Abstract
The utility model discloses a piston stop port measuring mechanism, including a frame. A supporting shaft and a dial indicator are provided on the frame. The supporting shaft is slidably connected with symmetrically arranged two linkage systems with a same structure. A measuring terminal of the dial indicator is in top pressure fit between the two linkage systems. The linkage system comprises a moving block slidably connected onto the supporting shaft, an adjusting block slidably connected onto the moving block, a clamping seat detachably connected onto the adjusting block, and a measuring rod detachably connected onto the clamping seat. A pressure spring is connected between the moving block and the frame. The adjusting block is slidably connected onto the moving block through a guide rail of a swallowtail structure. The piston stop port measuring mechanism has a simple structure, is easy to operate, is convenient to adjust, is accurate in data display, and is suitable for the measuring of piston stop port diameters of different models and sizes.
Description
Technical field
The utility model relates to a kind of surveying instrument, relates in particular to a kind of piston seam measuring mechanism.
Background technology
Piston seam diameter dimension is the reference dimension in the machining piston process, therefore most important to the measurement of piston seam diameter dimension, the measuring method of prior art is to carry out piston seam diameter measurement from upper port with 0.02mm precision slide calliper rule, this measuring method degree of accuracy is low, error is larger, and everyone measurement result is also little consistent.
The utility model content
The utility model provides a kind of easy operating alive, measurement result piston seam measuring mechanism accurately in order to solve weak point of the prior art.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: piston seam measuring mechanism, comprise framework, framework is provided with a back shaft and a clock gauge, slidably connect on back shaft and be symmetrical arranged and structure is identical two cover interlock systems, the measurement terminal top of clock gauge is force-fitted between two cover interlock systems.
Described linked system comprises the movable block that is slidably connected on back shaft, be slidably connected at adjustment block on movable block, be detachably connected on the deck on adjustment block and be detachably connected on sounding rod on deck, be connected with extension spring between movable block and framework, adjustment block is slidably connected on movable block by the guide rail of dovetail structure, guide rail is parallel with back shaft, and movable block is provided with the dog screw for positioning adjusting block.
Described clock gauge is detachably connected on one and overlaps on the movable block of interlock system, and the measurement terminal of clock gauge is pushed up and is pressed on the movable block sidepiece of another set of linked system.
Described framework is provided with the stop screw that only moves along back shaft for limiting movable block.
Described deck removably connects by gib screw and adjustment block, and described sounding rod is located on deck by mounting screw.
Adopt technique scheme, have following beneficial effect;
1, when measuring, with the two cover interlock systems diameter of contact piston seam respectively, when the diameter of piston seam produces variable with the numerical value that sets in advance, by clock gauge, error numerical value is tested out.
2, the sounding rod of linked system adopts ruby to survey son, and sounding rod is installed on deck 1 by mounting screw; Satisfy the requirement of different hardness material measured piece by changing sounding rod.
3, deck is contained on adjustment block by gib screw, adjustment block is slidably connected on the dovetail structure that arranges on movable block, and regulates the relative position of adjustment block on guide rail by dog screw, is convenient for changing plurality of specifications, has improved and has regulated the speed.
4, deck is contained on movable block, has adapted to the hole measuring of different structure piston seam.
5, stop screw is positioned at optimum condition with movable block, can only limit movable block along the endwisely slipping of back shaft, thereby eliminate measuring error.
6, two cover interlock systems are housed on back shaft, two movable blocks are got back to initial point respectively under the extension spring effect, and the measurement terminal top of clock gauge is pressed on the movable block sidepiece of another set of linked system.The end of two sounding rods is contact piston seam diameter respectively, when the seam diameter dimension and given size is inconsistent when changing, can produce relative displacement between the end of two sounding rods, movable block moves along back shaft, the measurement terminal of clock gauge is pushed up presses or elongation, the clock gauge amount of movement, is presented on clock gauge (or sensor) display disc through the data acquisition of clock gauge (or sensor) through machinery and the result of difference operation, has so just improved measuring accuracy and dirigibility.
The utility model is simple in structure, simple to operate, easy to adjust, data show accurately, is applicable to the measurement of the piston seam diameter of different model, size.
