Description

Technical Field

[0001] This invention relates to the field of welding fixture technology, and in particular to a quick clamping device for welding vertical plates at 90 degrees. Background Technology

[0002] In the aerospace field, due to the large dimensions of aerospace parts made of composite materials, the support frame for these formed parts typically consists of a "well"-shaped inner plate and a "mouth"-shaped outer plate. Since each vertical plate forming the "well"-shaped inner plate has milled slots that allow for 90-degree insertion, the assembly process involves simply welding the outer "mouth"-shaped outer plate (composed of four vertical plates) and then placing the assembled "well"-shaped inner plate inside. During the welding and fabrication of the "mouth"-shaped outer plate, the joining dimensions and angles of the four vertical plates are crucial—the corners of the four outer vertical plates must be right angles, the plates must be perpendicular, and the welding thickness deformation must be less than 5mm.

[0003] Currently, since the welding of the profile support frame needs to be completed on a rectangular horizontal workbench, when welding the "U" shaped outer plate, the upright plate needs to be placed vertically on the horizontal workbench and welded close to the adjacent upright plate at a 90-degree angle.

[0004] However, since the vertical plates are typically fixed to the horizontal workbench by installing horizontal pressure plates above them, and it is also necessary to check the angles of each plate to be welded and the fit between adjacent plates, and adjust the angles of each plate by loosening the pressure plates, the preparation work before welding is very tedious and time-consuming. Summary of the Invention

[0005] The purpose of this invention is to provide a quick clamping device for welding vertical plates at 90 degrees. This device can easily adjust the angle of the vertical plates, thereby improving the efficiency of welding vertical plates at 90 degrees.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is: a quick clamping device for 90-degree welding of vertical plates, including a base plate, a clamping plate mounting seat is provided on one side of the upper surface of the base plate, and a positioning tube is detachably installed on the other side. A vertically arranged rotating clamping plate that can swing to a 90-degree vertical state towards the positioning tube is hinged to the side of the clamping plate mounting seat near the positioning tube. A wedge-shaped pressure block is detachably inserted vertically between the positioning tube and the rotating clamping plate.

[0007] As a further improvement of the present invention, a spring-loaded pin is provided between the rotating clamping plate and the clamping plate mounting base. One end of the spring-loaded pin is fixed to the clamping plate mounting base, and the other end is elastically contacted with the rotating clamping plate.

[0008] As a further improvement of the present invention, a mounting boss is provided on the upper surface of the base plate, and the lower end of the positioning tube is detachably sleeved on the outside of the mounting boss.

[0009] As a further improvement of the present invention, the clamp mounting base is also provided with a mounting boss, and the lower surface of the base plate below the two mounting bosses is provided with a magnet groove, and a magnet is embedded in the magnet groove.

[0010] As a further improvement of the present invention, the magnet is fixedly installed in the magnet slot by a fastening screw, the screw end of which passes through the magnet and is threadedly connected to the mounting boss.

[0011] As a further improvement of the present invention, the top of the clamp mounting base is provided with a hinge portion, and a hinge shaft is horizontally mounted on the hinge portion. Both ends of the hinge shaft are hinged to the hinge ears on the rotating clamp.

[0012] As a further improvement of the present invention, a support block is provided on the lower edge of the rotating clamp on the side facing the positioning tube.

[0013] As a further improvement of the present invention, the positioning tube is provided with a positioning inclined surface on the side facing the rotating clamp.

[0014] As a further improvement of the present invention, a guide pin is provided on the positioning inclined surface, and a guide groove is provided on the side wall of the wedge-shaped pressure block that contacts the positioning inclined surface, which engages with the guide pin and extends along the insertion direction of the wedge-shaped pressure block.

[0015] As a further improvement of the present invention, a pulling rod is vertically connected to the top of the wedge-shaped pressure block, and a handle ring is connected to the upper end of the pulling rod.

