Abstract

A CARBON FOR WIRING SCALES, comprising a housing with symmetrical grooves along its inner conical surface and accommodated in it an axially spring-loaded floating sleeve with rollers cooperating with the grooves, and an emphasis for a pin, characterized in that, in order to improve reliability, the housing is provided with a leash , and on the outer surface of the sleeve is made a groove with a conical section that interacts with the leash. (L 1C | SP O)

Description

The invention relates to devices for assembling threaded connections, in particular, cartridge-type tools for screwing in studs. A known cartridge for tightening the studs comprises a housing in which sliding threaded cams and an emphasis are placed, the cartridge’s cams are made with edges beveled to the plane of their connector, and the stop is made with an additional spherical bearing surface interacting with the edges I. However, the cartridge when turning the pin In the assembled product, it captures the stud for the threaded part, which at large toughness of their moments leads to the displacement of the cams that capture the stud, and as a result, the thread jamming due to the gaps and def rmatsii cartridge parts. Closest to the invention is a cartridge for tightening the studs, comprising a housing with symmetrical grooves along its inner conical surface and an axially spring-loaded floating sleeve with rollers cooperating with the grooves and anvil stop. The studs are wrapped around the cylindrical part by means of rollers located in a spring-loaded floating sleeve 2. The cartridge has a drawback that is possible to wring out the thread, since in a free state the sleeve with rollers occupies an indefinite position, at which the rollers can be stuck or misaligned, and causes the threading of the studs when the cartridge is put on the stud. The aim of the invention is to increase reliability. This goal is achieved by the fact that, in the cartridge for tightening the studs, comprising a housing with symmetrical grooves along its inner conical surface and accommodated in it an axially spring-loaded floating sleeve with rollers cooperating with the grooves and an emphasis for, the housing is equipped with a leash, and the outer surface of the sleeve is made a groove with a conical section that interacts with the leash. FIG. 1 shows a cartridge for wrapping the studs, a slit; in fig. 2 is a view A of FIG. one; in fig. 3 - sleeve reamer. A cartridge for tightening the studs 1 with a gripping part of the cylindrical part of the stud 1 comprises a body 2 and a sleeve 3 disposed therein, spring-loaded relative to the inner end of the body 2 by means of a spring 4. An axial stop 5 is placed in the end face of the sleeve 3, made in the form of a screw with an adjusting nut 6, providing the required extension of the stop 5, defining the gripping point for the hairpin 1. On the outer surface of the sleeve 3, a groove 7 is made with a conical section 8. In this case, the groove 7 is formed by overlaying elements 9 and 10 welded to the sleeve 3, but may kzhe be manufactured by any other means, e.g., milling. In the hole 11 of the housing 2 is installed a leash-12, made in the form of a screw, interacting with its cylindrical part with the groove 7 of the sleeve 3, and when interacting with the conical section 8 of the groove 7, the leash 12 fixes the maximum solution of the rollers 13 placed in the sleeve 3 and interacting with the conical surface 15 of the housing 2. The cartridge works as follows. The cartridges are mounted onto the spindle of the wrenches mounted in a multi-spindle box (not shown). A lot of the spindle box works in the following cycle: fast advance, boxes, wrapping all the studs, stopping the rotation, fast withdrawal of the box. When the carton is quickly brought in, the cartridge is freely put on the pin 1, previously applied for 2-3 threads into the main (body) part (not shown). When the cartridge moves on the stud 1, the end of the stop 5 rests on the end of the stud 1, while the stop 5 together with the sleeve 3, in which the rollers 13 are located, stops. The housing 2 continues to move forward until the rollers 13 are in contact with the conical surface 15 of the housing 2 and the cylindrical surface of the stud 1. After touching these surfaces, a small movement of the housing 2 takes place in front of and thereby the wedging of the stud 1 between the rollers 13 under the force of the spring 4. Clamp and the rolling of the stud 1 is carried out by rotating the roller cartridge, which through the rollers 13 transfers the rotation of the stud 1, since the taper surface 14 of the housing 2 is made in the form of three cylindrical ditches about 15 with offset centers (Fig. 1). After screwing the stud 1 to the desired torque and stopping the rotation of the cartridge, the roller cartridge is withdrawn from the screwed stud 1. The cartridge is removed when the spindle box is quickly retracted to the initial position, with the stop 5, the sleeve 3, the rollers 13 remain in place for some time, and the body 2 of the cartridge is moved upwards, releasing the rollers 13 from the clamping. The body 2, continuing to move together with the driver 12, seizes the sleeve 3 last and holds it in the body 2 from falling out. In the free state of the cartridge, the sleeve would have the ability to rotate relative to the housing 2, which would result in the next insertion of the cartridge on the new stud, 1, in which the rollers 13 were stuck on the thread of the stud 1 and see the thread.
In order to avoid thread squeezing when putting the cartridge on the stud, it is necessary that the sleeve 3 be in a certain fixed position, ensuring that the rollers 13 are located at a distance as far as possible from the vrash axis, ie the cartridge, as shown in FIG. 2. To achieve this goal, a groove with a tapered element is made on the sleeve 3, which, when interacting with the driver 12 and the action of the spring 4, ensures that the rollers 13 are located at the maximum diameter.
The proposed cartridge prevents damage to the surface of the studs during assembly and disassembly operations.
