Description

Vynález rieši nastavovací prípravok pre nastavenie režného nástroj a u sústruhov na žiadaný rozměr priamo na stroji.The invention provides an adjusting device for adjusting the cutting tool and lathes to the desired dimension directly on the machine.

Doposial’ používané metody a prostriedky nastavovania režného nástroj a sústruhov na rozměr možno rozdělit do troch skupin: nastavenie na skúšobný přechod; nastavovanie na kaliber-etalón a nastavovanie mimo stroj. Nastavovanie na skúšobný přechod používá sa u nerozmerového nástroj a skusmým nastavením na triesku, po zmeraní skutočného rozměru prevedie sa oprava nastavenia využitím noniusovej stupnice příslušného suportu. Nastavovanie na kaliber-etalón používá sa u nerozmerového alebo rozměrového a tvarového nástroj a, pričom kaliber má tvar obrobku. Nastavovanie mimo stroj používá sa v modemej konštrukcií obrábacích strojov, najma NC a produkčných typov, maj úcich účelovo konštruovanú nožovú hlavu a držiaky nástroj ov. Nastavovanie na skúšobný přechod a nastavovanie na etalon je pracné a málo přesné, čo má nepriaznivý dopad na produktivitu a kvalitu výroby. Nastavovanie mimo stroj sa využívá lén pri moderných konštrukciách obrábacích strojov.The methods and means used so far to adjust the cutting tool and lathes to the dimension can be divided into three groups: setup for trial transition; adjustment to caliber-etalon and adjustment outside the machine. Adjustment for the test transition is used for a non-dimensional tool and experimentally set to the chip, after measuring the actual dimension, the adjustment is made using the nonius scale of the respective slide. The caliber-et alone setting is used for non-dimensional or dimensional and shape tools a, the caliber having the shape of a workpiece. Off-machine adjustments are used in modem machine tool constructions, in particular NC and production types, having purpose-built cutter heads and tool holders. Setting up for the test transition and setting up for the standard is laborious and low precision, which has an adverse impact on productivity and production quality. Out-of-machine adjustment is used in modern machine tool designs.

Vyššie uvedené nedostatky sú odstránené nastavovacím prípravkom podía vynálezu, ktorého základom je nastavovací priečnik nesúci držiak so snímačom, například číselníkovým odchýlkomerom, posuvné uložený na vodiacej tyči pevne upevnenej v telese, ktoré je otočné uložené v upínacom puzdre. Os vodiacej tyče a os upínacieho puzdra sú navzájom kolmé.The above drawbacks are overcome by an adjusting device according to the invention based on an adjusting beam carrying a sensor holder, for example a dial gauge, slidably mounted on a guide rod fixedly mounted in a body which is rotatably mounted in a clamping sleeve. The axis of the guide rod and the axis of the chuck are perpendicular to each other.

Takýmto usporiadaním nastavovacieho přípravku sa dosiahne toho, že po upnutí upínacieho puzdra do skíúčovadla sústruhu, připadne do klieštín alebo medzi hroty, os vodiacej tyče, po ktorej sa móže presúvať nastavovací priečnik s upnutým dlžkovým snímačom, například číselníkovým odchýlkomerom, je kolmá na geometrickú os stroja (os rotácie vřetena) a je teda normálou vytváranej valcovej plochy a preto přestavováním priečnika je možné nastavovat hodnotu poloměru valcovej plochy vytváranej režným nástrojom. Nastavovací prípravok slúži pre nastavenie režného nástroj a na žiadaný rozměr s možnosťou vyeliminovania chyby v nastavení vzniklej excentricitou upnutia nastavovacieho přípravku a pre kontrolu správnosti výškového upnutia, režného nástroj a v nožovéj hlavě.By this arrangement of the adjusting device it is achieved that after clamping the chuck in the lathe chuck, falls into the ticks or between the tines, the axis of the guide bar on which the adjusting crossbar with the clamped length sensor can be moved, for example dial gauge, (axis of rotation of the spindle) and is thus a normal cylindrical surface to be formed, and therefore by adjusting the cross-member, it is possible to adjust the radius of the cylindrical surface produced by the cutting tool. The adjusting tool is used for adjusting the cutting tool and to the desired dimension with the possibility of eliminating the adjustment error due to the eccentricity of the clamping of the adjusting tool and for checking the correctness of the height clamping, the cutting tool and the cutter head.

Nového účinku sa dosahuje týmto nastavovacím prípravkom najma tým, že ním možno veími rýchlo a l’ahko nastavovat režný nástroj na rózne priemery, pričom dosahovaná presnosť nastavenia je na kvalitativně vyššej úrovni než u doteraz používaných metod, pričom obsluha tohto přípravku je nenáročná.The novel effect is achieved by this adjusting device, in particular by the fact that it is possible to adjust the cutting tool to different diameters very quickly and easily, and the achieved accuracy of adjustment is at a qualitatively higher level than the methods used up to now, and it is easy to operate.

