Description

Technical Field

[0001] The utility model relates to the technical field of bearing processing equipment, in particular to a bearing sorting machine. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Since the use of equipment requires high dimensional accuracy of bearings, after the bearings are produced, their inner diameters need to be measured to detect whether the bearings meet the accuracy requirements and to separate bearings of different sizes of inner diameters. Existing bearing inspections mainly rely on placing a measuring instrument into the inner ring of the bearing to determine its inner diameter size and accuracy. However, in this process, the positions of the bearing and the measuring instrument remain fixed, making the position of the bearing inner diameter measured by the measuring instrument single, which is prone to measurement errors. Utility Model Content

[0003] The technical problem to be solved by the utility model is: in order to overcome the problem in the prior art that the positions of the bearing and the measuring instrument are kept fixed, so that the position of the bearing inner diameter measured by the measuring instrument is single and measurement errors are prone to occur, a bearing sorting machine is provided.

[0004] The utility model solves the technical problem by adopting the following technical solution: a bearing sorting machine, comprising a vibration plate, a frame, a conveying unit, a measuring unit, a grabbing unit and a plurality of collecting boxes for accommodating bearings installed on the frame, the vibration plate is used to arrange and output the bearings in an orderly manner, the output end of the vibration plate is connected to the input end of the conveying unit, and the conveying unit is used to sequentially convey the bearings to the measuring unit and the grabbing unit.

[0005] The measuring unit is used to measure the inner diameter of the bearing. The measuring unit includes a rotating mechanism and a measuring mechanism. The rotating mechanism is used to provide power for the rotation of the bearing. The measuring mechanism is used to detect the inner diameter of the bearing during the rotation of the bearing. The rotating mechanism includes a positioning member, a driven wheel, a driving wheel and a driving member. The positioning member is fixedly connected to the frame, the driven wheel is rotatably connected to the frame, the driving wheel is movably connected to the frame, and the driving member is transmission-connected to the driving wheel. The driving member is used to provide power for the deflection of the driving wheel and the self-rotation of the driving wheel. When the bearing moves between the driving wheel and the driven wheel, the driving wheel deflects so that the bearing presses against the positioning member and the driven wheel.

[0006] The grabbing unit is used to grab the measured bearings and transport them to the collection box corresponding to the inner diameter of the bearing. Through the design of the rotating mechanism, the bearing can rotate circumferentially during the measurement process, so that the inner diameter measuring instrument can complete the circumferential detection of the inner diameter of the bearing, ensuring the accuracy of the measured inner diameter of the bearing and the ability to detect the roundness of the bearing, so that the sorting of the assembled bearings is accurate.

The separation power piece is connected to the push rod in a transmission manner. The separation power piece is used to provide power for the movement of the push rod. The push rod is used to push a single bearing from the notch into the second transmission belt.

[0009] In order to solve the problem that the lack of obstruction in the transmission of the first conveyor belt will cause the bearing to continue to move, and the bearing will be pushed down or the equipment will be stuck when the push rod is reset, the length of the push rod is further greater than the distance between the bearing moving from the first conveyor belt to the second conveyor belt, so that the push rod blocks the movement of subsequent bearings on the first conveyor belt during the process of pushing the bearing.

The measuring power piece is fixedly connected to the frame, and the output end of the measuring power piece is transmission-connected to the inner diameter measuring instrument. The measuring power piece is used to provide power for the inner diameter measuring instrument to move into the bearing.

[0029] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0030] like Figure 1 The utility model is a structural schematic diagram of a bearing sorting machine, comprising a vibration plate 1, a frame 2, a conveying unit 3, a measuring unit 4, a grabbing unit 5 and a plurality of collecting boxes 6 for accommodating bearings installed on the frame 2. The vibration plate 1 is used to arrange and output the bearings in an orderly manner. The output end of the vibration plate 1 is connected to the input end of the conveying unit 3.

