Description

Technical Field

[0001] The invention relates to the technical field of bearing production, and in particular to a bearing detection and unloading device. Background Art

[0002] Rolling bearings are composed of outer rings, inner rings, rolling elements and cages. The quality of each part directly determines the quality of the bearing. As a key part that directly contacts the rotating body, the bearing ring has an important impact on the installation performance, performance, quality and life of the bearing. If there are defects on the surface of the bearing ring, such as wear, cracks, bumps, pits, scratches, deformation, etc., it will cause vibration and noise in the machine, accelerate the oxidation and wear of the bearing, and even cause damage to the machine. Therefore, the surface inspection of these bearing parts is an indispensable process in the bearing production process.

[0003] At present, most of the small and medium-sized bearing manufacturers in China still mainly use manual methods to detect bearing rings. For large-scale bearing production, this manual detection method has high labor intensity, low work efficiency and high cost. Some bearing detection devices have appeared on the market to replace manual visual detection. After the bearing is detected, the bearing needs to be unloaded. The unloading of existing bearing detection devices is either done manually, which is inefficient and difficult to meet the production of large quantities of bearings; or the bearing automatic unloading mechanism is used to achieve automatic unloading, but the existing bearing automatic unloading mechanism has a single function and can only achieve simple unloading. The unloading direction is fixed and cannot meet different material collection requirements; at the same time, since the bearing needs to be positioned when it is detected, it is generally necessary to install an additional positioning device, which will complicate the structure of the detection device and increase the cost. Secondly, for bearings with different outer diameters, it is difficult to achieve positioning at the detection position. Summary of the invention

[0004] The purpose of the present invention is to provide a bearing detection and unloading device to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0005] The technical solutions adopted to solve the above technical problems are:

[0006] 1. A bearing detection and unloading device, wherein the bearing detection and unloading device has an X-axis, a Y-axis, and a Z-axis that are orthogonal to each other, and the bearing detection and unloading device comprises: a detection channel, a pushing mechanism and a stopping mechanism, the detection channel is extended along the X-axis, the detection channel has an inlet end and an outlet end that are spaced apart along the X-axis, the pushing mechanism comprises a pushing block and a pushing driving assembly, the pushing driving assembly has a pushing driving end that is transmission-connected to the pushing block and enables the pushing block to move from the inlet end to the outlet end along the detection channel; the stopping mechanism comprises a stopping rod and a stopping driving assembly, the stopping rod is arranged at the outlet end, the stopping rod is provided with a stopping end and a rotating end, the rotating end has a rotating axis extending along the Y-axis, the central axis of the stopping rod itself is perpendicular to the rotating axis, the rotating end is arranged on the bottom side of the inlet end, and the stopping driving assembly has a rotating driving end that is transmission-connected to the stopping rod and enables the stopping rod to rotate around the rotating axis.

[0007] It should be noted that the above-mentioned mutually orthogonal X-axis, Y-axis, and Z-axis are virtual features, which are set to facilitate accurate description of the relationship between various components.

[0008] The beneficial effect of the present invention is that when in use, the rotating drive end on the material stopper driving assembly drives the material stopper rod to rotate around the rotating axis, so that the material stopper end on the material stopper rod rotates to the detection channel, and the detected bearing is rolled along the detection channel from the inlet end to the outer peripheral wall of the bearing when it contacts the material stopper rod, which is the detection position of the bearing, thereby realizing the positioning of the bearing on the detection channel. Since the material stopper rod contacts tangentially with the outer circumference of the bearing, the rotation angle of the material stopper rod can be controlled according to bearings with different outer diameters to keep the bearing in the same detection position. That is, the axis of the bearing is on the same YZ coordinate plane, which is convenient for the detection device to detect the bearing; after the detection, the material blocking drive assembly drives the material blocking rod to rotate back, and makes the material blocking end on the material blocking rod rotate to the bottom of the outlet end on the detection channel, and the material blocking rod and the conveying direction of the detection channel are at a set angle, and then the push drive end on the push drive assembly drives the push block to move from the inlet end along the detection channel to the outlet end, and then the bearing can be pushed out from the outlet end by the push block, and under the guidance of the material blocking rod, the bearing can be unloaded along the set direction. Therefore, the unloading device of the present invention can realize the positioning detection of bearings with different outer diameters, as well as guided unloading, reduce the manufacturing cost of bearing detection equipment, miniaturize, and also meet different material collection needs.

