Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hub bearing packaging, in particular to a universal packaging for vehicle hub bearings. BACKGROUND

[0002] The vehicle hub bearing is a core precision component in the automobile driving system, and its performance directly affects the driving safety, smoothness and service life of the vehicle. Due to the differences in vehicle models, wheelbase, load requirements, etc., the specifications of hub bearings show significant diversification characteristics. Not only are the diameters and thicknesses different, but the structural forms are also different, including split bearings with flanges, unit bearings integrated with ABS sensor lines, etc. This diversity leads to the need for packaging that is specifically adapted to different sizes and shapes of bearings, posing challenges for packaging design and application.

[0003] Traditional packaging solutions often use special structures for specific models of bearings, such as customized foam slots, special-shaped cartons, or mold-formed plastic boxes, etc. Such packaging achieves good protection by precisely matching the bearing shape, but has limitations: when the bearing model changes, the original packaging cannot be reused due to size and structural incompatibility, and new packaging must be designed and produced, which not only increases the cost of packaging materials and mold development, but also leads to a large accumulation of idle packaging in inventory, making it difficult to adapt to the flexible production requirements of the automobile parts industry with multiple varieties and small batches, and restricting the improvement of production efficiency.

[0004] However, existing universal packaging solutions often use a uniform oversized structure to cover a wider range of bearing specifications, which raises new problems: for small-sized bearings, a large amount of redundant space is generated inside the packaging, resulting in a significant decrease in loading rate during transportation and a decrease in space utilization during storage, directly increasing logistics and inventory costs; at the same time, due to the lack of fixing structures for different bearings, the bearings are prone to shaking and colliding inside the packaging during transportation, causing damage such as raceway scratches and seal ring deformation, affecting product quality; when stacked in multiple layers, the entire box is prone to tipping due to the lack of stable limiting structures, further increasing the risk of bearing damage, and manual picking and placing requires adjusting the fixing one by one, which is relatively cumbersome. Therefore, it is necessary to design a universal packaging for vehicle hub bearings.

