Description

Technical Field

[0001] This utility model relates to the field of workpiece clamping technology for vertical lathes, specifically a workpiece clamping adjustment mechanism for vertical lathes. Background Technology

[0002] Vertical lathes are large mechanical equipment used to process large and heavy workpieces with large radial dimensions and relatively small axial dimensions and complex shapes.

[0003] However, existing vertical lathe workpiece clamping mechanisms can only clamp workpieces of one size, resulting in low versatility. Furthermore, multiple cylinders are required to clamp workpieces at multiple points, leading to low manufacturing costs.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing workpiece clamping mechanism of vertical lathes. Utility Model Content

[0005] The purpose of this utility model is to provide a vertical lathe workpiece clamping and adjustment mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a vertical lathe workpiece clamping and adjusting mechanism, including a base, a platform fixed to the top side of the base by a support column, a cylinder fixed at the center of the top of the base, the top of the cylinder being fixedly connected to the center of the bottom of a disc, a first through groove being provided inside the disc, a vertical rod being slidably installed inside the first through groove, an anti-detachment plate being fixed at the lower end of the vertical rod, a nut being threaded onto the outer side of the vertical rod above the disc, a second through groove being provided on the platform, a fixing block being fixed through the upper end of the vertical rod and inside the second through groove, and a clamping block being fixed to the side of the fixing block.

[0007] Preferably, the central axis of the cylinder coincides with the central axis of the disk.

[0008] Preferably, the top of the anti-detachment plate is in contact with the bottom of the disc.

[0009] Preferably, the bottom of the nut fits into the top of the disc.

[0010] Preferably, the vertical rod and the second through groove are slidably connected.

[0011] Preferably, the first through slot, the vertical rod, the anti-detachment plate, the nut, the second through slot, the fixing block and the clamping block are all distributed at equal angles about the central axis of the disc and the platform, and the clamping block is designed with a "U" shaped structure, and the two ends of the clamping block are located above the surface of the platform.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The vertical lathe workpiece clamping and adjusting mechanism can move inside the first and second through slots via a vertical rod, thereby adjusting the distance between the left and right clamping blocks and the distance between the front and rear clamping blocks. The positions of the vertical rod and the clamping blocks after movement can be fixed by the threaded connection between the nut and the vertical rod, allowing the four clamping blocks to adjust their positions according to the size of the workpiece, thus enabling the fixing of workpieces of different sizes. By activating a cylinder, the four clamping blocks can be moved downwards simultaneously to fix the workpiece, thereby reducing the number of cylinders and lowering the manufacturing cost of the clamping mechanism. The clamping blocks are designed with a "U" shape, and both ends of the clamping blocks are located above the surface of the table, ensuring that the position of the ends of the clamping blocks pressing on the workpiece is on the surface of the table, not above the second through slot, improving the stability of the workpiece after fixing and preventing the workpiece from being deformed.

[0019] 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.

[0020] Please see Figure 1-5This utility model provides a technical solution: a vertical lathe workpiece clamping and adjusting mechanism, including a base 1, a platform 3 fixed to the top side of the base 1 by a support column 2, a cylinder 4 fixed at the center of the top of the base 1, the top of the cylinder 4 fixedly connected to the center of the bottom of the disc 5, a first through groove 6 opened inside the disc 5, a vertical rod 7 slidably installed inside the first through groove 6, an anti-detachment plate 8 fixed at the lower end of the vertical rod 7, a nut 9 threaded on the outer side of the vertical rod 7 above the disc 5, a second through groove 10 opened on the platform 3, a fixing block 11 fixed through the upper end of the vertical rod 7 through the second through groove 10, a clamping block 12 fixed on the side of the fixing block 11, and the central axis of the cylinder 4 coincides with the central axis of the disc 5.

[0021] The top of the anti-detachment plate 8 fits into the bottom of the disc 5, ensuring that the anti-detachment plate 8 can move at the bottom of the disc 5.

[0022] The bottom of nut 9 fits into the top of disk 5, ensuring that nut 9 can move on the top of disk 5.

[0023] The vertical rod 7 and the second through groove 10 form a sliding connection, which ensures that the vertical rod 7 can move inside the second through groove 10.

[0024] The first through groove 6, vertical rod 7, anti-detachment plate 8, nut 9, second through groove 10, fixing block 11, and clamping block 12 are all distributed at equal angles about the central axis of the disc 5 and the platform 3. The clamping block 12 is designed with a "U" shape, and both ends of the clamping block 12 are located above the surface of the platform 3. This ensures that when the disc 5 moves downward, it can drive the four clamping blocks 12 to move downward at the same time, completing the simultaneous fixation of the workpiece in four places. It also ensures that the end of the clamping block 12 is pressed on the workpiece at the surface of the platform 3, not above the second through groove 10, which improves the stability of the workpiece after fixation and avoids the workpiece being deformed by pressure.

[0025] Working principle: When using the workpiece clamping and adjusting mechanism of this vertical lathe, first place the workpiece on the top of the table 3 and between the four vertical rods 7. Then push the vertical rods 7, which will drive the anti-slip plate 8, nut 9, fixing block 11 and clamping block 12 to move simultaneously until the bottom of the four clamping blocks 12 are all above the workpiece. Then use a wrench to fix the anti-slip plate 8 and use another wrench to rotate the nut 9 to fix the positions of the vertical rods 7, fixing block 11 and clamping block 12. Then start the cylinder 4, which will drive the disc 5, the four vertical rods 7 and the four clamping blocks 12 to move downwards simultaneously, completing the fixation of the top four parts of the workpiece. Since the vertical rods 7 can move inside the first through groove 6 and the second through groove 10, the distance between the clamping blocks 12 can be adjusted, so that the four clamping blocks 12 can fix workpieces of different sizes.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
