Abstract
The invention provides a spring assembly for broaching during machining of a central main shaft. The spring assembly comprises a pop rivet and a spring sleeve, wherein a carrier rod is arranged in the spring sleeve; the carrier rod is connected with a pull rod of a main shaft through an inner thread; open notches are formed on the spring sleeve; a conical step is formed at the front end of the carrier rod; three open notches are provided. According to the spring assembly, an integral spring sleeve is adopted, and a carrier rod cone is adopted, so that radial deformation is generated, the structure becomes simple and easy to use, and high stability is kept.
Description
Technical field
The invention belongs to mechanical field, relate in particular to a kind of machining center main spindle broach main assemblage of spring.
Background technology
At present general machining center mainshaft broaching tool gear adopts four tension pieces to link together by spring.This kind of structure easily makes broaching tool thrashing when spring failure, causes pulling claw not open, the blind rivet damage.
Summary of the invention
The invention provides a kind of machining center main spindle broach main assemblage of spring, solved the shortcoming that the broaching tool spring in the background technology easily lost efficacy.
Technical scheme of the present invention is achieved in that machining center main spindle broach main assemblage of spring, comprise blind rivet, spring housing, be provided with push rod in spring housing, push rod is connected with the pull bar of main shaft by internal thread, spring housing is provided with open slot, and the push rod front end is provided with type conical bench;
The quantity of described open slot is 3.
The invention has the beneficial effects as follows: the present invention has adopted the mode of Monolithic spring cover, utilizes the effect of push rod cone, thereby produces radial deformation, structure is become and be simple and easy to use, has kept good stability.
The accompanying drawing explanation
Fig. 1 is generalized section of the present invention;
The top view that Fig. 2 is spring housing of the present invention.
Fig. 3 is overall structure schematic diagram of the present invention.
Accompanying drawing explanation: 1, blind rivet, 2, spring housing, 3, push rod, 4, open slot, 5, type conical bench.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described: machining center main spindle broach main assemblage of spring, comprise spring housing 2 and push rod 3, push rod 3 is contained in spring housing 2, on push rod 3, there is internal thread to be connected with the pull bar of main shaft, be processed with 3 open slots 4 that can make spring housing 2 open on spring housing 2, push rod 3 front ends are processed with type conical bench 5.When push rod 3 is moved forward by the effect of external force, rely on type conical bench 5 that spring housing 2 is opened, blind rivet 1 enters in spring housing 2, and when push rod 3 is moved by external force backward, the type conical bench 5 on it does not play a supportive role, and spring housing 2 relies on its spring that blind rivet 1 is held tightly.
The present invention has adopted the mode of Monolithic spring cover, utilizes the effect of push rod cone, thereby produces radial deformation, structure is become and be simple and easy to use, has kept good stability.
