[0014] Preferably, two second cylinders are symmetrically connected to the bracket, and output ends of the two second cylinders are respectively connected to push plates.

[0015] A method for chamfering and grinding a continuous casting crystallizer copper tube comprises the following steps:

[0016] Place the copper tube to be polished on the workbench, control the extension of the two second cylinders, push the copper tube to be polished to the center of the square plate in the horizontal direction, and then adjust the height of the vertical plate so that the copper tube to be polished is at the center of the square plate in the vertical direction;

At this time, the hinged parts of the connecting rods that are close to each other drive the two oppositely arranged grinding discs to approach each other through the mounting seat. After the two grinding discs contact the end of the copper tube, the driving shaft drives the square plate to rotate at its center, so that the grinding disc rotates and grinds the end of the copper tube to chamfer. When the end of the square copper tube is chamfered, the two opposite corners of the two connecting rods forming a rectangle are successively The two groups of symmetrically arranged grinding discs approach each other in turn, and after the two grinding discs in the vertical direction contact the rectangular copper tube, the driving shaft drives the square plate to move back and forth horizontally, so that the two grinding discs in the vertical direction chamfer the upper and lower sides of the port of the rectangular copper tube.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Reference Figure 1-Figure 7 , this embodiment provides a technical solution: a chamfering and grinding device for a copper tube of a continuous casting crystallizer, comprising a workbench 1, a vertically movable vertical plate 3 is connected to the workbench 1, a driving shaft 38 is rotatably connected to the vertical plate 3, a square plate 2 is installed at the end of the driving shaft 38, the driving shaft 38 can drive the square plate 2 to rotate and slide horizontally and vertically, the connection part between the driving shaft 38 and the square plate 2 is at the center of the square plate 2, a central rod 21 is connected to a side of the square plate 2 away from the driving shaft 38, four telescopic rods 22 are connected to the central rod 21 in a circular array, the ends of two adjacent telescopic rods 22 are hinged with connecting rods 23, the first ends of the four connecting rods 23 are hinged in sequence and enclosed into a rectangle, and the four hinged parts are respectively located at four At the end of the telescopic rod 22, four mounting seats 24 are slidably connected on the square plate 2, and the four mounting seats 24 are respectively connected to the ends of the four telescopic rods 22; grinding discs 25 are connected to the four corners of the rectangle enclosed by the four connecting rods 23. When two diagonal angles in the rectangle enclosed by the four connecting rods 23 approach each other, the other two diagonal angles move away from each other, so that two of the grinding discs 25 approach each other, and the other two grinding discs 25 move away from each other. At this time, the vertical plate 3 rotates, and the grinding disc 25 can chamfer the circular copper tube, and after the two grinding discs 25 in the vertical direction approach each other, the vertical plate 3 moves back and forth horizontally, and then, after the two grinding discs 25 in the horizontal direction approach each other, the vertical plate 3 moves back and forth vertically, and at this time, the grinding disc 25 can chamfer the rectangular copper tube.

[0032] When in use, the copper tube to be polished is placed on the workbench 1, and the position of the workbench 1 is adjusted so that the end of the copper tube is located in the middle of the square plate 2. When the end of the circular copper tube is chamfered, any two opposite corners of the four connecting rods 23 enclosing a rectangle are close to each other, and the other opposite corners are far away from each other. At this time, the hinged parts of the connecting rods 23 close to each other drive the two oppositely arranged polishing discs 25 to approach each other through the mounting seat 24. After the two polishing discs 25 contact the ends of the copper tube, the driving shaft 38 drives the square plate 2 to rotate with its center, so that the polishing disc 25 rotates and polishes the ends of the copper tube to chamfer.

