Background technique

The shock absorber is an indispensable and important part of the vehicle suspension system. It is mainly used to suppress the shock when the shock-absorbing spring rebounds after absorbing the shock and the impact from the road. The oil storage cylinder assembly of the shock absorber is composed of the oil storage cylinder and the bottom cover, and the oil storage cylinder and the bottom cover are interference fit. At present, the press-fitting method commonly used in the press-fitting process of the oil storage tank assembly is: the oil storage tank is on the bottom, the bottom cover is on the top, the oil storage tank is placed vertically on the workbench of the tooling, and the bottom cover is placed on the top of the oil storage tank port, and then use the oil cylinder or air cylinder to drive the pressure head to move down to press the bottom cover into the oil storage tank. The disadvantages of using this method to press-fit the bottom cover are: first, it is difficult to control the operating speed of the oil cylinder or air cylinder, resulting in uncontrollable press-fit quality of the product; During assembly, the momentary force on the bottom cover is relatively large, resulting in damage to the bottom cover and the oil storage tank, and a high scrap rate of the product.

Utility model content

The purpose of this utility model is to provide a bottom cover press-fitting mechanism of a shock absorber welding machine in view of the defects and deficiencies of the prior art. Quality, reduce product scrap rate.

In order to achieve the above object, the utility model adopts the following technical solutions:

The bottom cover press-fitting mechanism of a shock absorber welding machine described in the utility model includes a frame and a vertical screw rod, the top of the frame is provided with a motor, and the motor communicates with the motor through a reducer. The top end of the screw rod is connected by transmission, and the bottom end of the screw rod is connected with an indenter mounting seat through a screw nut. There is a linear slide rail, and a slide block that slides and cooperates with the linear slide rail is arranged on the mounting seat of the pressure head.

Further, the top of the frame is provided with a mounting frame for installing the reducer, and the screw rod passes through the mounting frame and is connected to the reducer in transmission; the connection between the mounting frame and the screw rod A bearing seat and a bearing are sequentially arranged between the bearing seat, and the bearing seat is fixedly connected with the mounting frame through a bearing seat fixing plate.

Further, a connection plate is provided on the indenter installation seat, and a connection seat for installing the slider is provided on the connection plate.

The beneficial effects of the utility model are as follows: the utility model is provided with a frame and a vertical screw rod, and a motor, a reducer and a linear slide rail are respectively arranged on the frame, and the top of the screw rod is driven by the reducer and the motor. Connection, the bottom end of the screw rod is connected with the screw nut to set the pressure head mounting seat, the bottom end of the pressure head mounting seat is provided with the pressure head for pressing the bottom cover, and the pressure head mounting seat is also set to slide with the linear slide rail When working with the matching slider, place the oil storage cylinder assembly to be pressed on the workbench, place the bottom cover on the upper port of the oil storage cylinder, start the motor, and the reducer drives the screw to rotate, and the linear slide rail and Under the cooperative action of the slide block, the screw rod drives the pressure head mounting seat to move vertically downward through the screw screw nut during the rotation process, thereby impelling the pressure head to accurately press the bottom cover into the proper position of the oil storage cylinder to complete the pressing operation.

To sum up, the utility model has a simple and reasonable structure and low manufacturing cost. By controlling the rotating speed of the screw rod, the running speed of the indenter can be controlled, which makes the control more convenient, and the force on the bottom cover is more uniform, thereby effectively improving the product quality. Excellent pressing quality, reduce product scrap rate.
