Description

Technical Field

[0001] This utility model relates to a vertical machining center, specifically a vertical machining center for gear processing that facilitates material loading, and belongs to the technical field of gear processing equipment. Background Technology

[0002] Gears are key basic components in the mechanical field for realizing power transmission and motion conversion. Through tooth surface meshing, they transmit the rotational motion and torque of the driving shaft to the driven shaft. They are widely used in core scenarios such as automotive transmissions, machine tool spindles, engineering machinery transmission systems, and aerospace equipment. The tooth profile accuracy, surface roughness, and dimensional consistency of gears directly determine the transmission efficiency, operating noise, and service life of mechanical equipment. Vertical machining centers, with their spindles and worktables arranged vertically and equipped with precisely movable worktables, can stably achieve the milling and shaping of gear teeth and the machining of hole systems. Moreover, the equipment has a compact structure, small footprint, and convenient operation and maintenance.

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.

[0025] Please see Figures 1-7 As shown, a vertical machining center for gear processing with convenient loading includes a machining body 1, a cross slide 6 mounted on the machining body 1, a three-jaw chuck 7 mounted on the cross slide 6, a loading structure 2 on the machining body 1, the loading structure 2 including a mounting shaft 201, the mounting shaft 201 being rotatably connected to the machining body 1, a mounting frame 202 being fixedly connected to the mounting shaft 201, two clamping plates 203 being slidably connected to the mounting frame 202, a first lead screw 204 being rotatably connected to the mounting frame 202, the clamping plates 203 being threadedly connected to the first lead screw 204, the threads at both ends of the first lead screw 204 having opposite directions, a sliding frame 208 being slidably connected to the machining body 1, the mounting shaft 201 being rotatably connected to the sliding frame 208, and a storage structure 3 for storing gears on the machining body 1.

[0026] As a technical optimization of this utility model, a rubber pad 205 is fixedly connected to the clamping plate 203, a protective cover 206 is fixedly connected to the mounting frame 202, the clamping plate 203 and the protective cover 206 are slidably connected, a guide shaft 211 is fixedly connected to the processing machine body 1, the sliding frame 208 is slidably connected to the guide shaft 211, a first driving member 207 is installed on the mounting frame 202, the first lead screw 204 is driven by the first driving member 207, a second driving member 209 is installed on the sliding frame 208, the mounting shaft 201 is driven by the second driving member 209, a third driving member 210 is installed on the processing machine body 1, the sliding frame 208 is driven by the third driving member 210, and the storage structure 3 includes a storage cart 301, the storage cart 301 is detachably connected to the processing machine body 1. 1. A slider 302 is slidably connected to the storage cart 301, and a lifting plate 303 is fixedly connected to the slider 302. The lifting plate 303 is slidably connected to the storage cart 301. Next, in preparation for loading, the fourth drive unit 305 (preferably a motor) on the storage cart 301 is started and powered by the power supply 306. The fourth drive unit 305 drives the second lead screw 304 to rotate. When the second lead screw 304 rotates, it drives the slider 302 through the thread to drive the lifting plate 303 to move up and down along the storage cart 301, lifting the gear workpiece stored in the storage cart 301 to a certain height. There is no need to manually move the stacked gear workpieces, reducing the labor intensity in the early stage of loading. Then, the third drive unit 210 (preferably a hydraulic rod) on the processing machine body 1 is started. The third drive unit 210 drives the... The sliding frame 208 slides along the processing machine body 1 and simultaneously slides along the guide shaft 211. The guide shaft 211 ensures that the sliding frame 208 does not deviate during sliding, improving the loading position accuracy. This causes the mounting shaft 201 to drive the mounting frame 202 to move to the gear of the storage cart 301. Then, the first driving component 207 (preferably a motor) on the mounting frame 202 is activated. The first driving component 207 drives the first lead screw 204 to rotate. When the first lead screw 204 rotates, it drives the two clamping plates 203 to move towards each other through the thread, so that the two clamping plates 203 move closer to each other to clamp the gear workpiece. The rubber pads 205 on the inner side of the clamping plates 203 can increase the friction with the gear workpiece, preventing the workpiece from sliding during clamping and preventing the clamping plates 203 from directly contacting the workpiece and causing surface scratches, thus protecting the workpiece. The machining accuracy of the gear workpiece is important. The protective cover 206 on the mounting frame 202 can block dust or machining debris during the movement of the clamping plate 203, preventing impurities from entering the sliding gap between the clamping plate 203 and the mounting frame 202, ensuring smooth sliding of the clamping plate 203 and extending its service life. After clamping the gear, the second drive component 209 (preferably a motor) on the slide frame 208 is activated. The second drive component 209 drives the mounting shaft 201 to rotate, which in turn drives the mounting frame 202 and the clamped gear workpiece to rotate directly above the three-jaw chuck 7 of the cross slide table 6. Then, the position of the slide frame 208 is finely adjusted by the third drive component 210 so that the gear workpiece is aligned with the three-jaw chuck 7. Subsequently, the first drive component 207 drives the clamping plate 203 to release the workpiece, and the workpiece falls into the three-jaw chuck 7.The three-jaw chuck 7 clamps the workpiece to complete the loading. Two opposing sliding clamping plates 203, in conjunction with the storage structure 3, facilitate automated loading and unloading. This not only improves loading efficiency but also avoids workpiece positioning deviations caused by human error, ensuring subsequent processing accuracy. A second lead screw 304 is rotatably connected to the storage carriage 301, and a slider 302 is threadedly connected to the second lead screw 304. A fourth driving component 305 is installed on the storage carriage 301, driving the second lead screw 304. A power supply 306 is also installed on the storage carriage 301.

