Description

Technical Field

[0001] This utility model relates to the field of fan blade processing technology, specifically a fan blade connecting hole drilling fixture. Background Technology

[0002] Fan blades are an important component of fans. Driven by an electric motor, they rotate to generate airflow, achieving cooling, ventilation, or air circulation. The design and materials of fan blades have a significant impact on fan performance and noise levels. Their basic structure typically includes the blades themselves and the shaft connecting the blades. They come in a variety of types and are widely used in household appliances, industrial equipment, and other fields requiring ventilation and cooling.

[0003] When machining fan blades, holes need to be drilled on their surface for connection with the motor's output shaft. A fixture is needed to fix them in place during drilling. However, the drilling process generates debris, which takes time to clean manually, thus slowing down the overall processing efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a drilling fixture for fan blade connection holes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows.

[0006] A jig for drilling fan blade connection holes includes a base and a turntable. A servo motor is installed inside the base, and a first electric push rod is mounted at the end of the servo motor's output shaft. The telescopic end of the first electric push rod is connected to the lower surface of the turntable. Three through holes are formed at equal angles to the center on the surface of the turntable. Four through slots are formed at equal angles to the center around the through holes on the surface of the turntable. A sliding rod is installed inside each through slot. A connecting plate is slidably mounted on the outer surface of the sliding rod. A spring is sleeved on the outer surface of the sliding rod, with both ends of the spring abutting against the inner wall of the through slot and the connecting plate, respectively. A clamping block is mounted on the upper end of the connecting plate, and a wedge-shaped extrusion block is mounted on the lower end of the connecting plate. Two collection bowls are mounted on the upper surface of the base, and the two collection bowls are coaxially aligned with the two through holes, and the collection bowls are press-fitted with the wedge-shaped extrusion block. A cleaning mechanism is provided on the outer side of the base.

[0007] Furthermore, the cleaning mechanism includes a fixed plate installed on the outer surface of the base, an L-shaped plate on the top of the fixed plate, a fan installed on the upper surface of the L-shaped plate, an adsorption tube running through the interior of the horizontal plate of the L-shaped plate, and a collection bag detachably connected between the adsorption tube and the suction end of the fan.

[0008] Furthermore, a rotating sleeve is rotatably mounted at the bottom of the adsorption tube, a brush plate is mounted on the lower surface of the rotating sleeve, bristles are provided on the outer surface of the brush plate, a toothed ring is mounted on the outer surface of the rotating sleeve, a drive motor is mounted on the outer surface of the adsorption tube, and a drive gear is mounted at the end of the output shaft of the drive motor, and the drive gear meshes with the toothed ring.

[0009] Furthermore, the L-shaped plate is slidably installed inside the fixed plate, and a second electric push rod is installed on the outer surface of the fixed plate. The end of the telescopic end of the second electric push rod is connected to the lower surface of the L-shaped plate.

[0010] Furthermore, a rubber pad is provided on the inner side of the clamping block, and the outer surface of the rubber pad is provided with anti-slip texture.

[0011] Furthermore, the collection bowl and the base are detachably connected.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0013] 1. This utility model, through the design of the through hole, allows some of the debris generated during drilling to fall directly into the collection bowl for collection. Through the design of the cleaning mechanism, the debris remaining on the upper surface of the fan blade can be adsorbed, thus achieving the purpose of automatic debris cleaning, reducing the workload of workers, and improving the overall processing efficiency.

[0014] 2. This utility model uses a first electric push rod to drive the turntable to descend, causing the wedge-shaped extrusion block to press against the collection bowl, which in turn drives the four clamping blocks to converge inward simultaneously, achieving automatic clamping of the fan blades. When the first electric push rod drives the turntable to rise, the spring force can drive the four clamping blocks to move away from each other and release the clamping, thereby improving the clamping efficiency of the fan blades.

[0015] 3. This utility model uses a servo motor to drive the turntable to rotate, which can realize the cyclic operation of three sets of clamping blocks. It can perform the subsequent fan blade placement operation in advance during the fan blade drilling process, thus further improving the processing efficiency. Attached Figure Description

[0023] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0024] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0025] like Figure 1-5As shown, a fan blade connection hole drilling fixture includes a base 100 and a turntable 102. A servo motor is installed inside the base 100, and a first electric push rod 101 is installed at the end of the output shaft of the servo motor. The end of the telescopic end of the first electric push rod 101 is connected to the lower surface of the turntable 102. Three through holes 103 are formed at equal angles to the center on the surface of the turntable 102. Four through slots 104 are formed at equal angles to the center around the through holes 103 on the surface of the turntable 102. A slide rod 105 is installed inside the through slot 104. A connecting plate 106 is slidably installed on the outer surface of the slide rod 105. A spring 107 is sleeved on the outer surface of the slide rod 105. The two ends of the spring 107 abut against the inner wall of the through slot 104 and the connecting plate 106, respectively. A clamping block 108 is installed at the upper end of the connecting plate 106, and a wedge-shaped pressing block 109 is installed at the lower end of the connecting plate 106. Two collection bowls 110 are installed on the upper surface of the base 100, and the two collection bowls 110 are coaxially arranged with the two through holes 103 respectively, and the collection bowls 110 are pressed and engaged with the wedge-shaped pressing block 109. A cleaning mechanism 200 is provided on the outer side of the base 100.

