Description

Technical Field

[0001] This utility model relates to the field of linear guide technology, and in particular to a linear guide with a locking structure. Background Technology

[0002] Linear guides are mechanical transmission components with high-precision slide rails and sliding sliders as their core structure. They are mainly used to support and guide moving parts. By reducing frictional resistance through rolling or sliding contact between the slide rail and the slider, they can ensure positioning accuracy, guiding accuracy, and system rigidity during movement. Most current linear guides do not have a locking mechanism, which means that they cannot be effectively locked when it is necessary to fix the position of moving parts. This can cause unnecessary displacement of the slider due to external forces during the stopping process.

[0003] In the prior art, a linear guide rail with a locking structure is disclosed. The locking mechanism, which consists of an electric push rod, a locking push plate, a locking rack, and a locking pressure plate, can lock and fix the slider at different positions on the guide rail body according to actual needs.

[0004] However, it still has certain limitations in practical applications. Its locking mechanism relies on electric drive and does not have a self-locking function. Once a power outage or other power interruption occurs, the core locking function will immediately fail. This not only makes it difficult to ensure the stability of the slider position when the machine is stopped, but may also cause safety risks due to the accidental movement of the slider. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, the purpose of this utility model is to propose a linear guide rail with a locking structure. Through the design of the automatic locking mechanism, the slider can be automatically locked in the event of power failure or gas failure, so as to avoid unnecessary displacement of the slider and improve safety and stability.

[0007] To achieve the above objectives, this utility model proposes a linear guide rail with a locking structure, comprising a slide rail, a slider, a locking mechanism, and a driving assembly. The slide rail has equidistant mounting holes. The slider is slidably disposed outside the slide rail and can be adjusted along the length of the slide rail. The locking mechanism is disposed on the slider and includes two sets of contact components, two sets of pressing components, and a mounting base. The two sets of contact components are symmetrically disposed within the mounting base and symmetrically fitted to both sides of the slide rail. The two sets of pressing components are disposed at the ends of the two sets of contact components. The driving assembly is disposed on the mounting base, and its two air outlets are connected to the two sets of contact components.

[0008] In addition, the linear guide rail with locking structure proposed above according to this utility model may also have the following additional technical features: Specifically, each set of contact components includes a locking seat, a drive rod, a piston, and a piston cylinder, wherein one end of the drive rod is connected to the locking seat, the other end of the drive rod is located inside the piston cylinder and connected to the piston, and the piston is slidably disposed inside the piston cylinder.

[0009] Specifically, each clamping assembly includes a connecting rod, a retaining ring, an elastic element, and an adjusting head. The retaining ring is disposed on the connecting rod, the adjusting head is sleeved on the outside of the connecting rod and has a clamping part at its end, and the elastic element is sleeved on the connecting rod and its two ends abut against the retaining ring and the clamping part, respectively.

[0010] Specifically, the drive assembly includes two connecting pipes, two air pipes, and a solenoid valve, wherein the two connecting pipes are connected to the air outlet of the solenoid valve through the two air pipes.

[0011] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects: This utility model, by setting up a locking mechanism, utilizes the cooperation of the pressing component and the contact component to automatically lock the slider under the action of the elastic element in the event of unexpected situations such as power failure or gas failure. This effectively prevents the slider from causing unnecessary displacement due to external forces, improving safety and stability. Moreover, the clamping force of the locking seat on the slide rail can be easily adjusted by the adjusting head, thereby meeting the requirements of the slider locking force under different working conditions and enhancing the overall applicability and flexibility.

Detailed Implementation

[0015] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0016] The following describes a linear guide rail with a locking structure according to an embodiment of the present invention, with reference to the accompanying drawings.

[0017] like Figures 1-6 As shown, a linear guide rail with a locking structure according to an embodiment of the present invention includes a slide rail 1, a slider 3, a locking mechanism and a drive assembly 7. The slide rail 1 is provided with mounting holes 2 at equal intervals. The slider 3 is slidably disposed outside the slide rail 1 and can be adjusted along the length direction of the slide rail 1. The locking mechanism is disposed on the slider 3.

