Description

Technical Field

[0001] This application relates to the technical field of hinge installation, and in particular to a positioning fixture for installing hinges on irregularly shaped plates. Background Technology

[0002] A hinge is a mechanical device used to connect two solid objects and allow relative rotation between them. Hinges can consist of movable components or be made of foldable materials. Hinges are most commonly installed on cabinets and are mainly classified by material into stainless steel hinges and iron hinges. To provide a better user experience, hydraulic hinges have also emerged, characterized by a cushioning function when the cabinet door closes, minimizing the noise generated by the door colliding with the cabinet body.

[0003] Currently, when installing hinges between two panels, both panels must first be laid flat before the hinge is installed in the appropriate position between them. To ensure the panels can rotate normally without interfering with each other, a certain distance must be maintained between the two panels during hinge installation, depending on the hinge specifications, and the rotating sides of the two panels must remain parallel. Measuring the distance after placing the two panels will affect the installation efficiency. Furthermore, manual measurement of the distance between the panels will introduce measurement errors, leading to reduced hinge installation accuracy. Utility Model Content

[0004] To improve the efficiency and accuracy of hinge installation, this application provides a positioning fixture for installing hinges on irregularly shaped panels.

[0005] The positioning fixture for installing irregularly shaped plate hinges provided in this application adopts the following technical solution:

[0006] A positioning fixture for installing an irregularly shaped plate hinge includes a placement frame and a positioning assembly. The placement frame includes two parallel first placement rods and two second placement rods parallel to each other between the two first placement rods. The positioning assembly includes a partition plate and an intermediate plate assembly. The intermediate plate assembly is connected to the placement frame and is arranged parallel to the second placement rods. Several partition plates are vertically arranged on the top surface of the intermediate plate assembly along its length, and the partition plates are located on the same straight line.

[0007] By adopting the above technical solution, before installing the hinge, two irregularly shaped plates are placed on the placement frame, with the two sides of the partition plate respectively abutting the rotating sides of the two irregularly shaped plates, maintaining a fixed distance between them. The hinge is then installed between the two irregularly shaped plates, achieving precise hinge installation. Through the cooperation of the placement frame and positioning components, precise spacing and positioning of the irregularly shaped plates are achieved, improving the efficiency and accuracy of sheet metal hinge installation.

[0008] Optionally, an abutment block is provided on the top surface of one of the first placement plates, and the abutment block is located on the extension line of the partition plate.

[0009] By adopting the above technical solution, the abutment block limits one end of the two irregular plates. The abutment block and the partition plate work together to achieve precise positioning of the two irregular plates.

[0010] Optionally, the intermediate plate assembly includes a fixed plate and a sliding plate. The fixed plate is fixedly connected to the placement frame, and the sliding plate is slidably connected to the placement frame. A plurality of plug-in blocks are provided on the side of the sliding plate near the fixed plate, and a plurality of plug-in slots are provided on the side of the fixed plate near the sliding plate. The plurality of plug-in blocks and the plurality of plug-in slots correspond one-to-one and are plugged in. A plurality of partition plates are provided on both the fixed plate and the sliding plate. When the plug-in block abuts against the inner bottom wall of the plug-in slot, the plurality of partition plates are located on the same straight line. The placement frame is provided with a driving member for driving the sliding plate to move in a direction closer to or away from the fixed plate.

[0011] By adopting the above technical solution, several partition plates are provided on both the fixed plate and the sliding plate. For different hinge specifications, the distance between the rotating sides of the two irregularly shaped plates needs to be adjusted appropriately. At this point, a driving component is used to adjust the distance between the fixed plate and the sliding plate, thereby achieving the adjustment of the distance between the two rows of partition plates and expanding the applicability of the device.

[0012] Optionally, the driving component includes an adjusting screw, an adjusting guide rod, and a mounting rod. Two mounting rods are connected in parallel between the two first placement rods. The mounting rods are arranged parallel to the sliding plate and are located on both sides of the intermediate plate assembly. The adjusting screw and the adjusting guide rod are arranged between the two mounting rods and are parallel to the first placement rods. The adjusting screw is rotatably connected to the mounting rods. The adjusting screw is threadedly connected to the sliding plate and passes through the fixed plate. The adjusting guide rod passes through the fixed plate and the sliding plate and is slidably connected to them. The mounting rod is provided with a driving source for driving the adjusting screw to rotate.

[0013] By adopting the above technical solution, when it is necessary to drive the sliding plate to move, the drive source drives the adjusting screw to rotate. Under the driving and guiding action of the adjusting screw and the adjusting guide rod, the sliding plate slides away from the fixed plate. The fixed plate and the two rows of partition plates on the sliding plate gradually move away from each other, thereby realizing the adjustment of the side spacing of the irregular plate.

