Description
Technical Field
The invention relates to the field of peristaltic grinding machines, in particular to a novel peristaltic grinding machine.
Background
The classification of grinding machines includes the following:
1. ordinary cylindrical grinder: is a common type of basic model series and is mainly used for grinding machines for grinding cylindrical and conical outer surfaces.
2. Traditional internal grinding machine: is a common type of basic model series and is mainly used for grinding machines for grinding cylindrical and conical inner surfaces. In addition, a grinding machine with internal and external circular grinding is also provided.
3. A coordinate grinder: an internal grinding machine with a precision coordinate positioning device.
4. Centerless grinding machine: workpieces are held by a centerless clamp, typically supported between a guide wheel and a carriage, and are driven to rotate by the guide wheel, primarily for use in grinding machines for grinding cylindrical surfaces. Such as a bearing shaft support or the like.
5. A surface grinder: the grinding machine is mainly used for grinding the plane of a workpiece. a. The hand-operated grinding machine is suitable for machining workpieces with smaller size and higher precision and can machine various special-shaped workpieces including cambered surfaces, planes, grooves and the like. b. The large water mill is suitable for processing larger workpieces, has low processing precision and is different from a hand-operated grinding machine.
6. Abrasive belt grinding machine: a grinding machine for grinding with a fast moving belt.
7. Honing machine: grinding machines are used for honing various surfaces of workpieces.
8. Grinding machine: the grinding machine is used for grinding the inner surface and the outer surface of a plane or a cylinder of a workpiece.
9. A guide rail grinding machine: the grinding machine is mainly used for grinding the guide rail surface of the machine tool.
10. Tool grinding machine: a grinding machine for use in grinding a tool.
11. A multipurpose grinding machine: a grinding machine for grinding cylindrical, conical inner and outer surfaces or flat surfaces and capable of grinding a variety of workpieces with followers and attachments.
12. A special grinding machine: special machine tool for grinding some parts. According to the processing objects, the method can be divided into: spline shaft grinding machine, crankshaft grinding machine, cam grinding machine, gear grinding machine, thread grinding machine, profile grinding machine.
13. Creep feed grinding, a creep grinding machine, is a grinding process, but more importantly, it is not like other forms of grinding. The creep feed grinding is processed by adopting a deep cutting and large metal cutting amount mode, and is characterized in that: a lower feed rate is used instead of a fast reciprocating motion. The creep grinding tool, i.e. the grinding wheel, is buried deeply in the processed material for processing like a milling cutter head.
Why is creep feed grinding used?
Since other such processes present certain problems. Creep processing has some of the following advantages:
(1) has excellent processing characteristics. Such grinding can absorb a portion of the heat in the machining cut. It is more effective, particularly in the machining of titanium metal, inconel and other materials, mainly because the heat generated during machining accelerates the wear of milling or broaching tools;
(2) maintaining a good surface finish. The grinding process does not require the application of particularly high pressures to the work surface, but the ability to grind materials is high, while maintaining good surface finish and perfect surface finish quality;
(3) no burr is produced. The adoption of the grinding processing does not need to bur;
(4) the inherent accuracy can be maintained. Under the well designed technological conditions, the milling machining and the broaching machining can obtain high machining precision.
The peristaltic grinding machine in the prior art has the following defects:
1. the traditional peristaltic grinder adopts a servo motor matched with a screw rod to perform rotary motion;
2. the grinding wheel drive adopts a common four-phase motor, the main shaft structure is more complex, and slight vibration exists;
3. the traditional peristaltic grinding machine adopts a manual regulation and control rotating spindle seat for many times, and cannot adapt to workpieces with complex processing steps and more rotating times.
