Abstract
The utility model belongs to the technical field of machining, and particularly relates to a knife handle in tapered connection with a grinding head. The knife handle is composed of a handle part, a connecting part and a locking part. The handle part is provided with a clamping jaw groove connected with a knife jaw, the connecting part is located on the lower portion of the handle part, the connecting surface of the connecting part is of a tapered structure, the locking part is formed by a lower end cover and a screw, and the lower end cover is arranged on a locating shaft on the lower portion of the connecting part in a sleeved mode and is axially fixed through the screw. According to the knife handle, tapered connection is adopted, radial runout generated due to connecting gaps between the grinding head and the knife handle is eliminated, machining precision is improved, and the knife handle is suitable for installation of grinding heads made of various materials.
Description
Technical field
The utility model belongs to Machining Technology field, and particularly a kind of tapering connects the handle of a knife of bistrique.
Background technology
Conventional bistrique on Digit Control Machine Tool, its installation process be by grinding head center borehole jack on the connecting wall of handle of a knife, then by screw fixing and locking, the connecting wall of handle of a knife and the centre bore of bistrique are generally vertical cyclindrical shape, when this structure is in contact with one another, owing to be difficult to guaranteeing quality of fit, make between bistrique and handle of a knife, to be easy to produce connection gap, cause bistrique setting-up eccentricity, during work, produce circular runout.For plain wheel bistrique, can adopt the circular runout of the method elimination bistrique of grinding wheel; And for the bistrique with coating such as diamonds, because coating is thinner, cannot people be reconditioning, circular runout is difficult to eliminate.Although the durability of these coating bistriques is very high, due to circular runout problem, had a strong impact on its machining accuracy.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of handle of a knife that connects bistrique for tapering is provided, simple in structure, do not need reconditioning bistrique can eliminate the connection gap between bistrique and handle of a knife, and then eliminate the circular runout that bistrique produces due to setting-up eccentricity, improve machining accuracy.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of tapering connects the handle of a knife of bistrique, shank, connection part and tight lock part, consists of, and shank is provided with the claw groove connecting with cutter pawl; Point of attachment is in the below of shank, and its conjunction plane is pyramidal structure; Tight lock part is comprised of bottom end cover and screw, and bottom end cover is placed on the locating shaft of connection part below, and fixes by screw axial.
Above-mentioned a kind of tapering connects the handle of a knife of bistrique, below described shank claw groove, is evenly provided with some radial screw bore.
The handle of a knife that above-mentioned a kind of tapering connects bistrique is when clamping bistrique, first back out the screw of tight lock part, bottom end cover is pulled down from locating shaft, then the centre bore tapering bistrique consistent with conjunction plane tapering is placed on to connection part, again bottom end cover is reinstalled on locating shaft, and make bottom end cover hold out against bistrique by screw.
Compared with prior art, the beneficial effects of the utility model are: the utility model grinding head center hole is set to tapering with handle of a knife conjunction plane and connects, between contact-making surface, can not produce connection gap, can guarantee well axiality when bistrique and handle of a knife are installed, can eliminate the circular runout that bistrique causes due to setting-up eccentricity, improve machining accuracy.In addition, on the periphery of handle of a knife, be also provided with some radial screw bore, the imbalance problem while being conducive to regulate handle of a knife to install, and then eliminate the vibration causing due to handle of a knife.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Structural representation when Fig. 2 is the utility model connection bistrique.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail.
Shown in Fig. 1 and Fig. 2, a kind of tapering of the present utility model connects the handle of a knife of bistrique, by shank 10, connection part 20 and tight lock part 30, formed, on shank 10, be provided with the claw groove 11 connecting with cutter pawl, on periphery below claw groove 11, be provided with radial hole 12, radial hole 12 is uniformly distributed around axis; Connection part 20 is positioned at the below of shank 10, and its conjunction plane is pyramidal structure; Tight lock part 30 is comprised of bottom end cover 31 and screw 32, and bottom end cover 31 is placed on the locating shaft 33 of connection part 20 belows, and fixing by screw 32.
During clamping bistrique 40, first back out the screw 32 of tight lock part 30, bottom end cover 31 is pulled down from locating shaft 33, then the centre bore tapering bistrique 40 consistent with conjunction plane tapering is placed on connection part 20, again bottom end cover 31 is reinstalled on locating shaft 33, and making bottom end cover 31 hold out against bistrique 40 by screw 32, bistrique 40 is fixed on the connection part 20 of handle of a knife, and very close to each other between the two.
The utility model, by adopting tapering to connect, has been eliminated the circular runout producing due to connection gap between bistrique and handle of a knife, has improved machining accuracy, is applicable to the installation of various material bistriques.
Claims (2)
1. tapering connects a handle of a knife for bistrique, shank, connection part and tight lock part, consists of, and shank is provided with the claw groove connecting with cutter pawl; Point of attachment, in the below of shank, is characterized in that: the conjunction plane of connection part is taper; Tight lock part is comprised of bottom end cover and screw, and bottom end cover is placed on the locating shaft of connection part below, and fixes by screw axial.
2. a kind of tapering according to claim 1 connects the handle of a knife of bistrique, below described shank claw groove, is evenly provided with some radial screw bore.
