Description

Technical Field

[0001] This invention relates to the field of automotive brakes, and in particular to a spline pusher assembly system. Background Technology

[0002] Wedge brakes are increasingly being used in vehicles due to their advantages such as light weight, fast response speed, and low failure rate. The wedge assembly is an important key component of the wedge brake, which can automatically adjust the braking clearance and ensure good braking force matching, thereby improving the braking efficiency and braking stability of the wedge brake.

[0003] A wedge assembly generally includes several components such as a wheel cylinder block, a spline push block assembly, a guide ring, a spring assembly, a retaining ring for the bore, and a push rod assembly. The spline push block assembly is composed of several components such as a spline push block, a clutch spring, a wedge-shaped push block, and a flattened wire retaining ring.

[0004] When machining a spline pusher assembly, the required spline pusher, clutch spring, wedge pusher, and flattened wire retaining ring are typically machined separately first. These components are then assembled to form the final spline pusher assembly. Currently, most spline pusher assembly assembly is done manually, which is labor-intensive. Furthermore, the flattened wire retaining ring is relatively small and thin-walled, and it is usually black, making it easy to miss components during manual assembly. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a spline push block assembly system that facilitates spline push block assembly and avoids missing spline push block components.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is: a spline pusher assembly assembly system, wherein the spline pusher assembly includes a spline pusher, a clutch spring, a wedge-shaped pusher, and a flattened steel wire retaining ring. Its innovation lies in: the assembly system includes...

[0007] A spline push block assembly bracket is defined as follows: one of the horizontal directions of the spline push block assembly bracket is defined as the first direction, and the horizontal direction perpendicular to the first direction is defined as the second direction.

[0008] A spline push block feeding conveyor belt and a wedge push block feeding conveyor belt are respectively provided on both sides of the spline push block assembly assembly bracket in the first direction, and the spline push block feeding conveyor belt and the wedge push block feeding conveyor belt have the same conveying direction. A material gripping unit is provided on the side of the spline push block assembly assembly bracket in the second direction, and the material gripping unit is located at the outlet of the spline push block feeding conveyor belt and the wedge push block feeding conveyor belt.

[0009] The material gripping unit includes a material gripping bracket mounted on a spline push block assembly bracket, and spline push block gripping components and wedge push block gripping components arranged in parallel along the second direction are mounted on the material gripping bracket.

[0010] The spline push block assembly bracket is also equipped with a spline push block transfer assembly, a retaining ring assembly assembly, and a spinning assembly that are distributed sequentially along the second direction.

[0011] Furthermore, the spline push block gripping assembly includes a spline push block gripping seat and a first gripping electromagnet. The first gripping electromagnet is driven to move up and down by a second lifting cylinder installed on the spline push block gripping seat. The spline push block gripping seat is driven to reciprocate along a first direction by a first horizontal cylinder installed on the gripping bracket.

[0012] The material gripping bracket is also equipped with a pair of first guide rails arranged in parallel along the second direction. The first guide rails extend along the second direction, and first sliders that cooperate with the first guide rails are also installed on both sides of the bottom surface of the spline push block gripping seat.

[0013] The wedge-shaped push block gripping assembly includes a wedge-shaped push block gripping seat and a second gripping electromagnet. The second gripping electromagnet is driven to move up and down by a third lifting cylinder installed on the wedge-shaped push block gripping seat. The wedge-shaped push block gripping seat is driven to reciprocate along a first direction by a second horizontal cylinder installed on the gripping bracket.

[0014] The material gripping bracket is also equipped with a pair of second guide rails arranged in parallel along the second direction. The second guide rails extend along the second direction, and second sliders that cooperate with the second guide rails are also installed on both sides of the bottom surface of the wedge-shaped push block gripping seat.

[0015] The retaining ring assembly assembly includes a retaining ring assembly bracket mounted on a spline push block assembly bracket, and a retaining ring assembly platform mounted on the retaining ring assembly bracket. The retaining ring assembly platform is driven to move up and down by a fourth lifting cylinder.

