Description

Technical Field

[0001] This utility model relates to the field of CNC lathe technology, and in particular to a device for improving the machining stability of a CNC vertical lathe. Background Technology

[0002] The CNC vertical lathe is a high-precision, high-efficiency automated machine tool. Its spindle is perpendicular to the horizontal plane and the worktable is horizontally arranged. It is particularly suitable for machining disc, ring and shell parts with large radial dimensions and small axial dimensions, such as flanges, hubs and propellers.

[0003] A search revealed that CN221019899U discloses a clamping mechanism for a vertical CNC lathe, including a base, the base of which is equipped with a drive motor.

[0004] The clamping mechanism for a vertical CNC lathe described in the prior art, while avoiding excessive metal chips affecting clamping stability through the arrangement of a worktable, air pump, delivery pipe, nozzle, bracket, screw, and movable block, has the drawback that each clamping block is individually controlled by a cylinder, making it difficult to maintain the synchronization of the three clamping blocks.

[0005] Therefore, we propose a device to improve the machining stability of CNC vertical lathes. Utility Model Content

[0006] The present invention aims to solve the technical problems existing in the prior art and provide a device for improving the machining stability of CNC vertical lathes.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a device for improving machining stability of a CNC vertical lathe, comprising a base, a rotating table at the top of the base, a spindle rotatably inserted at the center of the rotating table, a machining table rotatably mounted on the top of the spindle, a protective cylinder fixedly mounted on the top of the machining table, a linkage plate between the machining table and the rotating table, the linkage plate being fixedly fitted onto the spindle, three support rods on the outside of the linkage plate, the bottom of each support rod being fixedly mounted on the top of the rotating table, and the top of each support rod being fixedly mounted on the bottom of the machining table, and guide rails being provided between each pair of support rods. The guide rails are fixedly installed on the top of the rotating table. Each guide rail is slidably mounted with a guide slider. Each guide slider is fixedly mounted with a connecting block on its top. Each connecting block has a linkage rod rotatably mounted on its top end near the linkage plate via a rotating shaft. The other end of each linkage rod is rotatably mounted on the top of the linkage plate off-center via a rotating shaft. Each connecting block has a connecting rod fixedly mounted on its top end away from the linkage plate. Each connecting rod is slidably inserted into a protective cylinder. The other end of each connecting rod is fixedly mounted with a clamping block. A rotary cylinder is fixedly installed at the bottom of the rotating table. The bottom end of the main shaft is mounted on the top output end of the rotary cylinder via a transmission shaft.

[0008] Furthermore, a limiting slide rail is fixedly installed at the top of the inner wall of the base, and the bottom of the side wall of the rotating platform is slidably installed on the limiting slide rail. A transmission worm gear is fixedly fitted at the top of the side wall of the rotating platform, and a secondary shaft is provided on the right side of the transmission worm gear. A transmission worm is fixedly fitted on the secondary shaft, and the transmission worm and the transmission worm gear are meshed and connected.

[0009] Furthermore, mounting plates are provided on the front and rear sides of the transmission worm gear, and each mounting plate is fixedly installed on the top of the base. The two ends of the secondary shaft are respectively rotatably inserted into the front and rear transmission worm gears.

[0010] Furthermore, a drive motor is fixedly mounted on the front of the mounting plate, and the front end of the sub-shaft is mounted on the output end of the drive motor via a transmission shaft.

[0011] Furthermore, the top of the processing table has three vertically connected dust removal ports, and each dust removal port has a drawer frame on its lower side. Each drawer frame is fixedly installed on the bottom of the processing table, and a waste collection drawer is slidably installed on each drawer frame.

[0012] This utility model provides a device for improving the machining stability of a CNC vertical lathe. It has the following features:

[0013] Beneficial effects:

[0014] 1. This device improves the machining stability of a CNC vertical lathe. In use, the workpiece is placed on the top of the machining table, and the rotary cylinder is started to drive the spindle to rotate. The spindle drives the linkage plate to rotate, and the linkage plate drives the linkage rod to rotate around the spindle through the rotating shaft. The linkage rod drives the connecting block to move through the rotating shaft. The connecting block slides along the guide rail to the linkage plate through the guide slider. The connecting block drives the clamping block to clamp the workpiece through the connecting rod. By setting the linkage rod and the linkage plate, the three clamping blocks are driven to move simultaneously, ensuring that the three clamping blocks contact the workpiece at the same time. This avoids the problem of asynchronous clamping caused by air pressure fluctuations or differences in the response of solenoid valves, and improves the clamping stability.

