Problems solved by technology

[0003] In production, we often encounter the processing of various large and special-shaped holes, such as large circular arc holes, large conical holes, etc. Since ordinary boring machines can only process cylindrical holes, they do not have the function of processing these holes, so forming tools or machining centers are used to process Processing, because the processing equipment of the processing center is expensive, the corresponding processing cost is high

Embodiment 1

[0035] Embodiment 1: as Figure 1-7 As shown, a tool holding device for boring special-shaped holes, including a holding body 1, a mandrel 2, a locking screw plug 3, an end cover 4, a tool holder 5, a tool 6, an adjusting screw plug 7 and an adjusting Base 8; the upper end of the clamping body 1 is a Morse cone 101, and the lower end is a cylindrical accommodation body 102, and the side of the accommodation body 102 is provided with at least one sliding sleeve 103, and the sliding sleeve 103 is provided with a first A through hole, the lower end of the Morse outer cone 101 is provided with a first blind hole connected with the inner cavity of the housing body 102, and a long compression spring 9 is provided in the first blind hole; the mandrel 2 includes two sections, the upper and the lower, The lower end of the long compression spring 9 abuts against the top of the upper section 201 of the mandrel, the bottom of the accommodating body 102 is provided with a second through ho...

Embodiment 2

[0036]Embodiment 2: This embodiment is a further improvement of Embodiment 1. The main improvement is that the fine adjustment of the extension length of the cutter 6 cannot be realized when Embodiment 1 is in use; and in this embodiment, the above-mentioned defects can be avoided. Specifically:

[0037] The third blind hole is provided with an adjusting rod 15 for adjusting the protruding length of the tool 6. The adjusting rod 15 is cylindrical and is slidably fitted with the third blind hole. One end of the adjusting rod 15 is in contact with the tail end of the tool 6. The other end of the adjustment rod 15 is provided with a chamfer, and the chamfer is in contact with the conical surface of the hexagonal cone end adjustment bolt 14; when the present embodiment is in use, the third blind hole is provided with an adjustment device for adjusting the protruding length of the cutter 6. Rod 15, under the action of chamfering down the length adjusting rod 15 by utilizing the hex...

Abstract

The invention discloses a cutter clamping device for boring irregularly-shaped holes. The cutter clamping device comprises a clamping body, a mandrel, locking screw plugs, an end cover, a cutter sleeve, a cutter, an adjusting screw plug and an adjusting base, wherein a mohs outer cone is arranged at the upper end of the clamping body, a cylindrical accommodating body is arranged at the lower end of the clamping body, and one or more sliding sleeves are arranged on the side of the accommodating body; the mandrel comprises an upper segment and a lower segment, and the lower end of a long compression spring is abutted against the top end of the upper segment of the mandrel; a second through hole is formed in the bottom of the accommodating body; the end cover is connected to the lower openingof the second through hole; a guiding mechanism A is arranged between the lower segment of the mandrel and the end cover; the cutter sleeve is in the shape of a step, and the cutter is in dismountable and inserting connection to the cutter sleeve; the locking screw plugs cooperate with internal threads in the top end of the sliding sleeve; a spherical contact is arranged at the upper part of theend surface of the tail end of the cutter sleeve, and is in contact with the profiling surface of the upper segment of the mandrel; and a guiding mechanism B is arranged between the cutter sleeve andthe sliding sleeve. The cutter clamping device disclosed by the invention is simple, scientific and reasonable in structure, high in processing precision and low in designing and manufacturing cost, and is convenient for processing of the irregularly-shaped holes.

Description

technical field [0001] The invention relates to the technical field of machining equipment, in particular to a tool clamping device for boring special-shaped holes. Background technique [0002] Boring refers to the further processing of forged, cast or drilled holes. Boring can enlarge the aperture, improve precision, reduce surface roughness, and can better correct the deviation of the original hole axis. [0003] In production, we often encounter the processing of various large and special-shaped holes, such as large circular arc holes, large conical holes, etc. Since ordinary boring machines can only process cylindrical holes, they do not have the function of processing these holes, so forming tools or machining centers are used to process Processing, because the processing equipment of the processing center is expensive, the corresponding processing cost is high. [0004] Therefore, it is necessary to invent a tool holding device for boring special-shaped holes to sol...
