Abstract
The utility model discloses a straight line travelling mechanism. The mechanism is a lead screw nut driving mechanism. A nut is connected with back shafts through first adapting pieces. The two ends of each back shaft are provided with idler wheels. The idler wheels are matched with a supporting frame which is provided with a guide rail. The idler wheels can roll along the guide rail on the supporting frame. A base plate is arranged on the back shafts. A spray gun supporter is arranged on the base plate. An upper guide rail is also arranged on the idler wheels. The upper guide rail is connected with the supporting frame through second adapting pieces. The straight line travelling mechanism has the advantages of being simple in structure, convenient to use and reliable in use. Only the upper guide rail is added into the existing lead screw nut driving mechanism, and the straight line travelling mechanism enables the idler wheels to be clamped between the upper guide rail and a lower guide rail, thereby restraining shake generated in a transmission process, and therefore stable motion of a driven component is maintained, and also aggravation of abrasion is reduced.
Description
Technical field
The utility model relates to a kind of linear transmission mechanism, is specifically related to a kind of straight walking mechanism.
Background technique
In existing screw nut driven mechanism, generally be to drive leading screw by drive motor to rotate, do reciprocating linear motion by the dynamic load of nut band.Since between leading screw and the nut matching gap is arranged, the thereupon prolongation of service time, and it is large that its gap can become gradually.When driven load is larger, loads in the to-and-fro motion process and can produce shake or swing like this.So both affected the stability of load movement, the aggravation of also can wearing and tearing simultaneously forms vicious circle.Existing screw nut driven mechanism is difficult to satisfy simple in structure, with low cost, and transmission accuracy is higher, the demand of long service life.
The model utility content
The purpose of this utility model is to overcome the defective that exists in the prior art, and a kind of straight walking mechanism that prevents to shake is provided, and has characteristics simple in structure, with low cost.
For achieving the above object, the technical solution of the utility model is a kind of straight walking mechanism of design, it is characterized in that, described straight walking mechanism is the feed screw nut driving mechanism, described nut is connected with back shaft by the first link, two ends at described back shaft are provided with roller, described roller cooperates with the supporting frame that is provided with guide rail, described roller can roll along the guide rail on the supporting frame, be provided with base plate at described back shaft, be provided with the spray gun eyelid retractor at described base plate, also be provided with upper rail on described roller, described upper rail is connected with supporting frame by the second link.
Wherein preferred technological scheme is, described the first link has two, and the back shaft that is connected with described the first link has two.
Further preferred technological scheme is between described back shaft and roller bearing to be housed.
Further preferred technological scheme also has, and the cross section of support frame as described above is the C shape structure of opening upwards, and described guide rail is positioned at the two ends of C shape opening, and described feed screw nut is wrapped in the C shape structure.
Further preferred technological scheme also has, and described the second link has two at least.The adjustable linkage structure that is provided with between described the second link and supporting frame, described adjustable linkage structure is used for regulating the spacing between upper rail and the guide rail.
Further preferred technological scheme also has, and described adjustable linkage structure comprises that the slotted hole that is arranged on the second link connects the second link in the bolt of supporting frame with being connected.
Further preferred technological scheme also has, and the screw mandrel in the described feed screw nut driving mechanism is ball screw.
Advantage of the present utility model and beneficial effect are: this straight walking mechanism has simple in structure, the characteristics such as easy to use and reliable, this straight walking mechanism only adds in existing screw nut driven mechanism loads onto upper rail, roller is clamped between the upper/lower guide, thus the shake that can suppress to produce in the transmission process.So namely can keep the motion of driven device steady, the aggravation that can reduce wear again.
