DETAILED DESCRIPTION

[0017] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the embodiments of the present application will be described in detail below with reference to the drawings, but the embodiments described in the present application are part of the embodiments of the present application, not all the embodiments.

[0018] Embodiment 1

[0019] The embodiment of the present application provides a rotating shaft detection device for detecting the outer shape size of a motor rotating shaft, as shown in the drawings, which comprises a detection mechanism 1, a storage rack 2 and the like. Figs. 1-3

[0020] ​The detection mechanism 1 comprises a feeding plate 11 and a first driving part 13, a plurality of placement grooves 12 with a length adapted to the length of the shaft are arranged on the feeding plate 11, and the placement grooves 12 are arranged in an array along the length direction of the feeding plate 11; the first driving part 13 is used for driving the feeding plate 11 to move along the length direction of the feeding plate 11, and the first driving part 13 can adopt a linear motor, and the specific driving mode can be selected as step or servo driving to ensure the accurate positioning of the feeding plate 11; a detection part 14 is arranged above the feeding plate 11, and the shafts in the placement grooves 12 can be sequentially detected in size. The storage rack 2 comprises a pair of mounting rods 21 which are detachably arranged above the feeding plate 11, when the mounting rods 21 are arranged above the feeding plate 11, the mounting rods 21 are arranged towards the length direction of the feeding plate 11; a plurality of pairs of bearing rods 22 which are arranged in an array along the length direction of the mounting rods 21 and are adapted to the placement grooves 12 are arranged between the two mounting rods 21, and at least one bearing rod 22 in each pair of bearing rods 22 is arranged to move along the length direction of the mounting rods 21.

[0021] As shown in Fig. 1 , the storage rack 2 serves as a transfer piece between the incoming material warehouse and the detection device, when taking out the material, the distance between each pair of bearing rods 22 is smaller than the diameter of the shaft, and a plurality of shafts can be taken out and placed between each pair of bearing rods 22; the storage rack 2 carrying the shafts is arranged above the feeding plate 11, at this time, the mounting rods 21 are arranged towards the length direction of the feeding plate 11, the bearing rods 22 are arranged towards the length direction of the placement grooves 12, the first driving part 13 drives the feeding plate 11 to move along the length direction of the feeding plate 11 to below the storage rack 2, until the placement grooves 12 are respectively below the corresponding bearing rods 22; at least one bearing rod 22 in each pair of bearing rods 22 starts to move along the length direction of the mounting rods 21, so that the distance between the two bearing rods 22 in each pair of bearing rods 22 is increased, thereby making all the shafts on the storage rack 2 fall into the corresponding placement grooves 12 at one time; the first driving part 13 drives the feeding plate 11 to move reversely, so that the shafts on the feeding plate 11 pass below the detection part 14 in sequence to be detected in size. Through the arrangement of the storage rack 2 and the detection mechanism 1, and through the cooperation between the bearing rods 22 and the placement grooves 12, the transfer of the shafts can be completed at one time, so that the feeding efficiency of the shafts and the detection efficiency of the detection part are greatly improved, thereby improving the production efficiency of the motor.

[0022] Embodiment 2

[0023] As a further embodiment of the above embodiment 1, specifically, as shown in Figs. 1-3As shown, the two mounting rods 21 are provided with a number of matching grooves 23 on the opposite sides, and the number of the matching grooves 23 is consistent with the number of the bearing rods 22. The matching grooves 23 are arranged in an array along the length direction of the bearing rods 22. The movable shafts 24 are coaxially arranged in the mounting rods 21, and the movable shafts 24 are arranged to move along the axis of the movable shafts 24 and pass through the matching grooves 23. The movable shafts 24 are provided with a plurality of matching blocks 25, and the matching blocks 25 are respectively arranged to slide in the corresponding matching grooves 23 along the length direction of the mounting rods 21. The two ends of one bearing rod 22 on the same side of each pair of bearing rods 22 are respectively connected to the corresponding matching blocks 25. The one end of each movable shaft 24 extends to the outside of the mounting rod 21 and is perpendicularly connected to the push plate 26. The spring 27 is arranged on the movable shaft 24 and is connected to the push plate 26 and the end of the mounting rod 21. When the spring 27 is in a natural state, the distance between the two bearing rods 22 in each pair of bearing rods 22 is less than the diameter of the shaft.

