Description

Technical Field

[0001] This utility model relates to the field of machining, and in particular, to a special machining equipment for high-alignment pump housings. Background Technology

[0002] like Figure 1 and Figure 2 The diagram shown is a structural schematic of the pump housing. Currently, the shaft hole on the pump housing needs to be enlarged. During enlargement, the axis of the shaft hole must be parallel to the axis of the cutting tool.

[0003] Because the pump housing is quite large, the lathe's three-jaw chuck cannot hold it. Therefore, the current method is to first weld an extension rod to the outer wall of the pump housing, parallel to the axis of the shaft hole. Then, the three-jaw chuck is used to clamp and fix the extension rod. After the hole is enlarged, the extension rod is then sawn off.

[0004] Therefore, the process is rather complicated, involves a lot of equipment, and has low production efficiency; and if the connection between the extension rod and the outer wall of the pump box is not strong, safety accidents are likely to occur. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a special processing equipment for high-alignment pump housings, so as to improve production efficiency and safety.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a special processing equipment for high-alignment of pump housing, including a support plate fixed on a three-jaw chuck, an elevation plate connected to the support plate, two positioning shafts connected to the elevation plate, the axes of the two positioning shafts being arranged in parallel, a positioning ring connected to the elevation plate, the positioning ring being used to embed into the side hole of the pump housing, a pressure plate provided on the positioning shaft, a connecting hole provided on the pressure plate, the positioning shaft passing through the connecting hole and being threadedly connected to a locking sleeve, the pressure plate being pressed against the inner wall of the pump housing by the pressure of the locking sleeve, and a positioning component provided on the pressure plate;

[0007] Rotate the pump housing along the axis of the side hole and then position the pump housing using the positioning assembly, so that the axis of the shaft hole of the pump housing is parallel to the axis of the cutting tool.

[0008] To achieve the above technical solution, the pump housing is placed on the riser plate, with the side hole on the pump housing fitted onto the outside of the positioning ring. Then, the pressure plate is placed inside the pump housing, with the connecting hole fitted onto the positioning shaft, so that the pressure plate abuts against the inner wall of the pump housing. The pump housing is then rotated along the axis of the side hole, and positioned using the positioning assembly. At this point, the axis of the pump housing's shaft hole is parallel to the axis of the cutting tool. Finally, a locking sleeve is threaded onto the positioning shaft, causing the locking sleeve to abut against the pressure plate, and the pressure plate to abut against the inner wall of the pump housing. The resulting friction secures the pump housing. This method is simple to install and greatly improves production efficiency and safety. Finally, with the three-jaw chuck rotating, the cutting tool is moved towards the three-jaw chuck to achieve the hole enlargement operation.

[0009] As a preferred embodiment of this utility model, the positioning component includes a positioning recess, a mounting recess, an anti-detachment ring, an elastic element, and a T-shaped rod. The positioning recess is opened on the inner wall of the pump housing and near the side hole. The mounting recess is opened on the side of the pressure plate facing the positioning recess. The elastic element is placed in the mounting recess. The T-shaped rod is slidably connected in the mounting recess. The anti-detachment ring is threadedly connected to the mounting recess and is used to abut against the T-shaped rod. The T-shaped rod abuts against the inner wall of the positioning recess due to the elastic force of the elastic element.

[0010] To achieve the above technical solution, a pressure plate is placed inside the pump housing, and a connecting hole is fitted onto the outside of the positioning shaft. Gravity causes the pressure plate to abut against the inner wall of the pump housing. At this time, the pressure between the pressure plate and the inner wall of the pump housing causes the T-shaped rod to be fully placed inside the mounting recess. Then, the pump housing is rotated along the axis of the side hole. When the positioning recess aligns with the T-shaped rod, the elastic force of the elastic element causes the T-shaped rod to extend out of the mounting recess and strike the inner wall of the positioning recess. The resulting sound reminds the worker that the axis of the shaft hole on the pump housing is now parallel to the axis of the cutting tool. The operation is simple. The positioning recess is formed simultaneously when the pump housing is cast.

