Description

Technical Field

[0001] This utility model relates to the field of bushing assembly and disassembly technology, and in particular to a tooling for pressing steel bushings for automotive front steering knuckles. Background Technology

[0002] The steering knuckle, also known as the "steering knuckle," is a crucial component of the automotive steering axle, enabling stable vehicle movement and sensitive directional transmission. Its function is to transmit and bear the load from the front of the vehicle, supporting and driving the front wheels to rotate around the kingpin, thus steering the car. While the vehicle is in motion, it withstands varying impact loads.

[0003] With the development of the automotive industry and the improvement of people's living standards, users have placed higher demands on the comfort of automobiles, and OEMs have also set more stringent requirements for comfort. Consequently, the structure and assembly process of steering knuckles face more stringent requirements. The steel sleeve of this type of steering knuckle is press-fitted from the inside out, and the internal space is relatively small, making it impossible to produce a good traditional pressure head. If reverse pressure is applied, it is impossible to accurately position the relative position between the product body and the steel sleeve. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a tooling for pressing steel sleeves for automotive front steering knuckles, which has the characteristics of facilitating product positioning, realizing reverse pressing assembly of steel sleeves, and improving pressing efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A tooling for pressing steel sleeves of automotive front steering knuckles is provided, including a base plate, a transverse push assembly, and a transverse push block. A lower pressing head is installed in the middle of the upper end face of the base plate, and a lower pressing template is installed above the lower pressing head. A transverse push assembly is installed on the right side of the base plate, and a transverse push block that moves left and right is installed on the transverse push assembly. The transverse push block includes a push block seat, a vertical slide rail, and a vertical sliding block. The left side of the push block seat is vertically planar, and a tooling is installed in the middle of the left side of the push block seat. The base plate is equipped with a vertical slide rail, on which a vertical sliding block is mounted. A downward pressure limiting rod extending horizontally to the left is mounted on the vertical sliding block. Two elastic support shafts arranged side by side are mounted on the left and right sides of the upper end face of the base plate. A left support block is mounted between the upper ends of the two elastic support shafts on the left side, and a right support block is mounted between the upper ends of the two elastic support shafts on the right side. The downward pressure limiting rod passes horizontally through the upper middle part of the left and right support blocks. The lower end of the downward pressure template is engaged with the downward pressure limiting rod.

[0006] In this technical solution, a lower pressing head is installed to facilitate the installation of the steel sleeve, allowing the steel sleeve to be installed from bottom to top. At the same time, a transverse push block is installed to facilitate the introduction of the lower pressing limit rod. The left and right support blocks are installed to limit both ends of the lower pressing limit rod, so that when the lower pressing limit rod is pressed down, it is subjected to the elastic force of the elastic support shaft facing upward, reducing the impact force and ensuring stable pressing operation. The lower pressing template is installed to achieve pressing.

[0007] As a supplement to this technical solution, the transverse push assembly includes a transverse extension base plate, a transverse cylinder, a central guide post, and a side guide post.

A central guide post and a side guide post are arranged side by side between the two longitudinal supports. The injection shaft of the transverse cylinder is connected to the push block seat. The central guide post and the side guide post pass through the middle and rear part of the push block seat. A cylinder operating rod is installed on the right end of the transverse extension base plate.

[0008] In this technical solution, a horizontal cylinder is installed to drive the push block seat to move horizontally, so that the push block seat can push the downward limit rod, so that the downward limit rod can be positioned above the product. At the same time, the installation of the middle guide post and the side guide post allows the push block seat to move smoothly.

[0009] As a supplement to this technical solution, the push block seat includes a base and a reinforcing push block. The base is connected to the injection shaft of the transverse cylinder. The reinforcing push block is installed on the base. The reinforcing push block has an L-shaped plate structure. The bent part of the reinforcing push block is provided with triangular reinforcing ribs arranged vertically and horizontally.

[0010] In this technical solution, a mounting base is used to connect with the injection shaft of the transverse cylinder, and a reinforcing push block is used to improve the structural strength of this part.

[0011] As a supplement to this technical solution, the pressing template includes a pressing plate, vertical snap-fit ​​panels, and side reinforcing plates. Two vertical snap-fit ​​panels are symmetrically installed on the lower end surface of the pressing plate. A side reinforcing plate is installed on the front side of the middle of the two vertical snap-fit ​​panels. A slot structure is provided at the lower middle of the vertical snap-fit ​​panels to cover the upper side of the pressing limit rod. The slot structure ensures that the pressing template can connect with the pressing limit rod.

[0012] As a supplement to this technical solution, the upper side of the pressure limiting rod is provided with two anti-slip grooves that match the slot structure. By designing the anti-slip grooves, the pressure template will not deviate from the pressure limiting rod when it is pressed down.

[0013] As a supplement to this technical solution, two product positioning rods are installed side by side at the center of the upper end face of the base plate to ensure the positioning of the product.

[0014] As a supplement to this technical solution, several sensor columns are installed on the upper left side of the base plate. Each sensor column includes a vertical L-shaped bracket, a sensor structure, and a sensor protective housing. The vertical L-shaped bracket is installed on the base plate, and the sensor protective housing is installed on the upper end of the vertical L-shaped bracket near the lower pressing head. The sensor structure is installed inside the sensor protective housing, and an extension opening is provided on the lower side of the sensor protective housing. The trigger rod of the sensor structure extends from the extension opening. The installation of the sensor columns ensures that the product is installed in place before pressing operation, thus ensuring production safety.

[0015] Beneficial effects: This utility model relates to a pressing fixture for automotive front steering knuckle steel sleeves. A lower pressing head facilitates the installation of the steel sleeve, allowing it to be installed from bottom to top. A transverse push block facilitates the introduction of a downward pressing limit rod. Left and right support blocks limit the ends of the downward pressing limit rod, ensuring it is subjected to an upward elastic force from the elastic support shaft during pressing, reducing impact and ensuring stable pressing operation. A pressing template is installed to achieve the pressing process. This fixture features convenient product positioning, reverse pressing assembly of the steel sleeve, and improved pressing efficiency. Attached Figure Description
