Description

Technical Field

[0001] This utility model specifically relates to a brake subassembly press-fitting machine. Background Technology

[0002] In a parking brake, the brake subassembly is crucial. When the driver brings the vehicle to a stop and engages the handbrake, the brake subassembly comes into play, pushing the piston to ensure a tight fit between the brake pads and the brake disc, guaranteeing a stable parking position. Its core components include spring seat sleeves, springs, and ball bearing sleeves; the precise coordination of these parts is key to ensuring effective braking.

[0003] Chinese utility model patent CN205025976U discloses the structure of a brake caliper assembly, and the brake sub-assembly mentioned in this application is a part of it, installed on the parking caliper body. One end is connected to a rotating bracket via a ball bearing screw, and the other end is connected to an adjusting sleeve via a threaded guide rod. During operation, rotating the bracket drives the ball bearing screw, which in turn drives the brake pads through a precision transmission to achieve braking. The structure and installation position of the brake sub-assembly can be clearly seen in Figure 1 of the patent specification.

[0004] However, in the production process of brake subassemblies, after the individual components are machined, they need to undergo an assembly process to form a complete assembly. This involves key steps such as press-fitting the threaded guide rod, assembling the ball bearing screw, and pressing and riveting the edges. Existing assembly machines have limitations in this regard, and it is usually difficult to complete all processes on a single machine. This results in the need to use multiple machines and transfer products multiple times, making it impossible to achieve one-machine molding and increasing the complexity and cost of production.

[0005] Secondly, when the threaded guide rod is press-fitted first, it tends to move upward due to the action of the spring. At this time, relying solely on the existing press-fitting device, without any limiting components below to limit the threaded guide rod, the threaded guide rod pops upward after the cylinder exits. At this time, it is impossible to clamp the steel ball sleeve screw. Therefore, the existing press-fitting device cannot be directly applied to assembling the brake sub-assembly.

[0006] In summary, in view of the shortcomings of the prior art, this application proposes a brake sub-assembly assembly machine, which aims to solve the problem of multi-process press assembly on a single machine. It can be directly applied to the assembly of brake sub-assemblies, thereby improving production efficiency, reducing production costs, and ensuring product quality and performance. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a brake sub-assembly press machine to address the shortcomings of the prior art. This machine can realize multi-process assembly of brake sub-assemblies without the need for multiple machines or multiple product runs, which facilitates the assembly of brake sub-assemblies, improves production efficiency, and ensures that the steel ball sleeve screw does not wobble left and right or move up and down during the entire assembly process, and the threaded guide rod does not move up and down.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a brake subassembly press-fitting machine, comprising a frame, a fixture mounted on the frame for clamping products, a press head device distributed above the fixture, a clamping device distributed below the fixture for fixing products, and a riveting device surrounding the outer periphery of the fixture, characterized in that: the press head device includes a press turntable, a press turntable drive mechanism for driving the press turntable to rotate, and a first cylinder distributed above the press turntable and fixed on the frame; the press turntable is linked to several sets of press rod mechanisms arranged sequentially and at intervals along the circumference of the press turntable; the frame is provided with a first through hole corresponding to the output end of the first cylinder; when the press turntable rotates to a position where a set of press rod mechanisms corresponds to the first through hole, the output end of the first cylinder can pass through the first through hole and drive a set of press rod mechanisms to reciprocate toward the fixture.

[0009] By adopting the above technical solution, the assembly of the brake subassembly can be carried out in multiple processes without the need to set up multiple machines or run the product multiple times, which facilitates the assembly of the brake subassembly and improves production efficiency. The specific operation is as follows: Using a manual or robotic arm, place the spring seat on the fixture, place the threaded guide rod on one set of pressure rod mechanisms, and place the ball bearing screw on another set of pressure rod mechanisms. The pressure rod mechanism with the threaded guide rod moves downward to complete the press-fitting of the threaded guide rod. Then, the clamping device limits the threaded guide rod, so that even if this set of pressure rod mechanisms rises, the threaded guide rod will not spring upward under the action of the spring. The pressure turntable drive mechanism drives the pressure turntable to rotate until the pressure rod mechanism with the ball bearing screw aligns with the position of the first through hole. Then, the pressure rod mechanism with the ball bearing screw moves downward. After the ball bearing screw reaches the predetermined position, this set of pressure rod mechanisms does not rise temporarily. Immediately afterwards, the riveting device works to rivet the outer edge of the spring seat, connecting the ball bearing screw to the spring seat. Then, this set of pressure rod mechanisms rises. The actual operation clearly demonstrates that this technical solution eliminates the need for multiple product runs, enabling multi-stage press-fitting of the brake subassembly. It avoids the need for multiple machines and repeated product runs, facilitating brake subassembly assembly and improving production efficiency. Furthermore, throughout the assembly process, the ball bearing screw will not wobble left or right, nor will it move up or down, and the threaded guide rod will also remain stationary.

