Description

Technical Field

[0001] This application relates to the field of jigs, and more specifically to a rotatable and tiltable jig. Background Technology

[0002] In industrial fields such as machining, inspection, assembly, and welding, jigs are widely used to precisely fix and position workpieces to ensure machining accuracy, improve production efficiency, and enhance operational safety. Generally, for structural stability, rigidity, and design simplification, jigs are fixed to the machine tool. However, this fixed setup lacks flexibility when facing workpiece position changes, multi-angle machining, or inspection requirements, resulting in poor adaptability and difficulty in meeting complex and ever-changing machining demands. Utility Model Content

[0003] In view of this, this application provides a rotatable and tiltable jig to improve adaptability.

[0004] A rotatable and tiltable fixture includes a flipping assembly and a rotating assembly. The flipping assembly includes a first base plate and a second base plate, one end of the second base plate being rotatably connected to the first base plate. The rotating assembly is rotatably disposed on the second base plate and includes a first base and a second base. The first base is rotatably disposed on the side of the second base plate opposite to the first base plate, and the second base is connected to the first base. The second base includes a limiting mechanism for positioning a workpiece.

[0005] In some possible implementations, the flipping assembly further includes a flipping shaft seat and a flipping shaft. The flipping shaft seat includes a flipping shaft mounting plate and a flipping bearing carrier plate connected to the flipping shaft mounting plate. One end of the flipping shaft mounting plate away from the flipping bearing carrier plate is connected to the first base plate. One end of the flipping shaft is connected to the end of the flipping bearing carrier plate away from the flipping shaft mounting plate. The second base plate is provided with a rotating hole, and the other end of the flipping shaft is rotatably inserted into the rotating hole.

[0006] In some possible implementations, the flipping assembly further includes a bracing assembly, which includes a guide rail and a connecting rod. The guide rail is disposed on the first base plate, and one end of the connecting rod is slidably disposed on the guide rail, while the other end is rotatably connected to the second base plate.

[0007] In some possible implementations, the linkage includes a first link, a second link, a first slider, a second slider, and an elastic element. The first slider and the second slider are both movably disposed on the guide rail. The elastic element is disposed between the first slider and the second slider. One end of the first link is rotatably connected to the second base plate, and the other end is rotatably connected to the first slider. One end of the second link is rotatably connected to the second slider, and the other end is rotatably connected to the first link.

[0008] In some possible implementations, the flipping assembly further includes a flipping limiter disposed on the first base plate, the flipping limiter including a movable stop block that can be movably inserted between the first slider and the second slider.

[0009] In some possible implementations, the rotating assembly includes a bearing and a rotating shaft, the second base plate is provided with a through hole, the bearing is located on the side of the second base plate opposite to the first base, one end of the rotating shaft is located on the bearing, and the other end passes through the through hole and is connected to the first base.

[0010] In some possible implementations, the rotating assembly further includes a bearing mounting base and a shaft mounting base. The bearing mounting base is fixedly connected to the side of the second base plate opposite to the first base. The bearing is disposed in the bearing mounting base. The shaft mounting base is fixedly connected to the bearing mounting base. One end of the rotating shaft is rotatably inserted into the shaft mounting base.

[0011] In some possible implementations, the rotating assembly further includes a limiting pin, the first base having a plurality of first insertion holes, and the second base having a plurality of second insertion holes, the limiting pin being used to insert into the first insertion holes and the second insertion holes.

[0013] In some possible implementations, the fixture further includes a buffer disposed between the first base plate and the second base plate.

[0014] In this application, the rotating component drives the flipping component to achieve forward and reverse rotation, while the rotating component independently drives the workpiece to achieve forward and reverse rotation. This allows the workpiece to achieve precise positioning with two degrees of freedom in space, including arbitrary tilt angle and rotational posture.

Detailed Implementation

[0022] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0023] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that allows communication between the two; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication between two elements or the interaction between two elements. In the description of this application, it should be noted that "multiple" means two or more, unless otherwise expressly and specifically limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0024] The embodiments of this case will be described in detail below with reference to the accompanying drawings.

[0025] Please see Figure 1 One embodiment of this application provides a rotatable and tiltable jig 100 (hereinafter referred to as jig 100) for securely clamping a mobile phone case 200 and for conveniently adjusting its rotation angle and tilt posture to adapt to the requirements of different processes such as grinding, inspection, spraying, or assembly for the observation and operation angle of the workpiece. In other embodiments, the jig 100 can also be used to clamp and position other precision small workpieces with similar requirements, such as electronic component housings, precision parts, or small molds. The rotation and tilting functions of the jig 100 help to improve the adaptability and ease of operation of the jig 100.

