Description

Technical Field

[0001] This invention relates to the field of laser measurement technology, and more specifically, to a laser measurement device for detecting motor parts. Background Technology

[0002] In the field of motor manufacturing, the motor shaft is a core transmission component, and its diameter accuracy directly affects the assembly accuracy and operational stability of the motor. Therefore, strict dimensional inspection of the motor shaft is necessary. Currently, laser measurement of motor shafts mostly adopts semi-automatic or manual-assisted methods, which have the following technical defects:

[0003] 1. Low feeding efficiency: Traditional devices require manual placement of motor shafts at the measuring station one by one, or feeding through a simple vibratory feeder. However, the vibratory feeder can easily cause the motor shaft to deviate, requiring additional manual adjustment, making it difficult to achieve continuous and stable feeding, which limits the efficiency of batch testing.

[0004] 2. Poor coordination between measurement and feeding: After the measurement is completed, the feeding action of the motor shaft is often disconnected from the measurement process. The feeding mechanism needs to be controlled separately, which can easily lead to problems such as "missed feeding" or "repeated measurement", affecting the continuity of the test.

[0005] 3. Insufficient reliability of limit switches: Precise positioning of the motor shaft is required during measurement. Currently, most limit switch structures use rigid clamping or single-direction limit switches, which are prone to measurement errors due to slight vibrations of the motor shaft. Furthermore, the linkage between limit switch release and unloading action is poor, further reducing efficiency.

[0006] Therefore, there is an urgent need for a laser measurement device based on the inspection of motor parts to solve the problems of low efficiency, poor coordination, and insufficient reliability in the existing technology. Summary of the Invention

[0007] To overcome the shortcomings of the prior art, the present invention provides a laser measurement device for the detection of motor parts.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a laser measuring device for detecting motor parts, comprising: a base;

[0009] The feeding assembly includes a housing and a rotating drum located inside the housing. A conical disk is fixed to the end of the rotating drum, and a toothed plate is fixed to the inclined surface of the conical disk. A guide plate communicating with the bottom of the housing is fixed to the bottom of the housing.

[0010] A load-bearing component, including a load-bearing ring;

[0011] A rotating assembly includes a rotating ring, the inner wall of which has a track groove for accommodating a bearing ring. A toothed ring and a conical ring are fixedly sleeved on the circumference of the rotating ring. A toothed plate is fixed on the circumference of the conical ring to drive a toothed plate to rotate to the next position. Two symmetrically distributed laser measuring instruments are fixed on the rotating ring. A fixed ring with the same central axis as the rotating ring is also fixed on the rotating ring. An arc-shaped plate is fixedly sleeved on the circumference of the fixed ring.

[0012] A limiting assembly includes an inclined plate with a cross-shaped slider that blocks the motor shaft sliding on the inclined plate. A connecting post is fixed on the cross-shaped slider, and the side of the connecting post away from the cross-shaped slider is attached to the outside of the fixed ring.

[0013] in:

[0014] The drive gear ring and gear plate 2 rotate. The rotation of the gear ring drives the arc plate to rotate. The arc plate squeezes the connecting column until the cross-shaped slider no longer blocks one end of the motor shaft. At the same time, each rotation of gear plate 2 drives gear plate 1 to rotate to the next motor shaft and fall onto the guide plate.

[0015] As a preferred embodiment of the present invention, the bottom of the guide plate is provided with a discharge port, an extension plate is fixed on the guide plate and along its inclined surface, a storage hopper communicating with the top of the outer shell is fixed, a support frame is fixed on the outer shell, and the support frame is fixed on the base.

[0016] As a preferred embodiment of the present invention, the bearing ring is fixed to the base by a support plate.

[0017] As a preferred embodiment of the present invention, the inclined plate is provided with a through hole for the motor shaft detection, and the inclined plate is provided with a cross-shaped slide groove, and the cross-shaped slider is connected in the cross-shaped slide groove by a spring.

[0018] As a preferred embodiment of the present invention, it further includes a drive assembly comprising a gear meshing with a gear ring, the gear being driven by a motor fixed to a base.

[0019] As a preferred embodiment of the present invention, the data detected by the laser measuring instrument is transmitted to the terminal via a wireless network.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. Achieving fully automatic continuous detection and significantly improving efficiency: This invention drives the rotating component to rotate through the driving component, and synchronously links the feeding component and the limiting component: Every time the rotating component rotates once, the toothed plate two drives the toothed plate one of the feeding component to rotate, so that the next motor shaft in the rotating drum automatically falls into the guide inclined plate; at the same time, the arc plate triggers the limiting component to release the limit on the measured motor shaft, so that it can be automatically fed out. The whole process does not require manual intervention, realizing a continuous cycle of "feeding-measuring-feeding", which significantly improves the efficiency of batch detection.

