Description

Technical Field

[0001] The utility model relates to the technical field of fan blade processing, in particular to a fixture for drilling holes in fan blade processing. Background Art

[0002] The main function of the fan blades is to be driven by the motor to rotate and generate wind for cooling or ventilation. Whether it is a table fan or a ceiling fan, the fan blades are driven by the motor to rotate, thereby cutting the air to generate wind and achieve the effect of cooling or ventilation.

[0003] When making fan blades, it is necessary to drill holes in the fan blades so that the fan blades can be installed on the output end of the motor. When drilling holes in the fan blades, it is necessary to first fix the fan blades with a clamp. Most of the existing clamps clamp the fan blades by moving the positions of two clamps. In order to prevent the fan blades from rotating when drilling holes, this clamping method usually requires the fan blades to be clamped tightly. Some fan blades are made of plastic or thinner metal, and their materials are relatively soft. Clamping with too much force can easily cause the fan blades to deform, which is inconvenient to use. In order to solve this technical problem, the utility model proposes a clamp for fan blade processing and drilling. Utility Model Content

[0004] The main purpose of the utility model is to provide a fixture for drilling holes in fan blades, which can effectively solve the problems mentioned in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A fixture for processing and drilling holes in fan blades comprises a base, the upper surface of the base is connected to a baffle, the upper surface of the base is slidably connected to a clamping plate, so a power mechanism is provided inside the base, the outer surface of the clamping plate is connected to a limiting shell, the interior of the limiting shell is slidably connected to a plug, the interior of the limiting shell is connected to a spring, the interior of the plug is slidably connected to a tooth plate, the outer surface of the tooth plate is meshed with teeth, the upper surface of the tooth plate is connected to a transmission rod, the upper surface of the tooth plate is slidably connected to the limiting plate, the outer surface of the limiting plate is connected to a sliding rod, and the interior of the base is slidably connected to a collecting shell.

[0007] Preferably, the power mechanism includes a motor, which is mounted on the outer surface of the base. The output end of the motor is connected to a threaded rod, and the outer surface of the threaded rod is rotatably connected to the interior of the base.

[0008] Preferably, the outer surface of the threaded rod is threadedly connected to a transmission block, the outer surface of the transmission block is slidably connected to the interior of the base, and the upper surface of the transmission block is connected to the bottom surface of the clamping plate.

[0009] Preferably, the outer surface of the clamping plate is slidably connected to the outer surface of the baffle, the bottom surface of the limiting shell is slidably connected to the upper surface of the base, and the outer surface of the plug is slidably connected to the inside of the clamping plate.

[0010] Preferably, one end of the spring away from the limiting shell is connected to the outer surface of the plug, the outer surface of the tooth plate is connected to the internal sliding rod of the limiting shell, and the teeth are installed inside the limiting shell.

[0011] Preferably, a transverse plate is connected to the interior of the base, and the outer surface of the sliding rod is slidably connected to the interior of the limiting shell.

[0012] Preferably, the outer surface of the plug is connected with a blocking block, and the outer surface of the limiting plate is slidably connected to the interior of the plug.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the utility model, through the cooperation between the clamping plate and the plug and other components, first the clamping plate can be moved. When it is necessary to limit the position of the fan blades, the fan blades can be slightly clamped by moving the clamping plate, so that the fan blades cannot move laterally. The plug can limit the position of the fan blades. After the clamping plate clamps the fan blades, the plug can be moved to the hole in the fan blade for mounting the fan blades. After the plug is moved to a position where it cannot be moved, the two sides of the plug will block the hole for mounting the fan blades, so that the fan blades will not rotate when drilling. At the same time, there is no need to clamp the fan blades too tightly to limit the position of the fan blades. This is very convenient and solves the problem that the fan blades are easily deformed when clamped too tightly.

[0015] In the utility model, through the cooperation between the tooth plate and the collection shell and other components, the tooth plate can be moved first. After the plug is moved to the appropriate position, the tooth plate can be moved to engage with the teeth by moving the tooth plate, thereby limiting the position of the plug and making it unable to move easily. The collection shell can collect debris generated during drilling. When drilling the fan blades, the debris generated by drilling will fall into the collection shell under the obstruction of the baffle and the splint. In this way, when cleaning the debris, the user only needs to pull the collection shell out from the base and pour out the debris inside the collection shell to complete the cleaning of the device. It is very easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1-5 As shown, a fixture for drilling holes in fan blades includes a base 1, a baffle 2 is connected to the upper surface of the base 1, and a splint 3 is slidably connected to the upper surface of the base 1. The base 1 fixes the position of the baffle 2 so that the baffle 2 cannot move. The baffle 2 is relatively high, and the debris generated during drilling is difficult to fly out of the baffle 2. The base 1 can provide support for the splint 3.

[0024] Therefore, a power mechanism 4 is provided inside the base 1, and the outer surface of the splint 3 is connected to the limit shell 5, and the inside of the limit shell 5 is slidably connected to the plug 6. The splint 3 will fix the position of the limit shell 5, and when the splint 3 moves, it will move with the limit shell 5. The limit shell 5 will limit the direction in which the plug 6 can move, so that the plug 6 cannot move easily. The plug 6 looks like a triangle when viewed from top to bottom. When the plug 6 is inserted into the hole for mounting the fan blade in the fan blade, the oblique edge of the plug 6 will block the fan blade, so that the fan blade cannot rotate.

