Description

Technical Field

[0001] The utility model belongs to the technical field of diesel engine processing, and in particular relates to a fast positioning tool for a diesel engine junction box installation hole. Background Art

[0002] A junction box is a box used for collecting cables for various equipment such as power transmission, distribution, control and protection in the power system. It is a very important component of the electrical system and has the function of protecting electrical equipment and maintaining the safety of electricians.

[0003] The diesel engine junction box does not determine the installation position of the junction box, so it is necessary to determine the installation hole position on site according to the junction box size and host model during installation. In order to facilitate the installation of the diesel engine junction box, a positioning tool can be used.

[0004] At present, there are also some drilling positioning devices for diesel engine components, such as a diesel engine junction box installation hole quick positioning tool with application number CN202222450195.2. This type of device includes a positioning plate through the set frame, and the positioning plate is provided with a positioning hole. When the staff determines the reference point on the diesel engine body, they only need to align the positioning hole of the positioning plate with the reference point to use the positioning tool to determine the positions of the other three installation holes, which solves the problem of complex process and slow positioning speed when the conventional drilling positioning device determines other points through the reference point; a level is also provided. After the reference point position is determined to make the positioning tool initially positioned, the positioning tool can be adjusted to a level through the level so that the determined hole position can ensure the horizontal installation of the junction box, which solves the problem that the conventional drilling positioning device cannot ensure the horizontal installation of the junction box; the frame is installed with legs made of magnetic material, so that the frame can be adsorbed on the side wall of the diesel engine host for use. Combined with the slide ruler and the positioning plate, the present application can quickly and accurately locate the junction box installation hole on the side wall of the host, which solves the defect that the conventional drilling positioning device is difficult to be fixed on the side wall of the host for use.

[0005] In the conventional installation hole positioning method, the staff needs to first find a reference point on the side wall of the diesel engine host, and then use a tape measure to measure the positions of the other three installation holes from the reference point. After determining the positions of the installation holes, drilling can be performed; the conventional positioning method is not only time-consuming and labor-intensive, but also because the on-site working environment is messy and noisy, the position of the installation holes is easily deviated, resulting in the junction box cannot be horizontally installed on the side wall of the host. Repositioning delays the assembly progress and affects the appearance of the host.

[0006] During the use of this positioning tool, when the measured point is not on the same horizontal plane of the diesel engine, the measured position and the actual position are observed by naked eyes to see whether they are on the same vertical line. The measurement structure is not accurate enough, which may easily lead to a mismatch between the point and the punching position, making it impossible to install the junction box. Utility Model Content

[0011] In order to adjust the height of the alignment sleeve to facilitate the alignment of the points, as a preferred quick positioning tool for the installation hole of a diesel engine junction box of the utility model, a rotating structure is formed between the first threaded rod and the first bearing, the first threaded rod is threadedly connected with the adjusting bracket through the threaded hole, and the adjusting bracket is slidingly connected with the guide rod through the guide hole.

[0012] In order to facilitate the adjustment of the height of the threaded sleeve, as a preferred quick positioning tool for the installation hole of a diesel engine junction box of the utility model, the side surface of the longitudinal rod is connected to a second bracket, the surface of the second bracket is embedded with a second bearing, and the interior of the second bearing is penetrated by a second threaded rod.

[0013] In order to adjust the height of the magnetic support leg, as a preferred quick positioning tool for the installation hole of a diesel engine junction box of the utility model, the surface of the second threaded rod is sleeved with a threaded sleeve, the bottom of the threaded sleeve is connected to the magnetic support leg, the side surface of the threaded sleeve is connected to a guide sleeve, and the side surface of the second bracket close to the guide sleeve is connected to a guide rail.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] The utility model, after the position of the positioning tool is fixed, the longitudinal sliding rod is first pulled to slide, and then the transverse sliding sleeve is pulled to slide. After the position of the alignment sleeve is roughly determined, the first threaded rod can be rotated. Under the limiting action of the guide rod and the guide hole, the rotation of the first threaded rod can drive the adjusting bracket to move downward through the threaded hole. The downward movement of the adjusting bracket can drive the alignment sleeve to move downward. When the alignment sleeve is highly consistent with the measuring point, the position is adjusted. This can facilitate the measurement of the point position when other points are not in the same horizontal plane as the reference point, thereby improving the accuracy of the point position measurement.

[0017] The utility model adjusts the position of the positioning tool so that the alignment hole is aligned with the position of the reference point. Under the limiting action of the guide sleeve and the guide rail, the second threaded rod can drive the threaded sleeve to move downward when it rotates, and the downward movement of the threaded sleeve can drive the magnetic support leg to move downward. When the magnetic support leg moves to the surface position of the diesel engine, the magnetic support leg can be adsorbed on the surface of the diesel engine. In this way, the positioning tool can be positioned on the surface of the diesel engine, avoiding the positioning tool from tilting when the surface of the diesel engine is not horizontal.
