[0051] Please refer to Figures 1 to 10, this embodiment provides a rotary table for machining a pump housing.

The rotary table for machining the pump housing includes a rotating table 1 and a milling module 2.

[0052] The rotating table 1 is used to install the pump housing 100 so that the axis of the flow channel of the pump housing 100 is horizontal.

[0053] The milling module 2 includes a motor assembly and a transmission rod 21. The transmission rod 21 is connected to the motor assembly and driven by it to move. A milling cutter 22 extending radially along the transmission rod 21 is provided on the transmission rod 21. The milling cutter 22 includes an axial milling edge 221 and a radial milling edge 222. The axial milling edge 221 is used to mill the series of holes 110, and the radial milling edge 222 is used to mill the shaft seal plane 120.

[0054] Among them, the rotating table 1 can be installed on the motor of the machine tool. When fixing the pump housing 100, the foot plate at the lower half of the pump housing 100 can be locked on the rotating table 1 through a floor nut. After moving the transmission rod 21 and the milling cutter 22 into the cavity of the pump housing 100, the upper half of the pump housing 100 is then connected to the lower half and tightened with bolts. The motor assembly can drive the transmission rod 21 to rotate or swing to drive the milling cutter 22 to move, so that the axial milling edge 221 and the radial milling edge 222 mill the series of holes 110 and the shaft seal plane 120. When one side in the cavity of the pump housing 100 is milled, the rotating table 1 can be rotated so that the milling cutter 22 continues to mill the other side in the cavity of the pump housing 100.

[0055] A rotary table for machining a pump housing provided in this embodiment, by setting the rotating table, enables the pump housing to be placed on the rotating table to change its orientation, and by setting the transmission rod and the milling cutter, enables the milling cutter to extend into the cavity of the pump housing to mill the series of holes and the shaft seal plane, solving the problem that it is difficult to machine a multi-cavity structure pump housing using traditional methods.

[0056] Further, please refer to Figure 5 , the milling cutter 22 further includes a connecting rod 223. One end of the connecting rod 223 is connected to the transmission rod 21, and the other end forms the axial milling edge 221 and the radial milling edge 222. Specifically, the connecting rod 223 extends radially along the transmission rod 21. When the connecting rod 223 rotates or swings, the axial milling edge 221 and the radial milling edge 222 at the end of the connecting rod 223 can machine the pump housing 100.

[0057] Further, please continue to refer to Figure 5 , in the embodiment provided in this embodiment:

[0058] An axial milling edge 221 is formed on the side of the end face of the connecting rod 223 away from the transmission rod 21.

[0059] On the side of the end of the connecting rod 223 far from one end of the transmission rod 21, a radial milling edge 222 is formed.

[0060] Specifically, the connecting rod 223 is integrally in the shape of a cuboid, and the axial milling edge 221 is the edge of the cuboid on the side far from the transmission rod 21, and this edge is parallel to the length direction of the transmission rod 21, so as to be able to mill the string hole 110 when the transmission rod 21 rotates.

[0061] The radial milling edge 222 is the edge of the cuboid extending along the radial direction of the transmission rod 21, so as to be able to mill the shaft seal plane 120 when the connecting rod 223 rotates.

[0062] Further, please refer to Figure 6 , the connecting rod 223 is connected to the transmission rod 21 through a sliding locking structure 23, and the sliding locking structure 23 includes a first limiting portion 231, a second limiting portion 232 and a locking member 233.

[0063] The first limiting portion 231 is arranged on the transmission rod 21.

[0064] The second limiting portion 232 is arranged on the connecting rod 223, and the second limiting portion 232 is in sliding fit with the first limiting portion 231 so that the connecting rod 223 can move radially along the transmission rod 21.

[0065] The locking member 233 is connected between the first limiting portion 231 and the second limiting portion 232 and is used to limit the relative sliding between the first limiting portion 231 and the second limiting portion 232.

[0066] Wherein, the cooperation between the first limiting portion 231 and the second limiting portion 232 enables the connecting rod 223 to move radially along the transmission rod 21, so as to adjust the length of the connecting rod 223, and further change the position of the milling cutter 22, so that the string holes 110 with various sizes in the cavity of the pump casing 100 can be milled.

[0067] Further, please refer to Figure 7 , in the embodiment provided in this embodiment:

[0068] The first limiting portion 231 is a chute, and the second limiting portion 232 is a slider.

