This controller is much more accurate and trouble-saving than manual control by the human eye, and i have now used this controller. The automatic controller is composed of a switch control circuit and simple peripheral electrical elements, is suitable for all places needing accurate control and automatic shutdown without accurate control, has the advantages of low cost, accuracy, safety and convenience in use because a person can watch a plurality of machine tools, and is expected to bring production and life benefits to people needing the controller.)

1. The dial indicator or the digital display dial indicator is additionally provided with an adjustable dial indicator or a digital display dial indicator reading accurate control device which is composed of a support screw butterfly nut and two line connecting contact magnets, and a limit circuit which is composed of a flat opening switch magnet.

The technical field is as follows:

the invention relates to a simple, safe and accurate automatic controller for a machine tool.

Background art:

the invention relates to a simple, safe and accurate automatic controller for a lathe, which is invented by continuous thinking and reference, wherein the size is measured by frequent stopping when the lathe is operated at ordinary times, and the accident danger is generated when a turning tool supporting plate is carelessly moved to excessively touch a rotating chuck sometimes. This controller is much more accurate and trouble-saving than manual control by the human eye, and i have now used this controller.

The invention content is as follows:

the invention is a simple, safe and accurate automatic controller of a machine tool, namely a purchased switch control circuit board 22 is used, a bracket 10 is added to a dial indicator 9, a 1 cm-wide stainless steel plate winds the dial indicator, 18 screws pass through 16 through holes 19 nuts to be fixed on the dial indicator, 11 the 1 cm-wide stainless steel plate is folded into a door-shaped hook to clamp a knob at the other end of the dial indicator, 15 screws pass through the door-shaped stainless steel plate, are fixed by 14 nuts and then pass through the bracket stainless steel plate through holes 23, and are loosened and screwed by 13 butterfly nuts, so that the reading of the dial indicator can be adjusted, 17 contacts are sleeved on a contact head of the dial indicator and need to be insulated, 1 is attached with a small copper circuit board, a galvanized iron plate is adhered to the back surface of the small copper circuit board, the magnet is convenient to adsorb, and an electric wire connection point; 2 is a controller consisting of a 12v direct current power supply, a power plug 6, a machine tool motor socket 4, a light-emitting tube 7 and a flat switch 5; the plug 6 inserts the power, 5 erect spacing flat switch, can establish ties a plurality of constitution multiple spot spacing, through gluing on magnet and fixing to the track needs department, touch and open, 4 socket outage, control machine tool switch plays limiting displacement, 7 luminotrons show the state of 5 switches, 8 key press circuit 12 relay actuation 3 luminotrons are luminous, the machine tool circular telegram, 8 key 12 relay release is pressed once more, 3 luminotrons go out, the machine tool outage, 3 show the on-off state of relay, 1, 17 external two line connection contacts of percentage table are low-voltage and main power source keep apart, it is safe, be equivalent to 8 buttons, glue respectively on two magnet, connect the contact of percentage table to the place that the relative movement of machine tool needs the accurate measurement, in order to reach accurate automatic control's purpose. For example, a contact piece 1 attracted on a magnet is fixed on a fixed guide rail of a machine tool, a contact 17 of a dial indicator attracted with the magnet is fixed on a movable guide rail of the machine tool, the contact piece of the dial indicator contacts, the reading of the dial indicator reaches the required stroke, such as 5.08mm, a main switch of the machine tool is opened, an 8-key is pressed, a relay is attracted, the machine tool is started, the contact piece of the dial indicator contacts again, a 12-relay is released, the machine tool is stopped, and the purpose of accurate and automatic control is achieved, so that the simple, safe and accurate automatic controller of the machine tool is formed; the 12 relay can control the electromagnetic relay to control the more powerful motor, can use another switch of relay more to use, 21 is the socket that has earth-leakage protector, plays earth-leakage protection's effect, is applicable to all needs accurate control and does not need the place of accurate control auto-stop, has and just can watch several lathes alone, and is with low costs, accurate safe automatic convenient to use's advantage, hopes that this controller brings the welfare of production life for the people of needs.

The attached drawings are as follows:

The specific implementation mode is as follows:

the invention relates to a simple, safe and accurate automatic controller for a machine tool, which is formed by assembling a switch control circuit and various electric devices together through peripheral elements by using a galvanized sheet box and adding an adjustable dial indicator or an accurate control device for digital display dial indicator reading, wherein the adjustable dial indicator or the accurate control device is formed by a support screw butterfly nut and two line connection contact magnets.
