Description

Technical Field

[0001] This utility model relates to the technical field of bearing ring testing devices, and in particular to a bearing ring testing device for a heat treatment production line. Background Technology

[0002] Bearings are a crucial component in various mechanical equipment, and their precision plays a decisive role in the equipment's accuracy, performance, and lifespan. Bearing races are a major part of the bearing, and their size determines the bearing's performance. Therefore, after heat treatment, the bearing races often need to be inspected for their size and specifications using testing equipment.

[0003] Currently, bearing ring inspection devices require manual placement of the bearing rings onto the device for testing. This becomes time-consuming and labor-intensive when inspecting a large number of bearing rings, and lacks continuous and automated inspection capabilities, resulting in low efficiency. Therefore, this invention proposes a bearing ring inspection device for a heat treatment production line to address these problems. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the background art by proposing a bearing ring testing device for a heat treatment production line.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bearing ring testing device for a heat treatment production line, comprising:

[0007] Base;

[0008] A U-shaped plate is fixedly installed on the top of the base, and a fixing plate is fixedly installed on the open side of the U-shaped plate, and the fixing plate is fixedly installed on the top of the base;

[0009] The detection assembly includes a laser rangefinder fixedly mounted on the top of a fixed plate. The measuring end of the laser rangefinder is provided with a detection plate. A magnetic block is fixedly mounted on the other side of the detection plate. An electromagnet is provided on the other side of the magnetic block and is fixedly mounted on the top of a U-shaped plate. A spring is connected between the side of the detection plate near the magnetic block and the inner side of the U-shaped plate. Guide plates are fixedly mounted on both sides of the detection plate. Guide rods slide through the surfaces of both guide plates and are horizontally fixed inside the U-shaped plate.

[0010] The conveying assembly includes two conveying rollers that are movably mounted on both sides of a U-shaped plate. One of the conveying rollers has a common portal shaft running through both ends, and the two ends of the portal shaft are fixedly mounted on the surfaces of the U-shaped plate and the fixed plate, respectively. A conveyor belt is drivingly connected between the portal shaft and the conveying roller. A fixed shell is movably fitted on the surface of the other conveying roller, and the fixed shell is fixedly mounted on the surface of the fixed plate.

[0011] An intermittent drive assembly is installed inside the fixed housing and is used to control the intermittent rotation of the corresponding conveyor rollers.

[0012] Preferably, the intermittent drive assembly includes a gear fixedly mounted on the surface of one of the conveying rollers, and the gear is placed inside a fixed housing. An incomplete gear is externally engaged or disengaged from the gear, and the incomplete gear rotates within the fixed housing. A drive motor for driving the incomplete gear to rotate is fixedly mounted on the outer side of the fixed housing. A touch switch is provided on the side of the incomplete gear away from the gear, and the touch switch is fixedly mounted inside the fixed housing. An arc-shaped block is fixedly mounted on the toothed part of the incomplete gear, and the arc-shaped block contacts or separates from the touch switch.

[0013] Preferably, the electromagnet and the switch are electrically connected.

[0014] Preferably, the measuring end of the laser rangefinder, the inner surface of the fixed plate, and the side of the conveyor belt near the fixed plate are all on the same plane.

[0015] Preferably, the bottom of the detection plate and the upper surface of the conveyor belt are on the same plane.

[0016] Preferably, the conveyor belt extends through both sides of the U-shaped plate, and two through holes are provided on both sides of the U-shaped plate, with the through holes being movably connected to the conveyor belt.

[0017] Compared with existing technologies, the advantages of the bearing ring testing device for a heat treatment production line provided by this utility model are as follows:

[0018] This invention uses a drive motor to control the intermittent meshing of incomplete gears and gears, enabling automatic start and stop when conveying multiple bearing rings to be tested. This allows the detection plate to move away from the bearing rings as they move, and conversely, when the bearing rings stop, a touch switch is activated, energizing the electromagnet to repel the magnetic block, causing the detection plate to contact the bearing rings. Under the measurement of a laser rangefinder, this achieves automatic and continuous testing of multiple bearing rings, improving the efficiency of bearing ring testing. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1 to 3 A bearing ring testing device for a heat treatment production line, comprising:

[0025] A base 1 and a U-shaped plate 2 are fixedly installed on the top of the base 1. A fixing plate 3 is fixedly installed on the open side of the U-shaped plate 2, and the fixing plate 3 is also fixedly installed on the top of the base 1. A detection component includes a laser rangefinder 4 fixedly installed on the top of the fixing plate 3. The laser rangefinder 4 is electrically connected to an external computer via a data cable. The external computer is used to display the data measured by the laser rangefinder 4. This part is existing publicly available technology and will not be described in detail in this technical solution.