[0022] 2. All components work in a coordinated and precise manner. The gears and gear rings of the drive component mesh to ensure stable rotation of the rotating component. The laser measuring instrument can scan 360° around the motor shaft, improving the comprehensiveness of the measurement. The intermittent transmission between the second and first gear plates ensures that only one motor shaft is conveyed each time, avoiding material stacking. The pressing fit between the arc plate and the connecting column ensures that the cross-shaped slider of the limiting component is reliably limited during measurement and automatically released after measurement, achieving precise synchronization between limiting and unloading.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0037] like Figures 1 to 12 As shown, the present invention provides a laser measurement device for the inspection of motor parts, comprising:

[0038] Base 1;

[0039] The feeding assembly 2 includes a housing 21, with a rotating cylinder 22 rotatably connected inside the housing 21. The rotating cylinder 22 has a storage cavity for storing the motor shaft evenly arranged in a ring shape inside. A conical disk 23 is fixed to one end of the rotating cylinder 22 that passes through the housing 21. A toothed plate 24 corresponding to the storage cavity is evenly distributed in a ring shape on the inclined surface of the conical disk 23. A guide plate 25 communicating with the bottom of the housing 21 is fixed. A discharge port 26 is opened at the bottom of the guide plate 25. An extension plate 27 is fixed on the guide plate 25 and along its inclined surface. A storage hopper 28 communicating with the top of the housing 21 is fixed. A support frame 29 is fixed on the housing 21 and fixed on the base 1.

[0040] The bearing assembly 3 includes a bearing ring 31. When the motor shaft is fed from the guide plate 25, the central axis of the motor shaft coincides with the central axis of the bearing ring 31. The bearing ring 31 is fixed to the base 1 by a support plate 32.

[0041] The rotating assembly 4 includes a rotating ring 41. The inner wall of the rotating ring 41 has a track groove 42 for accommodating the bearing ring 31. The rotating ring 41 is fixedly sleeved with a toothed ring 43 and a conical ring 44 distributed back and forth. The conical ring 44 is fixedly sleeved with a toothed plate 45 that drives the toothed plate 24 to rotate to the next position. Two symmetrically distributed laser measuring instruments 46 are fixed on the rotating ring 41. The rotating ring 41 is also fixed with a fixed ring 47 coaxial with it. An arc-shaped plate 48 is fixedly sleeved on the periphery of the fixed ring 47.

[0042] The limiting component 5 includes an inclined plate 51 fixed on the base 1. The inclined plate 51 has a through hole 52 for the motor shaft to pass through after detection. The inclined plate 51 has a cross-shaped groove 53. A cross-shaped slider 54 slides inside the cross-shaped groove 53. The cross-shaped slider 54 is connected to the cross-shaped groove 53 by a spring 55. A connecting post 56 is fixed on the cross-shaped slider 54. The side of the connecting post 56 away from the cross-shaped slider 54 is attached to the outside of the fixed ring 47. When the fixed ring 47 and the arc plate 48 rotate, the arc plate 48 presses the connecting post 56 until the cross-shaped slider 54 no longer blocks one end of the motor shaft.

[0043] The drive assembly 6 includes a gear 61 that meshes with a gear ring 43, the gear 61 being driven by a motor 62 fixed to the base 1;

[0044] When batch testing of the motor shaft diameter is required, the operator first activates the control switch of motor 62, which drives gear 61 to rotate. Since gear 61 and gear ring 43 are meshed, when gear 61 rotates, it drives gear ring 43 to rotate, thus rotating the entire rotating assembly 4. During rotation, two laser measuring instruments 46 within the rotating assembly 4 perform laser measurements around a portion of the motor shaft that slides out from the discharge port 26. The diameter of the motor shaft measured by the laser measuring instruments 46 is transmitted to a computer terminal and compared with the diameter of a qualified motor shaft. If it is within the allowable error range, it is qualified; if it exceeds the error range, the diameter of the motor shaft is unqualified. Each rotation of the rotating assembly 4 will cause the arc plate 48 on the fixed ring 47 to lift the connecting column 56, causing the cross-shaped slider 54 to move upward. The upward movement of the cross-shaped slider 54 will no longer obstruct one end of the motor shaft, and the motor shaft will pass through the through hole 52. At the same time as the rotating assembly 4 rotates once, the toothed plate 25 will push the toothed plate 24 on the conical disk 23 to rotate by a certain angle, thereby causing the rotating drum 22 to rotate by a certain angle. At this time, the motor shaft inside the rotating drum 22 will tilt and fall along the guide inclined plate 25 until one end of the motor shaft abuts against the cross-shaped slider 54, thereby performing laser measurement and detection on the next motor shaft, realizing continuous measurement of the motor shaft, which greatly improves the measurement efficiency.

