As shown in fig. 1 to 6, the present embodiment provides a pipe cover chamfering machine for machining a round of chamfer on a pipe cover 100. The pipe cover chamfering machine comprises a frame, wherein the frame comprises a vertical frame and a mounting seat board 11 fixedly arranged on the rear side of the vertical frame, a feeding channel and a feeding channel which are mutually communicated are formed in front of the mounting seat board 11, the feeding channel is horizontally arranged, the feeding channel is provided with a feeding starting position and a chamfering processing position, the feeding starting position is positioned at the joint of the feeding channel, the chamfering processing position is positioned on one lateral side of the feeding starting position, in particular, the chamfering processing position of the embodiment is positioned on the right side of the feeding starting position, and in other examples, the chamfering processing position can also be positioned on the left side of the feeding starting position. The feeding channel is provided with a waiting position near the joint of the feeding channel and the feeding channel, and when the pipe cover 100 is fed and chamfering processed, the next pipe cover 100 is positioned at the waiting position to wait for the next period of processing.
Regarding the construction of the feeding channel and the feeding channel, specifically, the mounting seat plate 11 is fixedly provided with the fixed back plate 13 through the middle rod, the upper part of the rear side of the stand is fixedly provided with the fixed groove rail 12 through the middle piece and positioned in front of the fixed back plate 13, the front side of the stand is fixedly provided with the fixed front plate 14 through the middle pipe and positioned in front of the fixed back plate 13, the left end of the fixed front plate 14 also extends upwards to be positioned in front of the fixed groove rail 12, the feeding channel is formed between the fixed back plate 13 and the fixed front plate 14, and the feeding channel is formed between the fixed front plate 14 and the fixed groove rail 12.
The fixed slot rail 12 is in a U-shaped slot structure, preferably the fixed slot rail 12 is vertically arranged, the pipe cover 100 slides into the feeding start position from the dead weight of the feeding channel and is transversely pushed to the chamfering processing position, in fact, the fixed slot rail 12 is in a U-shaped slot structure, so that the left end of the fixed front plate 14 extends upwards, on one hand, the fixed front plate 14 can be matched with the fixed slot rail 12 to form the feeding channel, and on the other hand, the fixed front plate 14 can be used for preventing the pipe cover 100 from falling out from the opening side of the fixed slot rail 12. In addition, in order to facilitate the placement of the tube cover 100 into the loading channel, the upper end of the fixed front plate 14 and the upper end of the fixed slot rail 12 are both opened outwards to form an inlet. It is noted that in other examples the fixed rail 12 may be provided obliquely.
In order to push the pipe cover 100 from the feeding position to the chamfering position, a feeding unit is arranged on the pipe cover chamfering machine, and the feeding unit comprises, but is not limited to, a structure that two sliding rails are fixedly arranged on the mounting seat plate 11 at intervals up and down in the embodiment, sliding blocks are slidingly matched on the sliding rails, a sliding plate 21 is fixedly arranged between the two sliding blocks, a push plate 22 is fixedly arranged on the front side of the right end of the sliding plate 21, the left side of the sliding plate 21 is connected with a piston rod of a traversing cylinder 24 (in other examples, the traversing cylinder 24 can be replaced by other types of driving mechanisms such as a motor chain transmission system, and the like), and the push plate 22 and the sliding plate 21 are both positioned between the fixed front plate 14 and the fixed back plate 13 and driven by the traversing cylinder 24 to transversely reciprocate along the sliding rails. The upper and lower ends of the front side of the push plate 22 are respectively provided with a first rolling body 31 through a first fixed shaft, the first rolling bodies 31 are specifically deep groove ball bearings (in other examples, the first rolling bodies 31 can also be rolling wheels which are arranged on the first fixed shaft through bearings), the first rolling bodies 31 are positioned between the push plate 22 and the fixed back plate 13 and positioned in a feeding channel, when the push plate 22 moves leftwards through a feeding start position, the first rolling bodies 31 are positioned leftwards through the feeding start position, and a space is reserved for the pipe cover 100 to slide into the feeding start position of the feeding channel from the dead weight of the waiting position of the feeding channel, and then the right-hand movement of the traversing cylinder 24 drives the push plate 22 to move rightwards, so that the pipe cover 100 can be pushed by the first rolling bodies 31 until the chamfering processing position.
