Description

Technical Field

[0001] The utility model relates to the technical field of buffers, in particular to a novel adjustable buffer of an elastic linear guide rail. Background Art

[0002] Linear guides can be divided into three types: roller linear guides, cylindrical linear guides, and ball linear guides. They are used to support and guide moving parts to perform reciprocating linear motion in a given direction. Depending on the nature of friction, linear motion guides can be divided into sliding friction guides, rolling friction guides, elastic friction guides, fluid friction guides, and other types. In order to buffer them, buffers will be used. Buffers have the advantages of improving mechanical efficiency and increasing production capacity, extending machine life and reducing maintenance costs, stabilizing mechanical movements, and making machine operations safer and avoiding accidents. The existing adjustable buffer adjusts the oil pressure by adjusting the position of the internal constraint block to change the buffer's buffering effect. The existing constraint block is generally a rubber ring block. When the buffer rod is squeezed, the oil may squeeze the constraint block and deform and leak, causing damage to the buffer. For this reason, we propose a new type of adjustable buffer for elastic linear guides. Utility Model Content

[0003] The utility model mainly solves the technical problems existing in the above-mentioned prior art and provides a new type of adjustable buffer for elastic linear guide rail.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a new type of adjustable buffer with elastic linear guide rail, including a buffer cylinder, a movable rod, an impact block, a fixed block and a movable block, an adjustment assembly is arranged on the lower side of the buffer cylinder, a connecting block is fixedly installed on the upper side of the constraint block and the connecting block is fitted on the inner side of the buffer cylinder, a groove is opened on the side of the connecting block, a sealing ring is fixedly installed on the inner wall of the groove and the sealing ring is fitted on the inner side of the buffer cylinder, a support ring is fixedly installed on the inner side of the sealing ring and the support ring is fitted on the inner wall of the groove, a deformation ring is fixedly installed between the support ring and the sealing ring, and a reinforcement ring is fixedly installed inside the deformation ring.

[0005] As a preferred technical solution of the utility model, the adjustment assembly includes a mounting block, an adjustment rod, an adjustment block, an extrusion block, a constraint block and a connecting tube. The mounting block is fixedly installed at the bottom side of the buffer cylinder, the adjustment rod is threadedly installed inside the mounting block and the adjustment rod extends through the buffer cylinder, the adjustment block is fixedly connected to the side of the adjustment rod, the extrusion block is fixedly connected to the side of the adjustment rod away from the adjustment block, the constraint block is arranged at the inside of the buffer cylinder and fits on the upper side of the extrusion block, and the connecting tube is fixedly connected between the side of the constraint block and the bottom side of the buffer cylinder.

[0006] As a preferred technical solution of the utility model, the restraining block is a circular block made of rubber material, and the connecting cylinder is a cylinder made of spring steel with a continuous W-shaped cross section.

[0007] As a preferred technical solution of the utility model, a sealing block is fixedly installed inside the movable block and the sealing block is attached to the inner side of the buffer cylinder. The sealing block is a rubber ring block with a convex cross-section.

[0008] As a preferred technical solution of the present utility model, the connecting block is a truncated cone block made of rubber material with a hollow side.

[0009] Beneficial Effects

[0010] The utility model provides a new type of adjustable buffer for elastic linear guide rails, which has the following beneficial effects:

[0011] The novel adjustable buffer of the elastic linear guide rail changes the position of the constraint block by adjusting the adjusting rod in the mounting block through the adjusting block during use. Meanwhile, the connecting tube pulls the constraint block to change the oil pressure inside the buffer cylinder. The impact block is impacted so that the movable block squeezes the oil inside the buffer cylinder. The oil is squeezed on the side of the connecting block so that the connecting block expands and deforms toward the inside of the buffer cylinder. The synchronous sealing ring squeezes the inside of the buffer cylinder under the support of the supporting ring to play a sealing role. The deformation ring strengthens the support between the supporting ring and the sealing ring. The reinforcing ring strengthens the structural stability of the deformation ring and further enhances the support for the sealing ring. This avoids the possibility that the oil may squeeze the constraint block to deform and leak when squeezed. BRIEF DESCRIPTION OF THE DRAWINGS
