Description

Technical Field

[0001] This utility model relates to the technical field of lathe machining auxiliary equipment, and in particular to a lathe workpiece end face leveling and positioning device. Background Technology

[0002] In the field of lathe machining, the leveling and positioning accuracy of the workpiece end face is the core element determining the machining quality. High-precision leveling and positioning can not only effectively reduce dimensional errors caused by workpiece offset, but also reduce tool wear and improve the surface finish of the machined parts, thereby significantly improving the product qualification rate and production efficiency. Any tiny positioning deviation may be amplified in the subsequent cutting process, leading to problems such as out-of-tolerance cylindricity of shaft parts and unqualified end face runout of disc parts, which seriously affects the assembly accuracy and service life of mechanical components. Traditional workpiece end face leveling and positioning methods mostly rely on the operator's experience, manually adjusting the workpiece position and using measuring tools such as dial indicators for multiple measurements and fine adjustments. Therefore, a lathe workpiece end face leveling and positioning device is particularly needed.

[0003] Chinese Patent CN213916145U, published on August 10, 2021, discloses a workpiece end face support device for CNC lathes. This device supports the workpiece through the supporting end of a positioning sleeve, ensuring workpiece clamping rigidity, uniform force distribution, more stable workpiece machining accuracy, and improved tool life. Furthermore, the support mechanism and motion mechanism are integrated, reducing clearance and cumulative errors, significantly improving the axial dimensional accuracy of the workpiece. However, this workpiece end face support device for CNC lathes cannot achieve symmetrical and coordinated precise clamping of the two sets of positioning components during use, leading to workpiece issues during machining. During the process, uneven force can easily cause deviation or shaking. When dealing with workpieces of different sizes and specifications, it is difficult to adapt quickly, which may require frequent replacement of positioning components or adjustment of equipment, increasing processing time and cost, reducing the versatility of the equipment, and making it impossible to achieve precise horizontal displacement of the leveling roller, resulting in low leveling efficiency. It is difficult to quickly adjust the leveling components to the appropriate working position, cannot flexibly adjust the leveling angle, and cannot perform multi-angle, all-round leveling operations on the end face of the workpiece. It cannot meet the strict requirements of high-precision machining for workpiece flatness, thus limiting the improvement of processing quality. Utility Model Content

[0004] The purpose of this invention is to provide a lathe workpiece end face leveling and positioning device to solve the problems mentioned in the background art regarding existing CNC lathe workpiece end face support devices. These devices cannot achieve symmetrical and coordinated precise clamping of two sets of positioning components, leading to workpiece displacement or wobbling during processing due to uneven force. Furthermore, they are difficult to adapt quickly to workpieces of different sizes, potentially requiring frequent replacement of positioning components or equipment adjustments, increasing processing time and cost, and reducing equipment versatility. Additionally, they cannot achieve precise horizontal displacement of the leveling rollers, resulting in low leveling efficiency, difficulty in quickly adjusting the leveling components to the appropriate working position, inability to flexibly adjust the leveling angle, and difficulty in performing multi-angle, all-around leveling operations on the workpiece end face. This fails to meet the stringent requirements for workpiece flatness in high-precision machining, thus limiting the improvement of processing quality.

[0015] 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.

[0016] Please see Figure 1-5 This utility model provides a technical solution: a lathe workpiece end face leveling and positioning device, including a worktable 1, a positioning component 2 fixedly installed on the top of the worktable 1, a placement platform 3 fixedly installed on the top of the worktable 1, and a leveling component 4 fixedly installed on the top of the worktable 1. The positioning component 2 includes a mounting base 201, which is mounted on the worktable 1. A connecting base 202 is fixedly installed on the outer side of the mounting base 201. A sliding groove 203 is formed on the top of the connecting base 202, and a mounting groove 204 is formed on the top of the mounting base 201. A motor 205 is fixedly installed inside. A rotating shaft 206 is fixedly installed on the top of the motor 205. A rotating rod 207 is fixedly installed on the outside of the rotating shaft 206. A limit post 208 is fixedly installed on the top of the rotating rod 207. A connecting rod 209 is rotatably installed on the outside of the limit post 208. A limit post 210 is rotatably installed on the inside of the connecting rod 209. A positioning block 211 is fixedly installed on the bottom of the limit post 210. A clamping head 212 is fixedly installed on the outside of the positioning block 211. A slide rail 213 is fixedly installed on the bottom of the positioning block 211.

