Description

Technical Field

[0001] The invention relates to the technical field of aluminum plates, in particular to a clamping base for processing aluminum plates. Background Art

[0002] In the field of aluminum plate processing, with the continuous development of the manufacturing industry, aluminum plates are widely used in many industries such as construction, automobiles, aerospace, and electronic equipment due to their many advantages such as light weight, high strength, and easy processing and forming. In the processing of aluminum plates, such as cutting, drilling, milling, welding and other processes, stable and precise clamping of aluminum plates is the key link to ensure processing quality and efficiency; At present, many clamping bases on the market have low adaptability when facing aluminum plates of different lengths and shapes (especially those with corners, special curvatures and other special-shaped structures). The clamping spacing of some clamps is fixed and cannot be flexibly adjusted according to the actual length of the aluminum plate. When processing aluminum plates of different specifications, different clamps often need to be replaced, which increases the processing cost and time cost. In addition, for aluminum plates with special shapes, it is difficult for existing clamping devices to find a suitable focus point for stable clamping, which limits its application in diversified aluminum plate processing scenarios. After searching, the applicant found that a Chinese patent disclosed "a clamping device for aluminum plate processing", and its publication (announcement) number is "CN 215968346 U". This patent mainly rotates the first screw or the second screw to move the threaded sleeve to one side, and at the same time drives the adjustment plate to move and clamp the aluminum plate, and rotates the adjustment rod according to demand to fix the extrusion plate to the top of the aluminum plate. Not only is the adjustment method more flexible and simple, but the clamping effect is also better. However, the device cannot clamp and fix the aluminum plate in the center, and the aluminum plate is prone to tilt or shake during processing. In addition, the device cannot clamp and fix aluminum plates with corners, and has low adaptability. For this reason, we propose a clamping base for aluminum plate processing. Summary of the invention

[0003] The object of the present invention is to provide a clamping base for processing aluminum plates.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a clamping base for aluminum plate processing, comprising an L-shaped support frame and a clamping mechanism, and also comprising an adjustment seat for supporting the clamping mechanism, wherein the clamping mechanism and the adjustment seat are each provided with two, and the two adjustment seats are respectively slidably mounted on the top of both ends of the L-shaped support frame, and two groups of the clamping mechanisms are rotatably arranged in the corresponding adjustment seats, the clamping mechanism comprises a base plate, a rotating connecting rod, two clamping plates, a slider 1, a transmission connecting rod and a handle, screws are provided at both ends of the base plate, an arc-shaped through groove corresponding to the screw is opened on the side of the adjustment seat, the screw is based on the center of the adjustment seat, and rotates along the arc-shaped through groove with the adjustment seat, the middle part of the rotating connecting rod is rotatably arranged in the middle of the top of the base plate, the two clamping plates are detachably connected to the top of the outer end of the corresponding slider 1, the two sliders 1 are respectively slidably connected to the left and right ends of the base plate, and the slider 1 is transmission-connected to the rotating connecting rod through the transmission connecting rod, and the two handles are respectively connected to the screws at the left and right ends of the base plate, and the clamping mechanism also includes a driving component for driving the rotating connecting rod to rotate.

[0005] As a further solution of the present invention: linear guide rails are provided at both ends of the top of the L-shaped support frame, and a sliding block 2 that matches the linear guide rails is provided at the bottom of the adjustment seat.

[0006] As a further solution of the present invention: the driving component includes a stepping motor, and the stepping motor is detachably arranged in the middle of the bottom of the substrate.

[0007] As a further solution of the present invention: the position near the top of the stepper motor output end is rotatably connected to a bearing provided in the middle of the base plate, and the top of the stepper motor output end is key-connected to the middle of the rotating connecting rod.

[0008] As a further solution of the present invention: the tops of the left and right ends of the base plate are both provided with sliding grooves, and the bottom of the sliding block is engaged with the sliding grooves for sliding.

[0009] As a further solution of the present invention: a pivot provided at the top of an inner end of the slider is rotatably connected to one end of a transmission connecting rod, and the other end of the transmission connecting rod is rotatably connected to a pivot provided at the top of the rotating connecting rod.

