Description

Technical Field

[0001] This invention relates to the field of lathe equipment technology, specifically to a horizontal lathe with a self-locking positioning structure. Background Technology

[0002] Machine tools are essential tools for human production and a significant indicator of the level of social productivity. Ordinary machine tools have a history of nearly two centuries. In 1797, the British mechanical inventor Maudsley created the modern lathe, which uses a leadscrew to drive the tool post.

[0003] Currently, in the use of some horizontal lathes, the position of parts is generally changed by a lead screw. The rotation of the rollers and the transmission components control the movement of the parts on the lead screw to fit the machining position. Although the movement of the lead screw is accompanied by a certain degree of self-locking stability, the machining vibration of the lathe cannot be avoided. This causes the rollers to rotate, which drives the transmission components and causes the cutting tool to shift, ultimately affecting the machining quality of the parts. In addition, the movement of the lead screw will also cause a certain degree of wear. The wear gap can also cause the machining tool to easily shift due to the vibration of the lathe. Therefore, a horizontal lathe with a self-locking positioning structure is proposed to solve the above problems. Summary of the Invention

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a horizontal lathe with a self-locking positioning structure, which has the following beneficial effects:

[0018] 1. The horizontal lathe with this self-locking positioning structure can automatically lock the entire adjusting component after it is in a fixed position through the locking mechanism. This prevents the threaded sleeve from rotating and shifting due to the vibration of the lathe. The self-locking is achieved by the threaded transmission mechanism itself, and the position is fixed by the gear locking mechanism. Therefore, with double locking, it is difficult for the adjusting component to shift, which would cause the workpiece to shift, thereby improving the stability of the entire machining process.

[0019] 2. The horizontal lathe with this self-locking positioning structure provides a buffer rotation space during the rotation of the dial wheel through the set torsion member, which avoids the instantaneous rotational displacement of the dial wheel caused by external force. With the buffer rotation space, the rotation of the dial wheel cannot directly control the displacement of the adjusting member, but only indirectly controls the displacement of the adjusting member after rotating to a certain angle. Furthermore, the initial rotation of the dial wheel can also unlock the entire locking member, which is convenient for subsequent adjustment and displacement.

[0020] 3. The horizontal lathe with this self-locking positioning structure uses an extrusion component to apply oil to the surface of the lead screw, thereby maintaining the lubrication of the lead screw. Each time the dial wheel is rotated, a certain amount of extrusion force is generated, which in turn squeezes the internal lubricating oil out and drips onto the surface of the lead screw, achieving automatic lubrication and reducing the wear of the lead screw caused by the rotation of the threaded sleeve.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-8 A horizontal lathe with a self-locking positioning structure includes a machine tool body 1; a workpiece 2 for cutting fixed parts; and a movable self-locking component 3 for moving the tool mounted on the workpiece 2 and automatically locking it. The movable self-locking component 3 includes an adjusting component, a torsion component 306, and a locking component 307. The adjusting component is used to control the position movement of the workpiece 2, and the locking component 307 is used to self-lock the adjusted component after it has moved.

[0032] In this embodiment, the adjusting component includes a dial wheel 301, which is connected to a first gear 303 via a torsion member 306. A second gear 304 meshes with the surface of the first gear 303, and a threaded sleeve 305 is fixedly connected to the second gear 304. A lead screw 308 is threadedly connected to the inside of the threaded sleeve 305, and both ends of the lead screw 308 are fixed to the machine tool body 1. The dial wheel 301 serves as an input component directly controlled by the operator, and its rotational motion is transmitted to the first gear 303 via the torsion member 306. The first gear 303 and the second gear 304 constitute a single-stage reduction or transmission ratio conversion mechanism, and parameters such as module and number of teeth can be designed according to actual needs to adapt to different movement accuracy and torque requirements. The second gear 304 is fixedly connected to the threaded sleeve 305, which can directly transmit rotational motion to the threaded sleeve 305. The threaded sleeve 305 and the lead screw 308 form a helical transmission pair, converting rotational motion into linear motion along the axial direction of the lead screw 308, thereby driving the connected workpiece 2 to achieve lateral feed or position adjustment. The lead screw 308 is fixed at both ends to the machine tool body 1, providing a stable support base and guiding reference to ensure the rigidity and accuracy of the transmission process. This adjusting component has a compact structure, high transmission efficiency, and combines the intuitiveness of manual operation with the reliability of mechanical transmission.

