Technical Field

The utility model relates to the technical field of thimbles, in particular to a brass thimble.

Background

The brass thimble is widely applied to high-precision products due to good performance. But current brass thimble is because of its specification is great, can't be applicable to multiple use occasion, and simultaneously, brass thimble and other parts cooperativeness are also relatively poor. In view of the above problems, no effective solution has been proposed.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: provides a brass thimble to solve the problems in the prior art.

The technical scheme is as follows: a brass thimble, comprising: a fixed part; a support part connected with the fixing part; the extension part is fixedly connected with the support part; a pyramid part fixedly arranged at one end of the extension part; the blind hole is formed in one side of the supporting part; the fixing part, the supporting part, the extending part and the cone part are integrally formed, and blind holes are formed in the fixing part, the supporting part, the extending part and the cone part so as to be matched with other parts.

Preferably, a countersunk hole is formed at one end of the fixing part.

Preferably, the fixing portion, the support portion, the extension portion, and the tapered portion are provided in a stepped shape, and an outer diameter of the tapered portion decreases from the fixing portion.

Preferably, a transition chamfer is provided between the support portion and the extension portion.

Preferably, a step is provided between the fixing portion and the support portion.

Preferably, the fixing portion, the support portion, the extension portion, and the tapered portion are coaxially provided.

Preferably, the diameter of the extension part is within the range of phi 0.77mm to phi 0.79 mm.

Has the advantages that: in this application embodiment, adopt integrated into one piece's mode, through the fixed part the supporting part the extension with pyramis integrated into one piece to and through having seted up the blind hole, with other part cooperations, reached the purpose that reduces brass thimble volume, thereby realized improving the thimble and used the flexibility ratio and with other part cooperation degree's technological effect, and then solved current brass thimble because of its specification is great, can't be applicable to multiple use occasion, simultaneously, brass thimble and other part cooperativeness also relatively poor technical problem.

The reference signs are: 1. a fixed part; 2. a support portion; 3. an extension portion; 4. a pyramid part; 5. blind holes; 6. a countersunk hole; 7. transition chamfering; 8. and (4) a step.

Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the utility model.

As shown in fig. 1, the present application relates to a brass thimble. This brass thimble includes: a fixed part 1; the fixing part 1 is a fixing bottom part, so that a good fixing and supporting effect can be realized, and meanwhile, the effect of matching with other parts can also be realized; a support part 2 connected to the fixing part 1; the thimble has the advantages that a good fixed connection effect can be realized, and meanwhile, a good supporting effect can be realized, so that the strength of the thimble is improved; an extension part 3 fixedly connected with the support part 2; good extension effect can be realized, so that the matching degree with other parts is improved; further, the diameter of the extension part 3 is within the range of phi 0.77mm to phi 0.79 mm. A good fitting effect can be ensured. A tapered part 4 fixedly provided at one end of the extension part 3; the effect of facilitating the connection with the component can be achieved, thereby preventing the occurrence of interference; the blind hole 5 is formed in one side of the supporting part 2; the effect of matching with other parts can be realized, so that the adaptability of the thimble is improved; preferably, the diameter interval of the blind hole is phi 0.55mm to phi 0.65 mm. Good matching effect can be realized.

The fixing part 1, the supporting part 2, the extending part 3 and the cone part 4 are integrally formed, and blind holes 5 are formed to match with other components. Adopt integrated into one piece's mode, can also prevent that the thimble from causing the volume too big because of the assembly when can guaranteeing thimble self intensity to influence the assembly effect with other parts. Simultaneously, still seted up blind hole 5, can further improve the effect of adaptation, can also improve the stability of structure.

From the above description, it can be seen that the following technical effects are achieved by the present application:

in this application embodiment, adopt integrated into one piece's mode, through fixed part 1 the supporting part 2 extension 3 with 4 integrated into one piece in pyramis to and through having seted up blind hole 5, in order to cooperate with other parts, reached the purpose that reduces the brass thimble volume, thereby realized improving the thimble and used the technical effect of flexibility ratio and with other part cooperativeness, and then solved current brass thimble because of its specification is great, can't be applicable to multiple use occasion, simultaneously, brass thimble and other parts cooperativeness also relatively poor technical problem.

Furthermore, a countersunk hole 6 is formed at one end of the fixing part 1. Through being provided with counter bore 6, can realize further with other part complex effects to improve the stability of brass thimble.

Further, the fixing portion 1, the support portion 2, the extension portion 3, and the tapered portion 4 are provided in a stepped shape, and the outer diameter decreases from the fixing portion 1 to the tapered portion 4. Can realize good cooperation effect to realize the effect of being convenient for assemble and fix.

Further, a transition chamfer 7 is arranged between the support part 2 and the extension part 3. The situation of interference can be prevented, and the effect of convenient assembly is realized.

Further, a step 8 is provided between the fixing portion 1 and the supporting portion 2. Can realize good block effect to realize the fixed effect of being convenient for.

Further, the fixing portion, the supporting portion, the extending portion, and the tapered portion are coaxially disposed. Good coaxiality can be ensured, so that the precision of the brass thimble is improved. Preferably, the coaxiality is φ 0.05. Good coaxial effect can be ensured.

The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, however, the present invention is not limited to the specific details of the embodiments, and various equivalent changes can be made to the technical solution of the present invention within the technical idea of the present invention, and these equivalent changes are within the protection scope of the present invention.