[0031] like Figure 1 , Figure 2 As shown, the conveying unit 3 is used to convey the bearings to the measuring unit 4 and the grabbing unit 5 in sequence. The conveying unit 3 includes a first conveyor belt 31, a second conveyor belt 32 and a separation mechanism 33. The output end of the vibration plate 1 is connected to the input end of the first conveyor belt 31, and the output end of the first conveyor belt 31 is connected to the input end of the second conveyor belt 32. The separation mechanism 33 is arranged at the output end of the first conveyor belt 31. The separation mechanism 33 is used to separate the bearings and allow the bearings to enter the second conveyor belt 32 alone. The measuring unit 4, the grabbing unit 5 and the collecting box 6 are arranged in sequence along the transmission direction of the second conveyor belt 32.

[0032] like Figure 1 , Figure 2 As shown, the separation mechanism 33 includes a block 331, a push rod 332 and a separation power piece 333. A notch for connecting the first transmission belt 31 and the second transmission belt 32 is provided on the side of the first transmission belt 31 close to the second transmission belt 32. The block 331 is fixedly connected to the first transmission belt 31. The block 331 is used to hinder the movement of the bearing. The separation power piece 333 is transmission-connected to the push rod 332. The separation power piece 333 is used to provide power for the movement of the push rod 332. The push rod 332 is used to push a single bearing from the notch into the second transmission belt 32.

[0033] The separation power member 333 can be a cylinder, or a power mechanism such as a slider and a slide rail structure. The separation power member 333 provides power for the reciprocating motion of the push rod 332, so that the push rod 332 can reset after pushing the bearing.

[0034] like Figure 2 As shown, the length of the push rod 332 is greater than the distance between the bearing moving from the first conveyor belt 31 to the second conveyor belt 32, so that the push rod 332 blocks the movement of subsequent bearings on the first conveyor belt 31 during the process of pushing the bearing, thereby preventing the push rod 332 from pushing down subsequent bearings when resetting or causing the bearings to occupy space so that the push rod cannot be reset.

[0035] like Figure 2 As shown, the measuring unit 4 is used to measure the inner diameter of the bearing. The measuring unit 4 includes a rotating mechanism 41 and a measuring mechanism 42. The rotating mechanism 41 is used to provide power for the rotation of the bearing. The measuring mechanism 42 is used to detect the inner diameter of the bearing during the rotation of the bearing. The rotating mechanism 41 includes a positioning member 411, a driven wheel 412, a driving wheel 413 and a driving member 414. The positioning member 411 is fixedly connected to the frame 2. The positioning member 411 can be a block, a plate structure, or a wheel structure. The positioning member 411 is used to provide a fulcrum for the bearing to prevent it from slipping during the rotation. The driven wheel 412 is rotatably connected to the frame 2, the driving wheel 413 is movably connected to the frame 2, and the driving member 414 is transmission-connected to the driving wheel 413. The driving member 414 is used to provide power for the deflection of the driving wheel 413 and the self-rotation of the driving wheel 413. When the bearing moves between the driving wheel 413 and the driven wheel 412, the driving wheel 413 deflects so that the bearing presses against the positioning member 411 and the driven wheel 412.

[0036] like Figure 4 , Figure 5 As shown, the driving member 414 includes a deflection assembly and a rotation assembly;

[0037] The deflection assembly includes a cylinder 4141, a connecting plate 4142 and a return spring 4143. The connecting plate 4142 is rotatably connected to the frame 2. The driving wheel 413 is rotatably connected to the head end of the connecting plate 4142 through an axis. The cylinder 4141 is fixedly connected to the frame 2. The piston rod of the cylinder 4141 is drivingly connected to the tail end of the connecting plate 4142. One end of the return spring 4143 abuts against the frame 2, and the other end abuts against the connecting plate 4142.

