Description

Technical Field

[0001] This invention relates to the field of automotive CV joint processing technology, and in particular to an automotive CV joint clamping and transfer mechanism and a handling robot. Background Technology

[0002] The CV joint is a crucial component of a car's transmission system. Its function is to transmit engine power from the transmission to the two front wheels, propelling the vehicle. Also known as a constant velocity joint (CV joint), the CV joint is manufactured using precision forging because it needs to transmit heavy driving torque, bears heavy loads, requires high transmission precision, and is a vital safety component in automobiles.

[0003] The shortcomings of existing technology are that, during the machining of automotive CV joint parts on a lathe, traditional pneumatic clamps are prone to excessive clamping force, which can cause workpiece deformation or clamp head deformation, or insufficient clamping force, which can cause workpiece movement, resulting in tilting or sliding during handling. Summary of the Invention

[0004] The purpose of this invention is to provide a clamping and transferring mechanism and a handling robot for automotive CV joint parts. The clamping arm moves through a pressing component, and the clamping arm squeezes and clamps the inner wall of the CV joint part. A limiting component inside the clamping arm limits the movement of the clamping arm and the contact component, maintaining the stability of the CV joint part clamped by the clamping arm. The self-adaptive contact and extendable clamping arm achieve perfect fit to irregular curved surfaces. Furthermore, the braking gear set in the contact component enables dynamic adjustment and locking of the contact pressure, ensuring that the workpiece does not tilt or slide during the handling process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A clamping and transferring mechanism and a handling robot for automotive CV joints include a robotic arm with a rotating plate at one end. A clamping assembly is symmetrically arranged at one end of the rotating plate, and one end of the clamping assembly clamps the CV joint. The clamping assembly includes a fixed sleeve with a pressing member slidably disposed within it. The pressing member is drively connected to a clamping arm, and a limiting member is provided within the clamping arm to limit its position. When the robotic arm drives the rotating plate to move, the clamping arm extends into the CV joint and is pressed against the pressing member by the CV joint. The pressing member, under force, causes the clamping arm to extend and is limited by the limiting member, thus clamping and securing the CV joint. As a further description of the above technical solution: A sliding rod is fixedly connected inside the fixed sleeve. A fixing ring is fixedly connected to one end of the sliding rod away from the fixed sleeve. A clamping arm is slidably connected to one end of the sliding rod, and a groove is opened at one end of the clamping arm to match the sliding rod.

[0006] As a further description of the above technical solution: One end of the clamping arm is fixedly connected to a locking block, and the end of the clamping arm away from the locking block is provided with an abutment.

[0007] As a further description of the above technical solution: One end of the clamping arm is provided with a guide groove, and a limiting shaft is provided in the guide groove. Pressure rings are fixed to both ends of the limiting shaft. A connecting strip is fixed to one end of the pressure ring, and a movable ring is fixed to one end of the connecting strip. The movable ring is slidably disposed in the fixed sleeve.

[0008] As a further description of the above technical solution: One end of the movable ring is fixedly connected to a support spring, and the support spring is fixedly connected to the rotating plate.

[0009] As a further description of the above technical solution: The abutment includes a rectangular frame, a slide bar slidably connected inside the rectangular frame, a contact fixed to the top of the slide bar, a return spring fixed to the bottom of the slide bar, and one end of the return spring fixed to the rectangular frame.

[0010] As a further description of the above technical solution: A connecting shaft is movably provided within the rectangular frame. Brake gears are symmetrically fixed at both ends of the connecting shaft. A gear block is provided between the two brake gears. A rack rod is meshed at one end of the gear block, and the rack rod is fixed to the slide bar.

[0011] As a further description of the above technical solution: An air pump is fixed to one end of the rotating plate, and a straight rod is provided at one end of the air pump. The straight rod passes through the rotating plate and is fixed to a limit block. A connecting rod is fixed to one end of the limit block, and a push block is fixed to one end of the connecting rod. A connecting rod is provided at one end of the push block.

[0012] As a further description of the above technical solution: One end of the connecting rod is connected to a support rod, and one end of the support rod is provided with a brake bar, which is movably mounted on the clamping arm.

[0013] A handling robot is realized through the aforementioned ball cage clamping and transfer mechanism.

[0014] This invention provides a clamping and transferring mechanism and a handling robot for automotive CV joint components, which have the following advantages: In this invention, the pressing component drives the movement of the clamping arm, which presses and clamps the inner wall of the ball cage component. The limiting component inside the clamping arm limits the movement of the clamping arm and the contact component, maintaining the stability of the ball cage component held by the clamping arm. This achieves perfect fit between the adaptive contact and the extendable clamping arm on irregular curved surfaces. Furthermore, the braking gear set in the contact component dynamically adjusts and locks the contact pressure, ensuring that the workpiece does not tilt or slide during the handling process.

