Description
Technical Field
[0001] The utility model relates to the technical field of machine tool design, in particular to a rigid sealing strip for preventing liquid seepage in a numerically controlled lathe. Background Art
[0002] With the rapid development of modern manufacturing, the requirements for machining accuracy and efficiency are constantly increasing. As one of the important equipment for precision machining, CNC lathes are widely used in aviation, aerospace, automobile manufacturing, mold processing and other fields. During high-speed cutting, the friction between the tool and the workpiece will generate a large amount of iron chips and high temperature. Therefore, cutting fluid is used in the cutting process. These cutting fluids can not only remove heat and iron chips from the cutting area, reduce tool wear and improve machining quality, but also lubricate the cutting area to prevent chips from sticking.
[0003] However, traditional CNC lathes often ignore the sealing problem of cutting fluid in their design, which causes the cutting fluid to easily penetrate into other parts of the machine tool during use, causing corrosion, contamination and damage to machine tool components, and also poses a threat to the safety of operators. In addition, the leakage of cutting fluid will also increase production costs because it needs to be replaced and replenished regularly. Utility Model Content
[0004] In response to the above technical problems, this utility proposes the following technical solutions:
[0005] A rigid sealing strip for preventing liquid seepage in a CNC lathe comprises a machine tool base, a machine tool shell being fixedly mounted on the machine tool base, a side panel being fixedly mounted on one side of the machine tool shell, a fixing column being fixedly mounted on the side panel, the fixing column being fixedly mounted in the machine tool shell, a guide plate being fixedly mounted on one side of the fixing column, a groove being provided on the side of the fixing column, a sealing strip being provided on the side of the fixing column, the sealing strip being embedded in the groove of the fixing column during installation, the sealing strip being fitted with the guide plate, and being used to remove iron slag on the surface of the guide plate during use, a sealing rubber strip being provided in the sealing strip, the sealing rubber strip being a sealing component, being in close contact with the guide plate, and being able to remove liquid on the surface of the guide plate when the guide plate slides.

DETAILED DESCRIPTION
[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0021] like Figure 1 and Figure 2 As shown, a rigid sealing strip for preventing liquid seepage in a CNC lathe comprises a machine tool base 101, on which a machine tool casing 102 is fixedly mounted, and on which a machine tool guide rail 104 is also fixedly mounted, and the machine tool guide rail 104 is fixedly mounted in the machine tool casing 102, and on which a tool holder 103 is slidably mounted, and a side fence 105 is fixedly mounted in a side of the machine tool casing 102 away from the tool holder 103, and on which a fixed column 203 is fixedly mounted, and the fixed column 203 is fixedly mounted in the machine tool casing 102, and on one side of the fixed column 203 a guide plate 201 is fixedly mounted, and a right angle is formed between the guide plate 201 and the side fence 105, and a sliding plate 202 is slidably mounted in a stepped manner on the end of the guide plate 201 away from the fixed column 203, and the guide plate 201 and the sliding plate 202 form a closed slide.
[0022] like Figures 2 to 4 and Figures 6 to 8 As shown, a groove is provided on the side of the fixing column 203, and a sealing strip 211 is provided on the side of the fixing column 203. The sealing strip 211 is made of high manganese steel. The sealing strip 211 is embedded in the groove of the fixing column 203 during installation. A fixing plate 213 is fixedly installed on the sealing strip 211, and a plurality of fixing bolts 214 are provided on it. The fixing bolts 214 are connected to the fixing column 203 through threads. The sealing strip 211 fits the guide plate 201. When in use, the sealing strip 211 is used to remove iron slag on the surface of the guide plate 201. A sealing rubber strip 212 is provided in the sealing strip 211. The sealing rubber strip 212 is a sealing component. The sealing rubber strip 212 is in close contact with the guide plate 201. When the guide plate 201 slides, the sealing rubber strip 212 can remove liquid on the surface of the guide plate 201.
[0023] like Figures 2 to 8 As shown, a cleaning motor 204 is fixedly mounted on the side fence 105, and a guide wheel 206 is fixedly mounted on the output shaft of the cleaning motor 204. A conveying belt 207 is provided on the guide wheel 206, and the conveying belt 207 is slidably connected to the side fence 105. A fixed cylinder 208 is fixedly mounted on the conveying belt 207, and a cleaner 210 is rotatably mounted on the output shaft of the fixed cylinder 208. A plurality of iron brushes are provided on the cleaner 210, and the iron brushes are used to clean iron filings between the sealing strip 211 and the guide plate 201. A track frame 205 is also fixedly mounted on the side fence 105, and a passive rack is provided on the inner side of the track frame 205, and the passive rack is meshed with a passive gear 209. When the conveying belt 207 moves with the fixed cylinder 208, the passive gear 209 will mesh with the passive rack, thereby allowing the cleaner 210 to rotate.
[0024] Working principle: When this device is used to improve the original machine tool, it is only necessary to replace the side fence 105, the fixed column 203, and the guard plate at the guide plate 201, first set the sealing rubber strip 212 in the sealing strip 211, then fit the sealing strip 211 to the surface of the guide plate 201, and at the same time embed the sealing strip 211 into the groove of the fixed column 203, and then use the fixing bolt 214 to fix the fixing plate 213 and the sealing strip 211, and then install the cleaning motor 204, the conveyor belt 207, and the cleaner 210. During installation, it should be noted that the brush on the cleaner 210 needs to be in contact with the guide plate 201 and the sealing strip 211.
[0025] When the device is in use, with the appearance of cutting fluid and iron chips and the movement of the tool holder 103, the guide plate 201 and the sliding plate 202 will shrink and fold. When the guide plate 201 slides on the fixed column 203, the sealing strip 211 will remove all the iron chips and most of the cutting fluid on the surface of the guide plate 201, and a small amount of cutting fluid will be blocked by the sealing rubber strip 212, thus preventing the cutting fluid from leaking. The blocked cutting fluid will rush along the guide plate 201 to the bottom of the guide plate 201 and then enter the machine tool base 101 for circulation. In batch processing, the cleaning motor 204 can be started regularly. The cleaning motor 204 drives the conveyor belt 207 to work through the guide wheel 206, and the conveyor belt 207 drives the cleaner 210 to move toward the machine tool base 101 when working. Then, when the cleaner 210 moves, since the passive gear 209 is engaged with the track frame 205, the passive gear 209 and the cleaner 210 will rotate, and the cleaner 210 will also rotate when moving toward the machine tool base 101. Then, the cleaner 210 will clean the iron filings at the gap between the guide plate 201 and the sealing strip 211, and the movement of the cleaner 210 will also accelerate the movement of the iron filings. The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
