Abstract
Disclosed in the utility model is a lifting mechanism of a steel ball measuring instrument. The lifting mechanism comprises a tooth bar arranged at an adjusting seat and a gear wheel pivoted at a support arm, wherein the gear wheel and the tooth bar are engaged. A lifting knob is connected to the gear wheel. According to the structure, when steel balls with different specifications and dimensions are tested, the lifting knob rotates to drive the gear wheel to make rotation, so that the tooth bar goes up or descends; and a lifting probe is driven by the adjusting seat to carry out testing and adjusting. Therefore, the whole process can be carried out conveniently and rapidly; and the work efficiency is improved.
Description
Technical field
The utility model relates to a kind of measuring instrument, particularly a kind of accurate steel balls measuring instrument elevating mechanism.
Background technology
The size of accurate steel balls is very little, have even less than a millimeter, thereby be very difficult for the measurement of steel ball size, general measuring method was as follows in the past: a locking pin first is set in bottom, be provided with surveyingpin directly over locking pin, be provided with two subsidiary heads with the locking pin spatial vertical, accurate steel balls can only be picked up the end that is placed into locking pin by craft, and put on right position, by two subsidiary head location, then measure the diameter of steel ball by the measuring sonde of staff control survey pin, in said process, not only place and ajust steel ball position difficulty, need the cost plenty of time, and the temperature of staff also can cause the heat effect that rises to accurate steel balls, thereby cause measurement size that error is arranged, thereby the measuring instrument that the applicant has designed a kind of accurate steel balls is eliminated above-mentioned defect, the elevating mechanism of the measuring instrument that the application is accurate steel balls.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of elevating mechanism of surveying instrument of conveniently precise engineering surveying steel ball.
The utility model solves the technical scheme that its technical matters adopts:
A kind of steel ball measuring instrument elevating mechanism, it is characterized in that: comprise support, support is provided with measures platen and sway brace, sway brace is provided with adjustment seat, be fixed with high accuracy displacement sensor on adjustment seat, and be provided with the elevating mechanism that can make the adjustment seat lifting between sway brace and adjustment seat, described elevating mechanism comprises and is arranged at the tooth bar on adjustment seat and is hubbed at the gear on sway brace, and this wheel and rack engagement, be connected with the lifting knob on described gear.
Described sway brace end is provided with contiguous block, contiguous block is provided with dovetail groove, and the bottom surface of dovetail groove is provided with the tooth bar holding tank, and described tooth bar is positioned at the tooth bar holding tank, be provided with the dovetail slide block coordinated with dovetail groove between described tooth bar and adjustment seat, and tooth bar is fixed on adjustment seat by the dovetail slide block.
Described adjustment seat is provided with the set lever that can make adjustment seat and contiguous block locking.
Described lifting knob is relatively arranged on the gear both sides.
The beneficial effects of the utility model are: this elevating mechanism comprises and is arranged at the tooth bar on adjustment seat and is hubbed at the gear on sway brace, and this wheel and rack engagement, be connected with the lifting knob on described gear, by said structure, during the steel ball of the size of test different size, by turn lifting knob driven gear, rotate, thereby make tooth bar increase or descend, drive the lifting probe by adjustment seat and test adjustment, said process is convenient and swift, has improved work efficiency.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is whole vertical view of the present utility model;
