Description

Accurate microhardness testers
Technical field
The utility model relates to a kind of material hardness detecting instrument, relates to the accurate microhardness testers that a kind of material hardness detects specifically.
Background technology
China's microhardness testers adopt always and regulate upper and lower method to regulate the distance of detected material and pressure head and eyepiece by screw mandrel.Because detected material impression will amplify 50-400 image doubly in the detection, therefore spindle arrangement except will be very high verticality, except the depth of parallelism, the precision of leading screw and axle sleeve directly affects picture quality, in current use procedure, often there is the problems such as figure line is unstable, shake, image definition is inadequate, seriously have impact on the accuracy of detection of microhardness testers.Shell due to microhardness testers adopt monoblock cast mode to ensure in housing processing the dimensional accuracy difficulty at each position is very large, because the verticality of housing, parallelism error are comparatively large, directly have influence on the overall precision of microhardness testers.
Summary of the invention
It is large that the purpose of this utility model is to provide a kind of Function Extension space, and precision performance is high, long service life, external form rational technology, processing, debugging, the simple accurate microhardness testers of mounting process.Mainly solving existing microhardness testers screw mandrel regulates the distance of detected material and pressure head and eyepiece to there is figure line shakiness, shake, technical matters that image definition is inadequate.
The technical solution of the utility model is: a kind of accurate microhardness testers, comprise base, fuselage and head, it is characterized in that: at fuselage inner chamber, base is fixed with column assembly, column assembly is fixed two line slide rails, line slide rail is provided with the slide block matched, slide block is fixed on head assembly, column assembly is fixed with elevating screw seat, hand wheel shaft is installed in elevating screw seat upper end, hand wheel shaft left end connects handwheel, hand wheel shaft right-hand member connects pinion wheel, elevating screw is installed in elevating screw seat lower end, elevating screw is socketed gear wheel, gear wheel engages with pinion wheel, elevating screw upper end spins screw, screw is fixed on screw mandrel Connection Block, screw mandrel Connection Block is fixed on head assembly rear end.
The utility model beneficial effect: because moving up and down of head assembly is along two high-precision line slide rail assemblies, head can be realized move up and down to adjust object lens, the distance of pressure head and detected material, problems such as eliminating the image shakiness because screw systems precision occurs not, shake, the precision of images is inadequate, because line slide rail component accuracy is high, obtain easily, therefore not high to technological requirement.Because upper and lower precision is ensured by line slide rail, elevating screw only plays transfer effect up and down, and when rotary handle, the upper and lower sliding motion of head assembly is steady, and control accuracy is high, is very beneficial for user's high precision fine tuning.Because base and column assembly are separable assembled structure, each split parts machining of base, platform, column assembly is simple, easily obtains high-precision type shape and positional precision, makes each parts accuracy guarantee become simple.Therefore after general assembly, overall precision has had guarantee.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation front view.
Fig. 2 is the cut-open view of Fig. 1.
Fig. 3 is the vertical view cutaway drawing of Fig. 1.
Fig. 4 is the rear cross sectional view of Fig. 1.
In figure: 1-base, 2-fuselage, 3-head, 4-column assembly, 5-line slide rail, 6-slide block, 7-head assembly, 8-elevating screw seat, 9-hand wheel shaft, 10-handwheel, 11-pinion wheel, 12-elevating screw, 13-gear wheel, 14-screw, 15-screw mandrel Connection Block.
Embodiment
With reference to Fig. 1, 2, 3, 4, a kind of accurate microhardness testers, comprise base 1, fuselage 2 and head 3, at fuselage 2 inner chamber, base 1 is fixed with column assembly 4 by screw, column assembly 4 is by screw being fixed two line slide rails 5, line slide rail 5 is provided with the slide block 6 matched, slide block 6 is fixed by screws on head assembly 7, column assembly 4 is fixed with elevating screw seat 8 by screw, hand wheel shaft 9 is installed in elevating screw seat 8 upper end, hand wheel shaft 9 left end connects handwheel 10, hand wheel shaft 9 right-hand member connects pinion wheel 11, elevating screw 12 is installed in elevating screw seat 8 lower end, elevating screw 12 is socketed gear wheel 13, gear wheel 13 engages with pinion wheel 11, elevating screw 12 upper end spins screw 14, screw 14 is fixed by screws on screw mandrel Connection Block 15, screw mandrel Connection Block is fixed by screws in head assembly 7 rear end.
When left rotation and right rotation handwheel 10, handwheel 10 is by driving pinion wheel 11 to rotate to hand wheel shaft 9, and pinion wheel 11 drives gear wheel 13, and gear wheel 13 drives elevating screw 12 to rotate.When elevating screw 12 left rotation and right rotation, screw 14 can drive head assembly 7 to slide up and down by leading screw Connection Block 15, and when handwheel 10 up time rotates, head assembly 7 moves upward, otherwise head assembly 7 moves downward.