[0017] Furthermore, both the first limiting post 208 and the second limiting post 210 are rotatably connected to the connecting rod 209. The connecting rod 209 is located above the rotating rod 207. By setting up the positioning component 2, the rotating shaft 206 is driven by the first motor 205, which drives the rotating rod 207, connecting rod 209, and other components to move in tandem. This causes the two sets of positioning blocks 211 to move in opposite directions along the sliding track formed by the slide groove 203 and the slide rail 213, achieving precise clamping and positioning of the workpiece. This provides a more balanced and stable clamping force, effectively avoiding the workpiece's offset and shaking problems caused by uneven force during processing. This significantly improves the reliability and stability of positioning, thereby ensuring the processing accuracy of the workpiece. The working parameters of the positioning component 2 can be flexibly adjusted according to workpieces of different sizes and specifications, significantly improving the versatility and applicability of the device.

[0018] Furthermore, the connecting seat 202, slide groove 203, rotating rod 207, limiting post one 208, connecting rod 209, limiting post two 210, positioning block 211, clamping head 212, and slide rail 213 are provided in two identical sets. The two sets of connecting seats 202, slide groove 203, rotating rod 207, limiting post one 208, connecting rod 209, limiting post two 210, positioning block 211, clamping head 212, and slide rail 213 are symmetrically distributed about the vertical center line of the rotating axis 206. By providing two sets of connecting seats 202, slide groove 203, rotating rod 207, limiting post one 208, connecting rod 209, limiting post two 210, positioning block 211, clamping head 212, and slide rail 213, and two sets of positioning blocks 211... The simultaneous movement of the two sides applies a balanced clamping force to the workpiece, effectively avoiding workpiece displacement or deformation caused by unilateral force. This ensures that the workpiece is subjected to uniform force during processing and can maintain a more stable state, thereby significantly improving the reliability of workpiece positioning and providing a strong guarantee for subsequent high-precision machining.

[0019] Furthermore, the slide groove 203 and the slide rail 213 are slidably connected, and the size of the first limiting post 208 and the second limiting post 210 are the same. By setting the slide groove 203 and the slide rail 213, it can slide smoothly along the predetermined track, reducing the frictional resistance during the sliding process, improving the smoothness of the operation of the positioning component 2, ensuring that the connecting rod 209 can maintain a stable transmission relationship during rotation, avoiding transmission errors caused by size differences, making the movement of the positioning block 211 more precise, and further improving the accuracy and stability of positioning.

[0020] Furthermore, the combination of the two sets of rotating rods 207 is in the shape of an "I" and the two sets of connecting rods 209 rotate in opposite directions. By setting the combination of the two sets of rotating rods 207 in the shape of an "I" and the two sets of connecting rods 209 rotating in opposite directions, not only is the transmission process simplified and the transmission efficiency improved, but the distance between the two sets of positioning blocks 211 can also be quickly adjusted according to workpieces of different sizes, so as to achieve flexible positioning of workpieces of different specifications and greatly enhance the versatility of the device.

