Description
Technical field
The present invention relates to a kind of middle calipers, particularly a kind of measurement mechanism for detection of worm screw central diameter in automobile steering system.
Background technology
Automobile steering system mainly comprises steering wheel, input shaft, torque arm and power steering hydraulic system.The power steering valve of power steering hydraulic system comprises valve pocket and valve two parts, on valve pocket and spool, be equipped with oilhole, the oilhole of valve pocket and diverse location on spool is interconnected and can forms the different closed circuit of flow direction, spool and valve pocket generation relative motion, will change like this break-make relation of oil duct between valve pocket and spool and the flow direction of hydraulic oil, and then rotate towards different directions by hydraulic gear band motor car wheel.Steering wheel is connected with torque arm by input shaft, and the other end of torque arm is by turbine and worm mechanism and wheel.When rotating steering wheel, moment of torsion is passed on torque arm by input shaft, and torque arm is with motor car wheel left and right turn by turbine and worm structure.
In the production run of worm screw, in order to guarantee that the quality of worm screw need to monitor the central diameter of worm screw, the measurement of worm screw central diameter at present mainly adopts three skill of handling needles to detect.Three pin mensurations are a kind of methods of indirect measurement worm screw central diameter.During measurement, three precision metering pins very high, that diameter is identical are placed in the groove of tested worm screw, wherein two are placed in the groove that homonymy is adjacent, another root is placed in the middle groove of answering in contrast on opposite, then with the measurement instrument of measuring outside dimension, measures size as milscale, mechanical comparator, light compared with instrument, horizontal metroscope etc.According to calculation of parameter such as the pitch of tested worm screw, metering pin diameters, go out the central diameter of worm screw again.
The central diameter that adopts three pin mensurations to measure worm screw is at present metering pin to be placed on respectively in the groove of worm screw both sides by operating personnel, then by the microdrum of rotating lever milscale, two gauge heads are contacted with the metering pin of both sides respectively, thereby read the central diameter value of tested worm screw, adopt the inconvenience operating in this way very, measuring speed is slower, for new hand, sometimes need two people to coordinate just and can complete, bring certain puzzlement so just to the central diameter detection of worm screw, particularly when needs mass detection, just need to there is more testing staff to assist, the production cost of enterprise is increased.
Summary of the invention
The shortcoming of prior art, the object of the present invention is to provide calipers in a kind of worm screw simple in structure, easy to use in view of the above.
For achieving the above object and other relevant objects, the invention provides calipers in a kind of worm screw, it comprises a base plate, described base plate is provided with the first metering pin and the second metering pin being arranged in parallel, described base plate top is provided with a dial gauge, the sounding rod of described dial gauge is connected with the 3rd metering pin by a connection piece, and described the 3rd metering pin is horizontally disposed with.
Preferably, described web member is connected with described sounding rod is rotatable.
Preferably, the two ends of described the first metering pin, the second metering pin are all supported on slide block, and described slide block and described base plate are slidably connected.
Preferably, described the first metering pin, the second metering pin are connected in described slide block.
Preferably, described dial gauge is connected with described base plate by a support.
Preferably, described web member is provided with two web joints that are oppositely arranged, the two ends of described the 3rd metering pin respectively with two web joint clampings.
As mentioned above, in worm screw of the present invention, calipers has following beneficial effect: in this worm screw, calipers only need be placed on worm screw on base plate in use, the first metering pin, the second metering pin on base plate are placed in two grooves that worm screw is adjacent, and then will the 3rd metering pin be placed in a groove of worm screw opposite side, read the reading of dial gauge and according to the parameter of the pitch of the diameter of metering pin, groove, just can calculate the central diameter size of this worm screw.Adopt calipers in this worm screw to the central diameter of worm screw, to measure fast, operate very convenient, be not easy to be subject to the impact of human factor, can effectively improve measuring accuracy and the measuring speed of worm screw central diameter.

Embodiment
By particular specific embodiment explanation embodiments of the present invention, person skilled in the art scholar can understand other advantages of the present invention and effect easily by the disclosed content of this instructions below.
Refer to Fig. 1,2.Notice, appended graphic the illustrated structure of this instructions, ratio, size etc., equal contents in order to coordinate instructions to disclose only, for person skilled in the art scholar, understand and read, not in order to limit the enforceable qualifications of the present invention, therefore the technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, not affecting under the effect that the present invention can produce and the object that can reach, all should still drop on disclosed technology contents and obtain in the scope that can contain.Simultaneously, in this instructions, quote as " on ", the term of D score, " left side ", " right side ", " centre " and " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the present invention, the change of its relativeness or adjustment, under without essence change technology contents, when being also considered as the enforceable category of the present invention.
As shown in Figure 1, 2, the invention provides calipers in a kind of worm screw, this measurement mechanism comprises a base plate 1, on base plate 1, be provided with the first metering pin 8 and the second metering pin 9 that are arranged in parallel, above base plate 1, be provided with a dial gauge 3, dial gauge 3 is connected with base plate 1 by support 2, and the sounding rod 4 of dial gauge 3 is connected with a connection piece 5 through the top of support 2.The two ends that the bottom of web member 5 is provided with two web joint being oppositely arranged 6, the three metering pins 7 are connected with two web joints 6, and the 3rd metering pin 7 is horizontally disposed with.
