Description
Technical field
The present invention relates to the motion on a kind of large automatic production equipment, particularly a kind of slipway mechanism.
Background technology
Along with the development of modernization of industry process, some large automatic production equipments obtain and apply more and more widely in industrial products process.Such as cold headers, metal working milling machine and machining center etc.
These above-mentioned big scale production equipments all can relate to one or multiple slipway mechanisms, each slipway mechanism again by guide rail sliding plate and along this guide rail sliding plate do straight reciprocating motion slide unit two parts composition, described slide unit face wherein and guide rail sliding plate bonded to each other.Therefore, can above-mentioned slide unit face and guide rail sliding plate fit tolerance between the two will decide this slide unit and carry out long-term and stable slidably reciprocating along guide rail sliding plate.But its guide rail sliding plate in existing slipway mechanism is once on the lathe bed of main equipment after fixed installation, its position relative to slide unit face all can not adjust on locus.Like this, above-mentioned slipway mechanism after a long time use, once occur that the surface of slide unit or guide rail sliding plate uses or the situation of non-normal use because of long-time, when occurring mechanical wear or physical deformation occur, will gap be produced between the close-fitting slide unit of this script and the binding face of guide rail sliding plate, thus cause slide unit to run precision decline.
Therefore, applicant thinks and is necessary that making further structure to the guide rail sliding plate in the slipway mechanism of said structure or slipway mechanism improves.
Summary of the invention
The object of the invention is to provide a kind of slipway mechanism to solve above-mentioned the deficiencies in the prior art.Guide rail sliding plate in this slipway mechanism is relative to the distance of machine tool body, and the angle angle of this guide rail sliding plate himself and space basal plane all can be carried out trace and regulated.
To achieve these goals, a kind of slipway mechanism designed by the present invention, comprise activity to be mounted to the guide rail sliding plate on machine tool body and to carry out the slide unit of straight reciprocating motion along this guide rail sliding plate, it is characterized in that above-mentioned guide rail sliding plate movable structure of installing on machine tool body is: described machine tool body is provided with more than one internal thread through hole, external screw thread axle sleeve is equipped with in each internal thread through hole, and both mutual threaded engagement, in each external screw thread axle sleeve, equal gap is socketed with axostylus axostyle, the two side ends of each axostylus axostyle all extends machine tool body, and a side end is wherein external thread section, external thread section is connected with locking nut, end side is then in ball head structure, above-mentioned more than one axostylus axostyle bulb joint activity ball connects same guide rail sliding plate, towards the end all spherically structure of guide rail sliding plate on above-mentioned each external screw thread axle sleeve, above-mentioned guide runner is provided with the spherical concave surface corresponding one by one with the sphere end of each external screw thread axle sleeve, and above-mentioned sphere end extends into its corresponding spherical concave surface, and fit with it.
A kind of slipway mechanism in above-mentioned, when the external screw thread axle sleeve in its structure in more than one internal thread through hole carries out synchronous adjustment, one piece of guide rail sliding plate that its joint activity ball connects just changes relative to the distance of machine tool body; Simultaneously, when in the external screw thread axle sleeve in above-mentioned more than one internal thread through hole single or multiple adjust separately time, consider the socket gap surplus of each external screw thread axle sleeve and axostylus axostyle and the mating spherical surfaces relation of each external screw thread axle sleeve and guide rail sliding plate, the angle angle of this guide rail sliding plate and space basal plane will produce trace and change.
During the slipway mechanism of said structure uses on the machine tool body of main equipment, when fitting tension or crossing loose situation appears in the mating surface of the described slide unit in its structure and guide rail sliding plate, user can multiple external screw thread axle sleeves on this machine tool body of adjusted in concert, thus adjustment guide rail sliding plate and slide unit fit clearance between the two, until this fit clearance is adjusted to reasonable zones values, then lock the locking nut on axostylus axostyle corresponding to each external screw thread axle sleeve one by one; When occurring concentrated wear because use for a long time or there is production and processing defect, cause guide rail sliding plate mating surface on slide unit described in its structure or/and slide unit mating surface out-of-flatness on guide rail sliding plate time, user to one of them in above-mentioned multiple external screw thread axle sleeve or severally can to regulate separately again, adjust the depth of parallelism of above-mentioned slide unit and guide rail sliding plate mating surface, to make this slide unit and guide rail sliding plate can realize laminating, ensure that slide unit carries out running stability when linear reciprocation moves along guide rail sliding plate to the full extent as far as possible.
As a kind of technology preferred version, the internal thread through hole quantity on above-mentioned machine tool body is three, and these three internal thread through hole are that product shape is arranged on machine tool body.
Above-mentioned further technology preferred version, according to the geometrical principle of " determining a plane at 3 ", when ensureing guide rail sliding plate stability, can reduce the production cost of slipway mechanism provided by the present invention to the full extent.
A kind of slipway mechanism that the present invention obtains, it uses on large automatic production equipment as transmission mechanism or transport establishment.Because the guide rail sliding plate in this slipway mechanism is relative to the distance of machine tool body, and the angle angle of this guide rail sliding plate himself and space basal plane all can regulate, therefore when equipment is installed or after equipment uses for a long time, the depth of parallelism of its slide unit and guide rail sliding plate fit clearance value between the two and both mating surfaces can be controlled all the time, guarantee that above-mentioned gap width remains on reasonable zones values, thus ensure the operation stability that slide unit structure is whole, extend the service life of slipway mechanism.
