Description

Technical Field

[0001] This invention relates to the field of clutch disc processing, and more particularly to a surface grooving machine for transmission system friction discs. Background Technology

[0002] The clutch disc, also known as the clutch friction plate, is a wear part in the motor vehicle's running system. Its main function is to transmit and disconnect power between the engine and the transmission, enabling the vehicle to start smoothly, shift gears, and prevent overload of the transmission system.

[0003] When machining clutch plates, both transverse and longitudinal grooving are required on their surface. Existing grooving equipment typically involves manually placing each clutch plate under the cutting blade for cutting. The cutting process begins with transverse grooving. After this, the clutch plate is manually repositioned and placed under the cutting blade for a second cut, completing the longitudinal grooving.

[0004] Existing clutch disc surface grooving machines mainly suffer from the following technical problems: 1. It can usually only meet the requirements of a single size and cannot meet the processing requirements of multi-size ring pieces, so its versatility is poor.

[0005] 2. Feeding of the annular sheet is usually done manually, with a low degree of automation.

[0006] 3. When using a robotic arm to handle ring-shaped pieces, it can only handle ring-shaped pieces of a single size and cannot be adapted to ring-shaped pieces of different sizes, resulting in poor versatility.

[0007] 4. When grooving the surface of the annular plate, it is impossible to continuously and automatically groove the transverse and longitudinal grooves. After machining the transverse groove, it is necessary to manually rotate and adjust the angle of the annular plate to cut the longitudinal groove. The automation level is low, the labor intensity is high, and the processing efficiency is low. Summary of the Invention

[0008] The purpose of this invention is to provide a surface grooving machine for transmission system friction plates, which effectively solves at least one technical problem existing in the prior art.

[0009] The technical solution adopted by this invention to solve its technical problem is: a surface grooving machine for transmission system friction plates, including a frame, with a discharge station, a feeding station, and a grooving station arranged sequentially from left to right at the front of the frame, and a conveying structure arranged at the rear of the frame for moving the workpiece between the discharge station, the feeding station, and the grooving station. The grooving station is equipped with a set of rotatable electromagnetic rotary chucks. The electromagnetic rotary chucks are used to place the workpiece to be processed and can drive the workpiece to be processed to rotate, so as to switch the cutting angle of the workpiece. The handling structure includes a linear slide module arranged along the X-axis. The slide block of the linear slide module is equipped with a lifting cylinder that can move with it. The piston part of the lifting cylinder is equipped with a handling robot that can be raised and lowered with it. The frame is located behind the transport structure and has a three-axis slide module. The three-axis slide module is equipped with a three-phase main spindle motor that can move along the three axes. The main spindle motor shaft is connected to a cutter shaft that rotates with it. The cutter is positioned along the Y-axis above the electromagnetic rotary chuck. The cutter shaft is equipped with a set of spaced-apart disc cutting blades that are compatible with the workpiece to be processed on the electromagnetic rotary chuck.

[0010] Furthermore, a feeding platform is provided at the feeding station of the machine frame, and a feeding support column is provided below the feeding platform. A manual three-jaw chuck is provided on the top of the feeding support column, and a rotary handle for driving the three jaws to move synchronously is provided on the outside of the manual three-jaw chuck. Each jaw of the feeding platform is provided with a strip-shaped track hole corresponding to each jaw of the three-jaw chuck. The manual three-jaw chuck is located below the feeding platform. A set of size adjustment and positioning holes is formed on the upper end face of each jaw along its length. A vertical feeding positioning column is provided above the feeding platform corresponding to each strip-shaped track hole. The bottom of the feeding positioning column passes through the strip-shaped track hole and is assembled into the size adjustment and positioning hole. The feeding positioning column can move with the jaw within the strip-shaped track hole. The top of the feeding positioning column is formed with a chamfered frustum.

[0011] Furthermore, the frame is provided with a grooving station slot at the grooving station, and a set of electromagnetic rotating circular suction cups are arranged at intervals from left to right in the grooving station slot; the frame is provided with a suction cup rotation drive mechanism corresponding to each electromagnetic rotating circular suction cup below the grooving station slot, and a dust suction port is opened on one side of the grooving station slot for connecting to the dust suction system.

[0012] Furthermore, the suction cup rotation drive mechanism can be a suction cup rotation cylinder. A fixed bracket is provided on the cylinder barrel of the suction cup rotation cylinder, and a hollow through-hole slip ring is provided on the fixed bracket. The hollow through-hole slip ring is sleeved on the output shaft of the rotation cylinder, and the circuit of the electromagnetic rotating circular suction cup is connected to the slip ring. A rotation damper is also provided on the output shaft of the suction cup rotation cylinder.