[0020] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0021] The technical solutions provided by the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Reference Figures 1-4 As shown, this embodiment of the invention provides a universal packaging for vehicle wheel bearings, including a packaging component 1. The packaging component 1 consists of a stacking box 11 at the bottom, multiple stacking boxes 12 in the middle, and a stacking box 13 at the top. Each of the stacking boxes 11, 12, and 13 has multiple regularly arranged receiving slots 14. These receiving slots 14 are used to accommodate and store vehicle wheel bearings. Through the multi-layer stacking structure, universal packaging and storage of wheel bearings of different quantities and specifications can be achieved. And the staggered frame plate one 111 is integrally formed on the side of the stacking box one 11, and a regular side support structure is constructed by the horizontal and vertical plate members; the stacking box two 12 is provided with a staggered frame plate two 121 corresponding to the side, which is adapted to the structure of the frame plate one 111, and guarantees the fitting precision when stacking multiple layers; the stacking box three 13 is provided with a frame plate three 131 on the side, which continues the staggered design logic of the previous two, so that the entire package has a unified structure reference when stacking multiple layers. In order to realize the stable connection of adjacent stacking boxes, the stacking assembly 2 is specially set, and the connection between the stacking box one 11 and the stacking box two 12 is taken as an example to expand the description; And the stacking assembly 2 includes a butt joint part fixedly installed at the four corners of the frame plate one 111, the butt joint part includes two groups of tenon parts 21 symmetrically arranged at the four corners of the frame plate one 111, the tenon part 21 has a protruding part 22, and a mortise part 23 corresponding in number to the tenon part 21 is fixedly installed on the frame plate two 121, the mortise part 23 has a recessed part 24, when the stacking operation is performed, the frame plate one 111 can be precisely inserted through the protruding part 22 and the recessed part 24, and the positioning of the adjacent stacking box one 11 and the stacking box two 12 is quickly completed, so that the multiple layers have a good alignment basis in the initial stage, and the layer misalignment is avoided; Reference Figures 2-4 As shown in the figure, in order to further strengthen the connection stability of adjacent stacking boxes, a locking part 25 is arranged between the tenon part 21 and the mortise part 23. The locking part 25 is a key supplementary structure of the stacking assembly 2, which can further fasten the adjacent stacking boxes on the basis of tenon and mortise positioning, so as to avoid the layer loosening caused by vibration and bumping during transportation; The locking part 25 includes a fixed base 251 fixedly installed on the mortise part 23, and an outwardly extending protruding seat 252 is integrally formed on the fixed base 251, a handle 253 is hingedly installed on the protruding seat 252, the handle 253 can be flexibly rotated around the hinge shaft of the protruding seat 252, and the handle 253 is convenient for the operator to operate, and a rotating shaft 254 is movably installed on the handle 253, and the rotating shaft 254 can drive the subsequent components to move through the rotating characteristics; And a U-shaped hanging rod 255 is assembled on the rotating shaft 254 through a fastener, the hanging rod 255 can adjust the posture with the action of the rotating shaft 254 and the handle 253, and correspondingly, a hooking part 256 adapted to the hanging rod 255 is fixedly installed on the tenon part 21. When the tenon and mortise insertion positioning is completed, the operator rotates the handle 253 to make the hanging rod 255 accurately hook on the hooking part 256, and then reversely rotates the handle 253 to tighten, so that the adjacent stacking boxes can be firmly fixed through the mechanical force of the locking part 25, forming a double connection of tenon and mortise positioning and locking part 25 fastening, improving the structural stability of the multiple layer stacking package, and meeting the demand of the packaging strength for vehicle hub bearing transportation; It should be noted that, in order to adapt to the multi-layer stacking requirement, realize the universal docking of different levels of stacked boxes, the upper and lower surfaces of the frame plate two 121 on the multiple groups of stacked boxes two 12 between the stacked box one 11 and the stacked box three 13 and at the four corners are respectively integrated with the mortise part 23 and the tenon part 21. This symmetrical structure layout makes the stacked box two 12 have both the mortise interface for receiving the tenon of the upper stacked box and the tenon structure for inserting into the mortise of the lower stacked box; When the multiple groups of stacked boxes two 12 are interlayerly docked and fixed, the tenon part 21 at the bottom of the upper stacked box two 12 can be precisely inserted into the mortise part 23 at the top of the lower stacked box two 12, and the locking part 25 of the stacked assembly 2 is used to quickly complete the positioning and fastening of the adjacent stacked boxes two 12. This design makes the stacked box two 12 become a universal layer that can be flexibly adapted to the connection between the upper and lower layers. No matter how many groups of stacked boxes two 12 are arranged in the middle, the unified mortise and tenon interface and locking structure can be used to realize the stable connection of multi-layer stacking, build a three-dimensional packaging system suitable for storing and transporting vehicle hub bearings, and greatly improve the universality and expansibility of the packaging structure. At the same time, in order to ensure the overall stability of multi-layer stacking, the multiple groups of adjacent stacked boxes two 12 are also fixed by the locking part 25 after the preliminary docking by the mortise part 23 and the tenon part 21. Since the upper and lower surfaces of the frame plate two 121 of the stacked box two 12 are respectively integrated with the mortise part 23 and the tenon part 21 at the four corners, when the tenon part 21 of the upper stacked box two 12 is inserted into the mortise part 23 of the lower stacked box two 12 to achieve preliminary positioning, the locking part 25 can further reinforce the interlayer connection. The fixing logic of the locking part 25 is consistent with the connection of the stacked box one 11 and the stacked box two 12: the fixed base 251, the protruding seat 252 and the handle 253 on the mortise part 23 of the lower stacked box two 12 support the rotation of the handle 253, the handle 253 drives the U-shaped hanging rod 255 through the rotating shaft 254, and the U-shaped hanging rod 255 is precisely hooked on the hooking part 256 of the tenon part 21 of the upper stacked box two 12. After the handle 253 is reversely rotated to tighten, the adjacent stacked boxes two 12 are firmly locked by the mechanical force. This design makes the interlayer connection of the multiple groups of stacked boxes two 12 have both the alignment accuracy of mortise and tenon positioning and the fastening strength of the locking part 25, which ensures the stability and reliability of the entire multi-layer packaging structure during transportation and handling, and adapts to the multi-layer bearing requirement of universal packaging of vehicle hub bearings.