[0026] Please see Figure 1 , Figure 2 and Figure 3 The fixture 100 includes a flipping component 10 and a rotating component 20. The rotating component 20 is connected to the flipping component 10. The flipping component 10 is used to drive the rotating component 20 to rotate around a first direction A or the opposite direction of the first direction A. The rotating component 20 is used to drive the phone case 200 to rotate around a second direction B or the opposite direction of the second direction B.

[0027] The flipping assembly 10 includes a first base plate 11 and a second base plate 12, with one end of the second base plate 12 rotatably connected to the first base plate 11. The rotating assembly 20 is rotatably mounted on the second base plate 12 and includes a first base 21 and a second base 22. The first base 21 is rotatably mounted on the side of the second base plate 12 opposite to the first base plate 11, and the second base 22 is connected to the first base 21. The second base 22 includes a limiting mechanism for positioning the workpiece.

[0028] In this application, the flipping component 10 drives the rotating component 20 to achieve forward and reverse rotation around the first direction A. At the same time, the rotating component 20 independently drives the workpiece to achieve forward and reverse rotation around the second direction B. This allows the workpiece to achieve precise positioning with two degrees of freedom in space, with any tilt angle and rotational posture. This significantly improves the processing, inspection or assembly efficiency of workpieces with complex curved surfaces or requiring multi-faceted operations (such as mobile phone case 200), and ensures the stability and consistency of workpiece positioning during the transition between processes.

[0029] Please see Figure 2 and Figure 4 In this embodiment, the flipping assembly 10 further includes a flipping shaft seat 13 and a flipping shaft 14. The flipping shaft seat 13 is generally L-shaped and includes a flipping shaft mounting plate 131 and a flipping bearing carrier plate 132 vertically connected to the flipping shaft mounting plate 131. One end of the flipping shaft mounting plate 131 away from the flipping bearing carrier plate 132 is connected to the first base plate 11 by fasteners (e.g., screws). One end of the flipping shaft 14 is vertically connected to the end of the flipping bearing carrier plate 132 away from the flipping shaft mounting plate 131 by welding. The other end of the flipping shaft 14 is rotatably inserted into a rotating hole provided in the second base plate 12. In this way, the second base plate 12 can rotate relative to the first base plate 11 about the flipping shaft 14, thereby driving the rotating assembly 20 provided on the second base plate 12 to rotate.

[0030] Furthermore, there are two flip-axis seats 13 and two flip-axis 14. Each flip-axis seat 13 is connected to one flip-axis 14. A rotating hole is provided on each side of the first base plate 11, and the two flip-axis 14 are respectively inserted into one rotating hole. In this way, the first base plate 11 is located between the two flip-axis seats 13, forming a dual-axis synchronous support structure symmetrically distributed on both sides of the first base plate 11. This layout significantly enhances the torsional stiffness and load stability of the flip assembly 10 when rotating around the first direction A, effectively preventing the workpiece (such as the mobile phone case 200) from swaying or vibrating during the tilting positioning process. It is especially suitable for high-precision operations such as precision machining and inspection that have strict requirements for posture stability.

[0031] Please see Figure 2 and Figure 4In this embodiment, the flipping assembly 10 further includes a diagonal brace assembly 15, which includes a guide rail 151 and a connecting rod 152. The guide rail 151 is disposed on the first base plate 11 along the direction perpendicular to the flipping axis 14. One end of the connecting rod 152 is slidably disposed on the guide rail 151, and the other end is rotatably connected to the second base plate 12. Thus, when the second base plate 12 rotates around the flipping axis 14, the connecting rod 152 slides synchronously along the guide rail 151 and adaptively adjusts the support angle. The diagonal brace assembly 15 provides dynamic rigid support for the flipping process, effectively suppressing the lateral torque generated by load offset during the flipping process, thereby significantly improving the stability and balance of the flipping, ensuring that the workpiece (such as the mobile phone case 200) can remain stable and without shaking when positioned at any tilt angle, meeting the requirements of high-precision operation for posture stability.

[0032] Furthermore, there are two diagonal bracing assemblies 15, with two parallel guide rails 151 spaced apart and two connecting rods 152 respectively located on both sides of the second base plate 12. Thus, the symmetrically distributed diagonal bracing assemblies 15 on both sides, together with the double flipping shafts 14, form a stable triangular support frame, achieving uniform load distribution and multi-directional torque balance during flipping. This provides resistance to deformation and vibration even under conditions of large workpiece tilt or uneven load distribution, ensuring the posture stability required for processing / inspection.

