Description

Technical Field

[0001] The invention relates to a wire passing pipe positioning device. Background Art

[0002] The non-metallic tube is formed by winding on a mold. There is a mounting hole on the mold. After the winding is completed, the mounting hole is wound and cannot be seen. The mold is fixed on the equipment through a mandrel rod for winding. At present, the known installation method is to draw an axis along the axial direction on the outer circle of the mandrel rod before winding. The extension line of the axis passes through the center of the mold mounting hole. When installing the wire tube, the axis is visually aligned with the center of the wire tube for installation. The positioning of the wire tube is controlled by humans, with poor stability and sometimes large errors. After the product is processed, it is found that the position of the wire tube has a large deviation from the center of the mold mounting hole, which affects the appearance. In severe cases, the product cannot be used, which increases costs and prolongs product output time. It is not suitable for mass production. Summary of the invention

[0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned wire tube installation method and provide a wire tube positioning device, which can not only align the center of the wire tube with the mold installation hole, but also improve the wire tube installation efficiency and reduce the unqualified rate of wire tube installation.

[0004] The technical solution of the present invention is: one end of the connecting rod is connected to the positioning arc plate corresponding to the core shaft rod through the bracket, and the positioning arc plate has an arc plate symmetry line corresponding to the positioning line on the core shaft rod. The other end of the connecting rod is provided with a groove for locating the position of the wire passing tube on the non-metallic tube, and the center of the groove is in the same plane as the center of the mold mounting hole.

[0005] There is one connecting rod.

[0006] The bracket comprises two supporting plates and a connecting pipe connected between the two supporting plates. The lower ends of the two supporting plates are arc ends corresponding to the core shaft rod, and the positioning arc plate is connected to the two arc ends.

[0007] The upper ends of the two supporting plates are each provided with one or more mounting grooves, and the connecting rods are fixed at the mounting grooves via nuts.

[0008] The groove is a U-shaped groove.

[0009] The lengths of the two ends of the connecting rod thread are similar. After the connecting rod is tightened with threads, it can prevent the U-groove end rod from being too heavy and sagging. The diameter of the wire tube (in mm) is Φ, and the width of the U-groove of the connecting rod (in mm) is Φ+0.5<Φ<Φ+0.7. The width of the U-groove is slightly larger than the diameter of the wire tube to ensure that the wire tube can be put in without being too large.

[0010] Compared with the prior art, the invention has the characteristics of simple structure, easy processing and low production cost. Brief Description of the Drawings

[0017] Figure 1 , 2 , in FIGS. 4, two mounting grooves are opened at the upper ends of the two support plates 2 and 3. The middle parts of the two support plates are connected by a connecting pipe 6. The lower parts of the two support plates are connected to the positioning arc plate 1. The left end of the connecting rod 5 is fixedly connected to the mounting groove by a nut. There is no nut at the right end of the connecting rod 5. A U-shaped groove 7 is provided at the right end of the connecting rod 5. When the center of the wire passing pipe positioning device coincides with the center of the core shaft rod 8, the center of the U-shaped groove 7 of the connecting rod 5 coincides with the center of the wire passing pipe. Place and wind the wire passing pipe according to the center of the U-shaped groove 7 of the connecting rod 5, ensuring that the center of the wire passing pipe after winding is on the same center line as the center of the mold mounting hole. There is a positioning nut 9 on the core shaft rod 8 for positioning the position of the mold on the winding equipment. L5 is the distance between the center of the mold and the lower end face of the connecting rod 5.

[0018] The inner diameter Φ1 of the inner hole of the positioning arc plate 1 is equal to the outer diameter Φ2 of the core shaft rod 8. An arc plate symmetry line 10 is drawn along the axial direction on the outer diameter Φ3 of the positioning arc plate 1. The distance 0 < L1 < 60 mm between the left end face of the positioning arc plate 1 and the positioning nut 9. The distance between the right end face of the positioning nut 9 and the left end face of the wire passing pipe 11 is L2, and L1 + L3 < L2 < 70 mm, where L3 is the distance between the left end face of the positioning arc plate 1 and the bottom of the U-shaped groove 7 of the connecting rod 5. The depth distance of the U-shaped groove 7 of the connecting rod 5 is 75 < L4 < 150 mm, ensuring that the wire passing pipe 11 can just be placed into the U-shaped groove 7 of the connecting rod 5.

[0019] Figure 3Among them, the distance L6 from the center of the mold to the lower end face of the connecting rod is less than L5 and less than 2 mm. L6 is the dimension from the center of the non-metal pipe to the outer circle of the non-metal pipe (i.e., the radius of the non-metal pipe). Place the wire passing pipe positioning device on the mandrel rod 8, and ensure that the symmetry line 10 of the positioning arc plate 1 of the wire passing pipe positioning device coincides with the positioning line 12 passing through the center of the mold installation hole on the mandrel rod 8. Place the wire passing pipe 11 in the U-shaped groove 7 of the connecting rod 5 and fix the wire passing pipe 11 with wire, then it can ensure that the wire passing pipe 11 is aligned with the center of the mold installation hole.

[0020] Figure 5 Among them, the thickness of the support plate 3 is 12 - 18 mm. The thicker the thickness, the better its guiding performance for the connecting rod 5.

[0021] Figure 6 Among them, the closer the length L8 of the left threaded end rod of the connecting rod 5 is to the length L7 of the right threaded end rod, the better. The left and right ends of the rod are balanced to prevent the right end of the rod from sagging due to gravity, playing a counterweight role.

[0022] The lengths L7 and L8 at both ends of the connecting rod 5 are approximately equal.
