Description

Technical Field

[0001] This utility model relates to the field of suspension bushing assembly, and in particular to a tooling for pressing a stabilizer bar connecting bushing. Background Technology

[0002] Traditional press fitting is basically a modification of an existing vertical hydraulic press, which results in low assembly accuracy and slow production efficiency. Furthermore, the vertical tooling structure requires operators to insert their limbs into the press fitting equipment each time they need to access a part. Considering the high working force of hydraulic equipment, its slow instantaneous response, and its difficulty in emergency stopping, this method reduces the risk factor of on-site operations. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the purpose of this utility model is to provide a press-fitting tool for a stabilizer bar connecting bushing, which improves production efficiency and operational safety by changing the equipment structure.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A stabilizing bar connecting bushing press-fitting fixture includes a press-fitting mechanism and a positioning mechanism arranged coaxially. The positioning mechanism includes a base, an end cap, and a slide rod that slides coaxially within a sliding space between the base and the end cap.

[0006] In a preferred embodiment of the present invention, the slide bar is composed of a boss and a guide rod. The boss is placed inside the end cap and extends from the end cap toward the pressing mechanism. The guide rod passes through from one side of the base and is connected to the boss.

[0007] In a preferred embodiment of the present invention, the sliding space is composed of the inner cavity of the base and the inner cavity of the end cap, and the boss can only slide in the inner cavity of the end cap.

[0008] In a preferred embodiment of the present invention, a guide ring is provided between the boss and the guide rod, extending radially and contacting the wall of the end cap cavity, so that the boss can slide stably in the end cap cavity.

[0009] In a preferred embodiment of this utility model, a reset component is also sleeved on the guide rod.

[0010] In a preferred embodiment of this utility model, the pressing mechanism and the positioning mechanism are horizontally opposed to each other.

[0011] In a preferred embodiment of the present invention, the pressing mechanism has a pressing head and a driver for driving the pressing head to move coaxially toward the slide bar.

[0012] In a preferred embodiment of this invention, the driver is a cylinder.

[0013] The beneficial effects of this utility model are as follows:

[0014] The present invention provides a stabilizing rod connecting bushing pressing fixture, which uses a horizontally opposed structure to make the positioning mechanism and the pressing mechanism coaxially opposed, and uses a slide rod with a coaxial integrated structure to ensure the positioning accuracy during the pressing process.

[0020] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. The above description is for the purpose of simplifying the description of this utility model and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0021] Unless otherwise specified, the singular forms “a,” “the,” and “the” used in this specification include the plural forms. The terms “comprising,” “including,” and “containing” used in this specification indicate the presence of the claimed feature, but do not exclude the presence of one or more other features.

[0022] When a component is described in the specification as being "on", "fixed" to, "connected" to, or "joined" to another component, the component may be directly located on, fixed to, connected to, joined to, or in contact with the other component, or there may be an intermediate component present.

[0023] Exemplary embodiments of this application will now be described with reference to the accompanying drawings. However, it should be understood that this application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide further additional embodiments. Throughout the drawings, the same reference numerals denote the same or functionally identical elements.

[0024] Figure 1 and Figure 2 The overall structure of the complete press-fit fixture is shown, including a horizontally arranged positioning mechanism 30 and a press-fit mechanism 20 fixed on a base plate 40. The suspension component 10 is fixed to the positioning mechanism 30, and the bushing 11 is fixed to the positioning pin 22 of the press-fit mechanism 20. The actuator 21 drives the positioning pin 22 to press the bushing into the mounting hole of the suspension component 10 through the pressure head 23. The actuator 21 is a cylinder.

[0025] The positioning mechanism 30 and the pressing mechanism 20 are coaxially opposed to ensure that the bushing 11 can be accurately fed into the positioning mechanism 30. The positioning mechanism mainly consists of a sliding seat composed of a base 36 and an end cap 37, and a slide rod 31 disposed in the sliding seat. The base 36 is hollow to form a base cavity 36a, and the end cap 37 is provided with an end cap cavity 37a. The base cavity 36a and the end cap cavity 37a form a closed sliding space, which restricts the stroke of the slide rod 31. The slide rod 31 has guide rods 32 and bosses 33 located at opposite ends. The bosses 33 are placed in the end cap cavity 37a and can extend from the end cap 37 toward the pressing mechanism 20. Thus, the suspension component 10 is sleeved on the bosses 33 through its mounting hole, and the guide rods 32 pass through the base 36 and are connected to the bosses 33. The inner cavity 36a of the base and the inner cavity 37a of the end cap have unequal diameters, allowing the boss 33 to slide only within the inner cavity 37a of the end cap and preventing it from entering the inner cavity 36a of the base. A guide ring 34, extending radially between the boss 33 and the guide rod 32, is provided to contact the inner wall of the inner cavity 37a of the end cap. This ensures that the boss 33 remains stable during sliding. The guide rod 32, the boss 33, and the guide ring 34 are coaxial with the locating pin 22. A reset component 35, which provides a reset elastic force to the boss 33 and is clamped at both ends by the guide ring 34 and the base 36, is also fitted on the guide rod 32, allowing the boss 33 to extend from the end cap 37a side without being squeezed by other external forces. Preferably, the reset component 35 can be a helical spring fitted on the guide rod 32.

[0026] The bushing 11 is mounted on the locating pin 22 and is driven by the driver 21 to be pressed into the mounting hole. During this process, the bushing 11 squeezes the boss 33, forcing the slide bar 31 to retract synchronously, and the reset part 35 is compressed. When the pressing mechanism 20 retracts, the reset part 35 is released, causing the boss 33 to move in the opposite direction, pushing the bushing 11 and the suspension component 10 together away from the tooling.