[0010] The aforementioned brake subassembly press machine can be further configured such that: the frame is also provided with a positioning component for positioning the press turntable, the positioning component includes a positioning rod and a second cylinder linked to the positioning rod, a set of positioning holes on the press turntable is distributed between each two adjacent sets of press rod mechanisms, a set of positioning sleeves is installed at the positioning holes, and the end of the positioning rod away from the second cylinder is tapered.

[0011] Using the above technical solution, during the pressing process, the positioning assembly, through the cooperation of the positioning rod and the positioning sleeve, can stably maintain the pressing turntable in its working state, preventing the pressing turntable from rotating or shifting, and ensuring that each set of pressing rod mechanisms can accurately align with the first through hole, thereby achieving precise pressing action. When it is necessary to change the pressing rod mechanism, the second cylinder controls the positioning rod to retract from the positioning sleeve, and the pressing turntable can then rotate. The end of the positioning rod is tapered, facilitating the insertion of the positioning rod into the positioning sleeve. By setting a positioning sleeve to replace the positioning hole in cooperating with the positioning rod, excessive wear of the pressing turntable is avoided, extending its service life.

[0012] The aforementioned brake subassembly press machine can be further configured as follows: the pressing turntable drive mechanism includes a belt and a driving pulley and a driven pulley linked to both ends of the belt. The driven pulley is fixed below the pressing turntable, and each driven pulley is provided with a set of clearance holes corresponding to each group of pressing rod mechanisms. The driving pulley is linked to a first servo motor. The pressing turntable drive mechanism also includes an adjusting frame and an adjusting bolt. The body of the first servo motor is fixed on the adjusting frame. The adjusting frame is provided with several sets of parallel first strip holes. Fasteners are connected to the first strip holes. The fasteners are detachably connected to the frame. The side of the adjusting frame is provided with a T-slot. The head of the adjusting bolt is engaged in the T-slot. The shank of the adjusting bolt is threadedly connected to a connecting block. The connecting block is fixed on the frame and is provided with a connecting hole threadedly connected to the adjusting bolt.

[0013] Using the above technical solution, the first servo motor drives the pressure turntable to rotate via the active pulley, belt, and driven pulley, thereby changing the pressure lever mechanism. The structural features such as the adjusting frame, adjusting bolt, T-slot, and first slot allow for adjustment of the positions of the first servo motor and driven pulley, adapting to changes in belt tension and eliminating the effects of machining errors. When adjusting the installation position of the pressure turntable drive mechanism, first loosen the fastener at the first slot (this fastener can be a standard part such as a screw). Due to the structure of the T-slot, the adjusting frame can be directly removed. Then, rotate the adjusting bolt according to actual needs to change the extension length of the adjusting bolt relative to the connecting block until the required length is reached. Next, engage the T-slot of the adjusting frame with the head of the adjusting bolt, and finally use the fastener and the first slot to fix the adjusting component onto the frame.

[0014] The aforementioned brake subassembly press machine can be further configured as follows: the press rod mechanism includes a guide sleeve that is hollow inside and open at both ends; the press platen is provided with several sets of second through holes; the upper end of each set of guide sleeves is installed in a set of second through holes; a press rod is slidably connected inside the guide sleeve; the press rod is linked to a reset component; and the lower end of the press rod is linked to a clamping component capable of clamping the processed product; the reset component includes a spring sleeved on the outer periphery of the press rod; an upper flange is fixed at the upper end of the press rod; the upper flange is clearance-fitted with the guide sleeve; a lower flange is fixed inside the guide sleeve and is disposed opposite to the upper flange; one end of the spring is in contact with the upper flange and the other end is in contact with the lower flange.

