Description

Technical Field

[0001] This utility model relates to the field of riveting machine technology, and more specifically, to a riveting machine with adaptive positioning. Background Technology

[0002] In the industrial manufacturing sector, riveting machines are key pieces of equipment widely used in riveting operations of various metal components. Their performance and functions directly affect riveting quality and production efficiency. During the riveting operation, stable clamping of the workpiece is a crucial prerequisite for ensuring riveting accuracy and reliability.

[0003] Currently, existing riveting machines generally have significant limitations in clamping workpieces to be riveted. Most traditional riveting machines have relatively fixed clamping mechanisms with limited clamping size ranges, making it difficult to automatically adjust the clamping according to the different sizes and shapes of the workpieces to be riveted. In actual production, the dimensions of the workpieces to be riveted often vary considerably. When dealing with workpieces smaller than the preset range of the clamping mechanism, the mechanism cannot fit tightly, causing the workpiece to wobble or shift during riveting, thus affecting the accuracy of the riveting position and reducing the riveting quality. Conversely, when encountering workpieces larger than the preset range, the workpiece may not be able to fit smoothly into the clamping mechanism. Even if it is forced into place, uneven clamping force distribution can cause excessive localized stress on the workpiece, leading to deformation or even damage.

[0004] Furthermore, due to the lack of adaptive automatic clamping adjustment function, operators need to frequently manually adjust the clamping mechanism according to workpieces of different sizes. This not only increases the difficulty and workload of operation and reduces production efficiency, but also makes it difficult to guarantee the accuracy of manual adjustment, further affecting the stability of riveting quality. Therefore, developing a riveting machine with adaptive positioning function that can automatically adjust the clamping according to the size of the workpiece to be riveted, in order to solve the above-mentioned problems in the existing technology, has important practical significance.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0032] Please see Figure 1-10 The present invention provides the following technical solution:

[0033] Embodiment 1 includes a housing 1, a movable seat 2 slidably disposed on the top of the housing 1, a buffer riveting table 3 slidably disposed below the movable seat 2, a riveting part 4 disposed at the bottom of the movable seat 2 and clearance-fitted with the buffer riveting table 3, and a material placement part 5 disposed below the buffer riveting table 3 for placing the workpiece to be riveted. The self-adaptive positioning riveting machine also includes an adaptive positioning mechanism 6 and a material picking mechanism 7; the adaptive positioning mechanism 6 is disposed on the material placement part 5, and the adaptive positioning mechanism 6 includes a first positioning part 61, a contact part 62, and an abutment part 63; the first positioning part 61 has a pair of parallel The first positioning part 61 is triangular in shape and has its corners triangular. The first positioning part 61 is located on both sides of the buffer riveting table 3. The contact part 62 is a pair and is slidably disposed on both sides of the material placement part 5. The contact part 62 is located below the first positioning part 61 and the top surface of the contact part 62 is triangular. The abutting part 63 is a pair and is disposed on both sides of the contact part 62. The abutting part 63 is used to clamp the workpiece to be riveted placed inside the material placement part 5. The material picking mechanism 7 is disposed on the top of the housing 1 and is used to quickly remove the riveted workpiece.

