Description

Technical Field

[0001] This invention relates to the field of high-precision reaming, and specifically to a universal floating hinge sleeve. Background Technology

[0002] Floating reamers are used on boring and milling machines, CNC machining centers, or mill-turning centers for high-precision reaming operations. The reamer itself cannot float; instead, it floats within a floating reamer holder. This holder employs a specially designed mechanism that allows it to float parallel to the axial direction, or at an angle in the vertical space, or both, to compensate for errors in the horizontal or vertical direction caused by machine tool thermal deformation, workpiece mounting, or the reamer itself. However, existing reamers suffer from several drawbacks: they cannot provide relatively stable rigidity, leading to excessively large ranges of motion that may result in the reamer not entering the hole; and their overly complex structures make them difficult to manufacture. Summary of the Invention

[0003] The purpose of this invention is to solve the problems of existing tool sleeves, which cannot provide relatively stable rigidity, resulting in excessive range of motion and the possibility of not being able to fit into the hole, and whose structure is too complex to be manufactured, and thus to provide a universal floating hinge sleeve.

[0004] The technical solution of this invention is:

[0005] A general-purpose floating hinge sleeve includes a tool connecting part 1, a tool holder connecting part 2, a hinge sleeve connecting flange 3, and multiple hinge sleeve connecting parts 4. Both the tool connecting part 1 and the tool holder connecting part 2 are circular rod-shaped structures. The upper part of the tool connecting part 1 has a first cylinder 101 and a second cylinder 102 arranged coaxially from bottom to top along the circumferential direction. The lower end face of the tool holder connecting part 2 has a first circular hole 201 and a second circular hole 202 that match the first cylinder 101 and the second cylinder 102 from bottom to top along the axial direction. The first cylinder 101 and the second cylinder 102 of the tool connecting part 1 are respectively inserted into the first circular hole 201 and the second circular hole 202. The hinge sleeve connecting flange 3 is sleeved in the middle of the tool connecting part 1. The upper surface of the hinge sleeve connecting flange 3 abuts against the lower surface of the first cylinder 101. The hinge sleeve connecting flange 3 is connected to the bottom of the tool holder connecting part 2 through multiple hinge sleeve connecting parts 4.

[0006] Furthermore, the hinge sleeve connector 4 is a hinge sleeve connecting bolt, and the lower surface of the tool holder connecting part 2 has multiple axial connecting threaded holes evenly arranged in the circumferential direction. The hinge sleeve connecting flange 3 is provided with multiple axial connecting circular through holes that correspond one-to-one with the multiple axial connecting threaded holes. The hinge sleeve connecting flange 3 is connected to the bottom of the tool holder connecting part 2 through multiple hinge sleeve connecting bolts.

[0007] Furthermore, an inner waist-shaped hole 103 is machined radially on the side of the second cylinder 102, the center line of which is arranged perpendicularly to the axis of the second cylinder 102. An outer waist-shaped hole 203 is machined radially on the side of the tool holder connecting part 2, the outer waist-shaped hole 203 is perpendicularly connected to the second round hole 202, and the outer waist-shaped hole 203 is arranged correspondingly to the inner waist-shaped hole 103.

[0008] Furthermore, a cuboid protrusion 104 is provided axially at the center of the upper surface of the second cylinder 102, and a rectangular groove 204 matching the cuboid protrusion 104 is provided radially at the center of the bottom surface of the second circular hole 202 of the tool holder connecting part 2, and the cuboid protrusion 104 is inserted into the rectangular groove 204.

[0009] Furthermore, a tool mounting tapered hole 105 is provided at the center of the lower surface of the tool connecting part 1 along the axial direction, and the inner diameter of the tool mounting tapered hole 105 decreases sequentially from bottom to top.

[0010] Furthermore, the upper part of the tool holder connecting part 2 is provided with a coaxially arranged floating reamer 205 along the axial direction. The floating reamer 205 has a frustum-shaped structure, and the outer diameter of the floating reamer 205 decreases from bottom to top.

[0011] Furthermore, a chamfered transition block 206 is provided at the upper center of the floating reamer 205.

[0012] Furthermore, the hinged flange 3 is an annular plate structure, and the inner hole of the hinged flange 3 is clearance-fitted with the lower part of the tool connection portion 1.