[0033] When chamfering the end of the square copper tube, the two groups of opposite corners of the two connecting rods 23 enclosing the rectangle are approached to each other in turn, so that the two groups of symmetrically arranged grinding discs 25 are approached to each other in turn. After the two grinding discs 25 in the vertical direction contact the rectangular copper tube, the driving shaft 38 drives the square plate 2 to move back and forth horizontally, so that the two grinding discs 25 in the vertical direction chamfer the upper and lower sides of the port of the rectangular copper tube. After the two grinding discs 25 in the horizontal direction approach each other and contact the rectangular tube, the driving shaft 38 drives the square plate 2 to move back and forth in the vertical direction, so that the two grinding discs 25 in the horizontal direction chamfer the left and right sides of the port of the rectangular copper tube, so that the device can adapt to the chamfering operation at the ports of round copper tubes and square copper tubes;

[0034] The arrangement of the telescopic rod 22 and the mounting seat 24 ensures that the rectangle enclosed by the connecting rod 23 will not rotate relative to the central rod 21, thereby ensuring that the two sets of relatively arranged grinding discs 25 can stably approach or move away from each other. A motor is connected to the mounting seat 24, and the grinding disc 25 is connected to the output end of the motor. The grinding disc 25 is driven by the motor to rotate.

[0035] The side of the square plate 2 is connected with an electric push rod 26, which is connected to the mounting seat 24 on the same side. When the electric push rod 26 is extended or retracted, it can drive the two mounting seats 24 arranged opposite to each other to move closer to or farther from each other.

[0036] When the electric push rod 26 is extended or retracted, it can push the mounting seat 24 connected thereto to slide in a straight line, thereby driving the rectangle formed by the four connecting rods 23 to deform, so that the two relatively arranged grinding discs 25 can move closer to or farther away from each other. A pressure sensor is set at the connection between the electric push rod 26 and the mounting seat 24. The pressure value obtained by the pressure sensor is used to determine whether the grinding disc 25 is in contact with the copper pipe to be polished. Moreover, when adjusting the position of the grinding disc 25, the grinding disc 25 is not in a rotating state at this time, ensuring that the interference received by the pressure sensor when obtaining the pressure value is reduced.

[0037] Four limit rods 31 are arranged in a circular array on the vertical plate 3, and the two limit rods 31 arranged opposite to each other are extended and retracted synchronously, and the two limit rods 31 in the vertical direction can abut against the upper and lower sides of the square plate 2 when extended, and the square plate 2 can move laterally at this time, and the two limit rods 31 in the horizontal direction can abut against the left and right sides of the square plate 2 when extended, and the square plate 2 can move longitudinally at this time.

[0038] The driving shaft 38 is driven by an external servo motor to ensure the accuracy of the rotation angle of the square plate 2. If the square plate 2 needs to slide to chamfer the end of the rectangular copper tube, two sets of limit rods 31 are relatively set to extend and retract respectively, so that the upper and lower sides and the left and right sides of the square plate 2 are clamped respectively. When the upper and lower sides of the square plate 2 are clamped, the square plate 2 can only slide in the left and right directions. When the left and right sides of the square plate 2 are clamped, the square plate 2 can only slide in the up and down directions, thereby limiting the sliding direction of the square plate 2.

[0039] The square plate 2 is symmetrically slidably connected to two first racks 36 in the horizontal direction and symmetrically slidably connected to two second racks 37 in the vertical direction. The driving shaft 38 is connected to a first toothless gear 361 meshing with the two first racks 36 and a second toothless gear 371 meshing with the two second racks 37. When the two limit rods 31 in the horizontal direction abut against the upper and lower sides of the square plate 2, the two first racks 36 in the horizontal direction approach each other and mesh with the first toothless gear 361, so that the driving shaft 38 drives the square plate 2 to reciprocate vertically. Moreover, when the two limit rods 31 in the vertical direction abut against the upper and lower sides of the square plate 2, the two second racks 37 in the vertical direction approach each other and mesh with the second toothless gear 371, so that the driving shaft 38 drives the square plate 2 to reciprocate horizontally.

[0040] When the rectangular copper tube is chamfered, two limit rods 31 symmetrical in the vertical direction are extended, and at the same time, the two grinding discs 25 in the vertical direction approach each other and contact the upper and lower sides of the square copper tube, thereby limiting the vertical movement direction of the square plate 2. At this time, the two second racks 37 in the vertical direction approach each other and are located at a position capable of meshing with the second toothless gear 371. At this time, the second toothless gear 371 is driven to rotate by the driving shaft 38 and alternately meshes with the upper and lower second racks 37, thereby enabling the square plate 2 to reciprocate in the horizontal direction. At this time, the two grinding discs 25 in the vertical direction grind the upper and lower sides of the rectangular copper tube.

