Description
Technical field
The utility model relates to the crashproof knife system of a kind of lathe, belongs to machining equipment field.
Background technology
The crashproof knife system of lathe is developed specially for producing beads base disposal molding bore process.Utilize the special molding cutter of Intermediate Gray drill bit, coordinate this lathe to use, can high efficiency high-quality, low labour intensity mode under produce in batches, instead of the shaping ball of the first turning of traditional wood-turning machine, the old technique of also being holed by single carrying out in addition.This lathe can directly give in making sheet or section material is being processed, due to the linkage work of the head up and down mode of this lathe, so the axiality of beads through wires hole and outer spherical greatly improves, because traditional handicraft boring pierces from one end, therefore the length of the bit is beads diameter lengths, and lathe is the radius length of beads, affect by the grain of wood, drill bit is longer, can be difficult to ensure axiality.
Utility model content
The utility model for the deficiency that prior art exists, provides a kind of lathe crashproof knife system just.
For solving the problem, technical solution adopted in the utility model is as follows:
The crashproof knife system of a kind of lathe, comprise main body, drive sprocket and transition sprocket wheel are installed on the left of described bottom part body, described drive sprocket is positioned at the bottom of transition gear, lower tooth wheel shaft is installed on the right side of described main body, described lower tooth axle end be provided with interlock sprocket wheel and clutch assembly with by movable sprocket, described interlock sprocket wheel and clutch assembly and be provided with active finger ring and passive finger ring between movable sprocket, described lower tooth wheel shaft top is provided with torque spring.
Further, described drive sprocket is connected by ring chain with by between movable sprocket.
Further, described drive sprocket and transition sprocket wheel and link sprocket wheel and clutch assembly and all connected as one by rotating shaft by movable sprocket.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
The crashproof knife system of a kind of lathe described in the utility model, structure is simple, lower head is forced to move down mutually by drive sprocket with being driven the motion of initiatively finger ring and passive finger ring by the motion of movable sprocket, to prevent the generation of hitting cutter accident, lower tooth wheel shaft is under the effect of torque spring simultaneously, reversely rotate immediately, lower main axis sleeve is driven to return initial bit, bottom tool relative motion in employing, bottom tool has cut withdrawing immediately, fix a cutting tool and continue feeding 2-3mm, with regard to disposable, beads hole drill is led to like this, add efficiency and the quality of work, decrease the working time.
Accompanying drawing explanation
Fig. 1 is the crashproof knife system structural representation of a kind of lathe described in the utility model;
Wherein, 1-transition sprocket wheel, 2-drive sprocket, 3-by movable sprocket, 4-initiatively finger ring, 5-passive finger ring, 6-interlock sprocket wheel and clutch assembly, 7-lower tooth wheel shaft, 8-torque spring.
Detailed description of the invention
Below in conjunction with specific embodiments content of the present utility model is described.
As shown in Figure 1, for the crashproof knife system structural representation of a kind of lathe, comprise main body, drive sprocket 2 and transition sprocket wheel 1 are installed on the left of described bottom part body, described drive sprocket 2 is positioned at the bottom of transition gear, lower tooth wheel shaft 7 is installed on the right side of described main body, be provided with bottom described lower tooth wheel shaft 7 interlock sprocket wheel and clutch assembly 6 with by movable sprocket 3, described interlock sprocket wheel and clutch assembly 6 and be provided with initiatively finger ring 4 and passive finger ring 5 between movable sprocket 3, described lower tooth wheel shaft 7 top is provided with torque spring 8.
Further, described drive sprocket 2 is connected by ring chain with by between movable sprocket 3.
Further, described drive sprocket 2 and transition sprocket wheel 1 and link sprocket wheel and clutch assembly 6 and all connected as one by rotating shaft by movable sprocket 3.
Synchronous relative motion drive sprocket 2 drives synchronous relative motion by movable sprocket 3 III by ring chain, be locked on sprocket wheel by active finger ring 4, when throw-out-of clutch moment, finger initiatively on finger ring 4 just in time touches the finger on passive finger ring 5, because the transmission direction of ring chain is consistent with upper head, if the clutch caused at swaging clamp or other reasons has been thrown off but lower head does not return in particular cases, also under forcing under the effect of this mechanism, head moves downward, to prevent the generation of hitting cutter accident.
The sprocket wheel that the axle that cogs connects links chain through upper and lower two transition sprocket wheels 1, the interlock sprocket wheel driving lower head and clutch assembly 6 by transmission, because this chain is finally intersect to be installed on clutch sprocket, so drive lower tooth wheel shaft 7, axle rightabout moves with cogging, and drive lower sleeve to move upward, realize upper and lower spindle synchronous feeding, carry its tools is processed workpiece.When clutch rotates to precalculated position, clutch adjusting screw(rod) hits de-clutch ratchet, and clutch is separated rapidly, the transmission of holdback clutch and lower tooth wheel shaft 7, lower tooth wheel shaft 7, under the effect of torque spring 8, reversely rotates immediately, drives lower main axis sleeve to return initial bit.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