[0015] 2. This device for improving machining stability on a CNC vertical lathe involves clamping a workpiece, starting the drive motor to rotate the secondary shaft, which in turn rotates the transmission worm gear. The transmission worm gear, through a transmission worm wheel, drives the rotary table to rotate along the limit slide rail. The rotary table, through a support rod, drives the machining table to rotate, thereby causing the workpiece mounted on top of the machining table to rotate, facilitating the machining of the workpiece. By setting the transmission worm wheel and transmission worm gear, the rotary table after rotation is locked, effectively improving the practicality of the device.

[0016] 3. This device improves the machining stability of a CNC vertical lathe. After machining, the rotary cylinder is started to reverse and remove the part. The debris is swept into the waste collection drawer through the dust removal port. After the waste collection drawer is full, it slides out from the outer frame of the drawer to facilitate the collection of debris and centralized processing, which further improves the practicality of the device.

The bottom of each support rod 23 is fixedly mounted on the top of the rotating platform 9, and the top of each support rod 23 is fixedly mounted on the bottom of the machining table 6. Guides are provided between each pair of support rods 23. Each guide rail 3 is fixedly mounted on the top of the rotating table 9. A guide slider 20 is slidably mounted on each guide rail 3. A connecting block 2 is fixedly mounted on the top of each guide slider 20. A linkage rod 11 is rotatably mounted on the top of each connecting block 2 near the linkage disc 12 via a rotating shaft. The other end of each linkage rod 11 is rotatably mounted on the top of the linkage disc 12 off-center via a rotating shaft. A connecting rod 4 is fixedly mounted on the top of each connecting block 2 away from the linkage disc 12. Each connecting rod 4 is slidably inserted into the protective cylinder 8. The other end of the connecting rod 4 is fixedly installed with a clamping block 5. A rotary cylinder 19 is fixedly installed at the bottom of the rotating table 9. The bottom end of the main shaft 10 is installed at the top output end of the rotary cylinder 19 via a transmission shaft. A limit slide rail 18 is fixedly installed at the top of the inner wall of the base 1. The bottom end of the side wall of the rotating table 9 is slidably installed on the limit slide rail 18. A transmission worm gear 14 is fixedly fitted at the top of the side wall of the rotating table 9. A secondary shaft 16 is provided on the right side of the transmission worm gear 14. A transmission worm 15 is fixedly fitted on the secondary shaft 16. The transmission worm 15 and the transmission worm gear 14 are meshed and connected. The transmission worm 15 is connected to the front and rear sides. Each mounting plate 13 is fixedly installed on the top of the base 1. The two ends of the sub-shaft 16 are respectively rotatably inserted into the front and rear transmission worm gears 14. The front of the front mounting plate 13 is fixedly installed with a drive motor 17. The front end of the sub-shaft 16 is installed at the output end of the drive motor 17 through the transmission shaft.

Each drawer frame 21 is fixedly installed at the bottom of the processing table 6. Each drawer frame 21 has a waste collection drawer 22 that is slidably installed on it.

[0029] The working principle of this utility model is as follows: When using this device, the part is placed on the top of the processing table 6. The rotary cylinder 19 is started to drive the spindle 10 to rotate. The spindle 10 drives the linkage plate 12 to rotate. The linkage plate 12 drives the linkage rod 11 to rotate around the spindle 10 through the rotating shaft. The linkage rod 11 drives the connecting block 2 to move through the rotating shaft. The connecting block 2 slides along the guide rail 3 through the guide slider 20 toward the linkage plate 12. The connecting block 2 drives the clamping block 5 to clamp the part through the connecting rod 4. By setting the linkage rod 11 and the linkage plate 12, the three clamping blocks 5 are driven to move simultaneously, ensuring that the three clamping blocks 5 contact the part at the same time. This avoids the problem of asynchronous clamping caused by air pressure fluctuations or differences in the response of the solenoid valve, and improves the clamping stability.

[0030] After clamping the part, the drive motor 17 is started to drive the secondary shaft 16 to rotate. The secondary shaft 16 drives the transmission worm gear 15 to rotate. The transmission worm gear 15 drives the rotating table 9 to rotate along the limit slide rail 18 through the transmission worm wheel 14. The rotating table 9 drives the processing table 6 to rotate through the support rod 23, thereby driving the part set on the top of the processing table 6 to rotate, which facilitates the processing of the part. By setting the transmission worm wheel 14 and the transmission worm gear 15, the rotating table 9 after rotation is locked, which effectively improves the practicality of the device.

[0031] After processing, the rotary cylinder 19 is started to reverse and remove the parts. The debris is swept into the waste collection drawer 22 through the dust removal port 7. After the waste collection drawer 22 is full, it slides out from the drawer frame 21 to facilitate the collection of debris and centralized processing, which further improves the practicality of the device.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
