An expansion bolt is a special threaded connector，Its main function is to support the pipeline/hoist/Brackets or devices are fixed to the wall、On the floor。 Expansion bolt before starting to use，An impact drill must be used（hammer）At fixed point（wall、floor）Drill through holes of appropriate size，Then insert the bolt and expansion tube into the hole，Then use the tool to tighten the nut to achieve the bolt、Tube expansion、The mounting kit is tightly fitted to the fixed point。 This section describes how to install an expansion bolt： 1.After drilling the hole at the fixed point, the bolt and expansion tube are smashed into the hole。 2
Mention hinge，Stainless steel hinges must be one of the most common hinges we see in daily life，In the cupboard、Stainless steel hinges are usually installed on wardrobes，So what special attention should be paid to the installation of hardware stainless steel hinges？Here is a brief introduction。 1.Before installing hardware stainless steel hinges，We need to install objects such as doors、Weight of cabinet、Approximate size assessment，Then select the appropriate stainless steel hinge based on the estimated results，Proper hinges ensure normal opening and closing。If an improper hinge is installed，Damage to hinges and mounting objects
Each bearing product with seat will be printed with its brand name on the bearing seat product body、Label etc。Although the font is very small，However, the products produced by regular manufacturers all use steel printing technology，And its pressed before its overheated，So the font is small，But deep concave，Very clear。And as usual，The font of the counterfeit product is not only blurred，Because of the rough printing technique，The font floats on the surface，Some can even be easily wiped away by hand or the handmade marks are severe。 Whether there is a muddy oil stain on the surface requires us to pay special attention when purchasing imported bearing seats。Due to domestic rust prevention
Domestic bearing market‚High-end bearings have been monopolized by imported bearings‚Under the pressure of this situation‚Chinas domestic large bearing production enterprises‚Vigorously develop high-precision bearing series‚So far, good results have been achieved‚The quality of high-precision bearings produced by the domestic Wuxi two-axis has been tested by the state to replace imported bearings‚And has a considerable price advantage。here‚This paper introduces the difference between imported bearings and domestic bearings。1、The difference of models comes with the advent of internationalization‚Domestic bearing codes are gradually integrated with imported bearing codes‚Newly published national standards show‚Domestic code and internationalISOBasically consistent standards。
The life cycle extension method of bearings is divided into five points，①Basic condition monitoring；②Bearing installation；③alignment,straightening；④relubrication；⑤Unequip。 ①Basic condition monitoring During use,The basic external conditions of bearing operation should be monitored frequently,For example, temperature,Vibration and noise measurement, etc。These regular checks will detect potential problems early and will prevent unexpected machine outages，Enable the production plan to be realized,Increased factory productivity and efficiency。 ②Bearing installation Whether the bearings are installed correctly，influence
Do you usually install ball screws？So are you installing it in the right way？Then please follow the editor to take a look below！ First of all, we must first understand the common installation method of ball screw。 The first kind：Lead screw fixation、Nut rotation mode Turn the nut on one side、One side moves axially along a fixed lead screw。Low nut inertia、Flexible movement，High speed achievable，Because the lead screw is not moving，It can avoid all kinds of problems that occur when the slender ball screw is running at high speed and the problem that is limited by the critical speed。In this way, a large pre-pull can be applied to the ball screw
Ball screw noise caused，There are generally several factors。 1、The ball screw surface has been used for a long time，The surface of the steel ball is peeling，Or the lead screw shaft cutting force surface has the same problem，The steel ball cannot be used smoothly across the track，Causes the nut and shaft to vibrate before，Make a noise。 2、Cooperate through slack，After a long time of use, the nut and screw of the ball screw pair will produce a gap，Vibration and noise 3、The balls inside the original nuts are all the same size，Its locked with an oil seal，Relatively low noise，Replace the ball when worn out by use，In order to make a good preload and transport
Linear guide rail is often referred to as linear guide rail，Such mechanical parts are precision parts，therefore，At the time of use，A slight mistake，It will cause damage to the parts，therefore，During production operations，We must adopt a more cautious attitude towards production，Avoid damage to linear guide rails due to incorrect use。next，We will understand the matters to pay attention to when using linear guide rails。 1.Rust should be avoided Such use should be avoided，First of all, avoid directly using both hands to pick up such accessories，And the right thing to do
Linear guides are low-speed guides，High precision guide，Achieve high load and high precision linear motion。therefore，The precision adjustment of linear guide rail is very important。today，The small side will introduce the whole process of precision debugging of linear guide。Detailed steps of the linear guide precision adjustment process1.Linear guide rails have been widely used in various machine tools and non-standard equipment。We use wire drawing method to rough adjust the rail and place the slide on the rail，Mount a scale reading microscope on the slider，The diameter of the microscope lens is0.3mmVertical steel wire。2.The wire should be fixed at one end of the track，The other end should lift the weight by pulley，Then adjust the wire
With the wide use of high-precision linear guides in industrial automation，It is necessary to master certain installation skills，The correct installation method can improve the service life and accuracy of the guide rail。 To ensure the parallelism between the driven side slide and the reference side slide in the installation of the assembly surface without lateral positioning。 one、Install using the installation datum First, use the assembly screw to fix the base plane of the linear guide roughly to the assembly surface at the bottom of the bed，Then use the vice to push the reference surface of the slide rail side to tighten the assembly surface of the bed side，To determine the position of the slide，Use a torque wrench，Some torque
