The guide shaft support seat plays a key role in supporting and positioning the guide shaft in various mechanical devices. Its correct installation is crucial for the stable operation of the mechanical system. The following is a detailed introduction to the installation of the guide shaft support seat
Preparation before installation
Confirm the model specifications: carefully check whether the model and size of the guide shaft support seat and the guide shaft match, and ensure that all parts are complete, including the support seat body, connecting bolts, gaskets, sealing rings, etc.
Check the quality of parts: comprehensively check the appearance of the support seat to check whether there are any damage, defects, burrs, etc. At the same time, measure the diameter, length and other dimensions of the guide shaft to ensure that its matching accuracy with the support seat meets the requirements.
Prepare installation tools: prepare the tools required for installation, such as hexagonal wrenches, torque wrenches, levels, sandpaper (if necessary), etc.
Clean the work area: clean the installation site to ensure that the work area is clean and tidy, free of dust, debris and oil, so as not to affect the installation accuracy and connection stability
Determine the installation position
According to the design requirements: according to the mechanical design drawings or actual work needs, accurately determine the installation position of the support seat on the installation base. Use a marking tool to clearly mark the center line and contour line of the mounting hole.
Consider load and maintenance: The selected installation position should enable the guide shaft support seat to bear the load evenly and facilitate subsequent maintenance, inspection and replacement work. For example, avoid installing the support seat in a small space that is difficult to access.
Install the support seat
Place and align: Place the guide shaft support seat steadily in the predetermined installation position. If it is a flange-type guide shaft support seat, the flange surface must be tightly fitted and aligned with the mounting surface to ensure that the sealing surface of the flange is flat; for open-type guide shaft support seats, ensure that the opening direction is consistent with the movement direction of the guide shaft.
Insert bolts and tighten initially: Insert the connecting bolts into the corresponding holes of the support seat and the mounting base, and use a wrench to gently tighten the bolts for initial tightening, but do not tighten them completely to facilitate subsequent adjustments. During the tightening process, use a level to continuously check the horizontality and verticality of the support seat. If there is any deviation, adjust it in time.
Install the guide shaft
Insert the guide shaft: Insert the guide shaft slowly and steadily into the hole of the support seat. When inserting, be careful to keep the axis of the guide shaft coincident with the axis of the support seat hole to avoid tilting, jamming, etc. If the guide shaft encounters resistance when inserting, do not force it in. You can use sandpaper to lightly grind the surface of the guide shaft to reduce friction, but pay attention to the grinding force to avoid affecting the accuracy of the guide shaft
Adjustment and fixation
Recheck the accuracy: After installing the guide shaft, use measuring tools (such as a level, dial indicator, etc.) to check the straightness of the guide shaft and the installation accuracy of the support seat again to ensure that it meets the design requirements. If necessary, you can make fine adjustments by adding or removing gaskets or fine-tuning the position of the support seat.
Tighten the bolts evenly: Use a torque wrench to tighten all connecting bolts evenly in the specified order and torque. Usually, the tightening sequence is to gradually proceed from the center to the outside to ensure that the support seat and the installation surface are evenly compressed to avoid excessive local stress or deformation of the support seat.
Lubrication and protection
Apply lubricant: Apply an appropriate amount of lubricant, such as lubricating oil or grease, to the contact area between the guide shaft and the support seat to reduce friction and wear and improve the smoothness of the movement of the guide shaft. When applying, follow the product instructions of the lubricant to ensure even application.
Install protective devices: In order to prevent dust, impurities, etc. from invading the interior of the support seat and affecting its performance and life, it is necessary to install corresponding protective devices, such as protective covers, dust covers, etc.
