Description

Technical Field

[0001] This utility model relates to a floating device for improving the reaming accuracy of a reamer, belonging to the field of machining technology. Background Technology

[0002] In the machining of spare parts, it is often necessary to machine sleeve-type parts with internal diameters ranging from Φ8+0.02 to Φ30+0.02 mm. Due to the small hole size and tight tolerances, the only way to meet the technical requirements is to use a reamer. The conventional method is to install the reamer in a Morse taper sleeve, which is then mounted on the tailstock of a lathe. However, this method results in the reamer being fixed without clearance and cannot be aligned properly, leading to holes that are too large or have elliptical defects. For small and medium-sized enterprises using outdated equipment, the product quality and precision simply cannot meet the technical requirements. At the same time, severe damage to the reamer increases production costs. Utility Model Content

[0003] The technical problem to be solved by this utility model is that the existing reamer is directly fixed to the Morse taper, which results in the reamer being fixed without gap and unable to be aligned, and the hole diameter reamed by the reamer is too large or has elliptical defects.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a floating device for improving the reaming accuracy of a reamer, comprising a floating sleeve and a Morse cone, wherein one end of the floating sleeve is provided with a Morse cone hole, and the other end is inserted into the mounting hole of the Morse cone and is spaced apart from the inner wall of the Morse cone.

[0005] In the above structure, the gap between the floating sleeve and the Morse taper is 0.05mm to 0.15mm.

[0006] Furthermore, the gap between the floating sleeve and the Morse taper in the above structure is 0.09mm to 0.11mm.

[0007] In the above structure, the floating sleeve and the Morse taper are fixed together by a pin.

[0008] Furthermore, the above structure also includes a pin, through which the floating sleeve is connected to the Morse taper.

[0009] Furthermore, in the above structure, the mounting hole sidewall of the Morse taper is provided with a through external hole in the radial direction, and the floating sleeve is provided with a through internal hole in the radial direction at the end away from the Morse taper hole. The small end of the pin is inserted into the through external hole on one side and extends to the internal hole before exiting through the through external hole on the other side.

[0010] The beneficial effects of this utility model are: the device has a simple structure, is easy to install, and is low in cost. This device uses a pin to connect the floating sleeve to the Morse taper, with the floating sleeve and the Morse taper spaced apart. When machining sleeve-type parts, the reamer can automatically align the hole diameter, ensuring that the reamed hole diameter meets technical requirements without being too large or having elliptical defects. This provides sufficient assurance for the dimensional accuracy of the inner hole machining of sleeve-type parts while saving production costs. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figures 1 to 3 As shown, this utility model discloses a floating device for improving the reaming accuracy of a reamer, comprising a floating sleeve 2 and a Morse taper 1. One end of the floating sleeve 2 has a Morse taper hole 21, and the other end is inserted into the mounting hole 11 of the Morse taper 1, spaced apart from the inner wall of the Morse taper 1. Those skilled in the art will understand that this structure overcomes the limitations of existing methods where the reamer is directly installed in the Morse taper sleeve, and then the Morse taper sleeve is installed on the lathe tailstock. This installation method results in the reamer's position being fixed and unable to be aligned, causing the reamed hole diameter to be too large or to have elliptical defects. This structure introduces a floating sleeve 2. Specifically, the floating device includes a floating sleeve 2 and a Morse taper 1. One end of the floating sleeve 2 has a Morse taper hole 21 for fixing the reamer, while the other end of the floating sleeve 2 is inserted into the mounting hole 11 of the Morse taper 1, connecting the floating sleeve 2 to the Morse taper 1. The Morse taper sleeve is mounted on the tailstock of a lathe, with the floating sleeve 2 spaced apart from the inner wall of the Morse taper 1. This structural arrangement ensures a certain gap between the installed floating sleeve 2 and the Morse taper 1, specifically 0.05mm to 0.15mm. This allows the reamer to automatically align with the hole diameter during machining of sleeve-type parts, ensuring the reamed hole diameter meets technical requirements without over-sized or elliptical defects.

[0017] Preferably, the gap between the floating sleeve 2 and the Morse taper 1 in the above structure is 0.05mm to 0.15mm. Those skilled in the art will understand that the floating sleeve 2 in this structure only requires a slight movement to automatically align the reamer; therefore, the gap between the floating sleeve 2 and the Morse taper 1 is preferably 0.05mm to 0.15mm.

[0018] Preferably, the gap between the floating sleeve 2 and the Morse taper 1 in the above structure is 0.09mm to 0.11mm. Those skilled in the art will understand that this structure further limits the gap between the floating sleeve 2 and the Morse taper 1 to 0.09mm to 0.11mm to allow the floating sleeve 2 to move only slightly to automatically align the reamer, thus preventing damage to the reamer from direct mounting on the Morse taper sleeve.

[0019] Preferably, in the above structure, the floating sleeve 2 and the Morse cone 1 are fixedly connected by a pin. Those skilled in the art will understand that, for ease of connection between the floating sleeve 2 and the Morse cone 1, this structure preferably uses a pin to fix the floating sleeve 2 and the Morse cone 1.

[0020] Preferably, the above structure further includes a through pin 3, through which the floating sleeve 2 and the Morse taper 1 are connected. Those skilled in the art will understand that this structure further specifies the through pin 3 as the connecting pin, so that the floating sleeve 2 and the Morse taper 1 are connected through the through pin 3.

[0021] Preferably, in the above structure, the mounting hole 11 of the Morse cone 1 has a through hole 12 radially provided on the side wall, and the floating sleeve 2 has a through hole 22 radially provided at the end away from the Morse cone hole 21. The small end of the pin 3 is inserted through the outer hole 12 on one side, extends to the inner hole 22, and then exits through the outer hole 12 on the other side. Those skilled in the art will understand that, in order to facilitate the insertion of the pin 3 and the connection between the floating sleeve 2 and the Morse cone 1, this structure preferably has a through hole 12 radially provided on the side wall of the mounting hole 11 of the Morse cone 1, and a through hole 22 radially provided at the end of the floating sleeve 2 away from the Morse cone hole 21. This allows the small end of the pin 3 to be inserted through the outer hole 12 on one side, extend to the inner hole 22, and then exit through the outer hole 12 on the other side, thus achieving the connection between the floating sleeve 2 and the Morse cone 1 via the pin 3.
