Abstract

The utility model relates to a character code printer used for typing on a metal piece and composed of a printer seat, an assistor, a character code warehouse and a work piece holder, wherein the assistor and the work piece holder are arranged on the printer seat. The character code warehouse is composed of a digital code disc, a head character and an indexing stepping motor, wherein the character code disc is provided with a rotating shaft which is connected with an output shaft of the indexing stepping motor. The character code disc is provided with a hole, and the head character is arranged in the hole. The head character is composed of a gripping head, a spring, a stop block and a matrix. The limited block is arranged on the gripping head and is stopped on the character code disc. The spring is arranged on the gripping head and is clamped between the gripping head and the character code disc, and the matrix is fixed on the gripping head. Matrixes of digits, general letters, etc. are uniformly distributed on the character code disc by the utility model using the rotary type character code warehouse; the simple structure is convenient for quickly sorting the matrix needs printing, and the head character can be conveniently dismounted from the character code disc, thereby, the utility model is caused to conveniently replace and repair the matrix to form the movable type. Using the matrix structure which can be replaced is convenient for the selection of the range of character sizes, character fonts and characters.

Description

The character code printer

Technical field

The utility model relates to a kind of printer, relates in particular to a kind of character code printer that shows dot mark at metal.

Background technology

In existing technology, instrument, auto parts, bullet and other metal parts need the different numbering of mint-mark, job number, weighing and mark, usually adopt digital, English alphabet steel stamp, strike on metal one by one with hammer, also useful simple armstrong's patent carries out metal to be printed, because firmly uneven, the word trace is deep mixed, influence the attractive in appearance and quality of workpiece, hand labour in addition, labour intensity is big, inefficiency, even misoperation can appear.Machine typewriting depth as shallow such as existing laser typewriting, metal electrification printing machine, pneumatic stylus printer machine, be not suitable for the long preservation of complex environment mark, printing effect can not satisfy the requirement of some workpiece, need a kind of handling safety of invention reliable, typing speed is fast, is fit to the Special Automatic metal typewriting apparatus of producing in batches.

Summary of the invention

At existing technology status, the invention provides a kind of type character code printer that type matrix is changed, overhauled of being convenient to.

The utility model adopts following technical scheme:

A kind of character code printer that is used on metalwork, typewriting, by support, assistor, character code storehouse and work holder are formed, assistor and work holder are located on the support, the character code storehouse is by lettered dial, prefix and calibration stepper motor are formed, on lettered dial, be provided with rotating shaft, rotating shaft is connected with the output shaft of calibration stepper motor, on lettered dial, be provided with the hole, prefix is located in this hole, prefix is by chuck, spring, limited block and type matrix are formed, limited block be located on the chuck and stop bit in lettered dial, spring be located on the chuck and be sandwiched in chuck and lettered dial between, type matrix is fixed on the chuck.

Compared with prior art, the utlity model has following advantage:

1, this equipment adopts rotary character code storehouse, and type matrixes such as numeral, letter commonly used are distributed on the lettered dial, and is simple in structure, is convenient to the type matrix of the required printing of rapid go-on-go;

2, because the utility model can be pulled down prefix from lettered dial easily, the utility model is convenient to change, the maintenance type matrix thereby make, and forms type; Adopt replaceable type matrix structure, be convenient to the selection of font size, font, word scope, make this equipment applied range, expansion is good;

When 3, giving type matrix afterburning, hammer adopts gas-liquid power-increasing cylinder " soft putting in place " technology, guarantees that type matrix contacts with workpiece is soft, prolongs the working life of type matrix;

4, the width of nick uniformity that is printed of workpiece;

5, can set the word that to beat, automated programming by software.

The specific embodiment

A kind of character code printer that is used on metalwork, typewriting, by support 1, assistor 2, character code storehouse 3 and work holder 4 are formed, assistor 2 and work holder 4 are located on the support 1, character code storehouse 3 is by lettered dial 31, prefix 32 and calibration stepper motor 33 are formed, on lettered dial 31, be provided with rotating shaft 311, rotating shaft 311 is connected with the output shaft of calibration stepper motor 33, on lettered dial 31, be provided with the hole, prefix 32 is located in this hole, prefix 32 is by chuck 321, spring 322, limited block 323 and type matrix 324 are formed, limited block 323 be located on the chuck 321 and stop bit in lettered dial 31, spring 322 be located on the chuck 321 and be sandwiched in chuck 321 and lettered dial 31 between, type matrix 324 is fixed on the chuck 321, head at piston rod 211 is provided with pressure type matrix head 22, above-mentioned assistor 2 is a gas-liquid power-increasing cylinder 21, and gas-liquid power-increasing cylinder 21 is made up of piston rod 211 and cylinder body.

The course of work of the present utility model is as follows:

After workpiece is placed on workbench, be fixed by clamp mechanism, shake manual moving handle, workpiece is placed the typewriting position, word or the typewriting program that will beat is set on the computer of control cabinet, by control calibration stepper motor, lettered dial is determined first typewriting head automatically, gas-liquid power-increasing cylinder is beaten on workpiece by pressing the word type matrix of reinforcing on will typewriting of getting to know, gas-liquid power-increasing cylinder is removed the typewriting head, resetted by the spring head of will typewriting, workpiece moves a character-spacing by travel mechanism then, and lettered dial is determined second typewriting head automatically, afterburning again this word is touched of gas-liquid power-increasing cylinder beaten on workpiece, repeat above-mentioned action one by one until finishing all typewriting tasks of this journey according to the data that deposit computer in, set the next line distance, repeat above-mentioned typewriting action again by manual moving handle.
