Definitions

  • the invention relates to a tool for control of either nut and/or screw threads and the engagement length of the thread, which tool comprises a cabinet with a drive motor with an output shaft, which is connected to a plug gauge for its rotation, simultaneously with the direction of rotation and the axial movement being scanned and shown on a display.
  • Tools for control of threads are known both as manually operated tools, which can be thread fastened for control of flawlessness of the thread and where a housing extending around the gauge by the screwing in is displaced backwards in axial direction for determining the engagement length of the thread.
  • motor driven plug gauges which perform the same controlling without manual handling, are known.
  • DK 177439 B1 An example of such a motor driven tool is known from DK 177439 B1.
  • the motor 4 with a gearbox is loosely placed in a cabinet 1 supported by a sleeve 14, which moves between the motor and the inside of the cabinet and where around the motor shaft extends a coupling 25 to which the plug gauge 27 is fastened.
  • a tap 11 is screwed into the shaft end of the motor which tap can slide in an axially extending slot 12 in a measuring tube 8 and through a hole 13 in the housing 1. This ensures that the measuring tube 8 can be moved in axial direction but not turned.
  • this tool suffers the disadvantage of the motor and gear box being loosely embedded in the housing which causes an inaccurate alignment and thereby turning, due to possible deviation concerning the common axis of rotation in which the rotating parts move.
  • the opening 13 through the housing and the slot 12 through the measuring tube allows a possible entry for foreign bodies such as shavings, oil, dirt, which may affect the working and movement of the parts.
  • the slider rail serves partly as protection of the drive unit and partly as a measuring object as well as the engagement length of the thread can be registered in relation to the axial movement of the sliding rail.
  • providing the sliding rail with a spring it will be pressed against the measured object and thereby be a fixed point for the it position of the plug gauge.
  • providing the sliding rail with an end piece this will partly protect the plug gauge and partly ensure a reliable abutment against the object of measuring.
  • providing the sliding rail with a knob that moves in an axial running slot in the cabinet it will be possible to manually displace the sliding rail and thereby bring it backwards against the spring force for release of the plug gauge, when this is to be positioned in relation to the thread needing measuring.
  • the sliding rail will, by means of the spring force, stay in contact with the measuring object during the screwing in of the plug gauge.
  • fig. 1 shows the tool viewed in perspective with the sliding rail protruding
  • fig. 2 shows the tool with the sliding rail drawn back
  • fig. 3 shows the sliding rail itself in perspective
  • fig. 4 shows a section of the tool shown in fig.1.
  • the tool comprises a cabinet or housing 2 which is shaped as a customary handheld tool and conformed in size and weight for best possible handling with least possible strain of the body.
  • a cabinet or housing 2 which is shaped as a customary handheld tool and conformed in size and weight for best possible handling with least possible strain of the body.
  • the shape is determined by the practical use of the tool and by those parts featured in the tool.
  • these parts consist of a drive part comprising a motor 16 with a motor shaft 14.
  • This motor is embedded in a housing 13, which unit constitutes the driving part of the tool.
  • the motor 16 is in a commonly known way driven by a not shown battery.
  • a locking ring 10 is fastened, which abuts closely against the inner side of the cabinet and which is locked to it by means of a screw 11.
  • the sliding rail 7 itself is shown in fig.3. It is a completely closed piece which may have circular or other cross section profiles. There are no slots or openings in the sliding rail and thereby no possible entry for contamination to its inside by this path which would normally pose a big risk at places of control in production halls etc.
  • a pressure spring 12 is provided on the exterior of the housing 13 .
  • the purpose of this spring 12 is to move the sliding rail 7 by means of spring pressure, and moves on the outside of the motor housing 13 and protrudes.
  • the spring 12 abuts against the locking ring 10 while the opposite end abuts against the end flange on the sliding rail 7 so that the sliding rail 7, as shown in figs. 1 and 2, is moveable forwards in relation to the cabinet 1 and backwards as shown in fig. 2 respectively, against spring pressure.
  • the sliding rail 7 will serve as a protection tube for the plug gauge 17 for control of, in this instance, a nut thread.
  • Another plug gauge can be fastened to the tool when controlling a screw thread.
  • the plug gauge is rotated by the motor 16 and its output shaft 14, which is achieved by means of a carrier 15, as shown in fig. 4, which extends between the shaft and the shank of the plug gauge 17.
  • the carrier 15 is arranged as a sliding connection, which allows both rotation and axial movement of the plug gauge 17.
  • the sliding rail 7 has a length which together with a mounted end piece moves in the full length of the plug gauge as shown in fig. 4.
  • a scanning of the position of the sliding rail 7 will form a starting reference for the scanning, which can be viewed on a display 6 at the top of the cabinet 2. Furthermore, it will form an end measuring reference, when the plug gauge 17 is completely screwed in.
  • the knob moves in an axial slot 5 on the side of the cabinet and in this way, one can on the outside of the cabinet displace the sliding rail 7 in an axial direction.
  • the purpose of this is to expose the plug gauge 17, as shown in fig. 2, in connection with the use of the tool at the start of a control measuring.
  • the gauge 17 is exposed by drawing the knob 4 back in such a way that the plug gauge can easily be moved forward to abut against the screw thread in need of control
  • the knob 4 can released, after which the sliding rail will be moved against the object 7 by means of the spring pressure after which the start reference can be scanned.
  • the plug gauge 17 When the plug gauge 17 is screwed all the way in, its axial movement in relation to the at that moment stationary sliding rail 7 with the end piece abutting against the object can be scanned and the travel of the plug gauge 17 will thus be an expression of the engagement length of the thread. If the plug gauge 17 is not able to obtain the necessary engagement length of the thread, the thread will not be accepted.
  • the electric monitoring, of the motor 16 takes place by means of prior art scanning and monitoring systems, which are operated by knobs placed on the outside of the cabinet.
  • the system comprises controlling of the torque in such a way that it can be set for the desired torque.
  • the motor unit 13, 16 with the shaft tap 14 and the carrier 15 is completely contained in the sliding rail 7 and thereby protected against impurities and damages. Furthermore, the locked mounting of these parts to the cabinet ensures a completely precise axis of rotation, and thereby a completely stable and precise movement of the plug gauge.