[0041] Two horizontally symmetrical limit rods 31 are extended, and at the same time, the two horizontal grinding discs 25 approach each other and contact the left and right sides of the copper tube, limiting the horizontal movement direction of the square plate 2. At this time, the two horizontal first racks 36 approach each other and are located in a position that can engage with the first toothless gear 361, so that the left and right sides of the rectangular copper tube can be polished subsequently.

[0042] A synchronization rod 34 is slidably connected to the middle part of the square plate 2. The synchronization rod 34 can be inserted into or pulled out of the drive shaft 38 when sliding axially. When the synchronization rod 34 is inserted into the drive shaft 38, the square plate 2 is locked to the drive shaft 38, and when the synchronization rod 34 is pulled out of the drive shaft 38, the square plate 2 is unlocked from the drive shaft 38.

[0043] A protrusion is provided at the end of the synchronization rod 34, and a recessed portion cooperating with the protrusion is provided on the square plate 2. When the synchronization rod 34 is extended so that the protrusion is stuck in the recessed portion, the driving shaft 38 can drive the square plate 2 to rotate through the synchronization rod 34. At this time, the end of the circular copper tube can be chamfered. When the synchronization rod 34 pulls out the driving shaft 38, the end of the synchronization rod 34 sinks under the surface of the square plate 2. At this time, the square plate 2 can be radially displaced relative to the driving shaft 38, and then the movement of the square plate 2 can chamfer the end of the directional copper tube.

[0044] A slide 32 is slidably connected inside the square plate 2, a synchronization rod 34 is connected to the middle of the slide 32, and wedges 33 are connected to the four sides of the slide 32. The two first racks 36 or the two second racks 37 can be squeezed on the wedge 33 when they are close to each other so that the synchronization rod 34 can pull out the drive shaft 38.

[0045] The slide 32 slides in the square plate 2 and can only slide in the axial direction of the drive shaft 38 and will not rotate relative to the square plate 2, ensuring that the drive shaft 38 can drive the square plate 2 to rotate through the synchronization rod 34 connected to the slide 32. When the two first racks 36 or the two second racks 37 approach each other, they can respectively squeeze the wedge blocks 33 on the same side to make the slide 32 slide away from the drive shaft 38, so that the synchronization rod 34 connected to the slide 32 can be separated from the contact with the drive shaft 38, ensuring that the subsequent horizontal or vertical sliding of the square plate 2 is not interfered with.

[0046] A spring 35 is connected between a surface of the slide seat 32 away from the synchronization rod 34 and the square plate 2 .

[0047] When the two first racks 36 or the two second racks 37 move away from each other, they can be out of contact with the wedge block 33 on the same side. At this time, the wedge block 33 is no longer squeezed, so that the spring 35 pushes the slide 32 to reset, so that the subsequent synchronization rod 34 can be inserted into the drive shaft 38.

[0048] The timing for the two first racks 36 or the two second racks 37 to move away from each other is when the square plate 2 reciprocates once and continues to move, so that the drive shaft 38 and the synchronization rod 34 are in a coaxial position, ensuring that the subsequent synchronization rod 34 can be stably inserted into the drive shaft 38 to complete the locking of the square plate 2.

[0049] A bracket 11 is connected to the workbench 1, and a first cylinder 12 is connected to the bracket 11. A pressure plate 13 is connected to the output end of the first cylinder 12. A plurality of detection rods 14 arranged in a linear array are slidably connected through the pressure plate 13. A tension spring 15 is connected between the top of the detection rod 14 and the upper surface of the pressure plate 13. The copper tube to be polished is inserted into the lower part of the pressure plate 13. When the copper tube to be polished is circular, after the pressure plate 13 is pressed down, the plurality of detection rods 14 slide unequal distances relative to the pressure plate 13. When the copper tube to be polished is rectangular, the plurality of detection rods 14 slide equal distances relative to the pressure plate 13. When the plurality of detection rods 14 slide equal distances, the two sets of limit rods 31 arranged relatively to each other extend and retract in sequence. Moreover, when the sliding distances of the plurality of detection rods 14 are unequal, the two sets of limit rods 31 do not extend or retract.

