Description

Technical Field

[0001] This utility model relates to the field of automotive steering knuckle technology, specifically to an automotive steering knuckle press-fitting device. Background Technology

[0002] The steering knuckle is one of the main components of a car's steering axle. Its function is to transmit and bear the load from the front of the car, support and drive the front wheels to rotate around the kingpin to steer the car, ensuring stable driving and sensitive transmission of driving direction. In short, it bears the load from the front of the car and supports and drives the front wheels to rotate around the kingpin to steer the car. To reduce wear, a bronze bushing is usually pressed into the steering knuckle pin hole. The bushing reduces friction, and this process usually requires a press-fitting device.

[0003] For example, Chinese utility model patent CN221538795 U discloses a pressing device for a rear steering knuckle of an automobile, including a worktable. The upper surface of the worktable has a groove, and one side of the groove has a mounting groove. An adjustment structure is provided inside the groove. The adjustment structure includes a drive motor, a drive gear, a driven gear, a ball screw, a bearing, and a slider. The mounting groove is provided inside the bearing, and a ball screw is provided at the axis of the bearing. The ball screw is rotatably connected inside the groove. One end of the ball screw extends to the outside of the worktable and is equipped with a driven gear. A slider is slidably connected to the outer surface of the ball screw. The output end of the drive motor is equipped with a drive gear, and the drive gear meshes with the driven gear. The beneficial effects of this utility model are as follows: by starting the drive motor, the drive motor drives the driving gear to rotate, and the rotation of the driving gear causes the driven gear to drive the ball screw to rotate, thereby causing the slider slidably connected to the outer surface of the ball screw to move within the groove opened on the surface of the worktable, thus moving the placement platform. This facilitates the adjustment of the position of the steering knuckle placed on the surface of the placement platform, ensuring that the position to be pressed is below the abutment plate, thereby improving processing efficiency. However, this utility model also has certain drawbacks: during pressing, the bushing needs to be manually placed on top of the steering knuckle, increasing labor intensity. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an automotive steering knuckle pressing device, which can solve the technical problem that the bushing needs to be manually placed on top of the steering knuckle during the existing steering knuckle pressing process, which increases the labor intensity.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automotive steering knuckle pressing device includes an operating table. A feeding mechanism is provided on the top surface of the operating table, and a pressing head is provided on one side of the feeding mechanism. A fixing mechanism is provided below the pressing head. The feeding mechanism includes a support plate fixedly installed on the top surface of the operating table. A material rack is provided on the support plate. A cylinder is provided on one side of the support plate. A pusher plate is fixedly connected to the front end of the piston rod of the cylinder. The pusher plate is used to push the material at the bottom of the material rack towards the pressing head.

[0007] Preferably, the fixing mechanism includes a first support base and a second support base; the first support base is fixedly mounted on one side of the operating table and located below the pressing head, and a semi-circular positioning block is fixedly mounted on the top of the first support base. The first support base has a threaded rod inside, one end of which is rotatably connected to the inner wall of the first support base, and the other end extends out of the first support base and is connected to a motor. A left slider and a right slider are threadedly connected to the threaded rod, and a limit rod is provided on the same side of the left slider and the right slider. The two limit rods cooperate to limit the steering knuckle. The first support base has a groove for the movement of the limit rod. The second support base is fixedly mounted on the lower end of the operating table.

[0008] Preferably, the upper ends of both sides of the support base are also provided with cylinders, the piston rod of cylinders is connected to a crossbar, and a baffle is provided between the two crossbars.

[0009] Preferably, the positioning block is equipped with a sensor.

[0010] Preferably, the front end of the pusher plate is provided with an arc groove, and the height of the pusher plate matches the height of the bushing.

[0011] Preferably, the opening size at the upper end of the rack is larger than the diameter size of its lower body.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a feeding mechanism, facilitates automatic feeding of bushings, eliminating the need for manual handling and reducing labor intensity. During feeding, the cylinder drives the pusher plate to push the bushing in the support plate onto the steering knuckle below the pressing head. By setting up a baffle, excessive pushing force can be avoided, preventing the bushing from detaching from the steering knuckle and ensuring the accurate installation of the bushing on the steering knuckle.

