Description

Technical Field

[0001] This invention relates to the field of machining technology, specifically to a multi-angle adjustable bracket for milling. Background Technology

[0002] In modern machining, milling is a crucial machining method widely used in aerospace, automotive manufacturing, mold making, and many other industries. With the continuous development of the manufacturing industry, higher demands are being placed on the precision, efficiency, and ability to process complex parts in milling. However, traditional milling supports are mostly fixed in structure and have limited angle adjustment functions, often only allowing for simple horizontal or vertical fine adjustments, making it difficult to meet the machining needs of complex curved surfaces, multi-angle inclined surfaces, and other special workpieces. In actual machining, operators need to spend a significant amount of time and effort adjusting the angle and position of the workpiece, which not only reduces machining efficiency but also easily leads to decreased machining accuracy due to inaccurate angle adjustment, resulting in scrap and increased production costs. Furthermore, the operation and control methods of traditional supports are cumbersome, requiring operators to possess high levels of professional skills and experience, which hinders the popularization and promotion of this machining operation.

[0003] Several related solutions already exist in the prior art. For example, invention patent CN107745266B discloses a mechanical bending plate type inclined adjustment fixture and method. This fixture includes a fixture base, side plates, and a middle plate. A servo motor drives a worm gear mechanism, which in turn drives the gear shaft to mesh with the sector teeth on the back of the rotating table, thereby adjusting the workpiece clamping angle. This solution has the advantages of structural stability, good rigidity, reduced labor intensity, and improved work efficiency. Chinese invention patent CN109333112A discloses a special fixture and processing method for upper mold processing. Through the cooperation of the mold base, lower support, upper adjustment component, and angle adjustment mechanism, the mold base is driven to rotate with the lower support component as the fulcrum to adjust the angle of the upper mold cutting edge, placing it in a horizontal processing position. Wedge blocks are used for fine-tuning the height, thus adapting to milling of cutting edge surfaces with different angles. It features high positioning accuracy and strong support stability.

[0004] Nevertheless, developing a milling support that can achieve more flexible multi-angle operation, more convenient adjustment, and more efficient operation remains an urgent need to solve current milling problems and promote the development of the manufacturing industry. Summary of the Invention

[0005] The purpose of this invention is to provide a solution to the problem that traditional milling support angle adjustment functions are limited and cannot meet the processing needs of complex workpieces. Another purpose of this invention is to effectively improve processing efficiency, reduce the professional skills required of operators, and promote the popularization and promotion of milling operations.

[0006] The technical solution of the present invention: A multi-angle adjustment bracket for milling, comprising a support cavity with a rotating groove, a sliding groove at the side end of the support cavity, and further comprising... Rotation mechanism: a toothed groove on the circumferential side wall of the turntable, a slide plate slidably disposed in the groove, a transmission tooth fixed to the lower surface of the slide plate and meshing with the toothed groove, and an electric telescopic rod for driving the slide plate to slide. The clamping device includes a support rod hinged to the end face of the turntable and a hydraulic rod disposed between the support rod and the turntable. The end face of the support rod is connected to a clamping part, and the hydraulic rod drives the support rod and the clamping part to move up and down and change angle. The control mechanism, located in the lower part of the support cavity, is used to control the movement of the electric telescopic rod and the hydraulic rod respectively.

[0007] Furthermore, a support plate is fixedly connected to the upper surface of the slide plate, and a vertical plate is fixedly connected to one side of the upper surface of the support cavity. An electric telescopic rod is fixedly connected between the vertical plate and the support plate. The electric telescopic rod extends and retracts to drive the support plate, and the support plate drives the slide plate to slide left and right to realize the rotation of the turntable and move within the plane of rotation.

[0008] Furthermore, the clamping device also includes a groove block, inside which a support rod is rotatably connected, and the other end of the support rod is fixedly connected to a clamping part.

