Working principle of the buffer and the installation process

Abstract: Buffer is one kind of digital components. It can make the work of the high-speed CPU and peripheral slow work coordination and buffer role, realizes the data transmission synchronization.

 

  Buffer is one kind of digital components, it does not perform any operations on the input value, the output value and input values, but it plays an important role in the design of the computer.
  Buffer is divided into two kinds, the conventional buffer (often said buffer) and tri-state buffers. The conventional buffer will always value directly output, use in advancing the current to the high level of the circuit system. Tri-state buffers in addition to the function of the conventional buffer, there are a cartoon input options, expressed in E. When E = 0 and E = 1 has different output values.
  When the E = 1, time, its input directly to the output;
  If E = 0, buffer be stopped, no matter what input values, the output is high impedance state, represented by Z. High resistance state can cause the current to a low enough, so that as the output of the buffer is not connected to anything.
  Buffer includes shell and installed in the casing of the resilient rubber energy-absorbing component, one end of the shell equipped with a clamp, the clamp beforehand and resilient rubber energy absorption components with shell part of the elastic contact, the outer edge and a connection board in the process of the pressure plate is even, highlight the outside edge of the shell in advance between the clamp and the connecting plate, the buffer between connected to highlight the outer edge of plate and shell with embedded block. Precompression structure buffer compress energy absorption components make buffer structure size smaller. When installation without further compression, which can be installed directly, simplifies the installation process, improved the working conditions of workers. Still sliding inside the installation seat adjusts the buffer settings have the pull rod. Tie rod end into the buffer, out the other end of the installation set connected to the regulating mechanism. Fixed way to furniture plate clamps connection method, achieve rapid installation. Its structure is the simple reason, adjustment precision large, easy installation and removal, applicable to a wide range.

  Drilling machine and dynamic head have the same of principle, refers to the use of more hard than the target, more sharp tools by means of rotary cutting or rotating extrusion, below is the drill operation steps and matters needing attention.
  Drilling machine operation steps:
1. First cutting coolant to more than 1 to 10 ratio after mixing properly, injecting cutting coolant storage tank.
2. Drill guide hole in the work content in advance, one half of the depth of the drill diameter.
3. Confirm the drill bit is firmly locked in the clamping sleeve, and firmly connected on the main shaft; at the same time good for cutting the centerline. Will cut coolant storage tank and nozzle of the merger is connected to the workhorses.
4. Drill blade tip extends into the guide sleeve or guide hole, but not make cutting-edge touch the guide sleeve or guiding hole at the bottom.
5. Open the sliding or double valve, adjust the atomized mixture to the appropriate state, select the appropriate speed and feed speed.
6. Activation of spindle and feed, and make sure the chip stability and continuity of production. If they are wrapped in the scrap metal, please immediately reduce the feeding speed.
  Drilling machine matters needing attention:
  In cutting process, continually check bit edge wear, when retract, you should stop the spindle rotation. Just need to add a gun drill system, for lower speed of machine tools, and some need to install an accelerator.

Which areas general application of Multi-axis drilling?

  Multi-axis drilling work is mainly based on the existence of multi-axis control can be realized. The main working principle is based on the multi-axis machine spindle rotation to drive the other axis of rotation of multi-axis machine.
  Multi-axis drilling machine is widely used in the porous parts of drilling and tapping processing machinery industry. Porous parts such as automobile, motorcycle, engine body shell, aluminum castings, the wheel hub, brake drum, brake disc, steering gear, differential shell, shaft head, half shaft, axle, pump, valve, hydraulic components, solar accessories, and so on.
  Multi-axis drilling machine can be divided into fixed and adjustable two specifications. Adjustable multi-axis drilling machine within the scope of the processing, the distance between the numbers of the spindle, spindle, relative can be arbitrary adjustment, a feed processing several holes at the same time. In its hydraulic machine tool work, can be automatically fast forward, fast into retreat (time), back, and stop. Compared with single shaft drill (tapping), workpiece machining accuracy high, fast efficiency can effectively save investment of manpower, material and financial resources. Especially machine tool automation greatly reduces the labor intensity of operators. Stationary multi-axis drilling machine adopts single piece (the job) plane design scheme, based on its high frequency of mechanical parts processing, the reasons of the large amount, specifically tailored to a device in one, in the work you must be worried about the size run and nerve-racking. In addition to using conventional products, also according to customer specific requirements for special designs.
