DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Embodiment 1: Please refer to the attached drawings, the present invention provides a technical solution: A gear pump body finishing device includes a workbench 100, a loading and unloading assembly is provided on the top front side of the workbench 100, a processing groove 500 is provided in the middle of the top, and a movable positioning mechanism is provided on the workbench 100 at a position corresponding to the processing groove 500; The mobile positioning mechanism comprises a door-shaped fixed frame 101 symmetrically fixed on both sides of the top of the workbench 100, a moving component is arranged in the fixed frame 101, a motor and a rotating shaft 303 are arranged on the moving component, a rotating frame 302 is fixed to the inner end of the rotating shaft 303, a mounting seat 304 is fixed to the end of the rotating frame 302 away from the rotating shaft 303, a flip shaft 404 is rotatably connected to the mounting seat 304, and a positioning component is commonly fixed between the two flip shafts 404, a switching component is arranged on the flip shaft 404, and a limiting structure is arranged at the rotation connection of the flip shaft 404; A grinding assembly is provided in the middle upper part of the processing tank 500, a driving assembly is provided on the rear side of the processing tank 500, and the driving assembly is correspondingly connected to the switching assembly, a top plate 102 is provided on the rear upper part of the processing tank 500, and the four corners of the bottom of the top plate 102 are fixedly connected to the fixed frame 101 on the corresponding side through vertical rods, and a blowing assembly is provided on the top plate 102, and two vertical first hydraulic telescopic rods 105 are symmetrically provided on the top plate 102, and the bottom ends of the two first hydraulic telescopic rods 105 pass through the top plate 102, and are jointly fixed with a lifting frame for installing the corresponding processing structure.

[0023] When processing the gear pump body, a group of multiple pump bodies are placed on the upper and lower material assembly, and the pump body is moved close to the mobile positioning mechanism through the upper and lower material assembly. Then, the motor drives the rotating shaft 303 and the rotating frame 302 to make the positioning assembly flip around the rotating shaft 303 to the pump body, and multiple pump bodies are located inside the positioning assembly and are clamped and fixed by the positioning assembly to achieve the positioning of the pump body.

[0024] After the pump body is positioned, the motor drives the rotating shaft 303 and the rotating frame 302 to rotate backward, so that the positioning component drives the pump body to rotate backward, and then the moving component drives the positioning component and the pump body and other structures to move backward. During the movement, the bottom end surface of the pump body is polished by the polishing component.

[0025] The moving assembly drives the positioning assembly and the pump body to continue to move to the rear side and is located below the lifting frame. Through the cooperation of the first hydraulic telescopic rod 105 and the lifting frame, the processing structure installed on the lifting frame performs corresponding processing on the top of the pump body. The lifting frame drives the processing structure to move back up and cancels the limit of the flip axis 404 by the limiting structure, and then drives the switching component to move through the driving component, so that the switching component drives the flip axis 404 to rotate, and then the positioning component drives the pump body to rotate and flip it up and down, switching the processing position of the pump body, and then the position of the flip axis 404 and the positioning component and other structures is limited by the limiting structure again, so that the other end of the pump body can be processed through the lifting frame and the processing structure.

[0026] After both ends of the pump body are processed, the moving assembly drives the positioning assembly and the pump body to move forward, and during the forward movement, the bottom of the pump body is polished, so that both ends of the pump body are polished separately before and after flipping, making the polishing more comprehensive.

[0027] When the pump body is close to the loading and unloading assembly, the motor drives the rotating shaft 303 and the rotating frame 302 to rotate, so that the rotating frame 302 drives the positioning assembly and multiple pump bodies to rotate back to the loading and unloading assembly, and the processed pump body is transferred through the loading and unloading assembly and transported to the positioning assembly.

[0028] During the processing, the waste dust on the pump body is cleaned by the blowing component, and the waste is collected through the processing tank 500; a dust suction port and a vacuum cleaner can be set at the bottom of the processing tank 500, so that the dust cleaned can be collected by the vacuum cleaner while the blowing is carried out.

[0029] Among them, the loading and unloading assembly includes a rotating material table 200 located above the front side of the workbench 100, and the top of the rotating material table 200 is symmetrically provided with a placement seat 202 on both sides, and a vertical rotating column 201 is fixed at the center of the rotating material table 200. A lifting platform 210 is connected to the top of the workbench 100 through two second hydraulic telescopic rods 209. The rotating column 201 is rotatably connected to the center of the lifting platform 210, and the bottom end passes through the lifting platform 210. A vertical transmission groove 203 is provided at the center of the rotating column 201, and a plurality of vertical limit slide bars 204 are evenly arranged on the inner side wall of the transmission groove 203 along the circumferential direction. A vertical driving shaft 205 is rotatably connected to the corresponding position on the workbench 100, a first bevel gear 206 is fixed to the bottom end of the driving shaft 205, a second bevel gear 207 is meshed with one side of the first bevel gear 206, the second bevel gear 207 is connected to a motor, the top end of the driving shaft 205 is slidably connected to the transmission groove 203, and a plurality of vertical limiting grooves 208 are evenly arranged on the side wall of the driving shaft 205 along the circumferential direction, and the limiting slide bar 204 is slidably connected to the limiting slide groove 208.

