Embodiment

[0032] A honing tool device with the function of processing non-circular special-shaped holes, which can be processed in the inner hole 10, such as figure 1 and figure 2 As shown, this example includes: tool body 1, wedge-shaped cutter expansion assembly 2, axial feed assembly 3, main oilstone seat 4, actuator group 5, compensation oilstone seat 6 with compensation oilstone installed, support rod 7, retraction Knife spring coil 8. The wedge-shaped tool expansion assembly 2 is installed on the inner wall of the tool body 1, and the tail is connected with the axial feed assembly 3. The bottom of the main oil stone seat 4 is connected with the wedge-shaped knife-expanding assembly 2, and the two ends are respectively pressed by the knife-retracting spring ring 8. The compensating oil stone seat 6, the actuator group 5, the support rod 7, and the knife retracting spring coil 8 form a compensating mechanism. The bottom of the compensating oilstone seat 6 and the bottom of the s...

Abstract

The invention relates to a honing cutter device with the function of machining a noncircular special-shaped hole. The honing cutter device comprises a cutter main body, wedge-shaped cutter tensioning components installed on the inner wall of the cutter main body, main oilstone bases connected with the wedge-shaped cutter tensioning components and a compensation mechanism composed of compensation oilstone bases, actuator sets, supporting rods and cutter retracting spring rings, wherein the tails of the wedge-shaped cutter tensioning components are connected with an axial feeding component. Compensation oilstones are installed on the compensation oilstone bases. The compensation oilstone bases and the supporting rods are connected with the actuator sets. The cutter retracting spring rings are pressed at the two ends of the compensation oilstone bases, the supporting rods and the main oilstone bases. Compared with the prior art, the honing cutter device has the function for precisely machining special-shaped inner holes, and precise honing machining of the complex special-shaped inner holes can be conducted through the compensation mechanism for the sections of the inner holes.

Description

technical field [0001] The invention relates to a precision inner hole processing tool, in particular to a honing tool device with the function of processing non-circular special-shaped holes. Background technique [0002] Precision machining of non-circular special-shaped inner holes is a kind of inner hole processing technology that is difficult to realize. The biggest difference between it and circular inner hole machining is that non-circular inner hole machining not only needs to control the size of the inner hole diameter of the part, but also Controls the contour accuracy of the inner bore of the part. Micro-feed mechanism is often used for high-precision non-circular cross-section machining, which is generally realized by elastic deformation, mechanical profiling, eccentric spindle or eccentric tool holder. This method has complex mechanism, difficult adjustment, low precision, high cost, and is difficult to popularize and apply. Moreover, the current non-circular ...
