Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to an adaptive guiding clamp. Background Technology

[0002] Fixtures are specialized tooling equipment used in industrial production processes such as machinery manufacturing, processing, and assembly to accurately position and firmly fix workpieces, ensuring that they maintain a preset position and stable posture during subsequent operations and inspections, while also helping to improve operational accuracy, efficiency, and safety.

[0003] In existing technologies, fixtures are essential tooling when processing objects. Fixtures can accurately position the object on the processing table, ensuring that the processing tools can operate stably according to the preset parameters, while reducing damage to the object caused by uneven force. However, when clamping irregular objects, multi-faceted clamps may be used. Multi-faceted clamping is highly complex to adjust, requiring the position of multiple clamping components to be adjusted one by one according to the specific outline of the irregular object, resulting in long clamping preparation time and making it difficult to adapt to the needs of rapid batch processing.

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide an adaptive guiding fixture.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adaptive guiding fixture, including a clamping mechanism, wherein a limiting mechanism is provided on the inner wall of the clamping mechanism, the clamping mechanism includes a processing table, a main frame is provided on the top side of the processing table, the top side of the processing table is slidably connected to the bottom side of the main frame, a semi-circular disk is provided on the inner side of the main frame, the inner side of the main frame is rotatably connected to the outer arc surface of the semi-circular disk, a biting plate is provided on the inner side of one end of the semi-circular disk, and the inner side of one end of the semi-circular disk is rotatably connected to one side end of the biting plate.

[0006] In a preferred embodiment, the limiting mechanism includes a pull rod, one end of which is provided with an insertion rod, the one end of the pull rod being fixedly connected to the one end of the insertion rod, a rectangular plate being provided on the outer side of the insertion rod, the outer side of the insertion rod being engaged with the inner wall of the rectangular plate, and an inclined plate being provided on the outer side of the insertion rod, the outer side of the insertion rod being connected through to the inner wall of the inclined plate.

[0007] In a preferred embodiment, a spring is provided on the inner surface of the main frame, and one end of the spring is fixedly connected to the inner surface of the main frame. A connecting plate is provided on the other end of the spring, and the other end of the spring contacts one side of the connecting plate.

[0008] In a preferred embodiment, one end of the connecting plate is fixedly connected to the middle of the arc surface of the semi-circular disk, and the outer side of the connecting plate is rotatably connected to the inner surface of the main frame.

[0009] In a preferred embodiment, a slider is provided on the bottom side of the main frame, the bottom side of the main frame is fixedly connected to the top side of the slider, and one end of the slider is slidably connected to the inner wall of the processing table.

[0010] In a preferred embodiment, the inner wall of the slider is provided with an inner rod, the inner wall of the slider and the outer side of the inner rod are slidably connected through the slider, and the top end of the inner rod is fixedly connected to the bottom side of the main frame.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. The length is adjusted by the cylinder rod, causing the sliders connected to each main frame to move. By placing an irregular object between the two main frames until the recesses of the three bite plates are in close contact with the surface of the irregular object, the irregular object's surface has unevenness or tilt. When the recesses of the bite plates come into contact with the object's surface, they will be subjected to uneven reaction forces from the object's surface. At this time, the bite plates will automatically rotate slightly in the direction of force balance around their own connecting axis with the semi-circular disk within a rotation range of 30 to 150 degrees, thus enabling them to adapt to the surface of the irregular object. 2. By lowering the ramp so that one end of the ramp aligns with one end of the L-bar, when facing a tall object, in order to clamp it at a stable point, the ramp surface of the ramp contacts one end of the L-bar. As the L-bar is continuously moved, it can generate an upward external force on the ramp, thereby increasing the height of the main frame, and finally making the gripper precisely aligned with the stable clamping position of the object.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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. Example

[0021] like Figures 1-5As shown, this utility model provides a technical solution: an adaptive guiding fixture, including a clamping mechanism 1, a limiting mechanism 2 provided on the inner wall of the clamping mechanism 1, the clamping mechanism 1 including a processing table 11, a main frame 12 provided on the top side of the processing table 11, the top side of the processing table 11 being slidably connected to the bottom side of the main frame 12, a semi-circular disk 13 provided on the inner side of the main frame 12, the inner side of the main frame 12 being rotatably connected to the outer arc surface of the semi-circular disk 13, a bite plate 14 provided on the inner side of one end of the semi-circular disk 13, the inner side of one end of the semi-circular disk 13 being rotatably connected to one side of the bite plate 14, a spring piece 16 provided on the inner surface of the main frame 12, one end of the spring piece 16 being fixedly connected to the inner surface of the main frame 12, a connecting plate 15 provided on the other end of the spring piece 16, the other end of the spring piece 16 contacting one side of the connecting plate 15, the connecting plate One end of the connecting plate 15 is fixedly connected to the middle of the arc surface of the semi-circular disk 13. The outer side of the connecting plate 15 is rotatably connected to the inner surface of the main frame 12. A slider 18 is provided on the bottom side of the main frame 12. The bottom side of the main frame 12 is fixedly connected to the top side of the slider 18. One end of the slider 18 is slidably connected to the inner wall of the processing table 11. An inner rod 19 is provided on the inner wall of the slider 18. The inner wall of the slider 18 is slidably connected to the outer side of the inner rod 19. The top end of the inner rod 19 is fixedly connected to the bottom side of the main frame 12. The inclined surface of the inclined plate 110 is slidably connected to one end of the L rod 112. The top end of the L rod 112 is fixedly connected to the bottom side of the processing table 11. A cylinder rod 17 is provided on one end of the processing table 11. One end of the processing table 11 is fixedly connected to the outer side of the cylinder rod 17. The output end of the cylinder rod 17 is fixedly connected to one side of the slider 18.

