Abstract
Description
Technical Field
[0001] This utility model belongs to the field of guide rail technology, and in particular relates to a linear guide rail for high-load applications. Background Technology
[0002] Linear guides are used to support and guide moving parts to perform reciprocating linear motion in a given direction. Linear guides are also called linear rails, slide rails, linear guides, or linear slide rails. They are used in linear reciprocating motion applications and can withstand a certain amount of torque. They can achieve high-precision linear motion under high loads. Currently, a miniature ball linear guide is commonly used.
[0003] Existing linear guides have limited load capacity, resulting in poor load-bearing capacity. When the slider on the guide is subjected to high load, the slider will jam and cannot move. Furthermore, long-term high-load use will also affect the service life of the guide. In view of this, we propose a linear guide for high-load applications. Utility Model Content
[0004] The purpose of this invention is to provide a linear guide for high-load applications to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides a linear guide for high-load applications, comprising:
[0006] A guide rail, on which a slider is slidably mounted, a support plate is fixedly mounted on the top surface of the slider, and a support platform is provided above the support plate;
[0007] Two sets of buffer components are symmetrically arranged between the support plate and the support platform;
[0008] A main damping rod is fixedly installed on the top surface of a support plate. The top of the support plate is fixedly connected to the bottom surface of a support platform. A main buffer spring is sleeved on the outer wall of the main damping rod. The top of the main buffer spring is fixedly connected to the bottom surface of the support platform, and the bottom of the main buffer spring is fixedly connected to the top surface of the support plate.
[0009] In the above technical solution, the buffer assembly further includes a first damping rod and two mounting rods. The first damping rod is fixedly installed on the top surface of the support plate. A side block is fixedly installed at the top of the first damping rod. A movable block is slidably installed inside the side block. Side rods are fixedly installed on both sides of the movable block. Two mounting plates are fixedly installed on the bottom surface of the support platform and the top surface of the support plate. The two mounting rods are fixedly installed between the four mounting plates. Two first connecting rods are rotatably installed on one of the mounting rods. The other ends of the two first connecting rods are rotatably installed on the two side rods. Two second connecting rods are rotatably installed on the outer side wall of the other mounting rod. The other ends of the two second connecting rods are rotatably installed on the two side rods. When an item is placed on the support platform, the support platform will move downward under pressure. When the support platform moves downward, the movable block will be pushed to move through the cooperation of the second connecting rods, the first connecting rods and the side rods.
[0010] In the above technical solution, the buffer assembly further includes a second damping rod, which is fixedly installed on the inner side of the side block. One end of the second damping rod is fixedly connected to one side of the moving block. A side buffer spring is sleeved on the outer wall of the second damping rod. One end of the side buffer spring is fixedly connected to the inner side of the side block, and the other end of the side buffer spring is fixedly connected to one side of the moving block. When the moving block moves, the force on the moving block is absorbed by the second damping rod and the side buffer spring. At the same time as the moving block moves, the side block will change with the height of the support platform. The first damping rod will drive the side block to retract, thereby increasing the buffering effect.
[0011] In the above technical solution, two support blocks are provided above the support plate, and multiple fixed columns are fixedly installed on the top surface of the support plate. The top ends of the multiple fixed columns are respectively fixedly connected to the bottom surfaces of the two support blocks. By setting the support blocks, when the support platform descends to a certain position, the support blocks will lift and support the support platform, thereby improving the load capacity of the support platform.
[0012] In the above technical solution, furthermore, multiple reinforcing diagonal bars are fixedly installed on both sides of the slider, and the top ends of the multiple reinforcing diagonal bars are fixedly connected to the bottom surface of the support plate. By setting multiple reinforcing diagonal bars, the support plate will be supported, the support force of the support plate will be increased, and the load-bearing effect of the support platform will be further improved, which is quite practical.
[0013] In the above technical solution, both the support plate and the support platform are made of alloy material, which has high hardness, high strength, low melting point, easy processing and high durability.
[0014] In the above technical solution, furthermore, the multiple reinforcing diagonal bars are inclined at the support plate and the slider support. By setting multiple reinforcing diagonal bars, the support plate is supported, the support force of the support plate is increased, and the load-bearing effect of the support platform is further improved, which is more practical.
[0015] The beneficial effects of this utility model are:
[0016] 1. In this high-load linear guide, when an item is placed on the support platform, the platform will move downwards under pressure. As the support platform moves downwards, the movement of the moving block is propelled by the cooperation of the second connecting rod, the first connecting rod, and the side rod. The force on the moving block is absorbed by the second damping rod and the side buffer spring. Simultaneously, the side block changes with the height of the support platform, and the first damping rod causes the side block to retract, thereby increasing the buffering effect. Furthermore, the cooperation of the main damping rod and the main buffer spring increases the load capacity of the support platform, enabling it to be used under high load conditions.
[0017] 2. In this high-load application, the linear guide rail is equipped with support blocks. When the support platform descends to a certain position, the support blocks lift and support the support platform, thereby improving its load capacity. Furthermore, the support platform and slider are made of alloy materials, which also have strong rigidity. Multiple reinforcing diagonal bars are set to support the support plate, increasing the support force of the support plate and further improving the load-bearing effect of the support platform, making it quite practical.
