Description

The invention relates to machine tools, in particular to aggregate machines with hole control devices.

The aggregate machine is known, which contains power heads placed on a frame, a separating table with clamping devices and a device for controlling openings, including monitoring and signaling units IJ.

However, in a known machine, withdrawal and approach of the control unit are carried out after processing, which increases the cycle time of the machine and reduces its productivity due to additional moves performed by the control unit. The need for additional moves is due to the fact that the probes are mounted in the plate

control device and during processing, they, together with the control plate must be removed from the treatment area to allow passage of cutting tools.

The aim of the invention is to increase the productivity of the machine.

The goal is achieved by the fact that a pusher and a cam mounted on the frame are inserted into an aggregate machine containing power heads placed on the frame, a dividing table with clamping devices and a device for controlling holes, including monitoring and signaling nodes. table in each jig and kinematically connected with the pusher, installed with the ability to interact with the copier, while the signaling nodes are placed on the frame between fishing heads.

FIG. 1 shows the proposed machine, front view; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 shows a section B-B in FIG. 2

The aggregate machine contains a bed 1, a power table 2, a spindle box 3 with cutting tools 4, a dividing table 5, a clamping device 6 with clamps 7 and 8 for clamping the workpiece 9. The devices 6 on the dividing table 6 are mounted probes W of the monitoring unit for control the presence of holes in the workpiece, which are united by a plate 11, a rolling pin 12, a lever 13 on an axis 14, a pusher 15 with a roller 16, a spring 17. The roller 16 is in contact with a cam 18 fixed fixedly outside the fixture on the body 19 of the frame 1. For Trol presence of holes in the workpiece on the machine between the power heads provided end non-contact limit switches 20, which are the signaling unit of the control device, mounted on brackets 21.

Aggregate machine in relation to the processing of clutch discs works as follows.

The workpiece 9 is mounted on the loading position I (Fig. 2) in the fixture 6 and clamped by the hooks 7 and 8. The dividing table 5 transfers the detail 9 together with the fixture 6

0 to position II where the holes are drilled. When transferring parts 9 to position III, the roller 16 slides on the copier 18, as the spring 17 all the time presses the pusher 15 to the copier. When moving the pusher 15 to the left, the lever 13 rotates on the axis 14 clockwise and moves the rolling pin 12 and the plate 11 with the probes 10 up, inserting the probes 10 into the holes drilled in position II in the workpiece 9. With holes in the part 9

0, the probes 10 pass through the part, while the limit switch 20 is turned on, signaling the presence of openings. If the drill breaks in the part 9, there will be no hole to be machined and the probe 10 will not be able to pass through the part and will

5 rests against the latter, while the pusher 15 with the roller 16 loses contact with the cam 18 and the limit switch 20 does not operate, which corresponds to a break in the drill. Thus, a marriage command will be issued and the machine is turned off.

0 The control of the presence of holes between positions III-IV and IV-I is similar. The profile of copier 18 is made such that the pusher 15 has a maximum stroke in the middle between the working positions, while providing probes 10 for the entire length of the drilled holes. At work positions, the shape of copier 18 ensures that the probes 10 are removed from the workpiece so that the probes do not interfere with the subsequent processing of the checked holes.

As a result of using the invention as compared with the known machine, the productivity of the machine is increased, since the control of the presence of the drilled holes occurs during the movement of the workpiece, therefore, the time for control is excluded from the machine cycle; technological capabilities are expanded, since a separate position or place is not required for the installation of the control device, since it is mounted in the machine tool; the machine design is simplified, since a separate drive, such as a hydraulic cylinder, is not required to move the test probes. The role of the drive is performed by the spring and the fixed

copier
