Technical Field
[0001] This utility model relates to the field of mechanical parts processing and assembly technology, specifically a multi-point positioning and clamping device for intelligent robots. Background Technology
[0002] In the field of machining, manufacturing, and assembly technology, especially in the automotive, shipbuilding, and aerospace industries, production lines often require positioning and clamping of automotive body parts for further processing, riveting, welding, and other operations. For many irregularly shaped parts, it is often necessary to design and manufacture dedicated positioning and clamping devices, and use clamping units or cylinders to position and clamp the workpiece in multiple positions.
[0003] Chinese utility model patent application number 202420316250.5 discloses a multi-point positioning and clamping device for intelligent robots. The housing is mechanically connected to a frame via a bracket. A cylinder and a positioning seat are mechanically connected to the housing. A linkage assembly is placed within the cavity formed by the positioning seat and the housing and is driven by the cylinder to achieve the clamping or releasing action of the linkage assembly on the workpiece. This utility model achieves automatic pick-and-place, multi-point positioning, and workpiece clamping by using multiple positioning and clamping mechanisms. It offers good interchangeability, fast response speed, and rapid turnover. The use of sensors improves safety and automation.
[0004] However, during the use of the aforementioned equipment, it was found that the positioning and clamping devices are all mounted on the frame. The fixed structure of the frame results in a relatively fixed position for the positioning and clamping mechanism, making it difficult to flexibly adjust according to the different positions of the workpiece positioning holes. When the workpiece model or the position of the positioning hole changes, the existing mechanism cannot accurately correspond to the new positioning hole, requiring adjustments to the frame or the mechanism itself. Adapting to different specifications of workpieces is costly and inefficient. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a multi-point positioning and clamping device for intelligent robots, which solves the problem mentioned in the background technology that the fixed structure of the frame leads to a relatively fixed position of the positioning and clamping mechanism, making it difficult to flexibly adjust according to the different positions of the workpiece positioning holes.

The rotating component includes a rotating frame, one end of which has a rotating arm fixedly mounted. The rotating arm is located in the rotating groove and rotatably mounted on the rotating shaft. A worm wheel is mounted on the rotating arm, and the worm wheel meshes with the worm gear.
[0007] Preferably, a connecting seat is fixedly provided at the bottom of the rotating groove, and the connecting seat can be detachably mechanically connected to the robotic arm of the intelligent robot.

[0012] This utility model provides a multi-point positioning and clamping device for intelligent robots. It has the following features:
[0013] Beneficial effects:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1:
[0023] Please see Figures 1-4This utility model provides a multi-point positioning and clamping device for intelligent robots, including a frame assembly 1 and a mounting base 2. A positioning and clamping mechanism is installed on the mounting base 2. The frame assembly 1 is composed of a fixed assembly 11 and a rotating assembly 12. The mounting base 2 is installed in both the fixed assembly 11 and the rotating assembly 12. The fixed assembly 11 includes a fixed frame 111. A rotating groove 112 is opened at one end of the fixed frame 111. A rotating shaft 113 is vertically fixed in the rotating groove 112. A worm gear 117 is rotatably installed at the end of the fixed frame 111 near the rotating groove 112. The worm gear 117 is connected to a first motor 116. The rotating assembly 12 includes a rotating frame 121. A rotating arm 123 is fixedly installed at one end of the rotating frame 121. The rotating arm 123 is located in the rotating groove 112 and is rotatably mounted on the rotating shaft 113. A worm wheel 124 is provided on the rotating arm 123. The worm wheel 124 meshes with the worm gear 117.
[0024] A connecting seat 118 is fixedly provided at the bottom of the rotating groove 112. The connecting seat 118 can be detachably mechanically connected to the robotic arm of the intelligent robot.
[0025] The fixed frame 111 also has a first movable groove 114, in which a first threaded rod 1142 is rotatably installed. The first threaded rod 1142 is connected to the output end of the second motor 115, and the mounting base 2 is screwed to the first threaded rod 1142.
[0026] The first threaded rod 1142 has a first slide rod 1141 arranged parallel to both sides. The first slide rod 1141 is fixedly installed in the first moving groove 114, and the mounting seat 2 is slidably installed on the first slide rod 1141.
