DETAILED DESCRIPTION
[0035] The following is combined with Figure 2-5 This application is described in further detail.
[0036] The present application embodiment discloses a cycloidal sheet boring tool. Figure 2 The cycloid piece boring tool comprises a base 1, on which at least three positioning disks 2 are arranged along the vertical direction, and the cycloid piece 101 is clamped between two adjacent positioning disks 2; it should be noted that, since it is necessary to simultaneously process the two cycloid pieces 101 used on the same cycloid reducer, the cycloid pieces 101 clamped by the cycloid piece boring tool are an even number, that is, the number of the positioning disks 2 placed is the cardinal number. In this embodiment, three positioning disks 2 are set as an example, that is, two cycloid pieces 101 can be bored simultaneously each time.
[0037] Reference Figure 3 and Figure 4 In this embodiment, a first positioning member 3 for limiting the rotation of the positioning disk 2 is provided on the base 1, and a second positioning member 4 for limiting the rotation of the cycloid plate 101 relative to the positioning disk 2 is provided on the side wall of all positioning disks 2 facing the cycloid plate 101. The cycloid plate 101 can be positioned on the base 1 through the first positioning member 3 and the second positioning member 4, and the center holes 102 of the two cycloid plates 101 are connected after positioning, so that the boring equipment can be inserted into the center holes 102 of the two cycloid plates 101, and the side walls of the center holes 102 are polished for the second time, thereby further improving the concentricity of the positioning holes 103 on the two cycloid plates 101.
[0038] Refer to 3 and Figure 4Specifically, the first positioning member 3 may be a first positioning column 31 disposed on the base 1, and the positioning column may be a rectangular structure. A first positioning hole 103 for the first positioning column 31 to be inserted and connected is correspondingly provided on the positioning disk 2 at the bottom, so that the positioning disk 2 can be initially positioned by the cooperation between the first positioning column 31 and the first positioning hole 103; further, a plurality of first positioning columns 31 may be provided circumferentially, and the first positioning holes 103 and the first positioning columns 31 are provided one by one, so that the positioning accuracy of the positioning disk 2 can be improved. Optionally, the first positioning column 31 may pass through the first positioning hole 103 and be inserted into the special-shaped hole of the cycloid plate 101, so as to position the positioning disk 2 at the bottom.
[0039] Reference Figure 3 and Figure 4 In this embodiment, the second positioning member 4 is a second positioning column 41. At least two second positioning columns 41 are arranged on the side wall of all positioning disks 2 facing the cycloid plate 101. The second positioning columns 41 can be fixed to the positioning disk 2 by means of threaded connection or the like. The second positioning columns 41 are circular columns, and all second positioning columns 41 located on the same side of the positioning disk 2 can be inserted into the special-shaped holes of adjacent cycloid plates 101, and preferably abut against the side wall of the special-shaped hole 104, so as to limit the rotation of the cycloid plate 101 relative to the positioning disk 2. Furthermore, a clearance groove 42 can be provided on the end surface of the second positioning column 41 away from the positioning disk 2, so that two mutually symmetrical semicircular blocks are formed at the end of the second positioning column 41. When the side wall of the second positioning column 41 is pressed, the semicircular block can be deformed toward the clearance groove 42, so as to facilitate the insertion of the second positioning column 41 into the special-shaped hole 104. It should be noted that, since the second positioning posts 41 between two adjacent positioning disks 2 are inserted into the same positioning disk 2 , the second positioning posts 41 on the two positioning disks 2 need to be staggered during design.
[0040] Reference Figure 3 and Figure 4 In an optional embodiment, the locking bolt 5 on the uppermost positioning plate 2, the stud portion of the locking bolt 5 can be sequentially passed through the positioning plates 2 and the cycloid pieces 101 downwards, and threadedly connected with the positioning plate 2 at the lowermost position, so that all the positioning plates 2 and the cycloid pieces 101 are mutually locked, further restricting the two cycloid pieces 101 from rotating relative to each other, thereby further improving the stability of the entire tooling. Among them, multiple locking bolts 5 can be provided, and the corresponding positioning plates 2 are provided with openings for the screw portion of the locking bolt 5 to pass through, and the locking bolt 5 can pass through the special-shaped hole 104 of the cycloid piece 101.
