Description
Technical field
The utility model relates to a kind of overall servomotor holder structure.
Background technology
At present, various model vertical machining centre completes X-axis side-to-side movement, and (namely workbench moves left and right, to complete the cutting movement of cutter) the practice be, X-axis servomotor is fixed on servo motor seat 2(as shown in Figure 2) on, this servo motor seat 2 comprises motor mounting flange 202, as shown in Figure 3, servo motor seat 2 screw 201 is fixed on saddle 1(as shown in Figure 1) on, servomotor 3 to be connected with ball screw 5 through shaft coupling 4 and to drive ball screw 5 to rotate, the rotation of ball screw 5 drives the nut seat (not shown) side-to-side movement of being fixed on workbench through nut (not shown), thus drive workbench (not shown) to move left and right, realize the quick movement of cutter and cut feed motion.Traditional way is after servo motor seat 2 being made separately, then is fixed on saddle 1 with screw 201 by servomotor holder 2, i.e. split type servo motor seat.
Facts have proved, this split type servo motor seat is when lathe carries out heavy cut and X-axis high speed feed or commutates at a high speed, because of the unexpected increase of impact load, servo motor seat can be made to produce slight deformation or displacement, this is mainly because servo motor seat and saddle are split type, although motor cabinet is screwed on saddle, but when being subject to suddenly the impact of external force, stressed weak link is remained at the fixed combinating surface place of servo motor seat and saddle, slight distortion and displacement can be produced, simultaneously because servo motor seat and saddle are splits, the fixing contact surface of servo motor seat and saddle is limited, this also affects bulk strength and the rigidity of servo motor seat, micro-strain can be produced when being subject to larger External Force Acting, can vibrate when being subject to greater impact formula External Force Acting.The phenomenons such as these displacements of servo motor seat or distortion or vibration directly causes the distortion of X-axis screw mandrel, bearing stress increases, the decentraction stress increase of shaft coupling, final result is reflected in X-axis mismachining tolerance and increases, Dimension Measurement is unstable, especially adds impact in man-hour at heavy cut comparatively outstanding.
Utility model content
The utility model provides a kind of overall servomotor holder structure, eliminate slight deformation that the servo motor seat that causes because of servo motor seat and saddle split-type design at present produces when heavy cut and high-speed motion and high speed commutate, displacement and oscillation phenomenon, make the X-axis servo motor seat after improvement effectively can improve himself intensity and rigidity, make the dimensional accuracy of processing work be further enhanced and stablize, guarantee the crudy of precision component.
In order to achieve the above object, the utility model provides a kind of overall servomotor holder structure, and this overall servomotor holder structure comprises servo motor seat and the saddle of integral casting forming.
Motor mounting flange and the saddle integrally casting of described servo motor seat are shaping.
Described overall servomotor holder structure also comprises the reinforcement being arranged on servo motor seat and saddle junction.
The utility model eliminates slight deformation that the servo motor seat that causes because of servo motor seat and saddle split-type design at present produces when heavy cut and high-speed motion and high speed commutate, displacement and oscillation phenomenon, make the X-axis servo motor seat after improvement effectively can improve himself intensity and rigidity, make the dimensional accuracy of processing work be further enhanced and stablize, guarantee the crudy of precision component.

Detailed description of the invention
Following according to Fig. 4 ~ Fig. 6, illustrate preferred embodiment of the present utility model.
Through the analysis to original servo motor seat and assembling thereof, find that its main cause impacted machine finish is partial installation because of servo motor seat and saddle, although servo motor seat is screwed on saddle, but its intensity and rigidity deficiency, under the strong impact force effect produced when heavy cut and high-speed motion commutation, still have micro-deformation and displacement.
As shown in Fig. 4 ~ Fig. 5, in order to eliminate micro-deformation that servo motor seat produces under strong impact force effect, displacement and vibration, the utility model provides a kind of overall servomotor holder structure, and this overall servomotor holder structure 11 comprises servo motor seat 1101 and the saddle 1102 of integral casting forming.
The motor mounting flange 1104 of servo motor seat 1101 is shaping with saddle 1102 integrally casting.
Described overall servomotor holder structure 11 also comprises the reinforcement 1103 being arranged on servo motor seat 1101 and saddle 1102 junction, strengthens the strength and stiffness of motor mounting flange.
As shown in Figure 6, servomotor 33 to be connected with ball screw 55 through shaft coupling 44 and to drive ball screw 55 to rotate, the rotation of ball screw 55 drives nut seat 77 side-to-side movement of being fixed on workbench through nut 66, thus drive workbench 88 to move left and right, realize the quick movement of cutter and cut feed motion.
Structural advantages of the present utility model is: one is thoroughly eliminate the micro-displacement and vibration that produce because screw connection portion position is subject to strong External Force Acting; Two is because integrated casting structure increase reinforcement, makes the intensity of servomotor mounting flange and bearing mounting base and rigidity obtain larger raising; Three is that the intensity of saddle transmission portion and rigidity are also improved, and the overall drive mechanism of saddle improves because motor mounting flange and bearing mounting base and saddle are connected as a single entity and add reinforcement.
After servo motor seat after the improvement that the utility model provides uses on lathe, compared with the lathe before improving, bulk strength and the rigidity of saddle transmission portion improve further, X-axis high-speed motion and commutation time and heavy cut add man-hour, the distortion of servo motor seat, displacement and oscillation phenomenon are eliminated substantially, transmission rigidity and the stability of X-axis entirety significantly improve, positioning precision and the repetitive positioning accuracy of lathe are improved, the dimensional accuracy of processing work has had obvious improvement, reaches the object that the utility model improves servo motor seat.
Although content of the present utility model has done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to restriction of the present utility model.After those skilled in the art have read foregoing, for multiple amendment of the present utility model and substitute will be all apparent.Therefore, protection domain of the present utility model should be limited to the appended claims.
