Description

A kind of numerical control servo knife rest

Technical field

The utility model relates to mechanical manufacturing field, especially a kind of numerical control servo knife rest.

Background technology

China's numerically controlled lathe industry keeps fast-developing and continues to implement having obtained very great achievement under policy of stimulating the domestic demand situation in national economy, presents fast-developing and progressive good situation.As one of Core Feature parts of numerically controlled lathe, although numerically-controlled slide has been obtained compared with much progress, compare with external level, still have a certain distance, become one of bottleneck factor of restriction main frame development.

From technical development, numerical control machine tool technique at a high speed, compound, intelligence and environmental protection future development, high speed and super precision machining has become the development trend of metal cutting process technology.Core component as numerically controlled lathe---numerically-controlled slide, can guarantee that workpiece completes the manufacturing procedures such as size, endoporus, end face, circular arc, screw thread, groove automatically by clamped one time, be applicable to the industries such as lathe, household electrical appliances, automobile, gear, metallurgy.Most hydraulic tool rests that use in low-cost type CNC lathe, debug relative simple with maintenance at present.And in high-grade, digitally controlled machine tools, use high-performance servo saddle, greatly improved the working ability of numerically controlled lathe high speed performance and complex parts.

Along with the development of Digit Control Machine Tool functional part, main frame is increasing to the dependence of functional part, especially the dependence of cutter setting frame.Say to a certain extent, the development level of blade carrier component has represented the development level of main frame, and its reliability, advance are particularly outstanding.Specialized production is developing direction, and numerically-controlled slide product should be to specialized, social Collaborative future development.Digit Control Machine Tool diversity and personalized development also require numerically-controlled machine tool rest product increasing under the prerequisite of function, and extensive use new material, new technology, make product design variation.Along with the keen competition in market, the profit margin of product will reduce, and manufacturing enterprise's pattern small and comprehensive will be not suitable with the requirement of socialization production.

Existing market has been created a good development opportunity to the main function components development of Digit Control Machine Tool, should on the basis of upper level, do industrialization work well, meets as early as possible the demand of main frame development.The utility model can meet the manufacturing procedures such as size, endoporus, end face, circular arc, screw thread, groove, has greatly improved the working ability of numerical-control horizontal lathe high speed performance and complex parts.

Utility model content

Based on above problem realistic problem, analyze, the utility model discloses a kind of numerical control servo knife rest, its machine components are few, change the cutter time short, move safe and reliable, automaticity is high, can meet the manufacturing procedures such as size, endoporus, end face, circular arc, screw thread, groove, has greatly improved the working ability of numerical-control horizontal lathe high speed performance and complex parts.

Numerical control servo knife rest of the present utility model comprises tool holder body, knife rest control module, hydraulic system.Knife rest control module is connected with tool holder body by interface, obtains and in tool holder body, locks signal, back to zero signal, thermal protection for motors monitor signal and delta pulse signal.The utility model numerical control servo knife rest is after the each energising of Digit Control Machine Tool, and the back to zero that must carry out knife rest by the noncontacting switch in rear stub operates, otherwise knife rest cannot move.Hydraulic system is connected with tool holder body by oil pipe, for knife rest unclamps locking, provides pressure.

Tool holder body comprises a drive unit, and drive unit consists of servomotor, hydraulic cylinder and gear.Tool holder body also comprise cutterhead, indexing means, device for pre-positioning, unclamp and stop tight device, accurate positioning device and the checkout gear of posting a letter.The checkout gear of wherein posting a letter is the position that the collision block of fixing a feedback signal on fluted disc is determined fluted disc, and the back to zero that detect in real time cutter spacing signal by being arranged on static position switch in rear stub, realizes servo saddle operates.

Accompanying drawing explanation

Fig. 1 is the structural representation of the tool holder body of numerical control servo knife rest of the present utility model;

Wherein Reference numeral is: 1 servomotor, and 2 pulse coders, 3 gears, 4 collision blocks, 5 fluted discs, 6 unclamp the tight device of stopping, 7 static position switches, 8 cutterheads.

The specific embodiment

Numerical control servo knife rest of the present utility model, comprises tool holder body, knife rest control module, hydraulic system.Knife rest control module is connected with tool holder body by interface, for changing knife frame cutter provides power, and obtains and in tool holder body, locks signal, back to zero signal, thermal protection for motors monitor signal and delta pulse signal.Hydraulic system is connected with tool holder body by oil pipe, for knife rest unclamps locking, provides pressure.

As shown in Figure 1, tool holder body comprises drive unit, and drive unit is by servomotor 1, gear 3, and some hydraulic pressure original papers form, servomotor 1 is contained in tool holder body rear stub top.Gear 3 is arranged on the axle of servomotor 1.Fluted disc 5 and gear 3 engagements, for knife rest tool changing transposition provides power, and carry out pre-determined bit function.The rear axle head of servomotor 1 is equipped with pulse coder 2, for servomotor accurately rotates detection foundation is provided, and provides detection signal to knife rest control module.

Knife rest arrives the rotation between required station by mechanical gear 3 and fluted disc 5 drive mechanisms, and tool holder designs is six stations or eight stations, for calibration is accurate, so the number of teeth of fluted disc can not, lower than six and eight station number, generally be designed to six and eight integral multiple.

During knife rest tool changing, need to unclamp fluted disc, the tight fluted disc that needs to stop after tool changing completes, unclamps so tool holder body the inside is provided with the tight device 6 of stopping, and can complete and stops fast tight and unclamp, and the larger tight power of stopping is provided.

The checkout gear of posting a letter is the position that the collision block 4 of fixing a feedback signal on fluted disc 5 is determined fluted disc 5, and the back to zero that detect in real time cutter spacing signal by being arranged on static position switch 7 in rear stub, realizes servo saddle operates.

Cutterhead 8 use bolts are connected with 6 stations or the outer cutterhead of 8 stations with pin, and quick change cutter holder and various mechanical clamped cutting tool are housed on cutterhead outside.