[0030] When loading, a group of multiple pump bodies are placed on the placement seat 202 on the rotating material table 200 away from the workbench 100. Through the drive of the motor and the transmission of the first bevel gear 206 and the second bevel gear 207, the driving shaft 205 drives the rotating column 201 to rotate through the limiting slide groove 208 and the limiting slide bar 204, thereby driving the rotating material table 200 and the pump body to rotate, so that the multiple pump bodies move to the side close to the positioning component, and then the pump body is positioned and transferred through the mobile positioning mechanism; When the processing is completed and the pump body returns to the rotating material table 200, the positioning of the pump body is cancelled, and then the lifting platform 210 drives the rotating column 201 and the rotating material table 200 to move downward through the second hydraulic telescopic rod 209, so that the position of the pump body and the positioning component and other structures are staggered, and rotated to the front side for unloading. At the same time, the pump body on the front side placement seat 202 of the rotating material table 200 is rotated to the positioning component for loading and positioning, and the loading and unloading of the pump body are carried out simultaneously, thereby improving the processing efficiency.

[0031] Among them, the positioning component includes a rectangular positioning frame 400 fixed between the ends of two flip axes 404, two positioning seats 401 are symmetrically arranged in the positioning frame 400, and multiple V-shaped positioning grooves 403 are evenly arranged on the opposite sides of the two positioning seats 401, and the other side of the positioning seat 401 is connected to the corresponding side wall of the positioning frame 400 through a third hydraulic telescopic rod 402.

[0032] When the positioning frame 400 moves to the pump body of the loading and unloading assembly, a group of multiple pump bodies are located in the positioning frame 400 and between the two positioning seats 401. The two positioning seats 401 are brought close to each other through the third hydraulic telescopic rod 402, so that the two ends of the corresponding pump body are respectively clamped through the positioning grooves 403 on both sides, thereby realizing the positioning of the pump body and making the pump body located in the middle of the positioning frame 400, which is convenient for subsequent processing and transfer.

[0033] Among them, the switching component includes two rotating circular plates 405 which are arranged in parallel and rotatably connected to the flip shaft 404, and a rotating ring gear 406 is fixed between the two rotating circular plates 405. The outer ring side wall of the rotating ring gear 406 is evenly provided with teeth, and the inner ring side wall is provided with an inner ratchet groove 407. A pawl 408 is rotatably connected to the position of the flip shaft 404 corresponding to the inner ratchet groove 407. The pawl 408 is correspondingly connected to the inner ratchet groove 407, and one side of the pawl 408 is connected to the flip shaft 404 through a spring.

[0034] When it is necessary to flip the flip shaft 404 and the positioning assembly and switch the upper and lower positions, the limit structure on the flip shaft 404 is canceled, and the rotating ring gear 406 is driven to rotate by the driving assembly. At this time, the end of the pawl 408 is stuck on the inner ratchet groove 407, so that when the rotating ring gear 406 rotates, the rotating ring gear 406 drives the flip shaft 404 to rotate through the action of the inner ratchet groove 407 and the pawl 408, thereby realizing the position flipping and switching of the positioning assembly and the pump body; when the driving assembly returns, the rotating ring gear 406 and the inner ratchet groove 407 rotate in the opposite direction, and the inner ratchet groove 407 and the pawl 408 can only drive the flip shaft 404 to rotate in one direction. Therefore, when the inner ratchet groove 407 rotates in the opposite direction, it will not drive the flip shaft 404 to rotate, so that the driving assembly can return to the position without affecting the structures such as the flip shaft 404 and the positioning assembly.

