[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0044] The present invention provides a floating support mechanism. During the press-fitting process, the plane floating support has strong adaptability, thereby ensuring the assembly quality and yield rate of the product.

[0045] Please refer to Figures 1 to Fig.12 The floating support mechanism provided by the present invention includes a plane floating support assembly 10 and a clamping and positioning assembly 20; the plane floating support assembly 10 includes a vertical floating plate 11, a horizontal floating plate 12 and a horizontal floating cylinder 13, the horizontal floating cylinder 13 is fixedly arranged at the bottom of the horizontal floating plate 12, an elastic member 14 is arranged between the vertical floating plate 11 and the horizontal floating plate 12, and the elastic member 14 is used to drive the vertical floating plate 11 to float in the vertical direction; the clamping and positioning assembly 20 includes a clamping claw cylinder 21, a positioning seat 22 and a plurality of clamping claws 23, the clamping claw cylinder 21 and the positioning seat 22 are fixedly arranged at the top of the vertical floating plate 11, the clamping claw 23 is installed on the clamping claw cylinder 21, the positioning seat 22 is provided with a positioning hole 2211, the positioning hole 2211 is used to position the input shaft 40, and the clamping claw 23 is used to clamp the input shaft 40. Among them, the elastic member 14 is a floating spring, and the floating spring is arranged vertically.

[0046] When assembling the torque and angle sensor 50 on the input shaft 40, firstly, one end of the input shaft 40 is placed into the positioning hole 2211 of the positioning seat 22 to center the input shaft 40, and the clamping jaws 23 are driven by the clamping jaw cylinder 21 to move and clamp the input shaft 40 to fix the input shaft 40, and then the torque and angle sensor 50 is pressed onto the input shaft 40. During the pressing process, the horizontal float 13 has a horizontal floating function. Under the action of the pressing force, the elastic member 14 between the vertical floating plate 11 and the horizontal floating plate 12 is compressed, and the vertical floating plate 11 moves in the vertical direction. Through such a setting, the torque and angle sensor 50 and the input shaft 40 are adaptively aligned. During the process of pressing the torque and angle sensor 50 onto the input shaft 40, the structure operates stably and the plane floating support has strong adaptability, which can ensure the product assembly quality and yield rate, and ensure the overall performance of the automobile steering system.

[0047] Please refer to Figures 1 to Fig.12 The positioning seat 22 includes a main body 221 and three connecting arms 222. The positioning hole 2211 is provided in the main body 221. The positioning hole 2211 extends in the vertical direction. The connecting arm 222 is fixed to the main body 221. The three connecting arms 222 are evenly distributed along the circumference of the main body 221. A movable space 223 is formed between two adjacent connecting arms 222 for the clamp 23 to pass through to clamp the input shaft 40.

[0048] When the torque and angle sensor 50 is assembled on the input shaft 40, one end of the input shaft 40 is placed in the positioning hole 2211 of the main body 221, and there is a certain gap between the input shaft 40 and the positioning hole 2211 of the main body 221. The three connecting arms 222 are evenly distributed along the circumference of the main body 221, so that the three connecting arms 222 correspond to the positioning shaft 25 one by one, and the connecting arms 222 and the positioning shaft 25 are connected by the fixing member 26. Two adjacent connecting arms 222 and the main body 221 form an activity space 223, and the clamping claw cylinder 21 drives the clamping claw 23 to move through the above-mentioned activity space 223 to complete the clamping of the input shaft 40. With such a configuration, the overall design of the clamping and positioning assembly 20 is reasonable and the structure is compact.

[0049] Please refer to Figures 1 to Fig.12 The number of the clamping jaws 23 is three, and the three clamping jaws 23 are arranged in a circular array, and the clamping jaws 23 are installed with a clamping block 231. The clamping jaw cylinder 21 is a three-jaw cylinder, and the three clamping jaws 23 are installed on the clamping jaw cylinder 21, and the three clamping jaws 23 are arranged in a circular array, and the clamping block 231 is installed on the clamping jaw 23, so that when the clamping jaw cylinder 21 is working, it drives the three clamping jaws 23 to move closer to the center, and the clamping block 231 is pressed against the side of the input shaft 40 to clamp the input shaft 40, so that the input shaft 40 is reliably fixed, and the input shaft 40 can be kept in a vertical state, so that the input shaft 40 is accurately positioned, which is conducive to improving the centering of the input shaft 40 and the torque and angle sensor 50.

[0050] In addition, the side of the clamping block 231 that contacts the input shaft 40 is an arc-shaped surface. Since the input shaft 40 is a cylindrical structure, such a configuration can make the clamping block 231 fully contact the outer side of the input shaft 40, thereby fitting more closely and ensuring the clamping effect.