[0016] The retaining ring assembly platform has an opening that runs vertically through the entire platform and allows the flattened wire retaining ring to pass through. The opening is frustum-shaped, with the upper base of the opening being larger than the lower base. The outer wall of the flattened wire retaining ring is smaller than the upper base of the opening but larger than the lower base. A retaining ring placement seat for stacking flattened wire retaining rings is also installed on the side of the opening on the retaining ring assembly platform. A retaining ring pusher is also provided between the retaining ring placement seat and the retaining ring assembly platform. An arc-shaped notch for placing a single flattened wire retaining ring is opened on one side of the retaining ring pusher. The retaining ring pusher is driven by a seventh horizontal cylinder installed on the retaining ring assembly platform to reciprocate between the retaining ring placement seat and the opening on the retaining ring assembly platform.

[0017] A retaining ring pressing assembly is also provided above the opening on the retaining ring assembly platform. The retaining ring pressing assembly includes a retaining ring pressing plate, a retaining ring pressing column, and a seventh lifting cylinder. The retaining ring pressing plate is located above the retaining ring assembly platform. The seventh lifting cylinder is installed upside down on the retaining ring pressing plate. A vertically arranged retaining ring pressing column is connected to the front end of the piston rod of the seventh lifting cylinder. The retaining ring pressing column is driven by the seventh lifting cylinder to move up and down, thereby passing through the opening on the retaining ring assembly platform.

[0018] Below the retaining ring assembly platform, there is a spline push block placement seat. The upper end of the spline push block placement seat has a groove for placing the spline push block, and after the spline push block is placed in the groove, the upper part of the spline push block extends out of the groove.

[0019] The spline push block transfer assembly includes a pair of third guide rails, a first transfer seat, and a third clamp, all disposed on one side of the retaining ring assembly bracket. The two third guide rails are arranged side by side along a second direction and extend along a first direction. A third slider that cooperates with the third guide rails is installed at the bottom of the first transfer seat. The first transfer seat is driven by a first linear motor mounted on the spline push block assembly bracket to move horizontally along the third guide rails. The third clamp is disposed on the side of the third guide rails away from the retaining ring assembly bracket. The third clamp is driven by a third clamping cylinder to move closer to or further away from each other. The third clamping cylinder is driven by a fifth horizontal cylinder to move closer to or further away from the retaining ring assembly bracket. The fifth horizontal cylinder is driven by a fifth lifting cylinder to move up and down, thereby driving the third clamp to perform horizontal and vertical movements.

[0020] The spinning assembly includes a pair of fourth guide rails, a second transfer seat, a spline push block chuck, and a fourth clamp, all located on the other side of the retaining ring assembly bracket. The two fourth guide rails are arranged side by side along a second direction and extend along a first direction. A fourth slider that mates with the fourth guide rails is installed at the bottom of the second transfer seat. The second transfer seat is driven by a second linear motor mounted on the spline push block assembly bracket to move horizontally along the fourth guide rails. The spline push block chuck is mounted on the second transfer seat and is driven to rotate by a rotary motor mounted on the second transfer seat. The fourth clamp is located on the side of the fourth guide rail away from the retaining ring assembly bracket. The fourth clamp is driven by a fourth clamping cylinder to move closer to or further away from each other. The fourth clamping cylinder is driven by a sixth horizontal cylinder to move closer to or further away from the retaining ring assembly bracket. The sixth horizontal cylinder is driven by a sixth lifting cylinder mounted on the spline push block assembly bracket to move up and down, thereby driving the fourth clamp to perform horizontal and vertical movements.

[0021] Furthermore, the cooperation between the retaining ring assembly platform, the fourth lifting cylinder, and the retaining ring assembly bracket is as follows: four vertically arranged first guide posts are installed on the retaining ring assembly bracket; a first guide hole is opened on the retaining ring assembly platform to allow the first guide posts to pass through and move vertically; a first guide sleeve is also installed at the first guide hole; there are two fourth lifting cylinders, distributed along the first direction on both sides of the retaining ring assembly platform; a lifting seat is also installed at the top of the fourth lifting cylinder; the lifting seat is cylindrical; circular baffles are connected to the upper and lower sides of the lifting seat, and the diameter of the circular baffles is larger than the diameter of the lifting seat; U-shaped openings are also opened on both sides of the retaining ring assembly platform to allow the lifting seat to be inserted; after the lifting seat is inserted into the U-shaped opening of the retaining ring assembly platform, the two circular baffles are located on the upper and lower sides of the retaining ring assembly platform, respectively.

