Technical Field

[0001] The present application relates to the field of gear processing equipment, and in particular to a clamping device for gear processing. Background Art

[0002] Currently, during the gear processing, the clamping device plays a crucial role. It not only needs to stably fix the gear shaft to ensure the processing accuracy, but also needs to be flexible and adjustable to meet the processing requirements of different specifications and types of gears. With the development of industrial technology, the requirements for the clamping device are getting higher and higher, especially in terms of automation, intelligence and high efficiency.

[0003] A related clamping device for gear shaft processing includes: a support seat assembly, which includes a base and a rotating seat. The base includes a support portion and an installation portion. The support portion is used for fixedly connecting with the frame of the hobbing machine. One end of the rotating seat is hinged to one end of the installation portion, and the other end of the rotating seat is detachably connected to the other end of the installation portion through a locking member. A channel for clamping the shaft portion of the gear shaft is formed between the rotating seat and the installation portion; and a clamping assembly, with at least three clamping assemblies evenly distributed on the top of the closed ring formed by the rotating seat and the installation portion. The clamping assembly is used to clamp the shaft portion of the gear shaft in the channel; each clamping assembly includes: a mounting seat and a ejector rod. A fixing plate is fixed on the side wall of each mounting seat, and each fixing plate is fixed on the top of the closed ring through a locking bolt. A driving assembly is arranged on each mounting seat, and each ejector rod is arranged on the output end of the corresponding driving assembly. Each driving assembly is used to drive the ejector rod to approach or move away from the axis of the channel.

[0004] During the use of the clamping device in the related art, first, the support portion is fixed to the frame of the hobbing machine through bolts, then the locking member is disassembled to release the free ends of the rotating seat and the installation portion, rotate the rotating seat to open the channel, so that the shaft portion of the gear shaft can be inserted into the channel, then clamp one end of the gear shaft through the fixture arranged on the hobbing machine, and then rotate the rotating seat to close the channel, and the shaft portion of the gear shaft is clamped by the clamping assembly arranged on the rotating seat and the installation portion; therefore, the clamping device for gear shaft processing in the related art mainly relies on manual operation to rotate the rotating seat, resulting in a low degree of automation and reducing the overall work efficiency. Summary of the Invention

[0005] In order to improve the overall automation degree and the overall work efficiency of the gears, the present application provides a clamping device for gear processing.

[0006] A clamping device for gear processing provided by the present application adopts the following technical solutions: A clamping device for gear processing, comprising a base, a rotating seat, a rotating drive mechanism and a clamping mechanism. The rotating seat is rotatably connected to the base. The rotating drive mechanism is arranged on the base and is used to drive the rotating seat to rotate. The clamping mechanism is arranged on the rotating seat and is used to clamp the linkage gear.

[0007] By adopting the above technical solutions, a rotatable rotating seat is installed on the base, and a rotating drive mechanism is equipped to achieve the efficient rotation of the rotating seat. Then, a special clamping mechanism is arranged on the rotating seat to firmly clamp the linkage gear. This not only significantly improves the automation degree in the gear processing process, ensures the high precision and stability of gear processing, but also effectively enhances the overall working efficiency of gear processing through the optimized clamping mechanism.

[0008] Optionally, the clamping mechanism includes a mounting seat, a driving component and two clamping members. The mounting seat is arranged on the rotating seat, and the two clamping members are both slidably matched with the mounting seat. The driving component is arranged on the mounting seat and is used to drive the two clamping members to move towards each other or away from each other.

[0009] By adopting the above technical solutions, the two clamping members can move flexibly towards or away from each other under the precise control of the driving component, so as to realize the stable clamping of linkage gears of different specifications. This improvement not only further enhances the stability and precision during gear processing, but also greatly improves the adaptability and flexibility of the clamping device.

