Abstract
Description
Technical Field
[0001] This utility model relates to the field of security door processing technology, and in particular to a precision flexible polishing machine device for security doors. Background Technology
[0002] During the manufacturing process of security doors, grinding the edges is a crucial step in ensuring product quality and performance. After cutting or welding, security door edges are prone to developing metal burrs or sharp corners, which can cause injury or affect the seal upon direct contact. Grinding smooths the edges, improving safety and security.
[0003] Because security doors vary in length and width, but polishing tools are generally fixed, after polishing one edge of the security door, it is usually necessary to manually rotate the door so that the other side can fit smoothly onto the polishing tool. The heavy weight of security doors leads to low operational efficiency, further affecting the polishing efficiency. Utility Model Content
[0004] This utility model discloses a precision flexible polishing machine for security doors, which aims to solve the technical problem that manual flipping of security doors leads to low operating efficiency and further affects the polishing efficiency of security doors.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A precision flexible polishing machine for security doors includes a base, an electric linear guide rail is fixedly connected to the top outer wall of the base, a slider is movably connected to the electric linear guide rail, a support chamber is fixedly connected to the top outer wall of the slider, a motor is fixedly connected to the bottom inner wall of the support chamber, the output end of the motor passes through the support chamber and is fixedly connected to a support shaft, and a support plate is fixedly connected to the top of the support shaft.
[0007] The top outer wall of the base is fixedly connected to a bidirectional electric linear guide rail II. Two sliders II are symmetrically and movably connected to the bidirectional electric linear guide rail II. A correction mechanism is fixedly connected to the top outer wall of the two sliders II. A grinder is fixedly connected to one side outer wall of the correction mechanism. The two grinders are symmetrically distributed on both sides of the support chamber.
[0008] The top outer wall of the base is fixedly connected to an electric linear guide rail three via a connecting frame. A slider three is movably connected to the electric linear guide rail three, and a pressing mechanism is fixedly connected to the bottom end of the slider three.
[0009] The third electric linear guide is located directly above the first electric linear guide, and the second bidirectional electric linear guide is perpendicular to the first electric linear guide.
[0010] By placing the security door on top of the support plate and pressing the pressing mechanism on the top of the security door, the security door can be moved horizontally by the synchronous drive of the electric linear guide rail three and electric linear guide rail one, so that its edges can contact the grinders in sequence to complete the grinding of both sides. After the grinding is completed, the pressing mechanism is lifted, and the motor drives the support plate to rotate, thereby rotating the security door. The bidirectional electric linear guide rail two drives the grinders on both sides to move and fit against the other two sides of the security door. Then, the pressing mechanism presses down to complete the grinding of the other two sides. With this structure, manual flipping and control can be replaced, ensuring the grinding efficiency of the security door edges.
[0011] In a preferred embodiment, the correction mechanism includes a hollow limiting seat fixedly connected to the outer wall of the top end of the second slider, and an electric telescopic rod fixedly connected to the inner wall of the bottom end of the hollow limiting seat. An inner hollow slide is movably connected to the inner wall of the hollow limiting seat, and the output end of the electric telescopic rod is fixedly connected to the inner wall of the inner hollow slide.
[0012] The top outer wall of the hollow slide is fixedly connected to a support frame two, and the grinder is fixedly connected to one end of the support frame two. A reinforcing rib is fixedly connected between one side outer wall of the support frame two and one side outer wall of the grinder. An L-shaped bracket is fixedly connected to the bottom outer wall of the grinder, and a pressure sensing plate is fixedly embedded in one side inner wall of the L-shaped bracket.
[0013] With a calibration mechanism, before polishing, the electric telescopic rod extends, moving the pressure sensing plates to the original height of the polisher. Then, the two pressure sensing plates are moved to fit against both sides of the security door by the second bidirectional electric linear guide. The position of the security door is determined by monitoring the pressure of the pressure sensing plates. Then, driven by the second bidirectional electric linear guide, the plate moves back and contacts both sides of the security door again. The movement position of the polisher is determined by monitoring the pressure, thus achieving flexible polishing. In addition, it can also prevent the polisher from directly pushing the security door and causing damage to the surface of the security door.
[0014] In a preferred embodiment, the pressing mechanism includes a connecting plate 1 fixedly connected to the outer wall of the bottom end of the slider 3, and a gas rod 1 fixedly connected to the outer wall of the bottom end of the connecting plate 1. The output end of the gas rod 1 is fixedly connected to a connecting plate 2, and a support frame 1 is fixedly connected to the outer wall of the bottom end of the connecting plate 2.
