[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 , Figure 2 and Figure 5 One embodiment provided by this utility model:

[0028] A heat-riveting fixture that is easy to assemble and disassemble includes a base plate 5, with columns 4 fixedly installed at the four corners of the upper surface of the base plate 5, a top plate 2 fixedly installed at the upper end of the four columns 4, and movable plates 3 slidably installed on the surface of the four columns 4.

[0029] The base plate 5 and the movable plate 3 are both fixedly provided with fixing mechanisms 8 on opposite sides. The upper side of the two fixing mechanisms 8 is provided with an upper fixture mechanism 9, and the lower side of the two fixing mechanisms 8 is provided with a lower fixture mechanism 10.

[0030] Specifically, the base plate 5, column 4, and top plate 2 provide support for the overall use of the device, ensuring its effectiveness. The movable plate 3 facilitates the downward hot riveting function of the device. The fixing mechanism 8 secures the upper fixture mechanism 9 and the lower fixture mechanism 10 during use. The upper fixture mechanism 9 and the lower fixture mechanism 10 enable the device to function as a basic hot riveting fixture.

[0031] A hydraulic cylinder 1 is fixedly installed at the upper end of the top plate 2. The output end of the hydraulic cylinder 1 passes through the top plate 2 and is fixedly connected to the middle position of the upper surface of the movable plate 3.

[0032] Specifically, by setting up a hydraulic cylinder 1, when in use, the hydraulic cylinder 1 is connected to the movable plate 3 and the hydraulic cylinder 1 is connected to the hydraulic equipment. The hydraulic cylinder 1 can pressurize the upper fixture mechanism 9 to realize the pressurized hot riveting function when the device is in use. The use of the hydraulic cylinder 1 connected to the hydraulic equipment is an existing mature technology, and its specific principle will not be elaborated in the application.

[0033] A support box 6 is fixedly installed below the base plate 5. Two storage boxes 7 are slidably installed inside the support box 6. Multiple locking blocks 11 are fixedly installed inside each of the two storage boxes 7. Multiple filler pieces 12 are locked between the multiple locking blocks 11.

[0034] Specifically, the device is equipped with a support box 6, which allows users to place the entire device in a suitable position for use. The storage box 7 allows users to store the filler 12 during use. The locking block 11 allows the filler 12 to be locked in place. With the filler 12, when users need to adjust the quantity of the upper fixture mechanism 9 and the lower fixture mechanism 10, and the fixing mechanism 8 cannot be filled completely, the users can install the filler 12 into the empty space of the fixing mechanism 8, thus realizing the quantity adjustment function of the device during use.

[0035] Reference Figure 3 , Figure 4 The fixing mechanism 8 includes a mounting groove 802, with protective plates 801 fixedly installed on both sides of the mounting groove 802, and fixing blocks 803 fixedly installed at both ends of the mounting groove 802 by bolts.

[0036] Specifically, by providing the mounting slot 802, the user can select an appropriate number of upper fixture mechanisms 9 and lower fixture mechanisms 10 according to the size and quantity of the circuit boards to be hot-riveted, and slide them into the mounting slot 802 through the upper connecting block 901 and the lower connecting block 1003. If there are empty spaces, they are filled by the filler 12. The fixing block 803 is fixed to both sides of the mounting slot 802 by bolts, and the upper fixture mechanism 9 and lower fixture mechanism 10 are installed. By providing the protective plate 801, the upper fixture mechanism 9 and lower fixture mechanism 10 can be protected on both sides during use to ensure their stability during use.

[0037] The upper fixture mechanism 9 includes an upper fixture body 902, an upper connecting block 901 fixedly installed at the upper end of the upper fixture body 902, and multiple hot riveting heads 903 fixedly installed on the bottom surface of the upper fixture body 902.

[0038] Specifically, by setting up an upper fixture body 902 and combining it with a hot riveting head 903 on its surface, when in use, the hot riveting head 903 is connected to a heating device, which can realize the hot riveting function when the device is in use. The hot riveting head 903 is an existing mature technology, so its specific principle is not described in the application. By setting up an upper connecting block 901, it is convenient for the user to install the upper fixture mechanism 9 onto the fixing mechanism 8 for use.

[0039] The lower fixture mechanism 10 includes a lower fixture body 1002, a fixed frame 1001 fixedly disposed on the upper surface of the lower fixture body 1002, and a lower connecting block 1003 fixedly disposed on the bottom surface of the lower fixture body 1002.

[0040] Specifically, by providing a lower fixture body 1002 and a fixing frame 1001 on its upper surface, the fixing frame 1001 can fix the circuit board to be processed when the user uses it. By providing a lower connecting block 1003, the lower connecting block 1003 can be inserted into the mounting slot 802 of the fixing mechanism 8 when in use, thereby fixing the lower fixture body 1002.

[0041] Working Principle: When using this device, select the appropriate number of upper fixture mechanisms 9 and lower fixture mechanisms 10 according to the shape and quantity of the workpiece to be hot-riveted. Slide the upper fixture mechanism 9 into the mounting groove 802 of the fixing mechanism 8 on the base plate 5 and movable plate 3 via the upper connecting block 901. Slide the lower fixture mechanism 10 into the mounting groove 802 of the fixing mechanism 8 via the lower connecting block 1003. Use bolts to fix the fixing blocks 803 to both ends of the mounting groove 802, ensuring that the upper fixture mechanism 9 and lower fixture mechanism 10 are firmly installed. If there are empty spaces in the mounting groove 802, filler parts 12 can be used to snap between the clips 11 to fill the empty spaces and maintain the stability of the fixing mechanism 8. During hot riveting, place the workpiece to be hot-riveted... In the fixed frame 1001 of the lower fixture mechanism 10, the hydraulic cylinder 1 is activated. The output end of the hydraulic cylinder 1 pushes the movable plate 3 downward, causing the upper fixture mechanism 9 to press downward. The hot riveting head 903 of the upper fixture mechanism 9 contacts the workpiece and heats it. At the same time, the hydraulic cylinder 1 applies pressure to complete the hot riveting operation. After the hot riveting is completed, the hydraulic cylinder 1 retracts and the movable plate 3 returns to its initial position. If it is necessary to change the fixture or adjust the quantity, loosen the bolts on the fixing block 803 and slide the upper fixture mechanism 9 and the lower fixture mechanism 10 out of the mounting slot 802. Select and install the fixture again according to the new requirements and repeat the above installation steps. The disassembled fixture and filler 12 can be stored in the storage box 7 in the support box 6 for easy use later.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
