[0002] The pump casing is an important concept in the field of mechanical engineering and is mainly applied to the design and manufacture of pumps. As the outer wall of the pump, the main function of the pump casing is to separate the low-pressure gas from the atmosphere, and at the same time to separate the pumped medium from the atmosphere to prevent leakage and maintain pressure.

After the cutting is completed, the staff needs to manually unload the cut pump casings. The pump casings themselves have a certain weight. After repeated operations for a long time, it will cause the staff to be fatigued, thus reducing the unloading efficiency, and therefore also reducing the cutting efficiency.

The pneumatic fixture 2, the rotating mechanism 3, the positioning die 4, and the cutting wheel 5 are all existing mature technical products, so the specific structures and usage processes are not elaborated too much.

[0031] It further includes a long box 6 fixedly installed on the base 1, a collection box 7 for collecting the pump shell, a connecting plate 28 fixedly installed on the outer wall of one side of the collection box 7, a pushing mechanism provided on the outer wall of one side of the collection box 7, and a moving mechanism provided in the long box 6 and used for driving the collection box 7 to move.

[0032] The moving mechanism includes a screw rod 10 rotatably installed in a long box 6, a threaded block 11 screwed onto the screw rod 10, a mounting plate 27 fixedly installed on the outer wall of one side of the threaded block 11, a connecting rod 12 fixedly installed on the mounting plate 27, a collection box 7 fixedly installed at one end of the connecting rod 12, a support plate 8 fixedly installed on one side of the long box 6, a first motor 9 fixedly installed on the support plate 8, the screw rod 10 fixedly installed on the output end of the first motor 9, a partition plate 17 fixedly installed on the inner wall of the bottom of the collection box 7, sliding grooves 16 opened on the collection box 7 and the partition plate 17 for slidingly installing a baffle 15, and rubber pads provided on multiple baffles 15 for protection; the long box 6 is fixed to the base 1 by bolts, facilitating disassembly, installation and maintenance.

[0033] During use, by controlling the start of the first motor 9, the output end of the first motor 9 will drive the screw rod 10 to rotate and drive the threaded block 11 to move. The threaded block 11 moves and drives the connecting rod 12 and the collection box 7 fixed to the connecting rod 12 to move. The collection box 7 moves and drives the square connecting plate 28 and the installation box 18 to move, so as to push the collection box 7 to move under the positioning die 4. Then, when the pump shell is flipped after being cut, the pump shell will fall into the collection box 7 to complete the collection.

[0034] Specifically, please refer to Figure 2 、 Figure 4 、 Figure 5 The pushing mechanism includes an installation box 18 fixedly installed on the outer wall of the bottom of the connecting plate 28, a box door 14 slidingly installed on one side of the collection box 7, a box groove 13 opened for slidingly installing the threaded block 11, two rack plates 22 slidingly installed on the inner wall of the bottom of the installation box 18, two gears 23 rotatably installed on the inner wall of the bottom of the installation box 18 and meshing with the two rack plates 22, two pushing plates 20 fixedly installed on the outer wall of one side of the two rack plates 22, a long groove 21 opened for the two rack plates 22 to move, a fixing frame 26 provided on the outer wall of the top of the installation box 18, a second motor 25 fixedly installed on the fixing frame 26, a rotating column 24 fixedly installed on the output end of the second motor 25, and one of the gears 23 fixedly connected to one end of the rotating column 24. The pushing plate 20 is composed of a vertical plate 201 and multiple horizontal plates 202 perpendicular to the vertical plate 201, and the multiple horizontal plates 202 are respectively located above the corresponding baffles 15. The lengths of the multiple horizontal plates 202 are the same as the length of the partition plate 17, so as to ensure that the horizontal plates 202 push the pump shells on the baffles 15 to realize discharging, and there is a gap exceeding the length of the pump shell between the initial position of the whole device before use and the pump shell falling point of the horizontal plates 202, so as not to prevent the pump shell from falling on the baffle 15 and facilitating subsequent discharging.

[0035] During use, by controlling the start of the second motor 25, the output end of the second motor 25 will drive the rotating column 24 and one of the gears 23 to rotate, and will also drive the other gear 23 to rotate accordingly. Then, it will drive the two rack plates 22 and the two vertical plates 201 to move. The movement of the two vertical plates 201 will push the corresponding transverse plates 202 to move, and push out multiple pump casings, thereby completing the discharging of the pump casings.

[0036] Specifically, please refer to Figure 3 , and two pushing openings 19 for the movement of the two pushing plates 20 are formed on the outer wall of one side of the collecting box 7. By providing the pushing openings 19, it is convenient for the transverse plate 202 to push the pump casing for blanking.

[0037] Working principle: During use, first insert one end of the pump casing casting onto the positioning die 4 of the rotating mechanism 3, and at the other end, start the pneumatic fixture 2 and clamp the pump casing casting through the pneumatic fixture 2. At this time, the cutting wheel 5 can be used to cut off one side of the pump casing, and then the rotating mechanism 3 drives the turntable on the rotating mechanism 3 to rotate, so that the other side of the pump casing is turned up, and then the gate on the other side of the pump casing can also be cut off, thereby completing the separation and cutting of the two pump casings;

[0038] During the cutting process, by controlling the start of the first motor 9, the output end of the first motor 9 will drive the screw rod 10 to rotate. The rotation of the screw rod 10 will drive the threaded block 11 to move. The movement of the threaded block 11 will drive the connecting rod 12 and the collecting box 7 fixed to the connecting rod 12 to move. The movement of the collecting box 7 will drive the square connecting plate 28 and the installation box 18 to move, thereby pushing the collecting box 7 to move under the positioning die 4. Then, when the pump casing is turned over after the cutting is completed, the pump casing will fall into the collecting box 7 to complete the collection;

[0039] After the collection of the two pump casings is completed, by pushing one of the baffles 15 to move and covering the two pump casings in the collecting box 7, the multiple pump casings can be separated and collected, thereby avoiding the phenomenon that multiple pump casings collide with each other during blanking and are damaged, and thus improving the protection during the collection of the pump casings;

[0040] When it is necessary to discharge the multiple pump casings in the collecting box 7, first open the box door 14, and then control the start of the second motor 25. The output end of the second motor 25 will drive the rotating column 24 and one of the gears 23 to rotate, and will also drive the other gear 23 to rotate accordingly. Then, it will drive the two rack plates 22 and the two vertical plates 201 to move. The movement of the two vertical plates 201 will push the corresponding transverse plates 202 to move, thereby completing the discharging of the pump casings.

[0041] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features.
