Detailed Description
The present invention will be described in detail below with reference to specific embodiments shown in the drawings. These embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to these embodiments are included in the scope of the present invention.
In the various illustrations of the present invention, certain dimensions of structures or portions are exaggerated relative to other structures or portions for ease of illustration and, thus, are merely provided to illustrate the basic structure of the subject matter of the present invention.
The invention provides a pipeline end surface grinding device which is used for grinding an end surface of a pipeline cut by a pipe cutting machine so as to remove burrs on the end surface of the pipeline and polish the end surface of the pipeline.
As shown in fig. 1, 2, 6, 7, 8 and 9, the pipe end surface grinding apparatus includes a supporting device 10, a dust removing device 20 and a grinding device 30.
The support device 10 comprises a support mechanism 11 for supporting the pipeline. The grinding device 30 includes a grinding head 31 for grinding the end surface of the pipeline, and the grinding head 31 removes burrs from the end surface of the pipeline and polishes the end surface of the pipeline by grinding the end surface of the pipeline.
As shown in fig. 3, the dust removing device 20 includes a blowing mechanism 21, the blowing mechanism 21 includes a blowing member 211, and a guide member 212 disposed between the blowing member 211 and the support mechanism 11, and the blowing member 211 has a blowing port facing the guide member 212.
As shown in fig. 5, a guide groove 2121 recessed in a direction away from the blowing element 211 is provided on a side of the flow guide element 212 facing the blowing element 211, and a diameter of the guide groove 2121 decreases in the direction away from the blowing element 211, so that the gas guided by the guide groove 2121 flows obliquely outward as shown in fig. 5, and it is ensured that a circumference of the end surface of the pipe can be blown with the gas. The flow guide element 212 is adapted to the inner diameter of the pipe.
The pipe is supported by the support mechanism 11 and the flow guide element 212 is passed through the opening of the pipe into the interior of the pipe. In the process that the polishing head 31 polishes the end face of the pipeline, the blowing element 211 blows air towards the flow guide element 212, and the blown air flows outwards from the interior of the pipeline under the flow guide effect of the flow guide element 212, so that the debris on the end face of the pipeline is blown outwards from the pipeline, and the debris is effectively prevented from entering the interior of the pipeline. The deflector element 212 may also act as a sealing plug, preventing debris from continuing to migrate deeper into the conduit, even if some debris enters the conduit. After sanding is complete, the deflector element 212 carries away from the pipe very little debris that has entered the pipe during removal from the pipe interior.
In the present invention, the longitudinal direction of the pipe supported by the support mechanism 11 is defined as the left-right direction, and the horizontal direction perpendicular to the longitudinal direction of the pipe is defined as the front-rear direction.
As shown in fig. 1 and 2, in an embodiment of the present invention, the pipe end surface grinding apparatus further includes a feeding rail 40, a first rail 50, and a positioning device 60. The feeding rail 40 is used to transfer the pipe cut by the pipe cutting machine to the supporting device 10, the first rail 50 is used to guide the movement of the supporting mechanism 11, and the positioning device 60 is used to position one end of the pipe.
As a further improvement of an embodiment of the present invention, a plurality of supporting mechanisms 11 are arranged in the left-right direction, and the stability of the pipeline is improved by the plurality of supporting mechanisms 11. The support mechanism 11 is mounted on the first rail 50 and is slidable in the left-right direction with respect to the first rail 50, thereby allowing the support device 10 to accommodate pipes of different lengths.
As shown in fig. 2 and 3, the supporting mechanism 11 includes a movement driving motor 111, a column 112, a supporting base 113, a supporting shaft 114, a pressing shaft 115, and a lifting driving element 116, the movement driving motor 111 is mounted on the column 112, an axial direction of an output shaft of the movement driving motor 111 is a vertical direction, and an end portion of the output shaft of the movement driving motor 111 is provided with a first gear. The first rail 50 has a rack 51 and a slide rail 52 extending in the left-right direction, the first gear is engaged with the rack 51, and the pillar 112 is slidably mounted on the slide rail 52. When the output shaft of the movement driving motor 111 rotates to rotate the gears synchronously, the column 112 is moved in the left-right direction by the mutual engagement of the first gear and the rack 51, and the support mechanism 11 is moved in the left-right direction.
