Clamping device for fixing indexable blade

Abstract

The invention discloses a clamping device for fixing an indexable blade. The clamping device comprises a tool holder, a clamping piece, a clamping bolt and a compression spring, wherein an indexable blade installation part and a bolt installation hole are arranged on the tool holder; the clamping piece is arranged above the tool holder; a through hole is formed in the clamping piece; the clamping bolt is mounted in the through hole and is in threaded connection with the bolt installation hole; the compression spring is arranged between the tool holder and the clamping piece; a clamping piece matching inclined surface connected with the tool holder is arranged at the rear end of the clamping piece; a tool holder matching inclined surface connected with the clamping piece is arranged at the rear end of the tool holder; a pair of accommodating grooves are formed in the tool holder matching inclined surface; and rear protruded parts are mounted in the accommodating grooves. The clamping device overcomes the shortcomings in the prior art; guiding and limiting for the clamping piece in a blade installation process are eliminated; furthermore, the clamping device cannot be affected by the existence of a central hole in the blade, so that the clamping device for fixing the indexable blade enables the blade to be clamped and located more precisely and firmer.

Description

technical field [0001] The invention relates to the blunt circle detection technology of an indexable insert, in particular to a clamping device for fixing an indexable insert. Background technique [0002] At present, there are various shapes of indexable cutting inserts made of cemented carbide or ceramic materials, such as diamond-shaped, triangular, and circular indexable inserts, and such inserts are usually fixed by mechanical clamping devices. There are many types of clamping devices for fixing indexable blades. For example, the patent No. ZL95193314.0 discloses a clamping device for fixing indexable blades. The blade with holes is clamped. When the clamping device of the clamping device clamps the blade, there is no effective limit device and moving guide device between the clamping part and the tool seat. The distance between the clamping bolt and the clamping part The friction between them will cause the clamping part to rotate left and right, which may cause the ...

There are many types of clamping devices for fixing indexable blades. For example, the patent No. ZL95193314.0 discloses a clamping device for fixing indexable blades. The blade with a hole is clamped. When the clamping device of the clamping device clamps the blade, there is no effective limit device and moving guide device between the clamping part and the tool holder. The friction between them will cause the clamping parts to rotate left and right, which may cause the blade to shift, affect the precise positioning of the blade, and then affect the instability of the entire detection system
