Abstract
Description
Technical Field
[0001] This utility model relates to the field of tooling and fixture technology, specifically to a multi-angle machining fixing fixture. Background Technology
[0002] A machine tool fixture is a device used on a machine tool to clamp workpieces and guide cutting tools. Its function is to position the workpiece so that it obtains the correct position relative to the machine tool and cutting tools. During the machining of the workpiece, it can keep the workpiece in a stable state, so that the machining mechanism on the machine tool can process it.
[0003] Traditional clamping systems use rigid constraints to fix the workpiece, creating a rigid coupling between its spatial position and the machining reference surface. This prevents dynamic adjustment of the workpiece's orientation during the machining cycle. This static clamping mode severely restricts the reconfigurability of the workpiece's spatial orientation during multi-process machining. In complex machining scenarios that require changing the machining reference surface, operators cannot adjust the workpiece's spatial orientation in real time according to process requirements.

[0013] The present invention will be further described below with reference to the accompanying drawings.
[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.
[0015] See Figure 1-2A multi-angle machining fixing fixture includes a mounting base 1, bearing columns 2 on the left and right sides of the mounting base 1, a rotating shaft 3 between the bearing columns 2, a bearing column extending from any end of the rotating shaft 3 and a rotating handle 4, a base 5 movably sleeved on the rotating shaft 3, the base 5 and the mounting base 1 forming a cross-shaped structure in space, a pair of bearing seats 6 on the base 5, a positive and negative lead screw 7 between the bearing seats 6, sliding plates 8 on the left and right sides of the positive and negative lead screw 7, a sliding groove 9 on the upper surface of the base 5, a slider 10 at the bottom of the sliding plate 8 matching the sliding groove 9, a clamping plate 11 on the inner wall of the sliding plate 8, and a bearing seat extending from one end of the positive and negative lead screw 7 and a rotating disk 12. Specifically, the component is placed between two clamping plates 11, and the two sliding plates 8 are moved relative to each other by rotating the forward and reverse lead screws 7, thereby clamping and fixing the component through the clamping plates 11. By rotating the rotating shaft 3, the angle of the base 5 is adjusted, which means adjusting the machining reference surface of the component. At the same time, the base 5 can slide left and right along the rotating shaft 3 to adjust its position. In summary, by setting a base that can move and rotate laterally, the clamping plates can be adjusted laterally and at an angle after clamping the component, and the machining reference surface can be adjusted, improving practicality and flexibility.
[0016] In this embodiment, fastening devices 13 are provided on the left and right sides of the base 5. The fastening devices 13 are mainly used to fix the base after adjusting its lateral position.
[0017] In this embodiment, the fastening device 13 includes a locking sleeve 131 and a locking nut 132. The locking sleeve 131 has a tapered structure and external threads, and equidistant grooves 133 are formed on its exterior. The locking nut 132 is threadedly connected to the external threads. As the locking nut 132 rotates, the presence of the grooves 133 compresses the locking sleeve 131, allowing it to fit tightly against the rotating shaft 3, thereby fixing the base 5.
[0018] In this embodiment, an auxiliary fixing device 14 is provided on the rotating shaft 3. The auxiliary fixing device 14 is mainly used to assist in positioning and fixing the rotation angle of the base.
[0019] In this embodiment, the auxiliary fixing device 14 includes a driving gear 141, a driven gear 142, a short shaft 143, and a bearing 144. The driving gear is sleeved on the rotating shaft, the short shaft is disposed inside the driven gear, and the bearing is disposed on the side of the bearing post. One end of the rotating shaft is embedded in the bearing, and the driving gear and the driven gear are meshed and connected for transmission. The meshing transmission between the driving gear 141 and the driven gear 142 increases their friction and prevents excessive rotation when adjusting the base angle, which would affect its use.
[0020] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
