DETAILED DESCRIPTION

[0031] The technical solutions of the present invention will be described clearly and completely below in conjunction with the drawings in the present invention. In addition, the forms of the various structures described in the following embodiments are merely examples. The burr removal device for cement pipe ports involved in the present invention is not limited to the various structures described in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] like Figure 1-8 As shown, in one embodiment, a burr removal device for a cement pipe port is proposed, comprising a mounting column 1, wherein the mounting column 1 is rotatably connected to a rotating seat 101 on its circumferential surface, a positioning assembly 2 is mounted on the rear end of the rotating seat 101, a mounting disc 102 is rotatably connected to the rotating seat 101 on its circumferential surface, a cleaning assembly 3 is arranged in the mounting disc 102, the cleaning assembly 3 comprises an edge grinding mechanism 31 and a driving mechanism 32, the edge grinding mechanism 31 comprises a slide rod 311, a slide seat 312, a slider 313, an inner grinding block 315 and an outer grinding block 316, multiple groups of slide rods 311 are slidably connected in the mounting disc 102, the slide seats 312 are all mounted on the end faces of the slide rods 311, the sliders 313 are all slidably connected in the slide seats 312, a first spring 314 is mounted between the slider 313 and the slide seat 312, the inner grinding block 315 is mounted on the surface of the slider 313, and the outer grinding block 316 is mounted in the slider 313 via a connecting shaft 317;

[0033] The driving mechanism 32 includes a linkage shaft 321, a cam 322, a protrusion 326, a first support block 323 and a second support block 324. The linkage shaft 321 is rotatably connected in the rotating seat 101. The cam 322 is installed on the circumferential surface of the linkage shaft 321. The protrusion 326 and multiple first support blocks 323 are all installed on the surface of the mounting plate 102. Multiple second support blocks 324 are installed on the surface of the rotating seat 101. A second spring 325 is installed between the first support block 323 and the second support block 324.

[0034] In actual application of the embodiment of the present invention, the positioning assembly 2 of the device is moved into the cement pipe, and then the slide bar 311 is controlled to extend from the mounting plate 102, driving the multiple inner grinding blocks 315 and the outer grinding blocks 316 to move synchronously around to match the socket size of the cement pipe. At this time, the device is pushed into the cement pipe so that the inner grinding blocks 315 and the outer grinding blocks 316 are all fitted on the socket of the cement pipe. At the same time, according to the required clearance, the device is pushed into the cement pipe again. Through the action of the first spring 314, the inner grinding block 315 will be on the slide seat 31 2, and the sliding distance is the margin for cleaning and grinding, and then the positioning component 2 can be controlled to operate, so that the positioning component 2 is expanded in the cement pipe, and the mounting column 1 and the cement pipe are fixed together. At this time, the linkage shaft 321 can be controlled to rotate, and the linkage shaft 321 drives the cam 322 to rotate. When the raised position of the cam 322 contacts the protrusion 326, it will drive the mounting plate 102 to rotate on the circumferential surface of the rotating seat 101. At the same time, the first support block 323, the second support block 324 and the first spring 314 act to rotate the mounting plate 102. The position limit of the disk 102 rotating on the rotating seat 101 makes the mounting disk 102 only rotate slightly on the rotating seat 101, and when the cam 322 pushes the protrusion 326 to drive the mounting disk 102 to rotate, the first spring 314 then drives the mounting disk 102 to reset, thereby achieving the effect of controlling the reciprocating rotation of the mounting disk 102 on the rotating seat 101, and synchronously drives the inner grinding block 315 and the outer grinding block 316 to shake. When the inner grinding block 315 and the outer grinding block 316 shake, they will rub against the local position of the cement pipe port, and at the same time control When the mounting seat rotates on the circumferential surface of the mounting column 1, the inner grinding block 315 and the outer grinding block 316 will be driven to rotate with the mounting column 1 as the center, so that the inner grinding block 315 and the outer grinding block 316 can be controlled to rotate during the shaking process. After one rotation, the burrs on the cement pipe port can be cleaned. At the same time, during the cleaning process, the inner grinding block 315 and the outer grinding block 316 are shaken at a high frequency and rubbed against the cement pipe. When the burrs on the end face of the cement pipe are cleaned by friction, the splashing of the cleaned burrs can be avoided, and the efficiency of burr cleaning can be improved.

[0035] In one case of an embodiment of the present invention, the radians of the grinding surfaces of the inner grinding block 315 and the outer grinding block 316 are opposite to adapt to the inner and outer circular openings of the cement pipe port, and arc transitions are set at both ends of the inner grinding block 315 and the outer grinding block 316. When the inner grinding block 315 and the outer grinding block 316 rotate in a circle, they can achieve the effect of transition with the burrs on the cement pipe port to avoid jamming.

