Description
Technical Field
The utility model relates to a fan blade axle is dismantled with drawing horse ware.
Background
The puller is a tool frequently used in mechanical maintenance. Mainly for axially removing damaged bearings from the shaft. Mainly comprises a rotating handle, a screw rod and a pulling claw. The bearing has two claws and three claws, and the main sizes are the length of the pulling claw, the distance between the pulling claws and the length of the screw rod so as to adapt to bearings with different diameters and different axial installation depths. The existing puller has the defect that the puller is inconvenient to use due to the limitation of maintenance space in the process of disassembling and using the fan blade shaft bearing.
SUMMERY OF THE UTILITY MODEL
Based on the above-mentioned defect that prior art exists, the to-be-solved technical problem of the utility model is to provide a fan blade axle is dismantled with drawing horse ware, its structure is more simple, convenient to use.
In order to realize the purpose of the utility model, the utility model adopts the following technical scheme:
the utility model provides a fan blade axle is dismantled with drawing horse ware, include:
a screw rod used for pushing the tip part against the motor shaft when the fan blade shaft is disassembled;
set up in first steel disc and the second steel disc in screw rod middle part: the first steel disc is arranged on the upper surface of the second steel disc: a plurality of through holes for fixedly connecting bolts with the fan blade shaft are formed in the second steel disc; and
fixing a structural part: including being located second disc below respectively and running through the first fixed knot structure that the screw rod set up and set up in the second fixed knot structure of screw rod tip, first fixed knot structure and second fixed knot structure all with screw rod fixed connection.
As a further improvement of the utility model: the inner diameter of the first steel disk is smaller than that of the second steel disk, and the outer diameter of the second steel disk is at least 5 times of the outer diameter of the screw.
As a further improvement of the utility model: the first steel disc and the second steel disc are perpendicular to the screw rod, and are of an integrated structure.
As a further improvement of the utility model: the fixed connection is connected in a welding mode.
As a further improvement of the utility model: the first fixed structural part and the second fixed structural part have the same structure and are both prism-shaped.
The utility model provides a fan blade axle is dismantled with drawing horse ware, simple structure compares in traditional drawing horse ware, and accessible bolt lug connection avoids the centre gripping blade to cause the deformation to damage at the fan blade epaxial for the structure is more simple, convenient to use.
Drawings
Fig. 1 is a schematic structural view of a puller for detaching a fan blade shaft according to the present invention;
fig. 2 is the structural schematic diagram of the operating state of the utility model used in cooperation of the puller and the fan blade shaft for disassembling the fan blade shaft.
Detailed Description
The following is to the utility model provides a fan blade axle is dismantled and is used puller device to do further more detailed explanation through concrete embodiment:
example 1
Referring to fig. 1 and 2, the puller for detaching the fan blade shaft of the present embodiment includes:
a screw 1 for pushing the tip part against the motor shaft when the fan blade shaft is disassembled;
set up in first steel disc and second steel disc 2 in screw rod middle part: the first steel disc is arranged on the upper surface of the second steel disc 2: a plurality of through holes for fixedly connecting bolts with the fan blade shaft are formed in the second steel disc 2; and
fixing a structural part: including being located second disc below respectively and running through first fixed knot component 3 that the screw rod set up and setting up in the second fixed knot component 4 of screw rod tip, first fixed knot component 3 and second fixed knot component 4 all with screw rod 1 fixed connection.
The inner diameter of the first steel disk is smaller than that of the second steel disk 2, and the outer diameter of the second steel disk 2 is at least 5 times of that of the screw.
First steel disc and the equal perpendicular screw rod 1 setting of second steel disc 2, and first steel disc and second steel disc 2 are the integral structure, and the purpose is the manufacturing of being convenient for.
The fixed connection is connected in a welding mode.
The first fixed structural part 3 and the second fixed structural part 4 have the same structure, and are both prism-shaped, and the outer hexagon is 36 mm in this embodiment.
As shown in fig. 2, the fan blade shaft comprises a fan blade shaft body 5 with a hollow structure and a blade 6 arranged on the fan blade shaft body 5, the fan blade shaft body 5 and the blade 6 are of an integrated structure, the fan blade shaft body 5 is sleeved on the motor shaft through the hollow structure, and is difficult to detach after long-term use, and often needs the assistance of a puller, the traditional puller is inconvenient in use due to limited operation space and accessory protection, when the puller is used, the tip of the screw rod 1 is positioned at the top of the shaft end of the motor, the through hole on the second steel disc 2 is connected with the screw hole 7 on the fan blade shaft body 5 through a bolt, after the second steel disc 2 is fastened with the fan blade shaft body 5, the rear end of the puller rotates the rear end through other tools such as a wrench and the like to rotate the screw rod 1 of the puller, and the second steel disc 2 is tightly fixed with the fan blade shaft body 5, so that the fan blade shaft is pulled to be separated from the motor shaft.
It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes, modifications and/or alterations to the present invention may be made by those skilled in the art after reading the technical disclosure of the present invention, and all such equivalents may fall within the scope of the present invention as defined by the appended claims.
