Dust removal device above workbench of laser cutting machine
Technical Field
The utility model relates to a laser cutting machine technical field specifically is a dust collector of laser cutting machine workstation top.
Background
Nowadays, in the metal processing industry, laser cutting equipment is more and more important and becomes indispensable important processing equipment, and in the metal laser cutting process, because the metal is processed at an ultrahigh temperature in the processing process, a large amount of metal dust and gas are generated in the cutting process, and the gas and a large amount of fine metal dust can irreversibly harm the human body of an operator, and even can induce lung cancer, pneumoconiosis and other diseases of the operator after long-term dust inhalation. The dust suction system in laser cutting is more and more important, and the effective discharge mode aiming at the discharge of metal dust is a very important part for the dust suction system.
At present, smoke dust generated by a metal laser cutting machine mainly exists above a table board of the machine and below a laser cutting head, and the generated smoke dust can rise to a certain height when being just generated due to the fact that the laser head has a blowing function. In a dust collection system of a common laser cutting machine, the dust collection system mainly exists in a machine body, and the dust collection mode can only absorb 20-30% of all smoke dust, while neglecting a large amount of floating smoke dust generated by blowing air through a laser head, so that the dust collection effect of a common dust collection system is not obvious, and only can absorb 20-30% of the total smoke dust.
Therefore, aiming at the current situation that the existing laser cutting machine cannot effectively absorb a large amount of smoke and dust which float upwards, the problem that the research and development of the dust removing device above the worktable of the laser cutting machine is in urgent need is solved.
SUMMERY OF THE UTILITY MODEL

The adopted technical scheme is as follows: the utility model provides a dust collector of laser cutting machine workstation top, includes crossbeam, dust absorption pipe and dust catcher, the one end of dust absorption pipe with the inner chamber intercommunication of crossbeam, the other end of dust absorption pipe is connected the dust catcher, the dust absorption hole of a plurality of and crossbeam inner chamber intercommunication is seted up to the bottom of crossbeam, install on the crossbeam a plurality of with the baffle that the dust absorption hole corresponds, the baffle is right by power unit drive the dust absorption hole seals and opens. The dust suction holes are formed in the bottom of the cross beam and connected with the dust collector, so that smoke dust on the upper portion of the workbench can be sucked, and the problem that a large amount of flying smoke dust generated by blowing when the laser head cuts cannot be removed is solved; the dust suction holes and the baffles are arranged to more accurately suck the smoke dust according to the position of the laser head, namely the smoke dust collecting position, when the laser head works on the cross beam, only the dust suction holes near the laser head are opened, and the rest dust suction holes are closed, so that the wind loss of the dust collector in the cavity of the cross beam can be reduced, and the dust suction effect is more obvious.
Furthermore, a plurality of dust suction holes are arranged at intervals along the longitudinal direction of the cross beam. The device is adaptive to the moving distance (namely the working stroke) of the laser head on the beam, and does not interfere with each other, thereby being beneficial to accurately absorbing the smoke dust.
Furthermore, a sliding groove matched with the baffle is formed in one side wall of the cross beam, and the baffle is installed on the sliding groove and can slide along the sliding groove. In order to ensure that the cross section area of the dust suction hole at the bottom of the cross beam is large enough to generate a better dust suction effect, a baffle with a larger cross section area needs to be arranged correspondingly, the internal space of the cross beam is certain, so that the movable space of the baffle in the cross beam is limited, a sliding groove is formed in one side wall of the cross beam, and the external space of the cross beam is utilized to ensure that the baffle can slidably move the dust suction hole to be blocked and opened.
Furthermore, the power mechanism comprises an air cylinder, the air cylinder is fixed on the side wall of the cross beam, and a piston rod of the air cylinder is connected with the baffle. The structure of adaptation crossbeam, both ends are fixed respectively on the preceding back wall of crossbeam around the cylinder, and the piston rod can wear out the crossbeam and drive the baffle and do linear motion to can adapt to the working distance of baffle.
Furthermore, the baffle comprises a connecting part and a blocking part, the connecting part is positioned on the outer side of the cross beam, and the cross section area of the blocking part is larger than that of the dust suction hole. The connecting part is used for realizing the blocking limit of the side wall of the cross beam and matching with a gap between the blocking sliding groove and the blocking part.
Furthermore, the connecting part is perpendicular to the blocking part and protrudes upwards, and the head end of the piston rod of the cylinder is connected with the connecting part. The close fit of the plugging part and the dust absorption hole is realized.
Furthermore, the baffle is the sheet metal component of integrated into one piece, is "L" type.
Furthermore, the dust suction pipe is communicated with one of the two end parts of the cross beam through a bent pipe joint, and a sealing piece is arranged at the joint.
The utility model discloses an adopt above-mentioned technical scheme, have following advantage:
the dust suction holes are formed in the bottom of the cross beam and connected with the dust collector, so that smoke dust on the upper portion of the workbench can be sucked, and the problem that a large amount of flying smoke dust generated by blowing when the laser head cuts cannot be removed is solved; the dust suction holes and the baffles are arranged to accurately suck and remove smoke dust according to the position of the laser head, namely, a smoke dust collecting position, each dust suction hole can be independently controlled, when the laser head works on the cross beam, only the dust suction holes near the laser head are opened, and the rest dust suction holes are closed, so that the wind loss of the dust collector in the inner cavity of the cross beam can be reduced, and the dust suction effect is more obvious.
