Abstract

The invention relates to foundry and can be used for stripping castings. The purpose of the invention is to increase labor productivity by simplifying the control systems for moving the working tool with a given cutting force. The device consists of a rotating engine platform on which a shoulder with a manipulator arm is mounted. The tool is mounted on the traverse with the possibility of rotation around the vertical axis and reciprocating movement in two mutually perpendicular directions. Traverse mounted on the axle on one side and the hydraulic motor rotor - on the other. 1 hp ff, 10 ill.

Description

The invention relates to foundry and can be used for cutting and stripping large-sized castings of complex shapes.

The aim of the invention is to increase labor productivity by simplifying the control system for moving the working tool with a predetermined cutting force

Figure 1 shows the installation, General view; figure 2 is the same section; on Fig - section aa in figure 1; figure 4 - view B in fig.Z; figure 5 - section bb In fig.Z; Fig 6 - section GGD fig.Z; figure 7 - section dD in figure 6; on fig.Z - section EE of figure 6; Fig. 9 shows a section of an Ж-Ж in Fig.6; figure 10 - section 3-3 in figure 9.

The installation consists of a platform 1 of a rotary engine 2, shoulder 3,

arms 4 and working cylinders 5 and 6, which respectively affect the raising and lowering of the shoulder 3 and the movement of the arm 4о. The hinged manipulator mechanism provides the vertical position of the axis 7 during any movement of the shoulder 3 and the arm 4. On the axis 7, the suspension 8 is installed, which can rotate at an incomplete angle with the help of a rotating hydraulic motor consisting of a housing 9, a rotor 10, a cavity separator 11 and a cover 12e. Flexible sleeves 13 are brought to housing 9. The rotor 10 is connected to the axis 7 through the gauge 14, and the housing 9 is fixedly connected to body 15 p 8 “At the same time, the housing hangs on the axis 7 along the sleeve 16 and is fixed with a nut 17. Two sides 19 are attached to the housing 15 on screws 18,

On the sides 19, two pads 20 with guide grooves adjoin its inner torsons. In the lower part of the carpets 19 there are two coaxial holes, - one of which includes a pin 1e and the other - a rotor 22 of a rotary idromotor 23, the device of which similar to the specified. The rotor 22 is connected to the sidewall 19 along the cylindrical surface, and with the pad 20 along the slots. In this way, as the rotor 22 rotates, the pads 20 can be rotated. By directing the pads 20, the yoke 249 15 can be moved in which the machining tool 25 is installed, fixed by screws 26. The yoke 24 is under the action of four springs 27, which are placed in the sleeves 28, 20 in the upper covers 29, the lower covers 30 hold the yoke 24 in the lower position. The springs 27 abut against the screws 31. Under the action of the springs 27 of the yoke 24 with the tool 25, the lower position is worn. To feed the hydraulic motors, rigid and flexible pipes 32, 33, 13, 34 and pads 35 o are installed.

The installation works as follows

A tool 25, for example a standardized chipping hammer, is installed in the yoke 24 of the suspension 8 and fixed with screws 26,

The tool 25 can make a circular motion about the vertical axis of the platform 1, and make reciprocating movement 4 () along the same axis and perpendicular to it. Suspension 8 can rotate about the axis 79 and the yoke 24 together with the tool 25 turn on the trunnion 21 and rotor 22. d

The operator from the control panel (not shown) controls the movement of the tool 25 relative to the casting, bringing it at the required angle to the machining site. Supply the chisel of the tool 5d 25, the operator turns on the chi35

Lindles 5 and 6 for chisel insertion, after which the compressed air is supplied to the tool 25

After processing one part of the casting, tool 25 is retracted from it and brought to another.

After processing all parts of the casting, it is removed and a friend is installed in its place,

Using the device simplifies tool management, which improves productivity.
