[0001] The utility model relates to the technical field of intermediate shaft forging, in particular to an intermediate shaft forging tool. Background Art

[0002] The intermediate shaft is a component of the steering column of the car, one end of which is connected to the upper column and the other end is connected to the steering gear. When processing the intermediate shaft, hot forging is required. Hot forging can improve the plasticity of the metal by increasing the temperature, which is beneficial to improving the intrinsic quality of the intermediate shaft and making it less prone to cracking.

[0003] In the prior art, the intermediate shaft is clamped by a fixture, and the intermediate shaft is driven to rotate and translate during forging to fully forge the intermediate shaft. However, during forging, the fixture always clamps the intermediate shaft, and the intermediate shaft translation fixture needs to translate synchronously, which has a large driving force for translation, and the portion of the intermediate shaft clamped by the fixture cannot be forged, so the forging is not comprehensive. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an intermediate shaft forging tool, which can solve the problems in the prior art that the intermediate shaft translation clamp needs to be translated synchronously, the driving force for the translation is large, the part of the intermediate shaft clamped by the clamp cannot be forged, the forging is not comprehensive, and the high temperature during forging poses a great safety risk.

[0005] In order to solve the above technical problems, the technical solution of the utility model is as follows: comprising a fixed seat, a clamping rotation mechanism and a translation mechanism;

[0006] A clamping and rotating mechanism is provided on both sides of the fixing seat, and a translation mechanism is provided on the side of the clamping and rotating mechanism away from the fixing seat;

[0007] The clamping and rotating mechanism comprises a hollow hydraulic chuck, a rotating disk, a gear and a rotating motor. The outer fixed sleeve of the hollow hydraulic chuck is provided with a rotating disk, the rotating disk is meshed with the gear, and the gear is driven to rotate by the rotating motor;

[0008] The translation mechanism comprises a translation cylinder which is mounted on a frame, and a driving rod of the translation cylinder is arranged above the top of a fixing seat.

[0009] Furthermore, the hollow hydraulic chuck is a two-jaw hollow hydraulic chuck.

[0010] Furthermore, the rotating motor is installed on the side of the fixed seat, the gear fixing sleeve is arranged on a rotating shaft, the rotating shaft and the output shaft of the rotating motor are connected through a synchronous belt, and the two ends of the rotating shaft are installed on the bearing seat through bearings, the bearing seat at one end is installed on the side of the fixed seat, and the bearing seat at the other end is installed on a support frame.

[0011] Furthermore, the hollow hydraulic chuck is mounted on a support seat through a bearing, the support seat is arranged on both sides of the rotating disk, the support seat is fixed to the mounting seat through a fixing rod, and the mounting seat is arranged on the top of the frame.

[0012] Furthermore, a circular arc-shaped supporting groove is provided on the top of the fixing seat.

[0013] After adopting the above structure, the utility model has the advantages that: the intermediate shaft is placed on the fixed seat for forging, and the intermediate shaft is driven to translate by the translation cylinder during forging to uniformly forge at all places. When the intermediate shaft translates to one side and needs to be rotated, the intermediate shaft is clamped by the hollow hydraulic chuck, and the rotating motor drives the gear and the rotating disk to rotate, driving the hollow hydraulic chuck to rotate, so as to realize the rotation of the intermediate shaft. After the rotation, the hollow hydraulic chuck stops clamping the intermediate shaft, and then the intermediate shaft is driven by the translation cylinder to translate while forging. During forging, the two ends of the intermediate shaft are not clamped and restricted, and both ends can be forged, so the forging is more comprehensive.

[0014] When the intermediate shaft is forged, the translation cylinder only needs to drive the intermediate shaft to translate, and the clamping and rotating mechanism does not need to translate synchronously, so the driving force for the translation is relatively small.

[0016] Figure 2 It is a schematic diagram of the use state of the utility model. Implementation

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. The following embodiments can enable technicians in this field to understand the utility model more comprehensively, but the utility model is not limited to the scope of the embodiments.

[0018] like Figure 1 As shown, this specific implementation adopts the following technical solution: an intermediate shaft forging tool includes a fixed seat 1, a clamping rotation mechanism and a translation mechanism.