[0014] Optionally, the adjusting guide rod is provided with an adjusting scale line along its length.

[0015] By adopting the above technical solution, the setting of the adjustable scale line facilitates the operator's precise observation of the spacing between the two rows of partition plates on the fixed plate and the sliding plate.

[0016] Optionally, each of the second placement rods is provided with an extension rod at one end. Both the second placement rod and the extension rod are provided with a set of pressing members. The pressing members include a mounting block, a mounting plate, a rotating rod, and a rotating handle. The mounting block is disposed on the corresponding second placement rod and the extension rod. The mounting plate is vertically disposed on the top surface of the mounting block. The rotating rod is rotatably disposed on the mounting plate. The rotating handle is disposed at one end of the rotating rod.

[0017] By adopting the above technical solution, when the irregularly shaped plate is placed in a suitable position on the placement frame and the corresponding rotating handle is rotated, the end of the rotating rod presses the irregularly shaped plate firmly onto the placement frame, reducing the possibility of the irregularly shaped plate shaking on the placement frame during the installation of the hinge.

[0018] Optionally, the end of the rotating rod away from the rotating handle is provided with an installation port, a connecting rod is provided in the installation port, and a rubber block is provided at the bottom end of the connecting rod.

[0019] By adopting the above technical solution, the setting of the abutting rubber block avoids direct contact between the rotating rod and the surface of the irregular plate, reducing the possibility of damage to the surface of the irregular plate during the positioning process.

[0020] Optionally, the top surfaces of the second placement rod and the extension rod are provided with sliding T-slots along their length direction, and the bottom surface of the mounting block is provided with a sliding T-block. The sliding T-block is slidably disposed in the corresponding sliding T-slot, and the mounting block is provided with a positioning element for positioning it.

[0021] By adopting the above technical solution, the sliding T-block and sliding T-slot are set to realize the sliding connection between the mounting block and the placement frame. For irregularly shaped plates of different shapes, the specific position of the mounting block on the placement frame is adjusted, and the mounting block is positioned by the positioning component, so that the device can be applied to irregularly shaped plates of different shapes.

[0022] Optionally, a mounting base plate is provided parallel to the bottom of the placement frame, and a plurality of lifting cylinders are provided on the top surface of the mounting base plate. The output shaft of the lifting cylinders is connected to the placement frame in a transmission manner. A plurality of top support rods are vertically provided on the top surface of the mounting base plate, and the top end of the top support rods is provided with abutment rollers.

[0023] By adopting the above technical solution, after the hinge is installed, the lifting cylinder drives the placement frame to descend and makes the irregular plate abut against the abutting roller, which makes it convenient for the operator to move the irregular plate out of the top of the placement frame.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. Through the cooperation of the placement frame and positioning components, precise interval positioning of irregularly shaped panels is achieved, which improves the efficiency and accuracy of panel hinge installation.

[0026] 2. The setting of the abutting rubber block avoids direct contact between the rotating rod and the surface of the irregular plate, reducing the possibility of damage to the surface of the irregular plate during the positioning process;

[0027] 3. The setting of the fixed plate and the sliding plate enables the adjustment of the spacing between the two rows of partition plates, thus expanding the applicability of the device. Attached Figure Description

The plurality of insertion slots 7 correspond one-to-one with the plurality of insertion blocks 6 and are slidably connected. Several partition plates 22 are vertically arranged on the top surface of the fixed plate 27 and the sliding plate 28. When the plug block 6 abuts against the inner bottom wall of the plug groove 7, several partition plates 22 on the fixed plate 27 and the sliding plate 28 are located on the same straight line. The thickness of the partition plate 22 used in this embodiment is 1mm.

[0036] Reference Figure 3 Two mounting rods 26 are connected parallel to each other between the two first placement rods 101. The mounting rods 26 are parallel to the fixing plate 27 and are respectively located on opposite sides of the intermediate plate assembly. The two ends of the adjusting screw 24 are rotatably connected between the two mounting rods 26. The adjusting motor 23 is connected to one of the mounting rods 26, and the output shaft of the adjusting motor 23 is drivenly connected to one end of the adjusting screw 24. The adjusting screw 24 is threadedly connected to the sliding plate 28 and passes through the fixing plate 27. The adjusting guide rod 25 is fixedly connected between the two mounting rods 26 and is parallel to the adjusting screw 24. The adjusting guide rod 25 passes through the fixing plate 27 and the sliding plate 28 and is slidably connected to both. The adjusting guide rod 25 has an adjustment scale line 8 along its length.

