Description

Technical Field

[0001] This application relates to the field of automotive technology, and in particular to a guiding mechanism and pressing equipment. Background Technology

[0002] Automobile calipers provide a parking function for vehicles. A caliper includes a piston, a drive linkage assembly (comprising a screw and a nut fitted onto the screw) that floats relative to the piston, an actuator, and a caliper body. The actuator drives the screw and sleeve to move, which in turn pushes the piston to engage friction plates mounted on the caliper, gripping the brake pads to achieve the parking function.

[0003] The assembly precision of caliper pistons is relatively high. During the pressing process of the caliper piston into the caliper body, cumulative errors can easily lead to deviations in the coaxiality between the piston and its transmission connecting components and the caliper body, resulting in assembly defects. These cumulative errors include at least one of the following: caliper design tolerances, tooling design tolerances, tooling machining errors, and tooling assembly errors. Utility Model Content

[0011] Optionally, the floating component further includes:

[0012] A rolling element is mounted between the floating shaft and the inner wall of the mounting cavity via a mounting structure. The rolling element can roll relative to the floating shaft and the inner wall of the mounting cavity under the drive of the floating shaft.

[0013] Optionally, the outer peripheral wall of the floating shaft is provided with a first outer flange, the first outer flange being located within the mounting cavity along the axial direction of the guide rod. The inner wall surface of the mounting cavity includes a top surface near the driving component and a bottom surface near the guide rod. The mounting structure includes:

[0014] A first mounting groove is disposed on at least one of the first outer flange and the bottom surface.

[0019] Optionally, along the radial direction of the guide rod, the floating shaft has a first position relative to the housing that is offset from the central axis of the mounting cavity and a second position that is coaxial with the mounting cavity, and the floating assembly further includes:

[0020] A reset component is disposed between the floating shaft and the inner wall of the mounting cavity, and the reset component can drive the floating shaft to reciprocate between the first position and the second position; and / or,

During the process of pressing the piston of the caliper into the caliper body, the guide rod will be coaxially connected with the screw connected to the piston and drive the screw and piston into the caliper body. Since the guide rod can float radially under the drive of the floating component, even if there is a difference between the piston and the transmission connection kit (screw and nut) and the central axis of the caliper body, the floating guide rod can drive the piston and the transmission connection kit to adaptively deflect to the center position of the caliper body, eliminating the assembly deviation caused by the cumulative error in the caliper assembly process, so as to avoid the internal force generated between the caliper body and the guide rod and damage to the caliper. Secondly, the floating distance of the floating component is easy to control, and it is not easy to cause the guide rod to wobble too much or too little and fail to play a guiding role. Therefore, once the floating component sets the predetermined floating distance of the guide rod, it will not cause the caliper to fail to be guided or damaged due to human reasons. Furthermore, the overall structure composed of floating components and guiding components has low complexity, is efficient and convenient to assemble, and is easy to promote and apply widely.

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0044] Currently, during the process of driving the piston 41 to press into the clamp body 43 by connecting the guide rod 12 to the transmission connection kit 42 of the caliper 40, in order to ensure that the caliper 40, the tooling connected to the guide rod 12 and the guide rod 12 can be aligned, and thus ensure the coaxiality between the piston 41, the transmission connection kit 42 and the clamp body 43, the fixing screws connecting the guide rod 12 to the tooling are usually loosened so that the guide rod 12 can wobble, thereby ensuring the coaxiality between the various components of the caliper 40 during assembly and avoiding the problem of damage to the caliper 40 due to the internal force generated between the caliper 40 and the guide rod 12.

[0045] However, currently, to ensure the coaxiality of the various components of the caliper 40 during assembly, the method of loosening the fixing screws of the guide rod 12 is used. However, it is difficult to control the degree of loosening. Excessive loosening can cause the guide rod 12 to wobble significantly, failing to achieve its guiding function. Even with only slight loosening, the caliper 40 may lack sufficient self-adaptive capability during assembly, leading to coaxiality deviations. Internal forces may still be generated between the guide rod 12 and the caliper 40, potentially damaging the caliper 40.

