Abstract
A kind of chasing bar being applicable to numerically controlled lathe, one end of overcoat is connected with the baffle plate of annular, described baffle plate and overcoat are integrated, the inner periphery of overcoat and baffle plate enclose and pick out a tubular groove, dynamic core is placed in wherein, described dynamic core is stepped cylindrical shape structure, upper cylinder with chute, the inside of dynamic core offers the longitudinal direction of through lower cylinder and upper cylinder to through hole, screw tap is placed in longitudinal hole, described lower cylinder offers some top wire holes, and each top wire hole is crossing with longitudinal hole, and screw tap is fixed jackscrew and is placed in top wire hole and fixed by screw tap; In described baffle plate, offer pin-and-hole, insert pin in this pin-and-hole, pin slides in described chute, and pin is held out against by jackscrew; The periphery of upper cylinder is socketed with spring, and spring is placed in the inside of described overcoat.The utility model makes screw tap unloading process simple and convenient, also without the need to carrying out system call interception to loading body device after refitting screw tap, improves operating efficiency.
Description
Technical field
The utility model relates to and belongs to metal processing sectors, particularly relates to a kind of chasing bar being applicable to numerically controlled lathe.
Background technology
In prior art, the screw tap of chasing bar is changed comparatively complicated, and during general replacement screw tap, need to carry out system call interception to loading body device, adjustment process is comparatively complicated.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of chasing bar being applicable to numerically controlled lathe, changes complicated problem with the screw tap solving numerically controlled lathe chasing bar.
To achieve these goals, the technical solution adopted in the utility model is: a kind of chasing bar being applicable to numerically controlled lathe, comprise overcoat, dynamic core and screw tap, one end of overcoat is connected with the baffle plate of annular, described baffle plate and overcoat are integrated, the inner periphery of overcoat and baffle plate enclose and pick out a tubular groove, dynamic core is placed in wherein, described dynamic core is stepped cylindrical shape structure, the radius of the lower cylinder of dynamic core is greater than the radius of cylinder, upper cylinder is with chute, the inside of dynamic core offers the longitudinal hole of through lower cylinder and upper cylinder, screw tap is placed in longitudinal hole, described lower cylinder offers some top wire holes, each top wire hole is crossing with longitudinal hole, screw tap is fixed jackscrew and is placed in top wire hole and is fixed by screw tap, in described baffle plate, offer pin-and-hole, insert pin in this pin-and-hole, pin slides in described chute, and pin is held out against by jackscrew, the periphery of upper cylinder is socketed with spring, and spring is placed in the inside of described overcoat.
Beneficial effect: dynamic core of the present utility model is stepped cylindrical shape structure, screw tap is placed in longitudinal hole, screw tap is fixed jackscrew by the screw tap in top wire hole and is held out against, thus make screw tap unloading process simple and convenient, also without the need to carrying out system call interception to loading body device after refitting screw tap, improve operating efficiency.Move back in a process, the elastic force bounce-back of general spring, makes screw tap return original position, due to the bicylindrical shape structure of dynamic core, spring is directly installed in the cavity of dynamic core and overcoat formation, thus makes structure of the present utility model more compact.Pin is fixed in baffle plate by jackscrew, and pin is for controlling the maximum feeding limit of screw tap, and pin is fixed by jackscrew, can prevent screw tap and dynamic core from can rotate along with the main shaft of numerical control lathe when thread mill drilling.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model;
Fig. 2 is the sectional view of core.
Wherein: 1. overcoat, 2. screw tap, 3. go up cylinder, 4. descend cylinder, 5. spring, 6. pin, 7. jackscrew, 8. top wire hole, 9. longitudinal hole, 10. jackscrew fixed by screw tap, 11. baffle plates, 12. chutes.
Detailed description of the invention
In order to more clearly explain the technical solution of the utility model, become to further illustrate to the utility model below in conjunction with drawings and the specific embodiments.
Embodiment: as shown in Figure 1-2, a kind of chasing bar being applicable to numerically controlled lathe, comprise overcoat 1, dynamic core and screw tap 2, one end of overcoat 1 is connected with the baffle plate 11 of annular, described baffle plate 11 is integrated with overcoat 1, the inner periphery of overcoat 1 and baffle plate 11 enclose and pick out a tubular groove, dynamic core is placed in wherein, described dynamic core is stepped cylindrical shape structure, the radius of the lower cylinder 4 of dynamic core is greater than the radius of cylinder 3, upper cylinder 3 is with chute 12, the inside of dynamic core offers the longitudinal hole 9 of through lower cylinder 4 and upper cylinder 3, screw tap 2 is placed in longitudinal hole 9, described lower cylinder 4 offers some top wire holes 8, each top wire hole 8 is crossing with longitudinal hole 9, screw tap is fixed jackscrew 10 and is placed in top wire hole 8 and is fixed by screw tap 2, in described baffle plate 11, offer pin-and-hole, insert pin 6 in this pin-and-hole, pin 6 slides in described chute 12, and pin 6 is held out against by jackscrew 7, the periphery of upper cylinder 3 is socketed with spring 5, and spring 5 is placed in the inside of described overcoat 1.
Chasing bar in the present embodiment, can be used for the tapping hole processing M0.5 ~ M8, be specially adapted on the numerical control lathe without rigid tapping, in use procedure, this chasing bar is fixed on cutter platform, the main shaft of control system domination number car controlling slowly cuts screw tap 2 front end by needing the hole of tapping, after incision, machine Z-axis position stops, screw tap 2 follows the direction of rotation of main shaft to realize self-tapping, spring 5 on chasing bar controls screw tap 2 and resets after process finishing, pin 6 is in order to control the maximum feeding limit of screw tap 2, as for the degree of depth of tapping, by calculating, main shaft is positive/negative to be turned the time and controls, its control method is the conventional method of technical staff.
