Abstract
The utility model discloses a groove-width check tool, comprising an amesdial, a slide bar and a carriage arranged on the slide bar. The carriage is provided with a rigid spring body which is divided into two parts of a fixing piece and a measuring piece by an elastic fixing part in the middle. One end of the measuring piece extends out of the carriage and a measuring ball is arranged on the end. The amesdial is arranged on the fixing piece with the measuring end of the amesdial contacting to the other end of the measuring piece. The utility model has the advantages that the groove width of the part can be checked conveniently by using the groove-width check tool which is simple to operate and has definite commonality, which ensures the accuracy of the experimental data and the production quality.
Description
Technical field
The utility model relates to a kind of measuring appliance, especially a kind of Groove-width check tool of measuring groove width.
Background technology
Usually detect the following several method of jump ring groove width of part: 1, detect shape and differentiated with model.2, detect the upper limit and the lower limit of jump ring groove width with the method for logical no-go gage.3, measure the jump ring groove width with improved vernier caliper or clock gauge.4, with apparatus measures jump ring groove widths such as projector.Because jump ring groove size is less, precision is higher, and all these methods detect the jump ring groove width, and inconvenience is arranged, as: can not accurately differentiate, maybe can not read concrete data, or measure inconvenience, precision is not enough, or detection speed waits slowly.This does the Cpk statistics to the data that requirement is arranged especially for the machine tool adjustment, makes troubles.
The utility model content
The utility model will solve the defective of above-mentioned prior art, and a kind of Groove-width check tool of special use is provided.
The utility model solves the technical scheme that its technical matters adopts.This Groove-width check tool comprises clock gauge, slide bar, is located at the balladeur train on the slide bar, and described balladeur train is provided with the stiffness spring body, and this stiffness spring body is divided into fixture and two parts of measuring piece by the elastic joint part of centre; One end of this measuring piece stretches out balladeur train and the end is provided with the survey ball; Clock gauge is located on the fixture, and it measures the other end that the end is butted on measuring piece.
The effect that the utility model is useful is: use the utility model can conveniently detect the part groove width, and simple to operate, have certain versatility, guarantee the accuracy of check data, guarantee product quality.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model is surveyed the structural representation of ball on groove top;
Fig. 3 is that the utility model is surveyed the structural representation of ball in the groove bottom.
Description of reference numerals: upper cap 1, slide bar 2, clock gauge 3, stop screw 4 switches handle 5, trip bolt 6, spring 7, stiffness spring body 8, balladeur train 9 is surveyed ball 10, workpiece 11, base 12, fixture 13, bolt 14, connecting portion 15, measuring piece 16.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
This Groove-width check tool comprises clock gauge 3, slide bar 2, is located at the balladeur train 9 on the slide bar 2.Slide bar 2 bottoms are fixedly connected on the base 12, and the upper end is provided with upper cap 1.Balladeur train 9 is provided with stiffness spring body 8, and this stiffness spring body 8 is divided into fixture 13 and 16 two parts of measuring piece by the elastic joint part 15 of centre; Connecting portion 15 is very thin, adds the toughness of steel, so measuring piece 16 can be that fulcrum rotates with connecting portion 15.One end of this measuring piece 16 stretches out balladeur train 9 and the end is provided with survey ball 10; Clock gauge 3 is located on the fixture 13, and it measures the other end that the end is butted on measuring piece 16.Be connected with back-moving spring 7 on the measuring piece 16, the other end of this spring 7 is fixed in the lower end of switching handle 5, switches handle 5 lower ends and is threadedly connected on the fixture 13.When spring 7 was in free state, measuring piece 16 was surveyed 10 at one end past upwarping of ball, and ergometry upwards.Rotate and switch handle 5, pulling spring 7 can make and survey 10 at one end past pressing down of ball, and ergometry is downward.Measuring piece 16 is connected with bolt 14, and described fixture 13 is provided with positioning screw 4, and the lower end of this positioning screw 4 is threaded with bolt 14.The distance of turn positioning screw 4 adjustable mounts 13 and measuring piece 16.Clock gauge 3 its measurement axis are located in the chute of fixture 13, and this chute is provided with the trip bolt 6 that cooperates with the clock gauge measurement axis.Like this, can move up and down the position of clock gauge 3, then with trip bolt 6 location.
Its work and measuring principle are: utilize standard component to adjust cubing, detect tested part again, clock gauge can accurately be read jump ring groove width data, simple and easy to use. its work and measuring process are: 1. rotate and switch handle 5 trip springs 7, make spring 7 be in free state, this moment, ergometry made progress, rotate the handwheel on the balladeur train 9, adjust the position of balladeur train 9 on slide bar 2, make survey ball 10 contact (see figure 2) with the upper surface of measured workpiece 11, and allow percentage gauge pressure about 0.15, with balladeur train 9 lockings, rotate dial plate and make dial gauge 3 pointers zero.2. rotate switching handle 5 pulling springs 7 and make dynamometry downward, survey ball 10 and contact (see figure 3) with measured workpiece 11 lower surfaces, at this moment, the reading of clock gauge 3 shows surveys the distance that ball 10 moves.Write down the reading a of table.3. groove width is d+a, and wherein d is for surveying bulb diameter.4. definite sphere diameter is measured d=exemplar groove width-a by 1 and 2 steps with master body.