[0027] As a technical optimization of this utility model, the storage cart 301 is mounted on the processing machine body 1 via an installation structure 4. The installation structure 4 includes a positioning rod 401, which is fixedly connected to the processing machine body 1. A fixing sleeve 402 is fixedly connected to the storage cart 301. The positioning rod 401 and the fixing sleeve 402 are slidably connected. An installation block 403 is slidably connected to the fixing sleeve 402. Before gear processing, the storage cart 301 is first assembled with the processing machine body 1. The operator pulls the pull plate 405, which drives the installation block 403 to slide along the fixing sleeve 402 via the connecting rod 404, while simultaneously stretching the tension spring 406. At this time, the fixing sleeve 402 on the storage cart 301 is... Align the positioning rod 401 on the processing machine body 1 and insert it. Release the pull plate 405, and the tension spring 406 will reset and push the mounting block 403 to engage with the positioning rod 401, thus completing the quick positioning and installation of the storage cart 301. The storage cart 301 can be disassembled and assembled without the aid of tools, which not only improves the docking efficiency between the storage cart 301 and the processing machine body 1, but also facilitates the replacement of the storage cart 301 after it is full. The mounting block 403 engages with the positioning rod 401. A connecting rod 404 is fixedly connected to the mounting block 403. The connecting rod 404 is slidably connected to the fixing sleeve 402. A pull plate 405 is fixedly connected to the connecting rod 404. A tension spring 406 is fixedly connected between the pull plate 405 and the fixing sleeve 402.

[0028] As a technical optimization of this utility model, the processing machine body 1 is provided with a protective structure 5, which includes a rotating shaft 501. The rotating shaft 501 is rotatably connected to the processing machine body 1. During the processing, when the sliding frame 208 drives the gear to move to the loading position, the sliding frame 208 drives the roller 505 to slide along the straight groove 503 of the rotating shaft 501 through the mounting plate 506. At this time, the protective door 502 remains open. When the sliding frame 208 drives the roller 505 into the spiral groove 504 of the rotating shaft 501, the sliding frame 208 continues to move, driving the roller 505 to roll along the spiral groove 504, thereby pushing the rotating shaft 501 to rotate. When the protective door 502 is closed, the processing area is sealed off. The opening and closing of the protective door 502 is controlled synchronously by the movement of the sliding frame 208, without the need for additional drive components. This ensures the safety of operators during processing, prevents injury from flying processing debris, reduces air circulation between the processing area and the outside, lowers the probability of dust entering the processing area, and ensures a clean processing environment. The protective door 502 is fixedly connected to the rotating shaft 501. The rotating shaft 501 is provided with a straight groove 503 and a spiral groove 504. A roller 505 is rotatably connected to the rotating shaft 501, and a mounting plate 506 is rotatably connected to the roller 505. The mounting plate 506 is fixedly connected to the sliding frame 208.