[0024] In use, as shown in the figure, Figs. 1-3 When the first driving part 13 drives the feeding plate 11 to move along the length direction of the feeding plate 11 to the lower side of the storage rack 2, the side plate 111 pushes the push plate 26 and moves the movable shaft 24 along the axis of the movable shaft 24 against the elasticity of the spring 27, so as to drive the matching blocks 25 to move in the matching grooves 23. The distance between the two bearing rods 22 in each pair of bearing rods 22 starts to increase, but the two bearing rods 22 can still effectively bear the shaft. Until the placing grooves 12 are respectively moved to the lower side of the corresponding bearing rods 22, the distance between the two bearing rods 22 in each pair of bearing rods 22 is too large to bear the shaft, so that the shaft is respectively dropped into the corresponding placing groove 12. After the shaft is transferred, the bearing rods 22 are automatically reset under the action of the spring 27, so as to be ready for reloading the shaft. Under the action of the side plate 111 and the push plate 26, and in cooperation with the movable shaft 24 and the matching block 25, the movement of the feeding plate 11 can be converted into the synchronous movement of each bearing rod 22, so that the shaft on the bearing rod 22 can be simultaneously and effectively dropped into the corresponding placing groove 12, which further improves the feeding efficiency and optimizes the structure of the detection device. At the same time, under the action of the spring 27, the matching block 25 can be automatically reset, which improves the convenience of the detection device.

[0025] Specifically, as shown in the figure, Figs. 1-3 The two sides of the feeding plate 11 are provided with the support plates 3, and the two mounting rods 21 are respectively detachably arranged on the corresponding support plates 3. The specific connection mode of the support plates 3 and the mounting rods 21 can adopt a structure such as a bolt or a buckle. The support plates 3 are provided with the positioning blocks 31, and the bottoms of the two mounting rods 21 are respectively provided with the positioning grooves 28 matched with the positioning blocks 31. Through the cooperation of the positioning blocks 31 and the positioning grooves 28, the storage rack 2 can be quickly positioned to the correct position, which simplifies the installation process of the storage rack 2 and effectively improves the detection efficiency.

[0026] Since the rotating shaft is a precision part, collision may occur when it falls into the placing groove 12, which may cause scratches and bumps on the outer surface of the rotating shaft. A certain buffer component can be arranged on the placing groove 12, or the distance between the storage rack bearing rod 22 and the placing groove 12 can be reduced. When the distance between the bearing rod 22 and the placing groove 12 is close, the two bearing plates 22 may clamp the rotating shaft that falls into the placing groove 12 after the spring 27 drives the movable shaft 24 to move reversely, which may cause transfer failure.

[0027] The preferred mode of lifting the support plate 3 is adopted in the embodiment, which is as follows: as shown in Fig. 1 and Fig. 3 , a second driving part 4 is arranged below the support plate 3, which can drive the two support plates 3 to move synchronously in a direction perpendicular to the feeding plate 11. The second driving part 4 can adopt a linear cylinder, an electric cylinder or other linear mechanisms. When the feeding plate 11 moves to the lower side of the storage rack 2, the second driving part 4 drives the storage rack 2 to descend to approach the placing groove 12, so as to stably place the rotating shaft on the bearing plate 22 into the placing groove 12. After the placing is completed, the second driving part 4 drives the support plate 3 to move upward, so that the bearing rod 22 is away from the placing groove 12, and then the first driving part 13 drives the feeding plate 11 to move reversely, and correspondingly, the side plate 111 and the push plate 26 are in sliding fit in a direction perpendicular to the feeding plate 11. Through the arrangement of the second driving part 4, the problems of scratches, bumps and clamping of the rotating shaft by the bearing plate 22 can be effectively avoided, and the rotating shaft feeding process is optimized.

[0028] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Obviously, those skilled in the art can make various modifications and changes to the present application without departing from the spirit and scope of the present application.
