Description

Technical Field

[0001] This utility model relates to the field of lathe machining technology, and more specifically, to a fixed fixture for lathe machining. Background Technology

[0002] In the lathe machining industry, fixtures are core components that ensure machining accuracy and improve production efficiency; their performance directly determines product quality and production efficiency. As the manufacturing industry continues to develop towards high-end and precision manufacturing, the complexity of workpiece machining continues to rise, and the requirements for machining accuracy are becoming increasingly stringent. Against this backdrop, the shortcomings of traditional lathe machining fixtures have gradually become apparent, making them unable to meet the demands of modern production.

[0003] The lathe machining fixture proposed in patent CN211439002U uses a servo motor to adjust the spacing between the fixing boxes, thereby better adapting to machining parts of different sizes; at the same time, it uses pneumatically driven clamping columns for clamping operations, which can effectively increase the clamping area and improve the clamping effect when clamping irregular machining parts.

[0004] However, this fixture still has some obvious shortcomings. In terms of adjustment, its adjustment range is relatively limited, making it difficult to meet the machining requirements of large workpieces, and the adjustment accuracy also needs improvement, failing to meet the stringent standards of high-precision machining. Regarding its adaptive capabilities, it lacks the function of automatically adjusting clamping force and position when facing workpieces with complex and varied shapes, making it difficult to ensure stable clamping of the workpiece. From a functional integration perspective, this fixture only has basic clamping functions, lacking functions such as workpiece positioning detection, displacement detection, and clamping force detection, making it unable to effectively coordinate with the lathe control system and hindering the realization of automated production. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model provides a fixed fixture for lathe machining, aiming to improve the overall level of lathe machining and meet the needs of modern manufacturing for high-precision, high-efficiency, and intelligent machining.

[0006] To achieve the above objectives, this utility model discloses a fixed fixture for lathe machining, including a base, an intelligent sensing clamping device, a lifting plate, an adjustment platform, and a positioning detection module;

[0007] The base is divided into cavity one and cavity two by a partition, with cavity one located below cavity two; the lifting plate is installed in cavity one by a ball screw, and the adjustment platform is located in cavity two; the lifting plate and the adjustment platform are connected by four connecting columns.

[0008] A servo motor is fixedly installed inside cavity one, and the servo motor is fixedly installed at the bottom inside the base, with its output end connected to the ball screw; an adjusting plate 1 and an adjusting plate 2 are placed inside cavity two, and toothed grooves are formed on the side of the adjusting plate 1 and the adjusting plate 2 that are close to each other; a servo motor 2 is also fixedly installed inside cavity two, and the servo motor 2 is fixedly installed on the adjusting platform, with a gear fixedly installed at its output end, and the gear meshing with the toothed grooves on the adjusting plate 1 and the adjusting plate 2; connecting blocks are fixedly installed on the upper surfaces of both the adjusting plate 1 and the adjusting plate 2.

[0009] Preferably, the intelligent sensing clamping device is disposed on the upper surface of the base, and has an air chamber inside. Each of the two intelligent sensing clamping devices has a rectangular array of air holes on the side closest to each other, and a clamping rod is placed inside each air hole. A sensor module is installed at one end of the clamping rod, and a piston block is fixedly installed at the other end of the clamping rod. The piston block is adapted to the air hole. An air inlet pipe is fixedly connected to the side of the two intelligent sensing clamping devices far apart from each other, and the air inlet pipe is connected to an air pump.

[0010] Preferably, a positioning detection module is provided on one side of the intelligent sensing clamping device, and the positioning detection module is a laser rangefinder or a vision camera.

[0011] Preferably, the sensor module is equipped with a pressure sensor and a displacement sensor.

[0012] Preferably, sleeves are fixedly installed on the opposite sides of the adjusting plate one and the adjusting plate two. Two symmetrical sliding rods are installed inside the cavity two. The sliding rods are slidably connected to the base. The two sleeves are respectively fitted onto the outer surfaces of the two sliding rods.

[0013] Preferably, the partition plate is provided with through holes through which the four connecting posts and the ball screw pass.

[0014] Preferably, the upper surface of the base has two slides, and the top of the connecting block passes through the slides and is fixedly connected to the bottom surface of the intelligent sensing clamping device.

[0015] Therefore, this utility model is a lathe machining fixture using the above-described structure, and its beneficial effects are as follows:

[0016] (1) Flexible adjustment of height and spacing: The lifting plate, the adjustment platform and related drive structure are set up. The ball screw driven by the servo motor can make the lifting plate drive the adjustment platform to achieve vertical lifting and lowering, so as to meet the clamping requirements of workpieces of different heights. The servo motor drives the gear and the tooth groove of the adjustment plate to accurately adjust the horizontal distance between the first adjustment plate and the second adjustment plate, thereby adjusting the distance between the two clamping devices to adapt to workpieces of different sizes, which greatly improves the adaptability of the fixture to various workpieces.

[0017] (2) Intelligent and precise clamping: The sensor module in the intelligent sensing clamping component integrates pressure and displacement sensors, which can monitor the clamping force and clamping position in real time. During the clamping process, it can automatically adjust the extension and retraction of the clamping rod and the clamping force according to the changes in the workpiece surface contour, so as to achieve adaptive and precise clamping of the workpiece. Especially for irregular or easily deformable workpieces, it can effectively avoid problems such as loose clamping and deformation, and ensure processing accuracy and quality.