[0051] Please refer to Figures 1 to Fig.12 The clamping and positioning assembly 20 also includes an auxiliary positioning plate 24 and a positioning shaft 25; the auxiliary positioning plate 24 is arranged in the horizontal direction; the positioning shaft 25 is arranged in the vertical direction, the positioning shaft 25 passes through the auxiliary positioning plate 24 and is fixed to the top of the vertical floating plate 11; wherein, the positioning seat 22 is located at the top of the positioning shaft 25, and the positioning shaft 25 is connected to the positioning seat 22 by a fixing member 26.

[0052] The top of the positioning shaft 25 is inserted into the bottom of the positioning seat 22, and then the connection between the positioning shaft 25 and the positioning seat 22 is achieved through the fixing member 26. Optionally, the fixing member 26 is a fastening bolt or a fastening screw, and the fixing member 26 passes through the positioning seat 22 and is threadedly connected to the positioning shaft 25. Such a setting not only ensures a tight connection and reliable fixation, but also facilitates assembly and disassembly between the positioning shaft 25 and the positioning seat 22.

[0053] Specifically, in the present embodiment, three positioning shafts 25 are provided, and the three positioning shafts 25 are distributed in a circular array, so that the clamping positioning assembly 20 can be reliably fixed on the top of the vertical floating plate 11. When the torque and angle sensor 50 is pressed to be assembled on the input shaft 40, the pressing force transmitted from the clamping positioning assembly 20 as a whole to the vertical floating plate 11 is evenly distributed, thereby improving stability.

[0054] Please refer to Figures 1 to Fig.12 The planar floating support assembly 10 also includes a floating guide column 15, a floating guide sleeve 16 and a floating force column 17; the floating guide column 15 is arranged in the vertical direction, and the bottom end of the floating guide column 15 passes through the vertical floating plate 11 and is fixed to the horizontal floating plate 12; the floating guide sleeve 16 is fixed to the vertical floating plate 11, and the floating guide sleeve 16 is slidably connected to the floating guide column 15; the floating force column 17 is arranged in the vertical direction, and the floating force column 17 passes through the horizontal floating plate 12 and is fixed to the bottom of the vertical floating plate 11.

[0055] When the vertical floating plate 11 moves due to the pressing force, the floating guide sleeve 16 slides along the floating guide column 15. By setting the floating guide sleeve 16 and the floating guide column 15, the movement of the vertical floating plate 11 can be guided to ensure that the vertical floating plate 11 moves in the vertical direction and avoid the vertical floating plate 11 from being offset in the horizontal direction.

[0056] In addition, the horizontal floating plate 12 is correspondingly provided with openings, and the floating force-bearing column 17 passes through the openings and through the horizontal floating plate 12 , thereby ensuring that the floating force-bearing column 17 does not contact the horizontal floating plate 12 .

[0057] Please refer to Figures 1 to Fig.12 The floating support mechanism provided by the present invention also includes a press-fitted force support height switching component 30, which includes a bottom plate 31, a fixed plate 32 and a force lifting plate 33; the bottom plate 31 is horizontally arranged, the fixed plate 32 is parallel to the bottom plate 31, the fixed plate 32 is provided with a through hole 321, and the through hole 321 is used to avoid the clamping positioning component 20; the force lifting plate 33 is slidably arranged between the fixed plate 32 and the bottom plate 31; wherein, the horizontal floating cylinder 13 is fixedly arranged on the top of the force lifting plate 33, and there is a certain gap between the bottom surface of the floating force column 17 and the top surface of the force lifting plate 33.

[0058] The horizontal floating cylinder 13 is fixed to the top of the force lifting plate 33. Through such a setting, the plane floating support assembly 10 and the clamping positioning assembly 20 are fixed to the press-fit force support height switching assembly 30. When the torque and angle sensor 50 is assembled on the input shaft 40, the press-fit force support height switching assembly 30 can withstand a large press-fit force and play a supporting and pressure-bearing role. Moreover, the force lifting plate 33 in the press-fit force support height switching assembly 30 is movably arranged. When the press-fitting work is completed, the position height of the finished part can be adjusted by moving the force lifting plate 33 in the vertical direction, which is convenient for the subsequent automatic unloading operation.

[0059] Please refer to Figures 1 to Fig.12 A connecting column 34 is provided between the bottom plate 31 and the fixed plate 32. The connecting column 34 is arranged in the vertical direction. The two ends of the connecting column 34 are respectively connected to the bottom plate 31 and the fixed plate 32. The force-bearing lifting plate 33 is fixedly provided with a lifting guide sleeve 331. The lifting guide sleeve 331 is slidably connected to the connecting column 34. There are four connecting columns 34, which are distributed at the four corners of the bottom plate 31.

[0060] By providing the connecting column 34 and the lifting guide sleeve 331 , the movement of the force-bearing lifting plate 33 can be guided to ensure that the force-bearing lifting plate 33 moves in the vertical direction and avoid the force-bearing lifting plate 33 from being offset in the horizontal direction.

