Description

TECHNICAL FIELD

[0001] The application relates to the technical field of automobile part manufacturing, in particular to a material overturning support matched with a mechanical arm. BACKGROUND

[0002] As a key part of the automobile driving system and the steering system, the automobile knuckle is the core guarantee of the stability and safety of automobile control. It is like the "joint" of the automobile, one end is connected with the wheel, and the other end is closely connected with the suspension system of the automobile. It not only bears various complex external forces such as vertical force, driving force, braking force and lateral force from the road, but also rotates flexibly when the vehicle turns, realizing accurate steering control.

[0003] The knuckle is composed of left and right parts and is processed through a flow line. During the mechanical arm transfer process, cutting fluid is left on the surface of the knuckle. If the cutting fluid is not cleaned in time, it will not only pollute the subsequent processing equipment, affect the normal operation and service life of the equipment, but also cause damage to the surface quality of the knuckle, leading to corrosion and rust, reducing the reliability and durability of the product. At the same time, the residual cutting fluid will also pollute the working environment when the knuckle is parked, increasing the cleaning cost and difficulty. The stability of the knuckle is poor when it is parked after being transferred between processes. Due to the particularity of its shape and structure, and the influence of external vibration factors, it is easy to shake or displace during parking, even causing safety accidents, affecting production efficiency and product quality. During the process of transferring the knuckle by the mechanical arm, there is a lack of effective in-place reminder. Due to the particularity of its shape and structure, the sensor may not detect whether the workpiece is in place, thereby affecting the subsequent action of the mechanical arm. SUMMARY

[0004] The device provides a material overturning support matched with a mechanical arm, and the specific implementation manner is as follows:

[0005] A material overturning support matched with a mechanical arm, comprising:

[0006] A mounting frame is provided with a top plate for placing the knuckle at the top of the mounting frame. The top plate is provided with a through hole at the center through hole of the knuckle. The pneumatic clamping jaws of the mechanical hand reversely clamp the knuckle from above and below of the through hole respectively during taking and placing of the knuckle.

[0007] A oil receiving disc is arranged below the through hole and is installed on the mounting frame.

[0008] A gasket and a limiting column are arranged on both sides of the through hole on the top plate. The limiting column is clamped into the vertical through hole on one side of the knuckle, and the gasket is used to support the other side of the knuckle. An optical sensor for detecting whether the knuckle is in place is installed on the top plate.

[0009] Preferably, the top plate is provided with two guide openings, and the gaskets and limiting columns on the two guide openings are arranged in a central symmetric manner.

[0010] Based on the above technical scheme, by setting a top plate with a guide opening, not only the production efficiency is greatly improved, but also the flexible and efficient asynchronous clamping and taking and placing operation of the manipulator on the upper and lower ends of the steering knuckle is realized, and the production environment is further optimized, so that the cutting fluid remaining on the steering knuckle can flow along the preset path to the oil pan, thereby realizing directional collection and recycling of the cutting fluid, and also realizing reverse taking of the steering knuckle by the manipulator after parking of the steering knuckle for subsequent turning processing of the steering knuckle.

[0011] By arranging gaskets and limiting columns on both sides of the guide opening, the limiting column fixes the steering knuckle in a two-point positioning manner, ensuring the stability and accuracy of the steering knuckle during machining, effectively avoiding machining errors caused by shaking or misalignment; on the other hand, the gasket is used to raise the steering knuckle to an ideal horizontal state, so that the manipulator can more accurately and smoothly complete the grabbing and placing of the steering knuckle, thereby significantly improving the success rate of secondary transportation and further consolidating the smoothness and efficiency of the production line.

[0012] Preferably, the photoelectric sensor is rotatably installed on the top plate through the C-shaped plate, and the connection between the bottom of the C-shaped plate and the top plate is provided with a waist-shaped hole.