[0022] In this embodiment, when the adaptive guide fixture is in use, the machining table 11 is designed with two main frames 12 on its top side. The two main frames 12 are in the same radial direction, and each main frame 12 has a semi-circular disk 13 on its inner side. A connecting plate 15 is installed at the middle of the arc surface of the semi-circular disk 13. The connecting plate 15 is located in the arc-shaped groove on the inner wall of the main frame 12, so the semi-circular disk 13 can rotate from 30 degrees to 150 degrees inside the main frame 12. At one end of the semi-circular disk 13, there are three bite plates 14. Each bite plate 14 has a recess. The bite plates 14 and the semi-circular disk 13 produce the same sound. Thus, the bite plates 14 can rotate at one end of the semi-circular disk 13. The plane rotates from 30 to 150 degrees, and then the length is extended through the cylinder rod 17, causing the sliders 18 connected to the main frame 12 to move. By placing the irregular object between the two main frames 12, until the recesses of the three biting plates 14 are in close contact with the surface of the irregular object, the irregular object surface has unevenness or tilt. When the recesses of the biting plates 14 come into contact with the object surface, they will be subjected to uneven reaction forces from the object surface. At this time, the biting plates 14 will automatically adjust their rotation in the direction of force balance within the rotation range of 30 to 150 degrees around the axis connecting themselves to the semi-circular disk 13, thereby enabling them to adapt to the surface of the irregular object. Two spring clips 16 are installed in the inner arc groove of the main frame 12. The other ends of the two spring clips 16 are in contact with the connecting plate 15. When the connecting plate 15 and the semi-circular disk 13 rotate at an angle, the spring clips 16 under pressure will retract. When the object is no longer clamped, the spring clips 16 use their own restoring ability to synchronously reset the connecting plate 15 and the semi-circular disk 13, so that they are in the positive direction when clamping next time. An inclined plate 110 is designed on the bottom side of the main frame 12, with the top of the inclined plate 110 in contact. A rectangular plate 111 is fixed on the bottom side of the main frame 12, located on the inner wall of the inclined plate 110. By lowering the inclined plate 110, the inclined plate 110 aligns with one end of the L-rod 112. When facing a tall object, in order to clamp it at a stable point, the inclined surface of the inclined plate 110 contacts one end of the L-rod 112. As the L-rod 112 moves continuously, it can generate an upward external force on the inclined plate 110, thereby increasing the height of the main frame 12. Finally, the gripper 14 is precisely aligned with the stable clamping position of the object. An inner rod 19 is installed inside the main frame 12, and a slider 18 passes through the outer side of the inner rod 19, thereby ensuring that the slider 18 and the main frame 12 always maintain a structural connection when the main frame 12 is raised. Example

[0023] like Figures 1-5 As shown, the limiting mechanism 2 includes a pull rod 21, one end of which is provided with an insertion rod 22. One end of the pull rod 21 is fixedly connected to one end of the insertion rod 22. A rectangular plate 111 is provided on the outer side of the insertion rod 22. The outer side of the insertion rod 22 is engaged with the inner wall of the rectangular plate 111. An inclined plate 110 is provided on the outer side of the insertion rod 22. The outer side of the insertion rod 22 is connected through to the inner wall of the inclined plate 110.

[0024] In this embodiment, a pull rod 21 is designed with a plug rod 22 installed at one end. After the inclined plate 110 moves down, the plug rod 22 passes through the hole in the inclined plate 110 and enters the rectangular plate 111, fixing the position of the inclined plate 110 after it moves down. This creates a structural connection between the inclined plate 110 and the rectangular plate 111, preventing the main frame 12 from swaying left and right due to uneven force when it moves upward. This ensures that the main frame 12 always rises steadily in the vertical direction, thereby ensuring that the top gripper 14 of the main frame 12 can accurately align with the stable clamping point of the taller object, maintaining a stable guiding effect and adapting to the clamping requirements of workpieces of different heights.

[0025] Working principle: like Figures 1-5As shown, the length is adjusted by the cylinder rod 17, causing the sliders 18 connected to each of the main frames 12 to move. By placing an irregular object between the two main frames 12 until the recesses of the three gripping plates 14 are in close contact with the surface of the irregular object, the irregular object surface has unevenness or inclination. When the recesses of the gripping plates 14 contact the object surface, they will be subjected to uneven reaction forces from the object surface. At this time, the gripping plates 14 will automatically adjust their rotation in the direction of force balance within a rotatable range of 30 to 150 degrees around the axis connecting themselves to the semi-circular disk 13. This allows them to adapt to the surface of the irregular object. By lowering the inclined plate 110, the inclined plate 110 is aligned with one end of the L rod 112. When facing a tall object, in order to clamp it at a stable point, the inclined surface of the inclined plate 110 contacts one end of the L rod 112. As the L rod 112 moves continuously, it can generate an upward external force on the inclined plate 110, thereby increasing the height of the main frame 12 to ensure that the clamped point of the object is in a stable state. By inserting the rod 22 through the hole in the inclined plate 110 and into the rectangular plate 111, the position of the inclined plate 110 is fixed after it moves down, thus creating a structural connection between the inclined plate 110 and the rectangular plate 111. This prevents the main frame 12 from swaying left and right due to uneven force when it moves upward, ensuring that the main frame 12 always rises steadily in the vertical direction. This, in turn, ensures that the top gripper 14 of the main frame 12 can be accurately aligned with the stable clamping point of the taller object.

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.
