce defective products caused by unstable workpieces, and improve product quality, while also ensuring the safety and reliability of the cutting operation.

[0016] Optionally, the hook is rotatably arranged on the cover plate, and a second elastic member is provided on the hook. The cover plate cooperates with the hook to clamp or release the second elastic member to adjust the relative rotation angle between the hook and the cover plate.

[0017] By adopting the above-mentioned technical solution, the relative rotation angle between the hook and the cover plate is adjusted by clamping or releasing the second elastic member through the cooperation between the cover plate and the hook, making the clamping process between the hook and the buckle bottom block more flexible and having a certain degree of adaptability. When installing the cover plate, the position of the hook can be more easily adjusted according to the actual situation to ensure that it is accurately clamped into the buckle bottom block, improving the convenience and success rate of the clamping. At the same time, the second elastic member can provide a certain amount of pre-tightening force after clamping, making the connection between the hook and the buckle bottom block more stable, effectively preventing the hook from accidentally detaching due to factors such as vibration, and further enhancing the reliability of the connection between the cover plate and the fixture body. This helps to maintain the stability of the fixture structure at all times during the cutting process, ensuring stable clamping of the workpiece, thereby improving cutting accuracy and product quality, reducing waste caused by loose fixtures, and improving production efficiency.

[0018] Optionally, an optical cable fixing block is provided on the clamp body.

[0019] By adopting this technical solution, the cable fixing block effectively secures the optical cable during fiber-optic cutting operations, preventing it from shaking, shifting, or becoming tangled during the cutting process. The stable cable position helps ensure the accuracy of the cutting operation, preventing changes in the cable's position from affecting the laser transmission path or interfering with the cutting process, thereby improving cutting quality. Furthermore, properly securing the optical cable reduces potential safety hazards caused by cable movement, ensuring operator safety and facilitating cable management and maintenance. This makes the entire cutting operation more organized and efficient, helping to improve overall production efficiency.

[0020] Optionally, a plurality of mounting holes are provided on the clamp body.

[0021] By adopting the above technical solution, the mounting hole can be used for the installation of the magnet. With the help of the adsorption force between the magnet and the cutting base, the fixture body can be quickly installed on the cutting base, which shortens the installation time and significantly improves the installation efficiency. The advantages are particularly prominent in production scenarios where frequent fixture replacement or adjustment of the fixture position is required. The magnet adsorption installation method ensures the firmness and stability of the fixture body on the cutting base, effectively avoiding the workpiece positioning deviation and reduced cutting accuracy caused by the loosening of the fixture during the cutting process, thereby ensuring high-quality cutting results. The magnet adsorption installation method does not require additional complex connection structures or tools, simplifies the installation operation process, reduces the difficulty of the operator's work, and at the same time reduces the risk of damage to the fixture and cutting equipment due to improper installation, thereby improving the overall reliability and service life of the equipment.

[0022] In summary, this application has at least the following beneficial effects:

[0023] 1. Easy clamping. Through the cooperation of the push block and the first elastic member, the distance between the push block and the positioning groove can be quickly adjusted, which facilitates the rapid clamping and disassembly of the workpiece and improves work efficiency.

[0024] 2. Stable cutting: through the multiple clamping effects of the push block in the XY direction and the pressure column in the Z direction, the stability of the workpiece during the cutting process is ensured, the cutting size deviation caused by external forces is avoided, and the cutting quality is improved;

[0025] 3. The structure is simple and universal, the overall structure is compact, and no additional auxiliary system is required, which reduces the complexity and maintenance cost of the equipment. At the same time, it is suitable for various types of workpieces and has a wide range of applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The present application is further described in detail below with reference to the accompanying drawings.

[0033] Example 1

[0034] In this embodiment, referring to Figure 1-4A cutting fixture includes a cutting base plate 1, a fixture body 2, a positioning groove 3, a mounting block 4, a first elastic member 5, a push block 6, a cover plate 7, a slide groove 8, a slide rail 9, a limit block 10, a pressure column 11, a snap-on bottom block 12, a hook 13, a second elastic member 14, an optical cable fixing block 15, and a mounting hole 16. The fixture body 2 is provided with a positioning groove 3 for placing a workpiece to be cut; the mounting block 4 is provided with a first elastic member 5, and the end of the first elastic member 5 away from the mounting block 4 is connected to a push block 6. The push block 6 and the mounting block 4 cooperate to clamp or release the first elastic member 5, and are used to adjust the distance between the push block 6 and the positioning groove 3; the fixture body 2 is provided with a cover plate 7, which cooperates with the fixture body 2 to clamp the workpiece, achieving the effect of convenient clamping and stable cutting.

[0035] Specifically, the fixture body 2, serving as the foundation of the entire fixture, is made of a high-strength aluminum alloy with excellent rigidity and corrosion resistance. A snap-on bottom block 12 is fixed to the fixture body 2 and is used to cooperate with a hook 13 on the cover plate 7 to lock the cover plate 7. The hook 13 is rotatably mounted on the cover plate 7 via a pin. A second elastic member 14 is provided on the hook 13. The second elastic member 14 can be a spring or a rubber pad, and is used to adjust the relative rotation angle between the hook 13 and the cover plate 7, allowing the hook 13 to be securely engaged with the snap-on bottom block 12 or to be unlocked and disengaged from the snap-on bottom block 12 via the second elastic member 14.

