Abstract
The utility model relates to a special-purpose positioning device of front fan of diesel locomotive, which relates to a positioning device between a front fan and a gear shifting box of a 8B type diesel locomotive and a Dongfeng series diesel locomotive. The special-purpose positioning device mainly solves the problems of a well-known positioning device that one segment of an expansion probe of adial indicator must be disassembled, two dial indicators for measuring radial jumping and end surface jumping can not be simultaneously mounted, the dial indicators need disassembling and assembling repeatedly, directions need adjusting, work load is big, and measurement precision is low. The special-purpose positioning device is characterized in that two dial indicators which are in 90 degrees are mounted on a device frame, and the mounting position is that when the device frame is mounted on a rope connector for starting the gear shifting box, the probe of a dial indicator is contacted withthe periphery of a technique flange which is fixed on a front fan connector, and the probe of the other dial indicator is contacted with the end surface of the technique flange. The special-purpose positioning device does not need disassembling and assembling the dial indicators repeatedly and does not need adjusting direction, has convenient operation, improves positioning precision and working efficiency, and lowers labor intensity of employees.
Description
Technical field
The utility model relates to a kind of diesel locomotive front ventilator registration device, relates to 8B type locomotive front ventilator specifically, and the registration device between the front ventilator of Dongfeng series internal combustion locomotive vehicle and the startup change speed gear box.
Background technology
Must keep certain relative distance between the front ventilator of diesel locomotive and the startup change speed gear box, therefore when being installed, front ventilator must use registration device, existing 8B type locomotive front ventilator dedicated positioning device in use, be used to measure the dial measuring gauge of locomotive front ventilator radial runout and the distance deficiency of process flange on the device owing to be installed in, must use the flexible probe that dial measuring gauge the has a ball one section ability of dismantling during use, the dial measuring gauge of measurement locomotive front ventilator face runout and the distance of process flange are not enough equally, also must use the flexible probe that dial measuring gauge the has a ball one section ability of dismantling during use, and frock two dial measuring gauges being used to measure radial runout and face runout can not be installed simultaneously in use, after measuring radial runout, again during the measuring junction surface jitter, also to readjust the direction of device and just can load onto dial measuring gauge, not so do not adorn, because ventilating set is in location process, to change after screw is fastening, need add and subtract pad adjustment repeatedly, need to radially beat and face runout carry out repeated measurement, so not only increase work capacity, also prolonged work-hours.
Summary of the invention
The purpose of this utility model is at above-mentioned deficiency, and a kind of two dial measuring gauges that on the device frame, install and measure radial runout and face runout simultaneously that provide, processing ease, the device of the diesel locomotive front ventilator installing and locating of installing and locating precision height and high efficiency.
Technical solution of the present utility model is a dedicated positioning device of diesel locomotive front ventilator, it is characterized in that: on the device frame, two dial measuring gauges that are 90 degree mutually are installed, the installation site of two dial measuring gauges is, when the device frame is installed on the startup change speed gear box rope connection, wherein the probe of a dial measuring gauge be fixed on process flange circumferential contact on the front ventilator adaptor union, the probe of another piece dial measuring gauge contacts with the process flange end face.
Device frame described in the technical solution of the present utility model is the upper and lower horizontal edge that is connected with at a vertical edge, be connected with erection seat on the termination of following horizontal edge, erection seat is provided with and the hole of installing that the frame vertical edge parallels and being complementary with the pin that starts on the change speed gear box rope connection.
A dial measuring gauge described in the technical solution of the present utility model is fixed on by screw on the last horizontal edge of device frame, and another piece dial measuring gauge is fixed under the device frame on the erection seat on the horizontal edge termination by screw.
The utility model is owing to can install two dial measuring gauges simultaneously, thereby can be simultaneously to the front ventilator of diesel locomotive with start position between the change speed gear box and carry out radially location with end face, direction without repeated disassembled and assembled dial measuring gauge and setting device, therefore, easy to operate, improve the precision of installing and locating, reduced personnel labor, improved work efficiency.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the following fixed block left view of registration device frame among Fig. 1.
The specific embodiment
As shown in Figure 1, 2, on device frame 2, be fixed with and be two dial measuring gauges 3,4 that 90 degree are installed mutually, device frame 2 is made up of with the upper and lower horizontal edge that is connected with vertical edge vertical edge, the upper and lower transverse direction edge that is connected on the vertical edge is opposite, be a crank shape, be connected with an erection seat 1 on the termination of following horizontal edge, erection seat 1 is provided with and the mounting hole that installs that frame 2 vertical edges parallel and be complementary with the pin 10 that starts on the change speed gear box rope connection 8; One hundred table 3 is vertically mounted on the last horizontal edge of device frame 2 by screw 5, another piece dial measuring gauge 4 is installed on 2 times horizontal edge terminations of device frame on the stationary device seat 1, the installation direction of dial measuring gauge 4 is, axially vertical with the mounting hole on the erection seat 1, be fixed on the side of erection seat 1 with screw 6, two dial measuring gauges 3,4 concrete installation site is, to be fixed on erection seat 1 on 2 times horizontal edge terminations of device frame when being installed on the pin 10 that starts change speed gear box rope connection 8 by the mounting hole on it, the flexible probe that is fixed on the dial measuring gauge on the horizontal edge 3 on the device frame 2 contacts with the circumference of process flange 7 on being fixed on front ventilator rope connection 9, and the flexible probe that is fixed on the dial measuring gauge 4 on the erection seat 1 contacts with the end face of process flange 7; Its principle of work is: device frame 2 is by the mounting hole on the erection seat 1, be installed on the pin 10 that starts on the change speed gear box rope connection 8, to be connected the holding screw 11 on the erection seat 1 again, 12,13 tighten, device frame 2 promptly is fixed on and starts on the change speed gear box rope connection 8, adjust front ventilator, the flexible probe that is fixed on the dial measuring gauge on the horizontal edge 3 on the device frame 2 is contacted with process flange 7 peripheries on being fixed on front ventilator rope connection 9, the flexible probe that is fixed on the dial measuring gauge 4 on the erection seat 1 contacts with the end face of process flange 7, rotation starts change speed gear box rope connection 8, two dial measuring gauges 3,4 do radially and end pulsation measurement at the circumference of process flange 7 respectively, adjust the spacer thickness and a left side of front ventilator bottom simultaneously, right position, behind the check screw of fastening front ventilator seat surrounding, guarantee between ventilating set axial line and the corresponding axial line of startup change speed gear box, right alignment is in the scope of process stipulation, and finish the location.
