Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a robotic welding positioner tooling. Background Technology

[0002] In modern manufacturing, especially in automobile manufacturing, construction machinery, and aerospace, welding is a critical processing technology whose quality and efficiency directly affect product performance and production efficiency. Traditional manual welding methods suffer from high labor intensity, low production efficiency, and poor weld quality stability, making it difficult to meet the demands of large-scale, high-precision production. Therefore, robotic welding technology has emerged. With its automation, high precision, and high efficiency, robotic welding significantly improves the stability and consistency of welding operations, effectively reducing labor costs and intensity.

[0003] However, in existing technologies, when welding workpieces with complex structures and irregular shapes, robot welding with a single fixed posture has limitations such as many welding dead angles and poor accessibility, making it difficult to achieve all-round welding. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a robotic welding positioner tooling.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a robotic welding positioner tooling, including a base frame and a mounting base. A Y-axis rotation mechanism is fixedly connected to the upper side of the mounting base, and a Z-axis rotation mechanism is movably connected to one side of the Y-axis rotation mechanism. A clamping mechanism is movably connected to the upper side of the Z-axis rotation mechanism. The Y-axis rotation mechanism and the Z-axis rotation mechanism have the same motion principle. The Y-axis rotation mechanism includes a side frame, a first servo motor, an outer ring, a gear, balls, an internal gear ring, a side cover, and a connecting frame. The connecting frame is fixedly connected to one side of the side cover. The side cover is fixedly connected to the internal gear ring. The internal gear ring rotates inside the outer ring through multiple sets of balls. The outer ring is fixedly connected to the side of the side frame, and the gear meshes inside the internal gear ring.

[0006] Preferably, the gear is fixedly connected to the output shaft of the first servo motor, and the first servo motor is fixedly connected to the inner side of the side frame.

[0007] Preferably, both the outer ring surface of the internal toothed ring and the inner ring surface of the outer ring are provided with ring grooves to accommodate the balls.

[0008] Preferably, the clamping mechanism includes a disc and multiple sets of single clamping assemblies, which are arranged and fixed around the upper side of the disc.

[0009] Preferably, the single clamp assembly includes a fastening bolt, a side claw, and a side block, with a raceway groove in the middle of the side block.

[0010] Preferably, the middle shaft of the side claw is movably connected inside the runway groove, and the fastening bolt is threadedly connected to the end of the side claw.

[0011] Preferably, the lower end of the fastening bolt rests against the upper side of the disc.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, after the clamping mechanism clamps the workpiece to be welded, the first servo motor is started and drives the gear to rotate. The gear meshes with the inner teeth of the inner gear ring. With multiple sets of balls embedded between the outer ring groove of the inner gear ring and the inner ring groove of the outer ring, the inner gear ring rotates in the middle of the outer ring after being stressed, and drives the side cover and connecting frame to rotate. This drives the Z-axis rotation mechanism, the clamping mechanism and the workpiece to be welded to rotate in a straight line parallel to the Y-axis. The Z-axis rotation mechanism and the Y-axis rotation mechanism operate in the same way, driving the clamping mechanism and the workpiece to be welded to rotate in a straight line parallel to the Z-axis. In conjunction with the welding robot, welding dead angles are avoided, and welding of complex or irregular shaped workpieces can be achieved.

[0014] 2. In this utility model, the distribution of multiple sets of single clamping components is customized according to the shape of the object to be welded. The object to be welded is placed in the middle of the upper side of the disc and in the middle of the multiple sets of single clamping components. The side claws are pushed inward, and the middle shaft slides in the raceway groove until the highest point of the side claws abuts against the object to be welded. The fastening bolts are tightened with a wrench. After the multiple sets of single clamping components are operated in sequence, the multiple sets of side claws flip and clamp the object to be welded, ensuring that the object to be welded remains in a stable state afterward, thereby ensuring the welding quality.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a robotic welding positioner fixture, including a base frame 1 and a mounting base 2. A Y-axis rotation mechanism 3 is fixedly connected to the upper side of the mounting base 2, and a Z-axis rotation mechanism 4 is movably connected to one side of the Y-axis rotation mechanism 3. A clamping mechanism 5 is movably connected to the upper side of the Z-axis rotation mechanism 4. The Y-axis rotation mechanism 3 and the Z-axis rotation mechanism 4 have the same motion principle. The Y-axis rotation mechanism 3 includes a side frame 31, a first servo motor 32, an outer ring 33, a gear 34, a ball bearing 35, an internal gear ring 36, a side cover 37, and... A connecting frame 38 is fixedly connected to one side of the side cover 37. The side cover 37 is fixedly connected to the internal gear ring 36. The internal gear ring 36 rotates inside the outer ring 33 via multiple sets of balls 35. The outer ring 33 is fixedly connected to the side of the side frame 31. A gear 34 meshes inside the internal gear ring 36. The gear 34 is fixedly connected to the output shaft of the first servo motor 32. The first servo motor 32 is fixedly connected to the inside of the side frame 31. The outer ring surface of the internal gear ring 36 and the inner ring surface of the outer ring 33 are both provided with annular grooves to accommodate the balls 35.

