Description

Technical Field

[0001] This utility model belongs to the field of pipeline construction technology, and specifically relates to a pipe fitting connection locator. Background Technology

[0002] Modern construction companies have increasingly higher requirements for the installation of various pipe fittings. However, during the installation process, due to the uneven technical level of construction personnel and the lack of uniformity in standards, various construction quality problems such as uneven pipe installation, imprecise flange connection, and misaligned bolt holes are easily caused. These problems seriously affect the installation accuracy of the equipment, leading to subsequent rework such as water leakage, air leakage, and strong vibration. In severe cases, they can even cause major accidents.

[0003] To address the above problems, a pipe fitting locator is designed to replace manual alignment of pipe fittings. Utility Model Content

[0004] The purpose of this utility model is to provide a pipe fitting connection positioner.

[0005] This utility model is achieved through the following measures: a pipe fitting connection locator, characterized in that it includes two symmetrically arranged upright plates, a lead screw rotatably arranged between the two upright plates, guide plates symmetrically arranged on both sides of the lead screw on the two upright plates, a movable plate connected to the lead screw by a thread, a limit plate fixedly arranged at the upper end of the movable plate above the guide plate, the lower end face of the limit plate contacting the upper end face of the guide plate, a dual-axis motor fixedly arranged on the limit plate, gears arranged on both output shafts of the dual-axis motor, lifting plates slidably arranged at both ends of the limit plate, the upper ends of the two lifting plates connected by a fixed plate, a chuck arranged on the fixed plate, and racks meshing with the gears arranged on both lifting plates outside the limit plate; An extension plate is fixedly provided at the upper end of any of the upright plates. A fixed platform and a movable platform are provided on the outer side of the extension plate. A V-shaped groove is provided at the upper end of the fixed platform and the lower end of the movable platform. A stud is fixedly provided on the fixed platform and on both sides of the V-shaped groove. The movable platform is sleeved on the stud and fixed by a nut. The two side walls of the V-groove are of equal length, and the connection between the two side walls is in the same plane as the axis of the chuck. One end of the lead screw extends out of the vertical plate and is connected to a motor with a reducer. The motor is fixed to the vertical plate by a base plate.

[0006] A bearing seat is provided on the limiting plate and below the output shaft, and the output shaft is mounted on the limiting plate through the bearing seat.

[0007] The limiting plate is provided with several screws that can press against the guide plate via threaded connection.

[0008] Limiting posts are provided on the outer side of the limiting plate and on both sides of the lifting plate.

[0009] The limiting post is provided with a screw that can press against the lifting plate via a threaded connection.

[0010] The lower ends of the two uprights are connected by a base plate, and several support legs are fixedly installed below the base plate.

[0011] The upright plate and the fixed platform are connected by diagonal braces.

[0012] The chuck is generally a 3-jaw chuck, including a chassis, a large bevel gear rotatably mounted on the chassis, three small bevel gears meshing with the large bevel gear, and three jaws. One side of the large bevel gear is provided with a planar thread structure, and the three jaws are equally distributed and mounted on the planar thread structure. It also includes a wrench that drives the small bevel gears to rotate. The wrench drives the small bevel gears to rotate, and the large bevel gears rotate. The planar thread structure on the large bevel gears causes the three jaws to move towards or out of the center at the same time.

[0013] How to use: Place one of the pipe fittings to be connected on the V-groove of the fixed platform (usually the longer of the two), place the movable platform on the stud and tighten the nut to fix it, and fix the pipe fitting through the two V-grooves; place the outer end of the other pipe fitting on the chuck, turn the wrench, and fix the pipe fitting through the chuck jaws.

[0014] After the two pipe fittings are fixed, the motor is started, the lead screw rotates, and the pipe fittings on the moving plate and chuck move along the axis of the lead screw toward the other pipe fitting until they come into contact.

[0015] When the two pipe fittings have a height difference, the dual-axis motor is activated. The dual-axis motor drives the gear to rotate, and during the rotation of the gear, it drives the rack meshing with it to move up and down until the two pipe fittings are completely concentric. This achieves the alignment and positioning of the two pipe fittings. After positioning is completed, the fittings can be locked by tightening screw one and screw two.

[0016] The beneficial effect of the technical solution provided by this utility model embodiment is that it can replace manual alignment of pipe fittings. Attached Figure Description

[0031] When the two pipe fittings have a height difference, the dual-axis motor 2016 is started. The dual-axis motor 2016 drives the gear 7 to rotate. During the rotation of the gear 7, the rack 8 meshing with it moves up and down until the two pipe fittings are completely concentric. This achieves the alignment and positioning of the two pipe fittings. After positioning is completed, the fittings can be locked by tightening screws 15 and 16.
