Linear guide and ball screw contrast
Positioning accuracy: In terms of accuracy, the identification of linear guide transmission mechanism reduces the problem of interpolation lag, positioning accuracy, reproduction accuracy, and feedback control through position detection will be easier to achieve than rotary motor ball screw.
How to choose the right linear guide?
The function of the linear guide is to support and guide the moving parts, and to perform reciprocating linear motion in a given direction. In order to apply the right type of linear guide to the right situation, it is necessary for the design engineer to understand the advantages and capabilities of different guides, so as to make a reasonable choice.
Installation method of linear slide
1. Clean up the dirt on the assembly surface of the bed table. 2. Place the linear slide rail on the bed table smoothly, and let the reference surface of the side of the slide rail rest against the assembly surface of the bed table. 3. Try to lock the assembly screws to confirm whether the bolt holes match, and roughly fix the reference surface at the bottom of the slide rail to the assembly surface at the bottom of the bed.
Precautions in the use of linear guide
The use of linear guide belongs to the precision parts, so in use requires a very cautious attitude, even if the use of high-performance linear guide, if used improperly, can not achieve the desired performance effect, and easy to damage the linear guide.
What is the processing process of linear slider?
The linear slider is a general-purpose component that completes precise feed motion and complex multi-station working cycle motion. According to the technological requirements of the processed parts, it can be equipped with sensory power components to complete drilling, reaming, boring, tapping, chamfering, scraping, etc., and can input linear motion coordinates, with the characteristics of accurate movement. It is suitable for the rainproof, dustproof and windproof of the conveyor belt of power plants, cement plants, coal mines and other major mining enterprises. The loss of goods is reduced during the transmission process, so that the conveyor belt is more safe and reliable in operation, and it plays a greater role in purifying the environment.
Sliding principle of linear guide
In practical application, for the principle of this linear guide, there are still most customers can not clearly understand. A few days ago, a customer called to inquire about what the slider of the linear guide rail slides and how it slides. In fact, there are two rows of beads in the slider of the linear guide rail. The reason why it can slide is from the movement on both sides of the beads. However, it is really necessary to subdivide it into silent type and unsilent type. The two types are respectively applied to different mechanical equipment.
Precision linear guide installation design principles
Precision principle of non-interference in the manufacture and use of the precision of the guide rail does not affect each other to easily get higher precision. For example, the straightness of the rectangular guide rail and the straightness of the side guide rail do not affect each other during manufacturing; the change of the transverse dimension of the flat-V guide rail will not affect the working accuracy of the guide rail.
The rotating guide rail is characterized by low friction resistance, light and flexible movement; small wear and tear, can maintain long-term accuracy; dynamic and static friction coefficient difference is small, low speed is not easy to appear "crawling" phenomenon, so the movement is uniform and stable. Therefore, the rotating guide rail is increasingly widely used in the equipment requiring micro-movement and precise positioning. The disadvantages of the rotating guide rail are: the guide rail surface and the rotating body are in point contact or line contact, poor vibration resistance and large contact stress, so the surface hardness of the guide rail is required to be high: the shape accuracy of the guide rail and the dimensional accuracy of the rotating body are required to be high.
What are the reasons for the linear guide being strongly respected?
Whether it is from the structure or from the accuracy of the linear guide above, in fact, can be adjusted, that is, its operating speed of such parameters can be adjusted and selected. Therefore, the corresponding model can be selected according to the specific situation of the machine tool.
