Description

Technical Field

[0001] This application relates to the field of machining technology, and in particular to a worm gear type tilting frame. Background Technology

[0002] In the field of machinery manufacturing and processing, the handling of parts is a crucial link, and its efficiency and quality directly affect the entire production process. With continuous technological advancements and rapid industrial development, the requirements for parts processing, assembly, and testing are increasingly stringent. Especially in the handling of large mechanical parts, the multi-faceted processing needs have driven the continuous development of turnover frame equipment. For example, in industries such as automobile manufacturing and aerospace, parts vary in shape and size, requiring turnover frames to adapt to different specifications. Simultaneously, as the automation level of production lines continues to increase, higher demands are placed on the ease of operation and stability of turnover frames. Existing equipment for parts turnover includes various types, such as dedicated turnover machines, hydraulic turnover tables, robotic gripper turnover devices, and chain-type turnover mechanisms. However, existing turnover equipment can only fix workpieces of one model and size, resulting in poor versatility and failing to meet the processing needs of parts of different models and specifications. Utility Model Content

[0003] To improve the versatility of the equipment, this utility model provides a worm gear type tilting frame.

[0004] The worm gear type tilting frame provided by this utility model adopts the following technical solution:

[0005] A worm gear-type tilting frame includes a support frame, a drive device, and a fixing device. The drive device is connected to the support frame. The fixing device includes a fixed shaft, a first fixed plate, a first bolt, a second fixed plate, and a second bolt. The fixed shaft is rotatably connected to the support frame and is detachably connected to the support frame via a support structure. The support structure is connected to both the fixed shaft and the support frame. One end of the fixed shaft is connected to the drive device for driving the fixed shaft to rotate. The first fixed plate and the second fixed plate are detachably connected to the fixed shaft via clamping devices. The first fixed plate and the second fixed plate are spaced apart. The first bolt is connected to the first fixed plate, and multiple first bolts are provided and distributed circumferentially along the first fixed plate. The second bolt is connected to the second fixed plate, and multiple second bolts are provided and distributed circumferentially along the second fixed plate.

[0006] By adopting the above technical solution, when using the worm gear tilting frame, the first and second fixed plates are used to fix the workpiece. The drive device is connected to the support frame and can drive the fixed shaft to rotate, thereby causing the workpiece to tilt. This allows for multi-angle processing of parts, meeting the requirements for multi-angle processing of large mechanical parts. Since the fixed shaft and the support frame are detachably connected via a support structure, when it is necessary to fix the workpiece, the fixed shaft is first removed from the support frame, and then the first and second fixed plates are removed from the fixed shaft using a clamping device. One end of the first fixed plate is fixed to the workpiece with a first bolt, and the other end of the second fixed plate is fixed to the workpiece with a second bolt of the same specification. Then, the first fixed plate, the workpiece, and the second fixed plate are all fitted onto the fixed shaft, and finally, the first and second fixed plates are fixed to the fixed shaft using the clamping device. The clamping device allows for easy installation and removal of the first and second fixed plates and can firmly fix the items to be tilted, enabling the worm gear tilting frame to stably and reliably achieve the tilting operation during operation. Furthermore, different sizes of the first and second fixed plates can accommodate workpieces of different specifications, improving the equipment's versatility.

[0007] Preferably, the clamping device includes a clamping sleeve and a clamping bolt. The clamping sleeve is sleeved on the fixed shaft. The first fixed plate and the second fixed plate are fixedly connected to their respective clamping sleeves. The clamping sleeve has a first dividing hole and a second dividing hole. The first dividing hole is opened along the circumference of the clamping sleeve, and the second dividing hole is opened along the axial direction of the clamping sleeve. The first dividing hole and the second dividing hole communicate with each other. The first dividing hole and the second dividing hole enable the clamping sleeve to form a first clamping part and a second clamping part. The clamping bolt passes through the first clamping part and the second clamping part to fix the first clamping part and the second clamping part.

[0008] By adopting the above technical solution, a clamping device consisting of a clamping sleeve and a clamping bolt is provided between the first fixed plate, the second fixed plate and the fixed shaft. The clamping sleeve is connected to the fixed shaft. The clamping sleeve forms a first clamping part and a second clamping part by using circumferential and axial dividing holes and is fixed with clamping bolts. This can enhance the stability and reliability of the connection between the fixed plate and the fixed shaft and facilitate the installation and disassembly of the fixed plate.

