Abstract
The utility model relates to a brush holder pressure detection instrument, and relates to a detection instrument for detecting the pressure of the brush holder on the carbon brush, which aims at resolving the weaknesses of the known brush holder pressure detection instrument that the precision is low, the detected parameter is incorrect, the pressure of the pressing finger on the carbon brush cannot be really reflected, and the like, and the accidents such as the ring fire of the motor commutator is easy to be caused. The brush holder pressure detection instrument comprises a work platform, an installation board, a bolt and a scale, which is characterized in that an electronic scale is arranged on the lower plane of the work platform, and the electronic scale is provided with a transferring block, and the upper end of the transferring block is movably arranged inside a shaft hole on the upper plane of the work platform. The brush holder pressure detection instrument has high detection precision; for the pressure of the pressing finger is transferred to the electronic scale through the carbon brush, the contact point between the pressing finger and the carbon brush is superposed on to the detection point; and the pressing finger is contacted with the carbon brush during the detection of the brush holder pressure detection instrument, so that the data reflected by the electronic scale is ensured to be real and reliable, thereby preventing the accidents caused by the overlarge or undersize pressure.
Description
Technical field
The utility model relates to a kind of motor repair detecting instrument, relates to specifically detecting the detector of brush carrier to carbon brush pressure.
Background technology
In order to detect the pressure of brush carrier, generally adopt the brush spring pressure detecting instrument that spring pressure is detected in the brush carrier manufacturing assembling process to carbon brush.Traditional brush carrier pressure detecting instrument as shown in Figure 1, it mainly is made up of worktable 1, installing plate 2, bolt 3, spring balance 5; The course of work is: at first detected brush carrier 6 is fixed on the installing plate 2 by bolt 3, the below of brush carrier 6 and worktable 1 table top contact and parallel, carbon brush 4 is contained in brush carrier 6 square grooves, the pressure spring 9 of brush carrier 6 promote end fingers 7 around axle 8 rotate counterclockwise, till end finger 7 is pressed onto carbon brush 4, the hook of spring balance 5 is hung on the end finger 7, with hand spring balance 5 is upwards carried, make end finger 7 have trace to separate with carbon brush 4, the pressure of spring balance 5 shows this moment be the pressure of 7 pairs of carbon brush 4 of end finger, i.e. the pressure of 6 pairs of carbon brush 4 of brush carrier; Its shortcoming is: 1. since the assembling of traditional brush carrier pressure detecting instrument be spring balance, so precision is low, accurate inadequately; 2. traditional brush carrier pressure detecting instrument is because structure is limit, and the position and the end finger 7 that hang on the end finger 7 at detection medi-spring scale 5 are not same points with carbon brush 4 position contacting, so detected parameter is inaccurate; 3. with hand spring balance 5 is upwards drawn in detecting, owing to be manually-operated, 7 pairs of carbon brush 4 pressure directions of direction of pull and end finger can not absolute parallel, has influenced accuracy of detection; End finger 7 is that trace separates with carbon brush 4 when 4. detecting, so pressure that can not 7 pairs of carbon brush 4 of actual response end finger; Owing to there is an above defective, therefore cause the generation of accident such as engine commutator ring fire easily.
Summary of the invention
The purpose of this utility model is at above-mentioned deficiency, and a kind of accuracy of detection height that proposes makes end finger overlap with the contact point and the check point of carbon brush, detects accurately, truly reflects the brush carrier pressure detecting instrument of end finger to carbon brush pressure.
Technical solution of the present utility model is: the brush carrier pressure detecting instrument comprises worktable, installing plate, bolt and scale, it is characterized in that: an electronic scales is housed on the lower plane of worktable, electronic scales is provided with one and transmits piece, and the upper end of transmitting piece is movably connected on the worktable in the axis hole on the plane.
In the utility model technical solution on the said worktable axis hole on the plane be located on the last plane of installing plate vertical plane one side worktable.
Said worktable lower plane and last plane parallel in the utility model technical solution.
Therefore the utility model has improved accuracy of detection owing to adopt electronic scales to replace spring balance; The utility model is because the pressure of end finger is to be delivered on the electronic scales by carbon brush, end finger is overlapped with the contact point and the check point of carbon brush, the scale pan of electronic scales keeps vertical with the end finger pressure direction, brush carrier pressure detecting instrument end finger when detecting contacts with carbon brush, therefore guaranteed that end finger is to come out by the electronic scales actual response to the pressure of carbon brush, so it is accurate to detect the numerical value of brush carrier pressure, thereby can in time pinpoint the problems, in time solve, therefore avoided owing to the excessive or too small generation that causes accident such as engine commutator ring fire of pressure.
Description of drawings
Fig. 1 is the structural representation of known brush carrier pressure detecting instrument;
Fig. 2 is a structural representation of the present utility model.
Embodiment
As shown in Figure 2, the utility model mainly contains worktable 1, installing plate 2, bolt 3, electronic scales 5 and transmits piece 10 and form, installing plate 2 is made of orthogonal two planes, one of them vertical plane is fixed by bolts on the worktable 1, another vertical plane is vertical with worktable 1, have bolt 3 on this vertical plane, constitute the work installing mechanism by worktable 1, installing plate 2 and bolt 3, electronic scales 5 is installed on the lower plane 11 of worktable 1, the lower plane 11 and the last plane parallel of worktable 1, parallel to guarantee that electronic scales 5 is installed its scale pan of back with the pressure direction of end finger 7; Transmit piece 10 being equipped with one on the scale pan of electronic scales 5 and the worktable 1 between the plane, transmitting piece 10 is movably connected on the worktable 1 in the axis hole on the plane, this axis hole is located on the last plane of installing plate 2 vertical planes one side worktable 1, when the brush carrier pressure detecting instrument was worked, carbon piece 4 can transfer the pressure on the electronic scales 5 by transmitting piece 10; Principle of work is: at first detected brush carrier 6 is fixed on the installing plate 2 by bolt 3, the below of brush carrier 6 and worktable 1 table top contact and parallel, carbon brush 4 is contained in brush carrier 6 square grooves, the pressure spring 9 of brush carrier 6 promote end fingers 7 around axle 8 rotate counterclockwise, till end finger 7 is pressed onto carbon brush 4, carbon brush 4 passes to pressure on electronic scales 5 scales pan by transmitting piece 10, reading on the electronic scales 5 is the pressure of 7 pairs of carbon brush 4 of end finger.
