[0002] The verticality of a motor, also known as the verticality of the axis line, refers to the verticality between the motor shaft and the mounting surface of the bracket, which is one of the important indicators for measuring the quality of the motor. Therefore, it is very important to detect the roundness and verticality of the inner diameter of the overall mounting surface of the motor bracket to ensure the concentricity between the motor shaft and the mounting surface of the bracket, thereby meeting the accuracy requirements. In the prior art, a roundness detector is usually used to detect the inner diameter roundness of the mounting surface of the motor bracket, and then a verticality detector is used to detect the verticality of the mounting surface of the motor bracket. The operation of separate devices is extremely inconvenient, and the operation complexity is relatively high.

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be described clearly and completely in combination with the technical solution in the embodiments of the utility model. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0029] The utility model is implemented as follows Figures 1 to 8 As shown in, a motor support verticality detection machine includes a machine platform 1, on which is provided a lifting and rotating mechanism 2, a lifting and limiting mechanism 3, a rotating limiting mechanism 4 and a visual inspection mechanism 5; the lifting and limiting mechanism 3 is located above the lifting and rotating mechanism 2, and the rotating limiting mechanism 4 is located between the lifting and limiting mechanism 3 and the lifting and rotating mechanism 2; the lifting and rotating mechanism 2 is used to lift the motor support 100 and drive the motor support 100 to rotate, the lifting and limiting mechanism 3 is used to vertically contact with the axis of the motor support 100 when the motor support 100 is lifted to limit the lifting and lowering of the motor support 100, and the rotating limiting mechanism 4 is used to rotationally contact with the axis of the motor support 100 when the motor support 100 is lifted to limit the rotation of the motor support 100; the visual inspection mechanism 5 is close to the rotating limiting mechanism 4 and is used to obtain an image of the motor support 100 during the rotation process.

[0030] When the motor bracket 100 is lifted up by the lifting and rotating mechanism 2 and the motor bracket 100 is rotated, the lifting and lowering limit mechanism 3 and the rotation limit mechanism 4 can lift and rotate the axis of the motor bracket 100, and then the visual inspection mechanism 5 can be used to capture an image of the rotating motor bracket 100. After cooperating with the system main controller to realize image recognition and analysis, it can be confirmed whether the verticality of the motor bracket 100 is qualified, and it can also be judged whether the concentricity of the motor bracket 100 meets the requirements, thereby facilitating rapid detection of whether the motor bracket 100 is a qualified product.

[0031] In this embodiment, the lifting and rotating mechanism 2 is arranged on the upper surface of the machine 1, and a support frame 11 is also provided on the upper surface of the machine 1. The shape of the support frame 11 is an inverted U shape, and the two bottom ends of the support frame 11 face downward and are fixed on the upper surface of the machine 1, and the two bottom ends of the support frame 11 are correspondingly located at the front and rear sides of the lifting and rotating mechanism 2.

[0032] Specifically, in this embodiment, the lifting and rotating mechanism 2 includes a first lifting cylinder 21 and a rotating cylinder 22. The lower end of the first lifting cylinder 21 is arranged on the upper surface of the machine table 1, and the upper end of the first lifting cylinder 21 is provided with a lifting platform 211. The rotating cylinder 22 is arranged on the lifting platform 211, and the top plate of the support frame 11 is located above the rotating cylinder 22. The first lifting cylinder 21 controls and drives the lifting platform 211 to perform lifting motion. Furthermore, the rotating cylinder 22 is driven to rise or fall through the lifting platform 211. Among them, the function of the rotating cylinder 22 is to drive the rotation of the rotating shaft thereon. When the lower end of the motor bracket 100 is cooperatively connected with the rotating shaft thereon, the motor bracket 100 can be jacked up and driven to rotate during the rising process.

[0033] Specifically, in this embodiment, the lifting limit mechanism 3 includes a second lifting cylinder 31 and a limit rod 32. The second lifting cylinder 31 is arranged on the upper surface of the top plate of the support frame 11. The limit rod 32 is connected to the driving end of the second lifting cylinder 31 and penetrates through the top plate of the support frame 11. The lower end of the limit rod 32 is located below the top plate of the support frame 11 and corresponds to the rotating cylinder 22. The second lifting cylinder 31 can control the lifting motion of the limit rod 32 to facilitate adjusting the position height of the limit rod 32, and further facilitate limiting the motor bracket 100 with different shaft lengths.

[0034] Among them, the limit rod 32 is cylindrical, and a limit guide post 321 is further arranged at the lower end of the limit rod 32. The diameter of the limit guide post 321 is smaller than the diameter of the shaft of the motor bracket 100.

[0035] Specifically, in this embodiment, the rotation limit mechanism 4 includes a translation cylinder 41 and a limit block 42 arranged oppositely. The translation cylinder 41 and the limit block 42 are arranged on the lower surface of the top plate of the support frame 11, one on the left and the other on the right. The translation cylinder 41 adopts an existing structure composed of a slider and a cylinder driving member. In actual application, two rotating rollers 411 are arranged on the side of the slider opposite to the limit block 42, so that the two rotating rollers 411 can be horizontally moved by driving the slider to move. A vertical groove 421 is formed on the side of the limit block 42 opposite to the two rotating rollers 411. There is a gap for accommodating the shaft of the motor bracket 100 between the two rotating rollers 411 and the groove 421. After the first lifting cylinder 21 and the rotating cylinder 22 cooperate to jack up the motor bracket 100, the shaft of the motor bracket 100 enters the gap and is limited by the limit guide post 321. Then, by moving the two rotating rollers 411 towards the limit block 42 until the shaft of the motor bracket 100 is limited between the two rotating rollers 411 and the groove 421, the two rotating rollers 411 are in contact with and cooperate with the rotation of the shaft of the motor bracket 100, so as to facilitate the motor bracket 100 to always maintain a smooth rotating action.