[0025] The interior of the limiting shell 5 is connected to a spring 7, and the interior of the plug 6 is slidably connected to a tooth plate 8. The limiting shell 5 will limit the position of the spring 7, and the plug 6 will limit the position where the tooth plate 8 can move, so that the position of the tooth plate 8 will not deviate.

[0026] The outer surface of the tooth plate 8 is engaged with teeth 9, and the upper surface of the tooth plate 8 is connected to the transmission rod 10. After the tooth plate 8 is engaged with the teeth 9, the tooth plate 8 cannot move laterally, thereby limiting the position of the tooth plate 8. The tooth plate 8 will limit the position of the transmission rod 10. The transmission rod 10 moves upward to move with the tooth plate 8, and the tooth plate 8 is separated from the teeth 9 by moving the transmission rod 10.

[0027] The upper surface of the tooth plate 8 is slidably connected to a limit plate 11, and the outer surface of the limit plate 11 is connected to a slide rod 12. The inside of the base 1 is slidably connected to a collection shell 13. The limit plate 11 can block the top of the tooth plate 8, so that the tooth plate 8 cannot move upward when it does not need to be separated from the teeth 9. The limit plate 11 will fix the position of the slide rod 12, and when the slide rod 12 moves, it will move with the limit plate 11. The base 1 can provide support for the collection shell 13, and the debris generated during drilling will fall into the collection shell 13, and the collection shell 13 can be pulled out from the base 1.

[0028] The power mechanism 4 includes a motor 401, which is installed on the outer surface of the base 1. The output end of the motor 401 is connected to a threaded rod 402. The outer surface of the threaded rod 402 is rotatably connected to the inside of the base 1. The base 1 will fix the position of the motor 401 so that the motor 401 cannot move. The motor 401 will fix the position of the threaded rod 402, and when the motor 401 starts, it will rotate with the threaded rod 402. The base 1 will limit the position to which the threaded rod 402 can move, so that the threaded rod 402 will not generate large vibrations when it rotates.

[0029] The outer surface of the threaded rod 402 is threadedly connected to a transmission block 403, and the outer surface of the transmission block 403 is slidably connected to the inside of the base 1. The upper surface of the transmission block 403 is connected to the bottom surface of the splint 3. When the threaded rod 402 rotates, the transmission block 403 can be moved. The base 1 will limit the position to which the transmission block 403 can move. The movement of the transmission block 403 will move with the splint 3, and the splint 3 can prevent the transmission block 403 from rotating.

[0030] The outer surface of the splint 3 is slidably connected to the outer surface of the baffle 2, the bottom surface of the limit shell 5 is slidably connected to the upper surface of the base 1, and the outer surface of the plug 6 is slidably connected to the inside of the splint 3. The baffle 2 will limit the box of the splint 3, the base 1 will provide support for the limit shell 5, and the splint 3 will limit the direction in which the plug 6 can move.

[0031] The end of the spring 7 away from the limit shell 5 is connected to the outer surface of the plug 6, the outer surface of the tooth plate 8 is connected to the internal sliding rod of the limit shell 5, and the teeth 9 are installed inside the limit shell 5. The spring 7 provides thrust for the plug 6 so that the plug 6 can be automatically inserted into the fan blade. The limit shell 5 will limit the direction in which the tooth plate 8 can move, and the limit shell 5 will fix the position of the teeth 9.

[0032] The interior of the base 1 is connected with a horizontal plate 14, and the outer surface of the slide rod 12 is slidably connected to the interior of the limit shell 5. The base 1 will fix the position of the horizontal plate 14 so that the horizontal plate 14 cannot move, and provide support for the fan blades through the horizontal plate 14. The limit shell 5 will limit the direction in which the slide rod 12 can move, so that the movement of the limit shell 5 will not deviate.

[0033] The outer surface of the plug 6 is connected to a blocking block 15, and the outer surface of the limit plate 11 is slidably connected to the inside of the plug 6. The plug 6 will fix the position of the blocking block 15 so that the blocking block 15 cannot move. The blocking block 15 limits the movable position of the limit plate 11, so that the limit plate 11 cannot be moved out of the plug 6. The plug 6 can limit the direction in which the limit plate 11 can move.

[0034] Working principle: When using this device, you first need to place the fan blades on the horizontal plate 14, then start the motor 401 to rotate the threaded rod 402. The rotation of the threaded rod 402 will cause the transmission block 403 to move with the clamping plate 3 to a position where the fan blades are about to be clamped. Then the plug 6 is inserted into the fan blades under the action of the spring 7, and then the fan blades are clamped by the clamping plate 3. Then the user needs to move the slide rod 12 to the position where the limit plate 11 contacts the blocking block 15, so that the tooth plate 8 will drop and engage with the teeth 9, and then the limit plate 11 can be reset.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