[0034] Specifically, the contact surface of the abutment part 63 facing the workpiece to be riveted has an open structure, and the two sides of the open structure are relatively close and inclined, so that when the workpiece to be riveted is abutted by the abutment part 63, the workpiece to be riveted can be restricted from sliding on the open structure and inclined surface of the abutment part 63 until the workpiece to be riveted is abutted by the abutment part 63. First, the workpiece to be riveted is placed on the top of the placement part 5 by means of a robotic arm or manual handling. In order to reduce work fatigue and improve placement accuracy, a robotic arm is preferred. The top of the movable seat 2 is provided with a hydraulic cylinder for driving the movable seat 2 to descend. When the hydraulic cylinder is activated, it can drive the movable seat 2 to a descending state. The buffer riveting table 3 is provided with multiple circular columns, which are clearance-fitted with the movable seat 2, and buffer springs are sleeved on the outer side of each of the multiple circular columns. When the moving seat 2 moves and drives the buffer riveting table 3 to move, until the buffer riveting table 3 and the riveting part 4 contact the top of the material placement part 5, the moving seat 2 continues to descend when they contact each other. At this time, the buffer spring is in a compressed state, and the moving seat 2 and the riveting part 4 continue to descend, so that the riveting workpiece placed inside the material placement part 5 can be riveted. When the robotic arm places the workpiece to be riveted on top of the placement section 5, the moving seat 2, the buffer riveting table 3, and the riveting section 4 descend. During this process, the buffer riveting table 3 can drive a pair of first positioning parts 61 to descend synchronously until the first positioning parts 61 contact the contact parts 62, driving the pair of contact parts 62 to move closer to each other until the contact parts 62 drive the abutment parts 63 to clamp the workpiece to be riveted placed inside the placement section 5. Since the workpieces are of different sizes, when the abutment parts 63 have finished clamping the workpiece to be riveted, the buffer riveting table 3 and the riveting section 4 continue to descend. At this time, because the buffer riveting table 3 is set with a circular column and a buffer spring, the moving seat 2 and the riveting section 4 can continue to descend and complete the riveting work of the workpiece to be riveted when the abutment parts 63 have clamped the workpiece to be riveted. This enables adaptive clamping of the workpiece to be riveted, placed inside the material placement section 5, allowing the abutment section 63 to clamp workpieces of different sizes and maintain their centered position relative to the riveting section 4 without affecting the normal operation of the riveting section 4. By setting the adaptive positioning mechanism 6, the problem of adaptive clamping of workpieces of different sizes is solved, achieving the effect of ensuring the normal operation of the riveting section while firmly clamping the workpiece, thus improving riveting efficiency and accuracy.

[0035] See Figures 3-5The adaptive positioning mechanism 6 also includes a guide portion 64 and a return spring 65. The guide portion 64 is disposed on the side of the contact portion 62 and is located between the contact portion 62 and the abutment portion 63. The guide portion 64 is in clearance fit with the material placement portion 5. The return spring 65 is disposed on the outside of the guide portion 64. One end of the return spring 65 is fixed to the material placement portion 5, and the other end of the return spring 65 is fixed to the contact portion 62. When the contact portion 62 moves toward the material placement portion 5, it can drive the return spring 65 to be in a compressed state.

[0036] Specifically, when the first positioning part 61 contacts the contact part 62, the contact part 62, the guide part 64, and the abutment part 63 can move synchronously. In this state, the return spring 65 is compressed. When the moving seat 2 rises, the pressure of the return spring 65 is released, pushing the contact part 62 and the abutment part 63 to slide away from the material placement part 5. This ensures that when the riveting work is completed and the moving seat 2 rises, the abutment part 63 and the contact part 62 can return to their initial positions, facilitating subsequent unloading of the riveted workpiece.

[0037] See Figures 6-8 The adaptive positioning mechanism 6 also includes a limiting part 66 and a sliding part 67; the limiting part 66 has multiple parts and is respectively disposed on the side of the abutting part 63, and the abutting part 63 is provided with a mounting groove for mounting the limiting part 66; the sliding part 67 has multiple parts and is respectively slidably disposed on the outside of the limiting part 66, and when the sliding part 67 moves, it can abut against the outside of the workpiece to be riveted placed inside the material placement part 5.

[0038] Specifically, when the abutting part 63 clamps both sides of the workpiece to be riveted, in order to ensure the centering of the workpiece to be riveted inside the material placement part 5, the sliding part 67 can first move along the limiting part 66 until the multiple sliding parts 67 abut against the outside of the workpiece to be riveted. At this time, it can be ensured that the workpiece to be riveted is in the center position of the riveting part 4, thus ensuring the centering effect of the workpiece to be riveted.

[0039] See Figures 6-8 The adaptive positioning mechanism 6 also includes a sliding plate 68, a displacement part 69, and a first telescopic cylinder 691; the sliding plate 68 is slidably disposed on the top of the housing 1 and is located at the bottom of the material placement part 5; the displacement part 69 has multiple displacement parts and is slidably disposed on the top of the sliding plate 68, and the top of the sliding plate 68 is provided with a slot for the multiple displacement parts 69 to slide; the first telescopic cylinder 691 has multiple displacement parts and is disposed on the top of the displacement parts 69, and the output ends of the multiple first telescopic cylinders 691 are all connected to the sliding part 67.

