Description

Technical Field

[0001] The utility model belongs to the technical field of bearing assembly equipment and relates to a ring structure of inner and outer rings of a bearing. Background Art

[0002] When bearings are processed, the inner ring and outer ring need to be fitted together, that is, the outer ring is fitted around the outer periphery of the inner ring. For this purpose, a specially designed fitting production line is often required.

[0003] For example, the patent with the authorization announcement number CN212349512U discloses an integrated machine for detecting and fitting inner and outer rings of bearings, comprising two conveyor lines, a conveyor plate, inner and outer ring detection devices, a fitting device and a conveyor arm, wherein the conveyor plate and the inner and outer ring detection devices are symmetrically arranged along the relative midlines of the two conveyor lines; the conveyor plate, wherein the conveyor plate is perpendicular to the inner ring conveyor line and the outer ring conveyor line and is provided with slots for receiving the inner and outer rings at intervals in sequence; the inner and outer ring detection devices, comprising an inner diameter detection component, an outer diameter detection component and a pre-fitting platform; the fitting device, comprising a fitting platform, a relatively arranged pushing component and a lifting platform; the conveyor arm, wherein the conveyor arm is arranged on a mobile platform, and the conveyor arm is directly opposite to the fitting platform and conveys the inner and outer rings on the fitting platform to the next workstation, wherein the two conveyor lines are relatively arranged, and the conveyor plate is perpendicular to the two conveyor lines.

[0004] The above device can stably achieve the fitting of the inner and outer rings of the bearing, but there are still shortcomings: when the outer ring is pushed to the fitting station, there is a groove on the surface of the station for the inner ring of the bearing to pass through, and the edge of the groove may cause scratches and damage to the outer ring of the bearing. Summary of the invention

[0005] The utility model aims at the above problems existing in the prior art and provides a ring structure of inner and outer rings of a bearing. The technical problem to be solved by the utility model is that parts are easily scratched during the prior bearing sleeve fitting process.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] The outer ring placing plate is provided with a lifting device for lifting and conveying the inner ring of the bearing, and an inner ring placing plate and an outer ring placing plate are both arranged horizontally, the inner ring placing plate is connected to a horizontally arranged inner ring push rod, and the outer ring placing plate is connected to a horizontally arranged outer ring push rod, characterized in that the upper surface of the inner ring placing plate is higher than the upper surface of the outer ring placing plate, the discharge end of the inner ring placing plate is engaged with the discharge end of the outer ring placing plate and forms a step portion, the inner ring placing plate has a vertically through-going lifting hole, the lifting device is located directly below the lifting hole, the protruding end of the inner ring push rod has a positioning column arranged downward and opposite to the lifting hole, a gap is left between the lower end of the positioning column and the upper surface of the inner ring placing plate, and the positioning column can be moved to above the discharge end of the outer ring placing plate.

[0008] The lifting device can lift the inner ring of the bearing from the bottom to the top. The inner ring placing plate and the outer ring placing plate are used for temporary placement of the inner ring and outer ring of the bearing respectively. The inner ring push rod can push the inner ring of the bearing on the inner ring placing plate to slide and push out along the upper surface. The outer ring push rod can push the outer ring of the bearing on the outer ring placing plate to slide along the upper surface. By setting the upper surface of the inner ring placing plate higher than the upper surface of the outer ring placing plate, and forming a step portion with the top higher than the outer ring of the bearing on the outer ring placing plate at the joint of the inner ring placing plate discharge end and the outer ring placing plate discharge end, a lifting hole is set on the inner ring placing plate, and the lifting device is set just below the lifting hole. A downward positioning column is set to be arranged opposite to the lifting hole, so that the outer ring of the bearing can move to the step portion to form abutment under the action of the outer ring push rod, and the inner ring of the bearing can be sent to the upper surface of the inner ring placement plate through the lifting device and the positioning column is positioned and inserted. Then the inner ring push rod can drive the inner ring of the bearing to be quickly pushed out through the step portion to above the outer ring of the bearing, so that the inner ring of the bearing falls into the outer ring of the bearing under the action of gravity. During the entire fitting process, the outer ring of the bearing is always on the outer ring conveying plate without any scratches, and the inner ring of the bearing can cross the step portion at a faster speed and reach the position without falling off due to the constraint of the positioning column, thereby greatly reducing the probability of scratches between the inner ring of the bearing and the edge of the step portion.

[0009] In the above-mentioned ring structure of the inner and outer rings of the bearing, the outer ring push rod and the inner ring push rod are arranged opposite to each other along the length direction of the outer ring push rod, and the extended end of the outer ring push rod has a vertically arranged limit plate, and the inner ring push rod is opposite to the limit plate along the length direction of the inner ring push rod. In this way, the step portion can provide more effective positioning for the outer ring of the bearing pushed out from the outer ring push rod, and at the same time, the limit plate on the outer ring push rod can limit the extension amount of the inner ring push rod in the extended state, ensuring the stability of the sleeve operation.

[0010] In the above-mentioned ring structure of the inner and outer rings of the bearing, the lower end of the positioning column is chamfered or rounded, so that when the inner ring of the bearing is lifted to the surface of the inner ring placement plate, the positioning column can be smoothly positioned and inserted into the inner ring of the bearing.

[0011] In the above-mentioned ring structure of the inner and outer rings of the bearing, the step portion is made of plastic material, which helps to avoid the rigid collision between the outer ring of the bearing and the step portion when it is pushed out, and also avoids contact scratches between the inner ring of the bearing and the edge of the step portion.

