Description

Technical Field

[0001] This application relates to the field of fixture technology, and in particular to a machining fixture. Background Technology

[0002] A machining fixture is a device used to clamp a workpiece (or guide a cutting tool) during machining. A machining fixture ensures the workpiece occupies the correct position within the fixture, guaranteeing a definite positional relationship between the workpiece and the machine tool, thereby ensuring dimensional and positional accuracy during machining. Simultaneously, it overcomes external forces such as cutting forces and gravity acting on the workpiece during machining, keeping it fixed in its position and preventing displacement or vibration, thus ensuring the stability and reliability of the machining process. Therefore, machining fixtures play a crucial role in mechanical manufacturing; they are essential process equipment for ensuring machining quality, improving production efficiency, and reducing production costs. However, current machining fixtures have limitations, particularly in their inconvenience in clamping and fixing workpieces of different sizes. Therefore, to address these issues, this application provides a machining fixture. Utility Model Content

[0003] To address the limitations of existing machining fixtures, this application provides a machining fixture.

[0004] This application provides a machining fixture, including a base, on which an adjustment assembly is provided. The adjustment assembly includes two side slides, with sliders movably connected inside the two side slides. Guide rails are fixedly connected to the tops of the two side sliders. Mounting holes are provided on the two side guide rails, with bolts installed inside the mounting holes. Grooves are symmetrically provided on both side guide rails. Movable seats are symmetrically movably fitted on both side guide rails. Locking knobs are installed on both side movable seats. Clamping blocks are symmetrically fixedly connected to both side movable seats.

[0005] Preferably, the base has through holes at all four corners of its top, and the through holes completely penetrate the base.

[0006] Preferably, the sliding grooves on both sides are symmetrically opened on the top of the base, and the sliding grooves on both sides are perpendicular to the guide rail.

[0007] Preferably, four movable seats are provided, which are arranged symmetrically in pairs, and each of the four movable seats is movably engaged with the grooves on both sides.

[0008] Preferably, four clamping blocks are provided, and all four clamping blocks are located inside the guide rails on both sides.

[0009] In summary, this application includes the following beneficial technical effects:

[0010] By designing an adjustment component, when using a machining fixture to fix the workpiece, the base is installed on the machining equipment through through holes. The device is then adjusted according to the required workpiece size. First, the two side guide rails are moved, allowing the sliders on both sides to move within their respective grooves. After the guide rails are moved to the corresponding positions, the sliders are locked to the guide rails using bolts inside the mounting holes. Then, the workpiece is placed between the two side guide rails, and the movable seats on the guide rails are moved to clamp the workpiece using multiple clamping blocks. Finally, multiple locking knobs are rotated to fix the clamping blocks. Compared to existing technologies, this design can clamp and fix workpieces of different sizes, facilitating the processing of workpieces of varying dimensions and improving the overall practicality and applicability of the device.

[0016] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0017] Example:

[0018] A machining fixture for clamping and fixing during machining, as shown in the reference. Figure 1 The device includes a base 1, which facilitates the installation of various components. The base 1 has through holes 2 at its four corners, which completely penetrate the base 1. The base 1 can be easily installed on the processing equipment through the through holes 2. The base 1 is equipped with an adjustment component 3, which facilitates the adjustment of the device, thereby facilitating the clamping and fixing of workpieces of different sizes.

[0019] During processing, the base 1 is installed on the processing equipment through the through hole 2, and the device is adjusted according to the adjustment component 3 to clamp and fix workpieces of different sizes.

[0020] Reference Figure 2 - Figure 4 The adjusting component 3 includes two side slides 4, which are symmetrically located on the top of the base 1. Slider 5s are movably connected inside the two side slides 4, allowing the slider 5s to move within the slides 4. Guide rails 6 are fixedly connected to the top of the sliders 5, allowing the guide rails 6 to move with the sliders 5. The two side slides 4 are perpendicular to the guide rails 6. Mounting holes 7 are provided on the two side guide rails 6, and bolts 8 are installed inside the mounting holes 7. The bolts 8 inside the mounting holes 7 facilitate the fixing of the sliders 5 and the guide rails 6. Grooves 9 are symmetrically provided on both side guide rails 6, allowing for easy movement. For the installation and subsequent movement of the seat 10, four movable seats 10 are symmetrically and movably sleeved on the two side guide rails 6. The four movable seats 10 are arranged symmetrically in pairs. All four movable seats 10 are movably engaged with the grooves 9 on both sides. Each movable seat 10 on both sides is equipped with a locking knob 11, which can be used to fix the movable seat 10. Each movable seat 10 on both sides is symmetrically and fixedly connected with a clamping block 12. There are four clamping blocks 12, which are all located inside the two side guide rails 6. The multiple clamping blocks 12 can be used to conveniently clamp and fix the workpiece.

[0021] During processing, the device is first adjusted according to the size of the workpiece to be processed. The guide rails 6 on both sides are moved so that the sliders 5 on both sides move inside the sliding grooves 4 on both sides. After the guide rails 6 are moved to the corresponding positions, the sliders 5 and the guide rails 6 are locked by the bolts 8 inside the mounting holes 7. Then the workpiece is placed between the guide rails 6 on both sides, and the movable seats 10 on the guide rails 6 on both sides are moved so that the multiple clamping blocks 12 clamp the workpiece. Finally, the multiple locking knobs 11 are rotated to fix the multiple clamping blocks 12.

The device is then adjusted according to the size of the workpiece to be machined. First, the guide rails 6 on both sides are moved so that the sliders 5 on both sides move inside the sliding grooves 4 on both sides. After the guide rails 6 are moved to the corresponding positions, the sliders 5 and the guide rails 6 are locked by the bolts 8 inside the mounting holes 7. Then, the workpiece is placed between the guide rails 6 on both sides, and the movable seats 10 on the guide rails 6 on both sides are moved so that multiple clamping blocks 12 clamp the workpiece. Finally, multiple locking knobs 11 are rotated to fix the multiple clamping blocks 12.