[0010] Optionally, the clamping member includes a rack, a connecting portion and a clamping portion. One end of the connecting portion is fixed to the rack, and the other end of the connecting portion is fixed to the clamping portion. Two sliding grooves are formed on the mounting seat, and the sliding grooves correspond to the racks one by one. The racks are slidably matched with the sliding grooves. The driving component is arranged on the mounting seat and is used to drive the two racks to slide simultaneously.

[0011] By adopting the above technical solutions, one end of the connecting portion is fixed to the rack, and the other end of the connecting portion is closely connected to the clamping portion, ensuring the integrity and stability of the whole structure. The two carefully designed sliding grooves on the mounting seat form a one-to-one sliding fit with the racks, which not only enables the racks to slide smoothly in the sliding grooves, but also greatly improves the accuracy and flexibility of the clamping action. The setting of the driving component is the finishing touch. It is arranged on the mounting seat and can drive the two racks to slide simultaneously, so as to realize the synchronous opening and closing of the clamping portion, greatly improving the working efficiency and the reliability of clamping.

[0013] By adopting the above technical solution, driven by the first rotary driving member, the first rotating shaft rotates stably and precisely on the mounting base. At the same time, the linkage gear fixed on the first rotating shaft also rotates accordingly. This rotation action is directly transmitted to the rack meshing with it through the mutual communication of the cavity and the sliding groove, thereby driving the rack to slide smoothly in the sliding groove. This linkage mechanism not only ensures the synchronous opening and closing of the clamping part, but also greatly improves the accuracy and response speed of the clamping action. In addition, the cavity not only provides sufficient operating space for the linkage gear, but also effectively protects the internal mechanical structure and extends the service life.

[0014] Optionally, an adjusting block is fixedly arranged on the mounting base, an adjusting groove is formed in the adjusting block, and the length direction of the adjusting groove extends along the horizontal direction; a bolt is inserted into the adjusting groove, and the bolt is in threaded cooperation with the rotating seat.

[0015] By adopting the above technical solution, the adjusting block is firmly fixed on the mounting base, and the adjusting groove formed thereon extends along the horizontal direction, facilitating the insertion of the bolt. The threaded cooperation between the bolt and the rotating seat enables the user to easily adjust the position or angle of the rotating seat by rotating the bolt. Thus, the user can precisely fine-tune the clamping part according to the actual working requirements, thereby ensuring the stability and accuracy of the clamping operation.

[0016] Optionally, the mounting base includes two mounting blocks, the two mounting blocks are fixedly connected, a plug rod is fixedly arranged on each mounting block, and the side walls of the two plug rods are in contact with each other; a sleeve is sleeved on the two plug rods, and the outer side walls of the two plug rods abut against the inner side wall of the sleeve; the end of the sleeve is used to place the linkage gear, and a positioning rod for positioning the linkage gear is arranged on the sleeve.

[0017] By adopting the above technical solution, the mounting base is composed of two firmly connected mounting blocks. Each mounting block is fixed with a plug rod, and these two plug rods are arranged side by side closely to jointly support a sleeve. The sleeve is tightly sleeved on the plug rod, and its inner side wall is closely attached to the outer side wall of the plug rod. This not only enhances the overall strength of the mounting base but also provides a stable and accurate mounting platform for the linkage gear. The end of the sleeve is used to place the linkage gear, and the setting of the positioning rod ensures the accurate positioning of the linkage gear in the sleeve and prevents it from shifting or shaking during operation.

[0018] Optionally, the base includes a bottom plate and a cylinder body. One end of the cylinder body is fixedly connected to the bottom plate, and the other end of the cylinder body is open; the rotating seat includes a rotating rod and a rotating plate. One end of the rotating rod is fixedly connected to the rotating plate, and the other end of the rotating rod is rotatably connected to the bottom plate; the rotation driving mechanism is arranged inside the cylinder body, and the rotation driving mechanism is used to drive the rotating rod to rotate; the open end of the cylinder body abuts against the surface of the rotating plate.

