Technical Field

[0001] The present application relates to the field of sheet metal riveting, and more specifically, to a fixing structure and a sheet metal riveting device. Background Art

[0002] Riveting is a process used to connect two parts. Under the action of external pressure, the body material undergoes plastic deformation to achieve reliable connection between parts. Riveting is applicable to a variety of materials, such as ordinary low-carbon steel, aluminum alloy plates, copper plates, etc. However, for stainless steel and high-carbon steel plates, due to their relatively hard materials, special high-strength riveting parts are required.

[0003] During the process of riveting on a steel plate, the end of a bolt needs to be riveted to the steel plate by pressing. Currently, a number of equally spaced riveting holes are provided on the existing steel plate for riveting a number of bolts. However, the existing riveting method is to manually move the steel plate by hand, align the riveting holes on the steel plate with the bottom die holder, then pass the bolt through the riveting hole, and use a pressing device to squeeze the end of the bolt to complete the riveting process. The method of holding the steel plate by hand will reduce the stability of the steel plate and will affect the riveting process of the bolt to a certain extent. For this reason, we propose a fixing structure and a sheet metal riveting device. Summary of the Utility Model

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present application will be described in conjunction with the accompanying drawings in the embodiments of the present application.

[0026] Please refer to Figures 1-8 , the present application provides a fixing structure, including a table body 10, a working groove 20 is opened at the top of the table body 10, a sliding groove 30 is opened on the side wall of the working groove 20, a plurality of positioning holes 40 are opened at equal intervals on the side wall of the sliding groove 30, and a positioning component 50 is slidably connected therein. The positioning component 50 is switched between a plurality of positioning holes 40, and a steel plate clamping member 60 is installed on one end side wall thereof. Specifically, the positioning component 50 slides in the sliding groove 30, so that the positioning component 50 can switch positions between a plurality of positioning holes 40, so as to achieve the purpose that the single moving distance of the positioning component 50 is the same. The distance between two adjacent positioning holes 40 is the same as the distance between two adjacent riveting holes on the steel plate. Thus, the steel plate is clamped and fixed by the steel plate clamping member 60, and the steel plate clamping member 60 is pushed to move, so that the moving distance each time is the same, which is convenient for moving the riveting vacancies on the steel plate. At the same time, the cooperation between the positioning component 50 and the positioning holes 40 can improve the stability of the steel plate.

[0027] Refer toFigure 3 and 8 The positioning assembly 50 includes a slider 510 slidably disposed in the chute 30. One end of the slider 510 is fixedly connected to the steel plate clamping member 60, and an installation groove 520 is formed on the side wall of the other end thereof. A positioning block 530 is slidably disposed in the installation groove 520. A spring 540 is connected between the positioning block 530 and the installation groove 520. The cross sections of the installation groove 520 and the positioning block 530 are both T-shaped. When setting, one end of the positioning block 530 is stuck in the positioning hole 40 to achieve the positioning purpose of the positioning block 530, thereby achieving the positioning purpose of the steel plate clamping member 60. When the spring 540 is compressed, an elastic force can be provided to the positioning block 530, so that through the cooperation between the positioning block 530 and the positioning hole 40, the stability of the steel plate can be improved. Further, the cross sections of the installation groove 520 and the positioning block 530 are T-shaped to achieve the purpose of limiting the positioning block 530.

[0028] Refer to Figure 8 , one end of the positioning block 530 and several positioning holes 40 are both arc-shaped. The arc surface of the positioning block 530 is attached to one of the positioning holes 40. When specifically setting, one end of the positioning block 530 and the positioning holes 40 are both arc-shaped, which can achieve that when pushing the steel plate clamping member 60, the slider 510 drives the positioning block 530 to move, and the arc surface of the positioning block 530 will be squeezed by the arc surface of the positioning hole 40, so that the positioning block 530 slides into the installation groove 520, and the positioning block 530 can be made to move out of the positioning hole 40.

