Description

Fixture for machining center of reverse gear hole in gearbox case

technical field

The utility model relates to a jig for a machining center of a reverse gear hole of a gearbox housing, which is applied in the field of machining the reverse gear hole of a gearbox housing.

Background technique

During the production and processing of the gearbox case, it is necessary to process the reverse gear hole on the gearbox case. At present, the method used is to directly place the gearbox case on the machining center for the reverse gear hole of the gearbox case. Drilling, but the gearbox casing is a deformed part, so the gearbox casing will shake during processing, which will not only increase the difficulty of drilling, but also the precision of the processed reverse gear hole is not high.

Utility model content

In order to solve the defects of the prior art solutions, the utility model discloses a clamp for the machining center of the reverse gear hole of the transmission case which is easy to use and has high drilling precision.

The utility model discloses a fixture for the processing center of the reverse gear hole of a transmission case, which comprises: a bottom plate, a main positioning mandrel, a main positioning core sleeve, a secondary positioning mandrel, and a secondary positioning core sleeve. The main positioning mandrel is vertical directly welded on the bottom plate, the main positioning core sleeve is installed on the main positioning mandrel by threaded connection, the secondary positioning mandrel is welded vertically on the bottom plate, and the secondary positioning core sleeve is threaded The connection mode is installed on the secondary positioning mandrel.

Due to the above-mentioned technical scheme, the utility model has the following beneficial advantages:

1. Easy to use;

2. Good for drilling.

Description of drawings

Figure 1 is a structural schematic diagram of a clamp for the machining center of the reverse gear hole of the transmission case of the utility model.

Among them: 1-base plate; 2-main positioning mandrel; 3-main positioning core sleeve; 4-secondary positioning mandrel; 5-secondary positioning core sleeve.

Detailed ways

As shown in Figure 1, the utility model discloses a gear box reverse gear hole machining center fixture, including: a bottom plate 1, a main positioning mandrel 2, a main positioning core sleeve 3, a secondary positioning mandrel 4, and a secondary positioning core Cover 5, the main positioning mandrel 2 is vertically welded on the base plate 1, the main positioning core sleeve 3 is installed on the main positioning mandrel 2 through threaded connection, and the secondary positioning mandrel 4 It is vertically welded on the bottom plate 1, and the secondary positioning core sleeve 5 is installed on the secondary positioning mandrel 2 through screw connection.

The utility model is implemented in this way: first unscrew the main positioning core sleeve 3 from the main positioning mandrel 2, insert the main positioning mandrel 2 into the input shaft hole of the gearbox housing, and then place the secondary positioning core sleeve 5 Unscrew from the secondary positioning mandrel 4, insert the secondary positioning mandrel 4 into the output shaft hole of the gearbox housing, then reinstall the main positioning core sleeve 3 on the main positioning mandrel 2, and then rotate the main positioning core sleeve 3 Make the main positioning core sleeve 3 contact the upper surface of the gearbox housing, and continue to rotate the main positioning core sleeve 3 until the main positioning core sleeve 3 presses the gearbox housing on the bottom plate 1. In the same principle, place the secondary positioning core The sleeve 5 is installed on the secondary positioning mandrel 4 so that the secondary positioning core sleeve 4 will press the gearbox casing on the bottom plate 1, so that the gearbox casing is firmly fixed on the bottom plate 1, which is more convenient to use , and because the gearbox housing will no longer shake during the processing, it is beneficial to drilling, and the drilling accuracy is relatively high.

Finally, it should be noted that: the above embodiments are only used to illustrate the utility model rather than limit the technical solution described in the utility model; therefore, although the description has described the utility model in detail with reference to the above-mentioned various embodiments, Those of ordinary skill in the art should understand that the utility model can still be modified or equivalently replaced; and all technical solutions and improvements that do not depart from the spirit and scope of the utility model should be covered by the claims of the utility model in range.

Claims (1)
