Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of part assembly, and particularly relates to a wheel hub mute cotton automatic attaching device and method. BACKGROUND

[0002] Attaching mute cotton to the inner wall of a wheel hub is a common technical means for reducing tire noise of a vehicle, and is mainly performed by a host factory, a refitting factory or a refitting shop, so that there is a large market gap for automatic construction equipment; in the prior art, the host factory mostly performs operation through a standardized and fully-automatic assembly line, which is high in cost and high in requirement for a working environment, and in a small refitting factory or a refitting shop, operation is still mostly performed manually, which is time-consuming and laborious and poor in consistency.

[0003] The refitting unit faces various forms of wheel hubs, and it is difficult to design several jigs corresponding to the inner contour of the wheel hub like the host factory, so that the demand scenario is not only more sensitive to cost and price, but also more complex in actual working conditions.

[0004] Through investigation and technical analysis, the main difficulties are as follows:

[0005] A: If a relatively hard rubber roller is used, the deformation amplitude of the rubber is insufficient to adapt to the ups and downs of the wheel hub, and the rolling force is different at different deformation amplitude positions; if a relatively soft sponge roller is used, it is difficult to transmit sufficient rolling force.

[0006] B: It is not very convenient to manually cut the mute cotton belt in a narrow rolling operation space. SUMMARY

[0007] In view of the above situation, in order to overcome the defects of the prior art, the application provides a wheel hub mute cotton automatic attaching device and method, and the application provides an equal-pressure imitation form rolling assembly, through an air shaft sleeve capable of freely deforming and having an equal-pressure characteristic, the equal-pressure imitation form rolling assembly can keep the pressure of each rolling wheel on the wheel hub stable after each rolling wheel is attached to the inner contour of the wheel hub, and in combination with the deformation characteristic of a rubber tire in a small width range, the equal-pressure imitation form rolling assembly can be attached to the inner wall of the wheel hub; in addition, the shearing and pushing assembly can automatically cut the mute cotton belt after one cycle of pasting, and the process of subsequent cycle rolling is not affected.

[0008] The technical scheme adopted by the present application is as follows: the present application provides a wheel hub mute cotton automatic bonding device, which comprises an equal-pressure imitation-form rolling assembly, a shearing assembly, a shearing and stirring assembly, a pneumatic lifting assembly, a wheel hub supporting assembly, a feeding assembly and a rack, the equal-pressure imitation-form rolling assembly is arranged on the pneumatic lifting assembly, the shearing assembly is arranged on the pneumatic lifting assembly, the shearing and stirring assembly is arranged on the shearing assembly, the pneumatic lifting assembly is arranged on the feeding assembly, the feeding assembly is arranged on the rack, and the wheel hub supporting assembly is arranged on the rack.

[0009] The equal-pressure imitation-form rolling assembly comprises an air shaft sleeve, bearings, rolling wheels and rubber tires, the air shaft sleeve is sleeved on the bottom of the pneumatic lifting assembly, the bearings are arranged on the air shaft sleeve, the rolling wheels are rotatably arranged on the bearings, and the rubber tires are sleeved on the outside of the rolling wheels.

[0010] The air shaft sleeve has the characteristic of equal pressure, so that the downward pressure of each bearing is equal, thereby keeping consistent downward pressure in the case that the offset amplitudes of the rolling wheels relative to the shaft are different.

[0011] Further, the side surfaces of each group of rolling wheels are in contact and can slide relative to each other, so that even if the groups of bearings are not coaxial, the central axes of the groups of bearings are still parallel to each other.

[0012] The width of each rubber tire is relatively narrow, so that even if different parts of the same rubber tire have different compression amounts due to the slope of the inner wall of the wheel hub, the difference in elasticity is relatively small, thereby ensuring that the pressure of the entire rolling surface is within a relatively small fluctuation range.

[0013] Further, the shearing assembly comprises a fixed shear, a sliding shear, a guide sliding groove and a guide sliding rod, the fixed shear is fixedly connected to the pneumatic lifting assembly, the sliding shear is fixedly connected to the guide sliding rod, the guide sliding groove is fixedly connected to the pneumatic lifting assembly, and the guide sliding rod is slidingly arranged in the guide sliding groove.