[0016] Beneficial effects

[0017] Compared with the prior art, the advantages of the quick clamping device for 90-degree vertical plate welding of the present invention are as follows: 1. After the device is installed on the horizontal workbench, the operator only needs to first insert the vertical plate vertically between the rotating clamp and the positioning tube, and then insert the wedge-shaped pressure block between the vertical plate and the positioning tube. With the insertion of the wedge-shaped pressure block, the vertical plate can be made 90 degrees perpendicular to the horizontal workbench, thereby improving the clamping and fixing efficiency of the vertical plate perpendicular to the horizontal workbench, without the need for additional repeated adjustments to the vertical plate. Regarding the right-angle splicing of two adjacent upright plates, it is only necessary to clamp and fix each upright plate with two of these devices placed at intervals, and to ensure that the distance between the two devices and the edge of the horizontal worktable is the same. This will make the upright plate vertical and consistent with the edge distance of the horizontal worktable. Afterwards, the remaining upright plates are clamped and fixed in the same way to achieve the same distance between the upright plates and the edge distance of the horizontal worktable. This will enable the requirement that two adjacent outer upright plates be placed at a 90-degree angle. Therefore, with this device, the operator can easily complete the assembly of the upright plate before welding the "U"-shaped outer plate, avoiding the tedious process of angle adjustment required by the traditional pressure plate clamping upright plate, and improving work efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0024] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0025] Example

[0026] Specific embodiments of the present invention are as follows: Figure 1-3 As shown, a quick clamping device for 90-degree welding of vertical plates includes a horizontally arranged rectangular base plate 1. A clamping plate mounting seat 2 is vertically arranged on one side of the upper surface of the base plate 1, and a positioning tube 5 is detachably and vertically mounted on the other side. A vertically arranged rotating clamping plate 3, capable of swinging to a 90-degree vertical position towards the positioning tube 5, is hinged to the clamping plate mounting seat 2 near the positioning tube 5. A wedge-shaped pressure block 6 is detachably inserted vertically between the positioning tube 5 and the rotating clamping plate 3. Furthermore, to ensure the rotating clamping plate 3 remains tilted in its initial state and resets after use, a spring-loaded pin 4 is also provided between the rotating clamping plate 3 and the clamping plate mounting seat 2 in this embodiment. One end of the spring-loaded pin 4 is fixed to the clamping plate mounting seat 2, and the other end is elastically in contact with the rotating clamping plate 3.

[0027] When using this device to vertically fix each upright plate onto a horizontal workbench, the device must first be installed on the workbench, and two of these devices are required for clamping and fixing each upright plate. Specifically, the operator simply inserts the upright plate vertically between the rotating clamp 3 and the positioning tube 5, and then inserts the wedge-shaped pressure block 6 between the upright plate and the positioning tube 5. With the insertion of the wedge-shaped pressure block 6, the upright plate is made 90 degrees perpendicular to the horizontal workbench, thus improving the clamping efficiency of the upright plate perpendicular to the horizontal workbench without the need for repeated adjustments.

[0028] Regarding the right-angle splicing of two adjacent upright plates, simply place the two devices that clamp each upright plate at intervals, and ensure that the distance between the base plate 1 of the two devices and the edge of the horizontal worktable is the same. This will make the upright plate vertical and align with the edge of the horizontal worktable. Subsequently, the remaining upright plates will also be fixed and clamped in this manner to achieve the same vertical distance as the edge of the horizontal worktable, thus fulfilling the requirement that two adjacent outer upright plates be placed at a 90-degree angle.

[0029] Therefore, with this device, the operator can easily complete the assembly of the upright plate before welding the "U"-shaped outer plate, avoiding the tedious process of angle adjustment required by the traditional pressure plate clamping upright plate, thereby improving work efficiency.

[0030] For the installation of the positioning tube 5, a mounting boss 11 is provided on the upper surface of the base plate 1, and the lower end of the positioning tube 5 is detachably sleeved on the outside of the mounting boss 11. Through this positioning tube 5, the operator can easily complete the installation and removal of the positioning tube 5.

[0031] Meanwhile, to facilitate quick assembly and disassembly of the device on a horizontal workbench, the clamp mounting base 2 of the device is also provided with a mounting boss 11, and the lower surface of the base plate 1 below both mounting bosses 11 is provided with a magnet groove 12, in which a magnet 7 is embedded. In this embodiment, the magnet 7 is fixedly installed in the magnet groove 12 by a fastening screw 13, the screw end of the fastening screw 13 passing through the magnet 7 and threadedly connected to the mounting boss 11. Using this magnet 7, the device can be magnetically attached to the horizontal workbench, facilitating assembly and disassembly while allowing the device's position to be adjusted by pushing and pulling.

