Problems solved by technology
The workpiece rotary overhead device used on the existing drive shaft CV outer ring spline gear rolling machine adopts an umbrella-shaped top, and the umbrella-shaped top is placed on the inner ring of the CV outer ring. In this way, during the production process of the drive shaft CV outer ring, The forged semi-finished product needs to be processed with a large chamfer on the inner ring of the mouth to make it suitable for the use of the umbrella-shaped center. The large chamfer turning of the inner ring of the mouth is time-consuming and laborious, and the cost is high. Therefore, people try to cancel the large chamfer. Corner turning process to reduce the production cost of the drive shaft CV outer ring, thereby reducing the overall vehicle cost
After canceling the large chamfer turning process of the inner ring of the mouth, the existing umbrella-shaped tip and the material return device will not be able to be used, and the existing manipulator for moving the processed workpiece has no material return function and cannot be used, so the investment in the overall transformation The cost is also very high

Embodiment Construction
[0016] The present invention will be further described below in conjunction with specific embodiments.
[0017] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, this embodiment includes a top sleeve 2, a material withdrawal device, a Morse taper shank 12 matched with a transition sleeve 13 on a machine tool, and a control system. The inner tapered surface of the top sleeve 2 is matched with the bullnose of the CV outer ring of the workpiece 14, and the center of the bottom surface protrudes from the connecting shaft 15, and there are eight (six can also be set as required) along the circumference of the outer edge of the bottom surface. 1, seven, etc.) pin shaft light hole 16, the connecting shaft 15 is connected to the Morse taper shank 12 through a bearing, and the Morse taper shank 12 is fixed to the inner hole of the transition sleeve 13 of the machine tool. Preferably, the top sleeve 2 is made of overall quenched GCr15 bearing steel, the hardness reache...

The invention discloses a workpiece rotation supporting device. The device is characterized in that the inner conical surface of a jacking sleeve is matched with the outer circular angle of a CV outerring of a workpiece, and a connecting shaft of the bottom surface center is connected to a morse taper handle fixed in an inner hole of a machine tool transition sleeve through a bearing; each pin shaft of a material returning device penetrates through corresponding pin shaft unthreaded hole in the outer edge of the bottom surface of the jacking sleeve respectively, and compression springs penetrate through the pin shafts and are stopped through stop pieces; a cylinder body of an air cylinder is fixed on a flange of the machine tool transition sleeve, and a pressing plate is fixed at the endpart of a piston rod of the cylinder body of the gas cylinder; a contact is arranged on the piston rod or a piston of the air cylinder, and a travel switch is arranged on the cylinder body of the aircylinder; two air pipe connectors of the air cylinder are connected to an air source through electromagnetic valves correspondingly; and the size of the cross section of the pressing plate conforms tothe conditions that the pressing plate can always be in contact with one or two stop pieces whichever angle the circumferential direction of the supporting sleeve stops at. Through adoption of the workpiece rotation supporting device, large chamfer turning machining is not required to be carried out on an inner ring of the opening part of the workpiece opening, moreover, a manipulator can be completely moved by using an existing finished workpiece, and the manufacturing cost of the workpiece can be greatly reduced.
Description
technical field [0001] The invention relates to a workpiece rotary jacking device, in particular to a workpiece rotary jacking device used on a drive shaft CV outer ring spline gear rolling machine. Background technique [0002] The drive shaft CV outer ring includes the CV outer ring and the shank, which needs to be splined and threaded on the shank. The workpiece rotary overhead device used on the existing drive shaft CV outer ring spline gear rolling machine adopts an umbrella-shaped top, and the umbrella-shaped top is placed on the inner ring of the CV outer ring. In this way, during the production process of the drive shaft CV outer ring, The forged semi-finished product needs to be processed with a large chamfer on the inner ring of the mouth to make it suitable for the use of the umbrella-shaped tip. The large chamfer turning of the inner ring of the mouth is time-consuming, laborious, and costly. Therefore, people try to cancel the large chamfer Corner turning to re...
