Problems solved by technology

In the above-mentioned boring and milling head, the speed change of the transmission spline shaft is realized by the movement of the sliding pinion driven by the manual control mechanism. The disadvantages of using the manual control mechanism are: the complexity of the equipment increases, and the speed change control is not convenient enough
In addition, in the existing boring and milling head of this kind, the square ram feeding mechanism and the boring shaft feeding mechanism share one motor, and a transmission and clutch mechanism need to be added between the two feeding mechanisms, and the resulting disadvantages Yes: the complexity of the equipment increases, and the transmission chain of the equipment increases

Embodiment Construction

[0009] The present invention is further described below in conjunction with embodiment and accompanying drawing.

[0010] see figure 1 , figure 2

[0011] The basic structure of the boring and milling head provided by the present invention is the same as that of the prior art. A square ram 12 is installed in the box body 1. A square ram feeding mechanism is installed between the square ram 12 and the box body. The boring shaft 15 is mounted on a square ram. Inside the ram 12, the milling shaft 16 is installed on the boring shaft 15, the boring shaft feeding mechanism is installed between the boring shaft 15 and the square ram 12, the driving gear shaft 2, the intermediate shaft 6, and the transmission spline are installed in the box body 1 Shaft 9, driving gear shaft 2 is connected with main motor 5, transmission spline shaft 9 and milling shaft 16 are connected with transmission mechanism, intermediate shaft 6 is equipped with large gear 3 and pinion 4, and large gear 3 me...

Abstract

The invention relates to a boring and milling head. A square ram is arranged in a box body; a square ram feeding mechanism is arranged between the box body and the square ram; a boring shaft is arranged in the square ram; a boring shaft feeding mechanism is arranged between the boring shaft and the square ram; a driving gear shaft, an intermediate shaft and a transmission spline shaft are arranged in the box body; a big gear and a pinion are arranged on the intermediate shaft; the big gear is meshed with the driving gear shaft; a sliding pinion on the transmission spline shaft is connected with a sliding big gear; the rear end of the square ram is connected with a feeding box; a shifting fork is arranged on the sliding pinion; a cylinder is arranged on the box body; the shifting fork is connected with a piston rod of the cylinder; and a first feeding screw rod of the boring shaft feeding mechanism and a second feeding screw rod of the square ram are connected with a motor respectively. The cylinder is controlled to move the shifting fork, so transformation between cooperation of the sliding pinion and the sliding big gear and cooperation of the big gear and the pinion can be realized and speed variation of the transmission spline shaft can be realized. The two feeding screw rods are connected with the motor respectively, so the two feeding screw rods can be controlled respectively and the equipment structure is simplified.

Description

technical field [0001] The invention relates to a machining machine tool, in particular to a boring and milling head for a boring and milling machine. Background technique [0002] The basic structure of the existing boring and milling head in a boring and milling machine is that a square ram is installed in the box, a square ram feeding mechanism is installed between the square ram and the box, the boring shaft is installed in the square ram, and the milling shaft is installed. On the boring shaft, a boring shaft feeding mechanism is installed between the boring shaft and the square ram. The drive gear shaft, intermediate shaft, and transmission spline shaft are installed in the box. The drive gear shaft is connected with the main motor, and the transmission spline shaft is connected to the A transmission mechanism is connected between the milling shafts, a bull gear and a pinion are arranged on the intermediate shaft, and a slip bull gear is connected on the slip pinion ar...
