Abstract
The invention relates to a turntable bearing for an industrial robot, and belongs to the field of mechanisms. According to the structure design, the turntable bearing for the industrial robot is characterized in that an adjusting isolating block is added and can minimize the total gap in the circumference direction, so that the problem of controlling the diameter of a rolling body, the accuracy of an isolating block and the diameter of a ball track of a traditional turntable bearing can be avoided, and as a result, the cost can be greatly saved.
Description
Technical field
The present invention relates to the turntable bearing for industrial robot, it belongs to mechanical field.
Background technique
Industrial robot, as the support technology of advanced manufacturing industry and the new industry of information-based society, by to produce future and social development plays a part more and more important.Industry of industrial robots has been listed in 13 planning by China, and developing industry robot has great strategic importance, and it is measurement country
manufacturethe important symbol of industry level and scientific and technological level is also important tool and the means of reinventing China's manufacturing industry competitive advantage, accelerates the pragmatic choosing of China's industrial repositioning upgrading especially.
But the critical component of China's industrial robot still depends on import at present, especially uses turntable bearing bottom robot.The bearing at this position is very high to precision prescribed of beating, and needs reciprocating rotary, and sometimes according to working condition requirement, vertical installation wanted by bearing.For common turntable bearing, after assembling, circumference total backlash is difficult to ensure, this total backlash can be very large usually.If the vertical installation of bearing, gap major part can be accumulated at top, and not only bad for the smooth operation of rolling element and spacing block, time serious, spacing block can conjugate, and causes the damage that bearing is too early.
Therefore, research and develop high-accuracy industrial robot turntable bearing, to promoting that the long term growth of Robot industry is significant.
Summary of the invention
In view of the defect that existing production method exists, the invention provides the turntable bearing for industrial robot, in structural design, increase adjustment spacing block, adjustment spacing block farthest can reduce the total backlash of circumferencial direction, avoid turntable bearing Traditional control rolling element diameter, spacing block precision, raceway diameter, greatly save cost.
For achieving the above object, the technical solution adopted in the present invention is that described in turntable bearing for industrial robot, turntable bearing comprises the first seat ring, bolt, the second seat ring, blowout patche, seal ring, nut, roller and split spacing block; Between seat ring and blowout patche, seal ring is set, first seat ring and the second seat ring are fixed by bolts and nuts, raceway is provided with between seat ring and blowout patche, several split spacing blocks and several rollers are set in raceway, between every two rollers, a split spacing block is set, the intermediate beam variable-width be positioned on two roller centre point line directions of split spacing block.
Described roller is cylindrical body, and the center line of adjacent two cylindrical body rollers is 90 degree, cylindrical body roller successively cross arrangement on raceway.
Described split spacing block is two classes, and a class is conventional spacing block, and another kind of is the adjustment spacing block that intermediate beam is larger than conventional spacing block size.
The dimensional range of described adjustment spacing block is 1 ± 0.2mm larger than the intermediate beam of the spacing block of routine.
The dimensional range of described adjustment spacing block chooses the value according to split spacing block circumferencial direction total backlash.
First by conventional spacing block normal mounting in raceway, by the value of apparatus measures circumferencial direction total backlash, according to operating mode, then replace conventional spacing block with adjustment spacing block, until circumferencial direction total backlash working condition requirement.
Described rolling element is spherical.
After adopting said method, there is compared with art methods following beneficial effect:
Turntable bearing precision of the present invention is high, speed is high, is applied to the mechanical significant points such as high-accuracy industrial robot rotating platform, high-precision machine tool turntable and high-speed tire forming machine rocking arm, uses through installation, respond well.
Accompanying drawing explanation
Fig. 1 is the turntable bearing Local map of band adjustment spacing block;
Fig. 2 is conventional spacing block;
Fig. 3 is adjustment spacing block.
Wherein: 1, the first seat ring, 2, bolt, 3 split spacing blocks, 4, roller, 5, blowout patche, 6 second seat rings, 7, seal ring, 8, nut, 9, conventional spacing block, 10, adjustment spacing block.
Specific embodiment
Existing cylinder rolling element is 100, then split spacing block is also 100.Split spacing block divides a, b two kinds, and a is the conventional spacing block that intermediate beam is less, and b is the adjustment spacing block that intermediate beam is larger.When design modifying spacing block, b type intermediate beam is about 1mm larger than a type intermediate beam generally, this value mainly still depends on the operating mode, precision etc. of product, about 1mm is that validity is high, the numerical value that universality is best, when needing less circumferencial direction total backlash, b is more smaller than the increment of a intermediate beam, and increment hour precision is larger.φ Dw is roller diameter.
Set-up procedure:
First use 100 rolling elements and 100 a type spacing block normal mounting in raceway.By the value of apparatus measures circumferencial direction total backlash, the requirement of contrast drawing.A type spacing block is replaced, until circumferencial direction total backlash meets drawing requirement again with b type adjustment spacing block.Specifically choose the method for b type adjustment spacing block, if be 0.6mm with the value of apparatus measures circumferencial direction total backlash, when working condition requirement is higher, can the adjustment spacing block of design and installation 0.5mm specification.
