The substrate 100 provides a mounting base for each component of the fixture, and the substrate 100 may be made of an alloy material. Referring to fig. 1-2, it should be noted that the base plate 100 may include a first rectangular plate with a longer length and a second rectangular plate with a shorter length, the second rectangular plate is welded to one side of the first rectangular plate, and an "L" shaped structure is formed between the first rectangular plate and the second rectangular plate.
The floating retaining columns 200 play a role in positioning the fan blades, and the floating retaining columns 200 can be arranged at one end of the base plate 100 in a telescopic mode; in this embodiment, the floating spacer 200 is fixed in the second rectangular plate.
The tightening device 300 includes a tightening driver 320 and a nut sleeve 310, the nut sleeve 310 is disposed between the floating retaining columns 200, the nut sleeve 310 is used for accommodating a fan blade nut, and the tightening driver 320 is fixed on the base plate 100 and is used for driving the nut sleeve 310 to rotate so as to tighten the fan blade nut.
The displacement drive 400 is disposed on the base plate 100 to drive the tightening driver 320 away from or toward the floating spacer 200.
The clamp for the fan blade is characterized in that the base plate of the clamp is provided with the floating retaining columns 200, the floating retaining columns 200 can stretch out and draw back on the base plate 100, the floating retaining columns 200 can fix and position the fan blade with different reinforcing ribs, and the telescopic floating retaining columns 200 avoid interference between the clamp and the fan blade body, so that scratching and extrusion in the process of positioning and fixing the fan blade can be avoided. The tightening device 300 is started after the fan blades are fixed, the nut sleeve 310 is driven to rotate through the tightening driver 320, and the nut in the nut sleeve 310 can be tightened on the motor shaft, so that the fan blade nut and the motor shaft are locked, the defect of manually tightening the fan blade nut is overcome, and the production efficiency is improved. And the displacement driving device 400 can drive the tightening driver 320 to move, so that the position of the nut sleeve 310 can be changed, so as to better tighten and fix fan blades of different specifications and sizes, and further improve the application range of the clamp.
More specifically, in practice, the jig is used in combination with an industrial robot. The clamp is installed on an industrial robot, and the industrial robot drives the clamp to move to realize the screwing operation of the fan blade nut.

In the industry, reinforcing ribs are generally provided in the casing of the fan blade to enhance the structural stability. The arrangement positions of the fan blade reinforcing ribs with different shapes and sizes are also different. When the floating retaining columns 200 which are arranged into rectangles at intervals are actually applied, the floating retaining columns can be clamped between the reinforcing ribs of the fan blades and interact with the reinforcing ribs, so that the fan blades cannot rotate after being installed on a motor shaft. Because the floating barrier column 200 can be extended, when the floating barrier column 200 is used for fixing the fan blade, even if the floating barrier column 200 interferes with the reinforcing ribs, the floating barrier column 200 can be retracted under the action of the reinforcing ribs. The design avoids the rigid contact between the floating retaining column 200 and the fan blade reinforcing ribs, so that the fan blade cannot be damaged when the fan blade is fixed through the floating retaining column 200. Moreover, the floating retaining columns 200 which are distributed in a rectangular shape can also adapt to the fixation of fan blades in different forms and specifications, and the application range of the tool is enlarged. It should be noted that, in the process of fastening the floating retaining column 200 to the fan blade, the nut sleeve 310 is far away from the fan blade. After the floating retaining column 200 fixes the fan blade on the motor shaft, the displacement driving device 400 drives the tightening driver 320 to move, and the tightening driver 320 drives the nut sleeve 310 to approach the fan blade, so that the nut sleeve 310 corresponds to the motor shaft. After the nut sleeve 310 is embedded in the motor shaft, the nut adjusting sleeve is driven to rotate by the tightening driver 320, so that the fan blade nut can be screwed and fixed on the motor shaft, and the locking installation of the fan blade and the motor shaft is realized.

The displacement driving means 400 may be a cylinder.
Furthermore, N rows are arranged on the substrate 100 along the horizontal direction and M rows are arranged on the substrate 100 along the vertical direction by the plurality of floating barrier pillars 200, where M and N are both natural numbers greater than 1, and M and N are equal to or different from each other;

In order to consider the production cost and the fixing effect of the fan blade, M and N are usually 2 or 3. The limiting tube 220 is used for accommodating the buffer spring 230, and the limiting tube 220 can be fixed on the substrate 100 through bolts. After the buffer spring 230 is disposed in the limiting tube 220, it should be in a compressed state, that is, the buffer spring 230 generates an acting force on the substrate 100 to move the rubber head 2101 away from the limiting tube 220. Therefore, the length of the section of each column 210 exposed to the limiting tube 220 in the natural state is the same, and all the rubber heads 2101 are in the same plane. The rubber head 2101 can reduce the fish tail of fan blade when restricting the fan blade and removing.

