Abstract
Description
Technical Field
[0001] This utility model relates to the field of sheet tensioning technology, specifically a sheet clamping and tensioning mechanism for a laser cutting machine. Background Technology
[0002] The sheet clamping and tightening mechanism of a laser cutting machine is a device used to clamp and tighten the sheet material to be cut on a laser cutting machine.
[0003] Based on the above, the inventors have discovered that: Currently, there are many sheet clamping and tightening mechanisms for laser cutting machines on the market. However, in general, the sheet clamping and tightening mechanisms of laser cutting machines require the operator to directly place the sheet on the processing table of the laser cutting machine for clamping. When clamping sheets of different lengths, the operator needs to change different clamping devices to limit their movement, which can easily cause the clamped sheet to loosen, thus affecting the normal clamping and tightening of the sheet. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a sheet clamping and tightening mechanism for laser cutting machines, aiming to achieve a more practical purpose. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0005] This utility model discloses a sheet clamping and tightening mechanism for a laser cutting machine, including a base, two concave plates sliding on the top of the base, a limiting mechanism on the outer wall of the two concave plates, and an adjustment mechanism on the outer wall of the base.
[0006] The limiting mechanism includes:
[0007] Two clamping plates, the outer walls of which slide against the outer surface of the concave plate. Two concave plates are fixed with perforated plates on both sides. The inner walls of the four perforated plates are threaded with screws. The tops of the four screws are fixed with support plates. The tops of the four support plates are located at the bottom of the clamping plates.
[0008] As a preferred embodiment of this utility model, both sides of the two concave plates are provided with sliding grooves, the inner walls of the four sliding grooves are provided with protrusions, and one side of each of the four protrusions is fixed to the outer wall of the clamping plate.
[0009] As a preferred embodiment of this utility model, each of the four grooves has a column fixed to its inner wall, and the outer walls of the four columns slide against the inner wall of the protrusion.
[0010] As a preferred embodiment of this utility model, the adjusting mechanism includes:
[0011] Two sliders are provided, with the top of each slider located at the bottom of a concave plate. The top of the base has two sliding holes, the inner walls of which slide against the outer walls of the sliders. The bottom of each concave plate has a connecting groove, and the inner walls of each connecting groove are fitted with connecting blocks. The bottom of each connecting block is fixed to the top of the slider.
[0012] As a preferred technical solution of this utility model, the inner walls of the two sliders are threaded with lead screws, one end of each of the two lead screws is coaxially connected to a drive motor, the bottom end of each of the two drive motors is provided with a base plate, and one side of each of the two base plates is fixed to one side of the base.
[0013] As a preferred embodiment of this utility model, the inner walls of both sliding holes are fixed with horizontal columns, and the outer walls of both horizontal columns slide against the inner wall of the slider.
[0014] As a preferred embodiment of this utility model, a slot is provided on one side of each of the two connecting blocks, and a locking post is provided on the inner wall of each of the two slots. The outer wall of each locking post is fitted with the inner wall of the connecting slot.
[0015] The beneficial effects of this utility model are:
[0016] 1. This solution involves tensioning the sheet so that its two sides slide against the outer wall of the concave plate, controlling the clamping plate to slide on the outer surface of the concave plate, and allowing the protrusions fixed to the clamping plate to slide on the inner wall of the groove until the top of the clamping plate contacts the bottom of the sheet. The screw's outer wall and the hole plate's inner wall are then threaded together to gradually increase the height of the support plate until the top of the support plate contacts the bottom of the clamping plate. This allows the concave plate and clamping plate to be used together to limit and clamp the two sides of the sheet, ensuring that the sheet is stably tensioned above the base and preventing wrinkles from affecting the normal cutting of the laser cutting machine.
[0017] 2. In this solution, the inner wall of the connecting groove at the bottom of the concave plate is matched and installed with the connecting block fixed at the top of the slider. The power switch of the external control drive motor is turned on, causing the drive motor to drive the lead screw to rotate. In turn, the lead screw and the slider are connected by a threaded transmission, causing the slider to move linearly on the outer surface of the lead screw. This controls the concave plate to move back and forth at the top of the base, which makes it easy to adjust the distance between the two bases according to the length of the sheet. This facilitates more stable clamping and tightening of sheets of different lengths, avoiding the need for workers to repeatedly change the sheet clamping equipment. At the same time, after clamping sheets of different lengths, the device controls the concave plate to slide on the base so that it can move to the designated position to tension the sheet, thereby effectively improving the performance of the device.

