[0029] Example

[0030] like Figures 1 to 5As shown, the present invention provides an arc-shaped guide rail, mainly comprising a base 100, a guide rail 200, and a slide assembly 300. The guide rail 200 is fixedly mounted on the upper end of the base 100, and the slide assembly 300 is movably connected to the guide rail 100. The slide assembly 300 includes a slider 310, a pulley 320, and a rolling plunger assembly 330. The rolling plunger assembly 330 is nested and fixed on the slider 310. The rolling plunger assembly 330 includes a pin 331, a bushing 332, a spring 333, a bearing 334, a bearing rod 335, an open retaining ring 336, a limiting seat 337, a limiting plate 338, and a photoelectric switch 339.

[0031] Specifically, such as Figures 1 to 5 As shown, the base 100 has an arc-shaped structure. The upper surface of the inner end of the arc of the base 100 is provided with several limiting grooves 100.1. The limiting grooves 100.1 are rectangular and have chamfers 100.2. The center line of the limiting grooves 100.1 points to the center of the arc-shaped base. The width of the limiting grooves 100.1 is smaller than the outer diameter of the bearing 334.

[0032] Specifically, such as Figures 1 to 3 As shown, a number of bolt mounting holes 401.1 are provided at the intersection of the arc-shaped guide rail base 100 and the guide rail 200. The guide rail 200 is fixedly connected to the base 100 by bolts 401.

[0033] Specifically, such as Figures 1 to 3 As shown, the arc-shaped guide rail 200 has a T-shaped cross-section, that is, the upper end of the guide rail 200 has V-shaped protrusions 200.1 on both sides. The arc-shaped guide rail slider 310 is equipped with four pulleys 320. The arc-shaped guide rail pulleys 320 have V-shaped grooves 320.1, which cooperate with the V-shaped protrusions 200.1 on both sides of the upper end of the guide rail 200. Every two pulleys 320 perpendicular to the direction of movement form a group. Each pulley group can rotate along the arc-shaped guide rail 200 and drive the slider 310 and the rolling plunger assembly 330 to slide on the arc-shaped guide rail 200.

[0034] Specifically, such as Figures 1 to 3 As shown, the arc-shaped guide rail slider 310 is provided with a through hole 310.1 and a screw mounting hole 402.1. The arc-shaped guide rail bushing 332 is nested on the slider 310 through the through hole 310.1 and is fixedly connected by screws 402.

[0035] Specifically, such as Figures 1 to 5As shown, the arc-shaped guide pin 331 has a shaft platform 331.1, and the arc-shaped guide spring 333 is a compression spring. The inner diameter of the arc-shaped guide bushing 332 is larger than the diameter of the pin 331 and smaller than the outer diameter of the spring 333. The arc-shaped guide pin shaft platform 331.1 is larger than the outer diameter of the spring 333 and smaller than the through hole 320.1 of the slider. The body of the arc-shaped guide pin 331 is fitted into the spring 333. The pin 331 and the spring 333 pass through the lower end of the bushing 332. The lower end face of the bushing 332 and the pin shaft platform 331.1 are aligned with the spring 333. The arc-shaped guide rail spring 333 is in a compressed state when the limit is formed. The upper end of the arc-shaped guide rail pin 331 is also provided with a screw hole 331.2. The arc-shaped guide rail limit seat 337 is provided with a limit step 337.2. The lower end of the limit seat 337 is provided with a screw 337.1. The arc-shaped guide rail pin screw hole 331.2 and the limit seat screw 337.1 are installed together. At the same time, the limit seat 337 limits the pin 331 to the bushing 332 through the limit step 337.2. The pin 331 can slide up and down in the bushing 332.

[0036] Specifically, such as Figures 1 to 5 As shown, the lower end of the arc-shaped guide rail pin 331 is also provided with a groove 331.3, two mounting planes 331.4 and two bearing fixing through holes 331.5. The two mounting planes 331.4 are parallel to the groove 331.3, and the two bearing fixing through holes 331.5 are perpendicular to the two mounting planes 331.4. The arc-shaped guide rail bearing rod 335 is provided with a slot 335.1. The arc-shaped guide rail bearing 334 is installed in the pin groove 331.3 through the bearing fixing through hole 331.5 via the bearing rod 335. The arc-shaped guide rail open retaining ring 336 is installed on the bearing rod slot 335.1. The bearing rod 335 cap and the open retaining ring 336 respectively cooperate with the two mounting planes 331.4 of the pin. The above structure limits the bearing 334 in the pin groove 331.3 and allows it to rotate around the bearing rod 335. The bearing 334 rolls in contact with the upper surface of the base 100.

[0037] Specifically, such as Figures 3 to 5 As shown, the lower end of the arc-shaped guide rail limiting plate 338 has an elongated hole 338.1. The arc-shaped guide rail bearing rod 335 passes through the elongated hole 338.1 so that the rolling direction of the bearing 334 is always consistent with the sliding direction of the slide assembly 300, and the bearing rod 335 can slide up and down along the elongated hole 338.1. The upper end of the arc-shaped guide rail limiting seat 337 has a light-shielding rod 337.3, which can slide up and down within the photosensitive groove 309.1 of the photoelectric switch 339.

[0038] Specifically, such as Figures 3 to 5As shown, the arc-shaped guide rail limiting plate 338 is provided with four screw mounting holes 403.1. The arc-shaped guide rail limiting plate 338 is fixedly installed on the inner end face of the slider 310 by screws 403 through the mounting holes in the middle. The arc-shaped guide rail photoelectric switch 339 is installed on the outer end face of the limiting plate 338 by screws 403 through the mounting holes at the upper end of the limiting plate 338.

[0039] Working principle and usage process of this utility model:

[0040] In use, the slide assembly 300 slides along the guide rail 200, and the bearing 334 on the rolling plunger assembly 330 rolls on the upper surface of the base. The bearing rod 335 passes through the elongated hole 338.1 at the lower end of the limiting plate 338, so that the rolling direction of the bearing 334 is always consistent with the sliding direction of the slide assembly 300. When the slide assembly 300 reaches a specific position on the guide rail 200, the bearing 334 rolls into the limiting groove 100.1 along the chamfer 100.2 of the limiting groove of the base 100. At this time, the pin 331 is deflected by the spring 333. The light-shielding rod 337.3 at the upper end of the limit seat 337 slides down into the photosensitive groove 339.1 of the photoelectric switch 339. The bearing 334 is engaged in the limit groove 100.1 to achieve precise positioning. After the equipment on the slide assembly 300 completes its work, the slide assembly 300 continues to slide along the guide rail 200. The spring 333 is compressed, the pin 331 slides up, and the light-shielding rod 337.3 slides into the photosensitive groove 339.1 of the photoelectric switch 339. The bearing 334 rolls out of the limit groove 100.1 along the chamfer 100.2 of the limit groove of the base 100.

[0041] In summary, this utility model, through the reaction force of the spring 333 in the rolling plunger assembly 330, enables the radial relative sliding of the pin 331 and bushing 332, the limit seat 337 and photoelectric switch 339, the bearing 334 and the limiting groove 100.1 of the base 100, and the guide structure design of the bearing rod 335 and the limiting plate 338, ensures the smooth and stable use of the arc-shaped guide rail, simplifies operation, realizes instant feedback of the position of the slide, and enables precise positioning.

[0042] Although the embodiments of this utility model have been described in the specification, these embodiments are merely illustrative and should not limit the scope of protection of this utility model. Various omissions, substitutions, and modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