[0041] Reference Figure 2 and Figure 3In an optional embodiment, a positioning seat 6 can also be provided on the base 1, and a limiting block 61 is provided on the side wall of the positioning seat 6 facing the cycloid piece 101, and the limiting block 61 can mesh with the external teeth on the side wall of the cycloid piece 101; this design can further facilitate the positioning of the cycloid piece 101, and can also prevent the cycloid piece 101 from rotating or shifting during the processing, thereby ensuring the accuracy of the processing. The upper surface of the limiting block 61 can be provided with an arc-shaped chamfer, so that when the cable tray is taken up and down, the friction resistance between the limiting block 61 and the cycloid piece 101 can be reduced, making the installation and removal of the cycloid piece 101 smoother.
[0042] Reference Figure 2 and Figure 5 Furthermore, the positioning seat 6 can be adjustably fixed on the base 1 to adjust the position of the limit block 61, and the base 1 can be provided with a groove for clamping and placing the positioning seat 6, so as to improve the stability of the positioning seat 6 during installation. Specifically, the positioning seat 6 is also provided with a positioning bolt 62, and the positioning seat 6 is provided with a waist-shaped groove, which extends in the direction toward the center of the cycloid piece 101. The positioning bolt 62 can pass through the waist-shaped groove and be threadedly connected with the base 1; by adjusting the position of the positioning seat 6, the distance between the limit block 61 and the cycloid piece 101 can be adjusted, so as to ensure that the limit block 61 can abut against the side wall of the outer teeth of the cycloid piece 101.
[0043] Reference Figure 3 and Figure 4 In an optional embodiment, a support block 7 may be further provided on the base 1. The support block 7 has a circular cross-section and is detachably fixed to the base 1 by bolts or the like. A center column 71 is coaxially fixed to the support block 7. The center column 71 can coaxially pass through all the positioning disks 2 and the cycloid pieces 101. The center column 71 is matched with the center hole 102 provided on the cycloid pieces 101, and the first positioning column 31 is fixed to the upper surface of the support block 7. Thus, through the center column 71, it can be ensured that all the positioning disks 2 and the cycloid pieces 101 are arranged around the same center axis 711, thereby improving the coaxiality and machining accuracy of the entire tooling.
[0044] Reference Figure 4Furthermore, the center column 71 can be composed of a center shaft 711 and a sleeve 712. An oil storage chamber 72 is arranged between the center shaft 711 and the sleeve 712, and the oil storage chamber 72 is an annular cavity; at the same time, a guide groove 73 is also opened on the center shaft 711, and an adjusting screw 74 is threadedly connected to the side wall of the support block 7, and an adjusting hole 75 is opened for the adjusting screw 74 to be threadedly connected. The oil storage chamber 72, the guide groove 73 and the adjustment hole 75 are all interconnected, and a closed space is formed under the cooperation of the sleeve 712, the support block 7 and the adjusting screw 74, and oil is stored in the closed space; by rotating the adjusting screw 74 and changing the depth of the adjusting screw 74, the oil pressure in the oil storage chamber 72 can be adjusted; when the adjusting screw 74 is rotated and screwed in, the oil pressure increases, and the sleeve 712 expands outward, so that it can be clamped on the inner side wall of the positioning plate 2 and the cycloid plate 101 on the center column 71, thereby further increasing the stability of fixing the positioning plate 2 and the cycloid plate 101.
[0045] The implementation principle of a cycloidal piece boring tool in the embodiment of the present application is as follows: the cycloidal piece 101 is clamped by multiple positioning disks 2 on the base 1, and the first positioning member 3 and the second positioning member 4 are used to restrict the rotation of the positioning disk 2 and the cycloidal piece 101 respectively, thereby achieving high-precision positioning of the cycloidal piece 101; and the two cycloidal pieces 101 can be fixed at the required positioning position at the same time, so that the boring equipment can perform secondary processing and boring on the side walls of the positioning holes 103 of the two cycloidal pieces 101; at the same time, by adding structures such as locking bolts 5, limit blocks 61 and center columns 71, the positioning accuracy, structural stability and ease of use of the cycloidal piece boring tool are further improved.
[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