[0009] Furthermore, the clamping part includes a supporting vertical plate, with an upper clamping plate and a lower clamping plate respectively connected to the upper and lower ends of the supporting vertical plate. The lower clamping plate can slide up and down along the supporting vertical plate, and one end of the lower clamping plate is fixedly connected to the inner end face of the upper clamping plate and passes vertically through the lower clamping plate and is rotatably connected to it.

[0010] Furthermore, the control mechanism includes a control cavity connected to the lower surface of the support cavity, and the control cavity is provided with a rotating column, a pressure ring, a pressure strip, a push switch and a contact switch; After the pressure ring is pressed, the pressure bar contacts the pressure switch, which triggers the pressure switch. The pressure switch then transmits a signal to the corresponding control unit, thereby controlling the operation of the electric telescopic rod. Loosen the pressure ring and rotate the rotating column to make the pressure bar contact the contact switch, thereby controlling the operation of the hydraulic rod.

[0011] Furthermore, a rotating column is rotatably connected to the end face of the control cavity, a disc is slidably connected inside the rotating column, the disc is fixedly connected to a support column, a pressing ring is fixedly connected to the other end of the support column, and a return spring is fixedly connected between the disc and the inside of the control cavity.

[0012] Furthermore, the rotating column has symmetrical vertical grooves on its side wall, and a pressing strip is provided that passes horizontally through the two vertical grooves and is fixed to the end face of the disc. A contact switch and a pressing switch are fixedly provided on the side end of the rotating column and on the control cavity.

[0013] Furthermore, the contact switch is flat and vertically mounted on the upper end of the control cavity. Its vertical end face is offset from the pressure bar and is not on the same horizontal line. The outer wall of the contact switch is symmetrically fixed with protruding push switches, which can contact the push switches when the pressure bar slides down.

[0014] Furthermore, the outer wall of the support cavity is symmetrically fixedly connected with perforated mounting blocks.

[0015] The beneficial effects of this invention are: 1. This invention, through a transmission structure between an electric telescopic rod and a turntable, enables precise control of the workpiece's horizontal rotation angle. The electric telescopic rod drives a sliding plate to slide within a groove. The transmission teeth on the lower surface of the sliding plate mesh with the tooth grooves on the outer wall of the turntable, causing the turntable to rotate and thus adjusting the workpiece's horizontal angle. In the vertical direction, a hydraulic rod, through its rotational connection with a support rod, can precisely adjust the workpiece's height and tilt angle. This multi-angle adjustment function allows the support to adapt to various complex milling tasks. Whether it's plane milling, inclined plane milling, or curved surface milling, it ensures the workpiece is at the optimal machining angle, greatly improving machining accuracy and quality, reducing scrap rates caused by improper angle adjustment, and providing a reliable solution for milling complex parts.

[0016] 2. This invention features a unique control cavity and related structure, providing operators with a convenient and efficient control method. During processing, simply pressing and rotating the pressure ring triggers the push-button switch and contact switch via the transmission of the disc, rotating column, and pressing strip, thus controlling the electric telescopic rod and hydraulic rod. This push-button operation is simple and intuitive, requiring no complex operating procedures or professional skills training, allowing operators to quickly learn how to use it. Furthermore, by cooperating with different contact switches, precise control of different components can be achieved, enabling rapid response when fine adjustments to the workpiece angle and position are needed, greatly improving processing efficiency.

[0017] 3. The clamping device of the present invention uses a threaded fastening method to clamp the workpiece, which is convenient to operate and provides a firm clamping, ensuring the stability of the workpiece during the processing and further improving the convenience and reliability of the overall operation.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. However, it should not be construed that the scope of the subject matter of the present invention is limited to the following embodiments. All modifications, substitutions and alterations made based on ordinary technical knowledge and common practices in the art without departing from the above-described technical concept of the present invention are included within the scope of the present invention.