[0009] Preferably, the driving device includes a driving component, a worm, a worm wheel, and an output rod. The driving component is connected to one end of the worm. The worm passes through the support frame and is rotatably connected to the support frame. The worm wheel meshes with the worm. The output rod is rotatably connected to the support frame. The worm wheel is fixedly connected to the output rod. The output rod is connected to the fixed shaft.

[0010] By adopting the above technical solution, the rotation of the driving component drives the worm to rotate, the worm drives the worm wheel meshing with it to rotate, the worm wheel drives the output rod to rotate, and the output rod drives the fixed shaft to rotate. This realizes the manual driving of the fixed shaft to rotate, which allows for flexible control of the fixed shaft's rotation. Moreover, the worm wheel and worm gear structure can achieve a large transmission ratio and has good stability and self-locking properties. At the same time, the connection between the output rod and the fixed shaft can transmit the power of the driving device to the fixed shaft, enabling the fixed device to rotate with the fixed shaft.

[0011] Preferably, a coupling is provided between the output rod and the fixed shaft, the coupling being fixedly connected to the output rod and detachably connected to the fixed shaft.

[0012] By adopting the above technical solution, a coupling is set to connect the output rod to the fixed shaft, ensuring that the drive device can drive the fixed shaft to rotate. The coupling and the fixed shaft are detachably connected, which facilitates the installation, disassembly and maintenance of the fixed shaft.

[0013] Preferably, the coupling has a first hole and a second hole at one end near the fixed shaft. The first hole is opened along the circumference of the coupling, and the second hole is opened along the axial direction of the coupling. The first hole and the second hole communicate with each other, forming a first fixed part and a second fixed part of the coupling. The coupling is connected with a connecting bolt, which passes through the first fixed part and the second fixed part and is threadedly connected to both the first fixed part and the second fixed part, thereby fixing the first fixed part and the second fixed part.

[0014] By adopting the above technical solution, this structure facilitates the detachable connection between the coupling and the fixed shaft, allows for flexible adjustment and replacement of components, and the setting of the first and second holes enhances the adjustability and adaptability of the coupling structure, which helps to improve the convenience of installation and the stability of the connection.

[0015] Preferably, the support structure includes a base block, a top block, and fixing bolts. The base block is fixedly connected to the support frame, and the top block is fixed to the base block by the fixing bolts. A placement space is formed between the base block and the top block. A bearing is provided in the placement space, and the fixing shaft passes through the bearing. The inner sidewall of the bearing is connected to the fixing shaft, and the outer sidewall is connected to the support structure.

[0016] By adopting the above technical solution, the support structure adopts a method of fixed connection between the bottom block and the support frame, and fixed connection between the top block and the bottom block by fixing bolts, which facilitates disassembly and installation; the placement space between the bottom block and the top block is equipped with bearings, which allows the fixed shaft to rotate flexibly, reduces friction during rotation, and the fixed shaft is detachably connected to the support frame, which facilitates maintenance and replacement of the fixed shaft.

[0017] Preferably, the bottom of the support frame is connected to a plurality of rollers, which are evenly distributed at the bottom of the support frame.

[0018] By adopting the above technical solution, multiple rollers are evenly distributed and connected to the bottom of the support frame, which makes the worm gear tilting frame easy to move and improves its flexibility and convenience of use.

[0019] In summary, this utility model has the following beneficial effects:

[0020] When using a worm gear-type tilting frame, the workpiece is fixed using a first and second fixed plate. The drive device is connected to the support frame and drives the fixed shaft to rotate, thereby tilting the workpiece. This allows for multi-angle processing of parts, meeting the requirements for multi-angle processing of large mechanical parts. Since the fixed shaft and support frame are detachably connected via a support structure, when fixing the workpiece, the fixed shaft is first removed from the support frame. Then, the first and second fixed plates are removed from the fixed shaft using a clamping device. One end of the first fixed plate is fixed to the workpiece with a first bolt, and the other end of the second fixed plate is fixed to the workpiece with a second bolt of the same specification. The first fixed plate, workpiece, and second fixed plate are then fitted onto the fixed shaft, and finally, the first and second fixed plates are fixed to the fixed shaft using the clamping device. The clamping device allows for easy installation and removal of the first and second fixed plates and securely fixes the items to be tilted, ensuring stable and reliable tilting operation of the worm gear-type tilting frame during operation. Furthermore, different sizes of the first and second fixed plates can accommodate workpieces of different specifications, improving the equipment's versatility. Attached Figure Description

