Description

Technical Field

[0001] The present invention belongs to the technical field of automotive parts, and particularly relates to brake assembly technology.

Background Art

[0002] During the manufacturing process of brakes, the sealing ring in the caliper is a crucial component. In traditional assembly stations, only manual assembly is carried out. After assembly, it is smeared in a circle with fingers and then the next process is carried out. Therefore, high requirements are imposed on the assembly techniques of employees. If the sealing ring is not assembled in place, it is likely to cause damage to the sealing ring in subsequent assembly processes, thus affecting product quality and increasing production costs. Therefore, it is necessary to set up a special sealing ring rolling device to roll the manually assembled sealing ring to reduce the unstable factors occurring during manual assembly.

[0003] In addition, there are various products with different specifications for brakes. For some products, the shield needs to be press-fitted (without rolling the sealing ring), and for some products, the sealing ring needs to be rolled (without press-fitting the shield). If the shield press-fitting and the sealing ring rolling need to be completed respectively, a shield press-fitting device and a sealing ring rolling device need to be set up separately. However, when changing products, different devices need to be replaced, which not only has a high cost but also takes time during the replacement process, affecting the efficiency of the production line.

[0019] The brake caliper shield pressing and sealing ring rolling device of the present invention integrates multiple products on the production line. For some products, the shield needs to be pressed (without rolling the sealing ring), and for some products, the sealing ring needs to be rolled (without pressing the shield). Therefore, the shield pressing and detecting component and the sealing ring rotating and rolling component can be replaceably installed. When the shield needs to be pressed, it is replaced with the shield pressing and detecting component.

Detailed implementation manners

[0033] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings of the embodiments of the present invention. However, the following embodiments are only the preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present invention.

[0034] Those skilled in the art can understand that, without conflict, the features in the following embodiments and implementation manners can be combined with each other.

[0035] The terms used in the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. For example, the terms such as "upper", "lower", "transverse" and the like indicating orientation or positional relationship are only based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device / element referred to must have a specific orientation or be constructed and operated in a specific orientation, and thus cannot be understood as a limitation to the present invention.

[0036] In the present invention, unless otherwise clearly specified and limited, the first feature being "above" or "below" the second feature may include direct contact between the first and second features, or may include indirect contact between the first and second features through additional features therebetween. Moreover, the first feature being "above", "over" and "on" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the first feature has a higher horizontal height than the second feature. The first feature being "below", "under" and "beneath" the second feature includes the first feature being directly below and obliquely below the second feature, or merely indicating that the first feature has a lower horizontal height than the second feature.

[0037] Referring to Figures 1 to 8 As shown, this embodiment provides a brake caliper shield pressing and seal ring rolling device. Since the production line where this device is located integrates multiple products, some of which require shield pressing (without rolling the seal ring), and some other products require rolling the seal ring (without pressing the shield), this device includes a replaceably mountable shield pressing and detecting member 2 and a seal ring rotary rolling member 1.

[0038] Among them, the shield press-fitting detection component 2 includes a shield pressing head 25, and a shield positioning structure for positioning the shield 200 is provided on the shield pressing head 25; the sealing ring rotary rolling component 1 includes a rotary driver, a rolling arm 12 driven by the rotary driver to rotate, and a rolling member connected to the upper end of the rolling arm. The rolling member rotates following the rolling arm 12 and rolls the inner ring of the sealing ring during rotation. Usually, rolling the sealing ring two to three circles is sufficient.

[0039] In addition, a lifting driver 3 is further provided. The lifting driver 3 includes a servo electric cylinder 31 and a lifting component. The servo electric cylinder 31 drives the lifting component to move linearly up and down, and the lifting component drives the sealing ring rotary rolling component 1 or the shield press-fitting detection component 2 to lift, so as to lift the sealing ring rotary rolling component 1 or the shield press-fitting detection component 2 to the working height, or lower it to the non-working height.

[0040] Since the shield press-fitting detection component and the sealing ring rotary rolling component can be replaceably installed, when it is necessary to press-fit the shield, it is replaced with the shield press-fitting detection component. When it is necessary to roll the sealing ring, the shield press-fitting detection component is replaced with the sealing ring rotary rolling component. In this way, both shield press-fitting and sealing ring rotary rolling can be carried out, flexible production can be achieved, the equipment is reduced, and the cost is lowered.

