[0038] In this embodiment, in order to solve the problem that the corresponding pump casings on both sides cannot be accurately clamped and positioned during drilling, and the hole positions of the pump casings on both sides are prone to dimensional deviation, a pump body processing tool is designed. When the pump casing needs to be processed, the sliding column 2 is first raised to install the pump casing on the pump body processing tool, and the pump casing is positioned according to the positioning hole 101 and the positioning surface 102. Then, the rotating column 3 is rotated to drive the clamping plate 4 to rotate to clamp the pump casing. After clamping, holes are drilled through the positioning holes to avoid inaccurate hole positions.

[0039] The working principle of the utility model is that when the pump casing needs to be processed, the operator installs one side of the pump casing on the tooling for pump body processing. The installation process is to first slide out the sliding column 2, place the pump casing on the tooling for pump body processing, retract the sliding column 2, rotate the rotating column 3, and drive the clamping plate 4 to rotate, thereby clamping the pump casing. After clamping, drill holes through the positioning holes to avoid inaccurate hole positions.

[0040] Furthermore, it also includes a first connecting rod 5, a plurality of first connecting rods 5, the first connecting rods 5 are arranged along the central circumference of the base plate 1, and one end of the first connecting rod 5 is rotatably set on the base plate 1; a plurality of second connecting rods 6, the second connecting rods 6 are used in pairs with the first connecting rods 5, one end of the second connecting rod 6 is rotatably set on the other end of the first connecting rod 5, and the other end of the second connecting rod 6 is rotatably set on the sliding column 2.

[0041] In this embodiment, when the sliding column 2 slides, it will drive the first connecting rod 5 and the second connecting rod 6 to swing. When the sliding column 2 slides out, the angle between the first connecting rod 5 and the second connecting rod 6 is the largest, allowing the pump casing to pass through. When the sliding column 2 retracts, the angle between the first connecting rod 5 and the second connecting rod 6 is the smallest, which can support the pump casing internally and accurately position the pump casing.

[0042] Furthermore, it also includes a handle 7, which is fixedly arranged at one end of the rotating column 3; the first follower rod 8 has a plurality of first protrusions 801, and the first protrusions 801 are used in pairs with the clamping plate 4. The first follower rod 8 is fixedly arranged at one end of the rotating column 3 close to the handle 7, and the rotating column 3 is in contact with the clamping plate 4 through the first protrusions 801, so as to drive the clamping plate 4 to rotate.

[0043] In this embodiment, the handle 7 rotates to drive the rotating column 3 to rotate, and the rotating column 3 drives the first follower rod 8 to rotate, and the first protrusion 801 abuts against the clamping plate 4, thereby driving the clamping plate 4 to rotate, thereby pressing the pump housing onto the base plate 1.

[0044] Furthermore, the upper surface of the sliding column 2 has a first groove 201 , and also includes: one end of a first elastic member 9 is fixedly disposed in the first groove 201 , and the other end is in contact with the clamping plate 4 , so as to provide elastic force for the clamping plate 4 to return to its original position after rotation.

[0045] In this embodiment, the sliding column 2 has a first groove 201 , an elastic member is disposed in the first groove 201 , one end of the elastic member abuts against the clamping plate 4 , and when the rotating column 3 is reset, the elastic member provides elastic force for the clamping plate 4 to reset.

[0046] Furthermore, a guide cylinder 103 is provided at the center of the upper surface of the base plate 1, and the sliding column 2 is slidably set in the guide cylinder 103. The guide cylinder 103 has a first sliding groove 104, and the guide cylinder 103 also has a second sliding groove 105. The second sliding groove 105 is vertically connected to the first sliding groove 104, and also includes: one end of the second follower rod 11 is fixedly set on the rotating column 3, and the other end of the second follower rod 11 is slidably set in the first sliding groove 104.

[0047] In this embodiment, a guide cylinder 103 is provided on the base plate 1, and the sliding column 2 slides in the guide cylinder 103. A first slide groove 104 and a second slide groove 105 are provided in the guide cylinder 103. The first slide groove 104 and the second slide groove 105 are vertically connected. When the sliding column 2 slides out, the second follower rod 11 slides in the first slide groove 104. When the sliding column 2 slides into place, the rotating column 3 is rotated, and the second follower rod 11 will slide from the first slide groove 104 to the second slide groove 105, thereby fixing the position of the sliding column 2.

[0048] Furthermore, the second follower rods 11 are used in pairs, and the second follower rods 11 used in pairs are symmetrically arranged on the rotating column 3 .

[0049] In this embodiment, there are a plurality of second follower rods 11 on the rotating column 3 . The second follower rods 11 are symmetrically installed and are used to prevent the sliding column 2 from sliding out along the first sliding groove 104 after the sliding column 2 slides into place.

[0050] Furthermore, a second elastic member 10 is included. One end of the second elastic member 10 is fixedly disposed in the guide cylinder 103 to provide elastic force for the sliding column 2 to move away from the bottom plate 1 .

[0051] In this embodiment, when the pump casing is being processed, the second follower rod 11 is located in the second slide groove 105. At this time, the second elastic member 10 provides an elastic force for the sliding column 2 to move away from the base plate 1, so that the second follower rod 11 is tightly abutted against the second slide groove 105. When the pump casing is processed, the rotating column 3 is rotated to make the second follower rod 11 slide from the second slide groove 105 to the first slide groove 104. The second elastic member 10 provides an elastic force for the sliding column 2 to move away from the base plate 1, so that the sliding column 2 slides out. After sliding out, the processed pump casing can be removed.
