Key copying machine

Abstract

The invention provides a key copying machine which is used for copying the shape of an original key to a key blank; the key copying machine comprises a base assembly, a first sliding table, a first driving structure, a first clamp, a second clamp and a cutting module; the first sliding table is movably arranged on the base assembly; the first driving structure controls the position of the first sliding table; the two clamps are arranged on the base assembly, and the original key and the key blank are fixed to the two clamps respectively; the cutting module is provided with the first sliding table in a pivoted manner and comprises a guide piece, a cutting piece and a motor, and the motor drives the cutting piece to rotate; the cutting module tends to pivot due to the gravity center positionof the cutting module, and the guide piece and the cutting piece respectively downwards press the original key and the key blank; and thus, the precision and the speed of copying the key are improvedthrough the key copying machine, operation can be conducted by a single hand, and usage is convenient.

Description

technical field [0001] The invention is a cutting tool machine, especially a key copying machine. Background technique [0002] see Figure 23 and Figure 24 As shown, the existing key duplicating machine can be used to reproduce the shape of the tooth groove on the side of the key. The main structure of the key duplicating machine includes a base assembly 91 and a rotating seat 92. The rotating seat 92 can rotate and move linearly The shaft 911 of the base assembly 91 is sheathed; the top side of the rotating seat 92 is fixed with a first clamp 921 and a second clamp 922, and the base assembly 91 has a cutting part 912, a motor 913 and a guide 914, the motor 913 drives the cutting piece 912 to rotate at a high speed, the tip shape of the guide piece 914 is the same as the peripheral shape of the cutting piece 912, and the distance between the guide piece 914 and the cutting piece 912 is the same as the distance between the first clamp 921 and the second clamp 922 The dist...

Problems solved by technology

[0006] First, the key is fixed on the swivel seat 92, but the swivel seat 92 is not fixed but rotatable and movable, so the reaction force during cutting will affect the position of the key, which will result in the depth or position of the engraved tooth groove There is an error; this error will accumulate gradually during the key copying process, and eventually the copied key cannot be used due to the accumulated error; for example, the user uses the original key to copy A key, and then uses A key to copy B key, the second key may be unusable due to the accumulation of two errors

[0007] Second, when d
