[0002] In the field of machining, hole machining of shaft workpieces is a common and important process, widely used in automobile manufacturing, aerospace, precision instruments, and many other industries. With the diversification of industrial production, the specifications and shapes of shaft workpieces are becoming increasingly complex, placing higher demands on machining accuracy and efficiency. However, existing hole machining devices for shaft workpieces have significant shortcomings in adapting to the machining of multi-specification workpieces, making it difficult to meet actual production needs. For example, existing technical solutions still have certain limitations; their clamping mechanisms have limited adjustment ranges, making it difficult to adapt to shaft workpieces of different diameters and lengths, resulting in poor equipment versatility. Furthermore, existing devices often require frequent fixture changes or workpiece position adjustments during machining, increasing operational complexity and making them susceptible to human error, affecting machining accuracy and efficiency. Simultaneously, some devices lack effective limiting and guiding structures, causing workpiece misalignment or vibration during machining, further reducing machining quality. Therefore, developing a device capable of adapting to the machining needs of multi-specification shaft workpieces, possessing high-precision positioning and stable machining capabilities, has become an urgent technical challenge. The present invention aims to overcome the shortcomings of the prior art and provide a device for machining holes in multi-specification shaft workpieces with reasonable structural design, convenient operation and wide applicability, so as to meet the needs of modern industrial production for efficient and precise machining.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] Please see Figures 1 to 4 This utility model provides a device for machining holes in multi-specification shaft-type workpieces, including a worktable 1, a machining mechanism 2, and a limiting mechanism 3. The worktable 1 serves as the basic platform for the entire device, supporting and fixing other components; its surface is precision-machined to ensure flatness and stability. The machining mechanism 2, mounted on the worktable 1, includes a first base 21, a support block 22, a lead screw 23, a drive platform 24, a guide rod 25, a handwheel 26, and a drilling component 27. The limiting mechanism 3 is located on the other side of the worktable 1 and is used for clamping and positioning the shaft-type workpieces.

[0023] The first base 21 is connected to the worktable 1 through multiple threaded holes at its bottom and is securely fixed to the worktable 1 with bolts. The first base 21 provides basic support for the machining mechanism 2 and has internal reinforcing ribs to improve the stability of the overall structure. The support block 22 is fixed to the first base 21 and also has internal reinforcing ribs, further enhancing the overall rigidity of the machining mechanism 2. The lead screw 23 passes through the support block 22 and is connected to the drive table 24. Rotating the lead screw 23 enables the drive table 24 to move linearly in a predetermined direction. Bearing seats are provided at both ends of the lead screw 23, which can effectively reduce friction and improve motion accuracy. Guide rods 25 are installed on both sides of the drive table 24 to guide the drive table 24 to move along a predetermined trajectory. The surface of the guide rods 25 is hardened to extend its service life and ensure smooth guidance. The handwheel 26 is connected to one end of the lead screw 23 and has anti-slip texture on its outer surface, making it easy for the operator to manually control the rotation of the lead screw 23. The drilling component 27 is mounted on the drive table 24 and secured by a quick-release clamp, allowing for rapid replacement of different tool sizes according to machining requirements. The quick-release clamp includes jaws and springs; the jaws clamp the tool using the spring's elasticity, and release can be achieved by pressing a release button. A limiting block 28 is mounted on the drive table 24, with an elastic pad on its lower surface to assist in fixing the workpiece and prevent displacement due to vibration during machining.

[0024] The limiting mechanism 3 is installed on the worktable 1 and includes a second base 301, a fixed base 302, a rotating shaft 303, a rotating handle 304, a left-side clamping seat 305, a clamping block 306, a sliding block 307, a sliding groove 308, anti-slip stripes 309, an adjusting seat 310, a right-side clamping seat 311, an adjusting groove 312, an adjusting rod 313, and a fastening bolt 314. The second base 301 is connected to the worktable 1 through multiple threaded holes at its bottom and is fixed to the worktable 1 using bolts. The fixed base 302 is connected to the second base 301 and has mounting holes inside for installing the rotating shaft 303 and other components. The rotating shaft 303 cooperates with the rotating handle 304, and the clamping block 306 is moved by rotation. Locking nuts are provided at both ends of the rotating shaft 303 to prevent loosening. Left clamping seat 305 and right clamping seat 311 are respectively disposed on both sides of fixed seat 302, and their inner surfaces are provided with V-shaped grooves to accommodate shaft workpieces of different diameters. Clamping block 306 directly contacts the workpiece, and its surface is provided with anti-slip stripes 309, which are made of wear-resistant material and can maintain good anti-slip performance after repeated use. Sliding block 307 is installed in sliding groove 308, the width of sliding groove 308 matching the thickness of sliding block 307, and the movement of sliding block 307 is driven by adjusting rod 313. Adjusting seat 310 is disposed below right clamping seat 311, and its interior is provided with threaded hole for connection with adjusting rod 313. Adjusting rod 313 is connected to adjusting seat 310 through adjusting groove 312, and one end of adjusting rod 313 is provided with handle, which allows the operator to manually adjust the position of right clamping seat 311. The fastening bolt 314 passes through the adjusting seat 310 and engages with the threaded hole on the adjusting rod 313 to lock the position of the adjusting rod 313 and ensure stable clamping.

