Abstract
The utility model discloses an anti-backlash mechanism for a hydraulic motor gear of a cutting machine rotating table. A rack wheel is fixed on a spindle of the rotating table; a pinion is arranged on a hydraulic motor; the pinion is meshed with the rack wheel; and two oil tubes are communicated with the hydraulic motor. According to the utility model, damping which is opposite to the movement direction of the pinion is provided through the hydraulic motor, so as to achieve the anti-backlash purpose of the gear; the rotating precision of a work bench is improved, so as to improve the machining precision of the part; the two high-pressure oil tubes are arranged to respectively supply oil, and damping in two directions of the pinion can be provided, so that the clearance of a worm gear can be effectively removed after the work bench reversely rotates.
Description
Technical field
The utility model relates to a kind of stock-removing machine that needs the precision round subsection workbench that is applicable to and is used for eliminating the hydraulic motor gear clearance elimination mechanism in rotary table worm gear gap.
Background technology
Development along with the modern machine technology; One of developing direction of lathe is a high accuracy; Workbench is as one of core component of lathe, and its precision directly is decided by the element precision that processed, and traditional high-precision workbench mainly adopts the worm and gear transmission; Except requiring to use the high-precision worm gear, the gap of eliminating in the transmission process also is very crucial.Because all can there be certain sideshake in worm gear mechanism, if can not effectively eliminate in the course of work, not only directly influences transmission accuracy, also can reduce the rigidity of workbench in the process, finally influences the machining accuracy of part.So it is important to eliminate work table rotation gap ten minutes.
Summary of the invention
The purpose of the utility model provides a kind ofly can effectively eliminate the anti-backlash mechanism in work table rotation gap.
The purpose of the utility model is achieved in that a kind of hydraulic motor gear clearance elimination mechanism of stock-removing machine rotary table; Gear wheel is fixed on the main shaft of rotary table; Pinion is installed on the hydraulic motor, pinion and gear wheel engagement, and oil pipe communicates with hydraulic motor.Above-mentioned oil pipe is two.
The hydraulic motor gear clearance elimination mechanism of the stock-removing machine rotary table that the utility model provides; Through hydraulic motor the damping opposite with the pinion direction of motion is provided; Thereby reach the purpose of eliminating gear clearance elimination, improve the rotation precision of workbench, thereby improve the machining accuracy of part; Through two high-pressure oil pipes fuel feeding respectively is set, the damping of pinion both direction can be provided, after the workbench reverse rotation, also can effectively eliminate the gap of worm gear like this.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is the structural representation of the utility model.
The specific embodiment
As shown in Figure 1; A kind of hydraulic motor gear clearance elimination mechanism of stock-removing machine rotary table; Gear wheel 1 is fixed on the main shaft of rotary table, and pinion 2 is installed on the hydraulic motor 4, pinion 2 and gear wheel 1 engagement; Oil pipe 5 communicates with hydraulic motor 4, between pinion 2 and hydraulic motor 4, is provided with mounting bracket 3.Described oil pipe 5 is two.
Operation principle is following: when workbench rotated, the gear wheel 1 that is connected with rotary main shaft was in company with rotating, because gear wheel 1 and pinion 2 engagements, pinion 2 can passive rotation.Because pinion 2 links to each other with hydraulic motor 4; When high-pressure oil pipe 5 oil-feeds of hydraulic motor 4, the formula that becomes that the power that hydraulic oil provides has pinion 2 to stop gear wheel 1 to rotate, but because the insufficient pressure (pressure that high-pressure oil pipe provides is adjustable) that high-pressure oil pipe 5 provides; Pinion 2 can't stop gear wheel 1 to rotate; Just seamlessly be interlocked with gear wheel 1 tightly always, passive rotation, thus reach the purpose in the crack that disappears.When the workbench counter-rotation, these root oil pipe 5 fuel cut-offs then, another root oil pipe begins fuel feeding, for pinion 2 provides reciprocal damping, can reach the purpose in the crack that disappears in the same old way.The hydraulic oil that comes out from Hydraulic Station enters hydraulic motor 4 and flows to table base for it after power is provided, and gets back to Hydraulic Station through oil return pipe again, form a circulating system, so hydraulic oil reuses.