[0015] By employing the above technical solution, the precise positioning of the pressure rod is achieved through the cooperation of the guide sleeve and the second through hole on the pressure platen, ensuring accuracy during the pressing process. Since the pressure platen can rotate until different guide sleeves correspond to the first through hole, different pressure rod mechanisms can be quickly switched, improving work efficiency. Because the clamping parts can be replaced according to different processed products, this pressing device can adapt to processed products of different shapes and sizes, increasing the device's pressing applicability. A spring ensures that the pressure rod automatically resets after pressing. The hollow guide sleeve design makes the device compact, space-saving, and easy to integrate into existing production lines. The specific operation is as follows: The pressure platen rotates under the drive of the pressure platen drive mechanism. Different guide sleeves will correspond to the second through hole. Only one set of guide sleeves corresponds to the first through hole at a time. The output end of the first cylinder passes through the first through hole and pushes the pressure rod down. The lower part of the pressure rod is equipped with clamping parts for clamping the processed product. After pressing is completed, the first cylinder resets, and the pressure rod automatically resets under the action of the spring.

[0016] The aforementioned brake sub-assembly press machine can be further configured as follows: the riveting device includes a rotatable rotating ring, ring plates distributed below the rotating ring, a limiting ring sleeved on the outer circumference of the rotating ring, and a rotary drive mechanism linked with the rotating ring. The limiting ring is fixed on the frame, the ring plates are fixedly connected to the rotating ring, a third through hole is penetrating the middle of the rotating ring, the clamp is distributed in the middle of the third through hole, several sets of riveting blocks are arranged between the rotating ring and the clamp, the several sets of riveting blocks are arranged sequentially at intervals along the circumference of the clamp, the end of the riveting block away from the clamp is linked with a guide post, the frame is provided with a set of strip-shaped guide holes that are clearance-fitted with the guide posts for each set of guide posts, the guide posts are arranged radially along the rotating ring, and the ring plates are provided with a set of inclined sliding grooves for each set of guide posts.

[0017] Using the above technical solution, the rotary drive mechanism drives the rotating ring to rotate. Since the rotating ring is fixedly connected to the ring plate, the ring plate rotates together with the rotating ring. The limiting ring constrains and guides the rotational movement of the rotating ring. During the rotation of the rotating ring, the limiting ring can prevent axial or radial displacement of the rotating ring, ensuring more stable rotational movement. The ring plate is provided with a slanted groove. When the ring plate rotates, the inclined structure of the slanted groove pushes the guide post to move along the strip guide hole and move closer to the fixture, thereby pushing the rivet block to perform riveting work. It can be seen that this solution ensures that multiple sets of rivet blocks can be driven synchronously, solving the problem that it is difficult to achieve synchronous driving of multiple sets of rivet blocks and driving components, and reducing the cost of the riveting device. The main function of the third through hole is to make way, facilitating the installation of the rivet block and guide post, and providing a certain working space for their movement. The ring plate is set below the rotating ring, providing an installation surface for the slanted groove.

[0018] The aforementioned brake subassembly press machine can be further configured as follows: the rotary drive mechanism includes a third cylinder, a push rod hinged to the output end of the third cylinder, and a positioning block. The body of the third cylinder is hinged to a hinge block, which is fixed on a mounting base. The mounting base is distributed on the side of the rotating ring and fixed to the frame. The rotating ring is provided with several sets of screw holes arranged sequentially and at intervals along the circumference of the rotating ring. The positioning block is connected to at least one set of screw holes by screws, and the positioning block is linked with the push rod.

