Description

Technical Field

[0001] The utility model relates to the technical field of milling equipment, in particular to a milling machine used for milling titanium ingots. Background Art

[0002] As an important engineering material, titanium ingots are widely used in aerospace, medical, chemical and other fields due to their high strength, low density and excellent corrosion resistance. However, the processing of titanium ingots, especially their multi-faceted milling process, has always been a technical challenge in the manufacturing industry. Traditional milling equipment often finds it difficult to achieve efficient and precise multi-faceted milling of titanium ingots, which limits the application range and processing efficiency of titanium ingots.

[0003] Traditional milling equipment usually uses universal tools for single-axis milling. This method requires frequent tool replacement and workpiece adjustment when processing multi-faceted milling, resulting in low processing efficiency and difficulty in ensuring milling accuracy and consistency. Moreover, when cutting large-volume titanium ingots, multiple reciprocating cuts are required to cover the entire area. The main reason for this operation is that the cutter head does not cover enough area, and there is a cutter gap between two cuts. The cutter gap needs to be polished separately, resulting in low overall milling efficiency. Utility Model Content

[0004] The utility model aims to overcome the deficiencies in the prior art and provide a titanium ingot eight-sided milling machine which can perform multi-sided cutting and does not produce seams when milling large-volume titanium ingots.

[0005] The utility model is realized by the following technical scheme: a titanium ingot eight-sided milling machine, comprising a conveying device and a milling assembly arranged above the conveying device, the conveying device comprising a guide rail, and a working table for driving the titanium ingot to move is slidably arranged on the guide rail;

[0009] Furthermore, both sides of the main milling cutter disc are provided with milling chip collection grooves located outside the workbench, the outside of the main milling cutter disc is provided with a main cutter disc protective cover, and both ends of the main cutter disc protective cover are provided with chip guide plates extending to the top of the milling chip collection grooves.

[0010] Furthermore, the chamfering and milling module comprises an inclined mounting plate, a sliding seat is arranged on the mounting plate, a driving motor 1 is arranged on the sliding seat, and a chamfering and milling cutter disc is arranged at the output end of the driving motor 1.

[0011] Furthermore, the number of the chamfering milling modules is two and they are symmetrically distributed with the center line of the gantry as the axis.

[0023] Example 1

[0024] like Figure 1 to Figure 4 As shown, a titanium ingot eight-sided milling machine includes a conveying device and a milling assembly arranged above the conveying device. The conveying device includes a guide rail 1, on which a workbench 2 for driving the titanium ingot to move is slidably provided. The workbench 2 is driven by a motor to move on the guide rail 1;

[0025] The milling assembly includes a gantry 3, a main milling module installed in the middle of the gantry 3, a chamfering milling module installed on one side of the gantry 3, and a side milling module installed on the other side of the gantry 3. The chamfering milling module is located in front of the main milling module. This distribution form can chamfer the burrs generated by chamfering milling during the main milling operation, thereby improving the processing quality of the product.

[0026] The main milling module includes a main milling cutter disc 4 located directly below the gantry 3 and a driving device located above the gantry 3. The driving device and the main milling cutter disc 4 are connected by a transmission shaft 5. The driving device adopts a motor reducer, and the motor reducer is connected to the transmission shaft 5 through a sliding gear coupling. The inner teeth are installed on the motor, and the motor and the inner teeth are fixedly installed. The outer gear sleeve of the sliding gear coupling is raised and lowered, and the inner teeth are stationary, so that the height of the milling head can be adjusted.

[0027] A rough milling cutter seat 6 and a fine milling cutter seat 7 are provided on the main milling cutter disc 4. The number of the rough milling cutter seats 6 and the fine milling cutter seats 7 are both multiple and staggered along the circumferential direction of the main milling cutter disc 4. The number of the rough milling cutter seats 6 is greater than the number of the fine milling cutter seats 7. The staggered distribution of the rough milling cutter seats 6 and the fine milling cutter seats 7 are used to jointly complete the milling operation on the surface of the titanium ingot.

[0028] Milling chip collection grooves 8 are arranged on both sides of the main milling cutter disc 4 and are located on the outside of the workbench 2. A main cutter disc protective cover 9 is installed on the outside of the main milling cutter disc 4. The design of the main cutter disc protective cover 9 can protect the main milling cutter disc 4 and prevent milling chips from entering the cutter disc. Chip guide plates 10 extending to the top of the milling chip collection groove 8 are arranged at both ends of the main cutter disc protective cover 9. The chip guide plates 10 can prevent milling chips from splashing upwards and are more conducive to the collection of milling chips. A bearing 11 connected to the main shaft is arranged on the upper part of the main cutter disc protective cover 9. The stable rotational motion of the main shaft can be guaranteed by the connection through the bearing 11.

[0029] The chamfering milling module includes an inclined mounting plate 12 with an inclination angle of 20-30 degrees. The inclination angle is adjusted according to the milling requirements. A sliding seat 13 is provided on the mounting plate 12. The sliding seat 13 is driven by a ball screw. A sliding groove is provided on the mounting plate 12 to provide guidance for the sliding seat 13. A driving motor 14 is provided on the sliding seat 13.

[0030] The number of chamfer milling modules is two and they are symmetrically distributed with the center line of the gantry 3 as the axis.

[0031] An angular milling protective cover 16 is provided on the outside of the chamfering milling cutter disc 15. An avoidance groove 17 for the passage of the titanium ingot is opened in the middle part of the angular milling protective cover 16 along the axial direction. The avoidance groove 17 is L-shaped, and a passing gap is reserved between the two side edges of the avoidance groove 17 and the upper surface and side surface of the titanium ingot, which will not affect the passage of the titanium ingot while protecting the chamfering milling cutter disc.

[0032] The side milling module includes a horizontally placed drive motor 18, and a side milling cutter disc 19 is provided at the output end of the drive motor 18. The side milling cutter disc 19 is located behind the gantry 3 and performs high-quality milling processing on the side wall after the chamfering cutter disc mills the side wall.

[0033] When in use, first install the main milling cutter disc, the diameter of which is 1850mm. The large-diameter milling cutter disc can cover the upper milling surface of the titanium ingot in one milling operation. Compared with the general milling cutter disc, it does not need to perform multiple reciprocating milling, which reduces the occurrence of the cutter seam. Then install the chamfering milling cutter disc 15 on the front side of the gantry 3, and the side milling cutter disc on the rear side of the gantry 3. The diameters of the chamfering milling cutter disc 15 and the side milling cutter disc are both 300mm. Place the titanium ingot to be milled on the workbench 2. As the workbench 2 moves Moving forward, the chamfering milling cutter disc 15 first mills the edges and corners on the upper parts of both sides of the titanium ingot. As the workbench 2 moves forward, the main milling cutter disc 4 mills the upper surface of the pad, and finally the side milling cutter disc 19 mills the side wall of one side of the titanium ingot. After completing one milling operation, the titanium ingot is turned over using a conventional turning machine. After turning over, the other four surfaces are milled. Through this equipment, only two milling operations are required to achieve milling operations on the eight surfaces of the titanium ingot, thereby improving the surface quality of the product and greatly improving the processing efficiency of the workpiece.
