Description

Technical Field

[0001] This utility model relates to the field of Swiss-type lathe cutter head maintenance technology, specifically to a Swiss-type lathe cutter head oil spraying device. Background Technology

[0002] The Swiss-type lathe, also known as a headstock moving CNC lathe, is a precision machining equipment. It is a high-precision CNC machine tool mainly used for machining small and complex parts. Its characteristic is that the movement trajectory of the tool and the movement trajectory of the workpiece are coordinated, which can achieve efficient machining. When the Swiss-type lathe is working, the tool head is often sprayed with oil to prevent dry wear.

[0003] Existing Swiss-type lathe cutter head oiling devices are usually fixed designs, which cannot evenly spray oil onto the cutter head. If too little oil is sprayed, some areas will not be effectively oiled and maintained, while if too much oil is sprayed, it will be wasteful. As a result, the cutter head needs to be manually brushed after each oiling to ensure that the oil is evenly sprayed, which is cumbersome and reduces the practicality of the device. Utility Model Content

[0004] The purpose of this invention is to provide an oil spraying device for the cutter head of a Swiss Army machine, in order to solve the problems of existing Swiss Army machine cutter head oil spraying devices, which are usually fixed designs and cannot evenly spray oil onto the cutter head. If the amount of oil sprayed is too small, some areas will not be effectively oiled and maintained, while if the amount of oil sprayed is too large, there will be waste. As a result, after each oil spraying, the cutter head still needs to be manually brushed to ensure the uniformity of the oil spraying, which is cumbersome to operate and reduces the practicality of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an oil spraying device for the cutter heads of a Swiss-type lathe, comprising a main body and a fixed cutter holder. A plurality of cutter head bodies are fixedly installed at the bottom of the fixed cutter holder. An oil spraying structure is provided on the outer side of the fixed cutter holder. The oil spraying structure includes an oil reservoir, which is fixedly installed on the top of the fixed cutter holder.

A connecting pipe is fixedly installed at one end of each of the connecting pipes. A nozzle is fixedly installed. Two vertical plates are fixedly installed on both sides of the fixed blade holder. A fixed plate is fixedly installed on one side of each of the two vertical plates. A reciprocating screw is rotatably installed on the bottom of each of the two fixed plates. A moving plate is threadedly connected to the outer side of each of the two reciprocating screws. A limit plate is fixedly installed on the bottom of each of the two reciprocating screws. A connecting plate is fixedly installed on the bottom of each of the two moving plates. A connecting frame is fixedly installed between the two connecting plates. The connecting frame is fixedly installed on the outer side of several corrugated hoses near the bottom. The limit plate can limit the movement of the moving plate to prevent the moving plate from moving out.

[0006] Preferably, two horizontal plates are fixedly installed on both sides of the fixed tool holder, and a connecting shaft is rotatably installed between the four horizontal plates and the four fixed plates.

[0007] Preferably, each of the four vertical plates has a sliding groove on one side, and each of the four movable plates has a limiting plate fixedly installed on one side. The four limiting plates are respectively disposed inside the four sliding grooves and slide in contact with the four vertical plates. The limiting plates disposed inside the sliding grooves of the vertical plates and slide in contact with the vertical plates can effectively limit the movable plates and prevent the movable plates from rotating together with the reciprocating screw when the reciprocating screw rotates.

[0008] Preferably, a first sprocket is fixedly installed on the outer side of each of the four connecting shafts. The four first sprockets are arranged in pairs, and a first chain is sleeved on the outer side of each pair of first sprockets.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This application uses four connecting shafts to drive four reciprocating lead screws to rotate, thereby driving four moving plates to move up and down. The four connecting plates then drive two connecting frames to move, causing several corrugated hoses to move up and down, which in turn drive several nozzles to move through several connecting pipes. This allows for uniform oil spraying on both sides of several cutter heads, effectively improving the practicality of the device. Attached Figure Description

[0021] Two horizontal plates 15 are fixedly installed on both sides of the fixed tool holder 7. Connecting shafts 16 are rotatably installed between the four horizontal plates 15 and the four fixed plates 221. One end of the four connecting shafts 16 passes through the four fixed plates 221 and is fixedly connected to the four reciprocating lead screws 17 respectively.

[0022] Each of the four vertical plates 22 has a sliding groove on one side, and each of the four movable plates 18 has a limiting plate 23 fixedly installed on one side. The four limiting plates 23 are respectively set inside the four sliding grooves and slide in contact with the four vertical plates 22 respectively.

[0023] A first sprocket 24 is fixedly installed on the outer side of each of the four connecting shafts 16. The four first sprockets 24 are in pairs, and a first chain 25 is sleeved on the outer side of each pair of first sprockets 24. The two pairs of first sprockets 24 are connected by two first chains 25 respectively.

[0024] The top of each of the two horizontal plates 15 is rotatably mounted with a second sprocket 26. A second chain 27 is sleeved on the outside of the two second sprockets 26.

[0028] During the oil spraying process, the motor 29 is started. The specific model of the motor 29 is not described here, but is based on the compatible equipment. The motor 29 drives one of the second sprockets 26 to rotate, which in turn drives another second sprocket 26 to rotate via the second chain 27. This drives two of the connecting shafts 16 to rotate, which in turn drives two of the first sprockets 24 to rotate. Then, two first chains 25 drive another two first sprockets 24 to rotate, which in turn drives another two connecting shafts 16 to rotate. The four connecting shafts 16 drive four reciprocating screws 17 to rotate, which in turn drives four moving plates 18 to move up and down. The four connecting plates 20 then drive two connecting frames 21 to move, which in turn causes several corrugated hoses 12 to move up and down. This, in turn, drives several nozzles 14 to move via several connecting pipes 13, thus uniformly spraying oil onto both sides of several cutter heads 8, effectively improving the practicality of the device.
