Description

Hole Drilling Device for Batch Processing of Cross Recessed Gears

technical field

The utility model relates to a hole processing device, in particular to a cross groove gear batch processing hole drilling mold device, which belongs to the technical field of mechanical processing and manufacturing.

Background technique

With the continuous development of industrial design, customers have more and more requirements for the diversity of product workpiece design, and there are often requirements for processing various holes on the workpiece, and accurate processing accuracy is required. In the prior art, when machining holes on disk workpieces, manufacturers generally adopt the following methods:

1. Use the machining center to process to the requirements of the drawings. This method has high precision. Generally, the shape and position tolerance requirements of the holes can be guaranteed. However, since each workpiece needs to be clamped and corrected, the processing efficiency is not high. And because the machining center is a finishing equipment, many workpieces require the machining center to complete the corresponding process, which may easily lead to unreasonable production arrangements, resulting in low overall production capacity.

2. The ordinary drilling machine is used for processing, but the ordinary drilling machine cannot automatically and accurately find the position of the hole. The hole position must be completely determined by other methods before drilling. Pre-holes are processed by a drilling machine, so the efficiency is very low.

For the cross groove gear (shown in Figure 1), since it is also a disc type workpiece, the above method can only be used to process holes in the cross groove part, which is difficult to meet the requirements of improving work efficiency and reducing production costs during mass production .

Contents of the invention

The purpose of the utility model is to overcome the deficiencies in the prior art, and provide a cross-recessed gear batch processing hole drilling device, which has a simple structure, is used in conjunction with an ordinary drilling machine, is easy to operate, safe and reliable, and can be clamped at one time It can complete the processing of multiple holes, and can ensure that the shape and position tolerances of the holes in the cross groove meet the requirements, greatly improving work efficiency and reducing production costs. It is suitable for batch processing holes of this type of gear.

According to the technical solution provided by the utility model: the cross-recessed gear batch processing hole drilling device is characterized in that: it includes a positioning base, a positioning side plate, a positioning shaft, a positioning pin, an upper pressure plate and a drill sleeve; the base is used to be fixed on the On the workbench of an ordinary drilling machine, the positioning side plate is fixed on the base, and the positioning side plate is perpendicular to the base; the center of the fixed side plate is installed with a positioning shaft vertically penetrating through the fixed side plate, and the two ends of the positioning shaft are equipped with The lock nut, the positioning shaft is used to fix the cross-recessed gear on the positioning side plate; the positioning pin is arranged beside the positioning shaft, the positioning pin is vertically fixed on the positioning side plate, and the positioning pin is used to embed the cross groove of the gear In the groove, the rotation of the cross-recessed gear is restricted; the pressure plate is fixedly installed on the top of the positioning side plate, the front of the pressure plate is located above the cross groove of the gear, and the drill sleeve is embedded in the front of the pressure plate. The position of the drill sleeve is the same as that of the cross-recessed gear. The position of the hole to be processed on the drill sleeve corresponds to the shape and position tolerance of the inner hole of the drill sleeve and the shape and position tolerance of the hole to be processed on the cross groove gear.

Compared with the prior art, the utility model has the following advantages:

(1) The utility model has a simple structure, and can be used with an ordinary drilling machine. It is easy to operate, safe and reliable, and can effectively and reliably fix the workpiece (cross groove gear), eliminate the unqualified hole position caused by the walking of the workpiece, and ensure the shape and position of the hole The tolerance meets the requirements, which greatly improves the processing stability and improves the processing quality.

(2) The utility model can complete the processing of multiple holes in one clamping, which greatly improves the work efficiency and reduces the production cost, and is suitable for batch processing holes of this type of gear.

(3) The utility model has wide application range, long service life and low manufacturing cost.
