Description

Technical Field

[0001] This utility model relates to the field of positioner technology, and more specifically, to a shockproof and buffered industrial robot positioner. Background Technology

[0002] Industrial robot positioners are important equipment that assist industrial robots in their work. They are automated rotating devices that change the orientation of products through rotary motion. They are usually used in conjunction with robotic arms to position products in ideal processing positions and postures, thereby improving production efficiency and processing quality.

[0003] Industrial robot positioners are classified into single-axis positioners, dual-axis positioners, three-axis positioners, and composite positioners according to the number of drive motors. Among them, dual-axis positioners, such as side-mounted positioners and rotary positioners, can make the workpiece rotate around two axes. They are suitable for more complex workpieces and processing requirements. They are mainly composed of a rotary axis, a flipping axis, and a mechanical frame. They are generally driven by external axes of welding robots and can place any weld seam in a horizontal or boat-shaped welding position. They are usually used for welding multi-faceted workpieces.

[0004] Existing industrial robot positioners, such as dual-axis positioners, have the following drawbacks: to ensure that the dual-axis positioner can rotate flexibly in both axes, it generally uses single-end load drive. The two axes of the dual-axis positioner simultaneously bear the weight of the workpiece on one end, and during movement, it is prone to large vibrations due to shaking or inertial impact, which reduces the service life of the equipment. Therefore, in order to solve the above technical problems, this application proposes a shock-absorbing industrial robot positioner. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a shockproof and buffered industrial robot positioner to solve the technical problems of existing industrial robot positioners that bear the weight of the workpiece at one end, have large vibrations during use, and have a short service life.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shock-absorbing and buffering industrial robot positioner, including a dual-axis positioner, wherein the dual-axis positioner includes a first rotary disk assembly and a second rotary disk assembly;

[0007] The third frame includes a base frame, on the top of which is an arc-shaped slide block. An arc-shaped slide groove is formed at the inner arc end of the arc-shaped slide block. Both the arc-shaped slide block and the arc-shaped slide groove are concentric with the first rotating disk assembly.

[0008] An L-shaped frame is fixed at the corresponding position on the outer side wall of the second rotating disk assembly. A first rotating component is installed on the outer side wall and is rotatably connected to the outer side wall of the base frame through the first rotating component. The first rotating component is concentric with the first rotating disk assembly. A second rotating component is installed on the top of the inner side wall of the L-shaped frame. The second rotating component is concentric with the second rotating disk assembly.

[0009] The sliding component is installed on the outer wall of the L-shaped frame and can be matched with the arc-shaped sliding groove.

[0010] Preferably, the dual-axis positioner further includes a first frame, a first drive box is installed at one top end of the first frame, a first rotary disk assembly is connected to the power output end of the first drive box, a second frame is connected to the power output end of the first rotary disk assembly, a second drive box is installed on the outer side wall of the second frame, and a second rotary disk assembly is connected to the power output end of the second drive box.

[0011] Preferably, the structure of the first rotating component is the same as that of the second rotating component, both including a rotating sleeve, with a rotating core rotatably mounted on the inner sidewall of the rotating sleeve, and a disc spring connected in contact between the end of the rotating core and the inner sidewall of the rotating sleeve.

[0012] Preferably, the outer wall of the rotating core is provided with an annular groove, and the inner wall of the annular groove is rotatably connected with a ball bearing, which is rotatably connected to the inner wall of the rotating sleeve.

[0013] Preferably, the sliding member includes a connecting rod fixed to the top of the L-shaped frame, a universal ball seat is mounted on the top of the connecting rod, and a universal ball is rotatably mounted on the top of the universal ball seat.

[0014] Preferably, a lifting drive assembly is installed at the bottom of the second rotating assembly, and a gripper is installed at the bottom of the lifting drive assembly.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention features a third frame positioned opposite the first rotary disk assembly, with an L-shaped frame rotatably connected to the corresponding part of the third frame. This allows the L-shaped frame and the first rotary disk assembly to rotate around the same center. The L-shaped frame also has grippers rotatably mounted concentrically with the second rotary disk assembly. Furthermore, a sliding component that engages with the arc groove of the arc-shaped slide block is installed outside the L-shaped frame. This design achieves dual-axis load-bearing without affecting the rotation of both axes of the dual-axis positioner, simultaneously supporting the weight of the workpiece at both ends.

