Description

a removal tool

technical field

The utility model relates to a dismantling tool, in particular to a tool for dismantling the short shaft of a metering pump drive shaft.

Background technique

Metering pump is a special positive displacement pump that can meet the needs of various strict technological processes. The flow rate can be adjusted steplessly within the range of 0-100%. It is used to transport liquids (especially corrosive liquids). The metering pump belongs to the reciprocating positive displacement pump, which is used for precise metering. Usually, the stability accuracy of the metering pump is required to be no more than ±1%. With the continuous development of modern industry towards automatic operation and long-distance automatic control, the advantages of metering pumps, which are highly compatible and adaptable to a wide range of media (liquids), are particularly prominent.

The equipment used in the spinning workshop of the chemical fiber industry is Barmag equipment in Germany. The short shaft of the Barmag metering pump drive shaft has two sizes, one is suitable for single-key metering pumps, and the other is suitable for double-key metering pumps. The quality of the metering pump is not as good as that of the double-key metering pump. In order to save costs, it is necessary to replace the single-key metering pump with a double-key metering pump. At the same time, the short shaft of the metering pump drive shaft must also be replaced. A lot of pressure. At present, hammers and bench vises are used to disassemble the drive shaft, and the short shaft of the drive shaft is clamped with a bench vise and hit with a hammer. This method is a waste of time and manpower, and has certain potential safety hazards. Cause equipment damage, greatly shorten the service life of equipment, affect production efficiency and product quality.

Contents of the invention

The purpose of the utility model is a dismantling tool designed for convenient dismantling of the short shaft of the metering pump drive shaft.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a disassembly tool, including: a support base, a thrust rod, a support frame, a tension rod, a tension sleeve, and a balance bar. On the drive shaft of the pump, the thrust rod is connected with the support frame, the tension rod is located in the tension sleeve, and connected by the balance rod to form a whole, insert the thrust rod into the round hole of the support base, lock the tension sleeve, and the balance rod withstands the metering pump There is a groove at the top of the short shaft of the transmission shaft, and the short shaft of the transmission shaft of the metering pump can be disassembled by rotating the thrust rod.

In the above technical solution, there are bottom-through and bottom-impermeable holes on the support base, the purpose of which is to coincide with the thrust rod so that the object can be pushed out.

In the above technical solution, the thrust rod is a threaded rod, which can be propelled by rotation or external force.

In the above technical solution, the tension rod is a semi-threaded rod connected with the tension sleeve and the support frame.

In the above technical solution, the inside of the tension sleeve is in the shape of teeth for better locking the drive shaft of the metering pump.

The dismantling tool obtained by the utility model has a simple structure and can more conveniently disassemble the short shaft of the metering pump transmission shaft, which reduces labor force, saves time, improves work efficiency, eliminates potential safety hazards and prolongs the service life of the equipment.

Detailed ways

Below in conjunction with Fig. 1 the utility model is further described.

As shown in Figure 1, the removal tool described in this embodiment includes a support base 1, a thrust rod 2, a support frame 3, a tension rod 4, a tension sleeve 5, and a balance rod 6, and its main technical features are: 1 set of support base On the drive shaft of the metering pump, the thrust rod 2 is connected to the support frame 3, the tension rod 4 is located in the tension sleeve 5, and is connected through the balance rod 6 to form a whole, insert the thrust rod 2 into the round hole of the support base 1, and lock it The tension sleeve 5 and the balance rod 6 withstand the top groove of the short shaft of the metering pump drive shaft, and the short shaft of the metering pump drive shaft can be disassembled by rotating the thrust rod 2 . Bottom-through holes and bottom-impermeable holes are arranged on the support base 1, and the purpose is to coincide with the thrust rod 2 so as to push the object out. The thrust rod 2 is a threaded rod, which can be propelled by rotation or external force. The tension rod 4 is a semi-threaded rod connected with the tension sleeve 5 and the support frame 3 . The inside of the tension sleeve 5 is a tooth shape, and the purpose is to better lock the metering pump drive shaft. The dismantling tool obtained by the utility model has a simple structure, and can more conveniently disassemble the short shaft of the metering pump transmission shaft, reduces labor force, saves time, improves work efficiency, eliminates potential safety hazards and prolongs the service life of the equipment.

Those skilled in the technical field to which the utility model belongs can make various modifications and supplements to the examples, but will not exceed the scope defined in the claims of the utility model.
