Description

Technical Field

[0001] The utility model relates to the technical field of motor rotor detection, in particular to a motor rotor multi-position exposed clamping device adapted for industrial camera defect detection. Background Art

[0002] The motor rotor is the rotating part in the motor. The motor consists of two parts: the motor rotor and the stator. It is a device used to realize the conversion of electrical energy into mechanical energy and mechanical energy into electrical energy. The motor rotor is divided into two types: the inner motor rotor rotation mode and the outer motor rotor rotation mode. The inner motor rotor rotation mode is that the core in the middle of the motor is the rotating body, outputting torque or receiving energy. The outer motor rotor rotation mode is that the outer body of the motor is the rotating body. Different modes facilitate the application in various occasions. The motor rotor needs to be inspected for appearance after production. By inspecting the appearance of the motor rotor, problems with the motor rotor can be discovered in time, preventing the motor rotor from being damaged or deformed during subsequent long-term work, and improving the overall performance of the motor.

[0003] In the prior art, most motor rotor inspection methods still rely on manual inspection. The appearance problems of motor rotors are as small as millimeter level or even smaller. Traditional inspection methods are prone to miss inspections, and the inspection standards are highly subjective. In order to ensure a comprehensive inspection of the appearance of the motor rotor during manual inspection of the motor rotor, it is necessary to change the exposed position of the motor rotor to form an appearance showing different positions from the axial direction or radial direction. However, the manual continuous operation of changing the position of the motor rotor can only stay in the small test stage, and the collected data is limited. The manual operation holding posture is not uniform and prone to blind spots. It is not possible to achieve unified collection of standardized axial and radial multi-position exposed states. The collected image position is not continuous enough, and it is difficult to collect the corresponding position twice, and subsequent screening, identification and classification are required. The cracking and deformation of the internal defects of the motor rotor are also difficult to find through visual inspection. In short, in the acquisition of motor rotor images, there is a lack of standardized tools that can adapt to the motor rotor for axial and radial multi-position conversion and on-demand conversion. Summary of the invention

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a motor rotor multi-position exposed clamping device adapted for industrial camera defect detection.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

Two first clamping plates are symmetrically installed on the outer wall of the double-headed screw, and a bottom clamping gap that matches the electronic rotor is formed between the two first clamping plates.

[0009] As a preferred solution: two rotating plates are rotatably mounted on the top of the movable frame, first cleaning brushes are mounted on the bottom of the two rotating plates, and two fixed plates are mounted on the top of the movable frame near the two rotating plates.

[0010] As a preferred solution: a cushion is arranged on the inner side of each second splint, the two cushions are arranged opposite to each other, and two through grooves are symmetrically provided inside the two second splints and the cushions, and the length direction of the through grooves is in the same direction as the height direction of the second splints.

[0011] As a preferred solution: two guide rails are installed on the outer wall of each second splint, sliders are slidably installed at the bottom of the two guide rails, moving blocks are commonly installed at the bottom ends of the two sliders, and second cleaning brushes are installed at one end of the two moving blocks located at the through slot.

[0012] As a preferred solution: the two moving blocks are each provided with an inclined surface at one end away from the through slot, two protrusions are installed on the outer wall of each second clamping plate, sliding rods are slidably installed inside the two protrusions, and abutting blocks abutting against the inclined surface of the moving blocks are installed at the top of the two sliding rods, and springs are installed on the outside of the two sliding rods.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The utility model forms a multi-position positioning and clamping state of the motor rotor through the cooperation between the support frame, the mobile frame, the first clamping mechanism, the second clamping mechanism, the electric telescopic rod and the second clamping plate. The clamping method is specially used to adapt to the external structural characteristics of the motor rotor, forming a multi-position and multi-angle clamping process for the motor rotor in the axial or radial direction, which is beneficial to the multi-angle image acquisition process of the motor rotor and the formation of standardized and unified acquisition data, and can also repeatedly acquire data at any position and angle.

[0017] When dust and other dirt adhere to the surface of the motor rotor, which affects the camera's accurate detection of the motor rotor surface, the two second cleaning brushes arranged inside the two second clamps are extended and in contact with the outer wall of the motor rotor. As the round table drives the motor rotor to rotate, the dust and other dirt adhered to the surface of the motor rotor can be cleaned by multiple second cleaning brushes, making it convenient for the camera to continue to detect and identify its appearance.

[0018] After long-term use, a small amount of debris will be attached to the outer walls of the two soft pads.

