Description

Technical Field

[0001] This application relates to the field of submersible pump technology, and in particular to a submersible pump casing processing device. Background Technology

[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 manufactured through casting or machining. Casting may leave some sharp edges (burrs) in the early stages of production, while machining may cause small protrusions or gaps on the surface due to high material hardness or improper cutting parameters during the cutting process. These burrs not only affect the appearance but may also become a cause of premature component failure, creating safety hazards.

[0003] In related technologies, deburring of pump casings is generally done by grinding with mechanical tools (e.g., angle grinders). This processing method is not only time-consuming and labor-intensive, but it is also difficult for relevant technicians to control the grinding precision, which can easily lead to damage to the pump casing. In addition, for pump casings with large height, the uneven force on the pump casing during grinding can easily cause the pump casing to detach from the fixture. Summary of the Invention

[0005] Therefore, one objective of this application is to provide a submersible pump casing processing device that uses a rotary clamping mechanism to fix the pump casing and a grinding assembly to grind the pump casing.

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

[0025] The submersible pump casing processing apparatus of this application is described below with reference to the accompanying drawings.

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

[0027] Two reciprocating drive modules 2 are symmetrically arranged on the support frame 1. The reciprocating drive modules 2 are used to drive the rotary clamping mechanism 3 and the processing mechanism 4 to move back and forth at a constant 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. The rotary clamping mechanism 3 is used to clamp and fix the pump housing to be processed.

[0030] The processing mechanism 4 includes a base plate 41, two longitudinal drive components 42, a grinding component 43, and a rotary drive component 44.

[0031] Two longitudinal drive components 42 are respectively connected to the sliders of the corresponding reciprocating drive module 2. The base plate 41 is disposed between the two longitudinal drive components 42. The longitudinal drive components 42 are used to drive the base plate 41 to move vertically along the ground. The grinding component 43 is disposed below the base plate 41. The grinding component 43 is used to grind the burrs on the inner and outer walls of the pump housing opening.

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

[0033] Two first hydraulic expansion joints 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 expansion joints 431. One end of two connecting rods 433 is pivotally connected to the connecting blocks 432. One end of 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. One end of two rods 435 is connected to one end of the corresponding grinding rollers 434.

[0034] A first guide groove 430 is provided on the substrate 41, and two rods 435 pass through the first guide groove 430. A rotation drive assembly 44 is disposed on the substrate 41 and is connected to the two rods 435.

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

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

[0037] Afterwards, the processing mechanism 4 operates, and the longitudinal drive component 42 drives the base plate 41 to move downward, so that the grinding roller 434 in the grinding component 43 is placed inside the pump housing and directly opposite the position to be ground in the pump housing. The two first hydraulic telescopic devices 431 start to operate, and the first hydraulic telescopic devices 431 push the connecting block 432. The connecting block 432 drives the connecting rod 433. 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 abut against 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 housing, a pressure sensor (not shown in the figure) can be installed between the grinding roller 434 and the rod 435. The pressure sensor can monitor the specific value of the reaction force applied by the pump housing to the grinding roller 434. Due to the linkage effect of the four connecting rods 433, the force between the two grinding rollers 434 and the pump housing can be guaranteed to be equal, thus ensuring the uniformity of grinding. This not only saves some manpower but also reduces the technical requirements for relevant technicians, ensures the quality of pump housing processing, and ensures that the pump housing is subjected to uniform force during the grinding process, thereby preventing the pump housing from detaching from the device.

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

[0040] When the outer wall of the pump casing needs to be polished, the first hydraulic telescopic device 431 pushes the connecting block 432 to move, the connecting block 432 drives the connecting rod 433 to move, and the quadrilateral structure formed by multiple connecting rods 433 deforms, so that the grinding roller 434 is placed on the outside of the pump casing. By repeating the above steps, the polishing process of the outer wall of the pump casing can be completed.