[0026] The measuring end of the laser rangefinder 4 is equipped with a detection plate 8. The end of the laser rangefinder 4, the inner surface of the fixed plate 3, and the side of the conveyor belt 12 near the fixed plate 3 are all on the same plane, so that the distance from the measuring end of the laser rangefinder 4 to the detection plate 8 is the outer diameter of the bearing ring being detected.

[0027] A magnetic block 11 is fixedly installed on the other side of the detection plate 8. An electromagnet 10 is provided on the other side of the magnetic block 11, and the electromagnet 10 is fixedly installed on the top of the U-shaped plate 2. A spring 9 is connected between the side of the detection plate 8 near the magnetic block 11 and the inner side of the U-shaped plate 2. Guide plates 7 are fixedly installed on both sides of the detection plate 8. Guide rods 6 slide through the surfaces of both guide plates 7, and the guide rods 6 are horizontally fixed inside the U-shaped plate 2. When the electromagnet 10 is energized, it can repel the magnetic block 11 to push the detection plate 8 to move and stretch the spring 9. When the power is off, the spring 9 can pull the detection plate 8 back to reset.

[0028] The conveying assembly includes two conveying rollers 15 that are movably mounted on both sides of the U-shaped plate 2. One of the conveying rollers 15 has a gantry shaft 16 passing through both ends. The two ends of the gantry shaft 16 are fixedly mounted on the surfaces of the U-shaped plate 2 and the fixed plate 3, respectively. A conveyor belt 12 is connected between the gantry shaft 16 and the conveying roller 15. The conveyor belt 12 movably passes through both sides of the U-shaped plate 2. Two through holes are opened on both sides of the U-shaped plate 2, and the through holes are movably connected to the conveyor belt 12. The conveyor belt 12 can automatically convey the bearing rings to be tested.

[0029] Another conveyor roller 15 is movably fitted with a fixed shell 13, and the fixed shell 13 is fixedly installed on the surface of the fixed plate 3. The upper surface of the conveyor belt 12 and the bottom of the detection plate 8 are on the same plane to prevent the bearing ring to be detected from being too small, so that the detection plate 8 cannot contact the bearing ring and thus cannot detect it.

[0030] An intermittent drive assembly is installed inside a fixed housing 13 and is used to control the intermittent rotation of a corresponding conveyor roller 15. The intermittent drive assembly includes a gear 17 fixedly installed on the surface of one of the conveyor rollers 15, and the gear 17 is placed inside the fixed housing 13. An incomplete gear 18 is engaged or disengaged from the gear 17, and the incomplete gear 18 rotates inside the fixed housing 13. A drive motor 14 for driving the rotation of the incomplete gear 18 is fixedly installed on the outside of the fixed housing 13. A touch switch 18 is provided on the side of the incomplete gear 18 away from the gear 17, and the touch switch 18 is fixedly installed inside the fixed housing 13. An arc-shaped block 19 is fixedly installed on the toothed part of the incomplete gear 18, and the arc-shaped block 19 contacts or separates from the touch switch 5. The touch switch 5 and the electromagnet 10 are electrically connected. When the arc-shaped block 19 contacts the touch switch 5, the electromagnet 10 is energized; otherwise, the electromagnet 10 is de-energized.

[0031] The working principle of this utility model is as follows:

[0032] In use, first place the heat-treated bearing ring on the conveyor belt 12 and start the drive motor 14 to drive the incomplete gear 18 to rotate. When the incomplete gear 18 and gear 17 mesh, it can drive gear 17 to rotate, thereby driving the conveyor roller 15 to rotate. At this time, the conveyor belt 12 starts to move and stops rotating. At this time, the bearing ring to be tested stops at the position corresponding to the detection plate 8. At the same time;

[0033] Then, when the incomplete gear 18 rotates to the toothless part and the gear 17 is not meshed, the arc block 19 on the incomplete gear 18 contacts the touch switch 5. At this time, the electromagnet 10 is energized to repel the magnetic block 11 and push the detection plate 8 toward the bearing ring to be detected on the conveyor belt 12 until it contacts it and presses it against the inner wall of the U-shaped plate 2.

[0034] Finally, the laser rangefinder 4 measures the distance to the detection plate 8, thus obtaining the size of the bearing ring. At this point, under the intermittent meshing of the incomplete gear 18 and gear 17 controlled by the drive motor 14, the effect of automatically detecting the outer diameter of multiple bearing rings can be achieved.

[0035] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
