Description

Technical Field

[0001] This utility model relates to the field of PVC pipe technology, and in particular to a PVC pipe outer diameter calibration device. Background Technology

[0002] PVC pipes are widely used. For PVC pipe production lines that connect to automated packaging machines, it is necessary to inspect the outer diameter of the PVC pipes to prevent substandard products from entering the market.

[0003] The existing method of inspecting the outer diameter of PVC pipes mainly involves manual inspection using vernier calipers. This method is cumbersome, has a long measurement cycle, seriously affects production efficiency, cannot meet the requirements of the current fast production pace, and cannot measure specific values ​​one by one, so only random sampling is possible, which makes it easy for unqualified products to enter the market.

[0004] To address this issue, we propose a PVC pipe outer diameter calibration device. Utility Model Content

Fixed discs are installed on both sides inside the fixed support blocks. The fixed discs are sleeved on both ends of a ball screw. Sliding blocks are installed on the surface of the ball screw, and a fixed platform is fixedly installed on the upper end of the sliding blocks. A calibration device is installed on the upper end of the fixed platform through the fixed blocks.

[0007] Preferably, the fixed support block has grooves on both sides, and the size of the grooves is adapted to the size of the sliding block.

[0008] Preferably, the surface of the sliding block is provided with a screw hole adapted to the ball screw, and the surface diameter of the fixed disk is larger than the surface diameter of the sliding block.

[0009] Preferably, the upper surface of the fixed platform is provided with a groove, and a calibration device connected to a fixed block is fixedly installed inside the groove.

[0010] Preferably, the calibration device is divided into upper and lower parts, which are effectively connected by a hinge in the middle.

[0011] Preferably, the surface of the calibration device is fixedly equipped with an upper mounting groove and a lower mounting groove, and the surfaces of the upper mounting groove and the lower mounting groove are provided with holes, and mounting pins (24) are fixedly inserted into the holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This device is designed to allow the calibration device to be opened by pulling out the mounting pins from the inside of the upper and lower mounting slots. The calibration device is then opened and closed by the action of the hinge. The calibration device is fixedly installed on the top of the fixed block and effectively supported by the fixed platform. This facilitates the separate fixing of two sets of pipes, reduces cumbersome operation methods, shortens the measurement cycle, improves production efficiency, and meets the requirements of the current fast production pace.

[0013] 2. This device is equipped with a drive motor that rotates the ball screw inside the fixed support block. The two ends of the ball screw are sleeved inside the fixed disc, which drives two sets of sliding blocks installed on the surface of the ball screw to move in opposite directions, thereby moving the fixed table. This facilitates effective adjustment for pipes of different lengths and sizes, makes it easy to fix, prevents them from falling off or loosening, avoids affecting production efficiency, and improves work requirements.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-4A PVC pipe outer diameter calibration device includes: a base 1, with fixed support blocks 11 fixedly installed on both sides of the upper end of the base 1 to facilitate the effective fixed support of a sliding block 14 and to allow it to slide inside a groove to prevent jamming; fixed discs 12 are installed on both sides inside the fixed support blocks 11, and the fixed discs 12 are sleeved on both ends of a ball screw 13, so that the ball screw 13 is connected through the bearings inside the fixed discs 12 to drive the ball screw 13 to rotate effectively and prevent jamming during rotation; a sliding block 14 is installed on the surface of the ball screw 13, and a fixed platform 15 is fixedly installed on the upper end of the sliding block 14; a calibration device 2 is installed on the upper end of the fixed platform 15 through a fixed block 25, so that the calibration device 2 can be effectively fixed and installed on the pipe, allowing two sets of pipes to be aligned and calibrated to prevent misalignment.

[0018] Furthermore, refer to Figure 1 and Figure 2 It can be seen that the fixed support block 11 has grooves on both sides, and the size of the grooves is adapted to the size of the sliding block 14. This facilitates the effective fixed support of the sliding block 14 when the two sets of sliding blocks 14 move, and allows the sliding block 14 to slide inside the grooves to prevent jamming.

[0019] Furthermore, refer to Figure 2 and Figure 3 It can be seen that the surface of the sliding block 14 is provided with a screw hole that matches the ball screw 13, so that the sliding block 14 can move on the surface of the ball screw 13 and prevent jamming during movement. The surface diameter of the fixed disc 12 is larger than the surface diameter of the sliding block 14 to prevent the sliding block 14 from detaching from the surface of the ball screw 13 during movement and to prevent it from falling off. The upper surface of the fixed platform 15 is provided with a groove, and the calibration device 2 connected to the fixed block 25 is fixedly installed inside the groove, so that the calibration device 2 can be effectively fixed and supported by the fixed block 25 to prevent shaking.

[0020] Furthermore, refer to Figure 4 It can be seen that the calibration device 2 is divided into upper and lower parts, and is effectively connected in the middle by a hinge 21, which facilitates the effective fixing and installation of the calibration device 2 on the pipe, so that the two sets of pipes can be aligned and calibrated to prevent misalignment.

[0021] Furthermore, refer to Figure 4 It can be seen that the surface of the calibration device 2 is fixedly equipped with an upper mounting groove 22 and a lower mounting groove 23. Holes are opened on the surface of the upper mounting groove 22 and the lower mounting groove 23, and mounting nails 24 are fixedly inserted into the inside of the holes to facilitate effective fixation and prevent the pipe from loosening during the fixed docking, thereby improving the efficiency of docking calibration.

[0022] Working principle: In use, by pulling out the mounting pins 24 installed inside the upper mounting slot 22 and the lower mounting slot 23, the upper and lower parts of the calibration device 2 are connected by the hinge 21, allowing the calibration device 2 to open and close. Two sets of tubing are placed inside the calibration device 2, allowing the calibration device 2 to effectively cover the tubing. The mounting pins 24 are inserted into the upper mounting slot 22 and the lower mounting slot 23, and the calibration device 2 is fixedly installed at the lower end of the fixing block 25 and at the upper end of the fixing platform 15. At this time, the drive motor 16 is started, causing the ball screw 13 inside the fixing support block 11 to rotate effectively. The two ends of the ball screw 13 are sleeved inside the fixing disc 12, and the fixing support block 11 is installed at the upper end of the base 1. At the same time, when the ball screw 13 rotates, it drives the sliding block 14 installed on the surface of the ball screw 13 to move, and the fixing platform 15 installed on the upper end of the sliding block 14 moves accordingly.
