[0001] The present invention relates to a sealing ring installation device, in particular to a sealing ring installation tool. Background Art

[0002] A vehicle's brake caliper is a component that applies force to the brake disc. The hydraulic pressure generated by the master brake cylinder ultimately acts on the piston inside the caliper, which expands and pushes the brake pads toward the disc. The production of vehicle brake calipers involves installing the sealing ring within the sealing groove inside the caliper. Currently, this process is either performed entirely manually by an operator or semi-automatically with the assistance of automated machinery. Regardless of the method used, the operator must manually pre-place the sealing ring within the caliper assembly to complete the entire installation process. This operation is cumbersome and inefficient. Therefore, a sealing ring installation tool is needed to assist operators or automated machinery in conveniently installing the sealing ring within the caliper, thereby improving the efficiency of sealing ring installation. Summary of the Invention

[0003] In order to solve the above technical problems, an object of the present invention is to provide a sealing ring installation tool that can conveniently install the sealing ring inside the caliper to improve the sealing ring installation efficiency.

[0004] The sealing ring installation tool of the present invention comprises a ring seat and a ring hook, wherein the ring hook comprises a hook portion and a handle connected to the hook portion, a hook groove capable of accommodating the hook portion is provided on the ring seat, and positioning blocks are respectively provided on both sides of the hook groove.

[0005] Furthermore, in the sealing ring installation tool of the present invention, a positioning cover is provided above the ring seat, and the positioning block is respectively connected to the ring seat and the positioning cover.

[0006] Furthermore, in the sealing ring installation tool of the present invention, the positioning cover is provided with an air injection hole.

DETAILED DESCRIPTION

[0032] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0033] See also Figures 1 to 14 A sealing ring installation tool of the present invention includes a ring seat 1 and a ring hook 2. The ring hook includes a hook portion 201 and a handle portion 202 connected to the hook portion. The ring seat is provided with a hook groove 3 that can accommodate the hook portion, and positioning blocks 4 are respectively provided on both sides of the hook groove.

[0034] The arrangement of the ring seat, ring hook, and positioning blocks facilitates the placement of the sealing ring 6 within the caliper by an operator or automated equipment. During use, the sealing ring is manually or automatically placed on top of the ring seat. The hook portion of the ring hook is then manually or automatically moved toward the sealing ring until it exerts a certain pressure on the sealing ring. Under the action of this pressure, the sealing ring deforms to a certain extent and sinks inward between the positioning blocks on both sides. The operator or automated equipment then places the ring seat with the sealing ring below the caliper opening and moves it upward until the sealing ring and the sealing groove are at the same level. At this point, the hook portion is approximately located in the middle of the caliper cavity. The caliper is then manually or automatically moved downward to the middle and lower portion of the hook groove to restore the sealing ring within the caliper to its original shape. The restored sealing ring is approximately located in the sealing groove. The operator or automated equipment then moves the hook portion upward using the handle until it rises again to the height of the sealing ring. The hook portion can then be manually or automatically moved left and right to firmly press the sealing ring into the sealing groove. Once the sealing ring is fully seated in the sealing groove, the ring seat and hook can be withdrawn from the caliper, ready for the next installation. The ring seat is used to position the sealing ring and align it with the caliper housing, matching the inner cavity of the caliper. The hook portion of the hook is used to apply pressure to the sealing ring from the outside, causing it to deform so that it can easily enter the caliper. It also applies pressure from the inside of the sealing ring to quickly and completely enter the sealing groove. The groove allows the hook to rise and fall within the groove to achieve the aforementioned movement of the hook portion. The setting of the positioning block plays a role in shaping the sealing ring. Specifically, in the natural state, there is a certain gap between the inner side of the sealing ring and the outer side of the positioning block. After the hook applies pressure to the sealing ring, part of the sealing ring enters into the gap between the positioning blocks on both sides thereof under the action of the pressure until the inner side of the sealing ring is in close contact with the outer side of the positioning block. At this time, the sealing ring is in a deformed state, there is no gap between the sealing ring and the positioning block, and its overall diameter becomes smaller, so that it can enter the interior of the caliper and move to the positioning groove.

[0035] Preferably, a positioning cover 7 is provided above the ring seat, and the positioning blocks are connected to the ring seat and the positioning cover respectively.

