Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cutting tool technology, specifically a cutting tool with a self-lubricating structure. Background Technology
[0002] Cutting tools are an important type of machining tool in the field of mechanical manufacturing. They are mainly used to remove material from various metal and non-metal workpieces. Through the relative movement between the tool's cutting edge and the workpiece surface, precise control of the workpiece's shape, size, and surface quality can be achieved. These tools are widely used in many industries such as automobile manufacturing, aerospace, engineering machinery, and electronic components. Common forms include turning tools, milling cutters, drill bits, reamers, and grinding wheels. Their performance directly affects the workpiece's machining efficiency, accuracy level, and manufacturing cost, and is one of the key factors determining the level of machining technology.
[0003] During the operation of a cutting tool, the cutting edge maintains high-intensity contact and relative sliding with the workpiece surface, accompanied by intense friction and energy loss, generating a large amount of heat. This frictional and high-temperature environment directly leads to wear and breakage of the cutting edge, not only shortening the tool's service life but also reducing the workpiece's machining accuracy, resulting in surface roughness, dimensional deviations, and other problems. Therefore, lubrication and protection of the cutting tool are essential steps in machining to alleviate friction in the cutting area, reduce temperature, and ensure the stability of the machining process.
[0004] Meanwhile, a cutting tool with application number CN202222901209.8 includes a frame and a positioning device. A movable plate is slidably connected inside the frame, and a mounting frame is installed on the bottom surface of the movable plate. The positioning device is inserted into the mounting frame, and a cutting tool is installed on the positioning device. A threaded cylinder is rotatably connected to the inner top surface of the frame, and a threaded rod is threadedly connected inside the threaded cylinder. The lower end of the threaded rod is fixedly connected to the movable plate, and a drive mechanism for driving the threaded cylinder to rotate is provided on the frame.
[0005] However, the following problems were found in the implementation of the relevant technologies: traditional external lubrication designs require a large amount of lubricating oil, which will pollute the environment if not recycled properly, and the volatile oil mist will also harm the health of operators. A cutting tool does not mention self-lubrication during cutting, which causes the cutting edge of the tool to always maintain high-intensity contact and relative sliding with the workpiece surface during the working process. This not only shortens the service life of the tool, but also reduces the machining accuracy of the workpiece, resulting in problems such as surface roughness and dimensional deviation. Utility Model Content
[0006] To address the problems mentioned in the background section, this invention provides a cutting tool with a self-lubricating structure, which has the advantages of reducing lubricant waste and providing self-lubrication for the cutting tool.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a cutting tool with a self-lubricating structure, comprising a machining base, on which a transmission assembly and a lubrication assembly are respectively provided. A first drive source is connected to the top of the machining base, and a lubrication cylinder is poweredly connected to the power output end of the first drive source. An oil inlet is provided on the surface of the lubrication cylinder, and a guide bucket is connected to the bottom of the lubrication cylinder. A cutting tool body is connected to the bottom of the guide bucket, and a plurality of lubrication holes are provided on the surface of the guide bucket. An oil storage tank is connected to the top of the machining base, and a support plate is connected to the surface of the machining base. A second drive source is connected to the inner side of the support plate.
[0008] The surface of the transmission component is electrically connected to the power output end of the second drive source to drive the transmission component to perform intermittent transmission.
[0009] The surface of the lubrication component is poweredly connected to the power output end of the transmission component to drive the lubrication component to adjust its height in the vertical direction.
[0010] Preferably, the transmission assembly includes a half gear, a connecting rod, and a limiting rod. The half gear is disposed on the power output end of the second drive source. The connecting rod is disposed at the bottom end of the support plate. A transmission gear is rotatably connected to the bottom end of the connecting rod. A connecting screw is connected to the bottom end of the transmission gear. A connecting plate is threadedly connected to the surface of the connecting screw through a screw nut. The limiting rod is disposed at the top end of the processing seat.
[0011] Preferably, the half gear is meshed with the transmission gear.
[0012] Preferably, the surface of the limiting rod is slidably connected to the inner side of the connecting plate.
[0013] Preferably, the lubrication assembly includes a hose and a solenoid valve. The hose is disposed on the surface of the oil reservoir, one end of the hose is connected to a rigid pipe, and the solenoid valve is disposed on the surface of the hose.
[0014] Preferably, the inner side of the connecting plate is connected to the surface of the rigid tube.