[0013] Preferably, an arc-shaped vertical groove slidingly connected with the photoelectric sensor is formed in the vertical surface of the C-shaped plate, an unlocking member is extended at the back of the photoelectric sensor, and a fixed point and a sliding point exist on the side of the photoelectric sensor, the fixed point is rotatably connected to the C-shaped plate, and the sliding point is slidingly connected to the arc-shaped vertical groove of the C-shaped plate.

[0014] Based on the above technical scheme, by using the unlocking member and the locking assembly on the C-shaped plate, a photoelectric sensor that can rotate flexibly is successfully added, which not only significantly enhances the accuracy and reliability of the photoelectric sensor during detection of the steering knuckle, but also greatly improves the convenience and flexibility of angle adjustment of the photoelectric sensor, so that the operator can easily adjust the detection angle of the sensor as needed to adapt to the detection needs of steering knuckles of different specifications or types.

[0015] Preferably, the locking assembly further includes a T-shaped sleeve arranged outside the positioning rod in the cavity, the T-shaped sleeve is slidingly connected to the arc-shaped vertical groove on the side, and the outer diameter of the T-shaped sleeve is greater than the groove width of the arc-shaped vertical groove.

[0016] Preferably, a wedge-shaped block is slidingly arranged in the cavity along the length direction of the positioning rod, the wedge-shaped block and the T-shaped sleeve are integrated, and a spring is arranged between the back of the wedge-shaped block and the cavity.

[0017] Preferably, the unlocking component includes a sleeve rod and a rotating rod that are threaded together, and the end of the rotating rod is provided with a pressure joint that is inserted into the cavity, with the pressure joint facing the inclined end of the wedge block.

[0018] Based on the above technical solution, the unlocking component is integrated into the internal structure of the sleeve, which greatly enhances the convenience of operation. By simply rotating the rotating rod, the angle locking or unlocking state of the photoelectric sensor can be easily switched, and the tilt angle of the sensor can be freely adjusted under the unlocking condition to meet the detection requirements of the steering knuckle protrusion.

[0019] Preferably, the bottom of the mounting bracket is provided with a height adjustment pad.

[0020] In summary, this application includes the following beneficial technical effects:

[0021] 1. By setting a top plate with a guide port, this utility model not only enables the robot arm to asynchronously clamp and pick up the upper and lower ends of the steering knuckle, but also enables the directional collection of cutting fluid on the steering knuckle onto the oil receiving pan;

[0022] 2. This utility model improves the accuracy of the photoelectric sensor in detecting the steering knuckle by adding a rotatable photoelectric sensor at the C-shaped plate using an unlocking component and a locking assembly, and also improves the convenience of adjusting the angle of the photoelectric sensor.

[0023] 3. This utility model has a simple structure. By setting shims and limiting posts on both sides of the guide port, the steering knuckle is positioned at two points using the limiting posts, and the steering knuckle is raised by the shims to make it horizontal, which further improves the success rate of the subsequent secondary transfer of the steering knuckle by the robot arm.

[0036] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0037] This application discloses a material flipping support for a robotic arm.

[0038] Example 1

[0039] Reference Figures 1 to 3This embodiment discloses a material flipping support for a robotic arm, including a mounting frame 12. The top of the mounting frame 12 is provided with a top plate 2 for placing a steering knuckle 10. The top plate 2 has a guide port 201 at the central through hole 1002 of the steering knuckle 10. The pneumatic gripper 14 of the robotic arm 13 grips the steering knuckle 10 in opposite directions above and below the guide port 201. An oil receiving tray 11 is provided below the guide port 201 and is mounted on the mounting frame 12. Gaskets 4 and limiting posts 5 are respectively provided on both sides of the guide port 201 on the top plate 2. The limiting post 5 is inserted into the vertical through hole 1001 on one side of the steering knuckle 10. The gasket 4 is used to support the other side of the steering knuckle 10. The top plate 2 is equipped with a photoelectric sensor 3 for detecting whether the steering knuckle 10 is in position. In this structure, the top plate 2 is provided with two guide ports 201, and the gasket 4 and the limiting post 5 on the two guide ports 201 are arranged in a centrally symmetrical manner. The bottom of the mounting bracket 12 is threaded with an adjustment pad 9. The cutting fluid on the steering knuckle 10 is generated in the process before the transfer by the robot arm 13. The cutting fluid is in a small amount of adhering state. The oil pan 11 can be replaced periodically.