[0011] As a preferred embodiment of this utility model, a protruding post is fixedly connected to the side of the heightening plate opposite to the positioning ring, a rotating hole for the protruding post to pass through is provided on the support plate, a first limiting hole is provided on the support plate, a second limiting hole corresponding to the first limiting hole is provided on the heightening plate, and the positioning shaft passes through the second limiting hole and is threaded to the first limiting hole.

[0012] To achieve the above technical solution, the protruding post is placed in the rotating hole, and the positioning shaft is threaded onto the first limiting hole after passing through the second limiting hole. This enables the connection between the raising plate and the support plate, making it easier to replace and install the raising plate.

[0013] As a preferred embodiment of this utility model, the support plate includes a vertical plate, a horizontal plate, and a reinforcing plate. The vertical plate is fixedly connected to a three-jaw chuck, the horizontal plate is vertically fixed to the vertical plate and is used to support the pump housing, one side of the reinforcing plate is fixedly connected to the vertical plate, and the other side of the reinforcing plate is fixedly connected to the horizontal plate.

[0014] To achieve the above technical solution, the vertical plate is fixedly connected to the three-jaw chuck, and the horizontal plate is vertically fixed to the vertical plate. The reinforcing plate can improve the connection stability between the vertical plate and the horizontal plate, so that the support plate can stably support the pump box.

[0015] As a preferred embodiment of this utility model, a connecting groove is provided on the inner wall of the connecting hole, and a spring piece is provided in the connecting groove. The spring piece is bent into a U-shape and its two ends are fixed to the inner wall of the connecting groove. The middle part of the spring piece extends out from the connecting groove and is used to abut against the outer wall of the positioning shaft.

[0016] To achieve the above technical solution, after placing the pressure plate inside the pump housing, the positioning shaft passes through the connecting hole and abuts against the outer wall of the positioning shaft through the middle of the spring piece, increasing the friction and making the connection between the pressure plate and the positioning shaft more stable. This makes the pressure plate abut against the inner wall of the pump housing more stable, thereby making the pump housing more stable on the support plate and improving safety.

[0017] As a preferred embodiment of this utility model, an anti-slip plate is fixedly connected to the middle of the spring piece, and the anti-slip plate abuts against the outer wall of the positioning shaft.

[0018] To achieve the above technical solution, the anti-slip plate presses against the outer wall of the positioning shaft through the elastic force of the spring plate, further increasing the friction force, so that the pump box body is more stable on the support plate and further improving safety.

[0019] As a preferred embodiment of this utility model, the anti-slip plate has an anti-slip groove on the side facing the positioning shaft.

[0020] The above technical solution further enhances the friction between the anti-slip plate and the positioning shaft. Attached Figure Description

[0029] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered.

[0030] A specialized machining equipment for high-alignment pump housings includes a support plate 2 fixed to a three-jaw chuck. The support plate 2 comprises a vertical plate 21, a horizontal plate 22, and a reinforcing plate 23. The vertical plate 21 is fixed to the three-jaw chuck with screws, and the horizontal plate 22 is vertically fixed to the vertical plate 21 and serves to support the pump housing 1. One side of the reinforcing plate 23 is fixedly connected to the vertical plate 21, and the other side of the reinforcing plate 23 is fixedly connected to the horizontal plate 22. The reinforcing plate 23 has a triangular cross-section.

[0031] A riser plate 3 is connected to the support plate 2. A protruding post 31 is fixedly connected to the side of the riser plate 3 facing the support plate 2, and the protruding post 31 is coaxially arranged with the riser plate 3. A rotating hole 32 is provided on the support plate 2 for the protruding post 31 to pass through. Two first limiting holes 33 are provided on the support plate 2, and the two first limiting holes 33 are evenly distributed along the axis of the rotating hole 32. The first limiting holes 33 do not penetrate the support plate 2.

