Abstract
The utility model relates to a precision guide rod, which is provided with a rod body. One end of the rod body is provided with a spline connecting part; the end face of the spline connecting part is provided with a thread positioning hole; and the other end of the rod body is provided with a conical surface connecting part and a thread locking part. One end of the guide rod is connected with a transmission part through the spline connecting part, and the other end of the guide rod is connected with a transmission part through the conical surface connecting part, so that the coaxiality of the transmission parts at the two ends of the guide rod can be effectively ensured to improve transmission precision; meanwhile, the rod body is provided with a clamping spring groove, so that the axial displacement of a bearing arranged on the rod body can be effectively prevented, and the guide rod has high practicability.
Description
Technical field
The utility model relates to a kind of mechanical transmission component, particularly a kind of accurate guide rod.
Background technique
In the mechanical transmission mechanism, often need be with the transmission of the long distance of running torque, as main shaft of lathe, numerical control machining center or the like, this length is exactly guide rod apart from one of critical piece of carry-over moment, because guide rod is comparatively elongated comparatively speaking, how the transmittance process in moment guarantees that the coaxality at guide rod two ends just seems particularly important so.
The model utility content
The purpose of this utility model provides and a kind ofly can guarantee guide rod two ends coaxality, the effective accurate guide rod of transmission of torque.
The technological scheme that realizes the utility model purpose is: a kind of accurate guide rod, have the body of rod, and an end of the described body of rod has the spline joint, and spline joint end face is provided with the screw thread positioning hole, and the other end of the body of rod has conical surface joint and screw-threaded coupling portion.
The body of rod of above-mentioned accurate guide rod is provided with the jump ring groove.
The utlity model has positive effect: the utility model guide rod one end is connected with transmission part by the spline joint, the other end is connected with transmission part by conical surface joint, can effectively guarantee the coaxality of guide rod two ends transmission part, thereby improve the precision of transmission, the body of rod is provided with the jump ring groove simultaneously, can effectively prevent to be installed in the bearing axial displacement on the body of rod, practical.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and according to specific embodiment also in conjunction with the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is a structural representation of the present utility model.
Embodiment
See Fig. 1, the utlity model has the body of rod 1, an end of the body of rod 1 has spline joint 2, and spline joint 2 end faces are provided with screw thread positioning hole 3, and the other end of the body of rod 1 has conical surface joint 4 and screw-threaded coupling portion 5, and the body of rod 1 is provided with jump ring groove 6.
Above-described specific embodiment; the purpose of this utility model, technological scheme and beneficial effect are further described; institute is understood that; the above only is a specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