[0010] As a further solution of the present invention: the two transmission connecting rods are symmetrically arranged at the left and right ends of the rotating connecting rod with the center of the rotating connecting rod as a reference.

[0011] As a further solution of the present invention: support blocks are provided on both the front and rear sides of the middle of the base plate, and universal wheels are installed at the bottom of the end of the support blocks. The universal wheels are slidably installed in the annular guide rail provided at the bottom of the adjustment seat.

[0012] As a further solution of the present invention: a V-shaped clamping block is provided on the inner side of the clamping plate, and the V-shaped clamping block is installed on the inner side of the clamping plate in a detachable connection manner.

[0013] By adopting the above technical solution, compared with the prior art, the beneficial effects of the present invention are: 1. The clamping mechanism designed in the present invention can position the center of gravity of the aluminum plate on the center line of the clamping mechanism, which helps to improve the stability of the entire clamping system. When the stepper motor rotates forward, the top of its output end is keyed to the middle of the rotating connecting rod, and the rotating connecting rod rotates clockwise. The two ends of the rotating connecting rod are connected to the transmission connecting rod through a pivot rotation. The other end of the transmission connecting rod is pivotally connected to the inner end of the slider. The bottom of the slider slides in the base plate slot. When the rotating connecting rod rotates, the transmission connecting rod pushes the slider to move inward in the slot. Since the two sliders are at the left and right ends of the base plate and the transmission connecting rod is symmetrically arranged, the two slide synchronously in the centering direction, driving the clamping plate at the outer end to move synchronously, so that the V-shaped clamping blocks on the inner side of the clamping plate move toward each other, thereby achieving centering clamping and fixing of the aluminum plate. 2. The L-shaped support frame designed in the present invention can effectively meet the clamping requirements of aluminum plates of different shapes. The special shape of the L-shaped support frame provides adaptability to aluminum plates with corners. When encountering an aluminum plate with a corner, a part of the aluminum plate can be placed on the clamping mechanism at one end of the L-shaped support frame, and the other part can be placed on the clamping mechanism at the other end of the L-shaped support frame; 3. The present invention can effectively cope with the clamping requirements of aluminum plates of different lengths through the designed adjustment seat, further improving the adaptability of the clamping base. When it is necessary to clamp aluminum plates of different lengths, the adjustment seat can be manually pushed to slide along the linear guide rail. Since the two sets of clamping mechanisms are respectively installed on two slidable adjustment seats, as the adjustment seats slide, the distance between the two sets of clamping mechanisms will change. In this way, the two sets of clamping mechanisms can be adjusted to the appropriate position according to the length of the aluminum plate, and at the same time, they can correspond to the two ends of the aluminum plate.

[0014] Other advantages, objectives and features of the present invention will be set forth in part in the following description and, in part, will be apparent to those skilled in the art based on an examination of the following or may be taught from the practice of the present invention.

[0017] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0018] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0019] Please see attached Figure 1 -Attached Figure 8The present invention provides a clamping base for aluminum plate processing, comprising an L-shaped support frame 1 and a clamping mechanism 2, and also comprising an adjustment seat 3 for supporting the clamping mechanism 2. The clamping mechanism 2 and the adjustment seat 3 are each provided with two, and the two adjustment seats 3 are respectively slidably installed on the top of the two ends of the L-shaped support frame 1, and the two groups of clamping mechanisms 2 are rotatably arranged in the corresponding adjustment seats 3. The clamping mechanism 2 comprises a base plate 21, a rotating connecting rod 22, two clamping plates 23, a slider 24, a transmission connecting rod 25 and a handle 26. Screws 211 are provided at both ends of the base plate 21. An arc-shaped through groove 301 corresponding to the screw 211 is opened on the side of the adjustment seat 3. The curvature and position of the arc-shaped through groove 301 can be opened according to actual needs. The screw 211 is based on the center of the adjustment seat 3, and rotates along the arc-shaped through groove 301 to fit with the adjustment seat 3. The middle part of the rotating connecting rod 22 can rotate The base plate 21 is arranged in the middle of the top of the base plate 21, and the two clamping plates 23 are detachably connected to the top of the outer end of the corresponding slider 24. The two sliders 24 are slidably connected to the left and right ends of the base plate 21, and the slider 24 is transmission-connected to the rotating link 22 through the transmission link 25. The two handles 26 are respectively connected to the screw rods 211 at the left and right ends of the base plate 21. When the clamping mechanism 2 is adjusted to a suitable angle, the handles 26 can be tightened, and the screw rods 211 will be fixed in a specific position of the arc-shaped through groove 301. At this time, the handles 26 at both ends will be tightly attached to the outer wall of the adjustment seat 3. This close fit generates sufficient friction and pressure, thereby preventing the clamping mechanism 2 from rotating and moving in the adjustment seat 3, thereby realizing stable and reliable fixation of the clamping mechanism 2. The clamping mechanism 2 also includes a driving component for driving the rotating link 22 to rotate.

