Description

Technical Field

[0001] The utility model relates to the technical field of generator inspection tools, in particular to an integrated inspection tool for the distance between a belt pulley and a front hanging angle end face of a generator. Background Art

[0002] The power source of the generator is the engine, which is connected to the generator through a belt. The pulley installed at the end of the generator shaft drives the generator to work through the belt. For the convenience of manufacturing process and installation, the current automobile generators usually design the hanging angle on the mounting bracket of the front cover. Therefore, the distance between the first groove of the pulley (the first groove from the inside to the outside in the direction away from the generator) and the end face of the front hanging angle (the distance is as follows Figure 1 The marked line segment L) shown in the figure needs to be set within the error range. If the spacing is not within the error range, the vehicle cannot be installed. Therefore, it is very important to measure the spacing between the first groove of the pulley and the end face of the front hanging angle before installation.

[0003] During measurement, since the first groove of the pulley and the end face of the front hanging angle are not on the same plane, direct measurement is impossible. Currently, the distance between the first groove of the pulley and the end face of the front hanging angle is usually measured by first using a square opening piece to be clamped in the first groove of the pulley, and a measuring rod parallel to the front hanging angle is extended to the outside of the square opening piece. A vernier caliper is then used to clamp the measuring rod and the end face of the front hanging angle to read the reading, and then the width of the measuring rod is subtracted. In this way, the two tools are used in conjunction with each other to measure the distance, which cannot be completed by a single operator and is time-consuming and laborious. Utility Model Content

[0004] In order to solve the technical problems existing in the background technology, the utility model provides an integrated inspection fixture for the distance between the pulley and the front hanging angle end face of a generator.

[0005] The utility model proposes an integrated inspection tool for the distance between a pulley and the end face of a front hanging angle of a generator, comprising a square opening piece that can be stuck in a pulley groove, the opening of the square opening piece extends outwardly close to a side of the front hanging angle and is connected to a U-shaped measuring piece, the square opening piece and the U-shaped measuring piece are arranged as an integrated structure, the opening size of the U-shaped measuring piece is determined according to a spacing setting value, and the spacing setting value is a spacing value between the first groove of the pulley and the end face of the front hanging angle that meets the installation requirements, and after the square opening piece is stuck in the pulley groove, if the U-shaped measuring piece can just be stuck on the end face of the front hanging angle, the spacing setting requirements are met.

[0006] Preferably, the opening of the square opening piece is arranged in the middle of one side of the long side of the square opening piece, and meshing teeth matching the pulley groove are arranged on the inner walls on both sides of the opening.

[0007] Preferably, a groove is provided on the outer inner wall of the U-shaped measuring piece, and a boss extending along the side of the U-shaped measuring piece is provided in the middle of the groove. The outer contour of the boss extends beyond the groove, and when the U-shaped measuring piece is clamped on the end face of the front hanging angle, the outer end face of the boss just contacts with the end face of the front hanging angle.

[0008] Preferably, an arc-shaped groove transition is provided between the groove and the bottom inner wall of the U-shaped measuring piece.

[0009] To sum up, the utility model has the following beneficial effects: the square opening piece and the U-shaped measuring piece are set as an integrated structure, which can be operated by one person, saving labor costs. Before detection, the opening size of the U-shaped measuring piece is determined according to the size of the spacing setting value, and then the square opening piece is first clamped in the first groove of the pulley. If the U-shaped measuring piece can be clamped on the end face of the front hanging angle, it meets the spacing setting requirements; if the U-shaped measuring piece cannot be clamped on the end face of the front hanging angle, it does not meet the spacing setting requirements (which will affect the subsequent loading). After the detection, it is easy to know whether the loading can be completed without calculating the specific spacing value, which is convenient for detection and saves time and effort.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0018] like Figure 1-4 As shown, the embodiment proposes an integrated inspection fixture for the distance between the pulley and the end face of the front hanging angle of the generator, which is used to detect whether the distance value L between the first groove of the pulley 1 and the end face of the front hanging angle 2 meets the installation requirements, and includes a square opening piece 3 that can be stuck in the groove of the pulley 1, and the opening of the square opening piece 3 extends outward near the side of the front hanging angle 2 and is connected with a U-shaped measuring piece 4, the square opening piece 3 and the U-shaped measuring piece 4 are set as an integrated structure, and the opening size of the U-shaped measuring piece 4 is determined according to the distance setting value, and the distance setting value is the distance value between the first groove of the pulley 1 and the end face of the front hanging angle 2 that meets the installation requirements. After the square opening piece 3 is stuck in the pulley groove, if the U-shaped measuring piece 4 can just be stuck on the end face of the front hanging angle 2, it means that the distance setting requirements are met.

[0019] In this way, the square opening piece 3 and the U-shaped measuring piece 4 are set as an integrated structure, which can be operated by one person, saving labor costs. Before detection, the opening size of the U-shaped measuring piece 4 is determined according to the size of the spacing setting value, and then the square opening piece 3 is first stuck in the pulley groove from the first groove of the pulley 1. If the U-shaped measuring piece 4 can be stuck on the end face of the front hanging angle 2, it meets the spacing setting requirements; if the U-shaped measuring piece 4 cannot be stuck on the end face of the front hanging angle 2, it does not meet the spacing setting requirements (which will affect the subsequent loading). After the detection, it is easy to know whether the loading can be completed without calculating the specific spacing value, which is convenient for detection and saves time and effort.

[0020] Furthermore, if Figure 2 and Figure 4 As shown, the opening of the square opening piece 3 is arranged in the middle of one side of the long side of the square opening piece 3, and the inner walls on both sides of the opening are provided with meshing teeth 5 matching the pulley grooves, and each meshing tooth 5 meshes with each groove in sequence starting from the first groove of the pulley 1, so that the square opening piece 3 is stuck in the pulley groove to avoid being separated from the pulley groove and affecting the detection work.

[0021] Furthermore, a groove 6 is provided on the inner wall of the outer side of the U-shaped measuring piece 4, and a boss 7 extending along the side of the U-shaped measuring piece 4 is provided in the middle of the groove 6, and the outer contour of the boss 7 exceeds the groove 6. When the U-shaped measuring piece 4 is clamped on the end face of the front hanging angle 2, the outer end face of the boss 7 just contacts the end face of the front hanging angle 2. In this way, the arrangement of the groove 6 and the boss 7 can conveniently clamp the U-shaped measuring piece 4 on the end face of the front hanging angle 2 or detach from the end face of the front hanging angle 2.

[0022] An arc groove 8 is provided between the groove 6 and the bottom inner wall of the U-shaped measuring piece 4 for transition.
