Description

Small pneumatic auxiliary lifting grinding machine tool

Technical Field

The utility model belongs to the technical field of abrasive machining, especially, supplementary lift grinding lathe of small-size pneumatic type.

Background

Grinding, like other mechanical manufacturing techniques, is a vigorous and continuously developing technical field, which is a technical support for the development of modern technology on the one hand and continuously develops itself to a higher level under the influence of high technology on the other hand. In the 30's of the eighteenth century, grinders using natural abrasive grinding wheels were developed in uk, germany and usa, respectively, in order to adapt to the hardened machining of parts such as clocks, bicycles, sewing machines and firearms. The grinding machines are modified by additionally arranging grinding heads on the existing machine tools such as lathes, planing machines and the like, have simple structure and low rigidity, are easy to vibrate during grinding, and require high skills of operators to grind precise workpieces. The universal cylindrical grinder manufactured by brown-sharp corporation of america, shown at the paris exposition in 1876, is a machine that for the first time has the basic features of modern grinders. The workpiece headstock and tailstock are mounted on a reciprocating worktable, and the box-shaped lathe body improves the rigidity of the machine tool and is provided with an internal grinding accessory.

In 1883, the company produced a flat grinder with a grinding head mounted on a column and a table moving back and forth. Before and after 1900 years, the development of artificial abrasives and the application of hydraulic transmission have great promotion effect on the development of grinding machines. With the development of modern industry, in particular the automotive industry, various types of grinding machines have come out in succession. For example, in the beginning of the 20 th century, a planetary internal grinding machine, a crankshaft grinding machine, a camshaft grinding machine, a piston ring grinding machine with an electromagnetic chuck, and the like for machining a cylinder block were developed in sequence. The automatic measuring device started to be applied to the grinder in 1908. Before 1920 years ago, a centerless grinder, a parallel surface grinder, a roller grinder, a guide rail grinder, a honing machine, a superfinishing machine tool and the like are successively manufactured and used; in the 50 s, a high-precision external circular grinding machine capable of performing mirror surface grinding appeared; in the end of the 60 s, a high-speed grinding machine with a grinding wheel linear speed of 60-80 m/s and a large-depth-cutting slow-feeding grinding surface grinding machine appear; in the 70 s, technologies such as digital control and adaptive control by a microprocessor were widely applied to grinding machines.

The grinder can process materials with higher hardness, such as hardened steel, hard alloy and the like; brittle materials such as glass, granite, etc. can also be processed. The grinding machine can grind with high precision and small surface roughness, and can grind with high efficiency, such as strong grinding. A grinding machine is a machine tool that grinds the surface of a workpiece using a grinding tool. Most grinding machines perform grinding using a grinding wheel rotating at a high speed, and a few grinding machines perform grinding using oilstones, sanding belts and other grinders and free abrasives, such as honing machines, superfinishing machines, sanding belt grinders, grinding machines, polishing machines, and the like. At present, grinding machines are mainly divided into the following types:

1. cylindrical grinding machine: is a common basic type series and is mainly used for grinding machines for grinding cylindrical and conical outer surfaces.

2. An internal grinding machine: is a common type of basic model series, mainly used for grinding machines for grinding cylindrical and conical internal 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 precise coordinate positioning device.

4. Centerless grinding machine: workpieces are clamped centreless and are generally supported between a guide wheel and a bracket, and the guide wheel drives the workpieces to rotate, mainly for 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.

6. Abrasive belt grinding machine: a grinding machine for grinding with a fast moving belt.

7. Honing machine: grinding machines for honing various surfaces of a workpiece.

8. Grinding machine: the grinding machine is used for grinding the plane or cylindrical inner and outer surfaces 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 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 machines, crankshaft grinding machines, cam grinding machines, gear grinding machines, thread grinding machines, profile grinding machines and the like.

13. End surface grinding machine: a grinding machine for grinding the end face of a gear.

The current traditional hand-held grinding mode not only has great risk, and grinding efficiency is low moreover, the precision is poor, and the limitation is great.