[0069] Or the first limiting portion 231 is a slider, and the second limiting portion 232 is a chute.

[0070] Wherein, the slider can slide in the chute, so that the connecting rod 223 slides radially relative to the transmission rod 21, thereby changing the distance between the end of the connecting rod 223 and the transmission rod 21.

[0071] Further, please refer to Figure 8 , the locking member 233 includes a threaded hole 2331 and a bolt 2332.

[0072] The threaded hole 2331 is provided through one side of the chute.

[0073] The bolt 2332 is in threaded fit with the threaded hole 2331.

[0074] Wherein, when the connecting rod 223 slides to a proper position, the bolt 2332 can be tightened into the threaded hole 2331, so that the end of the bolt 2332 abuts against the connecting rod 223, thereby locking the relative sliding of the connecting rod 223 and the transmission rod 21.

[0075] Further, the milling and boring module 2 may further include a boring and milling cutter, and the boring and milling cutter is connected to the transmission rod 21 through a sliding locking structure 23, so that the boring and milling cutter can perform boring and milling on the cavity of the pump housing 100 when the transmission rod 21 swings.

[0076] Further, the rotating table 1 is circular to facilitate rotation.

[0077] Further, please refer to Figure 9 , the rotating table 1 includes a mounting table 11 and a supporting table 12.

[0078] The mounting table 11 is used for mounting the pump housing 100.

[0079] A fixing kit 13 is provided on the supporting table 12, and the fixing kit 13 is used for fixing the mounting table 11 on the supporting table 12.

[0080] Wherein, there may be multiple fixing kits 13, and the multiple fixing kits 13 can fix the four corners of the mounting table 11. When fixing the pump housing 100, after the pump housing 100 is mounted on the mounting table 11, the mounting table 11 is then fixed on the supporting table 12. When milling and boring different orientation positions of the pump housing 100, only the mounting table 11 needs to be rotated, and there is no need to refix the pump housing 100.

[0081] Further, please refer to Figure 9 and Figure 10 , a plurality of slide rails 121 are arranged side by side on the supporting table 12, and the fixing kit 13 includes a clamping plate 131, a connecting rod 132 and a fixing rod 133.

[0082] One end of the clamping plate 131 abuts against the supporting table 12, and the other end abuts against the mounting table 11.

[0083] One end of the connecting rod 132 is slidably arranged in the slide rail 121, and the other end movably penetrates through the middle of the clamping plate 131.

[0084] The fixing member 133 is arranged at the end of the connecting rod 132 away from the slide rail 121 and is located on the side of the clamping plate 131 away from the supporting table 12.

[0085] Among them, the connecting rod 132 can be a bolt, and the bolt head is located inside the slide rail 121. The fixing member 133 can be a nut. The end of the connecting rod 132 is slidably arranged inside the slide rail 121, and the relative positions between multiple fixing kits 13 can be adjusted. After the position of the connecting rod 132 is adjusted, the end of the mounting clamping plate 131 abuts against the mounting table 11. Then, the fixing member 133 is tightened so that the mounting clamping plate 131 presses the mounting table 11 against the supporting table 12, and at the same time, the part of the connecting rod 132 located inside the slide rail 121 is locked. To ensure the pressing effect of the mounting clamping plate 131, a downward convex block can be provided at one end of the armor plate 131 away from the supporting table 12, and the height of the convex block is consistent with the thickness of the mounting table 11. When the mounting clamping plate 131 presses the mounting table 11, the armor plate 131 can remain horizontal.

[0086] Working principle: When milling the pump casing 100 is required, first fix the lower half of the pump casing 100 on the rotating table 1 by tightening the foot plate with the anchor nut. At this time, the transmission rod 21 can be moved so that the milling cutter 22 is located at the part to be milled inside the pump casing 100. Then, the upper half of the pump casing 100 is installed with the lower half through bolts. After starting the motor assembly, the transmission rod 21 drives the milling cutter 22, thereby milling the inside of the pump casing 100. After one side inside the cavity of the pump casing 100 is milled, the upper half of the pump casing 100 can be removed. After rotating the rotating table 1, the other side inside the cavity of the pump casing 100 is milled again according to the above steps.

[0087] The sliding locking structure 23 can be slidably fixed on the transmission rod 21 through the connecting rod 223 to change the position of the milling cutter 22, and the cutter head of the milling cutter 22 can also be replaced with a boring and milling cutter to adapt to the processing of different-sized parts inside the pump casing 100.