[0029] In use, before gear processing, the storage cart 301 is first assembled with the processing machine body 1. The operator pulls the pull plate 405, which, through the connecting rod 404, drives the mounting block 403 to slide along the fixing sleeve 402, simultaneously stretching the tension spring 406. At this time, the fixing sleeve 402 on the storage cart 301 is aligned with the positioning rod 401 on the processing machine body 1 and fitted onto it. Releasing the pull plate 405 causes the tension spring 406 to reset, pushing the mounting block 403 to engage with the positioning rod 401, thus completing the rapid positioning and installation of the storage cart 301. The storage cart 301 can be disassembled and assembled without tools, improving the docking efficiency between the storage cart 301 and the processing machine body 1, and facilitating subsequent replacement of the storage cart 301 when it is full, meeting the material replenishment needs of batch processing. To prepare for loading, the fourth drive unit 305 (preferably a motor) on the storage cart 301 is started, powered by the power supply 306. The fourth drive unit 305 drives the second lead screw 304 to rotate. When the second lead screw 304 rotates, it drives the slider 302 via the thread to move the lifting plate 303 up and down along the storage cart 301, lifting the gear workpieces stored in the storage cart 301 to a certain height. This eliminates the need for manual handling of the stacked gear workpieces, reducing the labor intensity in the early stages of loading. Subsequently, the third drive unit 210 (preferably a hydraulic rod) on the processing machine body 1 is started. The third drive unit 210 drives the sliding frame 208 to slide along the processing machine body 1. The sliding frame 208 also slides along the guide shaft 211. The guide shaft 211 ensures that the sliding frame 208 does not deviate during sliding, raising the loading position. To ensure precision, the mounting shaft 201 moves the mounting frame 202 to the gear position on the storage cart 301. Then, the first drive unit 207 (preferably a motor) on the mounting frame 202 is activated. The first drive unit 207 drives the first lead screw 204 to rotate. When the first lead screw 204 rotates, it drives two clamping plates 203 to move towards each other via a thread, bringing the two clamping plates 203 closer together to clamp the gear workpiece. The rubber pads 205 on the inner side of the clamping plates 203 increase the friction with the gear workpiece, preventing the workpiece from slipping during clamping and preventing direct contact between the clamping plates 203 and the workpiece, thus protecting the machining precision of the gear workpiece. Meanwhile, the protective cover 206 on the mounting frame 202 can shield the clamping plates 203 from dust or machining debris during movement, preventing impurities from entering the clamping plates 203. The sliding clearance between the 3 and the mounting frame 202 ensures smooth sliding of the clamping plate 203 and extends its service life. After clamping the gear, the second drive component 209 (preferably a motor) on the sliding frame 208 is activated. The second drive component 209 drives the mounting shaft 201 to rotate, which in turn drives the mounting frame 202 and the clamped gear workpiece to rotate directly above the three-jaw chuck 7 of the cross slide table 6. Then, the third drive component 210 finely adjusts the position of the sliding frame 208 so that the gear workpiece is aligned with the three-jaw chuck 7. Subsequently, the first drive component 207 drives the clamping plate 203 to release the workpiece, and the workpiece falls into the three-jaw chuck 7. The three-jaw chuck 7 clamps the workpiece to complete the loading. The two opposing sliding clamping plates 203, in conjunction with the storage structure 3, facilitate automatic handling and loading, which not only improves loading efficiency.This design also avoids workpiece positioning deviations caused by human error, ensuring subsequent processing accuracy. After the workpiece is clamped, it enters the processing stage, and the cross slide 6 begins to work. The cross slide 6 consists of a transverse guide rail, a longitudinal guide rail, and a servo motor. The servo motor drives the transverse sliding block of the cross slide 6 to move along the transverse guide rail and the longitudinal sliding block to move along the longitudinal guide rail, respectively. Because the three-jaw chuck 7 is mounted on the worktable of the cross slide 6, the cross slide 6 can drive the workpiece to achieve precise forward and backward (longitudinal) and left and right (lateral) movements. It works in conjunction with the spindle assembly on the machining body 1 to complete milling, drilling, and other processes of gears. Moreover, the servo drive and lead screw transmission structure of the cross slide 6 can achieve millimeter-level movement accuracy, ensuring that the dimensional accuracy of gear processing meets the requirements. At the same time, the workpiece position can be flexibly adjusted according to the processing requirements, meeting the needs of multi-process integrated gear processing. In the processing, when the sliding frame 208 moves the gear to the loading position, the sliding frame 208 drives the roller 505 to slide along the straight groove 503 of the rotating shaft 501 via the mounting plate 506. At this time, the protective door 502 remains open. When the sliding frame 208 drives the roller 505 into the spiral groove 504 of the rotating shaft 501, the sliding frame 208 continues to move, causing the roller 505 to roll along the spiral groove 504, thereby pushing the rotating shaft 501 to rotate. The rotating shaft 501 then drives the protective door 502 to close, sealing the processing area. The movement of the sliding frame 208 synchronously controls the opening and closing of the protective door 502, eliminating the need for additional drive components. This ensures the safety of operators during processing, prevents injury from flying processing debris, reduces airflow between the processing area and the outside, lowers the probability of dust entering the processing area, and ensures a clean processing environment.