[0014] The shearing assembly rises and falls along with the lifting of the fork, when the fork is located above, the driving lever and the driven lever cannot contact, at this time, even if the wheel hub is rotated and adjusted, the shearing action will not be triggered; when the fork is located below, the driving lever can push the driven lever and trigger the shearing action when it rotates.

[0015] Further, the shearing and stirring assembly comprises a reset spring piece, a driven lever and a driving lever, the reset spring piece is arranged between the guide sliding rod and the pneumatic lifting assembly, the driven lever is fixedly connected to the side surface of the guide sliding rod, the driving lever is provided with a fixed base, the fixed base is fixedly connected to the side surface of the wheel hub, and when the driving lever pushes the driven lever, the sliding shear can slide towards the fixed shear.

[0016] Through the rotating movement of the hub itself, the mute cotton tape can be automatically cut after the hub rotates one circle, and the mute cotton tape will not be pulled out in the subsequent rolling process.

[0017] According to different hub materials, the fixed base can be fixed on the hub by magnetic attraction, air pressure adsorption, clamping jaw and the like.

[0018] Further, the pneumatic lifting assembly comprises a longitudinal air cylinder, a fork, a shaft and an air cylinder valve, the longitudinal air cylinder is arranged on the feeding assembly, the fork is arranged on the push rod of the longitudinal air cylinder, the shaft is fixedly connected to the fork, the air cylinder valve is fixedly connected to the rack, the air cylinder valve and the longitudinal air cylinder are connected through a pipeline, and the gas pressure in the longitudinal air cylinder can be controlled through the air cylinder valve.

[0019] The pressure of the uniform pressure imitation form rolling assembly on the hub is related to the gas pressure in the longitudinal air cylinder, so no matter the profile of the inner wall of the hub or the diameter of the hub, as long as the gas pressure in the longitudinal air cylinder is constant during the rolling process, the rolling pressure is constant.

[0020] Further, the air shaft sleeve is sleeved on the shaft, the fixed shear is fixedly connected to the fork, the guide sliding groove is fixedly connected to both ends of the fork, and the reset spring plate is arranged between the guide sliding rod and the fork.

[0021] When the longitudinal air cylinder pushes down the fork, the pressure of the uniform pressure imitation form rolling assembly on the hub also increases the extrusion force and friction force between the hub and the adjustable rubber sleeve, thereby reducing the possibility of slipping when the support roller drives the hub to rotate, and different types of hubs can be adapted by adjusting the spacing of the adjustable rubber sleeve.

[0022] Further, the feeding assembly comprises a guide plate and a mute cotton tape, the guide plate is fixedly connected to the rack, the mute cotton tape is slidably arranged on one side of the guide plate, one side of the mute cotton tape in contact with the hub is provided with a back glue, and the longitudinal air cylinder is fixedly connected to the other side of the guide plate.

[0023] Further, the hub support assembly comprises a roller support, a support roller and an adjustable rubber sleeve, the roller support is arranged on the rack, the support roller is rotatably arranged in the roller support, the adjustable rubber sleeve is arranged on the support roller, and the adjustable rubber sleeve is in rolling contact with the hub.

[0024] The application also provides a use method of the hub mute cotton automatic attaching device, which specifically comprises the following steps:

[0025] Step 1: according to the width of the hub and the width of the mute cotton tape to be attached, the positions and spacing of the adjustable rubber sleeves are adjusted, then the hub is placed on the adjustable rubber sleeves, and the hub is supported by the four adjustable rubber sleeves.

[0026] Step two: manually pull out the mute cotton tape and paste the end on the inner wall of the hub, then control the longitudinal cylinder to extend through the cylinder valve, when the fork frame with the uniform pressure imitation form rolling assembly is lowered, the rubber tire will contact the mute cotton tape and press the inner wall of the hub, since each rolling wheel can independently slide longitudinally, the bearing will automatically adjust to the height suitable for the profile of the inner wall of the hub, since the air shaft sleeve has the uniform pressure feature, the downward pressure between each bearing and the hub is equal, thereby ensuring the uniformity of the rolling and pasting;

[0027] Step three: then drive the supporting roller to rotate through the electric or manual mode, since the longitudinal cylinder is pressed downward, the supporting roller can drive the hub to rotate under the action of friction;