[0022] Furthermore, the retaining ring placement seat includes a retaining ring column and a column fixing frame for fixing the retaining ring column. The retaining ring column is composed of a long strip and a cylindrical section connected together, and the width of the long strip is smaller than the diameter of the cylindrical section. The column fixing frame is U-shaped. The long strip of the retaining ring column is connected to the column fixing frame. A gap is left between the bottom end face of the retaining ring column and the retaining ring assembly platform to allow the retaining ring push block to pass through and slide horizontally.

[0023] Furthermore, a guide seat is installed at the bottom of the retaining ring assembly platform at the opening. The guide seat has a through hole for the retaining ring pressure post to pass through and move up and down. A downwardly protruding circular positioning boss is also provided on the bottom end surface of the retaining ring pressure post. The outer wall of the positioning boss is in contact with the inner wall of the flattened steel wire retaining ring.

[0024] The advantages of this invention are as follows: The assembly system of this invention achieves semi-automatic assembly of the spline push block assembly through the cooperation of the spline push block assembly bracket, the spline push block feeding conveyor belt, the wedge push block feeding conveyor belt, the material gripping unit, the spline push block transfer component, the retaining ring assembly component, and the spinning component. This reduces the number of manual assembly steps, greatly reduces manual labor, and avoids the phenomenon of missing parts that occur during manual assembly, thus ensuring smooth assembly.

[0025] The lifting mechanism of the retaining ring assembly platform is achieved by using the lifting seat on the fourth lifting cylinder, the circular baffle, and the U-shaped openings on both sides of the retaining ring assembly platform. This method eliminates the need for bolts, pins, or other connecting parts to fix the fourth lifting cylinder and the retaining ring assembly platform, making installation and subsequent disassembly and maintenance convenient.

[0026] The design of the retaining ring placement seat adopts a combination structure of retaining ring column and column fixing frame, which facilitates subsequent cooperation with retaining ring push block to realize the feeding of individual flattened steel wire retaining rings, and provides a good foundation for the automatic assembly of flattened steel wire retaining rings and spline push block. The retaining ring column adopts a combination structure of long strip and cylindrical sections, which facilitates the stacking and storage of flattened steel wire retaining rings.

[0027] The guide seat at the bottom of the retaining ring assembly platform is designed to guide the retaining ring pressure column during its up-and-down movement, preventing it from deviating. The positioning boss on the bottom surface of the retaining ring pressure column is designed to cooperate with the flattened wire retaining ring, providing a positioning and holding function. This ensures that the flattened wire retaining ring deforms regularly when passing through the opening on the retaining ring assembly platform, preventing irregular deformation that could affect the subsequent connection between the flattened wire retaining ring and the spline push block.

[0036] The following embodiments are intended to enable those skilled in the art to more fully understand the present invention, but do not limit the invention to the scope of the embodiments described.

[0037] like Figures 1-7The figure shows a spline pusher assembly system, the spline pusher assembly includes a spline pusher 101, a clutch spring, a wedge-shaped pusher and a flattened wire retainer 102, the flattened wire retainer 102 being C-shaped.

[0038] Assembly system includes

[0039] A spline push block assembly bracket 2 is a hollow cuboid frame structure composed of several horizontal profiles, longitudinal profiles and vertical profiles. One of the horizontal directions of the spline push block assembly bracket 2 is defined as the first direction, and the horizontal direction perpendicular to the first direction is defined as the second direction.

