Description

Technical Field

[0001] The invention relates to the technical field of coaxiality detection, and in particular to a coaxiality detection device and a detection method for a glass conveying combined roller. Background Art

[0002] The wide glass conveyor roller has a large span, so the use of an integral roller not only requires high roller rigidity, but also has great processing difficulty. Therefore, the wide glass conveyor roller often uses a two-stage roller, and there is a certain gap between the shaft heads at both ends in the middle, and a combined roller with a coupling in the middle for transmission. In addition to certain requirements for the straightness and runout of the roller itself, this type of roller has high requirements for the coaxiality of the shaft heads on both sides when connecting the two-stage rollers, that is, it has high requirements for the radial offset and angular deviation of the two shaft heads. For the coupling, the radial offset requirement is more difficult to guarantee during assembly. When the radial offset of the two shaft heads exceeds the radial offset required by the coupling during assembly, the life of the coupling and its fastening bolts will be greatly shortened. At present, some assembly inspections for the coaxiality of two-stage rollers use a dial indicator to detect the coaxiality of the rollers at both ends. For example, China Utility Model Patent Publication No. CN214308558U discloses a coaxiality and straightness inspection tool for aluminum shaft parts, which can detect the coaxiality of shaft parts. However, the above-mentioned inspection tool is complicated to operate, has low inspection efficiency, and cannot be quickly inspected in large quantities. Some also use semi-cylindrical inspection tools, but they need to be identified by the human eye, and the inspection accuracy is poor, which is not suitable for large-scale assembly in production. Summary of the invention

[0003] The technical problem to be solved by the present invention is how to improve the detection efficiency and accuracy of the coaxiality of the combined rollers.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0005] A coaxiality detection device for a glass conveying combined roller comprises a sleeve portion and an arc portion. Both ends of the sleeve portion are provided with arc portions that can fit with the outer wall of the combined roller. The inner hole of the sleeve portion corresponds to the diameter of the combined roller shaft head.

[0006] The detection device only needs to fit the arc part on the outer wall of the shaft head of the combination roller, and then move the sleeve part left and right, so that the coaxiality of the combination roller can be quickly detected, which greatly improves the detection efficiency of the coaxiality of the combination roller, replaces human eye observation, and greatly improves the detection accuracy.

[0007] Preferably, the arc-shaped portions are symmetrically fixed at two ends of the sleeve portion.

[0008] Preferably, the arc-shaped portion is in a semicircular shape.

[0009] Preferably, the sleeve portion is also provided with a mounting hole.

[0010] Preferably, the mounting hole is a threaded hole.

[0011] Preferably, the sleeve portion and the arc-shaped portion are an integrally formed structure.

[0012] Preferably, the present invention also provides a method for taking and placing an automatic upper guard plate device for glass packaging, comprising the following steps:

[0013] Step 1: Fit the two arc-shaped parts to the outer wall of the combined roller shaft head respectively, and place the sleeve part between the two shaft heads of the combined roller;

[0014] Step 2: Move the sleeve part left and right. When both shaft heads of the combined roller can enter the inner hole of the sleeve part, the coaxiality of the combined roller meets the requirements. When one shaft head cannot enter the inner hole of the sleeve part, the coaxiality of the combined roller does not meet the requirements.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The detection device only needs to fit the arc part on the outer wall of the shaft head of the combination roller, and then move the sleeve part left and right, so that the coaxiality of the combination roller can be quickly detected, which greatly improves the detection efficiency of the coaxiality of the combination roller, replaces human eye observation, and greatly improves the detection accuracy.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0022] In this application, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means two or more, unless otherwise clearly and specifically limited.

[0023] See also Figures 1 to 3 The present embodiment discloses a coaxiality detection device for a glass conveying combination roller, comprising an integrally formed sleeve portion 1 and an arc portion 2. The sleeve portion 1 has arc portions 2 symmetrically arranged at both ends thereof, which can fit with the outer wall of the combination roller 3. In the present embodiment, the arc portion 2 is semicircular in shape. The inner hole of the sleeve portion 1 corresponds to the diameter of the shaft head of the combination roller 3. Specifically, the inner hole diameter of the sleeve portion 1 is determined according to the shaft head diameter of the combination roller 3 and the maximum radial deviation allowed by the combination roller 3. Once the shaft head of the combination roller 3 can be smoothly slid into the inner hole of the sleeve portion 1, it can be ensured that the coaxiality tolerance of the two shaft heads will be less than the limit tolerance requirement of the coaxiality of the combination roller 3, thereby ensuring that the coaxiality requirement of the combination roller 3 is met during installation.

[0024] The detection device only needs to fit the arc portion 2 on the outer wall of the shaft head of the combination roller 3, and then move the sleeve portion 1 left and right, so that the coaxiality of the combination roller 3 can be quickly detected, which greatly improves the coaxiality detection efficiency of the combination roller 3, replaces human eye observation, and greatly improves the detection accuracy.

[0025] Furthermore, the sleeve portion 1 is provided with a mounting hole 11 for mounting a handle to facilitate movement of the sleeve portion 1. In this embodiment, the mounting hole 11 is a threaded hole.

[0026] The present invention also provides a method for detecting the coaxiality of a glass conveying combined roller, comprising the following steps:

[0027] Step 1: The two arc-shaped parts 2 are respectively attached to the outer walls of the shaft heads of the combined roller 3, and the sleeve part 1 is placed between the two shaft heads of the combined roller 3;

[0028] Step 2: Move the sleeve part 1 left and right. When the two shaft heads of the combined roller 3 can enter the inner hole of the sleeve part 1, the coaxiality of the combined roller 3 meets the requirements. When one shaft head cannot enter the inner hole of the sleeve part 1, the coaxiality of the combined roller 3 does not meet the requirements.

[0029] This method can quickly detect the coaxiality of the combined roller 3 by only moving the sleeve part 1 left and right, which greatly improves the coaxiality detection efficiency of the combined roller 3 and replaces human eye observation, and the detection accuracy is also greatly improved.
