Abstract
The invention relates to a machine tool with a gantry structure, and mainly solves the stress deformation problem caused by thermal expansion of a cross beam of the machine tool in the prior art. The machine tool with the gantry structure comprises pin slot structure based cross beam expansion joints. The expansion joint is of a pin slot structure, and one end of a cross beam is fixedly connected; the other end of the cross beam is flexibly connected, and one or more guide grooves are fixedly arranged on the cross beam; and the direction of the guide groove is the same as that of the cross beam, and one or more pins matched with the guide grooves is or are fixedly arranged on columns. When the cross beam is heated to expand, pins slide in pin slots to absorb the amount of deformation caused by expansion of the cross beam, and the structure vertical to the cross beam direction can keep the original relative position of the cross beam. The technical scheme better solves the problem and can be used in the industrial production of the machine tool with the gantry structure.
Description
Technical field
The present invention relates to a kind of gantry structure lathe, particularly contain Longmen machine tool based on the crossbeam expansion joints of cotter way structure.
Background technology
In the gantry structure lathe, crossbeam is high-precision structural member.The lathe size of gantry structure is bigger usually, and adopts metal material to make.Conventional engineering material all has the problem of expanded by heating distortion, as the typical steel heat coefficient of expansion is 10 * 10-6m/m* ℃, the coefficient of expansion of aluminium alloy is 22 * 10-6m/m* ℃, under the condition of 1 degree centigrade of the every rising of temperature, 1 meter long steel crossbeam expands 10 microns, and 1 meter long aluminium alloy crossbeam expands 22 microns.Crossbeam expands must cause corresponding stress deformation problem, causes the structural member precision to change or the way rub aggravation, and the life-span descends.For head it off, a kind of crossbeam expansion joints based on the cotter way structure is proposed.
The invention provides a kind of crossbeam expansion joints, be applicable to the gantry structure lathe, solve the stress deformation problem that the lathe crossbeam expands and causes based on the cotter way structure.
Summary of the invention
Technical problem to be solved by this invention is the corresponding stress deformation of Longmen machine tool crossbeam expansion causing in the prior art, cause the structural member precision to change or the way rub aggravation, the problem that the lathe life-span descends, a kind of new gantry structure lathe is provided, and this lathe crossbeam expansion joints has the advantage that can absorb the stress deformation that the crossbeam expanded by heating causes.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows: a kind of gantry structure lathe, comprise pedestal, crossbeam, left column, right column, affiliated crossbeam has expansion joints, described bloated joint is the cotter way structure, described cotter way structure is connected the end of crossbeam, crossbeam is fixed on the column, crossbeam has the end of cotter way structure for flexibly connecting, the other end is fixedly connected, it is identical with the crossbeam length direction to fix one or more guide groove directions on the crossbeam, cooperates the crossbeam guide groove to fix one or several pins on the column; Described crossbeam is along crossbeam parallel direction contraction or expansion the time, and the cotter way generation relatively moves along the crossbeam parallel direction, absorbs the deformation quantity that the crossbeam contraction or expansion causes.
Crossbeam expansion joints based on the cotter way structure, described bloated joint is the cotter way structure, described cotter way structure is connected the end of crossbeam, crossbeam is fixed on the column, crossbeam has the end of cotter way structure for flexibly connecting, the other end is fixedly connected, and it is identical with the crossbeam length direction to fix one or more guide groove directions on the crossbeam, cooperates the crossbeam guide groove to fix one or several pins on the column; Described crossbeam is along crossbeam parallel direction contraction or expansion the time, and the pin generation relatively moves along the crossbeam parallel direction, absorbs the deformation quantity that the crossbeam contraction or expansion causes.