[0015] The support frame 1 is provided with both slide groove 1 and slide groove 2, and slide groove 1 is fixedly connected to the top of slide groove 2. Slide slider 4 is movably connected in slide groove 1, and slide slider 5 is movably connected in slide groove 2.
[0016] The fourth slider is fixedly connected to the top outer wall of the fifth slider. Springs are fixedly connected to the opposite outer walls of the fourth slider, and the other end of the springs is fixedly connected to the inner wall of the first groove. A pressing plate is fixedly connected to the bottom outer wall of the fifth slider, and multiple protrusions are fixedly connected to the bottom end of the pressing plate.
[0017] With the addition of a pressing mechanism, as the security door moves horizontally under the push of the correction mechanism, the pressing plate also moves horizontally under the guidance of slide rail one and slide rail two. This allows for upper pressing limit during the correction process, preventing the security door from falling due to instability of the center of gravity.
[0018] As described above, a precision flexible polishing machine for security doors includes a base. An electric linear guide rail is fixedly connected to the top outer wall of the base, and a slider is movably connected to the electric linear guide rail. A support chamber is fixedly connected to the top outer wall of the slider, and a motor is fixedly connected to the bottom inner wall of the support chamber. The output end of the motor passes through the support chamber and is fixedly connected to a support shaft, with a support plate fixedly connected to the top of the support shaft. A bidirectional electric linear guide rail is also fixedly connected to the top outer wall of the base. Two sliders are symmetrically movably connected to the bidirectional electric linear guide rail, and a correction mechanism is fixedly connected to the top outer wall of the two sliders. A polisher is fixedly connected to one side outer wall of the correction mechanism, and two polishers are symmetrically distributed on both sides of the support chamber. An electric linear guide rail is fixedly connected to the top outer wall of the base via a connecting frame. A slider is movably connected to the electric linear guide rail, and a pressing mechanism is fixedly connected to the bottom of the slider.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] The precision flexible polishing machine device for security doors disclosed in this utility model is mainly used in the polishing of security doors.
[0026] Reference Figure 1 and Figure 2 A precision flexible polishing machine for security doors includes a base 3. An electric linear guide rail 2 is fixedly connected to the top outer wall of the base 3. A slider 14 is movably connected to the electric linear guide rail 2. A support chamber 4 is fixedly connected to the top outer wall of the slider 14. A motor 13 is fixedly connected to the bottom inner wall of the support chamber 4. A support shaft 12 is fixedly connected to the output end of the motor 13 through the support chamber 4. A support plate 11 is fixedly connected to the top of the support shaft 12.
[0027] The top outer wall of the base 3 is also fixedly connected to a bidirectional electric linear guide rail 2 5. Two sliders 2 15 are symmetrically and movably connected on the bidirectional electric linear guide rail 2 5. The top outer wall of the two sliders 2 15 is fixedly connected to a correction mechanism 6. A grinder 7 is fixedly connected to one side outer wall of the correction mechanism 6. The two grinders 7 are symmetrically distributed on both sides of the support chamber 4.
[0028] The top outer wall of the base 3 is fixedly connected to an electric linear guide rail 39 via a connecting bracket 8. A slider 30 is movably connected to the electric linear guide rail 39, and a pressing mechanism 1 is fixedly connected to the bottom end of the slider 310. By placing the security door above the support plate 11 and pressing it down on the top of the security door by the pressing mechanism 1, the security door is stabilized on the support plate 11. Then, with the synchronous drive of the electric linear guide rail 39 and the electric linear guide rail 12, the security door can be pushed to move horizontally, so that its edges sequentially contact the grinder 7 to complete the grinding of both sides. After the grinding is completed, the pressing mechanism... When structure 1 is lifted, the support plate 11 is rotated by motor 13, which in turn rotates the security door. Before this, the two-way electric linear guide 2 5 drives the polishers 7 on both sides to move outward. After the security door finishes rotating, the polishers 7 on both sides move inward simultaneously by the two-way electric linear guide 2 5, so that they fit against the other two sides of the security door. Then, after the pressing mechanism 1 presses down, the other two sides can be polished by the synchronous drive of electric linear guide 3 9 and electric linear guide 1 2. With this structure, manual flipping and control can be replaced, ensuring the polishing efficiency of the security door edges.
[0029] Reference Figure 1 In a preferred embodiment, the electric linear guide 39 is located directly above the electric linear guide 12, and the bidirectional electric linear guide 25 is perpendicular to the electric linear guide 12.