[0032] A second limiting hole 34 is provided on the raising plate 3 to correspond to the first limiting hole 33. The diameter of the first limiting hole 33 is equal to the diameter of the second limiting hole 34. The positioning shaft 4 passes through the second limiting hole 34 and is threaded to the first limiting hole 33, so that the first limiting hole 33 and the second limiting hole 34 are coaxially arranged.

[0033] A positioning ring 5 is integrally connected to the riser plate 3, and the positioning ring 5 is coaxially arranged with the riser plate 3. The positioning ring 5 is used to embed into the side hole 12 of the pump housing 1, and the positioning shaft 4 passes through the interior of the pump housing 1.

[0034] A pressure plate 6 is provided on the positioning shaft 4, and a connecting hole 61 is provided on the pressure plate 6. The positioning shaft 4 passes through the connecting hole 61 and is threadedly connected to a locking sleeve 41. A positioning assembly 7 is provided on the pressure plate 6. The pressure plate 6 is placed inside the pump housing 1 and presses against the inner wall of the pump housing 1. The pump housing 1 is rotated along the axis of the side hole 12. The positioning assembly 7 positions the pump housing 1 so that the axis of the shaft hole 11 of the pump housing 1 is parallel to the axis of the cutting tool.

[0035] The positioning assembly 7 includes a positioning recess 71, a mounting recess 72, an anti-detachment ring 73, an elastic element 74, and a T-shaped rod 75. The positioning recess 71 is formed on the inner wall of the pump housing 1, near the side hole 12 of the pump housing 1. To improve production efficiency, the positioning recess 71 is formed along with the pump housing 1 during casting. The mounting recess 72 is formed on the side of the pressure plate 6 facing the positioning recess 71, and the inner wall of the mounting recess 72 is threaded. The elastic element 74 is placed inside the mounting recess 72, and the T-shaped rod 75 is slidably connected to the mounting recess 72. The anti-detachment ring 73 is threaded onto the mounting recess 72 and abuts against the T-shaped rod 75 to prevent the T-shaped rod 75 from detaching from the mounting recess 72. The T-shaped rod 75 abuts against the inner wall of the positioning recess 71 due to the elastic force of the elastic element 74. The end of the T-shaped rod 75 is hemispherical.

[0036] When the pressure plate 6 presses against the inner wall of the pump housing 1, the pressure from the pressure plate 6 causes the T-shaped rod 75 to be fully positioned within the mounting recess 72. Rotating the pump housing 1 along the axis of the side hole 12, when the positioning recess 71 aligns with the T-shaped rod 75, the elastic force of the elastic element 74 causes the end of the T-shaped rod 75 to engage in the positioning recess 71, producing an audible alert to indicate to the worker that the shaft hole 11 on the pump housing 1 is now parallel to the cutting tool axis. The elastic element 74 is a spring.

[0037] Then, the locking sleeve 41 is threaded onto the positioning shaft 4. The pressure plate 6 is pressed against the inner wall of the pump box 1 by the pressure of the locking sleeve 41, thereby fixing the pump box 1 onto the support plate 2. The operation is simple.

[0038] To make the pump housing 1 more stable on the support plate 2, a connecting groove 8 is provided on the inner wall of the connecting hole 61. A spring piece 81 made of copper sheet is provided in the connecting groove 8. The spring piece 81 is bent into a U shape and its two ends are welded to the inner wall of the connecting groove 8. The middle part of the spring piece 81 extends out from the connecting groove 8.

[0039] A rubber anti-slip piece 82 is fixedly connected to the middle of the spring piece 81 by adhesive, and the anti-slip piece 82 abuts against the outer wall of the positioning shaft 4. An anti-slip groove 83 is provided on the side of the anti-slip piece 82 facing the positioning shaft 4.

[0040] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
