Description

Technical Field

[0001] This utility model relates to the field of large CNC vertical lathe technology, specifically a large CNC vertical lathe boring fixture. Background Technology

[0002] A boring machine is a machine tool that primarily uses a boring bar to bore pre-drilled holes in a workpiece. Typically, the rotation of the boring bar is the main motion, while the movement of the boring bar or workpiece is the feed motion. It is mainly used for machining high-precision holes or for finishing multiple holes in a single positioning operation. Using different tools and accessories, it can also perform drilling, milling, and cutting operations with higher precision and surface finish than drilling machines. To ensure the stability and precision of large workpieces (such as discs or boxes) during high-speed boring, a large CNC vertical lathe boring fixture is required.

[0003] The existing patent, CN214109570U, entitled "A Large CNC Vertical Lathe Boring Fixture," discloses a large CNC vertical lathe boring fixture, including a chassis. The chassis surface is provided with four first electric telescopic rods. A first fixing block is provided at the top of each first electric telescopic rod. A second electric telescopic rod is provided on the first fixing block, and a second fixing block is provided at the end of each second electric telescopic rod. A base plate is provided on the second fixing block, and an arc plate is provided on the base plate. An arc plate is provided on the edge of the base plate. The arc plate includes an upper horizontal portion and a lower curved portion. A second spring is provided on the inner surface of the lower curved portion of the arc plate, and a buffer plate is provided at the other end of the second spring. The chassis is provided with four buffer mechanisms. When the first and second electric telescopic rods operate, the disc-shaped workpiece is clamped by the arc plate and the buffer plate, and the disc-shaped workpiece is limited and fixed, facilitating the installation of the disc-shaped workpiece. The horizontal and vertical forces acting on the disc-shaped workpiece are buffered by the second and first springs, ensuring the stability of the disc-shaped workpiece.

[0004] The above-mentioned device operates with the first and second electric telescopic rods, and the disc workpiece is clamped by the arc plate and the buffer plate. The disc workpiece is limited and fixed, which facilitates the installation of the disc workpiece. However, the circular workpiece usually needs to rotate itself during processing, and the workpiece's central axis needs to coincide with the rotation central axis. Otherwise, it is easy to increase the error and cannot meet people's needs. In view of the above situation, technical innovation is carried out on the basis of the existing boring fixture. Utility Model Content

[0005] The purpose of this utility model is to provide a large CNC vertical lathe boring fixture to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a large CNC vertical lathe boring fixture, comprising a platform and a middle bevel gear, a rotating seat is installed below the platform and the rotating seat is rotatably connected to the platform, the middle bevel gear is installed in the inner middle of the platform, and a side bevel gear is installed above the middle bevel gear, a lead screw is installed on one side of the side bevel gear, and a moving block is threadedly connected to the outer periphery of the lead screw, and a workpiece is disposed in the upper middle part of the moving block.

[0007] Furthermore, an inner clamping block is installed on the upper left side of the moving block, and an outer clamping block is provided on one side of the inner clamping block. The side bevel gear drives the lead screw to rotate, and the rotation of the lead screw drives the moving block to move. The inner clamping block on the moving block abuts against the inner side of the workpiece.

[0008] Furthermore, a second lead screw is installed inside the outer clamping block, and the second lead screw is threadedly connected to the outer clamping block. The rotation of the second lead screw causes the outer clamping block to abut against the outside of the workpiece, which facilitates the installation and fixing of the workpiece.

[0009] Furthermore, a bevel gear set is installed at one end of the lead screw two, and an internal hexagon block is installed above the bevel gear set. The internal hexagon block is rotated by a hex wrench, thereby driving the lead screw two to rotate through the bevel gear set.

[0010] Furthermore, a level is installed on the upper left side of the platform, and the level is embedded in the platform, making it easy to level.

[0011] Furthermore, a motor is installed in the lower center of the rotating seat, and a support component is provided on the outside of the motor. The motor drives the side bevel gear to rotate through the middle bevel gear.

[0012] Furthermore, the support assembly includes a stud, a screw block, and a support leg. The lower end of the stud is threadedly connected to the screw block, and the support leg is rotatably connected to the lower part of the screw block. Rotating the screw block changes the length of the stud within the stud, thereby changing the support height of the support leg, which facilitates leveling the device according to a spirit level.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When the workpiece is placed on the platform, the motor drives the side bevel gear to rotate through the middle bevel gear, the side bevel gear drives the lead screw to rotate, the lead screw rotates and drives the moving block to move. The inner clamping block on the moving block abuts against the inner side of the workpiece. The hexagonal wrench drives the inner hexagonal block to rotate, thereby driving the lead screw to rotate through the bevel gear set. The lead screw rotates and drives the outer clamping block to abut against the outer side of the workpiece, which is convenient for installing and fixing the workpiece. At the same time, it can adaptively align the central axis of the workpiece with the central axis of the platform, which is convenient for rotational processing. The rotating screw block changes the length of the stud in the stud, thereby changing the support height of the support foot, which makes it easy to level the device according to the level. The platform rotates more smoothly on the rotating seat, improving the processing accuracy of the workpiece.

[0014] 1. This utility model places the workpiece on a platform. The motor drives the side bevel gear to rotate through the middle bevel gear. The side bevel gear drives the lead screw to rotate. The rotation of the lead screw drives the moving block to move. The inner clamping block on the moving block abuts against the inner side of the workpiece.

A bevel gear set 9 is installed at one end, and an internal hexagon block 10 is installed above the bevel gear set 9. When the workpiece 11 is placed on the platform 1, the motor 14 drives the side bevel gear 3 to rotate through the middle bevel gear 2. The side bevel gear 3 drives the lead screw 4 to rotate. The rotation of the lead screw 4 drives the moving block 5 to move. The inner clamping block 6 on the moving block 5 abuts against the inner side of the workpiece 11. The internal hexagon block 10 is driven to rotate through the hexagon wrench, thereby driving the lead screw 8 to rotate through the bevel gear set 9.
