Problems solved by technology
[0002]At present, most of the known deep hole processing equipment are independent equipment for boring, drilling, drawing and grinding. In many cases, it cannot well meet the needs of deep hole processing
As far as deep hole processing is concerned, the main reason affecting its work efficiency and geometric accuracy is that after processing the deep hole, it has to be moved to a broaching machine or a grinding machine for secondary alignment before processing. It is difficult to return to the original position after the first processing when the deep hole processing parts are aligned for the second time, which directly affects the geometric accuracy of the back processing and affects the work efficiency at the same time

The invention discloses deep hole processing equipment capable of realizing boring, drilling, pulling and milling on one piece of equipment. Front and back two groups of worm and gear mechanisms are adopted, and a spiral combination and axial sliding fit together with a screw rod shaft provided with a guide groove is constructed through a nut and a guide sliding key at the central position of a worm wheel respectively; an inner sleeve, a guide sleeve and a guide sliding key are arranged in a front worm wheel inner hole; a guide sliding key is in sliding fit with the guide groove on the screw rod shaft; an inner sleeve, a connecting sleeve and a nut are arranged in a back worm wheel inner hole; and the nut and the screw rod shaft form a spiral combination. Advancing, retreating, rotation, positioning and indexing of the screw rod shaft are realized through relative movement from stillness to low speed to high speed rotation and mutual action of the two groups of worm and gear mechanisms. A connecting shaft head at the front end of the screw rod shaft is used for installing boring, drilling, pulling and milling mechanisms. During processing of super long deep hole workpieces, the screw rod shaft can be lengthened in a butt joint way by connecting a preserved hole with the tail end of the screw rod shaft.
Description
1. Technical field [0001] The invention relates to a device capable of multifunctional processing of deep hole boring, drilling, drawing and grinding, which belongs to the field of mechanical manufacturing. 2. Background technology [0002] At present, most of the known deep hole processing equipment are independent equipment for boring, drilling, drawing and grinding. Although the existing boring machines have the capability of boring and drilling, in many cases, they cannot well meet the needs of deep hole processing. As far as deep hole processing is concerned, the main reason affecting its work efficiency and geometric accuracy is that after processing the deep hole, it has to be moved to a broaching machine or a grinding machine for secondary alignment before processing. It is difficult to return to the original position after the first processing when the deep hole processing parts are aligned for the second time, which directly affects the geometric accuracy of the ba...