[0019] An arc-shaped supporting groove is provided on the top of the fixing seat 1 for placing the intermediate shaft 10 , so that the intermediate shaft 10 can translate along the supporting groove during translation forging without causing deviation.

[0020] A clamping and rotating mechanism is respectively provided on both sides of the fixed seat 1, and the clamping and rotating mechanism includes a hollow hydraulic chuck 21, a rotating disk 22, a gear 23 and a rotating motor 24. The hollow hydraulic chuck 21 is a two-claw hollow hydraulic chuck. A rotating disk 22 is fixedly provided on the middle position of the outer portion of the hollow hydraulic chuck 21. The gear 23 is arranged below the rotating disk 22, and the rotating disk 22 is meshed with the gear 23. The gear 23 is driven to rotate by the rotating motor 24. The rotating motor 24 is mounted on the side of the fixed seat 1. The gear 23 is fixedly sleeved on the rotating shaft 25. The rotating shaft 25 and the output shaft of the rotating motor 24 are connected through a synchronous belt. The two ends of the rotating shaft 25 are installed with bearings and bearing seats. The bearing seat at one end is installed on the side of the fixed seat 1, and the bearing seat at the other end is installed on the supporting frame 26. The rotating motor 24 drives the gear 23 to rotate through the synchronous belt, thereby driving the rotating disk 22 to rotate. The rotating disk 22 drives the hollow hydraulic chuck 21 to rotate. The hollow hydraulic chuck 21 clamps the intermediate shaft 10 to rotate, thereby realizing the rotation of the intermediate shaft 10.

[0021] The hollow hydraulic chuck 21 is mounted on the support seat 3 through a bearing. The support seat 3 is arranged on both sides of the rotating disk 22. The support seat 3 is fixed to the mounting seat 5 through a fixing rod 4. The mounting seat 5 is arranged on the top of the frame 6.

[0022] A translation mechanism is provided on the side of the clamping and rotating mechanism away from the fixed seat 1. The translation mechanism includes a translation cylinder 7. The translation cylinder 7 is installed on the frame 6. The driving rod of the translation cylinder 7 is arranged higher than the top of the fixed seat 1. The intermediate shaft 10 is driven to translate by the translation cylinder 7. During translation, the hollow hydraulic chuck 21 does not clamp the intermediate shaft 10. The driving rod of the translation cylinder 7 can pass through the middle of the hollow hydraulic chuck 21 to push the intermediate shaft 10.

[0023] The rotating motor 24, translation cylinder 7, two-jaw hollow hydraulic chuck 21 and other components mentioned above are all universal standard parts or components known to technical personnel in the field. Their structures and principles can be known to technical personnel in the field through technical manuals or through conventional experimental methods, and will not be elaborated on.

[0024] Working principle: The intermediate shaft 10 is placed in the support groove on the fixed seat 1 by the manipulator for forging. The forging starts from one end of the intermediate shaft 10, and the intermediate shaft 10 is driven by the translation cylinder 7 to translate and forge uniformly at all places. Figure 2As shown, when the intermediate shaft 10 is translated to the right side and needs to be rotated, the intermediate shaft 10 is clamped by the hollow hydraulic chuck 21, and the rotating motor 24 drives the gear 23 and the rotating disk 22 to rotate, driving the hollow hydraulic chuck 21 to rotate, so as to realize the rotation of the intermediate shaft 10. After the rotation, the hollow hydraulic chuck 21 stops clamping the intermediate shaft 10, and then the intermediate shaft 10 is driven to translate to the left side while forging by the translation cylinder 7 on the right. Similarly, after the intermediate shaft 10 moves to the left side, the intermediate shaft 10 is clamped and rotated by the hollow hydraulic chuck 21 on the left side, and the intermediate shaft 10 is then driven to translate to the right side while forging by the translation cylinder 7 on the left side. During forging, the two ends of the intermediate shaft 10 are not clamped and restricted, and both ends can be forged, so the forging is more comprehensive. When forging the intermediate shaft 10, the translation cylinder 7 only drives the intermediate shaft 10 to translate, and the clamping and rotating mechanism does not need to translate synchronously, so the driving force for translation is relatively small.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