[0033] Furthermore, a fixed plate 310 is fixedly connected to the workpiece 2, and a slide rod 309 is slidably connected to the fixed plate 310. The slide rod 309 is located below the lead screw 308, and both ends of the slide rod 309 are connected to the machine tool body 1. The fixed plate 310 serves as a key connection and load-bearing component between the workpiece 2 and the moving self-locking component 3, not only transmitting driving force but also enhancing the overall structural rigidity. The slide rod 309, preferably a high-hardness optical shaft or linear guide, cooperates with the sliding bearing or linear bushing on the fixed plate 310 to form an auxiliary guiding and supporting mechanism. The slide rod 309 is arranged parallel to the lead screw 308; this vertical arrangement effectively counteracts the overturning moment generated during the movement of the workpiece 2, preventing jamming or accuracy deviations due to uneven force distribution. Both ends of the slide rod 309 are rigidly connected to the machine tool body 1 via mounting bases or flanges. Its installation accuracy ensures the parallelism between the slide rod 309 and the lead screw 308, thus providing precise, stable, and low-friction linear guidance for the movement of the workpiece 2. The slide rod 309 and the lead screw 308 together constitute a dual support and guiding system for the workpiece 2, significantly improving the smoothness, load-bearing capacity, and vibration resistance of the movement process, ensuring long-term positional stability and repeatability during cutting.

[0034] Furthermore, the torsion member 306 includes a hollow sleeve 3061, which is fixedly connected to the dial wheel 301. A rotating shaft 3064 is slidably connected inside the hollow sleeve 3061. A spiral groove 3063 is formed on the surface of the rotating shaft 3064. A sliding pin 3062 is fixedly connected to the inner wall of the hollow sleeve 3061 and slidably connected to the spiral groove 3063. A pressure plate 3065 is rotatably connected to the end face of the hollow sleeve 3061 and is connected to the locking member 307. This hollow sleeve 3061 serves as the core housing for power transmission and buffer conversion. One end is fixedly connected to the operating dial wheel 301, allowing direct input of the rotational torque applied by the operator. The rotating shaft 3064 is axially slidably connected inside the hollow sleeve 3061, and this rotating shaft 3064 is a key component that ultimately outputs torque to the first gear 303. To achieve a unique buffering and unlocking function, a spiral groove 3063 is precision-machined on the outer surface of the rotating shaft 3064. Simultaneously, a sliding pin 3062 is fixedly installed on the inner wall of the hollow sleeve 3061, precisely nested and slidably connected within the spiral groove 3063. The spiral groove 3063 and sliding pin 3062 constitute a sophisticated differential mechanism: when the dial wheel 301 is rotated, causing the hollow sleeve 3061 to begin rotating, the sliding pin 3062 does not immediately drive the rotating shaft 3064 to rotate. Instead, it first slides relative to the shaft along the trajectory of the spiral groove 3063. This process first converts the operator's input rotational motion into a relative axial displacement between the hollow sleeve 3061 and the rotating shaft 3064. Only after the sliding pin 3062 reaches the end of the spiral groove 3063 and enters its hard stop point is the torque fully transmitted, thereby driving the rotating shaft 3064 to rotate synchronously. This feature provides the system with valuable initial buffer travel, effectively avoiding misoperation caused by accidental contact or vibration. A pressure plate 3065 is rotatably connected to the end face of the hollow sleeve 3061 via a bearing or bushing. This pressure plate 3065 acts as an intermediate linkage component, its unique feature being that it can be pushed and pulled along with the axial movement of the hollow sleeve 3061, while maintaining its own free rotation relative to the hollow sleeve 3061, thus not interfering with normal rotary transmission. The pressure plate 3065 is ultimately connected to the locking component 307, precisely transmitting the axial displacement generated by the hollow sleeve 3061 to the locking mechanism to control the switching between its "locked" and "unlocked" states.