Na pripojenom výkrese je znázorněný příklad prevedenia nastavovacieho přípravku podl’a vynálezu.The attached drawing shows an exemplary embodiment of an adjusting jig according to the invention.

Nastavovací priečnik 1 nesie držiak 2 a v ňom upevněný dlžkový snímač, například číselníkový odchýlkomer 15. Nastavovací priečnik 1 je posuvné uložený na vodiacej tyči 3, ktorá je pevne spojená s telesom přípravku 4 pomocou zverného spojenia. Teleso 4 je prostredníctvom čapu 5 otočné uložené v upínacom puzdre 6, v ložiskách 7. Nastavovací prípravok sa na sústruh upevňuje rovnakým sposobom ako obrobok (do sklúčo vadla klieštín medzi hroty) a vodiaca tyč 3 sa natočí tak, aby jej os bola rovnoběžná s upínacou plochou nástroj a. Po natočení vodiacej tyče a zaistení zvierkou 8 sa prevádza kontrola nulového nastavenia dlžkového snímača, například číselníkového odchýlkomera 15, pomocou nastavovacej mierky 14. V případe, ak nulové nastavenie snímača 15 má iba malú odchýlku, možno ho dojustovať pomocou nastavovacej skrutky 10. Kontrola nulového nastavenia snímača sa móže previesť aj mimo stroj. Natočením vodiacej tyče 3 v upínacom puzdre 6 o 90° voči východnej polohe, čo je umožněné uhlovým delením kotúča 9, a zaistení zvierkou 8, možno kontrolovat správnosť výškového nastavenia režného nástroja v nožovej hlavě. Po kontrole výškového upnutia nástroja sa nastavovací prípravok natočí do východzej polohy a v nej zaistí. Nastavovací priečnik 1 sa presunie po vodiacej tyči 3 do polohy odpovedajúcej poloměru obrátenej plochy a zaistí. Potom presunieme režný nástroj do takej polohy, aby dlžkový snímač například číselníkový odchýlkomer 15, ktorého merací dotyk je v styku s režným nástrojom, ukazoval žiadanú hodnotu, a tým prevedieme nastavenie režného nástroja na žiadaný rozměr. Ak sú velmi přísné požiadavky na presnosť nastavenia, vtedy případná excentricita osi vřetena sústruhu a osi nastavovacieho přípravku sa odstráni tým, že přetočením vřetena o 360° zistíme na snímači 15 dvojnásobná hodnotu excentricity, a na základe nej korigujeme nastavená hodnotu režného nástroja.The adjusting beam 1 carries a holder 2 and a length sensor mounted therein, for example a dial deflector 15. The adjusting beam 1 is slidably mounted on a guide rod 3 which is fixedly connected to the tool body 4 by means of a clamping connection. The body 4 is rotatably supported by a pin 5 in the clamping sleeve 6, in the bearings 7. The adjusting fixture is fixed to the lathe in the same manner as the workpiece (into the collet chuck between the tips) and the guide bar 3 is rotated so that its axis is parallel to the clamping flat tool a. After rotating the guide bar and locking it with a clamp 8, a zero gauge adjustment of the length sensor, for example a dial gauge 15, is carried out using an adjustment scale 14. In case the zero adjustment of the sensor 15 has only a slight deviation, it can be adjusted using an adjusting screw 10. the sensor can also be transferred outside the machine. By rotating the guide bar 3 in the clamping sleeve 6 by 90 ° relative to the east position, which is made possible by the angular separation of the disc 9, and secured by the clamp 8, the height adjustment of the cutting tool in the cutter head can be checked. After checking the height clamping of the tool, the adjusting tool is rotated to the starting position and locked in it. The adjusting beam 1 is moved along the guide rod 3 to a position corresponding to the radius of the inverted surface and locked. We then move the cutting tool to such a position that the length sensor, for example a dial gauge 15 whose measuring contact is in contact with the cutting tool, shows the setpoint, and thereby adjusting the cutting tool to the desired dimension. If there are very stringent accuracy requirements, then the eccentricity of the lathe spindle axis and the adjusting tool axis is eliminated by turning the spindle through 360 ° to detect a double eccentricity value on the sensor 15 and correct the set value of the cutting tool.

