[0031] See also Figure 1-5 The wire grabbing and equidistant separation device comprises a support platform 1, the upper end of the support platform 1 is fixedly connected with a moving seat 2, both sides of the bottom of the support platform 1 are fixedly connected with connecting plates 3, the lower end of the connecting plate 3 is fixedly connected with a bracket 4, a linear guide rail 41 is installed between the inner walls of the bracket 4, two groups of clamping components 5 for grabbing the wire are slidably installed at the lower end of the linear guide rail 41, and two groups of transmission components 6 for driving the clamping components 5 to be equidistantly separated are installed at the central end of the bottom side of the support platform 1.

[0032] During use, in order to avoid the existing personnel adjusting the wire width by two hand wheels, which may easily cause the wire to be twisted, not on the same reference plane, and the wire entering the wire groove, which may easily fall off, resulting in low efficiency and poor tire body forming, in this embodiment, in order to improve the efficiency of the existing tire forming, a servo motor is used to control the equidistant separation of the manipulator by one-touch, replacing the original manual adjustment of the hand wheel in the tire forming production process, thereby effectively solving the manual operation fatigue and the error rate of the forming process, which is simple and convenient;

[0033] When in use, the wire manipulator grabs the wires on the wire placement seat at equal distances, and uses a servo motor to control the left and right width distance of the manipulator. In conjunction with the carcass drum forming production process, the steel wire grabbed from the wire placement seat is quickly separated and placed in the wire groove on the carcass drum.

[0034] See also Figure 1-3 and Figure 5 The clamping assembly 5 includes two groups of symmetrically distributed movable plates 51 provided on the lower side of the linear guide rail 41, and the upper ends of the movable plates 51 are fixedly connected with sliding sleeves 52 on both sides, and the sliding sleeves 52 are slidably connected to the linear guide rail 41.

The lower end of the movable plate 51 is fixedly connected with a linear guide rail 54, and the lower end of the linear guide rail 54 is slidably connected with two symmetrically distributed sliding sleeves 55.

[0035] During use of the present solution, by slidingly connecting the movable plate 51 with the surface of the linear guide rail 41, when the transmission assembly 6 is subsequently driven, the two groups of grabbing members 56 installed below are connected to the transmission end of the transmission assembly 6 by the positioning sleeve 53, so as to achieve equidistant displacement in the horizontal axis direction. At the same time, with the sliding installation of the linear guide rail 2 54 and the sliding sleeve 2 55, and the linear bearing sleeve 57 on one side of the grabbing member 56 being sleeved on the limit end surface of the transmission assembly 6, the claw arms of the single group of grabbing members 56 can be separated equidistantly again, thereby achieving equidistant positions in the vertical axis direction, which is beneficial for personnel to grasp wires of different sizes.

[0036] See also Figure 1-2 and Figure 5 A scale 58 is fixedly connected to the side end of the movable plate 51 , and a reading bar 59 is fixedly connected to the top side end of the grabbing member 56 , and the reading bar 59 is located on the outside of the scale 58 .

[0037] During use of the present solution, by installing a scale 58 on the side of the movable plate 51 and by installing a reading bar 59 on the claw arm of a single grabbing member 56, when a single group of grabbing members 56 is displaced in the vertical axis direction, personnel can judge the distance of equidistant separation of the grabbing members 56 in the vertical axis direction according to the scale indication of the reading bar 59 on the scale 58.

[0038] See also Figure 1-4, wherein a group of the transmission components 6 of the driving clamping components 5 equidistantly separated includes a positioning sleeve 61 fixedly connected to both sides of the bottom of the connecting plate 3, a transmission shaft 62 is rotatably connected between the inner walls of the two positioning sleeves 61, one end of the transmission shaft 62 penetrates to the outer side of the positioning sleeve 61 on one side, and a positioning shaft 63 is also fixedly connected between the inner walls of the two positioning sleeves 61, and the positioning shaft 63 is located on the upper side of the transmission shaft 62, and a servo motor 64 is installed between the inner walls of the movable seat 2, and a transmission wheel 65 is fixedly connected to the output end of the servo motor 64 and the outer end of one side of the transmission shaft 62, and a transmission belt 66 is sleeved between the upper and lower transmission wheels 65, and the outer ends of the transmission shaft 62 and the positioning shaft 63 are sleeved with two symmetrically distributed movable sleeves 67, the movable sleeve 67 is threadedly connected to the transmission shaft 62, and the movable sleeve 67 is slidably connected to the positioning shaft 63, and the side end of the movable sleeve 67 is inserted with a limiting shaft 68, and the limiting shaft 68 penetrates to the inner walls of the linear bearing sleeve 57.

[0039] More specifically: the transmission assembly 6 of another group of driving clamping assemblies 5 equidistantly separated includes two positioning seats 11 fixedly connected to the bottom of the connecting plate 3, the two positioning seats 11 are diagonally arranged, and a cylinder 12 is installed at the side end of the positioning seat 11, and a telescopic connecting rod 13 is fixedly connected to the output end of the cylinder 12, and the telescopic connecting rod 13 passes through the inner wall of the positioning sleeve 53 and is fixedly connected thereto by a nut.

[0040] In the process of using this solution, the specific implementation steps of isotropically separating the two sets of driving clamping components 5 are as follows:

[0041] First, the positioning seat 11 is fixed under the connecting plate 3, and the telescopic connecting rod 13 is connected to the positioning sleeve 1 53. The driving mode of the two groups of positioning seats 11 is synchronized through the PLC program, so that the left and right groups of grabbing members 56 connected by the movable plate 51 can achieve equidistant displacement in the horizontal axis direction. In order to ensure the stability of the position in the horizontal axis direction, the limit shaft 68 penetrates into the linear bearing sleeve 57 placed at the side ends of the left and right groups of grabbing members 56 to ensure the synchronization and stability of the horizontal axis displacement.

[0042] After the distance between the claw arms of the left and right grabbing members 56 is adjusted, the personnel can also drive the servo motor 64 placed inside the moving seat 2, so that its output end drives the transmission wheel 65 to transmit, and under the linkage of the transmission belt 66, the transmission shaft 62 connected below is rotated;

[0043] In this embodiment, the transmission shaft 62 is a left-handed screw rod, and its main structure is that one end is a left-handed screw thread, and the other end is a right-handed screw thread, just like the structure when two nuts on a rod can realize the movement in opposite directions at the same time, wherein the left side of the transmission shaft 62 is a right-handed screw thread, and the right side is a left-handed screw thread. The left-handed and right-handed screws in this scheme respectively represent the rotation direction of the screw when the screw moves. The main function of the screw rod is to realize the conversion of rotational motion into linear motion, so that the movable sleeve 67 can realize equidistant separation displacement in the vertical axis direction by being limited by the positioning shaft 63 and the left-right rotation of the transmission shaft 62;

[0044] Subsequently, since the limiting shaft 68 penetrates into the interior of the linear bearing sleeve 57 on the outside of the claw arm of the horizontal single-group grabbing member 56, when the movable sleeve 67 is equidistantly displaced in the vertical direction, the two sliding sleeves 55 are relatively displaced in the vertical direction on the surface of the linear guide rail 2 54, and at the same time, the claw arm of the single-group grabbing member 56 on the bottom side of the sliding sleeve 2 55 is equidistantly displaced in the vertical direction, thereby realizing the adjustment of the grabbing range of the mechanical claw again.

[0045] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
