[0019] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0020] Example

[0021] Please see Figures 1-5 This utility model discloses a riveting device for sheet metal processing, comprising a processing table 1, a vertical plate 2, a fixed frame 10, and a positioning table 11. The vertical plate 2 is fixedly connected to the rear end of the processing table 1. A transverse cylinder 3 is fixedly installed at the upper rear end of the vertical plate 2. A connecting frame 4 is fixedly connected to the upper front end of the vertical plate 2. Two sets of guide columns 5 are symmetrically fixedly connected between the inner front wall of the connecting frame 4 and the front end of the vertical plate 2. A connecting plate 6 is fixedly connected to the output end of the transverse cylinder 3. Guide sleeves 7 are fixedly connected to both ends of the connecting plate 6. The two sets of guide sleeves 7 are slidably fitted onto the two sets of guide columns 5 respectively. A riveting cylinder 8 is fixedly installed at the top end of the connecting plate 6. A pressure block 9 is fixedly connected to the output end of the riveting cylinder 8. The fixed frame 10 is fixedly installed at the top end of the processing table 1. A positioning groove 14 is provided on the fixed frame 10. The positioning table 11 is engaged with the fixed frame 10 by cooperating with the positioning groove 14. Multiple deep holes 12 are equidistantly provided at the top end of the positioning table 11. The bottom of the positioning platform 11 is provided with multiple shallow holes 13 at equal intervals, and the diameter of the shallow holes 13 is larger than the diameter of the deep holes 12. In use, by activating the transverse cylinder 3, the transverse cylinder 3 can drive the connecting plate 6 to move back and forth under the guidance of the guide post 5 and the guide sleeve 7, so as to adjust the riveting position according to the hole position on the sheet metal part. Through the multiple deep holes 12 provided at the top of the positioning platform 11, the riveting bolts or riveting studs can be riveted on the pre-made holes on the inner or outer side of the sheet metal part. By flipping the positioning platform 11 over and placing it on the fixing frame 10, so that the shallow holes 13 face upward, the riveting nuts can be riveted on the pre-made holes on the inner or outer side of the sheet metal part. During riveting, by activating the riveting cylinder 8, the riveting cylinder 8 pushes the pressure block 9 downward, so that the pressure block 9 can rivet the riveting part into the sheet metal part. Thus, different riveting parts can be riveted according to the connection requirements of the sheet metal part, making the riveting device more flexible to use and improving its practicality.

[0022] Two sets of brackets 15 are symmetrically fixedly connected to the top of the processing table 1. The two sets of brackets 15 are distributed on the left and right sides of the fixed frame 10. Three sets of rollers 16 are rotatably installed on the two sets of brackets 15 at equal intervals. The outer wall of the top of the rollers 16 is aligned with the top of the positioning table 11. By setting up the brackets 15 and rollers 16, when riveting sheet metal parts, the brackets 15 and rollers 16 on both sides of the fixed frame 10 can support the sheet metal parts, making it easier and more convenient for workers to hold the sheet metal parts while riveting, and also making it easier to move and adjust the position of the sheet metal parts.

[0023] The positioning platform 11 is fixedly connected to the middle of both ends of the positioning platform 11. By setting the handling handle 17, the positioning platform 11 can be lifted from the positioning groove 14 by holding the handling handle 17, and then the positioning platform 11 can be flipped, making it more convenient to lift and flip the positioning platform 11.

[0024] Both sets of handles 17 are fixedly fitted with anti-slip handle sleeves 18 on their outer walls; by setting the anti-slip handle sleeves 18, when the hand holds the handle 17 to lift and flip the positioning platform 11, it is prevented from slipping and falling out of the hand.

[0025] The multiple deep holes 12 and shallow holes 13 can be of different diameters, with the diameter of the shallow hole 13 being larger than that of the deep hole 12; by setting multiple sizes, it is convenient to rivet parts of different thicknesses.

[0026] This utility model discloses a sheet metal riveting device. Its working principle is as follows: When riveting sheet metal parts, if the riveting component is a riveting bolt or riveting stud, the deep hole 12 can be positioned upwards. During riveting, the operator places the sheet metal part on the top of the positioning table 11 and adjusts the position of the pre-drilled hole at the riveting point to align it with the corresponding deep hole 12. The design of multiple deep holes 12 facilitates the alignment of pre-drilled holes at different positions on the sheet metal part. Then, the riveting bolt or riveting stud is inserted into the pre-drilled hole and the deep hole 12, with the embossed teeth on the riveting bolt or riveting stud facing downwards. By activating the transverse cylinder 3, the transverse cylinder 3 pushes the connecting plate 6 to move, causing the connecting plate 6 to move the riveting cylinder 8 and the pressure block 9 above the riveting point. Then, by activating the riveting cylinder 8, the riveting cylinder 8 pushes the pressure block 9 downwards, thereby riveting the sheet metal part upwards. The pressure block 9 rivets the rivet bolt or rivet stud into the pre-drilled hole of the sheet metal part to complete the riveting. If the riveted part is a thin plate and a rivet nut needs to be riveted, the positioning table 11 is lifted and flipped by holding the handle 17, and then the positioning table 11 is placed in the positioning groove 14 with the shallow hole 13 facing upwards for clamping. During riveting, the rivet nut is placed into the corresponding shallow hole 13 with the embossed teeth facing upwards. Then, the pre-drilled hole at the riveting point on the thin plate is aligned with the rivet nut. After adjusting the position of the pressure block 9 by the transverse cylinder 3, the riveting cylinder 8 is activated to push the pressure block 9 downwards, so that the pressure block 9 presses down on the thin plate, thereby pressing the embossed teeth on the rivet nut into the pre-drilled hole to complete the riveting of the rivet nut. During the entire riveting process, the operator needs to hold the sheet metal part for assistance to ensure the smooth riveting process.

[0027] The sheet metal processing riveting device of this utility model has common mechanical installation, connection or setting methods, and can be implemented as long as it can achieve its beneficial effect. The transverse cylinder 3 and the riveting cylinder 8 of the sheet metal processing riveting device of this utility model are purchased from the market. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