[0018] It should be noted that the evenly distributed mounting holes 2 facilitate the stable installation of the slide rail 1. The shape of the slider 3 is adapted to the shape of the slide rail 1 to ensure that the slider 3 can slide smoothly along the length of the slide rail 1 without tilting or falling off. The locking mechanism can lock the position of the slider 3 to ensure that the slider 3 can remain stable when it needs to be fixed, and avoid unnecessary displacement due to external forces.

[0019] The locking mechanism includes two sets of contact components 5, two sets of pressing components 6, and a mounting base 4. The two sets of contact components 5 are symmetrically arranged in the mounting base 4 and symmetrically attached to both sides of the slide rail 1. The two sets of pressing components 6 are arranged at the ends of the two sets of contact components 5. The drive component 7 is arranged on the mounting base 4, and its two air outlets are connected to the two sets of contact components 5.

[0020] It should be noted that the two sets of contact components 5 are symmetrically attached to both sides of the slide rail 1, and can clamp the slide rail 1 from both sides under the action of the corresponding clamping components 6, thereby locking and fixing the slider 3. The drive component 7 provides unlocking power for the locking mechanism, and transmits gas pressure to the contact component 5 through the two air outlets, so that the contact component 5 is separated from the slide rail 1, thereby allowing the slider 3 to slide along the slide rail 1.

[0021] In one embodiment of this utility model, such as Figures 4-5 As shown, each contact assembly 5 includes a locking seat 51, a drive rod 52, a piston 53, and a piston cylinder 54. One end of the drive rod 52 is connected to the locking seat 51, and the other end of the drive rod 52 is located inside the piston cylinder 54 and connected to the piston 53. The piston 53 is slidably disposed inside the piston cylinder 54.

[0022] It should be noted that the mounting base 4 has a corresponding mounting cavity for mounting the locking seat 51 and the piston cylinder 54. The locking seat 51 is slidably disposed in the mounting cavity, and the end of the drive rod 52 away from the piston 53 is located outside the piston cylinder 54, and its outer wall is in contact with the piston cylinder 54, thereby ensuring the airtightness of the entire piston structure.

[0023] Specifically, when the drive assembly 7 fills the piston cylinder 54 with gas through the gas outlet, the piston 53 slides along the inside of the piston cylinder 54 under the action of gas pressure, thereby driving the drive rod 52 and the locking seat 51 to move, so that the locking seat 51 separates from the slide rail 1. At this time, the slider 3 can slide freely on the slide rail 1. When the drive assembly 7 stops filling with gas or there is a power outage or gas outage, the piston 53 resets under the action of the clamping assembly 6, and the locking seat 51 re-fits against both sides of the slide rail 1, thereby realizing the automatic locking and fixing of the slider 3.

[0024] In one embodiment of this utility model, such as Figures 4-5 As shown, each clamping assembly 6 includes a connecting rod 61, a retaining ring 62, an elastic element 63, and an adjusting head 65. The retaining ring 62 is disposed on the connecting rod 61, the adjusting head 65 is sleeved on the outside of the connecting rod 61, and its end is provided with a clamping part 64. The elastic element 63 is sleeved on the connecting rod 61, and its two ends abut against the retaining ring 62 and the clamping part 64, respectively.

[0025] It should be noted that the retaining ring 62 is fixed to the outer wall of the connecting rod 61, and the adjusting head 65 is a hollow structure with a hexagonal through groove inside and a thread on the outer wall, which cooperates with the threaded hole on the mounting base 4. The retaining ring 62 is slidably disposed in the mounting cavity. The elastic element 63 is a spring. When the spring pushes the retaining ring 62, the retaining ring 62 pushes the piston 53 through the connecting rod 61. The piston 53 pushes the locking seat 51 through the driving rod 52, so that the locking seat 51 is in close contact with the slide rail 1, thereby locking the slider 3.

