[0034] like Figures 1 to 8 As shown, the present invention provides a stainless steel pipe grinding device, including a base 1, and also including:

[0035] A vertical plate 4, which is fixedly connected to the top outer wall of the base 1;

[0040] The above scheme is adopted: two groups of vertical plates 4 are provided, each group of vertical plates 4 has two opposite vertical plates, and a group of adjustment components 3 are correspondingly provided on the outer wall of each group of vertical plates 4. A grinding roller 9 is provided between one group of vertical plates 4 through a connecting rod 307, and a threaded rod 205 is provided between the other group of vertical plates 4 through a connecting rod 307; the grinding roller 9 can be driven to rotate continuously through the driving mechanism 2 to grind the stainless steel pipe body 8 fixed in the clamping mechanism 6, and the driving object of the motor 201 can also be adjusted through the adjustment component 3 to drive the threaded rod 205 to rotate; the dust suction mechanism 5 can suck and collect metal debris generated during the grinding process, and there is no need for the operator to manually clean it.

[0041] like Figures 2 to 5 As shown, the outer wall of the rotating shaft 301 is fixedly connected to the first transmission wheel 202, the outer wall of the first transmission wheel 202 is connected to the second transmission wheel 204 through the transmission belt 203, the outer wall of the connecting rod 307 is fixedly connected to the threaded rod 205, the outer wall of the threaded rod 205 is threadedly connected to the moving block 206, the outer wall of the vertical plate 4 is fixedly connected to the guide rod 207, and the outer wall of the guide rod 207 is slidably connected to the bottom plate 208; the motor 201 is fixedly connected to the outer wall of the vertical plate 4, the second transmission wheel 204 is fixedly connected to the outer wall of the rotating shaft 301, and the bottom plate 208 is slidably connected to the top outer wall of the base 1.

[0042] The above scheme is adopted: the first transmission wheel 202 is fixed to the outer wall of the rotating shaft 301 of one group of adjusting components 3, and the second transmission wheel 204 is fixed to the outer wall of the rotating shaft 301 of another group of adjusting components 3. When the motor 201 drives one group of adjusting components 3 to rotate, the second transmission wheel 204 can be driven to rotate synchronously through the transmission effect of the first transmission wheel 202 and the transmission belt; the first transmission wheel 202 and the corresponding adjusting component 3 can drive the grinding roller 9 to rotate to grind the tube body 8, and when the second transmission wheel 204 and the corresponding adjusting component 3 rotate, the threaded rod 205 can be driven to rotate and the moving block 206 can be moved. Since the moving block 206 and the bottom plate 208 are both fixed to the outer wall of the dust suction mechanism 5, the dust suction mechanism 5 can be guided by the guide rod 207 to move back and forth horizontally to suck and recycle the metal debris dropped from the base 1.

[0043] like Figures 3 to 5 As shown, the rotating shaft 301 is fixedly connected to the output shaft of the motor 201, the inner wall of the rotating shaft 301 is elastically connected with a block 303 through a connecting spring 302, the inner wall of the moving rod 304 is fixedly connected with a protrusion 306, the outer wall of the moving rod 304 is provided with a slot 305, and the outer wall of the connecting rod 307 is provided with a groove 308; one end of the connecting spring 302 is fixedly connected to the outer wall of the block 303, and the other end of the connecting spring 302 is fixedly connected to the inner wall of the rotating shaft 301, the block 303 is slidably connected to the inner wall of the rotating shaft 301, the block 303 is engaged with the slot 305, and the protrusion 306 is engaged with the groove 308.

