Description

Technical Field

[0001] This utility model relates to the field of concentricity detection technology, specifically a device for detecting concentric parts of electronic components that is easy to clamp. Background Technology

[0002] Bearings, used in electronic components, are mechanical elements that restrict relative motion within a desired range and reduce friction between moving parts. Bearing design can provide free linear motion or free rotation around a fixed axis for moving parts, or prevent motion by controlling the vector of the normal force acting on the moving parts. Concentricity is a crucial technical indicator for evaluating mechanical bearings; concentricity error directly affects the assembly and use of the workpiece. During production, concentricity testing equipment is needed to check the concentricity of bearings. When monitoring the concentricity of bearings, self-centering clamping is required before testing. However, self-centering clamping is typically achieved by operating two cylinders simultaneously. But the wear of the two cylinders after each use cannot be guaranteed, and after long-term use, self-centering clamping may become impossible.

[0003] For example, a mechanical bearing concentricity testing mechanism described in patent CN222124221U includes a storage box with a set of suction cup bases fixedly connected to the bottom surface of the box. The bottom surface of the storage box has a heat dissipation vent, and a rotating clamping mechanism is located above the box. This mechanism includes a housing. The bearing is placed on the housing, with two fixing blocks positioned within the inner ring of the bearing. A first hydraulic rod is then activated, moving the two fixing blocks away from each other until they are in contact with the inner wall of the bearing, thus fixing the bearing. A second hydraulic rod is then activated, moving a moving plate and a slider within a first groove until the testing head contacts the bearing. Finally, a motor is activated, rotating the shaft, which in turn rotates the housing and the bearing, thus detecting the bearing's concentricity. However, this mechanism cannot guarantee that the bearing is fixed in the center of the housing during the initial concentricity test, leading to deviations and inaccurate test results, thus reducing the device's practicality.

[0004] Based on this, a device for testing concentric parts of electronic components that is easy to clamp is provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, such as Figures 1-4 As shown, an electronic component concentric part testing device that is easy to clamp includes a base 1, a servo motor 11 fixedly connected to the bottom end of the base 1, a turntable 12 fixedly connected to the output end of the servo motor 11 through the outer wall of the base 1, a bearing 13 provided at the top of the turntable 12, a testing mechanism 2 provided inside the base 1, and a fixing mechanism 3 provided at the top of the turntable 12.

[0025] In this embodiment, the bearing 13 is self-centered and fixed by the fixing mechanism 3, so that the bearing 13 is located in the middle of the turntable 12, which facilitates the subsequent concentricity detection. Then, the concentricity of the bearing 13 can be detected by the detection mechanism 2.

[0026] In an optional embodiment, such as Figure 3 As shown, the detection mechanism 2 includes a first motor 21. The outer wall of the first motor 21 is fixedly connected to the side wall of the base 1. A first lead screw 22 is fixedly connected to the output end of the first motor 21. The outer wall of the first lead screw 22 is rotatably connected to the interior of the base 1. A first slider 23 is threadedly connected to the outer wall of the first lead screw 22. The first slider 23 is slidably connected to a groove opened inside the base 1. A mounting frame 24 is fixedly connected to the top of the first slider 23. The side wall of the mounting frame 24 is provided with linear scales parallel to the movement direction of the second slider 27. The bottom of the mounting frame 24... Guide blocks 25 are symmetrically fixedly connected at both ends. Guide blocks 25 are slidably connected to guide grooves opened on the base 1. The guide blocks 25 are T-shaped. The first motor 21 is started by the PLC, which drives the first lead screw 22 to move the first slider 23 axially, which drives the mounting frame 24 to move synchronously. The mounting frame 24 drives the guide blocks 25 to slide in the guide groove. The mounting frame 24 drives the detection head 28 to move. When the detection head 28 contacts the outer wall of the bearing 13, the PLC controls the first motor 21 to stop working, and then the detection work can begin.

[0027] In an optional embodiment, such as Figure 3 As shown, a second lead screw 26 is rotatably connected inside the mounting frame 24, and a second slider 27 is threadedly connected to the outer wall of the second lead screw 26. A pointer corresponding to the scale is provided on the side wall of the second slider 27. The outer wall of the second slider 27 is slidably connected to the groove opened on the mounting frame 24. A detection head 28 is fixedly connected to the side wall of the second slider 27. According to the thickness of the bearing 13, the second lead screw 26 is rotated to move the second slider 27 axially, thereby driving the detection head 28 to move synchronously. When the height indicated by the pointer on the side wall of the second slider 27 is half the thickness of the bearing 13, the rotation of the second lead screw 26 is stopped, which facilitates subsequent testing work.

