Description

Technical Field

[0001] This utility model belongs to the field of fixed clamping technology, specifically relating to a fixed clamping fixture for machining that prevents flying chips. Background Technology

[0002] A machining fixture is a device used to precisely position and firmly clamp a workpiece on a machine tool. Its core function is to ensure that the workpiece remains stable during the machining process and to prevent displacement caused by external forces or vibrations, thereby ensuring machining accuracy and quality. In use, the fixture is fixed to a designated position such as the machine tool worktable by bolts or other connecting parts, and then the workpiece is clamped by manual, pneumatic, or hydraulic means.

[0003] Fixtures are key equipment for ensuring machining accuracy and efficiency. Traditional machining fixtures often lack effective measures to prevent flying chips during use. The flying chips generated during machining not only pollute the working environment but may also cause injury to operators and affect the normal operation of machining equipment. Therefore, a machining fixture with anti-flying chips is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a fixed fixture for machining that provides an automatic opening and closing splash guard to prevent flying debris, in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A fixed fixture for machining to prevent flying chips includes a base and a working platform disposed on the base, wherein a clamping mechanism is provided on the working platform;

[0007] It also includes:

[0008] The splash guards are two in number and symmetrically rotated on the working circular platform, and the two splash guards form a semi-circular structure.

[0009] A push-pull plate is telescopically mounted on the base and is connected to a splash guard.

[0010] As a further optimization of this utility model, extension plates are provided on both sides of the splash guard, and protruding rods are provided on the extension plates, with the protruding rods located obliquely below the rotation axis of the splash guard.

[0011] As a further optimization of this utility model, the push-pull plate is symmetrically provided with inclined grooves, the protruding rod is slidably disposed in the inclined grooves, the base is provided with a push-pull cylinder, and the output end of the push-pull cylinder is fixedly connected to the push-pull plate.

[0012] As a further optimization of this utility model, the clamping mechanism includes a clamping cylinder, which is disposed below the working round table. The output end of the clamping cylinder is slidably disposed on the working round table, and a clamping plate is fixedly disposed on the output end of the clamping cylinder. A placement seat is disposed on the working round table.

[0013] As a further optimization of this utility model, the splash guard is provided with a processing port, and when the splash guard is closed, the processing port forms a circular hole.

[0014] As a further optimization of this utility model, the splash shield is provided with a cooling pipe opening, and when the splash shield is closed, the splash shield forms a circular hole.

[0015] As a further optimization of this utility model, the edge of the working platform is rounded.

[0016] The beneficial effects of this utility model are as follows:

[0017] Unlike existing technologies, in practical use, two symmetrically rotating splash guards mounted on the worktable can easily and quickly form a semi-circular structure by pushing and pulling plates with a push-pull cylinder and through the sliding cooperation of the inclined groove and the convex rod. This effectively blocks flying chips generated during processing, protecting the operator's safety and maintaining a clean working environment. The machining port and cooling pipe port on the splash guard form circular holes after the splash guard is closed, facilitating the operation of machining tools and the injection of coolant, ensuring smooth processing.

[0025] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] Example 1

[0027] like Figure 1 - Figure 6 As shown, a fixed fixture for machining with anti-flying chips includes a base 1 and a working platform 2 mounted on the base 1. The working platform 2 has rounded edges and a clamping mechanism 3. It also includes two splash guards 4 symmetrically and rotatably mounted on the working platform 2, forming a semi-circular structure. A push-pull plate 5 is telescopically mounted on the base 1 and connected to the splash guards 4. The working platform 2 serves as the base platform for supporting the workpiece. Its rounded edges effectively prevent interference with the splash guards 4 during opening and closing, ensuring smooth rotation of the splash guards 4. It also reduces collision wear that may be caused by right-angled edges, extending the service life of the fixture. The clamping mechanism 3 provides a guarantee for the stable fixation of the workpiece. The cooperative design of the splash guards 4 and the push-pull plate 5 is the key to achieving the chip protection function and lays the foundation for subsequent safe machining.

[0028] The splash guard 4 has extension plates 41 on both sides, and protruding rods 42 on the extension plates 41. The protruding rods 42 are located diagonally below the rotating shaft of the splash guard 4. Cooling pipe ports 7 are opened on the splash guard 4. When the splash guard 4 is closed, it forms a circular hole. A machining port 6 is also opened on the splash guard 4. When the splash guard 4 is closed, the machining port 6 forms a circular hole. The extension plates 41 and protruding rods 42 cleverly convert the linear motion of the push-pull plate 5 into the rotation of the splash guard 4. This structural design not only simplifies the transmission process but also improves the stability and reliability of the motion. The presence of cooling pipe ports 7 and machining ports 6 ensures that while the splash guard 4 is closed to form a protective structure, it does not affect the injection of coolant or the operation of machining tools. This ensures machining efficiency and effectively blocks flying chips, making the machining process safer and more efficient.

