Technical Field

The utility model relates to a laser cutting processing technology field specifically is laser cutting auxiliary device.

Background

In laser cutting processing, a workpiece needs to be placed on a workbench of laser cutting processing equipment for cutting, and the workpiece is cut according to the required size and shape, but a cut piece finished product which is cut off is easy to tilt upwards or jump up when being separated from the workpiece, and is easy to impact a laser cutting head, so that the equipment is damaged.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a laser cutting auxiliary device.

The utility model aims at adopting the following technical scheme to realize. The basis the utility model provides a laser cutting auxiliary device, including being used for placing and supporting a plurality of locating pieces of waiting to cut the work piece, use with the locating piece cooperation and be linked together simultaneously with outside air pressure device and will wait to cut the pneumatic briquetting that the work piece compressed tightly on the locating piece at the during operation, be linked together with outside air pressure device and treat the pneumatic vibrator that the work piece produced the impact when its piston rod extension.

Preferably, a cutting allowance L exists between the workpiece to be cut and the finished product of the cutting sheet, and the distance of the cutting allowance L is 0.18mm-0.21 mm.

The utility model provides a laser cutting auxiliary device has following advantage:

1. the utility model discloses simple structure, convenient operation can prevent that cutting piece finished product striking laser cutting head, the life of extension equipment.

The foregoing description is only an overview of the technical solutions of the present invention, and in order to make the technical means of the present invention more clearly understood, the present invention can be implemented according to the content of the description, and in order to make the above and other objects, features, and advantages of the present invention more obvious and understandable, the following preferred embodiments are mentioned below, and the detailed description is given below with reference to the accompanying drawings.

Drawings

Fig. 1 is a schematic structural diagram of the laser cutting assisting apparatus according to the embodiment.

Fig. 2 is a schematic diagram of a laser cutting route in the present embodiment.

Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined purpose, the laser cutting assisting device of the present invention will be described in detail with reference to the accompanying drawings and preferred examples.

In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", and the like indicate orientations or positional relationships based on the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.

Referring to fig. 1, the laser cutting auxiliary device includes a plurality of positioning blocks 5 for placing and supporting a workpiece 2 to be cut, the number of the positioning blocks 5 can be selected according to the size and shape of the workpiece to be cut, in this embodiment, the number of the positioning blocks 5 is 4; the laser cutting auxiliary device still includes the pneumatic briquetting 4 that is linked together with outside pneumatic means simultaneously with the cooperation of locating piece 5, and the quantity of pneumatic briquetting 4 is one in this embodiment, nevertheless the utility model discloses a plurality of pneumatic briquetting also can be selected as required in other embodiments. When the pneumatic cutting machine works, the pneumatic pressing block 4 presses the workpiece 2 to be cut on the positioning block 5 under the action of an external air pressure device, so that the workpiece to be cut is prevented from shaking in the cutting process; the pneumatic pressing block 4 is provided with a pneumatic vibrator 3 communicated with an external air pressure device, when the pneumatic vibrator 3 works, a piston rod of the pneumatic vibrator 3 extends, the bottom end of the piston rod touches the top surface of the workpiece 2 to be cut and simultaneously impacts the workpiece 2 to be cut, so that a finished cutting piece product which is kept in micro-connection with the workpiece to be cut is vibrated down; wherein, the external air pressure device, the pneumatic pressing block and the pneumatic vibrator are all the prior art and are not described again.

During operation, a plurality of positioning blocks 5 are placed on the workbench, an external air pressure device and a pneumatic pressing block 4 are started, and the workpiece 2 to be cut is pressed tightly on the positioning blocks 5 by the pneumatic pressing block 4. Taking cutting of a rectangular cutting slice as an example, the cutting route is shown in fig. 2, the laser cutting head 1 is moved to a working area and is aligned with the starting point position of the workpiece 2 to be cut, the laser cutting head 1 cuts along the route shown in fig. 2, when the laser cutting head 1 cuts to the end point, a micro-link is maintained between the finished product of the cutting slice and the workpiece 2 to be cut, namely a certain cutting allowance L exists (the cutting slice is not required to be completely cut off from the workpiece to be cut during cutting), then the laser cutting head 1 is moved out of the working area, the pneumatic vibrator 3 is started, a piston rod of the pneumatic vibrator 3 starts to perform telescopic reciprocating motion and impact on the workpiece 2 to be cut, and the finished product of the cutting slice which is in micro-link with the workpiece to be cut is separated from the workpiece to be cut under the action of vibration and falls to.

According to test data in the actual operation process, the distance of the cutting allowance L of the micro-coupler, namely the laser cutting head, when the laser cutting head cuts the workpiece to be cut is about 0.18mm-0.21mm, the distance can not only ensure that the cut piece cannot bounce to damage the laser cutting head, but also ensure that a finished product of the cut piece of the micro-coupler is separated from the workpiece to be cut in the vibration process with the workpiece to be cut after cutting.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and any person skilled in the art can make any simple modification, equivalent change and modification to the above embodiments according to the technical spirit of the present invention without departing from the technical scope of the present invention.