[0028] In an optional embodiment, such as Figure 4As shown, the fixing mechanism 3 includes a second motor 31, which is fixedly connected to the inside of the turntable 12. A bidirectional lead screw 32 is fixedly connected to the output end of the second motor 31. A fixed frame 33 is rotatably connected to the outer wall of the bidirectional lead screw 32. The bottom end of the fixed frame 33 is fixedly connected to the top end of the turntable 12. A third slider 34 is symmetrically threaded onto the outer wall of the bidirectional lead screw 32. The third slider 34 is slidably connected to a groove on the fixed frame 33. Movable rods 35 are rotatably connected to all four sides of the third slider 34. A clamping plate 36 is rotatably connected to the end of the third slider 34 away from the third slider 34. The second motor 31 is started by the PLC, which drives the bidirectional lead screw 32 to rotate, so that the third slider 34 moves axially and drives the movable rod 35 to move synchronously. The movable rod 35 drives the clamping plate 36 to move, so that the clamping plate 36 moves towards the inner wall of the bearing 13. When the clamping plate 36 is in close contact with the inner wall of the bearing 13, the bearing 13 is fixed, thereby realizing the self-centering clamping of the bearing 13, which facilitates the subsequent concentricity detection.

[0029] In an optional embodiment, such as Figure 4 As shown, the clamping plate 36 has an arc shape, and a pressure sensor is provided on the working surface of the clamping plate 36. The pressure sensor monitors the squeezing force of the clamping plate 36 on the inner wall of the bearing 13 in real time. When the squeezing force reaches the preset threshold, the pressure sensor feeds back to the PLC, and then the PLC controls the second motor 31 to stop running.

[0030] In an optional embodiment, such as Figure 2 As shown, the servo motor 11, the first motor 21, the detection head 28, the second motor 31 and the pressure sensor are electrically connected through a PLC controller. The PLC can connect the various components in series to achieve precise control of each component.

[0031] The above embodiment discloses a concentric component testing device for electronic components that is easy to clamp. When concentricity testing of a bearing 13 is required, the bearing 13 is placed on a turntable 12, and a clamping plate 36 passes through the inner hole of the bearing 13. Then, a second motor 31 is started via a PLC, driving a bidirectional lead screw 32 to rotate, causing a third slider 34 to move axially, which in turn moves a movable rod 35. The movable rod 35 moves the clamping plate 36, causing it to move towards the inner wall of the bearing 13. When the clamping plate 36 contacts the inner wall of the bearing 13, a pressure sensor monitors the pressing force of the clamping plate 36 on the bearing 13 in real time. When the pressing force reaches a preset threshold, the pressure sensor sends feedback to the PLC, which then controls the second motor 31 to stop working. This achieves self-centering clamping of the bearing 13, facilitating subsequent concentricity testing. Afterwards, based on the thickness of the bearing 13, the second lead screw 26 is rotated, causing the second slider 27 to move axially, thereby driving the testing head 2. 8. Synchronous movement: When the pointer on the side wall of the second slider 27 points to half the thickness of the bearing 13, the second lead screw 26 stops rotating to facilitate subsequent testing. Then, the first motor 21 is started by the PLC, driving the first lead screw 22 to move the first slider 23 axially, which in turn moves the mounting frame 24 synchronously. The mounting frame 24 drives the guide block 25 to slide in the guide groove, and the mounting frame 24 drives the detection head 28 to move. When the detection head 28 contacts the outer wall of the bearing 13, the PLC controls the first motor 21 to stop working, and then the testing can begin. The servo motor 11 is started by the PLC to drive the turntable 12 to rotate, and the turntable 12 drives the bearing 13 to rotate synchronously. The detection head 28 detects the concentricity of the bearing 13. In summary, the bearing 13 is self-centered and fixed by the fixing mechanism 3, so that the bearing 13 is located in the middle of the turntable 12, which facilitates subsequent concentricity testing. Then, the concentricity of the bearing 13 can be tested by the detection mechanism 2.