[0019] By adopting the above technical solution, the base is composed of a sturdy bottom plate and a cylinder body. One end of the cylinder body is closely connected to the bottom plate, and the other end is open, providing sufficient space for the installation and rotation of the rotating seat. The rotating seat consists of a rotating rod and a rotating plate. One end of the rotating rod is fixedly connected to the rotating plate, and the other end is connected to the bottom plate through a precise rotational connection method, ensuring the flexibility and stability of the rotating seat. The rotation driving mechanism is built inside the cylinder body, and by driving the rotation of the rotating rod, the smooth rotation of the rotating seat is achieved. The open end of the cylinder body closely abuts against the surface of the rotating plate, not only enhancing the structural stability but also ensuring the smooth progress of the rotation action.

[0020] Optionally, a rotating cylinder is fixedly arranged on one side of the rotating plate. An annular groove is formed on the outer side wall of one end of the cylinder body. The inner side wall of the rotating cylinder abuts against the outer side wall of the annular groove. The rotating cylinder is rotatably connected to the cylinder body, and the outer side wall of the rotating cylinder is smoothly transitioned with the outer side wall of the cylinder body.

[0021] By adopting the above technical solution, the base is composed of a bottom plate and a cylinder body. One end of the cylinder body is firmly connected to the bottom plate, and the other end is open, providing sufficient space for the installation of the rotating seat. The rotating seat combines a rotating rod and a rotating plate. One end of the rotating rod is closely connected to the rotating plate, and the other end is rotatably connected to the bottom plate, enabling the rotating seat to rotate flexibly on the base. The rotation driving mechanism is arranged inside the cylinder body, and it is responsible for driving the rotating rod to rotate, thereby driving the entire rotating seat to rotate. The open end of the cylinder body closely abuts against the surface of the rotating plate, enhancing the stability of the rotating seat and ensuring the smooth progress of the rotation action.

[0023] By adopting the above technical solution, driven by the second rotation driving member on the bottom plate, the second rotating shaft starts to rotate, and this rotation action is transmitted to the first helical gear sleeved on the second rotating shaft. At the same time, the second helical gear that meshes tightly with the first helical gear also rotates accordingly. Since the second helical gear is sleeved on the rotating rod, this rotation action ultimately drives the rotation of the rotating rod, thereby realizing the flexible rotation of the rotating seat. It not only ensures the accuracy and stability of the rotation action, but also realizes the efficient transmission of the rotation force through the meshing of the helical gears, greatly improving the working efficiency of the clamping device.

[0024] Optionally, a support is disposed inside the cylinder body, the rotating rod passes through the support, and the rotating rod is rotatably connected to the support.

[0025] By adopting the above technical solution, the support, as the support structure of the rotating rod, not only ensures the stability and accuracy of the rotating rod during the rotation process, but also realizes the smooth progress of the rotation action through its rotational connection with the rotating rod. It not only enhances the bearing capacity of the rotating seat, but also makes the rotation action more stable and reliable. At the same time, the setting of the support also provides a more stable installation platform for the rotation driving mechanism, further improving the working efficiency and stability of the entire clamping device.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the ingenious combination of the base, the rotating seat, and the rotation driving mechanism, the efficient and stable rotation of the rotating seat is realized.

The bottom plate 11 is horizontally arranged, and the axis of the cylinder 12 extends in the vertical direction. The bottom end of the cylinder 12 is fixedly connected to the upper surface of the bottom plate 11, and the diameter of the bottom plate 11 is larger than that of the cylinder 12. The top end of the cylinder 12 is open. A plurality of bolt holes 13 are circumferentially formed on the upper surface of the bottom plate 11, which increases the convenience for workers to install and disassemble the base 1.

At the same time, the second bevel gear 32 that meshes closely with the first bevel gear 31 also rotates accordingly. Since the second bevel gear 32 is sleeved on the rotating rod 21, this rotation action ultimately drives the rotation of the rotating rod 21, thereby realizing the flexible rotation of the rotating seat 2.
