Description

A kind of universal joint boring row

Technical field

The utility model is related to boring row technical field, and in particular to a kind of universal joint boring row.

Background technology

Generally, boring row is to be rigidly connected with taper shank, finds that boring row and bearing shell very easily wear and tear during use, Causing bearing shell and boring row often needs to change, and has a strong impact on product quality and processing efficiency.

This is directed to, it is necessary to make improvement.

Utility model content

The utility model provides a kind of universal joint boring row.

A kind of universal joint boring row, including taper shank and boring row, the boring row left end are boring row joint, also including universal joint, The universal joint is connected between the boring row joint and taper shank.

Further, also including three middle nodes, respectively the first middle node, the second middle node and the 3rd middle node, from It is left-to-right to be sequentially connected taper shank, the first middle node, the second middle node, the 3rd middle node and boring row, in the middle of the taper shank and first By the connection of the first bearing pin, the first middle node right-hand member is connected section left end with the second middle node left end by the second bearing pin, and described the Two middle node right-hand members are connected with the left end of the 3rd middle node by the 3rd bearing pin, the right-hand member of the 3rd middle node with it is described Boring row joint is connected by the 4th bearing pin.

Further, it is solid with nut after the right-hand member of the 3rd middle node is connected with the boring row joint by the 4th bearing pin It is fixed.

Further, parallel, the axis phase of first bearing pin and the second bearing pin of second bearing pin and the 3rd bearing pin It is mutually vertical.

Further, the bottom of first bearing pin and the second bearing pin is provided with fastener.

Further, the fastener is circlip for shaft.

Further, first bearing pin, the second bearing pin and the 3rd bearing pin shape size are consistent.

The utility model has the advantage of：By setting three middle nodes, can be rotated in three directions by middle node, pole It is big to reduce boring row outer radial stress in process, make to be rotated in bearing shell under boring row free state.Put into practice according to our factory This boring row processing stabilization, reliability are proved, boring row and bearing bush abrasion are small, meet batch production requirements.

Brief description of the drawings

Fig. 1 is the utility model main structure diagram.

Specific embodiment

It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer Accompanying drawing in type embodiment, is clearly and completely described, it is clear that retouched to the technical scheme in the utility model embodiment The embodiment stated is a part of embodiment of the utility model, rather than whole embodiments.Based on the implementation in the utility model Example, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made is belonged to The scope of the utility model protection.

With reference to accompanying drawing 1, a kind of universal joint boring row of the utility model, including taper shank 1 and boring row 2, the left end of the boring row 2 is Boring row joint 3, also including universal joint, the universal joint is connected between the boring row joint 3 and taper shank 1；

Specifically, the universal joint includes three middle nodes, in respectively the first middle node 4, the second middle node 5 and the 3rd Segmentum intercalaris 6, is from left to right sequentially connected taper shank 1, the first middle node 4, the second middle node 5, the 3rd middle node 5 and boring row 2, the cone Handle 1 is connected with the left end of the first middle node 4 by the first bearing pin 7, and the right-hand member of the first middle node 4 and the left end of the second middle node 5 are by the Two bearing pins 8 are connected, and the right-hand member of the second middle node 5 is connected with the left end of the 3rd middle node 6 by the 3rd bearing pin 9, described The right-hand member of the 3rd middle node 5 is connected with the boring row joint 3 by the 4th bearing pin 10, and is fixed with nut 11；

Further, second bearing pin 8 is parallel with the 3rd bearing pin 9, the axle of the bearing pin 8 of first bearing pin 7 and second Line is mutually perpendicular to, and can improve rotational angle；

Further, the bottom of the bearing pin 8 of first bearing pin 7 and second is provided with circlip for shaft 12, improves wearability； First bearing pin 7, the second bearing pin and the shape size of 8 the 3rd bearing pin 9 are consistent, convenient for assembly.

It should be noted that herein, such as first and second or the like relational terms are used merely to a reality Body or operation make a distinction with another entity or operation, and not necessarily require or imply these entities or deposited between operating In any this actual relation or order.And, term " including ", "comprising" or its any other variant be intended to Nonexcludability is included, so that process, method, article or equipment including a series of key elements not only will including those Element, but also other key elements including being not expressly set out, or also include being this process, method, article or equipment Intrinsic key element.In the absence of more restrictions, the key element limited by sentence "including a ...", it is not excluded that Also there is other identical element in process, method, article or equipment including the key element.

Above example is only used to illustrate the technical solution of the utility model, rather than its limitations；Although with reference to foregoing reality Example is applied to be described in detail the utility model, it will be understood by those within the art that：It still can be to preceding State the technical scheme described in each embodiment to modify, or equivalent is carried out to which part technical characteristic；And these Modification is replaced, and does not make the spirit and model of essence disengaging each embodiment technical scheme of the utility model of appropriate technical solution Enclose.
