Description

Technical Field

[0001] The invention relates to the field of production and processing of automobile parts, in particular to a special processing device for double countersunk holes of a generator bracket. Background Art

[0002] The generator bracket is one of the parts used to support and fix the generator on the car. During manufacturing, most large motor brackets are cast in one piece and then fine-machined. Among them, the two countersunk holes of the generator bracket need to be bored. This requires corresponding fixtures and processing equipment.

[0003] At present, there is no good processing equipment to bore the double countersunk holes of the generator bracket. As for the fixing technology, the Chinese utility model patent with application number 202111243823.3 proposes a fixture for processing the generator bracket. By combining the fixing component, positioning component, clamping component, limit component and auxiliary component, the generator bracket can be clamped and fixed from multiple directions. The clamping method is diverse, which avoids the movement of the generator bracket and is more suitable for promotion and use. However, it is quite complicated to use and it is difficult to clamp a specific generator bracket. Summary of the invention

[0004] In order to overcome the defects of the traditional technology and realize the clamping of the generator bracket and the boring of the double countersunk holes of the generator bracket, the present invention proposes a special processing device for the double countersunk holes of the generator bracket.

The integrated cabinet is also provided with a waste trough. When the generator bracket is installed, the double countersunk holes of the generator bracket will be located directly above the waste trough, so as to facilitate the collection and processing of processing waste. The boring implementation component can control the boring tool to bore the double countersunk holes of the generator bracket. The positioning pin and the positioning block are used to position the generator bracket, and the clamping control component can clamp and fix the generator bracket, and the right part of the main pressure plate is used to clamp the generator bracket.

That is, the rear platform, the round shaft, the square shaft and the boring tool are driven to lift and lower through the lead screw nut transmission mode, thereby implementing subsequent boring processing.

[0012] As a further improvement of the present invention, the rear platform is connected to a lead screw, and the lead screw is rotatably mounted on the rear hanger. The above structure is a conventional design.

[0013] As a further improvement of the present invention, the rotation transmission assembly is composed of a rotating sleeve mounted on the rear hanger through a bearing and a transmission assembly connected between the rotating sleeve and the double-headed motor. The transmission assembly transmits the rotation power provided by the double-headed motor to the rotating sleeve.

[0014] As a further improvement of the present invention, the square shaft is slidably mounted in the rotating sleeve, that is, the square shaft can rotate together with the rotating sleeve and can also slide relative to the rotating sleeve.

[0015] As a further improvement of the present invention, the transmission assembly is composed of a left pulley connected to the double-headed motor, a right pulley connected to the rotating sleeve, and a transmission belt connecting the left pulley and the right pulley. That is, the transmission belt transmits the rotational driving force of the double-headed motor to the boring tool to perform boring processing.