[0025] Combined with appendix Figures 1 to 4The specific operating principle of the device in this embodiment is as follows: First, the shaft workpiece to be processed is placed on the worktable 1, with one end resting in the V-shaped groove of the left clamping seat 305. By rotating the handle 304, the rotating shaft 303 is driven to rotate, thereby pushing the clamping block 306 closer to the workpiece, initially fixing the workpiece position. Then, the position of the right clamping seat 311 is adjusted. By manually rotating the handle on the adjusting rod 313, the sliding block 307 moves along the slide groove 308, driving the right clamping seat 311 closer to the workpiece. When the V-shaped groove of the right clamping seat 311 contacts the workpiece, the adjusting rod 313 is further fine-tuned until the workpiece is firmly clamped between the left clamping seat 305 and the right clamping seat 311. At this time, the position of the adjusting rod 313 is locked using the fastening bolt 314 to ensure stable clamping. After the workpiece is clamped, the processing mechanism 2 is started. The operator rotates the handwheel 26 to drive the lead screw 23 to rotate, thereby causing the drive table 24 to move smoothly along the direction of the guide rod 25. The drive table 24 moves the drilling part 27 close to the workpiece surface, while the limiting pressure block 28 presses down on the workpiece to help fix its position. When the drilling part 27 reaches the predetermined position, the drilling part 27 is opened for processing. After processing is completed, the handwheel 26 is reversed to return the drive table 24 to the initial position, the fastening bolt 314 is loosened, and the adjusting rod 313 and the handle 304 are rotated in the opposite direction to release the clamping of the workpiece and remove the processed workpiece.

[0026] To accommodate shaft-type workpieces of different specifications, the limiting mechanism 3 in this embodiment is designed with adjustable clamping components. The V-shaped grooves of the left clamping seat 305 and the right clamping seat 311 can accommodate workpieces of various diameters. The anti-slip stripes 309 on the clamping block 306 are made of high-hardness wear-resistant material, ensuring sufficient friction while avoiding damage to the workpiece surface. The slide groove 308 and the adjusting groove 312 are both manufactured using precision machining processes, and their inner surfaces are polished to reduce the coefficient of friction. They are also provided with lubrication channels for periodically injecting lubricating oil to maintain smooth sliding. The handwheel 26 and the handle 304 are both designed with ergonomic shapes, and their outer surfaces are provided with anti-slip grooves, making it easier for operators to apply force and improving operational convenience.

[0027] In this embodiment, the machining mechanism 2, through the design of the lead screw 23 and guide rod 25, ensures the smooth movement and positioning accuracy of the drilled part 27 during machining. The bearing seats at both ends of the lead screw 23 reduce friction and improve the accuracy of movement. The surface hardening treatment of the guide rod 25 extends its service life and ensures the stability of guidance. The quick-release fixture design allows the drilled part 27 to quickly change to different specifications of cutting tools according to machining requirements, significantly improving machining efficiency. The elastic pad of the limiting pressure block 28 effectively prevents the workpiece from shifting due to vibration during machining, further improving machining accuracy.

[0028] In practical applications, the multi-specification shaft workpiece hole machining device provided in this embodiment is suitable for shaft parts machining in the machinery manufacturing industry, especially for the production needs of small and medium-sized enterprises. For example, in automotive parts manufacturing, it is necessary to machine holes in shaft parts of different specifications such as drive shafts and steering shafts. Traditional equipment often requires frequent fixture changes or adjustments to machining parameters, which is complex and inefficient. However, the device in this embodiment, through its flexible clamping mechanism and stable machining system, can complete the machining tasks of multiple specifications of workpieces in a short time, saving time and improving machining quality.

[0029] In summary, the multi-specification shaft workpiece hole machining device in this embodiment achieves a comprehensive improvement in stability, accuracy, and convenience during the shaft workpiece hole machining process through optimized structural design and functional configuration. The device has a compact and reasonable overall structure, with scientifically arranged components, saving space and facilitating maintenance, thus possessing high practical value and market potential. Through the above technical solution, this utility model solves the problems of poor adaptability, complex operation, and insufficient machining accuracy in existing technologies, providing reliable technical support for industrial production.