[0040] Specifically, the top of the sliding plate 68 is provided with a pair of fixing parts for limiting the sliding of the contact part 62 away from the material placement part 5. The fixing parts are L-shaped blocks. When the first positioning part 61 is not in contact with the contact part 62 and the return spring 65 is released, it can drive the contact part 62 to abut against the fixing parts. In this state, the contact part 62 stops moving and returns to its initial position. In order to drive the multiple sliding parts 67 to abut against the outside of the workpiece to be riveted, the first telescopic cylinder 691 is first activated and drives the sliding part 67 to move, which can then achieve position adjustment of the sliding part 67. When the contact part 62 and the abutting part 63 move, the sliding part 67 and the first telescopic cylinder 691 can drive the displacement part 69 to move synchronously along the top of the sliding plate 68. In order to reduce the stability of the return spring 65 when releasing pressure, the contact surface between the sliding plate 68 and the displacement part 69 can be coated with lubricating oil to improve the smoothness of sliding between the displacement part 69 and the sliding plate 68 and reduce the sliding contact friction between the displacement part 69 and the sliding plate 68. The first telescopic cylinder 691 is mounted on the sliding plate 68 via the displacement part 69, thereby reducing the pressure when the contact part 62 resets and ensuring the smoothness of the contact part 62 reset.

[0041] See Figure 9 and Figure 10 The material handling mechanism 7 includes a mounting frame 71, a sliding frame 72, and an adsorption part 73. The mounting frame 71 is located on the side of the housing 1 and above the sliding plate 68. The sliding frame 72 is slidably disposed on the outside of the mounting frame 71. The adsorption part 73 is disposed at the bottom end of the sliding frame 72 and is used to adsorb the riveted workpiece in the material placement part 5.

[0042] Specifically, after the riveting work is completed, the sliding frame 72 slides down along the mounting frame 71, and when the sliding frame 72 descends, it can drive the adsorption part 73 to descend synchronously until the adsorption part 73 stops above the material placement part 5.

[0043] See Figure 9 and Figure 10 The material handling mechanism 7 also includes a linear guide rail 74 and an electric slide rail 75; the linear guide rail 74 is a pair and is respectively disposed on the top of the housing 1, and both of the linear guide rails 74 are located below the sliding plate 68; the electric slide rail 75 is a pair and is respectively slidably disposed on the top of the linear guide rail 74, and the top of both of the electric slide rails 75 are connected to the sliding plate 68, so that when the electric slide rail 75 moves, it can drive the sliding plate 68 to move synchronously.

[0044] Specifically, when the adsorption section 73 descends, the electric slide rail 75 slides along the linear guide rail 74 in a direction close to the mounting bracket 71 until the electric slide rail 75 drives the sliding plate 68 to be below the adsorption section 73 and stops sliding. At this time, the adsorption section 73 continues to descend until it contacts the processed workpiece and stops descending.

[0045] See Figure 9 and Figure 10 The material handling mechanism 7 also includes a second telescopic cylinder 76 and a vacuum pump 77; the second telescopic cylinder 76 has a pair and is respectively disposed on the top of the mounting frame 71, and the output ends of the pair of second telescopic cylinders 76 are connected to the sliding frame 72; the vacuum pump 77 is disposed on the sliding frame 72 and is connected to the adsorption part 73.

[0046] Specifically, when the adsorption part 73 is attached above the material placement part 5, the adsorption part 73 is preferably a vacuum suction cup. When the vacuum pump 77 is started, the adsorption part 73 can stably adsorb the processed workpiece. After adsorption, the adsorption part 73 drives the processed workpiece to rise. In this state, the sliding frame 72 rises, and then the robotic arm picks up the adsorbed workpiece. When picking up, the vacuum pump 77 is turned off, thereby realizing the rapid transfer of the processed workpiece.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
