Background
After the existing automobile hub is produced, a blank of the automobile hub needs to be processed, and the automobile hub has high casting requirement, thin wall, low yield and high processing requirement. And the current chuck anchor clamps that the blank of treating processing was used, when its jack catch pressed from both sides tight work piece, its contact surface was less, because automobile wheel hub is straight cylindric, if press from both sides tight dynamics too big, then can make the work piece receive extrusion deformation, if press from both sides tight dynamics undersize then be unfavorable for going on of manufacturing procedure. Therefore, the qualified rate of the processed product is low.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is as follows: the defects of the prior art are overcome, and the fixture for the automobile hub, which avoids the extrusion deformation of a workpiece and improves the production qualified rate, is provided.
The technical scheme adopted by the utility model for solving the technical problem is as follows: the fixture for the automobile hub comprises a chuck, wherein a plurality of jaw assemblies are uniformly arranged on the circumference of the periphery of the chuck, each jaw assembly comprises a jaw seat connected with the chuck, a jaw is connected above each jaw seat, and each jaw is arranged in an arc shape corresponding to the automobile hub;
the clamping jaw seat comprises a fixed seat connected with the clamping chuck, and the fixed seat is connected with the clamping jaw through a connecting seat.
According to the automobile hub machining device, when an automobile hub is machined, the protruding end side of the automobile hub is clamped between the clamping jaw and the fixed seat, the side face of the clamping jaw abuts against the automobile hub, and therefore the clamping jaw and the clamping jaw are fixed relatively, and relevant machining procedures are conducted. In the process, the clamping jaws are arranged in a circular arc shape corresponding to the automobile hub, so that the contact area of the clamping jaws when the clamping jaws abut against the automobile hub is increased, the side walls of the clamping jaws are stressed more uniformly, the clamping jaws are guaranteed to be in a straight cylinder shape, and extrusion deformation caused by stress point concentration is avoided.
The circumference is provided with the backup pad on the chuck, the backup pad is located one side of fixing base, the thickness of backup pad is the same with the thickness of fixing base. When the automobile hub is clamped between the clamping jaw and the fixing seat through the arranged supporting plate, the supporting plate provides supporting force except for the fixing seat supporting the end side of the automobile hub, so that the supporting force on the end side of the automobile hub is relatively dispersed, and extrusion deformation in the machining process is avoided.
The clamping jaw type rotating device is characterized by further comprising a rotating shaft, the rotating shaft penetrates through the clamping jaw and is inserted into the connecting seat, the connecting seat and the rotating shaft are fixed through a fixing pin, a pressing cover for pressing the clamping jaw to the connecting seat is arranged above the rotating shaft, and the pressing cover is fixed with the rotating shaft through a positioning pin;
the limiting pin penetrates through the clamping jaw and is inserted into the connecting seat, and the limiting pin is located on one side of the pressing cover. The pivot runs through in the jack catch inserts the connecting seat, realizes the relatively fixed of pivot and connecting seat through the fixed pin, prevents that the pivot from rotating, presses the jack catch to the connecting seat through the gland afterwards, then compresses tightly through the spacer pin connection, prevents that the jack catch from rocking. In order to prevent the claw from fixing the back and rotating along the rotating shaft, the limiting pin is arranged to be connected with the connecting seat, and the matched locating pin prevents the claw from rotating in the using process, so that the using stability is ensured.
Compared with the prior art, the utility model has the following beneficial effects:
the utility model provides a fixture for an automobile hub, which prevents the deformation of an automobile hub blank caused by overlarge clamping force in the clamping process by increasing the contact surface area of a clamping jaw and the automobile hub blank. Therefore, the production quality of the automobile hub blank in the machining process is guaranteed, the qualified rate of machined finished products is improved, and the production efficiency is guaranteed.