[0036] like Figure 4-6 As shown, in one embodiment, a plurality of linkage rods 4 are rotatably connected in the mounting disk 102, linkage bevel gears 401 are installed on the end faces of the linkage rods 4 and adjacent linkage bevel gears 401 are meshed, gears 402 are installed on the circumferential surfaces of the linkage rods 4, tooth grooves 403 opened on the circumferential surface of the slide rod 311 are meshed with the gears 402, a driving rod 404 is rotatably connected in the mounting disk 102, a first worm 405 is installed on the circumferential surface of the driving rod 404, and the first worm 405 is meshed with a first worm gear 406 installed on the circumferential surface of one of the linkage rods 4.

[0037] When the embodiment of the present invention is actually used, the driving rod 404 is controlled to rotate, and the driving rod 404 drives the first worm 405 to rotate, and the first worm 405 drives the first worm wheel 406 to rotate, and the first worm wheel 406 will drive one of the linkage rods 4 to rotate. When one of the linkage rods 4 rotates, the multiple linkage rods 4 can be rotated synchronously through the action of the linkage bevel gear 401, and then the linkage rod 4 will synchronously drive the gear 402 to rotate, and the gear 402 will drive multiple groups of sliding rods 311 to slide in the mounting plate 102 through the action of the tooth groove 403, thereby realizing the control of the expansion distance of the inner grinding block 315 and the outer grinding block 316 to adapt to cement pipes within a certain size range, and can perform burr cleaning operations on cement pipe ports of different sizes.

[0038] like Figure 6 、 7 As shown in Figures 12 and 13, in one embodiment, a pair of positioning blocks 5 are slidably connected in the slider 313, a third spring 501 is installed between the positioning blocks 5, and a slot 502 provided on the circumferential surface of the connecting shaft 317 engages with the positioning blocks 5.

[0039] During actual application of the embodiment of the present invention, after the connecting shaft 317 on the outer grinding block 316 is inserted into the slider 313, the position of the outer grinding block 316 is adjusted according to the thickness of the cement pipe socket to match the thickness of the cement pipe socket, and then the positioning block 5 is pushed to move by the third spring 501 so that the positioning block 5 is inserted into the slot 502 opened on the circumferential surface of the connecting shaft 317, thereby achieving the effect of fixing the position of the outer grinding block 316, and then the burrs at the cement pipe socket are cleaned. At the same time, when the burrs at the socket of the cement pipe are cleaned, the inner side of the socket is generally cleaned. At this time, the positioning block 5 is pushed inward so that the positioning block 5 is pulled out from the slot 502 opened on the circumferential surface of the connecting shaft 317. At this time, the outer grinding block 316 can be taken out, and then the burrs at the socket of the cement pipe can be cleaned separately by the inner grinding block 315.

[0040] In one case of an embodiment of the present invention, when connecting cement pipes, the socket needs to be inserted into the socket, and the end face of the socket needs to hold the socket. At this time, if there are burrs on the inner and outer sides of the socket of the cement pipe and the inner side of the socket, it will interfere with the precise docking of the cement pipe, resulting in the need for additional processing during the installation process, reducing the installation efficiency. At the same time, the burrs may damage the sealing surface of the pipe port, increase the risk of leakage, and cause negative effects such as affecting the overall sealing of the pipe system. Therefore, when connecting cement pipes, it is necessary to keep the socket and the socket of the cement pipe flat.

[0041] like Figure 8 and 9 As shown, in one embodiment, a dual-axis motor 6 is installed in the rotating seat 101 , and a first drive shaft 601 is installed at one output end of the dual-axis motor 6 . The first drive shaft 601 is connected to the linkage shaft 321 via a first sprocket set 602 .

[0042] When the embodiment of the present invention is actually used, the dual-axis motor 6 is controlled to operate, and the dual-axis motor 6 drives the first drive shaft 601 to rotate. The first drive shaft 601 drives the linkage shaft 321 to rotate through the first sprocket group 602, and the linkage shaft 321 drives the cam 322 to rotate, thereby achieving the effect of controlling the reciprocating rotation of the mounting plate 102 on the rotating seat 101, causing the inner grinding block 315 and the outer grinding block 316 to vibrate at a high frequency.