[0036] The positioning cover ensures the sealing ring is positioned properly. Since the sealing ring exhibits significant elasticity after deformation, it could potentially fall off the top of the positioning block during movement of the ring seat. However, the positioning block, located on the bottom surface of the positioning cover and with its outer side positioned inboard of the edge of the positioning cover, prevents the sealing ring from falling off the positioning block. In practice, there are two positioning blocks, both integrally formed with the positioning cover and connected to the ring seat via screws. When the hook applies pressure to the sealing ring, the hook drives the sealing ring into the space between the two positioning blocks until it contacts the inner side of the positioning blocks, thereby achieving positioning and shaping of the sealing ring. In practice, the inner side of the positioning block is a curved surface. During operation, the sealing ring slides from above the positioning cover onto the outer sides of the two positioning blocks. A clearance groove 8 can be provided on the bottom surface of the positioning cover to clear the tip of the hook, allowing it to fully contact the sealing ring.

[0037] Preferably, an air injection hole 9 is provided on the positioning cover.

[0038] The provision of the air jet holes not only allows the positioning cover to position the sealing ring, but also, during the installation process, the gas ejected from the air jet holes can exert a certain pressure on the inner side of the sealing ring, allowing it to better enter the sealing groove. Specifically, the air jet holes can be located on the outer side of the positioning block, and the entire positioning cover is provided with four air jet holes. The air jet holes are connected to an external high-pressure air source through a channel within the positioning cover. The high-pressure air source can supply air to the sealing ring throughout the installation process. The frequency and duration of the air supply can be adjusted according to the specific model of the caliper.

[0039] Preferably, a ring support 10 is provided on the outer side of the ring seat.

[0040] The ring support provides support for the sealing ring. It is an annular structure with a ring seat provided with a cutout 11 or opening for the ring hook to enter and exit. It can be mounted directly on the ring seat or connected to a mounting base 12 for the ring seat. During operation, the sealing ring is positioned above the ring support, and the hook enters and exits the ring seat through the cutout or opening in the ring support.

[0041] Preferably, the sealing ring installation tool further includes a mounting seat 12, on which a ring seat is arranged. An air inlet 13 is arranged on the mounting seat, and an air duct 14 connecting the air inlet and the air jet hole is arranged inside the ring seat.

[0042] The mounting base facilitates both the installation of the ring seat and the supply of air to the air jet. Specifically, the ring seat is fixed to the mounting groove on the surface of the mounting base with screws. The air inlet is located on the bottom surface of the mounting base. The air passage includes an arcuate connecting groove 1401 located on the bottom surface of the ring seat. The bottom of the arcuate connecting groove is provided with a through hole 1402 extending from the bottom surface of the arcuate connecting groove to the surface of the ring seat. The bottom surface of the positioning cover or positioning block is provided with a connecting hole 15. One end of the connecting hole is connected to the air jet, and the other end is connected to the through hole in the ring seat, thereby supplying air to the air jet.

[0043] Preferably, the sealing ring installation tool further includes a first bushing shell 16 , one end of the mounting seat is fixed on the first bushing shell, a limit block 17 is provided above the first bushing shell, and the limit block is connected to the ring support through a connecting plate 18 .

[0044] The provision of the first bushing housing enables the installation of components such as the mounting base and ring support on the seal ring drive platform, thus achieving automated operation of the seal ring. In specific implementation, the first bushing housing and the stop block are connected by a first linear bushing 19, with a certain gap between them. Notches 20 are correspondingly provided at the top of the first bushing housing and the bottom of the stop block to allow the handle to enter and exit. The stop block also functions as a limiter for the hook.

[0045] Preferably, it also includes a sealing ring driving platform, which includes a support frame 21, a base plate 22 that can be translated laterally along the first slide rail on the support frame surface, a base plate driving device 33 that drives the base plate to be translated along the first slide rail 23, an intermediate plate 25 that can be translated vertically along the second slide rail 24 on the base plate surface, an intermediate plate driving device 26 that drives the intermediate plate to be translated vertically along the second slide rail, a top plate 28 that can be translated laterally along the third slide rail 27 on the intermediate plate surface, a top plate driving device 29 that drives the top plate to be translated along the third slide rail, a hook lifting device 30 that is arranged on the top plate and has an output end connected to the handle, a mounting plate 31 is provided at one end of the intermediate plate, and the first bushing shell is fixed on the mounting plate.