The support base 113 is mounted on the top end of the upright 112. The two support shafts 114 are arranged along the front-back direction, the axial direction of the support shafts 114 is the left-right direction, and the two support shafts 114 are matched with each other to support the pipeline together. The support shaft 114 is pivotally mounted to the support base 113. The conduit placed on the support shafts 114 is tangent to both support shafts 114, and the central axis of the conduit longitudinally corresponds to the midpoint of the gap between the two support shafts 114. Therefore, the position of the pipe in the front and back direction of the invention is determined under the action of the two support shafts 114, the diversion element 212 can enter the pipe only by moving the pipe or the diversion element 212 in the left and right direction, the pipe or the diversion element 212 does not need to move back and forth, the operation of matching the pipe and the diversion element 212 is simpler, a device for driving the pipe or the diversion element 212 to move back and forth is omitted, and the structure is simplified.
The two pressing shafts 115 are located above the supporting shaft 114, the two pressing shafts 115 are arranged in the front-rear direction, and the axial direction of the pressing shafts 115 is the left-right direction. The lifting driving element 116 drives the pressing shaft 115 to move up and down. When the distance between the pressing shaft 115 and the supporting shaft 114 is large, the pipe cut by the pipe cutting machine can enter the supporting mechanism 11 through the feeding rail 40, and the pipe on the supporting mechanism 11 can be positioned by the positioning device 60. When the positioning is completed, the lifting driving element 116 drives the pressing shafts 115 to move downwards, and the two pressing shafts 115 and the two supporting shafts 114 cooperate to fix the pipeline, preventing the pipeline from moving in the left-right direction.
Further, as shown in fig. 1 and 2, the supporting device 10 further includes a rotating mechanism 12 for driving the supporting shaft 114 of the at least one supporting mechanism 11 to rotate axially. The axial rotation of the support shaft 114 according to the present invention means that the support shaft 114 rotates about its central axis as a rotation axis.
During the process of polishing the pipeline by the polishing head 31, the rotating mechanism 12 drives the supporting shaft 114 to rotate, and the supporting shaft 114 rotates the pipeline on the supporting mechanism 11, so that the polishing head 31 can polish one circle of the end surface of the pipeline. Since the air blowing mechanism 21 is located at the end of the pipeline, if the way of driving the polishing head 31 to move so as to make it surround the end face of the pipeline by one turn is adopted, the polishing head 31 is easily interfered with the air blowing structure when moving, and is easy to hit the air blowing mechanism 21 or block the air blowing of the air blowing element 211, but the invention can prevent the polishing head 31 from interfering with the air blowing mechanism 21 by rotating the pipeline so that the polishing head 31 polishes the end face of the pipeline.
As shown in fig. 2 and 4, the rotating mechanism 12 includes a housing 121, a rotating driving element 122, a second gear 123, a third gear 124 and a fourth gear 125, an output shaft of the rotating driving element 122 is connected to the second gear 123, the third gear 124 is mounted at one end of one support shaft 114, the fourth gear 125 is mounted at one end of the other support shaft 114, and the second gear 123 is located between the third gear 124 and the fourth gear 125 and is meshed with both the third gear 124 and the fourth gear 125. The rotary drive element 122, the second gear 123, the third gear 124 and the fourth gear 125 are all within the housing 121.
When the output shaft of the rotation driving element 122 rotates, the second gear 123 drives the third gear 124 and the fourth gear 125 to rotate, and the third gear 124 and the fourth gear 125 are respectively installed at one end of the two supporting shafts 114, so as to drive the two supporting shafts 114 to rotate, and the rotation directions are the same, so as to drive the pipes on the supporting shafts 114 to rotate. The same direction of rotation of the support shafts 114 as described herein means that both of the support shafts 114 rotate clockwise or both of them rotate counterclockwise. The rotary drive element 122 is preferably an electric motor.
Further, the lifting driving element 116 is a cylinder. The pressing shaft 115 is rotatable about its central axis. The rotatable pressing shaft 115 and the supporting shaft 114 reduce friction against the pipe while the pipe is rotated, preventing damage to the surface of the pipe.