The two first cleaning brushes are driven by the driving screw to clean the debris on the outer walls of the two soft pads, which is convenient for the subsequent use of the two soft pads.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

This device can convert the clamping method of the motor rotor without manual intervention, which is beneficial to comprehensively and multi-directionally collect the image data of the motor rotor. Through the cooperation of this device, it can ensure that the shaft and radial positions of the clamped motor rotor are fully exposed, avoiding the lack of image information caused by the formation of blind spots on the outer surface. It can also be adjusted according to specific requirements for the exposed angle and position, with stable and unified repeatability, which is beneficial to accurately achieve full coverage detection of various appearance defects. The multi-position exposed device for motor rotors specifically includes a support frame 1. The support frame 1 is a U-shaped frame with its opening facing upwards. The support frame 1 includes a main board and two side boards. The main board is horizontally arranged, and the two side boards are vertically arranged side by side at both ends of the top surface of the main board. The support frame 1 formed by the main board and the two side boards has a three-sided open structure form that is adapted to the shooting of the industrial camera. The three open sides are the top surface and the two sides above the main board, which is beneficial for image collection when the motor rotor is clamped in different positions and presents different shaft and radial positions exposed. Slide grooves 2 are opened on the inner walls of both sides of the support frame 1. A moving frame 3 is slidably installed inside the two slide grooves 2. A first clamping mechanism for clamping and fixing the bottom end of the motor rotor is installed on the top of the moving frame 3. A second clamping mechanism for clamping and fixing both sides of the motor rotor is installed inside the support frame 1. The second clamping mechanism includes electric telescopic rods 6 installed on the inner walls of both sides of the support frame 1. Second clamping plates 7 are installed at the telescopic ends of the two electric telescopic rods 6. Two first driving motors are pre-installed inside the support frame 1, and the output ends of the two first driving motors are respectively connected to the two electric telescopic rods 6, so as to drive the electric telescopic rods 6 and the second clamping plates 7 to rotate.

[0031] As a technical optimization scheme in the present utility model, a driving lead screw 10 is installed inside one of the slide grooves 2, and the top end of the driving lead screw 10 passes through the moving frame 3. A second driving motor is preset at the bottom of the support frame 1, and the output end of the second driving motor is connected to the bottom end of the driving lead screw 10, so as to drive the driving lead screw 10 to rotate inside the slide groove 2, enabling the moving frame 3 to move up and down inside the support frame 1.

[0032] As a technical optimization scheme in the present utility model, the first clamping mechanism includes a frustum 4. The frustum 4 is rotatably installed at the center position on the top of the moving frame 3. A groove is opened on the top of the frustum 4, and a double-headed screw 13 is rotatably installed inside the groove. Two first clamping plates 12 are symmetrically installed on the outer wall of the double-headed screw 13. A third driving motor is preset inside the moving frame 3, and the output end of the third driving motor is connected to the center position of the frustum 4, so as to drive the frustum 4 to rotate; a first driving device is preset inside the frustum 4, and the output end of the first driving device is connected to one end of the double-headed screw 13, so as to drive the double-headed screw 13 to rotate, enabling the two first clamping plates 12 to move towards or away from each other.

[0033] Furthermore, each first clamping plate 12 is a vertical plate, and the opposing surfaces of the two are respectively processed with arc grooves. The inner wall of the arc groove is provided with an elastic gasket, which is used to form a slight deformation under pressure when clamping the motor rotor shaft, which is beneficial to improve the universal performance of clamping shafts with different outer diameters. The clamping method formed by the two arc grooves is used to match the shape of the shaft part of the electronic rotor, and can achieve the effects of full wrapping clamping and partial wrapping clamping at different relative distances.

[0034] As a technical optimization solution in the utility model, two rotating plates 5 are rotatably installed on the top of the mobile frame 3, and the bottom of the two rotating plates 5 are both installed with first cleaning brushes 9, and two fixed plates 11 are installed on the top of the mobile frame 3 near the two rotating plates 5. The two rotating plates 5 are rotatably connected to the top of the mobile frame 3 through electric rotating shafts arranged at both ends, and the two electric rotating shafts are connected to the output ends of the driving device preset outside the mobile frame 3, so that the two rotating plates 5 can be rotated and adjusted on the top of the mobile frame 3. The driving device is an existing driving device, and its working principle is the same as the working principle of the existing driving device.

[0035] As a technical optimization solution in the utility model, the outer wall of the two second clamping plates 7 close to each other is installed with a soft pad 8, and the two second clamping plates 7 and the soft pad 8 are symmetrically provided with two through grooves 20. The soft pad 8 arranged on the outer wall of the two second clamping plates 7 close to each other can ensure that the second clamping plates 7 are in flexible contact with the motor rotor to avoid damage to the motor rotor.

[0036] As a technical optimization solution in the utility model, two guide rails 14 are installed on the outer walls of the two second clamping plates 7 on the side away from each other, and sliders 22 are slidably installed at the bottom of the two guide rails 14. The bottom ends of the two sliders 22 are jointly installed with moving blocks 15, and the two moving blocks 15 are both installed with second cleaning brushes 21 at one end of the through slot 20. When the moving block 15 moves inside the through slot 20, the slider 22 located on the top thereof can guide and limit it to prevent the moving block 15 from falling off from the inside of the through slot 20.