[0044] The above scheme is adopted: one group of rotating shafts 301 is fixed on the output shaft of the motor 201, and the rotating shafts 301 in another group of adjusting components 3 are rotatably connected to the corresponding vertical plates 4, and the moving rod 304 can move laterally on the outer wall of the rotating shaft 301. By adjusting the connection state between the moving rod 304 and the connecting rod 307, the adjusting component 3 can drive the grinding roller 9 or the threaded rod 205 to rotate; the outer wall of the moving rod 304 is provided with two groups of card grooves 305. Under normal conditions, the connecting spring 302 drives the card block 303 to engage with a group of card grooves 305 to fix the moving rod 304; when the moving rod 304 moves to the point where the protrusion 306 engages with the groove 308, and the card block 303 engages with the moving rod 304, the moving rod 304 is fixed. When the movable rod 304 is limited, the rotating shaft 301 and the movable rod 304 can drive the connecting rod 307 to rotate synchronously; when the movable rod 304 moves to the point where the protrusion 306 is out of contact with the groove 308, the rotating shaft 301 and the movable rod 304 cannot drive the connecting rod 307 to rotate. Therefore, by adjusting the position of the movable rod 304, the motor 201 can drive the grinding roller 9 or the threaded rod 205 to rotate separately when it is started, thereby ensuring that the threaded rod 205 and the dust suction mechanism 5 remain stationary during the grinding process, ensuring the stability and continuity of the grinding, and avoiding interference factors such as vibration and displacement caused by the movement of the threaded rod 205 and the dust suction mechanism 5, thereby improving the grinding quality.

[0045] like Figure 6 As shown, the collection box 501 is fixedly connected to the top outer wall of the base plate 208, and the outer wall of the pressure plate 505 is hinged with a handle 502 through a hinge rod 503; the two ends of the hinge rod 503 are respectively hinged to the handle 502 and the outer wall of the pressure plate 505, one end of the return spring 504 is fixedly connected to the outer wall of the pressure plate 505, and the other end of the return spring 504 is fixedly connected to the inner wall of the collection box 501, and the outer wall of the pressure plate 505 is slidably connected to the inner wall of the collection box 501.

[0046] The above scheme is adopted: the dust collector head 506 is the existing technology, which can suck the metal debris on the base 1 into the collection box 501 for collection; the pressure plate 505 is always on one side of the collection box 501 under the action of the reset spring 504, and the handle 502 is always on the top in this state; when the handle 502 is pressed down, one end of the hinged rod 503 can be driven to flip downward, and the end fixed to the pressure plate 505 can be flipped upward, driving the pressure plate 505 to move laterally, stretching the reset spring 504, so that the debris in the collection box 501 can be squeezed by the pressure plate 505, reducing the space it occupies, and collecting more debris; after compression, the reset spring 504 drives the pressure plate 505 to move in the opposite direction and reset due to the elastic force, thereby reducing the frequency of the operator cleaning the debris inside the collection box 501 and reducing the work intensity.

[0047] like Figure 7 and Figure 8As shown, the top outer wall of the base 1 is fixedly connected to the movable seat 7, the fixed plate 601 is fixedly connected to the outer wall of the movable seat 7, the inner wall of the fixed plate 601 is rotatably connected to the turntable 603, the outer wall of the turntable 603 is provided with an inclined groove 604, the inner wall of the inclined groove 604 is provided with a slide bar 606, the outer wall of the slide bar 606 is fixedly connected to a clamping block 605, the outer wall of the turntable 603 is fixedly connected to a rotating rod 607, the outer wall of the rotating rod 607 is provided with a slot 608, and the outer wall of the fixed plate 601 is elastically connected to the plug block 602 via a telescopic spring 609.

[0048] The above scheme is adopted: the movable seat 7 is composed of an electric slide rail, which can drive the clamping mechanism 6 to move, so that the tube body 8 is moved to fit with the grinding roller 9 for grinding; the outer wall of the fixed plate 601 is provided with two groups of horizontal guide grooves, and the slide rod 606 passes through the guide grooves. When the turntable 603 rotates, the inclined groove 604 will squeeze the slide rod 606 to make it move. Under the action of the guide grooves, the two groups of slide rods 606 will drive the corresponding clamping blocks 605 to move to the middle or both sides at the same time, so as to clamp and fix the tube body 8 of different diameters, which has high adaptability and is convenient and quick to operate.

