Vertical multi-purpose machine

boring-milling-boring

with a cross table, with ChPU, with ASI.

The utility model relates to mechanical engineering and can be used for positional and contour processing of parts such as flange, cover, housing, etc., as well as for processing shaped surfaces that require tool movement simultaneously in 3 coordinates.

The previously known CNC machine did not fully satisfy the customer's requirements for a number of technical characteristics: rigidity, productivity. The maximum spindle speed of this machine is up to 6000 revolutions per minute. Tool change time - 16 seconds, ff

The purpose of creating a utility model is to expand technological capabilities and increase productivity in the processing of various materials by operations of milling, drilling, boring.

The vertical boring-milling machine of the cantilever type, with a cross table and with the movement of the headstock allows processing simultaneously in three coordinates.

Cast body parts are made with sufficient rigidity, which ensures high precision machining. The guides of the machine are hardened, and the counterparts are coated with antifriction material.

s -. ;

which provides good glide, reducing friction losses. DC drives provide infinitely variable feed control in all coordinates. The machine uses centralized impulse lubrication of the guides, controlled by the CNC of the machine.

The machine has the following coordinates:

1. X axis - continuous movement of the table

2. Y axis - lateral movement of the table

3. Axis Z - vertical movement of the headstock

According to customer requirements, the machine can be manufactured in several versions: from a universal milling machine with a 10-speed gearbox and manual control of feed drives to a machine with programmed control with stepless adjustment of the spindle speed (up to 8000 rpm) and automatic tool change . Automatic tool change allows you to change the tool in the spindle during machining in 2.5 seconds or 7.5 seconds, depending on the execution of the tool magazine and the required performance. Also, the machine can be equipped with a cabinet-type cutting area guard. Everything

the above allows you to satisfy any customer requirements.

The mechanical base of the machine consists of fixed parts - base 1 and column 2. On the base mounted slide 3; which can be moved along the base (Y coordinate) through the transmission of a rolling screw-nut, which is connected through the coupling to the motor. Along the slide 3, the table 4 moves (X coordinate) by means of a transmission screw-nut rolling, which also connects through the coupling with its engine.

A part or fixture with a part is installed on the table. On column 2, a spindle head 5 is mounted, moving up and down (coordinate Z) by means of a transmission screw-nut rolling, which is also connected through the coupling with its engine. A spindle 6 is installed in the headstock, rotating through a belt or gears (depending on version) by an electric motor 7. A bracket 8 is attached to the column 2, on which, in turn, the tool magazine 9 is attached with a tool change time of 7.5 seconds or the tool magazine with a change time tool 2.5 seconds, depending on customer requirements. All electric motors are controlled by the CNC machine according to a given program, independently of each other.

The machine operates as follows.

The workpiece is mounted on the table 5 and clamped with tacks. The operator turns on the CNC system, and the work cycle begins. The tool is installed in the spindle cone manually or automatically (if there is a tool magazine). The electric motor 7 rotates the spindle with the tool with a given speed and performs the processing of the part. The movement of the tool feeds relative to the part along the coordinates X, Y, Z is carried out by moving the corresponding machine nodes with their drive mechanisms. Coordinate drives are independently controlled by the CNC system. friend. After the execution of the specified program, the tool is retracted from the part, and the cycle of processing one part is completed. Head of the petition department Authors I.
