Description

Technical Field

[0001] This utility model belongs to the field of laser cutting devices, specifically, it relates to a planar laser cutting device. Background Technology

[0002] In laser cutting machine tool control, the distance between the laser cutting head and the workpiece surface often changes due to the undulation of the workpiece surface or the deformation of the workpiece.

[0003] Chinese Patent No. CN218135769U discloses a planar laser cutting device. By setting up a pressure block, a clamping spring, a rotating sleeve, and a locking block, when the guide rod moves down with the protective sleeve, the guide rod can drive the pressure block to move down as well, and the pressure block continuously compresses the clamping spring. When the protective sleeve slides to the position where it completely covers and protects the end of the laser cutting head, the rotating sleeve is then turned so that the locking block slides into the inner side of the locking groove when the rotating sleeve rotates. In this way, the locking block can counteract the rebound force of the clamping spring on the guide rod and maintain the stability of the protective sleeve at the end of the laser cutting head.

[0004] However, in the aforementioned planar laser cutting device, the position of the protective sleeve is positioned by locking the locking block into the locking groove. Although the protective sleeve can protect the laser cutting head, the distance between the bottom end of the protective sleeve and the bottom end of the laser cutting head is fixed, which makes it inconvenient to adjust the distance between the laser cutting head and the workpiece, and affects the precise adjustment of the distance between the laser cutting head and the workpiece.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a planar laser cutting device.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] A planar laser cutting device includes an operating table, a support plate slidably fitted on the top of the operating table, a mounting plate slidably fitted on one side of the support plate, a limiting handle bolt for positioning the mounting plate threaded on one side of the support plate, a laser cutting head embedded at the bottom of the mounting plate, a first limiting ring elastically slidably fitted below the mounting plate, two guide rods connected to the first limiting ring, two scale rods provided on the upper side of the mounting plate, a top plate fixed on the two scale rods, a pressure plate slidably fitted on the two scale rods, and an adjusting handle screw threaded on the upper side of the top plate.

[0009] Optionally, the upper end of the guide rod is provided with an outward flange, and a spring is provided between the outward flange and the mounting plate and sleeved on the guide rod.

[0010] Optionally, a sliding barrel corresponding to the guide rod is provided on the upper side of the first limiting ring. The sliding barrel is elastically slidably sleeved on the guide rod. A tension spring is provided between the guide rod and the bottom surface of the inner wall of the sliding barrel. A positioning handle screw is threadedly fitted on the side of the sliding barrel. A second limiting ring is fixedly sleeved on the bottom end of the guide rod. A third limiting ring is provided at the opening of the sliding barrel. The third limiting ring is located above the second limiting ring and is slidably sleeved on the guide rod. A through hole corresponding to the positioning handle screw is provided on the side of the third limiting ring.

[0011] Optionally, the mounting plate is provided with a first guide hole corresponding to the guide rod, the guide rod is slidably fitted in the first guide hole, a T-shaped channel is provided on one side of the support plate, and a T-shaped guide strip is provided on one side of the mounting plate, the T-shaped guide strip is slidably fitted in the T-shaped channel.

[0012] Optionally, two first linear motors are embedded on the upper side of the operating platform. The movable end of the first linear motor is provided with a support bar, and a second linear motor is provided on the two support bars. The support plate is fixed to one side of the second linear motor.

[0013] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0014] By placing the workpiece on the operating table, rotating the adjusting handle screw pushes the pressure plate to slide on the two scale rods. The pressure plate pushes the guide rod and the first limiting ring to slide, adjusting the distance between the bottom end of the first limiting ring and the bottom end of the laser cutting head. By setting the scale rod, it is easy to improve the accuracy of adjusting the distance between the bottom end of the first limiting ring and the bottom end of the laser cutting head. Rotating the limiting handle bolt releases the limitation of the mounting plate, allowing the mounting plate to slide down on the support plate, so that the first limiting ring is in contact with the upper side of the workpiece. Then, the position of the mounting plate is positioned by the limiting handle bolt. Rotating the adjusting handle screw in the opposite direction moves the first limiting ring up, facilitating the movement of the laser cutting head.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] Please see Figure 1-4 As shown, this embodiment provides a planar laser cutting device, including an operating table 1, a support plate 2 slidably fitted on the top of the operating table 1, an mounting plate 3 slidably fitted on one side of the support plate 2, a limiting handle bolt 4 for positioning the mounting plate 3 threadedly fitted on one side of the support plate 2, a laser cutting head 5 embedded at the bottom of the mounting plate 3, a first limiting ring 6 elastically slidably fitted below the mounting plate 3, two guide rods 7 connected to the first limiting ring 6, two scale rods 8 provided on the upper side of the mounting plate 3, a top plate 9 fixed on the two scale rods 8, a pressure plate 10 slidably fitted on the two scale rods 8, and an adjusting handle screw 11 threadedly fitted on the upper side of the top plate 9.

