Description

An adjustable damping buffer

technical field

The utility model relates to an adjustable damping buffer, which uses oil as the main buffering material and has better buffering performance, belonging to the technical field of buffers.

Background technique

In industry, damping buffers are often used to absorb the impact energy between machines, protect equipment, reduce noise, and ensure smooth operation of equipment. There are many damping buffers on the market at present, but the damping size of these damping buffers is fixed and cannot be adjusted. When the shock absorption effect of the damping buffer is adjusted according to the working conditions, it is necessary to replace other types of damping buffers to achieve the effect. , and replacing the damping buffer is obviously neither economical nor time-consuming, so a damping buffer that can adjust the size of the damping is very necessary.

Utility model content

The utility model aims to solve the above problems, and provides an adjustable damping buffer, which overcomes the disadvantage that the damping value of the general damping buffer cannot be adjusted, and the technical scheme adopted is as follows:

An adjustable damping buffer, including a central push rod, an adjusting nut, a spring washer, an adjusting handle, a set bolt, a damping sleeve, a sealing gland, a buffer cylinder, and a buffer spring. The lower end of the central push rod has a circle Disc-shaped grid block, there are four fan-shaped openings on the grid block, the upper end is a stepped platform, the side of the stepped platform is tapped with threads, and there is a tapped positioning hole 30mm below the step surface, the central push rod sleeve On the damping sleeve, there is a disk-shaped barrier at the lower end of the damping sleeve, and there are four fan-shaped openings on the barrier. There are two symmetrical slide rails on the outer cylindrical surface of the damping sleeve. The upper end is a Round table top, a positioning stud is welded on the table, the adjustment handle is covered on the center push rod, the arc hole of the adjustment handle is covered on the positioning stud of the damping sleeve, and the adjustment handle and the center push rod are tightly fixed. The bolt is fixed, the adjusting handle and the damping sleeve are fixed by the adjusting nut with a spring washer, the buffer spring is pressed in the buffer cylinder, and the center push rod covered with the damping sleeve is pressed on the buffer spring in the buffer cylinder. The buffer cylinder is sealed with a sealing gland. The sealing glands are two semicircular glands. The two glands are just combined into a sealed sealing cover. The middle hole formed after the combination can just pass through the The damping sleeve, the sealing gland and the buffer cylinder are interference fit, and the tight pressing ensures the sealing of the internal oil fluid. The lower end of the buffer cylinder is a flange for connecting and fixing with the outside.

The utility model has the following advantages: the damping of the buffer can be flexibly adjusted, the structure is simple, the use is convenient, safe and reliable; the trouble caused by replacing the buffer is avoided, and the production efficiency is improved.

detailed description

Below in conjunction with accompanying drawing and example the utility model is described further:

As shown in Figure 1-3, the utility model is an adjustable damping buffer, including a central push rod (1), an adjusting nut (2), a spring washer (3), an adjusting handle (4), and a set bolt ( 5), damping sleeve (6), sealing gland (7), buffer cylinder (8), buffer spring (9), the lower end of the central push rod (1) has a disc-shaped grid block, the grid block There are four fan-shaped openings on the top, and the upper end is a stepped platform. The side of the stepped platform is tapped with threads. There is a tapped positioning hole 30mm below the stepped surface. The central push rod (1) is sleeved on the damping sleeve (6 ), the lower end of the damping sleeve (6) has a disk-shaped baffle, and there are four fan-shaped openings on the baffle, and there are two symmetrical slide rails on the outer cylindrical surface of the damping sleeve (6). The upper end is a round table top, and a positioning stud is welded on the table top. The adjustment handle (4) is set on the center push rod (1), and the arc-shaped hole of the adjustment handle (4) is set on the positioning screw of the damping sleeve. On the column, the adjusting handle (4) and the central push rod (1) are fixed by the set bolt (5), and the adjusting handle (4) and the damping sleeve (6) are fixed by the adjusting nut (2) with a spring washer (3). ) is fixed, the buffer spring (9) is pressed in the buffer cylinder (8), and the central push rod covered with the damping sleeve (6) is pressed (1) on the buffer spring (9) in the buffer cylinder (8) , the buffer cylinder (8) is sealed with a sealing gland (7), and the sealing gland (7) is two semicircular glands, and the two glands are combined to form a sealed sealing cover, and the combined The middle hole of the sealing gland (7) can just pass through the damping sleeve (6) with slide rails. The sealing gland (7) and the buffer cylinder (8) are interference fit, and the tight pressing ensures that the inner For oil sealing, the lower end of the buffer cylinder (8) is a flange for connecting and fixing with the outside.

When the utility model is in use, the top stud of the central push rod (1) is connected to the equipment, and the flange plate at the lower end of the buffer cylinder (8) is connected to the machine base so that the damping buffer is fixed. When the damping needs to be adjusted, first use a wrench Loosen the adjusting nut (2), and then turn the adjusting handle (4), thereby changing the size of the clearance hole formed by superimposing the central push rod (1) and the fan-shaped surface at the lower end of the damping sleeve (6), thereby changing the cross section of the oil flow The area achieves the purpose of changing the damping size of the damping buffer.

The utility model has been described above with examples, but the utility model is not limited to the above-mentioned specific embodiments, and any changes or modifications made based on the utility model all belong to the protection scope of the utility model.