[0027] like Figure 1-4As shown, this utility model provides a shock-absorbing industrial robot positioner, including a dual-axis positioner 1. The dual-axis positioner 1 includes a first rotary disk assembly 103 and a second rotary disk assembly 106. The dual-axis positioner 1 also includes a first frame 101. A first drive box 102 is installed at one end of the top of the first frame 101. The power output end of the first drive box 102 is connected to the first rotary disk assembly 103. The power output end of the first rotary disk assembly 103 is connected to a second frame 104. A second drive box 105 is installed on the outer wall of the second frame 104. The power output end of 5 is connected to the second rotary disk assembly 106. The dual-axis positioner 1 adopts an existing product. The first frame 101 provides stable support for the overall structure. The first drive box 102 can drive the first rotary disk assembly 103 to rotate horizontally around the axis. The power output end of the first rotary disk assembly 103 is connected to the second frame 104. The second drive box 105 is installed on the outer wall of the second frame 104. The second drive box 105 can drive the second rotary disk assembly 106 to rotate vertically, thereby realizing the angle adjustment of the workpiece in the horizontal and vertical directions.

[0028] The third frame 2 includes a base frame 201. An arc-shaped slide block 202 is installed on the top of the base frame 201. An arc-shaped groove 203 is opened at the inner arc end of the arc-shaped slide block 202. The arc-shaped slide block 202 and the arc-shaped groove 203 are both concentric with the first rotating disk assembly 103, providing guidance and support for the movement of the L-shaped frame 4. The arc-shaped slide block 202 and the arc-shaped groove 203 can also be annular, and are also concentric with the first rotating disk assembly 103.

[0029] The L-shaped frame 4 is fixed to the corresponding position on the outer side wall of the second rotating disk assembly 106. A first rotating component 3 is installed on the outer side wall and is rotatably connected to the outer side wall of the base frame 201 via the first rotating component 3. The first rotating component 3 is concentric with the first rotating disk assembly 103. A second rotating component 6 is installed on the top of the inner side wall of the L-shaped frame 4, and the second rotating component 6 is concentric with the second rotating disk assembly 106. The L-shaped frame 4 serves a connecting and transmission function, and is rotatably connected to the base frame 201 via the first rotating component 3. On the outer side wall, the rotation axis of the first rotating component 3 is concentric with the first rotating disk assembly 103, ensuring that the L-shaped frame 4 can rotate synchronously with the first rotating disk assembly 103 around the same center, achieving double-end force. The top of the inner side wall of the L-shaped frame 4 is equipped with a second rotating component 6, the rotation axis of the second rotating component 6 is concentric with the second rotating disk assembly 106, achieving double-end clamping of the workpiece without hindering the rotation of the second rotating disk assembly 106. In addition, a sliding component 5 is installed on the outer side wall of the L-shaped frame 4, which is used to cooperate with the arc groove 203 to make the L-shaped frame 4 rotate more smoothly and further reduce vibration during movement.

[0030] The sliding member 5 is installed on the outer wall of the L-shaped frame 4 and can cooperate with the arc-shaped slide groove 203. The sliding member 5 includes a connecting rod 501 fixed to the top of the L-shaped frame 4, a universal ball seat 502 installed on the top of the connecting rod 501, and a universal ball 503 rotatably mounted on the top of the universal ball seat 502. Specifically, the sliding member 5 includes a connecting rod 501 fixed to the top of the L-shaped frame 4, a universal ball seat 502 installed on the top of the connecting rod 501, and a universal ball 503 that can flexibly rotate on the top of the universal ball seat 502. The universal ball 503 contacts the arc-shaped slide groove 203, which reduces the friction between the sliding member 5 and the arc-shaped slide groove 203 while ensuring that the L-shaped frame 4 rotates with the first rotating disk assembly 103.