[0046] The first embodiment of this application provides a guiding mechanism, which is at least provided in the pressing device of the caliper 40. This guiding mechanism cooperates with the pressing mechanism of the pressing device to press the piston 41, connected to the transmission connection kit 42, into the caliper body 43 of the caliper 40, ultimately obtaining a caliper 40 product that meets coaxial accuracy. The caliper 40 mentioned in this application may include at least one of an EPB caliper 40 and an EMB caliper 40. Specifically, the EPB caliper 40 is an electronic parking brake caliper 40, and the EMB caliper 40 is an electro-mechanical brake caliper 40.

[0047] Please see Figures 1 to 6 The guiding mechanism in this application includes a guiding component 10 and a floating component 20. For example... Figure 1As shown, the guide assembly 10 includes a drive component 11 and a guide rod 12. The drive component 11 is connected to one end of the guide rod 12 and can drive the guide rod 12 to move linearly along its own axis. The other end of the guide rod 12 is used for at least coaxial connection with the transmission connection kit 42 of the caliper 40. If the transmission connection kit 42 includes a screw and a nut sleeved on the screw, a connecting hole is provided in the middle of the screw along its own axis. The end of the guide rod 12 away from the drive component 11 passes through the connecting hole, so that the guide rod 12 and the screw can be coaxially connected together.

[0048] The floating component 20 is installed between the drive component 11 and the guide rod 12 and can drive the guide rod 12 to float radially a predetermined distance. This predetermined distance can be specifically set according to different models of the caliper 40. In some embodiments of this application, the predetermined distance can be between 1.5mm and 2.5mm (unit: millimeters). Specifically, the predetermined distance can include one of the following: 1.5mm, 1.6mm, 1.7mm, 1.78mm, 1.8mm, 1.86mm, 1.9mm, 2.0mm, 2.05mm, 2.1mm, 2.2mm, 2.3mm, 2.4mm, 2.5mm, or any other value between 1.5mm and 2.5mm. This application does not impose a single limitation on this value.

[0049] In this application, when assembling the caliper 40, after the caliper body 43 is placed in the assembly position on the press-fitting equipment, the piston 41 can be pressed against by the press-fitting equipment's pressure head, and the transmission connection kit 42 can be gripped by the press-fitting equipment's robotic arm. After the guide rod 12 is coaxially connected to the screw of the transmission connection kit 42, the robotic arm is released. During the process of the press-fitting equipment driving its pressure head to press the piston 41 into the caliper body 43, the drive component 11 drives the guide rod 12 to move linearly. During this process, if there is a slight difference between the piston 41 and the transmission connection kit 42 and the central axis of the caliper body 43, the floating component 20 can drive the guide rod 12 to adaptively guide the piston 41 and the transmission connection kit 42 to the center position of the caliper body 43 in the direction of force, thereby enabling the guide rod 12 to drive the piston 41 and the transmission connection kit 42 to be on the same central axis as the caliper body 43, eliminating the internal force generated between the caliper 40 assembly process and the guide rod 12, and avoiding damage to the caliper 40.

[0050] Furthermore, since the predetermined distance by which the floating component 20 drives the guide rod 12 to float is fixed, there is no problem of excessive or insufficient wobbling of the guide rod 12 that occurs when using loose screws. Moreover, the floating component 20 is installed between the drive component 11 and the guide rod 12, enabling the guide rod 12 to adaptively guide the coaxiality of the various components of the caliper 40, while also reducing the overall structural complexity of the guiding mechanism and making assembly convenient and efficient.

[0051] As can be seen, in this application, the guiding mechanism includes a guiding component 10 and a floating component 20. The floating component 20 is installed between the driving component 11 and the guide rod 12 of the guiding component 10 and can drive the guide rod 12 to float a predetermined distance radially. During the process of pressing the piston 41 of the caliper 40 into the caliper body 43, the guide rod 12 will be coaxially connected to the screw connected to the piston 41 and drive the screw and piston 41 into the caliper body 43. Since the guide rod 12 can float radially under the drive of the floating component 20, even if there is a difference between the piston 41 and the transmission connection kit 42 (screw and nut) and the central axis of the caliper body 43, the piston 41 and the transmission connection kit 42 can be adaptively deflected to the center position of the caliper body 43 based on the floating guide rod 12, eliminating the assembly deviation caused by the cumulative error of the caliper 40 assembly process, so as to avoid the internal force generated between the caliper body 43 and the guide rod 12 and damage to the caliper 40. Secondly, the floating distance of the floating component 20 is easy to control, preventing the guide rod 12 from swaying too much or too little and thus failing to perform its guiding function. Therefore, once the floating component 20 is set to the predetermined floating distance of the guide rod 12, it will not cause the caliper 40 to fail to guide or be damaged due to human error. In addition, the overall structure composed of the floating component 20 and the guide component 10 has low complexity, is efficient and convenient to assemble, and is easy to promote and apply widely.

