Description

Technical Field

[0001] This utility model relates to the field of linear guide technology, specifically a linear guide with a locking device. Background Technology

[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. Based on the nature of friction, linear motion guides can be classified into sliding friction guides, rolling friction guides, elastic friction guides, and fluid friction guides. Linear guides are commonly used in industrial machinery to ensure the smooth movement of parts or tools on linear tracks. They are typically made of metal or plastic and have a highly flat surface to reduce friction and improve precision. Currently, during the use of linear guides, the sliding sleeves equipped with the linear guides move horizontally on the linear guide. The sliding sleeves are positioned as needed for operation. However, some sliding sleeves stop during movement on the linear guide, resulting in a brief period of inertial sliding, which causes a certain positional deviation. During operation, even a slight positional deviation can have a significant impact on the quality of the entire production process. Linear guides with linear locking effects are particularly important. Linear guides that cannot meet this condition have reduced performance and directly affect the stability of the linear guide's trajectory position.

[0003] Therefore, it is necessary to develop a linear guide with a locking device. Utility Model Content

[0004] The purpose of this utility model is to provide a linear guide rail with a locking device. Anti-slip strips A and B are provided. Anti-slip strip A is positioned at the center of the linear guide rail surface, and anti-slip strip B is positioned at the bottom of the pressure plate. The limiting post on the pressure plate is spring-loaded and kept in a reset state. When the sliding sleeve moves normally, the pressure plate and the linear guide rail maintain a certain distance due to the spring restriction. When the sliding sleeve stops moving, the electric push rod inside the U-shaped frame pushes the top block until anti-slip strip B on the pressure plate contacts anti-slip strip A, thus locking the sliding sleeve position. This effectively prevents brief inertial sliding during the sliding sleeve's movement, significantly improving the performance and stability of the linear guide rail. This solves the problem of poor linear guide rail performance affecting its use and stability mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a linear guide rail with a locking device, comprising a base plate, a linear guide rail mounted on the top of the base plate, and a sliding sleeve mounted on the outer wall of the linear guide rail;

[0006] U-shaped brackets are installed on both sides of the bottom of the sliding sleeve.

[0007] Preferably, an anti-slip strip A is provided at the center of the upper surface of the linear guide rail.

[0008] Preferably, a groove is formed below the surface of the sliding sleeve, and the inner wall of the groove is slidably connected to the outer wall of the linear guide rail.

[0009] Preferably, a support column is provided at both the top and bottom of the groove, and a ball bearing is rotatably connected to one end of the support column.

[0010] Preferably, a mounting hole is provided at the center of the surface of the U-shaped frame, and a limit post is installed inside the mounting hole.

[0011] Preferably, the outer wall of the limiting post is slidably connected to the inner wall of the mounting hole, one end of the limiting post is provided with a limiting ring, and the other end of the limiting post is provided with a pressure plate.

[0012] Preferably, a spring is provided on the upper part of the outer wall of the limiting post, and an anti-slip strip B is provided on the bottom of the pressure plate.

[0013] Preferably, an electric push rod is installed at the center of the U-shaped frame, and a top block is installed at the output end of the electric push rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By incorporating anti-slip strips A and B, with anti-slip strip A positioned at the center of the linear guide surface and anti-slip strip B at the bottom of the pressure plate, the limiting post on the pressure plate is spring-loaded and kept in a reset state. During normal movement of the sliding sleeve, the pressure plate maintains a certain distance from the linear guide under the spring's constraint. When the sliding sleeve stops moving, the electric push rod inside the U-shaped frame pushes the top block until anti-slip strip B on the pressure plate contacts anti-slip strip A, thus locking the sliding sleeve in place. This effectively prevents brief periods of inertial sliding during the sliding sleeve's movement, significantly improving the performance and stability of the linear guide.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides the following technical solution: a linear guide rail with a locking device, please refer to... Figure 1-5 The system includes a base plate 1, a linear guide rail 101 mounted on the top of the base plate 1, an anti-slip strip A102 positioned at the center of the upper surface of the linear guide rail 101, and a sliding sleeve 2 mounted on the outer wall of the linear guide rail 101. A groove 201 is formed below the surface of the sliding sleeve 2, and the inner wall of the groove 201 is slidably connected to the outer wall of the linear guide rail 101. The sliding sleeve 2 is slidably mounted on the outer wall of the linear guide rail 101 on the base plate 1 via the groove 201, allowing the sliding sleeve 2 to slide on the outer wall of the linear guide rail 101. The slide sleeve 2 moves horizontally to the left or right. The top and bottom of the groove 201 are provided with support columns 202. One end of the support column 202 is rotatably connected to a ball bearing 203. Several support columns 202 are provided at the top and bottom of the groove 201, and the ball bearing 203 is rotatably connected inside the support column 202. When the support column 202 contacts the end face of the linear guide 101, it supports the slide sleeve 2 on the one hand, and does not affect the normal horizontal movement of the slide sleeve 2 to the left or right on the other hand.