[0021] Furthermore, the leveling component 4 includes a fixing plate 401, which is mounted on the workbench 1. A mounting base plate 402 is fixedly mounted on the top of the fixing plate 401. A second motor 403 is fixedly mounted on the top of the mounting base plate 402. A transmission screw 404 is fixedly mounted on the output end of the second motor 403. A movable seat 405 is threadedly connected to the outer side of the transmission screw 404. A rotating groove 406 is opened on the outer side of the movable seat 405. A rotating disk 407 is rotatably mounted inside the movable seat 405. A handle 408 is fixedly mounted on the outer side of the rotating disk 407. Equipped with a leveling roller 409 and a leveling component 4, the structure, driven by a motor 403 and a transmission screw 404, moves the movable seat 405. This allows for precise horizontal displacement of the leveling roller 409, making the leveling operation more efficient and convenient. The leveling roller 409 can be quickly adjusted to a suitable working position. Operators can flexibly control the leveling roller 409 by rotating the handle 408 to level the workpiece end face. This not only makes operation simple and convenient but also significantly improves the flexibility and accuracy of leveling, ensuring that the workpiece end face achieves higher flatness requirements and meets the needs of high-precision processing.

[0022] Furthermore, the handle 408 and the leveling roller 409 are located on opposite sides of the rotating disk 407. The horizontal center line of the handle 408 and the horizontal center line of the leveling roller 409 are located on different horizontal center lines. By setting the handle 408 and the leveling roller 409, the operator can generate a larger lever arm when turning the handle 408, thereby achieving rotation control of the rotating disk 407 with a smaller operating force, reducing the difficulty of operation, better conforming to different shapes of the workpiece end face, and performing more comprehensive and precise leveling operations on the workpiece end face, effectively improving the flatness of the workpiece end face.

[0023] Working Principle: First, the operator checks whether the worktable 1 is placed stably, ensuring its surface is flat and free of debris to avoid affecting the subsequent workpiece processing accuracy. A comprehensive inspection is then conducted on the positioning component 2, the placement table 3, and the leveling component 4, confirming that all components are securely connected without looseness or damage. The wiring connections of motor 1 (205) and motor 2 (403) are checked to ensure they are normal and in the off position. The operator then places the workpiece to be processed stably on the placement table 3, positioning it approximately in the center of the worktable 1 for easy positioning. The operator starts motor 1 (205), which drives the rotating shaft 206 to begin rotating. The rotating rod 207 on the outer side of shaft 206 rotates accordingly. The limiting post 208 at the top of the rotating rod 207 is linked with the limiting post 210 through the connecting rod 209, thereby driving the two sets of positioning blocks 211 to move towards each other along the sliding track formed by the sliding groove 203 at the top of the connecting seat 202 and the sliding rail 213 at its bottom. As the positioning block 211 moves, its outer clamping head 212 gradually approaches the workpiece until it is tightly attached to the surface of the workpiece, thus accurately clamping and positioning the workpiece. During this process, the rotation angle or time of the motor 205 can be flexibly adjusted according to the size and specifications of the workpiece to achieve the desired position between the two sets of positioning blocks 211. To accommodate different workpieces, the operator starts motor 403, which drives the transmission screw 404 to rotate. The movable seat 405, threaded to the outside of the transmission screw 404, moves horizontally, causing the rotating disk 407 and leveling roller 409 to approach the workpiece end face. The leveling roller 409 is then adjusted to a suitable working position. The operator controls the rotation of the rotating disk 407 by rotating the handle 408 on the outside of the rotating disk 407. Because the handle 408 and the leveling roller 409 are located on opposite sides of the rotating disk 407 and have different horizontal center lines, rotating the handle 408 generates a larger lever arm, requiring less operating force. The leveling roller 409 can be flexibly adjusted in angle. After adjusting the position and angle of the leveling roller 409, it is made to fully contact the end face of the workpiece to perform leveling operation. Through multiple adjustments and operations, the end face of the workpiece is ensured to meet the required flatness requirements. After the workpiece positioning and end face leveling are completed, lathe machining operation can be performed. After machining is completed, motor 1 205 and motor 2 403 are turned off first. Then, motor 1 205 is operated in reverse to make the two sets of positioning blocks 211 move in opposite directions, release the clamping of the workpiece, take out the machined workpiece, and reset the positioning component 2 and the leveling component 4 to prepare for the next machining.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
