Description

Puller

Technical Field

The utility model relates to a extracting tool field, concretely relates to draw horse ware.

Background

In daily production equipment maintenance, the tripod is usually used for dismounting belt pulleys, bearings, gears and other parts, and because the tripod works through the screw teeth on the screw rod, the bearing capacity of the screw is large, and the stress points of three buoys are not concentrated. There are usually two disadvantages in the use process of the tripod puller: firstly, damage accessories easily during the dismantlement, secondly the pulling force is not big, runs into the accessories that the magnitude of interference is big and pulls out at all motionless.

SUMMERY OF THE UTILITY MODEL

In summary, in order to overcome the deficiencies of the prior art, the present invention provides a device for pulling a horse.

The utility model provides an above-mentioned technical problem's technical scheme as follows: a puller comprises a pulling plate, a base and two pulling rods; the pulling plate and the base are oppositely arranged; the two pull rods are respectively arranged at the upper part and the lower part between the pull plate and the base, and the two ends of each pull rod are respectively connected with the corresponding positions of the pull plate and the base; and the pulling plate is provided with a notch matched with a shaft of the part to be disassembled.

On the basis of the technical scheme, the utility model discloses can also do following further improvement:

further, the base is a square bar structure formed by welding two steel grooves.

Further, the notch comprises a square part and a semi-circular part, the width of the square part is equal to the diameter of the semi-circular part, and the width of the square part and the diameter of the semi-circular part are matched with the radial size of the shaft of the part to be disassembled; one end of the square part is positioned in the middle of the outer edge of one side of the pulling plate, and the other end of the square part extends to the position of the circle center of the pulling plate; the semicircular part is communicated with the other end of the square part.

Furthermore, two ends of each pull rod are respectively in threaded connection with corresponding positions of the pull plate and the base.

The utility model has the advantages that: the operation is simple, the stress is even, the pulling force is large, the application range is wide, the efficiency is high, the practicability is high, and the device can be applied to the dismounting and replacing of various firmware.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

As shown in fig. 1-3, a puller comprises a pulling plate 1, a base 2 and two pulling rods 3. The pulling plate 1 and the base 2 are oppositely arranged. The two pull rods 3 are respectively located at the upper part and the lower part between the pull plate 1 and the base 2, and two ends of each pull rod 3 are respectively connected with the corresponding positions of the pull plate 1 and the base 2, specifically: two ends of each pull rod 3 are respectively in threaded connection with corresponding positions of the pull plate 1 and the base 2. And a notch 4 matched with a shaft of a part to be disassembled is arranged on the pulling plate 1.

The base 2 is a square bar structure formed by welding two steel grooves. The pull plate 1 is circular, the notch comprises a square part and a semicircular part, the width of the square part is equal to the diameter of the semicircular part, and the width of the square part is matched with the diameter of the semicircular part and the radial size of a shaft of a part to be disassembled. One end of the square part is positioned in the middle of the outer edge of one side of the pulling plate 1, and the other end of the square part extends to the position of the circle center of the pulling plate 1. The semicircular part is communicated with the other end of the square part.

As shown in fig. 4, when the bearing 5 and the shaft 6 are disassembled, the shaft 6 is placed in the notch 4, the bearing 5 is ensured to be attached to one side of the pulling plate 1 close to the base 2, the end part of the shaft 6 in the bearing 5 is pushed by the jack 7, and finally the shaft 6 and the bearing 5 are separated to complete the disassembly. The puller is simple to operate, uniform in stress, large in pulling force, wide in application range, high-efficient and practical.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
