Description

Technical Field

[0001] This utility model relates to the field of edge trimming machine inspection tooling technology, and in particular to a parallelism detection device. Background Technology

[0002] Commercially produced beverages are generally filled using two-piece cans (or simply two-piece cans). A two-piece can is a metal container consisting of a lid and a seamless, one-piece can body with a bottom. The production process for the can body is as follows: the raw material is first stretched into a predetermined shape using a stretching device, and then it is trimmed by a trimming machine.

[0003] When installing the upright plate on the base of an existing trimming machine, the machine's spindle is typically used for dial indicator positioning. However, disassembling the machine's spindle is inconvenient and makes it difficult to place the magnetic dial indicator base, which in turn makes dial indicator operation inconvenient and ultimately makes the assembly of the upright plate extremely difficult. Summary of the Invention

[0007] The positioning module can be placed between the reference plate and the assembly plate on the base of the trimming machine. The positioning module has parallel positioning surfaces at both ends, and the positioning surfaces at both ends of the positioning module can respectively abut against the reference plate and the assembly plate on the base.

[0008] The detection module includes a rotating shaft and two rotating support members that are detachably connected to the reference plate and the assembly plate, respectively. The rotating shaft is rotatably connected to the reference plate and the assembly plate through the rotating support members. The outer periphery of the rotating shaft is provided with a mounting plane for placing a magnetic base.

[0009] The dial indicator probe mounted on the magnetic base placed on the mounting plane can measure the surface of the reference plate as the rotating shaft rotates.

[0010] Furthermore, the positioning module includes a positioning support plate and a pad, and both ends of the positioning support plate and the pad are provided with positioning surfaces;

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] This embodiment provides a parallelism detection device, such as... Figures 1 to 6 As shown, it includes: a positioning module and a detection module;

[0039] The positioning module can be placed between the reference plate 2 and the assembly plate 3 on the base 1 of the trimming machine. The positioning module has parallel positioning surfaces at both ends, and the positioning surfaces at both ends of the positioning module can respectively abut against the reference plate 2 and the assembly plate 3 on the base 1.

[0040] like Figure 5 As shown, the detection module includes a rotating shaft 4 and two rotating support members 9 that are detachably connected to the reference plate 2 and the assembly plate 3 respectively. The rotating shaft 4 is rotatably connected to the reference plate 2 and the assembly plate 3 through the rotating support members 9. The outer periphery of the rotating shaft 4 is provided with an installation plane 41 for placing the magnetic base 5.

[0041] The probe of the dial indicator 6 mounted on the magnetic base 5 placed on the mounting plane 41 can measure the surface of the reference plate 2 as the rotating shaft 4 rotates.

[0042] The parallelism detection device provided in this embodiment achieves parallelism positioning of the reference plate 2 and the assembly plate 3 by having the positioning surfaces at both ends of the positioning module abut against the reference plate 2 and the assembly plate 3 on the base 1, respectively.

[0043] The mounting plane 41 on the rotating shaft 4 of the detection module provides a mounting base for the magnetic dial indicator 5, which facilitates dial indicator operation. The rotating shaft 4 is rotatably connected to the reference plate 2 and the assembly plate 3 via the rotating support 9. As the rotating shaft 4 rotates, the dial indicator 6 can measure on the surface of the reference plate 2 and verify the verticality of the assembly plate 3. There is no need to disassemble the spindle of the trimming machine for dial indicator positioning, which makes the assembly of the plate more convenient.

[0044] Specifically, such as Figure 6 As shown, the positioning module includes a positioning support plate 7 and a pad 8, and both ends of the positioning support plate 7 and the pad 8 are provided with positioning surfaces;

[0045] like Figure 4 As shown, the positioning support plate 7 and the pad 8 abut against each other, and the positioning surfaces on the opposite ends of the positioning support plate 7 and the pad 8 can respectively abut against the reference plate 2 and the assembly plate 3 on the base 1.

[0046] By replacing the pads 8 with different sizes, the base 1 with different spacing between the reference plate 2 and the assembly plate 3 can be adapted, thus reducing costs.

[0047] Specifically, such as Figure 1 and Figure 2 As shown, the rotating support 9 is a flange bushing, which is connected to the reference plate 2 and the assembly plate 3 by screws.

[0048] Preferably, such as Figure 5 As shown, one end of the rotating shaft 4 is provided with a limiting protrusion 42 that cannot pass through the flange sleeve. The limiting protrusion 42 abuts against the end of the flange sleeve, thereby constraining the relative position of the rotating shaft 4 and the flange sleeve.

[0049] Preferably, such as Figure 5 As shown, the limiting protrusion 42 is provided with a handle 43. In this embodiment, the handle 43 is a bolt that is threadedly connected to the limiting protrusion 42.

[0050] Preferably, it also includes a mirror that can be placed on the base 1, through which the dial gauge reading rotated below the shaft 4 can be observed.

[0051] During actual assembly, the flange bushing is pre-installed on the reference plate 2 and the assembly plate 3. The reference plate 2 is fixed on the base 1. The positioning support plate 7 and the pad 8 are placed on the base 1. One end of the positioning support plate 7 abuts against the assembly reference surface 21, and the other end abuts against the pad 8. The end of the pad 8 away from the positioning support plate 7 abuts against the assembly plate 3, thereby achieving parallel positioning of the reference plate 2 and the assembly plate 3.

[0052] Then, the rotating shaft 4 is inserted into the flange sleeve, and the magnetic base is placed on the mounting plane 41. By rotating the rotating shaft 4 through the handle 43, the probe of the dial indicator 6 moves across the surface of the reference plate 2, and the dial indicator's marking trajectory 10 is as follows. Figure 1 As shown, the worker observes the value of dial indicator 6 to confirm whether the verticality meets the process requirements.

[0053] If it does not meet the process requirements, this assembly plate 3 shall be scrapped (if the deviation value is small, it can be returned to the machining stage for grinding).

[0054] If the process requirements are met, the base 1 and the assembly plate 3 are fixed together with screws (the assembly plate 3 has threaded holes). The worker then uses the pin holes reserved on the base 1 to ream the blind holes reserved on the assembly plate 3, so that pin holes that can be inserted into the assembly plate 3 are formed.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
