Description
Technical Field
[0001] The utility model relates to the technical field of optical motor guide rails, in particular to an optical motor guide rail with a simple structure. Background Art
[0002] Optical motor guides are often used in optical experiments. As for optical motor guides, currently, such guides on the market are generally made by injection molding. For example, the authorization announcement number CN217355241U discloses an improved optical motor guide rail, which specifically discloses a fixed guide rail assembly, a sliding guide rail assembly and a ball bearing that cooperate with each other; the fixed guide rail assembly includes a fixed guide rail seat and two first metal inlaid shafts; a first rolling groove is arranged on the top surface of the fixed guide rail seat, and the two first metal inlaid shafts are symmetrically embedded in the two side walls of the first rolling groove, and the upper ends of the two first metal inlaid shafts protrude upward from the wall surface of the first rolling groove to form two first contact portions; the sliding guide rail assembly includes a sliding guide rail seat and two second metal inlaid shafts; a second rolling groove is arranged on the bottom surface of the sliding guide rail seat, and the two second metal inlaid shafts are symmetrically embedded in the two side walls of the second rolling groove, and the lower ends of the two second metal inlaid shafts protrude downward from the wall surface of the second rolling groove to form two second contact portions; the ball bearing is installed between the first rolling groove and the second rolling groove, and the outside is respectively pressed against the two first contact portions and the two second contact portions; the fixed guide rail seat and the sliding guide rail seat are both made of plastic.
[0003] However, there is still room for improvement in the above-mentioned improved optical motor guide. For example, since the ball in the above-mentioned optical motor guide slides between the fixed guide assembly and the sliding guide assembly and multiple ball bearings are generally installed during use, specifically, the ball bearings are installed between the first rolling groove and the second rolling groove and the outside is respectively pressed against the two first contact parts and the two second contact parts. However, since the contact between the outer wall surface of the ball bearings and the first contact part and the second contact part is point contact, this contact mode will cause dents on the surface of the first metal-mounted shaft and the second metal-mounted shaft due to the pressure and impact of the ball bearings during long-term use, so that the accuracy and stability of the optical motor guide cannot be guaranteed. In addition, since the above-mentioned improved optical motor guide requires multiple ball bearings, its overall structure still has the disadvantage of being more complicated, which in turn leads to a higher overall assembly cost and lower assembly efficiency.
[0004] Therefore, it is necessary to improve the existing technology. Utility Model Content
