AI Technical Summary
Existing fixtures for machining tubular parts require constant adjustment of the pipe angle when machining circumferential structures, resulting in low machining efficiency.
A high-precision mechanical parts processing fixture was designed, which adopts a combination structure of slide rail, base fixing frame, non-closed arc disk and concentric clamping arm. The precise positioning and rotation of the pipe is achieved by bolt fastening and screw pair adjustment. Combined with the use of guide pin and clamping bearing, the pipe is ensured to be processed with the axis as the rotation axis.
It enables high-precision clamping and rotation of tubular parts, improving processing efficiency and simplifying the adjustment process.

[0004] A high-precision mechanical parts processing fixture includes a slide rail, on which a base fixing frame is fastened and clamped by bolts. A non-closed arc disk is fixed on the base fixing frame, and at least three concentric clamping arms are arranged on the non-closed arc disk.
[0005] The concentric clamping arm is adjusted by a screw pair, and the front end of the concentric clamping arm is provided with a rotating component, the axis of which is coaxial with the central axis of the non-closed arc disk.
[0006] Preferably, a bottom clamping frame is fixed to the base fixing frame by bolts, and the bottom clamping frame clamps and fixes the non-closed arc disk.
[0007] Preferably, the non-closed arc disk is provided with three reference plates and three guide pins at intervals, and also includes three guide frames with sliding grooves. The upper end of the guide frame is rotatably provided with a hand-tightening adjusting bolt, which is threadedly connected to the reference plate. The guide pin passes through the sliding groove and guides the sliding groove when the guide frame moves.
[0008] Preferably, the lower end of the guide frame is rotatably provided with a clamping bearing, which clamps the outside of the part being processed.
[0009] Preferably, two of the guide frames on the non-closed arc disk are symmetrically located on the lower side, and the other guide frame is located directly above.
[0010] Preferably, the non-closed arc disk, the bottom clamping frame, the base fixing frame, and the accessories disposed on the non-closed arc disk are provided in two sets.
[0011] The advantages and positive effects of this utility model are:
[0012] 1. High clamping accuracy; it can clamp and fix tubular parts to restrict their axial movement and ensure that they can rotate around the axis, which is convenient for circular machining.
[0013] 2. The structure is simple and easy to adjust. Attached Figure Description