In order to ensure that the pipe cover 100 is not blocked in the feeding process from the feeding start position to the chamfering processing position, the width of the feeding channel is larger than the axial width of the pipe cover 100, the guiding surface of the fixed back plate 13, namely the front side surface of the fixed back plate is an upright surface parallel to the transverse moving direction of the sliding plate 21, the front side surface of the fixed back plate 13 is not protruded forward relative to the bottom surface of the tail end groove of the fixed back plate 12, in this embodiment, the front side surface of the fixed back plate 13 and the bottom surface of the tail end groove of the fixed back plate 12 are on the same upright surface, in addition, the upper end of the right side of the sliding plate 21 is provided with a supporting part matched with the circumferential surface of the pipe cover 100 in an arc line, and the upper end of the left side of the fixed back plate 13 is higher than the supporting part of the sliding plate 21, so that when the pipe cover 100 is in the waiting position, the pipe cover 100 is attached to the upper end of the right side of the sliding plate 21 and matched with the left and right limiting surfaces of the fixed back plate 12, the left side of the fixed back plate 13 is inserted upward into the waiting position to be positioned behind the pipe cover 100, and when the left side of the sliding plate 21 loses the support of the pipe cover 100, and the supporting part of the pipe cover 21 is fixed on the lower side of the back plate 100, and the pipe cover 100 is only fixed in the front of the pipe cover 100.
Furthermore, in order to prevent the tube cover 100 from directly falling down into the feeding channel from the gap between the front side of the slide plate 21 and the first rolling bodies 31 during the left movement of the slide plate 21, the distance between the first rolling bodies 31 and the slide plate 21 in this embodiment is smaller than the diameter of the tube cover 100 and/or the space distance between the push plate 22 and the fixed back plate 13 is larger than the width of the circumferential surface of the tube cover 100. Because the first rolling bodies 31 rotate, the first rolling bodies 31 can roll and fit with the circumferential surface of the pipe cover 100 in the process of moving leftwards along with the push plate 22, movement interference or lateral movement obstacle cannot be caused, and when the first rolling bodies 31 move to the left side of the feeding start position, the self weight of the pipe cover 100 falls into the feeding start position.
In order to prevent the pipe cover 100 from falling down to the feeding channel from the fixed slot rail 12 and then directly falling out of the feeding channel, the bottom of the sliding plate 21 of the embodiment is fixedly provided with a lower supporting plate 23, the lower supporting plate 23 is positioned at the bottom of the feeding channel and between the fixed front plate 14 and the fixed back plate 13, and the lower supporting plate 23 horizontally extends and protrudes rightwards relative to the push plate 22, so that the pipe cover 100 is supported by the lower supporting plate 23 after falling into the feeding channel, and meanwhile, the pipe cover 100 is prevented from falling out of the feeding channel from front to back through the fixed front plate 14 and the fixed back plate 13. The lower supporting plate 23 moves to the chamfering processing station along with the pushing plate 22 pushing to the right, so that the pipe cover 100 is always kept in the feeding channel during pushing.
When the pipe cover 100 is pushed to the chamfering station, the pipe cover 100 is clamped by the clamping unit and the pipe cover 100 is driven to rotate by the rotary driving unit for chamfering. In this embodiment, a mounting vertical plate 15 is fixedly mounted on one side of the mounting seat plate 11 corresponding to the chamfering processing station, and second rolling bodies 32 are mounted on positions of the mounting vertical plate 15 corresponding to the first rolling bodies 31 through second fixing shafts respectively, where the second rolling bodies 32 specifically adopt deep groove ball bearings (in other examples, the second rolling bodies 32 may also be rollers mounted on the second fixing shafts by adopting bearings). When the tube cap 100 is brought into the chamfering processing position, the circumferential surface of the tube cap 100 is in rolling contact with the first rolling element 31 and the second rolling element 32, and the first rolling element 31 and the second rolling element 32 cooperate to hold the X-axis coordinate and the Z-axis coordinate of the rotation center of the tube cap 100. The two first rolling elements 31 and the two second rolling elements 32 are respectively located in four quadrants of the tube cover 100, preferably the two first rolling elements 31 are vertically corresponding, and the two second rolling elements 32 are vertically corresponding.
In addition, since the width of the feeding passage is greater than the axial width of the tube cap 100, the Y-axis coordinate of the rotation center of the tube cap 100 also needs to be uniformly controlled, and a set of rotation supporting members and movable clamping members are provided at both front and rear sides of the chamfering processing station to ensure the Y-axis coordinate.
The movable clamping assembly of the embodiment comprises, but is not limited to, a clamping cylinder 41 and a clamping executing component 42, wherein the clamping cylinder 41 is fixedly installed on a frame, the clamping executing component 42 is rotatably installed at the tail end of a piston rod of the clamping cylinder 41 through a bearing, a through hole is formed in a position, corresponding to the clamping executing component 42, of the fixed front plate 14, the clamping executing component 42 is a hollow cylinder, and the clamping executing component 42 corresponds to the center of a pipe cover 100 and rotates along with the pipe cover 100 in a clamping state. When the pipe cover 100 reaches the chamfering position, the clamping cylinder 41 acts to drive the clamping executing component 42 to push the pipe cover 100 backwards until the specified position is reached, so that Y-axis coordinates of the pipe cover 100 during chamfering can be ensured, and when the pipe cover 100 rotates to chamfer, the clamping executing component 42 is driven to rotate and keep a fitting state.