[0031] Furthermore, the structure of the first rotating component 3 is the same as that of the second rotating component 6, both including a rotating sleeve 301. A rotating core 303 is rotatably mounted on the inner wall of the rotating sleeve 301. A disc spring 302 is connected between the end of the rotating core 303 and the inner wall of the rotating sleeve 301. An annular groove 304 is formed on the outer wall of the rotating core 303. A ball bearing 305 is rotatably connected to the inner wall of the rotating sleeve 301. When the rotating core 303 is subjected to force and rotates, the disc spring 302 absorbs vibration energy and plays a buffering and shock-absorbing role. The ball bearing 305 is installed in the annular groove 304 formed on the outer wall of the rotating core 303. The ball bearing 305 is in contact with the inner wall of the rotating sleeve 301 and can rotate flexibly, converting sliding friction into rolling friction, effectively reducing rotational resistance, improving rotational accuracy and efficiency, and reducing component wear.

[0032] Furthermore, a lifting drive assembly 7 is installed at the bottom of the second rotating assembly 6, and a gripper 8 is installed at the bottom of the lifting drive assembly 7. The lifting drive assembly 7 can be driven by existing electric push rods, cylinders, etc., to achieve vertical lifting movement. The gripper 8 installed at the bottom of the lifting drive assembly 7 is used to grip and fix the workpiece.

[0033] Working principle: This utility model sets a third frame 2 at the opposite end of the first rotating disk assembly 103 and rotatably connects an L-shaped frame 4 at the corresponding position of the third frame 2, so that the L-shaped frame 4 and the first rotating disk assembly 103 rotate around the same center.

[0034] During operation, the first drive box 102 of the existing dual-axis positioner 1 drives the first rotary disk assembly 103 to rotate, which in turn drives the second frame 104, the second drive box 105 and the second rotary disk assembly 106 to move, realizing the rotation of the workpiece in the horizontal direction. Since the first rotating component 3 and the first rotary disk assembly 103 are concentrically set, the L-shaped frame 4 will follow the first rotary disk assembly 103 to rotate synchronously around the same center, realizing double-end clamping.

[0035] Furthermore, the L-shaped frame 4 is rotatably mounted with grippers 8 concentrically arranged with the second rotary disk assembly 106. The L-shaped frame 4 is also equipped with sliding parts 5 that can mate with the arc-shaped slide groove 203 of the arc-shaped slide block 202. This design allows for dual-end loading and simultaneous bearing of the workpiece weight without affecting the rotation of the two axes of the dual-axis positioner 1. This reduces vibrations caused by shaking or inertial impacts during movement, increases the service life of the equipment, and provides excellent shock absorption performance.

[0036] The second rotating component 6 is concentric with the second rotating disk assembly 106, so that the gripper 8 installed at the bottom of the second rotating component 6 can rotate synchronously with the second rotating disk assembly 106 around the same center while cooperating with the second rotating disk assembly 106 to grip the workpiece under double-end force.

[0037] During the rotation of the L-shaped frame 4, the sliding member 5 slides in the arc groove 203. The universal ball seat 502 installed on the top of the connecting rod 501, and the universal ball 503 that can rotate flexibly on the top of the universal ball seat 502, the universal ball 503 contacts the arc groove 203, while ensuring that the L-shaped frame 4 follows the rotation of the first rotating disk assembly 103, reducing the friction between the sliding member 5 and the arc groove 203.

[0038] When the equipment shakes or is subjected to inertial impact during operation, the disc springs 302 in the first rotating component 3 and the second rotating component 6 are quickly compressed and deformed to absorb vibration energy and reduce the impact on the equipment. The ball bearings 305 reduce rotational resistance and avoid additional vibration due to friction, effectively reducing equipment vibration, extending equipment service life, and improving overall shock absorption performance (the dual-axis positioner 1, lifting drive component 7, and gripper 8 are all existing products on the market and are all connected to external power supply and external switch).

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