[0030] A worm gear type tilting frame, reference Figure 1 and Figure 2The system includes a support frame 1, a drive unit 3, and a fixing device 4. The drive unit 3 is connected to the support frame 1. The fixing device 4 includes a fixing shaft 41, a first fixing plate 42, a first bolt 43, a second fixing plate 44, and a second bolt 45. The fixing shaft 41 is detachably connected to the support frame 1 via a support structure 7, and is also connected to the drive unit 3. Both the first fixing plate 42 and the second fixing plate 44 are detachably connected to the fixing shaft 41 via a clamping device 9. The first bolt 43 passes through the first fixing plate 42 and is threadedly connected to a first nut. Multiple first bolts 43 are provided and distributed circumferentially along the first fixing plate 42. The second bolt 45 passes through the second fixing plate 44 and is threadedly connected to a second nut. Multiple second bolts 45 are provided and distributed circumferentially along the second fixing plate 44.

[0031] Both the first fixed plate 42 and the second fixed plate 44 are available in various sizes to accommodate workpieces of different specifications. Driven by the drive device 3, they rotate, enabling the flipping operation of the parts.

[0032] Reference Figure 1 The bottom of the support frame 1 is connected to multiple rollers 2, which are evenly distributed at the bottom of the support frame 1. The rollers 2 can be casters, directional wheels, etc., which improves the flexibility of the equipment.

[0033] Reference Figure 1 The support frame 1 is provided with a first column 11, a second column 12, and a third column 13. The drive device 3 is connected to the first column 11. One end of the fixed shaft 41 is connected to the second column 12, and the other end is connected to the third column 13.

[0034] Reference Figure 1 and Figure 2 The drive device 3 includes a drive component, a worm gear 32, a worm wheel 33, and an output rod 34. The worm gear 32 is horizontally positioned, passes through the first column 11, and is rotatably connected to the first support column. The drive component is fixedly connected to one end of the worm gear 32. The drive component can be a handwheel 31, a motor, etc. In this embodiment, the drive component is a handwheel 31. The handwheel 31 is a component that is easy for the operator to operate manually. It is usually round, and when the operator turns the handwheel 31, it can drive the worm gear 32 to rotate.

[0035] Reference Figure 1 and Figure 2 The worm gear 33 is located in the hollow part of the first column 11 and meshes with the worm 32. The output rod 34 passes through the worm gear 33 and is fixedly connected to it. The output rod 34 also passes through the first column 11 and is rotatably connected to it. One end of the output rod 34 is fixedly connected to a coupling 5.

[0036] When the worm 32 rotates, it drives the worm wheel 33 to rotate through the transmission principle of the worm 32. The worm wheel 33 and worm 32 transmission has a self-locking function, which means that when the operator stops turning the handwheel 31, the fixed shaft 41 can remain in its current position and will not rotate on its own due to the gravity of the parts or other external forces, ensuring the safety and stability of the flipping operation. For example, in the flipping process of some large mechanical parts, when the parts are flipped to a specific angle, no additional locking device is needed. The self-locking function of the worm wheel 33 and worm 32 can keep the parts stably at that angle, facilitating subsequent processing, assembly, or inspection operations.

[0037] Reference Figure 3 The coupling 5 has a first hole 51 and a second hole 52 at the end away from the output rod 34. The first hole 51 is opened circumferentially along the coupling 5, and the second hole 52 is opened axially along the coupling 5. One end of the second hole 52 communicates with the first hole 51, and the other end passes through the end face of the coupling 5 away from the output rod 34. The first hole 51 and the second hole 52 make the coupling 5 form a first fixed part 53 and a second fixed part 54.

[0038] Reference Figure 3 The coupling 5 is connected with a connecting bolt 6, which passes through the first fixing part 53 and the second fixing part 54 and is threadedly connected to both the first fixing part 53 and the second fixing part 54, in order to fix the first fixing part 53 and the second fixing part 54.

[0039] When installing the fixed shaft 41, first insert the fixed shaft 41 into the coupling 5, and then tighten the connecting bolts 6 to tightly clamp the fixed shaft 41 with the first fixing part 53 and the second fixing part 54, achieving a reliable connection. This connection method is not only convenient to install, but also ensures torque transmission between the output rod 34 and the fixed shaft 41, ensuring that the drive device 3 can effectively drive the fixed shaft 41 to rotate. When it is necessary to replace the fixed shaft 41 with a different specification to adapt to different component flipping requirements, simply loosen the connecting bolts 6 to easily disassemble and install the fixed shaft 41, improving the maintainability and versatility of the equipment.