[0019] Using the above technical solution, when the piston rod of the third cylinder extends or retracts, the push rod not only moves back and forth relative to the body of the third cylinder, but also swings along with the entire third cylinder, ultimately converting this into the rotation of the rotating ring, causing the inclined slide groove to rotate accordingly. The inclined structure of the slide groove converts the rotational motion of the rotating ring into a thrust on the guide post, causing the guide post to move within the strip-shaped guide hole and move towards the fixture, thereby pushing the riveting edge with the riveting block to complete the riveting work. The mounting base is fixed to the frame for easy installation of the third cylinder. The hinge block allows the entire third cylinder to swing, adapting to the rotational motion of the rotating parts when the output rod of the third cylinder extends or retracts, avoiding interference. Multiple sets of screw holes are provided on the rotating ring, allowing the installation position of the positioning block to be changed according to actual conditions.

[0020] The aforementioned brake subassembly press machine can be further configured as follows: a slide bar is provided between the rivet block and the guide post, a wedge block is provided below the slide bar, a guide seat is fixed on the frame, a wedge groove is provided on the guide seat to fit the wedge block with clearance, a second strip hole is provided on the rivet block, and a screw hole is provided on the slide bar corresponding to the second strip hole.

[0021] Using the above technical solution, the sliding rod connects the rivet block and the guide post, transmitting the movement of the guide post to the rivet block, allowing the rivet block to move with the guide post and complete the riveting work. The clearance fit between the wedge groove and the wedge block not only allows the guide post to slide along the axial direction of the wedge groove (i.e., the strip-shaped sliding hole), but also prevents the rivet block from wobbling up and down. Through the second strip-shaped hole, the installation position of the rivet block can be adjusted according to the actual situation to change the position between the rivet block and the fixture, thus adapting to different specifications and types of brake assemblies.

[0022] The aforementioned brake subassembly press-fitting machine can be further configured as follows: the clamping device includes a lower connector and a second servo motor distributed at the lower end of the lower connector. The upper end of the lower connector is provided with an internal threaded hole. A linkage sleeve is provided between the lower connector and the second servo motor. The linkage sleeve is provided with a square sliding hole that extends through it along its own axis. The linkage sleeve is also provided with a guide strip groove distributed on the side of the square sliding hole. The guide strip groove and the square sliding hole are parallel to each other and communicate with each other. A pin is connected to the end of the lower connector. The end of the pin extends into the guide strip groove. The output end of the second servo motor is provided with a lower positioning block that cooperates with the square sliding hole. The lower end of the lower connector is provided with an upper positioning block. A return spring is provided in the square sliding hole. The two ends of the return spring are respectively sleeved on the outer periphery of the upper positioning block and the outer periphery of the lower positioning block.

[0023] Using the above technical solution, during the assembly of the threaded guide rod, the pressure head device presses the threaded guide rod down onto the fixture. Then, the second servo motor drives the lower connecting part to rotate. Since the lower connecting part has an internal threaded hole, the lower end of the threaded guide rod will be threadedly connected to the lower connecting part, that is, the threaded guide rod is limited. Even after the pressure rod mechanism rises, the threaded guide rod will not spring upward, which facilitates the assembly of the ball-bearing screw. Furthermore, the addition of a linkage sleeve, a square sliding hole, a guide strip groove, and a pin can stably realize the conversion of the rotation output form of the second servo motor into the rotation form of the lower connecting part, and also bring a certain degree of axial float to the lower connecting part (axial float: the second servo motor drives the linkage sleeve to rotate, and the lower connecting part follows the rotation of the linkage sleeve under the action of the pin. Due to the threaded connection between the lower connecting part and the threaded guide rod, the lower connecting part can also slide relative to the linkage sleeve along the axis of the guide strip groove), to adapt to the threaded connection method between the lower connecting part and the threaded guide rod.

Detailed Implementation

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] like Figures 1 to 15 The brake assembly press machine shown includes a frame, a clamp a1 mounted on the frame for clamping products, a press head device b distributed above the clamp a1, a clamping device c distributed below the clamp a1 for fixing products, and a riveting device a surrounding the clamp a1.

[0043] The pressing head device b includes a pressing turntable b5 and a first cylinder b1 distributed above the pressing turntable b5. A first through hole b2 is provided on the frame corresponding to the output end of the first cylinder b1. A first guide cylinder b3 is fixed at the first through hole b2, and a first sliding hole b4 passes through the first guide cylinder b3. The first sliding hole b4 in the first guide cylinder b3 replaces the first through hole b2 to cooperate with the output rod of the first cylinder b1, preventing the diameter of the first through hole b2 from increasing due to wear. Even if the diameter of the first sliding hole b4 increases due to wear, only the first guide cylinder b3 needs to be replaced; there is no need to replace the entire plate used for processing the first through hole b2. Simultaneously, the first guide cylinder b3 also guides the extension and retraction of the output rod of the first cylinder b1, improving the accurate correspondence between the first cylinder b1 and the first through hole b2, thereby accurately driving the pressing rod mechanism to perform the pressing action.

[0044] The pressure turntable b5 is linked to three sets of pressure rod mechanisms arranged sequentially and at intervals along the circumference of the pressure turntable b5. The pressure turntable b5 is also linked to a pressure turntable drive mechanism, which is used to drive the pressure turntable b5 to rotate.

[0045] The pressure turntable drive mechanism includes a belt b6 and drive pulleys b7 and driven pulleys b8 linked at both ends of the belt b6. The driven pulleys b8 are fixed below the pressure turntable b5, and each driven pulley b8 has a set of clearance holes corresponding to each set of pressure bar mechanisms. The drive pulley b7 is linked to a first servo motor b9. The first servo motor b9 drives the pressure turntable b5 to rotate through the drive pulley b7, belt b6, and driven pulleys b8, thereby changing the pressure bar mechanism.

[0046] The pressure turntable drive mechanism also includes an adjustment frame b10 and an adjustment bolt b11. The body of the first servo motor b9 is fixed on the adjustment frame b10. The adjustment frame b10 is provided with several sets of parallel first strip holes b12. Fasteners are connected to the first strip holes b12. The fasteners are detachably connected to the frame. The side of the adjustment frame b10 is provided with a T-slot b13. The cap of the adjustment bolt b11 is engaged in the T-slot b13. The rod of the adjustment bolt b11 is threadedly connected to a connecting block b14. The connecting block b14 is fixed on the frame and is provided with a connecting hole b27 that is threadedly connected to the adjustment bolt b11. When it is necessary to adjust the installation position of the pressure turntable drive mechanism, first loosen the fastener at the first strip hole b12 (the fastener can be a standard part such as a screw). Due to the structure of the T-slot b13, the adjustment bracket b10 can be removed directly. Then, rotate the adjustment bolt b11 according to the actual needs to change the extension length of the adjustment bolt b11 relative to the connecting block b14 until the required length is reached. Then, lock the T-slot b13 of the adjustment bracket b10 into the cap of the adjustment bolt b11. Finally, use the fastener and the first strip hole b12 to fix the adjustment component on the frame.

[0047] The frame is also equipped with a positioning assembly for positioning the pressure turntable b5. The positioning assembly includes a positioning rod b15 and a second cylinder b16 that is linked to the positioning rod b15. A set of positioning holes b17 on the pressure turntable b5 is distributed between each pair of adjacent pressure rod mechanisms. A set of positioning sleeves b18 is installed at each positioning hole b17. The end of the positioning rod b15 away from the second cylinder b16 is tapered. A second guide cylinder b19 is provided on the frame corresponding to the positioning rod b15, and a second sliding hole b20 passes through the second guide cylinder b19. The second sliding hole b20 in the second guide cylinder b19 guides the extension and retraction of the positioning rod b15 (the second cylinder b16 drives the positioning rod b15 to reciprocate), further improving the accurate correspondence between the positioning rod b15 and the positioning sleeve b18, thereby ensuring that the pressure turntable b5 is stably maintained in the working position. During the pressing process, the positioning assembly, through the cooperation of the positioning rod b15 and the positioning sleeve b18, can stably hold the pressing turntable b5 in the working state, preventing the pressing turntable b5 from rotating or shifting, and ensuring that each set of pressing rod mechanisms can accurately align with the first sliding hole b4, thereby achieving precise pressing action. When it is necessary to change the pressing rod mechanism, the second cylinder b16 controls the positioning rod b15 to retract from the positioning sleeve b18, and the pressing turntable b5 can then rotate. The end of the positioning rod b15 is tapered, which facilitates the insertion of the positioning rod b15 into the positioning sleeve b18. By setting the positioning sleeve b18 to replace the positioning hole b17 for cooperation with the positioning rod b15, excessive wear of the pressing turntable b5 is avoided, extending its service life.

