Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal fan blade detection, in particular to a conveying mechanism for a centrifugal fan blade automatic detection line. Background Art

[0002] Centrifugal fan blades are an important component used in fans, ventilation equipment and air-conditioning systems. They are also called fan wheels. They are usually made of thin metal sheets or plastics, fan-shaped or blade-shaped, rotating around a central axis and connected by circular connecting pieces. They are designed to generate airflow or wind when rotating to increase air flow, increase air pressure or achieve other wind power effects.

[0003] The automatic inspection line for centrifugal fan blades is an automated production line used to inspect centrifugal fan blades in order to detect their dynamic balance during rotation. The conveying mechanism is a device that sends the centrifugal fan blade originals to the inspection point through the transmission mechanism for automated inspection and processing.

[0004] In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. Currently, the dynamic balance test of the fan blades usually involves installing the workpiece separately on the output end surface used for driving. This operation method increases the working time and thus affects the working efficiency; 2. Since the axis of the centrifugal fan blades are of different sizes, it will cause inconvenience when connecting with the output end surface of the drive. It may be necessary to select a matching drive device based on the axis of the centrifugal fan blades, which lacks flexibility. Utility Model Content

[0005] The purpose of the utility model is to provide a conveying mechanism for an automatic inspection line for centrifugal fan blades, so as to solve the problems that the dynamic balancing test proposed in the above-mentioned background technology usually involves installing the workpiece separately on the output end surface for driving, which increases the working time, and cannot be adjusted according to the size of the axis, resulting in a lack of flexibility. To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a conveying mechanism for an automatic detection line of centrifugal fan blades, comprising a track, wherein gears are rotatably connected inside the track, a toothed belt is meshed on one side of the gear, an internal connector is glued on the surface of the toothed belt, an external connector is welded on the top of the internal connector, and the external connector is slidably connected to the surface of the track, a hydraulic column is provided below the track, one end of the hydraulic column is connected to the bottom surface of the track by bolts, and the other end of the hydraulic column is connected to the top surface of the mounting base by bolts, a main panel is welded below the external connector, a bearing is provided inside the main panel, and a blade mounting plate and a drive member mounting plate are respectively welded to the bearing through a connecting shaft rod running through the axis thereof, the blade mounting plate and the drive member mounting plate are respectively located at two ends of the main panel, a magnetic stone is connected to the surface of the drive member mounting plate by bolts, an adjusting splint is provided inside the blade mounting plate, one end of the adjusting splint is rotatably connected to a screw, and the screw is threadedly connected to the inside of the blade mounting plate.

[0006] Further preferably, the track is elliptical, and the internal connecting parts are slidably connected to the slide grooves on the inner wall of the track through pulleys at both ends, and a through hole for connecting the internal connecting parts with the external connecting parts is opened through the middle of the track, and the track forms a lifting structure above the mounting base through a hydraulic column.

[0007] Further preferably, the gears are distributed along the four corners of the track, and a transmission structure is formed between the gears through a toothed belt.

[0008] Further preferably, the blade mounting plate and the driving member mounting plate are rotatably connected to the two ends of the main panel through a connecting shaft, and circular through holes that are interconnected and connected are respectively provided on the surfaces of the driving member mounting plate and the magnetic stone.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] In the utility model, compared with the linear conveying mechanism, the elliptical track has a longer path and does not occupy too much space. At the same time, the hydraulic column is used to adjust the working height of the track and the operating table surface according to the position of the external detection equipment used to drive the blades, thereby improving the flexibility of equipment use. The structure of the protective cover not only reduces the operating steps to play a protective effect, but also can indirectly detect whether the rotating blades are offset due to imbalance.

[0013] In the utility model, the detection equipment of the driving blade is inserted through the through holes on the surface of the driving component mounting plate and the magnetic stone. Since the outer shell of the motor is mostly made of metal, the magnetic stone has good adsorption capacity for metal.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figures 1 to 5 The utility model provides a technical solution: a conveying mechanism for an automatic detection line of centrifugal fan blades, comprising a track 1, a gear 2 is rotatably connected inside the track 1, a toothed belt 3 is meshed on one side of the gear 2, an internal connector 4 is glued and connected to the surface of the toothed belt 3, an external connector 5 is welded on the top of the internal connector 4, and the external connector 5 is slidably connected to the surface of the track 1, a hydraulic column 6 is provided below the track 1, one end of the hydraulic column 6 is connected to the bottom surface of the track 1 by bolts, and the other end of the hydraulic column 6 is connected to the top of the mounting base 7 by bolts. A main panel 8 is welded below the external connecting part 5, a bearing 9 is provided inside the main panel 8, a blade mounting plate 11 and a driving member mounting plate 12 are respectively welded to the bearing 9 through a connecting shaft 10 running through the axis center thereof, the blade mounting plate 11 and the driving member mounting plate 12 are respectively located at two ends of the main panel 8, a magnetic stone 13 is connected to the surface of the driving member mounting plate 12 by bolts, an adjusting splint 14 is provided inside the blade mounting plate 11, one end of the adjusting splint 14 is rotatably connected to a screw 15, and the screw 15 is threadedly connected to the inside of the blade mounting plate 11.

[0022] In this embodiment, Figure 1 and Figure 3 As shown, the track 1 is elliptical, and the internal connector 4 is slidably connected to the slide groove of the inner wall of the track 1 through the pulleys at both ends thereof, and a through hole for connecting the internal connector 4 with the external connector 5 is provided in the middle of the track 1. At the same time, the track 1 forms a lifting structure above the mounting base 7 through the hydraulic column 6; compared with the linear conveying mechanism, the elliptical track 1 has a longer path and does not occupy too much land space, so that the workpiece can move a longer distance on the track 1. After the part that clamps the workpiece at the bottom conveys the workpiece to the inspection point through the transmission structure, the inspector can classify the workpiece according to compliance or non-compliance based on the inspection results, and the part can be transmitted to the initial point again to load a new workpiece.

