[0015] The utility model discloses a fiberglass pipe clamp table winding molding positioning device, such as Figure 1-3 As shown, a positioning platform 1 is included. The positioning platform 1 is arranged at the bottom of the mold on the winding machine and can provide necessary positioning when a clamping platform is installed on the outer periphery of the glass fiber reinforced plastic pipe on the mold.

[0016] The positioning platform 1 is provided with a horizontally arranged measuring column 2, and a scale line 6 is provided in the length direction of the measuring column 2. The measuring column 2 is also equipped with a scale positioning hoop 3, and a locking screw 4 is provided at the bottom of the scale positioning hoop 3. A slide groove 11 matching with the locking screw 4 is provided on the measuring column 2, and the scale positioning hoop 3 can be positioned on the measuring column 2 by rotating the locking screw 4. The position of the scale positioning hoop 3 can be adjusted according to the scale line 6 according to the position requirements of the outer peripheral clamp platform of the glass fiber reinforced plastic pipe. The slide groove 11 is provided to provide guidance for the movement of the scale positioning hoop 3 and prevent the scale positioning hoop 3 from rotating around the measuring column 2. After being adjusted and fixed once, it can be used multiple times, and regular re-inspection can avoid the situation of each measurement and the error caused by rotation and sliding, saving time and having high stability.

[0017] Two telescopic caliber adjustment rods 8 are hingedly mounted on the scale positioning hoop 3, and a first nut 13 is hingedly mounted on each caliber adjustment rod 8. The threads in the two first nuts 13 are rotated in opposite directions. A caliber adjustment screw 7 is installed between the two first nuts 13. The opening and closing angle between the two caliber adjustment rods 8 can be adjusted by rotating the caliber adjustment screw 7. A swing rod 14 that can be rotated and locked is installed on the upper end of the caliber adjustment rod 8. A first positioning block 10 is installed on the swing rod 14 through a positioning screw 12. The two first positioning blocks 10 can be set correspondingly by adjusting the caliber adjustment screw 7 and the swing rod 14.

[0018] In order to ensure accurate positioning and rapid winding of the clamping platform, the metal clamp can also be designed according to the product shape, and the metal clamp is sleeved on the outer periphery of the FRP pipe, and the position is adjusted and clamped and positioned through the first positioning block 10, so that the winding of the FRP pipe clamping platform is simpler, faster and more convenient. The metal clamp is equivalent to the forming mold of the clamping platform, and the first positioning block 10 with adjustable position can play a corresponding limiting role on the metal clamp.

[0019] When using the FRP pipe clamp table winding molding positioning device, install the positioning table 1 at a suitable position of the winding machine equipment, install the measuring column 2 into the positioning table 1, first determine the width of the clamp table, and then select the first positioning block 10 of suitable width for installation, and then adjust the position of the first positioning block 10 on the molding positioning device according to the shape and size requirements of the FRP pipe to be processed, adjust the length position of the scale positioning hoop 3 on the measuring column 2, and lock the position after the adjustment is completed, and then adjust the opening and closing angle of the caliber adjustment rod 8 and the swing position of the swing rod 14 according to the shape and caliber of the FRP pipe, so that the first positioning block 10 is in a limited clamping state position suitable for the outer diameter of the FRP pipe clamp table. When used for the first time, it is necessary to use a measuring instrument to calibrate to avoid errors so that the positioning device is accurate.

[0020] When measuring with a traditional tape measure, the limit device on the opposite sides of the glass fiber reinforced plastic pipe is prone to tilt to one side, which is prone to dimensional deviation. In order to minimize the above deviation, the first positioning block 10 of appropriate width can be selected according to the width of the product clamp table. The diameter adjustment rod 8 and the swing rod 14 are adjusted according to the diameter position of the clamp table, so that the two first positioning blocks 10 are placed on the two opposite sides of the clamp table. At the same time, due to the existence of the slide groove 11, it will not rotate or slide during use and is relatively stable. Due to the different starting and ending points, the size needs to be calibrated with a steel tape measure, and the size of the measuring column 2 is recorded and used as a standard in the future. It can be used directly after calibration to avoid repeated measurements.

[0021] Furthermore, in order to realize the positioning and insertion between the measuring column 2 and the positioning platform 1, as Figure 4 As shown, the positioning platform 1 is provided with a hole matched with the measuring column 2, a second positioning block 15 is installed on the measuring column 2, and a communicating positioning groove 16 is provided on the hole of the positioning platform 1, and the positioning groove 16 is matched with the second positioning block 15. The arrangement of the positioning groove 16 and the second positioning block 15 can make the initial position of the measuring column 2 the same each time it is installed, eliminating the need for manual assistance during steel tape measurement and avoiding the starting point error caused by human reading.

