Description

Technical Field

[0001] This invention relates to the field of brake technology, and more specifically, to a brake assembly method and system. Background Technology

[0002] In various mechanical braking systems, especially brakes, torque transmission between the motor and piston is typically achieved through a spline connection, where the external spline of the motor meshes with the internal spline of the piston to transmit torque. Traditional assembly processes usually include conveying, alignment, and pressing steps. Current technology commonly uses mechanical guides, vibratory feeders, or simple vision sensors for orientation, followed by a linear actuator directly pressing the external spline of the motor into the internal spline of the piston. However, this traditional method has significant limitations. During the assembly of the motor and piston in many brakes, the circumferential rotation of the motor relative to the piston is restricted. Excessive rotation can damage parts, and the initial angular positions of the motor and piston are relatively random, often resulting in alignment deviations. This leads to assembly failure, causing damage to parts, low product yield, and failing to meet the requirements of automated production lines for assembly success rate and stability.

[0003] Therefore, there is an urgent need for an assembly technology that can achieve high-precision circumferential angle pre-alignment before assembling external and internal splines under physical space constraints. Summary of the Invention

[0048] Brakes, commonly used in automobiles, are components that generate a force (braking force) that resists the movement or tendency of a vehicle to move. A brake typically consists of a motor and a piston, with the external splines of the motor meshing with the internal splines of the piston to transmit torque. Current technology commonly uses mechanical guides, vibratory discs, or simple visual sensors for initial orientation, followed by a linear actuator directly pressing the external splines of the motor into the internal splines of the piston. However, during assembly, the relative circumferential rotation range of the motor and piston is limited, and misalignment between the motor and piston often occurs, leading to assembly failure.

[0049] Therefore, the present invention provides a brake assembly method and system that can solve the problem of assembly failure caused by misalignment between the piston and motor of the brake under assembly conditions with limited physical space.

[0050] Example 1:

[0051] Please refer to Figure 1 , Figure 2 and Figure 3 This embodiment provides a brake assembly method, including the following steps S10-S50:

[0052] S10, based on the brake assembly command trigger, obtain the first angle parameter of the drive assembly 20 and the second angle parameter of the piston assembly 10;

[0053] Understandably, triggered by the brake assembly command, the conveying assembly 30 moves the piston assembly 10 directly below the adjusting assembly 40. The adjusting assembly 40 engages with the second internal spline 154 of the piston assembly 10 along the third direction Z. The adjusting assembly 40 acquires the second angle parameter and uploads it to the control system for subsequent assembly analysis; the specifics depend on the actual application. Simultaneously, the acquisition assembly 50 acquires the first angle parameter of the second external spline 242 of the drive assembly 20 and uploads it to the control system; the specifics depend on the actual application.

[0054] For details, please refer to Figure 4 and Figure 5 The drive assembly 20 includes an output shaft and a second external spline 242 located at one end of the output shaft. The second external spline 242 has a plurality of spline teeth circumferentially arranged along the central axis of the second external spline 242. The piston assembly 10 includes a lead screw unit 15 and a second internal spline 154 located at one end of the lead screw unit 15. The second internal spline 154 has a plurality of spline grooves circumferentially arranged along the central axis of the second internal spline 154. The spline teeth and spline grooves mesh with each other, that is, the second external spline 242 of the drive assembly 20 and the second internal spline 154 of the piston assembly 10 rotate and mesh to realize torque transmission.

[0055] Specifically, the first angle parameters in step S10 include: the number of teeth, module, pressure angle of the second external spline 242, and the first angle α between the symmetrical center line of any spline shaft tooth and the first direction X, wherein the first direction X is the moving direction of the conveying assembly 30.

[0056] Specifically, the second angle parameters in step S10 include: the number of teeth, module, pressure angle of the second internal spline 154, and the second and third angles β1 and β2 between the symmetrical center lines of the two adjacent spline grooves and the first direction X, respectively.

[0057] S20, based on the first angle parameter and the second angle parameter, obtain the preset adjustment rule.