[0052] like Figure 5 As shown, the floating assembly 20 provided in this application includes a housing 21 and a floating shaft 22. Along the axial direction of the guide rod 12 (e.g., Figure 1 (In the direction indicated by the middle arrow X), the end of the housing 21 near the drive component 11 is connected to the drive component 11, and a mounting cavity 210 is provided inside the housing 21. Along the radial direction of the guide rod 12, the floating shaft 22 is at least partially connected to the mounting cavity 210 and has a mounting gap between it and the inner wall surface of the mounting cavity 210, so that the floating shaft 22 can float relative to the housing 21 along the radial direction of the guide rod 12, thereby driving the guide rod 12 to float. The end of the floating shaft 22 away from the housing 21 is located outside the mounting cavity 210 and is connected to the guide rod 12.

[0053] In other words, in this embodiment, after connecting the outer shell 21 of the floating component 20 to the driving component 11, the floating shaft 22 of the floating component 20, located outside the outer shell 21, is connected to the guide rod 12, making assembly efficient and convenient. The outer shell 21 and the driving component 11 can be detachably connected together using fasteners (such as bolts, screws, etc.) to facilitate maintenance and replacement of the floating component 20 and / or the driving component 11. The outer shell 21 and the driving component 11 can also be welded together.

[0054] like Figure 5As shown, the floating assembly 20 in this embodiment also includes a rolling element 23. The rolling element 23 is mounted between the floating shaft 22 and the inner wall of the mounting cavity 210 via the mounting structure 30. Under the drive of the floating shaft 22, the rolling element 23 can roll relative to the floating shaft 22 and the inner wall of the mounting cavity 210. Thus, during the floating process of the floating shaft 22 driving the guide rod 12 to float, the rolling element 23 can reduce the contact area between the floating shaft 22 and the inner wall of the mounting cavity 210, thereby reducing the friction between the floating shaft 22 and the inner wall of the mounting cavity 210.

[0055] Secondly, the rolling element 23 can also reduce the friction between the floating shaft 22 and the inner wall of the mounting cavity 210, converting the sliding friction between the floating shaft 22 and the inner wall of the mounting cavity 210 into rolling friction, reducing the resistance encountered by the floating shaft 22 during floating, and making the movement of the floating shaft 22 driving the guide rod 12 more smooth. Moreover, the way the floating shaft 22 makes rolling contact with the inner wall of the mounting cavity 210 through the rolling element 23 allows the floating shaft 22 to float or rotate more flexibly within the mounting cavity 210, adapting to the small displacements of the guide rod 12 in different directions, thereby improving the coaxial accuracy between the components of the caliper 40 when the guide rod 12 drives the caliper 40. In addition, since this rolling contact method produces less wear, it can also extend the service life of the floating assembly 20.

[0056] The rolling element 23 in this application may specifically include steel balls. Of course, depending on the load capacity and cost requirements of the floating component 20 in the actual application scenario, the rolling element 23 may also include at least one of ceramic balls, plastic balls, glass balls, copper balls, etc., and this application does not impose a unique limitation on this.

[0057] like Figure 5 As shown, the outer peripheral wall of the floating shaft 22 is provided with a first outer flange 221, which is located inside the mounting cavity 210. Along the axial direction of the guide rod 12, the inner wall surface of the mounting cavity 210 includes a top surface 101 near the drive component 11 and a bottom surface 102 near the guide rod 12.

[0058] The mounting structure 30 includes a first mounting groove 301, which is disposed on at least one of the first outer flange 221 and the bottom surface 102. The rolling element 23 is rotatably mounted within the first mounting groove 301. When the first mounting groove 301 is disposed on the first outer flange 221, it is located on the side of the first outer flange 221 closest to the top surface 101. This ensures that when the rolling element 23 is rotatably mounted within the first mounting groove 301 on the first outer flange 221, it is less likely to roll off under gravity, thus ensuring the stability of the rolling element 23. Furthermore, the structure of the first mounting groove 301 is convenient to create, facilitating the installation of the rolling element 23.