[0040] Reference Figure 2 Both ends of the fixed shaft 41 are connected to support structures 7. The support structure 7 includes a base block 71, a top block 72, and fixing bolts 74. The base block 71 is fixedly connected to the support frame 1, and the top block 72 is fixed to the base block 71 by the fixing bolts 74. A placement space 73 is formed between the base block 71 and the top block 72. A bearing 8 is provided in the placement space 73, and the fixed shaft 41 passes through the bearing 8. The inner side wall of the bearing 8 abuts against the fixed shaft 41, and the outer side wall is grounded to the support structure 7.

[0041] The combination of the bottom block 71, the top block 72, and the fixing bolts 74 allows the bearing 8 and the fixed shaft 41 to be fixed within the support structure 7. Simultaneously, by simply loosening the fixing bolts 74 and removing the top block 72, the bearing 8 can be easily removed from the placement space 73, and the bearing 8 and the fixed shaft 41 are also easily disassembled, greatly improving the equipment's maintenance efficiency.

[0042] Reference Figure 4 The clamping device 9 includes a clamping sleeve 91 and a clamping bolt 92. The clamping sleeve 91 is fitted onto the fixed shaft 41 and is keyed to the fixed shaft 41. The fixed shaft 41 is available in various sizes so that the position of the key that mates with the clamping sleeve 91 can be adapted to the size of the workpiece. The first fixed plate 42 and the second fixed plate 44 are disc-shaped structures, and the first fixed plate 42 and the second fixed plate 44 are spaced apart. The first fixed plate 42 and the second fixed plate 44 are fixedly connected to their respective clamping sleeves 91 by bolts.

[0043] Reference Figure 4 The clamping sleeve 91 has a first dividing hole 911 and a second dividing hole 912. The first dividing hole 911 is opened along the circumference of the clamping sleeve 91, and the second dividing hole 912 is opened along the axial direction of the clamping sleeve 91. The first dividing hole 911 and the second dividing hole 912 communicate with each other, forming a first clamping part 913 and a second clamping part 914 on the clamping sleeve 91. The clamping bolt 92 passes through the first clamping part 913 and the second clamping part 914 to fix the first clamping part 913 and the second clamping part 914.

[0044] When installing the first fixed plate 42 and the second fixed plate 44, first, the clamping sleeve 91 is placed on the fixed shaft 41. Then, the first fixed plate 42 or the second fixed plate 44 is placed in a suitable position. Finally, by tightening the clamping bolts 92, the first clamping part 913 and the second clamping part 914 are tightly clamped onto the fixed shaft 41, thereby firmly fixing the first fixed plate 42 or the second fixed plate 44 onto the fixed shaft 41. This clamping device 9 design makes the installation and removal of the first fixed plate 42 and the second fixed plate 44 very convenient.

[0045] The operating principle of this application is as follows: In use, first adjust the fixing bolt 74 to remove the fixing shaft 41 from the placement space 73. Adjust the clamping bolt 92 to allow the clamping sleeve 91 to move on the fixing shaft 41, and then detach the first fixing plate 42 and the second fixing plate 44 from the fixing shaft 41. The first fixing plate 42 is fixed to one end of the workpiece by the first bolt 43, and the second fixing plate 44 is fixed to the other end of the workpiece by the same specification second bolt 45. Then, the first fixing plate 42, the workpiece, and the second fixing plate 44 are all fitted onto the fixing shaft 41. The first fixing plate 42 and the second fixing plate 44 are then fixed to the fixing shaft 41 by the clamping device 9. The clamping device 9 is adjusted again to install the first fixing plate 42 and the second fixing plate 44, fixing them to the fixing shaft 41. Bearings 8 are fitted onto both ends of the fixing shaft 41 and placed in the placement space 73. One end of the fixing shaft 41 is fixed to the coupling 5, and then the top block 72, the bottom block 71, and the fixing bolt 74 cooperate to support the fixing shaft 41.

[0046] The operator rotates handwheel 31, which drives worm gear 32 to rotate. Worm gear 32 drives worm wheel 33 to rotate, which in turn drives output rod 34 to rotate. Output rod 34 drives fixed shaft 41 to rotate via coupling 5, thereby causing the workpiece to flip. This allows for multi-angle processing of parts, meeting the requirements for multi-angle processing of large mechanical parts. The fixing device 4 can be replaced with different specifications, facilitating the installation and fixing of workpieces of different sizes and improving the equipment's versatility.

[0047] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
