Examples

Laser cutters are widely used in various fields due to their excellent properties. When the laser cutter works, high-energy laser irradiates on the cut material, and the cut material is vaporized so as to complete cutting of the cut material.

In some laser headstocks, probes are used as a workpiece positioning member to detect whether a clamped workpiece is in place. Because a certain amount of soot is generated in the process of cutting by laser, the probe needs to be reset into the spindle box so as to avoid the pollution of the probe by the soot. Through holes are needed to be arranged on the spindle box corresponding to the extending positions of the probes so as to ensure that the probes can normally enter and exit.

After the through hole is formed in the spindle box, soot possibly enters the spindle box along the through hole, and devices such as a laser receiver and the like are possibly damaged under the influence of the soot, so that the laser spindle box is disclosed in the application.

Specifically, referring to fig. 1, the laser headstock provided by the present utility model includes a housing 10, the housing 10 is a housing of the headstock, and a laser receiver is disposed in the housing 10. The laser head 20 is installed to the below of casing 10, and laser head 20 is connected with laser receiver, and laser that laser receiver produced is transmitted to waiting to process the work piece through laser head 20, and then cuts the work piece. A probe 30 is also provided in the housing 10, the probe 30 being used to detect whether a workpiece is clamped in place. The first linear driver 40 for driving the probe 30 to move is also arranged in the machine shell 10, and the probe 30 is driven to move up and down by the first linear driver 40, so that the probe 30 is prevented from interfering with a workpiece in the workpiece processing process. The probe 30 is required to move up and down, and a through hole is provided in the housing 10 at a position corresponding to the up and down movement of the probe 30, and the probe 30 moves up and down through the through hole by the driving of the first linear actuator 40.

In order to prevent soot generated during the processing from entering the housing 10 and contaminating the laser receiver, a dust cover 50 and a second linear actuator 60 are also provided in the housing 10. The second linear actuator 60 is used for driving the dust cover 50 to close the through hole.

More specifically, when the workpiece clamping is completed, the second linear driver 60 drives the dust cover plate 50 to move, so that the dust cover plate 50 no longer closes the through hole. The first linear driver 40 drives the probe 30 to move downwards, the probe 30 passes through the through hole downwards from the inner cavity of the casing 10 and then is abutted to the workpiece, after the probe 30 is detected, the first driving structure drives the probe 30 to move upwards, the probe 30 returns to the initial position, and at the moment, the second linear driver 60 drives the dustproof cover plate 50 to move, so that the dustproof cover plate 50 seals the through hole, and soot is prevented from entering the casing 10. The laser head 20 emits laser light to process the workpiece.

Specifically, the first linear actuator 40 may be one of a cylinder, a linear motor, or a screw structure.

Further, an electromagnetic switch is arranged in the sliding table cylinder, and after the probe body is lifted and reset, the electromagnetic switch is triggered, so that the through hole is closed after the probe 30 completely enters the casing 10, and the probe 30 is prevented from being impacted by the dust cover 50 in the process of closing the through hole.

To further ensure that the probe 30 does not strike the dust cap 50 during operation, the laser headstock also includes a travel switch 70 and a controller. The travel switch 70 is similarly disposed in the housing 10, and the controller is electrically connected to the first linear actuator 40 and the travel switch 70, respectively.

Specifically, with reference to fig. 2 or 3, after the travel switch 70 is set, when the second linear driver 60 drives the dust cover plate 50 to be not closed (far away from the through hole), the travel switch 70 is triggered when the dust cover plate 50 moves to the travel end of the second linear driver 60, at this time, the travel switch 70 transmits a signal to the controller, and the controller controls the first linear driver 40 to drive the probe 30 to move downwards, so that the probe 30 is prevented from striking the dust cover plate 50 in case that the second linear driver 60 fails to drive the dust cover plate 50 to be not closed. After the test of the probe 30 is completed, the probe 30 is reset to trigger the electromagnetic switch, so that the controller controls the second linear driver 60 to drive the dustproof cover plate 50 to close the through hole, and the ash in the machine shell 10 can not enter.

Specifically, the contact surface between the dust cover plate 50 and the casing 10 is closely fitted so that soot can be completely isolated.

Optionally, a thin silica gel or a thin sealing layer may be disposed on the contact surface between the dust cover 50 and the casing 10, so as to further isolate the soot from the inner cavity of the casing 10.

Still further, the laser headstock further includes a photo sensor mounted in the machine case 10 and facing the through hole (not shown) for detecting whether the dust cover 50 closes the through hole. The photoelectric sensor is electrically connected with the controller, when the travel switch 70 fails, namely, the dustproof cover plate 50 is still in a closed state, and the travel switch 70 sends a signal to the controller, the photoelectric sensor still detects that the dustproof cover plate 50 closes the through hole, the photoelectric sensor feeds back the signal to the controller, the controller compares the signals of the photoelectric sensor and the travel switch 70, the controller can make correct judgment, and thus, the controller does not control the first linear driver 40 to drive the probe 30 to fall, and the probe 30 can be effectively prevented from being damaged due to collision with the dustproof cover plate 50.

Preferably, in an embodiment of the present utility model, the laser headstock further includes an adapter plate 90, the adapter plate 90 is mounted on the slip table, and the probe 30 is mounted on the adapter plate 90. The adapter plate 90 is an L-shaped adapter plate 90, a vertical portion 91 of the adapter plate 90 is fixedly connected with the sliding table, and a horizontal portion 92 of the adapter plate 90 is used for installing the probe 30. The horizontal portion 92 of the adapter plate 90 extends to enable the probe 30 to be spaced from the sliding table by a certain distance, so that interference of the probe 30 by the sliding table during working is avoided.

Referring to fig. 2 or 3, the dust cover 50 is fixedly connected to an output end of the second linear actuator 60. Specifically, the second linear driver 60 is fixedly connected to the inner wall of the casing 10 through a mounting plate, and the second linear driver 60 is usually a cylinder, so that the baffle plate can be driven to move at a relatively high speed.

Preferably, the dust cover 50 is generally a thin plate, so that it is simpler for the second linear actuator 60 to actuate the dust cover 50.