[0059] The first mounting groove 301 extends circumferentially along the guide rod 12. Therefore, the first mounting groove 301 can be an open arc-shaped groove structure or a closed circular groove structure. Multiple rolling elements 23 are spaced apart within the first mounting groove 301 along the circumferential direction of the guide rod 12, thereby reducing friction between the floating shaft 22 and the mounting cavity 210 and allowing for more flexible floating.

[0060] The mounting structure 30 also includes a first mounting block 31 and a second mounting block 32. Along the radial direction of the guide rod 12, the first mounting block 31 and the second mounting block 32 are spaced apart to form a first mounting groove 301. Thus, by spaced-apart mounting the first mounting block 31 and the second mounting block 32 on the first outer flange 221 and / or the bottom surface 102 of the floating shaft 22, the first mounting groove 301 can be obtained, facilitating assembly. Although the first mounting groove 301 can also be obtained by directly carving a groove in the first outer flange 221 or the bottom surface 102, obtaining the first mounting groove 301 by spaced-apart mounting blocks 31 and 32 improves the structural strength of the floating shaft 22 and the outer casing 21.

[0061] The first mounting groove 301 includes at least two, with at least one first mounting groove 301 disposed on the first outer flange 221. The mounting structure 30 also includes a pad 33, which is disposed on the bottom surface 102 and opposite to the first outer flange 221. Along the axial direction of the guide rod 12, at least another first mounting groove 301 is disposed on the side of the pad 33 near the first outer flange 221. The first mounting groove 301 can be directly carved into the pad 33 for the installation of the rolling element 23, or the first mounting block 31 and the second mounting block 32 can be installed on the pad 33 to obtain the first mounting groove 301. Regardless of the form, the pad 33 can avoid directly opening the first mounting groove 301 inside the outer shell 21, ensuring the structural strength of the outer shell 21 while making the installation of the first mounting groove 301 more convenient and efficient, thereby improving the assembly efficiency and overall structural strength of the floating component 20.

[0062] Optionally, along the radial direction of the guide rod 12, the floating shaft 22 has a first position relative to the housing 21, offset from the central axis of the mounting cavity 210, and a second position coaxial with the mounting cavity 210. The floating assembly 20 also includes a reset component 24 disposed between the floating shaft 22 and the inner wall surface of the mounting cavity 210. The reset component 24 can drive the floating shaft 22 to reciprocate between the first and second positions. Thus, after the guide rod 12 completes the alignment operation of the caliper 40 and separates from the caliper 40, the reset component 24 can reset the guide rod 12 to the second position, preparing for the assembly of the next caliper 40.

[0063] When the floating shaft 22 includes a first outer flange 221, the reset component 24 in this embodiment may include at least three elastic elements 241 and at least three second mounting slots 242. Along the radial direction of the guide rod 12, at least three second mounting slots 242 are disposed on the side of the first outer flange 221, and are spaced apart circumferentially along the guide rod 12. At least three elastic elements 241 are correspondingly installed within the at least three second mounting slots 242. Furthermore, along the radial direction of the guide rod 12, one end of each elastic element 241 away from the bottom of the second mounting slot 242 is fixedly connected to the inner wall of the mounting cavity 210. Thus, based on the elastic force of the at least three elastic elements 241, the floating shaft 22's floating motion is not affected. When the floating shaft 22 needs to be reset, it can also be stably pulled back to a position coaxial with the outer casing 21 when the external force (transmitted to the floating shaft 22 by the guide rod 12) on the floating shaft 22 is removed. The elastic element 241 in this application may include a compression spring. The second mounting groove 242 can improve the stability of the elastic element 241 during movement.

[0064] Of course, in some embodiments, the second mounting groove 242 can also be disposed on the inner wall surface of the mounting cavity 210 relative to the first outer flange 221. When disposed on the first outer flange 221, it is easier to process. Moreover, in this embodiment, the reset component 24 is installed between the first outer flange 221 of the floating shaft 22 and the inner wall surface of the mounting cavity 210, which provides sufficient installation space for the installation of the rolling element 23 and improves the space utilization of the mounting cavity 210.

