[0013] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0014] 1. In the present invention, first, a tubular metal part is placed above the multiple rollers. The laser instrument operates to emit a laser line. The two dual-axis motors operate synchronously to drive the multiple third threaded rods to rotate synchronously. The multiple third threaded rods rotate to drive the multiple T-shaped blocks to move, so that the two T-shaped blocks arranged on both sides of the same cross plate move in opposite directions or move closer to each other. The multiple T-shaped blocks move to drive the multiple connecting plates to move. The multiple connecting plates move to drive the multiple support rods to move. The multiple support rods move to drive the multiple long plates to rotate. The multiple long plates rotate to drive the multiple rollers to move in an arc shape, so that the two rollers arranged above the same cross plate expand or approach. The multiple rollers move to drive the tubular metal part to move up or down. When the central axis of the tubular metal part coincides with the laser line emitted by the laser instrument, the two dual-axis motors are stopped from operating;

[0015] The third motor operates to drive the second threaded rod to rotate. The second threaded rod rotates to drive the two cross plates to move inside the cross slots, so that the tubular metal part moves towards the fixing component. When all the multiple support columns are completely inside the tubular metal part, the third motor can be stopped from operating, thereby adjusting the position of the tubular metal part and making the central axis of the tubular metal part coincide with the central axis of the fixing component;

[0016] Through the cooperation of the above structures, the third threaded rod, the T-shaped block, the connecting plate and the support rod can drive the roller to move, and can drive the tubular metal part to move up and down, ensuring that the central axis of the tubular metal part is at the center of the fixing component. The second threaded rod and the cross plate can move the tubular metal part horizontally, facilitating the adjustment of the position of the tubular metal part.

[0017] 2. In the present invention, multiple support columns are initially completely located inside the tubular metal part through the support assembly. The second electric telescopic rod operates to drive the cylinder to move, and the movement of the cylinder drives the movement of multiple first hinge plates and second hinge plates, so that the multiple support columns move outward. The multiple support columns cooperate with multiple anti-slip strips on their surfaces to firmly support the inner wall surface of the tubular metal part, thereby firmly supporting and fixing the tubular metal part;

[0018] The first electric telescopic rod operates to drive the U-shaped frame to move downward. The first motor operates to drive the grinding roller to rotate. The movement of the U-shaped frame drives the grinding roller to move downward. The grinding roller contacts the outer surface of the tubular metal part for grinding treatment. The first motor operates to drive the grinding roller to move horizontally. The second motor operates to drive the rotating rod to rotate. The rotation of the rotating rod drives the gear to rotate. The gear and the toothed ring mesh with each other, so that the hollow column rotates. The rotation of the hollow column drives the rotation of multiple support columns, and together with multiple rollers, the tubular metal part rotates, so as to comprehensively grind the outer surface of the tubular metal part;

[0019] Through the cooperation of the above structures, multiple support columns support and fix the inner wall of the tubular metal part, and the fixed tubular metal part can rotate, which is convenient for comprehensively grinding the outer surface of the tubular metal part without repeatedly adjusting the position of fixing the tubular metal part, improving the practicability of the device.

[0041] In one embodiment, the support assembly 9 includes a cross slot 901, which is opened through the top surface of the workbench 1.

[0043] In one embodiment, L-shaped support plates 905 are fixedly installed on both side surfaces of the two cross plates 904, dual-axis motors 906 are fixedly installed at the centers of the top surfaces of the two cross plates 904, and third threaded rods 907 are fixedly installed on multiple output ends of the two dual-axis motors 906.

[0044] Specifically, Figure 8 As shown: the two dual-axis motors 906 are both forward and reverse rotating motors, which play a role in driving the plurality of third threaded rods 907 to rotate forward and reverse, and the T-block 909 moves stably with the help of the third threaded rods 907 and the slide groove 908.

[0045] In one embodiment, two long plates 911 are hinged at both ends of the top surfaces of two cross plates 904. Every two of the multiple long plates 911 form a group.

[0046] Specifically, as Figure 8 shown: The multiple rollers 912 play a role in assisting the rotation of the tubular metal part. When the multiple T-shaped blocks 909 move to the extreme ends of both ends of the corresponding third threaded rods 907, during this process, the multiple connecting plates 910 will not always maintain a vertical state. The multiple connecting plates 910 cooperate with the multiple support rods 913 to drive the multiple rollers 912 to move in an arc.

