Brackets for rails

Any device used to secure rails on chairs or base plates or directly to sleepers, brackets or other rail supports. The rail fastening keeps the rails fastened to the sleepers (transfer of forces), provides adequate slope of the rail foot (1:20, 1:40) in the transverse plane, prevents the rail from moving longitudinally, dampens the noise And vibrations from the rails.
General requirements for rail fasteners
Rail fasteners shall:
1. Hold the rails firmly on the rail seat.

design and fabrication of pneumatic auto feed drilling machiner eport

abstract

in small-scale industries and automobile maintenance shops, there are frequent needs of
tightening and loosening of screws, drilling, boring, grinding machine. huge and complicated
designed parts cannot be machined with the help of an ordinary machine and further for every
operation separate machine is required therefore increasing the number of machines required and
increasing the area required for them to be accommodated and hence overall initial cost req ....etc

Types and Functions of Jigs and Fixtures
JIGS AND FIXTURES
Jigs and fixtures are production-workholding devices
used to manufacture duplicate parts accurately. The
correct relationship and alignment between the cutter,
or other tool, and the workpiece must be maintained.
To do this, a jig or fixture is designed and built to hold,
support, and locate every part to ensure that each is
drilled or machined within the specified limits.
Jigs and fixtures are so closely related that the
terms are sometimes confuse ....etc

Elements of Jigs and Fixtures



1: Body:
The jig body is generally made of cost iron by casting process or fabricated by welding together various slabs and bars of mild steel. It may be heat treated to relief the stresses. Body is the most prominent feature of the jig. Its main purpose is to support and house the job.

The various jig body are follows:

(A):Plane Type Jig:
Plane type jig is the simplest type, it is used when plane holes are to be drilled. It has either d ....etc