[0037] Reference Figure 2 and Figure 4Each second placement rod 102 and each extension rod 5 is equipped with a set of pressing components, including a mounting block 9, a sliding T-block 10, a mounting plate 11, a rotating rod 12, a rotating handle 13, a connecting rod 14, a connecting nut 15, and an abutting rubber block 16. Sliding T-slots 103 are provided along the length of the top surface of both the second placement rod 102 and the extension rod 5. The sliding T-block 10 is fixedly connected to the bottom surface of the mounting block 9 and slides within the sliding T-slot 103. A connecting bolt is vertically threaded onto the mounting block 9, with the bottom end of the connecting bolt abutting against the top surface of the corresponding second placement rod 102 or extension rod 5 to position the mounting block 9.

[0038] Reference Figure 1 and Figure 4 The mounting plate 11 is vertically fixed to the top surface of the mounting block 9. The middle position of the rotating rod 12 is rotatably connected to the mounting plate 11. The rotating handle 13 is connected to one end of the rotating rod 12. The end of the rotating rod 12 away from the rotating handle 13 is provided with a mounting port 17. The connecting rod 14 is set in the mounting port 17. The abutting rubber block 16 is connected to the bottom end of the connecting rod 14. The connecting nut 15 is threadedly connected to the end of the connecting rod 14 away from the abutting rubber block 16 and abuts against the rotating rod 12. The top surface of the first placement rod 101 away from the extension rod 5 is provided with an abutting block 21. Several top support rods 19 are vertically connected to the top surface of the mounting base plate 3. The top end of each top support rod 19 is provided with an abutting roller 18.

[0039] Reference Figure 1 , Figure 2 and Figure 4 When installing hinges on irregularly shaped plates, place two plates on the placement frame 1, ensuring their rotating sides abut against the partition plate 22 and one end abuts against the abutment block 21. The abutment block 21 and several partition plates 22 ensure accurate positioning of the two plates and maintain a fixed 1mm distance between their rotating sides, facilitating subsequent hinge installation. After placing the plates, rotate the handle 13 to press the abutment rubber block 16 at the end of the rotating rod 12 against the placement frame 1, thus positioning the plates and reducing the possibility of them wobbling on the placement frame 1 during hinge installation. After placing and positioning the plates, place the hinge at a specific position between the two plates and connect it to the plates using a connector.

[0040] Reference Figure 2 and Figure 3To accommodate the different hinge specifications, the spacing between the two irregularly shaped plates needs to be adjusted appropriately. The adjusting motor 23 starts and drives the adjusting screw 24 to rotate. Under the driving and guiding action of the adjusting screw 24 and the adjusting guide rod 25, the sliding plate 28 moves away from the fixed plate 27. The operator can precisely adjust the position of the sliding plate 28 and the spacing between the two rows of partition plates 22 according to the adjusting scale line 8 on the adjusting guide rod 25.

[0041] Reference Figure 1 and Figure 4 After the hinge installation is completed, the output shaft of the lifting cylinder 4 shortens, the placement frame 1 descends, and the irregularly shaped plate placed on the top surface of the placement frame 1 contacts the abutment roller 18 at the top of the top support rod 19, making it convenient for the operator to slide the irregularly shaped plate out of the placement frame 1. After the material is unloaded, the output shaft of the lifting cylinder 4 extends, and the placement frame 1 rises accordingly, facilitating the next round of irregularly shaped plate hinge installation. For irregularly shaped plates of different shapes, the position of the pressing member on the second placement rod 102 and the extension rod 5 can be adjusted, and the position of the mounting block 9 can be locked using connecting bolts.

[0042] The implementation principle of a positioning fixture for installing hinges on irregularly shaped plates in this embodiment is as follows: When installing hinges on irregularly shaped plates, two irregularly shaped plates are placed on the placement frame 1, with their rotating sides abutting against the partition plate 22 and one end abutting against the abutting block 21. The abutting block 21 and several partition plates 22 are used to accurately position the two irregularly shaped plates. Rotating the rotating handle 13 positions the irregularly shaped plates. After placing and positioning the irregularly shaped plates, the hinge is placed at a specific position between the two plates, and a connector is used to connect the hinge to the irregularly shaped plates.

[0043] After the hinge is installed, the placement frame 1 is lowered, and the irregular plate placed on the top surface of the placement frame 1 contacts the abutting roller 18 at the top of the top support rod 19, which makes it convenient for the operator to slide the irregular plate out of the top of the placement frame 1.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