[0023] The specific settings and functions of this embodiment are described below: After the clamping mechanism 5 clamps the workpiece to be welded, the first servo motor 32 is started and drives the gear 34 to rotate. The gear 34 meshes with the inner teeth of the inner gear ring 36. With multiple sets of balls 35 embedded between the outer ring groove of the inner gear ring 36 and the inner ring groove of the outer ring 33, the inner gear ring 36 rotates in the middle of the outer ring 33 after being stressed, and drives the side cover 37 and the connecting frame 38 to rotate. This drives the Z-axis rotation mechanism 4, the clamping mechanism 5 and the workpiece to be welded to rotate around a straight line parallel to the Y-axis. The Z-axis rotation mechanism 4 and the Y-axis rotation mechanism 3 have the same operating principle and the same structure, only the size is different. The Z-axis rotation mechanism 4 and the Y-axis rotation mechanism 3 operate in the same way, driving the clamping mechanism 5 and the workpiece to be welded to rotate around a straight line parallel to the Z-axis. In conjunction with the welding robot, welding dead angles are avoided, and welding of complex or irregular shaped workpieces is realized.

[0024] Example 2: Figure 1 - Figure 4 As shown, the clamping mechanism 5 includes a disc 51 and multiple sets of single clamping assemblies. The multiple sets of single clamping assemblies are distributed and fixed around the upper side of the disc 51. Each single clamping assembly includes a fastening bolt 52, a side claw 53, and a side block 54. A racetrack groove 55 is provided in the middle of the side block 54. The middle part of the side claw 53 is movably connected to the inside of the racetrack groove 55. The fastening bolt 52 is threaded to the end of the side claw 53. The lower end of the fastening bolt 52 abuts against the upper side of the disc 51.

[0025] The overall effect of this embodiment is that, according to the shape of the object to be welded, the positions of multiple sets of single clamping components are customized. The object to be welded is placed in the middle of the upper side of the disc 51 and in the middle position of the multiple sets of single clamping components. In the initial state, the central axis of the side claw 53 is located at the farthest inner edge of the runway groove 55. The side claw 53 is pushed inward, and its central axis slides in the runway groove 55 until the highest point of the side claw 53 abuts against the object to be welded. Then, the fastening bolt 52 is tightened with a wrench. After the fastening bolt 52 rotates at the lowest end of the side claw 53, it abuts against the disc 51. After the multiple sets of single clamping components are operated in sequence, the multiple sets of side claws 53 flip and clamp the object to be welded, ensuring that the object to be welded remains in a stable state of flipping afterward, thereby ensuring the welding quality.

[0026] The usage and working principle of this device are as follows: The clamping mechanism 5 is movably mounted on the upper part of the Z-axis rotating mechanism 4, and the Z-axis rotating mechanism 4 is movably mounted on the side of the Y-axis rotating mechanism 3. The Y-axis rotating mechanism 3 is fixed to the base frame 1 by the mounting seat 2. The base frame 1 is mounted on the carrier. The object to be welded is placed in the middle of the upper side of the disc 51 and is positioned in the middle of the multiple sets of single clamping components. In the initial state, the middle shaft of the side claw 53 is located at the farthest inner edge of the runway groove 55. Pushing the side claw 53 inward causes its middle shaft to slide in the runway groove 55 until the highest point of the side claw 53 abuts against the object to be welded. Then, tighten the fastening bolt 52 with a wrench. After the fastening bolt 52 rotates at the lowest end of the side claw 53, it abuts against the disc 51. After the multiple sets of single clamping components are operated in sequence, the multiple sets of side claws 53 flip and clamp the object to be welded. The Z-axis rotation mechanism 4 and the Y-axis rotation mechanism 3 operate on the same principle and have the same structure, differing only in size. The first servo motor 32 is started and drives the gear 34 to rotate. The gear 34 meshes with the inner teeth of the inner gear ring 36. Multiple sets of balls 35 are embedded between the outer ring groove of the inner gear ring 36 and the inner ring groove of the outer ring 33, causing the inner gear ring 36 to rotate in the middle of the outer ring 33 after being stressed. This drives the side cover 37 and the connecting frame 38 to rotate, thereby driving the Z-axis rotation mechanism 4, the clamping mechanism 5, and the workpiece to be welded to rotate around a straight line parallel to the Y-axis. The Z-axis rotation mechanism 4 and the Y-axis rotation mechanism 3 operate in the same way, driving the clamping mechanism 5 and the workpiece to be welded to rotate around a straight line parallel to the Z-axis. Together with the welding robot, this enables the welding of complex or irregularly shaped workpieces.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