[0040] On both sides of the spline pusher assembly assembly bracket 2 in the first direction, there is a spline pusher 101 feeding conveyor belt 201 for feeding spline pushers 101 and a wedge pusher 202 for feeding wedge pushers. The spline pusher 101 feeding conveyor belt 201 and the wedge pusher 202 feeding conveyor belt 202 have the same feeding direction. The spline pusher 101 feeding conveyor belt 201 is mounted on a spline pusher 101 feeding conveyor bracket and is driven by a motor mounted on the spline pusher 101 feeding conveyor bracket. The wedge pusher 202 feeding conveyor belt 202 is mounted on a wedge pusher 202 feeding conveyor bracket and is driven by a motor mounted on the wedge pusher 202 feeding conveyor bracket. A material gripping unit is provided on the side of the spline pusher assembly assembly bracket 2 in the second direction. The material gripping unit is located at the outlet of the spline pusher 102 feeding conveyor belt 202 and the wedge pusher 202 feeding conveyor belt 202.

[0041] The material gripping unit includes a material gripping bracket 203 mounted on the spline push block assembly bracket 2. The material gripping bracket 203 is a gantry structure formed by connecting a horizontal profile and a pair of vertical profiles. One side of the spline push block feeding conveyor belt 201 and the wedge push block feeding conveyor belt 202 extends to the bottom of the material gripping bracket 203. The spline push block gripping assembly and the wedge push block gripping assembly are mounted on the material gripping bracket 203 and arranged in parallel along the second direction.

[0042] The spline push block gripping assembly includes a spline push block gripping seat 204 and a first gripping electromagnet. The first gripping electromagnet is driven to move up and down by a second lifting cylinder 205 mounted on the spline push block gripping seat 204. The second lifting cylinder 205 is mounted upside down on the spline push block gripping seat 204. The first gripping electromagnet is connected to the front end of the piston rod of the second lifting cylinder 205 and drives the first gripping electromagnet to move up and down. The spline push block gripping seat 204 is driven to reciprocate along a first direction by a first horizontal cylinder 206 mounted on the gripping bracket 203.

[0043] A pair of first guide rails 207 are also installed on the horizontal profile of the material gripping bracket 203, which are arranged in parallel along the second direction. The first guide rails 207 extend along the second direction. On both sides of the bottom surface of the spline push block gripping seat 204, first sliders 208 that cooperate with the first guide rails 207 are also installed. The first horizontal cylinder 206 is installed on the horizontal profile of the material gripping bracket 203, and the piston rod of the first horizontal cylinder 206 is connected to the spline push block gripping seat 204, thereby driving the spline push block gripping seat 204 to move horizontally along the first guide rails 207.

[0044] The wedge-shaped push block gripping assembly includes a wedge-shaped push block gripping seat 210 and a second gripping electromagnet. The second gripping electromagnet is driven to move up and down by a third lifting cylinder 211 mounted on the wedge-shaped push block gripping seat 210. The third lifting cylinder 211 is inverted and mounted on the wedge-shaped push block gripping seat 210. The front end of the piston rod of the third lifting cylinder 211 is connected to the second gripping electromagnet and drives the second gripping electromagnet to move up and down. The wedge-shaped push block gripping seat 210 is driven to reciprocate along a first direction by a second horizontal cylinder 212 mounted on the material gripping bracket 203.

[0045] A pair of second guide rails 213 are also installed on the horizontal profile of the material gripping bracket 203, which are arranged in parallel along the second direction. The second guide rails 213 extend along the second direction. On both sides of the bottom surface of the wedge-shaped push block gripping seat 210, second sliders 214 that cooperate with the second guide rails 213 are also installed. The second horizontal cylinder 212 is installed on the horizontal profile of the material gripping bracket 203. The piston rod of the second horizontal cylinder 212 is connected to the wedge-shaped push block gripping seat 210 and drives the wedge-shaped push block gripping seat 210 to move horizontally reciprocating along the second guide rails 213.

[0046] The spline push block assembly bracket 2 is also equipped with a spline push block transfer assembly, a retaining ring assembly assembly, and a spinning assembly that are distributed sequentially along the second direction.

[0047] The retaining ring assembly assembly includes a retaining ring assembly bracket 220 mounted on the spline push block assembly bracket 2. The bottom end of the retaining ring assembly bracket 220 is fixed to the spline push block assembly bracket 2 by bolts. A retaining ring assembly platform 221 is mounted on the retaining ring assembly bracket 220. The retaining ring assembly platform 221 is a rectangular plate and is driven to move up and down by a pair of fourth lifting cylinders 222.

