Description

Technical Field

[0001] The utility model relates to the technical field of slide rail structures, in particular to a slide rail structure of a simple turning and milling CNC lathe. Background Art

[0002] CNC lathes are one of the most widely used CNC machine tools. They are primarily used for machining internal and external cylindrical surfaces of shafts and discs, internal and external conical surfaces of arbitrary taper angles, complex internal and external rotational curved surfaces, and cylindrical and conical threads. They can also perform grooving, drilling, reaming, reaming, and boring.

[0003] In the use of existing lathes, when the tailstock slides on the slide rail, there are friction and other effects, but there are certain shortcomings in the lubrication of the slide rail. For example, when lubricating the slide rail, the lubricating oil consumed by the number of times the tailstock slides is not well controlled, and sometimes lubrication is forgotten. The tailstock is blocked when sliding on the slide rail, which is not conducive to the lubrication between the tailstock and the slide rail. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a slide rail structure for a simple turning and milling CNC lathe, which has the advantages of extrusion lubrication and lubricating oil sealing, and solves the problems raised by the above-mentioned background technology.

[0005] The utility model provides the following technical solutions: a slide rail structure of a simple turning and milling CNC lathe, comprising a bed, a spindle box fixedly installed on one side of the bed, a limit plate fixedly installed on one side of the spindle box located above the bed, a three-claw gear disk provided inside the spindle box at the axial center of the limit plate, a tailstock fixedly installed on one side of the top of the bed, a push rod installed on the internal thread of the tailstock, slide rails fixedly installed on both sides of the tailstock at the top of the bed, a slide seat slidably sleeved between the outer rings of the slide rails, a retaining frame fixedly installed on one side of the slide, a wooden rod fixedly clamped between the three-claw gear disk and the push rod, the wooden rod is arranged through the retaining frame, and the wooden rod is rotatably installed inside the retaining frame.

[0006] Through the above-mentioned structural setting, the lubricating oil is sprayed out from the gap between the adapter and the small glass ball, and the lubricating oil is smeared on the outer ring of the slide rail at the bottom of the slide, completing the lubrication between the slide and the slide rail, achieving the effect of automatic lubrication and sealing to preserve the lubricating oil.

[0007] Preferably, the interior of the slide rail is provided with oil grooves in a linear array, lubricating oil is provided inside the oil grooves, a pump pipe is fixedly installed at the top opening of the oil groove, a hollow tube is slidably installed on the top of the pump pipe, the bottom of the hollow tube is located inside the pump pipe and is adapted to the inner wall of the pump pipe, a spring is fixedly installed on the inner ring of the bottom of the hollow tube, a large glass ball is movably installed inside the pump pipe, a small glass ball is movably installed above the inside of the hollow tube, the outer ring of the hollow tube is located inside the pump pipe and fixedly sleeved with a piston, a sealing cover is fixedly installed on the top of the pump pipe at the oil groove opening, and a mechanical seal is formed between the sealing cover and the hollow tube.

[0008] With the above-mentioned structural arrangement, when the sliding slide is located above the hollow tube and squeezes the hollow tube, the hollow tube is pressed downward. Due to the squeezing of the piston, the lubricating oil inside the working tube is sprayed out to lubricate the slide and the slide rail, so that the slide can slide better. When the slide slides and releases the pressure on the hollow tube, due to the negative pressure inside the working tube, the lubricating oil inside the oil tank is sucked from the inside of the delivery pipe into the inside of the working tube for timely replenishment.

[0009] Preferably, the pump outlet pipe includes an operating pipe and a delivery pipe, the delivery pipe is fixedly connected to the bottom of the operating pipe, the operating pipe is communicated with the delivery pipe, an oil delivery port is opened at the bottom of the operating pipe, and the large glass ball is located above the oil delivery port inside the operating pipe.

