Description

Technical Field

[0001] This utility model relates to the field of riveting machine technology, and in particular to an automatic positioning structure for a riveting machine. Background Technology

[0002] A riveting machine is a mechanical device used for metal processing and assembly. It is mainly used to press or fix rivets or riveted parts onto workpieces. It fixes the rivets in the material by applying pressure to form a stable connection. Riveting machines are widely used in industrial fields such as automobiles, aviation, electronics and home appliances. With the rapid development of modern industry, riveting technology has been widely used in many fields such as automobile manufacturing, electronic products and mechanical equipment. In the process of riveting workpieces, positioning processing is usually required, so an automatic positioning structure for the riveting machine is needed.

[0003] In traditional riveting machine operation, workpiece positioning mainly relies on manual operation. The accuracy of manual positioning is highly dependent on the operator's experience and skill level. Different operators may have different positioning results. Even experienced operators may find it difficult to maintain completely consistent positioning in multiple operations, which can easily lead to deviations in the riveting position, thereby affecting the overall quality and consistency of the product and increasing the risk of rework and scrap. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an automatic positioning structure for a riveting machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic positioning structure for a riveting machine includes a base, a mounting seat on the top of the base, a first moving mechanism for moving the mounting seat on the top of the base, a connecting plate on the top of the mounting seat, a second moving mechanism for moving the connecting plate on the top of the mounting seat, clamping plates on both sides of the top of the connecting plate, two triangular blocks symmetrically fixed to the inner sidewalls of the two clamping plates, a third moving mechanism for moving the two triangular blocks on the top of the connecting plate, and a fixing mechanism for fixing the base at the bottom. During use, the design of the first, second, and third moving mechanisms eliminates the need for manual operation in workpiece positioning, avoiding riveting position deviations caused by differences in operator skill, thus significantly improving riveting accuracy and consistency. The fixing mechanism and design allow for quick fixing or disassembly between the device and the riveting machine without the need for bolts and nuts, simplifying operation, saving time, and improving work efficiency.

[0007] As a further embodiment of this utility model, the first moving mechanism includes two first sliding grooves, which are symmetrically opened at both ends of the top of the base. A first sliding rod is fixed inside each of the two first sliding grooves, and a first slider is sleeved on the side wall of each of the two first sliding rods. The two first sliders are fixed to the middle of the bottom ends of the mounting base. A second sliding groove is opened at the middle of the top of the base. A first lead screw is rotatably connected inside the second sliding groove. A first lead screw nut is sleeved on the side wall of the first lead screw, and the first lead screw nut and the first lead screw are adapted to each other. The first lead screw nut is fixed to the middle of the bottom of the mounting base. A first motor is fixed on the outer wall of the base, and the output shaft of the first motor is fixed to the first lead screw. The first motor drives the first lead screw to rotate. Under the constraint of the two first sliding rods and the two first sliders, the mounting base moves back and forth along the top of the base through the first lead screw nut.

[0008] As a further embodiment of this utility model, the second moving mechanism includes four first support plates, which are respectively fixed at the four corners of the top of the mounting base. The inner sidewalls of two first support plates on the same side are fixed with the same second sliding rod. The sidewalls of the two second sliding rods are fitted with second sliders, and the two second sliders are fixed to the bottom of the connecting plate. The middle of both ends of the top of the mounting base is fixed with a second support plate. The inner sidewalls of the two second support plates are rotatably connected with the same second lead screw. The sidewalls of the second lead screw are fitted with a second lead screw nut, and the second lead screw nut and the second lead screw are adapted to each other. The second lead screw nut is fixed to the middle of the bottom of the connecting plate. The outer sidewall of one of the second support plates is fixed with a second motor, and the output shaft of the second motor is fixed to the second lead screw. The second motor drives the second lead screw to rotate. Under the constraint of the two second sliding rods and the two second sliders, the connecting plate moves left and right along the top of the mounting base through the second lead screw nut.

[0009] As a further embodiment of this utility model, the third moving mechanism includes two third support plates, which are symmetrically fixed to one end of the top of the connecting plate.

Under the constraint of the two first sliding rods 6 and the two first sliders 7, the mounting base 2 is moved back and forth along the top of the base 1 by the first lead screw nut 9.