[0040] Example 2

[0041] Reference Figures 1 to 6 This embodiment discloses a material flipping bracket for a robotic arm, which also includes a locking component 8. The photoelectric sensor 3 is rotatably mounted on the top plate 2 via a C-shaped plate 6. The bottom of the C-shaped plate 6 is bolted to the top plate 2 and a waist-shaped hole 602 is provided. An arc-shaped vertical groove 601 is provided on the vertical surface of the C-shaped plate 6 to slide and connect with the photoelectric sensor 3. An unlocking component 7 is provided on the back of the photoelectric sensor 3. A cavity 1 is provided at the bottom of the photoelectric sensor 3, and a positioning rod 101 extends outward from the cavity 1.

[0042] The locking assembly 8 includes a T-shaped sleeve 802 sleeved on the outside of the positioning rod 101. The T-shaped sleeve 802 is slidably connected to the arc-shaped vertical groove 601 on its periphery, and its outer diameter is larger than the groove width of the arc-shaped vertical groove 601. A wedge block 801 is slidably provided in the cavity 1 along the length direction of the positioning rod 101. The wedge block 801 and the T-shaped sleeve 802 are integrated, and a spring 803 is provided between the back of the wedge block 801 and the cavity 1. In this structure, the unlocking component 7 includes a sleeve rod 701 and a rotating rod 702 threaded together. The end of the rotating rod 702 is provided with a pressure joint 703 that penetrates into the cavity 1, and the pressure joint 703 faces the inclined end of the wedge block 801.

[0043] The specific implementation process is as follows: The pneumatic gripper 14 of the robot arm 13 is a conventional variable diameter structure. The pneumatic gripper 14 clamps the central through hole 1002 from the top of the steering knuckle 10. The robot arm 13 transfers the steering knuckle 10 to the guide port 201. The vertical through hole 1001 of the steering knuckle 10 is inserted into the limiting post 5, and the other side of the steering knuckle 10 abuts against the gasket 4. The photoelectric sensor 3 is triggered to respond, and the pneumatic gripper 14 of the robot arm 13 clamps the central through hole 1002 from the bottom of the steering knuckle 10 for the second time. After the steering knuckle 10 is transported in the opposite direction, the robot arm 13 is equivalent to gripping the steering knuckle 10 in the opposite direction and sending the bottom surface of the steering knuckle 10 back to the previous process, thus realizing the double-sided processing of the steering knuckle 10 in the subsequent process.

[0044] After adjusting the tilt angle of the photoelectric sensor 3, the rotating rod 702 is rotated relative to the sleeve rod 701, causing the pressure joint 703 to extend into the cavity 1 and act on the wedge block 801; the wedge block 801 drives the T-shaped sleeve 802 to move together, and the outer end of the T-shaped sleeve 802 presses against the arc-shaped vertical groove 601, so that the photoelectric sensor 3 is locked on the C-shaped plate 6; when adjusting the tilt angle of the photoelectric sensor 3, the rotating rod 702 is reversed to retract the pressure joint 703, and the T-shaped sleeve 802 and the wedge block 801 are reset under the action of the spring 803, and the pressing force between the T-shaped sleeve 802 and the C-shaped plate 6 is eliminated.

[0045] Many other changes and modifications can be made without departing from the concept and scope of this utility model. It should be understood that this utility model is not limited to the specific embodiments, and the scope of this utility model is defined by the appended claims.