[0021] like Figure 1 - Figure 5 As shown, a multi-angle adjustable bracket for milling is provided, including a support cavity 1. A rotating groove 2 is formed on the front surface of the support cavity 1. A turntable 3 is rotatably connected to the inner rear surface of the rotating groove 2. A clamping device 4 is fixedly connected to the front surface of the turntable 3. A toothed groove 5 is fixedly connected to the outer side wall of the turntable 3. A through-type sliding groove 6 is formed on the right side of the support cavity 1. A sliding plate 7 is slidably connected inside the sliding groove 6. A transmission tooth 8 is fixedly connected to the lower surface of the sliding plate 7. The transmission tooth 8 meshes with the toothed groove 5. A support plate 9 is fixedly connected to the right side of the upper surface of the sliding plate 7. A vertical plate 10 is fixedly connected to the left side of the upper surface of the support cavity 1. An electric telescopic rod 11 is fixedly connected between the vertical plate 10 and the support plate 9. A hydraulic rod 18 is fixedly connected to the front surface of the turntable 3. The hydraulic rod 18 and the support rod 13 are rotatably connected through a rotating connector.

[0022] The workpiece to be processed is placed on the clamping device 4, which securely clamps the workpiece to ensure it will not shift during subsequent processing. The electric telescopic rod 11 is then activated, causing the support plate 9 to slide within the slide groove 6 through its telescopic movement. Since the support plate 9 is fixedly connected to the slide plate 7, the slide plate 7 also slides within the slide groove 6. The transmission teeth 8 on the lower surface of the slide plate 7 mesh with the toothed grooves 5 on the outer wall of the turntable 3. The sliding of the slide plate 7 causes the transmission teeth 8 to rotate, which in turn drives the turntable 3 to rotate within the rotating groove 2 via the toothed grooves 5. By controlling the telescopic length and direction of the electric telescopic rod 11, the rotation angle of the turntable 3 can be precisely controlled, allowing for adjustment of the horizontal angle of the workpiece to meet the requirements of different milling processes.

[0023] When it is necessary to adjust the height and tilt angle of the workpiece, activate the hydraulic rod 18. Through its own telescopic movement, the hydraulic rod 18, via a rotating connector with the support rod 13, drives the components connected to it to adjust horizontally. By precisely controlling the telescopic amount and speed of the hydraulic rod 18, accurate horizontal adjustment can be achieved to meet various complex milling requirements. During milling, if the angle or position of the workpiece needs fine-tuning, the electric telescopic rod 11 and the hydraulic rod 18 can be activated again to make minor adjustments to the angle of the turntable 3, the height of the workpiece, and the tilt angle, ensuring machining accuracy. After milling, first turn off the electric telescopic rod 11 and the hydraulic rod 18 to stop their operation. Then, release the clamping device 4, remove the machined workpiece, and clean and maintain the multi-angle adjustment bracket to prepare for the next machining operation.

[0024] In this embodiment, the clamping device 4 includes a groove block 12, a support rod 13 is rotatably connected inside the groove block 12, a support vertical plate 14 is fixedly connected to the front surface of the support rod 13, an upper clamping plate 30 is fixedly connected to the front surface of the support vertical plate 14, a lower clamping plate 15 is slidably connected to the lower surface of the support vertical plate 14, a threaded groove 16 is provided on the outer side wall of the lower clamping plate 15, a bolt 17 is threadedly connected inside the threaded groove 16, and the top end of the bolt 17 is rotatably connected to the lower clamping plate 15.