[0037] As a technical optimization solution in the utility model, the ends of the two moving blocks 15 away from the through slot 20 are both provided with inclined surfaces, and the outer walls of the two second clamping plates 7 away from the sides are both equipped with two protrusions 19, and the insides of the two protrusions 19 are both slidably installed with slide bars 18, and the tops of the two slide bars 18 are both equipped with abutment blocks 16 that abut against the inclined surfaces of the moving blocks 15, and the outsides of the two slide bars 18 are both covered with springs 17. By pushing the slide bar 18 upward, the spring 17 is extended, and the abutment block 16 at the top of the slide bar 18 is driven to squeeze the inclined surface of the moving block 15, so that the second cleaning brush 21 on one side of the moving block 15 is extended from the inside of the through slot 20, and after the restriction on the slide bar 18 is released, the spring 17 is retracted and reset, so that the abutment block 16 moves downward and resets, and the second cleaning brush 21 on one side of the moving block 15 is retracted to the inside of the through slot 20.

[0038] In the utility model, when it is necessary to perform an appearance inspection on the motor rotor, the rotating shaft at one end of the motor rotor can be placed between the two first clamping plates 12, and the double-headed screw 13 is controlled to rotate, driving the two first clamping plates 12 to move in a direction close to each other, and the width of the bottom clamping gap becomes smaller until the rotating shaft at one end of the motor rotor is clamped and fixed; an industrial camera is preset on the front of the support frame 1, and the camera can perform an appearance inspection on the surface of the fixed motor rotor, and then the background system is used to analyze the image taken by the camera, so as to determine whether there are defects in the appearance of the motor rotor.

[0039] When the camera is photographing and inspecting the appearance of the motor rotor, the truncated table 4 can be controlled to drive the clamped motor rotor to rotate slowly, so that the camera can detect the appearance of the motor rotor more comprehensively; after the appearance of the motor rotor is inspected, the telescopic ends of the two electric telescopic rods 6 can be controlled to extend synchronously, driving the two second clamping plates 7 to move in a direction close to each other, making a relatively close action, and the top clamping gap formed between the two second clamping plates 7 is used to clamp and fix the outer sides of the motor rotor. At this time, the two first clamping plates 12 of the first clamping mechanism can be controlled to move in a direction away from each other, so that the two first clamping plates 12 release the clamping and fixing of the motor rotor shaft, and control the driving screw 10 to rotate and drive the moving frame 3 to move downward until it abuts against the inner bottom surface of the support frame 1, and start with the two first drive motors preset in the support frame 1, driving the two electric telescopic rods 6 and the second clamping plates 7 to rotate together, so that the motor rotor clamped and fixed by the two second clamping plates 7 can rotate with the electric telescopic rod 6 as the center of the circle, so that the camera can shoot and detect the shafts at both ends of the motor rotor, thereby achieving the effect of comprehensive and accurate detection of the overall appearance of the motor rotor.

[0040] When the rotating shaft at one end of the motor rotor is clamped and fixed by the two first clamping plates 12, after detection and identification by the camera, it is found that dust and other dirt are attached to the surface of the motor rotor, which affects the camera's accurate detection of the motor rotor surface, the driving screw 10 can be controlled to rotate and drive the moving frame 3 to move upward, so that the two rotating plates 5 in a horizontal state at this time move upward together, pushing the bottom ends of the two sets of sliding rods 18 upward, driving the spring 17 to extend, and driving the abutment block 16 at the top of the sliding rod 18 to squeeze the inclined surface of the moving block 15, so that the second cleaning brushes 21 on one side of the multiple moving blocks 15 are all moved from the corresponding The through slot 20 extends out from the inside, controlling the telescopic ends of the two electric telescopic rods 6 to extend together, pushing the two second clamping plates 7 to move in a direction close to each other, so that the bottom ends of the two sets of slide bars 18 slide to the top of the fixed plate 11 at the top of the two rotating plates 5 respectively. At this time, multiple second cleaning brushes 21 extending from the through slot 20 are in contact with the outer wall of the motor rotor, and the control table 4 drives the motor rotor to rotate together, so that in the process of the motor rotor contacting with the multiple second cleaning brushes 21, the dust and other dirt attached to its surface are automatically cleaned, which is convenient for the subsequent camera to continue to detect and identify its appearance.

[0041] After the two soft pads 8 are used for a long time, a small amount of debris will be attached to the outer wall of the side close to each other. After the use of the utility model, the two rotating plates 5 are controlled to rotate upward to a vertical state, so that the first cleaning brushes 9 arranged at the bottom of the two rotating plates 5 are close to the two soft pads 8 respectively, and the telescopic ends of the two electric telescopic rods 6 are controlled to drive the two second clamping plates 7 to move in the direction of approaching each other, so as to drive the two soft pads 8 to contact the two first cleaning brushes 9 respectively, and the moving frame 3 is driven up and down by means of the driving screw 10, so as to drive the two first cleaning brushes 9 to clean the debris on the outer walls of the two soft pads 8, so as to facilitate the subsequent use of the two soft pads 8.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