[0009] As a further improvement of the above technical solution, the push drive assembly includes a pushing drive unit, a displacement drive unit, a sliding seat, and a fixed seat. The fixed seat is fixedly arranged relative to the detection channel, the pushing drive unit is arranged on the fixed seat, the pushing drive unit is provided with a pushing drive end which is transmission-connected to the sliding seat so that the sliding seat moves along the X-axis, the displacement drive unit is arranged on the sliding seat, and the displacement drive unit is provided with a displacement drive end which is transmission-connected to the push block so that the push block moves on the YZ coordinate plane.

[0010] When the bearing is inspected, the bearing rolls into the inspection channel from the inlet end on the inspection channel. In order to avoid the push block blocking the feeding of the bearing, the initial position of the push block is set beside the inlet end. When the bearing at the inspection position needs to be pushed, the displacement driving end on the displacement driving unit first drives the push block to move on the YZ coordinate plane, that is, the push block is moved to the position corresponding to the inlet end, and then the pushing driving end on the driving unit drives the sliding seat to move along the X-axis, thereby driving the push block to move from the inlet end along the inspection channel to the outlet end, and pushing the bearing at the inspection position to the outlet end; when feeding is required, the sliding seat moves back, and then the push block moves back to the side of the inlet end.

[0011] As a further improvement of the above technical solution, a guide rail extending along the X-axis is arranged on the fixed seat, and the sliding seat is slidably connected to the guide rail.

[0012] During the pushing process, the sliding seat can slide along the guide rail to improve the stability of the pushing block movement.

[0013] As a further improvement of the above technical solution, the pushing drive unit is a pushing cylinder extending along the X-axis, and the displacement drive unit is a displacement cylinder extending along the Y-axis.

[0014] The displacement cylinder and the push cylinder can increase the speed of the push block, thereby increasing the speed of bearing unloading and improving the efficiency of bearing detection.

[0015] As a further improvement of the above technical solution, the material blocking drive assembly includes a material blocking motor and a transmission shaft. The motor is fixedly arranged relative to the detection channel, the transmission shaft is transmission-connected to the material blocking motor, the transmission shaft extends along the Y-axis, and the transmission shaft is connected to the rotating end.

[0016] When the bearing needs to be blocked and positioned, the blocking motor drives the transmission shaft to rotate, and the transmission shaft drives the blocking rod to rotate around the rotation axis, so that the blocking end on the blocking rod rotates to above the plane where the detection channel is located, and rotates at a set angle according to bearings of different outer diameters; at the same time, when unloading, the blocking end on the blocking rod can also be rotated to below the plane where the detection channel is located according to the needs of collecting materials.

[0017] As a further improvement of the above technical solution, the detection channel includes a side panel and a detection platform. The side panel is extended along the X-axis. There are two side panels, and the two side panels are spaced apart along the Y-axis. The detection platform is arranged on the bottom side between the two side panels, and the material blocking rod is arranged between the two side panels.

[0018] When the bearing is being inspected, the bearing is located on the inspection table. The inspection position at this time is the inspection table. Under the guiding and limiting action of the two side plates, the bearing can be positioned in the Y-axis direction without affecting the rotation of the material blocking rod. The end of the side plate close to the outlet end extends outward, so that the bearing can also be guided and limited when the bearing is unloading.

[0019] As a further improvement of the above technical solution, the detection platform includes a fixed frame, a detection rotating shaft, and a bearing rotation drive assembly. The detection rotating shaft is extended along the Y-axis and is rotatably installed on the fixed frame. The number of the detection rotating shafts is two, and the two detection rotating shafts are spaced apart along the X-axis. The bearing rotation drive assembly is provided with a rotation drive end, which is transmission-connected to at least one of the detection rotating shafts and drives the detection rotating shaft to rotate around its own central axis.

