The present invention is to provide a slide track structure of a linear platform, wherein the center of gravity of the slide track structure of the linear platform may be lowered. In addition, the outer edge of the upper end of the U-shaped guide track is formed with an inclined face or a smooth arc-shaped face, thereby capable of producing better structural stiffness, saving material, and decreasing weight. Thus, the slide track structure of the linear platform of the present invention can increase the structural stiffness, save material, and decrease the entire weight.

Slide track structure of a linear platform

A linear guide way structure. The structure utilizes spring strips to combine a sliding body assembly and end caps, instead of using screws or pins. The sliding body assembly and the end caps are combined together with an almost constant resilient force provided by the spring strips whose mechanical strength is greater than that of plastic material. The problem of exfoliation between two physically different materials such a metal and plastic never is avoided. Accordingly, the linear guide way is easy to fabricate, operate, and maintain with low cost.

Linear guide way

A linear guide way structure comprises a guide rail, a slider, and two end cups. The slider has two ends each defining a ball return hole having a first-end-opening, and a ball groove having a second-end-opening. The adjustable end cup is provided with two ball direction changing paths each having a first-mating-end-opening abutting the first-end-opening of the ball return hole, and a second-mating-end-opening abutting the second-end-opening of the ball groove. The adjustable end cup is provided with a plurality of adjusting slits, and at least one of the adjusting slits has a determined depth so that the adjustable end cup is made flexible, thereby adjusting the distance between the two first-mating-end-openings of each of the two ball direction changing paths of the adjustable end cup, so that the first-mating-end-opening can be exactly engaged with the first-end-opening of the ball return hole.

Adjustable end cup for linear guide way structure

A measurable guide actuator is used to integrate a driving mechanism, a guide mechanism, and a position measuring member so as to form an integral simplifying construction, thereby facilitating the usage and thereby reducing consumption of material. The measurable guide actuator of the present invention uses a U-shaped guide track to function as the guide mechanism. The driving mechanism uses a screw or a belt. The position measuring member includes a ruler body mounted in the guide mechanism, and a reading head sealed in the sliding table to slide therewith so that the position measuring member can be used to measure the displacement position values.

Measurable guide actuator

A linear guide apparatus with magnetic distance sensor is disclosed. A magnetic tape is adhered right on the upper surface of the guide rail so as to minimize the variation of distance between the magnetic tape and a magnetic induction element to assure high distance sensing sensitivity when the slide block is exerted by a transverse thrust force. The magnetic tape can be adhered to the upper surface of the guide rail after the guide rail has been assembled to its base thereby facilitating the assembly work. The magnetic induction element is installed in an end cap of the slide block so that it is not necessary to modify the construction of the inner part of the slide block. As a result, the space is saved and the mechanical strength of the apparatus is increased. In order to reduce the influence of magnetic field induced by the electric current flowing in the power supply lines of the apparatus on the sensor signal, an outlet terminal block is provided on a side surface of the slide block so as to prevent the signal wires from passing through right over the magnetic tape thereby protecting the sensor signal from interference.