[0032] Regarding the hinge connection between the rotating clamping plate 3 and the clamping plate mounting base 2, the top of the clamping plate mounting base 2 of this device is provided with a hinge part 22, and a hinge shaft 21 is horizontally mounted on the hinge part 22. Both ends of the hinge shaft 21 are hinged to the hinge ears 32 on the rotating clamping plate 3. This design enables the hinged installation of the rotating clamping plate 3 and the clamping plate mounting base 2. At the same time, a support block 31 is provided on the lower edge of the rotating clamping plate 3 facing the positioning tube 5. The support block 31 can hold the lower edge of the upright plate and prevent it from sliding down and falling off.

[0033] Furthermore, a positioning inclined surface 51 is provided on the side of the positioning tube 5 facing the rotating clamping plate 3. A guide pin 52 is provided on the positioning inclined surface 51. A guide groove 61 is provided on the side wall of the wedge-shaped pressure block 6 that contacts the positioning inclined surface 51, and extends along the insertion direction of the wedge-shaped pressure block 6. In this embodiment, the guide groove 61 is a T-shaped groove and its lower end extends to the lower end of the wedge-shaped pressure block 6. Through the positioning and guiding cooperation between the guide pin 52 and the guide groove 61, the insertion path of the wedge-shaped pressure block 6 can be accurately guided, thereby accurately achieving a 90-degree perpendicularity between the upright plate and the horizontal worktable.

[0034] In addition, to facilitate the operator to insert and remove the wedge-shaped pressure block 6, a pulling rod 62 is vertically connected to the top of the wedge-shaped pressure block 6, and a handle ring 63 is connected to the upper end of the pulling rod 62.

[0035] The specific usage process of this device is as follows: First, place two or three of these devices at equal intervals from the edge of the horizontal worktable, ensuring the clamped vertical plate is parallel to the edge of the horizontal worktable. Then, place the vertical plate on the support block 31 of the inclined rotating clamping plate 3, which is supported by the spring-loaded pin 4. At this time, the positioning tube 5 with its bottom opening and the spring-loaded pin 4 can control the inclination of the inclined rotating clamping plate 3.

[0036] Screw the lifting rod 62 into the threaded hole on the top surface of the wedge-shaped pressure block 6, engage the guide groove 61 of the wedge-shaped pressure block 6 with the guide pin 5 and move it downward. The downward movement of the wedge-shaped pressure block 6 will abut against the upright plate and the rotating clamping plate 3, causing the upright plate supported by the support block 31 of the rotating clamping plate 3 and the rotating clamping plate 3 to rotate around the hinge axis 21 to a vertical state. At this time, the stroke of the spring pin 4 is compressed.

[0037] After the first upright plate is rotated to a vertical position, similarly, the other upright plate is rotated to a vertical position and brought closer to the adjacent upright plate. Because the bottom surface of the base plate 1 has magnets 7 installed by fastening screws 13, the magnetic force of the magnets 7 can attract the device to the horizontal workbench surface without it tipping over. Furthermore, since the magnetic force is vertical, it is relatively easy to move the clamp by hand. Afterwards, it is only necessary to check that the distance between the device supporting the two upright plates and the edge of the horizontal workbench or the groove is consistent, so that the splicing angle between adjacent upright plates is 90 degrees and the vertical height is consistent. This satisfies the splicing condition before welding. Similarly, all four outer upright plates can be spliced ​​together.

[0038] After the outer "U"-shaped plate composed of the four outer vertical plates is welded, before the assembled "well"-shaped inner plate is placed inside the outer "U"-shaped plate, if it is necessary to move or remove this device, the lifting rod 62 can be used to pull up the wedge-shaped pressure block 6 along the positioning slope 51 of the positioning tube 5 with the bottom opening. After the guide groove 61 of the wedge-shaped pressure block 6 is disengaged from the guide pin 52, the positioning tube 5 with the bottom opening can be removed, and the device can be moved horizontally out of the outer "U"-shaped plate by hand. At this time, the 90-degree welded vertical plate quick positioning clamping device is completed.

[0039] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
