In general, when L2 needs to be trisected, four support bars are needed to represent the L2, but only one support bar needs to be reserved due to the difference of the distance between the first support bar and the fourth support bar by L2, that is, only 3 support bars are needed for trisection. Therefore, the controller can control the second stepping electric telescopic rod 4, the first motor 2, the second motor 6 and the first electric telescopic rod 3 to act according to the following steps so as to complete deformation simulation positioning:
s101, setting the vertical direction as the positive direction of a Z axis, determining the distance between the positioning coordinates (X0, Y0) and the origin of the coordinate system according to the input positioning coordinates (X0, Y0), subtracting X1 from the determined distance to serve as the length to be extended of the second step electric telescopic rod, judging whether the length to be extended is equal to the integral multiple of L2, if so, executing S107, otherwise, executing S102; in an initial state, the horizontal distance from the upper insertion rod of the second-step electric telescopic rod to the Z axis can be equal to the corresponding integral multiple of the stepping unit length of the second-step electric telescopic rod.
Step S102, dividing the length to be stretched by L2 to obtain a first integer and a first remainder, dividing the first remainder by delta X to obtain a second integer and a second remainder, judging whether the second remainder is less than delta X/2, if so, adding 1 to the second integer as P, and executing step S103, otherwise, adding 2 to the second integer as P, wherein P is an integer which is more than 1 and less than or equal to N, and executing step S103; at this time, the insertion rod on the second stepping electric telescopic rod is determined to be inserted into the insertion pin on the pth fourth telescopic rod from top to bottom.
And step S103, controlling the second stepping electric telescopic rod to extend by L = X3-X1 so that the inserted link is positioned right above the inserted pin of the P fourth telescopic rod from top to bottom in the target group, and then controlling the first electric telescopic rod to extend and retract so that the inserted link is inserted into the inserted pin of the P fourth telescopic rod in the target group, wherein X3 represents the X value corresponding to the inserted pin of the P fourth telescopic rod. When each group of fourth telescopic rods are locally stored and are arranged towards the left, the controller stores X-axis values X3 corresponding to the inserted pins on the fourth telescopic rods.
And S104, controlling the second motor to rotate by 90 degrees, keeping the telescopic end of the inner rod of the P-th fourth telescopic rod horizontal leftwards under the matching action of the inserted rod and the inserted pin, and rotating other fourth telescopic rods except the P-th fourth telescopic rod along with the third telescopic rod until the telescopic end of the inner rod is horizontal rightwards. In order to ensure that the corresponding fourth telescopic rod inserted into the insertion rod can not rotate along with the rotation of the second motor, and other fourth telescopic rods can rotate along with the rotation of the second motor, the existing structure can be adopted, for example, a round convex block can be arranged on the third telescopic rod, the third telescopic rod is cylindrical, the inner side of the sleeving interface of each fourth telescopic rod is provided with a matched recess, a corresponding annular stop block is arranged on the third telescopic rod for each fourth telescopic rod, the annular stop block is fixedly connected with the third telescopic rod and is in contact with the lower end of the corresponding fourth telescopic rod, therefore, the first electric telescopic rod can push the third telescopic rod to move downwards in the process of moving downwards. Because the other fourth telescopic rods are also provided with the supporting rods, in order to avoid the contact of the other supporting rods and the building board during deformation simulation, the second motor is controlled by the invention, and the other fourth telescopic rods rotate along with the third telescopic rod until the telescopic end of the inner rod is horizontally rightwards, so that the positioning and deformation accuracy can be ensured.
And S105, determining an X-axis value X4 corresponding to a support rod on the No. P fourth telescopic rod in the target group, subtracting the distance between the positioning coordinate (X0, Y0) and the origin of the coordinate system from the X4, dividing the subtraction result by L2 to obtain an integer to be signed as a third integer, and controlling the second stepping electric telescopic rod to stretch out and draw back the L2-the third integer. In this embodiment, when the controller locally stores that each group of fourth telescopic links is set to the left, the X-axis value X4 corresponding to the support rod on each fourth telescopic link. Due to the selection of the fourth telescopic rod, the length that the second stepping electric telescopic rod cannot be extended or contracted in steps, that is, the first remainder part, may be compensated, however, as described in step S102, the input positioning coordinate may still have a case where the distance between the input positioning coordinate and the origin of the coordinate system is not equal to the integral multiple of Δ X, that is, the distance between the input positioning coordinate and the origin of the coordinate system is subtracted by X4, and the result may not be equal to an integer, so that the integer obtained by dividing the result of the subtraction between the input positioning coordinate and the origin of the coordinate system by L2 in this step is used as a third integer, and then the extension or contraction of the second stepping electric telescopic rod is controlled by L2. When the sign of the third integer is positive, the X4 is greater than the distance between the positioning coordinate (X0, Y0) and the origin of the coordinate system, and the second stepping electric telescopic rod is controlled to contract by L2 × the third integer; and when the sign of the third integer is negative, the X4 is smaller than the distance between the positioning coordinates (X0, Y0) and the origin of the coordinate system, and the second stepping electric telescopic rod is controlled to extend by L2 × the third integer.
