Abstract
A sliding table includes a sliding seat having a seat body made from a first material and disposed between two main rigid rails parallel with each other. The seat body has two opposite rail recesses opening toward the main rigid rails, and two inner cyclic track holes disposed between the rail recesses. Two seat body rigid rails made from a second material harder than the first material are fixed in the rail recesses to confront the main rigid rails. Two roller belt modules are arranged in two cyclic track members overmolded to the seat body. When the seat body moves along the main rigid rails, each roller belt module circulates along one of the cyclic track members.
Claims11
A sliding table, comprising:
- two main rigid rails extending along a lengthwise direction of the sliding table and parallel with each other;
- a screw rod extending along the lengthwise direction and disposed between said main rigid rails;
- a sliding seat including
- a seat body made from a first material and disposed between said main rigid rails, said seat body having a driving hole through which said screw rod extends, two opposite sides respectively formed with rail recesses which open respectively toward said main rigid rails, and two inner cyclic track holes each of which is disposed between said driving hole and one of said rail recesses,
- two seat body rigid rails made from a second material harder than the first material, and respectively fixed in said rail recesses to respectively confront said main rigid rails,
- two cyclic track members overmolded to said seat body, each of said cyclic track members having an outer track section extending along one of said rail recesses and uncovering one of said seat body rigid rails fixed to said one of said rail recesses, an inner track section formed in one of said inner cyclic track holes, and two turnaround sections respectively disposed at two opposite ends of said outer track section, each of said turnaround sections connecting between one of said two opposite ends of said outer track section and one of two opposite ends of said inner track section, and
- two roller belt modules respectively arranged in said cyclic track members, each of said roller belt modules including a belt made of a flexible material, and a plurality of rollers held by said belt at intervals;
- wherein, when said seat body moves along said main rigid rails, each of said roller belt modules circulates along one of said cyclic track members by sequentially passing said outer track section, one of said turnaround sections, said inner track section, and the other one of said turnaround sections of said one of said cyclic track members;
- and
- wherein said rollers of each of said roller belt modules roll between one of said main rigid rails and one of said seat body rigid rails, while said belt of each of said roller belt modules slides along said outer track section of one of said cyclic track members.
