Problems solved by technology

[0002] The structure of the rocker arm of the car is relatively complicated, and there are many dimensions and matching dimensions, which increases the difficulty of acceptance
Existing methods usually use a measuring stick to measure, which often results in inaccurate dimensions, resulting in the inability to judge whether the processing size of the rocker arm is qualified
The existing common inspection method for the rocker arm is to measure the local size, which is difficult to ensure whether the overall size of the rocker arm meets the requirements
If you want to check the rocker arm as a whole, you need to check it by trial assembly, which is difficult, less feasible, and time-consuming.

Embodiment 1

[0058] Please refer to Figure 1-Figure 4 , a rocker arm inspection tool, including a base plate 1, a tailstock 2, a first connecting portion 4 for positioning one end of the rear rocker arm assembly 3, and a second connecting portion 5 for positioning the other end of the rear rocker arm assembly 3 and a plurality of end tube sockets 6;

[0059] The tailstock 2 is mounted on one end of the bottom plate 1;

[0060] A plurality of end sockets 6 are arranged symmetrically and installed on the end of the bottom plate 1 away from the tailstock 2;

[0061] The first connecting part 4 is inserted on the tailstock 2;

[0062] The second connecting part 5 is sequentially inserted on the plurality of end sockets 6 and the vertical horizontal planes of the second connecting part 5 and the first connecting part 4 are parallel to each other.

[0063] Preferably, there are two end pipe seats 6;

[0064] Specifically, the two end pipe seats 6 are installed on the bottom plate 1 in a sym...

Embodiment 2

[0080] The difference between this embodiment and the first embodiment is that another structure of the tailstock and the first connecting part is defined.

[0081] refer to Figure 5-Figure 8 , the top of the tailstock 2 is an inclined surface 21, the inclined surface 21 faces the side where the end pipe seat 6 is located and is gradually inclined outwardly from bottom to top;

[0082] The inclined surface 21 is provided with four third through-holes 211 which are distributed axially symmetrically;

[0083] Specifically, the bottom of the tailstock 2 is connected to the corresponding second bolt hole by bolts; each third through hole 211 is correspondingly inserted with a first connecting part 4, and the first connecting part 4 vertically passes through the rear rocker to be tested. One end of the arm assembly 3 is used to fix one end of the rear rocker arm assembly 3, and the lower end of the first connecting part 4 should be pressed against the bottom plate 1;

[0084] Wh...

Embodiment 3

[0086] An inspection method applied to the rocker inspection tool described in Embodiment 1 or Embodiment 2, comprising the following steps:

[0087] S1: installing the tailstock 2 and the end pipe seat 6 at corresponding positions on the bottom plate 1;

[0088] S2: install one end of the rear rocker arm assembly 3 to be inspected on the tailstock 2;

[0089] S3: inserting the first connecting part 4 horizontally and sequentially through the tail stock 2 and the one end of the rear rocker arm assembly 3 to be tested;

[0090] S4: install the other end of the rear rocker arm assembly 3 to be inspected on the corresponding end pipe seat 6;

[0091] S5: When the second connecting portion 5 can pass through the plurality of end pipe seats 6 and the other end of the rear rocker arm assembly 3 to be inspected sequentially, the rear rocker arm assembly 3 is considered qualified, Otherwise, the rear rocker arm assembly 3 is regarded as unqualified.

[0092] To sum up, the present ...

Abstract

The invention discloses a rocker arm checking fixture and a checking method. The rocker arm checking fixture comprises a bottom plate, a tailstock, a first connecting part for positioning one end of arear rocker arm assembly, a second connecting part for positioning the other end of the rear rocker arm assembly and a plurality of end pipe seats, wherein the tailstock is arranged at one end of thebottom plate; the plurality of end pipe seats are symmetrically arranged and are arranged at one end, far away from the tailstock, of the bottom plate; the first connecting part is inserted into thetailstock; the second connecting part is sequentially inserted into the plurality of end pipe seats, and the horizontal planes where the second connecting part and the first connecting part are located in the vertical direction are parallel to each other; one end of the rear rocker arm assembly is connected with the tailstock, the first connecting part is inserted into the tailstock, then the other end of the rear rocker arm assembly is connected with the end pipe seats, qualification rate inspection is conducted on the rear rocker arm assembly with the standard that whether the second connecting part can smoothly penetrate through the end pipe seats and the other end of the rear rocker arm assembly or not, accuracy is high, and inspection is convenient.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a rocker inspection tool and inspection method. Background technique [0002] The structure of the car rocker arm is relatively complicated, and there are many shapes and sizes and matching dimensions, which increases the difficulty of acceptance. Existing methods usually use a measuring stick to measure, which often results in inaccurate dimensions, which makes it impossible to judge whether the processed dimensions of the rocker arm are qualified. The existing common inspection method for the rocker arm is to measure the local size, which is difficult to ensure whether the overall size of the rocker arm meets the requirements. If the rocker arm is to be checked as a whole, it is checked by trial assembly, which is difficult, less feasible, and time-consuming. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rocker insp...