In order to reduce the rotation resistance to the pipe cover 100, a rotation supporting component is further arranged at the position of the mounting seat plate 11 corresponding to the chamfering processing position, and the supporting surface of the rotation supporting component, which is contacted with the pipe cover 100, protrudes forward by 0-2mm relative to the front side surface of the fixed back plate 13 (including the condition of being flush with the front side surface of the fixed back plate 13), so that the axial B end of the pipe cover 100 is limited and supported by the rotation supporting component or the rotation supporting component and the fixed back plate 13 are jointly limited and supported, and especially, the condition of being limited and supported by the rotation supporting component is converted, so that the rotation resistance can be greatly reduced.
The four groups of rotating support assemblies are obliquely arranged and correspondingly distributed in four quadrant areas of the chamfering processing station. Each of the rotation support assemblies includes two mounting seats 51, a mounting shaft mounted between the two mounting seats 51, and a plurality of third rolling bodies 53 sleeved on the mounting shaft, the third rolling bodies 53 are specifically deep groove ball bearings (in other examples, the third rolling bodies 53 may also be rollers mounted on the mounting shaft by bearings), the third rolling bodies 53 are in rolling fit with the axial B ends of the tube caps 100, and the center of circle (i.e., the rotation center) of the tube caps 100 is projected onto the axis extension line of the mounting shaft, so that even if the third rolling bodies 53 protrude forward relative to the fixed back plate 13, the tube caps 100 are not prevented from being smoothly sent to the chamfering processing station, because the obliquely arranged third rolling bodies 53 smoothly guide the tube caps 100 to the chamfering processing station by rolling around the mounting shaft and the arc-shaped guiding surfaces thereof, and the Y-axis coordinate consistency of the tube caps 100 can be ensured each time.
The first rolling bodies 31, the second rolling bodies 32, as well as the movable clamping assembly and the rotary support assembly together form a clamping unit for the pipe cover 100. The fixed back plate 13 of the present embodiment extends to the chamfering processing station, and the pipe cover 100 is smoothly guided to the rotation support assembly of the chamfering processing station by using the front side surface of the fixed back plate 13.
The rotary driving unit for driving the pipe cover 100 to rotate comprises, but is not limited to, a rotary motor and a driving wheel 61, wherein the driving wheel 61 is coaxially arranged on an output shaft of the rotary motor and is in friction braking with the circumferential surface of the pipe cover 100, the driving wheel 61 and a rotation limiting assembly are arranged in a staggered manner, the rotary motor is started, the friction braking between the driving wheel 61 and the circumferential surface of the pipe cover 100 is performed, the circumferential surface of the pipe cover 100 is circular, and the rotation center is limited by the first rolling body 31, the second rolling body 32, the third rolling body 53 and the clamping executing component 42, so that the rotation processing of the pipe cover 100 is realized.
Regarding chamfering the axial B end of the pipe cap 100, the pipe cap chamfering machine further includes a chamfering unit rotatably mounted on the frame, the chamfering unit rotates to a working position to process a chamfer on the pipe cap 100 when chamfering, and is reversely moved away from the working position after chamfering is completed so that the next pipe cap 100 smoothly enters the chamfering processing position.
The chamfering unit of the embodiment comprises a chamfering motor 73, a chamfering tool bit, a combined seat body 72 and a driving cylinder 71, wherein the cylinder body of the driving cylinder 71 is hinged on the mounting seat plate 11, the tail end of a piston rod of the driving cylinder is hinged with the combined seat body 72, the combined seat body 72 is rotatably mounted on the mounting vertical plate 15 and can turn back and forth around the rotating connection point, the chamfering motor 73 is mounted on the combined seat body 72, the output shaft of the chamfering motor is provided with the chamfering tool bit, and the chamfering tool bit acts on the pipe cover 100 on a chamfering processing station or leaves the chamfering processing station along with the telescopic action of the driving cylinder 71. The combined seat 72 can adjust the vertical and longitudinal positions of the chamfering motor 73.
When chamfering is completed, the rotating motor is stopped, the chamfering motor 73 is stopped, the driving cylinder 71 is reversely operated to retract the chamfering motor 73, the clamping cylinder 41 is retracted again to loosen the pipe cover 100, then the traversing cylinder 24 is retracted to drive the first rolling body 31 to loosen the pipe cover 100, and simultaneously the lower supporting plate 23 is also pulled away from the chamfering processing station, so that the self weight of the pipe cover 100 falls out from the lower part of the chamfering processing station to complete blanking, the pipe cover 100 in the waiting position slides into the feeding starting position in a self weight manner, and then the traversing cylinder 24 is extended to drive the pipe cover 100 in the feeding starting position to the chamfering processing station, and chamfering processing is performed after clamping positioning is completed.