Step S106, controlling the first motor to rotate according to the connecting line of the positioning coordinate and the circle center and the included angle relative to the positive direction of the X axis, driving the second motor to rotate around the central vertical axis of the circular track through the second stepping electric telescopic rod and the P fourth telescopic rod on the premise that the P fourth telescopic rod and the second stepping electric telescopic rod are kept on the same straight line, and sliding along the circular track until the connecting line of the P fourth telescopic rod and the second stepping electric telescopic rod coincides with the connecting line of the positioning coordinate and the circle center. In order to ensure that the P-th fourth telescopic rod and the second stepping electric telescopic rod are kept on the same straight line when the first motor rotates, the horizontal sections of the pins and the inserting rods are square, and the size of each pin is matched with that of the inserting rod.
Step S107, controlling P =1, controlling the second stepping electric telescopic rod to extend by L = X2-X1, so that the insert rod on the second stepping electric telescopic rod is positioned right above the pin of the pth fourth telescopic pin in the target group, then controlling the first electric telescopic rod to extend and retract, so that the insert rod is inserted into the pin of the pth fourth telescopic rod in the target group, and returning to execute step S104.
In this embodiment, the controller locally stores: when the first electric telescopic rod drives the inserting rods on the second stepping electric telescopic rod to move downwards to be inserted into the inserting pins on the third telescopic rods, the minimum length of the first electric telescopic rod required to extend is obtained, and therefore when the controller in the steps S103 and S107 inserts the inserting rods 9 on the second stepping electric telescopic rod 4 into the inserting pins 10 corresponding to the fourth telescopic rods 8 in the target group, the length of the first electric telescopic rod which needs to extend can be obtained. Because of the existence of the third telescopic link, as shown in fig. 5, the inserted link 9 is inserted into the corresponding bolt 10, no matter whether the distance between two adjacent bolts is equal to the step-by-step unit length of the first electric telescopic link, the inserted link can be ensured to be accurately inserted into the corresponding bolt under the driving of the first electric telescopic link, and the distance between two adjacent bolts is not necessarily equal to the step-by-step unit length of the first electric telescopic link, so that the distance between the fourth telescopic links can be reduced, the device has a small size, that is, even if the first electric telescopic link is a step-by-step electric telescopic link, the inserted link can be ensured to be accurately inserted into the corresponding bolt.

step S203, extending the jth fourth telescopic rod rightwards according to the scale marks on the jth fourth telescopic rod until the scale of the intersecting of the inner rod and the outer rod of the jth fourth telescopic rod is the calculated distance of the jth fourth telescopic rod extending rightwards;
and S204, determining whether j is N, if so, ending the adjustment, otherwise, returning to the step S202, and continuously adjusting the next fourth telescopic rod until all the fourth telescopic rods are adjusted.
In the invention, in the process of adjusting the distance between the support rods, each third cross rod is inserted into the jack of the bolt in the corresponding fourth telescopic rod, and under the limiting action of the third cross rod, each fourth telescopic rod extends to the right for a corresponding distance, and meanwhile, the bolt on the corresponding fourth telescopic rod slides to the left for the same distance along the chute. After the user manually adjusts the fourth support rod, the adjusted N and Δ X are input to the controller, and the controller performs deformation simulation positioning according to the steps S101 to S107.
