Abstract
The utility model belongs to the technical field of guide rail devices, and in particular relates to a reverser for a slider. The reverser for the slider can be used for solving the technical problems such as irrational existing design and difficulty in installation. The reverser for the slider comprises a body with two reversing channels, wherein one end of each reversing channel is an inlet end, while the other end of the same is an outlet end; the body comprises a first reversing part and a second reversing part, the two of which are locked with each other; a positioning sleeve located at the inlet end or the outlet end of the reversing channel is arranged on the body; two first semicircular bodies are correspondingly arranged on the first reversing part; second semicircular bodies in one-to-one correspondence to the first semicircular bodies are arranged on the second reversing part; a positioning sleeve is formed between the first semicircular bodies and the second semicircular bodies; and the perimeter of the first semicircular body is greater or less than that of the second semicircular body. The reverser for the slider has the advantages that the reversing channels in the reverser can be abutted with roll ball channels in the slider accurately and then the roll balls can be ensured to run steadily and smoothly.
Description
Technical field
The utility model belongs to track-type facilities technical field, especially relates to a kind of slide block reverser.
Background technique
Along with the development of Modern Manufacturing Technology, the positioning precision of mechanical transmission mechanism, guiding accuracy and feed speed improve constantly, and make traditional guide mechanism that great change occur.People, in continuous production practices, improve gradually to the accurate requirement of the slide block of linear guides pair.Conventionally in mechanical field, common linear guide pairs is by guide rail, slide block, back part, the compositions such as steel ball, back part by screw fastening at slide block two ends, then load onto steel ball and guide rail supports the use, miniature linear guide pairs is because the feature that it becomes more meticulous is widely used in precision measuremnt, detecting instrument, manipulator, on the categories such as clamp tool, highi degree of accuracy, high rigidity, lightweight, in the performance requirement industries such as low noise, more and more extremely value, in order to improve the packaging efficiency between reverser and slide block, for this reason, people have carried out long-term exploration, various solutions have been proposed.
For example, Chinese patent literature discloses a kind of precise rolling guiding rail pair [application number: 201120219961.3], there is guide rail, slide block, guide rail outer wall has 4 arc grooves, and slide block inwall has 4 arc grooves, and the arc groove of guide rail coordinates formation raceway with the arc groove of slide block, steel ball and retainer are installed in raceway, guide rail is connected by steel ball rolling with slide block, and described slide block end is provided with reverser, and reverser end is provided with dust sealing end cap.In addition, Chinese patent literature discloses a kind of linear movement guide device [application number: 01136282.0], it consists of track, slide block and rotor, the bi-side of its track on its length direction are provided with the 1st track ditch, this slide block carries out relative movement and has the 2nd track ditch arranging with described the 1st track ditch subtend on described track across frame, this rotor moves in an Infinite Cyclic route.
Above-mentioned scheme has improved packaging efficiency to a certain extent, but, also at least there is following defect in this two schemes: designs unreasonable, back passage in reverser docks and has deviation with the ball channel in slide block, cause ball operation not steadily with smooth and easy, virtually reduced slide block working stability, cannot meet and produce and usage requirement.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of and can make the back passage in reverser accurately dock with the ball channel in slide block, guarantees that ball operates steadily and slide block reverser smoothly.
For achieving the above object, the utility model has adopted following technical proposal: this slide block comprises the body with two back passages with reverser, one end of back passage is entrance point, the other end is outlet end, it is characterized in that, described body comprises the first back portion and the second back portion of mutual fastening, on body, be provided with and be positioned at the described entrance point of back passage or the setting sleeve of outlet end, in the first back portion, be provided with corresponding two the first semiround body that arrange, in the second back portion, be provided with and the first described semiround body the second semiround body one to one, and form above-mentioned setting sleeve between the first described semiround body and the second semiround body, the girth of the second semiround body is longer than or is shorter than to the girth of the first described semiround body.Obviously, the utility model design is more reasonable, can make the back passage in reverser accurately dock with the ball channel in slide block, guarantee that ball operates steadily with smooth and easy, in addition, has also improved packaging efficiency, reduced cost of production and shortened processing duration, having met the development trend of current social technology.
At above-mentioned slide block with in reverser, the first described back portion and the first semiround body formula that is connected as a single entity; The second described back portion and the second semiround body formula that is connected as a single entity.This structural strength is high, is difficult for damaged.
At above-mentioned slide block, with in reverser, described body is located by fixed structure.Be easy to install and location.
At above-mentioned slide block, with in reverser, described fixed structure comprises at least one fixed hole being arranged on body.
At above-mentioned slide block, with in reverser, described body is made of plastics.Low cost of manufacture and manufacturing efficiency are high.
Compared with prior art, this uses novel advantage to be: it is more reasonable to design, can make the back passage in reverser accurately dock with the ball channel in slide block, guarantee that ball operates steadily with smooth and easy, in addition, also improve packaging efficiency, reduced cost of production and shortened processing duration, met the development trend of current social technology.