[0023] In this embodiment, Figure 2As shown, the gears 2 are distributed along the four corners of the track 1, and the gears 2 are connected by toothed belts 3 to form a transmission structure; the structure of the toothed belt 3 enables it to provide better grip and transmission efficiency during the transmission process, and compared with the chain transmission structure, it can generate less noise and vibration. Since the dynamic balance detection is mainly through the rotating blades to observe whether it has vibration or imbalance, the use of the toothed belt 3 is more advantageous for detection.

[0024] In this embodiment, Figure 1 and Figure 4 As shown, the blade mounting plate 11 and the driver mounting plate 12 are rotatably connected to the two ends of the main panel 8 through the connecting shaft 10, and the surfaces of the driver mounting plate 12 and the magnetic stone 13 are respectively provided with circular through holes that are interconnected. For the current dynamic balancing detection, the detection workpiece is installed with the driving end. Because the installation steps are many, a certain amount of time will be added, thereby reducing the efficiency of the detection. A suitable driving motor can be selected according to the aperture of the driving member mounting plate 12, and the output end of the driving motor can be inserted through the through holes on the surfaces of the driving member mounting plate 12 and the magnetic stone 13. Since the outer shell of the motor is mostly made of metal, the magnetic stone 13 has good adsorption properties for metal, and the blade mounting plate 11 and the driver mounting plate 12 are welded as a whole through the connecting shaft 10. When one side rotates, the other side rotates at the same time, thereby greatly reducing the installation steps.

[0025] In this embodiment, Figure 5 As shown, a cavity for slidingly connecting an adjusting clamp 14 is provided on one side of the inner wall of the blade mounting plate 11, and the adjusting clamp 14 forms a lifting structure in the cavity of the blade mounting plate 11 through a screw 15, and one end of the screw 15 passes through the bottom of the blade mounting plate 11; the blades are rotated and distributed around the central axis and connected through a circular connecting piece. When they are inserted into the through hole in the blade mounting plate 11, due to the different diameter specifications of the middle circular connecting piece, the adjustment purpose is achieved by adding an adjusting clamp 14. The adjusting clamp 14 is made of rubber material and has anti-slip properties. Its arc shape can fit well on the edge of a circular object. Its position in the middle through hole of the blade mounting plate 11 can be adjusted by the screw 15 to clamp the axis of the internal blade. When processing blade workpieces with different axis specifications, the beneficial effect of quickly fitting and fixing the workpiece is achieved without replacing parts, reducing the installation steps in the detection, thereby improving the overall work efficiency.

[0026] In this embodiment, Figure 1 and Figure 4As shown, a protective cover 16 is provided on one side of the outer wall of the main panel 8, and a limit hook 17 is provided below the protective cover 16, and a clockwork spring is provided inside the protective cover 16; in order to avoid accidents when the blades rotate, the protective cover 16 is added to provide protection for the inspectors. The protective cover 16 is made of polyurethane, which is lightweight and has good cutting resistance. The clockwork spring structure in the prior art is adopted inside the protective cover. The clockwork spring is supported by a metal belt and curled into a spiral shape. When the protective cover 16 is pulled downward, the internal spring is applied with external force and then stretched, causing elastic deformation of the spring. After the limit hook 17 is lost, the external force is lost, and the internal spring pulls the protective cover 16 to close under the reset structure. If the blade vibrates during the detection process, it will collide or rub against the protective cover 16 when it is unstable. Therefore, the structure of the protective cover 16 not only reduces the operating steps and plays a protective effect, but also can indirectly detect whether the rotating blades are offset due to imbalance.

[0027] The use method and advantages of the utility model: The conveying mechanism used in the centrifugal fan blade automatic detection line, when in use, the working process is as follows:

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, first, the device can be fixed on the surface of the operating table by installing the base 7, and the hydraulic column 6 is used to adjust the working height of the track 1 and the operating table surface according to the position of the external detection device for driving the blade. First, the first operator inserts the blade workpiece into the through hole of the blade mounting plate 11, and according to the size of the workpiece axis, the screw 15 is rotated to adjust the position of the adjusting clamp 14 in the internal through hole of the blade mounting plate 11 until the adjusting clamp 14 fits the edge of the workpiece, and the output end of the servo motor drives the gear 2 on one side to rotate, and under the structure of the toothed belt 3, the array gears 2 rotate at the same time, so that the toothed belt 3 drives the internal connecting piece 4 to slide in the inner wall groove of the track 1, and the corresponding external connecting piece 5 drives the blade mounting plate 11 and the main panel 8 clamping the workpiece below to drive The moving part mounting plate 12 is transmitted to the detection point. When it reaches the detection point, the first operator can continue to install the second group of blades, and the second operator who has been transmitted to the detection point can pull the added protective cover 16 to engage its front end ring with the surface of the limit hook 17, and insert the driving device for detection through the through hole on the surface of the driving part mounting plate 12 and the magnetic stone 13. After turning on the power, under the connection of the connecting shaft 10, the driving part mounting plate 12 rotates to drive the front end blade mounting plate 11 to rotate, thereby causing the blade workpiece inside the blade mounting plate 11 to rotate. The second operator can observe whether the rotating blade meets the standard and selectively eliminate it, and then after completing the inspection, disassemble the workpiece to classify it, and the external connecting part 5 drives the lower parts to be transmitted to the initial point again to load new workpieces.

[0029] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