In the above embodiment, when the first electric telescopic rod 3 is a stepping electric telescopic rod, the vertical length of the inserting rod 9 and the vertical distance between the lower end of the supporting rod 11 on each fourth telescopic rod 8 and the inner side of the bottom end of the corresponding bolt can be equal to the stepping unit length of the first electric telescopic rod 3, so as to ensure that the positioning accuracy is improved and the deformation unit length in the vertical direction is not affected. However, when the first electric telescopic rod is a stepping electric telescopic rod, the stepping unit length of the first electric telescopic rod is fixed, and a user also expects to be able to reduce the deformation unit length and improve the accuracy of the deformation in the vertical direction. How to improve the positioning accuracy and the vertical deformation accuracy is a problem which needs to be solved urgently. Therefore, the arrangement of the third telescopic rod and the fourth telescopic rod on the third telescopic rod is further designed. With reference to fig. 10 and 11, the difference between the embodiment shown in fig. 10 and the embodiment shown in fig. 1 is that two groups of fourth telescopic rods are sequentially sleeved on the third telescopic rod from top to bottom, the structure of each group of fourth telescopic rods is the same, for the upper and lower groups of fourth telescopic rods, the difference between the Z-axis values corresponding to the two uppermost telescopic rods in the two groups is equal to Δ Z, and Δ Z is equal to one half of the step unit length L1 of the first electric telescopic rod. Under the initial state, the flexible end of interior pole of each fourth telescopic link in the first group of fourth telescopic link from top to bottom is towards left, the flexible end of interior pole of each fourth telescopic link in the second group of fourth telescopic link is towards forward or backward (forward in figure 10), the contained angle of upper and lower two sets of fourth telescopic links is 90 degrees, first electric telescopic handle 3 contracts completely and its flexible end of its interior pole equals the integral multiple of L1 with the vertical distance between the bottom inboard of the flexible bolt 10 of the uppermost fourth in this first group, the Z value that the lower extreme of inserted bar 9 corresponds on this second electric telescopic handle 4 is Z1. This controller can be according to this second step motion electric telescopic handle of following step control, first motor, second motor and first electric telescopic handle action this moment to accomplish deformation location and simulation:
and S310, selecting one group of the fourth telescopic rods as a target group according to Z0 in the input coordinates (X0, Y0 and Z0). Wherein, step S310 may include: judging whether the result of Z1-Z0 is equal to the integral multiple of L1, if so, taking the first group of fourth telescopic rods from top to bottom as a target group, otherwise, dividing the result of Z1-Z0 by L1 to obtain a fourth integer and a fourth remainder, judging whether the fourth remainder is less than delta Z/2, if so, enabling Q =1, otherwise, enabling Q =2, and after determining Q, taking the fourth telescopic rods of the Q group from top to bottom as the target group.
And S320, controlling the second motor to rotate to drive the inner rod telescopic end of each fourth telescopic rod in the target group to face to the left. The controller locally stores an included angle between two groups of fourth telescopic rods from top to bottom, and after a target group is determined, the controller controls the second motor to rotate the included angle according to the included angle between the target group and the first group of fourth telescopic rods (if the target group is the first group of fourth telescopic rods, the included angle is 0, and if the target group is the second group of fourth telescopic rods, the included angle is 90 degrees), so that the inner rod telescopic end of each fourth telescopic rod in the target group faces to the left.
Step S330, controlling the second-step electric telescopic rod 4 and the first electric telescopic rod 3 to move according to (X0, Y0) in the coordinates (X0, Y0, Z0) so as to insert the inserting rod 9 on the second-step electric telescopic rod 4 into the plug pin 10 corresponding to the fourth telescopic rod 8 in the target group, and then controlling the second-step electric telescopic rod 4 and the first motor 3 to move so as to enable the coordinates corresponding to the supporting rod 11 on the corresponding fourth telescopic rod 8 inserted with the inserting rod 9 to be (X0, Y0), thereby completing the deformation simulation positioning. Step S330 specifically includes performing deformation simulation positioning according to the above steps S101 to S107 based on (X0, Y0) in the coordinates (X0, Y0, Z0).
Step S340, after the deformation simulation positioning is finished, setting a Z-axis value corresponding to the bottom end of the supporting rod on the corresponding fourth telescopic rod inserted with the inserted rod to be Z3, dividing the Z3-Z0 result by L1 to obtain a fourth integer, and controlling the first electric telescopic rod to extend by L1 x the fourth integer.
In this step, the controller locally stores: when the first electric telescopic rod drives the inserted bar on the second stepping electric telescopic rod to move downwards to be plugged with the pins on the third telescopic rods respectively, the minimum length required to be extended by the first electric telescopic rod is stored, and after the minimum length corresponding to the extension of the first electric telescopic rod is stored, the Z-axis value corresponding to the bottom end of the supporting bar on the third telescopic rod when the inserted bar is plugged with the pins on the corresponding third telescopic rods, therefore, when the controller in the step S330 inserts the inserted bar 9 on the second stepping electric telescopic rod 4 into the pin 10 corresponding to the fourth telescopic rod 8 in the target group, the length that the first electric telescopic rod should be extended can be known, and in the step S340, the controller can learn the Z-axis value Z3 corresponding to the bottom end of the supporting bar on the corresponding fourth telescopic rod into which the inserted bar is inserted. Wherein, the building board can be arranged below the lower end of the support rod on the fourth telescopic rod at the lowest, if the corresponding Z value is Z ', when the input coordinate is (X0, Y0, Z0), the deformation quantity of the building board at the corresponding point is Z0-Z'.
According to the embodiment, when the first-step electric telescopic rod is used for deformation adjustment and the second-step electric telescopic rod is used for positioning, the step unit length of the first-step electric telescopic rod and the step unit length of the second-step electric telescopic rod can be reduced, and the positioning and deformation adjustment precision is improved. It should be noted that: the support rod on the fourth telescopic rod is located on the telescopic axis of the fourth telescopic rod.
