Description

Technical Field

[0001] This utility model relates to a limiting device, specifically a limiting device for boring shaft parts, belonging to the field of shaft parts processing technology. Background Technology

[0002] Shafts are an important component of machinery and equipment. They are mainly used to support transmission parts, transmit torque, and bear loads. When machining shafts, they generally need to be fixed first to facilitate subsequent machining operations.

[0003] Chinese patent application publication number CN221640243U discloses a clamping and limiting device for machining shaft-type parts. This utility model uses a cylinder to push a moving block to move horizontally, thereby causing a rotating rod to move horizontally. The force of this movement, combined with components such as a rectangular block, positioning plate, positioning block, baffle, and slider in the clamping device, achieves the effect of fixing and clamping the parts.

[0004] Although the above-mentioned patent solution can clamp the processed parts, the clamping and limiting device in the above-mentioned patent uses a rectangular block to clamp the parts. When clamping round or irregularly shaped parts, the contact surface between the rectangular block and the parts is narrow, which makes the clamping of the parts unstable and thus easily damages the parts.

[0005] Therefore, a limiting device for boring of shaft parts is proposed here. Utility Model Content

[0006] This utility model proposes a limiting device for boring shaft parts, which can make multiple clamping blocks fit against the surface of the workpiece, clamping workpieces of different shapes, increasing the contact area between the clamping blocks and the workpiece, thereby improving the stability of the workpiece during processing.

[0007] This utility model is achieved through the following technical solution: a limiting device for boring shaft parts, including a mounting frame, a clamping hole inside the mounting frame, two support blocks inside the mounting frame, and a power assembly inside the mounting frame to drive the two support blocks to move. The power assembly includes a motor fixed to one side of the mounting frame, output shafts fixed to both output ends of the motor, a conical drive wheel fixedly sleeved at the end of the output shaft away from the motor, a conical driven wheel meshing around the conical drive wheel, a threaded rod fixedly sleeved inside the conical driven wheel, and the threaded rod rotatably sleeved inside the mounting frame, two threads in opposite directions at both ends of the threaded rod, a transmission block threadedly sleeved at both ends of the threaded rod, a connecting plate fixed to one side of the transmission block, and the connecting plate fixed to one side of the support block.

[0008] Furthermore, a first limiting block is rotatably sleeved around the output shaft, and the first limiting block is fixed to one side of the mounting bracket.

[0009] Furthermore, a second limiting block is rotatably sleeved around the outer periphery of the threaded rod, and the second limiting block is fixed to the inner side wall of the mounting bracket.

[0010] Each of the two support blocks has a clamping assembly for fixing the workpiece on one side that is close to each other. The clamping assembly includes a support frame that slides inside the support block. Two connecting frames slide on the side of the support frame away from the support block. Two clamping blocks slide on the side of each connecting frame away from the support frame. An anti-slip pad is fixed on the side of each clamping block away from the connecting frame.

[0011] Furthermore, a first arc-shaped rod is fixed to one side of the support frame near the support block, and the outer surface of the first arc-shaped rod is slidably connected to the inside of the support block.

[0012] Furthermore, a second arc-shaped rod is fixed to one side of the connecting frame near the support frame, and the outer surface of the second arc-shaped rod is slidably connected to the inside of the support frame.

[0013] Furthermore, a third arc-shaped rod is fixed to one side of the clamping block near the connecting frame, and the outer surface of the third arc-shaped rod is slidably connected to the inside of the connecting frame.

