Referring to fig. 1, fig. 1 shows a specific structure of a circle embracing mechanism 100 according to the present embodiment. The rounding mechanism 100 mainly includes two rounding devices 10, a controller for controlling the rounding devices 10, and two first limit switches 21 and two second limit switches 22 electrically connected to the controller. The two first limit switches 21 are respectively disposed on the two circle holding devices 10, and the two second limit switches 22 are also respectively disposed on the two circle holding devices 10, so as to cooperate together to automatically control the telescopic motion of the circle holding devices 10, thereby replacing the manual control operation.
For convenience of describing the movement process of the positions of the components of the present embodiment, the orientations of "up, down, left and right" appearing hereinafter are based on the view direction of fig. 1.
The two rounding devices 10 are arranged opposite to each other on the left and right sides of the transverse axis of the cylinder 200 so as to jointly surround and extrude the cylinder 200.
Referring to fig. 2, each circle embracing device 10 includes an upright post 11, and an oil cylinder 12, a circle embracing clamping arm 13, a guiding rod 14, a limiting block 15 and a limiting plate 16 on the upright post 11.
The cylinder 12 is used as a driving element to provide a driving force to drive the rounding clamping arm 13 and the guide rod 14 to press the cylinder 200 in the transverse direction together so as to round the cylinder 200. The limiting block 15 is arranged on the guide rod 14 so as to approach the cylinder 200 along with the guide rod 14; the limiting plate 16 is arranged on the circular holding arm 13 to move together.
The column 11 is located laterally beside the barrel 200. The lower end of the upright post 11 is fixedly arranged, and the upper end of the upright post 11 is provided with an oil cylinder 12, a circle holding arm 13, a guide rod 14, a first limit switch 21 and a second limit switch 22.
The cylinder 12 is a hydraulic cylinder 12. The cylinder 12 mainly includes a cylinder body 121 and a telescopic piston rod 122 provided at one end of the cylinder body 121. The cylinder 121 is fixedly disposed on the column 11. The axis of piston rod 122 extends in the lateral direction, i.e., the extending and retracting direction of piston rod 122 coincides with the lateral direction, and piston rod 122 can move laterally closer to or farther from cylinder 200. The controller is electrically connected to the cylinder 12.
The embracing gripping arm 13 is connected with the piston rod 122 of the cylinder 12 to be capable of moving in a lateral direction to approach and squeeze the cylinder 200 by being driven by the piston rod 122.
The embracing circular clamping arm 13 is arc-shaped and is provided with an arc-shaped opening. The opening is directed towards the barrel 200. The circular holding arm 13 is provided with two clamping parts 131; the two clamping portions 131 are respectively disposed at two ends of the opening and are spaced from each other in the vertical direction. The openings of the two laterally embracing clamp arms 13 are opposed so that all the clamp portions 131 can clamp and embrace the cylinder body 200 together.
The guide bar 14 is disposed in the lateral direction. The guide rod 14 is slidably arranged on the upright post 11 in a penetrating manner, and the guide rod 14 is connected with the rounding clamping arm 13 to move transversely along with the rounding clamping arm 13, so that the moving accuracy of the rounding clamping arm 13 is ensured. The guide rod 14 can guide the movement of the rounding clamping arm 13 in the transverse direction, so that the rounding clamping arm 13 is prevented from moving to generate deviation, and the condition that the oil cylinder 12 is damaged due to the deviation is reduced.
The limiting block 15 is arranged at the left end of the guide rod far away from the rounding clamping arm 13 so as to move transversely along with the guide rod. Specifically, the limiting block 15 is rectangular, a through hole penetrates through the middle of the limiting block, and the aperture of the through hole is adapted to the diameter of the guide rod. The limiting block 15 can be sleeved on the guide rod through the through hole to slide along the guide rod. Therefore, the stopper 15 can adjust its relative position on the guide bar.
The first limit switch 21 for sensing the limit block 15 is specifically arranged on the left end surface of the upright post 11, which faces away from the embracing circular clamping arm 13.
The first limit switch 21 has a cylindrical shape. The first limit switch 21 is located above the limit block 15. The probe of the first limit switch 21 for sensing is directed downward toward the limit block 15.
In the present embodiment, the first limit switch 21 is an electro-optical proximity switch. The working principle is as follows: the photoelectric proximity switch can emit light beams, and the existence of a target is detected by utilizing the shielding or reflection of the detected object to the light beams. When the photoelectric proximity switch detects an object, the photoelectric proximity switch is turned on, and then a corresponding detection signal is output to the controller. The detection range of the first limit switch 21 is 10-15 mm, and the limit block 15 is used as a target to be detected.
