[0002] In the manufacturing process of submersible pumps, the pump casing is one of its important components. The pump casing is usually made of metal materials (such as cast iron, stainless steel, etc.) and is made by casting or machining. Casting may leave some sharp corners (burrs) in the early stage of production, while machining may cause small protrusions or gaps on the surface during the cutting process due to high material hardness or unreasonable cutting parameter settings. These burrs not only affect the appearance, but may also become the cause of early failure of parts, causing safety hazards.

DETAILED DESCRIPTION

[0024] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0025] The following describes a submersible pump casing processing device according to an embodiment of the present application with reference to the accompanying drawings.

[0026] like Figure 1-Figure 6 As shown, the submersible pump casing processing device of the embodiment of the present application may include: a support frame 1, two reciprocating drive modules 2, a rotary clamping mechanism 3 and a processing mechanism 4.

[0027] Among them, two reciprocating drive modules 2 are symmetrically arranged on the support frame 1, and the reciprocating drive module 2 is used to drive the rotary clamping mechanism 3 and the processing mechanism 4 to move reciprocally at a uniform speed.

[0028] It should be noted that the specific structure of the reciprocating drive module 2 described in this embodiment has been disclosed in the prior art, so it will not be described in detail here.

[0029] The rotary clamping mechanism 3 is installed on the sliders of the two reciprocating drive modules 2, and the rotary clamping mechanism 3 is used to clamp and fix the pump casing to be processed.

[0030] The processing mechanism 4 includes a base plate 41 , two longitudinal drive assemblies 42 , a grinding assembly 43 and a rotation drive assembly 44 .

[0031] Among them, the two longitudinal drive components 42 are respectively connected to the sliders of the corresponding reciprocating drive module 2, the base plate 41 is arranged between the two longitudinal drive components 42, the longitudinal drive component 42 is used to drive the base plate 41 to move along the vertical direction of the ground, and the grinding component 43 is arranged below the base plate 41, and the grinding component 43 is used to grind the burrs on the inner wall and outer wall of the pump casing opening.

[0032] The grinding assembly 43 includes two first hydraulic retractors 431 , two connecting blocks 432 , four connecting rods 433 , two grinding rollers 434 and two rod bodies 435 .

[0033] Among them, two first hydraulic telescoping devices 431 are symmetrically arranged on the base plate 41, two connecting blocks 432 are respectively connected to the telescopic ends of the corresponding first hydraulic telescoping devices 431, one end of two connecting rods 433 is pivotally connected to the connecting block 432, one end of the two connecting rods 433 is pivotally connected to one end of the other two connecting rods 433, the four connecting rods 433 are arranged in a quadrilateral structure, two grinding rollers 434 are rotatably arranged on the quadrilateral structure, and one end of the two rod bodies 435 is connected to one end of the corresponding grinding rollers 434.

[0034] A first guide groove 430 is defined on the base plate 41 . Two rod bodies 435 penetrate through the first guide groove 430 . The rotation driving assembly 44 is disposed on the base plate 41 . The rotation driving assembly 44 is connected to the two rod bodies 435 .

[0035] Specifically, the relevant technicians use the device to grind and deburr the open mouth of the pump casing. First, the rotary clamping mechanism 3 and the processing mechanism 4 in the device are placed at one end (initial position) of the reciprocating drive module 2.

[0036] An external material gripping tool (eg, a robotic arm) is used to pick up a pump casing to be processed, and the pump casing is placed inside the rotating clamping mechanism 3 . Under the action of the rotating clamping mechanism 3 , the pump casing to be processed is fixed.

[0037] Afterwards, the processing mechanism 4 starts running, and the longitudinal driving assembly 42 drives the base plate 41 to move downward, so that the grinding roller 434 in the grinding assembly 43 is placed inside the pump housing and directly opposite to the position to be ground of the pump housing, and the two first hydraulic telescopes 431 start to run, and the first hydraulic telescopes 431 push the connecting block 432, and the connecting block 432 drives the connecting rod 433, and the four connecting rods 433 are pivotally connected, and the two grinding rollers 434 move away from each other until the two grinding rollers 434 collide with the inner wall of the pump housing.

[0038] It should be noted that in order to avoid excessive force between the grinding roller 434 and the pump casing, a pressure sensor (not shown in the figure) can be set between the grinding roller 434 and the rod body 435. The pressure sensor can monitor the specific value of the reaction force applied by the pump casing to the grinding roller 434. Due to the linkage effect of the four connecting rods 433, it can be ensured that the force between the two grinding rollers 434 and the pump casing is equal, thereby ensuring the uniformity of grinding. This not only saves some manpower, but also reduces the technical requirements for relevant technical personnel, ensures the quality of pump casing processing, and the pump casing is evenly stressed during the grinding process, thereby avoiding the situation of detachment from the device.

[0039] The rotary drive assembly 44 starts to run, and the rotary drive assembly 44 drives the two grinding rollers 434 to rotate rapidly, thereby grinding and deburring a part of the pump casing. At the same time, the rotary clamping mechanism 3 can drive the pump casing to rotate slowly and uniformly, thereby completing the processing of the pump casing.

[0040] When the outer wall of the pump casing needs to be polished, the first hydraulic expander 431 pushes the connecting block 432 to move, and the connecting block 432 drives the connecting rod 433 to move. The quadrilateral structure surrounded by multiple connecting rods 433 is deformed, so that the grinding roller 434 is placed on the outside of the pump casing. The above steps are repeated to complete the polishing of the outer wall of the pump casing.

[0041] In one embodiment of the present application, Figure 3 As shown, the rotary drive assembly 44 includes two driven wheels 441 , a driving wheel 442 , a driving motor 443 , a tensioning wheel 444 , an auxiliary component 445 and a transmission belt 446 .

