[0002] Large diameter gear rings usually refer to gear rings with an outer diameter of more than 1000mm, and thin wall gear rings usually refer to gear rings with a wall thickness of less than 80mm. At present, when processing such gear rings, the conventional method is to first place the pad on the workbench of the machine tool, then place the gear ring on the pad, then install the square head long screw on the workbench, and then install the pressure plate on the square head long screw. One end of the pressure plate presses the gear ring, and the other end is supported by the support block. The overall structure is similar to a tooling fixture for gear ring processing disclosed in CN116160070A. Although the gear ring can be fixed by adopting this structure, every time the gear ring is placed, it is necessary to pay attention to the position of the bottom pad to ensure that the pad cannot be located below the tooth groove to be processed, that is, the bottom of the tooth groove needs to be suspended before processing. Due to the small thickness of the gear ring, special attention should be paid to adjusting the pad position. Every time the gear ring is replaced or the gear ring diameter changes, it is necessary to spend more time on adjusting the pad and the square head long screw, which makes the positioning of the gear ring inconvenient.

[0028] like Figure 1-4 As shown, a large diameter thin-walled hard gear ring processing base device includes a base 10, a support block 20, a clamping screw 30, a pressure plate 40 and a push rod 50. The support block 20 is installed on the base 10, and the clamping screw 30 is longitudinally installed on the support block 20. A positioning hole 41 is provided on the pressure plate 40. The pressure plate 40 is movably installed on the clamping screw 30 through the positioning hole 41. A clamping nut 31 is screwed on the clamping screw 30 at the upper side of the pressure plate 40. A limiting groove 21 is provided on one side of the upper end of the support block 20, and the other side is connected to the lower end of the push rod 50. The upper end of the push rod 50 abuts against the lower side of the pressure plate 40. The base 10 is used to be installed on a workbench, and the support block 20 is installed on the base 10. A limiting groove 21 is set on the support block 20. During production, the gear ring 60 is positioned through the limiting grooves 21 on the multiple base devices, which makes it more convenient to position the gear ring 60 during processing. After the gear ring is positioned, tighten the clamping nut 31.

[0029] In one embodiment, the top rod 50 includes a support screw 52, ​​the lower end of the support screw 52 is screwed to the support block 20, and the upper end of the support screw 52 abuts against the lower side of the pressing plate 40. When in use, the support screw 52 supports the end of the pressing plate 40 away from the gear ring 60, and the height of the support screw 52 can be adjusted by rotating, so as to adapt to gear rings of different heights.

[0030] In another implementation, see Figure 1 , 2The push rod 50 includes a push sleeve 51 and a support screw 52. The push sleeve 51 is mounted on the support block 20. The support screw 52 is screwed to the push sleeve 51. The upper end of the support screw 52 abuts against the lower side of the pressing plate 40. The support screw 52 is provided with a clamping portion 55 for twisting. When the height of the gear ring increases, the length of the support screw 52 becomes longer, which will lead to poor stability of the support screw 52. Therefore, the push rod 50 is set to a structure in which the support screw 52 is screwed to the push sleeve 51. The diameter of the push sleeve 51 is large, the structural strength is high, and the stability is good, thereby reducing the length of the support screw 52. When adjustment is required, just turn the support screw 52.

[0031] In another embodiment, see Figure 3 The support block 20 is provided with a positioning groove 24, and the lower end of the top sleeve 51 is provided with a positioning protrusion 53, which is inserted into the positioning groove 24, so as to position the top sleeve 5. In addition, when the support screw 52 is rotated, the top sleeve 5 will not rotate.

[0032] In another embodiment, a groove is provided at the position where the pressing plate 40 contacts the support screw 52, ​​and the upper end of the support screw 52 abuts against the groove, and the pressing plate 40 is limited by the support screw 52 to prevent the pressing plate 40 from rotating when the clamping nut 31 is rotated. Specifically, the groove is provided on the lower side of the pressing plate 40, and the groove is not shown in the figure.

[0033] Further, in order to adapt to the gear ring 60 of different diameters within a certain range, see Figure 2 , 3The base 10 is provided with two guide grooves 11, and an adjustment groove 12 is also provided between the two guide grooves 11 on the base 10. A guide block 22 is provided at the position corresponding to the guide groove 11 on the lower side of the support block 20, and a rotation block 23 is provided at the position corresponding to the adjustment groove 12. The guide block 22 is installed in the guide groove 11 in a sliding manner, and the rotation block 23 is located in the adjustment groove 12. An adjustment screw 13 is also provided in the adjustment groove 12, and the adjustment screw 13 is threadedly screwed with the rotation block 23. Limit plates 14 are respectively installed at both ends of the adjustment groove 12 on the base 10, and both ends of the adjustment screw 13 are respectively connected with the two limit plates 14 for rotation and limitation. One end of the adjustment screw 13 extends out of the limit plate 14 and is provided with a screwing portion 15. The adjustment screw 13 is rotated by a wrench or a hand wheel to connect with the screwing portion 15, so as to rotate the adjustment screw 13, so that the support block 20 slides along the guide groove 11. Specifically, a threaded hole is provided on the screw-joint block 23 in the direction along the guide groove 11, and the adjusting screw 13 is screwed with the threaded hole. The limit plate 14 is installed on the base 10 by bolts, and a through hole is provided on the limit plate 14 at a position corresponding to the adjusting screw 13. The adjusting screw 13 has small heads at both ends, and the small heads are inserted into the through holes. One of the small heads extends out of the limit plate 14 for a distance, and a screwing part 15 is provided on the small head extending out of the limit plate 14. The screwing part 15 is a quadrilateral or hexagonal column structure.

[0034] Specifically, the guide groove 11 is a convex groove or a dovetail groove.

[0035] When the adjusting screw 13 is rotated, the pressing screw 30 , the pressing plate 40 and the push rod 50 move along with the supporting block 20 , so that the adjustment is more convenient.

[0036] See also Figure 1 , 2 ,by Figure 1 In terms of the center position, the left side of the support block 20 is an inclined surface, which can not only ensure the installation position of the push rod 50, but also enable the support block 20 to have a larger adjustment distance.

[0037] See also Figure 3 At least two bolt holes 16 are provided on the lower side of the base 10. The bolts on the workbench are passed through the bolt holes 16 and then screwed with nuts, and the base 10 is installed on the workbench.

[0038] See also Figure 1 The pressing plate 40 is provided with a corresponding groove 42 at a position corresponding to the limiting groove 21. The corresponding groove 42 on the pressing plate 40 cooperates with the positioning groove 24 on the supporting block 20, thereby fixing the gear ring more stably.

[0039] The use process or principle of the utility model is as follows:
