Detailed Implementation

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example Reference Figures 1-4 This embodiment of the present invention provides a linear slide rail positioning device with a measuring function, comprising: The base plate 101, the bolts 102 threadedly connected to the surface of the base plate 101, the guide rail 103 threadedly connected to the surface of the base plate 101, the sliding assembly 104 slidably connected to the surface of the guide rail 103, the drive assembly 105 fixedly mounted on the surface of the sliding assembly 104, and the measuring assembly 106 rotatably connected to the end of the drive assembly 105. The sliding assembly 104 includes a rack 104a fixedly mounted on the inner wall of the guide rail 103, a slide plate 104b slidably connected to the surface of the guide rail 103, a mounting plate 104c disposed on the surface of the slide plate 104b, a motor 104d fixedly mounted on the surface of the mounting plate 104c, a gear 104e sleeved on the output end of the motor 104d, and a roller 104f fixedly mounted on the bottom of the slide plate 104b.

[0019] Specifically, gear 104e meshes with the surface of rack 104a, and roller 104f slides on the surface of guide rail 103.

[0020] Among them, the starter motor 104d, whose output shaft drives the gear 104e to rotate, and the gear 104e drives the entire slide plate 104b to move linearly along the guide rail 103 through the rack 104a, while driving the eccentric wheel 105a to rotate synchronously.

[0021] Furthermore, the drive assembly 105 includes an eccentric wheel 105a sleeved on the output end of the motor 104d, a limiting block 105b fixedly installed on the surface of the slide plate 104b, a piston rod 105c slidably connected to the inner wall of the limiting block 105b, and a spring 105d sleeved on the surface of the piston rod 105c.

[0022] One end of the piston rod 105c is disposed on the surface of the eccentric wheel 105a, and the other end of the piston rod 105c is movably connected to the side wall of the pull rod 106b. The rotational movement of the eccentric wheel 105a pushes the piston rod 105c to reciprocate linearly within the limiting block 105b. The spring 105d ensures that the end of the piston rod 105c always remains in contact with the surface of the eccentric wheel 105a, thus controlling the reciprocating movement of the piston rod 105c.

[0023] Preferably, the measuring assembly 106 includes a shaft block 106a fixedly mounted on the surface of the slide plate 104b, a pull rod 106b rotatably connected to the axis of the shaft block 106a, a pawl 106c movably connected to the end of the pull rod 106b, a ratchet 106d sleeved on the axis of the shaft block 106a, and a measuring display 106e sleeved on the axis of the shaft block 106a, wherein the pawl 106c engages with the surface of the ratchet 106d.

[0024] It should be noted that the pull rod 106b drives the pawl 106c at its end to swing. When the pawl 106c swings forward, it pushes the ratchet 106d to rotate one tooth. When it returns, it slides over the back of the teeth of the ratchet 106d. The rotation of the ratchet 106d is collected by the coaxial measuring display 106e. Through a reasonable transmission ratio design, the reading on the counter can directly and accurately reflect the actual linear displacement of the slide plate 104b relative to the guide rail 103.

[0025] In use, the motor 104d is started, and its output shaft drives the gear 104e to rotate. The gear 104e drives the entire slide plate 104b to move linearly along the guide rail 103 through the rack 104a, and at the same time drives the eccentric wheel 105a to rotate synchronously. The rotational motion of the eccentric wheel 105a pushes the piston rod 105c to reciprocate linearly within the limit block 105b. The spring 105d ensures that the end of the piston rod 105c always maintains contact with the surface of the eccentric wheel 105a. The reciprocating motion of the piston rod 105c, through its interaction with the pull... The connection point of rod 106b is converted into the reciprocating swing of pull rod 106b around shaft block 106a. Pull rod 106b drives the pawl 106c at its end to swing. When the pawl 106c swings forward, it pushes ratchet 106d to rotate one tooth. When it returns, it slides over the back of the tooth of ratchet 106d. The rotation of ratchet 106d is collected by coaxial measurement display 106e. Through reasonable transmission ratio design, the reading on the counter can directly and accurately reflect the actual linear displacement of slide plate 104b relative to guide rail 103.

[0026] In summary, the sliding component 104 enables the slide plate 104b to slide along the guide rail 103; the combined use of the transmission component and the measuring component 106 enables the reciprocating linear motion to drive the rotation of the ratchet 106d; the mutual cooperation between the sliding component 104 and the measuring component 106 enables the device to convert the number of teeth of the gear 104e into a linear displacement distance that can be read on the measuring display 106e. The device is simple and efficient to operate, effectively solving the problem of requiring complex procedures such as sensors to perform linear displacement measurement.
