Abstract
The utility model discloses a rotating table rotating shaft floating locking device and relates to the technical field of machine tool manufacturing. The rotating table rotating shaft floating locking device comprises a rotating table arranged on a track and a supporting sliding base. The track is arranged on the supporting sliding base through a plurality of locking machines which are arranged at intervals. The locking machines are provided with locking pressing plates. Grooves for clamping the track are formed in one sides of the locking pressing plates. The locking pressing plates are provided with oil cylinders on the two sides of the grooves respectively, and locking pistons are arranged in the oil cylinders. The oil cylinders are communicated with oil pipes connected with oil pumps through oil ways arranged in the locking pressing plates. Compared with the prior art, the problem that currently, when a locking sliding block with a wedge shape used is used for locking a rotating table, the using accuracy of the rotating table is lowered can be solved.
Description
Technical field
The utility model relates to technology of Machine Tool field, especially a kind of unsteady locking device of the NC rotary table gyroaxis for boring machine.
Background technology
The NC rotary table gyroaxis that boring machine uses does not participate in interlock and uses, gyroaxis just quits work after being turned back to assigned address, when boring machine adds man-hour because of the flywheel moment around B axle of feeding generation of boring axle, the rotating shaft of the Y-axis of line parallel in rectangular coordinate system centered by B axle; Therefore boring axle must be locked rotary table adding man-hour, and the size of coupling mechanism force and reliability directly have influence on the machining accuracy of workpiece.What at present rotary table is locked to generally employing is, between the track of rotary table and the support slide of this track, a plurality of locking sliding blocks that are connected with the wedge shape of hydraulic cylinder are set, Driven by Hydraulic Cylinder locking sliding block sliding shoe reaches track stretching the object of locking workbench, what locking relied on is the frictional force between locking sliding block and track, although can effectively lock rotary table, but in use there are the following problems: 1, the general guide rail adopting of rotary table is static-pressure guide rail structure, during work, rotary table floats, position due to hydraulic jack during locking is fixed, be provided with the oil film thickness of hydrostatic guide way attenuation at locking sliding block place, and then the service precision of reduction rotary table, while 2, using to a certain degree, locking sliding block has wearing and tearing, when the wear extent of each locking sliding block is inconsistent, causes the service precision of rotary table to reduce.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of rotary table gyroaxis that can carry out floating clamping mechanism according to rotary table floatation volume locking device that floats, and to solve the locking sliding block of existing use wedge shape, rotary table lock to the problem of the service precision reduction of the rotary table existing.
In order to address the above problem, the technical solution adopted in the utility model is: the unsteady locking device of this rotary table gyroaxis includes the rotary table of establishing in orbit and supports slide, described track is contained on described support slide by a plurality of spaced lockers, described locker has locking pressure plate, in described locking pressure plate one side, be provided with the groove that clamps described track, described locking pressure plate is equipped with the oil cylinder of latching ram in the both sides of described groove are respectively equipped with, described oil cylinder is communicated with the oil pipe that is connected with oil pump by the oil circuit being located in described locking pressure plate.
Above-mentioned rotary table gyroaxis floats in locking device technical scheme, and technical scheme can also be more specifically: between described latching ram and described oil cylinder inner wall, be provided with rubber seal.
Further, the described oil cylinder of the both sides of described groove is symmetrical set and oil circuit is between the two connected.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect: 1, when starting the unsteady locking device of rotary table gyroaxis, hydraulic oil enters respectively from oil circuit and in the oil cylinder that is located at groove both sides, promotes in-oil cylinder latching ram and move, when two latching rams touch respectively the upper and lower end face of track, can produce relative clamping force track is clamped, the locking of realization to track, because the oil cylinder in groove both sides is to be symmetrical arranged, coupling mechanism force can not setovered; In addition, two latching rams carry out fuel feeding by the oil circuit communicating together, when to track locking, can float and lock voluntarily according to the position of rotary table, can not cause the variation of floating amount of static guide track, also can not affect the service precision of rotary table 8; 2, clamp reliable and stablely, clamped position can fluctuate, and is not subject to oil film thickness variable effect, also can not exert an influence to static pressure oil film.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the partial enlarged drawing at the A place of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:
The unsteady locking device of rotary table gyroaxis as depicted in figs. 1 and 2 includes the rotary table 8 being arranged on track 1 and supports slide 7, and the locker that the present embodiment is divided equally setting at track 1 by eight intervals is contained in and supports on slide 7; Locker has locking pressure plate 3, in locking pressure plate 3 one sides, has the groove that clamps track 1, and the upper and lower both sides that are positioned at the groove of locking pressure plate 3 have oil cylinder, and upper and lower two oil cylinders are to be symmetrical arranged and oil circuit is between the two connected; In the oil cylinder of the upside of groove, the tight piston 2 of locking is housed, in the oil cylinder of the downside of groove, lower latching ram 6 is housed, between these two latching rams and oil cylinder inner wall separately, be provided with rubber seal, the rubber seal of the present embodiment is O RunddichtringO 10, and O RunddichtringO 10 is installed on respectively in the seal groove of two latching ram outer rims; Upper and lower two oil cylinders are all communicated with the oil pipe 5 that is connected with oil pump 9 by the oil circuit being located in locking pressure plate 3, and the pipe joint 4 being communicated with oil pipe 5 is housed in the oil circuit exit of locking pressure plate 3.
During work, hydraulic oil in oil circuit enters respectively the oil cylinder that is located at groove both sides, promote in-oil cylinder latching ram 2 and lower latching ram 6 move, when touching respectively the upper and lower end face of track 1, upper latching ram 2 and lower latching ram 6 produce relative clamping force by track 1 locking of clamping realization to track 1, because the oil cylinder in groove both sides is to be symmetrical arranged, coupling mechanism force can not setovered; In addition, two latching rams carry out fuel feeding by the oil circuit communicating together, when to track 1 locking, can float and lock voluntarily according to the position of rotary table 8, can not cause the variation of floating amount of static guide track, also can not affect the service precision of rotary table 8.
