Description

Technical Field

[0001] This invention relates to the field of riveting technology, and more particularly to a reverse riveting device capable of dual-station exchange. Background Technology

[0002] Riveting equipment is a device that achieves riveting by pressing rivets into workpieces. The process involves first mounting the workpiece on a fixture, then installing the rivets at the corresponding positions on the workpiece or onto the rivet head, and finally pressing down on the rivet head to achieve riveting.

[0003] However, existing riveting equipment only has one fixture for mounting the workpiece. During batch riveting, after the previous riveting is completed, the current workpiece must be removed, a new workpiece must be installed, and only then can the next riveting be performed. In other words, the riveting head is idle during the process of removing the previous workpiece and installing the next workpiece, resulting in low efficiency for batch riveting. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the present invention is to propose a reverse riveting device that can realize dual-station exchange, so as to solve the problem of low efficiency of batch riveting in the prior art.

[0005] The technical solution adopted by this invention to solve its technical problem is a reverse riveting device capable of dual-station exchange, comprising:

[0006] A riveting assembly, comprising an upper riveting head movable in the height direction, with a riveting station below the upper riveting head;

[0007] A first workbench and a second workbench are used for mounting workpieces. The first workbench can move horizontally at a first height to enter or exit the riveting station. The second workbench can move horizontally at a second height and can move vertically to enter or exit the riveting station.

[0008] Furthermore, it also includes two synchronous pulleys and a synchronous belt simultaneously wound around the two synchronous pulleys. The synchronous belt includes a first component on one side of the two synchronous pulleys and a second component on the other side of the two synchronous pulleys, and the first component and the second component move in opposite directions.

[0009] The first workbench is connected to the first component, and the second workbench is connected to the second component.

[0010] Furthermore, it also includes:

[0011] The mounting frame has a first slide rail and a second slide rail arranged horizontally on it, and the first worktable is slidably mounted on the first slide rail;

[0012] A sliding block is slidably mounted on the second slide rail, and a first lead screw is rotatably connected to the sliding block along the height direction, and the first lead screw is threadedly connected to the second worktable.

[0013] Furthermore, the riveting assembly also includes a movable column and a fixed column, the movable column being movable relative to the fixed column along the height direction; a driving component is provided on the movable column, the driving component being used to drive the upper riveting head to move along the height direction;

[0014] The movable column is also provided with a lower pressure rivet head, which is located on the side of the workpiece away from the upper pressure rivet head.

[0015] Furthermore, a balancing cylinder is provided on the fixed column, and the telescopic rod of the balancing cylinder is connected to the movable column to provide the movable column with a force that is opposite in direction and equal in magnitude to the gravity of the movable column.

[0016] Furthermore, the riveting assembly can slide in a direction toward or away from the first worktable or the second worktable.

[0017] Furthermore, the reverse riveting device also includes a mounting bracket;

[0018] The fixed column and the mounting frame are slidably connected.

[0019] Furthermore, a second lead screw arranged in a horizontal direction is rotatably connected to the mounting bracket, and the second lead screw is threadedly connected to the fixed column.

[0020] Compared with the prior art, the present invention has at least the following beneficial effects:

[0021] (1) A first workbench and a second workbench are set up, both of which can be used to install workpieces. When one workbench is riveting, the other workbench can be used for workpiece replacement and other processes. The riveting process and the workpiece replacement process are carried out simultaneously, which greatly improves the efficiency of batch riveting.

[0022] (2) Set up a timing belt and timing pulley to connect the first worktable to the first component and the second worktable to the second component. Since the first component and the second component can move synchronously in opposite directions, the first worktable and the second worktable can move simultaneously in opposite directions, which improves efficiency.

[0023] (3) The cylinder extends, and its telescopic rod drives the upper pressure riveting head to move downward until it abuts against the workpiece. Since the cylinder body is fixed on the movable column, the cylinder continues to extend, which will drive the movable column to move upward relative to the workpiece, and then drive the lower pressure riveting head located below the workpiece to move upward, so that the lower pressure riveting head will rivet the rivet from below the workpiece to the bottom of the workpiece, thus realizing reverse riveting.

[0034] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0035] Please refer to Figures 1-4 This invention discloses a reverse riveting device capable of dual-station exchange, comprising:

[0036] The riveting assembly 200 includes an upper riveting head 210 movable in the height direction, and a riveting station is provided below the upper riveting head 210;

[0037] A first workbench 300 and a second workbench 400 are used for mounting workpiece 500. The first workbench 300 can move horizontally at a first height to enter or exit the riveting station. The second workbench 400 can move horizontally at a second height and can move vertically to enter or exit the riveting station.