[0010] With the above-mentioned structural arrangement, after the hollow tube is squeezed by the slide, when the slide slides out of the restriction on the hollow tube, the spring will push up the hollow tube. Due to the negative pressure inside the pump outlet tube, the small glass balls will be sucked by gravity and block the adapter. The negative pressure inside the pump outlet tube will also be sucked up, which will suck up the large glass balls and suck the lubricating oil inside the oil tank into the inside of the working tube, filling the inside of the working tube and leaving it until it is squeezed and sprayed out next time.

[0011] Preferably, adaptation bevel grooves are provided on both sides of the slide seat at positions corresponding to the positions of the hollow tube, an adaptation set is fixedly installed in the middle of the hollow tube, the small glass ball is located above the adaptation set, a fixed net is fixedly installed on the top of the hollow tube, a push rod is fixedly installed on the bottom of the fixed net, and redundant space is left between the push rod and the adaptation set.

[0012] Through the above-mentioned structural setting, when the sliding slide uses the adapter bevel to squeeze the hollow tube, the hollow tube will drive the spring to contract, so that the bottom of the spring will rest on the top of the large glass ball, which will be blocked, so that the lubricating oil stored in the working tube is squeezed by the piston and squeezed out from the inside of the hollow tube. When the lubricating oil is squeezed out, the small glass ball will be pushed open, and the lubricating oil will be sprayed out from the gap between the adapter and the small glass ball. The lubricating oil will be smeared on the outer ring of the bottom of the slide at the slide rail.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The slide rail structure of the simple turning and milling CNC lathe realizes automatic pumping out lubrication by setting structures such as oil grooves, pump-out pipes, and hollow tubes. When the sliding slide uses the adapter bevel to squeeze the hollow tube, the hollow tube will drive the spring to contract, so that the bottom of the spring rests on the top of the large glass ball. The large glass ball will be blocked, so that the lubricating oil stored in the working tube is squeezed by the piston and squeezed out from the inside of the hollow tube. When the lubricating oil is squeezed out, the small glass ball will be pushed open, so that the lubricating oil will be sprayed out from the gap between the adapter set and the small glass ball, achieving the effect of extrusion lubrication.

[0015] 2. The slide rail structure of the simple turning and milling CNC lathe realizes lubricating oil sealing by setting large glass balls, small glass balls, sealing covers and other structures. When the device is not squeezed, the small glass balls fall on the adapter set and block the adapter set, so that external gas cannot enter the oil tank, and the lubricating oil can be preserved for a long time. This structural setting has the effect of sealing the lubricating oil. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 4 The interior of the slide rail 4 is provided with an oil groove 41 in a linear array, and lubricating oil is provided inside the oil groove 41. A pump outlet pipe 42 is fixedly installed at the top opening of the oil groove 41, and a hollow tube 43 is slidably installed on the top of the pump outlet pipe 42. The bottom of the hollow tube 43 is located inside the pump outlet pipe 42 and is adapted to the inner wall of the pump outlet pipe 42. A spring 44 is fixedly installed on the inner ring of the bottom of the hollow tube 43. A large glass ball 45 is movably installed inside the pump outlet pipe 42, and a small glass ball 46 is movably installed on the top of the hollow tube 43. The outer ring of the hollow tube 43 is located inside the pump outlet pipe 42 and is fixedly sleeved with a piston 47. The top of the pump outlet pipe 42 is located at the opening of the oil groove 41 and a sealing cover 48 is fixedly installed for sealing the pump outlet pipe 42 and the hollow tube 43. A mechanical seal is formed between the sealing cover 48 and the hollow tube 43.

[0024] When the sliding slide 5 is located above the hollow tube 43 and squeezes the hollow tube 43, the hollow tube 43 is pressed downward. Due to the squeezing of the piston 47, the lubricating oil inside the working tube 421 will be sprayed out to lubricate the slide 5 and the slide rail 4, so that the slide 5 can slide better. When the slide 5 slides to release the pressure on the hollow tube 43, due to the negative pressure inside the working tube 421, the lubricating oil inside the oil tank 41 will be sucked from the inside of the delivery pipe 422 to the inside of the working tube 421 for timely replenishment.