[0030] Reference Figure 3 In a preferred embodiment, the correction mechanism 6 includes a hollow limiting seat 601 fixedly connected to the outer wall of the top of the slider 2 15, and an electric telescopic rod 602 fixedly connected to the inner wall of the bottom end of the hollow limiting seat 601. An inner hollow slide 603 is movably connected to the inner wall of the hollow limiting seat 601, and the output end of the electric telescopic rod 602 is fixedly connected to the inner wall of the inner hollow slide 603.
[0031] Reference Figure 3In a preferred embodiment, a support frame 604 is fixedly connected to the top outer wall of the hollow slide 603, and the grinder 7 is fixedly connected to one end of the support frame 604. A reinforcing rib 605 is fixedly connected between one side outer wall of the support frame 604 and one side outer wall of the grinder 7. An L-shaped bracket 607 is fixedly connected to the bottom outer wall of the grinder 7, and a pressure sensing plate 606 is fixedly embedded in one side inner wall of the L-shaped bracket 607. Before grinding, the electric telescopic rod 602 extends, pushing the hollow slide 603 vertically upward under the longitudinal limitation of the hollow limiting seat 601, thus stimulating the pressure sensing plate. The pressure plate 606 moves to the original height of the grinder 7, and then, driven by the bidirectional electric linear guide 2 5, drives the two pressure sensing plates 606 to fit against both sides of the security door. Throughout the process, the position of the security door is determined by monitoring the pressure of the pressure sensing plates 606. When the pressure is continuously increased and the bidirectional electric linear guide 2 5 is close to stopping, the security door is in the correct position. Then, driven by the bidirectional electric linear guide 2 5, it moves back and contacts both sides of the security door again. The movement position of the grinder 7 is determined by monitoring the pressure, so as to achieve flexible grinding. In addition, it can also avoid the grinder 7 directly pushing the security door and causing damage to the surface of the security door.
[0032] Reference Figure 4 In a preferred embodiment, the pressing mechanism 1 includes a connecting plate 101 fixedly connected to the bottom outer wall of the slider 3 10, and a gas rod 102 fixedly connected to the bottom outer wall of the connecting plate 101. The output end of the gas rod 102 is fixedly connected to a connecting plate 2 103, and a support frame 104 is fixedly connected to the bottom outer wall of the connecting plate 2 103.
[0033] Reference Figure 4 In a preferred embodiment, the support frame 104 is provided with both a first slide groove 105 and a second slide groove 106. The first slide groove 105 is fixedly connected to the top of the second slide groove 106. A fourth slider 110 is movably connected in the first slide groove 105, and a fifth slider 109 is movably connected in the second slide groove 106.
[0034] Reference Figure 4In a preferred embodiment, slider four 110 is fixedly connected to the top outer wall of slider five 109. Springs 111 are fixedly connected to the opposite outer walls of slider four 110, and the other end of each spring 111 is fixedly connected to the inner wall of the slide groove one 105. A pressing plate 107 is fixedly connected to the bottom outer wall of slider five 109, and multiple protrusions 108 are fixedly connected to the bottom of the pressing plate 107. Before the correction mechanism 6 moves inward to correct, the pressing mechanism 1 first presses against the top of the security door. The security door moves horizontally under the push of the calibration mechanism 6, and the pressing plate 107 also moves horizontally under the guidance of the first slide 105 and the second slide 106. At the same time, the spring 111 is deformed, which can realize the upper pressing limit during the calibration process, and prevent the security door from falling due to the unstable center of gravity during the calibration process. When the calibration mechanism 6 clamps, the gas spring 102 is raised and pressed down again, so that the pressing plate 107 is kept in the middle position and pressed down. Then, when the calibration mechanism 6 moves back and contacts again, the accuracy of pressure sensing can be guaranteed.
[0035] Working principle: By placing the security door on top of the support plate 11 and pressing it down on the top of the security door by the pressing mechanism 1, the security door is stabilized on the support plate 11. Then, with the synchronous drive of the electric linear guide rail 3 9 and the electric linear guide rail 1 2, the security door can be pushed to move horizontally, so that its edges sequentially contact the grinders 7 to complete the grinding of both sides. After grinding, the pressing mechanism 1 is lifted, and the motor 13 drives the support plate 11 to rotate, thereby driving the security door to rotate. Before this, the bidirectional electric linear guide rail 2 5 drives the grinders 7 on both sides to move outward. After the security door rotates, the bidirectional electric linear guide rail 2 5 drives the grinders 7 on both sides to move inward simultaneously to fit against the other two sides of the security door. After the pressing mechanism 1 presses down, the synchronous drive of the electric linear guide rail 3 9 and the electric linear guide rail 1 2 can achieve the grinding of the other two sides. With this structure, manual flipping and control can be replaced, ensuring the grinding efficiency of the security door edges.
[0036] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
