Abstract

The utility model discloses an improved typing code machine made of metallic material. The utility is characterized in that the column shaped boss in the tail section of every steel code is evenly cut to be single a side with equal width, and the periphery of the locating disk assembled to match with the single side is made to be an equilateral polygon, so that the steel code and the locating disk have simple process and precise and reliable matching and installation. In addition, a buffer block and a compression spring with impact holes are arranged on the rotary table bracket in the connecting place of the rotary table bracket and a gun block. The impact hole and the firing pin are homocentric, and the buffer block pushes the steel code to move a certain distance to the left under the action of the compression spring in normal state. The firing pin can not strike the steel code when the printer strikes nothing, and the huge impact force to the return spring of the steel code is avoided to prolong the service life.

Description

The grade of steel automatic stamper

Technical field

The utility model is a kind of improved metal material typewriting ink recorder tool.

Background technology

The location of the letter punch of existing character code printer adopts the square afterbody of character code and the square opening of positioning disk to cooperate the location, processed complex, quality of fit is difficult for guaranteeing, result of use is relatively poor, and in addition, the back-moving spring of letter punch hits under the situation at the printer sky, still be subjected to striker huge impact power, not only make the material of back-moving spring require height, it is big that diameter becomes, and reduced service life.

Summary of the invention

The purpose of this utility model is a kind of improved grade of steel automatic stamper of design, and not only the location of letter punch processing is simple, accurately convenient, and the back-moving spring of the letter punch power that is not hit when sky hits, and back-moving spring is reliability and durability, long service life.

The purpose of this utility model is achieved like this: a kind of grade of steel automatic stamper of being made up of rifle body, cylinder sleeve, striker, air valve, switch, air flue, character code rotating disk, support for rotary disc, letter punch, back-moving spring etc., the periphery that it is characterized in that positioning disk cuts into equilateral polygon, the afterbody cylindrical boss cutting of corresponding equipped letter punch goes out wide monolateral, the localization part of letter punch not only is easy to processing and accurate positioning like this; In addition, be positioned at the junction of support for rotary disc and rifle body, the buffer stopper of mounting strap impingement holes and compression spring on support for rotary disc, the center of this impingement holes and striker centres, under the normality, buffer stopper pushes the letter punch certain distance that moves to left under the effect of stage clip, when the printer sky hits, striker bump is less than letter punch, makes the back-moving spring of letter punch avoid huge impact power and increase the service life.

The utility model carry the grade of steel automatic stamper rational in infrastructure, processing simple, easy for installation, safe and reliable.

Description of drawings

Fig. 1 is the main cross-sectional schematic that the utility model is carried the grade of steel automatic stamper.

Fig. 2 is an A-A cross-sectional schematic among Fig. 1.

Fig. 3 is a B-B cross-sectional schematic among Fig. 1.

The specific embodiment

From Fig. 1, Fig. 2, among Fig. 3 as can be seen: a kind of by support for rotary disc 1, alignment pin 2, locating pin spring 3, axle sleeve 4, character code rotating disk 5, positioning disk 6, letter punch 8, cylinder sleeve 12, end cap 13, cover plate 14, air valve 18, striker 19, rifle body 21, switch 24, plate machine 25, centre bolt 26, bumper ring 27, the grade of steel automatic stamper that 17 grades are formed, the equal cutting of afterbody cylindrical boss that it is characterized in that being installed in several letter punches 8 in the character code rotating disk 5 goes out wide monolateral, and correspondingly make several equilateral polygons with the periphery of the equipped mutually positioning disk 6 of letter punch 8, such letter punch 8 and positioning disk 6 are easy to make, and the location cooperates accurately reliable; In addition, be positioned at the junction of support for rotary disc 1 and rifle body 21, on support for rotary disc 1, use the mobilizable buffer stopper 9 and the compression spring 10 of bearing pin mounting strap impingement holes, the centres of the center of the impingement holes on the buffer stopper 9 and striker 19, there is a round boss at the impingement holes place of the left surface of buffer stopper, under the normality, buffer stopper 9 is pushing tow letter punch 8 certain distance that moves to left under the effect of two compression springs 10, when grade of steel automatic stamper sky is beaten, striker 19 bump is less than letter punch 8, makes the back-moving spring 7 of letter punch 8 avoid huge impact power and increase the service life; When printing grade of steel, the operator must alignment pieces by tight letter punch 8, buffer stopper 9 overcomes compression spring 10 and moves to right and reset, and pulls plate machine 25, striker 19 just can strike letter punch 8, just can print the marking clearly; This grade of steel is printed and is adopted compressed air, the hollow cavity of the handle portion of rifle body 21 is a main gas tank 20, the breather pipe 23 that hollow is set in the hollow cavity is connected the right side air chamber of main gas tank 20 and air valve 18, compressed air in the main gas tank 20 is supplied with by interface 22 external air compressor machines, when plate machine 25 is not worked, switch 24 is failure to actuate, when compressed air is full of main gas tank 20, also be full of the right side air chamber of air valve 18, air pressure balance makes air valve 18 static relatively, only depends on the effect of spring 16 to compress and be sealed in the right output port of cylinder sleeve 12; When hand is pulled plate machine 25, make switch 24 actions and close the following hole of breather pipe 23, air with pressure in the main gas tank 20 promote sealing ring 15 when backing down air valve 18 to the right and close steam vent, and a large amount of compressed air moment enters and promotes the plunger type striker 19 bump letter punch 8 that moves to left in the cylinder sleeve in air valve 18 left sides and finish print job; Grade of steel is printed and is finished, unclamp finger, plate machine 25 and switch 24 reset, air valve 18 is in relative static conditions again and is pressed on the right output port of cylinder sleeve 12, at this moment, take left side that the air with pressure part in striker 19 right side cylinder sleeves enters striker 19 by the steam vent 11 of cylinder sleeve 12 left side section in and promote striker 19 and move to right and reset and excessive discharge, a part is from air valve 18 excessive discharges; Repeat to pull plate machine 25 and just can finish each grade of steel printing; The character code rotating disk 5 of several letter punches 8 and positioning disk 6 are installed all can twist and be positioned on the support for rotary disc 1 by alignment pin 2, locating pin spring 3 around centre bolt 26 usefulness hands, when needs are beaten towards any one numeral, only with hand is twisted character code rotating disk 5, letter punch 8 corresponding on the character code rotating disk 5 is gone to the top, alignment pieces, pull plate machine 25 gently, print job is finished in striker 19 actions.