[0023] In use, the stacked box structure is used to realize interlayer docking. The stacked box one 11, the stacked box two 12 and the stacked box three 13 form a unified stacking reference through the staggered design of the frame plates. The symmetrical tenon part 21 and mortise part 23 integrated on the upper and lower surfaces of the stacked box two 12 can adapt to multi-layer continuous stacking. When stacking, the tenon part 21 of the upper stacked box is inserted into the recess part 24 of the corresponding mortise part 23 of the lower stacked box, and the precise insertion of the protrusion and the recess quickly completes the preliminary positioning between the layers, ensuring that the stacked boxes of each layer are aligned and laying a foundation for subsequent reinforcement.

[0024] Then, the interlayer fastening is completed relying on the locking part 25. The locking part 25 is supported by the fixed base 251 and the protruding base 252. The operator rotates the handle 253. The U-shaped hanging rod 255 is linked through the rotating shaft 254 to make it hooked on the hooking part 256 of the tenon head part 21. The handle 253 is reversely rotated to tighten. The adjacent stacked boxes are locked by using mechanical force. Whether it is the stacked box one 11 and the stacked box two 12 or the multiple groups of stacked box two 12, they are connected by the mortise and tenon pre-positioning and the locking part 25 fastening double connection. It guarantees the stability and reliability of the multi-layer structure in transportation and carrying. It adapts to the storage and transportation demand of different number and specification hub bearings. It realizes the stable load bearing and protection of universal packaging.