[0018] (3) High-efficiency positioning and detection: The positioning and detection module uses a laser rangefinder or vision camera to quickly and accurately detect the position and posture of the workpiece before clamping, providing reliable data support for precise clamping, reducing the time and error of manual measurement and alignment, and improving clamping efficiency and automation.

[0028] like Figure 1-2 As shown, this utility model provides a fixed fixture for lathe machining, including a base 1, an intelligent sensing clamping device 2, a lifting plate 7, an adjustment platform 12, and a positioning detection module 3;

[0029] The base 1 is divided into cavity 5 and cavity 6 by partition 10. Cavity 5 is located below cavity 6. Lifting plate 7 is installed in cavity 5 by ball screw 9. Adjustment platform 12 is located in cavity 6. Lifting plate 7 and adjustment platform 12 are connected by four connecting columns 11.

[0030] A servo motor 8 is fixedly installed inside the cavity 5. The servo motor 8 is fixedly installed at the bottom inside the base 1, and its output end is connected to the ball screw 9. The rotation of the servo motor 8 drives the ball screw 9 to rotate, thereby realizing the vertical up and down movement of the lifting plate 7, which in turn drives the vertical up and down movement of the adjustment platform 12. The partition plate 10 is also provided with through holes for the four connecting columns 11 and the ball screw 9 to pass through, ensuring the smoothness of the up and down movement of the lifting plate 7.

[0031] Inside cavity 26, adjustment plate 14 and adjustment plate 2 15 are placed. Gear grooves are formed on the side of adjustment plate 14 and adjustment plate 2 15 that are close to each other. Servo motor 2 17 is also fixedly installed inside cavity 26. Servo motor 2 17 is fixedly installed on adjustment platform 12, and gear 16 is fixedly installed at its output end. Gear 16 meshes with the gear grooves on adjustment plate 14 and adjustment plate 2 15. Connecting block 13 is fixedly installed on the upper surface of adjustment plate 14 and adjustment plate 2 15. Two slides are formed on the upper surface of base 1. The top of connecting block 13 passes through the slide and is fixedly connected to the bottom surface of intelligent sensing clamping device 2. The rotation of servo motor 2 17 drives adjustment plate 14 and adjustment plate 2 15 to move left and right. Under the connection of connecting block 13, the two intelligent sensing clamping devices 2 can move closer or further apart.

[0032] like Figure 3 As shown, sleeves 18 are fixedly installed on the sides of the adjusting plate 14 and the adjusting plate 15 that are far apart from each other. Two symmetrical sliding rods 19 are also installed inside the cavity 2 6. The sliding rods 19 are slidably connected to the base 1, ensuring the stability of the sliding rods 19 when they slide up and down with the adjusting platform 12. The two sleeves 18 are respectively fitted on the outer surface of the two sliding rods 19, which better guides the movement of the adjusting plate 14 and the adjusting plate 15.

[0033] like Figure 4 As shown, the intelligent induction clamping device 2 is mounted on the upper surface of the base 1, and has an air chamber 21 inside. On the side of the two intelligent induction clamping devices 2 that are close to each other, there is a rectangular array of air holes 22. Each air hole 22 contains a clamping rod 24. A sensor module 25 is installed at one end of the clamping rod 24. The sensor module 25 contains a pressure sensor and a displacement sensor, which can monitor the clamping force and clamping position in real time, automatically adjusting the extension and retraction of the clamping rod and the clamping force to achieve adaptive and precise clamping of the workpiece. A piston block 23 is fixedly installed at the other end of the clamping rod 24. The piston block 23 is adapted to the air hole 22 to ensure airtightness during inflation. An air inlet pipe 4 is fixedly connected to the side of the two intelligent induction clamping devices 2 that is far from each other. The air inlet pipe 4 is connected to an air pump to realize inflation and deflation. A positioning detection module 3 is also provided on one side of the intelligent sensing clamping device 2. The positioning detection module 3 is a laser rangefinder or vision camera, which automatically detects the position and posture of the workpiece before clamping, providing data support for precise clamping.

[0034] In use, firstly, servo motor 8 is started, and the height of the adjustment platform 12 is adjusted according to the calculation results to bring the intelligent sensing clamping device 2 to a suitable vertical position. Then, servo motor 17 is started, driving gear 16 to rotate, causing adjustment plate 14 and adjustment plate 15 to move horizontally relative to each other, adjusting the horizontal distance between the two intelligent sensing clamping devices 2 to accommodate the size of the workpiece. The workpiece is placed between the two intelligent sensing clamping devices 2, and air is injected into the air chamber 21 through the air inlet pipe 4. The air pressure pushes the piston block 23, causing the clamping rod 24 to extend and contact the workpiece. At this time, the pressure sensor and displacement sensor monitor the clamping force and clamping position in real time and feed the data back to the controller. Based on the feedback data, the controller automatically adjusts the clamping force of the clamping rod 24 by increasing or decreasing the air pressure to achieve precise clamping of the workpiece.

[0035] In summary, this utility model provides a fixed fixture for lathe machining with the above-described structure, which improves the overall level of lathe machining and meets the needs of modern manufacturing for high-precision, high-efficiency, and intelligent machining.