[0065] like Figure 5 and Figure 6 As shown, the outer peripheral wall of the floating shaft 22 is also provided with a second outer flange 222. The second outer flange 222 and the first outer flange 221 are spaced apart along the axial direction of the guide rod 12 and are located at one end of the floating shaft 22 near the guide rod 12. The guide assembly 10 also includes a connecting seat 13, which is installed between the second outer flange 222 and the guide rod 12.

[0066] In this embodiment, the connection between the connecting seat 13 and the second outer flange 222 on the floating shaft 22 is not only convenient but also improves the connection strength between the guide rod 12 and the floating shaft 22, making the connection between the guide rod 12 and the floating shaft 22 more stable and reliable. In some embodiments, the connecting seat 13 and the second outer flange 222 can be detachably fixed together using fasteners (such as bolts and screws), which not only ensures a firm connection but also facilitates the disassembly and maintenance of the floating assembly 20.

[0067] like Figure 6As shown, along the axial direction of the guide rod 12, the connecting seat 13 has a connecting groove 131 on the side near the floating shaft 22. The shape of the second outer flange 222 is adapted to the inner wall surface of the connecting groove 131, and the second outer flange 222 is embedded in the connecting groove 131 and fixedly connected to the connecting groove 131. Thus, by embedding the second outer flange 222 on the floating shaft 22 into the connecting groove 131 to connect with the connecting seat 13, the contact area between the floating shaft 22 and the connecting seat 13 is larger, the connection strength is stronger, and the connection strength and stability between the floating shaft 22 and the guide rod 12 are further improved.

[0068] In this embodiment, the driving component 11 includes a driving element and a pushing element, such as... Figure 1 As shown, the pusher includes a sleeve 111 and a connecting shaft 112. One end of the connecting shaft 112 is fitted inside the sleeve 111 and can move axially relative to the sleeve 111. The other end of the connecting shaft 112 is connected to the housing 21. Along the axial direction of the connecting shaft 112, the drive member is connected to the end of the sleeve 111 away from the housing 21 to drive the pusher to move the guide rod 12 in a linear motion. Before pressing the caliper 40, the drive member can drive the pusher to move as a whole toward the caliper body 43 of the caliper 40, thereby enabling the guide rod 12 to pass into the caliper body 43 and engage with the screw on the piston 41. During the pressing process where the piston 41 is pressed into the clamp body 43 of the caliper 40 by the press-fitting equipment, when the guide rod 12 is subjected to the reverse force from the piston 41, it can move away from the piston 41 under the drive of the connecting shaft 112. This ensures that the guide rod 12 can make linear motion to guide the pressing motion of the piston 41 and its transmission connecting assembly 42. At the same time, the guide rod 12 can move away from the piston 41 (actually upward) to avoid the guide rod 12 being damaged by strong impact, thereby improving the safety and reliability of the guiding mechanism during operation.

[0069] The pusher may also include a spring 113, which is disposed between the end of the connecting shaft 112 away from the guide rod 12 and the inner wall surface of the sleeve 111. When the force acting on the guide rod 12 toward the sleeve 111 is removed, the spring 113 can push the guide rod 12 back to its initial position so that the guide rod 12 can better perform the guiding operation.

[0070] The driving component may specifically include a cylinder. The extension rod of the cylinder can be connected to the sleeve 111 via a fixing block 114, so that when the extension rod of the cylinder extends, it can drive the driving component 11 as a whole to move the guide rod 12 into the clamp body 43 and engage with the transmission connection kit 42. Secondly, the fixing block 114 can also improve the connection strength between the cylinder and the sleeve 111.

[0071] As can be seen from the above, when the guiding mechanism provided in this application is used in conjunction with the pressing equipment to assemble the piston 41 of the caliper 40, it can avoid damage to the caliper 40 product caused by internal forces due to misalignment of the piston 41, transmission connection kit 42 and guide rod 12, etc. It can adaptively eliminate misalignment (i.e., deviation in coaxiality between the piston 41 and its transmission connection kit 42 and the caliper body 43), reduce the defect rate of the caliper 40 product, and thus improve the production efficiency of the caliper 40.

[0072] The second embodiment of this application also provides a pressing device, which includes a guiding mechanism. The specific structure of the guiding mechanism is described in the first embodiment of this application, and therefore will not be repeated here.