[0026] Understandably, when it is necessary to adjust the clamping force of the locking seat 51 on the slide rail 1, the adjusting head 65 is rotated clockwise using a hex screwdriver. Since the adjusting head 65 is threadedly connected to the mounting seat 4, it will move along the axial direction of the connecting rod 61 during rotation, thereby changing the compression of the elastic element 63. The elastic element 63 is further compressed, and the elastic force it generates will also increase. This elastic force is transmitted to the piston 53 through the retaining ring 62 and the connecting rod 61, ultimately enhancing the clamping force between the locking seat 51 and the slide rail 1 to meet the requirements of the locking force of the slider 3 under different working conditions.

[0027] In one embodiment of this utility model, such as Figures 2-4 As shown, the drive assembly 7 includes two connecting pipes 71, two air pipes 72, and a solenoid valve 73. The two connecting pipes 71 are connected to the air outlet of the solenoid valve 73 through the two air pipes 72.

[0028] It should be noted that the solenoid valve 73 is a normally closed two-position three-way valve with an internal solenoid coil. The opening and closing of the air passage is controlled by energizing or de-energizing the solenoid coil. The air inlet of the solenoid valve 73 is connected to an external high-pressure air source. The end of the connecting pipe 71 away from the air pipe 72 is fixedly connected to and communicates with the piston cylinder 54. The piston cylinder 54 is provided with an exhaust pipe (not shown in the figure) that communicates with the solenoid valve 73. Thus, when the power is off, the piston cylinder 54 can communicate with the atmosphere and discharge the gas inside the piston cylinder 54. The solenoid valve 73 is mounted on the mounting base 4 and is used to control the unlocking operation of the contact component 5.

[0029] Specifically, when the solenoid valve 73 is energized, gas enters from the inlet and is delivered to the two piston cylinders 54 through the two outlets via the two air pipes 72 and the two connecting pipes 71, causing the piston 53 to move under the action of gas pressure, thereby driving the locking seat 51 to separate from the slide rail 1 and unlocking the slider 3; when the solenoid valve 73 is de-energized, the air circuit is closed, and under the action of the elastic element 63, the piston 53 resets, and the locking seat 51 re-fits the slide rail 1, thereby locking the slider 3.

[0030] In practical applications, when slider 3 needs to be moved, solenoid valve 73 is energized. Gas is delivered to the two piston cylinders 54 through two air pipes 72 and two connecting pipes 71. Under the action of gas pressure, piston 53 slides along the inside of piston cylinder 54, driving drive rod 52 and locking seat 51 to move, causing locking seat 51 to separate from slide rail 1. At this time, slider 3 can slide freely on slide rail 1. When slider 3 moves to the desired position, solenoid valve 73 is de-energized. The electromagnetic coil inside solenoid valve 73 is de-energized, the air passage is closed, and under the action of elastic element 63... The locking seat 51 re-fits onto both sides of the slide rail 1, thereby locking and fixing the slider 3, ensuring that the slider 3 can remain stable when it needs to be fixed. When it is necessary to adjust the clamping force of the locking seat 51 on the slide rail 1, the adjusting head 65 can be rotated clockwise with a hex screwdriver. During the rotation, the adjusting head 65 will move along the axial direction of the connecting rod 61, thereby changing the compression of the elastic element 63. The elastic element 63 is further compressed, ultimately increasing the clamping force between the locking seat 51 and the slide rail 1 to meet the requirements of the locking force of the slider 3 under different working conditions.

[0031] In summary, the linear guide rail with a locking structure of this utility model, by setting a locking mechanism and utilizing the cooperation of the pressing component and the contact component, can automatically lock the slider under the action of the elastic element in the event of unexpected situations such as power failure or gas failure. This effectively prevents the slider from causing unnecessary displacement due to external forces, improving safety and stability. Moreover, the clamping force of the locking seat on the slide rail can be easily adjusted by the adjusting head, thereby meeting the requirements of the slider locking force under different working conditions and enhancing the overall applicability and flexibility.