[0045] The core of this device lies in using the power output of the drive component 6 to synchronously rotate the component 4, the unloading component 2, and the limiting component 5, thereby achieving a closed-loop cycle of "loading-measuring-unloading". The specific process is as follows:

[0046] Step 1: Material preparation; the staff put the motor shafts to be tested into the storage hopper 28 in batches. The motor shafts slide along the inner wall of the storage hopper 28 into the outer shell 21 and fall naturally into the storage cavity of the rotating drum 22.

[0047] In the initial state, one of the storage chambers of the rotating drum 22 is aligned with the inlet of the guide plate 25. The motor shaft in the storage chamber slides down along the guide plate 25 until one end abuts against the limiting surface of the cross-shaped slider 54. At this time, the central axis of the motor shaft coincides with the central axis of the bearing ring 31 and the rotating ring 41, and is in the position to be measured.

[0048] Step 2: Laser measurement stage; Start the motor 62 of the drive component, which drives the gear 61 to rotate.

[0049] Gear 61 drives gear ring 43 to rotate, causing the entire rotating assembly 4 to rotate along the track groove 42 of bearing ring 31. At this time, two symmetrically distributed laser measuring instruments 46 on the rotating ring 41 make a 360° circular motion around the motor shaft, emitting laser beams to scan the surface of the motor shaft.

[0050] The laser measuring instrument 46 collects the diameter data of the motor shaft in real time and transmits it to the terminal system via wireless network. The terminal compares the measured data with the preset standard value, automatically determines whether the motor shaft is qualified, and records the test results.

[0051] Step 3: The measured motor shaft is cut; for each rotation of the rotating assembly 4, the arc plate 48 on the fixed ring 47 rotates synchronously with it. When the protruding part of the arc plate 48 contacts the connecting column 56, it gradually squeezes the connecting column 56.

[0052] When the connecting column 56 is subjected to force, it pushes the cross-shaped slider 54 to slide upward along the cross-shaped groove 53, and the spring 55 is further compressed; when the arc plate 48 rotates to the highest point, the cross-shaped slider 54 is completely retracted into the cross-shaped groove 53, releasing the restriction on the motor shaft.

[0053] Under the guidance of gravity and the inclined plane of the guide plate 25, the motor shaft slides out of the inclined plate 51 along the through hole 52 to complete the unloading. The diameter of the through hole 52 is slightly larger than the maximum diameter of the motor shaft to ensure smooth passage without jamming.

[0054] Step 4: Loading the next motor shaft; while the rotating assembly 4 rotates one revolution, the toothed plate 45 on the conical ring 44 rotates synchronously with it. When the toothed plate 45 contacts the toothed plate 24 on the conical disk 23, it pushes the toothed plate 24 to rotate around the central axis of the rotating cylinder 22 by a certain angle, which is equal to the distance between two adjacent toothed plates 24. In this embodiment, it is 60°.

[0055] The toothed plate 24 drives the rotating drum 22 to rotate synchronously by 60°, so that the next storage chamber in the rotating drum 22 is aligned with the inlet of the guide plate 25. The motor shaft in the storage chamber slides down the guide plate 25 under the action of gravity.

[0056] The extension plate 27 on the guide sloping plate 25 can prevent the motor shaft from shifting during the downward movement, ensuring that its central axis is always aligned with the bearing ring 31. When the motor shaft slides to the end, one end rests against the reset cross-shaped slider 54. At this time, the arc plate 48 has rotated past the connecting column 56, and the spring 55 resets and pushes the cross-shaped slider 54 out of the sloping plate 51, entering the measurement state.

[0057] Step 5: Cyclic detection; Repeat steps 2 to 4, and the device continues to complete the "measurement-feeding-loading" cycle until all motor shafts in the storage hopper 28 have been detected.