[0013] Furthermore, the electromagnetic rotary chuck can rotate 90° clockwise and 90° counterclockwise; two rotation limit bolts are set at 180° opposite each other on the outer side wall of the electromagnetic rotary chuck, and two buffer limit brackets are set in the slot of the grooving station corresponding to each electromagnetic rotary chuck. The two buffer limit brackets are respectively set with a first hydraulic buffer. The first hydraulic buffers are arranged at 90° orthogonal, and the first hydraulic buffers and the rotation limit bolts are matched one by one.

[0014] Furthermore, the handling robot is a three-jaw cylinder. Each jaw of the three-jaw cylinder has a detachable extension jaw arm at its bottom, which extends outward away from the center of the three-jaw cylinder. The extension jaw arm has a strip-shaped adjustment hole along its length, and each extension jaw arm has an extension jaw at its bottom. The strip-shaped adjustment hole has an adjustment bolt for fixing the extension jaw. The upper end face of the extension jaw and the bottom end face of the extension jaw arm are formed with meshing teeth that can mesh with each other. The bottom of the end of the extension jaw away from the center of the three-jaw cylinder has a gripping tooth. The bottom of the cylinder barrel of the three-jaw cylinder is equipped with a sensing bracket, and the sensing bracket is equipped with a proximity switch that matches the workpiece to be processed at the feeding station. The position of the proximity switch is adjustable to adapt to workpieces of different sizes.

[0015] Furthermore, the piston part of the lifting cylinder is equipped with a lifting fixing seat that can be raised and lowered with it. A set of detachable second hydraulic buffers are also arranged vertically at intervals on the lifting fixing seat. The second hydraulic buffers are located on the outside of the extended claw arm.

[0016] Furthermore, the piston part of the lifting cylinder is equipped with a rotating fixed seat that can be raised and lowered with it. The rotating fixed seat is equipped with a feeding rotary cylinder. The output shaft of the feeding rotary cylinder is equipped with a flipping fixed seat that can rotate 180° with it. The upper end face of the flipping fixed seat is equipped with a three-jaw cylinder with the claw opening facing upwards, and the lower end face is equipped with a three-jaw cylinder with the claw opening facing downwards. The two three-jaw cylinders are coaxially arranged and have the same model and specifications.

[0017] Furthermore, the cutter rotary motor housing is equipped with an outer cover that matches the cutter shaft. An air knife is installed on the outer wall of the outer cover facing the feeding station. The outer cover, air knife, and cutter shaft are located above the cutting station slot.

[0018] Furthermore, anti-collision posts are set at both ends of the linear slide module; the linear slide module is located between the two anti-collision posts, and corresponding position sensing switches are set at the locations of the unloading station, the loading station, and each electromagnetic rotating chuck; the unloading station is equipped with an unloading platform, and the unloading platform is equipped with an unloading temporary storage tank.

[0019] Compared with the prior art, the present invention has the following significant advantages: 1. By setting the discharge station to the left of the feed station and the discharge station to the rear of the grooving station, both the discharge and feed stations are located on the same side of the grooving machine, making operation simpler and avoiding the high cost of having a single operator running back and forth or having two people working at both ends.

[0020] 2. The three-axis slide module, the three-phase spindle motor, and the cutter axis work together to achieve three-axis position adjustment of the cutter axis, which can meet the needs of adjusting the cutter position under different conditions. Compared with the case where the cutter axis position is fixed, it can better meet the needs of high-precision machining.

[0021] 3. The electromagnetic rotating disk can rotate 90° after the transverse grooving is completed to perform longitudinal grooving. The electromagnetic rotating disk automatically achieves 90° reciprocating rotation through a rotation drive device, which can automatically coordinate and complete the continuous transverse and longitudinal grooving, improve production efficiency, and reduce labor intensity.

[0022] 4. The manual three-jaw chuck, rotary handle, strip track hole, size adjustment positioning hole, and vertically upward feeding positioning pin work together to allow manual adjustment of the opening degree of the jaws of the manual three-jaw chuck by rotating the handle, thereby adjusting the size of the workpiece placement area formed by the three positioning pins to meet the feeding requirements of workpieces of different sizes. Compared with existing fixed-size feeding and conveying devices, it has a wider range of applications and stronger versatility.

[0023] 5. A set of multiple electromagnetic rotary chucks can simultaneously process multiple workpieces, achieving uninterrupted and continuous processing. For example, after the workpiece on the first electromagnetic rotary chuck has been grooved, when grooving the workpiece on the second electromagnetic rotary chuck, the first electromagnetic rotary chuck can be rotated 90° using a chuck rotation cylinder. After the workpiece on the second electromagnetic rotary chuck has been grooved, the second electromagnetic rotary chuck can be rotated 90° using the chuck rotation cylinder, and then the cutting shaft can return to its initial position and start moving again to complete the second grooving. The entire action is continuous, effectively improving grooving efficiency.

