Linear guide rail sliding block with buffering function

Abstract

The linear guide rail sliding block with the buffering function comprises a sliding block body, end covers are installed at the two ends of the sliding block body, first sliding rods are connected to the two sides of the end covers in a sliding mode, anti-collision heads are fixedly connected to the outer ends of the first sliding rods, and the anti-collision heads are elastically connected with the end covers through first springs. The other end of the first sliding rod is fixedly connected with a second limiting block. When sliding movement is blocked, the anti-collision head installed at the end of the sliding block makes contact with a blocking object in advance at the moment, then the anti-collision head is stressed to drive the first sliding rod to retract into the sliding block, and therefore the buffering effect is achieved, the sliding block is effectively protected, the service life of the steel ball is prolonged, and the service life of the steel ball is prolonged. And meanwhile, when the first sliding rod slides, an inclined block is driven to move, the inclined block extrudes an inclined groove to drive a movable block to slide, a rubber pad on the side face of the movable block makes contact with the side of the guide rail, sliding block locking and braking are achieved, sliding block and sliding are avoided, and therefore the sliding block is further protected.

Description

Technical Field

[0001] This utility model relates to the field of guide rail slider technology, specifically to a linear guide rail slider with a buffer function. Background Technology

[0002] Linear guide sliders mainly consist of sliders and guide rails. Sliders are mainly used in sliding friction guides. Linear guides, also known as linear rails, slide rails, linear guides, or linear slide rails, are used in linear reciprocating motion applications and can withstand a certain amount of torque, enabling high-precision linear motion under high loads.

[0003] In existing technology, the slider lacks a buffer device when sliding. When the slider moves to the end of the guide rail, it is obstructed, which causes the slider to impact and thus affects the slider's accuracy.

[0004] Therefore, it is of great significance to provide a linear guide slider with a buffer function to solve the problems existing in the prior art. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a linear guide slider with a buffer function to solve the problem in the prior art where the slider lacks a buffer device when sliding, and the slider is obstructed when it moves to the end of the guide rail, which causes the slider to impact and thus affects the slider accuracy.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A linear guide slider with a buffer function includes a slider body, with end caps installed at both ends of the slider body. A first slide rod is slidably connected to both sides of the end cap. An anti-collision head is fixedly connected to the outer end of the first slide rod. The anti-collision head and the end cap are elastically connected by a first spring. A limit block two is fixedly connected to the other end of the first slide rod. The limit block two is located inside the first slide rod. A steel ball is installed inside the slider body.

[0008] Preferably, a second slide rod is slidably connected to both sides of the slider body. A limit block and a movable block are respectively fixedly connected to the two ends of the second slide rod. The movable block is located inside the slider body, and the limit block is located outside the slider body. The limit block and the outer wall of the slider body are elastically connected by a second spring.

[0009] Preferably, a groove is provided on one side of the movable block, and an inclined block is fixedly connected to the side of the limiting block away from the first sliding rod, and the inclined block is adapted to the groove.

[0010] Preferably, a rubber pad is installed on the side of the movable block away from the second slide bar.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention can buffer and brake the slider. When the sliding movement is obstructed, the anti-collision head installed at the end of the slider contacts the obstruction in advance. Then, the anti-collision head is forced to drive the first sliding rod to retract into the inside of the slider, thereby achieving a buffering effect, effectively protecting the slider and improving the service life of the steel ball. At the same time, when the first sliding rod slides, it drives the inclined block to move. The inclined block squeezes the inclined groove and drives the movable block to slide, so that the rubber pad on the side of the movable block contacts the side of the guide rail, realizing the slider locking and braking, preventing the slider from sliding, and thus further protecting the slider.

[0023] Please see Figure 1-2 The present invention provides a technical solution for a linear guide slider with a buffer function: it includes a slider body 1, with end caps 2 installed at both ends of the slider body 1, and first slide rods 3 slidably connected to both sides of the end caps 2. Anti-collision heads 5 are fixedly connected to the outer ends of the first slide rods 3, and the anti-collision heads 5 and the end caps 2 are elastically connected by a first spring 4. The other end of the first slide rod 3 is fixedly connected to a second limit block 12, which is located inside the first slide rod 3. A steel ball 6 is installed inside the slider body 1.

[0024] The two sides of the slider body 1 are slidably connected to the second slide rod 9. The two ends of the second slide rod 9 are respectively fixedly connected to the limit block 8 and the movable block 11. The movable block 11 is located inside the slider body 1, and the limit block 8 is located outside the slider body 1. The limit block 8 and the outer wall of the slider body 1 are elastically connected by the second spring 7.

[0025] A sloping groove 10 is provided on one side of the movable block 11, and a sloping block 13 is fixedly connected to the side of the limiting block 12 away from the first sliding rod 3. The sloping block 13 is adapted to the sloping groove 10.

[0026] A rubber pad 14 is installed on the side of the movable block 11 away from the second slide bar 9, which provides greater friction and a more secure locking.

[0027] In practical use, this utility model can buffer and brake the slider. When the movement of slider 1 is obstructed, the anti-collision head 5 installed at the end of slider 1 contacts the obstruction in advance. Then, the anti-collision head 5 is forced to drive the first sliding rod 3 to retract into the interior of slider 1, thereby achieving a buffering effect, effectively protecting slider 1 and improving slider service life. At the same time, when the first sliding rod 3 slides, it drives the inclined block 13 to move. The inclined block 13 squeezes the inclined groove 10 to drive the movable block 11 to slide, so that the rubber pad 14 on the side of the movable block 11 contacts the side of the guide rail, realizing slider locking and braking, preventing slider from sliding, thereby further protecting slider.

[0028] The above description is merely a preferred embodiment of this utility model and does not limit the scope of protection of this utility model.