[0020] In the first embodiment, both ends of the top of the L-shaped support frame 1 are provided with linear guide rails 101, and the bottom of the adjustment seat 3 is provided with a second slider 302 that matches the linear guide rails 101; Specifically, the structure in which the guide rail cooperates with the slider enables the adjustment seat 3 to slide on the top of both ends of the L-shaped support frame 1. When it is necessary to clamp aluminum plates of different lengths, the adjustment seat 3 can be manually pushed to slide along the linear guide rail 101. Since the two groups of clamping mechanisms 2 are respectively mounted on two slidable adjustment seats 3, as the adjustment seat 3 slides, the distance between the two groups of clamping mechanisms 2 will change. In this way, the two groups of clamping mechanisms 2 can be adjusted to appropriate positions according to the length of the aluminum plate, so that they can correspond to the two ends of the aluminum plate, preparing for subsequent clamping operations. In addition, the special shape of the L-shaped support frame 1 provides adaptability to aluminum plates with corners. When encountering aluminum plates with corners, part of the aluminum plate It can be placed on the clamping mechanism 2 at one end of the L-shaped support frame 1, and the other part can be placed on the clamping mechanism 2 at the other end of the L-shaped support frame 1. The two groups of clamping mechanisms 2 are respectively installed at the two ends of the L-shaped support frame 1. By sliding the adjustment seat 3 on the top of the two ends of the L-shaped support frame 1 and rotating the clamping mechanism 2 in the adjustment seat 3, the two groups of clamping mechanisms 2 can be respectively located at the appropriate positions of the two parts of the corner aluminum plate, and then the clamping function of the clamping mechanism 2 is utilized to clamp the two parts of the corner aluminum plate from two different directions, thereby realizing the fixation of the aluminum plate with a corner. This design makes full use of the shape characteristics of the L-shaped support frame 1 and the adjustability of the adjustment seat 3 and the clamping mechanism 2, and can effectively meet the clamping needs of aluminum plates of different shapes.

[0021] In the second embodiment, the driving component includes a stepper motor 27, which is detachably arranged in the middle of the bottom of the base plate 21. The output end of the stepper motor 27 is rotatably connected to the bearing provided in the middle of the base plate 21 at a position close to the top, and the top of the output end of the stepper motor 27 is key-connected to the middle of the rotating link 22. Slide grooves 212 are provided at the tops of both left and right ends of the base plate 21. The bottom of the slider 24 is engaged and slidably engaged with the slide groove 212. The pivot provided at the top of the inner end of the slider 24 is rotatably connected to one end of the transmission link 25, and the other end of the transmission link 25 is rotatably connected to the pivot provided at the top of the rotating link 22. The two transmission links 25 are symmetrically arranged at the left and right ends of the rotating link 22 with the center of the rotating link 22 as the reference. Specifically, when the stepper motor 27 is clocked, since the top of the output end of the stepper motor 27 is keyed to the middle of the rotating link 22, the rotating link 22 will rotate clockwise accordingly, and the two ends of the rotating link 22 are rotationally connected to the transmission link 25 through a pivot, and the other end of the transmission link 25 is rotationally connected to the pivot at the top of the inner end of the slider 24, and the bottom of the slider 24 is engaged and slid with the slide groove 212 opened at the top of the left and right ends of the base plate 21, limiting the slider 24 to move only along the direction of the slide groove 212. As the rotating link 22 rotates clockwise, the transmission link 25 will push the slider 24 to slide inward in the slide groove 212 of the base plate 21. Because the two sliders 24 are respectively located at the left and right ends of the base plate 21, and the two transmission links 25 are symmetrically arranged at the left and right ends of the rotating link 22 with the center of the rotating link 22 as the reference, the two sliders 24 can move inward synchronously.

