Description

Technical Field

[0001] This utility model relates to the relevant technical field, specifically a laser cutting machine head clamping device. Background Technology

[0002] Profiles and tubes come in various shapes, such as rectangular, circular, or irregular shapes, and also have different diameters. Existing clamping devices, such as CN210649659U, disclose a tube support device that clamps the tube through a vertically lifting lower V-shaped support and a vertically lifting upper horizontal arm. If this structure is used in a rotary cutting head, the contact between the upper horizontal arm and the profile or tube is limited, especially for irregularly shaped tubes. During the rotary cutting process, the tube is prone to wobbling, affecting the cutting accuracy. Utility Model Content

[0003] To address the aforementioned shortcomings, this utility model provides the following technical solution:

[0005] Furthermore, the lower clamping plate has the same structure as the upper clamping plate. The bottom of the lower clamping plate is a Y-shaped plate, the bottom of the Y-shaped structure is a vertical support plate, and the upper two sides of the Y-shaped structure of the lower clamping plate are inclined support arms.

[0006] Furthermore, the mounting plate is provided with lower clamping plates at both the front and rear of the inverted L-shaped top, and fixing plates are provided on both sides of the inverted L-shaped top to fix the vertical support plates of the front and rear lower clamping plates on both sides. Reinforcing ribs are provided at both L-shaped bends of the mounting plate.

[0007] Furthermore, each of the inclined support arms has a groove, and each groove is equipped with a roller.

[0008] Furthermore, the rear side of the vertical support plate of the upper clamping plate is provided with a slider corresponding to the third double track.

[0009] Furthermore, a mounting bracket is provided on the support plate on the outer side of the tail end of the second double guide rail.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Combination Figures 1 to 3 Shown:

[0019] A laser cutting machine head clamping device, characterized in that: it includes a frame 1, a support plate 2 on one side of the frame 1 for equipment installation, a feeding hole 3 on the upper part of the support plate 2 for feeding pipes and profiles, a fixing block 4 on the support plate 2 below the feeding hole 3, a hydraulic cylinder 5 on the fixing block 4, which is used for vertical lifting power through a corresponding hydraulic system, an inverted L-shaped mounting plate 6 on the top of the piston rod of the hydraulic cylinder 5, sliders on both sides of the inverted L-shaped side of the mounting plate 6, a first double guide rail 7 in the vertical direction corresponding to the slider on the support plate 2, a lower clamping plate 8 on the upper part of the inverted L-shaped mounting plate 6, lower clamping plates 8 on both the front and rear of the top of the inverted L-shaped mounting plate 6, connecting plates 14 on both sides of the top of the inverted L-shaped mounting plate 6 to fix the vertical support plate 2 on both sides of the front and rear lower clamping plates 8, and reinforcing ribs on both sides of the L-shaped bend of the mounting plate 6 to strengthen the connection strength.

[0020] The lifting and lowering of the lower clamping plate is controlled by the first double guide rail 7 combined with the hydraulic cylinder 5. A second double guide rail 9 is provided on one side of the feed hole 3. A rectangular mounting frame 10 is provided on the second double guide rail 9. The upper frame of the rectangular mounting frame 10 extends outward to form a fixing frame 11. A third double guide rail 12 is provided laterally on the side of the fixing frame 11. An upper clamping plate 13 is provided on the third double guide rail 12.

[0021] The lower clamping plate 8 has the same structure as the upper clamping plate 13. The bottom of the lower clamping plate 8 is a Y-shaped plate, and the bottom of the Y-shaped structure is a vertical support plate. The upper sides of the Y-shaped structure of the lower clamping plate 8 are inclined support arms 15, which facilitates the support of different types of pipes or profiles.

[0022] The inclined support arm 15 has grooves, and each groove is equipped with a roller 16 to facilitate the extension and retraction of the feed.

[0023] The rear side of the vertical support plate 2 of the upper clamping plate 13 is provided with a slider corresponding to the third double track 12, which is used to control the left and right movement of the third double track. By setting the corresponding slider power, the upper clamping plate 13 can be moved left and right to adjust the clamping position.

[0024] A mounting bracket 17 is provided on the support plate 2 on the outer side of the tail end of the second double guide rail 9. An L-shaped fixing plate 18 is provided on the mounting bracket 17. The head end of the hydraulic telescopic rod 19 is fixed on the mounting bracket 17 by the fixing plate 18. The hydraulic telescopic rod 19 is arranged parallel to the second double guide rail 9. An L-shaped lifting plate 20 is provided at the top of the telescopic end of the hydraulic telescopic rod 19. One side of the lifting plate 20 is fixed to the outer side of the rectangular mounting frame 10. Reinforcing ribs are provided at the L-shaped bends on both sides of the lifting plate. The upper and lower positions of the upper clamping plate 13 can be adjusted by the extension and retraction of the hydraulic telescopic rod.

[0025] Working principle: When this clamping mechanism is working, the extension and retraction control plate of the hydraulic cylinder moves up and down on the first double guide rail via the slider. The hydraulic telescopic rod, through the lifting plate and the slider, pushes the rectangular mounting frame to move up and down on the second double guide rail, thereby driving the upper clamping plate on the fixed frame to move up and down. The movement of the slider on the third double guide rail on the fixed frame controls the left and right movement of the upper clamping plate. The above operation can automatically adjust the lateral position of the upper clamping plate to cooperate with the lower clamping plate for downward clamping according to the shape and size of the upper side of the mold or pipe. The vertical lifting and lowering of the lower clamping plate facilitates the clearance of the pipe when passing through the feed hole and the positioning after feeding, thereby better cooperating with the upper clamping plate to fit and clamp the upper side of the mold or pipe, thus realizing the clamping and positioning of molds and pipes of different shapes and diameters.
