Description

Technical Field

[0001] The utility model belongs to the field of cutting and processing of polymethacrylimide foam, and particularly relates to an adjustable cutting device. Background Technique

[0002] Polymethacrylimide (PMI) foam is a lightweight and high-performance foam material with excellent mechanical properties and high-temperature resistance. PMI foam is usually used in aerospace, aircraft, and other high-performance applications, and is favored because of its light weight, high strength, and excellent insulation properties; the cutting and processing of PMI foam usually refers to cutting, forming, or processing this material for use in the fields of manufacturing aviation parts, model making, spacecraft components, etc. Cutting and processing can adopt a variety of methods, including but not limited to numerical control cutting, grinding, cutting, milling, and other processes. These processing methods need to be selected according to specific application requirements and the characteristics of PMI foam to ensure that the final product can meet the design requirements.

[0003] When traditional polymethacrylimide foam substrates are cut, they are mostly cut and processed by cutting equipment. For example, a Chinese published patent with a patent number of CN212421397U points out a cutting and blanking device; in this cited document, the polymethacrylimide foam is driven by a conveyor belt to move a certain distance and then stop, and the hydraulic rod pushes the blade downward to cut the polymethacrylimide foam and then retracts back to its original position.

[0004] In actual use, although the above-cited patent realizes the cutting of polymethacrylimide foam, it still has certain limitations in use, that is, the cutting blade in this document can only perform vertical lifting cutting, and the cutting range is limited. In the actual processing environment, it cannot meet the processing requirements of complex-shaped or large-sized workpieces. At the same time, due to the single cutting range, multiple adjustments and cuts are required in actual processing operations to complete the processing of the entire workpiece, resulting in low processing efficiency. Therefore, an adjustable cutting device is proposed to solve the cutting method in the cited document. Summary of the Utility Model

At both ends of the moving beam platform, a group of transverse adjustment reciprocating motors are assembled respectively. The output end of the transverse adjustment reciprocating motor is connected with a gear. The gears connected by the two groups of transverse adjustment reciprocating motors respectively engage with the teeth on one of the side tooth rails.

[0012] As a further improvement of the present utility model, a horizontal adjustment reciprocating motor is assembled on the upper end face of the tool holder.

On the upper end face of the moving beam platform, a horizontal tooth rail is assembled transversely along it. The gear disc connected by the horizontal adjustment reciprocating motor engages with the teeth on the horizontal tooth rail.

[0013] As a further improvement of the present utility model, the propulsion assembly further includes ball bearings arranged in the two positioning plates. The two ends of the threaded lead screw are respectively rotatably connected with one of the ball bearings. One end of the side positioning seat is assembled with a reciprocating motor. The output end of the reciprocating motor is connected with one end of the threaded lead screw.

[0014] As a further improvement of the present utility model, two limit guide rails are installed on the side faces of the side positioning seats in both groups of the propulsion assemblies.

[0022] Embodiment

[0023] ByFigures 1-3 Provided is an adjustable cutting device, including a polymethacrylimide foam cutting table 1;

[0024] On the upper end surface of the polymethacrylimide foam cutting table 1, two sets of propulsion components 2 and two support seats 101 are arranged in parallel along its transverse direction;

[0025] On the upper end surfaces of the two support seats 101, linear guide rails 3 are supported along their transverse directions. On the upper end surfaces of the two linear guide rails 3, rail sliders 4 are slidably arranged. Between the two rail sliders 4, a moving beam table 5 is jointly carried;

[0026] The moving beam table 5 is erected above the polymethacrylimide foam cutting table 1, and two side limit guide rails 8 are installed on its side surface. Sliders are slidably arranged on the two side limit guide rails 8, and a tool holder 9 is jointly carried through them; A linear lead screw module 12 is assembled on the tool holder 9. The linear lead screw module 12 is arranged vertically, and a cutting tool 13 is assembled on it;

[0027] Both sets of propulsion components 2 include side positioning seats 21 arranged on the upper end surface of the polymethacrylimide foam cutting table 1. On the side surfaces of the two side positioning seats 21, two positioning plates 22 are arranged. Between the two positioning plates 22, a threaded lead screw 24 is rotatably arranged. An external thread of the threaded lead screw 24 is engaged with a slider seat 25. Between the two slider seats 25, a propulsion plate 26 is installed; The propulsion plate 26 is arranged perpendicular to the polymethacrylimide foam cutting table 1 and is in contact with the upper end surface of the polymethacrylimide foam cutting table 1.