[0058] Specifically, the preset adjustment rules include: when the number of teeth, module, and pressure angle of the second external spline 242 and the second internal spline 154 are the same and the first included angle α and the second included angle β1 are different; the piston assembly 10 is adjusted to the target angle based on the first comparison rule, the second comparison rule and the third comparison rule, where the target angle is the same as the second included angle β1 and the first included angle α.

[0059] Understandably, ensuring that the number of teeth, module, and pressure angle of the second internal spline 154 and the second external spline 242 are the same is a prerequisite for adjusting to the target angle before pre-alignment. Only when the number of teeth, module, and pressure angle are the same can the first included angle α and the second included angle β1 be further compared. When the first included angle α and the second included angle β1 are the same, it means that the second internal spline 154 of the piston assembly 10 is already at the target angle, and no further adjustment by the adjustment component 40 is required. When the first included angle α and the second included angle β1 are different, the adjustment component 40 will further adjust the piston assembly 10 to the target angle based on the first comparison rule, the second comparison rule, and the third comparison rule.

[0060] Understandably, the first comparison rule is: when the second included angle β1 is greater than or equal to the third included angle β2, the piston assembly 10 rotates and moves along the second direction Y. The second comparison rule is: when the second included angle β1 is less than the third included angle β2 and greater than the reference angle, the piston assembly 10 rotates and moves along the second direction Y. The third comparison rule is: when the second included angle β1 is less than the third included angle β2 and the reference angle, the piston assembly 10 rotates and moves along the third direction Z. The specific value depends on the actual application. The reference angle is the critical value at which the transmission unit 16 and the lead screw unit 15 abut against each other; the specific value depends on the actual application, and the specific value of the reference angle is not limited in this invention.

[0061] S30, the adjustment component 40 adjusts the piston assembly 10 to the target angle based on the preset adjustment rules.

[0062] Further, please refer to Figure 2 and Figure 5 Before the piston assembly 10 is adjusted to the target angle by the adjustment component 40 based on the preset adjustment rules, the piston assembly 10 is in its initial state. This initial state includes: the end of the transmission unit 16 near the drive component 20 abuts against the lead screw unit 15 along the second direction Y, making it difficult for any internal component of the piston assembly 10 to shake during movement, thereby ensuring the angular accuracy of the subsequent assembly of the second internal spline 154. The piston assembly 10 also includes the transmission unit 16, which is sleeved on the lead screw unit 15, converting the rotation of the lead screw unit 15 into sliding of the transmission unit 16 along the second direction Y or the third direction Z on the lead screw unit 15.

[0063] Understandably, the tight contact between the transmission unit 16 and the lead screw unit 15 ensures that the lead screw unit 15 does not easily rotate as the conveying assembly 30 moves, thus preventing the second internal spline 154 from shifting angle. That is, during the process of adjusting the piston assembly 10 to the target angle using the adjusting assembly 40, the direction of rotation of the second internal spline 154 or the lead screw unit 15 ensures that the transmission unit 16 can be tightly contacted with the lead screw unit 15 along the second direction Y. If the direction of rotation of the second internal spline 154 causes the transmission unit 16 to move along the third direction Z, there will be a gap between the transmission unit 16 and the lead screw unit 15, which may lead to inaccurate target angle of the second internal spline 154, resulting in assembly failure.

[0064] Furthermore, based on the first comparison rule, when the second included angle β1 is greater than or equal to the third included angle β2, the adjustment component 40 drives the piston component 10 to adjust to the target angle along the second direction Y.

[0065] Furthermore, based on the second comparison rule, when the second included angle β1 is less than the third included angle β2 and greater than the reference angle, the adjustment component 40 drives the piston assembly 10 to adjust to the target angle along the second direction Y.

