Be equipped with on the leading flank direction of height central line of stand 500 and be the stand recess 501 of indent, on the bearing frame 321 that moves screw 420 both ends and move motor 430 to indulge all through the bolt fastening in stand recess 501 inner wall, this stand recess 501's design make full use of stand 500 self space, and the maximize eliminates the whole fore-and-aft direction extension space that occupies of the vertical feed mechanism 400 of die-knife, and then cooperates base 100 wholly to reduce its manufacturing dimension, reduction in production cost. A suspension table 104 is arranged behind the base 100 and above the discharge channel 102, and the upright 500 is fixedly connected with the suspension table 104 through bolts.

It is worth to be noted that, the front side surface of the large supporting plate 410 and two sides of the supporting plate groove 412 are vertically provided with transverse rail grooves 413, the back surface of the small supporting plate 310 is vertically and symmetrically fixed with transverse sliding rails 311, a transverse sliding rail 340 inserted with the transverse sliding rails 311 is fixed in the transverse rail grooves 413 through bolts, the middle part of the cross section of the transverse sliding rail 340 is an inward concave arc surface, the outer side surface of the transverse sliding rail 311 is provided with a through groove matched with the transverse sliding rail 340 in size, so as to form a limiting mechanism, and ensure that the small supporting plate 310 slides stably in front of the large supporting plate 410. Vertical rail grooves 502 are vertically formed in the front side face of the upright 500 and two sides of the upright groove 501, longitudinal sliding rails 411 are transversely and symmetrically fixed on the back face of the large supporting plate 410, longitudinal sliding rails 440 which are connected with the longitudinal sliding rails 411 in an inserting mode are fixed in the vertical rail grooves 502 through bolts, the middle of the cross section of each longitudinal sliding rail 440 is an inwards concave arc face, through grooves matched with the longitudinal sliding rails 440 in size are formed in the outer side faces of the longitudinal sliding rails 411, a limiting mechanism is formed, and the large supporting plate 410 is guaranteed to slide stably in front of the upright 500. The transverse slide rail 311, the transverse slide rail 340, the longitudinal slide rail 411 and the longitudinal slide rail 440 are all manufactured by C3 grade precision linear guide rails of silver-coated (HIWIN) or silver-coated titanium (PMI) company in Taiwan, the structure is compact, the motion is stable, the precision is high, the rigidity is high, a high-stability mechanical guide system is provided, and the highest moving speed can reach 30m/min by the cooperation of double-nut ball screws, so that the requirement on the processing speed is met, and the processing efficiency is favorably improved.

In this embodiment, the top of stand 500 and the externally mounted that is located to indulge and moves motor 430 have nitrogen gas counter weight balanced system 600, compare general merry go round machine and adopt mechanical counter weight or not dispose balancing unit, it includes the nitrogen cylinder, control system and balance cylinder, control system is connected with balance cylinder through the trachea, mainly utilize the energy storage ware principle, the balanced jar complex of control is indulged and is moved motor 430 steady operation, in order to reach high speed, high accuracy processing, and can prolong screw rod and motor life, its cost is lower, stability is better, it is more convenient to maintain and inspect.

When the disc parts are machined on a small vertical lathe, the disc parts are firstly installed on a main shaft working table and fixed, cutters on a cutter disc of a servo cutter tower 200 are determined according to a machining mode, a servo motor in a power box 210 is started to drive the cutter disc to rotate so as to transfer the required cutters to one side of the disc parts, then a transverse moving motor 330 and a longitudinal moving motor 430 are alternately started until the cutters lean against the side face of the machining position of the disc parts, namely, a cutter setting procedure is completed, a machining program in a machine tool computer is started, a main shaft motor 120, the transverse moving motor 330 and the longitudinal moving motor 430 are automatically and cooperatively started, so that the disc parts are cut into the required product shape according to the program setting while rotating, scraps machined by workpieces slide into a discharging channel 102 along a discharging table 101 and are accumulated, and workers regularly draw out and clean the disc parts, the small vertical lathe reduces the design weight of each casting, the range of machine tool machining parts is reduced, the whole structure is more compact, the use area of the occupied area of a factory building is reduced, and the production cost is reduced.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
