Abstract

The utility model relates to a pneumatic impact device for stamping, which is composed of a pneumatic stamping pen, an air source of compressed air, and an air transport pipe. The utility model is characterized in that the pneumatic stamping pen is clamped on a pen frame, the pen frame is arranged on two guide rails which are mutually vertical on planes, and the pen frame is connected with screw rods of roll balls in the guide rails. A step motor is used for driving the screw rods of roll balls in the two guide rails to rotate and driving the pen frame to move freely in an X and a Y planes. The movement of the step motor is controlled by a microcomputer. Simultaneously, the pen frame is also provided with an electromagnet which can be used for driving the pneumatic pen to vertically move in a Z direction. The action of the electromagnet is also controlled by the microcomputer. When required characters are arranged in the microcomputer, the utility model can automatically stamp the characters on a label or a product according to the instructions of the microcomputer. The characters which are stamped are canonical and beautiful and can ensure accuracy.

Description

Pneumatic impacting device for stamping

The utility model relates to a kind of Pneumatic immpacting marking device, particularly guides the Pneumatic immpacting instrument to carry out the device of marking at hard material surface.

The pneumatic mark pen that existing Pneumatic immpacting marking device such as Xi'an aero-engine factory, Qianshao Fine Machinery Co., Qingdao etc. produce is made up of a body of interior dress piston and compressed air gas source and appendix.Inscribed on part or label by the hand-held pen of operator during use, the piston impact of air by compression in the pen drives nib with very high frequency target assault target, just gets character or mark at target surface.This pneumatic mark pen is owing to be artificial hand-held the inscription, and font can not guarantee standard attractive in appearance, also makes mistakes easily, and when mark on very big product of production lot such as automobile engine cylinder-body, labor strength is very big, and easier makeing mistakes.

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, and a kind of Pneumatic immpacting marking device that can automatically get the standard character according to prior setting on target is provided.

The purpose of this utility model realizes by following proposal, pneumatic mark pen clip is held on the penholder, penholder places on two orthogonal in the plane guide rails and connects with the screw of ball-screw in the guide rail, the ball-screw that drives in two guide rails with stepper motor rotates, driving penholder can move freely in the plane at X, Y, the motion of stepper motor is controlled by microcomputer, also be provided with an electromagnet on the penholder simultaneously, can drive pneumatic pen and do the vertical mobile of Z direction, the action of electromagnet is also controlled by microcomputer.

When setting out required character in microcomputer, this device can be automatically charges and attacks character on label or the product according to the instruction of microcomputer, the symbol standard of typewriting attractive in appearance, and guarantee accurately.It can be installed on the production line, gets continuous font size on product automatically, alleviates mark personnel's labour intensity greatly, improves mark quality and efficient.

Accompanying drawing is the structural representation of an embodiment of the present utility model.

Describe an embodiment of the present utility model with reference to the accompanying drawings in detail.

Among the figure, microcomputer (1) is by interface circuit (2) control two stepper motors (11) and (12) and electromagnet (5).X drives X to ball-screw (8) to stepper motor (12), and driving the penholder (9) that links with its screw can move to guide rail (7) along X.X to guide rail (7) place Y to guide rail (3) and Y on secondary guide rail (6), and link to the screw of ball-screw (4) with Y, Y plays the aiding support effect to secondary guide rail (6), it connected with X connecting for rolling between guide rail, when Y drives Y when leading screw (4) rotates to stepper motor (11), X guide rail (7) can be along Y to mobile.Like this, pneumatic pen (10) can move freely along X, Y direction under the instruction of microcomputer (1), walks out any track in the XY plane.The adhesive of electromagnet (5) is being controlled lifting and depressing of the pneumatic pen (10) that links with its moved end with unclamping, compressed air is being connected in the upper end of pneumatic pen (10), compressed air drives its nib and does the high-frequency percussion action, when pneumatic pen (10) when being depressed, just on target, lay mobile track; When pneumatic pen (10) when being lifted, can realize the conversion between stroke.

If set out required track in microcomputer, for example numeral, English character, Chinese character and brand logo are just automatically got these tracks for pneumatic on target.

Above-mentioned control procedure is realized by computer software.

The utility model is not limited to above-mentioned embodiment, can do different variations according to spirit of the present utility model.For example the ball-screw transmission can make rack-and-pinion transmission or wireline pulley transmission into.
