Description

An iron hand puller

technical field

The utility model relates to a dismantling tool for a shaft sleeve, a bearing and a sheave, in particular to an iron hand puller.

Background technique

The work of disassembling bearings, bushings, sheaves and other workpieces often occurs. The disassembly method commonly used in the industry is to use a three-jaw puller for disassembly. The three-jaw puller has three pulling points, and it is easy to slip when one person operates alone , there is a potential safety hazard for the operator, and it is time-consuming and labor-intensive, and the disassembly quality cannot be guaranteed.

Contents of the invention

The utility model is to make up for the shortcomings of the three-jaw puller when it is disassembled, and proposes an iron hand puller, in order to disassemble various accessories conveniently and flexibly, and is convenient to carry and has high safety performance.

The utility model adopts following technical scheme in order to solve technical problems:

The structural features of an iron hand tensioner of the utility model include: fastening bolts, adjusting screw rods, movable supports, fixed steel plates, connecting pulleys, handles and locks;

The main frame is composed of the fixed steel plate, the movable support and the adjusting screws on both sides;

One end of the movable support and one end of the connecting lever are hinged structures, and the other end of the movable support is provided with the lock; in the middle of the movable support, a "U" groove is provided for for placing the workpiece; and the "U" groove is closed by the connecting pull and the lock;

The fastening bolt passes through the fixed steel plate and abuts against the top of the workpiece; a circular ring is arranged on the top of the fastening bolt, and the handle is set in the circular ring;

The rotation of the handle drives the fastening bolt to form a disassembly structure for the workpiece in the movable support.

The structural features of the iron hand puller described in the utility model also lie in that: the lock is a rotatable structure on the movable support; the lock is composed of a bolt and a collar; An opening is provided at one end, and the lock catch is inserted into the opening through its bolt, and the position is limited by a collar, thereby forming a fixed structure of the connecting pull and the movable support.

Compared with the existing technology, the beneficial effects of the utility model are reflected in:

The utility model has the advantages of simple structure, convenient operation and flexibility, and is suitable for the disassembly of various shaft sleeves, bearings, sheaves and other accessories, and the operation can be completed by one person alone, which saves time and effort, is safe to operate, and effectively improves the work efficiency .

detailed description

In this embodiment, as shown in Figure 1 , an iron hand puller includes: fastening bolt 1, adjusting screw rod 2, movable support 3, fixed steel plate 4, connecting lever 5, handle 6 and lock 7;

The main frame is composed of the fixed steel plate 4, the movable support 3 and the adjustment screw 2 on both sides; the adjustment screw 2 can be used to adjust the distance between the fixed steel plate 4 and the movable support 3 under the cooperation of the nut, so that it is suitable for different sizes Bearings, bushings, grooved wheels and other workpieces 8;

One end of the movable support 3 and one end of the connecting lever 5 are hinged structures, and the other end of the movable support 3 is provided with a lock 7; in the middle of the movable support 3, a "U"-shaped groove is provided for placing the workpiece 8; And the "U"-shaped groove is closed by the connecting lever 5 and the lock 7; thereby preventing the sliding of the disassembled workpiece;

The fastening bolt 1 runs through the fixed steel plate 4 and is against the top of the workpiece 8; a ring is arranged on the top of the fastening bolt 1, and the handle 6 is set in the ring;

Utilize the principle of leverage to rotate the handle 6 and drive the fastening bolt 1 to form a dismounting structure for the workpiece 8 in the movable support 3 .

In specific implementation, as shown in Figure 2, the lock catch 7 is a rotatable structure on the movable support 3; The bolts are embedded in the openings, and the collars are used to limit the position, so as to form a fixed structure between the connecting plate 5 and the movable support 3 .