[0024] U-shaped frames 3 are installed on both sides of the bottom of the sliding sleeve 2. A mounting hole 301 is provided at the center of the surface of each U-shaped frame 3. A limiting post 302 is installed inside the mounting hole 301. The outer wall of the limiting post 302 is slidably connected to the inner wall of the mounting hole 301. Two sets of U-shaped frames 3 are installed on the bottom sides of the sliding sleeve 2, and the limiting post 302 is slidably positioned within the mounting hole 301 on the U-shaped frame 3, allowing it to slide vertically up and down on the U-shaped frame 3. A limiting ring 303 is provided at one end of the limiting post 302, and a pressure plate 304 is provided at the other end. The limiting ring 303 and pressure plate 304 are positioned outside and inside the U-shaped frame 3, respectively, to limit the limiting post 302 and prevent it from detaching from the U-shaped frame 3. A spring 305 is installed on the upper part of the outer wall. Utilizing the elasticity of the spring 305, the pressure plate 304 can be kept in the reset state when the spring 305 is unpressurized. An anti-slip strip B306 is installed at the bottom of the pressure plate 304. An electric push rod 307 is installed at the center of the interior of the U-shaped frame 3. A top block 308 is installed at the output end of the electric push rod 307. When the sliding sleeve 2 stops moving, the electric push rod 307 in the U-shaped frame 3 pushes the top block 308 until the anti-slip strip B306 on the pressure plate 304 contacts the anti-slip strip A102, thereby locking the position of the sliding sleeve 2, that is, locking it in place, and minimizing the occurrence of brief inertial sliding when the sliding sleeve 2 stops moving.

[0025] Working Principle: When using this utility model, the sliding sleeve 2 is slidably mounted on the outer wall of the linear guide rail 101 on the base plate 1 via the groove 201, allowing the sliding sleeve 2 to move horizontally to the left or right on the outer wall of the linear guide rail 101. Several support pillars 202 are provided at both the top and bottom of the groove 201, and ball bearings 203 are rotatably connected inside the support pillars 202. When the support pillars 202 contact the end face of the linear guide rail 101, they support the sliding sleeve 2 without affecting its normal left or right horizontal movement. Two sets of U-shaped frames 3 are correspondingly installed on the bottom sides of the sliding sleeve 2, and the limiting post 302 is slidably mounted in the mounting hole 301 on the U-shaped frame 3, allowing the limiting post 302 to slide vertically up and down on the U-shaped frame 3. Limiting rings 303 and pressure plates 304 are sequentially provided at both ends of the limiting post 302. The limiting ring 303 and pressure plate 304 are placed on the outside and inside of the U-shaped frame 3 to limit the limiting post 302, preventing the limiting post 302 from detaching from the U-shaped frame 3. By setting a spring 305 on the outer wall of the limiting post 302, the elastic effect of the spring 305 is utilized to keep the pressure plate 304 in the reset state when the spring 305 is unpressurized. By installing the electric push rod 307 in the center position inside the U-shaped frame 3 and installing a top block 308 on the output end of the electric push rod 307, when the sliding sleeve 2 stops moving, the electric push rod 307 inside the U-shaped frame 3 pushes the top block 308 until the anti-slip strip B306 on the pressure plate 304 contacts the anti-slip strip A102, thereby locking the position of the sliding sleeve 2, that is, locking it. This avoids the situation where the sliding sleeve 2 stops moving and there is a brief inertial sliding, effectively improving the use effect of the linear guide and directly improving the running stability of the linear guide.