[0038] Specifically, this application sets up a first workbench 300 and a second workbench 400, both of which can be used to install workpieces 500. When one workbench is riveting, the other workbench can perform processes such as changing workpieces 500. The riveting process and the process of changing workpieces 500 are carried out simultaneously, which greatly improves the efficiency of batch riveting.

[0039] After the workpiece 500 on the second workbench 400 is riveted, the second workbench 400 is raised and lowered in the height direction to exit the riveting station. Then the second workbench 400 moves in the horizontal direction to the loading station. At the same time, the first workbench 300 moves in the horizontal direction to the riveting station. At this time, the riveting assembly can rivet the workpiece 500 on the first workbench 300. Meanwhile, the operator or robot can replace the workpiece 500 on the second workbench 400.

[0040] The first worktable 300 moves horizontally at a first height, and the second worktable 400 moves horizontally at a second height, so that the two worktables do not interfere with each other when they move at the same time and can avoid each other.

[0041] Furthermore, it also includes two synchronous pulleys 310 and a synchronous belt 320 simultaneously wound around the two synchronous pulleys 310. The synchronous belt 320 includes a first component 321 on one side of the two synchronous pulleys 310 and a second component 322 on the other side of the two synchronous pulleys 310, and the first component 321 and the second component 322 move in opposite directions.

[0042] The first workbench 300 is connected to the first component 321, and the second workbench 400 is connected to the second component 322.

[0043] Specifically, a timing belt 320 and a timing pulley 310 are provided to connect the first worktable 300 to the first component 321 and the second worktable 400 to the second component 322. Since the first component 321 and the second component 322 can move synchronously in opposite directions, the first worktable 300 and the second worktable 400 can move simultaneously in opposite directions, thus improving efficiency.

[0044] Furthermore, it also includes:

[0045] Mounting bracket 100, on which a first slide rail and a second slide rail are arranged in a horizontal direction, and the first worktable 300 is slidably arranged on the first slide rail;

[0046] A sliding block is slidably mounted on the second slide rail, and a first lead screw is rotatably connected to the sliding block along the height direction, and the first lead screw is threadedly connected to the second worktable 400.

[0047] Specifically, the first lead screw rotates relative to the sliding block, thereby driving the second worktable 400, which is threadedly connected to it, to move along the height direction, thus realizing the lifting and lowering of the second worktable 400.

[0048] Furthermore, the riveting assembly 200 also includes a movable column 230 and a fixed column 220. The movable column 230 can move relative to the fixed column 220 in the height direction. A driving member is provided on the movable column 230, which is used to drive the upper riveting head 210 to move in the height direction.

[0049] A lower rivet head 250 is also provided on the movable column 230, and the lower rivet head 250 is located on the side of the workpiece 500 away from the upper rivet head 210.

[0050] Specifically, the driving component can be a cylinder or a servo motor, etc. If it is a cylinder, when the cylinder extends, its telescopic rod drives the upper pressing head 210 to move downward until it abuts against the workpiece 500; since the cylinder body is fixed on the movable column 230, the continued extension of the cylinder will drive the movable column 230 to move upward relative to the workpiece 500, which in turn drives the lower pressing head 250 located below the workpiece 500 to move upward, so that the lower pressing head 250 rivets the rivet from below the workpiece 500 to the bottom of the workpiece 500, that is, to achieve reverse pressing riveting.

[0051] Furthermore, a balancing cylinder 260 is provided on the fixed column 220. The telescopic rod of the balancing cylinder 260 is connected to the movable column 230 to provide a force to the movable column 230 that is opposite in direction and equal in magnitude to the gravity of the movable column 230.

[0052] A balance cylinder 260 is provided to provide a pulling force to the movable column 230. This pulling force is opposite in direction and equal in magnitude to the weight of the movable column 230. This ensures that when the upper riveting head 210 abuts against the workpiece 500, the driving component continues to extend, and the reaction force on the movable column 230 can drive the movable column 230 to move upward. This avoids the phenomenon that the reaction force is insufficient to overcome the weight of the movable column 230 and thus cannot drive the movable column 230 to move upward.

[0053] Furthermore, the riveting assembly 200 can slide in a direction toward or away from the first worktable 300 or the second worktable 400.

[0054] Furthermore, the reverse riveting device also includes a mounting bracket 100;

[0055] The fixed column 220 is slidably connected to the mounting bracket 100.

[0056] Furthermore, a second lead screw 240 arranged in the horizontal direction is rotatably connected to the mounting bracket 100, and the second lead screw 240 is threadedly connected to the fixed column 220.

[0057] Specifically, the second lead screw 240 rotates relative to the mounting bracket 100, causing the fixed column 220 and the movable column 230, which are threadedly connected to it, to move together in the horizontal direction, so that the second worktable 400 can avoid obstacles during the movement.

[0058] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0059] Furthermore, in this invention, descriptions involving terms such as "first," "second," and "a" are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0060] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0061] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.
