Description

Frock is dismantled to engine belt pulley

Technical Field

The utility model relates to an engine maintenance tool, in particular to an engine belt pulley disassembly tool.

Background

At present, when an engine is maintained after running or a related vulnerable part belt is replaced, an engine belt pulley needs to be disassembled so as to complete quick maintenance and treatment. For disassembly of the engine pulley, the driving operation mode is to knock the pulley by using a hammer so that the pulley is separated from the wheel shaft, but the pulley is easily damaged by the method, and the method is eliminated. At present, the belt pulley is disassembled through a special disassembly tool, for example, the patent number is: CN201220604173.0 engine pulley extracting tool, this extracting tool is with the ring flange through the screw connection of bolt with the belt pulley for flange and belt pulley become an organic whole, then utilize the screw rod anti-top wheel axle again, make the ring flange drop from the wheel axle together with the belt pulley, realize the dismantlement of engine pulley.

However, in the existing disassembling tool, the position of the hole on the flange plate relative to the screw rod is fixed, and the position of the bolt can not be adjusted according to the diameter of the belt pulley, so that only one belt pulley can be disassembled to correspond to one tool, and the problem of high cost is caused.

Disclosure of Invention

The technical problem to be solved by the utility model is to provide the disassembly tool for the engine belt pulley, which can quickly disassemble the engine belt pulleys with different diameters and is more convenient to use.

The technical scheme of the utility model is as follows: the utility model provides an engine belt pulley dismantles frock, includes the ring flange, set up a plurality of locating holes of evenly arranging on the ring flange, the locating hole be along the radial long waist shape hole that extends of ring flange, two of them the locating hole on the activity peg graft have fastening bolt, the ring flange center peg graft and have the screw rod, ring flange center still be fixed with the screw thread seat, screw rod and screw thread seat threaded connection.

As a further improvement, one end of the screw is provided with a hexagon head.

Further, rubber pads are arranged at the end part of the flange plate and the other end of the screw rod.

Further, a thread groove is further formed in one side of the flange plate, and the thread specification of the fastening bolt is the same as that of the thread groove.

Further, the hexagonal head and the screw are of an integrated structure.

Further, the flange plate and the thread seat are of an integrated structure.

Advantageous effects

Compared with the prior art, the utility model has the following advantages:

1. according to the disassembly tool for the engine belt pulley, the plurality of long kidney-shaped positioning holes are formed in the flange plate, when the disassembly tool is used, the flange plate is attached to the end portion of the belt pulley, then the flange plate is integrated with the belt pulley by penetrating through the positioning holes through the fastening bolts and connecting with screw holes of the belt pulley, and then the belt pulley is fixed by rotating the screw reverse-jacking belt pulley shaft, so that the disassembly of the engine belt pulley is completed rapidly.

2. According to the disassembly tool for the engine belt pulley, the screw groove is formed in the flange plate, and when the tool is not used, the fastening bolt can be connected in the screw groove in a screw mode, so that the disassembly tool is prevented from being lost.

Drawings

FIG. 1 is a schematic diagram of a front view of the present utility model;

fig. 2 is a schematic side view of the present utility model.

Wherein: 1-flange plate, 2-locating hole, 3-screw seat, 4-fastening bolt, 5-hexagon head, 6-screw groove, 7-screw rod, 8-rubber pad.

Detailed Description

The utility model will be further described with reference to specific embodiments in the drawings.

Referring to fig. 1-2, the disassembly tool for the engine belt pulley comprises a flange plate 1, wherein the flange plate 1 is a disc, a plurality of uniformly arranged positioning holes 2 are formed in the flange plate 1, the positioning holes 2 are long kidney-shaped holes extending along the radial direction of the flange plate 1, two positioning holes 2 are movably inserted with fastening bolts 4, the center of the flange plate 1 is inserted with a screw rod 7, the center of the flange plate 1 is also fixedly provided with a thread seat 3, and the screw rod 7 is in threaded connection with the thread seat 3.

According to the disassembly tool for the engine belt pulley, the plurality of long kidney-shaped positioning holes 2 are formed in the flange plate 1, when the disassembly tool is used, the flange plate 1 is attached to the end part of the belt pulley, then the fastening bolt 4 penetrates through the positioning holes 2 and is connected with screw holes of the belt pulley, so that the flange plate 1 and the belt pulley are integrated, then the screw rod 7 is rotated to reversely push the belt pulley shaft to fix the belt pulley out, and therefore disassembly of the engine belt pulley is completed rapidly.
