Description

Technical Field

[0001] This utility model relates to the field of adjustable riveting machines, and more particularly to an adjustable riveting machine. Background Technology

[0002] A riveting machine is a mechanical device that joins metal parts through high-pressure stamping. It uses mechanical force to press rivets into pre-set grooves in the workpiece, firmly connecting plates of different materials and thicknesses. Riveting machines can not only quickly and securely connect parts, but this process also requires no auxiliary materials and has no special requirements for the surface of the workpiece.

[0003] Most common riveting machines can only press one rivet at a time, which is inefficient for large-scale riveting of the same type. For some more complex riveting processes, such as when there are multiple riveting points on a part, different riveting points need to be manually rotated or moved to a fixed position for machine riveting. This method is not only cumbersome to operate, but also, due to the limitation of multiple riveting points, the stability of the parts cannot be guaranteed when riveting one by one by the worker, which may result in weak riveting or riveting failure. Therefore, those skilled in the art have provided an adjustable riveting machine to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an adjustable riveting machine. In this device, both the lower and supporting horizontal and vertical plates have grooves. Multiple rivet punches and rivet dies are installed in the grooves of the vertical plates, enabling the simultaneous riveting of multiple parts and improving work efficiency. Through the grooves in each of the lower and supporting horizontal and vertical plates, along with the cooperation of scale lines and positioning plates, the rivet punches and rivet dies can move laterally and longitudinally, achieving more precise control over the position of each riveting point. This solves the problem of difficult riveting of certain special parts with multiple riveting points in different positions. This method provides stable support for the riveting points, reduces the time and human error associated with manual adjustment of part positions, and improves work efficiency, riveting quality, and the stability of product quality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable riveting machine, comprising a machine body, the machine body including a support body and a connecting column, the lower end of the connecting column being bolted to a pressing mechanism, the pressing mechanism including a pressing horizontal plate, the upper end of the pressing horizontal plate being provided with pressing horizontal grooves near the front and rear sides, both ends of the two pressing horizontal grooves being provided with threaded nails, four threaded nails being threadedly connected to a lever nut, the lower ends of the two pressing horizontal grooves being connected to pressing vertical plates through threaded nails and lever nuts, both pressing vertical plates being provided with pressing vertical grooves in the middle, and both pressing vertical grooves being provided with rivet protrusions; The machine body is fitted with a support mechanism, which includes a support horizontal plate. The upper end of the support horizontal plate is provided with support horizontal grooves near the front and rear sides. The upper ends of the two support horizontal grooves are connected to support vertical plates by threaded nails and pull plate nuts. The middle of the two support vertical plates is provided with support vertical grooves. Rivet concave molds are provided in the two support vertical grooves.

[0006] Furthermore, the rivet punch includes a threaded pressure column, and a protrusion is fixedly provided at the lower end of the threaded pressure column. The rivet punch is threadedly connected to a pull plate nut.

Four springs are uniformly fixedly connected inside the base, and a clamping plate is fixedly connected to the other end of each of the four springs. The multiple threaded support columns are threadedly connected to a lever nut.

[0011] Furthermore, a base is fixedly provided at the lower end of the support body, and the support mechanism is snapped onto the upper end of the base.

[0012] This utility model has the following beneficial effects: This utility model proposes an adjustable riveting machine. In this device, both the lower pressure horizontal and vertical plates and the supporting horizontal and vertical plates have slots. Multiple rivet punches and rivet dies can be installed in these slots, enabling the simultaneous riveting of multiple parts and improving work efficiency.

[0015] 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.

[0016] Reference Figure 1 , Figure 2 , Figure 5 , Figure 6 ,and Figure 7An embodiment of this utility model is provided: an adjustable riveting machine, including a machine body 1, the machine body 1 including a support body 101 and a connecting column 104, the lower end of the connecting column 104 is bolted to a pressing mechanism 2, the pressing mechanism 2 includes a pressing horizontal plate 201, the upper end of the pressing horizontal plate 201 is provided with pressing horizontal grooves 203 near the front and rear sides, both ends of the two pressing horizontal grooves 203 are provided with threaded nails 7, and four threaded nails 7 are threadedly connected to a lever nut 6, the lower end of the two pressing horizontal grooves 203 is connected to a pressing vertical plate 202 through the threaded nails 7 and the lever nut 6, both pressing vertical plates 202 are provided with pressing vertical grooves 204 in the middle, and both pressing vertical grooves 204 are provided with rivet punches 3; The body 1 is fitted with a support mechanism 4, which includes a support horizontal plate 401. The upper end of the support horizontal plate 401 is provided with support horizontal grooves 403 near the front and rear sides. The upper ends of the two support horizontal grooves 403 are connected to support vertical plates 402 by threaded nails 7 and pull plate nuts 6. The middle of the two support vertical plates 402 is provided with support vertical grooves 404, and rivet concave molds 5 are provided in the two support vertical grooves 404.