[0028] Step four: in the rolling process, the mute cotton tape is gradually wound and wrapped on the inner wall of the hub, since the inner ring of the bearing does not rotate when the rolling wheel and the rubber tire rotate, the air shaft sleeve will not be continuously twisted;

[0029] Step five: when the hub starts to rotate, the driving lever is located at the position close to the driven lever, after the driving lever rotates for one revolution, it can push the driven lever, at the same time, the sliding shear is pushed to slide towards the fixed shear, thereby completing the shearing of the mute cotton tape; after the shearing is completed, the mute cotton tape below the shearing assembly will be continuously pasted on the hub, and the mute cotton tape above the shearing assembly will not be continuously pulled out;

[0030] Step six: then continue to drive the hub to rotate, and repeatedly roll the mute cotton tape through the uniform pressure imitation form rolling assembly, even if the shearing assembly is triggered, the mute cotton tape will not be cut off in the subsequent rolling process.

[0031] Step seven: after the pasting is completed, the longitudinal cylinder is controlled to rise and reset through the cylinder valve, then the hub can be taken out.

[0032] The beneficial effects obtained by the above structure are as follows:

[0033] (1) the air shaft sleeve has the uniform pressure feature, so that the downward pressure received by each bearing is equal, thereby maintaining the consistent downward pressure in the case that the offset amplitude of each rolling wheel relative to the shaft is different.

[0034] (2) the width of each rubber tire is relatively narrow, so even if different parts of the same rubber tire have different compression amounts due to the slope of the inner wall of the hub, the difference in elasticity is small, thereby ensuring that the pressure of the entire rolling surface is within a small fluctuation range.

[0035] (3) The shearing assembly is lifted along with the lifting of the fork, when the fork is at the top, the driving lever and the driven lever cannot contact, at this time, even if the hub is rotated and adjusted, the shearing action will not be triggered; when the fork is at the bottom, the driving lever can push the driven lever and trigger the shearing action when it rotates.

[0036] (4) Through the rotation of the hub itself, after the hub rotates one circle, the mute cotton belt can be automatically sheared, and in the subsequent rolling process, the mute cotton belt will not be pulled out again.

[0037] (5) According to different hub materials, the fixed base can be fixed on the hub by magnetic attraction, air pressure adsorption, clamping jaw and the like.

[0038] (6) The pressure of the uniform pressure imitation type rolling assembly on the hub is related to the pressure in the longitudinal cylinder, therefore, no matter how the profile of the inner wall of the hub is, and no matter how the diameter of the hub is, as long as the internal pressure of the longitudinal cylinder is constant during the rolling process, the pressure of the rolling is constant.

[0039] (7) When the longitudinal cylinder pushes the fork to descend, the pressure of the uniform pressure imitation type rolling assembly on the hub also increases the extrusion force and friction force between the hub and the adjustable rubber sleeve, thereby reducing the possibility of slipping when the support roller drives the hub to rotate, and by adjusting the distance of the adjustable rubber sleeve, different types of hubs can be adapted.

DETAILED DESCRIPTION

[0054] As Figures 1-10As shown, the application provides a wheel hub mute cotton automatic bonding device, which comprises an equalizing imitation form rolling assembly 1, a shearing assembly 2, a shearing and stirring assembly 3, a pneumatic lifting assembly 4, a wheel hub supporting assembly 5, a feeding assembly 6 and a rack 7, the equalizing imitation form rolling assembly 1 is arranged on the pneumatic lifting assembly 4, the shearing assembly 2 is arranged on the pneumatic lifting assembly 4, the shearing and stirring assembly 3 is arranged on the shearing assembly 2, the pneumatic lifting assembly 4 is arranged on the feeding assembly 6, the feeding assembly 6 is arranged on the rack 7, and the wheel hub supporting assembly 5 is arranged on the rack 7.

[0055] The equalizing imitation form rolling assembly 1 comprises an air shaft sleeve 11, bearings 12, rolling wheels 13 and rubber tires 14, the air shaft sleeve 11 is sleeved on the bottom of the pneumatic lifting assembly 4, the bearings 12 are arranged on the air shaft sleeve 11, the rolling wheels 13 are rotatably arranged on the bearings 12, and the rubber tires 14 are sleeved on the outside of the rolling wheels 13.