[0035] Furthermore, a support frame 302 is rotatably connected to the surface of the rotating shaft 3064, and a threaded sleeve 305 is rotatably connected to the support frame 302. A connecting spring 3066 is sleeved on the surface of the rotating shaft 3064. One end of the connecting spring 3066 is fixedly connected to the support frame 302, and the other end is fixedly connected to the pressure plate 3065. To achieve automatic reset of the torsion member 306 and maintain the state of the locking member 307, a connecting spring 3066 is sleeved on the surface of the rotating shaft 3064. This connecting spring 3066 is preferably a compression helical spring, with one end fixedly connected to the stationary support frame 302 and the other end fixedly connected to the axially movable pressure plate 3065. This arrangement ensures that the connecting spring 3066 is always in a pre-compressed or pre-tensioned state, depending on the assembly relationship. Its elastic force is manifested as follows: after the operator releases the dial 301, the elastic restoring force stored in the spring will automatically push or pull the pressure plate 3065, thereby causing the hollow sleeve 3061 connected to it to reset axially. This reset action forces the sliding pin 3062 to slide back from the end of the spiral groove 3063 to its neutral position, preparing for the next operation with a buffer stroke. On the other hand, the reset of the tablet 3065 also synchronously drives the locking member 307 to move from the unlocked state to the locked position, thereby automatically locking the transmission system without human intervention, ensuring the safety and stability of the processing position.

[0036] In addition, the locking component 307 includes a sliding plate 3074, which is fixed to the pressure plate 3065. A V-groove 3075 is formed on the sliding plate 3074. The sliding plate 3074 is slidably connected to the support frame 302. A sliding shaft 3076 is slidably connected within the V-groove 3075. A locking strip 3072 is connected to the sliding shaft 3076. The locking strip 3072 has teeth, and a locking gear 3071 engages with the teeth. A toothed groove 3073 is formed within the lead screw 308, and the locking gear 3071 meshes inside the toothed groove 3073. The V-groove 3075 is precision-machined on the sliding plate 3074, and its unique configuration is key to achieving bidirectional locking. The sliding shaft 3076 is slidably connected within the V-groove 3075, and both ends of the sliding shaft 3076 are connected to two locking strips 3072 respectively. The locking bar 3072 is provided with precision teeth that engage with the external teeth of a locking gear 3071, thereby restricting its free rotation. The final locking is achieved by the lead screw 308. Within a specific section of the lead screw 308, continuous toothed grooves 3073 are formed axially. Under the push of the locking bar 3072, some teeth of the locking gear 3071 can embed and mesh inside these grooves 3073. When the pressure plate 3065 moves axially under the operation of the dial wheel 301, it pushes the slide plate 3074 to slide. The V-groove 3075 on the slide plate 3074 is displaced, driving the sliding shaft 3076 within the groove to move laterally via its inclined surface. The sliding shaft 3076 then drives the locking bars 3072 on both sides to move towards or away from each other. When locking is required, the locking bar 3072 opens outward under the action of the V-groove 3075, pushing the locking gear 3071 to tightly mesh with the tooth groove 3073 in the lead screw 308. Since the lead screw 308 is fixed and does not rotate, the meshing of the gear and the tooth groove 3073 completely locks the rotational freedom of the locking gear 3071, thereby restricting any displacement of the entire support frame 302 and its transmission components, forming a highly efficient and reliable two-way mechanical self-locking mechanism.

