Description
Technical field
The invention relates to a kind of rolling module holding device, it applies in the slide block of straight line transmitting assemblies, and this holding device can keep the orientation of the inner rolling module of slide block, also can provide the smooth-going backflow of rolling element of backflow to roll; Generally speaking the straight line transmitting assemblies is to be applied in the mechanisms such as toolroom machine, electronics, automation equipment, semiconductor equipment.
Background technique
In the straight line transmitting assemblies of known techniques, its rolling module is made up of the structures such as coupling chain of rolling element, the interval body that separates rolling element and binding interval body, so the guide device that refluxes must cooperate the appearance profile of rolling module, and following several design is generally arranged; First kind is designed to integrated individual construction such as U. S. Patent No. 5755516, the structure that backflow guide device wherein is one of the forming, because the complicated injection molding method for making of using usually of its structure, and must consider the fit tolerance problem of backflow guide device and slide block, the degree of difficulty of therefore should the backflow guide device controlling the contraction deformation amount increases.Moreover this backflow guide device is a reflow pipe of offering hollow in individual construction, make the rolling module must be by to finish backflow, this structure makes the area of contact of rolling module and reflow pipe quite big, is easy to generate bigger surface friction drag, influences the smoothness that the rolling module refluxes.
Second kind of guide device design then is No. the 6524003rd, two-piece type structure such as U. S. Patent, it is the synthetic tubular bodies of two semicanal structures, though the contraction deformation problem of this design plastics injection molding can be so unobvious as integrally formed structure, but have the problem of contraction deformation because of structure is more elongated, and the tolerance of size restriction that has two semicanal structures to arrange in pairs or groups each other and cooperate with the slide block hollow hole etc., so it is made relative degree of difficulty is arranged.Adding this guide device is to guide the rolling module in the mode of surrounding the rolling module equally, makes area of contact between the two quite big, is easy to generate bigger surface friction drag, influences the smoothness that the rolling module refluxes.
The third is designed to half slice structure such as U. S. Patent No. 6203199, this design class is like second kind of design, only this structure only coats one side of something of rolling module, lower wall restriction rolling module in the utilization, generally speaking the mode of plastic shaping is also used in this design, so equally also have the problem of contraction deformation and the problem that area of contact is easy to generate big surface friction drag greatly.Moreover the contraction deformation amount is put in order stuck can't the running of group straight line transmitting assemblies if the improper meeting of control causes size error and the guide device generation interference of rolling module and this backflow, severe patient can be allowed.
Comprehensively above-mentioned, the real necessity that has urgent improvement to progress greatly of the rolling module holding device of prior art.
Summary of the invention
Purpose of the present invention promptly is to provide a kind of rolling module holding device, and it can reduce surface friction drag makes smooth-going ground of rolling module reflux cycle, the rolling module is remained in the default orientation reflux.
The present invention at first considers how to utilize limited backflow space, improves the big shortcoming of area of contact in the old technology; So utilization circular contour and polygonal profile or circular contour and the little notion of circular contour surface of contact develop the roll contact profile of module holding device of the present invention.Known techniques is recessed structural design, coats the rolling module and guides the backflow of rolling module with the arc profile; But the present invention adopts projective structure design, withstands the rolling module and guides the rolling module and reflux with the outer margin contour of circle or polygonal external diameter, area of contact can be dwindled and reduces surface friction drag, makes smooth-going ground of rolling module reflux cycle.
The design concept that the present invention adopts circular contour to contact with circular contour or polygonal profile, in return port, insert the club shaped structure of circular contour or polygonal profile, make the backflow space form the designed guiding space of the present invention, allow the rolling module be guided and in default orientation, reflux.
Club shaped structure of the present invention can be divided into modular construction designs such as single contact, two contact and many contacts; Two contacts wherein and design of many contact structures can be made of single contact assembly of plural number or integrated assembly forms.And holding device means of fixation of the present invention can be made the groove or the salient point of secure fit on the accessory at slide block two ends, and is fixed on this accessory; The also groove or the salient point that can cooperate in the both ends of the surface designs fix of slide block, and holding device is fixed on the slide block.
In addition,, also can utilize the mode of the direct deflection moulding of metal bar to make, therefore can make manufacture cost certain degree ground get reduction because the simple structure of holding device of the present invention can be utilized general shoot mode manufacturing.
Further understand feature of the present invention and technology contents for convenience, please consult following relevant embodiments of the present invention in detail, however this mode of execution and graphic only for explanation and with reference to usefulness, but not in order to the present invention is done any restriction.