[0042] Among them, the two driven wheels 441 are respectively connected to the corresponding rod bodies 435, the driving wheel 442 is rotatably connected to the base plate 41, the driving motor 443 is installed on the base plate 41, the output shaft of the driving motor 443 is connected to the driving wheel 442, the auxiliary component 445 is arranged on the base plate 41, the tensioning wheel 444 is connected to the auxiliary component 445, and the transmission belt 446 is wound around the outside of the two driven wheels 441, the driving wheel 442 and the tensioning wheel 444.

[0043] In one embodiment of the present application, Figure 2As shown, the auxiliary component 445 includes a frame 4451 , a limit block 4452 , a guide rod 4453 and a spring 4454 .

[0044] Among them, the frame 4451 is set on the base plate 41, the guide rod 4453 is set inside the frame 4451, the limit block 4452 is slidably set on the guide rod 4453, the base plate 41 is opened with a second guide groove 440, the top of the limit block 4452 passes through the second guide groove 440, the tensioning wheel 444 is rotatably connected with the limit block 4452, and the spring 4454 is sleeved on the outside of the guide rod 4453.

[0045] Specifically, during the operation of the rotary drive assembly 44, the driving motor 443 drives the driving wheel 442 to rotate, and under the connection of the transmission belt 446, the two driven wheels 441 rotate, thereby driving the grinding rollers 434 of the rod body 435 to rotate, and then grinding the pump casing.

[0046] When the grinding assembly 43 is deformed, that is, the distance between the two grinding rollers 434 is changed, the distance between the two driven wheels 441 is changed. At this time, under the action of the tensioning wheel 444, the transmission belt 446 follows the deformation of the two driven wheels 441, and the transmission belt 446 will not separate from the driven wheels 441.

[0047] During the movement of the tension wheel 444 , the elastic potential energy of the spring 4454 pushes the limit block 4452 to move along the guide rod 4453 , and the limit block 4452 drives the tension wheel 444 to move, thereby adapting to the deformation of the transmission belt 446 .

[0048] In one embodiment of the present application, Figure 4 As shown, the rotary clamping mechanism 3 includes two first drives 31 , two support frames 32 , two clamping jaws 33 , a slewing bearing 34 and a rotary drive 35 .

[0049] Among them, the slewing bearing 34 is arranged on the sliders of the two reciprocating drive modules 2, the two first drivers 31 are symmetrically installed on the outer wall of the slewing bearing 34, the two support frames 32 are connected to the outer sides of the corresponding first drivers 31, the telescopic rods of the first drivers 31 are slidably connected to the support frames 32, and the two clamps 33 are connected to the telescopic rods of the corresponding first drivers 31, and the clamps 33 are arranged in a V-shaped structure.

[0050] It should be noted that the first driver 31 described in this embodiment can be a rotary driver. The first driver 31 drives the clamping jaws 33 to rotate, and the two clamping jaws 33 rotate in opposite directions. The clamping jaws 33 contact the upper and lower parts of the pump housing, thereby fixing the pump housing.

[0051] It can be understood that the connection mode in which the clamping jaws 33 abut against the upper and lower parts of the pump housing enables the rotary clamping mechanism 3 to be suitable for pump housings with a greater height, thereby ensuring stable clamping and preventing the pump housing from escaping from the fixture during processing.

[0052] The rotary driver 35 is mounted on a slider of a reciprocating drive module 2 , and the rotary driver 35 is connected to the inner ring of the slewing bearing 34 .

[0053] It should be noted that the inner ring of the slewing bearing 34 described in this embodiment is provided with a gear ring (not shown in the figure), and the rotary driver 35 can be meshed with the gear ring through a gear, thereby driving the inner ring of the slewing bearing 34 to rotate.

[0054] Specifically, the external robotic arm places the pump casing to be processed inside the rotating clamping mechanism 3, and the first driver 31 drives the clamping jaws 33 to rotate, thereby fixing the pump casing. After the processing mechanism 4 is placed in a preset position, the rotating driver 35 drives the inner ring of the slewing bearing 34 to rotate, so that the pump casing rotates slowly and at a uniform speed, thereby continuously changing the processing position of the pump casing.

[0055] In one embodiment of the present application, Figure 5 As shown, the longitudinal drive assembly 42 includes a connecting frame 421 and a second hydraulic retractor 422 .

[0056] The connection frame 421 is connected to the slider of the reciprocating drive module 2 , the second hydraulic retractor 422 is installed on the connection frame 421 , and the telescopic end of the second hydraulic retractor 422 is connected to the base plate 41 .

[0057] In one embodiment of the present application, Figure 6 As shown, a plurality of spiral grooves 51 are formed on the outer wall of the grinding roller 434 .

[0058] It is understandable that the provision of a plurality of spiral grooves 51 rotating toward the ground can guide the metal particles after grinding, thereby preventing the metal particles from being spattered randomly and ensuring the production safety of the factory.

[0059] In one embodiment of the present application, Figure 1 As shown, a material collecting box 61 is provided on the support frame 1.

[0060] It is understandable that the collection box 61 can collect the metal particles, thereby facilitating unified processing.

[0061] In summary, the submersible pump casing processing device of the embodiment of the present application, by arranging the grinding component into a quadrilateral structure, under the linkage action of the first hydraulic expander, the connecting block and the connecting rod, the two grinding rollers can simultaneously interfere with the pump casing, and the rotating clamping mechanism can fix the pump casing and drive it to rotate at a uniform speed, which not only saves some manpower, but also reduces the technical requirements for relevant technical personnel, ensures the quality of pump casing processing, and ensures that the pump casing is evenly stressed during the grinding process, thereby avoiding the situation of detachment from the device.
