Description

Technical Field

[0001] This utility model relates to the field of pump body processing, and in particular to a support device for pump body processing. Background Technology

[0002] A pump is a machine that transports or pressurizes fluids. It transfers the mechanical energy of a prime mover or other external energy to a liquid, increasing the liquid's energy. Pumps are mainly used to transport liquids such as water, oil, acid and alkali solutions, emulsions, suspensions, and liquid metals. They can also transport liquid-gas mixtures and liquids containing suspended solids.

[0003] Whether it's airplanes, rockets, tanks, submarines, drilling, mining, trains, ships, or even daily life, pumps are needed everywhere, and pumps are running everywhere, such as plunger pumps, slurry pumps, split-case pumps, water pumps, and so on.

[0004] In the current manufacturing process of pumps, especially large pumps, the pump body is typically divided into two separate sections. Each section is then machined separately, and finally joined together using bolts or other fasteners to form a complete pump body. The existing machining method involves first casting to create the outer contour of each section, followed by machining the inner circle and outer wall of the sections using turning, drilling, and other techniques.

[0005] When machining the cast pump body, it is necessary to first clamp and fix the parts using tooling before turning, drilling, and other machining operations can be performed. However, the clamping positions of existing tooling are mostly fixed. The surface of the cast pump body is relatively rough, and it is inevitable that there will be some defects such as protrusions and bumps. If there are protrusions or other defects at the clamping points of the pump body, continuing to clamp it with existing tooling will cause the pump body to tilt after clamping, which will affect subsequent machining. Therefore, it is necessary to clean and machine the protrusions and other defective areas at the clamping points before clamping, which is very troublesome. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a support device for pump body processing that facilitates clamping of the pump body after casting.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is: a support device for pump body processing, the innovation of which is: including A supporting base; A support assembly mounted on a support base includes several columns distributed on the support base. The upper part of each column is L-shaped, and the horizontal surface of the upper part of the column is defined as the support surface, and the vertical surface of the upper part of the column is defined as the clamping surface. Several vertically distributed support holes are opened on the support surface of the column. The support holes are threaded blind holes, and each support hole is arranged in a rectangular array. A vertically arranged support block is threadedly connected to each support hole. Several horizontally penetrating clamping holes are opened on the clamping surface of the column and arranged in a straight line. The clamping holes are threaded through holes, and a clamping block is threadedly connected to each clamping hole. A clamping assembly is installed on a support base. The clamping assembly includes several clamping seats distributed on the support base. A vertically arranged clamping bolt is threaded to the clamping seat. A clamping plate is also fitted on the outer wall of the clamping bolt. A through hole is opened on the clamping plate to allow the clamping bolt to pass through. A clamping nut that is threaded to the clamping bolt is also provided above the clamping plate.

[0008] Furthermore, the ends of both the support block and the clamping block are arc-shaped.

[0009] Furthermore, the fit between the clamping plate and the clamping bolt is as follows: the through hole on the clamping plate is an oblong hole, and a tightening bolt is threadedly connected to one side of the clamping plate. The tightening bolt passes horizontally through the clamping plate from the outside to the inside and extends into the through hole of the clamping plate, and abuts against the side wall of the clamping bolt.

[0010] The advantages of this utility model are as follows: The support device in this utility model uses the cooperation of support blocks and clamping blocks to clamp and fix the pump body. The support blocks and clamping blocks are fixed by the cooperation of support holes arranged in a rectangular array and clamping blocks arranged in a straight line. The corresponding holes can be selected for the installation of support blocks or clamping blocks according to the requirements of different clamping positions, thereby avoiding defects such as protrusions on the outer wall of the pump body and ensuring that the pump body can be level after clamping. There is no need to deal with defects in advance, which is very convenient.

[0011] Both the support block and the clamping block have an arc-shaped design at their ends, which ensures point-to-surface contact when supporting the outer wall of the pump body or clamping the pump body at its ends. This better supports or clamps the pump body and avoids tilting caused by surface-to-surface contact.

[0012] The fit between the clamping plate and the clamping bolt is achieved by designing the through hole on the clamping plate as an oblong hole, which allows the position of the clamping plate to be adjusted horizontally according to different clamping positions as needed. The design of the tightening bolt is to provide a one-way fixation for the relative position between the clamping plate and the clamping bolt. Attached Figure Description

[0015] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0016] like Figure 1 , Figure 2 The illustrated pump body machining support device includes A support base 1, which is rectangular in shape.

[0017] A support assembly is installed on the support base 1. The support assembly includes several columns 2 distributed on the support base 1. The bottom end of the column 2 is fixed to the support base 1 by bolts. The upper part of the column 2 is L-shaped. The horizontal surface of the upper part of the column 2 is defined as the support surface, and the vertical surface of the upper part of the column 2 is defined as the clamping surface. Several vertically distributed support holes 21 are opened on the support surface of the column 2. The support holes 21 are threaded blind holes, and the support holes 21 are arranged in a rectangular array. A vertically arranged support block 24 is threaded into the support hole 21. Several horizontally penetrating clamping holes 22 are opened on the clamping surface of the column 2 and are arranged in a straight line. The clamping holes 22 are threaded through holes, and a clamping block 23 is threaded into the clamping hole 22.

[0018] Both the support block 24 and the clamping block 23 have arc-shaped ends. The arc-shaped design of the ends of the support block 24 and the clamping block 23 ensures point-to-surface contact when supporting the outer wall of the pump body 4 or clamping the ends of the pump body 4, thus better supporting or clamping the pump body 4 and avoiding tilting of the pump body 4 due to surface-to-surface contact.

[0019] A clamping assembly is provided on the support base 1. The clamping assembly includes several clamping seats 3 distributed on the support base 1. A vertically arranged clamping bolt 31 is threadedly connected to the clamping seat 3. A clamping plate 32 is also fitted on the outer wall of the clamping bolt 31. A through hole is opened on the clamping plate 32 to allow the clamping bolt 31 to pass through. A clamping nut 33 that is threadedly engaged with the clamping bolt 31 is also provided above the clamping plate 32.

[0020] The fit between the clamping plate 32 and the clamping bolt 31 is as follows: the through hole on the clamping plate 32 is an oblong hole, and a tightening bolt 34 is threadedly connected to one side of the clamping plate 32. The tightening bolt 34 passes horizontally through the clamping plate 32 from the outside to the inside and extends into the through hole of the clamping plate 32, with the end of the tightening bolt 34 abutting against the side wall of the clamping bolt 31. The fit between the clamping plate 32 and the clamping bolt 31, by designing the through hole on the clamping plate 32 as an oblong hole, allows the position of the clamping plate 32 to be adjusted horizontally according to different clamping positions. The design of the tightening bolt 34 is to provide a unidirectional fixation of the relative position between the clamping plate 32 and the clamping bolt 31.

[0021] Working principle: When processing the pump body 4, firstly, the pump body 4 is placed on each column 2. Then, the support points of the pump body 4 and the columns 2 are observed to see if there are any defects such as protrusions at the support points and clamping points of the pump body 4. Then, according to the observation results, the required support holes 21 and clamping holes 22 are selected, and the support blocks 24 and clamping blocks 23 are threaded into the corresponding support holes 21 and clamping holes 22 respectively to support and clamp the pump body 4. Then, the pressure plate 32 is pressed on the upper end face of the pump body 4, and the pressure nut 33 is tightened so that the pressure nut 33 is pressed tightly on the upper end face of the pressure plate 32. Then, the top bolt 34 is pressed against the side wall of the pressure bolt 31 to achieve the pressing and fixing of the pump body 4. Finally, the pump body 4 is machined by a machining center.