[0024] 5. The rotating limit bolt and the first hydraulic buffer work together to limit and buffer the rotation of each electromagnetic rotating chuck at 90° forward and reverse, thus improving its service life.

[0025] 6. The second hydraulic buffer can play a buffering role during the falling process of the transport robot picking up and placing the film.

[0026] 7. The air knife effectively solves the problem of removing debris that falls onto the electromagnetic rotating chuck during the grooving process.

[0027] 8. The extended claw arm, strip-shaped adjustment hole, extended chuck, meshing tooth surface, and gripping tooth engagement allow for adjustment of the chuck inner diameter according to the size of different workpieces to meet the clamping and gripping requirements of different workpieces, thus expanding its application range.

[0028] 9. The rotating fixed base, the rotating cylinder, and the three-jaw cylinder with reverse-oriented claw openings on the upper and lower end faces of the rotating fixed base can simultaneously grip two workpieces to be processed, effectively improving the efficiency of loading and unloading.

[0029] 10. Anti-collision posts and position sensing switches can effectively control and monitor the position of the lifting cylinder, improving the accuracy of automated processing.

[0040] The specific structure of the three-axis slide module 5 can refer to existing technology, which includes three axial drive servo motors that drive the X, Y, and Z axes respectively. The specific selection can be made flexibly according to the needs, and it is not an innovation of this case, so it will not be described in further detail here.

[0041] A feeding platform 28 is provided at the feeding station of the frame 1. A feeding support column 10 is provided below the feeding platform 28. A manual three-jaw chuck 11 is provided on the top of the feeding support column 10.

The feeding positioning column 12 can move with the jaw within the strip-shaped track hole 30. The top of the feeding positioning column 12 is formed with a chamfered frustum. The annular workpiece to be processed is placed in the area formed by three feed positioning columns 12.

[0042] The manual three-jaw chuck structure is existing technology and is not an innovative part of this case. Therefore, it will not be described in detail here. Its structure can also be referred to as a three-jaw cylinder.

[0043] The frame 1 is located at the grooving station and is equipped with a grooving station slot. A set of electromagnetic rotating circular suction cups 2 are arranged at intervals from left to right in the grooving station slot. The frame 1 is located below the grooving station slot and is equipped with a suction cup rotation drive mechanism corresponding to each electromagnetic rotating circular suction cup 2. A dust suction port is opened on one side of the grooving station slot, which is used to connect to the dust suction system.

[0044] The suction cup rotation drive mechanism can be a suction cup rotation cylinder 13. A fixed bracket 14 is provided on the cylinder barrel of the suction cup rotation cylinder 13. A hollow through-hole slip ring 15 is provided on the fixed bracket 14. The hollow through-hole slip ring 15 is sleeved on the output shaft of the rotation cylinder. The circuit of the electromagnetic rotating circular suction cup 2 is connected to the slip ring. A rotation damper is also provided on the output shaft of the suction cup rotation cylinder 13.

[0045] The electromagnetic rotating chuck 2 can rotate 90° clockwise and 90° counterclockwise. Two rotation limit bolts are set at 180° opposite each other on the outer side wall of the electromagnetic rotating chuck 2. Two buffer limit brackets are set in the groove of the grooving station corresponding to each electromagnetic rotating chuck 2. The two buffer limit brackets are respectively set with a first hydraulic buffer. The first hydraulic buffers are arranged at 90° orthogonal. The first hydraulic buffers and the rotation limit bolts are matched one by one.

[0046] The handling robot is a three-jaw cylinder 16. Each jaw of the three-jaw cylinder 16 has a detachable extension jaw arm 17 at its bottom. The extension jaw arm 17 extends outward from the jaw center of the three-jaw cylinder 16. The extension jaw arm 17 has a strip-shaped adjustment hole along its length. Each extension jaw arm 17 has an extension jaw 18 at its bottom. The strip-shaped adjustment hole has an adjustment bolt for fixing the extension jaw 18. The upper end face of the extension jaw 18 and the bottom end face of the extension jaw arm 17 are formed with meshing tooth surfaces 19 that can mesh with each other. The bottom of the end of the extension jaw 18 away from the jaw center of the three-jaw cylinder 16 has a gripping tooth 20. The bottom of the cylinder barrel of the three-jaw cylinder 16 is provided with a sensing bracket. The sensing bracket is provided with a proximity switch that matches the workpiece to be processed at the feeding station. The position of the proximity switch is adjustable to adapt to workpieces of different sizes.

[0047] The piston part of the lifting cylinder 4 is provided with a lifting fixing seat 21 that can be raised and lowered with it. A set of detachable second hydraulic buffers 22 are also arranged vertically at intervals on the lifting fixing seat 21. The second hydraulic buffers 22 are located on the outside of the extension claw arm 17. The three-claw cylinder 16 is provided on the lifting fixing seat 21.

