Detailed description of the invention
As shown in Figure 1, numerically controlled lathe automatic feed mechanism, described numerically controlled lathe is provided with hollow spindle 9, comprise stock shelf 4, pusher cylinder 2, charging ram 3, by barrel 16, charge channel 5 and upper barrel 6.
Stock shelf 4 is arranged on the afterbody of numerical control lathe main axle box, keeps fixing to allow stock shelf 4 and Digit Control Machine Tool relative position, can feeding in continuous material to ensure, stock shelf can be fixedly connected with Digit Control Machine Tool or be fixed on the ground by stock shelf 4.
Pusher cylinder 2 is arranged on stock shelf 4, connects charging ram 3 at the clutch end of pusher cylinder 2, and the diameter of charging ram 3 is larger than the diameter of pusher cylinder 2 extension bar, to meet the conveying without diameter segment material.
Charging ram 3 is arranged on by barrel 16, and the side by barrel 16 is connected with charge channel 5.
Charge channel 5 designs according to the needs of different production lot, can be designed to fixed dimension, also can be designed to adjustable.Particularly, the batch as fruit product is large, and specification is single, and charge channel 5 can make fixed dimension, and the structure of the charge channel 5 of setting is like this simple, expense is low, use is reliable; Few for product quantity, specification is changeable, then can be designed to adjustable by charge channel 5, to meet the material loading demand of different size, size section material.
Charge channel 5 can be obliquely installed with vertical direction, with the section of convenience material can under the effect of deadweight automatic transport to by barrel 16.
Upper barrel 6 is arranged in the closing sleeve 8 in hollow spindle 9.For leading to the conveying of section material, ensure that section material is can not run-off the straight in course of conveying.
Upper barrel 6 can adopt engineering plastics to be made, and its external diameter comparable closing sleeve 8 is bigger, during assembling, firmly upper barrel 6 is compressed into closing sleeve 8.
Can according to the internal diameter of the upper barrel 6 of diameter specifications design of institute's epimere material, upper barrel 6 is detachably arranged in closing sleeve 8, can expect that the difference of diameter is changed according to section.
Charging ram 3, coincide by the center line of barrel 16 and upper barrel 6 setting, and upper barrel 6 coincides with the center line of hollow spindle 9 and arranges.
Pusher cylinder 2 is two rod cylinder preferably, and one end of two rod is clutch end, and for being connected with charging ram 3, the other end is connected with cylinder stroke adjusting sleeve 1.Cylinder stroke adjusting sleeve 1 is set on extension bar, and carries out axial location with nut to it.According to the difference of the length of institute's epimere material, change the position of cylinder stroke adjusting sleeve 1 on extension bar, to ensure that the pusher stroke of pusher cylinder 2 is enough to section material to be pushed to preposition.
In order to improve the positioning precision (mainly referring to axial location precision here) of workpiece (namely refer on section material) herein, the utility model is also provided with a locating piece 15 on the cutterhead of numerically controlled lathe, can ensure that the axial location precision of workpiece reaches the repetitive positioning accuracy same level of numerically controlled lathe, compared with material loading manually, the precision and stability of location is greatly improved, and can meet the processing request of high-precision workpiece completely.
Fig. 2 illustrates the utility model a kind of Pneumatic control circuit connection layout in a specific embodiment.
In this embodiment, numerically controlled lathe is provided with oild chuck rotary oil cylinder 7 originally, closing sleeve 8 is fixedly connected with oild chuck rotary oil cylinder 7, by the power transmission of oild chuck rotary oil cylinder 7 to oild chuck 11 to realize the clamping of workpiece and (herein for prior art, therefore not the describing in detail) of unclamping.
Upper barrel 6 passes from the hollow piston of oild chuck rotary oil cylinder 7, is arranged in closing sleeve 8.
Like this, when hollow spindle 9 rotates, while namely drive workpiece (herein section material) rotates, in drive, the section material to be processed of barrel 6 and inside rotates together, under the constraint of upper barrel 6, and section material marshalling and can not be at random.
This Pneumatic control circuit comprises for providing the source of the gas 20 of power and the three position four-way directional control valve 18 for changing gas flow in pusher cylinder 2 for pusher cylinder 2.In order to regulate the advance and retreat speed of piston in pusher cylinder 2, pusher cylinder 2 air inlet and go out in air circuit to be separately installed with a throttle grverning valve 17.In addition in order to ensure that the outlet pressure of source of the gas 20 meets the needs of different specification section material, go out in air circuit to be also provided with a pressure-reducing valve 19 at source of the gas 20, (need larger propelling movement power when section material size is large, weight is large, when section material size is little, weight hour then needs less propelling movement power).
Pneumatic control circuit in present embodiment, be connected the first pressure switch and the second pressure switch in the oil-feed loop of oild chuck rotary oil cylinder 7 respectively with going out on oil return line, the control output end of two pressure switches respectively with three position four-way directional control valve 18 control connection.
Present embodiment specific works process is as follows:
As shown in Figure 2, when oild chuck rotary oil cylinder 7 back cavity is (with piston rod external part for ante-chamber, end opposite is back cavity, from figure, the side be connected with hydraulic fluid port D is ante-chamber, the side be connected with hydraulic fluid port C is back cavity) oil-feed time, the soft pawl 13 be arranged on oild chuck 11 by soft pawl transition block 12 unclamps workpiece, after oild chuck rotary oil cylinder 7, cavity pressure raises, the first pressure switch 21 that the fluid pressure line that is connected with back cavity is installed is connected, the corresponding electromagnet energising of the three position four-way directional control valve on pusher Pneumatic control circuit, make the back cavity of pusher cylinder 2 (in Fig. 2, the side be communicated with hydraulic fluid port B is ante-chamber, the side be communicated with hydraulic fluid port A is back cavity) air inlet promotes cylinder piston and to move ahead pusher, pusher is to the front end of hollow spindle 9, when putting in place, the circular cutting disk 14 of numerically controlled lathe turns to the working position of locating piece 15, and the position location needed for the circumference section of moving to material, complete the accurate location to workpiece, then, the oil-feed of oild chuck rotary oil cylinder ante-chamber 7, piston is return, simultaneously, the back cavity of oild chuck rotary oil cylinder 7 loses pressure, first pressure switch 21 disconnects, the corresponding electromagnet dead electricity of three position four-way directional control valve, when the piston of oild chuck rotary oil cylinder 7 moves forward to extreme position, soft pawl 13 clamping work pieces on oild chuck 11, now, before oild chuck rotary oil cylinder 7, cavity pressure raises, second pressure switch 22 is connected, corresponding electromagnet energising in three position four-way directional control valve, the piston driving charging ram 3 of pusher cylinder 2 is retracted into original position, charging ram 3 return the length having abdicated a section material, section material in charge channel 5 under gravity, roll along inclined-plane, make a section material just in time drop on by barrel 16, ready for circulating next time.
Adopt the utility model, original to corresponding pneumatic circuit and numerically controlled lathe hydraulic circuit can be combined, when not changing former numerically controlled lathe electrical equipment cyclic program, the do action of material loading is rubbed in the whole systemic circulation of numerically controlled lathe cleverly, greatly increase working (machining) efficiency and machining accuracy that numerically controlled lathe section material adds man-hour.
