Detailed Implementation
[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.
[0021] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, this utility model provides a technical solution: an adjustable fixture for machining angle blocks, including an operating table 1, a support frame 2 fixedly connected to the top of the operating table 1, a machining device 3 installed inside the support frame 2, a movable groove 4 opened at the top of the operating table 1, a movable rod 5 slidably connected inside the movable groove 4, an adjusting plate 6 fixedly connected to one side of the movable rod 5, a first adjusting component 7 installed on one side of the adjusting plate 6, a stretching groove 8 opened inside the first adjusting component 7, a second adjusting component 9 slidably connected inside the stretching groove 8, first moving grooves 10 opened at both ends of the first adjusting component 7, second moving grooves 11 opened at both ends of the first adjusting component 7, a limiting rod 12 slidably connected inside the first moving groove 10, and the other end of the limiting rod 12 slidably connected inside the second moving groove 11. Next, both ends of the second adjusting component 9 are provided with several limiting grooves 13. The surface of one end of the limiting rod 12 is slidably connected to the inside of the limiting groove 13. By moving the limiting rod 12, the limiting rod 12 is moved out of the inside of the limiting groove 13, thereby releasing the limiting of the second adjusting component 9. At this time, the length of the second adjusting component 9 moving out can be adjusted according to the size of the angle block. After the adjustment is completed, the limiting rod 12 is moved back into the inside of the limiting groove 13 so that the second adjusting component 9 can complete the limiting again. This setting allows the operator to quickly adjust the fixture, thereby significantly improving processing efficiency and accuracy. This flexibility not only reduces the time required for fixture replacement and adjustment, but also allows even less experienced operators to quickly master the usage method, thereby achieving rapid switching on the production line.
[0022] Reference Figure 3 and Figure 5 As shown in this embodiment: both ends of the second adjusting component 9 are provided with sliding grooves 14, and both ends of the stretching groove 8 are provided with sliding blocks 15. The surface of the sliding block 15 is slidably connected to the inside of the sliding groove 14. By moving the sliding block 15 inside the sliding groove 14, the movement of the second adjusting component 9 inside the stretching groove 8 can be made more stable, while limiting the movement position of the second adjusting component 9.
[0023] Reference Figure 4 As shown in this embodiment: one end of the limiting rod 12 is fixedly connected to the connecting plate 16, and the surface of the limiting rod 12 is slidably connected to the first spring 17. One end of the first spring 17 is fixedly connected to the connecting plate 16, and the other end of the first spring 17 is fixedly connected to the inside of the first moving groove 10. By setting the first spring 17, the elasticity of the first spring 17 abuts against the connecting plate 16, so that the connecting plate 16 drives the limiting rod 12 and stabilizes it inside the limiting groove 13 without easily coming out.
[0024] Reference Figure 4As shown in this embodiment: guide grooves 18 are provided on both sides of the surface of the limiting rod 12, and guide blocks 19 are fixedly connected to both sides of the first moving groove 10. The surface of the guide block 19 is slidably connected to the inside of the guide groove 18. By moving the guide block 19 inside the guide groove 18, the movement of the limiting rod 12 can be guided, so that the limiting rod 12 can move along a predetermined route and accurately enter the inside of the second moving groove 11 and the limiting groove 13.
[0025] Reference Figure 4 As shown in this embodiment: a rotating shaft 20 is rotatably connected to one side of the first adjusting component 7, and the other side of the rotating shaft 20 is fixedly connected to the adjusting disk 6. Two structural grooves 21 are opened on one side of the first adjusting component 7. A second spring 22 is fixedly connected inside the structural groove 21. A limit button 23 is fixedly connected to one side of the second spring 22. Several adjusting grooves 24 are opened on the surface of the adjusting disk 6. The adjusting grooves 24 are arranged in a circle on the surface of the adjusting disk 6. The surface of the limit button 23 is slidably connected to the inside of the adjusting groove 24. By moving the limit button 23, the limit button 23 is moved out from the inside of the adjusting groove 24 and back into the inside of the structural groove 21, which can quickly release the limit between the first adjusting component 7 and the adjusting disk 6. At this time, the first adjusting component 7 can be rotated by the rotating shaft 20 to adjust the angle of the first adjusting component 7 or flip it. After the adjustment is completed, the elasticity of the second spring 22 will abut against the limit button 23 and enter the inside of the adjusting groove 24, so that the first adjusting component 7 completes the limit again.
[0026] Reference Figure 4 As shown in this embodiment: the surface of the limit button 23 is fixedly connected to the limit piece 25, and the surface of the limit piece 25 is slidably connected to the inside of the structural groove 21. By setting the limit piece 25, the limit button 23 can be stably placed inside the structural groove 21, ensuring that the limit button 23 will not be dislodged from the inside of the structural groove 21 due to external force or excessive elasticity of the second spring 22, thus ensuring the stability of the limit between the first adjusting component 7 and the adjusting plate 6.
[0027] Reference Figure 4 and Figure 5 As shown in this embodiment, magnets 26 are installed on the surface of the first adjustment component 7 and at the top and bottom of one side of the second adjustment component 9. By setting the magnets 26, the connection between the angle block and the first adjustment component 7 and the second adjustment component 9 can be made more stable and tighter, which can effectively prevent the angle block from moving or falling off during the processing, thereby improving the processing accuracy and safety.
[0028] Working principle: Step 1, by moving the limiting rod 12 out of the limiting groove 13, the limiting of the second adjusting component 9 is released. According to the size of the angle block, the length of the second adjusting component 9 is adjusted. After the adjustment is completed, the limiting rod 12 is moved back into the limiting groove 13 to complete the limiting of the second adjusting component 9 again. The sliding block 15 moves in the sliding groove 14 to ensure the stability of the second adjusting component 9 in the stretching groove 8 and limit its movement position. The elasticity of the first spring 17 abuts against the connecting plate 16, so that the limiting rod 12 is stable in the limiting groove 13 and is not easy to fall off. The guide block 19 moves in the guide groove 18 to provide guidance for the movement of the limiting rod 12 and ensure that it accurately enters the second moving groove 11 and the limiting groove 13.
[0029] Step two: Move the limit button 23 out of the adjustment groove 24 and back into the structural groove 21, thereby quickly releasing the limit between the first adjustment component 7 and the adjustment disk 6. Rotate the first adjustment component 7 through the rotating shaft 20 to adjust the angle or flip it. After the adjustment is completed, the elasticity of the second spring 22 abuts against the limit button 23, causing it to enter the adjustment groove 24 and re-complete the limit of the first adjustment component 7. Set the limit piece 25 to ensure that the limit button 23 is stable inside the structural groove 21 and prevent it from detaching due to external force or excessive elasticity of the second spring 22. Set the magnet piece 26 to make the connection between the angle block and the first adjustment component 7 and the second adjustment component 9 more stable and tight.