Detailed Implementation

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] Reference Figure 1-9A clamping and transferring mechanism and a handling robot for automotive CV joints include a robotic arm 1 with a rotating plate 2 at one end; a clamping assembly 3 is symmetrically arranged at one end of the rotating plate 2, and the clamping assembly 3 clamps a CV joint 4 at one end; the clamping assembly 3 includes a fixed sleeve 31, a pressing member 32 is slidably arranged inside the fixed sleeve 31, the pressing member 32 is drivenly connected to a clamping arm 33, and a limiting member 34 is provided inside the clamping arm 33, which limits the clamping arm 33; when the robotic arm 1 drives the rotating plate 2 to move, the clamping arm 33 extends into the CV joint 4 and the CV joint 4 presses the pressing member 32, the pressing member 32 is forced to drive the clamping arm 33 to extend and is limited by the limiting member 34, thereby realizing that the clamping arm 33 clamps and secures the CV joint 4.

[0019] Specifically, the robotic arm 1 drives the rotating plate 2 to rotate. The clamping components 3 are symmetrically fixed to one end of the rotating plate 2. The rotation of the rotating plate 2 drives the two clamping components 3 to change position. The fixed sleeve 31 located in the clamping component 3 is fixed to the rotating plate 2. The clamping arm 33 is movably connected in a cross shape inside the fixed sleeve 31. When the pressing member 32 outside the clamping arm 33 presses on the ball cage 4, the pressing member 32 is subjected to the pressing force and moves towards the fixed sleeve 31. At the same time, the pressing member 32 drives the clamping arm 33 to move, so that the clamping arm 33 extends outward in a cross shape, realizing the clamping arm 33 to press and clamp the inner wall of the ball cage 4, which facilitates the efficient handling of the ball cage 4 waiting to be processed. The limiting member 34 set inside the clamping arm 33 limits the movement of the clamping arm 33, maintains the stability of the ball cage 4 clamped by the clamping arm 33, and avoids the phenomenon of the ball cage 4 tilting or sliding.

[0020] A sliding rod 311 is fixedly connected inside the fixed sleeve 31. A fixed ring 312 is fixedly connected to the end of the sliding rod 311 away from the fixed sleeve 31. A clamping arm 33 is slidably connected to one end of the sliding rod 311, and a groove 3301 at one end of the clamping arm 33 is adapted to the sliding rod 311. A locking block 334 is fixedly connected to one end of the clamping arm 33, and an abutment 331 is provided at the end of the clamping arm 33 away from the locking block 334. A guide groove 333 is provided at one end of the clamping arm 33, and a limiting shaft 322 is provided in the guide groove 333. Pressure rings 321 are fixedly connected to both ends of the limiting shaft 322. A connecting strip 323 is fixedly connected to one end of the pressure ring 321, and a movable ring 324 is fixedly connected to one end of the connecting strip 323. The movable ring 324 is slidably disposed inside the fixed sleeve 31. 4. A support spring 325 is fixedly connected to one end of the rotating plate 2; the contact member 331 includes a rectangular frame 3314, a slide bar 3312 is slidably connected inside the rectangular frame 3314, a contact 3311 is fixedly connected to the top of the slide bar 3312, a return spring 3318 is fixedly connected to the bottom of the slide bar 3312, and one end of the return spring 3318 is fixedly connected to the rectangular frame 3314; a connecting shaft 3315 is movably provided inside the rectangular frame 3314, brake gears 3317 are symmetrically fixedly connected to both ends of the connecting shaft 3315, a gear block 3316 is provided between the two brake gears 3317, a rack rod 3313 is meshed at one end of the gear block 3316, and the rack rod 3313 is fixedly connected to the slide bar 3312; Specifically, the fixing sleeve 31 has a cylindrical barrel structure. The fixing ring 312 inside the fixing sleeve 31 is fixed to the fixing sleeve 31 via a slide rod 311. The slide rods 311 to which the fixing ring 312 is fixed are arranged in a cross shape. The clamping arm 33 slidably connected to the slide rod 311 moves towards the fixing sleeve 31 by pressing against the ball cage 4 through the pressure ring 321. The connecting shaft 3315 fixed to the pressure ring 321 drives the clamping arm 33 to move on the slide rod 311. The clamping arm 33 extends or converges on the slide rod 311 through the guide groove 333. When the clamping arm 33 extends into the inner cavity of the ball cage 4, the pressure ring 321 presses against the end of the ball cage 4. The pressure ring 321 is squeezed and drives the clamping arm 33 along the slide rod 311. When the clamping arm 33 extends, the contact member 331 at one end abuts against the inner wall of the ball cage 4. The contact 3311 in the contact member 331 is squeezed against the inner wall of the ball cage 4. With the further extension of the clamping arm 33, the slide bar 3312 fixed to the contact 3311 moves in a direction along the rectangular frame 3314 and drives the fixed return spring 3318 to store force. The rack fixed to the slide bar 3312 drives the meshing gear block 3316 to rotate, so that the gear block 3316 rotates through the fixed brake gear 3317. By locking the brake gear 3317, the contact 3311 can be more evenly stressed against the inner wall of the ball cage 4, and the stability of the contact position between the contact 3311 and the inner cavity of the ball cage 4 can be improved. The rectangular frame 3314 is connected to the clamping arm 33 via the connecting shaft 3315. When the clamping arm 33 extends into the ball cage 4, the rectangular frame 3314 and the clamping arm 33 form an inclined angle to facilitate the insertion of the contact 3311 into the inner cavity of the ball cage 4. The return spring 3318 fixed to the rectangular frame 3314 presses the contact 3311 fixed to the slide bar 3312 against the groove in the inner wall of the ball cage 4, so that the ball cage 4 is more stable during transportation and avoids uneven force on the clamping arm 33 caused by the machining groove in the inner cavity of the ball cage 4.