[0066] Understandably, the reference angle is the critical value at which the transmission unit 16 and the lead screw unit 15 are pressed together. For example, the reference angle is 30°, the second included angle β1 is 40°, and the third included angle β2 is 50°. The adjustment component 40 drives the piston assembly 10 to adjust to the target angle along the second direction Y. The specific value depends on the actual application. In this invention, the specific value of the reference angle is not limited.

[0067] Furthermore, based on the third comparison rule, when the second included angle β1 is less than the third included angle β2 and the reference angle, the adjusting component 40 rotates the piston assembly 10 to adjust it to the target angle along the third direction Z; wherein, the third direction Z is perpendicular to the first direction X and opposite to the second direction Y.

[0068] Understandably, the reference angle is the critical value at which the transmission unit 16 and the lead screw unit 15 abut together. For example, the reference angle is 40°, the second included angle β1 is 30°, and the third included angle β2 is 45°. The adjustment component 40 drives the piston assembly 10 to adjust to the target angle along the third direction Z. The specific value depends on the actual application. In this invention, the specific value of the reference angle is not limited.

[0069] Furthermore, the adjustment component 40 adjusts the piston assembly 10 based on preset adjustment rules and then stays for a preset duration.

[0070] Understandably, the piston assembly 10 is equipped with a first sealing ring 12 and a second sealing ring 13, and the adjustment assembly 40 stays for a preset time to ensure the stability of the target angle.

[0071] For example, after adjusting the piston assembly 10 based on the preset adjustment rules, the adjustment component 40 can also adjust the second internal spline 154 by a little more angle to ensure that the target angle of the first internal spline 142 is still the angle that can be assembled with the drive assembly after the first sealing ring 12 and the second sealing ring 13 rebound.

[0072] S40, the conveying assembly 30 moves the piston assembly 10, which has been adjusted to the target angle, to the target assembly position; wherein the target assembly position includes the drive assembly 20 being within the installation margin range of the piston assembly 10.

[0073] Further, please refer to Figure 5 The piston assembly 10 also includes two mounting arms 17, which are symmetrically sleeved on one end of the lead screw unit 15 near the second internal spline 154 along the second direction Y. The range of rotation of any mounting arm 17 along the central axis of the lead screw unit 15 by 180° is the installation allowance range.

[0074] That's understandable, please refer to it. Figure 6 and Figure 7 The drive assembly 20 includes a motor, which is usually located on the right side of the drive assembly 20. During the installation of the piston assembly 10 and the drive assembly 20, the motor is prone to colliding with the mounting arm 17, which may cause damage to the parts and thus assembly failure. Therefore, it is necessary to ensure that the drive assembly 20 is within the installation margin range of the piston assembly 10 so that the drive assembly 20 can rotate and lock within the installation margin range.

[0075] S50, the pressing assembly 60 presses the drive assembly 20 onto the piston assembly 10.

[0076] Furthermore, the pressing assembly 60 drives the second external spline 242 to press into the second internal spline 154 along the third direction Z; the pressing assembly 60 drives the second external spline 242 to rotate within the installation allowance range and drives the second external spline 242 to lock with the second internal spline 154.

[0077] Example 2:

[0078] This embodiment provides a brake assembly system based on the above-described brake assembly method, the brake assembly system comprising:

[0079] Bracket 70;

[0080] The acquisition component 50 is mounted on the bracket 70. The acquisition component 50 includes an acquisition base and an acquisition device. The acquisition base is located on the side of the bracket 70 near the pressing component 60, and the acquisition device is located on the acquisition base for acquiring the first angle parameter of the driving component 20.

[0081] An adjustment assembly 40 is mounted on a bracket 70. The adjustment assembly 40 includes a drive unit 4122, a vertical displacement unit 42, and a drive head 43. The drive unit 4122 is drivably connected to the vertical displacement unit 42 and the drive head 43. The vertical displacement unit 42 and the drive head 43 are connected. The drive head 43 is used to adjust the angle of the piston assembly 10. The vertical displacement unit 42 drives the drive head 43 to move along the third direction Z.