[0037] It is worth noting that there are two sets of locking components 307, and the two sets of locking components 307 are symmetrically distributed about the center of the support frame 302. The threaded sleeve 305 is located between the two locking components 307. Each set of locking bars 3072 is provided with a limit rod 3077, which is slidably connected to the support frame 302. The threaded sleeve 305 is located at the center between the two locking components 307. This layout allows the constraint force generated by the locking action to act evenly and symmetrically on the transmission core—the threaded sleeve 305 and its supporting structure, effectively avoiding uneven loading, jamming, or deformation of the mechanism that may be caused by unilateral locking, thereby ensuring the stability and accuracy of locking. Each set of locking bars 3072 is provided with a limit rod 3077. One end of the limit rod 3077 is fixed to the locking bar 3072, and the other end is slidably connected to the support frame 302 through a linear bearing or guide sleeve. The main purpose of the limiting rod 3077 is to provide precise guidance and limitation for the lateral reciprocating motion of the locking bar 3072. It strictly constrains the locking bar 3072 to move only along a preset straight trajectory, preventing it from deflecting or twisting under the drive of the V-groove 3075, thereby ensuring that the teeth on the locking bar 3072 maintain a precise meshing and disengagement state with the locking gear 3071. At the same time, the limiting rod 3077 also bears the lateral force generated during the locking process, reducing the load on the V-groove 3075 and the sliding shaft 3076, and improving the rigidity and durability of the entire locking component 307.

[0038] It is worth noting that the assembly also includes an extrusion component 4, which includes an oil pipe 403. The bottom of the oil pipe 403 is connected to a branch pipe 404, and the bottom of the branch pipe 404 is connected to two flow pipes 405. The end faces of the flow pipes 405 are all located directly above the lead screw 308. A piston 406 is connected to the pressure plate 3065 via a connecting rod. The piston 406 is slidably connected inside the oil pipe 403. A guide pipe 401 is connected to the surface of the oil pipe 403, and an oil filling port 402 is provided on the guide pipe 401. The guide pipe 401 is connected to the fixed plate 310. The power of this assembly comes from the linkage of the locking mechanism. Specifically, the piston 406 is connected to the pressure plate 3065 via a rigid connecting rod. The piston 406 maintains a precise sliding fit with the inner cavity of the oil pipe 403, thus forming a simple plunger pump structure. When the dial 301 is operated, ultimately causing the pressure plate 3065 to move axially, this movement is converted into the reciprocating motion of the piston 406 inside the oil pipe 403 via a connecting rod. Furthermore, a guide pipe 401 is connected to the upper surface of the oil pipe 403. One end of the guide pipe 401 serves as an oil inlet channel communicating with the inner cavity of the oil pipe 403, while the other end is fixedly connected to the fixing plate 310, thus supporting and securing the entire lubrication system. A filler port 402 is provided on the wall of the guide pipe 401, equipped with a sealing cap or oil cup, serving as the inlet for adding lubricating oil from the outside into the system. When lubricating oil is injected through the filler port 402, it fills the inner cavity of the oil pipe 403 via the guide pipe 401. When the piston 406 is pushed inward by the connecting rod, it will squeeze the lubricating oil in the chamber, forcing it to flow through the branch pipe 404 and finally discharge it in the form of droplets from the ends of the two flow pipes 405, thereby achieving timed and quantitative lubrication of the lower lead screw 308.

