Description

Technical Field

[0001] The invention belongs to the technical field of robots, and in particular relates to a robot aluminum alloy steering knuckle clamp. Background Art

[0002] At present, many steps in the steering knuckle production process in my country are completed by manual operation, which is labor-intensive and dangerous, with unstable product quality and high energy consumption. At the same time, environmental problems such as smoke, harmful gases, noise and vibration also pose a serious threat to the physical and mental health of employees. The working environment in the production workshop is harsh and the labor intensity is high. The pursuit and realization of automated production is an urgent need for every enterprise. The application of industrial robots provides enterprises with a key to solve the problem. The development and application of robot fully automatic production lines provide opportunities for leapfrog development in improving product consistency, liberating labor, saving labor costs, ensuring safe production, improving production efficiency and improving the level of modern production of enterprises.

[0003] The steering knuckle is a key component of the automobile steering axle. Its production has been initially mechanized. However, in terms of clamping the steering knuckle, the robot clamps in the automated production line have problems such as unstable clamping and sliding clamping, which directly affect the automation process and thus the production efficiency. At the same time, the rigid contact between the clamp and the steering knuckle will greatly damage the forging, thus affecting the product quality. Summary of the invention

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

[0005] The technical scheme is as follows: A robot aluminum alloy steering knuckle clamp, the main points of which are: comprising a mounting seat (1), a connecting flange (2) installed on one side of the mounting seat (1), and a left clamp arm (3) and a right clamp arm (4) installed on the other side, the left clamp arm (3) and the right clamp arm (4) are arranged side by side, a telescopic mechanism is installed on the connecting flange (2) between the left clamp arm (3) and the right clamp arm (4), under the action of the telescopic mechanism, the left clamp arm (3) and the right clamp arm (4) can be contracted or opened; flexible clamps are fixed on the opposite sides of the left clamp arm (3) and the right clamp 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 the flexible clamp, damage to the aluminum alloy steering knuckle can be avoided, thereby improving the quality of the product.

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

[0007] The telescopic mechanism comprises 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);

[0009] With the above structure, clamping is achieved through the left double-acting cylinder and the 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 part of the mounting plate (1a) and is fixed to the guide rod (7), a connecting plate (11) is fixed to the support plate (10), a locking cylinder (12) is fixed to 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 to the cylinder body of the right double-acting cylinder (6). The use of the locking cylinder can realize the locking of the left clamping arm and the right clamping arm after clamping, so that the clamping is more reliable.

[0011] Preferably, a flow channel (14) is provided inside the left clamp arm (3) and the right clamp arm (4) along the length direction, the inlet of the flow channel (14) is connected to an air inlet pipe (16) through an L-shaped quick-insert threaded joint (15), and an asbestos sheath (17) is provided outside the air inlet pipe (16).
