Description

A square rubber hinge pressing device

technical field

The utility model belongs to the technical field of mechanical tooling, and relates to a square rubber hinge pressing device, which is especially suitable for pressing the square rubber hinge of a car chassis.

Background technique

In the chassis of a car, the common rubber hinge has a round shape and is relatively easy to press and fit. A certain car chassis product has special structural design requirements, and a square rubber hinge is used at the wheel bracket. In the process of pressing into the square hole of the wheel bracket, ensure that the upper and lower planes of the square hinge are parallel to the upper and lower planes of the square hole of the wheel bracket. Wrinkles, damage, trimming, etc. are not allowed, and at the same time, ensure that the upper plane of the square hinge is Dimensional requirements on the plane with the wheel bracket. This kind of square rubber hinge is difficult to press-fit with traditional round hinge press-fitting devices, and it is easy to produce wrinkles, damage, trimming, etc. when using existing press-fitting tools, and the scrap rate is high.

Contents of the invention

The utility model discloses a square rubber hinge press-fitting device to solve the problems in the prior art that the press-fitting scrap rate of the existing press-fitting tool is high, it is difficult to press-fit, and the like.

The utility model comprises a pressure head, a necking ring, a spring, a spring guide column, a square hinge positioning pin, a necking ring support, and a workpiece fixture; The head is installed on the pressing machine; the square hinge positioning pin is installed on the pressing head; the spring is installed on the spring guide column; the upper part of the spring guide column is fastened and installed on the press machine; On the workpiece fixture, the necking ring support is located under the pressure head and on the workpiece fixture; the necking ring is installed on the necking ring support and is located above the workpiece fixture; the square rubber hinge is inserted into the square hinge positioning pin; the workpiece is placed on the workpiece fixture; Start the press machine, and the pressure head will move downward in a straight line; the shrink ring supports the compression spring and moves upward along the spring guide column; the square rubber hinge produces up and down deformation and presses into the shrink ring.

The utility model has a square conical necking ring with an arc-shaped cross-section and a square corner.

The square opening above the necking ring is larger than the size of the bottom surface of the square rubber hinge, the square opening below the necking ring is equal to the size of the square hole of the wheel bracket, and the size of the indenter is equal to the size of the square hole of the wheel bracket; Secure so that the square hinge is pressed smoothly into the wheel bracket. The entire stroke is just enough to ensure that the square rubber hinge is pressed into the wheel bracket and meets the size requirements without wrinkles, damage, or trimming.

The positive effect of the utility model lies in that problems such as wrinkles, damage, edge trimming and the like that are easily generated during the press-fitting process of the square hinge are eliminated. Accurate and fast positioning greatly reduces the scrap rate during the square hinge press-fitting process; saves processing time, reduces operating beats, and greatly improves production efficiency; reduces labor intensity of workers; reduces costs, and has strong practicality sex.

detailed description

An embodiment of the utility model will be described in detail below in conjunction with the accompanying drawings.

The embodiment of the utility model is shown in Fig. 1, Fig. 2 and Fig. 3, including a pressure head 1, a necking ring 2, a spring 3, a spring guide column 4, a square hinge positioning pin 5, a necking ring support 6, and a workpiece fixture 7; The necking ring is in the shape of a square cone, and the upper square mouth of the necking ring is larger than the lower square mouth; the pressure head 1 is installed on the press machine; the square hinge positioning pin 5 is installed on the pressure head 1; the spring 3 is installed on the spring guide column 4; The top of the spring guide column 4 is fastened and installed on the press-fitting machine; the bottom of the spring guide column 4 is slidably installed and fixed on the workpiece fixture 7 with the necking ring support 6, and the necking ring support 6 is located under the pressure head 1 and on the workpiece fixture 7; The necking ring 2 is installed on the necking ring support 6 and is located above the workpiece fixture 7 . The square opening above the necking ring 2 is larger than the size of the bottom surface of the square rubber hinge J1, the square opening below the necking ring 2 is equal to the size of the square hole of the wheel bracket, and the size of the indenter 1 is equal to the size of the square hole of the wheel bracket;

As shown in Figure 1, before pressing, the square rubber hinge J1 is inserted into the positioning pin 5 of the square hinge; the workpiece is placed on the workpiece fixture 7.

As shown in Figure 1, start the press-fitting machine, the pressure head 1 moves downward in a straight line; the shrink ring supports 6 to compress the spring 3, and moves upward along the spring guide column 4; the square rubber hinge J1 produces large and small deformations and presses into the shrink Ring 2, deformed into a square rubber hinge J2.

Through the profiling compression and fixation of the square hinge by the shrink ring, the square hinge is smoothly pressed into the wheel bracket. The entire stroke is just enough to ensure that the square rubber hinge is pressed into the wheel bracket and meets the size requirements without wrinkles, damage, or trimming.
