Description

Technical Field

[0001] This utility model relates to the technical field of machine tool workpiece clamping components, specifically an adaptive machine tool workpiece clamping component. Background Technology

[0002] A workpiece refers to a product component in the manufacturing process, also called a part, component, shell, hardware part, etc. When processing some workpieces, clamping components are needed to facilitate stable positioning of the workpiece.

[0003] For example, the workpiece clamping and positioning assembly with announcement number CN216178629U includes a fixed base. A fixed plate is welded to one end of the upper surface of the fixed base. A servo motor is fixedly installed on one side of the fixed plate. The output end of the servo motor is connected to a lead screw. This device solves the problem that existing workpiece clamping assemblies are inconvenient to clamp workpieces and reduce the stability of workpiece processing.

[0004] Most of the aforementioned existing technologies improve the overall structure. While existing machine tool workpiece clamping assemblies solve the problem of inconvenient workpiece clamping during operation, the workpieces to be clamped vary depending on the parts required for processing. Existing clamping devices are generally not convenient for adjusting the position of the clamps, resulting in poor clamping effect when dealing with workpieces of different shapes, and they are prone to failure to clamp, thus reducing the applicability of the device. Utility Model Content

[0005] The purpose of this invention is to provide an adaptive machine tool workpiece clamping assembly to solve the problem mentioned in the background art that existing clamping assemblies are inconvenient to adjust during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adaptive machine tool workpiece clamping assembly, comprising a limiting support assembly, a sliding clamping assembly slidably mounted above the limiting support assembly, and a threaded moving assembly disposed below the limiting support assembly; the sliding clamping assembly includes a sliding block, and the workpiece can be adaptively clamped through the internal structure of the sliding clamping assembly in conjunction with the internal structure of the limiting support assembly; the threaded moving assembly includes a mounting frame, and the device can be easily moved and adjusted through the internal structure of the threaded moving assembly.

[0007] Furthermore, the limiting support assembly includes a fixed base, and a slider is fixedly installed below the fixed base.

[0008] Furthermore, mounting plates are fixedly installed at the four upper corners of the fixed base, and a rotating rod is rotatably installed inside each mounting plate.

[0009] Furthermore, a placement platform is provided above the fixed base, and a hydraulic device is fixedly installed below the placement platform. A telescopic rod is splinedly connected to the lower part of the hydraulic device, and the lower part of the telescopic rod is connected to the upper part of the fixed base.

[0010] Furthermore, limit rods are fixedly installed at the four lower corners of the placement platform, and a limit frame is fitted on the outer surface of each limit rod, with a sliding block fixedly installed above each limit frame.

[0011] Furthermore, the lower part of each sliding block is rotatably connected to the upper part of the rotating rod, and a reserved groove is provided inside each sliding block.

[0012] Furthermore, a clamping plate is slidably mounted above each of the sliding blocks, and a fixing plate is fixedly mounted below each of the clamping plates.

[0013] Furthermore, each of the sliding blocks has a threaded bolt installed on its side end, and each of the clamping plates is slidably installed above the sliding block through a fixed plate and a reserved slot and bolt.

[0014] Furthermore, support legs are fixedly installed on both the left and right sides of the mounting frame, and a threaded rotating rod is rotatably installed inside the mounting frame, with a connecting shaft fixedly installed on the side end of the threaded rotating rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This adaptive machine tool workpiece clamping assembly works by removing the bolt along the side end of the sliding block, then lifting the clamping plate upwards to remove the fixing plate from the reserved slot. After inserting the fixing plate into the reserved slot at the designated position, the bolt is reinstalled for limiting. Then, the hydraulic device lifts the placement table, and the sliding block pulls the rotating rod to rotate while the mounting plate retracts the sliding block, causing the four sliding blocks to move closer to the center. This allows for easy adjustment of the clamping position during use, thus meeting the clamping operation requirements for workpieces of different shapes and improving the flexibility of the device. Furthermore, the power source drives the connecting shaft to rotate, which in turn drives the threaded rod to rotate, thereby enabling the rotating threaded rod to engage with the internal thread of the slider. In conjunction with the mounting frame to limit the slider, the slider and the fixed base above can be moved, allowing the device to be quickly displaced during use, facilitating the adjustment of the clamped workpiece and enhancing the device's performance.