[0036] Reference Figure 2 , a slide groove 8 is provided inwardly on the push block 6, and a slide rail 9 is provided on the fixture body 2. The push block 6 is mounted on the slide rail 9 through the slide groove 8 and can slide freely on the slide rail 9. The push block 6 is made of wear-resistant steel material, and the surface is hardened to improve the service life. The slide rail 9 is made of stainless steel material and has good corrosion resistance. The slide groove 8 and the slide rail 9 have a close matching relationship, which ensures the smooth movement of the push block 6. The first elastic member 5 can be a spring or a spring, one end of which is fixed on the mounting block 4, and the other end is connected to the push block 6. Through the elastic action of the first elastic member 5, the push block 6 can adapt to the processing of workpieces of different specifications, stably clamp the workpiece to be cut, and facilitate the cutting of the workpiece.

[0037] Reference Figure 3 The clamp body 2 is also provided with a limit baffle 10, which is located at the end of the positioning groove 3 away from the push block 6 and is used to prevent the workpiece from excessively moving in the X direction. The limit baffle 10 has good wear resistance and self-lubricating properties, reducing friction with the workpiece. The cover plate 7 is rotatably set on the clamp body 2, which can be achieved by a pin or other rotating mechanism. A pressure column 11 is provided on the cover plate 7, and the pressure column 11 can be a metal rod or a plastic rod, which is used to press the workpiece in the Z direction. A rubber pad can be added to the lower end of the pressure column 11 to increase the contact area with the workpiece, improve the clamping effect, and prevent damage to the workpiece.

[0038] Reference Figure 4 The fixture body 2 also features a cable retaining block 15, which secures the optical cable and prevents interference during cutting. Made of polycarbonate, this block offers excellent insulation and high-temperature resistance. Several mounting holes 16 are provided on the fixture body 2 for mounting magnets, which attach to the metal cutting base plate 1 to enhance the fixture's stability.

[0039] The implementation principle of this embodiment is as follows: the cutting base plate 1 and the fixture body 2 are debugged and installed according to the cutting requirements. After debugging and installation, the operator installs the workpiece insert into the positioning groove 3 and cooperates with the limit block 10 to initially stabilize the workpiece setting and installation; the push block 6 clamps the insert in the X direction under the action of the first elastic member 5, covers the cover plate 7, and the hook 13 is hooked with the buckle bottom block 12, and the pressure column 11 clamps the workpiece insert in the Z direction. Since the workpiece insert is clamped in the X, Y, and Z directions, the force of laser burning and cutting will not affect the size of the insert cut during the cutting process, thereby achieving stable cutting of the insert. This embodiment solves the problems of inconvenient fixture clamping and unstable cutting in the prior art, and improves cutting quality and production efficiency.

[0040] Example 2

[0041] This embodiment differs from the previous embodiment in that the push block 6 is replaced with an electric push rod, replacing the first elastic member 5 and the manual push block 6. The electric push rod is mounted on the fixture body 2 and its extension and retraction are controlled by a controller to achieve precise movement of the push block 6. The stroke of the electric push rod can be adjusted according to actual needs, improving the adaptability and flexibility of the fixture. The electric push rod's housing is waterproof and dustproof, making it suitable for harsh working environments.

[0042] The operating principle of this embodiment is as follows: the cutting base plate 1 and the fixture body 2 are debugged and installed according to the cutting requirements. After debugging and installation, the employee inserts the ferrule into the positioning slot 3. The controller controls the electric push rod to extend and retract, pushing the push block 6 to clamp the ferrule in the X and Y directions. The cover plate 7 is then installed, the hook 13 is hooked with the snap bottom block 12, and the pressure column 11 clamps the ferrule in the Z direction. Because the ferrule is clamped in all directions, the force of the laser cutting does not affect the cut size of the ferrule during the cutting process, thus achieving stable cutting of the ferrule. By introducing the electric push rod, this embodiment further improves the automation level and operational convenience of the fixture, making it particularly suitable for large-scale production and automated production lines.

[0043] Example 3

[0044] The difference between this embodiment and the above embodiment is that a pneumatic clamping device is used to replace the cover plate 7. The pneumatic clamping device includes a cylinder, a piston rod and a pressure plate. The cylinder is installed on the fixture body 2, and the piston rod is connected to the pressure plate. The air supply control system controls the air intake and exhaust of the cylinder to achieve the up and down movement of the pressure plate. The pressure plate is made of soft materials, such as silicone or rubber, to increase the contact area with the workpiece and improve the clamping effect. The pneumatic clamping device has a fast response speed and is easy to operate, and is suitable for high-frequency workpiece replacement scenarios.

[0045] The implementation principle of this embodiment is as follows: by debugging and installing the cutting base plate 1 and the fixture body 2 according to the cutting requirements, after debugging and installation, the employee installs the ferrule into the positioning groove 3, and the push block 6 clamps the ferrule in the XY direction under the action of the first elastic member 5. The pneumatic clamping device is started, and the cylinder drives the pressure plate downward to clamp the ferrule in the Z direction. Since the ferrule is clamped in the XYZ directions, the force of the laser burning and cutting will not affect the size of the ferrule cutting during the cutting process, thereby achieving stable cutting of the ferrule. By introducing the pneumatic clamping device, this embodiment further improves the clamping force and response speed of the fixture, which is particularly suitable for high-precision and high-speed cutting applications.

[0046] The embodiments of this specific implementation method are all preferred embodiments of the present application and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
