Abstract
The invention relates to a gantry numerical control cutting machine positioning guiding structure. A roller is fixedly arranged on a rack body, the roller is connected with a roller shaft in a fitting way by virtue of a shaft sleeve, the two output ends of the roller shaft are connected with an insert bearing provided with a boss round base, and the insert bearing provided with a boss round base is connected and fixed with the rack body; the fixed shaft and essential shaft are respectively provided with a side roller, the side roller is internally provided with a bearing for guiding, and the side roller is connected with the rack body by virtue of nuts. The numerical control cutting machine of the invention adopts high strength positioning guiding structure, the insert bearing provided with boss round base and shaft are adopted to fixed the roller, the inner side and outer side are respectively clamped by the fixed shaft and essential shaft by virtue of the side roller, the rotation of the side roller is guided by the bearing, strength is improved, positioning is accurate, assembling is simple, and operation of machine is more stable and reliable; and the structure has high loading capacity and is perfect for high speed large span cutting equipment.
Description
Technical field
The present invention relates to a kind of gantry numerical control cutting machine high strength positioning and guiding mechanism, specifically be applied to the positioning and guiding mechanism in the Numerical control cutting equipment, belong to the cutting equipment technical field.
Background technology
At present, the positioning and guiding mechanism that uses in the Numerical control cutting equipment generally all is to use common radial bearing to make positioning and guiding; Loading end is less, rigidity a little less than, when the equipment high-speed cruising; Because rigidity is not strong; Be prone to produce jitter phenomenon, thereby influence the cut quality of equipment, therefore the positioning and guiding mechanism of numerical control cutting machine is only applicable to little span low speed cutting equipment at present.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, a kind of economy is provided, rigidity is strong, bearing capacity is big, positioning accuracy is accurate, assembling is easy, operate steadily, numerical control cutting machine positioning and guiding mechanism reliably.
According to technical scheme provided by the invention, said numerical control cutting machine positioning and guiding mechanism comprises Rack Body, axle sleeve, roller, roller shaft, band boss circular base spherical outside surface ball bearing, fixed axis, eccentric shaft, side wheel, bearing and nut; Be set with roller on the said Rack Body, described roller is connected through axle sleeve and roller shaft, and roller shaft two outputs are connected with band boss circular base spherical outside surface ball bearing, and band boss circular base spherical outside surface ball bearing is connected fixing with Rack Body; Difference installation side roller is equipped with bearing and leads on said fixed axis and the eccentric shaft in the side wheel, is connected with Rack Body through nut.
The outside is each one in the said band boss circular base spherical outside surface ball bearing, and big with the Rack Body contact-making surface, bearing capacity is big.
Compared with present technology the present invention has the following advantages:
Numerical control cutting machine high strength positioning guiding structure of the present invention adopts by band boss circular base spherical outside surface ball bearing and axle fixed idler whell; Inside and outside both sides are clamped through side wheel by fixed axis and eccentric shaft respectively, and the rotation of side wheel is led by bearing, gains in strength; Accurate positioning; Assemble easyly, mechanical movement is more steady, and is reliable; This structural loads ability is bigger, is the perfect structure of at a high speed big span cutting equipment.
Description of drawings
Fig. 1 is a front view of the present invention.
Fig. 2 is the view that attaches of the present invention.
Fig. 3 is a left view of the present invention.
The specific embodiment
Following the present invention will combine the embodiment of accompanying drawing to further describe:
Numerical control cutting machine high strength positioning guiding structure of the present invention mainly is made up of Rack Body 1, axle sleeve 2, roller 3, roller shaft 4, band boss circular base spherical outside surface ball bearing 5, fixed axis 6, eccentric shaft 7, side wheel 8, bearing 9, nut 10 etc.
Numerical control cutting machine high strength positioning guiding structure of the present invention; Be included in the roller 3 that fixedly installs on the Rack Body 1; Described roller 3 cooperates with roller shaft 4 through axle sleeve 2; 4 liang of outputs of roller shaft are connected with band boss circular base spherical outside surface ball bearing 5, and band boss circular base spherical outside surface ball bearing 5 is connected fixing with Rack Body 1.
Said fixed axis 6 and eccentric shaft 7 each installation side roller 8 are equipped with bearing 9 and lead in the side wheel 8, be connected with Rack Body 1 through nut 10.
The operation principle of the present invention and the course of work
Numerical control cutting machine high strength positioning guiding structure of the present invention mainly is employed in roller 3 is installed on the Rack Body 1; The installation of roller 3 is fixing through band boss circular base spherical outside surface ball bearing 5 by roller shaft 4; Note the symmetrical centre of roller 3 and Rack Body 1 during installation, can do repair through axle sleeve 2 and regulate the gap; Respectively adorning bearing 9 in the side wheel 8 puts in place fixing; The side wheel that installs bearing 98 respectively is contained on fixed axis 6 and the eccentric shaft 7; Guarantee to rotate flexibly; The both sides of Rack Body 1 install and fix the assembly of axle 6 and eccentric shaft 7 respectively, and the fixed axis side is fastened by nut 10 assemblies earlier, and eccentric shaft side adjustable eccentric amount is pieced together tight by nut 10 after itself and guide way are clamped again.
The present invention and transmission mechanism are supporting to be made as positioning and guiding.