[0026] In use, the worker first places the fan blade on the through hole 103 without a corresponding collection bowl 110, and inside the four clamping blocks 108. Then, the servo motor drives the turntable 102 to rotate 120 degrees and enter the drilling processing station (not shown in the figure). At this time, the fan blade to be processed rotates to the top of the collection bowl 110. Then, the first electric push rod 101 drives the turntable 102 to descend, so that the wedge-shaped extrusion block 109 can be pressed against the inner wall of the collection bowl 110, causing the four clamping blocks 108 to converge inward and clamp on the outside of the middle disc part of the fan blade to achieve fixation. Then, drilling can be performed. Some of the debris generated by drilling can fall directly into the collection bowl 110 through the through hole 103 for collection. In addition, during the processing of the fan blade, the worker can place the fan blade to be processed in advance.

[0027] After the fan blades have been drilled, the first electric push rod 101 drives the turntable 102 to rise, causing the wedge-shaped extrusion block 109 to separate from the collection bowl 110. At this time, under the elastic force of the spring 107, the four clamping blocks 108 are pushed away from each other, releasing the fixation on the fan blades. Then, the servo motor drives the turntable 102 to rotate 120 degrees, and the fan blades to be processed, which were placed in advance, rotate to the drilling station. The fan blades that have completed drilling rotate to the bottom of the cleaning mechanism 200. Subsequently, the first electric push rod 101 drives the turntable 102 to descend. Through the extrusion of the wedge-shaped extrusion block 109 and the collection bowl 110, the two fan blades can be fixed at the same time. Therefore, the cleaning mechanism 200 can be used to clean the debris remaining on the upper surface of the fan blades, thus reducing the workload of workers and improving the overall processing efficiency. Then, the servo motor drives the turntable 102 to rotate 120 degrees again, releasing the fixation on the processed fan blades, which can then be taken out and placed back.

[0028] Preferably, the cleaning mechanism 200 includes a fixing plate 201 installed on the outer surface of the base 100, an L-shaped plate 202 is provided on the top of the fixing plate 201, a fan 203 is installed on the upper surface of the L-shaped plate 202, an adsorption tube 204 is provided through the interior of the horizontal plate of the L-shaped plate 202, and a collection bag 205 is detachably connected between the adsorption tube 204 and the suction end of the fan 203.

[0029] When the fan 203 is started, the suction force it generates acts on the end of the adsorption tube 204, thus adsorbing the debris remaining on the upper surface of the fan blades and collecting it in the collection bag 205.

[0030] Preferably, a rotating sleeve 300 is rotatably mounted on the bottom of the adsorption tube 204, a brush plate 301 is mounted on the lower surface of the rotating sleeve 300, bristles are provided on the outer surface of the brush plate 301, a toothed ring 302 is mounted on the outer surface of the rotating sleeve 300, a drive motor 303 is mounted on the outer surface of the adsorption tube 204, a drive gear 304 is mounted on the end of the output shaft of the drive motor 303, and the drive gear 304 is meshed with the toothed ring 302.

[0031] When the blower 203 adsorbs debris, the drive motor 303 can be started. The drive motor 303 drives the drive gear 304 to rotate. Since the drive gear 304 meshes with the gear ring 302, it can drive the brush plate 301 to rotate, clean the surface of the fan blades, remove the debris still connected to the fan blades and adsorb it into the collection bag 205, thus improving the cleaning effect of debris.

[0032] Preferably, the L-shaped plate 202 is slidably installed inside the fixed plate 201, and a second electric push rod 400 is installed on the outer surface of the fixed plate 201. The end of the telescopic end of the second electric push rod 400 is connected to the lower surface of the horizontal plate of the L-shaped plate 202.

[0033] The L-shaped plate 202 can be raised and lowered by the second electric push rod 400, and the height of the adsorption tube 204 and the brush plate 301 can be adjusted. Therefore, it can clean and adsorb debris from fan blades of different sizes and specifications, and is highly flexible.

[0034] Preferably, the inner side of the clamping block 108 is provided with a rubber pad, and the outer surface of the rubber pad is provided with anti-slip texture.

[0035] The rubber pads and anti-slip texture not only improve the clamping effect on the fan blades, but also prevent excessive pressure on the fan blade surface, which could cause damage.

[0036] Preferably, the collection bowl 110 is detachably connected to the base 100.

[0037] Once the debris collected in the collection bowl 110 reaches a certain amount, it can be removed from the base 100 for debris disposal, making it convenient to use.

[0038] The above is a detailed description of the present invention in conjunction with specific embodiments, and it should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, any equivalent substitutions or obvious modifications made without departing from the concept of the present invention, and which have the same performance or use, should be considered as falling within the patent protection scope defined by the submitted claims.