[0020] When the bearing is inspected, the bearing is located between the two inspection rotating shafts, and the outer peripheral wall of the bearing is in conflict with the outer peripheral walls of the two inspection rotating shafts. When the rotating driving end on the bearing rotation driving assembly drives at least one inspection rotating shaft to rotate, the bearing can be driven to rotate around its own axis, and then the outer surface of the bearing can be inspected without moving the detector. For bearings with different outer diameters, their axes are all on the YZ coordinate plane in the middle between the two inspection rotating shafts. At this time, the stopper rod is in conflict with the outer peripheral wall of the bearing, which can improve the stability of the bearing between the two inspection rotating shafts, and the rotation angle of the stopper rod can be set according to the relative position of the central axis of the two inspection rotating shafts and the rotation axis of the rotating end.

[0021] As a further improvement of the above technical solution, the bearing rotation drive assembly includes a detection drive motor and a transmission structure, and the detection drive motor is transmission-connected to at least one of the detection rotation shafts via the transmission structure.

[0022] When inspecting the bearings, the inspection drive motor drives at least one of the inspection rotating shafts to rotate through the transmission structure. At the same time, the number of rotations of the inspection drive motor can be controlled according to the different outer diameters of the bearings, so that the detector can completely inspect the outer surface of the bearing.

[0023] As a further improvement of the above technical solution, the transmission structure includes a driving gear and a driven gear, at least one of the detection rotating shafts is coaxially connected to the driven gear, the output shaft of the detection drive motor is connected to the driving gear, and the driving gear is meshed with the driven gear.

[0024] The precision of detecting the rotation of the rotating shaft can be improved through the meshing transmission of the driven gear and the driving gear. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Reference Figures 1 to 4 The bearing detection and unloading device of the present invention is implemented as follows:

[0035] like Figure 1 , Figure 2 , Figure 3 As shown, the bearing detection and unloading device of this embodiment has mutually orthogonal X-axis, Y-axis, and Z-axis, and the bearing detection and unloading device includes: a detection channel 100, a pushing mechanism 200 and a blocking mechanism 300.

[0036] The detection channel 100 in this embodiment has an inlet end 110 and an outlet end 120 which are spaced apart along the X-axis. Specifically, the detection channel 100 includes a side plate 130 and a detection platform 140. The side plate 130 extends along the X-axis. There are two side plates 130. The two side plates 130 are spaced apart along the Y-axis. The detection platform 140 is arranged on the bottom side between the two side plates 130. When the bearing is detected, the bearing is located on the detection platform 140. Since the bearing is rolled and transported on the detection channel 100, the bearing can be positioned in the Y-axis direction under the guiding and limiting action of the two side plates 130.

[0037] The pushing mechanism 200 includes a pushing block 210 and a pushing drive assembly, wherein the pushing drive assembly is mainly used for moving the pushing block 210 from the inlet end 110 along the detection channel 100 to the pushing drive end of the outlet end 120, and pushing the bearing out of the outlet end 120 through the pushing block 210. Specifically, the pushing drive assembly includes a pushing drive unit, a displacement drive unit, a sliding seat 220, and a fixed seat 230. The fixed seat 230 is relatively fixedly arranged with respect to the detection channel 100. The pushing drive unit is arranged on the fixed seat 230. The pushing drive unit is provided with a pushing drive end which is transmission-connected with the sliding seat 220 so that the sliding seat 220 moves along the X-axis. The displacement drive unit is arranged on the sliding seat 220. The displacement drive unit is provided with a pushing drive end which is transmission-connected with the pushing block 210 so that the pushing block 210 moves in the YZ coordinate plane. The displacement driving end that moves upward, since the bearing rolls into the detection channel 100 from the inlet end 110 on the detection channel 100, in order to avoid the push block 210 blocking the feeding of the bearing, the initial position of the push block 210 is set beside the inlet end 110. When the bearing at the detection position needs to be pushed, the displacement driving end on the displacement driving unit first drives the push block 210 to move on the YZ coordinate plane, that is, the push block 210 is moved to the position corresponding to the inlet end 110, and then the pushing driving end on the driving unit drives the sliding seat 220 to move along the X-axis, thereby driving the push block 210 to move from the inlet end 110 along the detection channel 100 to the outlet end 120, and pushing the bearing at the detection position to the outlet end 120; when feeding is needed, the sliding seat 220 moves back, and then the push block 210 moves back to the side of the inlet end 110. The pushing drive unit in this embodiment is a pushing cylinder 240 extending along the X-axis, and the displacement drive unit is a displacement cylinder 250 extending along the Y-axis. In some other embodiments, it can be other drive units, such as electric push rods, hydraulic push rods and other linear drive units. The displacement cylinder 250 and the pushing cylinder 240 can increase the speed of the push block 210, thereby increasing the speed of bearing unloading and improving the efficiency of bearing detection.

