Abstract
The utility model relates to an integrated guide rail sealing linear stepping performer which includes a lead screw motor. The output screw of the motor engages with the thread of a guiding slide nut. A client mounting shaft has an interference fit with a mounting hole of the guiding slide nut. Two fixing pins fix the client mounting shaft and the guiding slide nut. The performer is characterized in that the performer has a circular integrated guide rail section bar; the guiding slide nut is sleeved inside the guide rail section bar; and a sliding edge on the periphery of the guiding slide nut can slide along an inner slide rail edge of the guide rail section bar. Since a fixing support and the guide rail are integrated into an integrally formed integrated guide rail section bar, the precision of the stepping motor performer is enhanced, the installation procedure, the manufacturing difficulty and the cost are reduced, but the service lifetime is prolonged.
Description
Technical field
The utility model is specifically related to a kind of parts of stepping motor, particularly a kind of integrated guide rail canned linear stepping actuator.
Background technology
Prior motor straight-line transmitting dynamic model group as shown in fig. 1, be by a lead screw motor 100, mounting bracket 200 and guide rail 300 (or guide pillar) assemble, motor and line slideway (guide pillar) are fixed on the mounting bracket, the screw rod of motor or nut are fixedly connected on the slide block of guide rail (guide pillar), and the rotation of motor by screw rod promotes the slide block of guide rail and do rectilinear motion.But the parts of existing motor straight-line transmitting dynamic model group are too many, and the parts accumulated error is too big; Simultaneously each parts all is by assembling, the depth of parallelism of each parts after the assembling, and linearity, concentricity and perpendicularity can't be guaranteed, and cause the position degree of the screw rod of motor and guide rail (guide pillar) bad, influence
Noise and stuck phenomenon vibrations appear, in the overall performance of entire module and precision.Simultaneously, because screw rod, nut and guide rail all are exposed to the outside, are easy to be subjected to the pollution of dust, reduce the useful life of product.
Summary of the invention
The utility model provides a kind of integrated guide rail canned linear stepping actuator, and purpose is to solve the prior art problem, provides a kind of raising whole precision, the stepping motor actuator that reduces assembly process and manufacture difficulty and increase the service life, reduce cost.
The utility model technical scheme that adopts of dealing with problems is:
Integrated guide rail canned linear stepping actuator, include the screw mandrel stepping motor, screw-threaded engagement in the output screw of motor and the guiding sliding nut, the installing hole interference fit of client's installation shaft and guiding sliding nut, two holding pins are fixed client's installation shaft and guiding sliding nut.Have annular integrated guide rail section bar, the guiding sliding nut is placed in the guide rail section, and can slide along the interior slide rail limit applying of guide rail section in guiding sliding nut periphery slip limit.
The beneficial effects of the utility model: the integrated guide rail section bar that in the utility model fixed support and guide rail is integrated into a global formation, with the guiding of fixed support and slide rail with prevent that the function of rotating is integrated in one, improve the precision of entire module greatly, reduced assembly process and manufacture difficulty.Save rail plate, reduced cost.Simultaneously with guide rail, screw rod and nut all are sealed in integrated guide rail section bar the inside, have avoided screw rod, nut and guide rail to be subjected to the pollution of dust, the useful life of having improved entire product.
Description of drawings
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is an explosive view of the present utility model;
Fig. 3 is a constitutional diagram of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described further.
Integrated guide rail canned linear stepping actuator as shown in Fig. 2, Fig. 3, include screw mandrel stepping motor 1, flange hole on motor locating flange 10 and the mounting flange plate 2 cooperates, and the mounting flange hole on the mounting flange plate 2 and the inner chamber installing hole of annular integrated guide rail section bar 4 cooperate.Screw-threaded engagement in the output screw 11 of motor 1 and the guiding sliding nut 3, guiding sliding nut 3 is placed in the guide rail section 4, and can slide along interior slide rail limit 40 applyings of guide rail section 4 in guiding sliding nut 3 periphery slip limits 30.The installing hole (not shown) interference fit of client's installation shaft 7 and guiding sliding nut 3, two holding pins are fixing with client's installation shaft 7 and guiding sliding nut 3.The other end of client's installation shaft is supported and guiding by lining 5, and lining 5 is fixed on the flange internal control the inside of client's mounting panel 6 with built-in jump ring (not shown) by the hole.
When motor moves, screw mandrel stepping motor 1 drives screw rod 11 and rotates, screw rod 11 drives the slideway the inside of guiding sliding nuts 3 integrated slide rail section bar 4 in and does linear movement, drives the load that the client's installation shaft 7 that is installed on the sliding nut 3 that leads drives the client and does straight-line purpose to reach.
Integrated guide rail section bar 4 has adopted the technology of global formation, dimensional accuracy is greatly improved, with the guiding of fixed support and slide rail and prevent that the function of rotating is integrated in one, improve the precision of entire module greatly simultaneously, reduced assembly process and manufacture difficulty.Save rail plate, reduced cost.
Guiding sliding nut 3 is by high strength, and the engineering plastics of strong resistance to wear and band self-lubricating are injection molded, and the function of guide runner and transmission nut is designed to one, has not only reduced cost, and has improved the product precision.
The utility model is with guide rail, and screw rod and nut all are sealed in integrated guide rail section bar 4 the insides, as shown in Figure 3, has avoided screw rod 11, nut 3 and guide rail to be subjected to the pollution of dust, the useful life of having improved entire product.
