[0002] The circular guide rail conveyor line plays an important role in the handling and precise delivery of materials and products in automated production, controls the production rhythm of the entire production line, and is a core component in the automated production line. At present, the circular guide rail circulation line is basically a single-track light load, with four roller bearings meshing with the linear guide to form a circulation conveyor, which is only suitable for applications such as light loads and small carriers, and cannot be used for some high-precision circulation lines that are also required under conditions such as high loads, large carriers, and high downforce. Utility Model Content
[0003] The technical problem to be solved by the utility model is that, in view of the above-mentioned defects of the prior art, a horizontal heavy-load double-track mechanism with an annular guide rail is provided. An outer ring annular guide rail and an inner ring annular guide rail are arranged to form two closed-loop circulation tracks. A double-track heavy-load slide seat cooperates with an inner ring roller bearing and an outer ring roller bearing to form a motion assembly. The conveying load is large and the conveying accuracy is high. The mechanism is suitable for working conditions such as high load, large carrier and large downforce. The mechanism has smoother operation and a wider range of applications.
[0004] In order to solve the above technical problems, the technical solution of the utility model is:
[0005] A horizontal heavy-load double-track mechanism with an annular guide rail comprises an outer ring annular guide rail, an inner ring annular guide rail and a plurality of double-track heavy-load slide seats, wherein one side of the bottom of the double-track heavy-load slide seat is connected to the inner ring annular guide rail through an inner ring roller bearing, and the other side of the bottom of the double-track heavy-load slide seat is connected to the outer ring annular guide rail through an outer ring roller bearing.
[0006] Preferably, the inner ring roller bearing comprises an inner ring concentric roller bearing and an inner ring eccentric roller bearing, and the inner ring concentric roller bearing and the inner ring eccentric roller bearing are respectively located on the inner and outer sides of the inner ring annular guide rail.
[0007] Preferably, the outer ring roller bearing comprises an outer ring concentric roller bearing and an outer ring eccentric roller bearing, and the outer ring concentric roller bearing and the outer ring eccentric roller bearing are respectively located on the inner and outer sides of the outer ring guide rail.
[0008] Preferably, the outer ring annular guide rail comprises two outer ring linear guide rails and two outer ring circular arc guide rails, and the ends of the outer ring linear guide rails are respectively connected to the ends of the outer ring circular arc guide rails.
[0009] Preferably, the inner ring annular guide rail comprises two inner ring linear guide rails and two inner ring circular arc guide rails, and the ends of the inner ring linear guide rails are respectively connected to the ends of the inner ring circular arc guide rails.
[0010] By adopting the above technical scheme, the utility model provides a circular guide horizontal heavy-load double-track mechanism, which has the following beneficial effects: one side of the bottom of the double-track heavy-load slide in the circular guide horizontal heavy-load double-track mechanism is connected to the inner ring circular guide through an inner ring roller bearing, and the other side of the bottom of the double-track heavy-load slide is connected to the outer ring circular guide through an outer ring roller bearing.

[0015] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of the present utility model, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0016] like Figure 1 As shown, the horizontal heavy-duty double-track mechanism of the annular guide rail includes an outer ring annular guide rail 1, an inner ring annular guide rail 2 and a plurality of double-track heavy-duty slides 3. One side of the bottom of the double-track heavy-duty slide 3 is connected to the inner ring annular guide rail 2 through an inner ring roller bearing, and the other side of the bottom of the double-track heavy-duty slide 3 is connected to the outer ring annular guide rail 1 through an outer ring roller bearing. It can be understood that the outer ring annular guide rail 1 is arranged around the inner ring annular guide rail 2 and is synchronously transmitted. The outer ring annular guide rail 1, the inner ring annular guide rail 2, the plurality of double-track heavy-duty slides 3, the inner ring roller bearing and the outer ring roller bearing can all be made of stainless steel or the like.
[0017] Specifically, the inner ring roller bearing includes an inner ring concentric roller bearing 4 and an inner ring eccentric roller bearing 5, and the inner ring concentric roller bearing 4 and the inner ring eccentric roller bearing 5 are respectively located on the inner and outer sides of the inner ring annular guide 2; the outer ring roller bearing includes an outer ring concentric roller bearing 6 and an outer ring eccentric roller bearing 7, and the outer ring concentric roller bearing 6 and the outer ring eccentric roller bearing 7 are respectively located on the inner and outer sides of the outer ring annular guide 1; the outer ring annular guide 1 includes two outer ring linear guides 8 and two outer ring circular arc guides 9, and the ends of the outer ring linear guides 8 are respectively connected to the ends of the outer ring circular arc guides 9; the inner ring annular guide includes two inner ring linear guides 10 and two inner ring circular arc guides 11, and the ends of the inner ring linear guides 10 are respectively connected to the ends of the inner ring circular arc guides 11. It can be understood that the annular guide horizontal heavy-duty double-track mechanism is composed of inner and outer ring linear guides and arc guides to form a closed loop track, and a motion assembly consisting of 4 (or 6) concentric roller bearings, 8 (or 12 or more) eccentric roller bearings and a mounting plate (i.e., double-track heavy-duty slide 3). Transmission mode: chain drive or gear rack drive alone.
[0018] It is understandable that in actual application, the circular guide horizontal heavy-duty double-track mechanism consists of a closed-loop track composed of inner and outer guides and a motion component composed of multiple roller bearings. The transmission methods include chain transmission and gear rack drive alone to complete the circular circulation transmission. The technical difficulties are: 1. The horizontal accuracy of the inner and outer linear guides and the concentricity accuracy of the inner and outer arcs; 2. The debugging method of the motion component: the concentric roller bearings of the inner and outer rings are directly fixed as the installation reference of the inner and outer ring linear guides, and the debugging of the inner ring eccentric roller bearing can be directly debugged on the inner ring linear guide, among which the debugging of the outer ring eccentric roller bearing is debugged on the outer ring arc guide, and it does not touch the outer ring linear guide, in order to enable it to smoothly transform from linear motion to circular motion.
[0019] It can be understood that the utility model has a reasonable design and unique structure. It forms two closed-loop circulation tracks by setting an outer ring guide rail and an inner ring guide rail. The double-track heavy-load slide seat cooperates with the inner ring roller bearing and the outer ring roller bearing to form a moving component. Compared with the traditional annular guide conveyor line, it has a large conveying load and high conveying accuracy. A single load can achieve 100-1000kg, which can solve the problems of conveying precision differences for some products with large sizes and conveyor lines with downforce. It is suitable for working conditions such as high load, large carrier and large downforce, runs more smoothly and has a wider range of applications.
[0020] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
