Abstract
The utility model discloses a three-axis precision ball core grinder for a hard sealing ball valve. The three-axis precision ball core grinder comprises a motor and a grinding disk assembly, wherein the grinding disk assembly is linked with the motor; a first belt wheel is arranged on an output shaft of the motor and is connected with a second belt wheel which is arranged on a transmission shaft; the transmission shaft is connected with the grinding disk assembly; a hole adaptive to the surface of a ball core of a ball valve is formed in the middle of the grinding disk assembly; the ball core of the ball valve is fixed on a base through a clamp; a planet is arranged between the transmission shaft and the grinding disk assembly, is fixed at one end of the transmission shaft through a bracket and is fixedly connected with the grinding disk assembly through a planet shaft. Different from conventional two-axis semi-grinding equipment, the three-axis precision ball core grinder for the hard sealing ball valve has the advantages that by adding the planet shaft, grinding transmission is steadier, the grinding disk assembly is tightly attached to a workpiece such as the ball core, the processing accuracy is improved, the defective rate is reduced, and the processing efficiency is improved.
Description
Technical field
The utility model belongs to field of machining, is specifically related to a kind of hard seal ball valve three-axis accurate ball core grinder.
Background technology
Ball valve was come out the 1950's, along with scientific and technical develop rapidly, production technology and product structure update, it has developed rapidly becomes a kind of main valve class.Ball valve is widely used in industries such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, iron and steel, occupies very important status in national economy.
Ball valve comprises the parts such as ball core, valve seat, and wherein ball core is key components and parts.At present, it is substantially all that milling apparatus with two axles half is being processed that known ball core grinds, and this two axle half abrasive machining apparatus exist poor product quality, defect that working (machining) efficiency is low.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of hard seal ball valve three-axis accurate ball core grinder that improves working (machining) efficiency and machining accuracy.
For solving the problems of the technologies described above, a kind of hard seal ball valve three-axis accurate ball core grinder of the present utility model, comprise motor and with the mill assembly of described motor linkage, the output shaft of described motor is equipped with the first belt pulley, described the first belt pulley is connected with the second belt pulley being arranged on power transmission shaft, described power transmission shaft is connected with mill assembly, the centre of described mill assembly has the hole that the surface with ball valve ball core adapts, described ball valve ball core is fixed on base by fixture, between described power transmission shaft and mill assembly, be provided with planet, described planet is fixed on one end of power transmission shaft by support, described planet is fixedly connected with mill assembly by planet axis.
For further improving grinding precision and working (machining) efficiency, above-mentioned planet is two, is fixedly connected with respectively by two planet axis with mill assembly.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is different from two traditional axle half abrasive machining apparatus, owing to having increased planet axis, makes to grind transmission more steady, between the workpiece such as mill assembly and ball core, fit tightly, not only improve machining accuracy, reduced defect rate, and improved working (machining) efficiency.The utility model is reasonable in design, and repacking cost is low, is easy to promote.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of hard seal ball valve three-axis accurate of the utility model ball core grinder.
The specific embodiment
As shown in Figure 1, a kind of hard seal ball valve three-axis accurate ball core grinder, comprise motor 1 and the mill assembly 7 linking with described motor 1, the output shaft of described motor 1 is equipped with the first belt pulley 2, described the first belt pulley 2 is connected with the second belt pulley 3 being arranged on power transmission shaft, described power transmission shaft is connected with mill assembly 7, the centre of described mill assembly 7 has the hole that the surface with ball valve ball core 8 adapts, described ball valve ball core 8 is fixed on base 9 by fixture, between described power transmission shaft and mill assembly 7, be provided with planet 5, described planet 5 is fixed on one end of power transmission shaft by support 4, described planet 5 is fixedly connected with mill assembly 7 by planet axis 6.
When ball core workpiece is ground, ball valve ball core 8 is fixed on base 9 by fixture, ball valve ball core 8 rotates with the rotation of fixture, mill assembly 7 fits tightly with the surface of ball valve ball core 8, open motor 1, the first belt pulley 2 drives the second belt pulley 3, power transmission shaft rotates and drives planet 5, planet axis 6 is rotated, thereby make 7 pairs of ball valve ball cores of mill assembly 8 carry out attrition process, in process, owing to passing through planet axis 6 band movable grinding disc assemblies 7, rotate, mill assembly 7 can automatically be revised in process of lapping, improved working (machining) efficiency, be specially adapted to the ultraprecision grinding to workpiece such as ball cores.
For further improving machining accuracy and working (machining) efficiency, two planets can be set, two planets rotate by planet axis band movable grinding disc assembly respectively, the simultaneous grinding of realization to a plurality of, ball core, now, the laminating of mill and ball wicking surface is tightr, has further improved working (machining) efficiency and precision.
