Description

Technical Field

[0001] This utility model specifically relates to the field of riveting machine technology, and more specifically to a riveting mechanism for a cabinet mounting plate. Background Technology

[0002] Riveting of rack mounting plates is a process in which rivets are attached to rack mounting plates (usually sheet metal parts). Through external force, nuts, screws, etc., are forced into pre-made grooves or holes, causing cold extrusion deformation of the plate material to form a strong connection. For example, press-fit nuts are typically round with knurled teeth. They are pressed into holes in the sheet metal part, where the hole diameter is smaller than the outer diameter of the knurled teeth. Under pressure, plastic deformation occurs around the hole, creating a tightening effect.

[0031] 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.

[0032] Please see Figure 1-6In this embodiment of the utility model, a cabinet mounting plate riveting mechanism includes a riveting machine 1. The riveting machine 1 has a rivet holding assembly 5 and a bottom mold base 4 below the riveting head. The rivet holding assembly 5 includes a bottom shell 53, and a double-rod cylinder 54 is fixed inside the bottom shell 53. Two rotating shafts 55 are fixed to the cylinder rod end of the double-rod cylinder 54, and a flip plate 56 is rotatably connected to each rotating shaft 55. A torsion spring is also installed inside the flip plate 56 and the rotating shaft 55 to realize the self-resetting of the flip plate 56.

[0033] A top cover plate 52 is fastened to the top of the bottom shell 53. The top cover plate 52 has a material inlet for easy entry of rivets, and a conveying pipe 57 for conveying rivets is connected to the material inlet.

[0034] More specifically, there is a recess between the two flaps 56 to facilitate the rivet falling in; when the double-rod cylinder 54 is in the retracted state, the recess is located directly below the material opening on the upper cover plate 52.

[0035] When the double-rod cylinder 54 is in the extended state, the groove is located directly below the riveting head of the riveting machine 1.

[0036] By adopting the above technical solution, when riveting the rack mounting plate, the prepared rack mounting plate is first placed between the riveting head and the bottom mold base 4. The double-rod cylinder 54 extends and pushes the flip plate 56 carrying the rivets to the bottom of the riveting head. The riveting machine 1 works, the riveting head extends downward, and under the rapid push of the riveting head, the flip plate 56 is forced to rotate 90 degrees quickly, so that the rivets are quickly riveted onto the rack mounting plate.

[0037] When the riveting head resets, the flip plate 56 reverses 90 degrees to reset under the action of the torsion spring; then the cylinder rod of the double-rod cylinder 54 retracts, so that the sink groove on the flip plate 56 is located directly below the material opening on the upper cover plate 52; the rivets conveyed from the conveying pipe 57 will fall onto the sink groove and automatically align themselves; thus facilitating the riveting process of the next cabinet mounting plate.

[0038] The above technical solution eliminates the need for manual handling and straightening of each rivet, greatly reducing labor intensity. Furthermore, the flip plate 56 can straighten the rivets, effectively preventing them from skewing during riveting and improving the product qualification rate.

[0039] In this embodiment, a hanger 51 is fixed on the upper cover plate 52. The hanger 51 consists of two L-shaped brackets, which are fixed together by bolts and can be adjusted in length.

[0040] By adopting the above technical solution, the height of the double-rod cylinder 54 is adjustable, so that its height can be adjusted adaptively according to products of different thicknesses.

[0041] In this embodiment, the bottom mold base 4 is fixed on the slide block 3; the slide block 3 is slidably connected to the slide rail 2 fixed on one side of the riveting machine 1. The bottom of the slide block 3 is fixed on the threaded adjusting member 7.

[0042] More specifically, the threaded adjustment component 7 includes a trapezoidal seat with a through hole in the middle and a handwheel rotatably connected to the top; the handwheel has a thread inside and a screw is threadedly connected to it, and the upper end of the screw is fixed to the slide 3; therefore, when the handwheel is rotated, the screw can drive the slide 3 to adjust up and down, so as to be suitable for riveting of products of different thicknesses.

[0043] In this embodiment, a side platform 8 is also fixed on one side of the riveting machine 1, and a rivet feeding mechanism 6 is installed on the side platform 8.

[0044] The rivet feeding mechanism 6 has a vibrating feeding plate 61, on which a feeding frame 62 is fitted; the end of the feeding frame 62 is provided with a guide frame 63; the guide frame 63 has a sliding groove to facilitate the passage of rivets, and a dropping hole is opened at the end of the sliding groove; the dropping hole is connected to the conveying pipe 57.

[0045] An air blowing pipe 66 is provided above the material discharge hole. The air blowing pipe 66 is connected to an air source, and a pneumatically controlled solenoid valve 65 is also installed on the air blowing pipe 66. A pusher cylinder 64 is fixed at one end of the guide frame 63, and the pusher cylinder 64 is located in the chute.

[0046] By adopting the above technical solution, during the feeding process, a large number of rivets are placed in the vibrating feeding plate 61. The vibrating feeding plate 61 arranges and transports the rivets one by one to the feeding frame 62, and then slides into the groove of the guide frame 63. Subsequently, the pusher cylinder 64 pushes out the cylinder rod, pushing the rivets into the dropping hole. The pneumatic control solenoid valve 65 is opened, and compressed gas blows the rivets toward the conveying pipe 57, thereby realizing the transmission of the rivets.

[0047] The above solution effectively solves the problem of tedious manual material handling and improves equipment processing efficiency.

[0048] The working principle of this utility model is as follows: During feeding, a large number of rivets are placed in the vibrating feeding plate 61. The vibrating feeding plate 61 arranges and conveys the rivets one by one to the feeding frame 62, and then slides into the sliding groove of the guide frame 63. Subsequently, the pusher cylinder 64 pushes out the cylinder rod, pushing the rivets into the dropping hole; the pneumatic control solenoid valve 65 is opened, and compressed gas blows the rivets towards the conveying pipe 57, thereby realizing the transmission of the rivets; the rivets conveyed from the conveying pipe 57 will fall onto the settling trough and automatically straighten their position.

[0049] The prepared rack mounting plate is placed between the riveting head and the bottom mold base 4. The double-rod cylinder 54 extends, pushing the flip plate 56 carrying rivets below the riveting head. The riveting machine 1 operates, and the riveting head extends downward. Under the rapid push of the riveting head, the flip plate 56 is forced to rotate 90 degrees quickly, so that the rivets are quickly riveted onto the rack mounting plate. When the riveting head returns to its original position, the flip plate 56 rotates 90 degrees to return to its original position under the action of the torsion spring. Then the cylinder rod of the double-rod cylinder 54 retracts, so that the groove on the flip plate 56 is located directly below the material opening on the upper cover plate 52. The rivets conveyed from the conveying pipe 57 will fall back onto the groove and automatically align themselves, thus facilitating the riveting process of the next rack mounting plate.
