Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not to be construed as limiting the invention.
The cable torsion fatigue eliminating mechanism of the actuating mechanism shown in fig. 2-8 comprises an actuating mechanism 1, a base 2, a connecting shaft 3, a drag chain component 4 and a driving component 5.
Wherein the connecting shaft 3 is rotatably supported by the base 2 and the rotation of the connecting shaft 3 is controlled by the driving part 5;
the drag chain component 4 comprises a disc framework 41 and a drag chain 42, wherein one end of the drag chain 42 is wound and attached on the circumference of the disc framework 41; the other end of the drag chain 42 is fixed to the base 2 and is in a relaxed state, i.e., the shape of the end is not a straight line of tension, but a curved relaxed state; the drag chain 42 serves to protect the cable within it, with the cable and drag chain 42 running in unison. The structure of the drag chain 42 is known in the art as a drag chain cable and will not be described in detail herein.
One end of the connecting shaft 3 is fixedly connected with the executing mechanism 1, and the other end of the connecting shaft 3 is coaxially and fixedly connected with the disc framework 41, so that the connecting shaft 3, the disc framework 41 and the executing mechanism 1 synchronously move;
the cable fixedly connected with the actuating mechanism 1 sequentially passes through the axial direction of the connecting shaft 3, the axial direction of the disc skeleton 41 and the inside of the drag chain 42 and then enters the external power supply equipment; in order to enable the cable to be connected in the axial direction of the connecting shaft 3, as shown in fig. 14, it is preferable to form a wiring groove on the outer surface of the connecting shaft 3; or a through hole for wiring is formed in the connecting shaft 3; or the connecting shaft 3 is made into a split structure with the inner part and the outer part sleeved, the outer surface of the mandrel in the inner part is axially provided with a wiring groove, the outer part of the mandrel is fixedly sleeved with a sleeve, and the sleeve plays a role in protecting the wiring groove. The outer surface of the connecting shaft 3 is preferably grooved to maintain the strength of the connecting shaft.
The driving part 5 drives the connecting shaft 3 to rotate so as to drive the actuating mechanism 1 and one end of the drag chain 42 to rotate around the connecting shaft 3, so that the cable is wound or unwound on the disc skeleton 41, and the length wound on the disc skeleton 41 in the circumferential direction is changed.
In this way, the actuator 1 does not twist the cable when performing the rotation action, but follows the rotation of the drag chain.
In a preferred embodiment of the present invention, as shown in fig. 13, the disc skeleton 41 includes a plurality of fixing posts 413 arranged along the circumferential direction of the disc skeleton 41, a first disc 411 and a second disc 412 arranged opposite to each other;
the first disc 411 is coaxially and fixedly connected with the other end of the connecting shaft 3;
the fixing column 413 is vertically and fixedly connected with the first disc 411 and the second disc 412, and one side of the drag chain 42 is abutted by the fixing column 413, namely, the radial inner side of the disc skeleton 41, so that the inner side of the drag chain 42 is attached to the fixing column 413.
The drag chain member 4 further includes a plurality of rotating rollers 44 surrounding the outside of the disc skeleton 41 in a circle and a drag chain holder plate 43 fixed to the base 2, the rotating rollers 44 being rotatably provided on the drag chain holder plate 43 to rotatably support the other side of the drag chain 42, i.e., the radially outer side of the disc skeleton 41. The rotating rollers 44 are preferably bearings, and the rotating rollers 44 help the drag chain 42 move more smoothly and smoothly. The drag chain is prevented from rotating too fast during opening, and is deployed too far in the radial direction under inertia, and is blocked by the rotating rollers 44. The hollow of the drag chain bracket plate 43 is provided with a hole for the connecting shaft 3 to be connected to the first disc 411 in an extending manner. The end surface of the connection shaft 3 is connected with the first disc 411 by a screw, and the drag chain bracket plate 43 rotatably supports the connection shaft 3 by a connection member such as a bearing.
In a preferred embodiment of the present invention, when the actuator 1 is not rotated, one end of the drag chain 42 is in a circular arc shape with an angle greater than 180 ° and attached to the circumference of the disc frame 41, and the drag chain 42 extends downward from the disc frame 41 to form a straight line segment to leave the disc frame 41, and the straight line segment is fixed to the base 2 after being rotated downward of the disc frame 41.
Specifically, as shown in fig. 8, after the cable passes out from the other end of the connection shaft 3, it passes through the first disc 411 and then extends vertically downward to the drag chain 42, that is, the six o' clock direction in which the cable starts the first disc 411. A cylinder is vertically fixed to the outer circumferential side of the first disc 411, and a hole is formed in the cylinder for passing a cable passing through the connection shaft 3 to enter the drag chain 42. The drag chain 42 winds the disc skeleton 41 upwards and anticlockwise by more than 180 degrees, reaches a straight line segment, passes through the straight line segment, is in a bent shape continuously surrounding the disc skeleton 41, is positioned below the disc skeleton 41, and finally the drag chain 42 is fixed on the base 2 by a drag chain joint. The cable passes through the connecting shaft 3 and then enters the drag chain, is installed along the large semicircle, the vertical section and the rotary part of the drag chain, and the other part is connected with the next movement mechanism.
The winding angle of one end of the drag chain 42 in the circumferential direction of the disc skeleton 41 is preferably larger than the rotation angle of the actuator 1 and smaller than 360 °. The winding angle is larger than the rotation angle of the actuating mechanism 1, so that smooth rotation of the drag chain can be ensured, the actuating mechanism is turned over by 180 degrees, for example, the winding is over than half circle, the drag chain is not completely opened when the actuating mechanism is turned over by 180 degrees, the drag chain can have allowance, and the drag chain is not turned over by 180 degrees enough when the drag chain is less than half circle; a winding angle of less than 360 ° reduces the cable length.
