Abstract

The utility model provides a quick measurement inspecting tool which adopts the comparing method; the inspecting tool is comprised of a inspecting tool body and a inspecting standard part; a below place of the inspecting tool body is provided with two locating V shape piece, to analog the common axial line of the main axle diameter which is near to the crank; another measuring moving V shape piece is connected with a guide piece, and can self-center with the connecting rod axial diameter; the moving V shape piece is provided with a feeler lever which is connected with a display; the display is provided with indicator clipping rod and bolts. The inspecting axle diameter and a central distance dimension of a inspecting standard part have high precision; before measuring the work-pieces, check the display zero-position with the inspecting standard part, then measure the work-pieces with the inspecting tool body, the difference between the display reading and the standard part reading is the error of the inspected position; the inspecting tool solves the problems of low inspecting efficiency and huge labor strength in the inspection with upper-flat-plate and ADCOLE crankshaft measuring machine, and provides a convenience for inspector quickly and reliably measuring the crank radius of the crankshaft.

Description

The throw of crank shaft cubing

Technical field

The utility model cubing belongs to explosive motor throw of crank shaft cubing, can detect the throw of crank shaft parameter fast, conveniently, reliably.

Background technology

The explosive motor throw of crank shaft is an important parameter of engine design, directly influence engine performance, detecting throw of crank shaft in test and batch process bent axle process is a necessary job, general throw of crank shaft detects adopt more and detects on flat board, its process is: flat board is carried and lifted to measured workpiece, and crank spindle directly is supported on two wishbones, measure on main shaft and footpath with band clock gauge height gauge, the common axis of adjusting two supporting spindle footpaths of bent axle is parallel to flat board, and write down the reading value of height gauge, again the crankshaft-link rod diameter of axle is forwarded to the highest or extreme lower position, measure and the note reading with band clock gauge height gauge, calculate the crank length value through data computation then.When measuring another crank length, repeat the above-mentioned course of work, use the plane-table operation method in the multi-cylinder throw of crank shaft detects, not only time-consuming but also labour intensity is big, measuring accuracy is not high yet; Bent axle is moved to crank shaft measurement machine or the measurement of three coordinate machine measuring chamber, though the measuring accuracy height,, efficient is low, does not catch up with the productive temp demand, and in many variety production line, it is big to detect investment with online automatic measurement machine, and floor area is big; The a tractor serves several purposes mensuration, it is long to adjust the measuring machine time, influences frequent many variety production beat.In production in enormous quantities, make product quality controlled, guarantee productive temp, a kind of quick, convenient, reliable cubing must be equipped with.

Summary of the invention

The technical solution of the utility model throw of crank shaft cubing is such: the purpose of the utility model cubing is to provide a kind of employing comparative measurement method to measure fast, before detecting workpiece, earlier the cubing body is positioned on the check and correction standard component, loads onto display and involutory zero-bit; Then, the cubing body is positioned on the measured workpiece measuring point, this moment cubing with two fixedly vee-block snap into directly outer round surface self-centering of crank spindle, the common axis of the adjacent main shaft diameter of simulation crankshaft crank is made orientation axis, the slip vee-block snaps into the self-centering of crankshaft-link rod outer round surface, and make linear slide, transmitting tested position error amount by feeler lever shows to display, correlative value i.e. error amount as can be known. and this cubing comprises cubing body and check and correction standard component, screw, handgrip A, handgrip B, a check and correction axle A, a check and correction axle B, base plate; The cubing body comprises cubing body plate, location vee-block, slip vee-block, orienting lug, tong-test ammeter bar, feeler lever.Location vee-block, right-hand member dress slip vee-block and orienting lug are housed below the cubing body plate, slip vee-block connection feeler lever, feeler lever is connected with display.Above the cubing body plate tong-test ammeter bar, screw, display are housed, handgrip A and handgrip B are equipped with in cubing body plate two ends.Connect the simulation crank spindle on the base plate of check and correction standard component and directly proofreading an A and simulation crankshaft-link rod diameter of axle check and correction axle B.Cubing body plate is a convex shape, and the V-arrangement face of vee-block is the 75-125 degree, V-arrangement face welding wimet, and the tong-test ammeter bar is a screw-driving resilient clamp display, feeler lever is a straight pin chamfered edge shape.

The advantage of this practical cubing is: (1). two fixedly vee-block self-centerings, bearing accuracy height; The self-centering of slip vee-block is accurate, and can linear slide, and it is bigger than swinging structure for measurement range, and the precision height is reliable; Vee-block V-arrangement locating surface all is welded with wimet, long service life.(2). the cubing body structure is simply light, the outer workpiece that detects of can onlinely reaching the standard grade.(3). easy to operate, fast, accurately and reliably, need only the cubing body be positioned over the tested position of workpiece can finish fast-individual crank length detects.