[0048] Unlike a handling robot that uses a single three-jaw cylinder 16, the piston of the lifting cylinder is equipped with a rotating fixed seat 23 that can move up and down with it. The rotating fixed seat 23 is equipped with a feeding rotary cylinder 26. The output shaft of the feeding rotary cylinder 26 is equipped with a flipping fixed seat 27 that can rotate 180° with it. The upper end face of the flipping fixed seat 27 is equipped with a three-jaw cylinder 16 with its jaws facing upwards, and the lower end face is equipped with a three-jaw cylinder 16 with its jaws facing downwards. The two three-jaw cylinders 16 are coaxially arranged and have the same model and specifications.

[0049] The housing of the rotary motor for the cutter is equipped with an outer cover 24 that is compatible with the cutter shaft 7. An air knife is installed on the outer wall of the outer cover 24 facing the feeding station. The outer cover 24, the air knife, and the cutter shaft 7 are located above the slot of the cutting station.

[0050] The linear slide module 3 is equipped with anti-collision posts at both ends; the linear slide module 3 is located between the two anti-collision posts, and corresponding position sensing switches are provided for the material discharge station, the material loading station, and the positions of each electromagnetic rotating chuck 2; the material discharge station is equipped with a material discharge platform 25, and the material discharge platform 25 is equipped with a material discharge temporary storage tank.

[0051] Based on the dimensions of the workpiece, the opening degree of the jaws of the manual three-jaw chuck 11 is manually adjusted by rotating the handle, and the size of the feeding placement area formed by the three feeding positioning pins 12 mounted on its jaws is adjusted to fit the dimensions of the workpiece. Simultaneously, the position of the extended jaw 18 relative to the extended jaw arm 17 needs to be adjusted according to the dimensions of the workpiece, adjusting the size of the area formed by the three gripping teeth 20 during gripping to meet the gripping requirements of the workpiece. The three-axis slide module 5 controls the main spindle three-phase motor 6 to drive the cutter shaft 7 to the set three-axis position.

[0052] When the linear slide module 3 is working, the lifting cylinder 4 moves to the feeding station, the handling robot moves down to the set position, the three-jaw cylinder 16 works, clamps a piece to be processed, then the lifting cylinder 4 moves up, the lifting cylinder continues to move along the linear slide module 3 to the grooving station, then the lifting cylinder moves down, the three-jaw cylinder 16 works, places the piece to be processed on an electromagnetic rotating chuck 2, controls the electromagnetic rotating chuck 2 to magnetically attract the piece to be processed, then the three-jaw cylinder 16 returns to the initial state, the lifting cylinder 4 moves up, the lifting cylinder continues to move along the linear slide module 3 to the feeding station, repeating the above work, placing the next piece to be processed on another electromagnetic rotating chuck 2.

[0053] The three-axis slide module 5 drives the spindle three-phase motor 6 to move horizontally from right to left. During this process, the transverse grooving of the workpiece on the right electromagnetic rotary chuck 2 is completed first. After completion, it quickly moves to the left to the second electromagnetic rotary chuck 2 to complete the transverse grooving of the workpiece on the second electromagnetic rotary chuck 2. During this process, the first electromagnetic rotary chuck 2 rotates through the chuck rotation cylinder 13. After rotating to the correct position, the workpiece on the second electromagnetic rotary chuck 2 completes the transverse grooving, and the second electromagnetic rotary chuck 2 rotates. During this process, the three-axis slide module 5 drives the spindle three-phase motor 6 to rise to the set position and then quickly moves to the right. Then, the above movement from right to left is repeated to complete the longitudinal grooving. After the grooving is completed, the linear slide module 3 controls the lifting cylinder to move to the corresponding position, controls the three-jaw cylinder 16 to descend and grab the finished part, and then the three-jaw cylinder 16 moves upward. The linear slide module controls the lifting cylinder to move to the discharge station, the lifting cylinder works, and after the three-jaw cylinder 16 descends to the position, the three-jaw cylinder 16 controls the jaws to open, and the finished part is put down and falls to the discharge platform 25.

[0054] When the piston part of the lifting cylinder is equipped with a rotating fixed seat 23 that can be raised and lowered with it, and a feeding rotary cylinder 26 is installed on the rotating fixed seat 23, and a flipping fixed seat 23 that can rotate 180° with it is installed on the output shaft of the feeding rotary cylinder 26, and a handling robot is installed on the upper and lower end faces of the rotating fixed seat 23 respectively, when feeding and discharging, the downward-facing three-jaw cylinder 16 works first. After the downward-facing three-jaw cylinder 16 completes the gripping, the feeding rotary cylinder 26 drives the rotating fixed seat 23 to flip 180°, flipping the originally upward-facing three-jaw cylinder 16 to face downward, controlling the cover three-jaw cylinder 16 to work and complete the gripping. After all are completed, the lifting cylinder 4 works.