[0048] The cooperation between the retaining ring assembly platform 221, the fourth lifting cylinder 222, and the retaining ring assembly bracket 220 is as follows: four vertically arranged first guide posts 223 are installed on the retaining ring assembly bracket 220, and the four first guide posts 223 are arranged in a U-shape. The retaining ring assembly platform 221 is also provided with first guide holes that allow each first guide post 223 to pass through and move vertically. A first guide sleeve 226 is also installed at each first guide hole on the retaining ring assembly platform 221, and the first guide post 223 passes through the first guide sleeve 226.

[0049] There are two fourth lifting cylinders 222, distributed along the first direction on both sides of the retaining ring assembly platform 221. A lifting seat 224 is also installed at the top of the fourth lifting cylinder 222. The lifting seat 224 is cylindrical. Circular baffles 225 are connected to the upper and lower sides of the lifting seat 224, and the diameter of the circular baffles 225 is larger than the diameter of the lifting seat 224, so that the circular baffles 225 and the lifting seat 224 are connected to form an I-shaped structure. U-shaped openings for the lifting seat 224 to be inserted are also opened on both sides of the retaining ring assembly platform 221. After the lifting seat 224 is inserted into the U-shaped opening of the retaining ring assembly platform 221, the two circular baffles 225 are located on the upper and lower sides of the retaining ring assembly platform 221, respectively, thereby limiting the relative position between the lifting seat 224 and the retaining ring assembly platform 221. The lifting mechanism of the retaining ring assembly platform 221 is achieved by using the lifting seat 224 on the fourth lifting cylinder 222, the circular baffle 225, and the U-shaped openings on both sides of the retaining ring assembly platform 221. This method eliminates the need for bolts, pins, or other connecting parts to fix the fourth lifting cylinder 222 and the retaining ring assembly platform 221, thus facilitating the installation of the retaining ring assembly platform 221 and subsequent disassembly and maintenance.

[0050] An opening 227 is provided on the retaining ring assembly platform 221, extending vertically through the entire platform and accommodating the flattened wire retaining ring. The opening 227 is frustum-shaped, with the upper base of the opening 227 being larger than the lower base. The outer wall of the flattened wire retaining ring 102 is smaller than the upper base of the opening 227 but larger than the lower base. This design allows the flattened wire retaining ring 102 to fall smoothly into the opening 227 in its natural state, while also ensuring that it does not fall directly out from the bottom of the opening 227. A retaining ring placement seat for stacking and storing the flattened wire retaining rings 102 is also installed on the retaining ring assembly platform 221 next to the opening 227. A retaining ring pusher 231 is also provided between the retaining ring placement seat and the retaining ring assembly platform 221.

[0051] The retaining ring placement seat includes a retaining ring column and a column fixing bracket 228 for fixing the retaining ring column. The retaining ring column is jointly connected by a long strip section 229 and a cylindrical section 230. The width of the long strip section 229 is smaller than the diameter of the cylindrical section 230. The diameter of the cylindrical section 230 is consistent with the inner diameter of the flattened wire retaining ring 102. The width of the long strip section 229 is consistent with the size at the C-shaped notch of the flattened wire retaining ring 102. This enables the flattened wire retaining rings 102 to be stacked on the cylindrical section 230 smoothly in sequence. The column fixing bracket 228 is in a U-shaped form and is fixed on the retaining ring assembly platform 221 through the cooperation of bolts. The long strip section 229 of the retaining ring column is connected to one side surface of the column fixing bracket 228, and there is a gap between the bottom end surface of the retaining ring column and the retaining ring assembly platform 221 for the retaining ring pusher block 231 to pass through and slide horizontally. At the same time, there is also a gap between the bottom end of one side surface of the column fixing bracket 228, which is connected to the long strip section 229, and the retaining ring assembly platform 221 for the retaining ring pusher block 231 to pass through and slide horizontally. For the design of the retaining ring placement seat, a combined structure of the retaining ring column and the column fixing bracket 228 is adopted, which is convenient for subsequent cooperation with the retaining ring pusher block 231 to realize the feeding of a single flattened wire retaining ring 102, providing a good foundation for the subsequent automatic assembly of the flattened wire retaining ring 102 and the spline pusher block 101. For the retaining ring column, a combined structure of the long strip section 229 and the cylindrical section 230 is adopted, which is convenient for the stacking and storage of the flattened wire retaining rings 102.

