Blade locking unit and blade clamping fixture

Abstract

The invention discloses a blade locking unit and a blade clamping fixture. The locking unit comprises a base and a locking part assembly, wherein a first boss and a second boss are arranged at the two ends of the base, a cutter groove set is formed in the position, between the first boss and the second boss, of the base, the cutter groove set comprises a plurality of cutter grooves formed in the length direction of the base at intervals, a blade is installed in each cutter groove, and the locking part assembly comprises a pressing rod and an elastic piece; the first boss is provided with a first mounting hole, the second boss is provided with a second mounting hole, the elastic piece is arranged on the first boss and located at the side, away from the second mounting hole, of the first mounting hole, one end of the pressing rod penetrates through the first mounting hole and can push away the elastic piece, and the other end of the pressing rod is inserted into the second mounting hole. The clamping fixture comprises a plurality of locking units and a tray or a fixture base. The blade locking unit and the blade clamping fixture can effectively prevent the blades from flying out, has no thread structure and redundant pressing accessories, are simple in structure, few in parts, low in manufacturing difficulty and reliable in clamping, can clamp the multiple blades at a time, and greatly improve the production efficiency of the blades.

Description

technical field [0001] The invention relates to cutting processing, in particular to a blade locking unit and a blade clamping fixture. Background technique [0002] In the mass production of CNC blades, CNC blade products are often processed by surface treatment techniques such as grinding, polishing, sandblasting, and coating. When processing conditions permit, in order to improve the production efficiency of the product, the product will be clamped in multiple pieces. And at the same time, the conventional locking method is usually to be pressed by screws or other various locking combination accessories, and some products have some relatively harsh working conditions in the production process, such as sandblasting environment due to the existence of fine sand, which is easy to If the thread enters the thread, the thread will be blocked and the thread will fail, or the fine sand will enter the unclosed small gap formed by the cooperation of various locking combination acce...

Problems solved by technology

[0002] In the mass production of CNC blades, CNC blade products are often processed by surface treatment techniques such as grinding, polishing, sandblasting, and coating. When processing conditions permit, in order to improve the production efficiency of the product, the product will be clamped in multiple pieces. And at the same time, the conventional locking method is usually to be pressed by screws or other various locking combination accessories, and some products have some relatively harsh working conditions in the production process, such as sandblasting environment due to the existence of fine sand, which is easy to If the thread enters the thread, the thread will be blocked and the thread will fail, or the fine sand will enter the unclosed small gap formed by the cooperation of various locking combination accessories, resulting in the inability to completely remove the fine sand during subsequent cleaning, which will affect the normal processing of the subsequent process.

Another example is that the high-temperature coating environment is likely to cause the thread and elastic components to fail, which will eventually affect the continuity and production efficiency of the product production process