[0021] An air pump 35 is fixedly connected to one end of the rotating plate 2. A straight rod 341 is provided at one end of the air pump 35. The straight rod 341 passes through the rotating plate 2 and is fixedly connected to a limit block 342. A connecting rod 343 is fixedly connected to one end of the limit block 342. A push block 344 is fixedly connected to one end of the connecting rod 343. A connecting rod 345 is provided at one end of the push block 344. A support rod 3321 is connected to one end of the connecting rod 345. A brake strip 3322 is provided at one end of the support rod 3321, and the brake strip 3322 is movably mounted on the clamping arm 33. Specifically, the air pump 35 fixed to the rotating plate 2 drives the straight rod 341 to extend and retract. The limiting block 342 fixed to the straight rod 341 moves to the locking block 334 fixed to the clamping arm 33, limiting the clamping arm 33 driven by the pressure ring 321. The limiting block 342 is fixed to the push block 344 via the connecting rod 343, on which connecting rods 345 are arranged in a cross shape. One end of the connecting rod 345 is slidably connected to the push block 344. When the clamping arm 33 extends, the connecting rod 345... Sliding along the push block 344, when the push block 344 moves in a direction, the push block 344 abuts against the connecting rod 345 and drives the push rod 332 to move laterally through the connecting rod 345. The support rod 3321 fixed to the push rod 332 drives the brake strip 3322 to rotate. The rotated brake strip 3322 abuts against the brake gear 3317 to limit its movement, thereby limiting the clamping arm 33 and the contact 3311 and maintaining the stability of the force on the clamping arm 33 and the contact 3311.

[0022] Working Principle: The overall workflow involves the robotic arm 1 driving the rotating plate 2 to move, bringing the symmetrically arranged clamping components 3 closer to the ball cage component 4. When the clamping arm 33 extends into the ball cage component 4, the port of the ball cage component 4 presses against the pressing member 32, causing it to slide towards the fixing sleeve 31. The pressing member 32, through a transmission structure, drives the clamping arm 33 to extend outward along the slide rod 311 until the contact member 331 tightly adheres to the inner wall of the ball cage component 4. Subsequently, the limiting member 34 is activated, locking the position of the clamping arm 33 to achieve stable clamping of the ball cage component 4. After completing the handling or processing task, the air pump 35 drives the unlocking mechanism to release the clamping arm 33, and under the action of the support spring 325, all components return to their initial state.

[0023] Robotic arm 1 and rotating plate 2; robotic arm 1 serves as the power output end and can achieve multi-dimensional movement; rotating plate 2 is fixed to the end of robotic arm 1 and achieves the switching of the work positions of the two clamping components 3 through rotation.

[0024] Clamping assembly 3: Composed of a fixed sleeve 31, a pressing member 32, a clamping arm 33, and a limiting member 34. The fixed sleeve 31 has a cylindrical barrel structure, and a fixed ring 312 is connected inside by a cross-shaped sliding rod 311; the clamping arm 33 slides with the sliding rod 311 through a sliding groove 3301, and can extend or converge radially; the pressing member 32 is composed of a pressure ring 321, a connecting strip 323, and a movable ring 324, and the movable ring 324 is connected to a support spring 325 to provide reset power.

[0025] The contact element, installed at the end of the clamping arm 33, includes a rectangular frame 3314, a slide bar 3312, a contact 3311, and a braking gear set. The contact 3311 maintains pre-pressure through a return spring 3318 and adapts to the groove profile after contacting the inner wall of the ball cage 4. The braking gear set is linked to the slide bar 3312 through a rack rod 3313 to achieve dynamic locking of the contact pressure.

[0026] Clamping and locking mechanism: Adaptive clamping process; when the clamping arm 33 extends into the ball cage 4, the pressure ring 321 first contacts the port and moves towards the fixed sleeve 31 under force. Through the cooperation of the guide groove 333 and the limiting shaft 322, the clamping arm 33 unfolds outward along the slide bar 311 until the contact 3311 contacts the inner wall. As the pressing member 32 continues to move, the contact 3311 presses the slide bar 3312 to compress the return spring 3318, while the rack bar 3313 drives the gear block 3316 to rotate, so that the brake gear 3317 is in the locking state.

[0027] A multi-stage locking system is employed. An air pump 35 drives a straight rod 341 to push a limiting block 342 into the slot of a locking block 334, achieving primary position locking of the clamping arm 33. Simultaneously, a push block 344 pushes a pull rod 3321 via a connecting rod 345, causing the brake strip 3322 to rotate and engage with the teeth of the brake gear 3317, completing secondary pressure locking. This dual locking mechanism ensures that the ball cage component 4 maintains a stable posture during handling, even under external impact, preventing tilting or slippage.
