Detailed Description

In order to make the utility model realize, the technical means, the creation characteristics, the achievement purpose and the efficacy are easy to understand and understand, the utility model is further explained by combining the specific implementation mode.

As shown in fig. 1 to 5, a signal wheel 5 angle gauge dedicated for a dual mass flywheel comprises a base 1, wherein a positioning assembly 2 for fixing the flywheel is arranged on the base 1, and an error-proof assembly 3 and a detection assembly 4 are arranged on the right side of the positioning assembly 2; the mistake proofing component 3 is arranged on the front side of the detection component 4; the error-proofing component 3 is used for determining the position of a notch 51 in the flywheel, and the detection component 4 is used for detecting the deflection angle of a lower side edge 52 of a signal tooth below the notch 51.

In this embodiment, the positioning assembly 2 includes a supporting plate 21, the supporting plate 21 is fixedly connected to the upper surface of the base 1 through a screw, the supporting plate 21 is used for supporting the flywheel, a central spindle 22 for positioning the center of the flywheel is disposed at the center of the supporting plate 21, a positioning pin 23 fixedly connected to the base 1 is disposed on the outer side of the spindle 22, the top end of the positioning pin 23 penetrates through the supporting plate 21, and a positioning hole for positioning the positioning pin 23 is disposed on the flywheel.

In this embodiment, mistake proofing subassembly 3 includes mistake proofing slider 31 and fixing base 32, fixing base 32 passes through screw and 1 fixed connection of base, be equipped with the spout in the fixing base 32, in mistake proofing slider 31 sliding connection and the spout, and the centre of a circle of the directional dabber 22 of centre line. As shown in fig. 4, the error-proof slider 31 can be inserted into the notch 51 only when the position of the notch 51 is above the measuring slider 42, thereby distinguishing whether the signal wheel 5 is reversely mounted.

In this embodiment, the detecting assembly 4 includes an equal-height seat 41 and a measuring slide block 42, the equal-height seat 41 is fixedly connected with the base 1 through a screw, the measuring slide block 42 is slidably connected with the equal-height seat 41, and a vertical reference line 422 and a reference plane 423 are arranged at a front end of the measuring slide block 42. The lower edge 52 of the signal tooth below the notch 51 is pointed to indicate that the angle is acceptable as long as it floats within the range between the upper and lower ends of the vertical reference line 422.

In this embodiment, the measuring slide 42 is provided with a limiting groove 421, the equal-height seat 41 is fixedly connected with a positioning column 43, and the positioning column 43 is slidably connected in the limiting groove 421. Thereby controlling the sliding stroke of the measuring slide 42 within a certain range.

The working process and the principle thereof are as follows:

the signal wheel 5 of the flywheel is mounted on the flywheel, and when in use, the notch 51 of the signal wheel 5 needs to be ensured to be matched with a certain part of the engine. The flywheel is provided with a positioning hole as a reference, and when the signal wheel 5 is installed, the angle of the signal wheel 5 installed on the flywheel needs to be limited within a certain error range by taking the positioning hole as the reference. Ensuring that no errors occur when the flywheel is assembled to the vehicle.

When the detection gauge is used, the flywheel is firstly positioned and fixed through the positioning pin 23, the mandrel 22 and the support sheet.

When the signal wheel 5 is assembled on the flywheel, sometimes the front and back sides of the signal wheel 5 are mistaken due to the error of a worker, so that after the assembled signal wheel 5 and the flywheel are placed on the positioning assembly 2, the notch 51 is located below the measuring slide block 42, and even if the measuring result of the measuring slide block 42 is qualified, the installation of the signal wheel 5 is still unqualified.

Therefore, a mistake-proofing slider 31 is arranged, after the flywheel is positioned, the mistake-proofing slider 31 is pushed, and only when the notch 51 of the signal tooth is positioned above the measuring slider 42, the front end of the mistake-proofing slider 31 can be inserted into the notch 51, so that the signal wheel 5 is ensured not to be reversely mounted.

Only then can the detection work be performed, the measuring slide 42 is pushed, so that the measuring slide 42 moves to the extreme position towards the direction of the flywheel, and the limit groove 421 is used for limiting the extreme position of the measuring slide 42.

When the slide block 42 to be measured moves to the extreme position, whether the edge 52 of the nearest signal tooth below the notch 51 points to the position between the upper end point and the lower end point of the vertical reference line 422 is observed, whether the position angle of the notch 51 is qualified can be judged according to the angle position of the edge 52 of the signal tooth, and therefore whether the installation angle of the whole signal wheel 5 is qualified is judged.

If edge 52 is oriented between the upper and lower endpoints of vertical reference line 422, the angle is acceptable, whereas edge 52 is not acceptable if it is in contact with reference plane 423 or if it is above the upper endpoint of the reference line.

Based on the above: the detection gauge is simple in structure, convenient and fast to use, easy to process and manufacture in a large number, and is more suitable for batch detection of products in factories compared with detection of existing large-scale equipment without pertinence such as three-coordinate equipment, detection cost is greatly saved, and detection efficiency is further improved.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of the invention or which are equivalent to the scope of the invention are embraced by the invention.
