Description

Technical Field

[0001] This utility model mainly relates to the technical field of horizontal heavy-duty milling machines, specifically a four-station horizontal heavy-duty milling machine. Background Technology

[0002] Horizontal heavy-duty milling machines are a common type of metal cutting machine tool, mainly used for milling workpieces. They are called "horizontal" because their spindle is placed horizontally and parallel to the horizontal plane of the machine bed. "Heavy-duty" refers to the fact that this type of milling machine has a large cutting force and rigidity, enabling it to perform heavy cutting. It is suitable for machining metal workpieces with high hardness or large volume. Horizontal heavy-duty milling machines are widely used in mechanical manufacturing, mold manufacturing, aerospace, shipbuilding and other fields. Due to their high efficiency and reliability, they are important equipment in many heavy industries and large processing workshops.

[0003] Currently, the traditional single-station milling method is mostly used in the processing and production of automotive parts. Only one workpiece can be processed at a time, and the entire production cycle is relatively long. Especially in the processing of complex workpieces, the processing time of each workpiece will accumulate, and operators need to frequently load and unload materials and adjust the position of workpieces. This increases the labor intensity and time cost, so it cannot meet the mass production of automotive parts and cannot keep up with the current market demand. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. Specifically, this utility model provides a four-station horizontal heavy-duty milling machine to solve the problem mentioned in the background that the current processing and production of automotive parts mostly adopts the traditional single-station processing method, which can only process one workpiece at a time, resulting in high labor costs, low efficiency, and inability to meet the current technical problem of mass production.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A four-station horizontal heavy-duty milling machine includes a bed, on which a turntable and slag removal channels on both sides are provided. A milling mechanism is provided near each of the slag removal channels. The two milling mechanisms are used for roughing and finishing automotive parts, respectively. A multi-station rotary table is provided on the turntable. The four positive directions of the multi-station rotary table are respectively provided with a detachable first fixture for loading and unloading, a second fixture for roughing, a third fixture for adjusting position, and a fourth fixture for finishing.

[0007] Furthermore, each of the slag discharge channels is equipped with a first motor at one end, and the output end of the first motor is equipped with a spiral push shaft that passes through the corresponding slag discharge channel.

[0008] Furthermore, each of the slag discharge channels is provided with two guide plates on one side of its upper edge.

[0009] Furthermore, the milling mechanism includes a base, on which a second motor and a spindle box are mounted, and the output end of the second motor is connected to the input end of the spindle box via a gear.

[0010] Furthermore, the output end of the spindle box is provided with a cutter shaft, and the cutter shaft is provided with multiple disc milling cutters.

[0011] Furthermore, the base is also provided with a support block, and a bearing seat is slidably connected to the support block. The bearing seat and the corresponding cutter shaft are rotatably connected.

[0012] Furthermore, the lower side of the base is provided with multiple sliders and a connecting block. The sliders are slidably connected to a slide rail, the connecting block is located at the output end of the servo motor, and both the servo motor and the slide rail are mounted on the bed.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention, through its bed, turntable, base, second motor, spindle box, cutter shaft, disc milling cutter, support block, and bearing seat, provides a four-station processing mode for machining automotive parts. It simultaneously processes four aspects: placement, roughing, part adjustment, and finishing, significantly improving production efficiency.

[0023] Please refer to the appendix carefully. Figure 1-3 A four-station horizontal heavy-duty milling machine includes a bed 1, on which a turntable 11 and slag discharge channels 12 on both sides are provided. A milling mechanism 3 is provided on one side of each slag discharge channel 12. The two milling mechanisms 3 are used for roughing and finishing of automotive parts, respectively. A multi-station rotary table 2 is provided on the turntable 11. The four positive directions of the multi-station rotary table 2 are respectively provided with a detachable first tooling 21 for loading and unloading, a second tooling 22 for roughing, a third tooling 23 for adjusting position, and a fourth tooling 24 for finishing.

[0024] The above structure enables a four-station machining mode in the processing of automotive parts, allowing simultaneous processing of four aspects: placement, roughing, part adjustment, and finishing. This significantly improves production efficiency. The separate arrangement of roughing and finishing shortens auxiliary processing time, reduces machine tool load, and increases machine tool life. For wear-prone tools, tool replacement is convenient and does not affect the normal use of other stations. The machine tool has good overall rigidity, and the processed products can be clamped in one go, ensuring high-efficiency and high-stability production requirements.

[0025] The specific operation is as follows: During the processing of automotive parts, the automotive parts to be processed are placed on the first workstation. The parts are then processed sequentially through roughing, adjustment, and finishing stations. The clamping of the parts relies on product contour positioning. Then, the servo motor 17 is started, pushing the milling mechanism 3 towards the second tooling 22 and the fourth tooling 24. Subsequently, the second motor 32 is started, and the spindle box 33 drives the cutter shaft 34 to rotate. As a result, the disc milling cutter 35 on the cutter shaft 34 rotates to perform processing, performing roughing and finishing on the parts on the second tooling 22 and the fourth tooling 24 respectively. At the same time, the first motor 13 drives the spiral push shaft 14 to rotate, guiding the metal chips scattered in the slag discharge channel 12 to one place and discharging them.

[0026] Please refer to the appendix carefully. Figure 2Each of the slag discharge channels 12 is equipped with a first motor 13 at one end. A spiral push shaft 14 is located at the output end of the first motor 13, passing through the corresponding slag discharge channel 12. Through the cooperation of the first motor 13, the spiral push shaft 14, and the slag discharge channel 12, the metal chips produced by milling are discharged from the machine bed 1. Two guide plates 15 are located on one side of the upper edge of each slag discharge channel 12, guiding the splashed metal chips into the slag discharge channel 12. The milling mechanism 3 includes a base 31, on which a second motor 32 and a spindle box 33 are mounted. The output end of the second motor 32 is connected to the input end of the spindle box 33 via gears. A cutter shaft 34 is located at the output end of the spindle box 33, and multiple disc milling cutters 35 are mounted on the cutter shaft 34. The second motor 32, the spindle box 33, and the cutter shaft 34 drive the disc milling cutters 35. For machining parts, the base 31 is also equipped with a support block 36, and a bearing seat 37 is slidably connected to the support block 36. The bearing seat 37 and the corresponding tool shaft 34 are rotatably connected. Through the support block 36 and the bearing seat 37, the tool positioning on the tool shaft 34 is achieved by a pull and a support method. The connection with the spindle end of the spindle box 33 is tightened, and the tail end is supported by the bearing seat 37. This ensures the consistency with the spindle accuracy and also meets the requirements of quick tool replacement. The bearing seat 37 is made of cast iron, which ensures that the tool shaft 34 has stronger rigid support. The lower side of the base 31 is equipped with multiple sliders 38 and a connecting block 39. The sliders 38 are slidably connected to the slide rail 16, and the connecting block 39 is located at the output end of the servo motor 17. Both the servo motor 17 and the slide rail 16 are located on the bed 1. The servo motor 17 provides driving force for the milling mechanism 3 to move to one side of the multi-station rotary table 2.