[0025] In order to solve the problem that the vehicle hub bearing is easy to shake when placed in the containing groove 14, as shown in the prior art, Figures 5-8 A clamping assembly 3 is arranged in the containing groove 14 of the stacked box. The clamping assembly 3 is flexibly clamped to the bearing through the fixed limiting and movable adaptive structure to guarantee the stability in transportation. The clamping assembly 3 includes a fixed part arranged on one side of the inner wall of the containing groove 14. The fixed part is used for limiting one side edge of the vehicle hub bearing when it is placed. The fixed part includes a fixed sleeve rod 311 fixedly installed on one side of the inner wall of the containing groove 14. The fixed sleeve rod 311 is a hollow structure. A connecting angle plate 312 is integrally arranged on both sides of the fixed sleeve rod 311. The connecting angle plate 312 is fixedly connected with one side of the inner wall of the containing groove 14 through fasteners to ensure the stable installation of the whole fixed part. An active plate 313 is slidably arranged at one end of the fixed sleeve rod 311. One end of the active plate 313 extends into the fixed sleeve rod 311 and is connected with one end of the inner wall of the fixed sleeve rod 311 through a spring to initially limit the position of one end of the active plate 313. A waist block 315 is fixedly installed on the upper and lower surfaces of the active plate 313. A waist groove 314 is formed in the fixed sleeve rod 311 for the sliding of the waist block 315. The active plate 313 is adapted to slide along the linear direction of the waist groove 314 through the waist block 315 to provide guidance and limiting for the active plate 313. Meanwhile, a screw (not shown in the figure) is connected with the fixed sleeve rod 311. The screw is threadedly connected with the active plate 313 through the fixed sleeve rod 311. A second clamping half ring 316 is fixedly installed at one end of the active plate 313 away from the fixed sleeve rod 311. The second clamping half ring 316 is adapted to limit one side edge of the vehicle hub bearing when it is placed. A silicone material anti-skid pad (not shown in the figure) is arranged at the contact area between the second clamping half ring 316 and the vehicle hub bearing. The half ring structure is adapted to the bearing shape to realize unilateral limiting. The silicone material cushioning and shock absorption avoid rigid contact damage to the bearing. It lays a foundation for subsequent unilateral clamping or overall limiting to improve the stability of the bearing placed in the containing groove 14. To realize the full range of stable clamping on both sides of the vehicle hub bearing, form a more reliable anti-shake state, as Figures 5-8 shown, in addition to unilateral fixed part, in the other side of the accommodation groove 14 inner wall through the setting of the movable part, the movable part with two groups of limit rod 33 as the core, limit rod 33 on the integral limit strip 331, at the same time in the accommodation groove 14 corresponding to set through hole (not shown in the figure) with limit rod 33, limit strip 331 adaptive, using limit strip 331 and through hole cooperation, limit limit rod 33 can only be linearly moved along the through hole, avoid deviation, for the displacement of the movable part to provide the basis of the guide; two groups of limit rod 33 one end common fixed clamping seat 32, clamping seat 32 away from the limit rod 33 one end installation first clamping half ring 38, first clamping half ring 38 and vehicle hub bearing contact area, also pasted with silica gel material anti-skid pad, soft texture and large friction, both can adapt to the bearing shape to realize flexible clamping, but also can avoid rigid contact damage bearing surface. In addition, in the side of clamping seat 32 through bearing with two groups of limit rod 33 parallel screw rod 34, for the driving of the movable part to provide transmission path. At the same time, in the vertical direction of the stack box distribution of accommodation groove 14, through the configuration of the driving part (can combine Figure 1 understand the overall layout), used to drive the movable part close to or away from the vehicle hub bearing, realize the adjustment of clamping tightness.

[0026] drive part contains through the bearing set in the vertical direction of the accommodation groove 14 in the drive shaft 36, drive shaft 36 on the processing of a plurality of worm 37, worm 37 number and the number of accommodation groove 14 one to one correspondence, ensure that each accommodation groove 14 in the movable part can be independently and synchronously driven, screw rod 34 on the thread connection worm gear 35, worm gear 35 and worm 37 meshing, constitute worm 37 worm gear 35 transmission pair, realize the conversion of motion direction and power transmission; to protect the worm gear 35 stable operation, in the side of the worm gear 35 through the bearing installation support shaft seat 351, support shaft seat 351 one end and the inner wall bottom of the accommodation groove 14 firmly fixed, and support shaft seat 351 on the screw rod 34, with screw rod 34 does not contact, both for screw rod 34 and worm gear 35 provide stable support, but also do not interfere with the rotation of the screw rod 34. Drive shaft 36 extending out of the stack box one end fixed installation turntable 39; operator turntable 39, can drive the drive shaft 36 rotation, through the worm 37 worm gear 35 transmission, drive screw rod 34 rotation, and make clamping seat 32 along the limit rod 33 linearly moving, adjust the first clamping half ring 38 and the distance between the vehicle hub bearing, complete the clamping or loose action. When the rotation to the appropriate position, the fixed block 310 fixedly sleeved on the drive shaft 36, can be through the fastener and the stack box surface thread connection, lock the drive shaft 36, ensure that the clamping force of the movable part to the bearing is stable and reliable, will not be due to the factors such as vibration loose; In addition, to avoid the vehicle wheel hub bearing from being damaged by knocking against the inner wall bottom surface of the accommodating groove 14 during transportation, a flexible support pad 31 is installed on the inner wall bottom surface of the accommodating groove 14 by means of fasteners. The support pad 31 is provided with a hole 317 in the center, and the protrusion at the bottom of the vehicle wheel hub bearing can be placed in the hole 317. The flexible material is used for buffering and shock absorption, and the hole 317 is used for limiting the bottom of the bearing. In cooperation with the double-sided clamping structure, a multi-dimensional protection system is formed from the bottom and both sides to ensure the stability of the vehicle wheel hub bearing in the accommodating groove 14 and meet the anti-shaking requirements during transportation and storage.