[0036] Further, a horizontal card slot is also provided on one side of the limit block 42 opposite to the two rotating rollers 411. The depth of the card slot is less than that of the groove 421. The distance between the inner top surface and the inner bottom surface of the card slot is such that the rotating roller 411 can extend into it and rotate therein. Through the position cooperation of the groove 421, the card slot and the rotating roller 411, the shaft of the motor bracket 100 is in a clamped state, so that the shaft of the motor bracket 100 can rotate in the space formed by the groove 421, the card slot and the rotating roller 411, making the motor bracket 100 not prone to displacement, so as to improve the detection quality. In this embodiment, the limit block 42 is in an L shape.

[0037] Specifically, in this embodiment, the vision detection mechanism 5 includes two relatively arranged vision detection cameras. The two vision detection cameras are arranged corresponding to each other in the front and back along the length direction of the top plate of the support frame 11, and the lenses of the two vision detection cameras face each other. Among them, the two vision detection cameras are correspondingly located in front of and behind the limit rod 32. The limit rod 32 is located between the two vision detection cameras, and the translation cylinder 41 and the limit block 42 are also both located between the two vision detection cameras. The central connection line between the two vision detection cameras is perpendicular to the central connection line between the translation cylinder 41 and the limit block 42. In this embodiment, the vision detection camera is, for example, a CCD (Charge-coupled Device) camera.

[0038] Further, a jig table translation mechanism 6 is also provided on the machine table 1. The jig table translation mechanism 6 is used to move the jig table carrying the motor bracket 100 to the position where the lifting and rotating mechanism 2 is located along the X-axis direction. Specifically, the jig table translation mechanism 6 is, for example, a slide rail assembly. For example, a slide rail frame is arranged on the upper surface of the machine table 1 along the left-right direction (i.e., the X-axis direction) of the machine table 1. The jig table slides on the slide rail frame and is driven to translate by a motor or a cylinder, so that the jig table approaches or moves away from the position where the lifting and rotating mechanism 2 is located along the X-axis direction. After the motor bracket 100 is detected, the first lifting cylinder 21 and the rotating cylinder 22 are reset, and then the jig table is controlled to move back to the original position to receive the next motor bracket 100 to be detected.

[0039] Further, a first clamping mechanism 7 is also provided on the machine table 1. The first clamping mechanism 7 includes a first moving module 71 and a first clamping jaw module 72. The first moving module 71 is connected to the first clamping jaw module 72 and drives the first clamping jaw module 72 to move along the Y-axis direction to transfer the motor bracket 100 to be detected to the position where the jig table is located. A second clamping mechanism 8 is also provided on the machine table 1. The second clamping mechanism 8 includes a second moving module 81 and a second clamping jaw module 82. The second moving module 81 is connected to the second clamping jaw module 82 and drives the second clamping jaw module 82 to move along the Y-axis direction to transfer the measured motor bracket 100 to the qualified product placement area or the unqualified product placement area.

[0040] Specifically, in this embodiment, the first clamping mechanism 7 and the second clamping mechanism 8 are respectively located on the left and right sides of the lifting and rotating mechanism 2, and the jig table translation mechanism 6 is located between the first clamping mechanism 7 and the lifting and rotating mechanism 2, facilitating feeding from the left and discharging from the right. Further, the discharging on the right is divided into discharging of non-conforming products and discharging of conforming products. For example, if the second clamping mechanism 8 conveys the material downward after picking up, the conveyed products are conforming products; if the second clamping mechanism 8 conveys the material upward after picking up, the conveyed products are non-conforming products. In order to facilitate the batch collection and processing of non-conforming products, for example, a conveyor belt module 9 arranged along the X-axis direction at the rear position on the upper surface of the machine table 1 is used to convey non-conforming products, while the direct transfer of conforming products facilitates the next process and effectively improves the classification and processing efficiency of conforming products and non-conforming products in automatic detection. Among them, the specific conveying or transfer method can be designed and selected according to actual application requirements. The attached drawings are only examples and do not constitute specific limitations.

[0041] Among them, both the first moving module 71 and the second moving module 81 can adopt existing slide rail assemblies composed of a slide rail frame and driving parts such as motors or cylinders to drive the corresponding first jaw module 72 and second jaw module 82 to move along the Y-axis direction (i.e., the front and rear direction of the machine table 1). Moreover, both the first jaw module 72 and the second jaw module 82 can also adopt any existing suitable jaw module to pick up the motor bracket 100 and move it to the corresponding position.

[0042] It should be noted that the structure of the conveyor belt module 9 is also relatively common. In actual application, any existing suitable conveyor belt module 9 composed of a conveyor belt can be referred to to convey the motor bracket 100, and it will not be elaborated and specifically limited in this embodiment.

[0043] In this embodiment, "cooperating with the system master controller to realize the recognition and analysis of images" can be achieved by using any existing suitable system master controller and image analysis technology, and the system master controller can be set at any suitable position on the machine table 1 or on other relevant mechanisms and equipment, and no specific limitations are made in this embodiment.

[0044] It should be understood that for ordinary skilled workers in the art, improvements or transformations can be made according to the above description, and all such improvements and transformations should fall within the protection scope of the appended claims of the present invention.