Further, still include positioning mechanism 3, positioning mechanism 3 includes cylinder mounting panel 31, location cylinder 32 and locating plate 33, cylinder mounting panel 31 sets up on the transfer chain 1, location cylinder 32 is fixed cylinder mounting panel 31, locating plate 33 with the output fixed connection of location cylinder 32, location cylinder 32 drive the motion of locating plate 33, positioning mechanism 3 with stop mechanism 2 mutually supports and presss from both sides the tight fixing of air conditioner outer machine on the transfer chain 1. After the air conditioner external unit is moved to one side of the robot, the baffle plate 21 is lifted, and the air conditioner external unit is prevented from being conveyed continuously. After the baffle plate 21 stops the air conditioner external unit, the positioning cylinder 32 is started to drive the positioning plate 33 to press the air conditioner external unit to one side. It should be noted that the positioning mechanism 3 is arranged opposite to the blocking mechanism 2, that is, the positioning plate 33 presses the air conditioner external unit from the side opposite to the baffle plate 21 during positioning, so as to prevent the air conditioner external unit from shifting when the fan blade nut is screwed, which results in a screwing failure.
Further, the device also comprises a feeding mechanism 5, wherein the feeding mechanism 5 is arranged between the conveying line 1 and the robot, and the feeding mechanism 5 is used for providing fan blade nuts for the robot; the robot absorbs the fan blade nuts from the feeding mechanism 5, and the fan blade nuts are screwed on a motor shaft of an air conditioner external unit through the fan blade clamps.
The following explains the specific working process of the production line:
an air conditioner external unit sleeved with fan blades on a motor shaft is placed at the inlet end of the conveying line 1, the conveying line 1 is started, and the air conditioner external unit is driven by the conveying line 1 to move. And a photoelectric induction switch is arranged at the robot, and when the photoelectric induction switch senses that the air conditioner external unit is in place, the blocking mechanism 2 is started. The blocking cylinder 22 drives the baffle plate 21 to lift, and the air conditioner external unit is prevented from moving continuously. At the moment, the positioning cylinder 32 is also started to drive the positioning plate 33 to press the air conditioner from the side edge, and the positioning plate 33 and the baffle plate 21 work together to clamp the air conditioner outdoor unit.
After the air conditioner external unit is clamped and positioned, the robot main body 4 is started, and the robot main body 4 drives the clamp to the feeding mechanism 5 to absorb the fan blade nut. The nut sleeve 310 of the clamp sucks the fan blade nut and then reaches the side face of the fan blade reinforcing rib, and the fan blade is clamped by the reinforcing rib to complete the positioning of the fan blade. The displacement drive cylinder 420 then drives the movement of the tightening actuator 320, and the tightening actuator 320 drives the nut sleeve 310 toward the motor shaft. The robot main body 4 positions a specific position of the motor shaft by the visual positioning means 500 and makes the position of the nut socket 310 correspond to the position of the motor shaft. The tightening driver 320 continues to move until the nut socket 310 nests into the motor shaft. After the nut sleeve 310 is nested into the motor shaft, the screwing driver 320 is started to drive the nut sleeve 310 to rotate, and the fan blade nut is screwed into the motor shaft to complete the locking of the fan blade nut. In the tightening process, the fan blade cannot rotate due to the action of the floating retaining column 200, and the motor shaft cannot rotate under the limit of the fan blade, so that the tightening driver 320 can smoothly complete the tightening operation of the fan blade nut.
After the tightening operation is finished, the tightening driver 320 monitors the current passing through the inside of the tightening process, the current value is converted into a torque value, and an angle sensor and a counter can be installed at the tail end of a rotating shaft of the tightening driver 320 so as to output tightening monitoring parameters such as tightening torque, a rotating angle and tightening time. Finally, the displacement drives the air cylinder 420 to contract, and the nut sleeve 310 is separated from contact with the fan blade nut.
As another embodiment, the robot main body 4 detects whether the tightening of the nut satisfies the process requirement by determining whether data such as the tightening torque, the rotation angle, and the tightening time satisfies the process requirement. When the data are normal, the blocking mechanism 2 and the positioning mechanism 3 are released; when the robot is abnormal, the robot main body 4 gives an alarm, the blocking mechanism 2 and the positioning mechanism 3 are kept clamped and not released, and after the staff handles the abnormality, the manual operation is released.
In another embodiment, when the torque of the tightening driver 320 needs to be verified, the nut sleeve 310 is disassembled through the quick-release mechanism 700, the tightening data is verified by replacing the quick-release mechanism with a torque verification tool, and the nut sleeve 310 is reinstalled on the quick-release mechanism 700 after the verification is finished.