[0027] It should be noted that the two groups of limiting rods 33 in the accommodating groove 14 penetrate through the adjacent accommodating grooves 14 and extend into the fixed sleeve rod 311. This kind of cross-slot penetrating design makes the movable part and the fixed part form a spatial linkage through the limiting rod 33, reduces the component sparsity, and improves the integration of the internal structure of the package. At the same end of the movable plate 313 facing the limiting rod 33, a through hole (not shown in the figure) is provided which is adapted to the two groups of limiting rods 33. When the limiting rod 33 penetrates through the accommodating groove 14 and is inserted into the fixed sleeve rod 311, the movable plate 313 can be sleeved on the limiting rod 33 through the through hole, so that the movable plate 313 and the second clamping half-ring 316 of the fixed part and the limiting rod 33 and the first clamping half-ring 38 of the movable part form a cross-limiting and cooperating clamping structure. On the one hand, the limiting rod 33 provides additional guidance for the sliding of the movable plate 313, which cooperates with the guidance of the waist block 315 and the waist groove 314 to ensure the straight-line movement precision of the movable plate 313 from two dimensions, avoiding the deviation of the second clamping half-ring 316 during clamping. On the other hand, the limiting rod 33 penetrating through the slots connects the clamping assemblies 3 of the adjacent accommodating grooves 14 into a whole, which cooperates with the transmission of the worm 37 and the worm gear 35 of the driving part to realize the synchronous adjustment of the clamping structure in multiple accommodating grooves 14. This not only improves the operation efficiency, but also ensures the consistency of the clamping force of each accommodating groove 14 on the bearing, so that the vehicle wheel hub bearing can obtain stable and balanced clamping protection in the array of multi-layer stacked accommodating grooves 14, further improving the anti-shaking and anti-damage ability of the universal package for the bearing from the structural design level.

[0028] Working principle: The multi-layer stacking of the universal package for the vehicle wheel hub bearing is realized by relying on the staggered design of the frame plate and the stacking assembly 2. The frame plates of the stacking box one 11, the stacking box two 12, and the stacking box three 13 are crossed by horizontal and vertical plate pieces to form a unified stacking reference. The stacking box two 12 is integrated with symmetrical tenon parts 21 and mortise parts 23 on the upper and lower surfaces to meet the requirement of multi-layer continuous stacking. When the layers are connected, the tenon part 21 of the upper stacking box is inserted into the recess part 24 of the corresponding mortise part 23 of the lower layer, and the precise insertion of the protrusion and the recess is used to complete the pre-positioning, ensuring that the stacking boxes of each layer are aligned and laying a foundation for subsequent reinforcement. The locking portion 25 is a secondary fastening structure, and the base 251 and the protrusion seat 252 are used as supports. An operator rotates the handle 253, and the U-shaped hanging rod 255 is connected to the hooking portion 256 of the tenon head portion 21 through the rotating shaft 254. The handle 253 is reversely rotated to be tightened, and the adjacent stacked boxes are locked through the mechanical force. No matter the stacked box one 11 and the stacked box two 12 or the multiple groups of stacked box two 12, the tenon and mortise pre-positioning and the locking portion 25 are used for fastening the double connection, so that the multi-layer structure is stable and reliable during transportation and carrying, and the storage and transportation requirements of different numbers and specifications of hub bearings are met.