[0052] An arc-shaped notch for placing a single flattened wire retaining ring 102 is opened on one side of the retaining ring pusher block 231. The retaining ring pusher block 231 is driven by a seventh horizontal cylinder installed on the retaining ring assembly platform 221 to reciprocate and slide between the retaining ring placement seat and the opening 227 on the retaining ring assembly platform 221, so as to push a single flattened wire retaining ring 102 to translate and fall into the opening 227 from the retaining ring placement seat.

[0053] A retaining ring pressing component is further provided above the opening 227 on the retaining ring assembly platform 221. The retaining ring pressing component includes a retaining ring pressing plate 232, a retaining ring pressing column, and a seventh lifting cylinder 233. The retaining ring pressing plate 232 is a rectangular plate and is located above the retaining ring assembly platform 221. Both sides of the retaining ring pressing plate 232 are fixed on the retaining ring assembly platform 221 through connecting columns. The seventh lifting cylinder 233 is installed upside down on the retaining ring pressing plate 232. A vertically arranged retaining ring pressing column 234 is connected to the front end of the piston rod of the seventh lifting cylinder 233. The retaining ring pressing column 234 is driven by the seventh lifting cylinder 233 to move up and down, so as to pass through the opening 227 on the retaining ring assembly platform 221.

[0054] The upper end of the retaining ring pressure column 234 is connected to the piston rod of the seventh lifting cylinder 233 through a flange. A guide seat 235 is also installed at the bottom of the retaining ring assembly platform 211 at the opening 227. The guide seat 235 is fixed to the bottom surface of the retaining ring assembly platform 221 by bolts. The guide seat 235 has a through hole that allows the retaining ring pressure column 234 to pass through and move up and down. A downwardly protruding circular positioning boss 236 is also provided on the bottom end face of the retaining ring pressure column 234. The outer wall of the positioning boss 236 fits against the inner wall of the flattened steel wire retaining ring 102. When the positioning boss 236 passes through the guide seat 235, there is a gap between the positioning boss 236 and the guide seat 235 to accommodate a single flattened steel wire retaining ring 102. The guide seat 235 at the bottom of the retaining ring assembly platform 221 is designed to guide the retaining ring pressure column 234 during its up-and-down movement, preventing it from deviating. The positioning boss 236 on the bottom surface of the retaining ring pressure column 234 is designed to cooperate with the flattened wire retaining ring 102, providing a positioning and holding function for the flattened wire retaining ring 102. This ensures that the flattened wire retaining ring 102 deforms regularly when passing through the opening 227 on the retaining ring assembly platform 221, preventing irregular deformation that could affect the subsequent connection between the flattened wire retaining ring 102 and the spline push block 101.

[0055] Below the retaining ring assembly platform 221, there is also a spline push block placement seat 240. The upper end of the spline push block placement seat 240 has a groove for placing the spline push block 101, and after the spline push block 101 is placed in the groove, the upper part of the spline push block 101 extends out of the groove.

[0056] The spline push block transfer assembly includes a pair of third guide rails 241, a first transfer seat 242, and a third clamp 243 disposed on one side of the retaining ring assembly bracket 220. The two third guide rails 241 are arranged side by side along the second direction and extend along the first direction to the bottom of the gripping bracket 203. A third slider that cooperates with the third guide rails 241 is installed at the bottom of the first transfer seat 242. The first transfer seat 242 is driven by a first linear motor mounted on the spline push block assembly bracket 2 to move horizontally along the third guide rails 243. A pneumatic three-jaw chuck for clamping the spline push block 101 is installed at the top of the first transfer seat 242.

