Abstract

The utility model discloses a tool post of a heavy cutter knife. The body of the tool post comprises a plurality of locating surfaces in location fit with the tool carrier of a lathe; screw holes (11) corresponding to cutter mounting holes are formed at intervals in the longitudinal direction along the cutter clamping surfaces (10) of the locating surfaces; screw holes (12) are formed at intervals in the longitudinal direction along the inner sides of the cutter clamping surfaces (10), where locating wedge blocks (20) are also mounted through bolts; and the locating wedge blocks (20) are provided with wedge-shaped bevels which are matched with the bottom of a cutter. The tool post has excellent rigidity and precision, meets the requirement of crankshaft processing for precision, effectively eliminates accumulated errors existing in the process of using and assembling the cutter, and ensures very high precision of the entire cutter and quick change.

Description

The heavy type cutting tools tool rest

Technical field

The utility model relates to the tool rest that is used to install lathe tool, particularly a kind of tool rest that is used to install heavy type cutting tools.

Background technology

Bent axle is regarded as the heart of marine diesel as the critical component of marine engine, to the crucial effects that plays of boats and ships.Because its weight is big, machining accuracy is high, manufacture difficulty is high, thereby " whether possess bent axle manufacturing energy, represented the shipbuilding level of a country to a certain extent " commonly used in the industry, illustrate the crank axle for vessel manufacturing technology in the importance of shipbuilding industry.At present Japan, Korea S, Spain etc. a few possess the manufacturing argosy and monopolizing crankshaft used for large boat market in the world with state's every household degree of half built-up crank shaft ability.

The bent axle manufacturing has complex structure, (size of connecting rod neck is IT6～IT7 several times for production lot required precision height, circularity≤0.005mm, the characteristics of surface roughness Ra 0.2～Ra0.5), the technology that goes out to rough mill the back grinding is earlier still generally adopted in processing at the end of bent axle at present, and therefore last grinding is particularly important for the precision of bent axle.For satisfying the processing request that bent axle improves day by day, good requirement has been proposed crankshaft grinding machine.Modern crankshaft grinding machine also requires to have very high grinding efficiency and more flexible except the very high machining accuracy that very high static state, dynamic rate will be arranged.Therefore, the technology of existing processing low-speed machine bent axle is not only to the requirement height of grinding machine, and process velocity is very slow, and processing a bent axle usually needs 35～45 days.

For improving the production efficiency of bent axle processing significantly under the prerequisite of the required precision of satisfying bent axle processing, the applicant discloses a kind of lathe tool that is used for the factory ship with the low-speed machine bent axle in application number is the specification of 200820063829.6 utility application.The application of this heavy type cutting tools is to replace grinding with turnning and milling, and process an identical bent axle only needs 15 days time, compares with grinding about working (machining) efficiency raising twice, thereby can reduce the production cost of marine low-speed machine crankshaft significantly; The machining accuracy height, processing back workpiece surface roughness can reach Ra0.2～Ra0.4, and diameter of axle machining accuracy can reach ± 0.05mm, all is higher than the precision that grinding can reach.

The tool rest that this heavy type cutting tools is installed on the lathe saddle should have extraordinary rigidity and precision, to satisfy the required precision of energy bent axle processing.In addition, owing to the diversity and the particularity of bent axle processing, need to change the tool rest of a lot of different sizes in the process, so tool rest should have fast transsexual structure.The tool rest of existing lathe can't satisfy the above-mentioned requirements of this heavy type cutting tools.

The utility model content

Technical problem to be solved in the utility model provides a kind of heavy type cutting tools tool rest, and this tool rest has extraordinary rigidity and precision, to satisfy the required precision of energy bent axle processing.

The technical scheme that its technical problem that solves the utility model adopts is: heavy type cutting tools tool rest of the present utility model, it is characterized in that: this tool rest body has a plurality of the mistake with lathe saddle and locatees the locating surface that cooperates, and its cutter clamping face upper edge longitudinal separation is provided with and the corresponding screw of cutter installing hole.

The inboard of described cutter clamping face longitudinally is arranged at intervals with screw, and the location voussoir is installed by bolt, this location voussoir has the wedge shape inclined-plane that matches with the cutter bottom, can eliminate cutter effectively by this location voussoir and in use, assembling process, have cumulative errors, make whole cutter reach unusual precision, thereby thereby satisfy can bent axle processing required precision.

Offer the T type groove of longitudinal extension on the sidewall on the described tool rest body.

The beneficial effects of the utility model are, have extraordinary rigidity and precision, can satisfy the required precision of bent axle processing; Can eliminate cutter effectively and in use, assembling process, have cumulative errors, make whole cutter reach very high precision; Have good transsexual soon.

Description of drawings

This specification comprises following two width of cloth accompanying drawings:

Fig. 1 is the front view of the utility model heavy type cutting tools with tool rest;

Fig. 2 is the cross-sectional view of the utility model heavy type cutting tools with tool rest;

Parts, toponym and pairing mark among the figure: cutter clamping face 10, screw 11, screw 12, T type groove 13, location voussoir 20, locating surface A, locating surface B, locating surface C, locating surface D, locating surface E.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

See figures.1.and.2, heavy type cutting tools tool rest of the present utility model, its tool rest body have a plurality of the mistake with lathe saddle and locate the locating surface that cooperates, as in by the specific embodiment shown in Fig. 2, the quantity of locating surface is five, i.e. locating surface A, B, C, D, E.Cutter clamping face 10 upper edge longitudinal separations are provided with and the corresponding screw 11 of cutter installing hole, and cutter is fixed on the cutter clamping face 10 by bolt.Guarantee that by a plurality of high-precision fixed plane A, B, C, D, E tool rest has extraordinary rigidity and precision, and the high-precision form and position tolerance of employing between locating surface A, B, C, D, E and the cutter clamping face 10, guarantee the high accuracy of cutter, thereby can satisfy the high-precision requirement of bent axle processing.

With reference to Fig. 1, the inboard of described cutter clamping face 10 longitudinally is arranged at intervals with screw 12, with reference to Fig. 2, by bolt location voussoir 20 is installed, and this location voussoir 20 has the wedge shape inclined-plane that matches with the cutter bottom.The effect of location voussoir 10 is to eliminate cutter to have cumulative errors in use, assembling process, makes whole cutter reach very high precision, thus thereby the required precision of satisfied energy bent axle processing.

Owing to the diversity and the particularity of work piece, in the bent axle process, need to change the tool rest of a lot of different sizes.Transsexual soon for realizing tool rest, with reference to Fig. 2, offer the T type groove 13 of longitudinal extension on the sidewall on the described tool rest body, this T type groove 13 matches with pneuma-lock mechanism on the lathe saddle, both tool rest firmly can be fixed on the knife rest, can change tool rest quickly and easily again.

Some principles of the above the utility model heavy type cutting tools that just explains through diagrams, be not be the utility model to be confined to shown in and in described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