As a further modification of an embodiment of the present invention, as shown in fig. 3, the feeding rail 40 extends in the front-rear direction. The feeding rail 40 has a receiving groove 42 corresponding to a gap between the two support shafts 114, a feeding portion 41 and a stopper portion 43 located at both sides of the receiving groove 42 in the front-rear direction. The infeed section 41 is for conveying pipe cut through the pipe cutter and the receiving slot 42 is for receiving pipe on the support mechanism 11. To prevent the pipe dropped from the feeding portion 41 onto the supporting shaft 114 from rolling out of the supporting mechanism 11 along the arc-shaped surface of the supporting shaft 114, the stopper portion 43 protrudes upward from the supporting shaft 114, and the rolling of the pipe is restricted by the stopper portion 43.
Further, the feeding portion 41 is disposed obliquely, and one end of the feeding portion 41 away from the containing groove 42 is higher than one end connected to the containing groove 42. The pipe on the feeding portion 41 can automatically roll along the feeding portion 41 by gravity.
As shown in fig. 1 and 2, as a further modification of the embodiment of the present invention, the positioning device 60 is located on a first side in the left-right direction of the supporting device 10. The positioning device 60 includes a positioning portion 61 and a positioning drive member 62. The positioning portion 61 is used for abutting against the end of the pipeline, and the positioning driving element 62 is used for driving the positioning portion 61 to move in the up-down direction. The positioning process of the pipe on the support mechanism 11 is as follows: the initial position of the pressure shaft 115 is positioned above the pipeline, and the initial position of the positioning part 61 is positioned below the pipeline; the positioning part 61 moves upwards under the driving of the positioning driving element 62 until the height of the positioning part corresponds to the height of the pipeline, the supporting mechanism 11 moves left and right, the pipeline on the supporting mechanism 11 is driven to move towards the positioning part 61 until the pipeline is contacted with the positioning part 61, and the positioning of the end part of the pipeline is completed.
After the positioning is completed, the supporting mechanism 11 near the positioning device 60 may continue to move toward the positioning device 60 if it is farther from the end of the pipe, and then the pressing shaft 115 of the supporting mechanism 11 near the positioning device 60 moves downward to fix the pipe. After the support mechanism 11, which is away from the positioning device 60, is moved left and right to a position near the other end of the pipe, the pressing shaft 115 thereof is moved downward again to fix the pipe. Like this, two supporting mechanism 11 can support the pipeline and be close to the region at both ends, prevent that the pipeline from rocking at terminal surface in-process both ends of polishing.
Specifically, the positioning drive element 62 is a pneumatic cylinder.
As a further improvement of the embodiment of the present invention, two dust removing devices 20 are distributed in the left-right direction, and the supporting device 10 is located between the two dust removing devices 20. The two dust removing devices 20 are used for removing the scraps at the two ends of the pipeline respectively.
The positioning device 60 is disposed between the supporting device 10 and the dust removing device 20 located at a first side in the left-right direction of the supporting device 10. After the positioning is completed, the positioning device 60 moves downwards to expose the end of the pipeline to the dust removing device 20, and a device for driving the positioning device 60 to move left and right is not needed, so that the structure is simplified.
As shown in fig. 2, the dust removing device 20 further includes a driving mechanism 22 for driving the air blowing mechanism 21 to move in the left-right direction toward or away from the support mechanism 11 and to move up and down. Specifically, the driving mechanism 22 includes a first driving member 221 for driving the air blowing mechanism 21 to move left and right and a second driving member 222 for driving the air blowing mechanism 21 to move up and down. The first driving member 221 drives the blowing mechanism 21 to move left and right to make the guide member 212 enter or leave the duct. When the outer diameters of the pipes are different and the heights of the central axes of the pipes are different, the second driving member 222 drives the guide member 212 to move up and down such that the center of the guide member 212 corresponds to the central axis of the pipe.