Nastavenie priečnika 1 na vodiacej tyči 3 do žiadanej polohy je možné previesť viacerými spósobmi, napr. podlá nastavovacích mierok ale z hl’adiska jednotnosti a přesnosti sa najviac hodia přesné guličky 11, umiestnené vo vrtaní vodiacej tyče 3. Nastavovací inkrement je daný priemerom guličiek 11a tento má byť v súlade s meracím rozsahom dlžkového snímača, například číselníkového odchýlkomeru 15. Nastavenie priečnika sa prevedie tým, že v danej polohe priečnika 1 sa zasunie západka 13, umiestnená v telese priečnika medzi příslušné dve guličky 11. Styk medzi guličkami a západkou zaručuje pružný člen, například pružina 12. Skrutka 10 je dorazom pre guličky 11, a preto je možné ňou previesť dojustovanie nulovej polohy snímača, například číselníkového odchýlkomera 15 pri kontrole nulového postavenia pomocou nastavovacej mierky 14.Adjusting the crossbar 1 on the guide rod 3 to the desired position can be accomplished in several ways, e.g. according to the measuring gauges, however, for the sake of uniformity and accuracy, the most precise balls 11 located in the bore of the guide rod 3 are most suitable. The adjustment increment is given by the diameter of the balls 11a and this is to be in accordance with the measuring range of the length sensor, e.g. This is accomplished by inserting, in a given position of the cross-member 1, a latch 13 disposed in the cross-member body between the respective two balls 11. Contact between the balls and the latch is ensured by a resilient member. with it, adjust the zero position of the sensor, for example a dial gauge 15 when checking the zero position by means of the adjusting scale 14.

Claims

An adjusting device characterized in that it is formed by a cross-member (1) which does not slide the holder (2) with a sensor, e.g. a dial deviation meter (15), which is slidably mounted on a guide (3) fixed in the body (4), which is rotatably mounted in the clamping sleeve (6), wherein the guide rod (3) and the axis of the clamping sleeve (6) are perpendicular to each other.

An adjusting device according to claim 1, characterized in that in the bore of the guide rod (3) a ball (11) is mounted, the bladder is pressed by a resilient member, e.g. a spring (12), on a latch (13) and a stop (10).

2 shows an example of an embodiment of an adjusting device according to the invention. The adjusting crossbar 1 carries a holder 2 and a length sensor attached thereto, for example a numerical deviation gauge 15. The adjusting crossbar 1 is slidably mounted on a guide rod 3 which is rigidly connected to the body of the fixture 4 by a clamping connection. The body 4 is pivotally mounted in the clamping sleeve 6 by means of a pin 5, in bearings 7. The adjusting means is fixed to the lathe in the same way as the workpiece (the clamp is inserted between the tines) and the guide rod 3 is rotated so that its axis is parallel to the clamping tool and After the guide rod has been rotated by the clamp locking device 8, a zero setting of the length sensor, for example a dial indicator 15, is carried out by means of an adjustment gauge 14. In case the zero adjustment of the sensor 15 has only a small deviation, it can be adjusted by means of an adjusting screw 10. sensor settings can also be transferred outside the machine. By rotating the guide 3 in the clamping sleeve 6 by 90 ° with respect to the east position, which is enabled by angular separation of the grip 9, and locking by the clamp 8, the correct height adjustment of the grinding tool in the knife head can be checked. After checking the height of the tool, the adjusting device is rotated in the starting position and locked in it. The adjusting crossbar 1 is moved along the guide bar 3 to a position corresponding to the radius of the inverted surface and secured. We then move the gray tool to such a position that the length sensor, for example, the dial gauge 15, whose contact is in contact with the gray tool, shows the desired value, thereby adjusting the overhead tool to the desired dimension. If the accuracy requirements are very strict, then the possible eccentricity of the spindle axis of the lathe and the adjusting tool axis is eliminated by rotating the spindle 360 ° to find twice the eccentricity value on the sensor 15, and based on the most corrected value of the gray tool. The adjustment of the crossbar 1 on the guide bar 3 to the desired position can be carried out in several ways, eg according to the adjustment scales, the most accurate ball 11 placed in the guide bar bore 3 is most suitable for uniformity and precision. The diameter of the balls 11a is to be in accordance with the measuring range of the length sensor, for example the dial indicator 15. The adjustment of the cross member is accomplished by inserting the latch 13 located in the crossbar between the two balls Stykmedzi. A ball 10 is provided by a resilient member, for example a spring 12. The screw 10 is a stopper of the ball 11, and therefore it is possible to carry out the zeroing of the sensor, for example, a dial gauge 15 in the zero position control by means of the adjusting scale.

3. An adjusting device according to claim 1, characterized in that when the measuring probe of the dial indicator (15) is set to the zero position, the body (4) is provided with a setting gauge (14) and a guide rod (3) with a stop, for example, by screw (10). 1 drawing
