Description

Technical Field

[0001] The utility model relates to the technical field of roller chain belt linear guide rail pairs, in particular to roller chain belt linear guide rail pairs. Background Art

[0002] Roller chain linear guides are a key component widely used in modern industrial automation and precision machinery. They are mainly used to achieve high-precision linear motion and positioning. This guide pair usually consists of a slider and a roller chain assembly, where the slider moves along a fixed guide rail and the roller chain is responsible for transmitting force and motion. The application range of roller chain linear guides is very wide, including CNC machine tools, automated assembly lines, robotics, precision measuring equipment, etc.

[0003] However, the existing roller chain linear guide pair has some shortcomings:

[0004] Installation complexity: Traditional roller chain linear guide pairs often require precise calibration and alignment during the installation process, especially the traditional roller chain linear guide pair. The internal roller chain assembly is a split design. This design is to adapt to the internal installation structure of the traditional slider. In particular, the rollers in the traditional roller chain assembly need to be inserted into the chain one by one, which is not only time-consuming, but also requires high skills of the operator, increasing the complexity and cost of installation.

[0005] Difficult maintenance: Due to the close fit between components, once a failure occurs or maintenance is required, the disassembly and reassembly process may be very cumbersome, resulting in long maintenance cycles and affecting production efficiency.

[0006] Therefore, this invention proposes a roller chain linear guide pair to solve the above problems. Utility Model Content

[0007] In order to overcome the defects of the prior art, the utility model aims to provide a roller chain linear guide pair.

[0008] To achieve the above object, the technical solution of the utility model is implemented as follows: a roller chain linear guide pair, including a slider and a roller chain assembly, the left and right side walls of the guide rail penetration hole inside the slider are provided with cross mounting guide grooves, the roller chain assembly is inserted corresponding to the tail end port of the cross mounting guide groove, the front end of the slider is fixedly installed with a fixed end cover, the tail end port of the slider is provided with a T-shaped vertical clamping tooth near the left and right sides, the tail end of the slider is provided with a movable end cover, and the inner end surface of the movable end cover is provided with a T-shaped docking groove adapted to the T-shaped vertical clamping teeth on both sides near the left and right sides;

[0009] The roller chain belt assembly specifically includes the following structure:

[0010] Two cross-distributed roller chains;

[0011] End locating seats installed at the front and rear ends of two roller chains;

[0012] A front end positioning column distributed at the front end center of the end positioning seat;

[0013] Positioning protruding teeth in the shape of a rectangular parallelepiped and distributed vertically at the rear end center of the end positioning seat at the rear end;

[0014] The inner end surface of the fixed end cover is provided with two positioning holes adapted to the front end positioning seats at the front ends of the roller chain belt assemblies on both sides;

[0015] The inner end surface of the movable end cover is provided with two vertically distributed positioning slots, and the positioning slots on both sides are respectively matched with the positioning protruding teeth on both sides.

[0016] Preferably, the T-shaped docking slot runs through the upper and lower ends of the entire movable end cover.

[0017] Preferably, the positioning slot runs through the upper and lower ends of the entire movable end cover.

[0018] Preferably, a bottom support platform extending toward the rear end is provided at the bottom of the tail end of the slider, and the top of the bottom support platform is supported on the bottom of the movable end cover.

[0019] Preferably, the movable end cover and the rear end surface of the slider are further limited by a plurality of butt bolts.

[0020] The beneficial effects of the utility model are embodied in:

[0021] High precision and stability: The precisely designed cross mounting guide and positioning holes ensure the accurate installation of the roller chain assembly in the slider, thus providing high-precision linear motion. The precise matching of the fixed end cover and the movable end cover further enhances the stability of the system.

[0022] Easy to assemble and maintain: The assembly steps are clear, and the roller chain assembly and movable end cover can be installed by simple insertion and snap-in operations, reducing installation time and difficulty. In addition, the modular design makes maintenance and replacement of parts easier.

[0023] Flexible positioning and adjustment: The T-shaped docking slot and positioning slot design of the movable end cover make the roller chain assembly easy to position.

[0024] Safety design to prevent detachment: The movable end cover is fixed to the rear end face of the slider by docking bolts, which effectively prevents the movable end cover from accidentally detaching during operation and increases the safety and reliability of the system.

[0025] In summary, the roller chain linear guide pair provides an efficient, stable and easy-to-maintain solution through its careful design and optimized assembly process. BRIEF DESCRIPTION OF THE DRAWINGS