[0057] The third clamp 243 is located on the side of the third guide rail 241 away from the retaining ring assembly bracket 220, and the height of the third clamp 243 is higher than the height of the pneumatic three-jaw chuck at the top of the first transfer seat 242. The third clamp 243 is driven by the third clamping cylinder 245 to move closer or further away from each other. The third clamping cylinder 245 is driven by the fifth horizontal cylinder 246 to move closer or further away from the retaining ring assembly bracket 220. The fifth horizontal cylinder 246 is driven by the fifth lifting cylinder 247 to move up and down. The bottom end of the fifth horizontal cylinder 246 is fixed to the spline push block assembly bracket 2 through the first cylinder mounting seat 248. The cooperation of the fifth horizontal cylinder 246 and the fifth lifting cylinder 247 drives the third clamp 243 to perform horizontal and vertical movements, so that the third clamp 243 can clamp the spline push block 101 to move horizontally and move up and down.

[0058] The spinning assembly includes a pair of fourth guide rails 250, a second transfer seat 251, a spline push block chuck 252, and a fourth clamp 253, all located on the other side of the retaining ring assembly bracket 2. The two fourth guide rails 250 are arranged side by side along a second direction and extend along a first direction. A fourth slider that mates with the fourth guide rails 250 is mounted at the bottom of the second transfer seat 251. The second transfer seat 251 is driven by a second linear motor mounted on the spline push block assembly bracket 2 to move horizontally along the fourth guide rails 250. The spline push block chuck 252 is mounted on the second transfer seat 251 and is driven to rotate by a rotary motor mounted on the second transfer seat 251. The spline push block chuck 252 is a pneumatic four-jaw chuck. The fourth clamp 253 is located on the side of the fourth guide rail 250 away from the retaining ring assembly bracket 220. The fourth clamp 253 is driven by a fourth clamping cylinder 254 to move closer or further away from each other. The fourth clamping cylinder 254 is driven by a sixth horizontal cylinder 255 to move closer or further away from the retaining ring assembly bracket 220. The sixth horizontal cylinder 255 is driven by a sixth lifting cylinder 256 mounted on the spline push block assembly bracket 2 to lift and lower. The sixth lifting cylinder 256 is fixed on the spline push block assembly bracket 2 through a second cylinder mounting seat 257. Through the cooperation of the sixth horizontal cylinder 255 and the sixth lifting cylinder 256, the fourth clamp 253 is driven to perform horizontal and vertical movements.

[0059] All lifting cylinders and horizontal cylinders involved in the above embodiments are pneumatic cylinders.

[0060] Working principle: When assembling the spline push block, firstly, prepare the machined spline push block 101, clutch spring, wedge push block, and flattened wire retaining ring 102. The clutch spring and wedge push block are assembled manually in advance. The assembled clutch spring and wedge push block are conveyed by the wedge push block feeding conveyor belt 202. The spline push block 101 is also conveyed by the spline push block feeding conveyor belt 201. The flattened wire retaining ring 102 is manually placed and stacked on the retaining ring placement seat, thus beginning the assembly process.

[0061] First, the spline pusher block 101 is conveyed by the spline pusher block feeding conveyor belt 201 to the area below the gripping bracket 203. Then, the spline pusher block gripping seat 204 slides along the first guide rail 207 to the area above the spline pusher block feeding conveyor belt 201. The second lifting cylinder 205 drives the first gripping electromagnet to move downwards. At this time, the first gripping electromagnet is energized, and the spline pusher block 101 is gripped by magnetic attraction. After gripping, the second lifting cylinder 205 drives the first gripping electromagnet to move upwards, and then the spline pusher block gripping seat 204 slides along the first guide rail 207 to the area above the third guide rail 241. At this time, the first transfer seat 242 slides along the third guide rail 241 to the bottom of the spline push block gripping seat 204. The second lifting cylinder 205 drives the first gripping electromagnet to descend, placing the spline push block 101 gripped by the first gripping electromagnet into the pneumatic three-jaw chuck at the top of the first transfer seat 242. The pneumatic three-jaw chuck clamps the spline push block 101. At the same time, the first gripping electromagnet is de-energized, so that the first gripping electromagnet can be smoothly separated from the spline push block 101. After separation, the first gripping electromagnet moves to grip the next spline push block 101.

