Description

Technical Field

[0001] This utility model relates to the field of sheet metal production, and in particular to a sheet metal riveting machine. Background Technology

[0002] A riveting machine is a new type of riveting equipment developed based on the principle of cold rolling; it refers to mechanical equipment that uses rivets to rivet items together. This equipment has a compact structure, stable performance, and is convenient and safe to operate. Riveting machines mainly rely on rotation and pressure to complete assembly and are primarily used in applications requiring riveting. Common types include pneumatic, hydraulic, and electric riveting machines, as well as single-head and double-head models. The most common types are automatic riveting machines and spin riveting machines.

[0003] Some sheet metal parts require riveting during production. The riveting method involves a worker holding the sheet metal part and placing the riveting hole on the outside of a support post, then using a riveting machine in conjunction with the support post to achieve riveting. However, the inventor found in actual use that when the sheet metal part is large, the riveting hole needs to be manually inserted into the outside of the support post. Due to the large size of the sheet metal part, it is impossible to directly observe the bottom of the sheet metal part, requiring manual manipulation of the sheet metal part little by little to align the holes, resulting in low riveting efficiency. Therefore, a sheet metal riveting machine is proposed to address the above problems. Utility Model Content

[0004] In view of the above-mentioned problems in the prior art, the main purpose of this utility model is to provide a sheet metal riveting machine, which can accurately press the sheet metal parts into the positioning rod through the pre-installation mechanism, and the pre-installation mechanism can be removed to facilitate the riveting machine to perform riveting work on the sheet metal parts.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a sheet metal riveting machine, including a mounting base;

[0006] A movable frame is installed on the top of the mounting base, a vertically set riveting machine is installed on one side of the movable frame, and a positioning rod that is fixedly connected to the mounting base is installed below the riveting machine.

[0007] The side of the mobile frame is also equipped with a mounting bracket, and the bottom of the mounting bracket is equipped with a first hydraulic rod arranged longitudinally. The moving end of the first hydraulic rod is fixedly connected to a moving plate, and the bottom of the moving plate is fixedly connected to a second hydraulic rod arranged laterally. The free end of the second hydraulic rod is fixedly connected to a pre-installation mechanism arranged vertically.

[0008] Furthermore, the top of the positioning rod is arc-shaped.

[0009] Some sheet metal parts require riveting during production. The riveting process typically involves a worker holding the sheet metal part and placing the riveting hole on the outside of a support post, then using a riveting machine in conjunction with the support post to rivet it. However, the inventors discovered that when the sheet metal part is large, the riveting hole needs to be manually inserted into the support post. Due to the large size of the sheet metal part, it's impossible to directly observe its bottom, requiring manual manipulation to align the holes, resulting in low riveting efficiency. By using a longitudinally positioned first hydraulic rod and a transversely positioned second hydraulic rod, a pre-installation mechanism can be moved. During installation, the riveting hole aligns with the pre-installation mechanism, and the first and second hydraulic rods are reset to quickly position the riveting hole above the positioning rod. The pre-installation mechanism then precisely presses the sheet metal part into the positioning rod, and the mechanism is then removed, facilitating the riveting machine's work.

[0010] Furthermore, the pre-installation mechanism includes a vertically arranged mounting cylinder that is fixedly connected to the second hydraulic rod. An electromagnet is installed inside the mounting cylinder, and a vertically arranged guide rod is fixedly connected below the electromagnet.

[0011] Furthermore, a sliding sleeve is slidably connected to the outer side of the guide rod, a suction ring is fixedly connected to the top of the sliding sleeve, a spring is fixedly connected to the other end of the suction ring, the other end of the spring is fixedly connected to the electromagnet, and a pressure ring is fixedly connected to the bottom of the sliding sleeve.

[0012] Furthermore, the suction ring is made of a block of metal iron.

[0013] Furthermore, the lower pressure ring is made of rubber sheet.

[0014] Furthermore, the inside of the mounting cylinder is equipped with two symmetrically arranged blocking blocks distributed vertically, and the vertical distance between two horizontal blocking blocks is less than the diameter of the suction ring.

[0015] During sheet metal installation, the guide rod is positioned above the sheet metal part, allowing workers to easily fit the riveting holes of the sheet metal part onto the outside of the guide rod. The first and second hydraulic rods then guide the part to the top of the positioning rod. When the electromagnet is de-energized, the compressed spring is released, which in turn drives the suction ring, sliding sleeve, and lower pressure ring to move. The lower pressure ring presses against the sheet metal part, ensuring that the sheet metal part is stably fitted onto the outside of the positioning rod, facilitating subsequent riveting work.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] The first hydraulic rod, which is set vertically, and the second hydraulic rod, which is set horizontally, can drive the pre-installation mechanism to move. When the sheet metal part is installed, the riveting hole of the sheet metal part is engaged with the pre-installation mechanism. Then, by resetting the first and second hydraulic rods, the riveting hole of the sheet metal part can be quickly moved to the position above the positioning rod. The pre-installation mechanism can accurately press the sheet metal part into the positioning rod. Then the pre-installation mechanism is removed, which makes it convenient for the riveting machine to perform riveting work on the sheet metal part.