[0050] The copper tube to be polished passes through the middle part of the bracket 11, and then the first cylinder 12 is controlled to extend, so that the pressure plate 13 moves down and presses on the copper tube to be polished. If the copper tube to be polished is rectangular, multiple detection rods 14 contact the nearest single side of the copper tube to be polished, so that the multiple detection rods 14 slide equidistantly. If the copper tube to be polished is circular, multiple detection rods 14 contact the circular side wall of the copper tube to be polished, so that the multiple detection rods 14 slide unequally, and the sliding distances of the detection rods 14 symmetrical to the two sides of the copper tube to be polished are equal, and displacement sensors are arranged on the tops of the multiple detection rods 14. If the displacement values ​​obtained by the multiple displacement sensors are equal, the control system controls the equipment to operate according to the above-mentioned action of chamfering the rectangular copper tube. If the displacement values ​​obtained by the multiple displacement sensors are unequal, the control system controls the equipment to operate according to the above-mentioned action of chamfering the circular copper tube.

[0051] Two second cylinders 16 are symmetrically connected to the bracket 11 , and output ends of the two second cylinders 16 are respectively connected to push plates 17 .

[0052] When adjusting the relative position of the square plate 2 and the copper tube to be polished, the two second cylinders 16 are controlled to extend synchronously by an equal distance, so that the copper tube to be polished is pushed to the middle of the square plate 2 in the horizontal direction. Subsequently, the first cylinder 12 is controlled to extend, and then the vertical plate 3 is controlled to move vertically, so that the copper tube to be polished is in the middle of the square plate 2 in the vertical direction, ensuring that the two relatively arranged polishing discs 25 can contact the end of the copper tube to be polished when they are synchronously approached. After the chamfering of the end of the copper tube is completed, the two second cylinders 16 and the first cylinder 12 are controlled to shorten, and the copper tube can be taken out.

[0053] A method for chamfering and grinding a continuous casting crystallizer copper tube comprises the following steps:

[0054] Place the copper tube to be polished on the workbench 1, control the extension of the two second cylinders 16 to push the copper tube to the center of the square plate 2 in the horizontal direction, and then adjust the height of the vertical plate 3 so that the copper tube to be polished is at the center of the square plate 2 in the vertical direction;

[0055] The first cylinder 12 is controlled to extend. If the copper tube to be polished is rectangular, the multiple detection rods 14 contact the nearest single side of the copper tube to be polished, so that the multiple detection rods 14 slide at equal distances. If the copper tube to be polished is circular, the multiple detection rods 14 contact the circular side wall of the copper tube to be polished, so that the multiple detection rods 14 slide at unequal distances, and the detection rods 14 symmetrical to the two sides of the copper tube to be polished slide at equal distances.

[0056] When the copper tube to be polished is round, the two sets of limit rods 31 do not extend or retract, and the two sets of first racks 36 and the two sets of second racks 37 do not slide. At this time, the electric push rod 26 extends or shortens, so that the two relatively arranged polishing discs 25 approach each other and contact the end of the copper tube to be polished, and then the driving shaft 38 drives the square plate 2 to rotate to complete the chamfering of the end of the round copper tube;

[0057] When the copper tube to be polished is square, the two groups of limit rods 31 are extended and retracted respectively, and the square plate 2 is limited horizontally and vertically in turn. After the two limit rods 31 in the horizontal direction are extended, the two first racks 36 approach each other, so that the drive shaft 38 is unlocked from the square plate 2, so that the drive shaft 38 drives the square plate 2 to slide back and forth vertically through the first toothless gear 361. Subsequently, the two limit rods 31 in the horizontal direction are retracted, and the two limit rods 31 in the vertical direction are extended, and the two second racks 37 approach each other, so that the drive shaft 38 is unlocked from the square plate 2, so that the drive shaft 38 drives the square plate 2 to slide back and forth horizontally through the second toothless gear 371, thereby completing the chamfering of the end of the rectangular copper tube.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
