Description

Technical Field

[0001] The utility model belongs to the technical field of five-axis machining, and in particular relates to a five-axis machining center parts machining fixture. Background Art

[0002] The five-axis machining center is an advanced CNC machine tool with five independent motion axes, including three linear coordinate axes (X, Y, Z axes) and two rotation axes (usually A axis and C axis). This machine tool can move in five independent axes, so that the workpiece can be cut and processed at multiple angles and directions.

[0003] When the existing five-axis machining center needs to process the main body of the part, the preliminary processing needs to be fixed in the five-axis machining center through a vise, and the existing vise pushes the two ends of the vise left and right by means of screws to clamp and fix the bottom of the part. Due to the different sizes of parts, when clamping them, it is necessary to slowly adjust the jaw spacing by turning the screw to avoid the jaws being too large to be conducive to clamping, or too small to fit into the jaws. At the same time, after clamping, the left and right screws need to be adjusted to adjust the part to the center position of the vise, which is not conducive to rapid positioning and clamping of the part. Utility Model Content

[0009] The support block is located below the limit block, the top of the limit block is in contact with the bottom of the slide, the bottom of the limit block is in contact with the top of the support block, and the fixing plate is offset from the support block.

[0010] The beneficial effect of the utility model is that the two slides can slide on the fixed frame, so that the fixed rod clamps the parts, and then the limit block is clamped between the bottom blocks, and at the same time the support block limits the bottom end surface of the bottom block, so that the limit block is limited in the bottom block, so that the parts clamped between the slides can be quickly adjusted to the center of the device, and then the position is limited by the threaded rod, so that the device can quickly adjust the parts to the middle position after installing the parts, which is convenient for the five-axis machining center to perform multi-axis machining on the parts.

After the fixing rod 23 clamps the parts, at this time, the bottom end of the bottom block 21 can be at a certain distance from the bottom end of the fixed frame 1, so that the limiting block 11 fixedly connected to one end of the support rod 12 can be pushed to the bottom of the bottom block 21, so that the support rod 12 is inserted upward to the inner wall of the bottom block 21. Since the limiting block 11 and the bottom block 21 are engaged and connected up and down, the limiting block 11 can be horizontally limited at the bottom The bottom block 21 can be horizontally slid synchronously with the limit block 11. At this time, in order to prevent the limit block 11 from sliding downward and separating from the bottom block 21, the support block 14 can be engaged with the inner wall of the fixing frame 1, so that the support block 14 is supported on the bottom end surface of the bottom block 21, and the bottom end surface of the bottom block 21 slides on the support block 14. At the same time, the limit block 11 is limited by the support block 14, so that the limit block 11 can be limited in the bottom block 21, so that the bottom block 21 can be limited by the limit block 11. At this time, the two support rods 12 can be pushed to push the bottom block 21 so that the parts clamped between the fixing rods 23 can be Under the push of the support rod 12, the part is adjusted to the center above the fixed frame 1, so that the device can temporarily clamp the part and adjust it to the center of the fixed frame 1, and then support the support rod 12 by rotating the threaded rod 16 threadedly connected on the fixed plate 15, so that the threaded rod 16 limits the position of the support rod 12. At this time, after the positions of the two support rods 12 are fixed, the position of the slide 2 can be limited and fixed, so that the part is clamped between the clamping blocks 231, so that the device can quickly adjust the part to the middle position after installing the part, which is convenient for the five-axis machining center to perform multi-axis machining effects on the part.

[0020] One end of the support rod 12 is fixedly connected to a top block 13, and the top block 13 is slidably connected to the inner wall of the fixed frame 1, and both ends of the fixed frame 1 are fixedly connected to side plates 141, and the fixed plate 15 is fixedly connected to the side plates 141; the top block 13 fixedly connected to one end of the support rod 12 is fixed to one end of the support rod 12, so that when the threaded rod 16 is rotated to the fixed plate 15, the position of the slide 2 can be controlled by supporting one side of the top block 13, and the top block 13 is slidably connected to the inner wall of the fixed frame 1, so that the top block 13 will not affect the sliding of the slide 2, and the side plates 141 are used to limit the installation of the support block 14, and at the same time enable the top block 13 to slide horizontally between the side plates 141, ensuring that the support rod 12 corresponds to the bottom block 21, and avoiding affecting the supporting force of the limit block 11 on the bottom block 21.

[0021] A slot 22 is provided at the top of the slide 2, and the bottom end of the fixing rod 23 is fixedly connected to an insert block 24 matching the slot 22. A matching socket 241 is provided on the insert block 24 of the slide 2, and an insert rod 25 is engaged with the inner wall of the socket 241; the slot 22 provided at the top of the slide 2 is used to connect with the insert block 24 fixedly connected to the bottom end of the fixing rod 23, so that the insert block 24 and the insert hole 241 provided on the slide 2 are communicated, so that the insert rod 25 limits the position of the insert block 24, so that the fixing rod 23 is installed and fixed on the slide 2, which is convenient for replacing the clamping block 231 that has been used for a long time, and avoiding wear caused by long-term use, which affects the clamping of parts.

[0023] The working principle and use process of the utility model are as follows: after the parts are clamped by two fixing rods 23, the parts are clamped so that the limit block 11 is horizontally limited between the bottom block 21, so that the bottom block 21 can slide horizontally synchronously with the limit block 11, so that the support block 14 is supported on the bottom end surface of the bottom block 21, and the bottom end surface of the bottom block 21 slides on the support block 14. At this time, the two support rods 12 can be pushed so that the two support rods 12 push the bottom block 21 so that the parts clamped between the fixing rods 23 can be adjusted to the center above the fixing frame 1 under the push of the support rods 12. The device can temporarily clamp the part and adjust it to the center of the fixed frame 1, and then support the support rod 12 by rotating the threaded rod 16 threadedly connected on the fixed plate 15, so that the threaded rod 16 can limit the position of the support rod 12. At this time, after the positions of the two support rods 12 are fixed, the position of the slide 2 can be limited and fixed, so that the part is clamped between the clamping blocks 231, so that the device can quickly adjust the part to the middle position after installing the part, which is convenient for the five-axis machining center to perform multi-axis machining effects on the part.
