[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Example 1

[0023] Reference Figure 1 This embodiment discloses a bearing outer sleeve positioning mechanism for a bearing production assembly line, including a connecting frame 10, a worktable 40 below the connecting frame 10, and a power component connected to the top of the connecting frame 10. The power component is used to drive the connecting frame 10 to move vertically closer to or away from the worktable 40. A first positioning hand 20 and a second positioning hand 30 are provided opposite to each other on both sides of the connecting frame 10. The first positioning hand 20 and the second positioning hand 30 cooperate to position the bearing outer sleeve 70.

[0024] Reference Figure 1 The first positioning arm 20 includes a first connecting rod 21 and a first positioning element 22. The first connecting rod 21 is arranged vertically, and its upper part is connected to the connecting frame 10. The first positioning element 22 is disposed at the bottom of the first connecting rod 21. (Refer to...) Figure 2 The first positioning element 22 has a V-shaped positioning surface 24, and positioning blocks 23 are respectively provided on the two sides of the V-shaped positioning surface 24.

[0025] The second positioning hand 30 includes a second connecting rod 31 and a second positioning member 32 (see reference). Figure 2 The second positioning member 32 has a rod-shaped structure. The axis of the second positioning member 32 is collinear with the centerline between the V-shaped positioning surfaces 24 on both sides of the first positioning member 22. A positioning ball 33 is provided at the end of the second positioning member 32 facing the first positioning member 22. The positioning ball 33 is located on the axis of the second positioning member 32. The positioning ball 33 can be a steel ball or a ceramic ball.

[0026] Reference Figure 1 The connecting frame 10 includes a positioning base 11, which has a circular structure. A positioning groove is provided in the center of the top surface of the positioning base 11, and a positioning core 12 is provided in the positioning groove. The top of the positioning core 12 is connected to the cylinder through a connecting shaft. A positioning shaft 13 passes through the center of the positioning base 11. The upper end of the positioning shaft 13 passes through the positioning base 11 and the positioning core 12 in sequence, and its end is connected to the connecting shaft. The bottom of the positioning shaft 13 is connected to a pressure plate 14 through bolts. The pressure plate 14 and the positioning shaft 13 cooperate to clamp and fix the standard part 50 to adjust and calibrate the positions of the first positioning hand 20 and the second positioning hand 30 on both sides.

[0027] The positioning base 11 has connecting grooves on both sides. The first connecting rod 21 and the second connecting rod 31 are respectively provided with first elongated slots 61. The first connecting rod 21 and the second connecting rod 31 are respectively embedded in the connecting grooves on both sides. The bolt passes horizontally through the first elongated slot 61 and is connected to the positioning base 11, thereby fixing the first connecting rod 21 and the second connecting rod 31 to both sides of the positioning base 11. The first elongated slot 61 is used to adjust the height of the first connecting rod 21 and the second connecting rod 31 vertically.

[0028] The connecting part of the first positioning member 22 is provided with a second elongated slot 62 that runs vertically through it. The second positioning member 32 is also provided with a second elongated slot 62 that runs vertically through it. Bolts located on both sides pass through the second elongated slots 62 vertically upwards. One bolt is connected to the first connecting rod 21, and the other bolt is connected to the second connecting rod 31. The second elongated slots 62 are used to adjust the distance between the first positioning member 22 and the second positioning member 32 to accommodate bearing outer sleeves 70 of different specifications.

[0029] The working process of this embodiment:

[0030] Calibration before measurement (refer to) Figure 1 Place the standard part 50 at the bottom of the positioning shaft 13 and fix it with the pressure plate 14 and bolts. Rotate the bolt located in the second long slot 62 to adjust the position of the first positioning part 22 and the second positioning part 32 respectively, so that the positioning blocks 23 of the V-shaped positioning surfaces 24 on both sides contact the standard part 50 respectively. At the same time, make the positioning ball 33 on the second positioning part 32 contact the standard part 50. Tighten the bolt in the second long slot 62 to fix the first positioning part 22 and the second positioning part 32 respectively.

[0031] During measurement, refer to Figure 2 and Figure 3 The bearing outer sleeve 70 is placed on the worktable 40. The cylinder drives the connecting frame 10 to move vertically through the connecting shaft. The first positioning member 22 and the second positioning member 32 limit the bearing outer sleeve 70, so that the measuring probe can measure the bearing outer sleeve 70.

[0032] When the top surface of the bearing outer sleeve 70 is at a low height, exceeding the stroke range of the cylinder, the bolt located in the first long slot 61 is rotated to adjust the height of the first connecting rod 21 and the second connecting rod 31 respectively, so that the first positioning member 22 and the second positioning member 32 cooperate to measure the bearing outer sleeve 70.

[0033] Example 2

[0034] Example 2 is a further improvement on Example 1.

[0035] Reference Figure 4 Example 2 discloses an outer sleeve positioning mechanism for a bearing production assembly line. The top surface of the positioning base 11 is provided with a fine adjustment mechanism 80, which is used to synchronously adjust the height position of the first connecting rod 21 and the second connecting rod 31 on both sides.

[0036] Reference Figure 5 The fine-tuning mechanism 80 includes a threaded rod 81 and a connecting rod 85. The threaded rod 81 is perpendicular to the positioning base 11. A first gear 82 is provided at the bottom of the threaded rod 81. The first gear 82 is rotatably connected to the top surface of the positioning base 11. A baffle 83 is provided at the top of the threaded rod 81 to prevent the threaded sleeve 84 from coming off the top of the threaded rod 81. A second gear 86 is provided on the top surface of the positioning base 11 and is rotatably connected to it. The second gear 86 meshes with the first gear 82 for transmission. A handheld part 87 is provided at the top of the second gear 86.

[0037] The threaded rod 81 is fitted with a threaded sleeve 84 that is connected to its threaded transmission. The connecting rod 85 is horizontally positioned as a whole. Both ends of the connecting rod 85 are connected to the first connecting rod 21 and the second connecting rod 31, respectively. At the same time, the threaded sleeve 84 is fixedly connected to the connecting rod 85.

[0038] The working process of this embodiment follows that of Embodiment 1, and is specifically described as follows:

[0039] When the top surface of the bearing sleeve 70 is too low, causing it to exceed the cylinder stroke, rotate the bolts located in the first long slot 61 on both sides to remove the bolts from limiting the first connecting rod 21 and the second connecting rod 31. Rotate the hand-held part 87, and the first gear 82 and the second gear 86 mesh and drive each other. The threaded sleeve 84 moves vertically along the threaded rod 81, and through the connecting rod 85, it drives the first connecting rod 21 and the second connecting rod 31 on both sides to move vertically, so as to achieve the purpose of synchronously adjusting the first positioning part 22 and the second positioning part 32 on both sides, so that the height position of the first positioning part 22 and the second positioning part 32 is always consistent. After adjustment, rotate the bolts in the first long slot 61 again to fix the position of the first connecting rod 21 and the second connecting rod 32 respectively.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