[0048] The pressure rod mechanism includes a hollow guide sleeve b21 with openings at both ends. The pressure turntable b5 has three sets of second through holes b22. The upper end of each guide sleeve b21 is installed within one set of second through holes b22. A pressure rod b23 is slidably connected within the guide sleeve b21. The pressure rod b23 is linked to a reset component, and the lower end of the pressure rod b23 is linked to a clamping component b24 capable of clamping the processed product. The reset component includes a spring sleeved around the outer periphery of the pressure rod b23. An upper flange b25 is fixed to the upper end of the pressure rod b23, and the upper flange b25 is clearance-fitted with the guide sleeve b21. A lower flange b26, opposite to the upper flange b25, is fixed within the guide sleeve b21. One end of the spring abuts against the upper flange b25, and the other end abuts against the lower flange b26. Through the cooperation of the guide sleeve b21 and the second through holes b22 on the pressure turntable b5, precise positioning of the pressure rod b23 is achieved, ensuring accuracy during the pressing process. Because the pressure turntable b5 can rotate until different guide sleeves b21 correspond to the first through hole b2, different pressure rod mechanisms can be quickly switched, improving work efficiency. Since the clamping part b24 can be replaced according to different processed products, this pressure-setting device can adapt to processed products of different shapes and sizes, increasing the device's applicability. A spring ensures that the pressure rod b23 automatically resets after pressure-setting. The hollow guide sleeve b21 design makes the device compact, space-saving, and easy to integrate into existing production lines. The specific operation is as follows: The pressure turntable b5 rotates under the drive of the pressure turntable drive mechanism. Different guide sleeves b21 will correspond to the second through hole b22. Only one set of guide sleeves b21 corresponds to the first through hole b2 at a time. The output end of the first cylinder b1 passes through the first through hole b2 and pushes the pressure rod b23 down. The lower part of the pressure rod b23 is equipped with a clamping part b24 for clamping the processed product. After pressure-setting is completed, the first cylinder b1 resets, and the pressure rod b23 automatically resets under the action of the spring.

[0049] A clamping component b24 has a connecting hole b27 at its upper end, and a insert b28 that mates with the connecting hole b27 at its lower end. The clamping component b24 also has a countersunk hole b25 at its lower end, and several sets of notches spaced apart around the countersunk hole b25. By providing the connecting hole b27 and the insert b28, a detachable connection between the clamping component b24 and the pressure rod b23 can be achieved. The countersunk hole b25 and the notches further facilitate the clamping component b24 in clamping the threaded guide rod on the brake subassembly.

[0050] A clamping component b24 has a connecting hole b27 at its upper end, and a plug b28 that mates with the connecting hole b27 at its lower end. The clamping component b24 also has a cylindrical insertion hole b26 at its lower end, and guide insertion holes b27 distributed on the sides of the cylindrical insertion hole b26. By providing the connecting hole b27 and the plug b28, a detachable connection between the clamping component b24 and the pressure rod b23 can be achieved. The cylindrical insertion hole b26 is further provided to facilitate the insertion of the ball bearing screw; the guide insertion holes b27 are provided for positioning during the clamping of the ball bearing screw, ensuring that the ball bearing screw is pressed in the correct direction.

[0051] A clamping component b24 has a connecting hole b27 at its upper end, and a pressure rod b23 has an insert b28 at its lower end that mates with the connecting hole b27. Several sets of riveting blocks b28 are evenly distributed on the lower end face of the clamping component b24, arranged sequentially and at intervals along its circumference. By providing the connecting hole b27 and the insert b28, a detachable connection between the clamping component b24 and the pressure rod b23 can be achieved. Further, the riveting blocks b28 are provided to rivet the outer edge of the brake sub-assembly.