[0018] During sheet metal installation, the guide rod is positioned above the sheet metal part, allowing workers to easily fit the riveting holes of the sheet metal part onto the outside of the guide rod. The first and second hydraulic rods then guide the part to the top of the positioning rod. When the electromagnet is de-energized, the compressed spring is released, which in turn moves the suction ring, sliding sleeve, and lower pressure ring. The lower pressure ring presses against the sheet metal part, ensuring that it is stably fitted onto the outside of the positioning rod, facilitating subsequent riveting work.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Example

[0024] A sheet metal riveting machine, such as Figure 1-3 As shown, it includes mounting base 1;

[0025] A movable frame 2 is installed on the top of the mounting base 1, a vertically arranged riveting machine 3 is installed on one side of the movable frame 2, and a positioning rod 4 is fixedly connected to the mounting base 1 below the riveting machine 3.

[0026] The side of the movable frame 2 is also equipped with a mounting frame 5. The bottom of the mounting frame 5 is equipped with a first hydraulic rod 6 arranged longitudinally. The movable end of the first hydraulic rod 6 is fixedly connected to a movable plate 7. The bottom of the movable plate 7 is fixedly connected to a second hydraulic rod 8 arranged laterally. The free end of the second hydraulic rod 8 is fixedly connected to a pre-installation mechanism 9 arranged vertically.

[0027] The top of the positioning rod 4 is arc-shaped.

[0028] Some sheet metal parts require riveting during production. The riveting method involves a worker holding the sheet metal part and placing the riveting hole on the outside of a support post, then using a riveting machine in conjunction with the support post to rivet the parts. However, the inventors discovered during actual use that when the sheet metal part is large, the riveting hole needs to be manually inserted into the outside of the support post. Due to the large size of the sheet metal part, it is impossible to directly observe the bottom of the part, requiring manual manipulation of the part to align the holes, resulting in low riveting efficiency. By using a longitudinally arranged first hydraulic rod 6 and a transversely arranged second hydraulic rod 8, the pre-installation mechanism 9 can be moved. During installation, the riveting hole of the sheet metal part aligns with the pre-installation mechanism 9, and then the first hydraulic rod 6 and the second hydraulic rod 8 are reset to quickly position the riveting hole of the sheet metal part above the positioning rod 4. The pre-installation mechanism 9 can then precisely press the sheet metal part into the positioning rod 4, and then the pre-installation mechanism 9 is removed, facilitating the riveting machine 3 to perform the riveting work on the sheet metal part.

[0029] For small sheet metal parts, only the second hydraulic rod 8 can be activated to push the pre-installation mechanism 9 to one side, so that the rivet holes of the small sheet metal parts can be fitted into the bottom of the pre-installation mechanism 9. Then the second hydraulic rod 8 is reset, which moves the small sheet metal parts to the position above the positioning rod 4. Then the pre-installation mechanism 9 will fit the sheet metal parts onto the positioning rod 4.

[0030] The pre-installation mechanism 9 includes a vertically arranged mounting cylinder 901 that is fixedly connected to the second hydraulic rod 8. An electromagnet 902 is installed inside the mounting cylinder 901, and a vertically arranged guide rod 903 is fixedly connected below the electromagnet 902.

[0031] A sliding sleeve 904 is slidably connected to the outer side of the guide rod 903. A suction ring 905 is fixedly connected to the top of the sliding sleeve 904. A spring 908 is fixedly connected to the other end of the suction ring 905. The other end of the spring 908 is fixedly connected to the electromagnet 902. A pressure ring 906 is fixedly connected to the bottom of the sliding sleeve 904.

[0032] The suction ring 905 is made of a block of metal iron.

[0033] The pressure ring 906 is made of rubber sheet.

[0034] The mounting cylinder 901 has two symmetrically arranged blocking blocks 907 arranged vertically inside, and the vertical distance between two horizontal blocking blocks 907 is less than the diameter of the suction ring 905.

[0035] During sheet metal installation, the guide rod 903 is positioned above the sheet metal part, making it convenient for workers to fit the riveting holes of the sheet metal part onto the outside of the guide rod 903. The guide rod 903 is then guided by the first hydraulic rod 6 and the second hydraulic rod 8 to the top of the positioning rod 4. Then, the electromagnet 902 is de-energized, and the compressed spring 908 is released, which can drive the suction ring 905, the sliding sleeve 904 and the lower pressure ring 906 to move. The lower pressure ring 906 presses the sheet metal part to ensure that the sheet metal part is stably fitted onto the outside of the positioning rod 4, which facilitates subsequent riveting work.

[0036] When the sheet metal part is fitted outside the guide rod 903, it is reset under the action of the second hydraulic rod 8. During this process, the electromagnet 902 is in the activated state. When the sheet metal part is above the positioning rod 4, the electromagnet 902 is turned off, and the attraction ring 905 can move. Under the action of the spring 908, the attraction ring 905 drives the sliding sleeve 904 to press downward. The sliding sleeve 904 drives the lower pressure ring 906 to move downward and press the sheet metal part. At this time, the riveting hole of the sheet metal part can be quickly fitted outside the positioning rod 4, which is convenient for subsequent processing. The electromagnet 902 is an existing technology product, so it will not be described in detail here. The lower pressure ring 906 is made of rubber block. When it comes into contact with the sheet metal part, it avoids damage to it and ensures its quality. The attraction ring 905 is made of metal iron block, which makes it easy for the electromagnet 902 to attract it when it is energized, thereby compressing the spring 908 and facilitating the subsequent pressing action.

[0037] Finally, it should be noted that the above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