[0029] In order to solve the problem of bearing shaking in the accommodation groove 14, the fixed portion is installed on one side of the inner wall of the accommodation groove 14. The fixed sleeve rod 311 is fixed with the accommodation groove 14 through the connecting angle plate 312. The movable plate 313 is guided by the waist block 315 and the waist groove 314, and the displacement adjustment is realized through the bolt driving. The second clamping half ring 316 at the end cooperates with the silica gel non-slip pad to flexibly limit one side of the bearing. The movable portion takes two groups of limiting rods 33 as the core. The limiting rod 33 is provided with a limiting strip 331 and moves linearly along the through hole of the accommodation groove 14. The first clamping half ring 38 on the clamping seat 32 is also provided with a silica gel non-slip pad, and forms a ring type clamping with the second clamping half ring 316. The driving portion is driven through the transmission of the driving shaft 36, the worm 37, the worm gear 35 and the screw rod 34. An operator rotates the rotating disc 39 to drive the clamping seat 32 to move and adjust the clamping distance. The fixed block 310 locks the driving shaft 36 after being rotated to the position, so as to ensure the stability of the clamping force. The flexible supporting pad 31 on the bottom surface of the accommodation groove 14 is adapted to the protrusion at the bottom of the bearing through the center insertion hole 317, so as to realize the bottom limiting and buffering and shock absorption, and multiple dimensions are used to ensure the stability of the bearing.

[0030] In the embodiment two, different from the above-mentioned embodiment, in order to adapt to the packaging requirements of different hub bearings, a fastening assembly 4 is arranged on the stacked box. The fastening assembly 4 is used for fixing a single hub bearing, and the fastening assembly 4 comprises a clamping portion fixedly installed on the stacked box. The clamping portion takes the protruding plate 45 as the basis, and the bottom table 44 is fixed on the stacked box through the protruding plate 45. The positioning table 46 is integrally fixed at the center of the protruding plate 45. The vertical rod 47 vertically arranged is penetrated through the bearing on the positioning table 46. The vertical rod 47 is provided with an anti-dropping portion at one end. The locking rod 416 is fixedly sleeved on the vertical rod 47. The spring 48 is sleeved on the vertical rod 47. One end of the spring 48 is connected with the anti-dropping portion, and the other end is connected with the locking rod 416. The spring 48 is elastically connected with the vertical rod 47, and the clamping or loosening of the hub bearing is completed through the elastic linkage of the spring 48 and the subsequent hinged rod action.

[0031] Meanwhile, hinge rods 412 are hinged to both sides of the positioning platform 46. A mounting base 49 is fixedly installed at one end of the vertical rod 47 that passes through and extends into the base platform 44. A through hole (not shown in the figure) is opened in the center of the base platform 44. Hinges 411 are movably connected to both ends of the mounting base 49. One end of hinge rod 411 is movably connected to hinge rod 412. One end of hinge rod 412 is provided with a clamping part for clamping the wheel hub bearing (which can be understood by combining the structure of the end of the hinge rod in the figure that adapts to the shape of the wheel hub bearing to achieve precise clamping). The mounting base 49 is moved down by the vertical rod 47 to link hinge rod 411 and hinge rod 412, so that the clamping part opens and closes, and the clamping and fixing or releasing operation of the wheel hub bearing is completed. It should be noted that the clamping anisotropic part at one end of the second hinge rod 412 is an adaptive structure specifically designed based on the structural characteristics of the wheel hub bearing. Its inner contour closely matches the outer surface shape of the wheel hub bearing, forming an arc-shaped clamping surface that complements the contour of the step 43, enabling a tight, wrap-around clamping. In this embodiment, only the structure of the clamping anisotropic part matching the specific specification wheel hub bearing in the attached drawings is shown. As can be seen from the attached drawings, the wheel hub bearing body 41 has clear structural features: its center has a through hole 42 for mounting with components such as wheel axles. The edge of the through hole 42 is designed with rounded chamfers to form a smooth transition, avoiding scratches during assembly. At the same time, a step 43 extends outward along the outer periphery of the wheel hub bearing body 41, forming a radially protruding annular structure. Its axial height and radial width precisely form a clearance fit with the inner groove of the clamping anisotropic part. An elastic buffer layer (not shown in the figure) is also provided inside the groove, further improving the tightness and safety of the clamping.