[0039] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0040] The working principle is as follows: First, the workpiece to be processed is mounted on the three-jaw chuck of the machine tool body 1. Then, the workpiece 2 is moved to the point where it needs to be processed. During the lateral movement of the workpiece 2, the operator needs to control the rotation of the dial wheel 301. The rotation of the dial wheel 301 will synchronously drive the rotation of the hollow sleeve 3061. The hollow sleeve 3061 has a sliding pin 3062 inside. Therefore, when the dial wheel 301 rotates momentarily, the rotating shaft 3064 will not rotate. Only when the sliding pin 3062 rotates to the limit position of one end of the spiral groove 3063 will it indirectly drive the rotation of the rotating shaft 3064. Then, the rotation of the rotating shaft 3064 drives the rotation of the first gear 303. Through the meshing of the bevel gears, the threaded sleeve 305 will be driven to rotate. The threaded sleeve 305 is threadedly connected to the lead screw 308. The sleeve 305 will synchronously drive the fixed plate 310 and the workpiece 2 connected to the fixed plate 310 to slide laterally, realizing position conversion. When it moves to the desired position, the dial 301 is released. The elastic force of the connecting spring 3066 will push the pressure plate 3065 to move back, thereby driving the hollow sleeve 3061 to rotate in the opposite direction, thereby controlling the sliding pin 3062 to be located in the middle position of the spiral groove 3063. Considering the forward and reverse rotation of the dial 301, the sliding pin 3062 must be in the middle position of the spiral groove 3063. The clockwise rotation of the dial 301 will control the sliding pin 3062 to move to the rear end of the spiral groove 3063, while the counterclockwise rotation of the dial 301 will control the sliding pin 3062 to move to the front end of the spiral groove 3063. At this time, the connecting spring 3066 forms a pulling force, rather than a compressive force. Therefore, the entire dial 301 cannot control the movement of the workpiece 2 after initially rotating a certain angle. Instead, it will control its displacement after rotating a certain angle. This is to avoid the situation where, under the impact of external forces, if the dial adopts a direct drive method, it will directly control the displacement of the workpiece 2, thereby causing a collision or tool misalignment.Furthermore, when the entire dial 301 is in a natural, unforced state, the sliding shaft 3076 will be located at the bottom of the V-shape of the V-groove 3075. At this time, the sliding shaft 3076 will control the locking strip 3072 and the locking gear 3071 to form a locking process. The part of the locking gear 3071 that is close to the lead screw 308 will mesh with the internal teeth of the tooth groove 3073. Therefore, the locking gear 3071 is limited by the locking strip 3072 and cannot rotate. Consequently, the threaded sleeve 305 on the entire support frame 302 cannot move, so the overall position achieves a self-locking state. During the initial rotation of the dial 301, it will control the hollow sleeve 3061 to move forward or backward, thereby driving the pressure plate 3065 to move forward or backward. The pressure plate 3065 will then drive the slide plate 3074 to move forward and backward synchronously. Then, the sliding shaft 3076 will slide laterally within the V-groove 3075, causing the two locking bars 3072 to retract inward, disengaging the locking bars 3072 from the locking gear 3071. At this point, the locking gear 3071 is in a free state. When the dial wheel 301 is rotated again, the rotating shaft 3064 rotates, which drives the first gear 303 to move, thus forming the aforementioned displacement process. Therefore, the initial rotation of the dial wheel 301 also has the effect of unlocking. The movement of the threaded sleeve 305 will drive the support frame 302 to move laterally. The support frame 302 will then drive the locking gear 3071 to rotate and move laterally within the teeth on the tooth groove 3073. The entire system utilizes the self-locking mechanism between the teeth to self-lock the adjustment part of the lathe, ensuring stability during the machining process. However, if the vibration generated by the lathe causes the control wheel 301 to rotate, it will not directly cause the workpiece 2 to shift indirectly. Furthermore, the elasticity of the entire connecting spring 3066 will also hinder the vibration force and limit its control of the rotation of the control wheel 301. If the vibration force controls the self-rotation of the first gear 303 and the second gear 304, it will be restricted by the threads of the lead screw 308 and the threaded sleeve 305, as well as by the locking restriction of the locking gear 3071 on the support frame 302, and will also be unable to control the movement of the threaded sleeve 305. Meanwhile, the technical solution also includes an extrusion component 4 for "self-lubricating" the surface of the lead screw 308. The operator can inject lubricating oil from the outside through the oil filling port 402, which then flows into the inside of the oil pipe 403. Next, it flows into the inside of the flow pipe 405 through the branch pipe 404, flows out from the drip head at the end of the pipe, and finally drips onto the surface of the lead screw 308 to achieve lubrication. When the entire dial wheel 301 rotates, it will also drive the piston 406 to move forward a small distance through the forward movement of the hollow sleeve 3061. The forward movement of the piston 406 will squeeze the lubricating oil inside the oil pipe 403, thus squeezing out the oil.During the initial lubrication stage, there is no lubricating oil inside the oil pipe 403 because the width of the piston 406 blocks the oil outlet of the guide pipe 401. If lubrication is needed, the dial 301 needs to be rotated in the reverse direction to control the pressure plate 3065 to move backward, thereby driving the piston 406 to move backward, exposing the oil outlet of the guide pipe 401, allowing the lubricating oil inside to enter the oil pipe 403. Then, the dial 301 is rotated in the forward direction to control the piston 406 to move forward, thereby squeezing out the lubricating oil inside the oil pipe 403.
