Abstract
The invention discloses a positive/negative thread positioning mechanism which comprises a bracket, a positioning block, a positive/negative thread pin and a guide rail. According to the invention, the positive/negative thread pin passes through the bracket and is connected with the positioning block through a thread structure on the bracket; and the positive/negative thread pin can rotate in the bracket, wherein the position of the positive/negative thread pin relative to the bracket is not changed during the rotation. Thus, when the positive/negative thread pin is rotated, the positioning block can be controlled to slide back and forth along the guide rail so as to conveniently position and remove the product.
Description
Technical field
The present invention relates to a kind of positive left-hand thread detent mechanism, particularly relate to a kind of locating piece that can control on it and move forward and backward the positive left-hand thread detent mechanism that product is positioned and dismantles with convenient.
Background technology
Manufacturing and designing in the process of car load group model for the car load group model reliable in quality that guarantees that final production goes out, needs each spare and accessory parts in the car load group model are carried out quality testing and control in process of production.Therefore, need some cubings of design and relevant servicing unit thereof, and each spare and accessory parts in the car load group model are carried out check measurement targetedly by their cooperation.Therefore, in manufacturing and designing the process of above-mentioned cubing, when needing to consider the application of measuring method and survey tool, also need to consider the design of the relevant servicing unit of cubing, such as when using positioner to carry out product orientation, all there is a common problem in traditional positioner: be exactly the total more complicated, and operation inconvenience.
In sum, problem demanding prompt solution is that needs design a kind of detent mechanism that is used for car load group model manufacture process, and are not only simple to operate when it positions each spare and accessory parts in the car load group model, and will locate reliable; In addition, this positioner can be taken off spare and accessory parts after spare and accessory parts complete easily from this positioner.
Summary of the invention
Technical problem to be solved by this invention is, a kind of positive left-hand thread detent mechanism is provided, when it can position each spare and accessory parts in the car load group model, and simple to operate, the location is reliable.Simultaneously, this positioner can be taken off spare and accessory parts after spare and accessory parts complete easily from this positioner.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of positive left-hand thread detent mechanism, this detent mechanism comprises: support, locating piece, positive and negative threaded and guide rail, wherein, described positive and negative threaded passes described support and is connected with described locating piece by the helicitic texture on it, when described positive and negative threaded can rotate in described support and rotate and the relative position between the described support do not change, described locating piece can slide along described guide rail when described support rotated, and described support is provided with the product hook and is used for fixing the product that is positioned.
Further, in the positive left-hand thread detent mechanism of the present invention, comprise at least two guide rails.
Advantage of the present invention is, among the present invention, described positive and negative threaded passes described support and is connected with described locating piece by the helicitic texture on it, when described positive and negative threaded can rotate in described support and rotate and the relative position between the described support do not change.Therefore can control described locating piece when rotating described positive and negative threaded carries out front and back slip along described guide rail and to make things convenient for product is positioned and dismantles.
Description of drawings
Fig. 1 is the overall structure schematic diagram of the positive left-hand thread detent mechanism of the present invention;
Fig. 2 is the side sectional view of the positive left-hand thread detent mechanism of the present invention;
Fig. 3 is the internal view of the positive left-hand thread detent mechanism of the present invention.
The specific embodiment
For further disclosing technical scheme of the present invention, be described with reference to the accompanying drawings embodiments of the present invention now.
Fig. 1 is the overall structure schematic diagram of the positive left-hand thread detent mechanism of the present invention, Fig. 2 is the side sectional view of the positive left-hand thread detent mechanism of the present invention, Fig. 3 is the internal view of the positive left-hand thread detent mechanism of the present invention, by above accompanying drawing as can be known, the present invention includes: support 110, locating piece 120, positive and negative threaded 130, and guide rail 121, wherein, described positive and negative threaded 130 passes described support 110 and is connected with described locating piece 120 by the helicitic texture 122 on it, when described positive and negative threaded 130 can rotate in described support 110 and rotate and the relative position between the described support 110 do not change, described locating piece 120 can slide along described guide rail 121 when described support 110 rotated, and described support 110 is provided with product hook 123 and is used for fixing the product that is positioned.In addition, in order to improve the accuracy to car load group model spare and accessory parts location, this positive left-hand thread detent mechanism comprises at least two guide rails 121, makes described locating piece 120 to slide along the track that described guide rail 121 is set.
Below in conjunction with the course of action of description of drawings the present invention when carrying out actual location.
During the location, rotate described positive and negative threaded 130, the track that described locating piece 120 is set along described guide rail 121 slides, make the product hook 123 on the described locating piece 120 hook the product 200 of mending the location by the position of adjusting described locating piece 120, so far, complete location to the product 200 that is positioned; After the detection of the product 200 that is positioned finished, rotate described positive and negative threaded 130 once more, make that the product hook 123 on the described locating piece 120 breaks away from the product 200 that is positioned, can be easily take off the product 200 of being positioned this moment from this detent mechanism.
More than, the basic ideas and basic principles of the present invention have been set forth by description of listed embodiment.But the present invention never is limited to above-mentioned listed embodiment, and every equivalent variations, improvement and deliberately of inferior quality behavior of doing based on technical scheme of the present invention of change all should belong to protection scope of the present invention.