[0025] The workpiece to be processed is placed in the groove formed by the lower clamping plate 15 and the upper clamping plate 30. The groove block 12 provides initial positioning for the workpiece, which is located in the space between the upper clamping plate 30 and the lower clamping plate 15. Depending on the thickness of the workpiece, the lower clamping plate 15, which is slidably connected to the lower surface of the supporting vertical plate 14, is manually slid up and down to adjust the distance between it and the upper clamping plate 30, ensuring the workpiece is approximately in the middle of the two plates and that the upper and lower clamping plates can effectively contact the workpiece surface. The bolt 17 is aligned with the threaded groove 16 on the outer wall of the lower clamping plate 15, and the bolt 17 is rotated clockwise. As the bolt 17 penetrates deeper into the threaded groove 16, it moves the lower clamping plate 15 upwards, gradually bringing it closer to the workpiece and into contact with the upper clamping plate 30. Apply initial clamping force to the workpiece together, and observe the workpiece position during the process to avoid displacement; use a wrench or other appropriate tools to further tighten bolt 17, and continue to push the lower clamping plate 15 upward to increase the clamping force of the upper clamping plate 30 and the lower clamping plate 15 on the workpiece until the workpiece is firmly clamped. When tightening, ensure that the clamping force is evenly distributed. You can check whether the clamping is firm by slightly shaking the workpiece. If there is any shaking, continue to tighten bolt 17; after the milling is completed, use a tool to rotate bolt 17 counterclockwise to remove it from the threaded groove 16. The lower clamping plate 15 slides downward under the action of gravity or with manual assistance. The clamping force of the upper clamping plate 30 and the lower clamping plate 15 on the workpiece disappears, and the finished workpiece can be taken out.

[0026] In this embodiment, a control cavity 19 is fixedly connected to the lower surface of the support cavity 1. A rotating column 20 is rotatably connected to the front surface of the control cavity 19. A disc 21 is slidably connected inside the rotating column 20. A support column 22 is fixedly connected to the front surface of the disc 21. A pressing ring 23 is fixedly connected to the front end of the support column 22. A return spring 24 is fixedly connected to the disc 21 and the inside of the control cavity 19. Vertical grooves 25 are symmetrically formed inside the control cavity 19. Pressing strips 26 are slidably connected inside each vertical groove 25. The pressing strips 26 pass through the vertical grooves 25 and are fixed to the end face of the disc 21. A contact switch 28 is fixedly connected to the front surface of the control cavity 19. A protruding pressing switch 27 is provided on the outer wall of the contact switch.

[0027] During the milling process, when certain functions of the bracket need to be controlled, the operator presses the pressing ring 23 by hand. The pressing ring 23 drives the support column 22 to move backward, which in turn pushes the disc 21 to slide inside the rotating column 20. The disc 21 slides backward, compressing the return spring 24. At the same time, since the disc 21 is connected to the pressing strip 26, the movement of the disc 21 will drive the pressing strip to slide within the vertical groove 25. When the pressing strip 26 slides to contact the pressing switch 27, the lower pressing switch 27 is triggered. The pressing switch 27 transmits a signal to the corresponding control unit, thereby controlling the operation of the electric telescopic rod 11. When the operator releases the pressing ring 23, under the elastic force of the return spring 24, the disc 21 returns to its original position. At this time, the rotating column 20 can be rotated to drive the pressing strip 26 to rotate and contact the contact switch 28, which can control the opening and closing of the hydraulic rod 18.

[0028] In this embodiment, the outer side wall of the support cavity 1 is symmetrically fixedly connected with a perforated mounting block 29.

[0029] In practical applications, the perforated mounting block 29 plays a crucial role in installation and fixation. When mounting a multi-angle adjustment bracket for milling onto a worktable or other equipment, first place the bracket in the predetermined installation position, aligning the holes on the perforated mounting block 29 with the corresponding mounting holes on the worktable or equipment. Then, insert suitable bolts, screws, or other connectors through the holes in the perforated mounting block 29 and the corresponding mounting holes, and tighten the connectors using tools such as wrenches and screwdrivers to securely fix the bracket in the target position through threaded fastening. For disassembly, reverse the process; unscrew the connectors to remove the bracket from its installation position, facilitating its movement, maintenance, or repositioning. The above provides a detailed description of a multi-angle adjustable bracket for milling operations provided by the present invention. Specific examples have been used to illustrate the structure and working principle of the invention. The descriptions of the embodiments above are merely for the purpose of helping to understand the method and core ideas of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