[0056] The air shaft sleeve 11 has the characteristic of equalizing pressure, so that the downward pressure of each bearing 12 is equal, thereby keeping consistent downward pressure in the case that the offset amplitudes of each rolling wheel 13 relative to the shaft 43 are different.

[0057] The side surfaces of each group of rolling wheels 13 are in contact and can slide relative to each other, so that even if the groups of bearings 12 are not coaxial, the central axes of the groups of bearings 12 are still parallel to each other.

[0058] The width of each rubber tire 14 is relatively narrow, so that even if different parts of the same rubber tire 14 have different compression amounts due to the slope of the inner wall of the wheel hub, the difference in elasticity is relatively small, thereby ensuring that the pressure of the entire rolling surface is within a relatively small fluctuation range.

[0059] The shearing assembly 2 comprises fixed shearing legs 21, sliding shearing legs 22, guide sliding grooves 23 and guide sliding rods 24, the fixed shearing legs 21 are fixedly connected to the pneumatic lifting assembly 4, the sliding shearing legs 22 are fixedly connected to the guide sliding rods 24, the guide sliding grooves 23 are fixedly connected to the pneumatic lifting assembly 4, and the guide sliding rods 24 are slidingly arranged in the guide sliding grooves 23.

[0060] The shearing assembly 2 rises and falls following the lifting of the fork 42, when the fork 42 is located at the upper position, the driving stirring rod 33 and the driven stirring rod 32 cannot be in contact, at this time, even if the wheel hub is rotated and adjusted, the shearing action cannot be triggered; when the fork 42 is located at the lower position, the driving stirring rod 33 can push the driven stirring rod 32 and trigger the shearing action when the driving stirring rod 33 rotates.

[0061] The shearing and pushing assembly 3 comprises a reset spring sheet 31, a driven pushing rod 32 and a driving pushing rod 33. The reset spring sheet 31 is arranged between the guide sliding rod 24 and the pneumatic lifting assembly 4. The driven pushing rod 32 is fixedly connected to the side of the guide sliding rod 24. The driving pushing rod 33 is provided with a fixed base 331. The fixed base 331 is fixedly connected to the side of the wheel hub. When the driving pushing rod 33 pushes the driven pushing rod 32, the sliding shear 22 can slide towards the fixed shear 21.

[0062] Through the rotation of the wheel hub itself, the mute cotton belt 62 can be automatically sheared after the wheel hub rotates one round. In the subsequent rolling process, the mute cotton belt 62 will not be pulled out again.

[0063] According to different wheel hub materials, the fixed base 331 can be fixed on the wheel hub by magnetic attraction, air pressure adsorption, clamping jaw and the like.

[0064] The pneumatic lifting assembly 4 comprises a longitudinal air cylinder 41, a fork 42, a shaft 43 and an air cylinder valve 44. The longitudinal air cylinder 41 is arranged on the feeding assembly 6. The fork 42 is arranged on the push rod of the longitudinal air cylinder 41. The shaft 43 is fixedly connected to the fork 42. The air cylinder valve 44 is fixedly connected to the rack 7. The air cylinder valve 44 and the longitudinal air cylinder 41 are connected by a pipeline. The air pressure in the longitudinal air cylinder 41 can be controlled by the air cylinder valve 44.

[0065] The pressure of the uniform pressure and simulation form rolling assembly 1 on the wheel hub is related to the air pressure in the longitudinal air cylinder 41. Therefore, as long as the air pressure in the longitudinal air cylinder 41 is constant during the rolling process, the rolling pressure is constant, regardless of the profile of the inner wall of the wheel hub or the diameter of the wheel hub.

[0066] The air shaft sleeve 11 is sleeved on the shaft 43. The fixed shear 21 is fixedly connected to the fork 42. The guide sliding groove 23 is fixedly connected to the two ends of the fork 42. The reset spring sheet 31 is arranged between the guide sliding rod 24 and the fork 42.

[0067] When the longitudinal air cylinder 41 pushes the fork 42 to descend, the pressure of the uniform pressure and simulation form rolling assembly 1 on the wheel hub also increases the extrusion force and friction force between the wheel hub and the adjustable rubber sleeve 53, thereby reducing the possibility of slipping when the supporting roller 52 drives the wheel hub to rotate. By adjusting the spacing of the adjustable rubber sleeve 53, different types of wheel hubs can be adapted.

