A high-precision honing device

Abstract

A high-precision honing device belongs to the technical field of machining tools, and in particular relates to a multifunctional high-precision honing device. The invention provides a high-precision honing device with simple structure, low production cost, capable of honing various heterosexual surfaces, and multiple functions. The invention includes a base, which is characterized in that: the base is provided with an overturning frame through a rotating shaft, and a return spring is provided between the end of the overturning frame and the base through a guide rod; shaft, a working head is movably arranged on the connecting head at one end of the honing shaft.

Problems solved by technology

[0002] The flange surface of the rotary body parts, especially the flange surface on both sides of the groove, after the roughness is lower than Ra0.8, the ordinary cylindrical grinder can only reach Ra1.6 or Ra0.8. For high-precision surface zero Parts processing, there has been a lack of effective processing methods

[0003] The patent number is 200810167896.7, the name is the invention patent of "Multifunctional Honing Head", which discloses a honing device, which realizes the honing of the surface of the workpiece by setting a honing wheel at both ends of a swing arm; The device is provided with at least two honing wheels, although the patent document states that the use of multiple honing wheels can improve work efficiency, but in practical applications, the effect of increasing the work efficiency by adding honing wheels is not obvious ; On the contrary, there are serious defects in using two or more honing wheels: when the workpiece to be processed is a special-shaped surface, such as the flange surface on both sides of the groove, multiple grinding wheels cannot enter, and the grinding work cannot be carried out; for Some shafts with smaller diameters cannot be ground

[0005] Third, this patent document also discloses that the swing arm of the honing head can be rotated 180°, and the honing state of the inner and outer circles can be changed through this rotation, but since the swing arm can rotate, when the honing head is honing, it will be subject to a large lateral force. This will lead to uneven force on two or more honing wheels, affecting the honing accuracy, and may also cause partial grinding and other phenomena

[0006] Fourth, due to its own structure, the patent also has certain restrictions on its functions, making it difficult to expand its functions