[0032] Meanwhile, one end of the vertical rod 47 is vertically inserted through the center of the mounting base 49, forming a T-shaped connection structure. A fixing plug 410 adapted to the inner diameter of the through hole 42 is fixedly installed at the top of the vertical rod 47. The fixing plug 410 adopts a conical truncated structure design, with its top diameter slightly smaller than the minimum inner diameter of the through hole 42 and its bottom diameter matching the maximum inner diameter of the through hole 42, which facilitates the insertion of the wheel hub bearing. Multiple sealing rings (not shown in the figure) are arranged around the position where the fixing plug 410 contacts the inner wall of the through hole 42. The sealing rings are made of wear-resistant nitrile rubber, which not only ensures a tight fit between the two but also buffers slight vibrations during transportation.

[0033] When the fastening assembly 4 is in operation, the operator holds the outer circumferential surface of the hub bearing body 41 and presses downward. At this time, because the initial elastic pre-tightening force of the spring 48 is greater than the friction force of the sealing ring clamped in the through hole 42, the hub bearing body 41 is first smoothly sleeved on the fixed plug 410 through the through hole 42. With the continuous application of the downward pressure, the fixed plug 410 moves downward synchronously with the hub bearing and pushes the vertical rod 47 to compress the spring 48. At this time, the downward movement of the vertical rod 47 drives the mounting seat 49 to synchronously descend, forcing the hinged rod one 411 on the two sides to rotate downward with the connecting point of the mounting seat 49 as the axis. The other end of the hinged rod one 411 then links the middle position of the hinged rod two 412, thereby linking the hinged rod two 412 to rotate inward along the hinge with the positioning table 46. Finally, the clamping of the two ends of the clamping heterogeneous part is synchronously tightened, and the clamping and fixing of the hub bearing body 41 is completed.

[0034] At this time, the clamping heterogeneous part can be clamped into the step 43, and the step 43 and the clamping heterogeneous part form axial limiting, which can withstand the impact force in the axial direction. At the same time, the outer side surface of the step 43 and the arc-shaped clamping surface on the inner side of the clamping heterogeneous part form radial limiting, which limits the radial movement of the bearing. This double limiting structure not only avoids the direct action of the clamping force on the raceway of the hub bearing body 41, effectively protecting the dimensional accuracy and surface finish of the bearing, but also limits the axial movement and radial deviation of the hub bearing in the stacking box in all directions, cooperating with the concentric positioning effect of the fixed plug 410 and the sealing ring, to ensure the stable and fixed state of the bearing during transportation and storage.

[0035] In order to further improve the stability of the clamping of the hub bearing by the clamping part, referring to Figures 9-12 The locking rod 416 is provided with a friction part, which includes clamping columns 417 fixed at both ends of the locking rod 416. An arc-shaped groove 441 is formed in the bottom surface of the base table 44, which is suitable for the sliding of the clamping columns 417. The contact position of the clamping columns 417 and the arc-shaped groove 441 is provided with an anti-slip pad (not shown in the figure). The groove bottom of the arc-shaped groove 441 is designed in a gradual manner, smoothly transitioning from shallow to deep. In the initial state, the clamping columns 417 are located in the deep groove of the arc-shaped groove 441. Meanwhile, the driving part for driving the clamping column 417 to rotate is arranged on the base 44, which comprises two groups of symmetrically distributed support rods 413 fixedly installed on the base 44, a horizontally arranged worm 414 installed between the two groups of support rods 413 through bearings, one end of the worm 414 extending to the outside of the support rod 413 and provided with an operation knob 415, and a worm wheel 418 engaged with the worm 414 and supported on the base 44 through a bearing seat, the worm wheel 418 movably sleeved on the vertical rod 47, and a vertical pin block integrally arranged on the inner side of the worm wheel 418, and correspondingly, a long strip-shaped pin slot with a length slightly larger than the maximum downward moving distance of the vertical rod 47 is formed on the vertical rod 47 at the same height position, so that the worm 414 can drive the worm wheel 418 to synchronously rotate by rotating, and the worm wheel 418 drives the vertical rod 47 to rotate through the cooperation of the pin block and the pin slot, and the pin block can slide along the length direction of the pin slot during the upward and downward movement of the vertical rod 47, so that the vertical rod 47 can realize the upward and downward movement in the vertical direction and also can complete the rotating action under the action of the driving part, and then the clamping force is adjusted and locked through the cooperation of the locking rod 416 and the arc-shaped slot 441.

