Abstract

The utility model discloses a lock cylinder groove broacher for lock making. The structure of the lock cylinder groove broacher is as follows: the lock cylinder groove broacher comprises a lathe bed (1), a carriage (3) and two knife bridges (4), wherein the carriage is sheathed above the lathe bed in a sliding way, two knife bridges (4) are arranged on the lathe bed (1) in parallel, and two knife boxes (5) are arranged on each knife bridge, a reinforcing rib plate (6) is arranged in the middle of the lathe body, and the rib plate supports and props against the lower part of each knife bridge, and a guide rail pair (2) is arranged between the carriage and the lathe body. In the novel lock cylinder groove broacher, four lock cylinders can be processed at the meantime when the carriage slides in a reciprocating way, the working efficiency is greatly improved, the stability of the lathe body structure is enhanced, the deformation and vibration are reduced in the cutting process of the knife bridges, the machine wear of the lathe bed is avoided, and the processing precision of the lock cylinder is improved and kept.

Description

Lock core slot-producing machine

Technical field

The utility model relates to the lockmaking process equipment, relates in particular to a kind of lock core slot-producing machine that lock core is carried out machining.

Background technology

The equipment of making the lock core alveolus is groove broacher, and its structure generally comprises frame lathe bed, planker, clamp mechanism, cutting mechanism composition, and its middle carriage slip cap is contained on the lathe bed, and clamp mechanism is arranged on the planker, and cutting mechanism is installed on the lathe bed; Wherein cutting mechanism comprises cutter bridge, cutter box and broaching tool.With the lock core embryo spare to be processed clamp mechanism and fixing of packing into, by planker reciprocatingly sliding on lathe bed, broaching tool carries out machining to lock core embryo spare.

The lock core slot-producing machine of prior art, generally as shown in Figure 1, cutter bridge 4 is fixing and supporting by the end plate 8 at lathe bed 1 two ends, and its cutter bridge 4 is one, and cutter box 5 is two pairs, is divided into cutter bridge the right and left, can only process two embryo spares at most at every turn like this, and operating efficiency is low.

Summary of the invention

The utility model purpose is to provide a kind of increasing work efficiency, simultaneously the durable lock core slot-producing machine of sound construction.

A kind of lock core slot-producing machine of the present utility model, its structure comprises lathe bed, planker, cutter bridge, its middle carriage slip cap is contained in the lathe bed top, the cutter bridge is fixed and is supported by the end plate at lathe bed two ends, it is characterized in that: described cutter bridge is two, parallel being installed in side by side on the lathe bed, installing two secondary cutter boxes on each cutter bridge.

For increasing the structural strength of lock core slot-producing machine, improve the stability of working angles, also be provided with deep floor in the middle of the lathe bed, this floor supporting also presses on cutter bridge below.

For avoiding the fricative wear and tear in machines of lathe bed and planker, install guideway between described planker and the lathe bed, this guideway comprises the guide rail that is inlaid in lathe bed top, the slide block of planker lower end installing.

Lock core slot-producing machine of the present utility model, owing to be equiped with two cutter bridges, fourth officer cutter box when planker is reciprocatingly slided, can be processed four lock cores simultaneously, has improved operating efficiency greatly; Cutter bridge below sets firmly the supporting floor, has reduced distortion and vibration that the cutter bridge produces at working angles, increases lathe bed structure stability, has improved the lock core machining accuracy; Install guideway between lathe bed and the planker, avoided the wear and tear in machines of lathe bed,, can reduce cost of upkeep, and can improve and keep the machining accuracy of lock core by maintenance or replacing guideway.
