Description

Technical Field

[0001] This utility model relates to a simple auxiliary clamping device for profile sawing, belonging to the technical field of profile sawing equipment. Background Technology

[0002] Profiles are commonly used in building structures. They are objects with specific geometric shapes made from materials with certain strength and toughness through processes such as rolling, extrusion, and casting. During profile processing, sawing is necessary. When sawing to obtain long profiles, one end inevitably extends beyond the sawing device. In this case, manual or other auxiliary clamping mechanisms are required to hold and fix the end of the profile, preventing it from shaking during sawing and thus avoiding interference with the normal sawing process.

[0003] However, manual fixing results in high labor costs, and existing auxiliary clamping mechanisms are not only complex in structure and expensive to assemble, but also prone to damaging the profiles when clamping them.

[0004] Therefore, the research objective of this utility model is to provide a simple auxiliary clamping device for profile sawing. Utility Model Content

[0005] To address the shortcomings of the aforementioned technologies, this utility model provides a simple auxiliary clamping device for profile sawing. The upper and lower clamping plates, driven by cylinders, clamp and fix the ends of the profiles. The upper clamping plate is equipped with an anti-collision bar to prevent the profiles from being damaged when the upper clamping plate descends.

[0006] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows:

[0007] A simple auxiliary clamping device for profile sawing includes a frame, a lower clamping plate, an upper clamping plate, and a crash bar. The two ends of the lower clamping plate are movably mounted on the frame via guide rods, and the bottom of the lower clamping plate is connected to a first cylinder that drives its lifting and lowering. The upper clamping plate is located directly above the lower clamping plate, with a connecting plate fixed to one end and a lifting plate fixed to the other end of the connecting plate. The lifting plate is movably mounted on the frame via a slide rail slider, and its bottom is connected to a second cylinder that drives its lifting and lowering. The crash bar is movably mounted on the lifting plate, and a locking nut is threaded onto the crash bar.

[0008] Furthermore, the upper clamping plate, connecting plate, and lifting plate are fixedly connected in a Z-shaped structure, wherein connecting reinforcing ribs are provided between the upper clamping plate and the connecting plate, and between the connecting plate and the lifting plate.

[0009] Furthermore, a first mounting plate is fixedly connected to the back of the lifting plate, the anti-collision bar is movably mounted on the first mounting plate, two sets of locking nuts are provided and respectively abut against the top and bottom of the first mounting plate; the top end of the piston rod of the second cylinder is fixedly connected to the first mounting plate.

[0010] Furthermore, a supporting square tube is horizontally fixed at the front end of the frame, and the guide rods at both ends of the lower clamping plate are vertically mounted on the supporting square tube via linear bearings. The first cylinder is fixed on the supporting square tube by bolts.

[0011] Furthermore, a gantry bracket is provided vertically upward at the rear end of the frame, and a second mounting plate is horizontally fixed at the bottom of the inner side of the gantry bracket. The rear end of the second mounting plate extends to provide an extension that cooperates with the anti-collision bar, and the extension is located directly below the anti-collision bar.

[0012] Furthermore, the second cylinder is fixed to the second mounting plate by bolts.

[0013] Furthermore, the bottom of the upper clamping plate is integrally provided with a toothed structure along its length.

[0014] The beneficial effects of this utility model are: 1.

Detailed Implementation

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the following description is provided in conjunction with the appendix. Figure 1-6 Further analysis of this utility model is then conducted.

[0023] like Figure 1-6 As shown, a simple auxiliary clamping device for profile sawing includes a frame 1, a lower clamping plate 2, an upper clamping plate 3, and a crash bar 4. The two ends of the lower clamping plate 2 are movably mounted on the frame 1 via guide rods 5, and the bottom of the middle end is connected to a first cylinder 6 that drives its lifting and lowering. The upper clamping plate 3 is located directly above the lower clamping plate 2, and one end of it is fixedly connected to a connecting plate 7. The other end of the connecting plate 7 is fixedly connected to a lifting plate 8. The lifting plate 8 is movably mounted on the frame 1 via a slide rail slider 9, and its bottom is connected to a second cylinder 10 that drives its lifting and lowering. The crash bar 4 is movably mounted on the lifting plate 8, and a locking nut 11 is threaded onto the crash bar 4.

[0024] In this embodiment, preferably, the upper clamping plate 3, the connecting plate 7 and the lifting plate 8 are fixedly connected in a Z-shaped structure, wherein connecting reinforcing ribs are provided between the upper clamping plate 3 and the connecting plate 7, and between the connecting plate 7 and the lifting plate 8.

[0025] In this embodiment, preferably, a first mounting plate 12 is fixedly connected to the back of the lifting plate 8, and the anti-collision bar 4 is movably mounted on the first mounting plate 12. Two sets of locking nuts 11 are provided and respectively abut against the top and bottom of the first mounting plate 12. The height position of the anti-collision bar 4 on the first mounting plate 12 is adjusted according to the thickness of the profile so that the length of the anti-collision bar 4 below the first mounting plate 12 is equal to the thickness of the profile, and the anti-collision bar is locked and fixed by the locking nuts 11. The top end of the piston rod of the second cylinder 10 is fixedly connected to the first mounting plate 12. When the second cylinder 10 drives the lifting plate 8 to descend, causing the upper clamping plate 3 to descend to clamp and fix the profile, due to the limiting effect of the anti-collision bar 4, the upper clamping plate 3 can only descend to a height consistent with the thickness of the profile, thereby avoiding the upper clamping plate 3 from descending too far and damaging the profile.

[0026] In this embodiment, preferably, a supporting square tube 13 is horizontally fixed at the front end of the frame 1, and the guide rods 5 at both ends of the lower clamping plate 2 are vertically mounted on the supporting square tube 13 via linear bearings, and the first cylinder 6 is fixed on the supporting square tube 13 by bolts.

[0027] In this embodiment, preferably, a gantry bracket 14 is provided vertically upward at the rear end of the frame 1, and a second mounting plate 15 is horizontally fixed at the bottom of the inner side of the gantry bracket 14. The rear end of the second mounting plate 15 extends to provide an extension 15a that cooperates with the anti-collision bar 4. The extension 15a is located directly below the anti-collision bar 4. When the bottom end of the anti-collision bar 4 contacts the extension 15a, it indicates that the upper clamping plate 3 has been lowered into place to clamp and fix the profile.

[0028] In this embodiment, preferably, the second cylinder 10 is fixed to the second mounting plate 15 by bolts.

[0029] In this embodiment, preferably, the bottom of the upper clamping plate 3 is integrally provided with a toothed structure 3a along its length direction. The toothed structure 3a can increase the friction between the upper clamping plate 3 and the profile, so that the upper clamping plate 3 can clamp and fix the profile more stably.

[0030] In use, this invention works as follows: Based on the height of the sawing mechanism or profile, the height of the lower clamping plate 2 is adjusted using the first cylinder 6 to match the height of the profile. The end of the profile is then placed on the lower clamping plate 2. The upper clamping plate 3 is then lowered using the second cylinder 10 to clamp and fix the end of the profile, preventing it from wobbling during sawing and ensuring normal sawing operations. The height of the anti-collision rod 4 is adjusted on the first mounting plate 12 according to the thickness of the profile, ensuring that the length of the anti-collision rod 4 below the first mounting plate 12 is equal to the thickness of the profile. The anti-collision rod is then locked in place using the locking nut 11. When the second cylinder 10 drives the lifting plate 8 to descend, causing the upper clamping plate 3 to descend and clamp the profile, the limiting effect of the anti-collision rod 4 prevents the upper clamping plate 3 from descending excessively and damaging the profile.