[0028] In this embodiment, during actual use, the provided cutting tool 13 can be accurately positioned and adjusted in the horizontal and vertical directions. In cooperation with the movement adjustment of the linear lead screw module 12 in the vertical direction of the cutting tool 13, finally, multi-directionally adjustable cutting operations on the polymethacrylimide foam substrate can be realized by using the cutting tool 13, so as to meet the processing requirements of complex workpieces; and the linear lead screw module 12 on the tool holder 9 can realize the vertical control of the cutting tool 13, ensuring the accurate control of the cutting depth and cutting quality, thereby further improving the processing accuracy and stability. Compared with the single processing direction in the cited document, the cutting device of the present application can realize accurately adjustable cutting operations on the polymethacrylimide foam substrate in the three-axis directions, and improve production efficiency and reduce processing time.

[0029] Specifically, referring to Figures 1-2 , on the opposite side surfaces of the two support seats 101, side tooth rails 6 are assembled along their transverse directions; At both ends of the moving beam table 5, a set of transverse adjustment reciprocating motors 7 are assembled respectively. The output ends of the transverse adjustment reciprocating motors 7 are connected with gears. The gears connected by the two sets of transverse adjustment reciprocating motors 7 are respectively engaged with the teeth on one of the side tooth rails 6.

[0030] In this embodiment, the user connects a power supply to the horizontal adjustment reciprocating motor 7 and controls the rotation of the output end of the horizontal adjustment reciprocating motor 7. When the output end of the horizontal adjustment reciprocating motor 7 rotates, through the engagement between the gear connected to its output end and the side tooth rail 6, and in cooperation with the linear guide 3 and the guide rail slider 4 to support the moving beam table 5, the moving beam table 5 can move linearly along the stroke range of the side tooth rail 6.

[0031] Specifically, referring to Figures 1-2 , a horizontal adjustment reciprocating motor 11 is assembled on the upper end surface of the tool holder 9, and a gear disc is connected to the output end of the horizontal adjustment reciprocating motor 11; a horizontal tooth rail 10 is assembled along the transverse direction on the upper end surface of the moving beam table 5, and the gear disc connected to the horizontal adjustment reciprocating motor 11 engages with the teeth on the horizontal tooth rail 10.

[0032] In this embodiment, the user connects a power supply to the horizontal adjustment reciprocating motor 11 and controls the rotation of the output end of the horizontal adjustment reciprocating motor 11. When the output end of the horizontal adjustment reciprocating motor 11 rotates, through the engagement between the gear disc connected to its output end and the horizontal tooth rail 10, the tool holder 9 can perform a linear motion on the moving beam table 5.

[0033] Furthermore, by controlling the number of rotation cycles of the horizontal adjustment reciprocating motor 7 and the horizontal adjustment reciprocating motor 11, the precise position adjustment of the cutting tool 13 can be finally realized, and the cutting tool 13 can be precisely positioned and adjusted in the horizontal and vertical directions, so as to realize multi-directional cutting of the polymethacrylimide foam substrate.

[0034] Even further, in actual use, the power connection method between the horizontally adjustable reciprocating motor 7 and the horizontally adjustable reciprocating motor 11 is an existing technology, and the control circuit can be realized by simple programming by those skilled in the art, which belongs to the common knowledge in the field. Only its use is carried out without modification, so the control method and circuit connection will not be described in detail.

