Description

Technical Field

[0001] The utility model relates to the technical field of press-fitting of a steering gear rack support sleeve, in particular to a press-fitting and closing mechanism for a steering gear rack support sleeve. Background Technique

[0002] With the rapid development of the new energy vehicle market, especially the popularization of electric vehicles and hybrid vehicles, the automotive industry is undergoing profound technological upgrades and industrial transformations. This trend poses higher requirements for the production of automotive parts, namely, complex structures, improved precision, enhanced safety performance, and the need to achieve mass production to meet market demands. During the manufacturing process of the steering system, as a key component connecting the steering wheel and the wheels, the stability and reliability of the steering gear directly affect the handling performance and safety of the vehicle.

[0003] Traditional methods for press-fitting a steering gear rack support sleeve often rely on manual operations, which are not only inefficient but also difficult to ensure the precision and consistency of the press-fitting. In actual production, problems such as missed press-fitting of parts or springback after press-fitting often occur. These problems not only increase friction, reduce the overall performance and lifespan of the steering system, but may also cause partial loss of vehicle functions or even lead to safety accidents. Content of the Utility Model

[0004] The technical problem solved by the utility model is to overcome the defects mentioned in the background technique.

[0005] To achieve the above object, the utility model provides the following technical solution: A press-fitting and closing mechanism for a steering gear rack support sleeve, including a pressure head, an actuator, and a hydraulic cylinder; the front end of the hydraulic cylinder is connected to the pressure head through a spring support rod, and an actuator is installed at the front end of the pressure head. Four groups of notches are provided on the housing of the actuator, three groups of hard supports are provided inside the housing of the pressure head, and a group of soft supports are provided on the side inside the housing of the pressure head.

[0006] Further, the hard support is a cylindrical structure made of plastic material, the three groups of hard supports are identical, and the height of the hard support is lower than the protruding height of the housing of the actuator.

[0007] Further, there are two large notches and two small notches provided on the actuator.

[0008] Further, the pressure head installed at the front end of the hydraulic cylinder is connected to the actuator through a nut, and two groups of hydraulic cylinders are independently connected to two groups of actuators respectively.

[0009] Further, the operation of the pressure head pushes the hydraulic cylinder to convey and extrude a rubber bushing, and the rubber bushing does not contact the wall of the stop hole.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] By directly driving the punch through a hydraulic cylinder and combining the design of the actuator, rapid and stable press-fitting of the steering gear rack support sleeve is achieved, significantly improving production efficiency. The modular design makes the connection of each component tight and easy to operate, reducing errors caused by manual operation and improving the stability and consistency of press-fitting; the four groups of notch designs on the actuator and the combination of hard support and soft support inside the punch ensure that the rubber bushing does not directly contact the housing during the press-fitting process, avoiding friction and damage and improving the press-fitting accuracy; the hard support is made of plastic material, which not only prevents the rubber bushing from being bruised but also ensures the smoothness of press-fitting, further improving the product quality.

[0012] The design of this mechanism realizes automatic press-fitting, reduces the dependence on manual operation, thereby reducing labor costs; due to high press-fitting accuracy and good stability, the rework rate caused by problems such as incomplete press-fitting or springback is greatly reduced, saving production costs.

[0013] The punch installed at the front end of the hydraulic cylinder is connected to the actuator through a nut, and the two groups of hydraulic cylinders are independently connected to the two groups of actuators respectively. This design enables the mechanism to be flexibly adjusted according to different steering gear models and requirements, enhancing the applicability and flexibility of the equipment; automatic press-fitting reduces manual operation, reduces the labor intensity of workers on the production line, and improves the working environment.

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figure 1-2 , the present utility model provides a technical solution: a press-fitting and closing mechanism for a steering gear rack support sleeve, and the specific structure and operation method are as follows:

[0019] This mechanism mainly consists of three major parts: a punch 1, an actuator 2, and a hydraulic cylinder 3. The hydraulic cylinder 3 serves as the power source and is connected to the punch 1 through a spring support rod to ensure that the punch 1 can perform the pressing operation stably and powerfully. At the front end of the punch 1, the actuator 2 is installed. Four groups of notches 6 are carefully designed on the housing of the actuator 2 to meet different pressing requirements and enhance stability.

[0020] Three groups of hard supports 5 are arranged inside the housing of the actuator 2. These three groups of hard supports 5 are all cylindrical structures made of plastic material, with the same size and shape, to prevent the rubber bushing from being misaligned or damaged during the pressing process. The height of the hard support 5 is designed to be lower than the protruding height of the housing of the actuator 2 to ensure that unnecessary pressure or damage will not be caused to the rubber bushing during the pressing process.

[0021] In addition, a group of soft supports 4 are arranged on the inner side of the housing of the punch 1. The soft support 4 is made of black rubber material and mainly plays a buffering role to further protect the stability and safety of the rubber bushing during the pressing process.

[0022] The four groups of notches 6 on the actuator 2 are specifically divided into two large notches and two small notches. This design is to provide reverse support for the steering gear housing to prevent the housing from deforming during the pressing process, thereby improving the pressing accuracy and stability.

[0023] The punch 1 installed at the front end of the hydraulic cylinder 3 is tightly connected to the actuator 2 through a nut to ensure that the two can work together during the pressing process without loosening or misalignment.

[0024] To improve efficiency and flexibility, this mechanism is designed with two groups of hydraulic cylinders 3 and two groups of actuators 2. They are independently connected and operated respectively, and can perform the pressing operation simultaneously or separately according to needs.

[0025] During operation, the hydraulic cylinder 3 provides power to drive the punch 1 to move forward. The punch 1 drives the actuator 2 to press the rubber bushing together.

[0026] Due to the synergistic effect of the three groups of hard supports 5 and a group of soft supports 4 inside the actuator 2, the rubber bushing can maintain the correct position and stable posture during the pressing process.

[0027] At the same time, the four groups of notches 6 on the actuator 2 provide the necessary reverse support for the steering gear housing, preventing the housing from deforming and being damaged.

[0028] Finally, the rubber bushing is accurately pressed into the stop hole of the steering gear housing, achieving an efficient, accurate and stable pressing operation.

[0029] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
