Description

Technical Field

[0001] The invention relates to the field of mechanical processing equipment, in particular to a disassembly tool for a gear pump. Background Art

[0002] The gear metering pump is a gear pump in the form of a gear and is one of the key components on the spinning line. Its purpose is to accurately measure, evenly and continuously deliver the spinning melt or solution to the spinneret at a certain pressure to ensure that the melt or solution can overcome the resistance of the spinning assembly and spray out from the capillary pores of the spinneret to form fibers with uniform linear density. The metering pump needs to be disassembled and cleaned after damage or shutdown.

[0003] When the pump body is disassembled, there is a lot of residual material in the pump, which solidifies and crystallizes inside the pump body, causing the various parts of the pump body to stick to each other. After the pump body screws are removed, although there is an opening groove, due to limited space and limited force acting on the opening, it is sometimes still difficult to disassemble and separate the panels.

[0004] In order to solve the above technical problems, the applicant has conducted many studies and finally developed an auxiliary tool that can quickly disassemble the pump body. In actual application, it makes the disassembly of the pump body more convenient and has won unanimous praise from customers. Utility Model Content

[0005] In order to solve the technical problems in the background technology, the utility model provides a disassembly tool for a gear pump, and the technical solution adopted is as follows:

[0006] A gear pump disassembly tool, characterized in that it includes a pressure plate, which is a fixed component of the utility model. The pressure plate is used to contact the gear pump. The lower bottom surface of the pressure plate is a horizontal structure, which makes it easier to fit the surface of the pump body, thereby making it easier to disassemble the pump body. The shape of the pressure plate is a rectangular parallelepiped, a cylinder, or a polygonal structure.

[0007] A slide groove is arranged in the pressure plate, and the slide groove is used for the pull plate to slide left and right. The pull plates are symmetrically arranged in the slide groove. The pull plates are made of metal material. The pull plates move left and right in the slide groove to adjust the distance to adapt to the width of the pump body.

[0008] The lower part of the pull plate is bent inwardly, and the bent part is used to be fixed with the gear pump. A plurality of openings are arranged on the pump body of the gear pump, and the openings match with the bent parts to form a fixation, and the bent parts are inserted into the openings to form a fixation.

[0009] An opening component is provided in the middle of the pressure plate, and the opening component includes an opening bolt. The pressure plate is provided with an opening thread. The opening bolt matches the opening thread and moves in the opening thread to form an opening action. This design adopts a lifting tooling. The leftmost end of the design is the rear plate of the pump body, and the rear plate has an opening groove. On the right are two pull plates, one end of the pull plate is inserted into the opening mouth, and the right part of the pull plate is the pressure plate. The pull plate can be inserted into the slide groove from the side, and the left end is stuck in the opening groove of the rear plate. The right part of the pressure plate is the opening bolt, which is screwed into the threaded hole of the pressure plate, and its left part is against the tail of the driving shaft of the pump body. The rear plate is separated from the middle plate through the reaction force of the shaft. The pressure plate, pull plate and opening bolt are all made of metal.

[0010] In summary, the present invention has the following beneficial effects: through the structural transformation of the utility model, the whole work is more flexible and convenient. The design adopts the form of lifting. Through the opening bolt at the rightmost end, a large force acts on the opening groove of the rear plate. The two symmetrical pulling blocks make the rear plate evenly stressed, so that the rear plate is separated from the middle plate. In actual application, the disassembly speed is significantly improved. The use of this tooling can make the various plates of the pump body easier to disassemble, which is suitable for comprehensive promotion and application. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0017] Example 1

[0018] like Figure 1-Figure 4 Shown

[0019] A gear pump disassembly tool, characterized in that it comprises a pressing plate 3, the pressing plate 3 is in the shape of a rectangular parallelepiped structure, and the pressing plate 3 is used to contact the gear pump;

[0020] A slide groove 5 is provided in the pressing plate 3, and a pull plate 1 is symmetrically provided in the slide groove 5. The pull plate 1 moves left and right in the slide groove 5 for adjustment;

[0021] The lower part of the pull plate 1 is bent inward, and the bent part is used to fix with the gear pump;

[0022] An opening component is provided in the middle of the pressing plate 3.

[0023] The opening assembly includes an opening bolt 2, and a pressure plate 3 is provided with an opening thread;