[0047] Working principle:

[0048] When using this grinding device for metal parts, first place the tubular metal part on the upper sides of the multiple rollers 912 and ensure that the center point of the tubular metal part is at the center position of every two of the multiple rollers 912. Subsequently, operate the laser instrument 803 and two dual-axis motors 906 through the control terminal 3. The laser instrument 803 operates to emit a laser line. The two dual-axis motors 906 operate synchronously to drive the multiple third threaded rods 907 to rotate synchronously. The multiple third threaded rods 907 rotate to drive the multiple T-shaped blocks 909 to move, so that the two T-shaped blocks 909 arranged on both sides of the same cross plate 904 move in opposite directions or move closer to each other. The movement of the multiple T-shaped blocks 909 drives the multiple connecting plates 910 to move. The movement of the multiple connecting plates 910 drives the multiple support rods 913 to move. The movement of the multiple support rods 913 drives the multiple long plates 911 to rotate. The rotation of the multiple long plates 911 drives the multiple rollers 912 to move in an arc, so that the two rollers 912 arranged above the same cross plate 904 expand or approach each other. The movement of the multiple rollers drives the tubular metal part to move up or down. When the central axis of the tubular metal part coincides with the laser line emitted by the laser instrument 803, stop operating the two dual-axis motors 906 through the control terminal 3, so that the tubular metal part is located at the center position of the fixing component 8;

[0049] At this time, the third motor 903 is operated through the control terminal 3. The operation of the third motor 903 drives the second threaded rod 902 to rotate. The rotation of the second threaded rod 902 drives the two cross plates 904 to move inside the cross groove 901, so that the tubular metal part moves towards the fixing component 8. When all the support columns 805 are completely inside the tubular metal part, the operation of the third motor 903 can be stopped, thereby adjusting the position of the tubular metal part and making the central axis of the tubular metal part coincide with the central axis of the fixing component 8, which is convenient for fixing the tubular metal part;

[0050] Through the cooperation of the above structures, the third threaded rod 907, the T-shaped block 909, and the connecting plate 910 cooperate with the support rod 913 to drive the roller 912 to move, which can drive the tubular metal part to move up and down, ensuring that the central axis of the tubular metal part is at the center of the fixing component 8. The second threaded rod 902 cooperates with the cross plate 904 to be able to move the tubular metal part horizontally, which is convenient for adjusting the position of the tubular metal part;

[0051] When it is necessary to completely polish the outer surface of the tubular metal part, first, through the support component 9, all the support columns 805 are completely inside the tubular metal part. Subsequently, the second electric telescopic rod 801 is operated through the control terminal 3. The operation of the second electric telescopic rod 801 drives the cylinder 802 to move. The movement of the cylinder 802 drives the movement of multiple first hinge plates 804 and second hinge plates 806, so that multiple support columns 805 move outward. The multiple support columns 805 cooperate with multiple anti-slip strips on their surfaces to firmly support the inner wall surface of the tubular metal part, thereby firmly supporting and fixing the tubular metal part;

[0052] At this time, the first electric telescopic rod 607 and the first motor 403 are operated through the control terminal 3. The operation of the first electric telescopic rod 607 drives the U-shaped frame 604 to move downward. The operation of the first motor 403 drives the polishing roller 605 to rotate. The movement of the U-shaped frame 604 drives the polishing roller 605 to move downward. The polishing roller 605 contacts the outer surface of the tubular metal part for polishing treatment. Subsequently, the second motor 704606 and the first motor 403 are operated through the control terminal 3. The operation of the first motor 403 drives the polishing roller 605 to move horizontally. The operation of the second motor 704606 drives the rotating rod 702 to rotate. The rotation of the rotating rod 702 drives the gear 703 to rotate. The gear 703 and the toothed ring 709 mesh with each other, so that the hollow column 707 rotates. The rotation of the hollow column 707 drives the rotation of multiple support columns 805, and cooperates with multiple rollers 912 to make the tubular metal part rotate, so as to comprehensively polish the outer surface of the tubular metal part;

[0053] Through the cooperation of the above structures, multiple support columns 805 support and fix the inner wall of the tubular metal part, and the fixed tubular metal part can rotate, which is convenient for comprehensively grinding the outer surface of the tubular metal part without repeatedly adjusting the position of fixing the tubular metal part, thus improving the practicability of the device.

[0054] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
