Description

Technical Field

[0001] This invention belongs to the field of robotics technology, specifically relating to a robotic aluminum alloy steering knuckle clamp. Background Technology

[0002] Currently, many steps in my country's steering knuckle manufacturing process are performed manually, resulting in high labor intensity and risks for workers, inconsistent product quality, and high energy consumption. Furthermore, the environmental problems caused by smoke, harmful gases, noise, and vibration pose serious threats to the physical and mental health of employees. Given the harsh working environment and high labor intensity in production workshops, pursuing and achieving automated production is an urgent need for every enterprise. The application of industrial robots provides a key to solving these problems. The development and application of fully automated robotic production lines offer a leapfrog development opportunity in improving product consistency, liberating labor, saving labor costs, ensuring safe production, increasing production efficiency, and enhancing the modernization level of enterprise production.

[0003] Steering knuckles are a key component of automotive steering axles. Their production has been initially mechanized. However, in terms of gripping steering knuckles, the robotic clamps on automated production lines exhibit issues such as unstable gripping and slippage, which directly affect the automation process and, consequently, production efficiency. Furthermore, the rigid contact between the clamps and the steering knuckles can significantly damage the forgings, thus impacting product quality. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a robot aluminum alloy steering knuckle clamp.

[0005] The technical solution is as follows: A robot aluminum alloy steering knuckle clamp, the key features of which are: a mounting base (1), a connecting flange (2) mounted on one side of the mounting base (1), and a left clamping arm (3) and a right clamping arm (4) mounted on the other side. The left clamping arm (3) and the right clamping arm (4) are arranged side by side. A telescopic mechanism is installed on the connecting flange (2) between the left clamping arm (3) and the right clamping arm (4). Under the action of the telescopic mechanism, the left clamping arm (3) and the right clamping arm (4) can retract or open. Flexible clamps are fixed on opposite sides of the left clamping arm (3) and the right clamping arm (4). With the above structure, the robot aluminum alloy steering knuckle clamp is installed on the robot through the connecting flange. Due to the use of flexible clamps, damage to the aluminum alloy steering knuckle can be avoided, thus improving the quality of the product.

[0006] Preferably, the mounting base (1) includes a mounting plate (1a) for fixing the connecting flange (2) and a left side plate (1b) and a right side plate (1c) respectively fixed at the left and right ends of the mounting plate (1a);

[0007] The telescopic mechanism includes a left double-acting cylinder (5) installed near the left side plate (1b) and a right double-acting cylinder (6) installed near the right side plate (1c). A guide rod (7) is installed between the left side plate (1b) and the right side plate (1c). The cylinder bodies of the left double-acting cylinder (5) and the right double-acting cylinder (6) are both supported on the guide rod (7) and can move along the guide rod (7). The piston rod of the left double-acting cylinder (5) passes through the left side plate (1b) and is fixed to the left side plate (1b). The piston rod of the right double-acting cylinder (6) passes through the right side plate (1c) and is fixed to the right side plate (1c).

[0008] Left clamping arm seat (8) and right clamping arm seat (9) are fixed on the outer side walls of the cylinder bodies of the left double-acting cylinder (5) and the right double-acting cylinder (6), respectively. The inner ends of the left clamping arm (3) and the right clamping arm (4) are fixed on the left clamping arm seat (8) and the right clamping arm seat (9), respectively.

[0009] Using the above structure, clamping is achieved through a left double-acting cylinder and a right double-acting cylinder. The actions of the left double-acting cylinder and the right double-acting cylinder can be controlled separately to achieve precise clamping.

[0010] Preferably, a support plate (10) is installed between the left double-acting cylinder (5) and the right double-acting cylinder (6). The support plate (10) is fixed to the middle of the mounting plate (1a) and to the guide rod (7). A connecting plate (11) is fixed on the support plate (10), and a locking cylinder (12) is fixed on the connecting plate (11). The cylinder body of the locking cylinder (12) is fixed to the connecting plate (11), and the outer end of the piston rod of the locking cylinder (12) is connected to a fixing block (13) fixed on the cylinder body of the right double-acting cylinder (6). By using a locking cylinder, the left and right clamping arms can be locked after clamping, thus making the clamping more reliable.

[0011] Preferably, both the left clamping arm (3) and the right clamping arm (4) are provided with flow channels (14) along their length. The inlet of the flow channel (14) is connected to an air inlet pipe (16) through an L-shaped quick-connect threaded joint (15). An asbestos sheath (17) is provided outside the air inlet pipe (16). The function of the flow channel is to: introduce cold air or cold liquid when the temperature is too high, which can protect the left and right clamping arms; and introduce hot air or hot liquid when the temperature is low, which can reduce the heat loss during workpiece processing and thus improve the quality of the workpiece. The asbestos sheath can effectively protect the air inlet pipe.

[0012] Preferably, the flexible clamp includes two narrow clamps (18) and a wide clamp (19) located between the narrow clamps (18). Both the narrow clamps (18) and the wide clamp (19) can be moved and adjusted on the left clamping arm (3) or the right clamping arm (4). If the clamps can be adjusted according to the model of the steering knuckle, the clamping will be more accurate. Of course, different clamps can also be replaced according to different products.

[0013] Preferably, the narrow clamp (18) includes a fixing plate (18a), a narrow clamping block (18b), and a spring (18c). A first mounting post (18d) is fixed on the fixing plate (18a), and a second mounting post (18e) is provided on the narrow clamping block (18b). One end of the spring (18c) is fixedly sleeved on the first mounting post (18d), and the other end is fixedly sleeved on the second mounting post (18e). With this structure, even if there is a deviation during clamping, the presence of the spring can achieve guidance, thereby ensuring precise clamping.

[0014] Preferably, the wide clamp (19) includes a connecting seat (19a), one side of which is fixed to the left clamping arm (3) or the right clamping arm (4), and the other side has at least two large arc-shaped mounting slots (19b). A large arc-shaped floating block (19c) adapted to the large arc-shaped mounting slot (19b) is installed in the large arc-shaped mounting slot (19b). The large arc-shaped floating block (19c) is installed between the clamping plates (19g) fixed on the upper and lower sides of the connecting seat (19a) via a rotating shaft (19d).

[0015] The large arc-shaped floating block (19c) has at least two small arc-shaped mounting slots (19e) on the side away from the large arc-shaped mounting slot (19b). A small arc-shaped floating block (19f) adapted to the small arc-shaped mounting slot (19e) is installed within each small arc-shaped mounting slot (19e). The small arc-shaped floating block (19f) is mounted between the clamping plates (19g) fixed to the upper and lower sides of the connecting seat (19a) via a rotating shaft (19d). The wide clamp is used to clamp wider areas, while the presence of various floating blocks avoids rigid collision contact, effectively improving the quality of the aluminum alloy steering knuckle.

[0016] Compared with the prior art, the beneficial effects of the present invention are: more precise and stable clamping during the processing of aluminum alloy steering knuckles, avoiding phenomena such as clamping slippage, and improving production efficiency and product quality.
