Description

Technical Field

[0001] This utility model relates to the field of milling technology, and in particular to a structure for a multi-angle swing table for milling. Background Technology

[0002] Milling is a common process in metal processing, which involves cutting a workpiece using a rotating cutting tool. Traditional milling machines can no longer achieve the required precision. Ordinary milling requires multiple disassembly and reassembly of the workpiece to mill different planes. For machining, each disassembly and reassembly reduces the precision and increases the error of the workpiece. It also increases the labor intensity and reduces the production speed. Therefore, it is necessary to design a multi-angle swing table structure for use in milling.

It comprises a fixed plate and a support plate mounted on the top surface of a base plate. The support plate is located on one side of the fixed plate, and a transmission box is mounted on one side surface of the support plate. A rotating rod is installed through the front of the transmission box, and a worm gear is mounted on the inner wall of the transmission box via bearings. One end of the worm gear is connected to the tail end of the rotating rod, and a crank handle is mounted on one end of the rotating rod. A rotating shaft is installed through one side surface of the support plate. This invention, by installing an adjusting plate, a rotating shaft, and a transmission box, allows for adjustment of the workpiece clamping angle during milling operations, satisfying multi-angle milling requirements and increasing the applicability and practicality of the clamping structure.

Second, the structure cannot adjust the height of the adjusting plate based on its position within the milling machine. In milling, adjusting the workpiece height is crucial for ensuring machining accuracy and avoiding collisions. Therefore, the aforementioned structure is neither practical nor convenient.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-5 As shown, a milling multi-angle swing table structure includes a base plate 1. Mounting holes are provided through the four corners of the upper end of the base plate 1. A cylindrical sleeve 5 is rotatably connected to the middle of the upper end of the base plate 1. A sliding column 6 is slidably connected to the inner wall of the cylindrical sleeve 5. A multi-position adjustment component 2 is fixedly connected to the bottom of the outer wall of the cylindrical sleeve 5 and the top of the outer wall of the sliding column 6. A mounting plate 7 is fixedly installed on the upper end of the sliding column 6. A protective frame 8 is fixedly installed on the upper edge of the mounting plate 7. A vertical adjustment component 3 is movably connected to the inner wall of the protective frame 8. A worktable 9 is fixedly connected to the left and right sides of the vertical adjustment component 3. A fixing component 4 is fixedly installed on the left and right sides of the upper end of the worktable 9.

[0028] The multi-position adjustment assembly 2 includes two hydraulic rods 21. The lower ends of the two hydraulic rods 21 are fixedly connected to the front and rear parts of the upper end of the base plate 1. The output ends of the two hydraulic rods 21 are fixedly connected to symmetrically arranged fixing plates 22. Adjusting rings 23 are fixedly connected to the opposite sides of the two fixing plates 22. An annular groove 24 is opened in the middle of the inner wall of the adjusting ring 23. An annular strip 25 matching the annular groove 24 is fixedly installed on the top of the outer wall of the sliding column 6. A horizontal adjustment mechanism is fixedly connected to the bottom of the outer wall of the cylindrical sleeve 5.

[0029] The vertical adjustment assembly 3 includes a rotating shaft 31 and a connecting shaft 32. The lower end of the rotating shaft 31 is rotatably connected to the upper middle part of the mounting plate 7. The left and right ends of the connecting shaft 32 are rotatably connected to the top of the inner wall of the protective frame 8. The left and right parts of the outer wall of the connecting shaft 32 pass through the left and right parts of the protective frame 8 and are fixedly sleeved with connecting plates 33. The upper ends of the two connecting plates 33 are fixedly connected to the lower left and right parts of the worktable 9. A drive mechanism is fixedly connected to the top of the outer wall of the rotating shaft 31 and the middle of the outer wall of the connecting shaft 32.

[0030] The horizontal angle of the worktable 9 and its height from the base plate 1 can be adjusted via the multi-position adjustment component 2. The worktable 9 primarily utilizes hydraulic lifting and gear transmission for rotation, enabling processing of workpieces in different directions while ensuring machining accuracy and preventing collisions through workpiece height adjustment. This enhances the overall structural flexibility. The vertical adjustment component 3 allows for rapid adjustment of the vertical angle of the worktable 9. The worm gear 37 and worm 35 transmission have self-locking properties, improving the stability of angle adjustment. The bevel gear linkage transmits the rotational force of the rotating shaft 31 to the connecting shaft 32, causing the connecting shaft 32 to drive the worktable 9 to rotate vertically via two connecting plates 33, resulting in high practicality.

[0031] The hydraulic drive provides a height adjustment stroke of ±200mm or more, and the gear transmission enables stepless horizontal rotation from 0 to 360°.

[0032] like Figure 4 and Figure 5 As shown, the horizontal adjustment mechanism includes gear 26 and gear 27. The inner wall of gear 26 is fixedly connected to the bottom of the outer wall of the cylindrical sleeve 5. Motor 28 is fixedly installed on the upper right side of the base plate 1. The output end of motor 28 is fixedly connected to the inner wall of gear 27. The outer surface of gear 26 meshes with the outer surface of gear 27.

