Description

A kind of bearing inner sleeve fast fixture

【Technical field】

It the utility model is related to a kind of clamping device, and in particular to a kind of bearing inner sleeve fast fixture, belong to frock Clamp art.

【Background technology】

Bearing inner sleeve usually requires that workpiece is clamped and locked using fixture before processing, with ensure machining accuracy and Safety of workers.However, the frock clamp of prior art often uses thread locking structure, it locks cumbersome, and easily makes Into loosening, work safety accident can be led to when serious.

Therefore, in order to solve the above technical problems, a kind of bearing inner sleeve fast fixture it is necessory to provide innovation, with Overcome the defect of the prior art.

【Utility model content】

To solve the above problems, the purpose of this utility model is to provide a kind of simple in construction, easy to use and locking jail Solid bearing inner sleeve fast fixture.

To achieve the above object, the technical scheme that the utility model is taken is：A kind of bearing inner sleeve fast fixture, its Including chuck, fixture set, pull bar, cam bit, rotating shaft and handle；Wherein, the chuck is located in fixture set, and can be along fixture The axis movement of set；Described chuck one end clamps a workpiece, and the other end connects with the pull bar；The cam bit is located at fixture set Outside, it which is provided with a circular hole；The rotating shaft passes through circular hole and pull bar, pull bar and cam bit is articulated；The cam bit has One locking while and one unclamp while, the center of circle of circular hole to locking while vertical range be more than the center of circle of circular hole to vertical during release Distance；The locking side can be connected to fixture and put, and chuck is locked；The handle is bolted in cam bit.

Bearing inner sleeve fast fixture of the present utility model is further arranged to：The chuck is set close to one end of workpiece There is an expanded head part, the fixture set can extrude the expanded head part, chuck is clamped workpiece.

Bearing inner sleeve fast fixture of the present utility model is further arranged to：It is described locking while unclamp while between lead to Cross one section of circular sliding slopes.

Compared with prior art, the utility model has the advantages that：Bearing inner sleeve quick clip of the present utility model Tight apparatus structure is simple, easy to use, and it uses cam bit to make locking firm, be not easy to fail, security is significantly come locking chuck Improve.

【Brief description of the drawings】

Fig. 1 is the stereogram of bearing inner sleeve fast fixture of the present utility model.

Fig. 2 is the profile of bearing inner sleeve fast fixture of the present utility model.

Fig. 3 is the locking state figure of bearing inner sleeve fast fixture of the present utility model.

Fig. 4 is the structural representation of the cam bit in Fig. 1.

【Embodiment】

Referring to shown in Figure of description 1 to accompanying drawing 4, the utility model is a kind of bearing inner sleeve fast fixture, its It is made up of several parts such as chuck 1, fixture set 2, pull bar 3, cam bit 4, rotating shaft 5 and handles 6.

Wherein, the chuck 1 is located in fixture set 2, and can be moved along the axis of fixture set 2.Described one end of chuck 1 clamps One workpiece 10, the other end and the pull bar 3 connect.Further, the chuck 1 is provided with an expanded head part close to one end of workpiece 10 11, the fixture set 2 can extrude the expanded head part 11, chuck 1 is clamped workpiece 10.

The cam bit 4 is located at outside fixture set 2, which is provided with a circular hole 41.The rotating shaft 5 passes through circular hole 41 and pull bar 3, Pull bar 3 and cam bit 4 is set to be articulated.

The cam bit 4 has a locking when 42 and one are unclamped 43, and the center of circle of circular hole 41 is to locking the vertical of side 42 Distance B is more than the center of circle of circular hole 41 to the vertical range A on release side 43.And the locking side 42 can be connected on fixture set 2, and Chuck 1 is locked.The locking while 42 and 43 when unclamping between connected by one section of circular arc 44, consequently facilitating cam bit 4 rotates.

The handle 6 is bolted in cam bit 4, and it can rotatable cam blocks 4.

The operation principle of bearing inner sleeve fast fixture of the present utility model is as follows：When clamping workpiece 10, pass through hand Handle 6 abuts against the release side 43 of cam bit 4 and fixture set 2；After loading onto workpiece 10, rotational handle 6, make the circular arc of cam bit 4 44 rotate along fixture set 2；It is turning lastly to lock side 42 and fixture set 2 abuts against, can be by chuck because distance B is more than distance A 1 locking, and it is plane-plane contact to lock side 42 and fixture set 2, its coupling mechanism force is big, is not easy to fail.

Embodiment above is only the preferred embodiment of this creation, all in this wound not to limit this creation Any modification, equivalent substitution and improvements for being done etc. within the spirit and principle of work, should be included in this creation protection domain it It is interior.
