Key duplicating machine

Abstract

A key duplicating machine is used for duplicating notches of an original key to a key blank. The key duplicating machine includes a base assembly, a first sliding table, a first driving mechanism, a first clamp, a second clamp and a cutting module. The first sliding table is slidably mounted on the base assembly. The first driving mechanism controls a position of the first sliding table. The two clamps are fixed on the base assembly. The original key and key blank are fixed on the two clamps respectively. The cutting module is pivotally mounted on the first sliding table, and has a guiding element, a TO cutting element and a motor. Gravity makes the cutting module rotate, and makes the guiding element and the cutting element press against the keys. The duplicating can be carried out with one hand, which is easier to use and more precise.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention relates to a cutting machine tool, especially to a key duplicating machine.2. Description of the Prior Arts[0002]With reference to FIGS. 23 and 24, a conventional key duplicating machine can be used for duplicating shapes of notches on a side of a key. The key duplicating machine comprises a base assembly 91 and a swing table 92. The swing table 92 is pivotally mounted on a pivot shaft 911 of the base assembly 91 and is linearly movable along the pivot shaft 911. A first clamp 921 and a second clamp 922 are fixed on a top of the swing table 92. The base assembly 91 has a cutting element 912, a motor 913 and a guiding element 914. The motor 913 rotates the cutting element 912. A shape of a tip of the guiding element 914 is same as a shape of the edge of the cutting element 912, and a distance between the guiding element 914 and the cutting element 912 is equal to a distance between the first clamp 921 and...

AI Technical Summary

Benefits of technology

This patent is about a key duplicating machine that fixes keys on a base and has a motor, guiding element, and cutting element that move for accurate and easy duplication. The keys are first clamped on the machine and the motor, guiding element, and cutting element move to duplicate the keys. The increased weight of the cutting module reduces the impact of reaction force from key cutting and stabilizes the position of the guiding element and cutting element, improving duplication precision. The cutting depth is automatically controlled by the weight of the cutting module, making the machine easier to use and faster in duplication.

Problems solved by technology

The deviations are gradually accumulated through each duplication process, and finally cause a failed duplicated key.

Second, when duplicating a key, the user needs to control movements of the swing table 92 in two different directions simultaneously, which makes it more difficult to use.