[0052] The riveting device a includes a rotating ring a2, a ring plate a6 fixedly connected to the rotating ring a2, a limiting ring a7, and a rotary drive mechanism for controlling the rotation of the rotating parts. The limiting ring a7 is sleeved on the outer circumference of the rotating ring a2 with a clearance fit. The limiting ring a7 constrains and guides the rotational movement of the rotating ring a2. During the rotation of the rotating ring a2, the limiting ring a7 can prevent the rotating ring a2 from undergoing axial or radial displacement, ensuring more stable rotational movement of the rotating ring a2.

[0053] The rotating ring a2 has multiple sets of screw holes arranged at intervals along its circumference. A positioning block a3 is detachably connected to the rotating ring a2 via these screw holes. A ring plate a6 is located below the rotating ring a2 and has a slanted sliding groove a4. A third through hole a5 is located in the center of the rotating ring a2. The ring plate a6, positioned below the rotating ring a2, provides a mounting surface for the slanted sliding groove a4. The multiple sets of screw holes on the rotating ring a2 allow the mounting position of the positioning block a3 to be changed according to actual needs.

[0054] The rotary drive mechanism includes a third cylinder a8 and a push rod a9 hinged to the output end of the third cylinder a8. The body of the third cylinder a8 is hinged with a hinge block a9, which is fixed to a mounting base a10. The mounting base a10 is distributed on the side of the rotating ring a2 and fixed to the frame. A positioning block a3 is linked to the push rod a9. The mounting base a10 is fixed to the frame for easy installation of the third cylinder a8. The hinge block a9 allows the third cylinder a8 to swing as a whole, adapting to the rotational movement of the rotating parts when the output rod of the third cylinder a8 extends or retracts, thus avoiding interference.

[0055] The fixture a1 is located in the middle of the third through hole a5. Three sets of rivet blocks a11 are arranged between the rotating ring a2 and the fixture a1. These sets of rivet blocks a11 are arranged sequentially at intervals along the circumference of the fixture a1. Guide posts a12 are linked to the ends of the rivet blocks a11 furthest from the fixture a1. The frame has a set of strip-shaped guide holes a18 that are clearance-fitted to each guide post a12. The guide posts a12 are arranged radially along the rotating component. Each set of inclined slide grooves a4 corresponds to a set of guide posts a12. The inclined slide grooves a4 are located on the rotating ring a2. When the rotary drive mechanism drives the rotating ring a2 to rotate, the inclined slide grooves a4 rotate accordingly. The inclined structure of the inclined slide grooves a4 converts the rotational motion of the rotating component into a thrust on the guide posts a12, causing the guide posts a12 to move within the strip-shaped guide holes a18 and move closer to the fixture a1. This causes the rivet blocks a11 to push the riveting edge, completing the riveting work.

[0056] A sliding rod a13 is provided between the rivet block a11 and the guide post a12. A wedge block a14 is provided below the sliding rod a13. A guide seat a15 is fixed on the frame, and the guide seat a15 has a wedge groove a16 that is clearance-fitted with the wedge block a14. The sliding rod a13 connects the rivet block a11 and the guide post a12, transmitting the movement of the guide post a12 to the rivet block a11, so that the rivet block a11 can move with the movement of the guide post a12 to complete the riveting work. The clearance fit between the wedge groove a16 and the wedge block a14 not only allows the guide post a12 to slide along the axial direction of the wedge groove a16 (i.e., the strip-shaped sliding hole), but also prevents the rivet block a11 from wobbling up and down.

[0057] The rivet block a11 has a second strip hole a17, and the slide rod a13 has a screw hole corresponding to the second strip hole a17. Through the second strip hole a17, the installation position of the rivet block a11 can be adjusted according to the actual situation to change the position between the rivet block a11 and the clamp a1, so as to adapt to different specifications and types of brake assemblies.

[0058] Working principle of riveting device A: When the piston rod of the third cylinder A8 extends or retracts, the push rod A9 not only moves back and forth relative to the body of the third cylinder A8, but also swings along with the third cylinder A8 as a whole, ultimately converting it into the rotation of the rotating ring A2, and the inclined slide groove A4 rotates accordingly. The inclined structure of the inclined slide groove A4 converts the rotational motion of the rotating ring A2 into a thrust on the guide post A12, causing the guide post A12 to move within the strip-shaped guide hole A18 and move closer to the clamp A1, thereby pushing the riveting edge with the riveting block A11 to complete the riveting work.