[0062] Then, the first transfer seat 242 drives the spline pusher 101 to move below the third clamp 243. The fifth lifting cylinder 247 drives the third clamp 243 downward until the two third clamps 243 move down to both sides of the spline pusher 101. Then, the third clamping cylinder 245 is activated, driving the two third clamps 243 to move closer to each other, thus clamping the spline pusher 101. At the same time, the pneumatic three-jaw chuck releases its grip on the spline pusher 101. After the third clamps 243 clamp, the fifth lifting cylinder 247 drives the third clamps 243 upward, causing the spline pusher 101 to move downward. 1. Separate from the pneumatic three-jaw chuck, ensuring that the height of the third clamp 243 is lower than the height of the retaining ring assembly platform 221. Then, the fifth horizontal cylinder 246 drives the third clamp 243 to move horizontally to below the retaining ring assembly platform 221 and above the spline push block placement seat 240. Then, the fifth lifting cylinder 247 drives the third clamp 243 to descend, placing the spline push block 101 in the groove of the spline push block placement seat 240. At the same time, the third clamp 243 releases its grip on the spline push block 101 and returns to its original position under the drive of the fifth horizontal cylinder 246.

[0063] Driven by the seventh horizontal cylinder, the retaining ring pusher 231 moves in advance, pushing a flattened steel wire retaining ring 102 into the opening 227. After the spline pusher 101 is placed in the groove of the spline pusher placement seat 240, the fourth lifting cylinder 222 drives the retaining ring assembly platform 221 to move down, so that the retaining ring assembly platform 221 approaches the spline pusher 101. After moving down to the correct position, the seventh lifting cylinder 233 drives the retaining ring pressing column 234 to move down, so that the retaining ring pressing column 234 passes through the opening 227 and pulls the flattened steel wire retaining ring 102 in the opening 227 down together. At this point, the flattened wire retaining ring 102 is fitted onto the outer wall of the positioning boss 236. As the flattened wire retaining ring 102 descends, due to the design of the opening 227, which is larger at the top and smaller at the bottom, the flattened wire retaining ring 102 will deform so that it can pass smoothly through the opening 227 and fall onto the spline push block 101 below. As the retaining ring pressing column 234 continues to descend, the flattened wire retaining ring 102 and the spline push block 101 are pressed together. After pressing, the retaining ring pressing column 234 moves upward and returns to its original position, and the retaining ring assembly platform 221 also moves upward and resets.

[0064] Driven by the sixth horizontal cylinder 255, the fourth clamp 253 extends below the retaining ring assembly platform 221 and grabs the spline push block 101 with the flattened steel wire retaining ring 102. After grabbing, it returns to its original position with the cooperation of the sixth lifting cylinder 256 and the sixth horizontal cylinder 255. At this time, the second transfer seat 251 moves to the bottom of the fourth clamp 253, and the fourth clamp 253 moves down to place the spline push block 101 with the flattened steel wire retaining ring 102 in the spline push block chuck 252, which clamps the spline push block 101.

[0065] The second transfer seat 251 slides along the fourth guide rail 250 to the bottom of the material gripping bracket 203. The second gripping electromagnet grabs the assembled clutch spring and wedge push block from the wedge push block feeding conveyor belt 202 in advance, and moves to the top of the second transfer seat 251 under the drive of the wedge push block gripping seat 210. After moving into position, the second gripping electromagnet moves downward under the drive of the third lifting cylinder 211, pressing the assembled clutch spring and wedge push block into the spline push block 101 equipped with the flattened steel wire retaining ring 102. At the same time as pressing, the spline push block chuck 252 rotates under the drive of the motor. This process achieves spinning, thus completing the assembly of the spline push block assembly. After assembly, the second transfer seat 251 retracts to its original position along the fourth guide rail 250, and the assembled spline push block assembly is removed manually. This achieves semi-automatic assembly of the spline push block assembly, reducing the number of manual assembly steps and significantly reducing manual labor. Small components such as the flattened wire retaining ring 102 are automatically assembled, while components such as the wedge push block and clutch spring, which cannot currently be automatically assembled, are pre-assembled manually, avoiding omissions that may occur during manual assembly and ensuring smooth assembly.
