Description
Technical field
The utility model relates to a kind of polishing rod, specifically a kind of valve tappet ball-and-socket polishing rod.
Background technology
All the time all very high to the roughness requirements on valve tappet ball-and-socket surface in industry, so all polishing will be carried out to ball-and-socket in process of production, traditional polishing adopts manual polishing exactly, namely staff holds sand paper and directly carries out polishing to valve tappet ball-and-socket, such polishing mode is not on the one hand owing to completing by stock removal polishing, will according to actual conditions polishing repeatedly, take time and effort, more inconvenience and waste is brought to operator, on the other hand owing to there is the error effect of artifact, just cannot ensure the accuracy of ball-and-socket size after polishing, affect product quality.
Utility model content
For the problems referred to above, the problem that the utility model quasi-solution is determined be to provide a kind of simple and reasonable, labour intensity is little, cost is low and the valve tappet ball-and-socket polishing rod that polishing efficiency is high, effectively ensures the accuracy of ball-and-socket size after polishing.
For achieving the above object, the utility model is by the following technical solutions: a kind of valve tappet ball-and-socket polishing rod, comprise connecting tube, rubber bar, sand paper and locking nut, a through hole is provided with in the middle of connecting tube, rubber bar one end is arranged in the through hole of described connecting tube, the other end stretches out outside described connecting tube, the described rubber bar length of stretching out outside connecting tube accounts for 1/3 of whole described rubber bar length, the described rubber bar top shape of stretching out outside connecting tube is spherical in shape, described rubber bar has wrapped sand paper, described connecting tube is arranged with locking nut, rubber bar and sand paper are clamped in described connecting tube by described locking nut.
As preferably, described connecting tube vertical sectional shape is the convex of 90 ° of turning clockwise.
As preferably, the material of described connecting tube is stainless steel.
Effective achievement of the present utility model: the utility model is simple and reasonable, cost is low, its structure is not only convenient to be installed in lathe, and no longer needs to carry out repeatedly polishing by hand, only needs once just can complete polishing requirement, greatly reduce labour intensity, improve polishing efficiency, add and be provided with flexible rubber bar, improve roughness after the durability of sand paper and polishing, after effectively ensureing polishing while ball-and-socket accuracy to size, ensure that the ball-and-socket roughness after processing reaches product requirement.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-connecting tube, 2-rubber bar, 3-sand paper, 4-locking nut, 5-through hole.
Detailed description of the invention
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the present embodiment, clear, complete description is carried out to the technical scheme in the utility model embodiment.
As shown in Figure 1, the utility model discloses a kind of valve tappet ball-and-socket polishing rod, comprise connecting tube 1, rubber bar 2, sand paper 3 and locking nut 4, a through hole 5 is provided with in the middle of connecting tube 1, rubber bar 2 one end is arranged in the through hole 5 of connecting tube 1, the other end stretches out outside connecting tube 1, rubber bar 2 length of stretching out outside connecting tube 1 accounts for 1/3 of whole rubber bar 2 length, rubber bar 2 top shape of stretching out outside connecting tube 1 is spherical in shape, rubber bar 2 wraps sand paper 3, connecting tube 1 is arranged with locking nut 4, rubber bar 2 and sand paper 3 are clamped in connecting tube 1 by locking nut 4, connecting tube 1 vertical sectional shape is the convex of 90 ° of turning clockwise, the material of connecting tube 1 is stainless steel.
The utility model is simple and reasonable, cost is low, its structure is not only convenient to be installed in lathe, and no longer needs to carry out repeatedly polishing by hand, only needs once just can complete polishing requirement, greatly reduce labour intensity, improve polishing efficiency, add and be provided with flexible rubber bar 2, improve roughness after the durability of sand paper 3 and polishing, after effectively ensureing polishing while ball-and-socket accuracy to size, ensure that the ball-and-socket roughness after processing reaches product requirement.
Obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of the utility model protection.