[0017] Specifically, the pressing horizontal plate 201 and pressing vertical plate 202 in the pressing mechanism 2 are respectively provided with pressing horizontal groove 203 and pressing vertical groove 204. The threaded nails 7 are connected to the lever nut 6. The rivet protrusion 3 in the pressing vertical groove 204 is also connected through the lever nut 6. By rotating the lever nut 6, the pressing vertical plate 202 and rivet protrusion 3 can be slid. With the support mechanism 4 of the same principle, the rivet points can be moved at will. If you want to rivet multiple rivet points at the same time, you can increase the number of pressing vertical plates 202 and rivet protrusion 3 as appropriate. It should be noted that for extremely special riveting processes, the work can continue by replacing the appropriate rivet punch 3 and rivet die 5. For riveting large flat workpieces, the rivet punch 3 and rivet die 5 can be added depending on the real-time situation, or part of the support mechanism 4 can be removed, using only the support plate 401 as the support for the riveted workpiece. For riveting large rivets, the pressing mechanism 2 can be removed and the connecting column 104 can be used in conjunction with the support plate 401 for riveting. This allows for riveting of a single riveting point, multiple riveting points, and even changing the positions of multiple riveting points. This enables one-time riveting of special parts that require the riveting of multiple parts, improving efficiency, reducing errors from manual riveting of multiple riveting points on special parts, and improving riveting quality.

[0018] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8The rivet punch 3 includes a threaded pressure column 301, with a protrusion 302 fixedly installed at the lower end of the threaded pressure column 301. The rivet punch 3 is threadedly connected to a lever nut 6. The rivet die 5 includes a multi-segment threaded support column 501, with a base 504 threadedly connected to the multi-segment threaded support column 501. Four springs 502 are evenly fixedly connected inside the base 504, and clamping plates 503 are fixedly connected to the other ends of the four springs 502. The multi-segment threaded support column 501 is threadedly connected to the lever nut 6. The base frames of the pressing mechanism 2 and the support mechanism 4 are both... Parallel and corresponding to each other, the surfaces of the lower horizontal plate 201, lower vertical plate 202, support horizontal plate 401 and support vertical plate 402 are all provided with scale lines. The rivet punch 3, rivet die 5, lower vertical plate 202 and support vertical plate 402 are all provided with positioning plates 8 at predetermined positions parallel to their corresponding scale lines. The upper end of the support body 101 is connected to a hydraulic cylinder 103, which is fixedly connected to the connecting column 104. The lower end of the support body 101 is fixedly provided with a base 102, and the support mechanism 4 is snapped onto the upper end of the base 102.

[0019] Specifically, the connection between the rivet punch 3, the rivet die 5, and a large number of threaded rivets 7 and the pull plate nut 6 ensures the stability of various mechanical structures during extrusion. All connections involving the pull plate nut 6 are equipped with spring washers to ensure the stability of the connection. The cooperation between the scale line and the positioning plate 8 can provide relatively accurate positioning when adjusting the position of each component. The slot at the lower end of the support plate 401 can engage with the base 102 to prevent slippage. The pressing mechanism 2 is bolted to the connecting column 104. The hydraulic cylinder 103, which is fixedly connected to the connecting column 104, is fixedly restricted on the support body 101. Under the above restriction, the pressing mechanism 2 and the support mechanism 4 can ensure the cooperation of the rivet punch 3 and the rivet die 5. The upper thread of the multi-segment threaded support column 501 in the rivet die 5 can be adjusted by cooperating with the base 504. The spring 502 and the clamping plate 503 can clamp the parts and are applicable to most parts with high adaptability. The top of the multi-segment threaded support column 501 has a disc to support the parts and ensure smooth riveting. The rivet can position the riveted parts so there is no need to worry about the positional relationship between the two parts. It is important to note here that the mechanical force for riveting is provided by hydraulic cylinder 103. (The working principle of the hydraulic cylinder is based on Pascal's law, achieving mechanical energy conversion through pressure transmission in a closed fluid. Its core process can be summarized as follows: a hydraulic pump injects high-pressure oil into the fixed chamber of the hydraulic cylinder; the oil pressure is evenly transmitted to the piston through seals, pushing the piston to move towards the low-pressure chamber. When reverse movement is required, the oil circuit is switched via a reversing valve, and the oil flows back from the high-pressure chamber to the oil tank. The piston moves in the opposite direction under gravity or spring force, at which point the pressure of the device gradually balances.) The pressure from hydraulic cylinder 103 is transmitted to connecting column 1. 04. The connecting column 104 transmits pressure to the lower horizontal plate 201, and then to the lower vertical plate 202. The rivet punch 3 is fixed to the upper plate nut 6. The rivet concave die 5 is fixed to the supporting vertical plate 402 by the upper plate nut 6. The supporting vertical plate 402 is fixed to the supporting horizontal plate 401 by the upper plate nut 6, thus supporting the rivet punch 3. The rivet punch 3 and the rivet concave die 5 cooperate to complete the riveting (riveting principle: the mechanical connection of metal components is achieved through the plastic deformation of the rivet. Its core is to use pressure to make the rivet form a strong locking structure in the connecting parts).

[0020] Working principle: During general riveting, rotate the lever nut 6 to slide the rivet punch 3 and rivet concave die 5. Use the scale lines on the lower pressure plate 202 and the support plate 402 to observe the position of the positioning plate 8 for positioning. Ensure that the rivet punch 3 and rivet concave die 5 are aligned and tighten the lever nut 6. Then, place the riveting parts and rivets on the plate and start the hydraulic cylinder 103 to rivet. If you want to rivet multiple parts at the same time, increase the number of rivet punches 3 and rivet concave dies 5 and adjust their positions before riveting. When riveting a part with multiple riveting points and special riveting point positions, measure the position of the riveting points, rotate the lever nut 6 to slide the rivet punch 3 and rivet concave die 5, and use the scale lines on the lower pressure plate 202 and the support plate 402 to observe the position of the positioning plate 8 for positioning. After reaching the predetermined position, tighten the lever nut 6 and start the hydraulic cylinder 103 to complete the riveting.

[0021] 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.