During the process of pressing the cylinder, the guide rod 14 moves to the right along with the extension of the piston rod 122, and the stopper 15 moves to the right along with the extension. While the first limit switch 21 is stationary. When the limiting block 15 moves to the detection range of the first limiting switch 21, the first limiting switch 21 is triggered, and a detection signal is output to the controller. At this time, as the embracing circular clamping arm 13 synchronously moving with the piston rod 122 contacts and presses the outer wall of the cylinder 200, once the controller receives the detection signal, the controller controls the piston rod 122 of the oil cylinder 12 to stop the rightward extending movement according to the detection signal so as to prevent the excessively extending piston rod 122 from excessively pressing the outer wall of the cylinder 200.
It is appropriate that the controller be able to control the amount of extension of the piston rod 122 by the action of the first limit switch 21, which ensures that the piston rod 122 is able to contact the cylinder 200 and moderately squeeze the cylinder 200.
Of course, the extension amount of the piston rod 122 is proportional to the distance between the stopper 15 and the first limit switch 21. For example, the stopper 15 provided at the leftmost end enables the piston rod 122 to obtain the maximum amount of protrusion.
Considering that the distance between the limiting block 15 and the first limiting switch 21 can be adjusted, the extending amount of the piston rod 122 can be adjusted, so that the adjustable limiting device is suitable for cylinders with different diameters and can be better and more conveniently applied to various cylinders.
Further, the limit plate 16 is disposed on the embrace circle holding arm 13 to move together with the embrace circle holding arm 13. The stopper plate 16 extends in the lateral direction.
And the second limit switch 22 for sensing the limit plate 16 is specifically arranged on the right end surface of the upright post 11 facing the embracing circular clamping arm 13. Likewise, the second limit switch 22 is an electro-optical proximity switch. The second limit switch 22 is used for inductive probe lateral positioning towards the limit plate 16.
In the process of withdrawing from the cylinder, the embracing circular clamping arm 13 moves leftwards along with the retraction of the piston rod 122, and the limiting plate 16 moves leftwards along with the retraction of the piston rod 122. While the second limit switch 22 is stationary. When the position-limiting plate 16 moves to the detection range of the second limit switch 22, the second limit switch 22 is triggered to output a detection signal to the controller. At this time, the controller receives the detection signal and controls the piston rod 122 of the cylinder 12 to stop the leftward retracting movement according to the detection signal to prevent the overstroke.
In summary, under the combined action of the first limit switch 21 and the second limit switch 22, the controller can control the extending amount and the retracting amount of the piston rod 122, that is, the piston rod 122 can only perform telescopic movement under the set parameters, so as to ensure that the piston rod 122 extends to moderately squeeze the cylinder 200 and is properly retracted to the non-squeezing operation state.
In this embodiment, the controller is also capable of controlling the speed of the telescopic movement of the piston rod 122 of the cylinder 12. Therefore, the embracing and clamping arm 13 has a fast mode and a slow mode relative to the extrusion cylinder 200, and an operator can select a proper speed to control the stretching and retracting of the oil cylinder 12 so as to adjust the roundness of the cylinder 200 better and more conveniently.
Referring to fig. 3 in combination with fig. 2, the circular holding arm 13 is provided with two clamping portions 131, and the two clamping portions 131 are respectively disposed at two ends of the opening and are disposed opposite to each other. In this way, the four clamping portions 131 on the two embracing circular clamping arms 13 are all located on the circumference of the same right circle to clamp and embrace the cylinder body 200 together.
Specifically, the embrace circular clamping arm 13 is an integrally formed structure, and two opposite sides of an end of the opening of the embrace circular clamping arm 13 respectively extend along the circumferential direction to form a flange 132. The two flanges 132 are provided with through holes facing each other.
The clamping portion 131 is a clamping roller. The clamping roller is clamped between the two flanges 132, and two ends of the clamping roller are rotatably inserted into the through holes through the rotating shafts 134. The periphery of the pinch roller exceeds the flange 132 so that the rolling surface of the pinch roller can contact the outer wall of the cartridge 200 to rollingly compress the cartridge 200 such that the deformed cartridge 200 returns to a circular shape.
Preferably, the clamping roller is made of relatively soft copper or nylon, so that the surface of the cylinder 200 is not damaged after the clamping roller contacts the cylinder 200.
Referring to fig. 4, each of the circular holding arms 13 is provided with three clamping portions 131.
The three clamping parts 131 are sequentially arranged from top to bottom along the arc-shaped profile of the embracing circular clamping arm 13; two of the clamping portions 131 are disposed at two ends of the opening, and the remaining one of the clamping portions 131 is disposed in the middle of the embracing clamp arm 13.
The three clamping portions 131 of each embracing gripping arm 13 are located on the circumference of the same circle, while the six clamping portions 131 of two opposite embracing gripping arms 13 are located on the circumference of an ellipse. Therefore, the clamping portions 131 can cooperatively and fittingly clamp an oval cylinder 200.
