Abstract
The utility model relates to a direct-coupling drive apparatus of a digital control rotary tower puncher, comprising a connecting rod and a positioning slider. The utility model is characterized in that a crankshaft is arranged on a puncher body corresponding to the upper part of the positioning slider; a servo motor is arranged at the end part of the crankshaft; the connecting rod arranged on the crankshaft journal is connected with the positioning slider via a movable joint. Compared with the mechanical drive apparatus and the hydraulic drive apparatus, the utility model has the advantages of simple and reasonable structure, low cost, convenient installation and maintenance and reliability.
Description
Technical field
The utility model relates to a kind of transmission device of NC turret punch machine, and particularly a kind of Direct Connected Main Drive of Numerical Control Turrent Punch Press belongs to the punching press field.
Background technology
The existing main drive of numerical control press mainly contains two kinds of mechanical main transmission and hydraulic pressure main transmissions.For mechanical main drive, its structure mainly is made up of attacking head, slide block, connecting rod, bent axle, flywheel, clutch, controller and motor etc., described attacking head is assemblied in the slide block lower end, the installing hole that attacking head passes capstan head is contained in the top of patrix, upper end of slide block is connected the connecting rod lower end by pin, and small end is contained on the bent axle, and bent axle passes frame and is connected with flywheel through clutch, flywheel shaft is connected with motor through belt or chain, and clutch is controlled by the controller.Because attacking head is by Motor Drive by connecting rod, bent axle and clutch, so obviously there are following several point defects: 1, because attacking head is interrupter duty, and motor and flywheel are continuous operations, so, the control action of clutch and brake is frequent, its maximum punching frequency can reach per minute 300 times, makes the fault rate height of control assembly; 2, the motor because the use common electric machine is decided, thereby its punching frequency is changeless, has significant limitation; 3, be by the decision of the offset of bent axle, so its punching stroke is also non-adjustable because of its punching stroke; 4, because motor speed is constant, and when lathe did not carry out punching press, motor drove flywheel work as usual, energy loss is big; 5, because parts such as flywheel, clutch and controller are installed, make the complex structure of main drive, install, adjust and the maintenance inconvenience.
For the hydraulic pressure main drive, its structure is mainly by attacking head, slide block, slider guide seat and hydraulic pressure main transmission part are formed, drive slide block by the hydraulic pressure main transmission part and slide up and down the attacking head work that makes along the slider guide seat, its punching frequency and punching stroke all can be regulated by the hydraulic pressure main transmission part, has the wide advantage of the scope of application, but because of the hydraulic pressure main transmission part is to carry out work by hydraulic oil, need with hydraulic systems such as hydraulic pump and fluid pressure lines supporting with it, and the fluid pressure line of hydraulic system and Hydraulic Elements are more, be easy to generate leakage phenomenon, cause environmental pollution, increase maintenance workload.Because of the at present main dependence on import of hydraulic pressure main transmission part, cost is more much higher than mechanical main transmission NC turret punch machine, is unfavorable for generally using at home again.
Summary of the invention
The purpose of this utility model is: at the problem of existence in the transmission device use of present NC turret punch machine, provide a kind of direct-connected main drive of NC turret punch machine.
The purpose of this utility model is achieved in that a kind of Direct Connected Main Drive of Numerical Control Turrent Punch Press, comprise connecting rod, positioning sliding block, it is characterized in that: the punch press body corresponding to positioning sliding block top is provided with bent axle, crankshaft end is provided with servomotor, and the connecting rod that is installed on the crankshaft journal is connected with positioning sliding block by movable joint.
Advantage of the present utility model is: owing to using servomotor to cancel clutch and parts such as controller and flywheel, its structure is than mechanical type main drive advantages of simple more; Owing to use servomotor, realized punching press frequency that the fluid pressure type main drive is had and the advantage that punching stroke all can be regulated arbitrarily and the punching press frequency is high, its cost is cheaper, and installation and maintenance are convenient; In actual use, reliability of the present utility model not only is higher than the NC turret punch machine that uses the mechanical type main drive, also is higher than the NC turret punch machine of fluid pressure type main drive.
Description of drawings
Fig. 1 is a kind of example structure schematic diagram of the present utility model.
Among the figure: 1, connecting rod, 2, positioning sliding block, 3, bent axle, 4, servomotor, 5, movable joint, 6, bearing, 7, axle journal, 8, bearing shell, 9, the punch press body.
The specific embodiment
The nonrestrictive structural representation of showing a kind of specific embodiment of the present utility model of accompanying drawing, the utility model will be further described below in conjunction with accompanying drawing.
As seen from Figure 1, the utility model is provided with bent axle 3 on the punch press body 9 corresponding to positioning sliding block 2 tops, and servomotor 4 is equipped with in the one or both ends of bent axle 3, and the connecting rod 1 that is installed on the crankshaft journal 7 is connected with positioning sliding block 2 by movable joint 5; During concrete enforcement, described bent axle 3 is installed in by two bearings 6 on the punch press body 9 on positioning sliding block 2 tops, and connecting rod 1 is installed on the axle journal 7 of bent axle 3 by bearing shell 8; In the present embodiment, servomotor 4 all is equipped with at the two ends of bent axle 3.
In the use, upper trimming die is installed in the below of positioning sliding block 2, punching stroke of the present utility model is realized by the rotational angle that changes servomotor 4, rotational angle is big, punching stroke is just long, otherwise then short, the length of punching stroke can be adjusted axle journal 7 is rotated to the actual range of bent axle 3 minimum points by the peak of bent axle 3 in; Punching press frequency of the present utility model is consistent with the round rotational frequency of servomotor 4, when changing servomotor 4 rotational frequencies, has also just changed the punching press frequency.
Claims (4)