[0061] Please refer to Figures 1 to Fig.12 Limiting assemblies 35 are fixedly provided on both sides of the bottom plate 31. The limiting assemblies 35 include a driving cylinder 351, a sliding block 353 and a fixed seat 352. The fixed seat 352 is fixedly provided on the top of the bottom plate 31. The driving cylinder 351 is fixedly provided on the fixed seat 352. The sliding block 353 is fixedly provided on the telescopic end of the driving cylinder 351. The sliding block 353 is slidably connected to the fixed seat 352.

[0062] By setting the limit assembly 35, when the torque and angle sensor 50 is assembled on the input shaft 40, the force lifting plate 33 can be limited and fixed, so that the force lifting plate 33 has a pressure-bearing function during press-fitting, and can support the planar floating support assembly 10 and the clamping positioning assembly 20.

[0063] The driving cylinder 351 is used to drive the sliding block 353 to move in the horizontal direction. When in use, the driving cylinder 351 is started to drive the sliding block 353 to slide along the fixed seat 352. The sliding block 353 partially extends from the inside of the fixed seat 352. The top of the part of the sliding block 353 extending from the inside of the fixed seat 352 is used to abut against the bottom surface of the force-bearing lifting plate 33. The force-bearing lifting plate 33 is supported by the part of the sliding block 353 extending from the inside of the fixed seat 352, ensuring that the force-bearing lifting plate 33 can withstand the pressing force during the pressing process and will not move due to the pressing force.

[0064] There are two groups of limit assemblies 35, which are respectively located on both sides of the bottom plate 31. Through such a configuration, it is ensured that the sliding block 353 can provide reliable support for the force-bearing lifting plate 33, thereby ensuring the normal progress of the press-fitting operation.

[0065] Please refer to Figures 1 to Fig.12 A lifting cylinder 36 is fixedly provided on the top of the bottom plate 31, and the telescopic end of the lifting cylinder 36 is connected to the force lifting plate 33. The lifting cylinder 36 is used to drive the force lifting plate 33 to move in the vertical direction. When the press-fitting work is completed, the lifting cylinder 36 is started to drive the force lifting plate 33 to move in the vertical direction, thereby adjusting the position height of the finished part, which is convenient for the subsequent use of a mechanical arm to complete the unloading and transfer of the finished part.

[0066] Please refer to Figures 1 to Fig.12 The force lifting plate 33 is provided with a notch 332, and the notch 332 is used to avoid the fixing seat 352 when the force lifting plate 33 is lifted. By providing the notch 332, when the torque and angle sensor 50 is assembled on the input shaft 40, the force lifting plate 33 can avoid the fixing seat 352, so that the sliding block 353 can contact the force lifting plate 33 and provide support for the force lifting plate 33, thereby playing a pressure-bearing role.

[0067] In addition, the floating support mechanism provided by the present invention further includes a sensor positioning block 27, which is fixed on one of the connecting arms 222 of the positioning seat 22, and the sensor positioning block 27 is provided with a limiting groove 271. The torque and angle sensor 50 clamps the input shaft 40 for interference fit after press-fitting, but the outer ring of the torque and angle sensor 50 can rotate freely. The sensor positioning block 27 is used for orienting the outer ring of the torque and angle sensor 50. When in use, the outer ring of the torque and angle sensor 50 is clamped in the limiting groove 271 of the sensor positioning block 27 to prevent the outer ring of the torque and angle sensor 50 from rotating, thereby ensuring the stability of the grip when the material is automatically unloaded by a mechanical arm after the press-fitting is completed.

[0068] In the floating support mechanism provided by the present invention, when the torque and angle sensor 50 is assembled on the input shaft 40, one end of the input shaft 40 is placed in the positioning hole 2211 of the positioning seat 22 to perform center positioning on the input shaft 40, and the clamping claw 23 is driven by the clamping claw cylinder 21 to move and clamp the input shaft 40 to fix the input shaft 40. During the press-fitting process, the horizontal floating cylinder 13 has a horizontal floating function. Under the action of the press-fitting force, the elastic member 14 between the vertical floating plate 11 and the horizontal floating plate 12 is compressed, and the vertical floating plate 11 moves in the vertical direction. Through such a setting, the torque and angle sensor 50 and the input shaft 40 are adaptively aligned. During the process of the torque and angle sensor 50 being press-fitted on the input shaft 40, the structure operates stably, and the plane floating support has strong adaptability, which can ensure the product assembly quality and yield rate, and ensure the overall performance of the automobile steering system.

[0069] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0070] The principles and implementation methods of the present invention are described in this article using specific examples. The description of the above embodiments is only used to help understand the method and core ideas of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made to the present invention without departing from the principles of the present invention, and these improvements and modifications also fall within the scope of protection of the present invention.