[0025] When the device is not squeezed, the small glass ball 46 falls on the adapter sleeve 431, blocking the adapter sleeve 431, preventing external air from entering the oil tank 41. The lubricating oil can be preserved for a long time, avoiding oxidation and consumption after contact with air. Lubricating oil that is in contact with air for a long time will not have a lubricating effect. This structural setting has the effect of sealing the lubricating oil.

[0026] See also Figure 1-Figure 4 The pump outlet pipe 42 includes an operating pipe 421 and a delivery pipe 422. The delivery pipe 422 is fixedly connected to the bottom of the operating pipe 421. The operating pipe 421 and the delivery pipe 422 are connected. An oil delivery port 423 is opened at the bottom of the operating pipe 421, and the large glass ball 45 is located above the oil delivery port 423 inside the operating pipe 421.

[0027] After the hollow tube 43 is squeezed by the slide 5, when the slide 5 slides out of the restriction on the hollow tube 43, the spring 44 will push up the hollow tube 43. Due to the negative pressure inside the pump outlet tube 42, the small glass ball 46 will be sucked by gravity to block the adapter 431. The negative pressure inside the pump outlet tube 42 is still there, which will suck up the large glass ball 45, so that the lubricating oil inside the oil tank 41 is sucked into the inside of the working tube 421, filling the inside of the working tube 421 and leaving it until it is squeezed and sprayed out next time.

[0028] See also Figure 1-Figure 4 , adaptation inclined grooves are opened on both sides of the slide 5 at the corresponding positions of the hollow tube 43, an adaptation set 431 is fixedly installed in the middle of the hollow tube 43, and the small glass ball 46 is located above the adaptation set 431. A fixed net 432 is fixedly installed on the top of the hollow tube 43, and a support rod 433 is fixedly installed at the bottom of the fixed net 432. Redundant space is left between the support rod 433 and the adaptation set 431, which is the activity space of the small glass ball 46.

[0029] When the sliding slide 5 uses the adapter bevel to squeeze the hollow tube 43, the hollow tube 43 will drive the spring 44 to contract, so that the bottom of the spring 44 rests on the large glass ball 45, blocking the oil delivery port 423, so that the lubricating oil stored in the working tube 421 is squeezed by the piston 47 and squeezed out from the inside of the hollow tube 43. When the lubricating oil is squeezed out, the small glass ball 46 will be pushed open, so that the lubricating oil will be sprayed out from the gap between the adapter sleeve 431 and the small glass ball 46. The lubricating oil will be smeared on the outer ring of the slide rail 4 at the bottom of the slide 5, completing the lubrication between the slide 5 and the slide rail 4.

[0030] Working principle: When the device of the present application is used for processing, the movable slide 5 is located at the outer ring of the slide rail 4 so as to adjust the gap between the slide 5 and the workpiece. When the sliding slide 5 uses the adapter bevel to squeeze the hollow tube 43, the hollow tube 43 will drive the spring 44 to contract, so that the bottom of the spring 44 is against the top of the large glass ball 45. The large glass ball 45 blocks the oil delivery port 423, so that the lubricating oil stored in the working tube 421 is squeezed by the piston 47 and squeezed out from the inside of the hollow tube 43. When the lubricating oil is squeezed out, the small glass ball 46 is pushed open, so that the lubricating oil flows from the adapter 431 and the small glass ball 46. The lubricating oil will be sprayed out from the gaps between the glass balls 46, and will be smeared on the outer ring of the bottom of the slide 5 located on the slide rail 4, completing the lubrication between the slide 5 and the slide rail 4. When the slide 5 slides out of the restriction of the hollow tube 43, the spring 44 will push up the hollow tube 43. Due to the negative pressure inside the pump-out tube 42, the small glass balls 46 will be sucked by gravity to block the adapter 431, and the negative pressure inside the pump-out tube 42 will still be there, which will suck up the large glass balls 45, so that the lubricating oil inside the oil tank 41 is sucked into the inside of the working tube 421, filling the inside of the working tube 421 and leaving it until it is squeezed and sprayed out next time.
