Description
Technical field
The utility model relates to mechanical equipment technical field, particularly relates to a kind of high-efficiency and precision numerically controlled lathe.
Background technology
High-efficiency and precision numerically controlled lathe is a kind of high accuracy, high efficiency, automated machine tool of being equipped with multistation cutter tower or power cutter tower, there is process industrial art performance widely, can processing linear cylinder, oblique line cylinder, the complex part such as circular arc and various screw thread, groove, worm screw, there is linear interpolation, the various compensate function of circular interpolation, and in the batch production of complex parts, played good economic effect.High-efficiency and precision numerically controlled lathe relies on cutter at high speeds running to play Precision Machining effect, can produce much noise in the process, cause work condition environment extreme, affect staff physically and mentally healthy.
Utility model content
Technical problem to be solved in the utility model is to overcome the problems referred to above, and the high-efficiency and precision numerically controlled lathe providing a kind of running noises little.
The technical solution of the utility model is:
High-efficiency and precision numerically controlled lathe described in the utility model, comprise protective cover and be placed in the bed body in protective cover, described protective cover comprises multiple Wall board engaged successively, it is characterized in that: described each Wall board is convexly equipped with a support frame arranged around its inwall outer rim, described support frame is fitted with a sound deadening sheet be parallel to each other with the Wall board at its place, described Wall board, support frame and sound deadening sheet enclose formation noise reduction cavity thus; Described sound deadening sheet is also densely covered with several sound absorption wedge, and described each sound absorption wedge is hollow form and its outer wall is evenly equipped with several sound-absorption hole.
In said structure, the utility model is for traditional machine tool running noise this defect large, double form in conjunction with thin plate resonance noise-reducing structure and sound absorption wedge structure carries out structure improvement to each Wall board of protective cover, can efficient absorption, all kinds of running noises that produce when weakening the rotary-cut of bed height speed, carry out effective noise blocking-up from control route of transmission angle.
Further, in high-efficiency and precision numerically controlled lathe described in the utility model, described sound absorption wedge is square cone, and each side is isosceles acute triangle and makes the noise reduction attenuating on each completely the same.
Further, in high-efficiency and precision numerically controlled lathe described in the utility model, one of them described Wall board offers the installing port observing door for setting-in, the sound deadening sheet corresponding to it offers No. two installing ports corresponding with an installing port.
Further, in high-efficiency and precision numerically controlled lathe described in the utility model, described sound deadening sheet adopts corrosion resistant plate, has that toughness is high, mechanical strength is large, high temperature resistant, not yielding, the multiple advantage such as the corrosion of resistance to cooling.
The beneficial effects of the utility model are:
1, the utility model is on the basis of traditional machine tool volume not increasing equivalent efficacy, forms noise-reducing structure machine tool running noise is significantly decayed when flowing through Wall board absorptions at protective cover inwall, effectively the low noise performance of raising lathe.
2, in noise-reducing structure described in the utility model, thin plate is resonated noise-reducing structure, sound absorption wedge structural integrity combine, have the advantage of above-mentioned two kinds of structures concurrently, improve noise reduction efficacy further.

Detailed description of the invention
Now by reference to the accompanying drawings the utility model is further described:
With reference to shown in Fig. 1, Fig. 2, a kind of high-efficiency and precision numerically controlled lathe described in the present embodiment, the bed body 1 comprising protective cover 2 and be placed in protective cover, described protective cover 2 comprises multiple Wall board 3 engaged successively.Shown in composition graphs 2 and Fig. 3, described each Wall board 3 is convexly equipped with a support frame 4 arranged around its inwall outer rim, described support frame 4 is fitted with a sound deadening sheet 5 be parallel to each other with the Wall board 3 at its place, described Wall board 3, support frame 4 enclose formation noise reduction cavity with sound deadening sheet 5 thus.More specifically, described sound deadening sheet 5 adopts the corrosion resistant plate corrosion-resistant, not yielding, mechanical strength is large.Described sound deadening sheet 5 is also densely covered with several sound absorption wedge 6, described each sound absorption wedge 6 is hollow form and its outer wall is evenly equipped with several sound-absorption hole 6-1(with reference to Fig. 5), wherein said sound absorption wedge 6 is square cone, and namely each side is all in isosceles triangle.With reference to Fig. 1 and Fig. 4, one of them described Wall board 3 also offers the installing port 7 observing door for setting-in, sound deadening sheet 5 corresponding to it offers No. two installing ports 8 corresponding with an installing port 7, and shape, the size of a described installing port 7 and No. two installing ports 8 are all completely the same.
The present embodiment is intended to solve how to improve this technical problem of Digit Control Machine Tool noise-reduction, thus protection machine operator's is healthy, improves operating environment further.When lathe is in high speed rotary-cut state, consequent a large amount of mechanical noise is significantly cut down through structures such as sound absorption wedge 6, sound deadening sheet 5, noise reduction cavitys successively in outside diffusion process.Wherein, sound absorption wedge 6 is based on transition principle gradually, and when noise sound wave is from most advanced and sophisticated incidence, because the end area of wedge is little, the acoustic impedance of wedge end face will from progressively increasing close to air characteristics impedance thus reaching the object of absorption of noise; Thereafter sound wave effect is in sound deadening sheet 5 surface, causes the flexural vibrations of sound deadening sheet 5 under the alternation effect of acoustic pressure.Due to the friction between sound deadening sheet 5 and support frame 4 and sound deadening sheet 5 inside cause in frictional dissipation, the kinetic transformation of vibration is made to be that heat energy makes acoustic energy be decayed, and the sound-absorption hole 6-1 of its surface distributed can weaken sound wave reflection greatly, improve its sound-absorbing efficiency.