[0068] The feeding assembly 6 comprises a guide plate 61 and a mute cotton belt 62. The guide plate 61 is fixedly connected to the rack 7. The mute cotton belt 62 is slidably arranged on one side of the guide plate 61. The side of the mute cotton belt 62 in contact with the wheel hub is provided with a back glue. The longitudinal air cylinder 41 is fixedly connected to the other side of the guide plate 61.

[0069] The hub supporting assembly 5 comprises a roller support 51, a supporting roller 52 and an adjustable rubber sleeve 53, the roller support 51 is arranged on the frame 7, the supporting roller 52 is rotatably arranged in the roller support 51, and the adjustable rubber sleeve 53 is arranged on the supporting roller 52, and the adjustable rubber sleeve 53 is in rolling contact with the hub.

[0070] In specific use, first, the user needs to adjust the position and spacing of the adjustable rubber sleeve 53 according to the width of the hub and the width of the mute cotton tape 62 to be pasted, and then places the hub on the adjustable rubber sleeve 53, and supports the hub through the four adjustable rubber sleeves 53.

[0071] The user manually pulls out a small section of the mute cotton tape 62 and pastes the end on the inner wall of the hub, and needs to ensure that the mute cotton tape 62 exists directly below the uniform pressure and simulation form rolling assembly 1, and then controls the longitudinal cylinder 41 to extend through the cylinder valve 44, and under the air pressure control of the cylinder valve 44, the internal pressure of the longitudinal cylinder 41 will be maintained near a stable value.

[0072] When the fork frame 42 descends with the uniform pressure and simulation form rolling assembly 1, the rubber tire 14 will contact the mute cotton tape 62 and extrude the inner wall of the hub, and since each rolling wheel 13 can independently slide longitudinally, the bearing 12 will automatically adjust to a height suitable for the profile of the inner wall of the hub, and since the air shaft sleeve 11 has the uniform pressure feature, the downward pressure between each bearing 12 and the hub is equal, thereby ensuring the uniformity of rolling and pasting.

[0073] The width of each rubber tire 14 is relatively narrow, so even if different parts of the same rubber tire 14 have different compression amounts due to the slope of the inner wall of the hub, the difference in elasticity is relatively small, thereby ensuring that the pressure of the entire rolling surface is within a relatively small fluctuation range.

[0074] Then, the supporting roller 52 is driven to rotate slowly and uniformly by an electric or manual method, and since the longitudinal cylinder 41 is pressed downward, the hub and the adjustable rubber sleeve 53 also have a relatively large extrusion force, so the supporting roller 52 can stably drive the hub to rotate.

[0075] During the rolling process, the mute cotton tape 62 gradually winds and wraps on the inner wall of the hub, and since the inner ring of the bearing 12 does not rotate when the rolling wheel 13 and the rubber tire 14 rotate, the air shaft sleeve 11 will not be continuously twisted.

[0076] When the hub starts to rotate, the driving lever 33 is located close to the driven lever 32, and after the driving lever 33 rotates one circle, it can push the driven lever 32, and at the same time, push the sliding shear 22 to slide towards the fixed shear 21, to complete the shearing of the mute cotton tape 62; after the shearing is completed, the mute cotton tape 62 located below the shearing assembly 2 will be continuously pasted on the hub, and the mute cotton tape 62 located above the shearing assembly 2 will not be continuously pulled out;

[0077] Then continue to drive the hub to rotate for several circles, and through the uniform pressure imitation form rolling assembly 1, repeatedly roll the mute cotton tape 62, and in the subsequent rolling process, even if the shearing assembly 2 is triggered, it will not cut off the mute cotton tape 62.

[0078] After the pasting is completed, after the longitudinal air cylinder 41 is controlled to rise and reset through the air cylinder valve 44, the hub can be taken off.

[0079] It should be noted that in this text, the relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between the entities or operations. Moreover, the term "includes", "contains" or any other variant thereof is intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.

[0080] The above describes the present application and its embodiments, which is not restrictive, and the drawings shown are only one of the embodiments of the present application, and the actual structure is not limited thereto. In general, if a person skilled in the art is inspired by it, without departing from the purpose of the present application, without creative design, similar structure and embodiments of the technical solution can be designed, which should belong to the protection scope of the present application.
