Description

A kind of production line of bar rolling line dc motor carbon brush changes spanner

Technical field

This utility model is related to a kind of spanner, and more particularly to a kind of production line of bar rolling line dc motor carbon brush is changed Spanner.

Background technology

Need to change after production line of bar rolling line dc motor carbon brush mill is short, as yield is higher, change carbon brush frequently, But narrow space between brush holder and motor housing in motor, common wrench are put to good use not open, change difficult, change needs every time a large amount of Time.

The content of the invention

To solve problem above, this utility model provides a kind of production line of bar that can be accurate, quick, convenient, safe Rolling line dc motor carbon brush changes spanner.

It is that, up to above-mentioned purpose, a kind of production line of bar rolling line dc motor carbon brush of this utility model changes spanner, its bag Include handle, bearing pin, wrenching bar, hexagon socket head cap screw and hexagon socket head cap screw bar, the hexagon socket head cap screw bar bottom and described interior six Angle screw connection, top are connected at an angle of 90 with one end of the wrenching bar, the spanner lever pin other end by the bearing pin with The handle rotates connection.

Wherein described hexagon socket head cap screw bar is welded with the wrenching bar.

This utility model difference from prior art is that this utility model achieves following technique effect：

1st, this utility model is changed spanner to solve space between carbon brush and motor housing little, what common wrench was put to good use not open Problem, the carbon brush of replacing production line dc motor that can be accurate, quick, convenient, safe；

2nd, the time for changing carbon brush is shortened using this utility model spanner, has striven for more rolling times, it is ensured that produce Amount.

The utility model is described in further detail below in conjunction with the accompanying drawings.

Description of the drawings

Fig. 1 is the structural representation that this utility model production line of bar rolling line dc motor carbon brush changes spanner；

Fig. 2 is the top view that this utility model production line of bar rolling line dc motor carbon brush changes spanner.

Description of reference numerals：1- handles, 2- bearing pins, 3- wrenching bars, 4- hexagon socket head cap screws, 5- hexagon socket head cap screw bars.

Specific embodiment

It is below in conjunction with drawings and Examples, above-mentioned to this utility model to make more detailed with other technical characteristic and advantage Explanation.

As illustrated in fig. 1 and 2, a kind of production line of bar rolling line dc motor carbon brush of this utility model changes spanner, including Handle 1, bearing pin 2, wrenching bar 3, hexagon socket head cap screw 4 and hexagon socket head cap screw bar 5,5 bottom of hexagon socket head cap screw bar and interior six Angle screw 4 connects, and one end of top and wrenching bar 3 is welded at an angle of 90, and the bearing pin 2 is by the other end of wrenching bar 3 with handle 1 Connection, handle 1 and wrenching bar 3 by 2 maximum of rotatable bearing pin can 90 ° of angles of doubling, when needing using this instrument Hexagon socket head cap screw 4 need to be enclosed within the outer-hexagonal screw for needing fastening, handle 1 be turned up by rotatable bearing pin 2, is directly revolved Handle handss 1 can reach the purpose for tightening or loosening.

Embodiment described above is only that preferred implementation of the present utility model is described, not to this practicality New scope is defined, and on the premise of without departing from this utility model design spirit, those of ordinary skill in the art are to this Various modifications and improvement that the technical scheme of utility model is made, all should fall into the protection of this utility model claims determination In the range of.