[0015] Preferably, one end of the rigid pipe is connected to the oil inlet.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] This invention utilizes the shape characteristics of a half-gear to drive a transmission gear for intermittent transmission, facilitating vertical adjustment of the rigid tube opening. Furthermore, by driving the half-gear in both directions, the connecting screw can rotate in both directions, and the rigid tube opening can be displaced at a fixed distance. The rigid tube, corresponding to the oil inlet, facilitates the flow of lubricating oil through multiple lubrication holes to the surface of the cutting tool body. Combined with a solenoid valve, this enables self-lubrication of the cutting tool body, avoiding the waste caused by indiscriminate spraying and continuous oil supply of traditional lubricating oil. This allows the lubricating oil to be precisely applied to the friction area of the cutting tool body, thus improving the utilization efficiency of the lubricating oil. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] like Figures 1 to 7 As shown, this utility model provides a cutting tool with a self-lubricating structure, including a machining base 1, on which a transmission component 2 and a lubrication component 3 are respectively provided. The top of the machining base 1 is connected to a first drive source 4, and the power output end of the first drive source 4 is connected to a lubrication cylinder 5. The surface of the lubrication cylinder 5 is provided with an oil inlet to form a lubricating oil input channel, which facilitates smooth and unobstructed oil supply. The bottom end of the lubrication cylinder 5 is connected to a guide bucket 6, and the bottom end of the guide bucket 6 is connected to the cutting tool body 7. The surface of the guide bucket 6 is provided with a plurality of lubrication holes 8, which helps to improve the uniformity of lubrication. The top of the machining base 1 is connected to an oil storage tank 9, and the surface of the machining base 1 is connected to a support plate 10. The inner side of the support plate 10 is connected to a second drive source 11.
[0031] The surface of the transmission assembly 2 is poweredly connected to the power output end of the second drive source 11 to drive the transmission assembly 2 to perform intermittent transmission.
[0032] The surface of the lubrication component 3 is poweredly connected to the power output end of the transmission component 2 to drive the lubrication component 3 to adjust its height in the vertical direction.
[0033] Specifically, the transmission assembly 2 includes a half gear 21, a connecting rod 22, and a limiting rod 26. The half gear 21 is located on the power output end of the second drive source 11. The connecting rod 22 is located at the bottom end of the support plate 10, which facilitates providing a stable mounting point for the transmission gear 23. The bottom end of the connecting rod 22 is rotatably connected to the transmission gear 23. The bottom end of the transmission gear 23 is connected to the connecting screw 24. The surface of the connecting screw 24 is threadedly connected to the connecting plate 25 through the screw nut. The threaded transmission has high precision characteristics, which facilitates the control of the lifting height of the connecting plate 25. The limiting rod 26 is located at the top of the machining base 1, which facilitates the guiding and limiting function of the connecting plate 25, so that the lifting action is smooth.
[0034] Furthermore, the half gear 21 meshes with the transmission gear 23, which facilitates the intermittent rotation of the transmission gear 23.
[0035] Furthermore, the surface of the limiting rod 26 is slidably connected to the inner side of the connecting plate 25, which facilitates the improvement of the stability of the connecting plate 25 as it rises and falls in the vertical direction.
[0036] It is worth noting that the lubrication component 3 includes a hose 31 and a solenoid valve 33. The hose 31 is set on the surface of the oil reservoir 9. The hose 31 is flexible and can be adapted to the lifting and lowering of the rigid pipe 32 to avoid damage. One end of the hose 31 is connected to the rigid pipe 32. The solenoid valve 33 is set on the surface of the hose 31. The solenoid valve 33 can be used to control the oil circuit opening and closing.
[0037] It is worth noting that the inner side of the connecting plate 25 is connected to the surface of the rigid tube 32, which facilitates the synchronous lifting and lowering of the rigid tube 32 and the connecting plate 25.
[0038] It is worth mentioning that one end of the rigid pipe 32 is connected to the oil inlet, which facilitates the stable delivery of lubricating oil.
[0039] Among them, the solenoid valve 33 is prior art and will not be described in detail; at the same time, this utility model also includes a power supply, a controller, and a switch, etc., which are not the main technical points of this patent and will not be described in detail; the "front, back, left, and right" perspectives of this device are as follows: Figure 1 The direction shown in the diagram is the reference.
[0040] Working principle: First, before the first drive source 4 drives the cutting tool body 7 to operate, the second drive source 11 drives the half gear 21 to rotate. The shape characteristics of the half gear 21 drive the transmission gear 23 to perform intermittent transmission. At this time, the connecting screw 24 is driven to rotate intermittently. Assuming that the connecting screw 24 rotates forward at this time, the connecting plate 25 will drive the hard tube 32 to move down until the surface of the half gear 21 without the rack contacts the connecting screw 24. At this time, the hard tube 32 is exactly in contact with the oil inlet on the surface of the lubrication cylinder 5. Then, the second drive source 11 is turned off, and the solenoid valve 33 is activated so that the lubricating oil in the oil storage tank 9 enters the interior of the lubrication cylinder 5 through the hose 31 and the hard tube 32, and drips onto the surface of the cutting tool body 7 through the guide bucket 6 and the lubrication hole 8, realizing the self-lubrication operation of the cutting tool body 7.
[0041] After the above steps are completed, the second drive source 11 drives the half gear 21 to reverse its direction compared to before, which drives the connecting plate 25 and the hard tube 32 to reset and move upward, so that the hard tube 32 is separated from the oil inlet. The surface of the lubrication cylinder 5 is provided with a groove to prevent the hard tube 32 from continuously contacting the surface of the lubrication cylinder 5 when it moves upward, so as not to affect the high-speed rotation of the lubrication cylinder 5 and the cutting tool body 7 driven by the first drive source 4. Through the continuous forward and reverse rotation of the half gear 21, the lubrication cycle is repeated continuously, realizing the periodic self-lubrication of the cutting tool body 7, which helps to ensure the stable operation of the cutting operation.