[0026] By placing the workpiece on the operating table 1, rotating the adjusting handle screw 11 pushes the pressure plate 10 to slide on the two scale rods 8. The pressure plate 10 pushes the guide rod 7 and the first limiting ring 6 to slide, adjusting the distance between the bottom end of the first limiting ring 6 and the bottom end of the laser cutting head 5. By setting the scale rods 8, it is easy to improve the accuracy of adjusting the distance between the bottom end of the first limiting ring 6 and the bottom end of the laser cutting head 5. Rotating the limiting handle bolt 4 releases the limitation of the mounting plate 3, allowing the mounting plate 3 to slide down on the support plate 2, so that the first limiting ring 6 is in contact with the upper side of the workpiece. Then, the position of the mounting plate 3 is positioned by the limiting handle bolt 4. Rotating the adjusting handle screw 11 in the opposite direction moves the first limiting ring 6 up, facilitating the movement of the laser cutting head 5.

[0027] Please see Figure 3 As shown, the upper end of the guide rod 7 in this embodiment is provided with an outward flange, and a spring 12 is provided between the outward flange and the mounting plate 3, which is sleeved on the guide rod 7 so that the spring 12 can elastically support the guide rod 7 and the pressure plate 10 through the outward flange.

[0028] Please see Figure 2-3 As shown, in this embodiment, a sliding barrel 13 corresponding to the guide rod 7 is provided on the upper side of the first limiting ring 6. The sliding barrel 13 is elastically slidably sleeved on the guide rod 7. A tension spring 14 is provided between the guide rod 7 and the bottom surface of the inner wall of the sliding barrel 13. A positioning handle screw 15 is threadedly fitted on the side of the sliding barrel 13. A second limiting ring 16 is fixedly sleeved on the bottom end of the guide rod 7. A third limiting ring 17 is provided at the opening of the sliding barrel 13. The third limiting ring 17 is located above the second limiting ring 16 and is slidably sleeved on the guide rod 7. A through hole corresponding to the positioning handle screw 15 is provided on the side of the third limiting ring 17, so as to restrict the sliding position of the sliding barrel 13 through the third limiting ring 17 and keep the initial positioning position of the sliding barrel 13 the same as that of the positioning handle screw 15.

[0029] Please see Figure 2-3 As shown, the mounting plate 3 in this embodiment is provided with a first guide hole corresponding to the guide rod 7. The guide rod 7 is slidably fitted in the first guide hole. A T-shaped channel 201 is provided on one side of the support plate 2, and a T-shaped guide strip 301 is provided on one side of the mounting plate 3. The T-shaped guide strip 301 is slidably fitted in the T-shaped channel 201, which facilitates the sliding of the T-shaped guide strip 301 through the T-shaped channel 201, thereby improving the sliding stability of the mounting plate 3. The T-shaped guide strip 301 is positioned by the limiting handle bolt 4, thereby positioning the mounting plate 3.

[0030] Please see Figure 1 As shown, in this embodiment, two first linear motors 101 are embedded on the upper side of the operating table 1. The movable end of the first linear motor 101 is provided with a support bar 102. A second linear motor 103 is provided on the two support bars 102. The support plate 2 is fixed to one side of the second linear motor 103, so that the first linear motor 101 can drive the laser cutting head 5 to move along the length direction of the operating table 1, and the second linear motor 103 can drive the laser cutting head 5 to move along the width direction of the operating table 1.

[0031] Working principle: Place the workpiece on the operating table 1, then rotate the adjusting handle screw 11 to push the pressure plate 10 to slide on the two scale rods 8. The pressure plate 10 pushes the guide rod 7 and the first limiting ring 6 to slide, adjusting the distance between the bottom end of the first limiting ring 6 and the bottom end of the laser cutting head 5. By setting the scale rods 8, it is easy to improve the accuracy of adjusting the distance between the bottom end of the first limiting ring 6 and the bottom end of the laser cutting head 5. Rotate the limiting handle bolt 4 to release the limitation of the mounting plate 3, so that the mounting plate 3 slides down on the support plate 2, so that the first limiting ring 6 is in contact with the upper side of the workpiece. Then, the position of the mounting plate 3 is positioned by the limiting handle bolt 4. Rotate the positioning handle screw 15, and the tension spring 14 pulls the sliding barrel 13 to move the first limiting ring 6 up, which facilitates the movement of the laser cutting head 5.