[0023] In this embodiment, the second moving mechanism includes four first support plates 12, which are respectively fixed at the four corners of the top of the mounting base 2. The inner sidewalls of two first support plates 12 located on the same side are fixed with the same second slide rod 13. The sidewalls of the two second slide rods 13 are each fitted with a second slider 14, and the two second sliders 14 are fixed to the bottom of the connecting plate 3. The middle of both ends of the top of the mounting base 2 are fixed with second support plates 15. The inner sidewalls of the two second support plates 15 are rotatably connected with the same second lead screw 16. The sidewalls of the second lead screw 16 are fitted with a second lead screw nut 17, and the second lead screw nut 17 is adapted to the second lead screw 16. The second lead screw nut 17 is fixed to the middle of the bottom of the connecting plate 3.

Under the constraint of the two second slide rods 13 and the two second sliders 14, the connecting plate 3 is moved left and right along the top of the mounting base 2 by the second lead screw nut 17.

[0024] In this embodiment, the third moving mechanism includes two third support plates 22, which are symmetrically fixed to one end of the top of the connecting plate 3. The inner sidewalls of the two third support plates 22 are rotatably connected to the same bidirectional lead screw 23. The sidewalls of the bidirectional lead screw 23 are symmetrically fitted with two third lead screw nuts 24, and both third lead screw nuts 24 are adapted to the bidirectional lead screw 23.

The other end of the top of the connecting plate 3 is fixed with a slide block 19. The top of the slide block 19 is symmetrically provided with two third sliders 20, and the two third sliders 20 are respectively fixed to the other end of the two clamping plates 21. The third motor 25 drives the bidirectional lead screw 23 to rotate, and the two third lead screw nuts 24 and the two third sliders 20 drive the two clamping plates 21 to move closer to each other, thereby driving the four triangular blocks 26 to move closer to each other in pairs, so as to clamp and fix the workpiece.

[0025] In this embodiment, the fixing mechanism includes two electromagnets 11. Two grooves are provided at the bottom of the base 1. The two electromagnets 11 are fixed on the inner sidewalls of the two electromagnets 11 respectively. When the two electromagnets 11 are energized, a magnetic field is generated around them, making the surface of the two electromagnets 11 magnetic. This allows the base 1 to be firmly attached to the operating platform of the riveting machine. Later, the two electromagnets 11 only need to be de-energized, and the magnetism on the surface of the two electromagnets 11 will disappear, making the entire device easy to remove without the need for bolts and nuts to lock it. The operation is simple and easy to install and disassemble.

[0026] Working Principle: During use, the entire device is placed on the operating platform of the riveting machine, and the power switches of the two electromagnets 11 are turned on. When the two electromagnets 11 are energized, a magnetic field is generated around them, making their surfaces magnetic. This allows the base 1 to be firmly attached to the operating platform of the riveting machine. Later, simply de-energize the two electromagnets 11, and the magnetism on their surfaces disappears, allowing the entire device to be easily removed without the need for bolts and nuts for locking. The operation is simple and easy to install and disassemble. After installation, the workpiece is placed on top of the connecting plate 3, and the power switch of the third motor 25 is turned on. The third motor 25 drives the bidirectional lead screw 23 to rotate. This, along with the two third lead screw nuts 24 and the two third sliders 20, causes the two clamping plates 21 to move closer together, which in turn causes the four triangular blocks 26 to move closer together in pairs, thus clamping the workpiece. After fixing, when the position of the workpiece needs to be adjusted, the power switch of the first motor 4 is turned on, driving the first motor 4 to rotate the first lead screw 10. Under the constraint of the two first slide rods 6 and the two first sliders 7, the first lead screw nut 9 drives the mounting base 2 to move back and forth along the top of the base 1. At the same time, the power switch of the second motor 18 is turned on, driving the second motor 18 to rotate the second lead screw 16. Under the constraint of the two second slide rods 13 and the two second sliders 14, the second lead screw nut 17 drives the connecting plate 3 to move left and right along the top of the mounting base 2. That is, the connecting plate 3 can move in the front, back, left and right directions, thus allowing the workpiece to move in any direction. During the process, no manual positioning is required, which can maintain a completely consistent positioning of the workpiece, avoid deviations in the riveting position, thereby increasing the overall quality and consistency of the product and reducing the risk of rework and scrap.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
