Abstract

The utility model relates to a locating ring which is taken as a backer of a mechanical processing or measuring fixture, in particular to a locating ring that is installed on a special machine tool or the fixture and is used for processing or detecting bearing parts in batch. The locating ring comprises a ring body, one end surface of which is also fixed with a ball body, and the two end surfaces of the ring body are parallel smooth end surfaces. The ball body is made of ceramic material; the number and diameter of the ceramic ball body have direct proportion with the wall thickness and the diameter of a processed part; and the ceramic material has the characteristics of abrasion resistance, corrosion resistance, high temperature resistance, electric insulation, no magnetic conduction, high strength and hardness within HRC 75-80, high rigidity, small specific gravity and the like, so that the locating ring made of the ceramic material can normally run under the conditions of high rotating speed and low lubrication, and can reduce friction, vibration and noise, thus achieving the aims of improving the working efficiency, prolonging the service life and reducing the production cost. The locating ring does not need to be frequently replaced, thus not only lightening the labor intensity and greatly improving the work reliability.

Description

Locating ring

Technical field

The utility model relates to a kind of machining or measures the backer who uses jig, and particularly a kind of being installed on special purpose machine tool or the jig is used for bearing parts processing or bearing parts are detected the locating ring that uses.

Background technology

Production of bearing enterprise cuts down finished cost for boosting productivity, and guarantees constant product quality, reduce labor intensity, in particular for the processing in enormous quantities to standardized element, general enterprise all adopts the special machine bed, and the machine adopted electric magnetic no-core clamp, locate with locating ring.As the batch process of the inside and outside lasso of bearing parts, generally speaking as long as change backer on special purpose machine tool or the jig, i.e. the bearing parts of different size just can directly be produced or detect to the locating ring of identical, the different sizes of shape in batches.

As adopt full-automatic raceway groove to process grinding machine 3MZ143, special purpose machine tool machining bearing outer rings such as 3MZ146, use 3MZ133, special purpose machine tool machining bearing inner rings such as 3MZ131, it is the bearing steel material making of HRC61～65 that general locating ring all adopts through heat treatment hardness, lathe, jig is in working order the time, because of processing work will and backer's locating ring between produce relative motion, lasting friction takes place, will sharply wear and tear in normal phase work locating ring surface, because wearing and tearing are inhomogeneous, the location end face of locating ring is with regard to out-of-flatness, thereby have influence on the crudy of processing work, at this moment the locating surface of reconditioning locating ring or the locating ring that more renews again again, also need readjust the center of lathe and jig after the transposing, it is time-consuming again to have increased a lot of workloads, effort has also increased production cost.

The patent No. 200820127370.1 " grinding locating ring " also provides a kind of locating ring, and the locating ring of the duplex connecting structure that is made of the stainless steel material and the high molecule plastic material of rigidity.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of locating ring is provided, and it is simple in structure, and wearability is good, can carry out batch machining production with special purpose machine tool is supporting, and durable in use, increase the service life, reduce labor intensity, raise labour productivity.

The technical scheme in the invention for solving the above technical problem is: locating ring, comprise ring body, and also be fixed with spheroid on the end face of described ring body, and the both ends of the surface of ring body are parallel smooth both ends of the surface.

Described spheroid is become by ceramic material, and the quantity of spheroid and diameter d are directly proportional the center distance S=d+1.5 between each spheroid～5mm with the wall thickness and the diameter of workpiece to be machined.

Described ring body is made by bearing steel material, and aperture uniform, at interval is arranged on the ring body, and little hole depth is h, and h=2/3d, the width of ring body are b, b=d+0.6～2mm, and the radius R of ring body and the size of workpiece to be machined are complementary.

Compared with prior art, advantage of the present utility model is: because of embed the spheroid that is fixed with by ceramic material on locating ring, and that ceramic material possesses is wear-resisting, anti-corrosion, high temperature resistant and electric insulation, magnetic conduction not, high strength hardness is in HRC75～80, and high rigidity, performance characteristics such as proportion is little, thereby by its locating ring that is made into, can be at high rotating speed, normally operation under the low lubricated occasion, and can reduce friction and vibrate, reduce the noise easy care, the purpose that thereby reaching increases work efficiency increases the service life, and reduce production costs, do not need the often new locating ring of transposing, reduce labor intensity, significantly improve the reliability of work, the batch process of suitable especially bearing parts is used.

Fig. 2 is the ring body structurc schematic diagram;

Fig. 3 is a user mode reference diagram of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Ring body 1 is made by bearing steel material, the radius R of ring body 1 is decided by the size of workpiece to be machined 5 and is complementary, the width of ring body is b, interval, uniform ground auger aperture 3 on an end face of ring body 1, aperture 3 is h deeply, h=2/3d, b=d+0.6～2mm are that locating ring ring body 1 width b is than the big 0.6～2mm of spheroid 2 diameter d.

Spheroid 2 is by ceramic material silicon nitride Si ₃N ₄Be made into, diameter is d.The wall thickness of workpiece to be machined is big more, and its bulb diameter is also big more, and the workpiece to be machined diameter is big more, and spheroid quantity is many more.

Center distance S=d+1.5～5mm that each spheroid is 2.

Each spheroid 2 is embedded in the aperture 3 on ring body 1, and spheroid 2 is bonded and fixed in the aperture 3 on ring body 1 surface with binding agent.

The both ends of the surface that will have the ring body 1 of spheroid 2 then polish, and soon spheroid 2 exposes partly and polishes, and makes its smooth surface make locating ring.

During use, locating ring is installed in does the backer on machine tool chief axis 4 or the anchor clamps and use, will have an end face of spheroid 2 to be close to workpiece to be machined 5, as the outer ring of machining bearing, as shown in Figure 3.

Machining shape is identical, the bearing parts of different size if want, as long as change the locating ring as lathe, anchor clamps backer, just can directly produce the bearing parts of different size in batches, and change easy to use.