[0049] like Figure 8 As shown, the slide rod 606 passes through the outer wall of the fixed plate 601, one end of the telescopic spring 609 is fixedly connected to the outer wall of the plug block 602, and the other end of the telescopic spring 609 is fixedly connected to the outer wall of the fixed plate 601; the plug block 602 is slidably connected to the outer wall of the fixed plate 601, the plug block 602 is clamped in the slot 608, and the tube body 8 is in contact with the outer wall of the clamp block 605.

[0050] The above scheme is adopted: multiple groups of slots 608 are provided, and under normal conditions, the telescopic spring 609 drives the plug 602 to pop out due to its own elastic force and engage with a group of slots 608, thereby fixing the rotating rod 607 and the rotating disk 603, and keeping the two groups of clamps 605 fixed; when it is necessary to rotate the rotating rod 607 to adjust the position of the clamp 605, the plug 602 can be pulled upward to make it disengage from the slot 608, so as to release the limit of the rotating rod 607 and rotate it.

[0051] The working principle and use process of the present invention:

[0052] The operator can first place the stainless steel pipe body 8 to be polished on the clamping mechanism 6 on the base 1, pull the plug block 602 on the outer wall of the fixed plate 601 to make it disengage from the slot 608 on the outer wall of the rotating rod 607, rotate the rotating rod 607, drive the turntable 603 to rotate, and the inclined groove 604 on the outer wall of the rotating rod 603 squeezes the sliding rod 606. Under the action of the guide groove of the fixed plate 601, the sliding rod 606 drives the clamping block 605 to move. When the clamping block 605 is adjusted to fit the outer wall of the pipe body 8, the plug block 602 is released. Under the action of the telescopic spring 609, the plug block 602 is engaged with the slot 608, and the rotating rod 607 and the rotating disk 603 are fixed to complete the clamping and fixation of the pipe body 8.

[0053] At this time, the clamping mechanism 6 can be moved to the tube body 8 and the grinding roller 9 through the movable seat 7, and the block 303 in the adjustment component 3 corresponding to the motor 201 is pressed to release the limit of the moving rod 304 and move it, so that the protrusion 306 is engaged with the groove 308 on the outer wall of the connecting rod 307, and then the moving rod 304 is limited by the block 303 and the groove 305, and then the block 303 in another group of adjustment components 3 is pressed to move the corresponding moving rod 304 so that it is out of contact with the connecting rod 307, and then the motor 201 can be started, and the corresponding group of rotating shafts 301 and the moving rod 304 drive the connecting rod 307 to rotate synchronously, thereby driving the grinding roller 9 to rotate, and grinding the stainless steel tube body 8 fixed in the clamping mechanism 6.

[0054] After grinding is completed, the block 303 in the adjustment component 3 corresponding to the threaded rod 205 can be pressed to push the corresponding moving rod 304 to move, the protrusion 306 is engaged with the groove 308, and the moving rod 304 in the other set of adjusting components 3 is disengaged from the connecting rod 307. When the motor 201 is started, it cannot drive the grinding roller 9 to rotate, but can only drive the threaded rod 205 to rotate, so that the moving block 206 moves laterally under the guidance of the guide rod 207, and the dust collection mechanism 5 moves back and forth laterally, and the dust collection head 506 sucks the metal debris dropped from the base 1 into the collection box 501 for collection.

[0055] When a certain amount of debris is collected in the collection box 501, the handle 502 can be pressed down, and the handle 502 drives the pressure plate 505 to move horizontally through the hinge rod 503, stretching the reset spring 504, and the pressure plate 505 squeezes the debris in the collection box 501 to reduce the space occupied by the debris; after the squeezing is completed, the handle 502 is released, and the reset spring 504 drives the pressure plate 505 to move in the opposite direction and reset due to the elastic force, which can reduce the space occupied by the debris in the collection box 501, improve the space utilization rate in the collection box 501, reduce the frequency of operators cleaning the collection box 501, and reduce the work intensity.
