Clamp-type mills fast
The utility model relates to the quick milling machine of clamp-type that industry laboratories such as a kind of small-sized milling device, especially a kind of metallurgy are used, and belongs to the machining equipment technical field.
Metallurgy industry need mill the oxide layer of sample surfaces etc. before the spectrum that carries out sample, Metallographic Analysis, expose inner normal structure.This process is often carried out in fusion process, therefore requires to finish rapidly.
Understand according to the applicant, the lathe bed of existing this type of milling device top is supported with the horizontal lead screw of big driven by servomotor at present, this horizontal lead screw is connected with spindle drum by screw pair, spindle drum constitutes rotatable vertical moving sets with the operator head, operator head is connected with main motor on being placed in spindle drum by the band transmission, down-feed screw is equipped with in its upper end, this down-feed screw and the nut engagement that is fixed on the spindle drum, simultaneously by the band transmission be placed in the little servomotor of main shaft on being present and be connected.When little servomotor rotates, can regulate the milling surplus by the moving operator of a down-feed screw subband length feed; When main motor rotates, will drive the milling cutter rotation by the band transmission; When big servomotor rotates, will realize crossing feed by whole the moving of the moving spindle drum of horizontal lead screw subband, finish the milling of workpiece.
Yet the fast and reliable clamping of sample to be processed fails to see disclosed possible technique scheme.
The utility model content
The purpose of this utility model is: propose a kind ofly to have the clamp-type that automatically fast clamps function and mill fast, thereby better meet the needs of the quick milling sample of industry such as metallurgy.
In order to reach above purpose, the lathe bed below that the utility model clamp-type mills fast is holder fixedly, the top is supported with the horizontal lead screw of big driven by servomotor, this horizontal lead screw is connected with spindle drum by screw pair, spindle drum and lathe bed horizontal rail constitute moving sets, and constitute a rotatable vertical moving sets with operator head, operator head is connected with main motor on being placed in spindle drum by the band transmission, down-feed screw is equipped with in its upper end, this down-feed screw and the nut engagement that is fixed on the spindle drum, simultaneously by the band transmission be placed in the little servomotor of main shaft on being present and be connected.In addition, the clamping cylinder is equipped with in the below of lathe bed, and the push rod termination of this cylinder is fixed with tooth bar, this tooth bar and the screw rod end tooth wheel engagement that is supported on the holder, be shaped on positive left-hand thread on this screw rod, respectively with two side bitting clamps on nut engagement, two clamps move horizontally pair with the holder formation.
Like this, of the present utility model milling fast except having original milling function, when the clamping cylinder ejected push rod, the rack drives gear rotated, and then drive two clamps respectively by reverse-flighted screw and relatively move, thereby realize clamping fast automatically the action of sample test specimen.
Obviously, behind employing the utility model, the more perfect functions of milling fast, the process operation automaticity is higher, clamps more reliably, changes the original mode that grinds sample, fast, environmental protection, guarantee sample cleaning, thereby can better meet the breadboard needs of industry such as metallurgy.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the right view (opening case) of Fig. 1.
The specific embodiment
The clamp-type of present embodiment mills as depicted in figs. 1 and 2 fast, lathe bed 25 belows are holder 26 fixedly, the horizontal lead screw 5 that big servomotor 23 drives by synchronizing wheel 24 and synchronous pulley 4 is supported in the top, this horizontal lead screw 5 is connected with spindle drum 10 by screw pair, and spindle drum 10 constitutes moving sets with upper and lower two horizontal rail 28 of lathe bed.Therefore, spindle drum 10 can be in the drive of servomotor 23 and screw pair, and along continuous straight runs moves, and realizes the cutting feed.
Operator 27 is installed in the upper and lower sleeve of spindle drum 10, constitutes a rotatable vertical moving sets with operator 27, operator 27 is connected with the main motor 11 that is placed in the spindle drum rear side by the band transmission, and down-feed screw 9 is housed on it.This down-feed screw and the nut engagement that is fixed on the spindle drum 10 are simultaneously by being connected with synchronizing wheel 14 on being placed in little servomotor 13 output shafts of main shaft on being present with 15 transmissions synchronously.After main motor 11 started, operator 27 milling cutter that can drive the lower end rotated, and by the drive of little servomotor 13 and the transmission of down-feed screw, can control the operator head and be elevated to the desired height position.
The below of lathe bed 25 is equipped with and is clamped cylinder 1, and the push rod termination of this cylinder is fixed with horizontal rack 2, this tooth bar and end gear 3 engagements that are supported on the screw rod 19 on the holder 26.Be shaped on positive left-hand thread on this screw rod, respectively with both sides 16 clamps on nut engagement, two clamps move horizontally pair with the holder formation.Therefore, after starting cylinder 1, push rod drives screw rod 19 and rotates by tooth bar 2 and gear 3, and then drives 16 motions of two clamps by screw thread pair, clamps the test specimen sample automatically.
In addition, also be equipped with below holder and heighten drive motors 21, the output shaft of this motor is by the engagement of the nut on vertical screw 20 and the lower cushion block 17, and this lower cushion block is between two clamps 16.After bed hedgehopping drive motors 21 starts, can drive lower cushion block 17 as required by vertical screw 20 and be elevated to correct position, thereby support the test specimen sample, obtain suitable milling surplus.
As can be seen, present embodiment to mill transmission fast reasonable, design perfectly, can reliably realize clamping fast automatically, therefore can satisfy the needs of the quick milling sample in industry laboratory such as metallurgy.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