[0012] In the above-mentioned ring structure of the inner and outer rings of the bearing, the outer side of the outer ring placement plate is connected with a discharging push rod which is horizontally arranged and can reciprocate along its own length direction. The discharging push rod is perpendicular to the outer ring push rod, and the extended end of the discharging push rod has an arc-shaped notch which can match the outer ring of the bearing. In this way, the inner and outer rings of the bearing that have been fitted together can be pushed away from the fitting station by the discharging push rod, and the inner wall of the arc-shaped notch can fully fit the outer ring of the bearing to avoid damage to the outer ring of the bearing when it is pushed away.

[0013] Compared with the prior art, the advantages of the utility model are as follows:

[0014] The ring structure of the inner and outer rings of the bearing can effectively avoid scratches on the bearing components during the fitting process under the condition of stably achieving the fitting of the inner and outer rings of the bearing, thereby improving the assembly quality of the bearing.

[0024] like Figure 1 , Figure 2As shown, the ring structure of the inner and outer rings of the bearing includes a lifting device 1 for lifting and conveying the inner ring of the bearing and an inner ring placement plate 2 and an outer ring placement plate 3 both arranged horizontally, the inner ring placement plate 2 is connected to a horizontally arranged inner ring push rod 4, the outer ring placement plate 3 is connected to a horizontally arranged outer ring push rod 5, the upper surface of the inner ring placement plate 2 is higher than the upper surface of the outer ring placement plate 3, the discharge end of the inner ring placement plate 2 is connected to the discharge end of the outer ring placement plate 3 and forms a top higher than the outer ring placement plate 3, a step portion 6 is provided on the top of the outer ring of the upper bearing, a vertically penetrating lifting hole 21 is provided on the inner ring placing plate 2, the lifting device 1 is located directly below the lifting hole 21 and can deliver the inner ring of the bearing to the upper surface of the inner ring placing plate 2 through the lifting hole 21, the extended end of the inner ring push rod 4 has a positioning column 41 which is arranged downward and coaxially with the lifting hole 21, a gap is left between the lower end of the positioning column 41 and the upper surface of the inner ring placing plate 2, and the positioning column 41 can move to above the discharge end of the outer ring placing plate 3. The lifting device 1 can lift the inner ring of the bearing from the bottom to the top, and the inner ring placement plate 2 and the outer ring placement plate 3 are used for temporary placement of the inner ring and the outer ring of the bearing transported thereto, respectively. The inner ring push rod 4 can push the inner ring of the bearing on the inner ring placement plate 2 to slide and push out along the upper surface, and the outer ring push rod 5 can push the outer ring of the bearing on the outer ring placement plate 3 to slide along the upper surface. By setting the upper surface of the inner ring placement plate 2 higher than the upper surface of the outer ring placement plate 3, and forming a step portion 6 with the top higher than the outer ring of the bearing on the outer ring placement plate 3 at the junction of the discharge end of the inner ring placement plate 2 and the discharge end of the outer ring placement plate 3, and at the same time setting a lifting hole 21 on the inner ring placement plate 2, the lifting device 1 is set just below the lifting hole 21, and the inner ring push rod 4 is pressed against the lifting hole 21. The protruding end is provided with a downward positioning column 41 coaxially arranged with the lifting hole 21, so that the outer ring of the bearing can move to the step portion 6 to form abutment under the action of the outer ring push rod 5, and the inner ring of the bearing is sent to the upper surface of the inner ring placement plate 2 through the lifting device 1 and the positioning column 41 is positioned and inserted, and then the inner ring push rod 4 can drive the inner ring of the bearing to be quickly pushed out through the step portion 6 to the top of the outer ring of the bearing, so that the inner ring of the bearing falls into the outer ring of the bearing under the action of gravity. During the entire fitting process, the outer ring of the bearing is always free of scratches on the outer ring conveying plate, and the inner ring of the bearing can pass over the step portion 6 at a faster speed without being separated due to the constraint of the positioning column 41, which greatly reduces the probability of scratches between the inner ring of the bearing and the edge of the step portion 6. Preferably, the outer ring push rod 5 and the inner ring push rod 4 are arranged relative to each other along the length direction of the outer ring push rod 5, and the protruding end of the outer ring push rod 5 has a vertically arranged limit plate 51, and the inner ring push rod 4 is opposite to the limit plate 51 along the length direction of the inner ring push rod 4. In this way, the step portion 6 can provide more effective positioning for the outer ring of the bearing pushed out from the outer ring push rod 5. At the same time, the limit plate 51 on the outer ring push rod 5 can limit the extension of the inner ring push rod 4 in the extended state, ensuring the stability of the sleeve operation. The lower end of the positioning column 41 is chamfered or rounded. This is conducive to the positioning column 41 being smoothly positioned and inserted into the inner ring of the bearing when the inner ring of the bearing is lifted to the surface of the inner ring placement plate 2. The step portion 6 is a plastic material.This helps to avoid the rigid collision between the outer ring of the bearing and the step portion 6 when it is pushed out, and at the same time avoids contact scratches between the inner ring of the bearing and the edge of the step portion 6. The outer side of the outer ring placement plate 3 is connected with a horizontally arranged discharge push rod 7 that can reciprocate along its own length direction. The discharge push rod 7 is perpendicular to the outer ring push rod 5, and the extended end of the discharge push rod 7 has an arc-shaped notch 71 that can match the outer ring of the bearing. In this way, the inner and outer rings of the bearing that have been fitted can be pushed away from the fitting station by the discharge push rod 7, and the inner wall of the arc-shaped notch 71 can fully fit with the outer ring of the bearing to avoid damage to the outer ring of the bearing when it is pushed away.