[0041] The servo electric cylinder is used to drive the shield press-fitting detection component to move linearly up and down, realizing the precise press-fitting of the shield and the precise alignment of the rolling member with the inner ring of the sealing ring, thereby ensuring the rolling effect of the sealing ring.

[0042] In this embodiment, the rotary driver is a rotary clamping cylinder 11, and the two rolling arms 12 are driven by the rotary clamping cylinder 11 to open, close and rotate. The two rolling arms 12 rotate after opening to roll the inner ring of the sealing ring; after the two rolling arms 12 are closed, they rise to enter the inner side of the sealing ring to prepare for rolling the sealing ring, or after the rolling of the sealing ring is completed, they disengage from the contact with the inner ring of the sealing ring, descend and leave the inner side of the sealing ring. The cooperation of the rotary clamping cylinder 11 and the two rolling arms 12, combined with the precise up and down movement of the servo electric cylinder in the lifting driver, enables the precise alignment of the rolling member with the inner ring of the sealing ring in the axial and radial directions, thereby realizing the precise rolling of the manually assembled sealing ring. Through the above design, the unstable factors occurring during manual assembly are significantly reduced, the damage rate of the sealing ring is reduced at the same time, and the qualification rate of the subsequent workstations is improved.

[0043] Preferably, the rolling member is a cam follower 13, and the two cam followers 13 are respectively installed at the upper ends of the two rolling arms 12. The cam follower has a roller, and the roller rolls in contact with the inner ring of the sealing ring to roll the inner ring of the sealing ring, having a good rolling effect.

[0044] It is understandable that both the rotary clamping cylinder and the cam follower can be directly purchased from the market.

[0045] In some embodiments, the shield press-fitting detection component 2 includes a base 21, a shield press shaft 22 movably connected to the base, a pressure sensor 23 disposed between the lower end of the shield press shaft and the base, and the shield press head 25 is disposed at the upper end of the shield press shaft. In addition, a linear bearing 24 is provided between the shield press shaft 22 and the base 21. Among them, the pressure sensor 23 can detect the real-time pressure of the shield being pressed in to ensure accurate press-fitting.

[0046] Specifically, the shield positioning structure is a positioning groove 251, and the inner circle of the positioning groove is elastically buckled with the outer circle of the shield, so as to keep the shield positioned reliably and facilitate the realization of shield press-fitting.

[0047] In some embodiments, the lifting driver further includes a guiding bracket, the guiding bracket includes a bottom plate 33, a top plate 34 and guiding rods 35 disposed between the bottom plate and the top plate, the lifting component includes a lifting member, and the lifting member 32 is guidingly connected to the guiding rods 35. Specifically, the lifting member is a lifting plate, and a guiding sleeve 36 is provided between the lifting member 32 and the guiding rods 35. The guiding sleeve is fixed to the lifting plate by a flange. The output end of the servo electric cylinder is connected with a lower joint, and the lower joint is fixed to the lifting plate by bolts.

[0048] Furthermore, the brake caliper shield press-fitting and seal ring rolling device further includes an interchangeable mounting component 4. The interchangeable mounting component 4 includes a base plate 41 at the bottom and a mounting seat 42 at the top. The mounting seat 42 is rectangular, and mounting holes are provided at the four corners for connecting mounting bolts to connect with the shield press-fitting detection component 2 or the seal ring rotary rolling component 1. The base plate 41 is also rectangular, and mounting holes are provided at the four corners for connecting mounting bolts for connecting with the lifting member 32.

[0049] In addition, the brake caliper shield press-fitting and seal ring rolling device further includes a transverse moving component 5 for realizing the transverse movement of the device. The transverse moving component 5 includes a transverse moving cylinder, a transverse guide rail and a transverse moving slider, and the transverse moving cylinder drives the transverse moving slider to slide transversely along the transverse guide rail. The whole device is moved to the working position by driving of the transverse moving cylinder.

[0050] As described above, only the specific embodiments of the invention are provided, but the protection scope of the invention is not limited thereto.
