Description
Technical Field
[0001] This utility model belongs to the field of linear guide technology, and in particular relates to an assemblable linear guide structure. Background Technology
[0002] Linear guides are widely used in various manufacturing equipment, machine tools, semiconductor and display panel production equipment, robotic systems, logistics automation facilities, and precision measuring instruments to achieve high-precision linear motion. Over 70 years ago, linear guide technology emerged under conditions of limited machining precision. At that time, machining relied primarily on general-purpose machine tools and the experience of skilled workers, thus requiring an installation tolerance of approximately ±0.5mm. In this context, to adjust straightness and parallelism on-site, traditional installation methods maintained a gap of approximately 1mm between the guide rail fixing bolt holes and the guide rail body. However, with this structure, after tightening the bolts, the guide rail only adheres tightly to a specific area on the bottom surface. When there is an impact on the side or a load exceeding the adhesion force of that area, the guide rail is prone to displacement, making it difficult to guarantee the overall machine accuracy. To improve this problem, traditional methods often involve creating steps on the side of the guide rail or machining grooves of the same width as the guide rail on the bottom, using side clamping components to apply lateral pressure and fix the guide rail. While this method is an improvement, it still requires additional step or groove machining, additional parts, highly skilled workers, and a longer assembly time, increasing cost and complexity. The 1mm gap method, which has been used for 70 years, is outdated and inefficient in modern industry. Today, with the development of CNC machining technology, the precision of base machining and tapping can easily reach ±0.1mm or even ±0.02mm. However, the traditional installation concept has not been updated, resulting in the continued use of outdated large gaps and complicated processes during on-site installation, causing unnecessary waste of time, cost and manpower.
[0003] Existing linear guides are widely used in semiconductor and display panel production lines, precision machining equipment, robots, and various automated equipment. Traditional mounting methods typically employ a stepped shoulder structure. This is achieved by machining a stepped structure onto the guide mounting base and using side-press-in components for additional fixation, thereby ensuring the structural stability of the guide under high-speed movement, external vibration, and impact conditions.
[0004] However, this traditional method has the following problems:
[0005] 1. High processing cost: Manufacturing precision stepped shoulder structures requires additional precision machining processes and time, which significantly increases production costs.
[0006] 2. Complex installation: Additional press-fit parts, bolts, etc. are required, which increases the assembly steps and time.
[0007] 3. Lack of flexibility in certain specific working conditions: The application of this method is limited in scenarios where space is limited or rapid installation is required.
[0008] Therefore, how to reduce processing costs and simplify assembly processes while ensuring structural stability and precision has become a topic of concern in the industry. Summary of the Invention

[0155] An assemblable linear guide structure, the installation method of which includes the following steps:
[0156] Step F1: Using CNC machining, precisely control a tiny offset of about 0.3mm when tapping the sixth mounting hole 33 on the mounting table 2 and the sixth countersunk groove 32 on the guide rail 1, and the offset tends to the convex side of the mounting table 2.
[0157] Step F2: Make one side of the guide rail 1 contact the protrusion of the mounting platform 2, and screw the mounting bolt 3 into the sixth recess 32 of the guide rail 1 and into the sixth mounting hole 33 on the mounting platform 2.
[0158] Step F3: After the mounting bolts 3 are tightened, the guide rail 1 will automatically shift slightly in the predetermined direction and fit against the protrusion of the mounting platform 2, achieving self-correction and stable fixation without additional parts, thus fixing the guide rail 1.
[0159] Example 7
[0160] like Figures 19 to 21 As shown in the figure, the present invention provides an assemblable linear guide structure, including a guide rail 1, the two sides of the guide rail 1 being R-shaped, a mounting platform 2 for installation being provided at the bottom of the guide rail 1, and a mounting bolt 3 for limiting and fixing being provided at the top of the guide rail 1.

[0164] For devices requiring extremely high precision, specially made bolts with a concentricity of ±0.02mm can be used to meet stringent installation accuracy requirements.
[0165] When the bolt is tightened, the taper of the bolt head and the fit with the hole naturally guide the guide rail 1 to be precisely positioned, achieving automatic centering and fixation of the guide rail 1 without the need for side clamping components.
[0166] An assemblable linear guide structure, the installation method of which includes the following steps:
[0167] Step G1: When the installation of guide rail 1 needs to be simplified, the seventh countersunk groove 34 on guide rail 1 is initially aligned with the seventh mounting hole 35.
[0168] Step G2: Pass the mounting bolt 3 through the seventh countersunk groove 34 and screw it into the seventh mounting hole 35;
[0169] When tightening the mounting bolt 3 in step G3, the conical surface of the mounting bolt 3 head and the seventh recess 34 will naturally guide the guide rail 1 to be accurately positioned, and the guide rail 1 can be automatically centered and fixed without the need for side clamping components.