[0038] The rotating assembly includes a motor 4144, a tensioning wheel 4145 and a transmission belt 4146. The motor 4144 is fixedly connected to the frame 2, the tensioning wheel 4145 is rotatably connected to the frame 2, and the transmission belt 4146 is wound around the axis of the driving wheel 413, the tensioning wheel 4145 and the output shaft of the motor 4144 and is adjacent end to end. The motor 4144 is used to provide power for the rotation of the driving wheel 413.

[0039] like Figure 4 , Figure 5 As shown, the deflection assembly includes a mounting plate 4147 and an adjusting member 4148. The mounting plate 4147 is fixedly connected to the frame 2, the adjusting member 4148 and the mounting plate 4147 are threadedly connected, and the reset spring 4143 is arranged between the adjusting member 4148 and the connecting plate 4142. The deflection assembly can reset the driving wheel 413 on the one hand, and adjust the initial position of the driving wheel 413 on the other hand, so as to adapt to bearings with different outer diameters and increase the scope of use.

[0040] like Figure 2 As shown, the measuring mechanism 42 includes a measuring power component 421 and an inner diameter measuring instrument 422. The measuring power component 421 is fixedly connected to the frame 2. The output end of the measuring power component 421 is transmission-connected to the inner diameter measuring instrument 422. The measuring power component 421 is used to provide power for the inner diameter measuring instrument 422 to move into the bearing. The measuring power component 421 includes a transverse moving slide mechanism, a vertical moving slide mechanism, and a longitudinal moving slide mechanism, so that the inner diameter measuring instrument 422 can move in three-dimensional space so that it can be aligned with the center of the bearing.

[0041] The grabbing unit 5 is used to grab the measured bearing and transport it to the collection box 6 corresponding to the inner diameter of the bearing.

[0042] The grabbing unit 5 includes a grabbing power member 51 and a grabbing member 52. The grabbing power member 51 is fixedly connected to the frame 2. The output end of the grabbing power member 51 is transmission-connected to the grabbing member 52. The grabbing power member 51 is used to provide power for the movement of the grabbing member 52, and the grabbing member 52 is used to grab the bearing.

[0043] The grabbing power member 51 includes a transverse moving slide rail mechanism and a vertical moving slide rail mechanism. The grabbing power member 51 provides power for the grabbing member 52 to move to the collecting box 6. The grabbing member 52 can be a clamping claw cylinder.

[0044] When in use, the vibration plate 1 arranges the bearings and outputs them in order to the first conveyor belt 31, until the first bearing on the first conveyor belt 31 contacts the stopper 331, the separation power member 333 is activated to move the push rod 332, and the bearing in contact with the stopper 331 is pushed onto the second conveyor belt 32. During this process, the push rod 332 continuously blocks the movement of subsequent bearings until the push rod 332 is reset, and the subsequent bearings can continue to move until they contact the stopper 331.

[0045] After the bearing moves onto the second conveyor belt 32, the second conveyor belt 32 transports the bearing to the measuring unit 4 and is located between the driven wheel 412 and the driving wheel 413. At this time, the piston rod of the cylinder 4141 of the deflection assembly extends through the connecting plate 4142 to drive the deflection of the driving wheel 413, so that the bearing abuts against the driven wheel 412 and the positioning member 411, and then the measuring power member 421 makes the measuring end of the inner diameter measuring instrument 422 enter the inner ring of the bearing and contact the inner wall of the bearing, and the motor 4144 of the rotating assembly is started, and the driving wheel 313 is driven to rotate through the transmission belt 4146, so that the bearing rotates 180°, allowing the inner diameter measuring instrument 422 to complete the circumferential measurement of the inner diameter of the bearing;

[0046] After the measurement is completed, the piston rod of the cylinder 4141 retracts, and the driving wheel 413 is reset under the elastic force of the reset spring 4143. The second conveyor belt 32 is started, so that the bearing continues to move to the grabbing unit 5 and is grabbed by the grabbing member 52, and then moves to the top of the corresponding collection box 6, and the grip of the bearing is released to make it fall into the corresponding collection box 6.

[0047] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