[0029] The push-pull plate 5 has symmetrically opened inclined grooves 51, and the protruding rod 42 is slidably disposed in the inclined grooves 51. The base 1 is provided with a push-pull cylinder 52, and the output end of the push-pull cylinder 52 is fixedly connected to the push-pull plate 5. The inclined groove 51 on the push-pull plate 5 and the protruding rod 42 slide together to form a stable transmission structure, which can accurately control the opening and closing angle of the splash guard 4. The push-pull cylinder 52 serves as a power source, providing stable and strong power for the extension and retraction of the push-pull plate 5, ensuring that the splash guard 4 closes quickly and accurately before processing and opens in time after processing, which greatly improves the automation level and work efficiency of the fixture.

[0030] The clamping mechanism 3 includes a clamping cylinder 33, which is located below the working platform 2. The output end of the clamping cylinder 33 is slidably mounted on the working platform 2. A clamping plate 31 is fixedly mounted on the output end of the clamping cylinder 33. A placement seat 32 is provided on the working platform 2. The clamping cylinder 33 drives the clamping plate 31 to rise and fall through the output end, realizing fast and precise clamping operation. The placement seat 32 provides a stable placement position for the workpiece and cooperates with the clamping plate 31 to fix the workpiece, effectively preventing the workpiece from shifting during processing and ensuring processing accuracy and product quality.

[0031] It should be noted that the working principle of this anti-chip machining fixture is as follows: First, the workpiece is placed on the placement seat 32 of the worktable 2. The clamping cylinder 33 is activated, and its output end drives the clamping plate 31 to descend from below the worktable 2 and clamp the workpiece. Then, the push-pull cylinder 52 is activated, pushing the push-pull plate 5 to move telescopically on the base 1. Since the inclined groove 51 on the push-pull plate 5 is in sliding engagement with the protruding rod 42 on the extension plate 41 of the splash guard 4, and the protruding rod 42 is located obliquely below the rotation axis of the splash guard 4, the movement of the push-pull plate 5 will drive the two symmetrically arranged splash guards 4 to rotate around the worktable. The rotating shaft on the 2 rotates until the two splash guards 4 close to form a semi-circular structure. At this time, the machining port 6 and the cooling pipe port 7 on the splash guard 4 form circular holes. The machining tool can operate on the workpiece through the machining port 6, and the cooling pipe can inject coolant through the cooling pipe port 7. During the machining process, the splash guard 4 can effectively block flying debris. The rounded corners of the edge of the working platform 2 will not hinder the movement trajectory of the splash guard 4. After the machining is completed, the push-pull cylinder 52 moves in the opposite direction, pulling the push-pull plate 5 to open the splash guard 4. Then the clamping cylinder 33 releases the clamping plate 31, and the workpiece can be taken out.

[0032] In another embodiment, since the splash guard is prone to internal damage during long-term installation, it needs to be disassembled and cleaned. A fixed block 8 is fixedly connected to the push-pull cylinder. The push-pull plate 5 is provided with an insertion hole 9. The fixed block 8 is provided with a mounting hole 10. Two insertion blocks 11 are elastically disposed within the mounting hole 10. The two insertion blocks 11 are elastically connected by a spring 12. Both insertion blocks 11 are inserted into the insertion hole 9. A snap-fit ​​block 13 is fixedly connected to the side of each insertion block 11 that is far apart from each other. A snap-fit ​​hole 14 is provided on the corresponding side wall of the insertion hole 9, and the snap-fit ​​block 13 is inserted into the snap-fit ​​hole 14. Inside, after the two plug-in blocks 11 are inserted into the plug-in hole 9, the snap-fit ​​block 13 abuts against the side wall of the plug-in hole 9. The two plug-in blocks 11 approach each other and the spring 12 is squeezed and deformed. When the snap-fit ​​block 13 moves to the position of the snap-fit ​​hole 14, under the elastic force of the spring 12, the snap-fit ​​block 13 is inserted into the snap-fit ​​hole 14. Both sides of the mounting hole 10 are provided with driving holes. The end of the plug-in block 11 away from the snap-fit ​​block 13 is fixedly connected to a handle 15. When the two handles 15 are squeezed, the snap-fit ​​block 13 separates from the snap-fit ​​hole 14, and the plug-in block 11 can be separated from the plug-in hole 9, so as to achieve the disassembly effect of the fixing block 8 and the push-pull plate 5.

[0033] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
