Abstract

The utility model relates to the machining equipment of the mechanical products, in particular to a lathe with a horizontal-milling head. The lathe with a horizontal-milling head is provided with a lathe body which is provided with a driving part, a spindle, a large carriage apron guide rail and a large screw mandrel. The large carriage apron guide rail is provided with a large carriage apron which is provided with a small carriage apron guide rail and a screw mandrel. The small carriage apron guide rail is provided with a small carriage apron which is provided with a horizontal-milling head. The small carriage apron is also provided with an electric motor which drives the horizontal-milling head. The driving part, one end of the big screw mandrel and one end of the small carriage apron are respectively connected with a step motor to control the rotational speed and the turning of the step motor through a digit-controlled operating system. The utility model has a novel and reasonable structure design and low manufacture cost. The horizontal-milling function is realized on the general lathe. The lathe with a horizontal-milling head can cut and process the steep-pitch thread, and the production efficiency is high.

Description

The numerical control mill-turn that crouches

Affiliated technical field

The utility model relates to a kind of engineering goods process equipment, especially a kind of lathe with horizontal-milling head.

Background technology

Engine lathe is generally by the cutter on the fixing planker, the horizontal and vertical machining that reaches the workpiece face of cylinder and end face that moves of rotation by being anchored on the workpiece on the lathe chuck and lathe tool, but such processing can not be goed deep into machining to the plane of workpiece, as reaming, fluting etc., carrying out these processing generally needs to carry out on grinding machine, when particularly cylindrical work being carried out the steep-pitch thread machining, can't finish this operation at engine lathe, adopt milling machine to add man-hour, equipment cost is higher.

Summary of the invention

In order to realize on lathe, realizing the milling machine function, particularly be to carry out screw thread processing to cylindrical workpiece, improve by part-structure engine lathe, the utility model provides a kind of numerical control mill-turn that crouches.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of numerical control mill-turn that crouches, has lathe bed, lathe bed is provided with running part, main shaft, saddle guide rail and big wire role, the saddle guide rail is provided with saddle, saddle is threaded with big wire role, saddle is provided with upper slide rest guide rail and minor leading screw, the upper slide rest guide rail is provided with upper slide rest, upper slide rest is threaded with minor leading screw, upper slide rest is provided with horizontal-milling head, on upper slide rest, also be provided with motor, motor transmission horizontal-milling head, running part, big wire role one end, upper slide rest one end is connected with stepper motor respectively.

For double thread adds the effectively control such as pitch, cutting depth and motor speed in man-hour, and realize the screw thread process automation, further: described numerical control mill-turn for sleeping in also is provided with the numerical control operating system.

For guaranteeing that more further: described running part is a reductor in workpiece workpiece smooth operation under the low speed in process.

The utility model structural design is new reasonable, and low cost of manufacture has realized crouching on engine lathe and milled function, especially can realize the machining to steep-pitch thread, the production efficiency height.

The specific embodiment

As Fig. 1, a kind of numerical control shown in Figure 2 mill-turn that crouches, has lathe bed 1, at lathe bed 1 top high order end is a stepper motor 101, stepper motor 101 rotates and drives running part 2, running part 2 has adopted reductor, make transmission more steady like this, rotate by running part 2 drive shaft 3, lathe bed 1 is provided with saddle guide rail 41, saddle guide rail 41 is provided with saddle 6, be provided with big wire role 51 in saddle guide rail 41 lower edges, lathe the place ahead, big wire role 51 is threaded with saddle 6, rotation by big wire role 51 drives saddle 6 move left and right on saddle guide rail 41, saddle 6 is provided with upper slide rest guide rail 42 and minor leading screw 52, upper slide rest guide rail 42 is provided with upper slide rest 7, minor leading screw 52 is threaded with upper slide rest 7, move rotation drive upper slide rest 7 front and back on upper slide rest guide rail 42 by minor leading screw 52, be respectively arranged with stepper motor 102 and stepper motor 103 at big wire role 51 and minor leading screw 52 1 ends, drive big wire role 51 and minor leading screw 52 rotations, the realization automation mechanized operation is over, also dispose numerical control operating system 13, numerical control operating system 13 control step motors 101, the rotating speed of control step motor 102 and control step motor 103 and turning to, thereby the rotating speed of control processing work, technological parameter such as the pitch and the depth of thread, horizontal-milling head 8 is installed on upper slide rest 7, horizontal-milling head 8 is by driving the cutting of carrying out workpiece with motor 9 belts that are installed on the upper slide rest 7, when processing work, only need to import three stepper motor service datas, just can process the whorl work piece that adheres to specification by the numerical control operating system.

Carry out steep-pitch thread and add man-hour, at first cylindric workpiece one end is fixedlyed connected with main shaft by chuck, the other end withstands in the centre hole of workpiece other end processing in advance by the tailstock thimble, it is parallel with the saddle guide rail to keep workpiece that axis is installed, with horizontal-milling head manually or be automatically moved to the initial Working position of workpiece, starter motor, driven by motor horizontal-milling head high speed rotating to three stepper motor rotating speeds and the control that turns to, starts stepper motor by numerical control operating system input relevant parameter value, by to workpiece rotational frequency, axially feed reaches the radially control of feeding speed and processes the screw thread that adheres to specification, when completion of processing, stop the running of stepper motor, withdrawing, make horizontal-milling head leave workpiece, stop motor, horizontal-milling head is shut down, unclamp chuck and thimble, take off workpiece, finish screw thread processing workpiece.
