The film, created as a teaching aid, introduces students to the setup and adjustment of machines on an automatic line.
Automatic production lines.
For the smooth operation of automatic machines and lines, it is important to use progressive setup and re-adjustment methods.
The simplest way to set up a machine.
A rigid stop is installed on the machine for the required processing length.
The support stops when it reaches the stop.
A cartoon explaining this operation.
Another mechanism is the stop block, which allows processing several sizes without re-adjustment.
The rotary block is adjusted to the specified length by screwing in or unscrewing the stops, and the stop is changed by turning the entire block.
Electric stop.
A cartoon explaining the action of such a stop.
A cartoon explaining the concept of the tolerance field of a part and compliance with the dimensions.
Calculation of the installation of a cutter.
A cartoon showing the calculation of the correct installation.
Making a setup standard.
The cutters are installed according to the standard.
As a result, the processed parts will be maintained in the specified dimensions without measurements and re-adjustments.
Adjustment of cutters according to a template.
On a special stand with a template, each cutter in the block is adjusted separately.
To replace a block with dull cutters, the machine only needs to be stopped for a short time.

A device for dimensional adjustment.
First, the device is adjusted, and then the cutter is installed according to the device.
A dull cutter can be replaced without additional adjustment.
Another type of adjustment.
The device is adjusted to the required size according to the standard tool, and the working cutters are adjusted according to the device.
Installing the cutter according to the device allows reducing the time for adjustment and re-adjustment, since the adjustment is performed outside the machine.
In this way, you can adjust drills, countersinks, reamers and other center tools to the required processing size.
Adjustment of multi-tool blocks used for processing bearing rings.
The countersink is installed in the block first.
And according to the adjusted device, it is adjusted to the specified processing depth.
Then the cutter is installed in the block.
In order to maintain the distance between the edges of the cutter and the countersink, another device is adjusted.
A finished block with a tool.
Another example, installing a tool for processing an engine liner.
Without stopping the machine, the cutters for chamfering the sleeve are fixed in the tool block using a template.
Then a countersink is installed in the block for processing the inner surface.
The assembled block is fixed on the machine.
Automatic device for adjusting the tool or automatic adjuster.
Cartoon explaining the operation of this device.
Device for replacing a blunt cutter with a sharpened one.
Cartoon showing the operation of the device.
The line automatically switched off, because on one of the machines the cutters went beyond the tolerance field.
A light signal on the control panel indicates the machine where the dimensions are violated.
The adjuster quickly adjusts the machine.