[0029] Refer to Figure 7 , a limiting block 310 is fixedly installed on the inner wall of the chute 30, and a limiting groove 550 is formed on the slider 510. The limiting groove 550 is sleeved on the limiting block 310. It should be noted that the limiting block 310 can limit the slider 510 and prevent it from falling off the chute 30.

[0030] Refer to Figures 1-3 , the steel plate clamping member 60 includes a U-shaped plate 610 fixedly connected to the side wall of one end of the slider 510. A screw rod 620 is threadedly penetrated through the top of the U-shaped plate 610. The bottom of the screw rod 620 is rotatably connected to a pressing plate 630 for fixing the steel plate. Specifically, a limiting rod is fixedly installed on the top of the pressing plate 630, and the limiting rod slidably penetrates through the top of the U-shaped plate 610 to further achieve the purpose of limiting the pressing plate 630. Then, the steel plate is placed at the bottom of the U-shaped plate 610, and by rotating the screw rod 620, the pressing plate 630 moves downward to fix the steel plate.

[0031] Refer to Figures 1-8 , a sheet metal press riveting device includes

[0032] The above-mentioned fixing structure; and the riveting mechanism 70 and the lower die base 80. The riveting mechanism 70 is installed on the table body 10, and the lower die base 80 is installed on the working groove 20. The lower die base 80 includes a cylindrical seat 810. A circular hole 820 is opened at the top of the cylindrical seat 810. An opening 830 is opened on the side wall of the circular hole 820. Support grooves 840 are opened on the side walls at both ends of the opening 830. A support block 850 is rotatably connected to one of the support grooves 840. The other end of the support block 850 is placed on the other support groove 840. When specifically set, in order to further facilitate the horizontal movement of the steel plate, an opening 830 is opened at one end of the cylindrical seat 810. After placing the steel plate on the cylindrical seat 810, the riveting hole on the steel plate is made to correspond to the circular hole 820 on the cylindrical seat 810. The bolt is inserted into the circular hole 820 through the hole on the steel plate, and the end of the bolt head is placed on the steel plate, so that the riveting mechanism 70 presses down the end of the bolt to achieve the riveting purpose. After the riveting is completed, the U-shaped plate 610 can be horizontally pushed to move, so as to drive the steel plate to move horizontally. At the same time, the bolt exits the circular hole 820 from the opening 830 on one side of the circular hole 820, realizing the convenient horizontal movement of the steel plate. The support block 850 can rotate to the support groove 840, so that the steel plate can be supported in cooperation with the cylindrical seat 810 during riveting.

[0033] When the present fixing structure and sheet metal riveting device are in use: One end of the steel plate is placed at the bottom of the U-shaped plate 610, and at the same time the steel plate is placed on the cylindrical seat 810. Then, the first riveting hole on the steel plate is adjusted to correspond to the circular hole 820. After that, the screw 620 can be rotated to make the pressing plate 630 move downward to fix the steel plate. Then, the bolt is inserted into the circular hole 820 through the hole on the steel plate. At the same time, one end of the support block 850 is pushed to move into the corresponding support groove 840. Then, the riveting mechanism 70 can be started to make the riveting mechanism 70 press down the end of the bolt to achieve the riveting purpose. After the riveting is completed, the riveting mechanism 70 resets, and the U-shaped plate 610 is horizontally pushed to move, so that the positioning block 530 moves into the next positioning hole 40. At this time, the hole on the steel plate will correspond to the circular hole 820. The bolt is inserted into the circular hole 820 through the hole, and one end of the support block 850 is pushed into the support groove 840, and then the riveting operation can be carried out again. After that, the above operations are repeated.

[0034] It should be noted that the specific model and specification of the riveting mechanism 70 need to be selected and determined according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in the field, so it will not be elaborated in detail.

[0035] The power supply and principle of the riveting mechanism 70 are clear to those skilled in the art and will not be described in detail here.