Further, the dust removing device 20 further includes at least two air blowing mechanisms 21 distributed in the up-down direction. The deflector elements 212 of different blowing mechanisms 21 are of different sizes. The width of the flow guiding element 212 needs to match the inner diameter of the pipeline, and the dust removing device 20 is suitable for pipelines with different inner diameters by arranging a plurality of air blowing mechanisms 21.
Under the combined action of the positioning device 60 and the two movable supporting mechanisms 11, the distance of the two ends of the pipeline protruding out of the supporting mechanisms 11 can be controlled. In this case, in the preferred embodiment of the present invention, the driving mechanism 22 of the dust removing device 20 located on the first side in the left-right direction of the supporting device 10 is connected to the side of the positioning driving element 62 away from the supporting device 10, and the driving mechanism 22 of the dust removing device 20 located on the second side in the left-right direction of the supporting device 10 is connected to the supporting mechanism 11.
Wherein, the first side and the second side in the left-right direction of the invention specifically mean: the first side is the left side, and the second side is the right side; or the first side is the right side and the second side is the left side.
The dust removing device 20 installed on the supporting mechanism 11 can move left and right synchronously along with the supporting mechanism 11, and a device for driving the dust removing device 20 to move along the first track 50 does not need to be arranged, so that the cost is reduced. No matter how the length of the pipeline changes, the position of the end of the pipeline facing the positioning device 60 is determined in the left-right direction after the end is positioned by the positioning device 60, and the driving mechanism 22 positioned at the first side of the left-right direction of the supporting device 10 is installed on the positioning device 60, and the driving mechanism 22 drives the guide element 212 to move left and right to enable the distance of the stroke of the guide element 212 entering the pipeline to be constant, so that the stroke distance of the first driving element 221 does not need to be adjusted.
As shown in fig. 2 and 3, the dust removing device 20 further includes a cantilever 23 connecting the driving mechanism 22 and the air blowing mechanism 21, the cantilever 23 protrudes the second driving member 222 toward the supporting device 10, and the air blowing mechanism 21 is mounted on the cantilever 23. The provision of the cantilever 23 prevents the second drive member 222 from interfering with the engagement of the insufflation mechanism 21 with the tube by the support mechanism 11 or the positioning device 60.
As shown in fig. 3, as a further improvement of an embodiment of the present invention, the air blowing mechanism 21 further includes a fixing member 213 disposed on a side of the air blowing member 211 away from the flow guide member 212, and a connecting portion 214 connecting the fixing member 213 and the flow guide member 212, wherein the air blowing member 211 is mounted on the fixing member 213, and a gap for avoiding the polishing head 31 is provided between the fixing member 213 and the flow guide member 212.
The cantilever 23 has a hole for engaging with the fixing member 213. The fixing member 213 is provided with a hole therein, which is communicated with the air blowing member 211, and one end of the fixing member 213, which is away from the air guiding member 212, is provided with a connector for connecting with an external air source.
The blowing opening of the blowing member 211 corresponds to the center of the guide groove 2121 so that the gas reflected by the guide groove 2121 flows uniformly as much as possible.
The air blowing element 211 is an air pipe protruding out of the fixing member 213, and when the flow guiding element 212 enters the interior of the pipe, the air blowing opening of the air blowing element 211 can also enter the pipe, so as to prevent the air blown by the air blowing element 211 from affecting the debris blown out of the pipe by the air reflected by the flow guiding element 212 on the one hand, and prevent the air outlet of the air blowing element 211 from being blocked by the debris on the other hand.
To reduce the influence of the connecting portion 214 on the gas flow, the connecting portion 214 is a rod.
Further, the polishing device 30 is located at one side of the front-rear direction of the air blowing member 211, and the connection portion 214 is located at the other side of the front-rear direction of the air blowing member 211. Since the duct has more debris near the side of the polishing device 30, the connection portion 214 is provided at the side of the air blowing member 211 facing away from the polishing device 30, which reduces the influence of the connection portion 214 on dust removal.
