Description

Buffer pressing mechanism

Technical field:

The utility model relates to a buffer pressing mechanism.

Background technique:

During the assembly process of notebooks, mobile phones and other electronic products, the separate covers need to be pressed and installed by a pressing machine. The existing pressing mechanism has a relatively large impact during the pressing process. The pressed workpieces are in hard contact without any cushioning. Sometimes the impact force is too large, which will cause damage to the pressed workpieces, and the effect of the pressed workpieces is not ideal.

Utility model content:

The purpose of the utility model is to provide a pressing mechanism with buffer function.

The technical solutions of the present utility model are as follows:

The buffer pressing mechanism includes a horizontal slide table cylinder and a support plate fixedly connected with the cylinder guide rod of the horizontal slide table cylinder, a lift slide table cylinder is fixed on the support plate, and the cylinder guide rod of the lift slide table cylinder A connecting plate is fixed on the top, and the sliders of two parallel lifting guide rails are fixed on the connecting plate, and two spring pins with springs on them pass through the horizontal plate on the connecting plate and are fixed on the two lifting guide rails. The upper end of the two lifting guide rails is fixed with a pressure head.

In the buffer pressing mechanism, the two springs sleeved on the two spring pins are located between the top ends of the two lifting guide rails and the horizontal plate.

In the buffer pressing mechanism, the cylinder of the horizontal slide table is fixed on the base of the cylinder.

In the buffer pressing mechanism, the support plate includes a bottom plate and a riser that are perpendicular to each other and are welded together. The cylinder is fixedly connected, and a reinforcing rib is welded between the bottom plate and the vertical plate.

The beneficial effects of the utility model are:

The advantages of the buffer pressing mechanism of the utility model are that the surface of the product is pressed by the buffer force of the spring to prevent the product from being crushed by the instantaneous momentum of the cylinder, and the cost is very low and the structure is simple. Because the impact speed of the cylinder is very fast, and it is fixed and uncontrollable. If the cylinder is directly used for stamping, the surface of the product is easily crushed. Compared with the low cost of the servo motor mechanism, if the servo motor mechanism is used, the impact speed can be controlled, but the cost of the servo motor is quite high, so the cost of this mechanism is low and the structure is relatively simple.

Detailed ways:

The following descriptions are only preferred embodiments of the present utility model, and are not intended to limit the scope of the present utility model.

For the embodiment, see accompanying drawings 1-5; the buffer pressing mechanism includes a horizontal slide table cylinder 1 and a support plate 2 fixedly connected with the cylinder guide rod of the horizontal slide table cylinder, and a lift plate 2 is fixed on the support plate 2 The slide table cylinder 3, the cylinder guide rod of the lift slide table cylinder is fixed with a connecting plate 4, the sliders 7, 8 of the two lifting guide rails 5, 6 are fixed on the connecting plate, the lifting guide rails 5, 6 are parallel to each other, connected A horizontal plate 11 perpendicular to each other is welded on the flat plate, two through holes are arranged on the horizontal plate, and two spring pins 9, 10 with springs 14, 15 on it pass through the horizontal plate 11 on the connecting plate and are fixed on the flat plate. The upper ends of the two lifting guide rails mentioned above, the diameter of these two through holes is larger than the part through which the spring pin passes, so that the spring pin can slide in it, and there are two round tables with a diameter larger than the spring pin on the top of the two spring pins , used to prevent that in the process of descending, the spring pin passes through the two round holes of the horizontal plate, and the lower ends of the two lifting guide rails are fixed with pressure heads 12,13.

In the buffer pressing mechanism, the two springs sleeved on the two spring pins are located between the top ends of the two lifting guide rails 5 , 6 and the horizontal plate 11 . When the two lifting guide rails were at rest in their original positions, the two springs were in a free state.

In the buffer pressing mechanism, the cylinder of the horizontal slide table is fixed on the cylinder base 17 .

In the buffer pressing mechanism, the support plate 2 includes a bottom plate 201 and a vertical plate 202 that are perpendicular to each other and welded together, and the bottom plate is fixedly connected with the cylinder guide rod of the cylinder of the horizontal slide table. The cylinder of the lifting slide is fixedly connected, and a reinforcing rib 203 is welded between the bottom plate and the vertical plate.

Working principle: The working steps and principle of the buffer pressing mechanism, the state of the mechanism before stamping the product is shown in Figure 1, and the pressure head does not touch the product. The top of the spring pin is stuck on the top of the cross plate, and at this time, the two springs are in a naturally stretched state. The working state of the mechanism pressing product is shown in Figure 4 and Figure 5. First look at Figure 4, the cylinder of the slide table slides out a part, the pressure head and the slide rail move down together with the vertical plate and the horizontal plate, and the slide There is no mutual sliding between the rail and the slider. At this time, the guide rod of the cylinder of the lifting slide has been extended, but not fully extended. At this time, the pressure head has touched the surface of the product, and the spring is still in the natural tension. In the extended state, there is no pressure between the indenter and the product surface. Then the cylinder of the slide table continues to slide downward, while the pressure head and the slide rail part stop moving downward, the slide rail and the slider slide relative to each other, and the top of the horizontal plate begins to slowly compress the spring downward. The elastic force generated by the compressed spring is the compression The force of pressing the product by the head, when the cylinder of the slide table is extended from short to long, the spring will be shortened from long to short, and the elastic force will be changed from small to large, so a buffer pressure is generated, which is the working principle of the buffer press mechanism.