[0082] The conveying assembly 30 includes a conveyor belt 31 and a movable tray 32. The conveyor belt 31 is mounted on a support 70. The conveyor belt 31 is slidably connected to the movable tray 32. The conveyor belt 31 drives the movable tray 32 to slide along a first direction X to the target assembly position. The piston assembly 10 is movably connected to the movable tray 32. Furthermore, the movable tray 32 can move along a second direction Y or a third direction Z on the conveyor belt 31, which can drive the piston assembly 10 to quickly assemble with the adjusting assembly 40 or the pressing assembly 60, thereby improving assembly efficiency.

[0083] A pressing assembly 60 is mounted on a bracket 70. The pressing assembly 60 includes a translational portion 61, a vertical portion 62, a rotating portion 63, and a clamping portion 64. The translational portion 61 is mounted on the bracket 70. The vertical portion 62 is movably connected to the translational portion 61. The vertical portion 62 is movably connected to the rotating portion 63. The clamping portion 64 is movably connected to the rotating portion 63. There is an installation allowance between the bracket 70, the pressing assembly 60, and the piston assembly 10. The drive assembly 20 is located within this installation allowance to prevent collisions between the drive assembly 20 and any of the bracket 70, the pressing assembly 60, or the piston assembly 10 during assembly, which could lead to component failure. Furthermore, the adjustment assembly 40 and the pressing assembly 60 are sequentially mounted on the bracket 70 along the first direction X. The piston assembly 10 is first aligned according to the order of the adjustment assembly 40 and the pressing assembly 60, and then the drive assembly 20 is assembled with the piston assembly 10 based on the pressing assembly 60.

[0084] Further, please refer to Figures 5-7 The piston assembly 10 includes a piston cylinder 11 and a first sealing ring 12, a second sealing ring 13, a piston unit 14, a lead screw unit 15 and a transmission unit 16 disposed within the piston cylinder 11.

[0085] The piston unit 14 includes a piston cylinder 141 and a first internal spline 142 arranged circumferentially along the piston cylinder 141; the lead screw unit 15 includes an integrally formed lead screw body 151, a rod engagement portion 152, an extension rod 153, and a second internal spline 154; the extension rod 153 is perpendicularly connected to the rod engagement portion 152 and protrudes from the piston cylinder 11 in the second direction Y; the end of the extension rod 153 away from the rod engagement portion 152 is provided with the second internal spline 154; wherein, the first sealing ring 12 is located on the rod engagement portion 152 and sleeved on the circumferential direction of the extension rod 153 to seal the piston cylinder 11; the lead screw body 151 is perpendicularly connected to the rod engagement portion 152 and extends into the piston cylinder 141 in the third direction Z; the transmission unit 16 is sleeved on the lead screw body 151.

[0086] The transmission unit 16 includes an integrally formed first external spline 161, a transmission ring 162, an inner thread portion 163, and a ring engaging portion 164; the transmission ring 162 has an inner thread portion 163 inside; the transmission ring 162 is connected to the lead screw body 151 through the inner thread portion 163, and the transmission ring 162 moves on the lead screw body 151 along the second direction Y or the third direction Z; the first external spline 161 is connected to the transmission ring 162 along the third direction Z and is connected to the first internal spline 142; the ring engaging portion 164 is located at the end of the transmission ring 162 away from the first internal spline 142 along the second direction Y, and the ring engaging portion 164 slides on the lead screw body 151 along the second direction Y or the third direction Z; the second sealing ring 13 is sleeved on the piston cylinder body 11 circumferentially along the third direction Z.

[0087] Understandably, both the first sealing ring 12 and the second sealing ring 13 are used to seal the piston assembly 10. Since the first sealing ring 12 and the second sealing ring 13 have resilience, the adjustment component 40 adjusts the piston assembly 10 based on the preset adjustment rules and stays for a preset time to ensure the accuracy of the target angle.

[0088] Furthermore, the drive assembly 20 includes a drive housing 21 and a drive section 4122 and a reduction section 23 disposed within the drive housing 21.
