The beneficial effects of the utility model are: during use, in pin shaft hole on centre bore and the tool-post structure of blade, install bearing pin, being bolted structure will hold out against voussoir and be fixed on gradually on tool-post structure, in the fixation procedure that holds out against voussoir, be subject to wedge slope effect, hold out against voussoir gradually towards blade movement, until hold out against the outer peripheral face top interference fit of top pressure surface and the blade of voussoir, blade is at bearing pin with hold out against under the acting in conjunction of voussoir clamped fixing like this, when needs removal of inserts, only need unscrew a little bolt in bolt fastening structure makes to hold out against voussoir and no longer holds out against blade, blade can be by directly lifting down on bearing pin, when needs are installed again, directly blade sleeve is loaded on bearing pin, the bolt screwing a little in bolt fastening structure makes withstanding tight block hold out against blade, just completed the installation of blade, in the dismounting and installation process of blade, only need to unscrew a little, screw bolt, and do not need bolt all to screw out, the installation of blade, dismantle all very convenient.
Accompanying drawing explanation
Fig. 1 is the use state diagram of an embodiment of the present utility model;
Fig. 2 is the structural representation of Fig. 1 intermediate slide body;
Fig. 3 is the structural representation that holds out against voussoir in Fig. 1;
Fig. 4 is the structural representation of Fig. 1 Intermediate gasket;
Fig. 5 is the structural representation of blade in Fig. 1.
The specific embodiment
A kind of embodiment of turning tool rest is as shown in Fig. 1 ~ 5: the tool-post structure 9 that comprises rod-like structure, the front end of tool-post structure is provided with step groove, step groove comprises blade installation slot part 4 and voussoir mounting groove part 7, the bottom land of voussoir mounting groove part is higher than the bottom land of blade installation slot part, wherein the rear side outer peripheral face shape adaptation of the rear side cell wall shape of blade installation slot part and blade, is provided with for the pin shaft hole corresponding with the centre bore 1-1 of blade 1 11 on the bottom land of blade installation slot part.The rear side cell wall of voussoir mounting groove part forms wedge slope 8, wedge slope has the fixing wedge surface towards pin shaft hole, in voussoir mounting groove part, guiding is equipped with and holds out against voussoir 6, holding out against voussoir has and the movable wedge surface of fixing wedge surface gradient adaptation, hold out against on voussoir in a side opposing with movable wedge surface, be provided with for the top pressure surface 13 of the outer peripheral face top interference fit of blade, the respective side outer peripheral face shape adaptation of the shape of top pressure surface and blade, the blade side of being plate structure in the present embodiment, therefore the shape of the rear side cell wall of blade installation slot part and the shape of top pressure surface are V-arrangement.Turning tool rest also comprises that realization holds out against voussoir and is fixed on the bolt fastening structure on tool-post structure, bolt fastening structure comprises the screwed hole 10 being opened on the bolt penetration hole 12 holding out against on voussoir and the bottom land that is opened in voussoir mounting groove part, bolt hole is corresponding with screwed hole, in bolt penetration hole and screwed hole, be coated with bolt (not shown), on fore-and-aft direction, between bolt and the hole wall of bolt penetration hole, there is free gap.
When reality is used, need below blade, pad dress pad, pad 3 and blade 1 are set on bearing pin 2, then screw bolt, bolt is in the process screwing, holding out against voussoir moved by wedge slope effect forward, top pressure surface gradually hold out against blade outer peripheral face, at bearing pin with hold out against under the acting in conjunction of voussoir, blade is clamped fixing, when needs removal of inserts, only need unscrew a little bolt.Employing holds out against voussoir and holds out against the structure of blade, makes that blade is installed, convenient disassembly, and the setting of mounting groove simultaneously, has realized blade, held out against the inserted fixing of voussoir, and stability, reliability are stronger, working (machining) efficiency and machining accuracy while greatly promoting lathe tool processing.
In other embodiment of the present utility model: the shape of top pressure surface can be not and the respective side outer peripheral face shape adaptation of blade yet, such as arranging on blade and the adaptive top pressure surface of top pressure surface shape adaptation; The shape of tool-post structure can be also dish type or other shape; The screwed hole holding out against on bolt penetration hole and the tool-post structure on voussoir can also not established, now bolt fastening structure can be the following form that arranges, bolt fastening structure comprises for press-fiting in the pressing plate that holds out against briquetting upper end, the two ends of pressing plate are connected with tool-post structure by bolt, when needs blade holds out against, bolt band dynamic pressure plate presses down and holds out against voussoir, hold out against voussoir and will under wedge slope effect, towards insert orientation motion, hold out against blade, when needs removal of inserts, unscrew a little bolt and can realize the dismounting of blade; The bottom land of voussoir mounting groove part and the bottom land of blade installation slot part also can contourly arrange, and now do not need to arrange pad; When blade is other shapes such as rhombus, square, circular, triangle, the rear side cell wall shape of the shape of top pressure surface and blade installation slot part should adapt to adjust; Wedge slope also can be can't help the rear side trough wall surface of voussoir mounting groove part and be formed, such as wedge slope is separately set on the upper surface of tool-post structure.
