Abstract
The utility model relates to a kind of high accuracy small diameter point lapping device, and the vertical plane of workbench is provided with rotating disc, and the main shaft of rotating disc is connected with the transmission device in workbench; Connect several cylinders on the rotating pan, the external end head of cylinder is provided with end cover, and the axis of the axis of cylinder and rotating disc at 45 ° ~ 60 °.This device effectively can carry out barreling to the tip of part by processing step, ensure that radius of curvature dimensions and the roughness at pivot tip, improves production efficiency and part qualification rate.
Description
Technical field
The invention relates to a kind of high accuracy small diameter point lapping device, and being applicable to the radius of curvature part metal grinding processing of high accuracy small diameter point, is a kind of grinding technique.
Background technology
The processing of high accuracy minor diameter part is much in current industrial production, particularly often meet in tabulation industry, precision equipment and instrument and meter, but the difficulties of attrition process really in an industrial processes is carried out to the radius of curvature part of some high accuracy small diameter point.
My company's product has a pivot part as shown in Figure 1, the less but precision of its size and surface roughness requirements higher, the particularly radius of curvature SR0.12 ± 0005mm at pivot tip, size and surface roughness 0.025 are difficult to ensure.
Summary of the invention
The technical problem that the invention will solve is to provide a kind of high accuracy small diameter point lapping device and Ginding process thereof, this device effectively can carry out barreling to the tip of part by processing step, ensure that radius of curvature dimensions and the roughness at pivot tip, improve production efficiency and part qualification rate.
For overcoming the above problems, the concrete technical scheme of the invention is as follows: a kind of high accuracy small diameter point lapping device, and the vertical plane of workbench is provided with rotating disc, and the main shaft of rotating disc is connected with the transmission device in workbench; Connect several cylinders on the rotating pan, the external end head of cylinder is provided with end cover, and the axis of the axis of cylinder and rotating disc at 45 ° ~ 60 °.
A kind of lapping device that adopts carries out high accuracy minor diameter pivot Ginding process, comprises the following steps:
1) first utilize the equipment such as lathe, grinding machine, polishing machine by part machine-shaping before tumbling grinding, and stay tumbling surplus;
2) in cylinder, first put into the shot of alumina powder 15 ~ 20 grams, No. 10 machine oil, diameter phi 1 ~ φ 1.5mm, and first add shot to 1/3 of cylinder volume, add machine oil to 3/4 of cylinder volume;
3) cover end cover, shake cylinder, make abrasive material, machine oil, mixing, then putting into the pivot part of machine-shaping again, the quantity of each pivot part is no more than 1500;
4), after tumbling grinding, shot, abrasive material mixed liquor and part are poured in pallet, then draws out part with bar magnet, carry out cleaning, demagnetizing.
Described tumbling grinding is divided into corase grind and fine grinding, and corase grind adopts the cylinder of φ 44mm × 100mm size, and drum rotating time is 20-24 hour; Fine grinding adopts the cylinder of φ 38 mm × 94 mm size, and drum rotating time is 36 hours.
This high accuracy small diameter point lapping device, by simple drum-inclined angle rotational structure, can solve the technical barrier of the radius of curvature of high accuracy small diameter point.
Meanwhile, adopt abrasive material, machine oil and shot as auxiliary material in process, thus ensure that the quality that tumbling is ground, thus heighten the qualification rate of product.
Preferably, adopt the cylinder of two kinds of different-diameters to carry out roughly grinding and fine grinding, thus ensure that the dimensional accuracy of tumbling.

Detailed description of the invention
As shown in Figures 2 and 3, a kind of high accuracy small diameter point lapping device, the vertical plane of workbench 1 is provided with rotating disc 2, and the main shaft 3 of rotating disc 2 is connected with the transmission device in workbench 1; Rotating disc 2 connects several cylinders 4, and the quantity of its intermediate roll has the quantity of pivot and determines, and pivot quantity is said, namely can be placed in different cylinders 4 respectively; The external end head of cylinder 4 is provided with end cover 5, and the axis of the axis of cylinder 4 and rotating disc 2 at 45 ° ~ 60 °.
A kind of lapping device that adopts carries out high accuracy minor diameter pivot Ginding process, comprises the following steps:
1) first utilize the equipment such as lathe, grinding machine, polishing machine by part machine-shaping before tumbling grinding, and stay tumbling surplus;
2) in cylinder, first put into the shot of alumina powder 15 ~ 20 grams, No. 10 machine oil, diameter phi 1 ~ φ 1.5mm, and first add shot to 1/3 of cylinder volume, add machine oil to 3/4 of cylinder volume;
3) cover end cover, shake cylinder, make abrasive material, machine oil, mixing, then putting into the pivot part of machine-shaping again, the quantity of each pivot part is no more than 1500;
4), after tumbling grinding, shot, abrasive material mixed liquor and part are poured in pallet, then draws out part with bar magnet, carry out cleaning, demagnetizing.
Described tumbling grinding is divided into corase grind and fine grinding, and corase grind adopts the cylinder of φ 44mm × 100mm size, and drum rotating time is 20-24 hour; Fine grinding adopts the cylinder of φ 38 mm × 94 mm size, and drum rotating time is 36 hours.
