Abstract
Description
Technical Field
[0001] This utility model relates to a clamping device for tungsten carbide cutting tools, belonging to the field of tungsten carbide cutting tool processing technology. Background Technology
[0002] Tungsten carbide cutting tools are tools used in mechanical manufacturing to cut and machine mechanical workpieces. When machining tungsten carbide cutting tools, they typically need to be clamped and fixed, thus requiring clamping devices to secure them.
[0003] While existing clamping devices can perform basic clamping tasks when holding tungsten carbide cutting tools, in practice, operators need to manually adjust the position of the cutting tool to align it with the workpiece. This process is not only time-consuming and labor-intensive, but also prone to deviations due to the limitations of manual operation. Even experienced operators cannot guarantee millimeter-level or higher alignment accuracy every time. Such alignment deviations lead to uneven contact between the tool and the workpiece during machining, resulting in inaccurate machining dimensions, substandard surface roughness, and other problems, severely affecting the quality of the workpiece and rendering the clamping device ineffective.
[0004] In addition, a large amount of debris and impurities are inevitably generated during the machining of tungsten carbide tools. After the machining is completed, the workers need to manually clean them, which brings inconvenience to the workers and makes the clamping device less convenient to use. Utility Model Content

The connecting structure can slide in the opposite direction along the length of the frame and slide in the opposite direction along the width of the frame to centrally clamp the placed tungsten carbide tool.
[0009] Preferably, the connecting structure includes two sliders, each with a drive rod fixed at both ends. One of the drive plates is slidably connected to the outer surface of the two drive rods. Inclined grooves are provided on both sides of the two drive plates, and a push frame is fixed to the middle of the adjacent sides of the two drive plates.
[0010] Preferably, the two sliders are threaded at the middle of the same end to the outer surfaces of both sides of the bidirectional threaded rod, the outer surfaces of the two sliders are slidably connected to the inner walls of the two grooves, and the outer surface of the bidirectional threaded rod is rotatably connected to one end of the frame.
[0011] Preferably, one end of each driving rod is fixed to one end of each slider, the outer surface of each driving rod is slidably connected to the inner wall of each inclined groove, and each pair of adjacent inclined grooves are symmetrically inclined and pass through both sides of each driving plate.
[0012] Preferably, the two drive plates are symmetrically arranged, each drive plate has a V-shaped cross section, the two push frames are fixed at opposite ends at the middle of the adjacent sides of the two drive plates, the two push frames have an L-shaped vertical cross section, and the outer surfaces of the two push frames are slidably connected to the upper surface of the frame.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0024] Example 1
[0025] This utility model provides a tungsten carbide cutting tool clamping device.
[0026] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The device includes a frame 1, which is the main body of the clamping device. Slide grooves 2 are provided on both sides of the frame 1, which limit the sliding of two sliders 5. Connecting ears 15 are fixed at two opposite corners of the frame 1. These connecting ears 15 are bolted to the machining table using pre-drilled holes 16. Each connecting ear 15 has a pre-drilled hole 16 in the middle. A drive motor 3 is fixed at one corner of the frame 1. A bidirectional threaded rod 4 is fixed to the drive end of the drive motor 3. Connecting structures are provided on the outer surfaces of both sides of the bidirectional threaded rod 4. These connecting structures include two sliders 5, with driving rods 6 fixed at both ends of each slider 5. One of the driving plates 7 is slidably connected to the outer surface of the two driving rods 6. Inclined grooves 8 are provided on both sides of the two driving plates 7. A pusher frame 9 is fixed to the middle of the adjacent sides of the two driving plates 7. The driving plates 7 can be directly removed from the driving rods 6 to replace driving plates 7 with those suitable for different sizes of tungsten carbide tools, thus improving the adaptability of the clamping device.
[0027] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4It is worth noting that the two sliders 5 are threadedly connected at the middle of the same end to the outer surfaces of both sides of the bidirectional threaded rod 4. The outer surfaces of both ends of the two sliders 5 are slidably connected to the inner walls of the two slide grooves 2. The outer surface of the bidirectional threaded rod 4 is rotatably connected to one end of the frame 1. One end of each driving rod 6 is fixed to one end of each slider 5. The outer surface of each driving rod 6 is slidably connected to the inner wall of each inclined groove 8. Each pair of adjacent inclined grooves 8 are symmetrically inclined and pass through both sides of each driving plate 7. The two driving plates 7 are symmetrically arranged. The cross section of each driving plate 7 is V-shaped. The two push frames 9 are fixed at opposite ends to the middle of the adjacent sides of the two driving plates 7. The vertical sections of the two push frames 9 are L-shaped. The outer surfaces of the two push frames 9 are slidably connected to the upper surface of the frame 1.
[0028] In use, this invention works as follows: A drive motor 3 drives a bidirectional threaded rod 4 to rotate, causing two sliders 5, threaded to the outer surfaces of both sides of the bidirectional threaded rod 4, to slide in opposite directions under the limiting action of the sliding groove 2. The two sliders 5 sliding in opposite directions drive the drive rods 6 fixed at both ends to move. The moving drive rods 6, in conjunction with the inclined groove 8, drive two drive plates 7 to move in opposite directions. The two drive plates 7 moving in opposite directions drive two push frames 9 fixed at the center of their adjacent sides to move in opposite directions. When the two sliders 5 approach each other, the two push frames 9 simultaneously move closer together, pushing the placed tungsten carbide tool to the central area, achieving a centered clamping effect. Alignment is automatically completed during clamping, eliminating the need for manual alignment and avoiding incomplete alignment by manual methods, thus improving the clamping device's effectiveness. When dealing with tungsten carbide tools of different sizes, the drive plates 7 can be directly removed and replaced with drive plates of the appropriate size.
[0029] Example 2
[0030] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 An automatic cleaning and collection function has been added based on Embodiment 1;
[0031] Please refer to it again. Figure 1 , Figure 2 , Figure 3 and Figure 4 It is worth noting that two push frames 9 are fixed with fixed frames 10 at their close ends, and brush holders 11 are fixed on both sides of the two fixed frames 10. A storage groove 12 is provided in the middle of the frame body 1. Several through grooves 13 are provided at the upper end of the storage groove 12, and a collection hopper 14 is provided on the inner wall of the storage groove 12. The middle of each fixed frame 10 is fixed to one end of each push frame 9. The upper ends of each pair of adjacent brush holders 11 are fixed to both sides of one of the fixed frames 10, and the bristles of the two brush holders 11 are attached to the upper surface of the frame body 1.
[0032] In use, this invention works as follows: a drive motor 3 drives a bidirectional threaded rod 4 to rotate, causing two sliders 5, threaded to the outer surfaces of both sides of the bidirectional threaded rod 4, to move accordingly. The sliders 5, via a drive rod 6 and a drive plate 7, drive a pusher frame 9 to move. The pusher frame 9 then drives a fixed frame 10, fixed at one end, to move. The fixed frame 10, in turn, drives two brush holders 11, fixed on both sides, to move. The moving brush holders 11 clean the debris generated during the machining of tungsten carbide tools. The cleaned debris is disturbed and falls from the through slot 13 into a collection hopper 14. Workers only need to periodically empty the debris collected in the collection hopper 14, achieving automatic cleaning and collection without manual intervention, thus improving the ease of use of the clamping device.