[0014] This utility model provides a limiting device for boring shaft parts, which has the following beneficial effects: This boring and positioning device for shaft parts uses a motor to drive two support blocks closer together, simultaneously bringing the clamping block into contact with the workpiece surface. The support blocks then continue to move, using the support blocks and workpiece to press against the clamping block, connecting frame, and support frame. This causes the connecting frame to slide inside the support frame, while the clamping block slides inside the connecting frame, allowing multiple clamping blocks to conform to the workpiece surface. This increases the contact area between the clamping blocks and the workpiece, enabling the clamping of workpieces of different shapes and improving the stability of the workpiece during processing.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0018] Please see Figures 1-4 The present invention proposes the following implementation scheme: a limiting device for boring of shaft parts, including a mounting frame 1, a clamping hole 11 inside the mounting frame 1, two support blocks 2 inside the mounting frame 1, and a power assembly 4 inside the mounting frame 1 for moving the two support blocks 2. The power assembly 4 includes a motor 41 fixed to one side of the mounting frame 1, an output shaft 42 fixed to both output ends of the motor 41, a conical drive wheel 43 fixedly sleeved at the end of the output shaft 42 away from the motor 41, a conical driven wheel 44 meshing around the conical drive wheel 43, a threaded rod 45 fixedly sleeved inside the conical driven wheel 44, and the threaded rod 45 rotatably sleeved inside the mounting frame 1, two threads in opposite directions at both ends of the threaded rod 45, a transmission block 46 threadedly sleeved at both ends of the threaded rod 45, a connecting plate 47 fixed to one side of the transmission block 46, and the connecting plate 47 fixed to one side of the support block 2.

[0019] Please refer to this carefully. Figure 2 The output shaft 42 is rotatably sleeved with a first limiting block 48, and the first limiting block 48 is fixed to one side of the mounting bracket 1.

[0020] The outer periphery of the threaded rod 45 is rotatably sleeved with a second limiting block 49, and the second limiting block 49 is fixed to the inner side wall of the mounting bracket 1.

[0021] In the above scheme, the starting motor 41 drives the output shaft 42 to rotate, and drives the threaded rod 45 to rotate inside the mounting frame 1 through the cone driving wheel 43 and the cone driven wheel 44. The threaded rod 45 and the transmission block 46 are used to move the connecting plate 47 inside the mounting frame 1, so that the two support blocks 2 move closer to each other.

[0022] Please refer to this carefully. Figure 3 and Figure 4 Each of the two support blocks 2 has a clamping assembly 3 for fixing the workpiece on one side that is close to each other. The clamping assembly 3 includes a support frame 31 that slides inside the support block 2. Two connecting frames 32 slide on the side of the support frame 31 away from the support block 2. Two clamping blocks 33 slide on the side of each connecting frame 32 away from the support frame 31. An anti-slip pad 34 is fixed on the side of each clamping block 33 away from the connecting frame 32.

[0023] A first arc-shaped rod 35 is fixed to one side of the support frame 31 near the support block 2, and the outer surface of the first arc-shaped rod 35 is slidably connected to the inside of the support block 2.

[0024] A second arc-shaped rod 36 is fixed to one side of the connecting frame 32 near the support frame 31, and the outer surface of the second arc-shaped rod 36 is slidably connected to the inside of the support frame 31.

[0025] A third arc-shaped rod 37 is fixed on one side of the clamping block 33 near the connecting frame 32, and the outer surface of the third arc-shaped rod 37 is slidably connected to the inside of the connecting frame 32.

[0026] In the above scheme, the support block 2 drives the clamping block 33 to contact the surface of the workpiece at the same time. Then the support block 2 continues to move, and the support block 2 and the workpiece squeeze the clamping block 33, the connecting frame 32 and the support frame 31, so that the connecting frame 32 slides inside the support frame 31, and the clamping block 33 slides inside the connecting frame 32, and so that multiple clamping blocks 33 are in contact with the surface of the workpiece.

[0027] In use, the workpiece to be processed is placed inside the clamping hole 11. The motor 41 is started to drive the output shaft 42 to rotate, and the conical drive wheel 43 and the conical driven wheel 44 drive the threaded rod 45 to rotate inside the mounting frame 1. The threaded rod 45 and the transmission block 46 are used to move the connecting plate 47 inside the mounting frame 1, so that the two support blocks 2 are brought closer to each other, and the clamping block 33 is simultaneously brought into contact with the surface of the workpiece. Then the support blocks 2 continue to move, and the support blocks 2 and the workpiece squeeze the clamping block 33, the connecting frame 32 and the support frame 31, so that the connecting frame 32 slides inside the support frame 31, and the clamping block 33 slides inside the connecting frame 32. Multiple clamping blocks 33 are made to fit against the surface of the workpiece, increasing the contact area between the clamping block 33 and the workpiece. This allows for clamping of workpieces of different shapes, thereby improving the stability of the workpiece during processing.
