Description
Technical field
The utility model relates to a kind of cubing of automobile steering device screw rod trajectory measurement, belongs to steering gear screw rod appliance special for detecting technical field.
Background technology
Screw rod trajectory M value is the critical size of screw rod, and need 100% entirely to examine trajectory size in process, because trajectory is spiral trajectory, lead angle is 9.5 °, cannot go to measure by conventional method; If go to detect by three-dimensional, spended time is oversize, and cannot on-line checkingi, and the inspection frequency cannot meet the demands, and brings great difficulty to the detection in process.
Summary of the invention
The purpose of this utility model is, for above-mentioned the deficiencies in the prior art, there is provided one can detect screw rod trajectory M value at any time, reduce measuring error, the detection frequency is unrestricted, make inspection in processing become more accurate, convenient, and structure is simple, the cubing of the automobile steering device screw rod trajectory measurement of low cost of manufacture.
The utility model realizes above-mentioned purpose by the following technical solutions:
The cubing of this automobile steering device screw rod trajectory measurement is by showing chuck, movable measuring head, gauge stand, stirring handle, cover plate, measurer body, fixation measuring head and calibration bar construction, it is characterized in that: the bottom of measurer body side is provided with movable measuring head and gauge stand, the outside of movable measuring head is set with spring, spring housing is contained in gauge stand shrinkage pool, is provided with clock gauge outside gauge stand; The top of this side of measurer body is provided with one by straight pin and stirs handle, and the lower end of stirring handle is inserted in the through hole of movable measuring head; Fixation measuring head is all equipped with at the opposite side of measurer body and top, fixation measuring head by the screw rod of upper end and set nut fixing on the cover board, cover plate is packed on measurer body by screw.Described fixation measuring head and the front end of movable measuring head are provided with the steel ball that diameter is 7.144mm.
The utility model beneficial effect is compared with prior art:
The cubing of this automobile steering device screw rod trajectory measurement is by 2 fixation measuring heads and 1 movable measuring head, contact with screw rod trajectory to be checked rapidly, rotate drive activity measuring head by handle again to move left and right, movable measuring head and clock gauge contact, clock gauge directly reads trajectory M value.This detection tool structure is simple, easy to manufacture, and low cost of manufacture is convenient to use, and measures accurately, is specially adapted to automobile steering device screw rod trajectory M value and measures use.Solving existing employing three-dimensional, to detect spended time oversize, and cannot on-line checkingi, the problem that the inspection frequency cannot meet the demands.
Accompanying drawing explanation
Fig. 1 is a kind of main TV structure schematic diagram of cubing of automobile steering device screw rod trajectory measurement;
Structure vertical view when Fig. 2 is the utility model detection.
In figure: 1, show chuck, 2, movable measuring head, 3, spring, 4, gauge stand, 5, stir handle, 6, straight pin, 7, cover plate, 8, measurer body, 9, screw, 10, set nut, 11, fixation measuring head, 12, milled screw, 13, calibration rod, 14, clock gauge.
Embodiment
A kind of cubing of automobile steering device screw rod trajectory measurement, it by showing chuck 1, movable measuring head 2, gauge stand 4, stir handle 5, cover plate 6, measurer body 7, fixation measuring head 11 and calibration rod 13 and form, the bottom of measurer body 8 side is provided with movable measuring head 2 and gauge stand 4, the outside of movable measuring head 2 is set with spring 3, spring 3 is sleeved in the shrinkage pool of gauge stand 4, is provided with clock gauge 14 outside gauge stand 4; The top of this side of measurer body 8 is provided with one by straight pin 6 and stirs handle 5, and the lower end of stirring handle 5 is inserted in the through hole of movable measuring head 2; Fixation measuring head 11 is all equipped with at the opposite side of measurer body 8 and top, and fixation measuring head 11 is fixed on cover plate 7 by the screw rod of upper end and set nut 10, and cover plate 7 is packed on measurer body 8 by screw 9.Described fixation measuring head 11 and the front end of movable measuring head 2 are provided with the steel ball that diameter is 7.144mm.(see accompanying drawing 1 ~ 2).
The cubing of this automobile steering device screw rod trajectory measurement before detection, all needs first to use calibration rod 13 by cubing clock gauge 14 to zero at every turn.Stir handle 5 by rotation and make the outwards movement of movable measuring head 2, now screw rod to be detected is put into trajectory cubing, because the steel ball being provided with Φ 7.144 before fixation measuring head 11 and movable measuring head 2 is just in time tangent with trajectory, now unclamp and stir handle 5 and just can clamp screw rod to be measured, when rotating screw rod to be measured, movable measuring head 2 drives the indicators turn of clock gauge 14 when moving, can be read the M value of screw rod by the pointer of clock gauge beat.In actual applications, for the screw rod of different trajectory M value, only need the calibration rod 13 designing and producing corresponding trajectory M value, by calibration rod 13, cubing clock gauge 14 can be measured screw rod trajectory M value after zero.
The detection tool structure of this automobile steering device screw rod trajectory measurement is simple, manufacture easily, low cost of manufacture, solve the existing difficult problem that cannot detect on a production line, and measure accurately, fast, meet the requirement that trajectory 100% detects completely, effectively raise checkability, be specially adapted to the measurement of automobile steering device screw rod trajectory M value.
The above is preferred embodiment of the present utility model, above-mentioned illustrating does not do any pro forma restriction to flesh and blood of the present utility model, any simple modification that person of an ordinary skill in the technical field has done above embodiment according to technical spirit of the present utility model after having read this instructions or distortion, and the technology contents of above-mentioned announcement may be utilized to be changed or be modified to the Equivalent embodiments of equivalent variations, all still belong in the scope of technical solutions of the utility model, and do not deviate from essence of the present utility model and scope.