[0033] The output of motor 28 can drive gear 27 to rotate. Gear 26 meshes with gear 27 to drive cylindrical sleeve 5 to rotate. The two sliding grooves 29 inside cylindrical sleeve 5 drive sliding column 6 to rotate through the two sliding strips 210 on the outer wall of sliding column 6. When sliding column 6 rotates, the annular strip 25 slides in the annular groove 24.

[0034] like Figure 4 As shown, the inner wall of the cylindrical sleeve 5 is provided with sliding grooves 29 on both the left and right sides, and the outer wall of the sliding column 6 is fixedly installed with two matching sliding strips 210 at the position below the adjusting ring 23.

[0035] The groove 29 guides the movement of the sliding column 6.

[0036] like Figure 5 As shown, the drive mechanism includes two mounting blocks 34. The lower ends of the two mounting blocks 34 are fixedly mounted to the upper right side of the mounting plate 7. The inner walls of the two mounting blocks 34 are rotatably connected to worm gears 35. A second motor 36 is fixedly mounted at the front position of the upper right side of the mounting plate 7. The output end of the second motor 36 is fixedly connected to the front end of the worm gear 35. A worm wheel 37 is fixedly sleeved on the bottom of the outer wall of the rotating shaft 31. The outer wall of the worm gear 35 meshes with the outer surface of the worm wheel 37.

[0037] The output end of motor 36 can drive worm 35 to rotate, and worm wheel 37 drives shaft 31 to rotate by meshing with worm 35.

[0038] like Figure 5 As shown, a bevel gear 38 is fixedly sleeved on the top of the outer wall of the rotating shaft 31, and a bevel gear 39 is fixedly sleeved on the middle of the outer wall of the connecting shaft 32. The outer surface of the bevel gear 38 meshes with the outer surface of the bevel gear 39.

[0039] When the shaft 31 rotates, the first bevel gear 38 meshes with the second bevel gear 39, transmitting the rotational force of the shaft 31 to the connecting shaft 32, so that the connecting shaft 32 can drive the worktable 9 to rotate a specified angle in the vertical direction through the two connecting plates 33.

[0040] like Figure 3 As shown, the fixing component 4 includes two vertical plates 41. The lower ends of the two vertical plates 41 are fixedly installed on the upper left and right sides of the worktable 9. The middle of the two vertical plates 41 on opposite sides is threaded with adjusting screws 42. The opposite ends of the two adjusting screws 42 are rotatably connected with positioning plates 43.

[0041] Rotating the two adjusting screws 42 can drive the two positioning plates 43 to clamp and fix the workpiece between them.

[0042] like Figure 3 As shown, guide posts 44 are slidably connected to the front and rear parts of the two vertical plates 41 on opposite sides, and the opposite ends of the four adjacent guide posts 44 are fixedly connected to the front and rear parts of the two positioning plates 43 on opposite sides.

[0043] The guide post 44 guides the movement of the positioning plate 43.

[0044] The working principle of this utility model is as follows: This multi-angle swing milling table 9 achieves multi-axis linkage machining through a three-in-one adjustment design (horizontal rotation, vertical swing, and height adjustment). In use, the workpiece is placed between two positioning plates 43, and rotating the two adjusting screws 42 causes the two positioning plates 43 to clamp and fix the workpiece between them. When the two hydraulic rods 21 are activated, their output ends can drive the slide column 6 to rise and fall through the annular groove 24 inside the adjusting ring 23 and the annular strip 25 on the surface of the slide column 6. When the motor 28 is activated, its output end can drive the gear 27 to rotate. The gear 26, through meshing with the gear 27, drives the cylindrical sleeve 5 to rotate. The two sliding grooves 29 inside the cylindrical sleeve 5 drive the slide column 6 to rotate through the two sliding strips 210 on the outer wall of the slide column 6. Furthermore, when the slide column 6 rotates, the annular strip 25 slides within the annular groove 24. The table 9 mainly utilizes hydraulic drive for lifting and gear transmission for rotation, which not only meets the machining needs of workpieces in different directions but also ensures machining accuracy and avoids collisions through workpiece height adjustment. This improves the overall flexibility of the structure. Specifically, the hydraulic lifting mechanism, linked to the milling machine connected to the base plate 1, enhances workpiece machining accuracy.

[0045] When motor 26 starts, its output can drive worm 35 to rotate, and worm wheel 37 drives shaft 31 to rotate by meshing with worm 35. When shaft 31 rotates, bevel gear 1 38 meshes with bevel gear 2 39, transmitting the rotational force of shaft 31 to connecting shaft 32, so that connecting shaft 32 can drive worktable 9 to rotate vertically by a specified angle through two connecting plates 33. Motor 1 28, motor 2 36 and hydraulic rod 21 are connected to the control system of the external structure through wires.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