[0018] 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.

[0019] Example 1: Please refer to Figures 1-5An adaptive machine tool workpiece clamping assembly is disclosed to address the problem that existing machine tool workpiece clamping assemblies are inconvenient to adjust the clamping position according to the workpiece shape during use. The assembly includes a limiting support assembly 1, a sliding clamping assembly 2 slidably mounted above the limiting support assembly 1, and a threaded moving assembly 3 disposed below the limiting support assembly 1. The sliding clamping assembly 2 includes a sliding block 21, and its internal structure, in conjunction with the internal structure of the limiting support assembly 1, enables adaptive clamping of the workpiece. The threaded moving assembly 3 includes a mounting frame 31, and its internal structure facilitates the movement and adjustment of the device. The limiting support assembly 1 includes a fixed base 11, a slider 12 fixedly mounted below the fixed base 11, and mounting plates 13 fixedly mounted at the four corners above the fixed base 11. Each mounting plate 13 has a rotating component rotatably mounted inside. A platform 15 is provided above the moving rod 14 and the fixed base 11. A hydraulic device 17 is fixedly installed below the platform 15. A telescopic rod 18 is splinedly connected to the lower part of the hydraulic device 17. The lower part of the telescopic rod 18 is connected to the upper part of the fixed base 11. Limiting rods 16 are fixedly installed at the four corners of the lower part of the platform 15. A limiting frame 22 is fitted on the outer surface of each limiting rod 16. A sliding block 21 is fixedly installed above each limiting frame 22. The lower part of each sliding block 21 is rotatably connected to the upper part of the rotating rod 14. A reserved groove 23 is opened inside each sliding block 21. A clamping plate 24 is slidably installed above each sliding block 21. A fixing plate 25 is fixedly installed below each clamping plate 24. A plug 26 is threadedly installed on the side end of each sliding block 21. Each clamping plate 24 is slidably installed above the sliding block 21 through the fixing plate 25 in conjunction with the reserved groove 23 and the plug 26.

[0020] like Figures 1-5 As shown, the user places the workpiece on the placement platform 15 and then activates the hydraulic actuator 17. The hydraulic actuator 17 pushes the telescopic rod 18 to extend and retract, thereby lifting part of the placement platform 15. As the placement platform 15 moves upward, the sliding block 21 pulls the rotating rod 14 to rotate. Since the bottom of the rotating rod 14 is limited by the mounting plate 13, when the placement platform 15 is lifted, it will drive the four sliding blocks 21 to move towards the center, thereby quickly clamping the workpiece on the placement platform 15. When the clamped workpiece changes, the user first rotates the plug 26 on one side of the sliding block 21 to remove it from the sliding block 21, then lifts the clamping plate 24 upward to remove it from the reserved slot 23. Then, according to the shape of the workpiece, the user adjusts the position of the fixed plate 25 to be inserted into the reserved slot 23, and then re-inserts the clamping plate 24 into the reserved slot 23, and then fixes it with the plug 26. This allows the device to self-adjust, making it convenient to clamp workpieces of different shapes.

[0021] Example 2: Figures 1-6The technical solution shown, based on Embodiment 1, further discloses, in order to solve the problem that existing machine tool workpiece clamping assemblies are inconvenient to change the clamping position during use, that: support legs 32 are fixedly installed on both the left and right sides of the mounting frame 31, a threaded rotating rod 33 is rotatably installed inside the mounting frame 31, and a connecting shaft 34 is fixedly installed on the side end of the threaded rotating rod 33.

[0022] like Figures 1-6 As shown, during assembly, the user first connects the power source to one side of the connecting shaft 34, then the assembled limiting support assembly 1 is threaded onto the outer surface of the threaded rotating rod 33 along the position of the slider 12. At the same time, the slider 12 is slidably installed inside the mounting frame 31. Then, the user starts the power source, which drives the connecting shaft 34 to rotate, thereby driving the threaded rotating rod 33 to rotate inside the mounting frame 31. After rotation, it engages with the internal thread of the slider 12, thereby pushing the slider 12 to slide within the mounting frame 31, thereby driving the limiting support assembly 1 and other parts to move, so that the device can be easily adjusted in position during use.
