Problems solved by technology

Therefore, when the bearing is assembled with the housing hole, a relatively large external force is required to push the bearing into the housing hole, and in the process of installing the bearing into the housing hole, the first thing to overcome is the friction / extrusion force, and the friction force is overcome. Force / extrusion force needs to apply external force to the shell itself. Through the movement of the shell, the bearing that is stationary on the indenter is pressed into the bearing hole of the shell. The shell itself bears all the pressure, which is easy to cause the shell deformation of
However, the existing assembly method of the bearing and the shell hole has eliminated the original manual hammering installation, and the press machine using the above principle is used for one-way installation, and the external force is always used to push the movement of the shell to press the bearing into the shell. In the body hole, the shell bears all the pressure of the press, causing deformation of the shell, and the position accuracy is out of tolerance, which seriously affects the assembly quality of the engine shell and box

Embodiment 1

[0033] Such as figure 1As shown: a counter-pressing mechanism, which is composed of a pre-pressing head 1 and a counter-pressing head 2. The head 2 is aligned with the central axis, the pre-press head 1 and the counter-press head 2 are driven by the driving mechanism, and the pre-press head stops after touching the shell, and the counter-press head moves closer to the bearing installation position and presses the bearing into the housing hole. The driving mechanism is composed of a pre-pressing oil cylinder 3 and a counter-topping oil cylinder 4. The pre-pressing oil cylinder 3 drives the pre-pressing head 1 to move toward the counter-pressing head 2, and the counter-topping oil cylinder 4 drives the counter-pressing head 2 to move toward the pre-pressing head 2. The indenter moves in 1 direction. Described driving mechanism is fixed by frame body, and described frame body is made up of upper fixed plate 5a, lower fixed plate 5b, column 5c, upper guide plate 5d and lower gui...

Abstract

The invention discloses an opposite-vertex opposite pressing mechanism which comprises a prepressing head and an opposite-vertex pressing head, wherein the prepressing head and the opposite-vertex pressing head are oppositely arranged, and the prepressing head and the opposite-vertex pressing head are coaxial; and the prepressing head and the opposite-vertex pressing head are driven by a driving mechanism to move closer to a bearing mounting site and load a bearing into a housing hole. The invention also discloses opposite-vertex opposite pressing equipment which comprises the opposite-vertexopposite pressing mechanism. During bearing mounting, the opposite-vertex opposite pressing mechanism can effectively solve the problem of deformation of a product housing caused by the impact force of the driving mechanism on the product housing by the upper and lower force balance of the driving mechanism. The equipment has the effect that the mechanism can achieve, and can also be suitable formulti-site mounting of different products, and the universality is stronger. A horizontal table and a product positioning table can be replaced according to the type of products, and the compatibilityof multiple products is improved, so that the flexible production is realized.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a top-and-press mechanism and a top-and-press device. Background technique [0002] The cooperation between the outer ring of the bearing and the hole of the housing adopts the base shaft system. The tightness of the fit is determined according to the size, nature, and speed of the bearing's working load. When the speed is high, the load is heavy, and the impact and vibration are serious, a tighter fit should be selected, and the bearing with high rotation accuracy requirements should also be tighter. Therefore, when the bearing is assembled with the housing hole, a relatively large external force is required to push the bearing into the housing hole, and in the process of installing the bearing into the housing hole, the first thing to overcome is the friction / extrusion force, and the friction force is overcome. Force / extrusion force needs to apply external force...
