Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing, in particular to a grinding machine loading device used for processing bearing rings. Background Art

[0002] The bearing ring is a part of the bearing, also known as the outer ring or outer ring. It is an annular part used to support the rolling elements of the bearing (such as balls or rollers) and fix the bearing to the external structure of the equipment or machinery. In the grinding process of the bearing ring, it is usually more appropriate to use a centerless grinder. A centerless grinder is a grinding machine specially used for processing annular parts such as bearing rings. It can provide high-precision circumferential grinding to ensure the dimensional accuracy and surface quality of the bearing ring.

[0003] When using a centerless grinder to process bearing rings, workers are required to manually place the bearing rings on the grinder feed track and manually push the bearing rings to feed them, which is time-consuming and labor-intensive. At the same time, pushing the bearing rings is dangerous. In addition, the workers' feeding efficiency is low.

[0004] Therefore, we propose a grinding machine loading device for bearing ring processing in order to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-4 As shown, the utility model provides a grinding machine feeding device for bearing ring processing, comprising: a pushing mechanism 1, which is used to intermittently push the bearing ring to the feeding port of the centerless grinder; its specific structure is as shown in Figure 2As shown, the pushing mechanism 1 includes a workbench 11, a rotating disk 12, a material guide rail plate 13, a support seat 14, a push rod 15, a push block 16, an eccentric rod 17 and a connecting rod 18. The rotating disk 12 is rotatably installed on the workbench 11, and a driving motor connected to the rotating disk 12 with a rotating shaft is arranged at the bottom of the workbench 11. A material guide rail plate 13 is arranged on one side of the top of the workbench 11. The material guide rail plate 13 is in an inverted eight-shaped structure for supporting a bearing ring. A support seat 14 is arranged between the rotating disk 12 and the material guide rail plate 13. A sliding hole is opened on the support seat 14. The push rod 15 is slidably installed in the sliding hole. A push block 16 is arranged on one end of the push rod 15 close to the material guide rail plate 13, and a connecting rod 18 is hinged on the other end of the push rod 15. An eccentric rod 17 is vertically fixed on the top of the rotating disk 12, and the end of the connecting rod 18 away from the push rod 15 is hinged to the eccentric rod 17. After falling into the guide rail 13 by the straightening mechanism 3, the driving motor drives the rotating disk 12 to rotate. When the rotating disk 12 rotates, the push rod 15 is driven to slide on the support seat 14 through the connecting rod 18, and the pushing block 16 pushes the bearing ring to move toward the feed port of the centerless grinder. When the rotating disk 12 completes one circle, the pushing block 16 completes one retraction and release of pushing materials. With the continuous rotation of the rotating disk 12, the pushing block 16 can realize intermittent pushing of the bearing ring. Compared with traditional manual pushing, it can improve safety while improving work efficiency.

[0028] The feeding mechanism 2 is located on one side of the pushing mechanism 1 and has a higher level than the pushing mechanism 1, and is used to feed the bearing ring to the pushing mechanism 1; its specific mechanism is as follows Figure 3 and Figure 4 As shown, the feeding mechanism 2 includes a U-shaped conveyor frame 21 and a conveyor belt 22. The conveyor belt 22 is installed inside the U-shaped conveyor frame 21. The top horizontal height of the U-shaped conveyor frame 21 is greater than the top height of the conveyor belt 22. A flat plate 4 is provided at one end of the side wall of the U-shaped conveyor frame 21 close to the alignment mechanism 3. The distance between the bottom of the flat plate 4 and the top of the conveyor belt 22 is greater than the width of the bearing ring and less than the double width of the bearing ring. The bearing rings are stacked in the U-shaped conveyor frame 21, and the conveyor belt 22 sends the bearing rings to the alignment mechanism 3. The setting of the flat plate 4 can ensure that the bearing rings are placed in one layer when the conveyor belt 22 is feeding, so as to prevent the bearing rings from stacking.

[0029] The straightening mechanism 3 is located between the pushing mechanism 1 and the feeding mechanism 2, and its two ends are respectively connected to the discharging end of the feeding mechanism 2 and the feeding end of the pushing mechanism 1, and is used to change the bearing ring of the pushing mechanism 1 sent by the feeding mechanism 2 to the vertical state; its specific structure is as follows Figure 2 and Figure 3As shown, the straightening mechanism 3 includes a base plate 31, a first baffle plate 32, a second baffle plate 33 and a guide plate 34. The base plate 31 is arranged in an inclined shape, one end of which is connected to the U-shaped conveyor frame 21, and the horizontal height is lower than the top height of the conveyor belt 22 to ensure that the bearing ring can fall, and the other end is connected to the guide rail 13. The width of the base plate 31 is greater than the width of the bearing ring and less than twice the width of the bearing ring, and the horizontal height of the end close to the U-shaped conveyor frame 21 is less than the top height of the conveyor belt 22 to ensure that only one bearing ring falls at a time. The first baffle plate 32 and the second baffle plate 33 are respectively installed on the front and rear sides of the base plate 31 to limit and guide the falling bearing ring to prevent it from rolling to the outside, and the end of the second baffle plate 33 close to the U-shaped conveyor frame 21 is provided with a guide plate 34 with the top inclined toward the side away from the first baffle plate 32. When the bearing ring enters the rolling groove formed by the first baffle plate 32, the second baffle plate 33 and the bottom plate 31, the bearing ring falls, and when one side of the bearing ring touches the guide plate 34, it changes to an inclined state, and the other side touches the first baffle plate 32 during the falling process, and then changes to a vertical state when continuing to fall, and finally enters the guide rail plate 13.

[0030] As a preferred technical solution of the utility model: a limit plate 5 with a downward tilted tail end is provided on one end of the side wall of the first baffle plate 32 close to the feeding mechanism 2 to prevent the conveyor belt machine 22 from rotating too fast and causing the bearing ring to fly off from the straightening mechanism 3.

[0031] As a preferred technical solution of the utility model: a baffle 6 is provided at one end of the guide rail plate 13 close to the straightening mechanism 3, and the baffle 6 is fixed to the inclined plate of the two inclined plates of the guide rail plate 13 away from the straightening mechanism 3 to prevent the bearing ring falling from the straightening mechanism 3 from flying off the guide rail plate 13.

[0032] As a preferred technical solution of the utility model: the height of the second material baffle plate 33 can be lower than the height of the first material baffle plate 32 and larger than the radius of the bearing, so that the staff can observe the unloading situation of the straightening mechanism 3.
