Linear optical axis function, structural characteristics and technical requirements of linear axis is one of the typical machine parts often encountered. It is mainly used to support transmission parts, transmission torque and load bearing. Linear optical axis is a rotating body parts, its length is greater than the diameter, generally by the outer cylindrical, conical surface, the hole and the thread and the corresponding end surface composed of concentric shafts. Depending on the shape of the structure, linear axis can be divided into chrome rods, stepped shaft, hollow shaft and the crank. The optical axis is called the short axis aspect ratio of less than 5, greater than 20 is called an elongated shaft, the shaft between the two most. Optical axis with the bearing, shaft and bearing with section referred to as the journal. The journal is mounting reference axis linear slide Foshan, their accuracy and surface quality in general higher, its main function is generally based on technical requirements and working conditions shaft development, Dongguan linear slide, generally have the following :( a) play supporting role in the dimensional accuracy of the journal in order to determine the position of the shaft, its size is usually higher precision (IT5 ~ IT7). Journal size precision assembly of transmission parts generally require lower (IT6 ~ IT9). (B) the geometry of precision geometry precision linear optical axis mainly refers to the journal, outer cone, like Morse taper bore roundness, cylindrical, etc., generally should be limited within the tolerance range of dimensional tolerance. For high precision internal and external circular surface, which should be marked on the drawing tolerances. (C) the mutual position accuracy precision linear axis position is mainly required by the mechanical axis position and function of the decision. It should normally ensure transmission parts for assembly journal bearing journal of concentricity requirements, the robot linear slide, otherwise it will affect transmission parts (gear, etc.) in driving accuracy, and noise. Ordinary precision shaft, which shaft section with radial runout bearing journal is generally 0.01 ~ 0.03mm, high precision axis (spindle) is generally 0.001 ~ 0.005mm. Comparison and analysis of three well-known types of machine tools rails, the contact area of ??linear rails, flat between the rails and the moving element is relatively large, the moving element to make rapid micro feed. To overcome the inertia of the moving element, and therefore will have a creeping phenomenon. When the ball screw or other driving force of the moving element is moved, produces a slight adhesion resistance, the moving element begins to move, the moving element is in a state of being caught, there has been a slight beating, resulting in crawling, This phenomenon is not for moving high-impact, and for trace movement, has become a problem. tunability is a unique advantage flat rail, according to the use of rail, flat rail system has at least one or more adjustable side Since the movable member to move along a linear guide side, moving to ensure intimate contact with the side rail member is extremely important. The method is commonly used between the adjustment wedges, wedges located on the movable member and the guide rail opposite the contact surface side. conical shape angle iron bar, can be precisely adjusted to eliminate the gap between the moving parts and the rail. If the gap sliding member or rail wear, increasing the contact surface between the adjustable wedges to compensate. Machine Manufacturing Factory has invented a wedge-patented technology to automatically adjust its basic principle is to maintain a fixed wedges spring pressure, once the rail system is worn wedges can automatically eliminate the gap between the moving parts and the rail linear slide , cpc miniature linear slide, Korea and Taiwan transmission machinery (certified merchants) provided by the Dongguan City, Transmission Machinery Co., Ltd. of Korea and Taiwan.