Detailed Implementation
[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0025] Example: Figure 1-4 As shown, the present invention provides a sheet clamping and tightening mechanism for a laser cutting machine, including a base 1, two concave plates 2 sliding on the top of the base 1, a limiting mechanism 3 on the outer wall of the two concave plates 2, and an adjusting mechanism 4 on the outer wall of the base 1.
[0026] Limiting mechanism 3 includes:
[0027] Two clamping plates 31 are provided, and the outer walls of the two clamping plates 31 slide against the outer surface of the concave plate 2. Hole plates 32 are fixed on both sides of the two concave plates 2. Screws 33 are threaded on the inner walls of the four hole plates 32. Support plates 34 are fixed at the top of the four screws 33. The top of the four support plates 34 are located at the bottom of the clamping plates 31. Slide grooves 35 are provided on both sides of the two concave plates 2. Protrusions 36 slide on the inner walls of the four slide grooves 35. One side of the four protrusions 36 is fixed to the outer wall of the clamping plate 31. Columns 37 are fixed on the inner walls of the four slide grooves 35. The outer walls of the four columns 37 slide against the inner walls of the protrusions 36.
[0028] As attached Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the adjustment mechanism 4 includes:
[0029] Two sliders 41 are provided, with their top ends positioned at the bottom of the concave plate 2. The top of the base 1 has two sliding holes 42, the inner walls of which slide against the outer walls of the sliders 41. The bottom ends of the two concave plates 2 each have connecting grooves 43, and the inner walls of these grooves are fitted with connecting blocks 44. The bottom ends of these connecting blocks 44 are fixed to the top ends of the sliders 41. The inner walls of the two sliders 41 are threaded with lead screws 45, one end of which is coaxially connected to a drive motor 46. The bottom ends of the two drive motors 46 each have a base plate 47. One side of 7 is fixed to one side of the base 1. The inner walls of the two sliding holes 42 are fixed with horizontal columns 48. The outer walls of the two horizontal columns 48 slide against the inner wall of the slider 41. One side of the two connecting blocks 44 is provided with a slot 5. The inner walls of the two slots 5 are matched with a locking post 6. The outer walls of the two locking posts 6 are fitted with the inner wall of the connecting groove 43. This makes it easy to adjust the clamping tension of sheets of different lengths, avoids the need for workers to repeatedly replace the sheet clamping components, and facilitates better tensioning of the clamped sheet, avoiding the need for workers to manually tension the sheet, thus improving the practicality of the device.
[0030] Working principle: In use, the inner wall of the connecting groove 43 at the bottom of the concave plate 2 is matched and installed with the connecting block 44 fixed at the top of the slider 41. The power switch of the external control drive motor 46 is turned on, causing the drive motor 46 to drive the lead screw 45 to rotate. In turn, the lead screw 45 and the slider 41 are threadedly driven, causing the slider 41 to move linearly on the outer surface of the lead screw 45. This controls the concave plate 2 to move back and forth on the top of the base 1, which facilitates the adjustment of the distance between the two bases 1 according to the length of the sheet. This tensions the sheet so that its two sides slide against the outer wall of the concave plate 2, and controls the clamping plate 31 to slide on the outer surface of the concave plate 2. The protrusion 36, which is fixed to the clamping plate 31, slides on the inner wall of the groove 35 until the top of the clamping plate 31 contacts the bottom of the sheet. The screw 33 is threaded into the inner wall of the hole plate 32, so that the height of the support plate 34 is gradually increased until the top of the support plate 34 contacts the bottom of the clamping plate 31, thereby clamping and tightening the sheet. After the sheet is installed between the two concave plates 2, the drive motor 46 is controlled to drive the lead screw 45 to rotate, thus controlling the two concave plates 2 to slide on the top of the base 1, so as to adjust the position of the two concave plates 2 according to the sheet of different lengths, so that the sheet is kept taut above the base 1.