[0038] The material stopping mechanism 300 in the present embodiment includes a material stopping rod 310 and a material stopping drive assembly, wherein the material stopping rod 310 is arranged on the outlet end 120, and one end of the side plate 130 close to the outlet end 120 extends outward, so that the material stopping rod 310 is arranged between the two side plates 130, and the material stopping rod 310 is provided with a material stopping end and a rotating end, and the rotating end has a rotating axis extending along the Y-axis, the central axis of the material stopping rod 310 itself is perpendicular to the rotating axis, and the rotating end is arranged on the bottom side of the inlet end 110; wherein the material stopping drive assembly is used to drive the material stopping rod 310 to rotate around the rotating axis, specifically, the material stopping drive assembly includes a material stopping motor 320 and a transmission shaft 330, the material stopping motor 320 is fixedly arranged relative to the detection channel 100, the transmission shaft 330 is transmission-connected to the material stopping motor 320, the transmission shaft 330 is extended along the Y-axis, and the transmission shaft 330 is connected to the rotating end.

[0039] When in use, the material stopping motor 320 drives the transmission shaft 330 to rotate, and the transmission shaft 330 drives the material stopping rod 310 to rotate around the rotation axis, so that the material stopping end on the material stopping rod 310 rotates to above the plane where the detection channel 100 is located, and the detected bearing is rolled from the inlet end 110 along the detection channel 100 to the detection platform 140, at this time, the outer peripheral wall of the bearing just happens to contact with the material stopping rod 310, thereby realizing the positioning of the bearing on the detection platform 140. Since the material stopping rod 310 is tangentially in conflict with the outer circumference of the bearing, the rotation angle of the material stopping rod 310 can be controlled according to bearings of different outer diameters, so that the bearing can be kept in the same detection position of the detection platform 140. The same detection position means that the axis of the bearing is on the same YZ coordinate plane, which is convenient for the detection device to detect the bearing; after the detection, the material stopping motor 320 drives the transmission shaft 330 to rotate back, and the material stopping end on the material stopping rod 310 is rotated to above the plane where the detection channel 100 is located, and the detected bearing is rolled from the inlet end 110 along the detection channel 100 to the detection platform 140 The material blocking end on the material rod 310 rotates to the bottom of the plane where the detection channel 100 is located, and according to the material collection requirements, the material blocking rod 310 is rotated to a set angle with the conveying direction of the detection channel 100, and then the displacement driving unit drives the pushing block 210 to move on the YZ coordinate plane, that is, the pushing block 210 is moved to a position corresponding to the inlet end 110, and then the driving unit drives the sliding seat 220 to move along the X-axis, thereby driving the pushing block 210 to move from the inlet end 110 along the detection channel 100 to the outlet end 120, and pushing the bearing on the detection table 140 to the outlet end 120, and under the guidance of the material blocking rod 310, the bearing can be unloaded along the set direction, which can realize the positioning detection of bearings with different outer diameters and guided unloading, reduce the manufacturing cost of bearing detection equipment, miniaturize it, and also meet different material collection requirements.