[0043] like Figure 9 and 10 As shown, in one embodiment, a second worm gear 603 is installed on the circumferential surface of the rotating seat 101, a rotating frame 604 is installed on the surface of the rotating seat 101, a mounting shaft 605 is rotatably connected inside the rotating frame 604, and a second worm 606 installed on the circumferential surface of the mounting shaft 605 is engaged with the second worm gear 603.

[0044] In actual application of the embodiment of the present invention, when the mounting plate 102 rotates back and forth on the rotating base 101, the mounting shaft 605 is controlled to rotate, and the mounting shaft 605 drives the second worm 606 to rotate. Since the mounting column 1 is fixedly connected to the cement pipe through the positioning component 2, and the second worm gear 603 is fixedly connected to the mounting column 1, when the second worm gear 606 rotates, it will not drive the second worm gear 603 to rotate. On the contrary, the force acts on the second worm gear 606, and the rotating base 101 and the mounting column 1 are rotationally connected. The second worm gear 606 is in a fixed state with the rotating base 101 under the action of the mounting shaft 605 and the rotating frame 604. At this time, when the second worm 606 rotates, the rotating seat 101 will rotate on the mounting column 1, thereby achieving the effect of controlling the rotation of the rotating seat 101 relative to the mounting column 1. When the rotating seat 101 rotates, the first support block 323, the second support block 324, the second spring 325, the cam 322 and the protrusion 326 position limit function, so that the mounting plate 102 can only rotate within the moving range on the rotating seat 101, and then the rotation of the rotating seat 101 can drive the mounting plate 102 to rotate, so that the inner grinding block 315 and the outer grinding block 316 rotate with the mounting column 1 as the center when shaking, completing the effect of cleaning the burrs on the circumference of the end face of the cement pipe.

[0045] like Figure 10 As shown, in one embodiment, a second drive shaft 607 is installed at the other output end of the dual-axis motor 6, a first connecting bevel gear 608 is installed on the circumferential surface of the second drive shaft 607, a connecting rod 609 is rotatably connected inside the rotating frame 604, a second connecting bevel gear 6010 installed on the circumferential surface of the connecting rod 609 is meshed with the first connecting bevel gear 608, and the connecting rod 609 and the mounting shaft 605 are connected via a second sprocket set 6011.

[0046] In actual application of the embodiment of the present invention, when the dual-axis motor 6 is running, the second drive shaft 607 rotates, and the second drive shaft 607 drives the first connecting bevel gear 608 to rotate. The first connecting bevel gear 608 drives the connecting rod 609 to rotate through the second connecting bevel gear 6010, and the connecting rod 609 drives the installation shaft 605 to rotate through the second sprocket set 6011, thereby achieving the effect of driving the second worm 606 to rotate.

[0047] like Figure 11 and 12As shown, in one embodiment, the positioning assembly 2 includes a guide frame 201, a connecting frame 202, a support rod 203 and an anti-slip pad 205. The guide frame 201 is installed at the rear end of the rotating seat 101, a pair of connecting frames 202 are slidably connected on the circumference of the guide frame 201, multiple groups of support rods 203 are rotatably connected in the connecting frame 202, and each group of support rods 203 is rotatably connected to the positioning seat 204 at one end away from the connecting frame 202. The anti-slip pads 205 are all installed on the surface of the positioning seat 204. The bidirectional threaded rod 206 rotatably connected to the guide frame 201 and the rotating seat 101 is threadedly connected to the connecting frame 202, and the bidirectional threaded rod 206 is connected to the output end of the positioning motor 207 installed in the rotating seat 101.

[0048] When the embodiment of the present invention is actually applied, the positioning motor 207 is controlled to operate, and the positioning motor 207 drives the bidirectional threaded rod 206 to rotate, and the bidirectional threaded rod 206 drives the guide frame 201 to move forward and backward. Through the action of the support rod 203, the positioning seat 204 is driven to expand to the four sides, so that the anti-slip pad 205 installed on the surface of the positioning seat 204 fits tightly with the inner wall of the cement pipe, thereby achieving the effect of fixing the installation column 1 to the cement pipe. When the burrs on the current end face of the cement pipe are cleaned, the positioning motor 207 is controlled to reverse, and the positioning seat 204 can be controlled to shrink inward, so as to achieve the effect of removing the equipment from the cement pipe.

[0049] like Figure 1 As shown, in one embodiment, a housing 7 is mounted on the surface of the rotating seat 101 , and a control handle 701 is mounted on the surface of the housing 7 .

[0050] In actual application of the embodiment of the present invention, when the device is used to deburr the end face of a cement pipe, the device can be moved by holding the control handle 701, thereby improving the flexibility of the device when used.