[0014] 2. This utility model uses a fixing mechanism to facilitate the fixation of the steering knuckle, ensuring smooth press-fitting. In use, one end of the steering knuckle is positioned on the positioning block at the top of support base one, and the other end is placed on support base two. The motor drives the threaded rod to rotate, causing the two limiting rods to move towards each other, thus clamping the steering knuckle. Attached Figure Description

Detailed Implementation

[0023] The invention will now be described in detail with reference to the accompanying drawings, by way of example. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Example

[0024] like Figures 1 to 5 As shown, this utility model discloses an automotive steering knuckle pressing device, including an operating table 1. The top surface of the operating table 1 is provided with a feeding mechanism, and a pressing head 2 is provided on one side of the feeding mechanism. A fixing mechanism is provided below the pressing head 2. By setting the feeding mechanism, the bushing is automatically pushed to the top of the steering knuckle on the fixing mechanism. The bushing is then pressed into the pin hole of the steering knuckle by the pressing head 2, which reduces the wear of the steering knuckle during use.

[0025] Furthermore, in this embodiment, the feeding mechanism includes a support plate 3 fixedly installed on the top surface of the operating table 1. A gap is provided between the support plate 3 and the top surface of the operating table 1. A material rack 4 is provided on the support plate 3. The opening size at the upper end of the material rack 4 is larger than the diameter size of its lower body, which facilitates the placement of the bushing into the material rack 4. A cylinder 5 is provided on one side of the support plate 3. A pusher plate 6 is fixedly connected to the front end of the piston rod of the cylinder 5. An arc groove matching the outer diameter of the bushing is opened at the front end of the pusher plate 6. The height of the pusher plate 6 matches the height of the bushing. The pusher plate 6 is used to push the material at the bottom end of the material rack 4 toward the pressing head 2.

[0026] The fixing mechanism includes a first support base 7 and a second support base 8, which are used to support the two ends of the steering knuckle, respectively. The first support base 7 is fixed to one side of the operating table 1 and located below the pressing head 2. A semi-circular positioning block 9 is fixedly installed on the top of the first support base 7 to facilitate the positioning of the pin hole of the steering knuckle and improve the accuracy of pressing. A sensor is provided on the positioning block 9 to sense whether the steering knuckle is installed in place. A threaded rod 10 is provided inside the first support base 7. One end of the threaded rod 10 is rotatably connected to the inner wall of the first support base 7, and the other end... The first support base 7 extends from the end and is connected to a motor 11. The threaded rod 10 is connected to a left slider 12 and a right slider 13 by positive and negative threads, respectively. The left slider 12 and the right slider 13 are provided with limit rods 14 on the same side. The two limit rods 14 cooperate to clamp and limit the steering knuckle. The first support base 7 is provided with a groove 15 for the movement of the limit rods 14. By setting the threaded rod 10, motor 11, slider, limit rod 14 and groove 15, it is convenient to clamp the steering knuckle and avoid tilting. The second support base 8 is fixed on the lower end of the operating table 1.

[0027] The upper ends of both sides of the support base 7 are also provided with cylinder 2 16. The piston rod of cylinder 2 16 is connected to a cross rod 17. A baffle 18 is provided between the two cross rods 17. By setting the baffle 18, the bushing can be prevented from detaching from the steering knuckle due to excessive pushing force, thus ensuring the accurate installation of the bushing on the steering knuckle.

[0028] Working principle: First, several bushings are placed in the material rack 4 for later use. Then, the steering knuckle is placed on support base 7 and support base 8. When the sensor detects that the steering knuckle is installed in place, it sends a signal to the controller. The controller controls the motor 11 to rotate, which drives the threaded rod 10 to move the left slider 12 and the right slider 13 towards each other, thereby driving the two limit rods 14 to clamp the steering knuckle and ensure its stability. Then, the cylinder 16 moves to move the baffle 18 down to the top of the steering knuckle. After installation, the cylinder 5 moves to push the pusher plate 6 to push the bushing at the bottom of the material rack 4 to the top of the steering knuckle. After being blocked by the baffle 18, the bushing accurately stops at the top of the steering knuckle pin hole. Finally, the pressing head 2 moves downward to press the bushing into the steering knuckle, thus completing the pressing operation.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and application concept of the present utility model, should be included within the protection scope of the present utility model.