When the actuator 1 performs the turning motion about the connecting shaft 3 for the first time, the length of the cable and the drag chain 42 wound around the disc skeleton 41 in the circumferential direction is reduced. I.e. the turning over process of the actuator 1 is the process of the drag chain 42 opening.
The actuating mechanism 1 is fixed at a cable interface, a disc framework 41 is designed by taking the turning axial direction of the actuating mechanism 1 as a circle center, the disc framework 41 synchronously rotates along with the actuating mechanism 1, one end of a drag chain is fixed at a tangent line position below the disc framework 41, the rest part of the drag chain is wound around a large semicircle along the disc framework 41 to reach a vertical direction, and the drag chain is fixed by a drag chain connector after being vertically distributed for a proper length and then wound around more than the semicircle on the side of the disc framework. The cable is installed through the drag chain, and the drag chain is partially connected into the electric cabinet or connected into the next group of drag chains.
7-12, in the process that the disc skeleton 41 rotates along with the actuating mechanism, the cable at the actuating mechanism until the cable wound on the disc skeleton 41 integrally rotates, the interior of the part of the cable is relatively static, no relative movement between the cable and the actuating mechanism exists, and no cable damage exists; a portion of the cable follows the circular arc path of the disc skeleton 41, which carries the adjacent drag chain links through the forward rotational opening and reverse rotational winding process. As the drag chain moves counterclockwise, the drag chain wound around the disc skeleton 41 is gradually opened to become a straight segment, and the straight segment drag chain is gradually lengthened. The slewing process is reversed.
In the rotating process of the actuating mechanism 1, the cable is in a reciprocating process of being unfolded into a straight line along with the circle of the drag chain form and being wound into a circle in a straight line, so that the torsion of the cable is converted into winding and opening, the cable is prevented from being directly twisted, and the cable is prevented from being different from the conventional drag chain moving mode, so that the purposes of reducing cable damage and prolonging service life are achieved. The cable torsion is converted into circumferential unwinding and winding, and the torsion damage is eliminated.
The cable torsion fatigue eliminating mechanism is particularly aimed at cables of key electric execution components with high cost and long period, effectively eliminates fatigue damage caused by torsion, reduces maintenance frequency, lowers maintenance cost, improves the utilization rate of equipment, solves the common problem of overturning application working conditions, and provides a new thought for industrial design.
In a preferred embodiment of the invention, as shown in fig. 5-6, the driving member 5 is a rotary cylinder or rotary electric cylinder with a hollow rotary shaft, which is an actuator for reciprocating a certain angular range of the output shaft by means of compressed air or a motor. The two cylinders have different power sources, and the electric cylinders are driven by a motor and a speed reducer, and the rotary cylinder is taken as an example for description. The connecting shaft 3 passes through the rotating shaft, and the connecting shaft 3 is fixedly connected with a flange of the rotating shaft. The rotary cylinders are generally classified into vane type rotary cylinders whose output shaft is cylindrical and rack and pinion type rotary cylinders whose output shaft is square and hollow, and this example uses a rotary electric cylinder with a hollow shaft, i.e., a hollow rotary shaft. The end of the rotating shaft is provided with a second flange 50, the connecting shaft is sleeved inside the rotating shaft, and the end of the connecting shaft is fixedly provided with another first flange as shown in fig. 14, and the two flanges are fixedly connected. The revolving cylinder is fixed on the base 2. The connecting shaft is driven by the rotary cylinder, so that the operation is simple and easy. The rotary cylinder has small volume and is arranged on the base 2. The structure is symmetrical and the stress is stable.
The rotary cylinder is fixed on the cylinder body mounting seat 51, and the rotary cylinder and the cylinder body mounting seat 51 are sequentially sleeved outside the connecting shaft 3.
As shown in fig. 2, the cylinder mount 51 and the rotary cylinder rotatably support both ends of the connecting shaft 3. One end of the connecting shaft 3 is fixed to the rotary cylinder through a flange, and the connecting shaft 3 is sleeved inside the cylinder mounting seat 51 and penetrates out. The cylinder body mounting seat 51 is internally provided with a hollow cylindrical member 52, and the cylindrical member 52 is fixedly sleeved outside the connecting shaft 3. The cable is sleeved and protected at the outgoing line position, so that the situation that the cable is out of the driving electric cylinder or the center shaft of the driving air cylinder is poor in position and posture, and friction between the cable and other parts is avoided. The cylinder mount 51 is also used to fixedly attach the tow chain component. The drag chain support plate 43 is fixed on the cylinder body mounting seat 51, the end of the connecting shaft 3 is fixedly connected with the first disc 411, and the axis of the first disc 411 is provided with a through hole for the cable to extend out from the inside of the connecting shaft 3
In a preferred embodiment of the invention, an auxiliary plate 6 is also included, which is fixed between the actuator 1 and the connecting shaft 3, the auxiliary plate 6 being intended to support the cable. Since the head of the cable at the actuator 1 is angled, no length arrangement is made along the axial direction of the connecting shaft 3. The cables here are usually left free. For this purpose, an auxiliary plate 6 is provided, the auxiliary plate 6 being used to receive the cable before the actuator 1 is turned over; in addition, the cable and the auxiliary plate 6 can be fixed through the buckle, so that the cable is ensured to be static relative to the actuating mechanism 1 in the overturning process.
The elimination mechanism can be widely applied to the application of 3D pin detection of an automobile control unit. Line laser scanners and their cables are relatively expensive electrical components, often used for non-contact measurements. While the application of this measurement connector pin 3D position detection requires 2-directional scan data. In order to save the cost, a laser head overturning mode is adopted, and an eliminating mechanism is combined.
