[0031] In the embodiment, as Figures 1-7As shown, the utility model provides a tool fixture for CNC processing, including mainboard 1, mainboard integral moulding, mainboard top surface array distribution positioning block 2, limit block 3 and positioning groove 4, limit groove 5 is equipped between adjacent limit block, limit strip 6 is installed in limit groove, guide rail 7 is installed in both ends in positioning groove, slider 8 is inserted with corresponding guide rail, shovel 9 bottom side surface and the one side of slider towards positioning groove center abut, by locking bolt 10 shovel and mainboard are connected, by slider, positioning block and limit block workpiece both sides are locked, by limit strip workpiece 11 one end is limited, another end of workpiece is processed through cutter.

[0032] In this example, because the workpiece is locked by the slider, positioning block and limit block on both sides, and the slider can be fine-tuned along the guide rail, the workpiece size is not fixed, and the workpiece width meets the conditions.

[0033] In this embodiment, the positioning block and the limit block are higher than the top surface of the main plate, and the positioning groove is lower than the top surface of the main plate.

[0034] In this embodiment, the positioning groove is provided with a positioning hole 401 at both ends, the guide rail is provided with a guide rail hole 701 in the middle, and the connecting bolt is sequentially inserted through the guide rail hole and the positioning hole to connect the guide rail and the main plate.

[0035] In this embodiment, the guide rail is inverted trapezoidal, the cross-sectional area of the top surface of the guide rail is larger than that of the bottom surface, and the top surface of the guide rail is higher than the top surface of the main plate.

[0036] In this embodiment, the bottom of the slider is provided with an inverted trapezoidal groove 801, the inverted trapezoidal groove is matched with the top of the guide rail, and the bottom of the slider abuts against the top surface of the main plate.

[0037] In this example, the guide rail is inverted trapezoidal and the slider inverted trapezoidal groove is set to insert the slider into the guide rail, so that the slider can only move horizontally along the guide rail and cannot be separated vertically, avoiding the loosening of the slider from the guide rail and the failure to clamp the workpiece, improving the stability of clamping.

[0038] In this embodiment, the side of the slider towards the center of the positioning groove is a slider inclined surface end, the inclined surface end abuts against the bottom side surface of the shovel, and the side of the inclined surface slider away from the center of the positioning groove is a slider flat end, and the flat end abuts against the side surface of the workpiece.

[0039] In this embodiment, the positioning groove is provided with a positioning hole 402 in the middle, the shovel is provided with a shovel hole 901 in the middle, and the locking bolt is sequentially inserted through the shovel hole and the positioning hole to connect the shovel and the main plate.

[0040] In this embodiment, the shovel is inverted trapezoidal, the cross-sectional area of the top surface of the shovel is larger than that of the bottom surface, and the bottom side surface of the shovel abuts against the inclined surface end of the slider.

[0041] Example 2:

[0042] In this embodiment, as Figures 1-7 As shown, based on Example 1, the size of the positioning block is larger than that of the limiting block. The groove between the positioning block and the limiting block is the first limiting groove, which is suitable for clamping and processing workpieces with shorter dimensions. Limiting grooves are provided between adjacent limiting blocks. By observing the overall size of the workpiece, a suitable limiting groove is selected. At the same time, a suitable positioning groove also needs to be selected. At least two positioning grooves are selected to improve the stability of clamping.

[0043] In this embodiment, the motherboard is further configured with a support column 12 at the bottom. The support column can be connected to the motherboard by bolts or welding. The support column can support the load, adjust the level and reduce shock. At the same time, since the motherboard does not directly contact the space below, it can reduce the amount of dirt contamination to a certain extent.

[0044] The working process of this CNC machining fixture is as follows: First, determine the overall dimensions of the workpiece, then select a suitable limiting groove. Insert the limiting strip into the limiting groove, and place the end of the workpiece that does not need to be machined against the limiting strip. At the same time, place the side of the workpiece against the positioning block and the limiting block. Place the guide rail into the positioning groove, aligning the guide rail hole with the first positioning hole. Connect the guide rail to the main board by passing the connecting bolts through the guide rail hole and the first positioning hole in sequence. Insert the slider into the corresponding guide rail. Place the shovel on the slider, aligning the shovel hole with the second positioning hole. Connect the shovel to the main board by passing the locking bolts through the shovel hole and the second positioning hole in sequence. Adjust the depth of the locking bolts until the flat end of the slider locks both sides of the workpiece with the positioning block and the limiting block. The workpiece positioning is completed. The tool then machines the other end of the workpiece to create an oil groove. Since multiple sides of the workpiece need to be machined, when the workpiece is flipped, simply loosen the locking bolts and move the slider to remove the workpiece. After flipping the workpiece, tighten the locking bolts again and repeat the process until the workpiece machining is completed.
