SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's is not enough, provides and fixes the left straight section of big connecting rod through fixed block and kicking block, stretches into slope section below and observes the two relative surface laminating degree and judge whether the angle of inclination meets the requirements a big connecting rod angle of sewing machine transmission examines utensil through the slope piece that can stretch out and draw back.
The utility model adopts the technical proposal that:
the utility model provides an utensil is examined to big connecting rod angle of sewing machine transmission which characterized in that: including base, fixed block, kicking block and slope piece, one side rear end of base sets up the fixed block, sets up the kicking block at the fixed block front end, is used for pressing from both sides the left straight section of tight big connecting rod between fixed block and the kicking block, sets up the slope piece in base opposite side rear end, and the slope piece side is provided with the reference column that is used for fixed big connecting rod trompil section, and the slope piece can transversely stretch out to the right side.
The surface of the inclined block facing the front end of the base is an inclined surface, the angle of inclination of the inclined surface with respect to the horizontal plane is the angle of inclination required by the bottom surface of the inclined section, and the inclined surface is used for angle comparison with the bottom surface of the inclined section of the large link located there.
Furthermore, base opposite side rear end is provided with flexible box, transversely sets up the telescopic link in this flexible box, and telescopic link left side tip is located flexible box left side outside, and telescopic link right side tip is located flexible box right side outside and connects the slope piece, the outer fringe cover that the telescopic link is located flexible box are equipped with pressure spring or extension spring.
The utility model has the advantages that:
in the utility model, the left side of the base is provided with the fixed block and the top block, the right side of the base is provided with the inclined block and the positioning column, the fixed block and the top block clamp the straight section on the left side of the big connecting rod, the positioning column is sleeved in the open hole section on the right side of the big connecting rod, the inclined block is driven by the telescopic rod and moves transversely, when the inclined block can extend into the inclined section below the position, the gap between the inclined plane of the inclined block and the bottom surface of the inclined section is observed, if the gap is small or even not, the inclination angle of the bottom surface of the inclined section is considered to be in accordance with the requirement, if the gap is large, the inclination angle of the bottom surface of the inclined section is considered to be not in accordance with the requirement, if the inclined block can not completely enter into the inclined section below the big connecting rod, the inclination angle of the bottom surface, and the judgment result is accurate.

Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic view of the tilting block of fig. 1 extending below the tilting segment.
Detailed Description
The present invention is further illustrated by the following examples, which are intended to be illustrative, not limiting and are not intended to limit the scope of the invention.
The utility model provides an utensil is examined to big connecting rod angle of sewing machine transmission, as shown in fig. 1, 2, the utility model discloses an innovation lies in: including base 2, fixed block 3, kicking block 5 and sloping block 13, one side rear end of base is provided with cushion 1, set up the fixed block in the cushion rear end, set up the kicking block on the cushion of fixed block front end, be used for pressing from both sides tight left straight section 4 of big connecting rod between fixed block and the kicking block, set up the sloping block in base opposite side rear end, the sloping block side is provided with the reference column 16 that is used for fixed big connecting rod trompil section 11, the sloping block can transversely stretch out to the right side.
In this embodiment, the left side of the inclined block and the right side of the fixed block are provided with an arc section 6 and a straight section 7 of the large connecting rod, and the right side of the inclined block is provided with a bending section 8 of the large connecting rod.
The surface of the inclined block facing the front end of the base is an inclined surface 12, the inclined surface has an inclination angle relative to the horizontal plane required by the bottom surface 9 of the inclined section 10, and the inclined surface is used for angle comparison with the bottom surface of the inclined section of the large connecting rod positioned at the inclined surface.
The base opposite side rear end is provided with flexible box 14, transversely sets up telescopic link 15 in this flexible box, and telescopic link left side tip is located flexible box left side outside, and telescopic link right side tip is located flexible box right side outside and connects the sloping block, and the outer fringe cover that the telescopic link is located flexible box is equipped with pressure spring or extension spring. The effect of pressure spring is compressed when the telescopic link moves to the right side, and when the telescopic link loosens the back, the pressure spring can make the telescopic link reset to the left side. The effect of extension spring is that the telescopic link is stretched when moving to the right side, and when the telescopic link unclamped the back, the extension spring enabled the telescopic link to reset to the left side.
The utility model discloses a measurement process is:
the left side of the large connecting rod is fixed between the fixed block and the top block, the right side of the large connecting rod is sleeved on the positioning column, and the telescopic rod is pushed to the right side to enable the inclined block to move below the inclined section. The judgment is as follows according to specific conditions:
1. when the tilting block can be extended below the tilting section located there as shown in fig. 2, the gap between the tilting face of the tilting block and the bottom face of the tilting section is observed.
If the gaps are small or even no gaps exist, the bottom surface inclination angle of the inclined section is considered to meet the requirements;
and secondly, if the gap is large, the inclined angle of the bottom surface of the inclined section is not in accordance with the requirement.
2. When the inclined block can not enter the lower part of the inclined section of the large connecting rod at all, the bottom surface inclined angle of the inclined section is considered to be not in accordance with the requirement.
The utility model discloses in, the piece that inclines is driven and lateral shifting by the telescopic link, changes the measurement at slope section bottom surface angle of inclination into the laminating degree of piece and slope section, not only need not loaded down with trivial details protractor and measures, and the judged result is accurate moreover.
