Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a lathe processing fixture for a vortex special-shaped workpiece. Background Art

[0002] Machining refers to the process of changing the shape, size or performance of a workpiece through a mechanical device. It can be divided into cutting and pressure processing according to the difference in processing methods.

[0003] The utility model with the existing authorized application number CN214489792U discloses a fixture for processing a scroll disk, which includes a base, an inner supporting device and an outer holding device. The inner supporting device and the outer holding device are coaxially installed on the base. The workpiece mounting position is set on the upper end surface of the base and is located between the inner supporting device and the outer holding device. The inner supporting device and the outer holding device clamp the scroll disk workpiece from the inner and outer directions respectively.

[0004] By adopting the above technical solution, the utility model adopts the form of inner support and outer embrace to clamp and position the scroll disk from both the inside and the outside. The clamping force is uniform, which can effectively reduce the deformation of the scroll profile of the scroll disk. However, in the above technical solution, the clamping block is prone to damage during long-term use. When the surface of the clamping block is damaged, there will be edges on the surface, which will easily cause wear to the workpiece during subsequent clamping. It is more troublesome for the staff to replace it, which leads to the problem of low practicality. Utility Model Content

[0027] See also Figure 1-5 The utility model discloses a lathe processing fixture for a vortex special-shaped workpiece, comprising a limit plate 1, a support frame 2 and a rotating disk 3. The outer surface of the rotating disk 3 is rotatably connected to the inner wall of the support frame 2. Two fixing blocks 5 are fixedly connected to both side surfaces of the limit plate 1. A pulling block 4 is fixedly connected to the left side of the support frame 2. By setting the fixing block 5, a fixed platform can be provided for the device, which is convenient for the staff to fix. By setting the pulling block 4, the staff can pull the supporting frame 2 to move by the pulling block 4, which is convenient for adjusting the position of the supporting frame 2.

[0028] Three moving blocks 9 are slidably connected to the inner wall of the rotating disk 3, and the upper surface of each fixed block 5 is threadedly connected to a bolt 6. The bottom end of each bolt 6 passes through the fixed block 5 and extends to the bottom of the fixed block 5. By setting the bolt 6, the device can be quickly and firmly fixed to avoid position displacement during use.

[0029] Each moving block 9 is fixedly connected to two sliders 11 on one side close to the rotating disk 3, and two limit blocks 7 are fixedly connected to the bottom surface of the support frame 2. The outer surface of each limit block 7 is slidably connected to the inner wall of the limit plate 1. By setting the limit blocks 7, the support frame 2 can be easily connected and fixed to the limit plate 1, which is convenient for the staff to use.

[0030] The outer surface of each group of sliders 11 is slidably connected to a clamping block 10, and the outer surface of each clamping block 10 is slidably connected to the inner wall of the rotating disk 3. The bottom surface of the rotating disk 3 is fixedly connected to a rotating motor 8, and the bottom surface of the rotating motor 8 is fixedly connected to the inner bottom wall of the support frame 2. By setting up the rotating motor 8, the power required for rotation can be provided, thereby facilitating the adjustment of the angle of the workpiece.

[0031] The upper surface of each clamping block 10 and the upper surface of the moving block 9 are fixedly connected to two support columns 12, the outer surface of each group of support columns 12 is slidably connected to a support plate 18, the inner wall of the rotating disk 3 is fixedly connected to an electric telescopic rod 13, and the telescopic end of each electric telescopic rod 13 is fixedly connected to the outer surface of the moving block 9. By setting the electric telescopic rod 13, it is easy to drive the clamping block 10 to move, thereby quickly clamping and fixing the workpiece.

[0032] The inner wall of each support plate 18 is threadedly connected to a threaded rod 14, the bottom end of each threaded rod 14 is fixedly connected to a bearing 19, and the top of each support column 12 is threadedly connected to a nut 17, and the bottom surface of each nut 17 is in contact with the upper surface of the support plate 18. By setting the nut 17, the support plate 18 can be squeezed and fixed firmly to avoid falling off during use.

[0033] The outer ring of each bearing 19 is fixedly connected to an extrusion plate 20, the inner wall of each extrusion plate 20 is slidably connected to the outer surface of the support column 12, the upper surface of the threaded rod 14 is fixedly connected to a handle 16, and the outer surface of the handle 16 is fixedly connected to an anti-slip pad 15. By providing the handle 16 and the anti-slip pad 15, it is convenient for the staff to drive the threaded rod 14 to rotate through the handle 16, and it is also convenient to disassemble the support plate 18.

[0034] The working principle of the present invention is as follows: first, the staff transports the device to a suitable position for use, and then turns on the power of the electric telescopic rod 13 and the rotating motor 8, so that they can be in a stable power-on state to avoid power outages during use. Then, when processing the workpiece, the staff first places the workpiece to be processed on the rotating disk 3, and then turns on the electric telescopic rod 13. The electric telescopic rod 13 can generate power and extend or shorten. The electric telescopic rod 13 can drive the moving block 9 and the clamping block 10 to move until the workpiece is clamped and fixed firmly. At the same time, the rotating motor 8 is turned on. After the rotating motor 8 is turned on, it starts to rotate. The rotating motor 8 can drive the rotating disk 3 and the workpiece to rotate, so that the equipment can be coordinated and processed. When processing the workpiece, when the clamping block 10 is damaged and needs to be replaced, the staff first removes the nut 17 on the support column 12, and disassembles the extrusion plate 20 and the support plate 18 through the threaded rod 14. After the extrusion plate 20 and the support plate 18 are disassembled, the damaged clamping block 10 is removed, and then the new clamping block 10 is placed on the moving block 9 through the slider 11, and then the threaded rod 14 is rotated. The threaded rod 14 can move downward, so that under the action of the movement of the threaded rod 14, the bearing 19 and the extrusion plate 20 will be driven to move until they are moved to the appropriate position and then squeezed and fixed. The replacement work of the clamping block 10 can be completed, thereby effectively avoiding the situation where it is difficult to replace the clamping block 10 when it is damaged.