[0046] The support frame supports and mounts the various structural components. The bottom plate drive mechanism drives the bottom plate horizontally, enabling the bottom plate and its components, including the ring seat, to move laterally, ultimately allowing the ring seat to reach below the caliper opening. The intermediate plate drive mechanism drives the intermediate plate vertically, allowing the intermediate plate and its components to move up and down, allowing the ring seat on the mounting plate to enter the caliper and raise the sealing ring to the height of the sealing groove. The top plate drive mechanism drives the top plate horizontally, enabling the handle connected to the top plate to drive the hook to move left and right, thereby applying pressure to the sealing ring from both the inside and outside, thereby deforming the sealing ring and securing it within the sealing groove. The setting of the ring hook lifting device realizes the lifting function of the ring hook, so that it can drive the hook part of the ring hook to rise and fall. When the hook part needs to squeeze the sealing ring to deform it, the ring hook lifting device drives the ring hook until the hook part is at the same height as the sealing ring; when the ring seat enters the caliper and the sealing ring is at the height of the sealing groove, the ring hook lifting device can drive the hook part to descend so that the sealing ring can restore its original shape and enter the sealing groove; when the sealing ring roughly enters the sealing groove, the ring hook lifting device can drive the hook part to rise to the height of the sealing groove or the sealing ring, and cooperate with the top plate driving device. The hook part can move left and right in the plane where the sealing ring is located, so that it generates pressure on the inner side of the sealing ring, and thus enables it to completely enter the sealing groove.

[0047] During operation, the top plate, driven by the top plate drive, moves toward the ring seat until the hook squeezes and deforms the sealing ring. After the sealing ring is deformed, the bottom plate drive drives the bottom plate toward the caliper until the ring seat moves below the caliper opening. The middle plate drive then raises the middle plate until the ring seat enters the caliper through the lower opening. At this point, the sealing ring is at the height of the sealing groove. The hook then descends, driven by the hook lifter, releasing the sealing ring. After release, the sealing ring returns to its original shape and roughly enters the sealing groove. The hook then rises again, driven by the hook lifter, to the height of the sealing groove. The middle plate drive then drives the middle plate left and right, driving the hook left and right, causing it to squeeze the inside of the sealing ring and fully enter the sealing groove. Once the sealing ring is installed, the components are returned to their original positions, driven by the drive and lifters. Before the sealing ring enters the sealing groove and the ring seat returns to its original position, an external air source can continuously or intermittently release air to the sealing ring through the air injection holes on the side of the positioning cover to further press the sealing ring into the sealing groove. Among them, the bottom plate drive device, the middle plate drive device, the top plate drive device and the circle hook lifting device are all linear displacement drive devices, which can be automated mechanical devices with linear displacement drive capabilities such as cylinders, oil cylinders or linear drive motors.

[0048] Preferably, a buffer 32 or a limiter is provided on the support frame.

[0049] The setting of the buffer realizes the buffering function of the bottom plate, which can prevent the bottom plate and the support frame from being violently collided. and While this device may cause some damage to the support frame, base plate, and its components, it also allows for the positioning of the base plate and ring seat, allowing the ring seat to be accurately moved to the caliper opening under the drive of the base plate drive. Furthermore, it can be replaced with a limiter (such as a proximity switch), allowing an external controller (such as a PLC) to provide feedback control to the various drive devices via the limiter signals, thereby achieving base plate positioning and buffering functions. The buffer is preferably a hydraulic buffer.

[0050] Preferably, the top plate driving device includes a driving motor 2901 arranged on the middle plate of the machine body, a synchronous belt 2902 engaged with the synchronous wheel on the output shaft of the driving motor, and a connecting plate 2903 fixedly connected to the synchronous belt, and the connecting plate is also fixedly connected to the top plate.

[0051] The drive motor and other components drive the top plate and its hooks. During operation, the output shaft of the drive motor rotates the synchronous pulleys, which in turn rotate the synchronous belt meshing with the synchronous pulleys around the two synchronous pulleys mounted on the middle plate. As the synchronous belt rotates, the connecting plate attached to the synchronous belt moves between the front and rear synchronous pulleys, thereby driving the top plate, hooks, and other components.

[0052] Preferably, the bottom plate driving device, the middle plate driving device, and the hook lifting device are all cylinders.

[0053] Preferably, the support frame includes a base plate 2101, a rib plate 2102 with its bottom end arranged on the surface of the base plate, a support plate 2103 located above the base plate and fixed to the rib plate, the buffer is arranged on the rib plate, and the first slide rail is arranged on the surface of the support plate.

[0054] Preferably, a second bushing shell 34 is further provided on the surface of the top plate, a second linear bushing is provided in the second bushing shell, and the top end of the second linear bushing is connected to the handle of the loop hook.

[0055] The provision of the second bushing housing guides the hook handle, enabling it to be raised and lowered synchronously and linearly with the output end of the hook lifting device. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that those skilled in the art will be able to implement the invention in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive, and the scope of protection of the invention is defined by the appended claims rather than the foregoing description.

[0056] In addition, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present invention.
