[0017] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0018] like Figure 1-2As shown, this utility model discloses a high-speed multi-faceted machining fixture, comprising a base 1 and a fixture 2 mounted on the base. The base 1 is mounted on a four-axis machine tool and also includes a cylinder 3 located at the lower part of the base 1. The fixture 2 includes a tooling base 21 and a slider 22. The tooling base 21 has a double-layer structure. The upper surface of the tooling base 21 is provided with multiple mold cavities 23 for placing workpieces. The mold cavities 23 are arranged in pairs, and a groove 24 for placing the slider 22 is provided between the two mold cavities 23. The slider 22 is enclosed in... The device includes side sliders 221 and push plates 222 on both sides, and a side top slider 223 in the middle. The side sliders 221 and push plates 222 are connected as one unit. A limiting block 224 is provided on the outer side of the push plate 222. The outer side of the limiting block 224 is in contact with the positioning surface of the workpiece 4. The inner side of the side slider 221 is a slope and the outer side is a plane. Both sides of the side top slider 223 are slopes, which are adapted to the inner side of the side slider 221. The slider 22 is fixed in the groove 24 by fixing screws 26.

[0019] This utility model discloses a high-speed multi-faceted machining fixture, mainly comprising a base 1, a clamp 2, and a cylinder 3. The clamp 2 is mounted on the base 1 and is used to limit the workpiece 4. The cylinder 3 is mounted on the bottom side of the base 1 and is used to lock the tooling base 21. The base 1 is mounted on a four-axis machine tool, including an X-axis, a Y-axis, a Z-axis, and a rotary axis, enabling the base 1 to move the workpiece on it in the left-right, up-down, and front-back directions, and also to rotate, ensuring that multiple faces of the workpiece can be machined.

[0020] Specifically, the fixture 2 includes a tooling base 21 and a slider 22. The tooling base 21 has a double-layer structure. The upper layer is provided with multiple sets of mold cavities 23 for placing workpieces 4, and the lower layer is connected to the base 1. A groove 24 for placing the slider 22 is provided between the two mold cavities 23. The lower part of the workpiece 4 is placed in the mold cavity 23 and is limited and pressed by the slider 22. The upper part is exposed outside the mold cavity 23 for machining screw holes on the bottom and side walls of the workpiece 4. The slider 22 includes two side sliders 221, two push plates 222, and a side top slider 223. The side sliders 221 and push plates 222 on the same side are connected as one piece by screws. The outer side of the push plate 222 is also provided with a limiting block 224 that contacts the positioning surface of the workpiece 4. The limiting block 224 protrudes outward to hold the workpiece 4. Since the inner side of the side slider 221 is a slope and the outer side is a plane, and both sides of the side top slider 223 are slopes, when the side top slider 223 is installed between the two side sliders 221 from top to bottom, the side top slider 223 will push the two side sliders 221 outward and slide them. At the same time, it will drive the two push plates 222 to slide outward. The limiting block 224 on the outer side of the push plate 222 will contact the outermost side of the workpiece 4. At this time, it will hold the side of the workpiece 4 to position it, further ensuring the stability of the workpiece processing.

[0021] In a preferred embodiment, refer to Figure 1 and 2The base 1 of this rapid multi-faceted machining fixture has a circular hole on its surface. The telescopic rod of the cylinder 3 passes through the circular hole and connects to the lower part of the fixture base 21. The lower part of the fixture base 21 has mounting holes 211 at both ends. The mounting holes 211 are elliptical, and the inner wall of the mounting holes 211 has a U-shaped limiting platform 212 corresponding to the circular hole. The diameter of one end of the elliptical hole is larger than the diameter of the other end with the U-shaped limiting platform 212. The fixture base 21 is fixed to the base 1 by a positioning pin 25. The positioning pin 25 passes through the elliptical hole and the circular hole to the front end of the telescopic rod of the cylinder 3 and connects to the telescopic rod.

[0022] When the workpiece base 21 needs to be removed, the telescopic rod of the cylinder 3 extends upward, causing the positioning pin 25 to move upward. Then, the workpiece base 21 is moved away from the U-shaped limiting platform 212, allowing the workpiece base 21 to be removed as a whole for easy material replacement. It should be noted that the diameter of the mounting hole 211 is slightly larger than the outer diameter of the positioning pin, so that the positioning pin can be disengaged from the mounting hole 211. When the workpiece base 21 needs to be installed and positioned, first, the two ends of the workpiece base 21 are inserted into the positioning hole 211, then the workpiece base 21 is pushed to the end close to the U-shaped limiting platform 212, and then the cylinder is activated, causing the telescopic rod of the cylinder 3 to retract downward. This fixes the workpiece base 21 on the base 1, ensuring convenient loading and unloading of materials by the fixture.

[0023] In a preferred embodiment, refer to Figure 1 and 2 The high-speed multi-faceted machining fixture has a screw hole in the center of the groove 24. The width of the groove 24 is greater than the width of the slider 22. By providing a screw hole in the center of the groove 24, the fixing screw 26 in the center of the side top slider 223 can be lowered, allowing the side top slider 223 to push the side slider 221 to move to both sides. It should be noted that the height of the side top slider 223 is less than the height of the side slider 221, ensuring that the side top slider 223 has enough space to move downwards, thereby pushing the side slider 221 to move to both sides. By setting the width of the groove 24 to be greater than the width of the slider 22, it is ensured that the slider 22 can change its overall width according to the position of the workpiece.

[0024] In a preferred embodiment, refer to Figure 1 and 2 The workpiece 4 on the fixture has a first screw hole 41 on its bottom and a second screw hole 42 on its side wall, with two of each. Multiple holes are provided on the side and bottom surfaces of the workpiece 4, ensuring that screw holes on multiple surfaces can be machined under the drive of the four axes.

[0025] This high-speed, multi-faceted machining fixture also has the following features:

[0026] 1. By using specialized clamps, products can be clamped quickly, further improving clamping efficiency.

[0027] 2. By utilizing the slider, clamping deviation is prevented, further improving clamping accuracy.

[0028] 3. The pin-positioning fixture achieves a quick clamping effect, further ensuring the reliability and stability of the clamping.

[0029] 4. By using interchangeable special fixtures, rapid processing can be achieved, further improving processing efficiency.

[0030] This application differs from the traditional single-clamping machining process of vises, greatly improving the convenience and stability of clamping products. Through verification and testing, the fixture of this application can process multiple workpieces at the same time and can ensure the stability of the machining process.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