[0035] Specifically, referring to Figure 3 , the propulsion assembly 2 further includes ball bearings 23 arranged in two positioning plates 22, and both ends of the threaded lead screw 24 are respectively rotatably connected to one of the ball bearings 23; one end of the side positioning seat 21 is assembled with a reciprocating motor 28, and the output end of the reciprocating motor 28 is connected to one end of the threaded lead screw 24.

[0036] In this embodiment, when the reciprocating motor 28 rotates, the threaded lead screw 24 connected to its output end can rotate synchronously. At the same time, through the assembly between the ball bearing 23 and the threaded lead screw 24, the threaded lead screw 24 rotates more smoothly.

[0037] Specifically, referring to Figure 3, on the side surfaces of the side positioning seats 21 in the two sets of propulsion components 2, two limiting rails 27 are installed. A notch adapted to the limiting rail 27 is formed on the side surface of the slider seat 25, and the slider seat 25 is fitted and slidably connected with the limiting rail 27.

[0038] In this embodiment, when the threaded lead screw 24 rotates, due to the fitting connection between the limiting rail 27 and the slider seat 25, the slider seat 25 can drive the propulsion plate 26 to move linearly along the stroke range of the threaded lead screw 24.

[0039] Furthermore, through the arranged propulsion plate 26, the pushing of the polymethacrylimide foam substrate can be realized, so that the cut polymethacrylimide foam substrate can be pushed out on the polymethacrylimide foam cutting table 1, thereby completing rapid blanking.

[0040] The adjustable cutting device of the present utility model:

[0041] The first step: In actual processing and use, the user places the polymethacrylimide foam substrate to be cut and processed on the upper end surface of the polymethacrylimide foam cutting table 1; then adjusts the linear lead screw module 12, so that the linear lead screw module 12 can drive the cutting tool 13 to move downward, thereby using the cutting tool 13 to complete the cutting operation on the polymethacrylimide foam substrate;

[0042] The second step: During the cutting operation, the user connects the power supply to the lateral adjustment reciprocating motor 7 and the horizontal adjustment reciprocating motor 11 and controls the rotation of the output ends of the lateral adjustment reciprocating motor 7 and the horizontal adjustment reciprocating motor 11. When the output end of the lateral adjustment reciprocating motor 7 rotates, through the engagement between the gear connected to its output end and the side tooth rail 6, and with the support of the linear guide rail 3 and the guide rail slider 4 for the moving beam table 5, the moving beam table 5 can move linearly along the stroke range of the side tooth rail 6; at the same time, when the output end of the horizontal adjustment reciprocating motor 11 rotates, through the engagement between the gear disc connected to its output end and the horizontal tooth rail 10, the tool holder 9 can perform a linear motion on the moving beam table 5. By controlling the number of rotation cycles of the lateral adjustment reciprocating motor 7 and the horizontal adjustment reciprocating motor 11, the precise position adjustment of the cutting tool 13 can be finally realized, and the cutting tool 13 can be accurately positioned and adjusted in the horizontal and vertical directions, thereby realizing the multi-directional cutting of the polymethacrylimide foam substrate, meeting the processing requirements of complex workpieces, and the linear lead screw module 12 on the tool holder 9 can realize the vertical control of the cutting tool 13, ensuring the precise control of the cutting depth and cutting quality, thereby further improving the processing accuracy and stability;

[0043] Step 3: After the polymethacrylimide foam substrate is cut, the user controls the linear lead screw module 12 to move the cutting tool 13 upward. Subsequently, the output end of the reciprocating motor 28 is controlled to rotate. When the reciprocating motor 28 rotates, the threaded lead screw 24 connected to its output end can rotate synchronously. At this time, due to the fitting connection between the limit rail 27 and the slider seat 25, the slider seat 25 can drive the push plate 26 to move linearly along the stroke range of the threaded lead screw 24, so that the polymethacrylimide foam substrate can be pushed through the push plate 26, and the cut polymethacrylimide foam substrate can be pushed out on the polymethacrylimide foam cutting table 1, thus completing the blanking.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
