DETAILED DESCRIPTION

[0022] Example 1

[0023] As Figs. 1-5As shown, a milling machine fixture for machining the verticality of a pump body includes a worktable 1. A bottom support assembly and two quick positioning assemblies are mounted on the worktable 1. An angle adjustment assembly is connected to the bottom of the worktable 1. The two quick positioning assemblies are located at both ends of the support assembly. The support assembly includes a connecting plate 2, which is installed in the middle of the worktable 1. Multiple support columns 201 are arranged in an array on the top of the connecting plate 2. A butterfly spring 202 is installed on the support column 201. A spherical contact head 203 is installed on the top of the butterfly spring 202. The quick positioning assembly includes a linear slide rail 3. Two linear slide rails 3 are mounted on the same base plate and located at both ends of the connecting plate 2. A sliding block 4 is slidably connected to the linear slide rail 3. A V-shaped block 5 is installed on the top of the sliding block 4. A V-shaped opening 6 is opened on the V-shaped block 5. An adjustment component is connected to one side of the sliding block 4.

[0024] During operation, when placing a cylindrical pump body with flanges at both ends and an irregularly shaped casing, such as a pipeline pump, two V-blocks 5 are symmetrically arranged so that the flanges on the pipeline pump are placed within the V-shaped openings 6 on the two V-blocks 5 to support the outer circle of the flanges, ensuring that the casing axis is parallel to the reference plane. The middle part of the pipeline pump casing is supported by multiple butterfly springs 202 and spherical contact heads 203 on the bottom support assembly. The weight of the pipeline pump casing compresses the butterfly springs 202, causing the spherical contact heads 203 of the support column 201 to press firmly against the bottom of the pump body under the action of the butterfly springs. The surface is designed to compensate for unevenness at the bottom. For example, when placing a water pump impeller housing, the shape is an eccentric cylinder and a partial plane. Two V-blocks 5 are arranged asymmetrically, with one side supporting the impeller journal and the other side supporting the housing plane. The middle of the pump body is supported by the spherical contact head 203 of the bottom support component. It contacts the outer circular surface of the pump body flange through the V-shaped opening 6, realizing the radial positioning of the pump body and the self-centering positioning of the pump body axis. This allows the fixture to quickly position the pump body when placing it. The combination of the quick positioning component and the bottom support component makes the placement and positioning of the pump body fast and accurate.

[0025] like Figs. 2-4 As shown, the adjusting component includes a drive block 7 and a linear screw 8. The drive block 7 is installed on one side of the sliding block 4, and the linear screw 8 is threadedly connected to the drive block 7. The two ends of the linear screw 8 are rotatably connected to limit blocks 9, and the bottoms of the two limit blocks 9 are installed on the same worktable 1.

[0026] During operation, the linear screw 8 is rotated, causing the linear screw 8 to rotate on the limit block 9, which drives the drive block 7 connected to it to move horizontally. The drive block 7 drives the sliding block 4 to slide on the linear slide rail 3, which in turn drives the V-block 5 connected to it to move horizontally. This adjusts the length between the two V-blocks 5 to adapt to the rapid positioning of pump bodies of different lengths.

[0027] By rotating the straight screw rod 8 on the adjusting member, the distance between the V-shaped blocks 5 can be easily adjusted to adapt to pump bodies of different lengths, greatly improving the flexibility and adaptability of the clamp.

[0028] Embodiment 2

[0029] As shown in Figs. 1-6 The angle adjusting assembly comprises two rotating shafts 11 and two supporting blocks 10. The two rotating shafts 11 are installed on the two sides of the workbench 1, and the rotating shaft 11 is rotatably connected to the supporting block 10.

The worm wheel 12 is installed in the middle of the rotating shaft 11. The connecting plate 2 is provided with a digital angle gauge 22 in the middle.

[0030] In operation, the pump body is clamped and fixed by the two clamping pieces. Then the hand wheel 15 is rotated to drive the driving shaft 14 to rotate on the supporting block 10. The driving shaft 14 drives the connected worm 13 to rotate. The worm 13 drives the connected worm wheel 12 to rotate, thereby driving the rotating shaft 11 connected to the worm wheel 12 to rotate. The rotating shaft 11 drives the workbench 1 connected thereto to adjust the angle, so that the pump body on the workbench 1 is adjusted in angle. The digital angle gauge 22 displays the angle of inclination. By reducing the perpendicularity error between the pump body processing surface and the milling cutter spindle, the high-precision machining requirement is met.

[0031] The clamping piece comprises a mounting plate 17 installed on the supporting block 10. The mounting plate 17 is provided with an electric telescopic rod 18. The electric telescopic rod 18 is provided with a fixed block 19. The fixed block 19 is provided with a thimble 20 in the middle. The two sides of the fixed block 19 are provided with auxiliary clamping blocks 21.

[0032] In operation, the electric telescopic rod 18 drives the thimbles 20 and the auxiliary clamping blocks 21 on the fixed block 19 to clamp on the two sides of the pump body, thereby fixing the pump body. The pump body is more stable during machining. The two thimbles 20 contact the pump body to realize point contact precise clamping and limit the radial displacement of the pump body. The surface of the auxiliary clamping block 21 is coated with a polyurethane or rubber layer to provide surface contact dispersion pressure and avoid local deformation.