[0033] In this embodiment, the connecting rod 152 includes a first connecting rod 153, a second connecting rod 154, a first slider 155, a second slider 156, and an elastic element 157. Both the first slider 155 and the second slider 156 are movably mounted on the guide rail 151, and the elastic element 157 is located between the first slider 155 and the second slider 156. The first slider 155 is located between the second slider 156 and the flipping shaft seat 13. One end of the first connecting rod 153 is rotatably connected to the second base plate 12 via a pin, and the other end is rotatably connected to the first slider 155 via a pin. One end of the second connecting rod 154 is rotatably connected to the second slider 156 via a pin, and the other end is rotatably connected to the first connecting rod 153 via a pin. The elastic element 157 is a spring.

[0034] During the specific flipping process, the second base plate 12 rotates around the flipping axis 14 under force, driving the first connecting rod 153 to push the first slider 155 to slide along the guide rail 151. Simultaneously, the second connecting rod 154 is pulled by the first connecting rod 153 to drive the second slider 156 to move accordingly. At this time, the elastic element 157 located between the first slider 155 and the second slider 156 absorbs the slight displacement caused by the assembly gap between the guide rail 151 and the slider and the deviation of the movement trajectory through adaptive extension and contraction, converting the sliding friction into elastic potential energy for buffer release, thereby suppressing mechanical interference during the flipping process, reducing the jamming phenomenon of the flipping mechanism, and ensuring smooth and stepless switching of the tilt angle.

[0035] Please see Figure 5 and Figure 6 In this embodiment, the flipping assembly 10 further includes a flipping limiting member 16, which is located at a preset position on the first base plate 11. The flipping limiting member 16 includes a movable stop 161, which is movably inserted between the first slider 155 and the second slider 156. When the first slider 155 slides to the predetermined position, the movable stop 161 can be pushed to move towards the first slider 155, so that the movable stop 161 is completely engaged in the movement trajectory of the first slider 155. At this time, the first slider 155 cannot continue to move due to the mechanical obstruction of the movable stop 161, and the flipping angle of the second base plate 12 is rigidly locked by the first connecting rod 153, thereby restricting the second base plate 12 from continuing to flip and achieving rigid positioning of the tilt angle.

[0036] Please see Figure 3 and Figure 4 In this embodiment, the rotating assembly 20 includes a bearing 23 and a rotating shaft 24. The second base plate 12 is provided with a through hole 121. The bearing 23 is located on the side of the second base plate 12 away from the first base 21. One end of the rotating shaft 24 is located on the bearing 23, and the other end passes through the through hole 121 and is connected to the first base 21.

[0037] Furthermore, the rotating assembly 20 also includes a bearing mounting base 25 and a shaft mounting base 26. The bearing mounting base 25 is fixedly connected to the side of the second base plate 12 away from the first base 21. The bearing 23 is disposed inside the bearing mounting base 25. The shaft mounting base 26 is fixedly connected to the bearing mounting base 25. One end of the rotating shaft 24 is rotatably inserted into the shaft mounting base 26.

[0038] Please see Figure 5 and Figure 6 In this embodiment, the rotating assembly 20 further includes a limiting pin 27. The second base plate 12 is provided with a plurality of first insertion holes 122, and the first base 21 is provided with a plurality of second insertion holes 211. The limiting pin 27 is used to insert into the first insertion holes 122 and the second insertion holes 211. Thus, when the rotating assembly 20 drives the workpiece (such as a mobile phone case 200) to rotate around the second direction B to the target angle, the operator simultaneously inserts the limiting pin 27 into the first insertion holes 122 and the second insertion holes 211 on the first base 21 and the second base 22, respectively. The rigid engagement between the pin and the hole wall forcibly locks the relative rotational freedom of the first base 21 and the second base 22, thereby achieving precise positioning of the workpiece with zero clearance.

[0039] In this embodiment, the rotating assembly 20 further includes a plurality of limiting blocks 28, which are disposed on the side of the second base 22 away from the first base 21. The plurality of limiting blocks 28 and the second base 22 together define a receiving area 281, which is used to set the workpiece.

[0040] Please see Figure 2In this embodiment, the fixture 100 further includes a first buffer 30 and a second buffer 31. The first buffer 30 is disposed on the first base plate 11 and located on the side of the second slider 156 away from the first slider 155. It is made of high-damping polyurethane material. When the second slider 156 is impacted by inertia or load and passes the limit of the movable stop 161, the first buffer 30 absorbs the residual kinetic energy of the slider through elastic deformation, physically preventing the second slider 156 from continuing to slide and avoiding rigid collision damage to the guide rail 151 structure. The second buffer 31 is disposed between the adjacent side walls of the first base plate 11 and the second base plate 12. It uses a conical silicone shock-absorbing pad to provide progressive buffering when the flipping assembly 10 is reset to the horizontal zero position, and simultaneously offsets the impact vibration when the second base plate 12 is closed, preventing the workpiece from undergoing micro-displacement due to instantaneous vibration. The two work together to form a bidirectional overload protection mechanism to ensure that there is no impact or rebound throughout the flipping and positioning process.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