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

[0042] Two driven wheels 441 are connected to corresponding rods 435 respectively, a driving wheel 442 is rotatably connected to a base plate 41, a drive motor 443 is mounted on the base plate 41, the output shaft of the drive motor 443 is connected to the driving wheel 442, an auxiliary component 445 is disposed on the base plate 41, a tensioning wheel 444 is connected to the auxiliary component 445, and a 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 this application, such as Figure 2As shown, the auxiliary component 445 includes a frame 4451, a limiting block 4452, a guide rod 4453, and a spring 4454.

[0044] The frame 4451 is mounted on the base plate 41, the guide rod 4453 is mounted inside the frame 4451, the limiting block 4452 is slidably mounted on the guide rod 4453, the base plate 41 is provided with a second guide groove 440, the top of the limiting block 4452 passes through the second guide groove 440, the tension wheel 444 is rotatably connected to the limiting 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 drive motor 443 drives the drive wheel 442 to rotate. Under the connection of the transmission belt 446, the two driven wheels 441 rotate, thereby driving the rod body 435 and the grinding rollers 434 to rotate, and thus grinding the pump casing.

[0046] When the grinding assembly 43 deforms, that is, when the distance between the two grinding rollers 434 changes, the distance between the two driven rollers 441 changes. At this time, under the action of the tensioner 444, the transmission belt 446 deforms along with the two driven rollers 441, and the transmission belt 446 will not detach from the driven rollers 441.

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

[0048] In one embodiment of this application, such as Figure 4 As shown, the rotary clamping mechanism 3 includes two first drivers 31, two support frames 32, two grippers 33, a slewing bearing 34, and a rotary driver 35.

[0049] The slewing bearing 34 is mounted on the sliders of the two reciprocating drive modules 2. The two first drivers 31 are symmetrically mounted on the outer wall of the slewing bearing 34. The two support frames 32 are connected to the outer side of the corresponding first drivers 31. The telescopic rods of the first drivers 31 are slidably connected to the support frames 32. The two grippers 33 are connected to the telescopic rods of the corresponding first drivers 31. The grippers 33 are arranged in a V-shape.

[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 gripper 33 to rotate, and the two grippers 33 rotate in opposite directions. The grippers 33 abut against the upper and lower parts of the pump housing, thereby fixing the pump housing.

[0051] Understandably, the way the gripper 33 contacts the upper and lower parts of the pump housing allows this rotary clamping mechanism 3 to be suitable for pump housings with greater height, ensuring stable clamping and preventing the pump housing from detaching from the fixture during processing.

[0052] The rotary driver 35 is mounted on the 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). The rotary drive 35 can be connected to the gear ring through gear meshing, 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 rotary clamping mechanism 3. The first driver 31 drives the gripper 33 to rotate, thereby fixing the pump casing. After the processing mechanism 4 is placed in the preset position, the rotary driver 35 drives the inner ring of the slewing bearing 34 to rotate, so that the pump casing rotates slowly and uniformly, thereby continuously changing the processing position of the pump casing.

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

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

[0057] In one embodiment of this application, such as Figure 6 As shown, multiple spiral grooves 51 are provided on the outer wall of the grinding roller 434.

[0058] Understandably, setting multiple spiral grooves 51 that rotate towards the ground can guide the metal particles after grinding, thereby preventing the metal particles from splashing randomly and ensuring the safety of factory production.

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

[0060] Understandably, the collection box 61 is designed to collect metal particles, thus facilitating their unified processing.

[0061] In summary, the submersible pump casing processing device of this application, by setting the grinding assembly into a quadrilateral structure, allows the two grinding rollers to simultaneously contact the pump casing under the linkage of the first hydraulic telescoping device, the connecting block, and the connecting rod. The rotating clamping mechanism can fix the pump casing and drive it to rotate at a uniform speed. This 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 subjected to uniform force during the grinding process, thereby preventing the pump casing from detaching from the device.