The connection of the flow guiding element 212 to the connection 214 is spaced from the edge of the flow guiding element 212, i.e. the projection of the connection 214 onto the flow guiding element 212 does not contact the edge of the flow guiding element 212. Through the technical scheme, on one hand, the connecting part 214 is prevented from contacting with the polishing head 31 as much as possible, and on the other hand, partial chips caused by the fact that the connecting part 214 is too close to the inner wall of the pipeline are prevented from being blown out by gas between the connecting part 214 and the inner wall of the pipeline.
As a further improvement of an embodiment of the present invention, the polishing device 30 includes a second rail 32, two polishing heads 31, and two polishing moving mechanisms 33 for respectively driving the polishing heads 31 to move, wherein the two polishing moving mechanisms 33 are distributed along the left-right direction, and each polishing moving mechanism 33 is provided with a polishing head 31. Under the action of the positioning device 60, the position of one end of the pipeline close to the positioning device 60 is fixed in the left-right direction. The grinding moving mechanism 33 on the same side as the positioning device 60 is fixed relative to the positioning device 60, and the grinding moving mechanism 33 on the side different from the positioning device 60 is mounted on the second rail 32 and moves in the left-right direction on the second rail 32, so that the grinding device 30 can grind the two ends of the pipelines with different lengths, and the structure is simplified.
Further, the polishing moving mechanism 33 includes a mechanical arm and a polishing motor installed at an end of the mechanical arm, the polishing head 31 is connected to an output shaft of the polishing motor, and the polishing head 31 rotates under the action of the polishing motor to polish the end surface of the pipeline.
The concrete working process of the pipeline end surface polishing equipment in the preferred embodiment of the invention is as follows:
(1) the pressing shaft 115 is initially positioned above the pipe, the positioning portion 61 is initially positioned below the pipe, and the pipe falls on the supporting shaft 114 along the feeding portion 41;
(2) the positioning part 61 moves upwards under the driving of the positioning driving element 62 until the height of the positioning part corresponds to the height of the pipeline, the supporting mechanism 11 moves left and right, the pipeline on the supporting mechanism 11 is driven to move towards the positioning part 61 until the pipeline is contacted with the positioning part 61, and the positioning of the end part of the pipeline is completed;
(3) after the positioning is finished, if the supporting mechanism 11 close to the positioning device 60 is far away from the end of the pipeline, the supporting mechanism can continue to move towards the positioning device 60, and then the pressing shaft 115 of the supporting mechanism 11 close to the positioning device 60 moves downwards to fix the pipeline, so that the pipeline is fixed; after the supporting mechanism 11 far away from the positioning device 60 moves left and right to a position close to the other end of the pipeline, the pressing shaft 115 moves downwards again to fix the pipeline;
(4) the positioning part 61 moves downwards to the lower part of the pipeline, the two air blowing mechanisms 21 move to the position of the flow guide element 212 corresponding to the height of the pipeline under the action of the second driving element 222, and then the first driving element 221 drives the air blowing mechanisms 21 to move towards the pipeline until the flow guide element 212 enters the pipeline;
(5) the polishing moving mechanism 33 drives the polishing head 31 to approach the end face of the pipeline, and then the polishing head 31 polishes the end face of the pipeline; at this time, the rotating mechanism 12 drives the supporting shaft 114 to rotate, so that the pipe on the supporting shaft 114 rotates, so that the grinding head 31 can be completely contacted with one circle of the end surface of the pipe, thereby deburring and polishing the whole end surface of the pipe;
(6) during the grinding process, the air blowing element 211 blows air towards the flow guide element 212, and the blown air flows from the interior of the pipeline to the exterior of the pipeline under the flow guide effect of the flow guide element 212, so that the chips on the end surface of the pipeline are blown out of the pipeline;
(7) after the grinding is finished, the grinding moving mechanism 33 drives the grinding head 31 to move away from the pipeline, the first driving element 221 drives the air blowing mechanism 21 to move away from the pipeline until the flow guide element 212 is separated from the pipeline, the pressing shaft 115 moves upwards to remove the fixing effect on the pipeline, and at this time, the pipeline can be taken out of the supporting device 10.
The above-listed detailed description is only a specific description of a possible embodiment of the present invention, and they are not intended to limit the scope of the present invention, and equivalent embodiments or modifications made without departing from the technical spirit of the present invention should be included in the scope of the present invention.