[0036] When the hub bearing is clamped by the clamping part, the operator can manually hold the operation knob 415 and apply a rotating force to drive the worm 414 to rotate around its axis, and since the worm 414 and the worm wheel 418 are in engagement, the rotating force of the worm 414 is transmitted to the worm wheel 418 to drive the worm wheel 418 to synchronously rotate around the axis of the vertical rod 47; at this time, the worm wheel 418 drives the vertical rod 47 to synchronously rotate through the cooperation of the pin block on the inner side and the pin slot on the vertical rod 47, and the rotation of the vertical rod 47 drives the clamping column 417 fixed at both ends of the locking rod 416 to rotate, and in this process, the end of the clamping column 417 slides along the inner wall of the arc-shaped slot 441 from the deep groove area to the shallow groove area. Since the groove bottom of the arc-shaped slot 441 is a gradual change structure from deep to shallow, when the clamping column 417 slides to the shallow groove area, the clamping column 417 is forced to tightly contact with the anti-skid pad of the shallow groove area of the arc-shaped slot 441, and mechanical locking is realized by increasing the friction force, and the clamping effect of the double fixing structure is formed by cooperating with the clamping of the step 43 by the clamping female part, so as to further improve the fixing effect of the hub bearing and effectively prevent the clamping from loosening due to vibration during transportation.

[0037] Working principle: when the hub bearing needs to be fixed, the operator aligns the through hole 42 of the hub bearing body 41 with the fixed plug 410 and presses downward. Under the initial pre-tightening force of the spring 48, the hub bearing is first sleeved into the fixed plug 410 of the conical table structure through the through hole 42, and the sealing ring is in close contact with the inner wall of the through hole 42 to realize preliminary positioning; continuous pressing makes the vertical rod 47 overcome the elastic force of the spring 48 and move downward, driving the mounting seat 49 to synchronously descend, and then pushing the hinge rod two 412 to rotate inward around the hinge point of the positioning table 46 through the hinge rod one 411, so that the clamping female part is gradually tightened and finally clamped at the step 43 of the hub bearing, forming double limiting in the axial and radial directions, and completing preliminary clamping and fixing.

[0038] To further ensure the clamping stability, the operator rotates the operation knob 415 to drive the worm one 414 to rotate, and through the meshing transmission of the worm and worm gear one and the worm gear one 418, the worm gear one 418 drives the vertical rod 47 to rotate through the cooperation of the pin block and the pin groove, and then makes the clamping column 417 at both ends of the locking rod 416 slide along the arc-shaped groove 441 on the bottom surface of the bottom table 44 from the deep groove area to the shallow groove area. Because the groove bottom of the arc-shaped groove 441 is designed to be gradually changed, the clamping column 417 is in close contact with the non-slip pad in the shallow groove area to generate a large friction force, and at the same time forces the vertical rod 47 to slightly move upward to compress the spring 48 to form an additional pre-tightening force, which together with the clamping action of the clamping female part forms a double fixing structure, effectively preventing loosening caused by vibration during transportation, and realizing stable fixing of the hub bearing.
