Description

Oil film measuring device of processing machine feed system

The present invention is related to the oil film measurement structure of the feed system of a processing machine, and particularly refers to an oil film measurement device of the feed system of a processing machine that can accurately determine the timing of oil injection.

In order for the processing machine to maintain good processing efficiency, the processing machine must provide good lubrication in all parts of the sliding or rolling. The conventional processing machine usually uses an oil injection machine to connect to the lubrication oil injection point through a pipeline, and is controlled by a programmable logic Programmable Logic Controller (PLC) is programmed to control the oil supply of the lubricating machine, so as to provide lubricating oil to the lubricating oiling point to achieve a lubricating effect. The timing of the above-mentioned lubricating machine supplying oil to the lubricating oil injection point can be determined by measuring the oil film thickness, that is, measuring the oil film thickness with a measuring instrument. If the oil film thickness of a certain lubricating oil injection point is lower than the standard value, a signal is generated and feedback To the aforementioned programmable logic controller to control the oil supply of the oil injection machine.

For example, the oil film measuring device provided by my country's Patent No. I635925 mainly uses a roller to slide and contact the slide rail of the feed system, when the roller slides on the slide rail with the slide table of the feed system When the thickness of the oil film on the slide rail is different, the change in the rotation speed of the drum can be measured by its rotation speed detector and converted into the thickness of the oil film by a control unit. When the thickness of the oil film is lower than the standard value When the time, the oil injection unit is controlled to supply oil to the lubricating oil injection point. However, this contact-type oil film thickness measurement method is not only susceptible to uneven oil film thickness on the slide rail, but also seriously affects its measurement accuracy. Also, because the speed detector is located outside, it will also be easy The problem of measurement error or damage caused by collision. In addition, when the roller is slid on the slide rail of the feed system in a contact manner, due to the relatively large volume of the roller, an assembly space must be reserved on the feed system for installation.

The circuit fixing board 31 is made of a light-permeable material (for example, transparent acrylic material) in a plate shape with a certain thickness, and is relatively accommodated in the accommodating space 221, and the circuit fixing board 31 is provided with a container. A groove 32, and a convex portion 33 protruding along the inner edge of the receiving groove 32 is formed. The convex portion 33 defines an oil groove 34 extending in the vertical direction and penetrating the circuit fixing plate 31, and a circuit board 35 accommodates In the container 32, the circuit board 35 is electrically connected with a control unit 36, a light source transmitter 37 and a light source receiver 38. Wherein, the control unit 36 is composed of a single-chip microcontroller for receiving and transmitting control signals, and when the circuit board 35 is accommodated in the container 32, the light source transmitter 37 and the light source receive The receivers 38 are respectively located on two opposite sides of the oil tank 34, and are located at the same horizontal height position and arranged at relative intervals, and can be determined according to whether the light source receiver 38 has received the light source signal emitted by the light source transmitter 37 (for example, Infrared light) to detect the amount of oil in the oil tank 34, so that the control unit 36 can relatively control the oil filling action of an oil filling unit (not shown in the figure). Furthermore, the seat body 21 is provided with a pressure relief hole 26 communicating with the oil groove 34 at a position opposite to the oil groove 34, so that the oil groove 34 can communicate with the outside through the pressure relief hole 26, and the seat body 21 A wire hole 27 communicating with the containing slot 32 is additionally opened at a position opposite to the containing slot 32, so that related wires (not shown in the figure) on the circuit board 35 can pass through the wire hole 27. .

In practical use of the present invention composed of the above structure, when the oil film measuring device 20 slides with the carrier 12, the lubricating oil on the slide rail 111 will continue to be affected by the oil guide plate 41. By pushing, the lubricating oil can be gradually poured into the oil groove 34 along the oil guide groove 43 and through the oil guide hole 42. Therefore, if the thickness of the lubricating oil film on the slide rail is insufficient, the lubricating oil in the oil groove 34 cannot be reduced. The liquid level rises effectively. That is, when the level of the lubricating oil collected in the oil groove 34 has not risen to the level that can block the light source signal emitted by the light source transmitter 37, it means that the amount of oil film on the slide rail 111 is insufficient. At this time, the processing machine The oil injection unit of the feed system will continue to supply lubricating oil to the slide rail 111; on the contrary, as shown in Figure 6, when the level of lubricating oil in the oil tank 34 rises to a level that can relatively block the light emitted by the light emitter 37 When the light source signal is displayed, it means that the amount of oil film on the slide rail 111 is appropriate.