[0022] Furthermore, a telescopic column 5 is installed in the length direction of the measuring column 2, and a scale line 6 and a slide groove 11 are provided on the telescopic column 5, and the slide groove 11 on the telescopic column 5 is arranged correspondingly with the slide groove 11 on the measuring column 2. The main body length of the measuring column 2 can be 2 meters, and the telescopic column 5 can protect two telescopic lengths, one section is 1.6 meters, and the second section is 1.4 meters, and the total telescopic distance can reach 5 meters.

[0023] Furthermore, in order to realize the telescopic adjustment of the length of the caliber adjustment rod 8, the first positioning block 10 is driven to adapt to the clamping platform of different shapes and outer diameters, such as Figure 5 and Figure 6As shown, a telescopic rod 17 capable of telescopic movement is installed in the caliber adjustment rod 8, a locking screw 18 is installed on the telescopic rod 17, and an avoidance groove 19 matching with the locking screw 18 is provided on the caliber adjustment rod 8. An arc-shaped pressing plate 20 is also installed on the locking screw 18 outside the caliber adjustment rod 8. Turning the locking screw 18 allows the screw head to press the arc-shaped pressing plate 20 against the caliber adjustment rod 8 to achieve position locking between the telescopic rod 17 and the caliber adjustment rod 8. When the locking screw 18 is loosened, the telescopic rod 17 can be adjusted in length relative to the caliber adjustment rod 8. The swing rod 14 is installed at the end of the telescopic rod 17, and the swing rod 14 is driven to move by the telescopic rod 17 to achieve position adjustment of the first positioning block 10.

[0024] Furthermore, in order to realize the rotation adjustment and rotation locking of the swing lever 14 and the aperture adjustment lever 8, the swing lever 14 is installed at the end of the aperture adjustment lever 8 through the direction adjuster 9, as shown in FIG. Figure 7 As shown, the direction regulator 9 includes a first end toothed disc 21 and a second end toothed disc 22 that can rotate with each other, the first end toothed disc 21 is connected to the caliber adjustment rod 8, and the second end toothed disc 22 is connected to the swing rod 14. A through hole is opened on the axis of the first end toothed disc 21 and the second end toothed disc 22, and a connecting bolt 23 is arranged in the through hole. One end of the connecting bolt 23 passing through the end toothed disc is equipped with a second nut 24. Rotating the second nut 24 can make the first end toothed disc 21 and the second end toothed disc 22 engage and lock with each other, so that the first positioning block 10 on the swing rod 14 can be rotated and locked relative to the caliber adjustment rod 8, and loosening the second nut 24 can adjust the rotation angle of the first positioning block 10 relative to the caliber adjustment rod 8.

[0025] The swing arm 14 can be rotated 360 degrees in one rotation direction and can lock its own position by connecting the bolt 23 and the second nut 24. When adaptive adjustment is required according to the clamping table, the second nut 24 needs to be loosened to allow the swing arm 14 to rotate relative to the caliber adjustment rod 8, so that the position of the first positioning block 10 can be adjusted.

[0026] A telescopic rod 17 capable of telescopic movement is arranged in the above-mentioned caliber adjustment rod 8, and a swing rod 14 is installed at the end of the telescopic rod 17 through a direction regulator 9, and the first positioning block 10 is driven by the swing rod 14 to adjust the angle position. The above-mentioned structures can be adjusted and matched with each other to adapt to clamps of various shapes and different outer diameters. In actual use, the opening size of the two caliber adjustment rods 8 can be adjusted by turning the caliber adjustment screw 7 according to the shape and outer diameter of the clamp, and then the extension length of the telescopic rod 17 can be adjusted according to the position of the glass fiber reinforced plastic pipe and the clamp, and the direction regulator 9 can be turned to arrange the two first positioning blocks 10 correspondingly and realize self-locking, so as to avoid the corresponding surface of the clamp to deviate to one side to cause size deviation.

[0027] The first positioning block 10 is mounted on the caliber adjustment rod 8 by means of a positioning screw 12, which is not only easy to replace different types of first positioning blocks 10, but also prevents the first positioning block 10 from sliding during the positioning and clamping process. When the same glass fiber reinforced plastic pipe has multiple clamping platforms of different sizes, first positioning blocks 10 of different widths can be selected and respectively mounted on each scale positioning hoop 3. After the positions are fixed, multiple clamping platforms of different sizes can be positioned at the same time, which is simple and convenient to operate with high efficiency.