[0059] The clamping device c includes a lower connector c1 and a second servo motor c2 located at the lower end of the lower connector c1. The upper end of the lower connector c1 is provided with an internal threaded hole c3. A linkage sleeve c10 is provided between the lower connector c1 and the second servo motor c2. The linkage sleeve c10 is provided with a square sliding hole c4 that extends through along its own axis. The linkage sleeve c10 is also provided with a guide strip groove c5 located on the side of the square sliding hole c4. The guide strip groove c5 and the square sliding hole c4 are parallel to each other and communicate with each other. A pin c6 is connected to the end of the lower connector c1. The end of the pin c6 extends into the guide strip groove c5. The output end of the second servo motor c2 is provided with a lower positioning block c7 that cooperates with the square sliding hole c4. The lower end of the lower connector c1 is provided with an upper positioning block c8. A return spring c9 is provided in the square sliding hole c4. The two ends of the return spring c9 are respectively sleeved on the outer periphery of the upper positioning block c8 and the outer periphery of the lower positioning block c7.

[0060] When assembling the threaded guide rod, the pressure head device b is used to press the threaded guide rod down onto the fixture a1. Then, the second servo motor c2 drives the lower connecting piece c1 to rotate. Since the lower connecting piece c1 is provided with an internal threaded hole c3, the lower end of the threaded guide rod will be threadedly connected to the lower connecting piece c1. That is, the threaded guide rod is limited. Even if the pressure rod mechanism rises, the threaded guide rod will not bounce up, which facilitates the assembly of the steel ball sleeve screw. Furthermore, by adding a linkage sleeve c10, a square sliding hole c4, a guide groove c5, and a pin c6, the rotation output of the second servo motor c2 can be stably converted into the rotation of the lower connector c1. This also introduces a certain degree of axial floating to the lower connector c1 (axial floating: the second servo motor c2 drives the linkage sleeve c10 to rotate, and the lower connector c1 rotates with the linkage sleeve c10 under the action of the pin c6. Due to the threaded connection between the lower connector c1 and the threaded guide rod, the lower connector c1 can slide relative to the linkage sleeve c10 along the axial direction of the guide groove c5), to adapt to the threaded connection between the lower connector c1 and the threaded guide rod.

[0061] This embodiment describes the specific operation when applied to a brake subassembly:

[0062] Using a human hand or a robotic arm, place the spring seat on fixture a1, place the threaded guide rod on a set of pressure rod mechanisms, and place the steel ball sleeve screw on another set of pressure rod mechanisms;

[0063] The pressure rod mechanism equipped with the threaded guide rod moves down to complete the press-fitting of the threaded guide rod;

[0064] Then, clamping device c limits the threaded guide rod, so that even if the pressure rod mechanism rises, the threaded guide rod will not spring upward under the action of the spring.

[0065] Next, the ball bearing sleeve screw pressure rod mechanism moves with the pressure plate turntable b5 to correspond to the first through hole b2. The ball bearing sleeve screw pressure rod mechanism moves downward. After the ball bearing sleeve screw reaches the predetermined position, the pressure rod mechanism does not rise temporarily.

[0066] Then, the riveting device a operates to rivet the outer edge of the spring seat sleeve, and the steel ball sleeve screw connects with the spring seat sleeve. Then, the pressure rod mechanism rises.

[0067] Next, the clamping mechanism with the rivet block b20 is installed and moves with the pressure plate b5 to correspond to the first through hole b2. The pressure mechanism moves down to further compact the rivet edge, and finally completes the assembly of the brake sub-assembly.

[0068] As can be directly seen from the specific operation, this specific embodiment does not require multiple product runs, enabling multi-stage press-fitting of the brake subassembly. It eliminates the need for multiple machines and repeated product runs, facilitating the assembly of the brake subassembly and improving production efficiency. Furthermore, during the entire assembly process, the ball bearing screw will not wobble left or right, nor will it move up or down, and the threaded guide rod will not move up or down.