[0040] Furthermore, a guide rail 231 extending along the X-axis is provided on the fixed seat 230 , and the sliding seat 220 is slidably connected to the guide rail 231 . The sliding seat 220 can slide along the guide rail 231 , thereby improving the stability of the movement of the pusher block 210 .

[0041] Furthermore, the detection platform 140 includes a fixed frame 141, a detection rotating shaft 142, and a bearing rotation drive assembly. The detection rotating shaft 142 is extended along the Y axis, and the detection rotating shaft 142 is rotatably installed on the fixed frame 141. There are two detection rotating shafts 142, and the two detection rotating shafts 142 are spaced apart along the X axis. The bearing rotation drive assembly is provided with a rotation drive end, and the rotation drive end is transmission-connected with at least one of the detection rotating shafts 142, and drives the detection rotating shaft 142 to rotate around its own central axis. Specifically, the bearing rotation drive assembly includes a detection drive motor 143 and a transmission structure, and the transmission structure includes a driving gear 144 and a driven gear 145. At least one of the detection rotating shafts 142 is coaxially connected with the driven gear 145, and the output shaft of the detection drive motor 143 is connected to the driving gear 144, and the driving gear 144 is meshed with the driven gear 145. When the bearing is detected, Figure 4 As shown, the bearing is located between the two detection rotating shafts 142, and the outer peripheral wall of the bearing is in contact with the outer peripheral walls of the two detection rotating shafts 142. When the detection driving motor 143 drives the driving gear 144 to rotate, the driven gear 145 and the driving gear 144 are meshed to drive at least one detection rotating shaft 142 to rotate, thereby driving the bearing to rotate around its own axis, so that the outer surface of the bearing can be detected without moving the detector.

[0042] like Figure 4 As shown, for bearings with different outer diameters, their axes are all on the YZ coordinate plane in the middle between the two detection rotating shafts 142. At this time, the blocking rod 310 is in contact with the outer peripheral wall of the bearing, which can improve the stability of the bearing between the two detection rotating shafts 142, and the rotation angle of the blocking rod 310 can be set according to the relative position of the central axis of the two detection rotating shafts 142 and the rotation axis of the rotating end.

[0043] In some embodiments, the detection channel 100 may be a trough structure or a tubular structure, and it is sufficient to open a detection port at the position of the detection platform 140. For the transportation of the bearing, workers may place it on the detection channel 100, or a conveyor belt may be set on the detection channel 100, or the bearing may be transported and loaded by its own gravity.

[0044] In some embodiments, the push drive assembly may be other drive structures, which can enable the push block 210 to move from the inlet end 110 to the outlet end 120 along the detection channel 100 without affecting the bearing feeding. For example, it may be a swing motor, which is arranged above the detection channel 100, and the swing motor is connected to the push block 210 through a freely retractable rod. When the swing motor drives the rod to rotate, the rod can also be retracted, thereby adjusting the position between the push block 210 and the detection channel 100, and the push block 210 can be moved from the inlet end 110 to the outlet end 120 along the detection channel 100; or it may be an annular transmission belt, in which the push block 210 is arranged on the transmission belt, and the straight section on one side of the transmission belt is arranged on the outside of the detection channel 100 and parallel to the detection channel 100.

[0045] In some embodiments, the material blocking driving assembly may be a pneumatic motor, or other rotation driving structure that can drive the material blocking rod 310 to rotate around the rotation axis.

[0046] In some embodiments, the detection platform 140 may be other structures, for example, it may be a groove type. When the bearing is detected, it is necessary to control the movement of the detector; or a rotatable roller is set in the groove, and the roller is driven to rotate by an external driving mechanism, and the bearing is driven to rotate by the roller.

[0047] In some embodiments, the transmission structure may be a transmission belt and transmission wheel structure, or a cam-connecting rod transmission structure, and can drive the two detection rotating shafts 142 to rotate together.

[0048] The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