[0022] In the third embodiment, support blocks 213 are provided on both sides of the front and rear of the middle of the base plate 21, and a universal wheel 28 is installed at the bottom of the end of the support block 213. The universal wheel 28 is slidably installed in the annular guide rail 303 provided at the bottom of the adjustment seat 3, and a V-shaped clamping block 29 is provided on the inner side of the clamping plate 23. The V-shaped clamping block 29 is installed on the inner side of the clamping plate 23 in a detachable connection manner; Specifically, the universal wheel 28 slides in the annular guide rail 303 at the bottom of the adjustment seat 3, which provides more flexible support for the rotation of the clamping mechanism 2 and further ensures the smoothness of the rotation. The top of the outer end of the slider 24 is detachably connected to the clamping plate 23. When the slider 24 moves inward, the two clamping plates 23 will also move inward synchronously. A V-shaped clamping block 29 is provided on the inner side of the clamping plate 23. The two V-shaped clamping blocks 29 move toward each other, so that the aluminum plate placed between them can be clamped and fixed.

[0023] Working principle: First, according to the style of the aluminum plate, adjust the positions of the clamping mechanism 2 and the adjustment seat 3 on the L-shaped support frame 1. The clamping mechanism 2 cooperates with the arc-shaped through groove 301 on the side of the adjustment seat 3 through the screws 211 at the left and right ends of the base plate 21. The screw 211 can rotate in the arc-shaped through groove 301 with the center of the adjustment seat 3 as the reference, so that the clamping mechanism 2 can rotate in the adjustment seat 3. When the clamping mechanism 2 is adjusted to a suitable angle, the handle 26 can be tightened, and the screw 211 will be fixed in a specific position of the arc-shaped through groove 301; Secondly, by manually pushing the adjustment seat 3 to slide along the linear guide rail 101, as the adjustment seat 3 slides, the distance between the two sets of clamping mechanisms 2 will change, so that the two sets of clamping mechanisms 2 can be adjusted to a suitable position according to the length of the aluminum plate, so that they can correspond to the two ends of the aluminum plate, preparing for the subsequent clamping operation; Finally, the stepper motor 27 rotates forward, the rotating link 22 rotates clockwise, and the two ends of the rotating link 22 are rotatably connected to the transmission link 25 through a pivot. The other end of the transmission link 25 is connected to the pivot at the top of the inner end of the slider 24, and the bottom of the slider 24 is engaged and slid with the slide grooves 212 opened at the top of the left and right ends of the base plate 21, which restricts the slider 24 to move only along the direction of the slide groove 212. As the rotating link 22 rotates clockwise, the transmission link 25 pushes the slider 24 to slide inward in the slide groove 212 of the base plate 21. The two sliders 24 are respectively located at the left and right ends of the base plate 21, and the two transmission connecting rods 25 are symmetrically arranged at the left and right ends thereof with the center of the rotating connecting rod 22 as the reference, so the two sliders 24 can move inward synchronously, and the top of the outer end of the slider 24 is detachably connected to the clamping plate 23. When the slider 24 moves inward, the two clamping plates 23 move inward synchronously, and the V-shaped clamping blocks 29 on the inner sides of the clamping plates 23 move toward each other, thereby centering and clamping the aluminum plate placed between them. At this point, the entire workflow is completed.