[0035] Among them, the driving component includes a sliding seat 507 symmetrically fixed on both sides of the processing groove 500, and a moving rack 600 is slidably connected in the sliding seat 507, and both ends of the moving rack 600 extend out of the sliding seat 507, and a moving plate 601 is fixed to the rear ends of the two moving racks 600. The front side of the moving plate 601 is connected to the rear end of the processing groove 500 through a spring, and an adjustment platform 603 is provided in the middle of the bottom of the moving plate 601. Push wheels 602 are symmetrically arranged and rotatably connected on both sides of the top of the adjusting platform 603. The moving plate 601 is located between the two pushing wheels 602, and an adjustment shaft 604 is fixed in the middle of the bottom of the adjusting platform 603. A rotating cross bar 605 is rotatably connected to the adjusting shaft 604. A rotating vertical rod 606 is fixed to the bottom of the rotating cross bar 605 close to the processing groove 500. The rotating vertical rod 606 is rotatably connected to the workbench 100, and a motor is connected to the bottom.

[0036] When the positioning assembly and other structures move to the rear section of the processing groove 500, the bottom of the rotating gear ring 406 contacts the movable rack 600. When it is necessary to switch the position of the flip axis 404 and the positioning assembly, the rotating vertical rod 606 is driven by the motor to drive the rotating cross rod 605 to rotate forward, thereby driving the adjustment table 603 and other structures to move, and driving the movable plate 601 to move forward through the pushing wheel 602, thereby realizing the movement of the movable plate 601 and the movable rack 600 and the flipping of the positioning assembly; when the movable rack 600 needs to return to its original position, the rotating cross rod 605 continues to rotate and moves toward the rear side, thereby driving the movable plate 601 to move back to its original position toward the rear side through the pushing wheel 602 and other structures.

[0037] During the movement of the rotating crossbar 605 , the adjustment platform 603 and the adjustment shaft 604 can rotate relative to the rotating crossbar 605 to automatically adjust the positions of the driving wheels 602 so that the two driving wheels 602 are always located at the front and rear sides of the moving plate 601 .

[0038] Among them, the limiting structure includes limiting grooves 409 symmetrically arranged on the upper and lower sides of the flip axis 404, and spring grooves 305 are provided at the positions corresponding to the two limiting grooves 409 inside the mounting seat 304. A spring block 306 is connected to the spring groove 305 through a spring, and the outer end of the spring block 306 extends into the corresponding limiting groove 409, and the inner end of the spring block 306 and the inner end of the spring groove 305 are respectively provided with an electromagnet 307, and the electromagnet 307 is electrically connected to a power supply and a switch.

[0039] When the positions of the positioning assembly and the rotating frame 302 remain fixed, the position of the flip shaft 404 is limited by the mounting seat 304 and the spring block 306 to prevent the flip shaft 404 from rotating; when the switching assembly contacts the driving assembly and the flip shaft 404 is required to drive the positioning assembly to rotate and switch the position, the electromagnet 307 is energized to attract each other, so that the spring block 306 retracts into the spring groove 305 and disengages from the limiting groove 409, so that the driving assembly can drive the switching assembly and the flip shaft 404 to rotate; after flipping, the electromagnet 307 is powered off, and the spring block 306 moves outward again under the action of the spring and extends into the limiting groove 409, thereby limiting the position of the flip shaft 404 again.

[0040] Embodiment 2: The structure of this embodiment is basically the same as that of embodiment 1, except that the grinding assembly includes support frames 501 symmetrically fixed on both sides of the processing groove 500, a grinding roller 502 is rotatably connected to the middle of the top of the two support frames 501, cleaning rollers 503 are symmetrically arranged on both sides of the grinding roller 502, and the cleaning rollers 503 are rotatably connected to the support frames 501, one end of the grinding roller 502 is connected to a motor, and the other end is fixed with a first gear 504, and one end of the cleaning roller 503 is fixed with a second gear 505, and the first gear 504 and the second gear 505 are all rotatably connected to the same support frame 501, and a third gear 506 is meshed between the first gear 504 and the second gear 505, and the third gear 506 is rotatably connected to the support frame 501. The cleaning roller 503 and the grinding roller 502 are rotated by the drive of the motor and the transmission of the first gear 504, the second gear 505 and the third gear 506, so that when the pump body passes through the grinding assembly, the pump body is polished by the grinding roller 502, and the waste dust and the like adhering to the pump body are cleaned by the bristles on the cleaning roller 503.

[0041] Embodiment 3: The structure of this embodiment is basically the same as that of embodiment 1, except that the spray assembly includes a fan 103 fixed to one side of the top plate 102, and air ducts 104 are respectively connected to both sides of the fan 103, and the two air ducts 104 are fixed in parallel to the top surface of the top plate 102, and a plurality of air outlets are evenly fixed at the bottom of the air duct 104, and the bottom end of the air outlet passes through the top plate 102. When grinding and other processing are performed, the pump body is sprayed and cleaned by the fan 103 and the air duct 104 to prevent waste dust from adhering to the pump body and affecting subsequent processing.