Of course, the number of the clamping portions 131 can be four or more, and the relative positions of the clamping portions 131 can be specifically adjusted to clamp the square or other specific-shaped cylinder 200.
In the present embodiment, the guide bar 14 has two. The two guide rods 14 are vertically spaced apart from each other in the height direction of the column 11, and the two guide rods 14 are symmetrically arranged about a transverse axis in the axial direction of the piston rod 122. In other embodiments, the number of the guide rods 14 may be multiple, and the multiple guide rods 14 are arranged at intervals along the height direction of the upright 11 to increase the stability and accuracy of the lateral movement of the embracing circular clamping arm 13.
In the present embodiment, the column 11 includes an inclined section 111 and a vertical section 112 which are integrally formed.
The vertical section 112 is located above and extends along a vertical axis. The oil cylinder 12, the embracing circular clamping arm 13 and the guide rod 14 are all arranged on the vertical section 112. And the lower end of the inclined section 111 is fixedly arranged, and the upper end of the inclined section 111 is connected with the vertical section 112. The inclined section 111 and the vertical section 112 form an included angle therebetween.
As shown in fig. 2, the inclined section 111 is inclined upward from the cylinder 200 to ensure that the center of gravity of the cylinder 12, the embracing clamp arm 13, the guide rod 14, and other components is projected on the center of the inclined section 111, thereby improving the stability of the whole upright 11.
With continued reference to fig. 5, the rounding device 10 further includes a linear guide 30 fixedly laid along the longitudinal direction of the cylinder 200 and a translation component movable along the linear guide 30.
The translation assembly comprises a mobile seat 41 and a linear actuation cylinder 42.
The movable base 41 is slidably provided on the linear guide 30. The upper end of the movable base 41 away from the linear guide 30 is connected to and supports the column 11, and the piston rod 122 of the linear driving cylinder 42 is connected to the movable base 41 to drive the movable base 41 to translate together along the linear guide 30. Therefore, the components such as the oil cylinder 12 and the rounding clamping arm 13 can move along the longitudinal direction of the cylinder body 200 along with the moving seat 41, and the rounding operation on all parts of the outer wall of the cylinder body 200 is conveniently realized.
In the present embodiment, the linear guide 30 has the advantages of high precision and good stability. Moreover, the power member for driving the movable base 41 to move employs a linear driving cylinder 42. The oil cylinder 12 of the linear driving oil cylinder 42 has a compact structure and is convenient to maintain.
Preferably, the linear guide rail 30 and the linear driving oil cylinder 42 are provided with a protection device, so that the influence of impurities such as dust and welding slag on the accuracy and the service life of the oil cylinder 12 and the guide rail can be effectively prevented.
In summary, the circle embracing mechanism 100 provided by the present embodiment has at least the following advantages and positive effects:
this embrace circle mechanism 100 has realized the automated control to the flexible volume of hydro-cylinder 12 through setting up first limit switch 21, second limit switch 22 and controller to replaced operating personnel's manual control operation, prevented that the piston rod 122 of hydro-cylinder 12 from excessively extrudeing barrel 200 and causing barrel 200 to warp.
During the process of pressing the cylinder, the guide rod 14 moves to the right along with the extension of the piston rod 122, and the stopper 15 moves to the right along with the extension. While the first limit switch 21 is stationary. When the limiting block 15 moves to the detection range of the first limiting switch 21, the first limiting switch 21 is triggered, and a detection signal is output to the controller. At this time, as the embracing circular clamping arm 13 synchronously moving with the piston rod 122 contacts and presses the outer wall of the cylinder 200, once the controller receives the detection signal, the controller controls the piston rod 122 of the oil cylinder 12 to stop the rightward extending movement according to the detection signal so as to prevent the excessively extending piston rod 122 from excessively pressing the outer wall of the cylinder 200. It is appropriate that the controller be able to control the amount of extension of the piston rod 122 by the action of the first limit switch 21, which ensures that the piston rod 122 is able to contact the cylinder 200 and moderately squeeze the cylinder 200. Damage to the cylinder 12 due to force interaction is likewise prevented.
In the process of withdrawing from the cylinder, the embracing circular clamping arm 13 moves leftwards along with the retraction of the piston rod 122, and the limiting plate 16 moves leftwards along with the retraction of the piston rod 122. While the second limit switch 22 is stationary. When the position-limiting plate 16 moves to the detection range of the second limit switch 22, the second limit switch 22 is triggered to output a detection signal to the controller. At this time, the controller receives the detection signal and controls the piston rod 122 of the cylinder 12 to stop the leftward retracting movement according to the detection signal to prevent the overstroke.
