Description

Technical Field

[0001] The utility model relates to the technical field of a material discharge platform of a press-fitting machine, in particular to a rotary switching press-fitting mechanism. Background Art

[0002] Pressing refers to a device that presses parts into the corresponding equipment through pressure. It is generally used in the production of bearings or motors. The bearing is placed under the press, and then the corresponding built-in components are placed in the middle of the bearing. Finally, the built-in components are pressed into the bearing through hydraulic and other pressing methods. In order to improve efficiency, a rotating discharge platform is generally set up. Automatic bearing replacement through rotation is also one of the common production methods now.

[0004] According to the "a rotary switching press-fitting mechanism" with the publication number "CN220560850U", it is mainly provided with an electric cylinder mounting seat, a turntable mounting seat, a turntable, a pressure rod mounting plate, a rotating shaft and a bearing seat. The bearing seat is installed in the turntable mounting seat, and the bearing seat is driven by the rotating shaft to rotate, and then the turntable on one side of the turntable mounting seat is driven to rotate, so as to achieve the purpose of selecting the pressure rod mounting plate on the turntable. Compared with the traditional steel ball press-fitting assembly, it is much more convenient and has higher installation accuracy, which improves production efficiency and reduces production costs.

[0005] Because the built-in parts need to be pressed into the bearing, a lot of pressure is required, and this pressure will also act on the rotating platform. The current rotating platform does not have a good way to deal with this, so long-term use will cause the rotating platform to bend and become uneven. These problems will also directly affect the pressing effect. For this reason, a rotating switching pressing mechanism is established. Utility Model Content

DETAILED DESCRIPTION

[0016] The utility model will be further described below in conjunction with the accompanying drawings.

[0017] Please refer to Figure 1-3 The utility model discloses a rotary switching press-fitting mechanism, comprising a fixed platform 1, a rotating platform 4 is set above the fixed platform 1, a buffer pad 5 is evenly fixedly connected to the rotating platform 4 away from the fixed platform 1 and close to the edge, and the buffer pad 5 is a cylindrical rubber pad. Four springs 11 are set on the top of the rotating platform 4 and close to the side wall of the buffer pad 5. The top of the spring 11 is away from the rotating platform 4 and is fixedly connected to a connecting plate 7. A docking column 6 is fixedly connected in the middle of the side wall opposite to the connecting plate 7 and the buffer pad 5. The side wall opposite to the fixed platform 1 and the rotating platform 4 is evenly fixedly connected to an auxiliary support column 2;

[0018] A limit rod 15 is sleeved and connected inside the spring 11, and the limit rod 15 is a retractable structure. The limit rod 15 and the spring 11 are fixedly connected to the bottom side wall of the connecting plate 7 through the top end. The end of the limit rod 15 away from the connecting plate 7 is fixedly connected to the mounting seat 12, and the mounting seat 12 is fixedly connected to the bottom end of the spring 11. A rotating groove is opened in the middle of the top side wall of the auxiliary support column 2, and a rotating ball 3 is rotatably connected in the rotating groove, and the rotating ball 3 is in close contact with the bottom side wall of the rotating platform 4.

[0019] The technical effect of this solution is that the built-in components are pressed by hydraulic pressure. At this time, the downward pressure will drive the storage rack 8 and the connecting plate 7 to descend synchronously. As the connecting plate 7 descends, the spring 11 and the limit rod 15 are contracted to relieve the impact of the pressure on the rotating platform 4. As the cushion pad 5 descends, it will contact the docking column 6. Because the cushion pad 5 is a rubber pad, it will also contract to relieve the pressure. When the cushion pad 5 contacts the docking column 6, the built-in components will be pressed into the bearing under the action of pressure to complete the press-fitting process. As the hydraulic pressure rises, the connecting plate 7 and the storage rack 8 will also rise synchronously driven by the spring 11 and the limit rod 15.

[0020] An inner groove is provided in the middle of the side walls opposite to the fixed platform 1 and the rotating platform 4, and a motor 13 is detachably embedded and connected inside the inner groove, an expansion plate 14 is fixedly connected to the output end of the motor 13, and the expansion plate 14 is a conical structure. The rotating platform 4 is detachably connected to the expansion plate 14 through the bottom side wall, and the top plane of the expansion plate 14 is at the same level as the highest point of the rotating ball 3. A storage rack 8 is fixedly connected in the middle of the side wall of the connecting plate 7 away from the docking column 6, and the storage rack 8 is a cylindrical structure. A placement groove 9 is provided in the middle of one end of the storage rack 8 away from the connecting plate 7, and a retractable sleeve rod 10 is fixedly connected in the middle of the bottom side wall in the placement groove 9, and a bearing sleeved on the sleeve rod 10 is placed in the placement groove 9.

[0021] The technical effect of this solution is that auxiliary support columns 2 are fixedly connected to the top side walls of the fixed platform 1, and the number and positions of the auxiliary support columns 2 are aligned with the buffer pads 5. When the rotating platform 4 rotates to rotate the storage rack 8 with the new bearing under the hydraulic press, the auxiliary support columns 2 and the rotating balls 3 are aligned below for support. During the pressing process, thanks to the support of the auxiliary support columns 2 and the rotating balls 3, it can be ensured that the rotating platform 4 will not tilt toward the force-bearing surface and always maintain a horizontal and stable state, thereby preventing the rotating platform 4 from tilting or even bending due to force, and also avoiding the defective products caused by it.

[0022] Specifically, when the utility model is used, the motor 13 is started to drive the rotating platform 4 to rotate, and the rack 8 is rotated and adjusted, so that the bearing is replaced and pressed. In order to ensure the stability between the motor 13 and the rotating platform 4, an expansion plate 14 is fixedly connected to the output end of the motor 13. The expansion plate 14 can increase the contact area between the rotating platform 4 and the output end of the motor 13. Because the expansion plate 14 is a conical structure, the stability of the rotating platform 4 itself can be greatly improved. In conjunction with the auxiliary support column 2 and the rotating ball 3, the rotating platform 4 can also maintain considerable stability during the processing process. In order to ensure the smooth rotation of the rotating platform 4, the rotating ball 3 is set in a rotating state, which can reduce the influence of friction on the rotation of the rotating platform 4. The four springs 11 and the limit rods 15 can shrink during the press-fitting process, alleviate the influence of pressure on the rotating platform 4, and improve the service life of the rotating platform 4. Because each connecting plate 7 is connected to the four limit rods 15, the four limit rods 15 can stably support the connecting plate 7, ensure the stability of the connecting plate 7 and the storage rack 8 themselves, and avoid the connecting plate 7 and the storage rack 8 themselves from tilting during the processing process, affecting production.

It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