[0027] The rotating frame 121 has a second moving groove 122, in which a second threaded rod 1222 is rotatably installed. The second threaded rod 1222 is connected to the output end of the third motor 125, and the second threaded rod 1222 is screwed to the mounting base 2.
[0028] The second threaded rod 1222 has two parallel sliding rods 1221 on both sides. The second sliding rods 1221 are fixedly installed in the second moving groove 122, and the mounting seat 2 is slidably installed on the second sliding rods 1221.
[0029] Specifically, the frame assembly 1 consists of a fixed assembly 11 and a rotating assembly 12. When the first motor 116 is working, it can drive the worm gear 117 to rotate the worm wheel 124, causing the rotating arm 123 to rotate around the rotating shaft 113, thereby driving the rotating frame 121 and the mounting base 2 and positioning clamping mechanism above to change their angles, flexibly adapting to the needs of the workpiece positioning hole at different angle positions, and solving the problem that the angle cannot be adjusted under the fixed structure.
[0030] When the second motor 115 is working, it can drive the first threaded rod 1142 to rotate, causing the mounting base 2 to move linearly along the first slide rod 1141 in the first moving groove 114, so that the positioning and clamping mechanism on the fixed assembly 11 can adjust its position along the direction of the fixed frame 111. When the third motor 125 is working, it can drive the second threaded rod 1222 to rotate, causing the mounting base 2 to move linearly along the second slide rod 1221 in the second moving groove 122, so that the positioning and clamping mechanism on the rotating assembly 12 can adjust its position along the direction of the rotating frame 121, adapting to the positioning of workpieces at different positions in this direction.
[0031] The combination of linear adjustment of the fixed component 11 and angle adjustment of the rotating component 12 enables the positioning and clamping mechanisms on the two sets of mounting seats 2 to flexibly adjust their positions in multiple angles and directions. No matter how the position of the workpiece positioning hole changes, precise docking can be achieved through the synergistic effect of the above structures. There is no need to modify the entire frame, which significantly reduces the cost of adapting to different workpieces, improves adjustment efficiency, and fundamentally solves the problem of rigid positioning mechanism caused by the fixed frame.
[0032] The connecting seat 118 at the bottom of the rotating slot 112 can be detachably connected to the robotic arm of the intelligent robot, allowing the entire equipment to move under the drive of the intelligent robot. Combined with its own multi-dimensional adjustment function, it forms a more comprehensive position adjustment system. The intelligent robot can drive the entire equipment closer to workpieces in different positions, and then complete the precise matching of the positioning and clamping mechanism and the positioning hole through the equipment's own adjustment structure, further enhancing its ability to meet the positioning needs of complex workpieces.
[0033] Working principle: The intelligent robot moves the entire equipment to the vicinity of the workpiece to be processed. If the angle of the rotating component 12 needs to be adjusted, the first motor 116 is started, which drives the worm gear 117 to rotate. The worm gear 117 drives the worm wheel 124 meshing with it to rotate, causing the rotating arm 123 to rotate around the rotating shaft 113. This, in turn, drives the rotating frame 121 and the mounting base 2 and the positioning and clamping mechanism above it to adjust to a suitable angle to match the angle position of the workpiece positioning hole.
[0034] When it is necessary to adjust the linear position of the positioning and clamping mechanism on the fixed assembly 11, the second motor 115 is started. The second motor 115 drives the first threaded rod 1142 to rotate. The mounting seat 2, which is helically connected to the first threaded rod 1142, moves along the first slide rod 1141 in the first moving groove 114 until the positioning and clamping mechanism on the fixed assembly 11 reaches the position of the corresponding workpiece positioning hole. If it is necessary to adjust the linear position of the positioning and clamping mechanism on the rotating assembly 12, the third motor 125 is started. The third motor 125 drives the second threaded rod 1222 to rotate. The mounting seat 2, which is helically connected to the second threaded rod 1222, moves along the second slide rod 1221 in the second moving groove 122, so that the positioning and clamping mechanism on the rotating assembly 12 accurately aligns with the corresponding workpiece positioning hole.
[0035] After the positioning and clamping mechanisms on the two sets of mounting bases 2 complete the precise alignment with the workpiece positioning holes, they can perform the positioning and clamping operations on the workpiece. After the operation is completed, each motor operates in reverse, driving the relevant components to reset, and the intelligent robot takes the equipment away from the workpiece, completing one work cycle.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
